Maakuth··on Trinity keeps KDE 3 on life support
Trolltech, whose main product Qt was, was listed in Oslo stock exchange from 2006 to the Nokia acquistion of 2008.
Maakuth··on Trinity keeps KDE 3 on life support
Digia actually spun it off and Qt again is an independent publicly traded company. I suppose KDE community is the place to start looking for Qt open source resources.
Maakuth··on Business Booms and Depressions Since 1775 (1943)
Could be! Adam Tooze's book about the Nazi regime's finances was a good read and there were details about this, but I might have misremembered (https://www.goodreads.com/book/show/711592.The_Wages_of_Dest...).
Maakuth··on Business Booms and Depressions Since 1775 (1943)
Germany defaulted on some of the payments and France responded to that by occupying Ruhr (https://en.wikipedia.org/wiki/Occupation_of_the_Ruhr). That took out a substantial portion of Germany's production capacity, but they were mandated to keep paying the reparations. The German state tried to keep up with that by printing money, triggering hyperinflation and paving way to the Nazi regime.
Maakuth··on Germany solar power output jumps to record highs
Nuclear operators try to minimize losses of the shutdown by not replacing parts that are still workable until the shutdown. When you know of the impending shutdown, you can plan for the plant to be as EOL as possible. If you plan for long term use, parts are replaced gradually so that there's no big revamp pending.
Maakuth··on Germany solar power output jumps to record highs
That's very impressive amount of solar capacity, but the nameplate power is not super useful measure in solar, as the capacity factor for solar is somewhere between 10-15% in Germany, while for nuclear it's more like 90%. To get rid of fossil fuels in Germany, a ton of natgas heating would need to be replaced with electric heat pumps, driving up the power consumption during winter. Solar hardly produces any energy during the winter.

I don't think the parent's criticism was limited to the last three closures, but the whole fleet that was shut down starting 2011.
Maakuth··on Monitoring energy usage with smart plugs, Prometheus and Grafana
They call it HAN here in Finland too, but it's the same interface as the Netherlands one.

This applies to Finland and Sweden too, perhaps others to follow.

That's just it - these are no more customizable than real buttons! They come with preprinted symbols for their function, so no cost advantage of customization.

Maakuth··on DiskClick: Ever wanted to hear old hard drive sounds
I believe the recommendation is to run btrfs on top of mdraid, which works fine. Meta is said to use btrfs, but apparently they don't care about the raid implementation, so there's nobody paying for that development.

OpenZFS works fine, but it can be tricky to install due to the license thing, not all distributions support it in their installer.

Bcachefs is said to be the up and coming contender for both, but it was merged to the mainline kernel in January, so probably at the moment it is tricky to install as well. I would think many of this year's distribution releases will make it available.

Maakuth··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
Are spot electricity contracts available, so that you can do it like that? Makes sense then. And of course the installation cost of battery is way smaller than for a PV plant as no roof work is required.
Maakuth··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
At least a rooftop PV installation breaks even* here in Finland with scarce sun and cheap power. Batteries are not there yet. If you don't need the battery as a UPS, I would wait still a few years before going for a home battery.

*: Easily half of the cost is the installation labor. If you can DIY at least parts of it, you can get decent ROI.

Maakuth··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
Very good points. I do think the grid battery capacity being added this year is going to be mostly li-ion.
Maakuth··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
Pumped storage is a type of grid storage, but I don't think TFA includes it in battery storage. Pumped storage is a fine technology, but is there a lot of build potential left for it?
Maakuth··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
I guess I earned the snark for not mentioning the batteries.

Weirdly the news item doesn't tell what sort of energy storage capacity these battery installation have, only the peak power output of 14.3 GW for this year's addition. While that is certainly a gigantic addition no matter what the energy capacity of these battery installations is going to be, running the whole grid on batteries over the periods of low renewable generation is going to require still orders of magnitude more batteries. I suppose there's enough lithium in the ground for this, but elastic demand and dispatchable generation are probably going to be part of the equation for economical reasons.

Maakuth··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
Of course those capacity factors hide one important bit, the dispatchability. While the capacity factor is the same in this list for wind and hydro, the wind and solar generation are naturally capped by nature. When demand exceeds the natural availability of these, you need to dispatch some extra generation. Hydro and natural gas are well suited for this, coal can do it even if dirtily. Nuclear generation could be made dispatchable, but due to the essentially zero marginal cost of running it all the time instead of limiting generation, it seldom is used in this fashion.

Electricity demand could be elastic too, but there's a limit to that. It's not always feasible to limit or shut down industrial processes for the few hours of expensive power. And home consumers are loath to not use their stoves when they want. There's potential in elastic demand though.

Maakuth··on Reverse engineering a forgotten 1970s Intel dual core beast: 8271 (2020)
I believe this is one of the insights Steve Wozniak had that allowed them to make Apple // hardware a lot simpler and cheaper than the competition. They implemented this sort of stuff in the operating system.

Commodore had these complicated chips too - for example the 1541 disk drive had the same 6502 CPU as the C64! They were able to compete on the price in the 80s by the virtue of owning their chief chip supplier, MOS Techonology.

There's TOTP support in Keepass2Android and KeepassXC (and surely other Keepass implementations too). These are open source and you can control how the password database is kept: cloud storage is supported as well as local file (that you can sync with Syncthing or whatnot).
Maakuth··on Volkswagen Will Bring Back Physical Buttons in New Cars
This VW solution really is worst of both worlds, as these are capacitive surfaces with printed symbols. So you cannot really iterate on them post-release.
Maakuth··on Submarine Cable Map 2023
No idea of what precise sort of hardware is there, but the fact is that these cables consist of a bunch of fibers. Dozens of them typically, quick search suggests up to 144, but I doubt that's a physical ceiling. So I suppose they make a branch when needed, with some number of fibers going to another direction.

Maakuth··on U.S. reenters the nuclear fuel game
Yes, I believe MOX is one option of what you can make from what's left from reprocessing. I think it's possible to make more conventional fuel there too, but then what are you going to do with the plutonium.
Maakuth··on U.S. reenters the nuclear fuel game
Those are breeder reactors. In breeders, less fissile materials are transformed into more fissile ones. That's interesting technology and very nice on paper, but there are practical challenges.

Reprocessing is another thing entirely. It relies on the fact that used nuclear fuel is mainly not reusable due to accumulation of neutron poisons. In reprocessing, these poisons are removed so that the rest of the fuel can be reused. This too has many practical challenges as you end up with liquid radioactive materials and a lot of it is waste. So far it has proven more practical than breeders, though. Perhaps that is because the same processes can be used to extract materials for nuclear weapons.

Maakuth··on In Defense of Electricity Markets
More cross-border capacity would help with reliability as well as making the investments' profitability easier to estimate. This is something Europe at least is investing in.
