A new LibreOffice strategic marketing plan

Wednesday 15th of July 2020 10:09:57 PM
LWN recently covered the effort within the LibreOffice project to find ways to support the companies doing the bulk of the development work. The project has now posted a revised marketing plan [PDF] with a number of changes, including the removal of the "personal edition" name. Regarding LibreOffice Online: "Following our normal development process, the Ecosystem will release their own versions in their own timing, allowing some features to reach their Enterprise versions before they are subsequently shipped in TDF builds (this allows the Ecosystem to positively differentiate by contributing new features & functionality)".

Ubuntu Will No Longer Track Which Packages Users Install (OMG! Ubuntu!)

Wednesday 15th of July 2020 09:57:25 PM
The OMG! Ubuntu! site reports that the Debian "popularity contest" application is being removed from Ubuntu. "But with Snaps, Flatpaks, PPAs and other avenues giving developers more direct ways to market to users (not to mention more accurate numbers on how many people use their software) the relative merits of 'what's popular in the repos' is …Well, a touch moot."

[$] What's new in Lua 5.4

Wednesday 15th of July 2020 08:19:29 PM
Lua version 5.4 was released at the end of June; it is the fifteenth major version of the lightweight scripting language since its creation in 1993. New in 5.4 is a generational mode for the garbage collector, which performs better for programs with lots of short-lived allocations. The language now supports "attributes" on local variables, allowing developers to mark variables as constant (const) or resources as closeable (close). There were also significant performance improvements over 5.3 along with a host of minor changes.

OpenSUSE board non-confidence effort fails

Wednesday 15th of July 2020 03:43:41 PM
The openSUSE board troubles that LWN reported on in March have continued to simmer, and the promised election for an empty seat has not yet been held. During this time, instead, the project has voted on a petition to declare a lack of confidence in the board as a whole, a result that would have forced the election of an entirely new board. In the end, the number of votes fell far short of the number required, and the existing board will move forward with the election plan.

[$] Operations restrictions for io_uring

Wednesday 15th of July 2020 12:25:28 AM
The io_uring subsystem is not much over one year old, having been merged for the 5.1 kernel in May 2019. It was initially added as a better way to perform asynchronous I/O from user space; over time it has gained numerous features and support for functionality beyond just moving bits around. What it has not yet gained is any sort of security mechanism beyond what the kernel already provides for the underlying system calls. That may be about to change, though, as the result of this patch set from Stefano Garzarella adding a set of user-configurable restrictions to io_uring.

Security updates for Tuesday

Tuesday 14th of July 2020 02:49:34 PM
Security updates have been issued by Fedora (mingw-podofo and python-rsa), openSUSE (LibVNCServer, mozilla-nss, nasm, openldap2, and permissions), Red Hat (dovecot, sane-backends, and thunderbird), Scientific Linux (dbus), and SUSE (firefox and thunderbird).

[$] Managing tasks with Org mode and iCalendar

Tuesday 14th of July 2020 12:53:56 AM
In an earlier article, guest author Martin Michlmayr reviewed the todo.txt and Taskwarrior task managers. This article continues the process of examining task managers by looking at tools for Org mode, which is a system originally created for Emacs, as well as at tools that make use of the iCalendar standard. It is time to find out whether he can find a system that meets his needs.

Kernel prepatch 5.8-rc5

Monday 13th of July 2020 01:10:33 PM
The 5.8-rc5 kernel prepatch is out for testing; it's a relatively large set of changes. "Maybe I'm in denial, but I still think we might hit the usual release schedule. A few more weeks to go before I need to make that decision, so it won't be keeping me up at night."

[$] Microsoft drops support for PHP

Saturday 11th of July 2020 12:25:11 AM
For years, Windows PHP users have enjoyed builds provided directly by Microsoft. The company has contributed to the PHP project in many ways, with the binaries made available on being the most visible. Recently Microsoft Project Manager Dale Hirt announced that, beginning with PHP 8.0, Microsoft support for PHP on Windows would end.

[$] Creating open data interfaces with ODPi

Friday 10th of July 2020 05:53:26 PM
Connecting one source of data to another isn't always easy because of different standards, data formats, and APIs to contend with, among the many challenges. One of the groups that is trying to help with the challenge of data interoperability is the Linux Foundation's Open Data Platform initiative (ODPi). At the 2020 Open Source Summit North America virtual event on July 2, ODPi Technical Steering Committee chairperson Mandy Chessell outlined the goals of ODPi and the projects that are part of it. She also described how ODPi is taking an open-source development approach to make data more easily accessible.

Security updates have been issued by Fedora (curl, LibRaw, python-pillow, and python36), Mageia (coturn, samba, and vino), openSUSE (opera), and Ubuntu (openssl).

[$] LibreOffice: the next five years

Thursday 9th of July 2020 03:29:21 PM
The LibreOffice project would seem to be on a roll. It produces what is widely seen as the leading free office-productivity suite, and has managed to move out of the shadow of the moribund (but brand-recognized) Apache OpenOffice project. The LibreOffice 7 release is coming within a month, and the tenth anniversary of the founding of the Document Foundation arrives in September. Meanwhile, LibreOffice Online is taking off and, seemingly, seeing some market success. So it is a bit surprising to see the project's core developers in a sort of crisis mode while users worry about a tag that showed up in the project's repository.

    This report was written by Apurva Nandan as part of Google Summer of Code 2020. This blog post is in continuation of GSoC Reports: Benchmarking NetBSD, first evaluation report blog and describes my progress in the second phase of GSoC 2020 under The NetBSD Foundation. In this phase, I worked on the automation of the regression suite made using Phoronix Test Suite (PTS) and its integration with Anita. The automation framework consists of two components Phoromatic server, provided by Phoronix Test Suite in pkgsrc, and Anita, a Python tool for automating NetBSD installation.

  • Interest in Kodi Declines After a Turmultuous Few Years of Piracy Headlines

    After many years of being mentioned in the same breath as movie and TV show piracy, interest in the Kodi media player appears to have peaked and is now on the decline.

Programming Leftovers

  • RcppSimdJson 0.1.1: More Features

    A first update following for the exciting RcppSimdJson 0.1.0 release last month is now on CRAN. Version 0.1.1 brings further enhancements such direct parsing of raw chars, working with compressed files as well as much expanded querying ability all thanks to Brendan, some improvements to our demos thanks to Daniel as well as a small fix via a one-liner borrowed from upstream for a reported UBSAN issue. RcppSimdJson wraps the fantastic and genuinely impressive simdjson library by Daniel Lemire and collaborators. Via very clever algorithmic engineering to obtain largely branch-free code, coupled with modern C++ and newer compiler instructions, it results in parsing gigabytes of JSON parsed per second which is quite mindboggling. The best-case performance is ‘faster than CPU speed’ as use of parallel SIMD instructions and careful branch avoidance can lead to less than one cpu cycle use per byte parsed; see the video of the talk by Daniel Lemire at QCon (also voted best talk).

  • Jonathan Dowland: Generic Haskell

    When I did the work described earlier in template haskell, I also explored generic programming in Haskell to solve a particular problem. StrIoT is a program generator: it outputs source code, which may depend upon other modules, which need to be imported via declarations at the top of the source code files. The data structure that StrIoT manipulates contains information about what modules are loaded to resolve the names that have been used in the input code, so we can walk that structure to automatically derive an import list. The generic programming tools I used for this are from Structure Your Boilerplate (SYB), a module written to complement a paper of the same name.

  • 9 reasons I upgraded from AngularJS to Angular

    In 2010, Google released AngularJS, an open source, JavaScript-based frontend structure for developing single-page applications (SPAs) for the internet. With its move to version 2.0 in 2016, the framework's name was shortened to Angular. AngularJS is still being developed and used, but Angular's advantages mean it's a smart idea to migrate to the newer version.

  • Vivaldi Explains Why They Make "Proprietary Garbage"

    It is unfair to say that Vivaldi is not open source at all as someone like Distrotube has done, the way the company behind Vivaldi has decided to handle this application is by using a dual licensing system where the open source portion of the application is licensed under an open source BSD license but that's not the point of today, the point is to explain why they have decided to license their software in such a way.

  • Scientists Forced To Change Names Of Human Genes Because Of Microsoft's Failure To Patch Excel

    Six years ago, Techdirt wrote about a curious issue with Microsoft's Excel. A default date conversion feature was altering the names of genes, because they looked like dates. For example, the tumor suppressor gene DEC1 (Deleted in Esophageal Cancer 1) was being converted to "1-DEC". Hardly a widespread problem, you might think. Not so: research in 2016 found that nearly 20% of 3500 papers taken from leading genomic journals contained gene lists that had been corrupted by Excel's re-interpretation of names as dates. Although there don't seem to be any instances where this led to serious errors, there is a natural concern that it could distort research results. The good news is this problem has now been fixed. The rather surprising news is that it wasn't Microsoft that fixed it, even though Excel was at fault. As an article in The Verge reports:
