LibreOffice Viewer for Android released

6 hours 6 min ago
The Document Foundation has announced the availability of the LibreOffice viewer for Android systems. And it's not just for viewing: "LibreOffice Viewer also offers basic editing capabilities, like modifying words in existing paragraphs and changing font styles such as bold and italics. Editing is still an experimental feature which has to be enabled separately in the settings, and is not stable enough for mission critical tasks."

A security study of Docker images

7 hours 33 min ago
The folks at Banyan have looked into the security state of the images stored on Docker Hub and published their results. "More than a third of all images have high priority vulnerabilities and close to two-thirds have high or medium priority vulnerabilities. These statistics are especially troublesome because these images are also some of the most downloaded images (several of them have hundreds of thousands of downloads)."

[$] SourceForge replacing GIMP Windows downloads

10 hours 27 min ago

In 2013, we reported that SourceForge.net had started to redirect the download links clicked on by some users, providing those users with an installer program that bundled in not just the software the user had requested, but a set of side-loaded "utilities" as well. The practice raised the ire of many in the community, even though it was an optional service that SourceForge offered to project owners. Matters may have changed recently, however, as the GIMP project discovered that "GIMP for Windows" downloads had suddenly become side-loading installers—and that the project could no longer access the SourceForge account that was used to distribute them.

LWN staff celebrated the US Memorial Day holiday on Monday this week, so the Weekly Edition will come out on the holiday schedule — one day later than usual. We will return to our normal schedule next week. Thank you all, as always, for supporting LWN.

White House sides with Oracle, tells Supreme Court APIs are copyrightable (ArsTechnica)

Wednesday 27th of May 2015 08:21:17 PM
Ars Technica reports that the US Justice Department has sided with Oracle in its dispute with Google. "The dispute centers on Google copying names, declarations, and header lines of the Java APIs in Android. Oracle filed suit, and in 2012, a San Francisco federal judge sided with Google. The judge ruled that the code in question could not be copyrighted. Oracle prevailed on appeal, however. A federal appeals court ruled that the "declaring code and the structure, sequence, and organization of the API packages are entitled to copyright protection." Google maintained that the code at issue is not entitled to copyright protection because it constitutes a "method of operation" or "system" that allows programs to communicate with one another." (Thanks to Martin Michlmayr)

Mourning Marco Pesenti Gritti

Wednesday 27th of May 2015 02:06:35 PM
The GNOME community is mourning the loss of developer Marco Pesenti Gritti, who passed away on May 23. "He was the most passionate and dedicated hacker I knew, and I know he was extremely respected in the GNOME community, for his work on Epiphany, Evince and Sugar among many others, just like he was at litl. Those who knew him personally know he was also an awesome human being."

Jonathan Riddell forced out of Kubuntu

Wednesday 27th of May 2015 01:40:51 AM
Scott Kitterman has posted a series of emails around the the Ubuntu Community Council's decision to remove Jonathan Riddell as the leader of the Kubuntu project. He has also stated his intent to leave the Ubuntu community. "I also wish to extend my personal apology to the Kubuntu community for keeping this private for as long as we did. Generally, I don’t believe such an approach is consistent with our values, but I supported keeping it private in the hope that it would be easier to achieve a mutually beneficial resolution of the situation privately. Now that it’s clear that is not going to happen, I (and others in the KC) could not in good faith keep this private."

Trouble with the May 22 PostgreSQL update

Tuesday 26th of May 2015 09:45:04 PM
If you run PostgreSQL and have applied one of the updates that were released on May 22, it would be a good idea to read this page about an unfortunate bug in those releases. In some cases, the problem can cause the server to fail to restart after a crash. There is a new release in the works; meanwhile, a workaround is available.

The Moose is loose: Linux-based worm turns routers into social network bots (Ars Technica)

Tuesday 26th of May 2015 09:28:54 PM
Ars Technica takes a look at the latest malware threat. "A worm that targets cable and DSL modems, home routers, and other embedded computers is turning those devices into a proxy network for launching armies of fraudulent Instagram, Twitter, and Vine accounts as well as fake accounts on other social networks. The new worm can also hijack routers' DNS service to route requests to a malicious server, steal unencrypted social media cookies such as those used by Instagram, and then use those cookies to add "follows" to fraudulent accounts. This allows the worm to spread itself to embedded systems on the local network that use Linux-based operating systems. The malware, dubbed "Linux/Moose" by Olivier Bilodeau and Thomas Dupuy of the security firm ESET Canada Research, exploits routers open to connections from the Internet via Telnet by performing brute-force login attempts using default or common administrative credentials. Once connected, the worm installs itself on the targeted device."

Fedora 22 released

Tuesday 26th of May 2015 02:15:57 PM
The Fedora 22 release is out. "If this release had a human analogue, it'd be Fedora 21 after it'd been to college, landed a good job, and kept its New Year's Resolution to go to the gym on a regular basis. What we're saying is that Fedora 22 has built on the foundation we laid with Fedora 21 and the work to create distinct editions of Fedora focused on the desktop, server, and cloud (respectively). It's not radically different, but there are a fair amount of new features coupled with features we've already introduced but have improved for Fedora 22." LWN's preview of Fedora 22 was published in the May 21 Weekly Edition.

The end for Mandriva

Tuesday 26th of May 2015 01:24:41 PM
An anonymous reader has pointed out that Mandriva is currently being liquidated (page in French). The company brought in €553,000 in 2013, but that is seemingly not enough to keep it going in 2015. It is a sad end for a company that has been pursuing the desktop Linux dream since 1998.

Kernel prepatch 4.1-rc5

Monday 25th of May 2015 03:45:09 AM
The fifth 4.1 prepatch is out for testing. "So we're on schedule for a normal 4.1 release, if it wasn't for the fact that the timing looks like the next merge window would hit our yearly family vacation. So we'll see how that turns out, I might end up delaying the release just to avoid that (or just delay opening the merge window)."

[$] A tale of two data-corruption bugs

Sunday 24th of May 2015 02:09:45 PM
There have been two bugs causing filesystem corruption in the news recently. One of them, a bug in ext4, has gotten the bulk of the attention, despite the fact that it is an old bug that is hard to trigger. The other, however, is recent and able to cause data loss on filesystems installed on a RAID 0 array. Both are interesting examples of how things can go wrong, and, thus, merit a closer look.

Nocera: iio-sensor-proxy 1.0 is out!

Friday 22nd of May 2015 10:08:09 PM

At his blog, Bastien Nocera announces the 1.0 release of iio-sensor-proxy, a framework for accessing the various environmental sensors (e.g., accelerometer, magnetometer, proximity, or ambient-light sensors) built in to recent laptops. The proxy is a daemon that listens to the Industrial I/O (IIO) subsystem and provides access to the sensor readings over D-Bus. As of right now, support for ambient-light sensors and accelerometers is working; other sensor types are in development. The current API is based on those used by Android and iOS, but may be expanded in the future. "For future versions, we'll want to export the raw accelerometer readings, so that applications, including games, can make use of them, which might bring up security issues. SDL, Firefox, WebKit could all do with being adapted, in the near future."

Announcing qboot, a minimal x86 firmware for QEMU

Thursday 21st of May 2015 03:57:11 PM
The announcement of Clear Containers (which guest author Arjan van de Ven described in an LWN article from this week) seems to have sparked some interesting work on QEMU that resulted in qboot: "a minimal x86 firmware that runs on QEMU and, together with a slimmed-down QEMU configuration, boots a virtual machine in 40 milliseconds on an Ivy Bridge Core i7 processor." Paolo Bonzini announced the project (code is available at git://github.com/bonzini/qboot.git), which is quite new: "The first commit to qboot is more or less 24 hours old, so there is definitely more work to do, in particular to extract ACPI tables from QEMU and present them to the guest. This is probably another day of work or so, and it will enable multiprocessor guests with little or no impact on the boot times. SMBIOS information is also available from QEMU."
