New Attack on WiFi
Posted: August 28, 2009 Filed under: Uncategorized Leave a comment »Toshihiro Ohigashi of Hiroshima University and Masakatu Morii of Kobe University have developed a practical attack on WiFi connections that use WPA security with the TKIP algorithm.
While not as weak as the earlier, and now completely broken, WEP security, this attack means that WPA/TKIP can no longer be trusted to keep your network safe.
The good news is that reasonably recent WiFi access-points offer the alternative AES encryption that is not vulnerable to this attack. Avoiding this problem is as simple as logging in to the access-point’s administration page and changing the encryption setting.

Alan Kay on Smalltalk Origins
Posted: August 3, 2009 Filed under: Uncategorized | Tags: alankay, internet Leave a comment »Alan Kay responds in a discussion about the origins of the Smalltalk programming language:
This is an interesting example of an ever increasing web disease — that is: expressing mere opinions without foundations or checking. This one is easy, because there is a readily available “Early History of Smalltalk” that the ACM got me to write in 1993. So why wouldn’t people just type “history of smalltalk” into Google? (I don’t know and I haven’t been able to figure this out).
The very first hit finds this paper. (This one is not the best version of it because someone just scanned the doc I wrote to get an HTML version and left out lots of the pictures. But in looking at it, it seems to answer this question very straightforwardly — and that answer was given by “someone who was actually there” and had a hand in the invention of Smalltalk, rather than people with opinions from the side.)
What is wrong? Why is mere opinion so dominating discussions held on the easiest medium there has ever been that can provide substantiations with just a little curiosity and work? Is the world completely reverting to an oral culture of assertions held around an electronic campfire?
I’m not sure that our behaviour on the Internet is much different to what you get at the water-cooler, in the tea-room or on talk-back radio. But instant access to the facts makes it less excusable.
Anyway, if you’re a software developer, Alan Kay’s paper is a good read.
