Submission + - Dell is Now a Private Company Again

Gunfighter writes: StreetInsider.com reports: Dell, Inc. completed its go-private tranaction by Michael Dell, Dell’s Founder, Chairman and CEO, and Silver Lake Partners, a leading global technology investment firm. Stockholders will receive $13.75 in cash for each share of Dell common stock they hold, plus payment of a special cash dividend of $0.13 per share to stockholders of record as of the close of business on Oct. 28, 2013, for total consideration of $13.88 per share in cash. The total transaction is valued at approximately $24.9 billion.

Submission + - MS: Windows Phone 8 WiFi Vulnerable, Cannot Be Patched

Freshly Exhumed writes: Microsoft advises that a cryptographic problem in the PEAP-MS-CHAPv2 protocol used in Windows Phone 8 to provide WPA2 authentication allows a victim’s encrypted domain credentials to be collected by an attacker posing as a typical WiFi access point. Redmond further states that this problem cannot be patched, although a set of manually entered configuration changes involving root certificates on all WP8 phones and on WiFi access points will apparently address the issue. WP7.8 phones are likewise vulnerable.

Submission + - Scientists predict new structure in turbulence

liceor writes: A story on phys.org and eurekalert describes a new understanding of how turbulence works.
The article describes a new way of predicting structure within turbulence near walls, which is important because a lot of power is used by ships, planes and automobiles to overcome the drag caused by turbulence.
Although the equations that govern fluid flow were discovered in the early 1800s, nobody had figured out a way to predict recurring structure in wall turbulence directly from these equations. This is mainly because the massive range of scales of motion involved are all coupled.
The paper describes how wall turbulence can be broken down into constituent blocks that can be simply pieced together, lego-like, to approach and eventually get back to the full equations. The calculations are simple enough to be done on a laptop and just a few blocks can give realistic-looking flows.

Intel

Submission + - Apple could drop Intel for ARM in iMacs/MacBooks (project-disco.org)

An anonymous reader writes: Bloomberg reported scuttlebutt from Apple execs that the Cupertino company is considering dropping Intel chips from their iMac and MacBook lines so they have the same processor across their full range of products. Not good news for Intel, which is quickly being displaced by ARM's more efficient chips that are moving up from mobile phones and smack dab right into the middle of Intel's market.

From Project DisCo article: "Given that iMacs and MacBooks — according to Phil Schiller at Apple’s most recent product launch — are the most popular line of desktops and laptops ever to be sold, losing the battle to remain their central processing unit would be devastating to Intel. Conversely, it would signal that ARM is now the top-dog in the microprocessor world and might be the symbolic line that signals that disruption has officially occurred."

Ubuntu

Submission + - New Ubuntu annouced: Raring Ringtail. Focus on mobile. (markshuttleworth.com)

Volanin writes: So what will we be up to in the next six months? We have two short cycles before we’re into the LTS, and by then we want to have the phone, tablet and TV all lined up. So I think it’s time to look at the core of Ubuntu and review it through a mobile lens: let’s measure our core platform by mobile metrics, things like battery life, number of running processes, memory footprint, and polish the rough edges that we find when we do that. The tighter we can get the core, the better we will do on laptops and the cloud, too. [...] We’ll make something wonderful, and call it the Raring Ringtail.
