[$] LinuxCon: funding development
[Front] Posted Sep 6, 2012 17:09 UTC (Thu) by n8willis
At LinuxCon 2012, Bradley Kuhn, executive director of the Software
Freedom Conservancy (SFC), presented a session on funding free software
development. SFC's primary mission is to provide organizational and
legal support to free software projects, but it has also been
successful at raising funds to support development time — a task
that many projects find difficult.

[$] Improving Ubuntu's application upload process
[Distributions] Posted Sep 5, 2012 18:07 UTC (Wed) by corbet
There has been a surplus of articles recently on how Linux "lost" the
desktop. Fingers have been pointed in all directions, from the Windows
monopoly to competing desktop projects to Linus Torvalds's management
style. Over in the Ubuntu camp, though, there does not appear to be any
sense that the desktop has been lost; they are still working hard to win
it. Ubuntu's recently-proposed new application
upload process highlights its vision of the desktop and what they
think needs to be done to make things happen there.

Look and feel lawsuits, the second time around
[Front] Posted Aug 28, 2012 17:47 UTC (Tue) by corbet
The thicket of lawsuits surrounding the mobile industry has grown to the
point that it is hard for any individual action to stand out. If any case
has managed to make itself visible in that crowd anyway, it is the battle
between Apple and
Samsung currently being fought in the US. The first stage of that battle
has just been resolved, heavily in Apple's favor. It will be some time
before this story truly reaches its end, but some of the more interesting
implications for the industry, and for free software, can already be seen.

Mobile patent wars: Google goes on the attack
[Front] Posted Aug 22, 2012 18:19 UTC (Wed) by corbet
Whenever one looks at the mobile patent wars, it is natural to conclude
that everybody is suing everybody else. Thus far, though, that has not
actually been true. Google has been on the receiving end of a number of
lawsuits, either directly or indirectly via attacks on manufacturers
shipping Android devices, but Google has not, itself, launched patent
attacks against others. That situation has just changed, though, with the
report
that Google has filed a case against Apple with the US International
Trade Commission.

Link-time optimization for the kernel
[Kernel] Posted Aug 21, 2012 14:16 UTC (Tue) by corbet
The kernel tends to place an upper limit on how quickly any given workload
can run, so it is unsurprising that kernel developers are always on the
lookout for ways to make the system go faster. Significant amounts of work
can be put into optimizations that, on the surface, seem small. So when
the opportunity comes to make the kernel go faster without the need to
rewrite any performance-critical code paths, there will naturally be a fair
amount of interest. Whether the "link-time optimization" (LTO) feature
supported by recent versions of GCC is such an opportunity or not is yet to
be proved, but Andi Kleen is determined to find out.

The Linux digital audio workstation - Part 2
[Development] Posted Aug 15, 2012 18:51 UTC (Wed) by jake
This is part 2 of Dave Phillips's tour through Linux digital audio
workstations (DAWs). Take a peek at part 1 for some background and the first
five DAWs. These are good times for Linux as a platform for audio
production, and great work is going on in Linux audio development. Let's
look at some more of that work.

The GNOME project at 15
[Front] Posted Aug 14, 2012 21:23 UTC (Tue) by corbet
On August 15, 1997, Miguel de Icaza announced
the launch of the GNOME project. In the following years, GNOME has seen
more than its share of ups and downs; it must be considered one of the
community's most successful and most controversial projects. This is a
moderately significant anniversary, so it makes some sense to have a look
at where GNOME came from and speculate on where the project may be heading.

Adobe ventures into open fonts
[Front] Posted Aug 7, 2012 20:09 UTC (Tue) by n8willis
Adobe surprised many in open source circles with its August 2 release
of Source Sans Pro, an open font made available under the standard SIL
Open Font License (OFL). The font covers a range of languages and includes some uncommon features, but its greatest impact may be the company's interest in engaging with the open source community.

Testing for kernel performance regressions
[Kernel] Posted Aug 3, 2012 21:22 UTC (Fri) by corbet
It is not uncommon for software projects β free or otherwise β to include a
set of tests intended to detect regressions before they create problems for
users. The kernel lacks such a set of tests. Recently, though, we have
seen the publication of some results from tests intended to highlight
memory management regressions; they paint an interesting picture of where
kernel development is going.

TCP Fast Open: expediting web services
[Kernel] Posted Aug 1, 2012 21:07 UTC (Wed) by mkerrisk
The upcoming 3.6 kernel will contain client-side support for the TCP "fast
open" protocol extension. This work, contributed by Google, was first covered in LWN almost one year ago; now we
have a detailed overview of what fast open is, why it matters, and how it
works.

Rodriguez: All 48 Liberated Pixel Cup entries reviewed
[Development] Posted Sep 7, 2012 22:42 UTC (Fri) by n8willis
On his blog, Juan "Nushio" Rodriguez has been systematically reviewing all of the entries in the OpenGameArt project's Liberated Pixel Cup (LPC) free software game contest in recent weeks. Reviews of all 48 games are now available. Note that these are personal assessments, not the results of LPC's official judges. Note also that Rodriguez is an LPC contestant, so he had someone else review his own entry, presumably to add a bit more suspense.

Tinnes: Introducing Chrome's next-generation Linux sandbox
[Security] Posted Sep 7, 2012 13:28 UTC (Fri) by corbet
Julien Tinnes describes
the new sandbox mechanism for the Chrome browser under Linux.
"In a similar, but very limited, fashion, this is what we have now in
Chrome: we stacked the seccomp-bpf sandbox on top of the setuid
sandbox. The setuid sandbox gives a few easy to understand semantic
properties: no file system access, no process access outside of the
sandbox, no network access. It makes it much easier to layer a seccomp-bpf
sandbox on top."

Study for US Congress outlines options against patent trolls (The H)
[Development] Posted Sep 7, 2012 13:27 UTC (Fri) by n8willis
The H takes a look at a report from the US Congressional Research Service about patent trolling and potential fixes to the system. "According to the researchers, it is worth considering whether to generally shorten the periods of protection for software patents because the trolls file most of their litigation claims in the last three years of the 20-year term. A patent could also be invalidated if it hasn't been practised for a number of years, they added."

Garrett: UEFI Secure boot in Fedora: status update
[Distributions] Posted Sep 5, 2012 20:36 UTC (Wed) by ris
Matthew Garrett has a progress report on
implementing secure boot in Fedora. "The infrastructure for signing the bootloader binaries is now implemented. pesign is in the archive and being used to sign shim, grub2 and the kernel. At the moment they're all being signed by test keys, and the private key is actually in the pesign package. This is, obviously, not intended for production use - it's just to ensure that we can build correctly signed images. We've proof-of-concepted signing via cryptographic hardware and will shortly be deploying new build systems dedicated to building the signed binaries. These won't be general access systems and will have a lightly modified mock configuration to ensure that the crypto hardware is available to the build chroots, but otherwise there's nothing special about them."
