Submission + - Stratum 1 ntp server myth

Submitted by ls671 on Saturday October 06, 2007 @03:40AM

ls671 writes: There is a myth that prevails in the ntp community; it is better to connect to low stratum (e.g. stratum 1) servers in order to get more precise time. This is false quite often. It is explained here along with examples of poorly configured ntp servers.

Submission + - Unpatched QuickTime-to-Firefox flaw dings IE too (zdnet.com)

Submitted by SlashNot on Saturday September 15, 2007 @04:46AM

SlashNot writes: Security researcher Aviv Raff has found a way to use the one-year-old (and still unpatched) QuickTime vulnerability to automate XAS (cross application scripting) attacks against users of Microsoft's Internet Explorer. To demonstrate the attack scenario, Raff embedded a rigged QuickTime file on Google's BlogSpot to force a Skype shutdown if an IE user is tricked into visiting that Web page. Any limited Web environment that allows embedded QuickTime files can be used to host an attack against IE, Raff said.

Max Fomitchev writes: "Hello everyone, A while back I have formulated a hypothesis and conducted a small-scale study showing that the ratio of unique visitors to unique IPs could be as low as 1:10: http://www.cse.psu.edu/~mif10/IEEE-Traffic_Study.p df In other words judging by IPs there appears to be a lot more unique visitors than there is. The study confirms my hypothesis. Academic skeptics, however, argue that my data was not general enough, so I must conduct another study. Therefore I call for participation among Slahdot folks. I think this is an interesting topic for everyonw to get to the bottom of. If you have a website, which has a login page and would not mind participating — I would VERY MUCH like to hear from you. What I need to collect is a log of IPs and user IDs, which after analysis would reveal how many distinct IPs correspond to a single user in a given period of time. Alternatively, if you have a web traffic logs that you would not mind sharing for analysis (with strict keeping of user privacy) I would VERY MUCH like to hear from you. This study is rather important and I count on your cooperation. Max Fomitchev Assistant Professor of Computer Science & Engineering Pennsylvania State University"

Submission + - Replacing atime With relatime in the Kernel (kerneltrap.org)

eldavojohn writes: "Our friend Jeremy at the Kernal Trap has has dug up some interesting criticism of atime from god himself, Linus Torvalds. As Linus submitted patches to improve relatime he noted: "I cannot over-emphasize how much of a deal it is in practice. Atime updates are by far the biggest IO performance deficiency that Linux has today. Getting rid of atime updates would give us more everyday Linux performance than all the pagecache speedups of the past 10 years, _combined_." And later severely beat atime about the head with a pointed stick: "It's also perhaps the most stupid Unix design idea of all times. Unix is really nice and well done, but think about this a bit: 'For every file that is read from the disk, lets do a ... write to the disk! And, for every file that is already cached and which we read from the cache ... do a write to the disk!" Well, I guess I can expect my Linux machine to become a little bit faster!"

Submission + - Removable drive Filesystem for Linux and Windows

Submitted by kishore.avv on Thursday May 10, 2007 @07:19AM

kishore.avv writes: Wonder which filesystem /.'ers use for their removable drives (with large numbers of small files), for windows and linux. NTFS is unstable on linux and YAReG/etc. are unstable for large number of files. Is there any really good journaling file system providing driver level (even user level is tolerable) but stable, operation for both operating systems? Googling does not help very much here.
