del.icio.us

I know this is like uber-old news now, but I just started playing with del.icio.us, and I’m really starting to like it. It’s a public bookmarking system with some neat features, the kewlest being that you can share your bookmarks with everyone else via a web-page interface, or an RSS feed. Bookmarks can be made via the homepage, or you can put a link in your bookmarks toolbar (IE or Mozilla) which will pop-up a little window where you can fill in the info for the given link.

Another neat feature that seems to be really popular with all of my friends is the ‘tags’ functionality where you can attach certain keywords to a bookmark, so that you can recall a group of bookmarks based on these keywords. Very useful, in my opinion, I keep a fair amount of bookmarks (not as much as my friends though, they get like 10-20 new bookmarks a day, which I have no idea how they can take in that much information), and I’ve made good use of the tags.

If you do decide to use del.icio.us, leave a comment with your del.icio.us bookmarks page :-)

Collisions for Hash Functions MD4, MD5, HAVAL-128 and RIPEMD

You’ve probably already seen this, since it’s been making it’s way around to all the blogs, but in case you haven’t, a group of Chinese researchers have demonstrated a technique to find collisions for MD4, MD5, HAVAL-128, and RIPEMD.

On a related note, Biham and Chen published a paper at the same crypto conference demonstrating a collision in SHA-0, a close cousin to the NIST standard SHA-1. Although it should be noted that as of right now the attack doesn’t look like it will be able to be extended to SHA-1.

I tested out the MD5 collisions myself on my OpenBSD box, and they seem to work! Looks like the Chinese can go collect their $10,000.00 now.

Say Hello to WordPress!

Well, it’s finally done! I’ve finally migrated myself to WordPress, and let me tell you, I couldn’t be happier! :-) I’m liking WordPress’ interface, it’s pretty clean, imports MT entries nicely, and about the only two complaints I have about it are that you have to have a MySQL backend, and that creating multiple blogs means multiple installations. However, other than that, I’m pretty pleased with what I’ve seen so far.

Most of my old blogs are still around, and still running MT, I’ll be keeping them around for historical purposes, but obviously won’t be updating them. Entries from my OpenBSD blog and my Notes have both been merged into this blog, since neither one really had enough entries to justify a separate blog.

I don’t know what I’m going to do about my Diary yet, I’ve got this love-hate relationship with it. Some days I want it around, some days I need it around, and some days I just want to burn the damn thing. If I ever get the urge (or time), I might try to migrate it over to a separate WP blog.

Sorry for the default layout, haven’t had time to fix up a new one. I’ll get to it as soon as I can.
