Announcing Tumbleweed Snapshots

Monday 27th of November 2017 04:06:21 PM
The newly announced openSUSE "Tumbleweed snapshots" feature is an attempt to make rolling distributions a little easier for those who don't want to stay on the leading edge all the time. In essence, it keeps a snapshot of the state of the distribution at regular intervals and enables users to install applications from their particular snapshot. That allows the installation of new applications without the need to drag in everything else that may have changed since the system as a whole was updated. "Tumbleweed Snapshots provides the best of both worlds, the latest packages when you want them and the one package you need in the middle of working on a project."

Several companies clarify GPL enforcement policies

Monday 27th of November 2017 03:24:22 PM
Here is a press release from Red Hat on GPL enforcement: "To provide greater predictability to users of open source software, Red Hat, Facebook, Google and IBM today each committed to extending the GPLv3 approach for license compliance errors to the software code that each licenses under GPLv2 and LGPLv2.1 and v2." This is, in effect, a reiteration of the approach to enforcement recently adopted by many kernel developers, but it extends to all GPLv2-licensed software contributed by those companies.

Kernel prepatch 4.15-rc1

Monday 27th of November 2017 01:24:33 AM
The 4.15-rc1 kernel prepatch is out. "So it's been the usual two weeks of merge window, and rc1 is out. And that normal time length is about the only thing usual about this merge window. Because of the indiscriminate mass slaughter of turkeys in the US last week, lots of people - including me - were on vacation. That meant that I had asked for people to try to make the merge window front-heavy, but it also meant that then during the second week I was rather more strict than usual in what I pulled."

Stable kernel updates

Friday 24th of November 2017 04:12:30 PM
Greg Kroah-Hartman has released stable kernels 4.14.2, 4.13.16, 4.9.65, 4.4.101, 4.4.102, and 3.18.84. This is the last 4.13.y kernel and users should upgrade to 4.14 now. For the two 4.4 updates Greg says: "[4.4.102] is a bugfix for an issue if PAGE_POISONING is enabled in the kernel configuration. If you do not run your kernel with that option, no need to upgrade, just stick with 4.4.101."

7 tools for analyzing performance in Linux with bcc/BPF (

Wednesday 22nd of November 2017 04:37:45 PM
Brendan Gregg introduces a set of BPF-based tracing tools on "Traditional analysis of filesystem performance focuses on block I/O statistics—what you commonly see printed by the iostat(1) tool and plotted by many performance-monitoring GUIs. Those statistics show how the disks are performing, but not really the filesystem. Often you care more about the filesystem's performance than the disks, since it's the filesystem that applications make requests to and wait for. And the performance of filesystems can be quite different from that of disks! Filesystems may serve reads entirely from memory cache and also populate that cache via a read-ahead algorithm and for write-back caching. xfsslower shows filesystem performance—what the applications directly experience."

[$] Replacing x86 firmware with Linux and Go

Monday 20th of November 2017 07:07:18 PM

The Intel Management Engine (ME), which is a separate processor and operating system running outside of user control on most x86 systems, has long been of concern to users who are security and privacy conscious. Google and others have been working on ways to eliminate as much of that functionality as possible (while still being able to boot and run the system). Ronald Minnich from Google came to Prague to talk about those efforts at the 2017 Embedded Linux Conference Europe.

I have seen it many times. "Linux is a cancer". "Open sauce". "Linuxtard". I even remember the teacher who did not bring a laptop for her presentation and, when I offered her my Linux netbook, she rejected it as if I had presented her something illegal. She tried to use an old Windows computer instead but, when the computer failed, she ended up displaying her presentation with my Linux netbook. Clearly, this teacher's position was not based on ignorance or lack of expertise because she knew Linux existed and all she had to do was to display slides. Her refusal was due to indoctrination: she had learned that Linux and non-Microsoft office suites had to be rejected. Read more

Tryton and Python Deprecation Warnings

  • Trying Tryton
    The quest to find a free-software replacement for the QuickBooks accounting tool continues. In this episode, your editor does his best to put Tryton through its paces. Running Tryton proved to be a trying experience, though; this would not appear to be the accounting tool we are searching for. Tryton is a Python 3 application distributed under the GPLv3 license. Its home page mentions that it is based on PostgreSQL, but there is support for MySQL and SQLite as well. Tryton, it is said, is "a three-tier high-level general purpose application platform" that is "the core base of a complete business solution providing modularity, scalability and security". The "core base" part of that claim is relevant: Tryton may well be a solid base for the creation of a small-business accounting system, but it is not, out of the box, such a system itself.
  • Who should see Python deprecation warnings?
    As all Python developers discover sooner or later, Python is a rapidly evolving language whose community occasionally makes changes that can break existing programs. The switch to Python 3 is the most prominent example, but minor releases can include significant changes as well. The CPython interpreter can emit warnings for upcoming incompatible changes, giving developers time to prepare their code, but those warnings are suppressed and invisible by default. Work is afoot to make them visible, but doing so is not as straightforward as it might seem. In early November, one sub-thread of a big discussion on preparing for the Python 3.7 release focused on the await and async identifiers. They will become keywords in 3.7, meaning that any code using those names for any other purpose will break. Nick Coghlan observed that Python 3.6 does not warn about the use of those names, calling it "a fairly major oversight/bug". In truth, though, Python 3.6 does emit warnings in that case — but users rarely see them.
