[$] 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 windows.php.net 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.

[$] 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.

Six new stable kernels

[$] Linux Mint drops Ubuntu Snap packages

Wednesday 8th of July 2020 04:46:34 PM
The Linux Mint project has made good on previous threats to actively prevent Ubuntu Snap packages from being installed through the APT package-management system without the user's consent. This move is the result of "major worries" from Linux Mint on Snap's impact with regard to user choice and software freedom. Ubuntu's parent company, Canonical, seems open to finding a solution to satisfy the popular distribution's concerns — but it too has interests to consider.

The "Open Usage Commons" launches

Wednesday 8th of July 2020 02:53:58 PM
Google has announced the creation of the Open Usage Commons, which is intended to help open-source projects manage their trademarks. From the organization's own announcement: "We created the Open Usage Commons because free and fair open source trademark use is critical to the long-term sustainability of open source. However, understanding and managing trademarks takes more legal know-how than most project maintainers can do themselves. The Open Usage Commons is therefore dedicated to creating a model where everyone in the open source chain – from project maintainers to downstream users to ecosystem companies – has peace of mind around trademark usage and management. The projects in the Open Usage Commons will receive support specific to trademark protection and management, usage guidelines, and conformance testing." Initial members include the Angular, Gerrit, and Istio projects.

Sandboxing in Linux with zero lines of code (Cloudflare blog)

Wednesday 8th of July 2020 02:36:54 PM
The Cloudflare blog is running an overview of sandboxing with seccomp(), culminating in a tool written there to sandbox any existing program. "We really liked the 'zero code seccomp' approach with systemd SystemCallFilter= directive, but were not satisfied with its limitations. We decided to take it one step further and make it possible to prohibit any system call in any process externally without touching its source code, so came up with the Cloudflare sandbox. It’s a simple standalone toolkit consisting of a shared library and an executable. The shared library is supposed to be used with dynamically linked applications and the executable is for statically linked applications."

[$] Hugo: a static-site generator

Tuesday 7th of July 2020 11:28:40 PM
Static web-site generators take page content written in a markup language and render it into fully baked HTML, making it easy for developers to upload the result and serve a web site simply and securely. This article looks at Hugo, a static-site generator written in Go and optimized for speed. It is a flexible tool that can be configured for a variety of use cases: simple blogs, project documentation, larger news sites, and even government services.

[$] Sleepable BPF programs

Tuesday 7th of July 2020 05:20:16 PM
When support for classic BPF was added to the kernel many years ago, there was no question of whether BPF programs could block in their execution. Their functionality was limited to examining a packet's contents and deciding whether the packet should be forwarded or not; there was nothing such a program could do to block. Since then, BPF has changed a lot, but the assumption that BPF programs cannot sleep has been built deeply into the BPF machinery. More recently, classic BPF has been pushed aside by the extended BPF dialect; the wider applicability of extended BPF is now forcing a rethink of some basic assumptions.

[$] Home Assistant improves performance in 0.112 release

Monday 6th of July 2020 05:23:13 PM
The Home Assistant project has released version 0.112 of the open-source home automation hub we have previously covered, which is the eighth release of the project this year. While previous releases have largely focused on new integrations and enhancements to the front-end interface, in this release the focus has shifted more toward improving the performance of the database. It is important to be aware that there are significant database changes and multiple potential backward compatibility breaks to understand before attempting an upgrade to take advantage of the improvements.

Kernel prepatch 5.8-rc4

Monday 6th of July 2020 03:54:28 AM
The 5.8-rc4 kernel prepatch is out for testing. "The end result is that it's been fairly calm, and there's certainly been discussion of upcoming fixes, but I still have the feeling that 5.8 is looking fairly normal and things are developing smoothly despite the size of this release."

Book: Perl 7: A Risk-Benefit Analysis

Friday 3rd of July 2020 06:32:31 PM
Dan Book has done a detailed analysis of the Perl 7 transition. "Large amount of CPAN modules will not work in Perl 7; plans for working around this would either involve every affected CPAN author, which is a virtual impossibility for the stated 1 year time frame; or the toolchain group, a loose group of people who each maintain various modules and systems that are necessary for CPAN to function, who either have not been consulted as of yet or have not revealed their plans related to the tools they maintain. Going into this potential problem sufficiently would be longer than this blog post, but suffice to say that a Perl where highly used CPAN modules don't seamlessly work is not Perl."

[$] Netflix releases open-source crisis-management tool

Friday 3rd of July 2020 03:01:23 PM
Earlier this year, Netflix developed and released a new Apache-licensed project named Dispatch. It is designed to coordinate the response to and the resolution of security-related incidents, but the project aims for more than just that. Rather, it hopes to be valuable for any type of one-off incident that needs coordination across an organization, such as a service outage.

Open source is more than code: Developing Red Hat Satellite documentation upstream

The code base for Satellite begins upstream and moves downstream. Until recently, the Satellite documentation did not follow the same journey. In this post, I will outline what has been happening with Satellite documentation over the last year and how this benefits both the Foreman community and Red Hat Satellite users. The Foreman and Katello projects are the upstreams of Red Hat Satellite. The discussions and contributions that take place in the vibrant upstream community help shape the Red Hat Satellite code base. Red Hat’s open source and community strategy has made Red Hat Satellite a robust and flexible product that can manage complex management workflows. Read more

Android Mirroring App ‘Scrcpy’ Improves Shortcuts, Clipboard Support

Scrcpy v1.15 picks up the ability to forward ctrl and shift keys to your handset. Why is that useful? Because it means you can now use familiar keyboard shortcuts on your device in apps that support them, e.g., ctrl + t to open a new browser tab in a browser. This nifty addition is also able to pass ctrl + c and ctrl + v to Termux, if you use it. It also supports text selection easier using shift + → and similar. With the ctrl key now in use for shortcuts Scrcpy now uses the left alt or left super key as its shortcut modifier. Don’t like this? It can be changed. Read more
