MD5 collisions
Thursday, March 30th, 2006On http://www.cits.rub.de/MD5Collisions/ you can find two different postscript files with the same MD5 hash.
That’s why I wouldn’t use MD5 anymore. SHA-1 should be secure enough for now…

Mar 23 18:38:35 server kernel: sdb: Current: sense key=0x3
Mar 23 18:38:35 server kernel: ASC=0x11 ASCQ=0x0
Mar 23 18:38:35 server kernel: end_request: I/O error, dev sdb, sector 228134640
Mar 23 18:38:35 server kernel: loop7: loop_end_io_transfer err=-5 bi_rw=0x0
Mar 23 18:38:35 server kernel: EXT3-fs error (device loop7): ext3_get_inode_loc:
unable to read inode block - inode=2044226, block=4096014
There are many files that aren’t readable anymore (Input/output error). I noticed that this is not the first Maxtor harddisk I’m having problems with. I had also problems with my 40 GB Maxtor 6E040L0 and an older 6.8 GB Maxtor harddisk, which I already threw away. My other five harddisks (which are not from Maxtor) work without any problems. My conclusion: Never buy a Maxtor harddisk! Is there anyone with similar experiences? Vista erneut verschobenWednesday, March 22nd, 2006Wie heise.de mitteilt, wurde Windows Vista jetzt auf den Januar 2007 verschoben. Ursprünglich sollte der Nachfolger von Windows XP im Jahre 2002 erscheinen - und das mit mehr Features. In einem Kommentar findet sich eine nette Chronik der Ankündigungen. Ausserdem wurde wieder eine neue Lücke im Internet Explorer bekannt. Alle seit 2002 bekannten Lücken habe ich auf meiner NoIE-Seite zusammengetellt. Useful web development toolsThursday, March 9th, 2006Here are some tools that might be helpful if you’re creating websites. The first one is GNOME Colorscheme which allows you to generate a variety of colorschemes from a single starting color. Note that there are many dependencies when you’re trying to compile it from the source code. The second one is LinkChecker which allows you to check your website for broken links. I like the HTML output: linkchecker -o html http://www.example.com/ > output.html And if you don’t know the Web Developer Toolbar for Firefox yet, check it out! Quick script to count occurrences of wordsTuesday, March 7th, 2006I wanted to know how many times the words in a file appear. So I wrote a Python script that counts them. Please note that the code was written in a hurry and I know it’s possible to make it better. Here’s it: import sys
print sys.argv[1]
f = file(sys.argv[1])
buf = ''
while True:
line = f.readline()
if len(line) == 0:
break
buf += line
f.close()
buf = buf.replace('n', ' ')
buf = buf.replace('(', ' ')
buf = buf.replace(')', ' ')
arr = buf.split(' ')
dict = {}
for word in arr:
if not word in dict:
dict[word] = 0
dict[word] += 1
for i in sorted(dict.items(), lambda a, b: cmp(b[1], a[1])):
print '%s: %s' % i
