F-Droid’s Android App Finally Gets a UI Makeover (xda developers)

Friday 28th of April 2017 10:58:39 PM
Xda developers looks at improvements coming to the F-Droid repository of free/open source apps for Android. The next version of F-Droid will have screenshot and feature graphics, bulk download and install, improved notifications for downloads and pending updates, and the ability to translate apps metadata. "F-Droid is conducting further field tests to ensure that usability issues with the new design are identified and resolved before the alpha releases for v0.103 is rolled out to the public. The team is also inviting feedback and suggestions to further improve the client. Additionally, the team mentions that this is one of the many improvements happening to the broader F-Droid ecosystem in 2017, and there’s more to come."

Bits from the Debian Release Team: release update

Thursday 27th of April 2017 10:37:15 PM
The Debian release team has a few words about the upcoming Debian 9 "stretch" release. "At a recent team meeting, we decided that support for Secure Boot in the forthcoming Debian 9 "stretch" would no longer be a blocker to release. The likely, although not certain outcome is that stretch will not have Secure Boot support." If stretch does not release with Secure Boot support, it is possible that it will be introduced later. Other than that, the number of Release Critical bugs continues to drop and the team is considering the arrangements for the stretch release.

Tor 0.3.0.6 is released: a new series is stable

Thursday 27th of April 2017 09:51:47 PM
Tor 0.3.0.6, the first stable release of the Tor 0.3.0 series, is available. "With the 0.3.0 series, clients and relays now use Ed25519 keys to authenticate their link connections to relays, rather than the old RSA1024 keys that they used before. (Circuit crypto has been Curve25519-authenticated since 0.2.4.8-alpha.) We have also replaced the guard selection and replacement algorithm to behave more robustly in the presence of unreliable networks, and to resist guard- capture attacks."

[$] An alternative TTY layer

Thursday 27th of April 2017 05:25:11 PM
The Linux kernel is highly scalable but, while it runs nicely on the world's largest computers, it is not an entirely comfortable fit on the smallest. The difficulties involved in running Linux on machines with 1MB or less of memory have left an opening for other operating systems, such as Zephyr, with lower memory needs. Some developers have not given up on scaling Linux to the smallest computers, but the approaches they have to take have always been a bit of a hard sell with the rest of the development community. Nicolas Pitre's minitty patch set is a case in point.

[$] The great leap backward

Wednesday 26th of April 2017 04:20:02 PM
Sayre's law states: "In any dispute the intensity of feeling is inversely proportional to the value of the issues at stake". In that context, it is perhaps easy to understand why the discussion around the version number for the next major openSUSE Leap release has gone on for hundreds of sometimes vitriolic messages. While this change is controversial, the openSUSE board hopes that it will lead to more rational versioning in the long term — but the world has a way of interfering with such plans.

This makes grsecurity for Linux 4.9 the last version Open Source Security Inc. will release to non-subscribers."

[$] Which email client for Ubuntu 17.10?

Wednesday 26th of April 2017 02:37:03 PM
An email client was once a mandatory offering for any operating system, but that may be changing. A discussion on the ubuntu-desktop mailing list explores the choices for a default email client for Ubuntu 17.10, which is due in October. One of the possibilities being considered is to not have a default email client at all.

Support for per-service router configuration has been added, along with new plugin interfaces for policy control. (LWN looked at linkerd in early April).

Bash Bunny: Big hacks come in tiny packages (InfoWorld)

Tuesday 25th of April 2017 05:44:13 PM
InfoWorld plays with the Bash Bunny, a USB device for attacking computers. "It can run anything a regular Debian Linux distro can run, such as Python scripts or common Linux commands. To infiltrate other computing devices, Bash Bunny can fake its identity as a trusted media device, networking device, keyboard, or other serial device. For example, it can load itself as a keyboard device and mimic keystrokes. You can download dozens of existing payload scripts, create your own, or ask questions in a fairly active user forum."

[$] Turmoil for Drupal

Tuesday 25th of April 2017 04:02:31 PM

The Drupal content management system (CMS) has been an open-source tool of choice for many web site owners for well over a decade now. Over that time, it has been overseen by its original developer, Dries Buytaert, who is often referred to as the benevolent dictator for life (BDFL) for the project. Some recent events have led a sizable contingent in the Drupal community to question his leadership, however. A request that a prominent developer leave the Drupal community, apparently over elements of his private life rather than any Drupal-related misstep, has led to something of an outcry in that community—it may well lead to a change in the governance of the project.

Collabora Office 5.3 Released

Monday 24th of April 2017 10:15:47 PM
Collabora Office 5.3 has been released with all the fixes and several backported features from the upstream LibreOffice 5.3 release. "The biggest change in this release is the inclusion of a long list of new features, combined with many User Interface improvements, making Collabora Office more powerful and at the same time faster and more comfortable to work with."

[$] Two new block I/O schedulers for 4.12

Monday 24th of April 2017 07:00:08 PM
The multiqueue block layer subsystem, introduced in 2013, was a necessary step for the kernel to scale to the fastest storage devices on large systems. The implementation in current kernels is incomplete, though, in that it lacks an I/O scheduler designed to work with multiqueue devices. That gap is currently set to be closed in the 4.12 development cycle when the kernel will probably get not just one, but two new multiqueue I/O schedulers.

QNX 7 Can Be Fitted With A Qt5 Desktop

  • QNX 7 Can Be Fitted With A Qt5 Desktop
    While QNX remains targeted as an operating system for mobile/embedded solutions, a BlackBerry developer in his spare time has fitted QNX 7 with a Qt5 desktop. QNX 6 and prior had a desktop option, but was removed in QNX 7, which was released this past March. QNX 7.0 also brought support for 64-bit (and maintaining 32-bit) Intel x86 and ARM platforms along with C++14 support. For those wanting to experiment with QNX 7, a BlackBerry kernel developer has been working on making this operating system more desktop friendly.
  • Building a BlackBerry QNX 7 Desktop
    Having Qt allowed me to port one of my favourite applications, SpeedCrunch. It was a simple matter of running ‘qmake’ followed by ‘make’. Next, I ported the QTermWidget library so that I could have terminal windows.

  • State of Sway April 2017
    Development on Sway continues. I thought we would have slowed down a lot more by now, but every release still comes with new features - Sway 0.12 added redshift support and binary space partitioning layouts. Sway 0.13.0 is coming soon and includes, among other things, nvidia proprietary driver support. We already have some interesting features slated for Sway 0.14.0, too! Today Sway has 21,446 lines of C (and 4,261 lines of header files) written by 81 authors across 2,263 commits. These were written through 653 pull requests and 529 issues. Sway packages are available today in the official repos of pretty much every distribution except for Debian derivatives, and a PPA is available for those guys.

  • Surface revenue does a U-boat, and dives

    Revenue generated by Microsoft's Surface hardware during the March quarter was down 26% from the same period the year before, the company said yesterday as it briefed Wall Street.

    For the quarter, Surface produced $831 million, some $285 million less than the March quarter of 2016, for the largest year-over-year dollar decline ever.

  • Acer said to me: "do not use our products with Linux. Find another manufacturer"
    Last year, I bought an Acer notebook and it came with Windows 10. As I didn't want spyware neither bloatware, I got Linux installed and asked for a refund of the OEM license. After a little of talking, they were wanting to charge me US$100 (to remove the license, which I already had wiped, as I got FDE Linux installed) to refund US$70 of the OEM license. This year, wondering to buy a new Acer notebook, I asked them again if they would refund me the OEM license without all the hassle (as they did pay me the US$70, without me having to pay the US$100).
