qsdf38100··on Lawsuits test Tesla claim that drivers are solely responsible for crashes
This "Full Self Driving" thing is absurd. It should already be illegal to sell "Self Driving" cars that are 0% responsible for any crash. But Elon thought it wasn’t enough and decided to go Full Hypocrisy and called it "Full Self Driving". What a joke.
qsdf38100··on Jeff Lawson buys The Onion
You just used "extreme", "left" and "leftist" 7 times in 4 sentences. Sounds a bit "extreme" and "biased" to me.
qsdf38100··on The Performance Impact of C++'s `final` Keyword
"Inlining is actually pretty evil".

No it's not. Except if you __force_inline__ everything, of course.

Inlining reduces the number of instructions in a lot of cases. Especially when things are abstracted and factored with lot of indirections into small functions that calls other small functions and so on. Consider a 'isEmpty' function, which dissolves to 1 cpu instruction once inlined, compared with a call/save reg/compare/return. Highly dynamic code (with most functions being virtual) tend to result in a fest of chained calls, jumping into functions doing very little work. Yes the stack is usually hot and fast, but spending 80% of the instructions doing stack management is still a big waste.

Compilers already have good heuristics about when they should be inlining, chances are they are a lot better at it than you. They don't always inline, and that's not possible anyway.

My experience is that compiler do marvels with inlining decisions when there are lots of small functions they _can_ inline if they want to. It gives the compiler a lot of freedom. Lambdas are great for that as well.

Make sure you make the most possible compile-time information available to the compiler, factor your code, don't have huge functions, and let the compiler do its magic. As a plus, you can have high level abstractions, deep hierarchies, and still get excellent performances.

You created a new account just to post this overly positive review?
qsdf38100··on An open source initiative to share and compare heat pump performance data
Are all the compared heat pumps working at the same temperature levels? Otherwise, the COP isn't a good comparison metric, as even for an ideal heat pump with a COP = 1 / carnot_efficiency, it depends on the temperatures.

For instance, a heat pump lifting heat from 20°C to 100°C with a COP of "only" 2 is excellent, whereas lifting heat from 20°C to 30°C with a cop of 3 is not impressive.

qsdf38100··on Spreadsheets are all you need
They are portable, but the displayed function names are translated depending on the local. Same as comma vs dots.
qsdf38100··on Scientific journal publishers and editors say they are being offered bribes
When the money goes to the employee of the institution providing the benefit instead of the institution itself.
qsdf38100··on Converting the Kernel to C++
Won’t you end up with mostly _unsafe_ code this way?
qsdf38100··on Hyperloop One to shut down
Not even trying to hide his disgusting business tactics. Casually, openly admitting it was to waste hundred of millions of investments. And people are still going to defend him because, rockets, and cars from the future, and success! He’s like trump, he knows people will follow regardless of what he does.
qsdf38100··on Hyperloop One to shut down
He did it to divert investment into high speed trains, which have the potential to significantly reduce the number of Teslas he could hope to sell.

He successfully made investors waste hundreds of millions into these hyperloop startups, which are like real life parody of high-tech scam startups.

On the other hand, one must be quite illiterate scientifically to buy into Musks grand sci-fi projects. Should only work on 5 years old. But you don’t have to believe, you just have to pretend and take these easy millions from rich but dumb VCs.

qsdf38100··on EU opens proceedings against X over efforts to combat information manipulation
Why the /s ? You actually said the truth, but it seems you aren’t aware.
qsdf38100··on EU opens proceedings against X over efforts to combat information manipulation
Yeah but be careful what you wish for. Constructive criticism is good, shitting on the EU and parroting "EU is a corrupt dictatorship!!" propaganda will make foreign-backed populists rise. Who will benefit from the downfall of th EU? Why are so many people seemingly happy about it?
qsdf38100··on EU opens proceedings against X over efforts to combat information manipulation
Yeah, everyone shits on the EU, like "the EU is actually worst than [insert random dictatorship]", yet there are more people trying to emigrate to EU than ever.

Even inside EU, people shit on the EU. My take is that people in EU and in the west generally are bored/ashamed with their easy lives, they want to be badass, not to have it easy. So they live in a fictional universe where they are actually persecuted. "We have no freedom of speech!! We live in a dictatorship". But deep down it's all pretending, no one want to actually emigrate from EU to Russia. Even Russians, whenever enough money is around, well, you can be sure the children of wealthy oligarchs are living in London, Paris, Bruxel, enjoying free speech, freedom, healthcare, schools, but somehow, still shitting on the EU...

qsdf38100··on EU opens proceedings against X over efforts to combat information manipulation
Why are you so happy with eu downfall? Are they too woke? Too weak? Who are you cheering for instead?
qsdf38100··on EU opens proceedings against X over efforts to combat information manipulation
Crazy how this site becomes anti-anything any time Elon or any of his business gets criticized. Thanks to Elon, Twitter has turned into a disinformation-as-a-service platform for maga and foreign actors. But the eu should just watch its population be turned into conspiracy following zombies, and do nothing?

Hmmm, I wonder who benefits from this.

qsdf38100··on EU opens proceedings against X over efforts to combat information manipulation
You can criticize the eu, but pretending everything is at the same level is either ignorance or bad faith.
qsdf38100··on The new Paris métro
I own an iPhone. It’s as buggy as Microsoft products. In the end, Microsoft products are Okay. The reason people criticize Microsoft is politics. First you decide which side is the right one (that’s easy, it’s Linux) and then you use Bad Faith to make the wrong side look as bad as possible.
qsdf38100··on Why do people still use VBA?
Vba has "on error goto".
qsdf38100··on My experience taking Tesla to court about FSD
You’re completely right, misleading people to make money is not a mistake from musk, it’s his job, he’s very good at it, and he indeed is shielded from any consequences since any crash while using "Full" Self Driving is still fully the driver’s fault.
qsdf38100··on YouTube's Ad Blocker Crackdown Spurs Record Uninstalls
I got several ads from a well known scammer, full of conspiracy bullshit about how school is a way for the "elites" to hide some grand truth from the masses. It promotes his "re education" portal, which is actually a get-rich-fast type of scam, à la Andrew Tate.

I reported the ad, twice, but YT claims it doesn’t violate any policies. I’m pretty sure it violates EU laws about disinformation, but no one is going to listen to me right ?

qsdf38100··on SpaceX Starship Super Heavy Project at the Boca Chica Launch Site
For humanity, really? So he cares about humans? Human rights? He values life?

He seems to care for future humans, current humans can suffer, it doesn’t matter because everything will be so great in 100 years. But wait, maybe it won’t be so great because another great leader will disregard current humans, for humanity?

qsdf38100··on Chomsky explains why nobody is a moral relativist
Regardless of whether it's true or not, the fact that this is what he has to say about this invasion is what I find troublesome. Is it so hard to condemn it? Sounds like a diversion, to get away with not condemning it. But he doesn't have to choose, it's just bad faith. How long will we hear "but, what about Hiroshima?" any time a dictator goes for a land grab?
qsdf38100··on What it takes to pass a file path to a Windows API in C++
Wrong. Windows uses UTF-16. It used to use UCS-2 a long time ago.
qsdf38100··on Neuralink is recruiting subjects for the first human trial
What makes you think he will succeed?

I’m still waiting for any sort of progress towards the hyperloop. Not to mention "Full" self driving, or Mars colonies. Last time I heard of Neuralink, they butchered hundreds of animals for no apparent progress.

qsdf38100··on A terawatt of solar module capacity expected within 16 months
We need orders of magnitude more storage to go full solar, or wind. Currently it’s hard for electric network management to integrate even 10% of intermittent energy sources into the mix.
qsdf38100··on Why Socialism? (1949)
I'm basically saying neo-liberal capitalism, as in minimum-regulation capitalism, is unfair. You're right that it's about having capital already, not about being fit. Anyway, I think the law of the fittest is awful, so I'm not defending neo-liberal capitalism, quite the contrary.

Anywhere you have money and trade, you will have wealthy people, using their wealth to get unfair advantages over poor people, and get even wealthier. I don't care if it fits your definition of capitalism, even though I think it does. My point is that you can fight it, or embrace it, but it's going to emerge, and you won't eradicate it. So, instead of describing this naturally emerging thing as pure evil, let's try to make it fair, have regulations to protect consumers, taxes to redistribute wealth and prevent too much wealth accumulation. That's what I would like "socialism" to mean.

Being a billionaire is absolutely not my goal in life, not even a desire. Billionaires actually are lonely people, stuck in a very restricted social circle. They can't have normal friends. Ask minecraft's creator.

Please don't assume I'm a brainwashed wannabee-billionaire defending my "Capitalist" overlords. I would be better placed to assume you're the typical anti-system guy that thinks "Capitalism" is the root of all evil, and that sees everything in this light.

qsdf38100··on Why Socialism? (1949)
I said that socialism is an _attempt_. I certainly agree that it can fail and produce misery.

I'd like to define socialism as a moderate regulation of capitalism. Like, capitalism with the right balance of regulations (so industries aren't free to wreck the environment, risk people lives, etc), cheap/free social services/health care and taxing the wealthy more than the poor.

Then I could say I'm for socialism. Now a lot of "socialist" countries are dictatorships and/or heavily corrupt states. So I... don't know. I guess I'm a centrist then?

qsdf38100··on Why Socialism? (1949)
Any time I hear "Capitalism is [...]", it is when one forces his own, carefully worded definition, so that the subsequent arguments sound natural, logic, simple, irrefutable. "It's simply the system of exploitation".

Let me try that game. Capitalism is what emerges from trade and money. You can fight it, you can embrace it, but you won't eradicate it. Black markets and barter will emerge, which are forms of capitalism. In the end, all you can do is regulate it (or not). Then I would define socialism as an attempt to regulate it so it doesn't turn into the law of the fittest.

qsdf38100··on How would you say “She said goodbye too many times before.” in Latin?
Are you sure? My understanding is that the two words are the full sentence.

Édit: I mean in the last paragraph of the answer.

qsdf38100··on Rust 1.72.0
Me? mad? Hmmm.

What about your language? And his?

"Bitching", "baffling", "rage-baiting trolls", "completely wrong", "literally doesn't matter".

My language: "in my experience", "more often than not", "I'd like to be wrong and happened to have came across mostly bad apples."

So, I'm not the one who is "mad" and "bitching" here. You are the one mad at me.

Who is being tricked? Sounds like you are tricking yourself.
