Meet Cyanogen, The Startup That Wants To Steal Android From Google (Forbes)

Tuesday 24th of March 2015 09:39:04 PM
Forbes takes a look at Cyanogen, and its prospects in the phone market. "Cyanogen has a chance to snag as many as 1 billion handsets, more than the total number of iPhones sold to date, according to some analysts. Fifty million people already run Cyanogen on their phones, the company says. Most went through the hours-long process of erasing an Android phone and rebooting it with Cyanogen. [Kirt] McMaster is now persuading a growing list of phone manufacturers to make devices with Cyanogen built in, rather than Google’s Android. Their phones are selling out in record time. Analysts say each phone could bring Cyanogen a minimum of $10 in revenue and perhaps much more."

Van de Ven: Deprecating old crypto

Tuesday 24th of March 2015 08:46:05 PM
Worth a read: this post from Arjan van de Ven on the difficulty of removing old, insecure cryptographic algorithms from a Linux distribution. "But more, and this is a call to action: If you're working on an open source project that uses crypto, please please don't opencode crypto algorithm usage. The algorithm may be outdated at any time and might have to go away in a hurry."

Google: Maintaining digital certificate security

Tuesday 24th of March 2015 12:00:49 AM
It seems it was about time for another certificate authority horror story; the Google Online Security Blog duly delivers. "CNNIC responded on the 22nd to explain that they had contracted with MCS Holdings on the basis that MCS would only issue certificates for domains that they had registered. However, rather than keep the private key in a suitable HSM, MCS installed it in a man-in-the-middle proxy. These devices intercept secure connections by masquerading as the intended destination and are sometimes used by companies to intercept their employees’ secure traffic for monitoring or legal reasons. The employees’ computers normally have to be configured to trust a proxy for it to be able to do this. However, in this case, the presumed proxy was given the full authority of a public CA, which is a serious breach of the CA system."

Windows 10 to make the Secure Boot alt-OS lock out a reality (Ars Technica)

Monday 23rd of March 2015 08:35:16 PM

Ars Technica is one of several news outlets to report on a change announced in Microsoft's Windows 10 plans. Though the headlines (including Ars Technica's) paint a rather bleak scenario, the details are not as clear-cut. The UEFI "Secure Boot" mechanism was introduced with Windows 8, at which time Microsoft's OEM-certification rules mandated that hardware must include a means for the local user to disable Secure Boot. The Windows 10 certification rules does not include the mandated disable switch. Writes Peter Bright: "Should this stand, we can envisage OEMs building machines that will offer no easy way to boot self-built operating systems, or indeed, any operating system that doesn't have appropriate digital signatures. This doesn't cut out Linux entirely—there have been some collaborations to provide Linux boot software with the 'right' set of signatures, and these should continue to work—but it will make it a lot less easy." Note, also, that the only source for this story appears to be a presentation from a Microsoft event in Shenzhen, China. Bright adds that he has contacted Microsoft seeking clarification, but has so far received no reply.

Linus has released the 4.0-rc5 prepatch, saying "There's nothing particularly worrisome going on, although I'm still trying to think about the NUMA balancing performance regression. It may not be a show-stopper, but it's annoying, and I want it fixed. We'll get it, I'm sure."

  • GNOME Builder - 3.16.2
    I released 3.16.0 a couple weeks ago without much fanfare. Despite many months of 16-hour days and weekends, it lacked some of the features I wanted to get into the "initial" release. So I didn't stop. I kept pushing through to make 3.16.2 the best that I could.
  • PacketFence v5.0 released
    The Inverse team is pleased to announce the immediate availability of PacketFence 5.0.0. This is a major release with new features, enhancements and important bug fixes. This release is considered ready for production use and upgrading from previous versions is strongly advised.
  • What are good open-source log monitoring tools on Linux
    In an operating system, logs are all about keeping track of events, be it critical system errors, resource usage warnings, transaction history, application status, or user activities. These logs, which are stored as (text or binary) files in the system, are useful for system auditing, debugging and maintenance. However, with so many different system entities generating log files, and even at growing rate, the challenge as a system admin is to how to "consume" these log files effectively.
  • Apache Fortress Core 1.0-RC40 released !
  • Say Hello to Open Source Puppet 4!
    Production-ready Open Source Puppet 4 is now available! We’re excited to announce new features and enhancements that will extend your use of Puppet for faster, more consistent management of server configurations.
