Het is zover! Geïnspireerd door Google die al geruime tijd haar medewerkers 20% van de werktijd ‘cadeau’ geeft om te experimenteren gaat Burobjorn vanaf nu op vrijdag lekker experimenteren, werken aan eigen projecten en spelen met nieuwe concepten. Bij Google heeft dat onder andere geleid tot de indrukwekkend browser gebaseerde applicatie Gmail. Wie weet wat er bij Burobjorn uitkomt? Op maandag tot en met donderdag staat Burobjorn zoals altijd voor je gereed, maar de vrijdag is dus voortaan voor eigen werk!

Thanks to this post on Tech recipes I can easily replace DOS/Windows line endings in files:

To remove the ^M characters at the end of all lines in vi, use:

:%s/^V^M//g

The ^v is a CONTROL-V character and ^m is a CONTROL-M. When you type this, it will look like this:

:%s/^M//g

In UNIX, you can escape a control character by preceeding it with a CONTROL-V. The :%s is a basic search and replace command in vi. It tells vi to replace the regular expression between the first and second slashes (^M) with the text between the second and third slashes (nothing in this case). The g at the end directs vi to search and replace globally (all occurrences).

If you’re like me, you might have a lot of ssh keys installed and this might prevent you from logging into servers with the following message as a result:

“Too many authentication failures”.

As far as I understood this happens due to SSH trying each key on the client for logging and failing due to hitting the serverMaxAuthTries in the SSH server configuration. I use the following quick fix to work around this, by forcing SSH to use a password instead of a public key:

ssh -o PubkeyAuthentication=no username@hostname.com

I’m pretty sure there has to be a better, more durable solution for this issue, but the above fix allows you to at least gain access to your server again. Btw I use this on Linux (Ubuntu 10.04) with OpenSSH_5.3p1 Debian-3ubuntu4.

Naar aanleiding van mijn deelname aan het door Xpert CMKB en Culturele Zondagen georganiseerde auteursrechten gesprek/debat staat er nu een interview met mij op de site van Xpert CMKB. Zie hier voor het interview: http://www.xpertcmkb.nl/?p=1618

Update: The presentation was recorded and can be found here: http://lac.linuxaudio.org/2010/recordings/day2_1645_Open_Media_Creative_Commons.ogv

I’ve just came home from my presentation at the Linux Audio Conference in Utrecht. I got the impression it went pretty good. The audience participated and people asked me some pretty interesting and hard questions. All the presentations were also streamed and I presume the video will be made available online later on.

My presentation on Creative Commons can be downloaded here: 2010-05-02-Bjorn-Wijers-Burobjorn-Linux-Audio-Conference (PDF file)

Ps: The Linux Audio Conference continues until the 4th of May. I will give another talk/workshop on Tuesday morning (4th of May) from 10:30 AM untill 12:00, in which I will look into more depth at openness (media, hardware etc) in general and not just Creative Commons.

Voor diegene die interesse hebben in cultuur en auteursrecht is er morgen een vertoning van RIP, a remix manifesto in het Louis Hartlooper Complex in Utrecht.

Na afloop is er een gesprek/discussie over auteursrecht en muziekcultuur. Hierbij zal ik Paul Keller (Creative Commons Nederland) vervangen als moderator. Verdere deelnemers aan dit gesprek zijn Pitto (DJ, winnaar Grote Prijs van Nederland in de categorie dance), Joost Gerritsen (De Gier | Stam & Advocaten) en Mirko Tobias Schaefer (faculteit Geesteswetenschappen UU). Meer info is hier te vinden: http://www.xpertcmkb.nl/?p=1527

Just saw this video by Douglas Rushkoff on what I would call ‘programming literacy’ and it made me curious about his new book Life Inc. I really like this quote from the last part of this video:

“If we don’t create a society, that at least knows there is a thing called programming, then we will end being not the programmers, but the users and worse: the used”

“If RepRap is succesfull a number of changes may well happen in society. The principal one of them will be that we have the distribution of the
manufacture of goods. At the moment economics scale it means that it is sensible for goods to be manufactured in factories and then to be shipped to the individual people who wish to have these goods using a complicated transport system. If RepRap takes off and increases its abilities by evolution to manufacture more and more products, then people having these machines in their homes will be no longer a need, or no longer such a big need for factories to make the goods they want. When they want something it will simply be a question of downloading it from the web, in the way they currently do with music, a film or anything else. That downloaded file would then allow them to manufacture whatever object is was they wanted in their own home.[...]”

Check the embedded movie below by RepRap.org from which I took this quote (starts around 5:14) by Adrian Bowyer from. The RepRap raises a lot of interesting questions, such as is personal fabrication another nail in the coffin of intellectual property? Looking forward to this publication: “The Intellectual Property Implications Of Low-Cost 3D Printing by Simon Bradshaw, Adrian Bowyer and Patrick Haufe.” which as far as I can see will be available online here, the 15th of April.

I needed files of certain size so I could test an upload threshold. I used the dd command on Ubuntu Linux to create a file of 25MB.


dd if=/dev/zero of=test-size25M.bin bs=25000000 count=1


Ik heb voor de Wordpress plugin Limit Login Attempts – ontwikkeld door Johan Eenfeldt – een Nederlandse vertaling gemaakt. Het is gebaseerd op versie 1.4.1 van de plugin. Schroom niet om contact op te nemen voor wijzigingen of op- en/of aanmerkingen op de Nederlandse vertaling.

De vertaling is hier te downloaden.

Installatie:

1. Gedownload zip bestand uitpakken.
2. Bestanden in Limit Login Attempts directory plaatsen
3. Wordpress op Nederlands als taal instellen

ps: Ik heb Johan inmiddels ook op de hoogte gesteld van de Nederlandse vertaling en ik hoop dat de vertaling zo spoedig mogelijk toegevoegd wordt aan de plugin zelf zodat je deze vertaling niet meer extra hoeft te downloaden.
