Playing with ansible, its "ec2" module came to my attention: it is intended to manage virtual machines in Amazon's EC2 cloud. The idea is that you describe a system with the property "needs to run in Amazon's cloud", and ansible then starts the machine if it isn't there already. In order to get to the point where this can be played with, a working version of the euca2ools package was required first. Packaging was mostly a no-brainer, and a package is currently under review and will end up in pkgsrc eventually. The more interesting part was to verify if the pkg actually worked as expected. This proved tricky for two reasons: 1) my overall lack of how to use the Amazon AWS command line tools (ec2-ami-tools, ec2-api-tools), and 2) the fact that euca2ools is mostly written for the Eucalyptus Cloud infrastructure, which just happens to be compatible with Amazon AWS. To give future parties something to google, here are the steps that to fire up a NetBSD machine in the Amazon cloud.
If you're wondering what graphics hardware / driver is best if you intend to do much gaming within Wine or CrossOver on Linux, a CodeWeavers' developer responsible for much of the Direct3D layer spoke about his experiences with gaming on Wine for the best results.

Semi-manual LVM disk partitioning guide for Fedora 18 provides a step-by-step guide on how to customize the disk space allocated to the root logical volume, so that it gets just enough disk space required for the life of the installation.
This is a short tutorial on how to find out weak passwords for your mail users. This will save you you a huge headache since spammers will find out mail accounts with weak passwords and send spam emails which will result in your mail server being blacklisted.
A new Ruby 1.9.3 implementation has appeared in the form of Topaz, announced by its creator Alex Gaynor. Topaz's design goals were simplicity and performance and it was written on top of the RPython translation toolchain, building on the work of the PyPy developers. RPython is a restricted implementation of Python that was developed by the PyPy developers as a route to translating RPython programs into LLVM code. Topaz inherits a high performance garbage collector and "state of the art" just-in-time compiler from RPython, making for a fast Ruby implementation.

Morphlabs, which as built itself up as a provider of OpenStack products designed for service providers and enterprises, has launched a modular, OpenStack-based public cloud platform. Designed for cloud services providers, mCloud Osmium enables them to quickly implement highly-scalable public clouds without the need for large amounts of research, development or capital investments.
Cleaning up the code has been a major focus. "The resulting code base is rather different from the original one, as several million lines of code have been added and removed, by adding new features, solving bugs and regressions, adopting state of the art C++ constructs, replacing tools, getting rid of deprecated methods and obsoleted libraries, and translating twenty-five thousand lines of comments from German to English," the Document Foundation said in its LibreOffice 4.0 announcement. "All of this makes the code easier to understand and more rewarding to be involved with for the stream of new members of our community."
Red Hat (NYSE: RHT) has introduced technical account management (TAM) services for cloud computing, virtualization and storage.

The cron daemon is a core component of any Unix-like operating system. On the surface, cron is a scheduler, meant to run a command at regular intervals. However, if we dig a little deeper into the configuration options, we find that we can configure cron to be as detailed and granular as we need. If you need a script to run every seven minutes, five days a week, between the hours of 8AM and 4PM, cron has you covered.
LibreOffice 4 has just arrived and, at first glance, this popular open-source office suite looks really good.
Last weekend at FOSDEM 2013 in Brussels, Ian Romanick expressed plans to enhance the "out of the box" / automatic configuration experience for games on Linux. He wrote in his talk's abstract, "Every game for desktop PCs has the ability for the user to tune quality and performance settings. However, for the out-of-the-box experience, these games also need to detect the hardware installed in the user's system to select the initial settings. On Windows and Mac, there are a number of system interfaces provided for this purpose, but on Linux it is surprisingly difficult. This talk will cover some current best practices used by shipping Linux games. It will also introduce some interfaces under development to improve the current state of affairs."
The developers behind the Devhelp project, an API documentation browser for the GNOME desktop environment and the GTK+ toolkit, announced yesterday, February 6, the immediate availability for download and testing of Devhelp 3.7.5.
