Stable kernels 5.2.8, 4.19.66, and 4.14.138

Friday 9th of August 2019 05:58:42 PM
Greg Kroah-Hartman has announced the release of three new stable kernels: 5.2.8, 4.19.66, and 4.14.138. As usual, the kernels contain important fixes, so users should upgrade.

[$] Akaunting: a web-based accounting system

Friday 9th of August 2019 04:31:27 PM
One of these years, LWN will have a new accounting system based on free software. That transition has not yet happened, though, despite the expending of a fair amount of energy into researching alternatives. Your editor recently became aware of a system called Akaunting, so a look seemed worthwhile. This tool may have the features that some users want, but it seems clear that your editor's quest is not done yet.

A Kubernetes security assessment

Friday 9th of August 2019 04:12:23 PM
The Kubernetes community has posted the extensive results [PDF] of a security assessment performed earlier this year. "Overall, Kubernetes is a large system with significant operational complexity. The assessment team found configuration and deployment of Kubernetes to be non-trivial, with certain components having confusing default settings, missing operational controls, and implicitly defined security controls. Also, the state of the Kubernetes codebase has significant room for improvement. The codebase is large and complex, with large sections of code containing minimal documentation and numerous dependencies, including systems external to Kubernetes. There are many cases of logic re-implementation within the codebase which could be centralized into supporting libraries to reduce complexity, facilitate easier patching, and reduce the burden of documentation across disparate areas of the codebase."

The Document Foundation announces LibreOffice 6.3

Thursday 8th of August 2019 06:00:11 PM
The Document Foundation has announced the release of LibreOffice 6.3. This new version of the free-software office suite has lots of new features, better performance, and more interoperability with proprietary formats. In particular, documents can now be redacted to hide sensitive information before they are shared or exported, there are user-interface changes to make it more compact and easier to work with, a FOURIER function has been added to Calc, editable PDFs can be designed more easily, multiple improvements have been made in the Microsoft Office format handling, and more. Beyond that: "Writer and Calc performance has been improved by an order of magnitude based on documents provided by end users: text files with different bookmarks, tables and embedded fonts, large ODS/XLSX spreadsheets, and Calc files with VLOOKUP load and render more quickly. Saving Calc spreadsheets as XLS files is also faster."

[$] Grand Schemozzle: Spectre continues to haunt

Thursday 8th of August 2019 03:08:33 PM
The Spectre v1 hardware vulnerability is often characterized as allowing array bounds checks to be bypassed via speculative execution. While that is true, it is not the full extent of the shenanigans allowed by this particular class of vulnerabilities. For a demonstration of that fact, one need look no further than the "SWAPGS vulnerability" known as CVE-2019-1125 to the wider world or as "Grand Schemozzle" to the select group of developers who addressed it in the Linux kernel.

Linux Journal ceases publication

Thursday 8th of August 2019 03:16:34 AM
It is with sadness that we report that Linux Journal has ceased publication. The magazine announced its demise at the end of 2017, then was happily reborn in early 2018, but apparently that was not to last. Editor Kyle Rankin posted "An Awkward Goodbye" on August 7. "After dying and being revived, it was finally starting to look like some day soon we would be able to walk on our own. Unfortunately, we didn't get healthy enough fast enough, and when we found out we needed to walk on our own strength, we simply couldn't. So here we are giving our second, much more awkward, goodbye. What happens now? We gave each other a proper hug during the first goodbye, do we hug again this time? Do we do the hand-shake-that-turns-into-a-single-arm-hug thing? Do we just sort of wave and smile?" LJ will be missed.

[$] Mozilla's WebThings Gateway now available for Turris Omnia router

Wednesday 7th of August 2019 10:03:23 PM
The "Web of Things" (WoT) is meant as a way to enable Internet of Things (IoT) devices to appear on the web. Mozilla's entry into the WoT world is the WebThings project, which consists of both a Framework API and a Gateway software distribution to host applications. On July 25, the project announced the Gateway 0.9 release with support for the Turris Omnia wireless home router.

[$] Escape sequences in Python strings

Wednesday 7th of August 2019 07:07:40 PM
A change for Python 3.8—currently in beta—has produced some user-visible warnings, but the problem is often in code that a user cannot (or should not) change: third-party modules. The problem that the warning is trying to highlight is real, however. The upshot is that the handling of escape sequences (or non escape sequences, in truth) in Python string literals is in a rather messy state at this point.

FSFE releases the REUSE 3.0 copyright/licensing specification

Wednesday 7th of August 2019 04:57:32 PM
The Free Software Foundation Europe has an announcement about the release of the REUSE 3.0 specification. "The licensing of a software project is critical information. Developers set the terms under which others can reuse their software, from individuals to giant corporations. Authors want to make sure that others adhere to their chosen licenses; potential re-users have to know the license of third-party software before publication; and companies have to ensure license compliance in their products that often build on top of existing projects. The REUSE project, led by the Free Software Foundation Europe (FSFE), helps all of these parties."

Knoll: Technical vision for Qt 6

Wednesday 7th of August 2019 02:12:27 PM
Lars Knoll describes the goals for the next major version of the Qt graphics toolkit. "Qt has been growing a lot over the last years, to the point where delivering a new version of it is a major undertaking. With Qt 6 there is an opportunity to restructure our product offering and have a smaller core product that contains the essential frameworks and tooling. We will use the market place to deliver our add-on frameworks and tools, not as a tightly coupled bundle with the core Qt product."

[$] Racket: Lisp for learning

Tuesday 6th of August 2019 10:52:50 PM
Lisp is one of the oldest programming languages still in use today—Fortran is older by a year, but the Lisp community (or communities) seems to be the more dynamic of the two. In any case, the Lisp landscape has a lot of nooks and crannies to explore; I recently ran into a dialect that I had not encountered before: Racket. That may simply reflect ignorance on my part, but, while I was introduced to Lisp (too) many moons ago, I had not really paid it much mind until I sat in on a talk about Lisp at earlier this year. Something about Racket caught my eye, so I did some poking around to see what it is all about.

FFmpeg 4.2 released

Tuesday 6th of August 2019 10:03:28 PM

[$] The Compact C Type Format in the GNU toolchain

Tuesday 6th of August 2019 06:42:26 PM
The Compact C Type Format (CTF) is a way of representing information about a binary program; it can be seen as a simpler alternative to the widely used DWARF format. While CTF has been around for some years, it has not seen much use in the Linux world. According to Elena Zannoni, who talked about CTF at the 2019 Open Source Summit Japan, that situation may be about to change; work is underway to bring CTF support to the GNU tools shipped universally with Linux systems.

Red Hat Enterprise Linux 7.7 released

Tuesday 6th of August 2019 02:53:11 PM
Red Hat has announced the release of Red Hat Enterprise Linux 7.7. "Beyond new capabilities, Red Hat Enterprise Linux 7.7 also marks the transition of Red Hat Enterprise Linux 7 to Maintenance Phase I within the Red Hat Enterprise Linux 10-year lifecycle. Maintenance Phase I emphasizes maintaining infrastructure stability for production environments and enhancing the reliability of the operating system. Future minor releases of Red Hat Enterprise Linux 7 will now focus solely on retaining and improving this stability rather than net-new features."

Save Web Pages As Single HTML Files For Offline Use With Monolith (Console)

Monolith is a command line tool to save any web page as a single HTML file that contains everything needed to render web page locally, without needing a working Internet connection. Use this to save web pages containing documentation, wiki articles, and anything else that interests you, for local/offline use. Since the web pages are saved in plain HTML, use a tool that can search in files to quickly find the web page you're looking for. Unlike the regular "Save page as" (or Ctrl + s) option provided by web browsers to save web pages to your computer, which saves web page assets in a folder next to the saved web page, this command line tool retrieves the web page assets and converts them into base64 data URLs, using that in the document instead of the regular URLs. As a result, page assets like Javascript, CSS or images are embedded in the page HTML, so all you need is a web browser to access the locally saved web page. Read more
