Submission + - Linux 3.8 released

Submitted by diegocg on Monday February 18, 2013 @09:00PM

diegocg writes: Linux kernel 3.8 has been released. This release includes support in Ext4 for embedding very small files in the inode, which greatly improves the performance for these files and saves some disk space. There is also a new Btrfs feature that allows to replace quickly a disk, a new filesystem F2FS optimized for SSDs, support of filesystem mount, UTS, IPC, PID, and network namespaces for unprivileged users, accounting of kernel memory in the memory resource controller, journal checksums in XFS, an improved NUMA policy redesign and, of course, the removal of support for 386 processors. Many small features and new drivers and fixes are also available. Here's the full list of changes.

Is no government in the world sovereign, for the people, by the people, of the people it represents?

In theory yes, Spain is sovereign. But so is America. If Spain decides that pirating is OK, i guess that Americans can restrict/boycott Spanish IP commercialization.

In the real world, issues like IP protection need worldwide collaboration. Everybody wants their own IP protected, and in order to get that they need to protect the IP of other nations. It's necessary to find a balance, and if every nation listened only to their own citizens, they would never find one.

a dist-upgrade took more than 4 hours instead of the expected 1.5 to 2 hours it takes with ext4.

That's not due to poor small file performance in Btrfs, it's due to poor fsync() performance (which package tools like rpm and dpkg use quite a lot). In this new kernel version the Btrfs fsync() implementation is a lot faster.

Right, because promoting open source GPL-compatible drivers didn't work for Linux.

Oh, wait, it worked. The Linux hardware support is overall quite good (with many hardware manufacturers working with upstream to contribute drivers). In fact, Nvidia is a minority - Intel has the biggest market share in graphic chips (avobe 50%), AMD/ATI is second. Both have contributed open source drivers which are getting better and better.

Submission + - Linux 3.6 released

Submitted by diegocg on Monday October 01, 2012 @10:11AM

diegocg writes: Linux 3.6 has been released. It includes new features in Btrfs: subvolume quotas, quota groups and snapshot diffs (aka "send/receive"). It also includes support for suspending to disk and memory at the same time, a TCP "Fast Open" mode, a "TCP small queues" feature to fight bufferbloat; support for safe swapping over NFS/NBD, better Ext4 quota support, support for the PCIe D3cold power state; and VFIO, which allows safe access from guest drivers to bare-metal host devices. Here's the full changelog.

Unlike Gnome and Unity, the KDE desktop shell is flexible. You can make KDE look like Windows XP/7, OS X, Unity or even Gnome Shell, if someone implemented it. My KDE desktop looks like Unity.

Fedora is going to continue to be a Gnome 3 distro. They are not doing anything special with Mate, they are just going to package it for people that wants to install it.

Since when packaging something is newsworthy?
