Linux accessibility – what is it and why does it matter
I stopped using Windows because I could no longer afford to use it. At the time when I completely switched to Linux (approximately June of 2007) the price for a popular screen magnifier was US$600 to US$700, not including the price of upgrades to new versions when they were made available. Even to this day, the price for a standard version of a very popular screen reader among blind users starts at US$895. Oh, the software does its job, but you have to go into debt to use your computer. That’s tough if you are a student or if you need your computer for work related activities. Believe me, I’ve been there.
In 2007 I realized that the Compiz Enhanced Zoom Desktop (or simply Ezoom) plugin did everything I needed a screen magnifier to do – it did it well, and it did it for free! I was sold on Linux from that point on.

Android fragmentation: one developer encounters 3,997 devices
The developers logged 3,997 distinct devices, the most popular of which was the Samsung Galaxy S II. This figure was inflated quite a bit by custom ROMs, which overwrite the android.build.MODEL variable and cause those phones to be logged as separate devices. 1,363 types were logged only once, and while some were custom ROMs bucking the numbers, a good few were just massively unpopular devices—for example, the Hungarian 10.1-inch Concorde Tab.

FreeBSD 10 To Use Clang Compiler, Deprecate GCC
Going back to 2009, FreeBSD developers have worked to replace GCC with LLVM/Clang. Over time, there’s been numerous improvements especially with the FreeBSD 9.0 release. The FreeBSD developers are interested in doing away with the GPL-licensed GNU Compiler Collection and instead use the Apple-sponsored LLVM/Clang work that’s under a BSD-like license.

Linux 3.3: Finally a little good news for bufferbloat
Bufferbloat, as you’ll recall from my 2011 predictions column, is the result of our misguided attempt to protect streaming applications (now 80 percent of Internet packets) by putting large memory buffers in modems, routers, network cards, and applications. These cascading buffers interfere with each other and with the flow control built into TCP from the very beginning, ultimately breaking that flow control, making things far worse than they’d be if all those buffers simply didn’t exist.
Bufferbloat was named by Jim Gettys of Bell Labs, who has become our chief defender against the scourge, attempting to coordinate what’s become a global response to the problem.
…
What AQM does is monitor the buffer, and signal the end points to slow down any time the buffer starts to fill, either due to that one transfer or competing transfers, by dropping or marking packets. So the buffer is kept (almost) empty, except when it is handling a burst of traffic. So the steady state latency of the buffer, rather than being the size of the buffer, is set by the size of the bursts in traffic. The size of the buffer becomes almost irrelevant.
Replicant project
Replicant is a fully free Android distribution running on several devices. It is a free software project.
via About | Replicant project.
On this release, here is a quick summary of which major components are working and which are not:
- Telephony is stable enough, there is working in-call volume change and audio routing, though we miss some features like conferencing
- SMS are working nicely, including multi-part messages, both on sending and receiving
- Data has a minimal implementation that is far from being ready (but can be set up manually), so this will be for next time
- Some other minimal features are there (SIM I/O, DTMF, SIM unlock, etc)
- Some are missing (USSD, working airplane mode for instance)
Raspberry Pi Fedora Remix, our recommended distro, is ready for download!
The Remix is a distribution comprised of software packages from the Fedora ARM project, plus a small number of additional packages that are modified from the Fedora versions or which cannot be included in Fedora due to licensing issues – in particular, the libraries for accessing the VideoCore GPU on the Raspberry Pi.
The SD card image for the Remix includes a little over 640 packages, providing both text-mode and graphical interfaces (LXDE/XFCE) with an assortment of programming languages, applications, system tools, and services for both environments. There are over 16,000 software packages available from the Fedora ARM repositories which can be easily installed using the Internet to customize your system to meet your needs and interests (again, using either command-line or graphical tools).

InstallCDCustomization
Suppose you are installing Ubuntu on a bunch of identical computers, and you already know the answers to certain questions (what country and time zone you’re in, what keyboard you have, how the network should be configured, how you want to partition the hard disk, etc). You can “preseed” the answers to these questions in a very simple configuration file.
