Rendering distance fields using the Go-language
Geplaatst door Reinder Nijhoff op 2 February 2010
Every two weeks, one of us gives a talk for the other employees here at Infi. The subject of these talks are mostly related to our work -something technical or about project management- but you are free to choose the subject you want.
Last monday I gave this talk (which we call the 'Infi Academy'). This was a good excuse for me to take some time and give two things a try that I've had on my wish list for a while:
1. The Go language introduced by Google last november.
2. The rendering of distance fields described by Iñigo Quílez in this article on his site.
PuTTY with Windows 7 jumplist support
Geplaatst door Daniel B. Roy op 29 January 2010
One of Windows 7's neater additions is the jumplist (my Mac Fanboy co-workers would actually call this a 'stolen UI idea'). This is a really handy thing for PuTTY, because it would allow you to start a saved session directly, without having to start PuTTY first and then double-clicking the session. You would then have a type of shortcut to saved sessions and as an added bonus save one valuable mouse-click in the process. Also, by pinning items in the jumplist, this offers a recent and favorite sessions functionality. Since PuTTY is open source, I decided to download the code and add this functionality myself. The resultant new version of PuTTY is downloadable below.

Eens in de twee weken bereidt een van onze medewerkers een praatje van ca. 45 minuten voor, over een zelf te kiezen onderwerp, bijvoorbeeld de 'uitkomst' van iemands hobbydagen. Het onderwerp mag praktisch of theoretisch van aard zijn en hoeft niet perse raakvlakken te hebben met allerdaagse werkzaamheden. Iedereen mag (en wordt aangemoedigd!) deze praatjes (te) geven, het maakt niet uit hoe lang iemand bij ons werkzaam is. Het doel is om het algemene kennisniveau te verhogen, om in aanraking te komen met materie die je niet tegenkomt in je dagelijkse google speurtochten bij het oplossen van bugs. We noemen deze reeks praatjes (met een glimlach) de Infi Academy.
Asterisk: wrong callerid when doing an attended transfer
Geplaatst door Roy de Boer op 5 December 2009
Envision the following situation:
- Alice calls Infi to speak to Charles.
- Bob at Infi answers the telephone and transfers the call to Charles.
- Charles notices the phone ringing, sees Bob's Caller ID and picks up the phone informally ('Hi Bob!'). Bob informs Charles that Alice wants to speak to him.
- Bob hangs up the telephone and Alice can speak to Charles.
Java implicit widening and narrowing conversions before autoboxing

Just for fun, and to add several extra capitals to the end of my name, I decided to take the Sun Certified Java Programmer exam recently. I used this book to prepare which gets a BIG thumbs up. If you already know how to program and want a book that covers all topics, but can also double as a general reference work, this is your best choice. Being used to the extremely low standard of most MSPress exam prep books, this was a refreshingly intelligent and complete book, with some very challenging questions. Having studied the book, the exam was a breeze.
Backup retention script
Geplaatst door Roy de Boer op 5 October 2009
Rsync (in combination with hardlinked snapshots) is a very nice way to backup linux servers. I’m not going to explain how to script things, there are already enough sites doing this, see for example this site. Because corruption and accidental file removes can occur at any time, also 1 second before the file is written to the backup, it is important to keep more than one backup. Furthermore, it can take a while before corruption is noticed: days, weeks or even months.
