+ - 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:

Thanks to the MariaDB Foundation! We look forward to working with you.
