Coghlan: The Python packaging ecosystem

szo, 2016-09-17 13:55
Here's a lengthy piece from Nick Coghlan on how Python software gets to users. "There have been a few recent articles reflecting on the current status of the Python packaging ecosystem from an end user perspective, so it seems worthwhile for me to write-up my perspective as one of the lead architects for that ecosystem on how I characterise the overall problem space of software publication and distribution, where I think we are at the moment, and where I'd like to see us go in the future."

Bash 4.4 and Readline 7.0 released

p, 2016-09-16 23:22
The GNU Bourne Again SHell (Bash) project has released version 4.4 of the tool. It comes with a large number of bug fixes as well as new features:"The most notable new features are mapfile's ability to use an arbitrary record delimiter; a --help option available for nearly all builtins; a new family of ${parameter@spec} expansions that transform the value of `parameter'; the `local' builtin's ability to save and restore the state of the single-letter shell option flags around function calls; a new EXECIGNORE variable, which adds the ability to specify names that should be ignored when searching for commands; and the beginning of an SDK for loadable builtins, which consists of a set of headers and a Makefile fragment that can be included in projects wishing to build their own loadable builtins, augmented by support for a BASH_LOADABLES_PATH variable that defines a search path for builtins loaded with `enable -f'. The existing loadable builtin examples are now installed by default with `make install'." In addition, the related Readline command-line editing library project has released Readline 7.0.

Hutterer: Synaptics pointer acceleration

p, 2016-09-16 13:57
For this week's development horror story, it would be hard to do better than Peter Hutterer's quest to figure out how pointer acceleration works in the Synaptics driver. "Also a disclaimer: the last time some serious work was done on acceleration was in 2008/2009. A lot of things have changed since and since the server is effectively un-testable, we ended up with the mess below that seems to make little sense. It probably made sense 8 years ago and given that most or all of the patches have my signed-off-by it must've made sense to me back then. But now we live in the glorious future and holy cow it's awful and confusing."

[$] Backports and long-term stable kernels

sze, 2016-09-14 22:26
One of the longest running debates in the kernel community has to do with the backporting of patches from newer kernels to older ones. Substantial effort goes into these backports, with the resulting kernels appearing in everything from enterprise distributions to mobile devices. A recent resurgence of this debate on the Kernel Summit discussion list led to no new conclusions, but it does show how the debate has shifted over time.

Kügler: LTS releases align neatly for Plasma 5.8

sze, 2016-09-14 19:07
Sebastian Kügler reports that Plasma 5.8 will be the first LTS release of the Plasma 5 series. "One great thing of this release is that it aligns support time-frames across the whole stack from the desktop through Qt and underlying operating systems. This makes Plasma 5.8 very attractive for users need to that rely on the stability of their computers." Plasma 5.8 will receive at least 18 months of bugfix and security support from upstream KDE.

Apache NetBeans Incubator Proposal

k, 2016-09-13 20:39
Geertjan Wielenga posted a proposal to the Apache incubator list to adopt NetBeans, an open source development environment, tooling platform, and application framework. "NetBeans has been run by Oracle, with the majority of code contributions coming from Oracle. The specific reason for moving to Apache is to expand the diversity of contributors and to increase the level of meritocracy in NetBeans. Apache NetBeans will be actively seeking new contributors and will welcome them warmly and provide a friendly and productive environment for purposes of providing a development environment, tooling environment, and application framework."

Tridgell: ArduPilot and DroneCode

k, 2016-09-13 14:31
Andrew "Tridge" Tridgell writes about the ArduPilot project's withdrawal from the Dronecode group. "Unfortunately DroneCode has a built-in flaw. The structure and bylaws of DroneCode are built around exceptional power for the Platinum members, giving them extraordinary control over the future of DroneCode. [...] Just how great a flaw that is has been shown by the actions of the Platinum members over the last two months. Due to their overwhelming desire to be able to make a proprietary autopilot stack the Platinum members staged what can only be called a coup. They removed all top level open source projects from DroneCode, leaving only their own nominees in the Technical Steering Committee. They passed a resolution requiring that all projects hand over control of all trademarks, accounts and domains to their control."

Abbott: Success with Interns

szo, 2016-09-10 00:16

Laura Abbott marks the end of the latest round of open-source internships at Outreachy with a blog post reflecting on "what makes an internship successful," especially as seen in the kernel team's internships. Among Abbott's lessons: "Choose your tasks carefully. Tasks with a specific goal but multiple ways to solve are best. Too open ended tasks can be frustrating for all involved but there should be some chance for decision making. Just giving a list of tasks and exactly how they should be completed isn't good for learning. Give your intern a chance to propose a solution and then review it together." Also: "Speaking of review, code review is a skill. Model how to respond to code review comments. Encourage interns to practice reviewing others code and ask questions as well." That is just a sampling; in total, Abbott lists well over a dozen take-aways from the experience, all worth reading.
