Announcing Snappy Ubuntu
Awesome! I was completely unaware this was coming down the pipeline.
A new, transactionally updated Ubuntu for the cloud. Ubuntu Core is a new rendition of Ubuntu for the cloud with transactional updates. Ubuntu Core is a minimal server image with the same libraries as today’s Ubuntu, but applications are provided through a simpler mechanism. The snappy approach is faster, more reliable, and lets us provide stronger security guarantees for apps and users — that’s why we call them “snappy” applications.

Snappy apps and Ubuntu Core itself can be upgraded atomically and rolled back if needed — a bulletproof approach to systems management that is perfect for container deployments. It’s called “transactional” or “image-based” systems management, and we’re delighted to make it available on every Ubuntu certified cloud.

This program creates an EBS snapshot for an Amazon EC2 EBS volume. To
help ensure consistent data in the snapshot, it tries to flush and
freeze the filesystem(s) first as well as flushing and locking the
database, if applicable.

Filesystems can be frozen during the snapshot. Prior to Linux kernel
2.6.29, XFS must be used for freezing support. While frozen, a
filesystem will be consistent on disk and all writes will block.

There are a number of timeouts to reduce the risk of interfering with
the normal database operation while improving the chances of getting a
consistent snapshot.

If you have multiple EBS volumes in a RAID configuration, you can
specify all of the volume ids on the command line and it will create
snapshots for each while the filesystem and database are locked. Note
that it is your responsibility to keep track of the resulting snapshot
ids and to figure out how to put these back together when you need to
restore the RAID setup.

Some really cool-looking UNIX command line utils, packaged in Debian (and therefore in Ubuntu too). A few of these I've reimplemented separately, but it's always good to replace a hack with a more widely available "official" tool. Thanks, Joey Hess!
sponge: accept input, wait til EOF, then rewrite a file;
chronic: runs a command quietly unless it fails;
combine: combine the lines in two files using boolean operations;
ifdata: get network interface info without parsing ifconfig output;
ifne: run a program if the standard input is not empty;
isutf8: check if a file or standard input is utf-8;
lckdo: execute a program with a lock held;
mispipe: pipe two commands, returning the exit status of the first;
parallel: run multiple jobs at once;
pee: tee standard input to pipes;
sponge: soak up standard input and write to a file;
ts: timestamp standard input;
vidir: edit a directory in your text editor;
vipe: insert a text editor into a pipe;
zrun: automatically uncompress arguments to command

o2 Broadband Dongle Working on Ubuntu 10.04
the Huawei E1752 dongle does that horrible thing where it defaults to acting as a USB storage device containing the Windows drivers, instead of acting as a 3G modem by default. usb_modeswitch should be in the Ubuntu base install to deal with this crap

'a driver for Xbox and Xbox360 gamepads. It works by reading the raw data from the controller with the userspace library libusb and then passes the interpreted data to the kernel via uinput. This allows xboxdrv to provide regular joystick and event devices, which makes it compatible with all Linux software.'

Canonical _finally_ open source (under the AGPL) their bug tracker/project hosting platform. yay! here's hoping it's reasonably easy to deploy. maybe it would be viable for the ASF... hmm
