+ - 258 Matthew Garrett Gives Tips to Survive Bricked UEFI Samsung Laptops->

Submitted by hypnosec
hypnosec (2231454) writes "UEFI guru Matthew Garrett who cleared the Linux kernel in Samsung laptop bricking issues has come to rescue beleaguered users by offering a survival guide enabling them to avoid similar issues in the future. According to Garrett, storage space constraints in UEFI storage variables is the reason Samsung laptops end up bricking themselves. Garrett said that if the storage space utilized by the UEFI firmware is more than 50 per cent full the laptop will refuse to start and end up being bricked. To prevent this from happening he has provided a Kernel patch that would ensure that Linux does not fill up more than 50 per cent of UEFI firmware's storage space."

+ - 257 Longest running Linux distribution Slackware switching to the MariaDB database ->

Submitted by
Gerardo Zamudio
Gerardo Zamudio writes "The big news here is the removal of MySQL in favor of MariaDB. This shouldn't really be a surprise on any level. The poll on LQ showed a large majority of our users were in favor of the change. It's my belief that the MariaDB Foundation will do a better job with the code, be more responsive to security concerns, and be more willing to work with the open source community. And while I don't think there is currently any issue with MySQL's licensing of the community edition for commercial uses, several threads on LQ showed that there is confusion about this, whereas with MariaDB the freedom to use the software is quite clear. Thanks are due to Heinz Wiesinger for his work on transitioning the build script, testing, and getting us all behind this move. He's been working with MariaDB (and their developers) for several years now. Vincent Batts also had a hand in the early discussions here — he met Daniel Bartholomew of MariaDB on a train last year and got a copy of the source to play with to pass the time on the journey (ah, the miracle of thumbdrives :), and was impressed with not only MariaDB itself, but also with the welcome that Slackware was getting. We expect they'll be responsive to any concerns we have. In the vast majority of situations, MariaDB is entirely compatible with existing MySQL databases and will drop right in with no changes required. There's an article available outlining the areas in which MariaDB differs from MySQL that I'd recommend reading:
https://kb.askmonty.org/v/mariadb-versus-mysql-compatibility/
Thanks to the MariaDB Foundation! We look forward to working with you.

+ - 235 Ask Slashdot: new to Linux, which build?-> 3

Submitted by Anonymous Coward
An anonymous reader writes "I'm a very new user to Linux looking for a distro that allows me to control and customize, but I'm not sure where to start. I had a friend install Ubuntu 12.04 on my computer, with the E17 window manager and somehow I managed to crash it during the copying of some non-important files and now my computer won't boot (the hardware's fine though). I've found descriptions of Arch Linux to be spot on to what I'm looking for and want ( /. user serviscope_minor mentioned Arch a couple weeks ago and it caught my attention), but my experience in the terminal is literally about an hour.
That said, I really want to learn more, don't mind hard work, enjoy challenges, and am perfectly willing to spend hours and hours for months on end to learn command line.
I grew up in Windows, and these days use a notebook running an old version of Ubuntu with GNOME exclusively--I'm comfortable in the GUI of Linux systems, but that doesn't translate into any kind of behind-the-scenes ability...
Any suggestions, projects to start with, books to read, or tutorials to do to try would be appreciated."

+ - 214 A 50 Gbps TCP connection with Multipath TCP->

Submitted by Olivier Bonaventure
Olivier Bonaventure (2873367) writes "The TCP protocol is closely coupled with the underlying IP protocol.
Once a TCP connection has been established through one IP address,
the other packets of the connection must be sent from this address. This
makes mobility and load balancing difficult. Multipath TCP is
a new extension that solves these old problems by decoupling TCP from
the underlying IP. A Multipath TCP connection can send packets over
several interfaces/addresses simultaneously while remaining backward
compatible with existing TCP applications. Multipath TCP has several use
cases including smartphones that can use both WiFi and 3G or servers
that can pool multiple high-speed interfaces. Christoph Paasch, Gregory
Detal and their colleagues who develop the implementation of
Multipath TCP in the Linux kernel have achieved 50 Gbps for a single TCP
connection by pooling together six 10 Gbps interfaces. See here for
technical details and full source code."

+ - 218 Chinese open source community is brought into the global Ubuntu community->

Submitted by GovCheese
GovCheese (1062648) writes "Canonical, the software company that manages and funds Ubuntu, announced that the Chinese Ministry of Industry and Information Technology will base their national reference architecture for standard operating systems on Ubuntu, and they will call it Kylin. Arguably China is the largest desktop market and the announcement has important implications. Shuttleworth's phrasing of, “The release of Ubuntu Kylin brings the Chinese open source community into the global Ubuntu community,” will irk many who already feel Shuttleworth controversial, but the partnership further cements Ubuntu as an open-source influencer. This is a win for Ubuntu. Is it a win for the open-source community?"

psykocrime writes "The crazy kids at Fogbeam Labs have started a discussion about Google and their relationship with the Open Web, and questioning who will step up to defend these principles, even as Google seem to be abdicating their position as such a champion. Some candidates mentioned include Yahoo, IBM, Red Hat, Mozilla, Microsoft and The Wikimedia Foundation, among others. The question is, what organization(s) have BOTH the necessary clout and the required ethical principles, to truly champion the Open Web, in the face of commercial efforts which are clearly inimical to Open Source, Open Standards, Libre Culture and other elements of an Open Web?"

Submitted by Freshly Exhumed
Freshly Exhumed (105597) writes "Sean Michael Kerner has revealed an inconvenient truth: earlier this month, 'Google Chrome running Chrome OS was hailed as being a survivor in the Pwnium/Pwn2own event that hacked IE, Firefox and Chrome browsers on Windows. Apple's Safari running on Mac OS X was not hacked and neither (apparently) was Chrome on Chrome OS. Google disclosed this morning that Chrome on Chrome OS had in fact been exploited — albeit, unreliably. The same researcher that took Google's money last year for exploiting Chrome, known publicly only as 'PinkiePie' was awarded $40,000 for exploiting Chrome/Chrome OS via a Linux kernel bug, config file error and a video parsing flaw.' So, was it really Google Chrome, or was Linux to blame?"

Submitted by Anonymous Coward
An anonymous reader writes "The team at Pwnie Express seems to have a lot of trouble standing still, as it doesn’t seem more than a few months go by before they are talking about yet another disruptive open source product that they are about to unleash on the security community.

First it was their Pwn Plug, which combined an off the shelf SheevaPlug with a feature packed open source firmware that turned it into an incredibly capable security tool. Then came the absolutely diabolical Power Pwn, which hid the same type of functionality into what looked like a standard power strip.

Today they’ve launched their latest product, continuing along the same line of hiding cutting edge open source security tools in plain sight: the Pwn Pad."

+ - 155 Distributed File System for Debian-based Road Warriors?

Submitted by hweimer
hweimer (709734) writes "I manage a small network which includes some clients that are regularly deployed in locations where there is no or only poor internet access. Currently, local copies of data for these clients are created and merged back more or less manually, which naturally creates all sorts of problems. So I'm looking now for a distributed file system so that each client has always access to a local copy, which is automatically re-synced once it comes back online. Storage space is not critical, nor is obscene read/write performance. An additional requirement is that it has to be included in Debian, at least in the upcoming "wheezy" release. Any recommendations?"

Submitted by Anonymous Coward
An anonymous reader writes "We were caught in a situation where if we upgraded Postfix, we might break the installed MySQL client. There are a couple of things wrong with this situation. First off, why, oh why, does Postfix require a MySQL client to be installed? Postfix is our MTA, a mail transfer agent, setup because it is easy to configure and we need to do a couple things differently from what is available out of the box. We have absolutely no use for MySQL on every server in the environment. Secondly, why was the third party MySQL (or is that first party, since it is from Oracle?) installed over the default filesystem?"

It’s a solution to problem which does not exist." The GNOME response to Ubuntu's Mir is that they will now be rushing support for the GNOME desktop on Wayland. Over the next two release cycles they plan to iron out the Wayland support for the GNOME Shell, the GTK+ toolkit, and all GNOME packages so that by this time next year you can be running GNOME entirely on Wayland while still having X11 fall-back support."
