grep -n -A 10 "FIXME avoid" xmlparse.c

/* FIXME avoid integer overflow */
buffer = buffer == 0 ? malloc(len * 2) : realloc(buffer, len * 2);
if (!buffer) {
errorCode = XML_ERROR_NO_MEMORY;

return 0;
}

}
memcpy(buffer, end, nLeftOver);

/* FIXME avoid integer overflow */
int neededSize = len + (bufferEnd - bufferPtr);

bufferEnd = buffer + (bufferEnd - bufferPtr);
bufferPtr = buffer;

else {
char *newBuf;
int bufferSize = bufferLim - bufferPtr;
if (bufferSize == 0)

Obviously the guy who wrote this has humor.

Happy Xmas

Hakin9 IRC channel

blog@ngolde.de (Nico Golde) — Fri, 15 Sep 2006 15:33:50 +0200

Today I got a mail by hakin9. I don't really think the magazine is cool but I also don't think it totally sucks.
But I was wrong they do
The mail pointed the reader to their cool new IRC hakin9 user channel so I decided to connect, maybe its funny.
...
/join #hakin9 (sorry folks the rest is in german, maybe babelfish does a fairly good translation)

A word on work

blog@ngolde.de (Nico Golde) — Mon, 14 Aug 2006 15:26:19 +0200

We all love (or not) to hold down a job. But today I found a really nice signature which I don't want to keep back from you:

one cigarette costs 2 minutes of your life.
one bottle of beer costs 4 minutes of your life.
one working day costs 8 hours of your life.

I don't know the original author of it

Tools hidden track

blog@ngolde.de (Nico Golde) — Fri, 14 Jul 2006 15:49:42 +0200

Today someone told me (maybe its old news) that one of my favorite music bands Tool have a very special hidden track on their latest album 10000 days.

If you play the song wings for marie (part 1) right behind the song virginiti and underlay the song 10000 days (part2)
you will hear a completely new song.

That's really amazing, try it out.

What a fcking day

I can not commit to the cvs repos at university to submit my work on the webserver cause there is no free space left there:
cvs log: Logging .
cvs log: failed to create lock directory for `/home/ni/ni/lehre/cvs/unix/g102/Blatt5' (/home/ni/ni/lehre/cvs/unix/g102/Blatt5/#cvs.lock): No space left on device
cvs log: failed to obtain dir lock in repository `/home/ni/ni/lehre/cvs/unix/g102/Blatt5'
cvs [log aborted]: read lock failed - giving up

I have one idiot in my working group who is consequently destroying our work every day, today I found this in the source code:

Der betreffende Code sieht so aus:
case 'a': aport=atoi(optarg);
checkAdmin(int a); <===== LOOK AT THIS
break;

and

#ifdef _DIRENT_HAVE_D_TYPE
switch(fddir->d_type){
case DT_REG: printf("Normal Datei\n");
break;
case DT_DIR: printf("Verzeichnis \n");
break;
}

As far as I know the second code ist platform AND filesystem depended. The guy don't know stat so I think its just bad copy&paste.
Lateley his plan was to work on the authentication of a admin port and he told us that he did some research and found some
methods of authentication, biometrics, fingerprint and some other weird stuff.
But the best thing with this code is that he tried to implement parts which we had already implemented cause
he is not able to read our code.

If university tought me one thing until now its: NEVER OPEN A WORKGROUP WITH PEOPLE YOU DON'T KNOW.

Oh and I had lots of fun with learning 8 hours for theoretical computer science test (one week left).

keyboard vs. shoes

blog@ngolde.de (Nico Golde) — Mon, 26 Jun 2006 20:51:16 +0200

Today I tried to find a new keyboard and noticed that all the modern keyboards are really big crap. There are different possibilities why they are.
Here are my main reasons:
- nearly all have additional keys to launch programs (hey if you are not able to launch a program by typing its name use your mouse)
- the keystroke sucks on most of them (bless you if you have one of these old IBM keyboards with USB adapter)
- they have keys at places your old hasn't.

This was the first try ever for me buying a keyboard (in the past I always got one from fnord) and its really the same procedure when
buying shoes. The only difference is that you will not wear them around your shoes but you will wear them under your hand.
What the ductility and the size of a shoe is, is the keystroke when looking at keyboards. But not only the technical aspects are important, also
the optical aspects are. Shoes have to look nice and also your keyboard should, cause you use it every day.

So where is IBM today, producing good old ~10kg keyboards with USB adapters?
The only reason why I bought a new keyboard and not just a PS2==>USB adapter is that at my local hardware dealer this would be as cheap as a new keyboard.

And here is my new one, a Cherry cymotion expert

Thanks AK for 1337-ing me

At the moment I receive many messages which forward the link http://www.svenswmwette.com to me.
Maybe there are people who are so dumb that they share a picture of their naked girlfriend with you but this site is only referencing to http://layer-ads.de which is a provider for ads which will be shown even with a normal pop-up blocker.
The owner of Svenswmwette will receive 3 € for 1000 clicks.

Ah and btw running over a football field naked in Germany will get you in prison.
So go to your local edonkey network and get real pr0n there

nothing blogworthy

blog@ngolde.de (Nico Golde) — Thu, 20 Apr 2006 18:02:47 +0200

Sorry for blogging downtime, I am pretty busy with organizing stuff for the next term at TU.
I will blog more frequent soon. This term I am participating in a special UNIX training which includes traditional C-programming (at the moment it seems that the final works will be a small shell and a webserver), shell scripting, UNIX history etc. Maybe there is some interesting stuff included which is blogworthy

Wallpaper

blog@ngolde.de (Nico Golde) — Sat, 25 Mar 2006 16:35:38 +0100

Since I had ~62000 page (with google bots etc.) impressions in the last time for one image located in my image directory I think there are alot of people who like this wallpaper. I am not using it anymore but since it seems to be popular I will give it to you too. I am not the author and I have no clue where it came from. Blame me if you are the author.

Computers in pieces

blog@ngolde.de (Nico Golde) — Mon, 20 Feb 2006 20:56:01 +0100

Yesterday I lost one of my servers at home because a RAM component burned down and crahsed the mainboard so I need a new one.

Does someone know a good shop (online would be great) to buy second-hand computers (not ebay)?
