ssdsa··on Infinite complexity in 4096 bytes
If you are not familiar with 4k intros, you may wonder how things are organized at the executable level to achieve this kind of packing-performance. Probably the most important and essential aspect of 4k-64k intros is the compressor. Have a look here: http://code4k.blogspot.de/2010/12/crinkler-secrets-4k-intro-...
ssdsa··on Infinite complexity in 4096 bytes
For the record, the SID chip was used in Commodore 64, while Amiga had the Paula chip for sound output.
ssdsa··on Old People Icons That Don't Make Sense Anymore
Well, horsepower has absolutely something to do with horses: http://en.wikipedia.org/wiki/Horsepower "Horsepower was originally defined to compare the output of steam engines with the power of draft horses in continuous operation."
ssdsa··on The 'Flying Carpet' - The fastest way to fill a plane
That's a nice idea, but row boarding doesn't allow couples or families - obviously wanting to sit together in a "column" ("row")? eventually - to stay together during the boarding process. This could be especially difficult if there are parents with young children.
ssdsa··on The first animated graphic novel
Well, that's not actually the first... Electric Sheep Comix did this 10 years ago: http://www.electricsheepcomix.com/
ssdsa··on What happens if you shrink the Earth to the size of a tennis ball?
The "Deutsches Museum" in Munich, Germany has got a permanent outdoor exhibit exactly of this kind. Some pictures are here: http://www.deutsches-museum.de/ausstellungen/naturwissenscha... You have to walk more than 4 kilometers from the sun to the "edge" of our solar systems. It's a great thing to educate children or a school class.
ssdsa··on The Real Cost of Used Games
While we clearly see that there is a huge market for used games (see GameStop), there isn't any comparable market for used books and used furniture, at least not here in Germany. Every avid reader I know likes to read new books and cannot stand to read used books coming from some unknown pre-owner, because you never know how dirty his hands were when he was reading the book. Ever tried to sell used books on eBay? Don't bother, even if you put them up for 1 EUR starting price, you end up having more work to do (communication, check payment, shipping) than you'll earn. And don't get me started on used furniture. While new furniture can be really expensive, when you try to sell your previously expensive furniture, nobody wants to buy it.
ssdsa··on Quicksort is broken. Is it worth fixing?
A really nice essay about Quicksort and it's quirks and border cases. Worth a read!

On the other hand, when developing an application, you should think twice if you really need to write your own sorting routine. Better stick with the system library unless you have some use case that really requires your own sorting implementation.

ssdsa··on Sixty Years Old - is my future short and messy, or long and glorious?
Maybe an artificial intelligence may yield the results necessary to enable some of us to "live forever" - in whatever form that may be. However, artificial intelligence may go bad and turn against us even if that honestly wasn't our intention when creating the AI. The folks at LessWrong have some pretty good thoughts on that topic: http://wiki.lesswrong.com/wiki/Friendly_artificial_intellige...
ssdsa··on Jack Tramiel, founder of Commodore, dies at age 83
And POKE646,12 so the text color is a medium gray.
ssdsa··on Jack Tramiel, founder of Commodore, dies at age 83
No matter if it is 3583 BYTES FREE or 38911 BYTES FREE or some other number - the start-up text was an important message to all users: There's this language (BASIC) available right here at the prompt, ready for you, just type away. And there are N bytes free, available for you to do whatever you want to do.
ssdsa··on Jack Tramiel, founder of Commodore, dies at age 83
Without him, the world would be a different place. The Commodore computers inspired so many people (adults now) and made all "our" business world, start-up world and hacker world what it is now. By bringing home computers to a huge number of houses, a lot of kids got the chance to experience first-hand what it is like to be in control of a "personal" computer.

There is still a C64 scene alive! http://noname.c64.org/csdb/

ssdsa··on Wind Map
Yes, of course! The master of this technique is here: http://www.effectgames.com/demos/canvascycle/
ssdsa··on Why do we need "? extends" in Java
Wow, I'm so glad that I don't need to worry about such a mess when using duck-typing in Python.
ssdsa··on Lambda calculus with Church encoding in C
Wow, that is really impressive! Unfortunately, this means lots of work for the C preprocessor (and the C compiler, then) at compile time. But it's cool that it works this way at all.
ssdsa··on Making of Prince of Persia now available as an ebook
Thanks for the head up. I bought it right away!
ssdsa··on Show HN: CSSHumor.com
Execution is nice, but I don't get the jokes. :(
ssdsa··on A Mouse Can Infect Your Network
From the article:

"IT security admins must understand that a computer can be compromised by almost any hardware device plugged into it. Hardware is hardware -- the instructions coded into it and its firmware takes precedence over software. When we talk trust boundaries in computer security, you always have to remember the hardware boundary must be discussed and defended. If I, as the attacker, can convince a victim to plug in some sort of hardware or if I plug it in myself, then it is, for all intense purposes, game over. If I can plug something into your USB, DMA, FireWire, and now mouse port, I'll likely succeed in carrying off a malicious action."

Wow, what a lot of nonsense! Why would a hardware USB device necessarily have access over the whole computer? And the author doesn't even know that there is no different between a USB port and a mouse port ...

ssdsa··on Show HN: roll.io eats txt files and shits youtube videos. Useful?
I wonder why everyone seems to get what this does from reading the description. When I read "eat and shit", I assume that the "food" is "transformed" into ... youtube videos. So I thought this would generate new videos and upload them to youtube automatically, maybe showing the txt files as a huge StarWars scroller, or something.
ssdsa··on Drugmakers undermine medical journals and skew medical research
Are there any other non-native speakers who thought of drug lords when reading the headline?
ssdsa··on Textify: Convert images to HTML text
Sorry, but I didn't create any web interface for that back in 1997. :-) Instead, I wrote a C program to generate those HTML files. More information on that is here: http://home.wtal.de/ss/html/pnmtohtml/pnmtohtml.html - Sorry, in German. Maybe Google translate might be of some use: http://translate.google.de/translate?js=n&prev=_t&hl...
ssdsa··on Textify: Convert images to HTML text
I did something similar in 1997 (!): http://home.wtal.de/ss/html/pnmtohtml/baby_032.html What do you think?
ssdsa··on Visual6502.org - VIC-II from a Commodore 64
There are several projects tried to emulate a Commodore 64 as close to the original as possible. This includes emulating all undocumented features and quirks of the VIC-II chip that creates the video output.

This is important since many great games and demos for the C64 made heavy use of these quirks.

By using the die shot, you can reengineer all internal logic and find and understand those quirks fully.

ssdsa··on Improving CAPTCHAs with Unicode Visual Spoofing
This is just an improvement by obscurity, not a real improvement.

A dedicated CAPTCHA hacker just has to create a mapping table once, and use it in all hacking attempts. The mapping table would map all unicode "A"-lookalikes to "A", and so on.

Also, this improvement breaks when a human user tries to use copy and paste to fill the word "apple" into the field instead of typing it in.

Furthermore, aren't most CAPTCHAs broken by humans being paid for that task?

ssdsa··on Robots.txt is a suicide note
I don't really understand why they compare the Robots.txt file to a suicide note. Could anyone explain this?
ssdsa··on Any ideas how this might work?
Maybe you could try to recognize different kinds of food, but I doubt that you could measure the volume of food by just one picture. Even humans would not be able to correctly guess the calories because there is not visual difference between low-fat cheese and regular cheese, for example.

You could also devise a "pregnancy test" app - simply take a picture of the woman's face - yes, of her face ;-) - and you get the result: pregnant or not, and whether it's a boy or a girl, and the due date. Honestly, people falling for the mealsnap app would also fall for this.

ssdsa··on How publishers punish us for buying new games
Why don't you go retro, and start playing games on a Commodore 64 again? No online registration, no downloads, no patches. Simply good gameplay. No need to always have the latest hardware or software updates. Honestly, those were the days!
ssdsa··on Why Your “Collectibles” Are Worthless
When trying to sell some "Collectibles" on eBay, you can gain a lot by carefully crafting a detailed item description, with more than one photo of superb quality. Also emphasize what makes this item collectible or rare, and sprinkle in some sentences saying how desireable the item is. Finally, wait until autumn or winter, because most "Collectors" don't buy very much during the summer. That way, you may get a lot higher bids for your collectible than some other random seller who sells his items with bad or stock photos and descriptions with virtually no details.

Some time ago, I sold some old, rare computer games on eBay this way. There are several boxes of games in my attic at this time that I "collected" some years ago, and I hope to sell them for a descent price some time in the future (when I find the time to take photos and craft good item descriptions).

ssdsa··on Does anyone else hate coding on laptop?
It's annoying when the laptop keyboard lacks some keys you are used to, e.g. the Windows key or the Windows popup-menu key. You can bring up the Windows popup-menu by pressing Shift-F10, though.

Mouse vs. trackpad is an important point. In my experience, a TrackPoint is more usable than a touchpad (trackpad). So be glad when your laptop has got one.

ssdsa··on "Maybe it’s time to move on from the Commodore 64 software"
As long as there are enough C64 enthusiasts, there will always be someone who is going to port VICE (or some other C64 emulator) to a new platform, no matter what "Windowing System" that platform has got.
