xpl··on The Truth About H-1B Visas It's wage theft, pure and simple
> People can jump employers while one H1B

Good luck finding a new employer willing to sponsor your H1B within just 60 days (the grace period allowed before self-deportation) in this job market.

Additionally, switching employers resets your green card approval process (if it has started), which can take years. This serves as a significant disincentive to change employers unless you've already filed your I-485. Considering that an H1B worker has only 6 years to progress through this process, there is even more pressure to avoid changing employers.

> MAGA decisively won

Did they? Trump just recently made a couple of statements, siding with Musk on that issue. He has no other choice, as money comes from Elon, not from MAGA.

He also reversed his stance on EVs during his campaign, openly admitting that he had to due to Elon's contributions. So basically, Elon is the president now.

I was responding to the comment regarding "how about the top 0.1%". H-1B isn't designed for bringing the 0.1%, there are other visas that already do exactly that. Also, it is not so high bar, I know people even without a degree who got O1, it isn't even a requirement. But you need to have a public track record of various kinds.

Also, I am not against visas intended to fill labor shortages. But it needs to be done in a way that incentivizes hiring local talent over foreign. Currently the H-1B works the other way around. This has to be dealt with. Like raising the minimum salary, making it significantly more expensive to hire an H-1B worker than a local one, and removing the exploitative leverage employers have over visa holders — people shouldn't have to fear negotiating for better terms due to the threat of deportation. That would likely fix it.

Nobody here is anti-immigration.

The reality is that the H1B program is being used not to bring in individuals with 130+ IQ, but essentially anyone with a bachelor's degree, which can be easily obtained from diploma mills. In some third-world countries, you can even buy your degree outright.

For the top 0.1%, there are O1 visas, as well as EB1 and EB2-NIW visas — the latter two don't even require an employer and can be self-sponsored. Plus, they grant you a green card, unlike the H1B, which ties you to an employer.

However, to qualify for these visas, you need to demonstrate that you're genuinely valuable to the U.S. They are designed for top-tier entrepreneurs, engineers, scientists, and artists with a verifiable track record. These visas can also be gamed, but it's much harder than with the H1B program.

Looking at discussions about the current dire state of the white-collar job market — with thousands of applications per job posting and many months of job hunting, even for individuals with over 10 years of experience — it's hard to argue that we're not currently oversupplied.

Perhaps it's time to reconsider the "supply" side of the equation and do something with H1B.

xpl··on Trump sides with Musk on support for H-1B visas for foreign tech workers
Yes, and you can fulfill this growing demand by raising wages, which is essentially the market mechanism to bring in additional supply. Another way to address this is by importing cheaper labor from abroad.

For American workers, it is better to let wages rise than to import foreign labor (which would ultimately suppress wage growth).

Therefore, importing labor does suppress wages — as you've essentially demonstrated yourself.

xpl··on Trump sides with Musk on support for H-1B visas for foreign tech workers
This argument doesn't hold because you don't know how much an average American SWE would be making today if there were no H1Bs — it could be $200k.

> because there aren't enough qualified workers in the US

It's often not a shortage of skills but a shortage of pay.

Companies can also invest in growing local talent. There are tons of STEM graduates who cannot find jobs — because why hire a junior when there's a supply of Indian H-1B labor from shady consultancies, who won't complain or negotiate due to the constant threat of deportation?

What needs to be done is to end the exploitative aspect of H1B visas. Recipients should have a direct, unconditional pathway to residency, independent of their employer's goodwill. It shouldn't be a modern slavery.

Also, stop immigration fraud to prevent these visas from being used solely for cost-cutting and replacing local labor. Raise the minimum wage for H1B, introduce additional taxes — or just auction visas off, granting them to the highest bidder. So only the top talent would get them.

xpl··on Updates to H-1B
There is L1 visa that does not require a degree. And there is no quota/lottery. It requires you to work for a U.S. employer overseas for at least a year though.
xpl··on JavaScript Benchmarking Is a Mess
I once created this tool for benchmarking JS: https://github.com/xpl/what-code-is-faster

It does JIT warmup and ensures that your code doesn't get optimized out (by making it produce a side effect in result).

xpl··on Updates to H-1B
What is currently happening is the exact opposite.

There is a so-called "Technology Alert List" — a list of critical areas (nuclear, missiles, AI, etc.). If a person has a background in one of these areas, they get an automatic U.S. visa refusal during the interview.

Their visa application gets placed on indefinite hold (the so-called "administrative processing"), which can last for years even if it is eventually resolved.

Why? The U.S. government fears espionage. They worry that someone with expertise in a critical field might immigrate to the U.S., secure a job at a company with access to sensitive, export-controlled technology, and then leak that technology to Russia.

Even without espionage, such individuals could gain valuable experience in critical areas and later emigrate back to Russia — a reverse "brain drain."

xpl··on GitHub Copilot is now available for free
I didn't. Terms are subject to change + can be vaguely written. What matters is your data getting uploaded to someone else's cloud.

Even if they explicitly and clearly state that they don't use your data for any purpose other than generating immediate responses, they can change this once the free Copilot gains traction and people become really addicted to it.

Like, "pay if you don't want us to use your data for training". Most people won't pay and will be happy to give away their data instead.

xpl··on GitHub Copilot is now available for free
It is to collect more data for LLM training. To tap into proprietary code bases that are never uploaded to GitHub.

It is largely by design and serves to preserve cultural diversity. Without immigration caps, half of the U.S. would be Indians and Chinese.

xpl··on Romanian court annuls result of presidential election first round
> different from fraudulent votes

No, Putin would have won in elections even if you removed fraudulent votes (there is a fraction, but it is not at all decisive). He wins not because of it.

In those kind of countries elections are won way before the voting takes place. So the voting is just an act of the regime's legitimation and is irrelevant regarding the outcome.

xpl··on Romanian court annuls result of presidential election first round
> Voting is the only thing in the democratic process

Voting is not the only thing. If it was, Russia or Belarus could have been considered democracies — people get to vote there (in case you didn't know). You can research why those countries are commonly considered autocracies / dictatorships, despite holding elections.

> If the people are easily convinced by tictok, that's on the voters

If people are easily addicted to heroin, is that on them by that logic? Ok maybe. Now imagine if China were smuggling heroin into the U.S. specifically to destabilize American society — would you still blame the people? Or might you consider it reasonable to fight against that?

xpl··on Romanian court annuls result of presidential election first round
You're reducing elections to voting, while it is only the final stage of a proper democratic process.

First comes the preparation of the public opinion — it is campaigning, political advertisement, debates, etc. This shapes the voting outcome.

At this stage it can be heavily influenced by foreign actors (adversaries), this is why in most countries there are laws regarding the transparency of political campaigns (funding, ads, and so on). You can't let China elect presidents in your country...

> doesn't change the fact that people did in fact vote for him

It also doesn't change the fact that if Russia didn't pour a lot of money into his campaign, he wouldn't have gotten any votes.

xpl··on ‘With brain preservation, nobody has to die’
> Every time you go to sleep your consciousness shuts down. So, each morning is a copy of you wakes up

I think it doesn't "shut down", maybe fades away to a different, low-power mode. When you go to sleep and then wake up, here is still a continuity, because of the same underlying structures and processes from which the consciousness emerges. So it is like a 4D thing.

That continuity never really breaks (until death? which is like singularity) and I think this is what makes you "you". You can't copy/teleport it (kinda by definition), but you can extend/transform it.

Perhaps a "Ship of Theseus"-style approach would work — gradually replacing neurons one by one, or brain sections piece by piece. Alternatively, the brain could be extended with peripheral "devices" connected to it with bandwidth comparable to the interconnections within the brain itself, up to the point until the biological part becomes irrelevant. This is similar to how a portion of the living brain can be removed while still preserving consciousness — as neurosurgeons often demonstrate.

xpl··on The rise of the U.S., the rise of China
Yeah some people don't get that "property" is just as much a constructed concept as everything else is. It is an agreement/contract between people that is enforced by other people (e.g. the government).

Owning a home might seem more "real" than owning some IP, but it is just an agreement, and without a proper enforcement, anybody could enter and live in your house (which is what actually happens with squatters in some European countries where you're not allowed to kick them out by yourself and police don't care).

So property rights were never "real" (inherently) — they only become real when somebody kicks your ass for violating them. That's the only real thing about it.

xpl··on Sleep regularity is a stronger predictor of mortality risk than sleep duration
> Does anyone else consistently get 6 to 7 hours of sleep no matter what

6 hours is too little IMO. If I sleep 6 hours for more than a few days in a row, I feel like shit and need caffeine to wake up properly. Then I end up sleeping 10-12 hours on my days off to compensate (and to take a break from caffeine). It doesn't feel healthy.

So, I try to get at least 8 hours consistently. That way, I don't need caffeine at all and function just about fine.

xpl··on Skeptical of rewriting JavaScript tools in "faster" languages
This is often overlooked but is actually a big deal:

> ...it’s straightforward to modify JavaScript dependencies locally. I’ve often tweaked something in my local node_modules folder when I’m trying to track down a bug or work on a feature in a library I depend on. Whereas if it’s written in a native language, I’d need to check out the source code and compile it myself – a big barrier to entry.

I too often find myself inserting `console.log` inside node_modules to figure out why the toolchain doesn't work as I'm expecting it to. It has gotten me out of some very nasty situations when StackOverflow/Google/GPT didn't help at all.

Had it been written in Rust, I wouldn't have had a chance.

xpl··on How Israel’s bulky pager fooled Hezbollah
Yeah, but that is for "internal consumption" and it doesn't affect any international relations, unlike "declaring war".

An interesting example is the U.S. which has been in a "state of war" (official term is "period of hostility") since 2001, a.k.a. "War on Terrorism" — and it still is! Which, by the way, gives a nice bonus of immediate citizenship for signing up for the military, without the need to wait for 5 years.

xpl··on How Israel’s bulky pager fooled Hezbollah
Nations do not declare wars anymore, because wars are illegal since WW2. Quoting Wikipedia:

> Since 1945, developments in international law such as the United Nations Charter, which prohibits both the threat and the use of force in international conflicts, have made declarations of war largely obsolete in international relations

So since then, wars are now called "counter-terrorist operations", "peace enforcement operations", "special military operations" — you name it.

Nobody "declares war" anymore. See, for a defensive war (when a nation is being attacked) there is no legal need to declare it in the first place — and this is why Ukraine does not "declare war on Russia", and this is why Israel does not declare war against Hezbollah (and Hezbollah is not even a state to begin with) — it is a defensive war from the legal standpoint.

You declare an offensive war. And this is illegal. Once you do it, there will be legal repercussions, like troubles with purchasing weapons from other countries (as they often have laws prohibiting from selling weapons to countries at war). So why would anybody do it? It would be silly.

It's actually difficult to achieve even something as simple as getting a robot to stand upright. Most of them walk with bent knees and constantly shift from one foot to the other (e.g. Boston Dynamics).
xpl··on Tesla's Beer-Serving Optimus Robot Was Controlled by a Human the Whole Time
It's obvious. Imagine the PR disaster if the robot 'hallucinated' and said something inappropriate, or worse, accidentally pushed or hit someone. Why take the risk when everything needs to run smoothly?

The first time they showed Optimus, they literally had a human in the suit, so this is a huge step forward.

That said, a teleoperated humanoid body is an impressive tech feat by itself, seriously.
