An Idiot's Guide to Neural Networks

If you use the 'Search' option on your browser to look for articles on Neural Networks or "Connectionism" (which is another name for the same subject), you will find a great many sites explaining what they are and how they work. Unfortunately, they all seem to be written by mathematicians, all of whom speak Double Dutch. This is fine, providing you speak fluent higher mathematics, but when I wanted to find out how they worked, I looked from a programmer's point of view. What if I really wanted to find program source code, would I find any? Here, the idiots guide to neural networks comes to aid.

Balloon

There's nothing more startling than rising from your lazy couch at evening dusk, and seeing a hot air balloon landing in the field behind your garden. This baby, marked with advertisement from a technology education center in Mechelen (100m from my work !), dumped itself in a corn meadow. 5 minutes later, the companion car arrived and the great folding could begin.
Mark the dark spot above the ballon in the picture. Even at higher resolution, I have no idea if this is a bird (maybe a bit large, no ?), a blow of hot air, or a piece of venting sail from the balloon.

Solar foil

I purchased recently some solar foil; it's the best way to observe the sun safely : ocular solar filter are just unsafe, because of the high temperatures it receives by all the concentrated sunlight in your telescope. Solar projection is rather awkward to take pictures.


Solar foil reduces the sunlight to 0.000 01 percent of its strength, which gives nice pictures like the inset here. Unfortunately the sun surface is quite boring the last days : not a single tiny sunspot in sight.

Funny things seen in source code

At the top of a particularly convoluted and otherwise completely uncommented code:


// Abandon all hope, ye who enter here.



The c2.com wiki has a page with all the funny and weird stuff that can be found in source code.

Seen on Slash

The time that I read Slashdots comments is long gone. There's just too much noise, even with a +5 filter. In the case you really want to read the best ./ comments, head over to Seen on Slash, which accumulates the most relevant comments.

The Moscow underground

The Moscow underground is renowned for its majestic splender, take a look for yourself. Check out Unrealised Moscow too, for a look on some of Stalinists' taste in architecture from the 1930s to the early 1950s. Although, ultimately, neither of these projects was realised, the plans submitted by the participants had a noticeable influence on the development of Moscow. Considered today, it is clear that the best examples of this architecture, most of which never got beyond the drawing board, are more profound and interesting than the ideological norms within the constraints of which they were devised.

TW Classic 2006

TW Classic is over, and judging by the number of visitors (over 50 000), this years edition was a great success. With bands like Simple Minds, Arsenal and Sting, the line-up surely was way better than last year.


Only two things were annoying :
- the food was way less varied than the previous years (eg no chinese stuff this time)
- the stench that surrounded the festival area was immense. Whether this was due to the large number of visitors, or to the last week's 80 000 people visiting Rock Werchter is unknown.
