sgjohnson··on USCIS announces strengthened integrity measures for H-1B program
One thing I find really, really weird about the US immigration system is that immigrating illegally is trivial (apparently even more so nowadays than it was 15 years ago), and it even comes with a loophole that can make you a legal immigrant later, yet legal immigration is a very tedious and often impossible path.

I have a relative that 15-ish years ago simply overstayed their tourist visa and never left. Some 5 years later he found a chick and put a ring on it (and because he married a US citizen, all his overstay was instantly forgiven). Then he had a immediate US citizen relative who sponsored him for a green card, which he got a couple of years ago. In a couple of years he can apply for naturalization. Yes, he couldn't leave the US until he had the GC in his hands, but I'd say it was a small price to pay for a massive shortcut.

For a married European that would love to live in the US, like myself, legal immigration paths are simply not viable. I would not accept a non-immigrant visa (like H1B), because it doesn't come with any guarantees that I'll be able to stay in the US, and legal immigration paths are basically limited to winning the DV lottery or coughing up $900k for the EB5, as no company in the right mind would sponsor me for an EB2/3.

And for many people from oversubscribed countries (like India and China), marrying a US citizen is the ONLY viable path to a green card.

US immigration system is fundamentally broken.

sgjohnson··on Why you've never been in a plane crash
Amazing, I didn't know of this incident. Awesome airmanship.

> One of the harrowing details is this quote: "The crew contacted United Airlines maintenance personnel via radio, but were told that the possibility of a total loss of hydraulics in a DC-10 was considered so remote that no procedure was established for such an event."

Has this even changed? What can you even do in the extremely unlikely scenario of loss of all hydraulic systems? I don't think it's even possible to train for such a scenario. You are truly on your own. What would the checklist even look like? "try doing the best you can with engine thrust alone, and may god help your soul"?

As far as I'm aware, the engineering has gotten better (introduction of hydraulic fuses that keep a closed loop in case there's indications of leakage), but truly, what can you even be expected to do without flight controls.

sgjohnson··on Why you've never been in a plane crash
I didn’t suggest that Airbus has similar issues. What I meant by the “entire industry” also includes the airlines.

I suggested that had nothing changed, it might have been Airbus that was low-key blackmailed into making a new plane that’s of the same type, with similar issues that would become evident only after a couple of crashes.

The very root cause of the issue was that Boeing was simply allowed to say “trust me bro, this is just a 737, it’s like any other 737, no retraining of any kind needed”, when, in fact, it wasn’t just the same old 737. Now this can’t happen anymore.

sgjohnson··on Why you've never been in a plane crash
Total loss of control basically never happens. I’ve been reading and watching a lot of videos on aircraft accidents and near misses, and I haven’t seen a single one where there truly was a total loss of all controls over the aircraft.

Even in the case of Japan Airlines Flight 123 (https://en.m.wikipedia.org/wiki/Japan_Air_Lines_Flight_123) the pilots still had some degree of control over the plane after its tail was ripped off due to a structural failure leading to explosive decompression at cruising altitude which also caused a total loss of all hydraulic systems.

Unfortunately what they had left (control over the engine thrust) was not enough, but they sure did their best. Apparently you can still control (to some extent) the plane using just the engines, with and the vertical stabilizer being completely gone, and no hydraulics. And this was in 1985.

I’m not saying that JAL 123 was in any way survivable (although some miraciously did survive), just pointing to the fact that even in the worst possible scenario there’s still probably a way to somehow control the plane.

> Otherwise events like the MCAS disaster would be just an "happy accident" with no one to blame.

But it was. Boeing being allowed to self-certify their own aircraft was ultimately what allowed it to happen.

sgjohnson··on Why you've never been in a plane crash
Boeing fucking up with the 737 Max so much is merely a symptom.

They so desperately needed it to remain a 737 so it wouldn’t be a new type and therefore wouldn’t need a new type rating was mostly because the airlines demanded a better 737.

Yes, Boeing is at fault for the MCAS disaster (no redundancies, holy fucking hell), but in reality it was the entire industry.

My point is, had nothing changed, it would have happened anyway, and perhaps with Airbus and not Boeing.

The one big oopsie is “we want a better plane and we also don’t want to retrain our pilots”, which is an oopsie that absolutely was not Boeing’s fault.

Furthermore, their misbehaviour couldn’t even be tried in a normal courtroom, even if there was mass public and political support for such an action.

They’d have to be tried in a secret FISA Court.

sgjohnson··on I realized chess pieces can be redesigned to be geometric attack directions
> this almost means a queen, but a promotion to knight can also be useful

So can a promotion to rook or a bishop, if for example promotion would cause a stalemate, especially if you're in a zugzwang.

Although such situations in actual real-world chess are _exceedingly_ rare, they make for a good puzzle material.

sgjohnson··on Proposed UN cybercrime treaty has evolved into an expansive surveillance tool
> modern decentralized networking

But the internet is already completely decentralized and has been since the 1990s when we switched from EGP to BGP. EGP used to have a single, global "backbone", BGP doesn't.

The only semi-centralized part of the internet are the regional registries, although IANA is still the supreme numbers authority, but they don't care about what you do with your assigned numbers unless you hijack other numbers or acquired yours fraudulently.

just look at the ND table. Nobody is ever going to scan a single /64 of v6, ever.

that would be because nukes are completely useless against anything assymetrical

Yes, but you still need local handlers for them, and they would be “foreigners trying to blend in”

That we definitely can agree on. Although I’m not in denial. I’m not willing to compromise on my lifestyle one bit for environment.
sgjohnson··on DARPA Moves Forward on X-65: Plane with no moving control surfaces
Presumably, this would be operated in hostile territory, so nobody would particularly care about it turning into a giant fireball upon crash landing. Or self-destructed when still airborne.
sgjohnson··on Macs can now inform Apple if any liquids have been detected in the USB-C ports
> I don't understand why people put cases anymore.

Personally, because I hate the camera bumps. So I have a case that’s thick enough that allows my phone to lay dead flat on the table. Which is the only reason for me to use a case.

sgjohnson··on Email addresses are not good 'permanent' identifiers for accounts
> You can still look exactly like someone else

But you can’t have a username that looks exactly the same anymore.

I’m in some 140 discord servers. The amount of spam from people impersonating someone popular has reduced drastically since this change.

I wouldn’t call “one click” an investigation.

sgjohnson··on Email addresses are not good 'permanent' identifiers for accounts
> but I'm still curious why they switched.

Because it was trivial to impersonate someone. The old usernames supported full UTF-8, enabling a wide variety of attacks.

And by paying for nitro, you could choose the numbers too, so step 1. Find someone you want to impersonate, copy their username, and replace one character with a visually identical one, but a different one. Step 2 - pay for nitro, and choose the numbers too.

As usual, malicious actors are the reason why we can’t have nice things.

sgjohnson··on The high price of empty office space
> In announcing M-CORE in May, Adams portrayed the new tax break as a step to protect the city’s budget and the services it funds. “Every office sitting empty means less funding for everything from schools and affordable housing to emergency food and police officers, and that’s why it’s vital we get workers back into offices,” he said.

Comedy gold. Nobody needs more overpriced office space in NYC. If people needed more overpriced office space, it most likely wouldn’t be sitting empty. Plenty of people need more housing.

VirtualBox is hot garbage. There are other virtualization tools that work perfectly fine on Apple Silicon. Like UTM. Or Parallels.
sgjohnson··on Electricity That's Too Cheap to Meter
> wind power genuinely became too cheap to meter.

No, it didn’t. The grid must always be in balance. Wind power production can’t be ramped up or down as needed. Overproduction could cause a surge on the grid, that would in fact be a massive liability for the power company.

Power became free for those periods because it was the cheapest option for the producer.

Kind of how it happened when crude oil was trading at negative $57 per bbl. The contracts came with an obligation that was impossible to meet, thus it was easier to pay someone to take them off your hands.

sgjohnson··on Meta censors pro-Palestinian views on a global scale, report claims
> 15 seconds of internet for the first things that entered my mind. It's really not that hard.

You know full and well what I’m talking about. Virtually nobody that’s far away from those conflicts posts pro-whatever side content on their social media. Mainstream media basically doesn’t talk about any of those.

My claim was that “nobody cares”, not that “there are no articles whatsoever being written about children dying in other conflicts”.

sgjohnson··on Google is apparently struggling to contain an ongoing spam attack
> No? Decreased search quality will reduce the number of searches people are doing which redcues the amount of ads Google can show.

I’m willing to bet that >90% of Google Search users aren’t even aware that alternatives exist.

They are not suddenly going to stop using Google Search. There might even be a significant short-term increase in usage, for example, if they really need to go to page 5 to find the first relevant result.

sgjohnson··on Google is apparently struggling to contain an ongoing spam attack
To be honest, why would they care?

If anything, this will help them sell more ad spots on Google Search.

sgjohnson··on Google is apparently struggling to contain an ongoing spam attack
> Google is a marketplace

No. Google is a glorified advertising agency who just wants to make the absolute maximum profit for the absolute minimum amount of work.

> By now most paid results offer more value for the users than the organic results. Cause thats what Google wants. Click the paid, ignore the crap.

Your first paragraph implies that the paid results are crap too?

sgjohnson··on Acer Aspire 1 ARM Laptop Has Nearly Complete Upstream Linux Support
> Except for dropping 32bit libraries and all that?

That has got nothing to do with ARM. Apple decided to drop support for 32 bit apps several years before they introduced M1.

You still can emulate it.

Have you considered replacing the machine with a new and improved one every year or two?

Sorry, couldn’t resist.
