Surprises

2010-01-30T17:45:39+00:00

Once in the while I do something I haven't done for a while and get surprised by how much fun it is.

Today I wanted to get the ITV (Spanish motorcycle inspection), which has been overdue for a while. I didn't do it because I haven't used it for a while and can't used it because I didn't have the ITV.

Turns out that I needed an appointment, so I run some errands. I got a new zoo membership card and cancelled my old gym. This took me with the motorbike down and along the beach. The weather was beautiful and it was reasonable warm. I saw the beach, smelled the sea and felt the Barcelona air in my face.

Whenever I use the motorcycle I get a smile on my face. I really should use it more often. And it makes me appreciate Barcelona more.

Now - most people would say that it shouldn't come as a surprise that living in Barcelona, enjoying the sun and taking a beautiful bike for a spin along the beach is a nice thing. In fact it is probably a dream for most people - including me.

Sometimes you have to take a step back and take a look at your life and realize that you pretty much got everything you need instead of chasing the next dream. You tend to forget that if you are stuck in your daily routine.

By the way: the picture is from today, but not from the motorcycle trip but a mountain bike ride I did in the afternoon.

And now I am going to make Thai green curry and hack some code.

Nice!

Fedora and PHP QA

2010-01-23T17:57:10+00:00

After hearing again about many QA tools at the 2009 PHP Barcelona conference I decided that it would be nice if these would be available through packages on Fedora (and through EPEL on RHEL).

Turns out that the most important ones were already packaged, some needed a new packager, some were waiting for review and a few still need to be packaged.

Here are the once already available, with the packager name:

php-phpunit-bytekit (llaumgui)
php-phpunit-phpcpd (llaumgui)
php-phpunit-phploc (llaumgui)
php-pear-PHP-CodeSniffer (cdamian)
php-pear-PhpDocumentor (cdamian)
php-pear-PHPUnit (xulchris) (this will soon be renamed to php-phpunit-PHPUnit)

These are waiting for review:

php-pdepend-PHP-Depend (cdamian)
php-phpmd-PHP-PMD (cdamian)

These don't seem to have packages at all:

php-phpunit-phpdcd
php-phpunit-phpUnderControl
php-phpunit-PHP_CodeBrowser
phpanalysis
padawan
arbit

Because EPEL is limited to the rather ancient PHP version of RHEL it sometimes contains older versions of the packages available in Fedora. It might be time for a community supported repository for PHP 5.3, for people who don't want to live on the bleeding edge with Remi.

Another thing missing is a package for a continuous integration software like Hudson, arbit or CruiseControl. The reason for this is that they are either really difficult to install or package or are still very much in a alpha version. We are using hudson at work and they do provide a RPM, but it is less than perfect. Arbit looks promising, but probably needs a few more months to be at least in a beta stage.

Give me a shout if there is a package I missed.

2010 New Year's resolutions

2010-01-14T20:33:41+00:00

by boite-en-valise

A new year means new resolutions. But first a quick look back at the ones from last year.

On the fail side: I didn't loose weight, neither did I use my motorcycle more or took a lot more advantage of Barcelona. Success on: sorting out my music collection, travelling somewhere new, doing more programming and blogging a bit more.

Now to the next year. I read a bit about these kind of resolutions and how to be better in succeeding. I probably took too much on in the last year and it is better to have some way of quantifying success or failure. So this year I am just taking on three resolutions. I still keep the failed ones from last year in the back of my mind though.

1. Loose weight (again), but this time with a plan. I will try to loose 0.5 kg a month. On the one hand it doesn't seem a lot on the other hand loosing 6 kg in a year seems too much. I will keep track of this and also keep track about my sport activities. To achieve the goal I will have to reduce my lunches with the opus5 guys and increase my sport activities. I will swap my gym for one nearer to my flat. I also will stop eating sweets and snacks.

2. Reduce time spend watching TV, reading e-mails, blogs, facebook and twitter. I will unsubscribe from as many services as possible. Instead I will spend the time programming, cooking, reading, socializing and doing sports. Not sure how I will put that in numbers, as I don't have them for the past, but I will make something up.

3. Do something about my so called "career". This could mean doing something more fun, working less and/or earning more money. Either at opus5, new projects in my free time or something completely new. I will have to see what comes up, but I have twelve months to decide.

2000 to 2009

2009-12-30T23:38:52+00:00

Now that another decade comes to an end, it is time for me to see if the ten years really were worth the effort. Overall it seems to have been more pain than was strictly necessary.

2000 - it all started quite nice. I just turned 30 and was living in London, just got together with my girlfriend and working for guideguide a very nice start-up which was going quite well at the time. One highlight of the year was a trip to OSCON in California, where I witnessed the beginning of Perl6, which seemed brilliant at the time and now appears a bit pointless.

2001 - will always be remembered for 9/11, someone in the guideguide office heard about it over IRC and we quickly confirmed it on TV. It was also the year where I bought my first iPod, maybe the only trend I ever spotted early. Nobody at the time imagined how either 9/11 or the iPod would shape the future.

2002 - I split up from my girlfriend for a while and decided that this would be the right moment to start drinking alcohol again after ten years.

2003 - guideguide was scaling down a lot now and I had to fire lots of people, which was probably one of the most stressful episodes of my business life so far.

2004 - with not much left of the company I decided I could as well move to Barcelona and work from there. It turned out to be a lot of fun and a lot more relaxed than London. It was also the year where I got ill and fixed up again.

2005 - a bit of work, a bit of travel, a lot of recovery

2006 - I quit guideguide after lots of years. It was a difficult decision, but nobody of the old gang was still around, so I didn't feel too bad. I was also looking for a local job and just being employed for a change. I used the rest of the year to chill and enjoy Barcelona.

2007 - Found a new job at opus5, learned lots of new stuff. For some reason the founder left after I just started, is it me ?

2008 - whatever happened to 2008?

2009 - I decided to stop drinking again, turned out to not be my thing after all. The economy made this year really interesting and I hope it will turn up some new opportunities in the future. Oh, and I turned 40 and I am looking forward to my mid-life-crisis, but that is the topic of another post.

And finally thanks to everyone who made these years more fun then they sound:

my girlfriend Cat, who makes everything more lovely
my family: Kathrin, Thomas, Klaus and Ulla, who helped me through some rubbish
Mikel, who brought me to London
the guideguide guys: Andy, Adam, Alex, Marc, Rob, Jasper, Ben, Luke, ..., who made me learn a lot and fast
The Londoners: Anita, Justin and Graham who made it more fun
Opus5: Dennis & Pablo, where I learned a lot of stuff I didn't wanted to know

So lets see what the next decade brings, maybe a new start and the opportunity to do completely new mistakes!

Here are some random pictures from the past ten years

Fedora 12

2009-12-19T15:28:13+00:00

Fedora now has been out for a few weeks and I can summarize my experience with it a bit.

I have installed it on four machines:
- netbook (Eee PC 901) new install with a 32bit live USB stick
- media centre (ancient custom AMD Duron) upgrade with the 32bit DVD
- home PC (AMD Phenom 9350e) upgrade with the 64bit DVD
- work PC (Dell Intel) with 64bit preupgrade

I would have preferred the preupgrade on all machines, but I am using RAID on some of the machines and preupgrade doesn't like /root being on RAID. But the upgrade went smooth in all cases, so I don't really mind.

I also changed the graphic card in my work PC to an ATI HD3450, so I can finally use the desktop effects with an open source driver.

What works out of the box

Desktop effects on the netbook, home and work PC, with either the ATI card or Intel on-board graphic chips.

Pulseaudio with USB or bluetooth headset. I use it mainly with Skype, which is the only non open source software left on my computers (I blame peer pressure).

PHP 5.3.1 and MySQL 5.1.40, which meant I have stopped using the Remi repository for now.

Automatic bug reporting for program crashes and kerneloopses. This should make the quality of future releases even better, even though bugzilla is pretty much swamped with bug reports now. But I think it is always better to have more information than less.

CPU speed scaling finally works. I had to fiddle with the BIOS settings a bit to enable Cool and Quite and some other power management settings.

What doesn't (or didn't work)

I had some problems with pulseaudio crashing after installing the ATI card, but putting a "blacklist snd-hda-codec-atihdmi" into /etc/modprobe.d/blacklist.conf fixed it. I found the fix on bugzilla.

I am still not able to play my Homeworld 2 CD with either Wine or VirtualBox, I think the drivers are still not good enough to support the OpenGL needed for the game. It also crashes after a while in VirtualBox. Radeon bugs currently hold the top spot at kerneloops, which makes a fix more likely.

If you use an Eclipse (or Azureus), which didn't come with Fedora some of the GUI buttons don't work. This is caused by a change in GTK and a workaround is to set GDK_NATIVE_WINDOWS=true before you start eclipse. This is also mentioned in bug 540956.

I bought a D-Link DWA-547 Wireless N PCI Card for the media centre in my effort to upgrade the flat to 802.11n, which I just can't get to work. It is either slow or crashes the whole machine without any way to get to the kerneloops. I probably have to find a different card to get it working. But wireless cards always have been a problem.

My Bit

I am also trying to contribute more to fedora by building packages and doing package reviews. After the Barcelona PHP Conference I decided to build RPMs for the PHP QA packages by Sebastian Bergmann and others. Turns out that most of them are already available or up for review, so I applied as co-maintainer and did a package review. Remi has a good overview of PEAR packages in Fedora.

The other big project which will probably take a few more years is the odyssey of packaging symfony, this turns out to be difficult because symfony bundles a lot of libraries and they need to be separated into their own packages. The good thing is that this will bring these libraries into Fedora (and eventually EPEL) too. So far I managed to get Doctrine in and the Swift Mailer is up for review. Symfony itself won't get into EPEL, because it requires a newer PHP, but it will work with the Remi bits.

You can find a list of my packages in the Fedora package DB and also of the ones I co-maintain. Still rather short list at the moment :-)

Summary

Probably the best Fedora upgrade and usage experience I had so far. The main problem is still the hardware, the software itself works perfectly and for my usage I don't really need anything more at the moment.

Finally a rather boring screen shot of my desktop:

Barcelona PHP Conference Day 2 #phpbcn2009

2009-10-31T18:50:37+00:00

Even shorter summary of the second day of the Barcelona PHP conference. (see here for day 1)

Zend_Cache... by Enrico Zimuel

This was a introduction to the cache component of the Zend framework. It pretty much does what you expect: it wraps the common types of caching ( file, apc, memcached, ...) into a common API to make them easy to swap and use. It also has helper objects to support caching of PHP output with output buffering.

The State of Quality Assurance Tools for PHP by Sebastian Bergmann

Mr. PHPUnit gave a short introduction to testing and the PHPUnit framework. He then introduced some of the other tools that can help you with quality metrics of your software, these were:

phploc - counting lines and more
phpcpd - finding duplicate code
pdepend / phpmd - static code analysis
phpcs - code style and static code analysis
bytkit-clu - more analysis

He then continued to show how you would automate running these and include them in a continuous integration tool like CruiseControl with phpUnderControl or Hudson.

It was a good talk and gave an introduction to the whole process of quality assurance for projects.

Slides

Continuous Integration by Davide Mendola

Another talk about CI, which gave a bit more insight into the tools but because of the previous talk a lot of stuff was repeated and not a lot new information introduced.

One thing was obvious though: nobody is completely happy with the current tools, because they are all Java based and don't fit 100%. There seems to be a market now for new PHP CI tools and I am sure we will see some showing up in the near future. I would also see some of these using a MVC framework instead of being developed from scratch.

And for the hecklers in the back shouting "Xinc" : no release or commit since one year ? Maybe someone should pick that up again. :-)

Symfony 2.0 a sneak peak by Fabien Potencier

Fabien gave a very fast run through some of the new components and designs for Symfony 2.0. A lot of things will change and it will be difficult to port older projects, especially if you have business logic outside your models.

He spent a lot of time explaining the dependency container component and how and why it will be used in Symfony 2.0. I am a bit afraid that this will make things more complicated and difficult to debug or work with in an IDE. I usually don't like to see logic into configuration files, but now I at least understand why he is doing it and what advantages it will have in Symfony 2.0. I just hope I won't see these in every object and sometimes just simple injection is used.

I am looking forward to Symfony 2.0 though, I just got one suggestion to reduce Fabiens work a bit: throw away the Lime testing framework and use PHPUnit. Lime will never match the PHPUnit features and everything you need which isn't provided by PHPUnit yet is probably easy to integrate.

Open Classifieds by Chema Garrido

This was a refreshing different talk by the lone developer of Open Classifieds, which is an open-source classified web application. He developed it from scratch without using any framework (Rasmus would love this), it is very much in the spirit of the KISS talks of this weekend.

If I find time I will certainly have a look at it. And before the security concious object orientated dependency injecting agile caching crowd complains: give the guy a hand with a bit of code review if you find the time.

Barcelona PHP Conference Day 1 #phpbcn2009

2009-10-30T23:59:23+00:00

First day of phpconference.es is finished and it was very enjoyable. The location was the same as last year, so was the quality of the organization. I saw six talks, here are small summaries:

KISS by Derick Rethans:

Pretty much a beginners, introduction and common sense talk. Most of it not even directly relevant to PHP. A bit of a disappointment, might have been more interesting for customers than developers.

No slides up yet, but they were very similar to these: Kiss Phpnw08

Trees in the database by Lorenzo Alberton:

A very interesting talk about ways to store trees in a database, which is something everyone has to deal with at some point. He started with the simple "parent-child" method and showed some of the problems with it. Then went through some better versions like the "nested set model", which is for example used in Doctrine. He finished with the "nested interval model", where I think I saw some smoke coming out of some heads around me (and probably mine).

Finally he showed how trees are supported directly in some of the databases and the SQL99 standard.

It would be nice if the "nested interval method" would end up in Doctrine too. And maybe support for the database extensions too, though at the moment I just care for mysql and here is a link with some information how to do the stuff there.

The slides are here: Trees in The Database

Talk by Rasmus Lerdorf

Rasmus did a two part talk. The first part was about performance and ranged from suggestions to replace lots of expensive library calls with simple echos to introductions into strace, valgrind and xdebug. He likes to complain about frameworks and abstraction, for which he got some angry looks out of the framework corners.

Second part was about security, where he showed some problems through examples in live sites. Because someone twittered about it before he wasn't able to show the ".svn" files on elpais, but he managed to show an interesting XSS exploit on another newspaper page. Then he went on about the "filter" extension, which I don't like much because I see it as just another Swiss army knife function for something which should belong into PEAR libraries or frameworks. One good thing about it is that you can switch it on globally so that you can block most attacks automatically and skip it for special cases, this reminds me a bit of magic quotes though and how much I hate those.

It was very interesting and he is a very charismatic talker, which helps obviously. The questions after the talk came mostly from the framework guys who pointed out that the security part is easier to fix with one of those, because you have centralized points where you can put your security hooks.

And the PHP filter extension is a bit like a "security framework" only that most PHP programmers won't be able to see or change the source.

Most of the people in the audience have different problems to solve than Rasmus, because we need to build websites quick and we don't have the amount of hits that Yahoo gets. But he gave some good pointers and I certainly get my Xdebug profiler out more often.

Ajax for scalability by Erik Schultink

Erik works for Tuenti, which is a facebook clone for the Spanish market. They have millions of hits and more or less the same scalability problems as the original. They use ajax to build the complete page and basically just retrieve json from their servers. He described everything they do to increase their performance, from the server farm set-up, CDN usage and monitoring to the distribution of the image sizes on the website.

This was a very good talk and I wish I had their problems or they would have an office with an opening in Barcelona :-) These are your guys if you want to work for facebook, but live in Madrid.

I wish I had a link to slides, but I don't

Integrating Zend Framework and Symfony by Stefan Koopmanschap

Stefan is the community manager for Symfony and gave some examples of integrating Zend components in Symfony and Symfony components into the Zend framework. He gave some small examples of both ways and introduction to some of the nice components of both worlds.

I definitely have to look more into the Zend framework and see if I can pick some nice things up. The twitter component would have made my life a lot easier while developing krass sets

And there are slides up for the talk.

PHundamental Security by Hans ZaunereDamien Seguy

As the title said: basic security stuff about the typical injection. The slides were a bit confusing at times. Good stuff I picked up: some more evil PHP functions to circumvent register_globals=off, using the tokeniser to find problematic code and using statistic analysis to find problems.

He also mentioned some black-box tools to help find problems in websites, but I forgot them and I can't find slides either.

Tomorrow is day 2, which looks promising again with talks by Herrn PHPUnit and Monsieur Symfony and some other goodies.

New hobby: OpenStreetMapping

2009-09-27T14:43:06+00:00

I always loved the idea behind OpenStreetMap. Mostly because of my open source experience and sites Wikipedia, these show that with enough people doing a little bit of work in the area they know, it is possible to create results which are better and more free than the conventional commercial offerings.

I remember the time in London, when we had our little start-up and needed location maps for our customers and couldn't find a good provider for this (there was no google maps or map24 at that time). So fools that we were we decided to write it ourself. We got the raw data on CD from TeleAtlas and one of our programmers got pretty far with a renderer. But before we could get anything useful map24 produced a much better version which we started using. But I always have been frustrated by the lack of open map data and open source renderers.

With OpenStreetMap this is now all in the past, the maps are up to the quality of the commercial services in many areas now and the renderers are very good too. In fact the maps are so good that I haven't really had a chance to contribute myself.

But now with my frequent trips to Tibidabo with the mountain bike and my GPS phone I noticed that the OSM maps for that area are full of white spots and are missing most of the hiking and mountain bike routes through the forest, but also some of the tertiary roads.

So I exported some of the tracks I had so far and uploaded them to OSM, this gives everyone working on OSM the chance to use these to create roads on the map. To do this I downloaded merkaartor, which makes it very easy to create roads and places and tag them correctly. There is a Fedora package available, so it was a very easy install. You can also use this to create maps even if you don't have a GPS yourself, just by using the yahoo satellite images or tracks other people made public.

Yesterday I did my first ride especially for OSM to trace some roads and tracks which I haven't travelled with the GPS yet. It took me three hours to ride 30km, which was a lot of fun.

One thing I found difficult is choosing the right tags for the roads and tracks. But it looks good at the moment and if it turns out to be incorrect it is always possible to change later.

Here is an image of the area I am currently working on it is the whole Park de Collserol a, around the Tibidabo. I have traced most of the small dotted lines in the current target area and some of the residential and tertiary roads. You can also see the same map on openstreetmap.org.

Turns out this is probably one of the perfect hobbies for me at the moment, as it combines open stuff, mountain biking and gadgets. Now I somehow have to get some programming in there too.

2009-09-22T15:30:06+00:00

Another look at my New Year resolutions. I decided to do them every four months now, every three was a bit much.

loose weight
fail - I am doing more mountain biking and eat sensible, but I gave up on the gym. Working out with my N79 Active turned out to be a lot of fun.

use my motorcycle more
a little bit more use, small trips and some usage in town. Now I need to get a new ITV.

sort out my music collection
all done. Tapes and CDs are digitized and I got rid of most of the duplicates. Music from podcasts is still a mess, but that can wait for another day.

travel somewhere new
Success - We went to Cadiz for the summer holiday and also checked out Tarifa, Tangier and Gibraltar. I would like to do another weekend trip somewhere, either with the bike or a weekend plane trip.

do more programming
not much happening at work. I started the twitter / tractor top10 website, which was fun. I also took over some packages for Fedora and have two more on review. I also did some programming for the digitization of the tapes and little things on older projects. I would count that as a success.

take more advantage of Barcelona
Saw some arty film stuff, went to the beach more and took full advantage of Tibidabo. Also two trips to the cinema so far: Watchmen and District 9, which are both great. This week is Merce and soon the Air Show and the Red Bull Air Race.

blog more
a little bit better. I think once every two weeks is probably my rhythm :-)

Summer Holiday Cádiz

2009-09-13T16:27:46+00:00

Last week Cat and I went to Cádiz for our Summer holiday.

It was just a week this year and we didn't really decide what to do this year until the last minute. It was either a motorcycle tour around Catalonia, France or a short flight to somewhere in Europe.

Because Cat likes the Atlantic and we had never been to the very South of Spain we decided to take the Trenhotel night train from Barcelona to Cádiz and rent a car there for a few days. We booked train and car and I also bought a backpack and some trekking shoes for the trip.

Because the booking was done in the last minute we didn't get a sleeper cabin, but the sleeper chairs are OK too. The train goes from Sants station to the centre of Cádiz. The first night we staid at the wonderful Hotel Argantonio , but because we didn't book we just had the room for one night. We had a look around the town and the next day headed south.

A lot of the coast of Southern Spain is filled with horrible new holiday homes and you won't find nice villages, but the beaches and the surroundings are rather beautiful. We stayed at camping sites, which were all nice and usually had access to the beach.

We as far as Tarifa and after a bit of sightseeing got the idea of taking a ferry to Tangier .

As it turned out you need a passport for this unless you go on a packaged tour, then an id card is sufficient. The tour was packed full of "shopping opportunities", like spices, gifts and carpets and other stuff we didn't really want. But because we didn't have a choice and Tangier is a nice place it was worth the trip. I would have liked some time to explore the city myself, but you would need more than one day anyway. One word of advice: if you enjoy the western tradition of toilet paper, you better bring your own.

The last day we did a quick trip to Gibraltar and then back north to a camping ground not far from Cádiz to make it easy to drop of the car and spend some more time on the beach and in the town.

Overall a very nice holiday, with a bit of everything and also a bit exhausting. I would do it all again, but maybe book the hotel earlier and go with the motorbike.

You can see more picture in my facebook album.

Nokia N79 Active

2009-09-04T22:11:43+00:00

Recently I started using twitter, facebook and blogs more and I got a little bit annoyed that I couldn't update those sites with my mobile phone. And then my digital camera died on me, which resulted in no new photos by me in the last couple of months. The final point which made me want to get a new fancy phone was me getting lost on Tibidabo without a GPS.

My old phone is a Ericsson t39m, which is one of the best mobile phones ever made. It was one of the first phones with bluetooth and does stuff like email, WAP & T9. It also supports lots of accessories, like different sized batteries, different antennas, docks and travel chargers. It also pretty small and has a nice monochrome screen.

But there comes a point where you need a new toy and after looking at all kind of phones I finally came up with a list of requirements:

3.5 mm headphone jack
digital camera > 3M
GPS
small and light
not too expensive, because it might get stolen here in Barcelona
normal phone keys, no touch phone
some way to program for it
WLAN
bluetooth
USB storage support for photos and music

This ruled out pretty much most of the phones including the iPhone, which was out of the question anyway, because my recent experience with iPods and Linux.

At one point I discovered the Nokia N79 Active, which was announced beginning of the year. It also has one nice additional feature which is was the real selling point for me: it comes with a Polar heart-rate belt.

Buying one turned out to be a bit more difficult then I hoped. First it was just released in Finland, Sweden and South Africa, and not available on-line. It was announced in Germany, but the date got pushed back every month until they finally took it off their website. Then it got released in the UK and was available on the Nokia on-line shop, but they obviously don't deliver to Spain. Finally a friend of mine in the UK ordered it for me and forwarded it to Barcelona.

Now I have it since a little bit over a month and are fairly happy with it. I use it every day as my phone, for photos, web browsing and twittering.

Together with the Nokia Sportstracker website and software it is also brilliant to track your sports activity, which is in my case mainly cycling and mountain biking. Here is the information about my last long ride on Tibidabo: 4h on Tibidabo

Here are some other things I like about it:

pretty light and small for a smart phone
some good software available, like GPS tracking (AFTrack), twittering (Gravity), Putty
there is a Python version for it
some nice google stuff, like Maps, Latitude, Youtube, ...
good Nokia mapping software
the podcasting client is nice and you can add your own OPML files as directories
contacts & calendar can sync with google
camera is good enough

And some stuff that is rubbish

the software and menus are structured very strange, you can reorder them but some stuff just makes no sense at all. The worst bits are all the different settings and preferences. Others think so too
there is a "Media" button & menu, which doesn't make any sense
the whole Sportstracker thing seems to have a unsure future
the WLAN and 3G selection should just do the right thing, like the iPhone does
some non-Nokia software has a completely different UI, the google apps and opera for example
OVI (Nokia online services and app store) is a mess
it crashes sometimes, even doing simple stuff
out of the box it comes with three different types of maps (google, OVI, Sportstracker)
annoying start-up screen & sound and horrible ring tones

Overall I am happy though, because I had rather low expectations as most mobile phones I had in my hand in the last couple of years were pretty rubbish. Except of the iPhone, which had the first good user interface for phones since the rotary dial, but it just was not right for me.

Gravlax

2009-08-01T00:11:54+00:00

Simple gravlax recipe:

two pieces of salmon with skin on
dill (handful)
sea salt (two tablespoon)
crushed pepper corns (two tablespoon)
sugar (one tablespoon)

cut dill, mix with salt and pepper. Put one piece of salmon skin down on large bit of cling-film. cover with the mix, put other salmon on top. wrap everything tight in cling-film. Off into the fridge and put something on top to weight it down.

Now the difficult bit: you have to wait at least one, better two days and turn it every once in a while.

Nice and easy snack for the summer.

The Big Digitization Of Cassette Tapes

2009-07-05T16:51:38+00:00

Today I finally finished digitizing all of my techno and house cassette tapes. It took me a little bit over two months. Here are some statistics:

290 "a" sides
278 "b" sides (sometimes the tapes broke after the first side)
12 tapes which unusable
41 tapes which turned out to be copies of CDs which are available to buy
5 tapes were copies of stuff I have also on CDs which are not available to buy
8 tapes had unreadable labels
249 GB in 16 bit 48khz WAVE files
the whole list

I probably still have some tapes flying around somewhere and my girlfriend also has some, but the vast majority of my music is digitized now. The music is mainly mixed techno and house DJ sets, from my friends like DJ Gomez, Motik and Nitin. A lot of sets are recorded from radio like HR3/HRXXL and Hithouse Stuttgart and in clubs around Stuttgart and Cologne. The most popular DJs are Sven Vaeth, Roland Casper, Richie Hawtin, DJ Hello, Dag, and Laurent Garnier.

I used my little python tapetransfer script, which I wrote for this purpose. It basically waits until there is music and then records until there is a longer break, which is perfect for DJ mixes and rubbish for normal music CDs. I recorded everything with the same level, which means that some tapes are really quite now, but the alternative would have been to play every tape twice. If it turns out that some tapes are too quite I will record them again in 32bit and normalize. I probably write another script to find out the level of each wav file.

In the end it didn't take me as long as I expected, I usually managed to do one tape before work and maybe three in the evening and a bit more on the weekend.

All that is left now is converting them to flac and mp3. The files have to be tagged and named more consistent. Another idea is to also scan pictures of all the tapes and add this to the music files.

And listening to all of them again, but I already found some real gems.

Quick weekend hack: statistics on Richie Hawtins DJ set tweets

2009-05-03T12:50:22+00:00

Richie Hawtin recently started to post the records he is playing on twitter. He is using Traktor while he plays, which now has a new plugin which allows this functionality. Others have posted about this and what it means for techno music enthusiasts, DJs and the music industry.

I think it is one of the few good applications of twitter and I decided to hack something together to display this information in a little bit nicer way.

I created a site at sets.krass.com which gets the tweets from twitter and generates a list of DJ sets and a top10. As Hawtin is the only DJ I know who uses this application the overall top10 is not much use, but it shows the potential.

This is my first project using symfony and I was surprised how good it worked for this task and how easy it is to get started.

If you have problems accessing the site, come back a bit later, there seems to be a problem with one of my secondary DNS servers.

Some thing I have planned for the future:

add links from the tracks to krass.com, discogs and co. It is a bit difficult, because artist names are not always present or correct
add more DJs, if you know of someone also using this kind of tweets give me a shout
make the combining of tracks into sets better (at the moment I just use the day) and allow more sensible names for these
pages with tracks listed by artists and links to the artist pages

That is enough for today though, because it is bloody hot here in Barcelona.

Berlin, Berlin ich fahre nach Berlin ;-)

2009-04-21T23:40:39+00:00

Only two more weeks and I have to leave Munich and move to Berlin. I am a kind of sad about it. I really love my flat here! I love my friends and I love the nature around Munich. But I also look forward to Berlin, my new flat, my new area Kreuzberg and to all the exciting events waiting for me ;-)

Spaghetti with clams and aioli

2009-04-11T21:00:23+00:00

New recipe for me, inspired by something I saw Rick Stein doing in some cookery show.

Put clams in a hot pan, add a cup of white wine. Cover and cook until they opened. Drain with a colander, but keep the liquid. Discard the clams which did not open.

Put some spaghetti or tagliatelle into a pot with boiling water and cook according to package instructions.

Meanwhile put one sliced onion and some sliced garlic into a pan with olive oil and fry them until soft. I added some small and medium peeled prawns and some leftover cod pieces. Then add the clams with shells and the white wine liquid you kept. Finally add some aioli. Season with salt pepper and herbs.

Reduce this a little bit. Add the pasta straight from the other pan and stir until it is covered.

The result should be creamy with not too much liquid.

Ingredients (for two really hungry people).

200g pasta
clams (four handful)
1 cup of dry white whine
1 onion (sliced)
4 cloves of garlic (sliced)
two table spoons of aioli
some prawns or other white sea food
olive oil
salt
pepper
herbs

Quarterly resolutions review

2009-04-05T12:18:53+00:00

Ok, lets see how I am doing on my New Year resolutions:

loose weight
not much to see there. I think it is mainly because I am not going to the gym enough and haven't started mountain biking yet because of various illnesses. But I am teetotal now, so that should make a difference in the future.

use my motorcycle more
that is a no. I blame it on the weather.

sort out my music collection
ripping CDs is done and I have deleted all mp3s from questionable sources. I also removed all duplicates, which was quite a bit of work. I still have to digitize my tapes, but I wrote the software for it and have bought a new tape deck for the task.

travel somewhere new
we have planned some kind of summer holiday, but we don't know where yet. Cat prefers the Atlantic either France of Spain, but I would love to see some the south of France and some of the island in the Mediterranean. As I want to go with the motorcycle, this are pretty much the areas we can travel if we have one week of holiday.

do more programming
I did a bit of work on my small open source projects. I also have three packages in Fedora now. At work I started to help sanego.de, which is a rather busy health portal for the German market. This is fun, because it is just programming without a CMS or lots of HTML to get into my way.

take more advantage of Barcelona
fail

blog more
better than last year, but still not good. I also started to use twitter more, which is nice.

According to wikipedia I am doing not too bad, but there are still nine months to go...

Radio & Talk Podcasts

2009-03-06T19:34:09+00:00

This is the second list of podcasts. These are all the talk, radio and video podcasts I listen too. At the moment I have a bit of a problem of lacking behind. This is a sign of me skipping the gym to often.

It is a mix of news, technology, documentary and comedy. Most of the podcasts are from the BBC

Amsterdam

2009-02-23T15:05:52+00:00

View Larger Map

I returned yesterday from a four day trip to Amsterdam. As I met my Cat there we tend to go every February and celebrate our anniversary.

The last years we stayed at the Winston Hostel in the red light district, but last years experience was so bad that we looked for something new this time.

We found the Sunhead 1617, which is a nice small B&B in the centre of town. I tried to book the red room, which has views of the canal, but because of some confusion we ended up in the yellow room. I suggest you book early and get the red room, because our room contained some kind of boiler which was extremely annoying. And bring backpacks instead of a suitcase, because the stairs really are steep. Otherwise the B&B was perfect, the rooms was nicely decorated, the bed comfy, the breakfast was very good with home made jams and fruit yogurt. Our host Carlos was also very nice, even though we annoyed him on the first day by getting up at eleven for a very late breakfast.

Amsterdam tends to be a bit wet and cold at this time of the year and this was no exception. But it gave me a good excuse to spend most of the time shopping, in coffees and restaurants. The shops seemed even better than the last time, but maybe that was because of the area around the Sunhead. Here are some of the restaurants we checked out:

wagamama: I can't keep Cat away from wagamama and the chicken chilli ramen were perfect as usual. But the raw juice seemed a bit on the orange juice side and the raw salad was a disappointment. I really have to learn how to make the salad from their cookbook and maybe they should have to look into that one too. The service wasn't very good either, but it was very crowded.

Top Thai: This one was recommended by Carlos and it excellent. The food was near perfect and the restaurant is also pretty small and cosy. There are obviously a lot of asian restaurants in Amsterdam, but I think this one belongs to the top.

Some pancake restaurant in the center: I can't remember the name now, but it wasn't any good anyway, neither the service or the food. If you like pancakes I would recommend the Pancake Bakery, which is much nicer.

De Struisvogel: A tiny romantic restaurant which serves a three course set dinner which includes a very good ostrich steak. I had a homemade poultry pate with bruchetta and then a flemish stew, both very tasty. The stew was a bit on the salty side, but maybe that is just me.

None of the restaurants allowed smoking, which was a nice change from Barcelona, where the smoking ban is not enforced enough. I personally can't understand why anyone would allow smokers in their restaurants and just hope this will be sorted out in Barcelona soon too.

I think next time we should go in the summer, so we can see a bit more of the city and the parks. And I also want to check out some of the museums if they every finish the renovation of the main ones.

back from snowboarding in ehrwald

2009-02-01T12:36:59+00:00

ehrwald is a ski resort close by munich and it is great fo snowboarding. today we had great weather and good snow. i hope that it will snow a little bit more in the next weeks.

eZ winter conference

2009-01-29T18:57:01+00:00

Today I went to the eZ International Winter Conference here in Barcelona. Mainly because it was local, free and I quite liked the last PHP conference I went to. The location was the old centre of commerce near the Estacion Francia. It is a beautiful location and I am glad I was able to see it from the inside once. The conference room was certainly fit for the G7 or signing of peace treaties. (I will try to find some pictures on flickr later).

I first have to say that I have not used eZ publish or the eZ components, but I have heard of both and was especially interested in the components.

At the company where I work we are currently looking for a new content management system. We are using typo3 for most of our projects and some are done in cakephp for the ease of development. Ideally we would like something which provides an easier way to develop, a CMS which can be used by our customers but has still enough features to be flexible.

The talk about the eZ components was very good and I like the bottom up approach to the MVC support. The talk was by Derick Rethans, who also did the xdebug talk at the php conference last year. There was also a good talk about the eZ Find extension, which allows full text search implemented with Solr.

The last talk focused on the future direction of eZ publish, especially version 5.0. This version will be a refactoring of version 4.x and they want to move to a more micro kernel with extensions approach instead of the monolithic one they have at the moment. This version should also use more of the eZ components and the MVC features. The 4.x branch will be maintained in parallel until version 5 is established.

To anyone who follows the typo3 development, this might sound familiar. typo3 also has a version 5 in the works, which is a complete rewrite (not refactored), uses a MVC framework, will be developed in parallel to the 4.x branch and nobody knows when it will be finished.

The difference is the development model. While typo3 is developed in the open by individuals from multiple companies or private individuals, eZ is produced in house by a business with a clear focus to make money. From what I have seen so far I like the eZ product more, because it is developed with a clear use case in mind and with the knowledge that you have to stay with your feet on the ground. typo3 tries to use every design pattern and development method on the planet, it seems to be more like a way for the developers to show their knowledge instead of thinking of the end user or developer.

Both CMS frameworks also make the mistake of reinventing the wheel. PHP already provides nice libraries for database abstraction, template systems and other things which are implemented again by both frameworks. eZ seems a bit better in this regard by just providing wrappers for existing libraries.

I will have a closer look at the eZ components and will suggest evaluating eZ publish in our company. So overall a success for eZ I would say.

Snowboarding Laax

2009-01-27T20:03:10+00:00

Yesterday Cat and I returned from our week long snowboard trip to Laax.

First we flew to Stuttgart and visited Marion and Bernd in Balingen, where we met up with the other guys who took us by car and van to Laax. The weather on the way looked a bit disappointing, with not much snow until the last corner to Laax.

We were staying at the same hostel as last time, it is the Mountain Hostel Laax. It is situated in the middle of the ski area at the first stop of the cable car. The accommodation and food is basic, but you don't really need much more anyway. This time we had a two bed room, which was a lot nicer than the sharing with four people of last year. The room could have done with more changes of towels or linnen though.

But the main disappointment of the holiday was also related to the Hostel, because there was a very relaxed attitude to property rights. During our stay my iPod Classic 160GB and a Sony digital camera got stolen out of our rooms and a pair of new snowboard boots from the hallway. For the iPod and camera I suspect the cleaners, because they vanished on the day brought new towels and the rooms were locked all the time. The boots got stolen during the night, so it must have been one of the employees or hostel guests, as nobody else can come or go at night time.

But now to the good bits. The weather turned out to be brilliant, the first few days we had non stop snowfall. This meant the visibility was not that good, but the snow was perfect and I discovered how much more I love deep snow and freeriding compared to prepared slopes. During the week there also no queues at the lifts which are perfect conditions for stressless fun. At one day there was also a lot of fog, which reduced the visibility to about 10 meters, but even that was fun.

I used the week to work on my snowboarding and I am a lot quicker now. I also learned turning 360 degrees while riding, riding backwards and 180 while riding slow. Cat also found a little kicker to do small jumps just off the slope. Cat is still quicker than me, but I can always blame the age difference. And I didn't break anything this time - brilliant!

I would love to go boarding again this year, but I am to broke to afford another week. And now I also need to replace the iPod and my own broken Sony camera.

Cat and Rafael have put some pictures on facebook, so check there.

I also managed to read some books while on holiday:

Unzipped by Courney Weaver - which was not very good, a bit like Sex in the City with more sex and less shoes. I read the German version, which probably made it even worse.
Head First Design Patterns - an illustrated introduction to design patterns, which I borrowed from work. The concept of the book is a bit strange, with lots of pictures and comic style text balloons. But it explains the same patterns as the Gang of Four book and with good Java examples. I certainly learned some stuff.
The Voyage of the Beagle by Charles Darwin- I am not finished with this one, but Darwin was proper adventurer and explorer. It is amazing how much things he saw and how he was able to explain the smallest details of all the plants, animals and humans he saw on his travel.

Weired conversations

2009-01-14T15:11:54+00:00

Strange conversation on yahoo messenger. I used Eliza for the replies, but the guy gave up too quickly.

(1:58:24 PM) hidden: I'm really sorry that I said those things, honey, but I just lost control of myself. You know as well as I do that I have struggled with anger since my childhood, when my mom died and my dad started to abuse me. I just want you to know that I'm sorry, and that you should take me back. And if your answer is no, then you're a giant bitch.
(2:01:23 PM) cdamian: Do you wish that my answer is no then your're a giant bitch?
(2:01:50 PM) hidden: porn
(2:02:06 PM) cdamian: Please go on.
(2:02:34 PM) hidden: no
(2:02:47 PM) cdamian: You are being a bit negative.

neues jahr neues glück

2009-01-11T01:36:49+00:00

nachdem ich 10 wundervolle in stanton verbracht habe - zur info kein ideales snowboardgebiet -
bin ich jetzt bereit einen neuen job zu suchen. es ist schon faszinierend das die wirtschaftskrisen immer alle 7 jahre sind.
man müsste sich überlegen ob die topwirtschaftsleute alle so religiös sind und sich daher an die heuschreckenplage halten oder ob die bibel nicht nur gleichnisse sondern doch etwas wahres beinhaltet?

vielleicht noch ein paar worte zu stanton ;-)
schon der name stellt klar, dass dieser ort von engländern, amis, australiern und neuseeländern besetzt ist. für österreich sind die preise sehr gesalzen und die restaurants eher mässig. dafür hat man sogar über silvester kein überfülltes skigebiet, bei den liften muss man kaum anstehen. weil es sehr viele flache autobahnen gibt, muss man als snowboarder des öfteren laufen...
ansonsten hatten wir jeden tag kaiserwetter und tollen schnee.
da wir mit eine gruppe engländer da waren, sind wir in die zünftigen bars gegegangen, allen voran alibi direkt auf der dorfstrasse. ich denke ausser ein paar alten engländern, den freunden des besitzers und uns hat noch keiner das alibi zur stammkneipe erklärt. dann waren wir des öfteren in der bar cuba, die echt nett ist. ausser, dass unsere gruppe den altersdurchschnitt extrem hochgesetzt hat. ich würde sagen, die durchscnitlichen besucher sind um die 25.

lustig ist natürlich auch das crazy kanguroo (oder wie man das schreibt) dort gibt es die englische version des apre skis. das beste essen gibt es im underground. genau an der piste neben der grossen gondel.

New Year's resolutions (Part 2)

2009-01-03T01:50:11+00:00

I forgot one:

Take more advantage of Barcelona
I did not spend enough time in the Zoo and the Park or the Beach this year. And I did not use the Chiringuitos, museums or open air cinema. There is a lot of stuff to do and I don't want it to be like London where I did everything in the last two months.

New Year's resolutions

2009-01-02T09:50:21+00:00

One of the traditions of celebrating the New Year (besides getting drunk and making a fool of yourself) are of course the resolutions for the next twelve months. So here are mine:

loose weight
as a rule this always have to come first and I don't want to be the one breaking it. As I think I am eating healthy enough and I am probably not going to be able to change much of it this has to be achieved with more exercise, so more cycling and the gym. I will also reduce the amount of alcohol I consume.

use my motorcycle more
I haven't used it at all in 2008, which is a pity. Every time I do use it I get a smile on my face. It also means that it will be better maintained and keep the traffic wardens happy, which towed Cats scooter because it was not moved for eight days. It doesn't make much sense to use it in Barcelona though, so I will have to do some weekend trips.

sort out my music collection
I already started deleting all my mp3s where I don't know the origin and started ripping all my CDs again. Next step will be the organising the mp3s I got through podcasts or from mix bootlegs. And the last will be digitizing my audio tapes, which will probably take the rest of the year.

travel somewhere new
Two trips are already planned to Laax and Amsterdam, but these are old favourites and I want to see some new places. Maybe a motorcycle trip to the south of France or Italy or a city break to somewhere else in Europe.

do more programming
As with the motorcycle this always brings a smile to my face and I just don't do it enough. I have started some small projects at home now and I am trying to get more in Fedora, though my first simple package submission is going extremely slow. I also have to spend more time on Python to learn faster.

I think five resolutions are probably enough, maybe one last one: I should use this blog more often.

Sonar 2009 - krass.com

2008-12-18T16:45:28+00:00

The Sonar 2009 - krass.com pages are up. This is probably the last time I do this, as it is just too much work and nobody else is helping me with the wiki.

Sonar is doing a special offer of 125 EUR for the general pass for the three days. The normal price is 140, which is the same as last year. Maybe they realize that they can't raise it every year. Some of the parties were very empty last year.

more server tuning

2008-12-13T12:43:13+00:00

In my quest to try out new things and make my rented virtual server run a bit smoother I tried two (for me) new tools:

memcached: I never had a need to use it, because at work we just do websites which nobody looks at. We could really have used this at guideguide, where we basically used mysql to cache some often used data which didn't work too well.

Installation was very easy on CentOS and mediawiki and Django have direct support for memcached. I just had to enable it and change the code for api.bicingwatch.com to make use of the cache.

lighttpd: On the previous krass.com server, which had about ten times more memory I used two apache instances. One for the static stuff and as reverse proxy for the second one for the mod_perl server. Now I am using lighttpd for the static and reverse proxy. I am not 100% convinced by the syntax, but it is rather easy to setup and allows some refactoring of the config with include files.

So for example I have in the main config:


$HTTP["host"] == "api.bicingwatch.com" {
    server.name = "api.bicingwatch.com"
    server.document-root = "/....../bicingwatch/site_media"
    include "proxy-localhost.conf"
}

And in proxy-localhost.conf


$HTTP["url"] !~ "\.(js|css|gif|jpg|png|ico|txt|swf|html|htm)$" {
  setenv.add-response-header = ( "X-Forwarded-Host" => server.name )

  proxy.server = (
      "" => (
           ( "host" => "127.0.0.1", "port" => 8000 )
      )
  )
}

And on port 8000 is the apache and mod_python installation I had before.

Seems to work ok, so that is another thing gone from my todo list.

Paris Condal - Restaurant Libanese

2008-12-12T15:16:29+00:00

View Larger Map

Another lunchtime restaurant review. I ventured over the Gran Via again on the look out for a new restaurant choice for our lunches at work.

Paris Condal is a small restaurant with an attached snack bar. They got pictures of some food in the window, which usually puts me off, but I had a good experience in Andorra so I went in anyway. The restaurant has maybe ten tables and smoking is allowed. I don't understand why anyone would have smokers in a restaurant, but there you go. The bathrooms are dirty like a dark corner in Raval.

The lunch menu is 9.90 EUR and I had dolmades as starter, couscous as main and a cortado.

Dolmades are rice wrapped in grape leaves on a little bit of boring salad. These seem to come from a tin and were certainly neither fresh or handmade. I wonder what is the point to present something like this in a restaurant.

The couscous was nice, a mixture of minestrone and lamb stew with a bit of couscous. It was very well seasoned and not greasy. But I am not sure if I would call it a mains, in another restaurant it probably would make a very nice starter.

The cortado was good and hot, which was nice.

Overall I give this restaurant one star, because I see some potential and I would try it again.

es ist zeit meinen blog zu aktivieren

2008-12-08T11:28:32+00:00

als tekki kind müsste ich eigentlich fleissiger sein. aber nein, bloggen ist noch nicht zu meinem alltag geworden.
kurz vor weihnachten geht es noch einmal richtig rund. das schöne ist, dass ich zurzeit nur tolle auswärtstermine habe.
das vereinstreffn von zukunft digital, der innovationstag von alctal-lucent und jetzt fliege ich zur nächsten veranstaltung nach antwerpen.

ich bin noch am überlegen, zu was ich meinen blog entwickeln soll.
eher technisch oder eher privat?

System administration sucks

2008-12-07T23:41:05+00:00

This weekend I moved more websites away from my old dedicated server. The site of my girlfriend moved from mediawiki to a blogger.com account. Our family website is now a planet running on the new virtual server.

And today I moved http://krass.com/ also to the virtual server. This turned out to be a major hassle, because the mediawiki version was pretty old and the mysql server changed from 4.1 to 5.0. As usual with these things I run into charset troubles. After playing for ages with various combinations of iconv and mysqldump I gave up and put a 'SET names latin1' after the connect in the mediawiki code. This is obviously not a good solution, but I can't be bothered at the moment.

I changed the skin to keep most of the mediawiki layout to make it a bit easier with upgrades and userfriendlier for people who already know wikipedia. I will play around with it though to make it look better.

Someone from Wikia contacted me last week again and wanted to know if I wo uld be interrested in moving krass.com to Wikia. I am not at the moment, but if it turns out to be too much work in the future I might take them up on the offer.

I also have to see how the virtual server can take the load, it seems to be a bit underpowered.

Snowboarding in Andorra

2008-12-01T15:07:09+00:00

Last week Cat had the brilliant idea to go snowboarding in Andorra for the weekend. The snow conditions were just turning right and the Grand Valira snow resort was opening the lifts for the first time this year. So we booked a car, hotel and the ski passes and left for Andorra on Friday evening. To our surprise it was a very quick trip because there was not a single traffic jam.

It took us a while to find the hotel, but it was not far from the El Tarter area. We were staying at the Vall Ski. I have a system of three categories for hotels. The first one are the ones where you feel at home and the atmosphere is more like staying with friends. These are usually small or B&Bs. Another category are the ones where you feel like a king and they provide everything you need without you having to ask, these are usually very expensive. And then there is the third category which is the biggest one and also the one Vall Ski belongs to. In these you feel like being in a hospital. Everything is nice and clean, but the food is horrible and served way too early. You also have to pay extra for everything. The staff was nice though. One evening we went to the restaurant next door with horrible design and menu, which surprised us with very good food by an italien chef.

When we tried to pick up our ski passes on Saturday morning, it turned out that he booking service (from the Grand Valira website) had messed up the booking. Cat spend two hours on the phone to sort it out, but the lady in the call center in Bulgaria was friendly but not helpful. So we ended up buying another set of two day passes. We will be canceling the credit card payment and I hope they will sort it out then.

The weather on the first day was very windy going to snowstorm. Sometimes I lost all sense of speed and direction. In the afternoon it turned even worse, so we had a snack and when we were finished we had the perfect conditions for the rest of the day. Fresh snow and no queueing for the whole day.

Sunday was even better, with more sun and less wind. Overall a perfect weekend for snowboarding and I think I improved my skill a little bit.

Now I am hurting everywhere though. Before we go to Laax in January I will have to spend more time in the gym and on the bicycle to get my fitness level up.

New computer and Fedora 10

2008-11-27T20:59:38+00:00

My new computer has finally arrived and last weekend I had time to put it together. With the Fedora 10 release this week I should be having a good time now. Here is what I got:

Asus M3A32-MVP Deluxe AMD 790FX / SB600
4GB RAM
AMD Phenom X4 9350e
Sapphire Radeon HD 3870 Ultimate
2 * Western Digital Caviar WD10EADS 1TB
a couple of new Papst fans

I tried to order things which save a little bit of power and are easier to cool so I can run them quieter. I also decided on a ATI graphics card because they are releasing information about their hardware and are not stuck in the past like Nvidia.

So I cleaned my old computer case, removed the dust from the last five years which required me to take it apart and put the new stuff inside. I first tried it with my old hard disks and Fedora 9, because 10 had not arrived yet.

The computer started and everything was nice and fast and shiny. But after a few reboots the only thing I got was beeeeep - beep beep beep. After a trip on the internet I found out that I picked one of the motherboard + graphic card combinations which don't seem to work. So now I am running with a borrowed Nvidia card until I buy a new motherboard or Asus comes up with a new BIOS.

I obviously also contacted Asus and Sapphire support, but it just confirmed my opinion that this is completely pointless. Asus answer was along the lines of "Have you tried turning it off and on again?" and Sapphire did not even bother.

But I still had Fedora 10 to look forward too. And so I installed it on the new hard disks. It is pretty much the same, but maybe I am just difficult to please. Here are some short notes:

the faster boot is indeed faster, but I don't care because I don't boot that often
the flicker free boot just works if you have the right graphics card and on a full moon
NetworkManager still hates me and static addresses ...
but now system-config-network hates them too ...
and so does anaconda ...
so install with dhcp
change your /etc/sysconfig/network-scripts/ifcfg-*
chkconfig NetworkManager off
chkconfig network on
service stop NetworkManager
service start network
compiz does not work with either the Nvidia or the ATI card
I am looking forward to play with the new versions of eclipse & co

To NetworkManagers defence I must say that it is very nice on my Eee PC, I just don't see the point on a desktop / workstation. The Eee PC is still downloading with preupgrade, so lets see how that goes.

Next hardware upgrades are for the firewall, backup server and htpc, which are all from 2002. I can mostly use hardware I already have and just get new cases and fans so that they stop sounding like a fighter jets landing. And I obviously have the spare M3A32 too, so that gets a Athlon X2 and goes into the htpc. Hardware can be so much fun ...

Oh ... and I am probably the last person arriving in multi core and 64 bit country. nice.

my first python website

api.bicingwatch.com has now been up for two weeks. It is a small site with just a handful of html views and some JSON views.

I also use python now to scrape the bicing.com website and store the results in a mysql database. This does not include the data I had already collected over the last year, which I will import soon.

Today I also enabled disqus commenting on the station pages. I originally planned to write this myself, but this is way quicker and I can always change to the django commenting system later.

Overall I am very happy with python and pretty used to the syntax now. I really like the internal dicts and arrays, much better than the php version and on the same level as Perl. I also like the way errors are handled, which is always with exceptions. In Perl and PHP these are very much optional and are not used a lot.

What I don't like is the quality of some of the libraries, they clearly have to do some catching up to do with CPAN.

Paella

2008-11-10T08:24:22+00:00

This is my recipe for paella. The picture was the most recent one I made. It was not perfect because it is my largest pan and it gets a bit difficult. I used two other recipes I found on-line and combined them.

olive oil
2 chicken breasts cut in dices
2 onions diced
300 g paella rice
750 ml chicken stock
saffron
handful frozen peas
1/2 green pepper
1/2 red pepper
mixed seafood: squid, prawns, octopus, mussels, shrimps, fish
parsley
dry white wine
lemon

Heat a paella or other big flat pan. Add olive oil and fry chicken for 2-3 minutes. Push to the side of the pan, add onions and fry until golden. Season with salt and pepper, but not too much as the stock is probably seasoned too.

Push everything to the side and put rice in the middle and coat it with olive oil until all of the rice is coated. Add most of the chicken stock, mix everything and cook for 10 minutes. Add vegetables and seafood and mix again. Crush the saffron and add it to the remaining stock, this also goes into the pan. Leave to simmer and add wine and water if it gets to dry. Serve with lemons slices and parsley on top.

The whole thing takes maybe half an hour, but you have to make sure that the rice does not burn or get too soggy.

If you want to go fancy you can fry some chicken legs and fresh prawns or crayfish and put them on top at the end.

A clean desk is the sign of a sick mind!

My current home office setup. The newest addition is the Samsung 245b 24" 1920x1200 TFT display. It is probably not the best one around, but is pretty good for the stuff which I do, which is mostly programming.

The main computer is an old Athlon XP 2400. I am currently waiting for replacement parts. I brought most of the stuff with me from London, which means it is from 2003 or older. At the moment the machine is running Fedora 9, but will be upgraded to Fedora 10 once it is out and the parts arrive. I think the Natural Ergonomic Keyboard 4000 is the only Microsoft product I use. It is the UK version, because I can't get used to the local versions. The mouse is a Logitech G9, just upgraded from a G5. I am not sure about the G9 just yet, the previous mouse somehow feels better in my hand.

I also got two old Dell Dimension XPS B600r. One of them is used as firewall and the other one as backup server. You can see in the picture that the backup server has a front mounted fan, otherwise the three disks stop working. Both of these computers run CentOS 5.

The computers and router are protected by APC UPS, because we have a lot of power problems here in Barcelona. In the cable jungle next to them is also the ADSL router, a KVM switch and a network switch.

Behind the monitor is also an old scanner to scan old photos and just off the picture to the right is a HP OfficeJet scanner/fax/printer combo.

The Sony TC-KA6ES tape deck is currently broken and I am trying to fix it. While this is not working I am using the Technics tape deck, the amplifier and the two JBL Control Ones to digitize my tapes with the tape recording software I am currently writing in python.

The free world has a new leader (elect)

2008-11-05T09:59:57+00:00

I am glad about the result and this shows that the USA can be a leader in democracy. My guess is that will take a long time until we see a president in a European country who is not white.

The news also speak about the amazing high turnout in this election. This might be high for the US, but does not seem so high for the rest of the world.

I also wonder what this election will change. I would love to see Americans loose some of their security paranoia and open up again.

La Generalitat estudia obligar a los usuarios del Bicing a llevar casco | El Periódico de Catalunya | Barcelona

2008-11-04T17:50:00+00:00

La Generalitat estudia obligar a los usuarios del Bicing a llevar casco | El Periódico de Catalunya | Barcelona: "El conseller de Interior, Joan Saura, ha manifestado hoy que en 'estos momentos' el Govern mantiene conversaciones con el Ayuntamiento de Barcelona para hacer balance del servicio del Bicing, y 'considerar la posibilidad' de obligar a los usuarios a llevar casco." -- That should put a stop at the problem of too many users at least.

tapetransfer

2008-10-31T23:19:09+00:00

Even though my good tape decks are broken at the moment I have started on the software to transfer my techno and house mix tapes to the computer.

I have written the software before in C++. It basically waits for a sound on the input and then writes the music to a file until it notices a long quiet section at the end of the tape and stops writing. The software was using threads and used the lame lib to do on the fly mp3 encoding, to make it even quicker to digitize tape. It also notified the user of any buffer underflows and clipped samples.

This software is more than five years old now and all the libraries have changed and I can't be bothered to fix it all.

As I want to learn python anyway I decided to rewrite it in python and see how good I can make it.

Documentation for the (multiple) alsa bindings for python is pretty bad, so I googled around and found kissrec , which is a very simple command line audio recorder with a timer and VU meter. It is GPL, so I have started with that, but I probably rewrite the whole thing to make it (in my eyes) nicer code.

You can find the whole thing at http://tapetransfer.googlecode.com/ , but please don't look to closely - it is rather ugly at the moment.

Everything breaks

2008-10-22T23:07:51+00:00

First my nice 32" LCD TV broke, which is annoying. But the TV is easily replaceable, it just takes some money. At the moment I am just using an old 21" CRT TV monitor instead, because it is no good to work on any more.

But now my beloved Sony TC-KA6ES tape deck broke. It was the best tape deck Sony ever produced. A three motor, three head
and Dolby B/C/S monster with manual tape calibration and a weight of half a ton.

I haven't used it for at least two years and this is probably the reason why it broke. Our flat here in sunny Spain gets pretty warm in the summer and it is also a very dusty city. This week I wanted to use it again, because I am working on a little python software to help me to transfer my many tapes to the computer. But now all I have left is a rubbish Technics deck.

I could try to find another good tape deck on ebay, which would set me back 100 to 350 Euro, depending on the deck. I also checked what new decks are available, but all of those are on the cheap end. I am very much in vintage territory now. I realized of course that tapes are not commonplace any more, but they vanished from the high end since five years or so now.

The other option is to find someone to fix the Sony, because it is probably just some rubber band or a dirty part. Fast forward and rewind still works and all the motors seem to work. But while repair shops like this are pretty common in Germany and London, they are difficult to find here. I might also try to fix it myself, as I can't break it much more than it already is.

I finish this post with a picture of my also lovely and broken Sony TC-C5. This one is a very rare five tape auto reverse changer. The tapes are on a carousel. I used it a lot in my time in university to record long techno and house mix shows on the Stuttgart radio. Depending on the tapes it gave me five to ten hours of music. It probably has a similar problem as the TC-KA6ES.

eee pc 901

2008-10-11T10:52:01+00:00

I progressed a step further in my quest to upgrade my computer systems at home from the outdated and unusable ones I am have at the moment. My workstation is way to slow and has a broken CRT and I have nothing portable at all.

Thursday before the phpconference I bought a Eee PC 901 (Linux version of course). As I am planning to get a proper desktop computer with a big screen for my home desk, I just needed something to take to conferences, on trips and maybe sometimes into town. I also use it at home to browse the web, when I don't want to sit on my desk.

I am used the preinstalled Linux version for a week, which is some kind of Debian based distribution. It comes with all the office and internet applications you usually need. Skype is included for example, which works with the build-in webcam. I enabled the xterm and installed emacs, eclipse and Django, which all worked pretty good.

As I am more used to Fedora and because I want a proper Linux distribution, I installed Fedora 9 though. It was a bit of a hassle to install from an USB memory stick, but worked in the end. fedoraforum has all the information about ethernet and wireless drivers. Everything else works pretty much out of the box. I used LVM to give me one big partition over both SSDs.

I probably will also upgrade to 2GB RAM, as swap is not really an option with the SSDs and eclipse or games need more memory than the stock 1GB. The CPU is pretty quick too, but that might just be compared to my other computers, where the newest is from 2002.

The worst bit is the keyboard. I don't mind it being small, but the layout is different from all other keyboards I have. The key which is usually left of the "1" is above it, to the right of the "ESC" and the "\" left of the "Z" is gone too, it is mapped with the "Fn" key onto the "Z". Having a Spanish keyboard and using GB mapping makes it not better.

So the summary so far:

Good:

cheap (350 EUR)
small and light
runs Fedora well
fast
long battery life, cool and quite
good screen
lots of ports
graphics chip supports compiz desktop effects

Bad:

keyboard
some things don't work in Fedora: multitouch touchpad
webcam could be better

comparing class syntax in C++, Java, PHP, Perl and Python

2008-10-08T13:23:23+00:00

As I recently started learning Python one of the things I noticed which I didn't like is the class syntax. So I wrote some minimal hello world programs in the languages I recently used to show the difference:

C++ hello.cc

#include <iostream>

class Hello {

private: char *value;

public: Hello(char *newvalue) {
value = newvalue;
}

public: void hello() {
std::cout << this->value;
}
};

int main() {
Hello hello("hello\n");
hello.hello();
}

I like the C++ syntax, it is the language which introduced me to OOP and it it clearly states what bits are what without too wordy syntax.

Java: hello.java

class Hello {
private String value;

public Hello (String newvalue) {
 this.value = newvalue;
}

public void hello(){
 System.out.println(this.value);
}
}

class main {
public static void main(String args[]){
 Hello hello = new Hello ("hello");
 hello.hello ();
}
}

Also very nice, a bit clearer than C++.

PHP: hello.php

<?php

class Hello {
private $value;

function __construct($newvalue) {
$this->value = $newvalue;
}

function hello() {
echo $this->value;
}
}

$hello = new Hello("hello\n");
$hello->hello();

From the dynamic languages this one is the clearest. Except of the __construct() constructor, where I prefer the ClassName() syntax (which still works in PHP5)

Perl: hello.pl

package Hello;

sub new {
my ($class,$newvalue) = @_;
bless { newvalue => $newvalue }, $class;
}

sub hello {
my $this = shift;
print $this->{newvalue};
}

package main;

$main::hello = new Hello("hello\n");
$main::hello->hello();

I always hated objects (and functions) in Perl, there is no parameter syntax for functions or methods. Most of it is not enforced and you can use functions in objects in thousands different ways.

Python: hello.py

class Hello:
_value = ""

def __init__(self,newvalue):
    self._value = newvalue

def hello(self):
    print self._value;


hello = Hello("hello")
hello.hello()

A lot clearer than Perl, but also a lot of convention instead of forced syntax. I got used to the indention by now. But I hate that I have to specify "self" as the first parameters, the __init__ syntax and the underscore prefixing of private or protected variables. At least it has proper function parameters.

phpconference.es

2008-09-27T21:44:56+00:00

I just returned from the Barcelona phpconference.es . It was a small on day conference, with just a few talks and not many big names. It was also really cheap at 20€. The organization was very good, especially for Spain. It was held at citilab in Cornellà Centre, which is at the very end of one of the metro lines. There were two rooms with parallel talks. The talks were all in english, which was a change from the last PHP conference. Wifi was available everywhere and there were free drinks and food.

In the morning I got hassled a bit by companies looking for developers, though nothing which convinced me to quit my job yet. I am glad that there are companies like this available in Barcelona though, as they seem to be interested in improving the communitiy through supporting events like this instead of seeing PHP or open source just as the “free beer” option.

I enjoyed the talk about PEAR and the one about xdebug. But none of the talks was really advanced and each one was more or less just an introduction to the topic.

One thing I noticed was the number of netbooks in use by the attendees. I would say the distribution was 30% netbooks, 40% mac and 30% for the rest. I just bought a Asus Eee PC, which is my first portable computer – but more about this another time.

Overall I must say that I am probably not a conference person. I enjoy the talks, but I am not so much av crowd person and probably could get the same information spending a day in front of firefox and youtube. But I will give it a another try next time.

Staying with Linux

2008-09-22T15:31:02+00:00

Recently I was affected by the Steve Job Reality Distortion Field. After watching the demonstration of the iPhone developer kit and the iPhone in general I wanted one too.

I thought I get myself a nice Apple Power Book or maybe an Air plus the iPhone and start developing. As it is also very much UNIX based I could still go to the command line if I want too and most of the tools I use every day are available on Max OS X and work very well.

My girlfriend has been using her PowerBook Titanium since 2002 and it still works well. She now also got the iPhone, which is the best phone you can buy at the moment. For someone who just wants to use computers, these are perfect.

But after seeing the problems software developers have with the AppStore and the sharing of information about iPhone development, I decided that this whole closed source thing is not for me.

I have been using Linux since my Amiga days and Red Hat Linux since 3.0.3 and I just can't imagening using software which doesn't have the source code available for me to learn and thinker with. Most people now will say that you probably are not going to this, but it is not true for me. I fixed, patched and changed Apache, Rhythmbox, PHP and Perl. I build my own RPMs for the changed versions to keep my system clean and I want to have this option in the future.

But it is not only the source. It is also the community and things like open bugtrackers. If I report a bug with some Apple or Microsoft product there is no way of knowing if this was reported before or if someone has a fix already. This just happened to me again with a USB mouse problem on Fedora, I just hat a look at bugzilla and there was already a solution which I was able to apply before the fix goes into the updates.

I still need to upgrade my computer though. My Athon XP 2400 (IIRC) just doesn't do the trick anymore. I also want to switch to an ATI graphics card to use open source drivers. So I decided to spend 1000€ on an upgrade to the machine, which probably consists of:

24" TFT monitor
some AMD four core CPU which doesn't use too much power
a passive cooled ATI card
4GB of memory
ASUS motherboard
two 1T hard disks for RAID1

all running the Fedora of course.

I might also get an OpenMoko phone at some point, but I am not really a phone user so it would be just a toy.

The only close source products will be my iPod Classic and iPod shuffle. But they are well supported now in gtkpod and Rhythmbox.

M_NUS @ BAM

2008-09-21T18:20:21+00:00

Went to see Magda, Gaiser and Richie Hawtin at the Red Bull Music Academy M_NUS @ BAM.

It started at midnight, which is a more civilised time than the usual 3:00 we get here in Barcelona.

Magda was very good, Gaiser was ok and Hawtin had his good moments. I think Hawtin now has the same problem as Sven Vaeth, he is just too popular and his productions and studio mix sessions are way better than his live sets. It is a pity, because I remember a lot of good parties with him a few years ago.

The visuals were also especially good, I have to find out who created them. Also very minimal, abstract and like a good screensaver. It wasn't a projection, but a enormous LED display wall with one part below the DJ desk.

Very good times, can we have more of this please?

moving wikicalendar

2008-09-13T20:29:18+00:00

I haven't updated it for ages. To prepare for some small changes I moved it to google code. This also gives me subversion, which takes another bit of work of me.

The sandbox on krass.com will still serve as a testing area.

learning something new

2008-09-13T20:26:02+00:00

I decided that it is about time to learn something new. For some reason I decided on python and django.

It might have something to do with the google app engine and because fedora uses a lot of python.

I made up a small project, which is easy to start, but can grow into something bigger later.

At my day job I use mainly php, including the cakephp framework. One thing which I am always missing is a proper ORM. I used to do a lot of perl coding and we developed our own ORM, which was very similar to Class::DBI.

So I am quite happy that django comes with a nice ORM. I also like the views and template language so far. The only thing a bit annoying is the url setup and the specifying the locations of the templates. It would be nice if there was a nice default. There might even be one and I haven't found it yet.
