This is exactly the point. 2.6 is bleeding edge, it is not for production servers. You don't get it if you run something as critical as a router on Linux. Juniper chose BSD for JuneOS for a reason.

Volume Shadow Copy For Linux? 300

This post raises a good point. Is there anything out there that Linux has to compete with Volume Shadow Copy on Windows? Seems like Linux is lacking a very basic functionality

Linux usage among developers is on the rise, at the expense of Windows, an MySQL has pulled significantly ahead of Oracle by a factor of 3-to-2, as the database of choice among Eclipse developers. ''The data demonstrate that fears surrounding Oracle's control over MySQL have not resulted in lower use of MySQL in favor of an alternative open source database,' Rodrigues writes."

Submission + - Researchers create Social Engineering IRC Bot (irc-junkie.org)

An anonymous reader writes: Researchers of the Vienna University of Technology developed an IRC bot that acts as a "Man in the middle" between two unsuspecting users, modifies URLs passed between them and also is capable of steering the direction the conversation goes. Not only this works surprisingly well on IRC — 76,1% click rate at maximum — also 4 out of 10 persons clicked on links on Facebook Chat after complete strangers befriended them. This would have worked even better if the bot were to clone existing friends profiles and submitting friend requests from those, say researchers.

Submission + - The Beginnings of Encrypted Computing on the Cloud (technologyreview.com)

With cloud computing on the rise, this may be the holy grail of keeping private data private on the cloud. It's called Fully Homomorphic Encryption and if you've got the computer science/mathematics chops you can read the PDF thesis here. After reworking it and simplifying it, researchers have moved it away from being true fully homomorphic encryption but it is now a little closer to being ready for cloud usage. The problem is that the more operations performed on your encrypted data, the more likely it has become 'dirty' or corrupted. To combat this, Gentry developed a way to periodically clean the data by making it self correcting. The article notes that although this isn't prepared for usage in reliable systems, it is a quick jump to implementation in just one year after the paper was published — earlier encryption papers would take as much as half a decade until they were implemented at all.
