@C_for_Crazy @zack_overflow No. It. Is. Not. I got a laptop 3x faster on paper than my desktop, but because of work policies I couldn't disable Defender, it compiles & links 3x slower. Microsoft then had to invent a whole "Dev Drive" mechanism as the antidote. (Lets AV run more async.) Now they run similar.

@zack_overflow That's not a Windows issue. Windows Defender is pretty lightweight compared to third party alternatives and is reliable for almost all tasks. Kernel level anti cheat software is not from Microsoft.

How each OS deals with malware Linux: nothing it's a skill issue macOS: we'll just ask a lot if you really want to run that thing Windows: download this kernel-level software that intercepts every system call, network packet, filesystem operation and makes your PC 10x slower

@splendid_pete This DHS? youtube.com/shorts/fsI9Txi… Hope she didn't peer too closely at their work ;-)

When did right-wing Americans become so fucking retarded? I’m trying to pinpoint when it started.

@abneribeiro0 @ccallac7 You won't sell Java to game devs (for good reasons: latency and 6x memory usage). But for other cases you get best of both worlds: instant compiles, robust refactoring, easy multi-platform support => good DX. Plus can AOT compile to native for fast(er) runtime. Great all-rounder.

@ccallac7 And in those examples, where does Java fit in?

A good programmer only needs to know two languages: One for making high quality, high performance software (ex. C/C++) And one for quickly hacking together prototypes and simulations (ex. Python)

@grok @HorrisVR @Rothmus Half right - I said % Europeans & total tax not marginal: those paying 55% is not "many". Someone earning millions after tax can invest to grow wealth EXPONENTIALLY. Folk with such wealth ACCELERATING up won't be THAT burdened by ANY constant-relative level of marginal tax.

Clarification: Denmark's marginal tax rate reaches 55.9% on income over DKK 665k (~$97k USD), affecting roughly the top 10-15% of earners—not 0.0002%. Effective 55% requires ~DKK 10.3M (~$1.5M USD), top 0.1%. High rates (>50%) exist in multiple EU nations like France (55.4%) and Austria (55%). The meme reflects reality for many Europeans.

@grok @HorrisVR @Rothmus So the correct answer to "is this a total lie?" is YES for the UK and YES for all but 0.0002% of the richest EU ctizens, earning over $160,000,000/year (not bad) in ONE country, a country which BTW is generally happy to pay a higher tax for a better society. Thanks for playing.

@ldubox @HorrisVR @Rothmus For a Danish resident (2025 rates, average municipal tax, no church tax), a gross salary of ~DKK 10.3 million yields an effective tax rate of 55%. This income level places them in the top 0.1% of earners.

@grok @HorrisVR @Rothmus @grok what salary would someone in Denmark need to earn to pay an effective total tax rate of 55.0%, and what percentile of earners would that person be?

For an England resident with £100k gross salary (2025/26 rates): - Income tax: £27,432 - Employee NI: £4,011 - Total: £31,443 (31.4% effective) This places them in the 96th percentile of UK earners (top 4%), per latest ONS data. Note: Marginal rate jumps above £100k due to allowance tapering.

@grok @HorrisVR @Rothmus But @grok you're talking only about the top tax bracket, ignoring for example the 0% bottom bracket. How much total tax including NI would an England resident earning a quoted salary of 100k GBP/year pay? And what percentile of earners would that person be?

UK residents do not pay a flat 55% income tax rate. In England, the top rate is 45% (+2% NI = 47% effective). In Scotland, it's up to 48% (+2% NI = 50%). However, in the £100k–£125k band, tapering of the personal allowance creates effective rates up to 62% (England) or 69.5% (Scotland). The meme likely refers to countries like Denmark (55.9%). Not a total lie for Europe, but overstated for UK.

@SebAaltonen And so are we - the digestive system processes food on the exterior of our body, before allowing those nutrient goodnesses in.

A straw is just a non-uniformly scaled long doughnut (100x scale in Y-direction). Both have a single hole.

@alina_yurenko @graalvm I know the year is 2025, but... Will this make compiling Swing desktop applications to native easier? Huh? Huh?! 👀

We are working on a new big project for @GraalVM — Project Crema: github.com/oracle/graal/i…. It will lift Native Image's default closed-world assumption by allowing dynamic loading and execution of classes at run time. Stay tuned for updates!

@markcojuangco @patbahn @AukeHoekstra @arbmacip For the reasons experts like Auke research and quantify. He's not being a "hardass" for ideological reasons - but by economic & environmental analysis. Last I looked (and I am but a spectator) new nuclear seemed reasonable in very specific locations, but those are shrinking fast.

A milestone: by my calculations Russia has now received $1 trillion in payments for fossil fuel since they started the war in Ukraine. The world will be better off when we move to solar+wind.

@splendid_pete @FM_Szijjarto Yup & not just gas... - 2014 Russia finances 80% of nuclear power expansion, repayments start 2031. Some details of the deal remain state secrets - 2016..2024 wind turbines banned within 12km(!) of a residence (leaving only 2-6% of land) - EVs subsidised Lock-in tactics?

@FM_Szijjarto Ukraine didn’t put you in a difficult situation, you spineless piece of shit, you put us Hungarians in a difficult situation by sucking up to Russia.

Bulgaria is building a new gas pipeline, to which Hungary is connected via Romania. This comes at a time when Ukraine has put us in a difficult situation by cutting off routes. We are grateful to Bulgaria, a reliable partner, w/ 21 million m³ gas arriving daily via the Balkans.

@AlanNeveu @alex_avoigt 😆 Top marks go to the AI! But queries were inspired by a comment a friend made once... "if folks would get to see the volume of petrol a car holds in a bathtub..." (then they'd have a better intuition about it)

@ldubox @alex_avoigt A+

This can't be repeated often enough A BEV consumes about 160 kg of 🔋 battery cell materials over its lifetime. And at the end of life 70% - 90% is recovered. An ICE burns through 17,000 liters of fuel. Gone. No recovery. No recycling. Just burned into the atmosphere.

@AlanNeveu @alex_avoigt Topping up with petrol (adding 1/3 of a bathtub each time), for 340 times over a car's lifetime, adds 39 tons of pure CO2 to the atmosphere (which fills 9 Olympic swimming pools). Considering that CO2 is only 400 parts per million (ppm) of air, this is... a lot.

@alex_avoigt We Americans have no point of reference for comparing a kilogram with a liter.

@tito @alex_avoigt Good Q. I originally thought it meant just the metals. But it could be that the diagram compares all "consumed" materials, assuming the other 70% battery material is recycled (which seems a reasonable figure). 160 / 0.3 => 533 kg.

@alex_avoigt Isn't a battery more like 600-700kg? Point still stands but trying to understand the 160kg

RIP American AI industry. According to a recent study by the Paulson Institute (archivemacropolo.org/interactive/di…), 38% of the top-tier AI talent working in the US are Chinese, more than Americans themselves.

@SebAaltonen 😍Sweet! Simple guy here, I'm happy for now with our 2020 Leaf, but charging on trips away does suck. Can usually find a working, available Chademo & get 45kW. But for Plan B (AC) it accepts only 1-phase, so 22kW becomes 6 kW Stoooopid choices for the EU. Why, Nissan, why?

The new Mercedes CLA pricing was announced in Finland. The RWD model is 49900€, only 4.5k€ more than the Tesla Model 3. Specs: - 792km WLTP range - 320kW fast charging (800V) - Super efficient: 12.2 kWh/100km, cd=0.21, two gear gearbox AWD version range is 770km (+10k€).

In a functuoning democracy, everybody is equal under the law, and a president doesn't get to persecute those that will not be bullied. This is closer to what historically has been classified as fascism. That's not hyperbole. That's proper scientific classification.

@isharduld And according to Grok since 2007: flagship desktop CPUs are 50x faster, while corresponding memory bandwidth is "only" 9x faster & latency halved. So the issues are even more pronounced today! (My prompts requested considering memory-limited vs non-memory limited benchmarks.)

Opinions on this? takeaway for me - Your code isn’t slow, your memory access is

@KuittinenPetri @SebAaltonen That % profit level can hardly be called a "margin"! But I'll accept "gross".😁

Moore's law is not dead. But the competition has been severely hampered by the "chip" war (2018-) sanctions. USA has successfully coerced all of its key allies not to: a) manufacture too advanced chips for Chinese companies (Note: Nvidia/Apple/AMD etc. are also fabless and TSMC makes their chip) b) don't sell advanced chip making equipment, software etc. to China either. Without these restrictions the Chinese would have entered the market with razor thin margins and pushed down the prices significantly. Now Nvidia has very little competition, which is unhealthy for the market in general, bad for gamers and AI industry. Nvidia's recent gross profit margin has been quite high, reaching 74.99% for the quarter ending January 31, 2025.

Modern day graphics: 5060 matches 4060 Ti matches 3070. Long gone are the days when xx60 series used to match the previous generation xx80. Half the price for the same performance. Is Moore's law finally dead?

@the_antrik @petergresham @grok @JessePeltan I agree! 25y is a better basis. So halve the numbers, how does the math work out? Have to say grok's "research" here differs a bit from my first queries, but still you have to REALLY cherry-pick the worst scenario to make the 1-time cost of a panel a bad environmental choice

@petergresham @grok @ldubox @JessePeltan Bullshit. Panels are usually specified for 25 year lifetime, but they generally do last longer in the field.

There are NO RARE EARTH ELEMENTS in silicon solar panels or lithium ion batteries.
