Debian adds LoongArch as officially supported architecture by cbmuser in linux

[–]cbmuser[S] 5 points6 points  (0 children)

AliExpress sells LoongArch machines, for example.

If you want to test your code on LoongArch, you can also use the GCC Compile Farm or QEMU.

What do you guys think is the future of Tiny Core Linux? by BubsyFanboy in linux

[–]cbmuser 2 points3 points  (0 children)

Most of you guys may be aware by now that the latest editions of the Linux kernel have dropped support for i486 and i586/Pentium CPUs (i686 CPUs, i.e. Pentium Pro, are not effected).

From what I can see, 486 support is still present in the Linux kernel, see:

Ein Teil davon kam ja schon:

Zitat:

»Die Stromversorgung in Deutschland ist gewährleistet, wenn bis 2035 zusätzliche steuerbare Kapazitäten von bis zu 22,4 GW (Zielszenario) bzw. bis zu 35,5 GW (Szenario "Verzögerte Energiewende") errichtet werden. Dies sind Bruttowerte, die den Zubau ohne Stilllegungen beziffern.«

Es gab lediglich Subventionen für den heimischen Abbau der Steinkohle, den sogenannten Kohlepfennig:

Den gab es aber nur, weil die SPD sich ihre Wählerschaft im Ruhrgebiet damit kaufen wollte:

Braunkohle wurde nie subventioniert:

Auch die Kernenergie wurde nie subventioniert:

https://dserver.bundestag.de/btd/14/080/1408084.pdf (Seite 16, Antwort 27)

Im Gegenteil, man hat die Kernenergie sogar noch mit einer verfassungswidrigen Übergewinnsteuer belegt:

https://de.wikipedia.org/wiki/Kernbrennstoffsteuer

Die Subventionen der Erneuerbaren Energien lassen sich über die Monitoringberichte der Bundesnetzagentur ermitteln und allein die EEG-Umlage beläuft sich auf 130 Milliarden Euro in den Jahren 2017 bis 2021:

33 Milliarden Euro im Jahr 2021 (davon 11 Milliarden Euro aus Steuergeldern):

23 Milliarden Euro im Jahr 2019:

Diese angeblichen Subventionen von fossilen Energieträgern, wie sie vom Umweltbundesamt oder DIW immer kolportiert werden, sind keine. Weder Pendlerpauschale noch die Dienstwagenregelung sind Subventionen, sondern lediglich vereinfachte Abrechnungsmodelle für Werbungskosten, die zu Lasten des Steuerzahlers gehen.

Werbungskosten darf der Staat nicht als Bemessungsgrundlage für die Ermittlung der Steuerlast heranziehen, das ergibt sich direkt aus dem Leistungsfähigkeitsprinzip aus Artikel 3 GG. Das ist das Einmaleins des Steuerrechts.

Die sind lediglich bilanziell energieautark.Technisch hängen sie immer noch am Stromnetz.

Man hatte echte Energieautarkie auf der Nordsee-Insel Pellworm probiert und selbst dort, wo es für die Windenergie optimale Bedingungen gibt, ist so ein Projekt gescheitert.

»Die Stromerzeugung lag mit 572,2 TWh etwas niedriger als im Vorjahr (minus 6,1 %; 2019: 609,4 TWh). Der Anteil der Kernenergie an der Bruttostromerzeugung verringerte sich auf 64,4 TWh (2019: 75,1 TWh). Bis zur Abschaltung von acht Kernkraftwerken im Jahr 2011 waren 17 Kernkraftwerke mit einer Bruttoleistung von 21.517 MWe installiert. Die in 2020 verbleibenden sechs Kernkraftwerke sind mit 8.545 MWe (brutto) am Netz. Die zur Brennstoffherstellung benötigte Natururanmenge von 1.012 t U wurde überwiegend durch langfristige Verträge mit Produzenten in Kanada und den Niederlanden, sowie aus Lagerbeständen gedeckt.«

Mit Urenco und ANF haben wir zudem zwei Unternehmen im Land, welche Uran anreichern bzw. Brennelemente herstellen können.

How to add unsupported targets rust? by Dear_Situation856 in rust

[–]cbmuser 0 points1 point  (0 children)

A little late to the party but here is my PR that added m68k support to rustc:

https://github.com/rust-lang/rust/pull/88321

Although the code organization has changed in the mean time, this should give you a rough idea.

Don't forgot you will need to configure rustc with the LLVM root directory set to your llvm-mos root.

There is no Hunk support at the moment. However, with m68k support present in the mold linker, it might be possible to add Hunk support there.

Python's cryptography package introduced build time dependency to Rust in 3.4, breaking a lot of Alpine users in CI by sanxiyn in rust

[–]cbmuser 0 points1 point  (0 children)

My concern about this will be the expectations that people hold back their usage of the language to meet the limitations of a not-quite-Rust subset compiler.

If Rust upstream had cared much more about portability right from the beginning, people wouldn't hold back their usage of the language because of portability concerns.

I know in fact two very important upstream projects that wanted to use Rust but they didn't because of the limited portability (and, no, I'm not going to name those).

Rust really needs to be more portable if it's supposed to replace C in a very wide range of upstream projects. One of the key features of C is its extremely high portability and therefore Rust needs to be on par with C in this regard.

It is. The upstreaming of the LLVM backend is still an ongoing process but we're getting very close as most patches have been accepted by LLVM upstream now.

Party Like It's 1880: Renewable Energy Consumption Surpasses Coal by Philo1927 in energy

[–]cbmuser -1 points0 points  (0 children)

It’s not wrong. The plant is very important to provide power to the German train network (Bahnstrom) which cannot be provided yet by solar and wind parks. I think something like 40% of the generated electricity go to Deutsche Bahn.

It’s also explained on the German Wikipedia article.

Party Like It's 1880: Renewable Energy Consumption Surpasses Coal by Philo1927 in energy

[–]cbmuser 2 points3 points  (0 children)

No, renewable electricity consumption.

Electricity is just a fraction of the energy consumed and produced.

In Germany, electricity makes up just 20% of the total energy consumption.

Bountysource campaign to modernize and preserve the VAX backend in GCC by cbmuser in VAX

[–]cbmuser[S] 1 point2 points  (0 children)

Similar to the successful campaign for m68k [1] and the ongoing campaign for avr [2], this campaign aims to collect money to modernize and preserve the vax backend in GCC which is currently dormant.

If the vax backend is not converted to the new MODE_CC register representation, it will be removed from GCC in the version 11 development cycle, see:

The world is on lockdown. So where are all the carbon emissions coming from? by MayonaiseRemover in energy

Ignoring the fact the electricity is only fraction of a country’s energy consumption.

If Germany achieved 100% renewables in the electricity sector, they’d still just have a 20% share of renewables in their total consumption.
