2017 Maintainer and Kernel Summit planning

sze, 2017-06-14 17:58
The Kernel Summit is undergoing some changes this year; the core developers' gathering from previous events will be replaced by a half-day "maintainers summit" consisting of about 30 people. The process of selecting those people, and of selecting topics for the open technical session, is underway now; interested developers are encouraged to submit their topic ideas.

[$] Assembling the history of Unix

sze, 2017-06-14 17:52
The moment when an antique operating system that has not run in decades boots and presents a command prompt is thrilling for Warren Toomey, who founded the Unix Heritage Society to reconstruct the early history of the Unix operating system. Recently this historical code has become much more accessible: we can now browse it in an instant on GitHub, thanks to the efforts of a computer science professor at the Athens University of Economics and Business named Diomidis Spinellis.

Click below (subscribers only) for a look at the Unix Heritage Society and what it has accomplished.

[$] A survey of scheduler benchmarks

sze, 2017-06-14 16:52
Many benchmarks have been used by kernel developers over the years to test the performance of the scheduler. But recent kernel commit messages have shown a particular pattern of tools being used (some relatively new), all of which were created specifically for developing scheduler patches. While each benchmark is different, having its own unique genesis story and intended testing scenario, there is a unifying attribute; they were all written to scratch a developer's itch.

Elixir Cross Referencer: new way to browse kernel sources

sze, 2017-06-14 01:16
Free electrons has released the initial version of the Elixir Cross-Referencer, a Linux source code cross-referencing online tool. Elixir uses a new engine written in Python that replaces LXR, the engine used in free electron's previous online tool. "Another reason that motivated a complete rewrite was that we wanted to provide an up-to-date reference (including the latest revisions) while keeping it immutable, so that external links to the source code wouldn’t get broken in the future. As a direct consequence, we would need to index many different revisions for each project, with potentially a lot of redundant information between them. That’s when we realized we could leverage the data model of Git to deal with this redundancy in an efficient manner, by indexing Git blobs, which are shared between revisions. In order to make sure queries under this strategy would be fast enough, we wrote a proof-of-concept in Python, and thus Elixir was born."

Firefox 54 released

k, 2017-06-13 23:05
Firefox 54.0 has been released. The release notes are somewhat sparse, however this blog post contains more information about some changes under-the-hood. "To make Firefox run even complex sites faster, we’ve been changing it to run using multiple operating system processes. Translation? The old Firefox used a single process to run all the tabs in a browser. Modern browsers split the load into several independent processes. We named our project to split Firefox into multiple processes ‘Electrolysis (E10S)’ after the chemical process that divides water into its core elements. E10S is the largest change to Firefox code in our history. And today we’re launching our next big phase of the E10S initiative."

4.12-rc5 kernel prepatch has been released

h, 2017-06-12 19:41
The 4.12-rc5 prepatch is out; it is rather larger than others in this cycle, Linus Torvalds said. "It's not like rc5 is *huge*, but it definitely isn't the nice and small one I was hoping for. There's nothing in [particular] that looks very worrisome, and it may well just be random timing - the rc sizes do fluctuate a lot depending on just which subsystem gets synced up that particular rc, and we may just have hit that "everybody happened to sync up this week" case."

[$] A beta for PostgreSQL 10

p, 2017-06-09 22:23

PostgreSQL version 10 had its first beta release on May 18, just in time for the annual PGCon developer conference. The latest annual release comes with a host of major features, including new versions of replication and partitioning, and enhanced parallel query. Version 10 includes 451 commits, nearly half a million lines of code and documentation, and over 150 new or changed features since version 9.6. The PostgreSQL community will find a lot to get excited about in this release, as the project has delivered a long list of enhancements to existing functionality. There's also a few features aimed at fulfilling new use cases, particularly in the "big data" industry sector.

Announcing Rust 1.18

p, 2017-06-09 01:35
Version 1.18 of the Rust programming language has been released. "One of the largest changes is a long time coming: core team members Carol Nichols and Steve Klabnik have been writing a new edition of “The Rust Programming Language”, the official book about Rust. It’s being written openly on GitHub, and has over a hundred contributors in total. This release includes the first draft of the second edition in our online documentation. 19 out of 20 chapters have a draft; the draft of chapter 20 will land in Rust 1.19."

G'MIC 2.0

p, 2017-06-09 00:43
G'MIC is a generic, extensible framework for image processing, often used as a plug-in for GIMP. Version 2.0 has been released. "One of the major new features of this version 2.0 is the re-implementation of the plug-in code, from scratch. The repository G’MIC-Qt developed by Sébastien (an experienced member of the team) is a Qt-based version of the plug-in interface, being as independent as possible of the widget API provided by GIMP." The announcement has much more details about G'MIC and how it can be used. LWN looked at G'MIC in August 2014.

[$] Language summit lightning talks

cs, 2017-06-08 00:34

Over the course of the day, the 2017 Python Language Summit hosted a handful of lightning talks, several of which were worked into the dynamic schedule when an opportunity presented itself. They ranged from the traditional "less than five minutes" format to some that strayed well outside of that time frame—some generated a fair amount of discussion as well. Topics were all over the map: board elections, beta releases, Python as a security vulnerability, Jython, and more.

[$] Status of mypy and type checking

cs, 2017-06-08 00:03

In his 2017 Python Language Summit session, Jukka Lehtosalo updated attendees on the status of type checking for the language, in general, and for the mypy static type checker. There are new features in the typing module and in mypy, as well as work in progress and planned features for both. For a feature, type hints, that is really only around three years old, there has been a lot of progress made—but, of course, there is still more to come.
