[Meme] Linux is Becoming a Code ‘Burial Ground’, Sometimes at the Expense of Size and Complexity (Bloat)

Posted in GNU/Linux, Kernel at 7:20 am by Dr. Roy Schestowitz

What ASF and Linux Foundation also became (place to shelve struggling corporate projects)

Sidious mask: Linux. The new Windows?

Summary: Code that not many people are interested in (and which may in fact be obsolete and undesirable for patent/monopoly reasons) is being dumped or tucked into Linux; the sheer magnitude — and the growing concern about the ramifications this entails — was explained below by Con Kolivas, who developed a bunch of Linux schedulers (now MuQSS)

Last Wednesday/Thursday:

  • More delays and motivation issues

    It’s fair to say that my motivation for keeping up with linux kernel development has been flagging for some time now and the current world situation is not helping. Hearing the news extol the virtues of linux-5.8 being the “biggest release ever” does not particularly aid my situation.

    [...]

    As time goes on and more and more features get added to the scheduler that have nothing to do with ordinary desktop and mobile platform usage, at some stage distributions will be tempted to become dependent on one or more of those features and if I don’t develop MuQSS much further to incorporate my own version of those features, it will become redundant. Given the completely different scheduler architecture of MuQSS versus CFS means I can’t simply just port over the code most of the time; I have to write my own complete feature equivalent version and these are far from trivial. The accounting code is completely different, most of the CGROUP features aren’t even implemented, and deadline scheduling is not available at all for example. If more of these appear in the future and eventually become showstoppers, then unless some miracle happens to make me find the motivation to work on them, it will be the death of it.

  • MuQSS/CK’s Con Kolivas Becoming Concerned Over The Increasing Size Of The Linux Kernel

    Longtime independent Linux kernel developer Con Kolivas known for his work previously on the BFS scheduler and now the MuQSS scheduler as well as his out-of-tree “-ck” patch set is becoming increasingly concerned over the growing size of the kernel code-base and that ultimately could put an end to his work with a focus on greater desktop interactivity/performance.

    Kolivas stopped contributing to the mainline Linux kernel a decade ago but has continued maintaining the “-ck” patch-set for each new kernel release as well as working on the likes of the Brain Fuck Scheduler and Multiple Queue Skiplist Scheduler. Generally he’s been quite punctual in re-basing the work for new kernel releases aside from when the retired anaesthesiologist took a break earlier this year to design equipment for the COVID-19 battle. But now his latest battle is the increasing size of the Linux kernel that often brings core infrastructure changes as opposed to just new drivers.

  2. [Meme] Team UPC Congratulating Itself

    The barrage of fake news and misinformation about the UPC deliberately leaves out all the obvious and very important facts; even the EPO‘s António Campinos and Breton (Benoît Battistelli‘s buddy) participated in the lying

  4. The Demonisation and Stereotyping of Coders Not Working for Big Corporations (or 'The System')

    The war on encrypted communication (or secure communications) carries on despite a lack of evidence that encryption stands in the way of crime investigations (most criminals use none of it)



  5. On the 'Peak Hacker' Series

    Hacker culture, unlike Ludditism, is ultimately a movement for justice, for equality, and for human rights through personal and collective emancipation; Dr. Farnell has done a good job explaining where we stand and his splendid series has come to a close

  10. A Parade of Fake News About the UPC Does Not Change the General Consensus or the Simple Facts

    European Patents (EPs) from the EPO are granted in violation of the EPC; Courts are now targeted by António Campinos and the minions he associates with (mostly parasitic litigation firms and monopolists), for they want puppets for “judges” and for invalid patents to be magically rendered “valid” and “enforceable”



  11. Welcome to 2022: Intentional Lies Are 'Benefits' and 'Alternative Facts'

    A crooks-run EPO, together with the patent litigation cabal that we’ve dubbed ‘Team UPC’ (it has nothing to do with science or with innovation), is spreading tons of misinformation; the lies are designed to make the law-breaking seem OK, knowing that Benoît Battistelli and António Campinos are practically above the law, so perjury as well as gross violations of the EPC and constitutions won’t scare them (prosecution as deterrence just isn’t there, which is another inherent problem with the UPC)



  12. From Software Eating the World to the Pentagon Eating All the Software

    “Software is eating the world,” according to Marc Andreessen (co-founder of Netscape), but the Empire Strikes Back (not the movie, the actual empire) by hijacking all code by proxy, via Microsoft, just as it grabbed a lot of the world’s communications via Skype, bypassing the world's many national telecoms; coders need to fight back rather than participate in racist (imperial) shams such as GitHub

  17. Computer Users Should be Operators, But Instead They're Being Operated by Vendors and Governments

    Computers have been turned into hostile black boxes (unlike Blackbox) that distrust the person who purchased them; moreover, from a legislative point of view, encryption (i.e. computer security) is perceived and treated by governments like a threat instead of something imperative — a necessity for society’s empowerment (privacy is about control and people in positions of unjust power want total and complete control)



  18. Peak Code — Part I: Before the Wars

    Article/series by Dr. Andy Farnell: "in the period between 1960 and 2060 people had mistaken what they called "The Internet" for a communications system, when it had in fact been an Ideal and a Battleground all along - the site of the 100 years info-war."

    In Gemini (or the Web as seen through Gemini clients such as Kristall) the user comes first; it's not sites/capsules that tell the user how pages are presented/rendered, as they decide only on structural/semantic aspects



  22. The Future of Techrights

    Futures are difficult to predict, but our general vision for the years ahead revolves around more community involvement and less (none or decreased) reliance on third parties, especially monopolistic corporations, mostly because they oppress the population via the network and via electronic devices

    Misinformation/disinformation in so-called 'news' sites is a pandemic which spreads; in the process, the founder of GNU/Linux gets defamed and GNU/Linux itself is described as the problem, not the solution to the actual problems
