The Null Device
2005/2/16
The SHA-1 hash function, touted for a few years as more secure than MD5, has apparently been broken. What this means is that (assuming that the details check out), for any file (such as a digital signature) with a SHA-1 checksum, an attacker can create an alternative file with the same checksum in a sufficiently short time to make it practical. Which means that, with a modern computer, script kiddies, online fraudsters and others will soon be able to create genuine-looking digital signatures on demand. (via Techdirt)
jwz on what's wrong with the idea of groupware, and how a focus on groupware (imposed from above by management) killed Netscape:
If you want to do something that's going to change the world, build software that people want to use instead of software that managers want to buy. When words like "groupware" and "enterprise" start getting tossed around, you're doing the latter. You start adding features to satisfy line-items on some checklist that was constructed by interminable committee meetings among bureaucrats, and you're coding toward an externally-dictated product specification that maybe some company will want to buy a hundred "seats" of, but that nobody will ever love. With that kind of motivation, nobody will ever find it sexy. It won't make anyone happy.
So I said, narrow the focus. Your "use case" should be, there's a 22 year old college student living in the dorms. How will this software get him laid? That got me a look like I had just sprouted a third head, but bear with me, because I think that it's not only crude but insightful. "How will this software get my users laid" should be on the minds of anyone writing social software (and these days, almost all software is social software).
