Converting a color picture to a stencil

Just strolled onto this post: “Converting a colour photo to a single layered stencil with Photoshop” (via furl.net) and I thought: you don’t need no friggin’ Photoshop to do that! Let me show you how it’s done with (free) Irfanview (Windows):

START
We start with the same picture as the Photoshop procedure above (actually I blew it up to 4x the size, double width, double height):

STEP 1: convert to grey

Barcamp Brussels: 10 days to go!

Saturday 20 May

Barcamp Brussels logo

Like M.A.R.R.S. said: “Countdown is progressive“. Ten days from now we’ll be frantically preparing the International Press Center for Barcamp Brussels. This is the progress report:

  • We have found some very helpful sponsors (including Skynet) to help us with catering and equipment.
  • Everything will be recorded and made available afterwards. Ine will be coordinating the audio/video podcast efforts.
  • We have just jumped above 40 attendees on the Barcamp attendee list. Fifty would be an even nicer number. If you still know other people that could be interested to attend, just ask them! (more details on the concept here!)

Checklist

If you want to attend, this is what you should do:

  1. add your name to the attendee list
  2. add your topic/speech/demo to the topic list
  3. prepare your topic (Powerpoint, web demo, panel discussion)
  4. show up on Saturday May 20th!

She good writer #3

She good writer
(also check She Good Writer #2)

Sarah Brown is a free-lance writer from NYC. Judging from her blog, Que Sera Sera, she’s the kind of woman you’d like to have on your team in any verbal combat. Switching back and forth between self-mockery and sarcasm with the occasional pinch of misanthropy, she transform the small bumps in her life into amusing tales of (kind of) good and (mostly) evil.

She also hosts a reading series Cringe in New York: “brave souls come forward and read aloud from their teenage diaries, journals, notes, letters, poems, abandoned rock operas, and other general representations of the crushing misery of their humiliating adolescence“.

In the next part she details her advanced seduction skills:

Originally it was just me being rude, but now that I know where it’s coming from, it’s combined with a powerful middle school urge to hide in a closet whenever I see him coming, and if I can’t, I just say the meanest thing that pops into my head. I get fucking flustered and I hate it. For some reason, he keeps talking to me, but I fear that if it ever progresses to the point where he goes for the lean in, I might end up breaking his kneecaps before I can stop myself. This makes me nervous when he tries to make small talk, and then I end up blurting out things like, “What, were you raised in an orphanage?” And I don’t say this in a playful or sarcastic way: it comes out of my mouth in this disdainful, curt tone like I am seriously insinuating that his parents gave him away when he was an infant because they didn’t want him. But oh man, apparently I do.

Database war stories: DB vs ‘square’ files

Plug and PlayI’ve been following the Database War Stories of O’Reilly Radar: how companies use text-based alternatives to classic relational database systems in order to cope with huge volumes. Check out the stories of Findory/Amazon, Google File System, Flickr and Second Life. Anyway, this seemed like a good moment to share some of my database war stories. Let me take you back to the early nineties.

1993 @ Ukkel
I arrive at Sopres, one of the larger direct marketing / database management companies in Belgium. Fresh from university (and 1 year of military service), I expect to see RDBMS everywhere and dive into SQL. Imagine my surprise when I see that, yes, there are a lot of Sybase SQLServer databases around, but the bulk of the work is done with something they call ‘square files’ (see below). They have built a whole set of tools to work with those and by using them myself, I learn to appreciate the advantanges of the system (speed, mainly) and grow a fairly accurate intuition for things like queries, indexes and outer joins.
