In this PDF file I found the following table (see original screen-shot):
|Creation of qualified certs*: suitable til end of 2009||Creation of qualified certs**: suitable til end of 2010||suitable til end of 2010||suitable til end of 2015||suitable til end of 2016|
|SHA-1||SHA-1||RIPEMD-160||SHA-224 (SHA-1, RIPEMD-160)***||SHA-256, SHA-384, SHA-512|
So I hope there is anybody out there that has started to crack SHA-1 to get finished this year :P
(maybe it’s the recounter’s turn!?^^)
Yesterday, while waiting in a traffic jam, I implemented a small game. I read about this game in a book and to not get too annoyed about the waiting time I opened the lid of my laptop and wrote this game. This morning I completed it with some usual stuff to increase the usability..
It’s written in C++ and you can play against the CPU. There is a strategy that makes you win in almost every case! This game is a classic in game theory, but if I provide you with it’s original name it’ll too easy for you to solve the problem with help from Wikipedia or something like that. So just try it on you own ;)
The aim of the game is to clear all the stacks that are filled with
o ‘s. The stacks may look like this:
Now it is your turn to choose one of these stacks and remove some or all
o’s of it. Notice that you have to remove at least one of them and you can only remove
o’s from one single stack!
After your turn, the artificial intelligence will do the same. Afterwards it’s again your turn, until all stacks are cleared. Winner is the one who cleared the last stack, so try to get the last
Here is the download.
You can choose the number of stacks and the maximum number of
o’s a stack can carry:
If anybody knows the strategy, feel free to tell me!
Actually I revived my Creative Zen and had some trouble with that crazy media stuff..
Ok, every body who knows me knows that I hate that media fuss, to many functions that nobody needs, and to many failures on important stuff. How to mount an MTP-fs I explained in a previous posting, here it is in a nutshell:
With mtpfs version 0.9 and libmtp8 from sid I just experienced segfaults reported by dmesg, but the versions from squeeze just work fine. Of course it is interesting that I’m not able to overwrite existing files:
Curious, but the workaround should be clear ;)
Last but not least I can show you how to play a YouTube video on this device. The easiest way is to install the Firefox extension downloadhelper, so you can download the song as a
.flv file. The usual player don’t know what to do with
.flv , and of course mine doesn’t, so convert it with mencoder. Here is an example:
The audio file doesn’t have meta data yet, so my Zen can’t find a name for it (don’t know why they didn’t implement a fallback to name it by it’s filename). To edit the meta tags you can use common tools like amarok or XMMS, I used easytag.
So you see, with a little work everything will be fine!
To make it work on my Iceweasel 3.5.11 I had to change the
em:minVersion in the
install.rdf of the
.xpi archive. It’s just for noticing, I don’t provide this changed version because you should not download such things from sites like mine ;)
You should also take a look at F.A.T., they often have smart projects!
When I signed in this morning Micha greets me with his status of eliminating the first pot of coffee. Very interesting… So we decided to start twittering ;)
I already registered an account about ten months ago, just to see how it works, but now I’ll try to show some activity and tweet a lot of boring things..
First of all I developed a little script that tweets my messaged via curl:
Just call it with your message, it will ask for a passphrase to your account.. Just download it and use it like
./tweet.sh yeah it works .
And of course I’ve written a script that dumps all news to my console. To parse the XML I’m using Perl:
A little bit more code, but easy to use! Just download and run it with
./twitstat.pl [MAX_NUMBER_OF_TWEETS] . (You may need some additional Perl libs)
So let’s see how long I keep going on.. You can follow me at http://twitter.com/binfalse
