Linux 3.5 Released
diegocg writes "Linux 3.5 has been released. New features include support for metadata checksums in Ext4, userspace probes for performance profiling with systemtap/perf, a simple sandboxing mechanism that can filter syscalls, a new network queue management algorithm designed to fight bufferbloat, support for checkpointing and restoring TCP connections, support for TCP Early Retransmit (RFC 5827), support for android-style opportunistic suspend, btrfs I/O failure statistics, and SCSI over Firewire and USB. Here's the full changelog."
Btrfs is stable enough for real data, if you run current releases (latest 3.4 or 3.5 kernel and btrfs-progs-19 current). I use it in both single drive systems and raid1 configurations with Fedora 17. Prior to converting the systems, I ran extensive failure testing (e.g., pulling power / data connection during active writes, system crashes, using a failing drive with media errors as part of a raid1, etc.) for about a month. I never lost a single byte of data in any test, confirmed by checksum scans on all data (against a backup) after each test cycle.
I actually trust btrfs now more than ext4 due to the ability to scrub the data and confirm integrity, which I do daily or weekly depending on the system.
Can You Say Linux? I Knew That You Could.
Android scales graphis just fine IMO. if you run something like an older game that was designed for a lower dpi device, it just scales it. Generally you have the option to allow it to run smaller in its native resolution as well. Many of the android games use vectors for sprites, so asides from backgrounds looking pixelated, the sprites generally look pretty decent. I dunno, I went from a phone with an 800x480 display to a tablet with a 1280x800 display. If you ask me, android, at least ICS and beyond, handles high resolutions very well. It will scale the UI to match the dpi of the phone. I don't think apple has any real advantage here.

Linux always succeeded - only not anywhere you can see it.
Linux still runs 80%+ of the world's internet, Linux runs a vast majority of embedded devices. This is the reason Google got into it - it already was there when Google appeared and started to think "what web OS do we use for our HPC system" - it was pretty obvious to them to use the market leader in those arenas - Linux - and when they decided to go for an embedded phone device, they again chose the market leader in that area - Linux.
Linux made Google big, not the other way round.
