Comment: power fail? (Score 2) 112

by rsmith (#41078867) Attached to: Video Purports To Show Successful Hover Bike Test Flights

The problem with all these powered lift gizmos (like the Williams X-jet and the Hiller VZ-1) is that you tend to fall out ouf the sky when your engine fails... The Hiller VZ-1 which is also a ducted fan used *two* 30 kW engines, but barely flew out of the ground effect and was limited in speed. More powerful versions had other control problems.

qubezz (520511) writes "iPhone4S owners attempting to use the Siri voice recognition feature were greeted with widespread network outage messages Thursday starting around 11am PST, reports Venture Beat and others. Comments started coming in from the twitter-verse of the outage, and Apple hasn't yet made a statement about the cause.
Siri still provided humor after service was restored: "I asked her, "Siri, where you been all day?" Her response? A number of day spas and hair salons""

+ - Deterministic Multithreading Solves Race Condition->

Submitted by
bill_mcgonigle writes "Researchers at Columbia Engineering School have developed PEREGRINE, a system that promises to improve the reliability and security of multi-threaded programs by addressing what they claim is the root cause of data race conditions in multi-threaded programs: non-determinism. Peregrine works with existing languages and "can make threads deterministic in an efficient and stable way. Peregrine can compute a plan for allowing when and where a thread can 'change lanes' and can then place barriers between the lanes, allowing threads to change lanes only at fixed locations, following a fixed order. This prevents the random collisions that can occur in a nondeterministic system.""

Submitted by Trailrunner7
Trailrunner7 (1100399) writes "A certificate authority in Malaysia has had to revoke 22 certificates it issued with weak keys and missing extensions. The problem has prompted Mozilla to revoke trust in the intermediate certificate authority from Digicert Sdn. Bhd.

A statement from Entrust, which issued the intermediate certificate to Digicert, says that there is no evidence that the CA has been compromised. However, the problem is serious enough that Mozilla moved quickly with its decision to remove the Digicert CA from its list of trusted roots. The Digicert CA in Malaysia is not affiliated with DigiCert, the U.S.-based certificate authority.

Mozilla didn't specify a date for revoking the certificate, but Entrust said it would do so by Nov. 8."

Submitted by
coondoggie writes "While conventional wisdom says virtualized environments and public clouds create massive security headaches, the godfather of Xen, the open source hypervisor, says virtualization actually holds a key to better security. Isolation — the ability to restrict what computing goes on in a given context — is a fundamental characteristic of virtualization that can be exploited to improve trustworthiness of processes on a physical system even if other processes have been compromised, says Simon Crosby, a creator of Xen and a founder of startup Bromium, which is looking to use Xen features to boost security."

Swapnil: Linux is today dominating the world. It's everywhere, except for the desktop. Why is Linux still struggling in the Desktop market?
Linus: I think, the big reason is just desktop is the hardest market to enter. It's partly because of technical reasons. Desktops are different from pretty much every other market in that they do many different things. When you do a cellphone or tablet ... [he points at my tablet thinking it was an iPad. I told him it was not the iPad it's Android. He said that's an Android that he didn't even recognize and I told him it was the Samsung Galaxy Tab. He said "Oh my wife actually wants that for Christmas."]

When we look at cell phones or tablets there is usually a fairly limited usage case. You may have thousands of applications, but you don't, for example, usually connect this thing to hundreds of different devices. I don't think you can. With desktop, usage is completely different. You have to support every different printer that you can go to store and buy."

Same CEO once called US college grads 'unemployable.' Seems he's changed his tune."
