sgjohnson··on Three years in North Korea as a foreigner (2021)
> Which would completely invalidate the entire purpose of the SCIF, no?

Yes. But if you belong in there, nobody is going to second guess you.

sgjohnson··on Southwest flight came within 400 feet of crashing into the ocean
> it's something like 300

It’s actually 0 in Europe.

sgjohnson··on macOS 15.0 supports Nested Virtualization on M3 chips
Windows Server is actually quite tightly controlled licensing wise.

Any client user/device using any service on the server requires a client access licence (CAL).

sgjohnson··on I connected Windows XP to the Internet; it was fine
So it was behind a firewall. Now do it without a firewall.
sgjohnson··on Reclaiming IPv4 Class E's 240.0.0.0/4
Yes. A /48 of v6 is perfectly announcable.

There is no functional difference between PA and PI.

sgjohnson··on Reclaiming IPv4 Class E's 240.0.0.0/4
Exactly. I have a PA /32 of IPv6 that I can sub-allocate and announce however I want. Or even lease to other people. It's my space, as long as I'm paying my LIR for it.
sgjohnson··on Reclaiming IPv4 Class E's 240.0.0.0/4
You can do whatever you want with that PA assignment. PA means that it's the provider's address space, not yours. You can announce it wherever you want though.

The Wikipedia explanation is flat-out wrong.

sgjohnson··on Reclaiming IPv4 Class E's 240.0.0.0/4
It’s not actually expensive or difficult for an individual to get an ASN and IPv6 space.

https://lagrange.cloud/products/lir £15 one-off for an ASN and £7/y for a /48.

Then you just need to find someone to give you a BGP session. https://bgp.services

sgjohnson··on Cloudflare took down our website
The costs for announcing the customer's IPs and making sure that only they are the ones actually sitting on them would be minuscule. Nowhere near $10k/mo. Maybe $100/mo.

Anycast/unicast changes nothing here. Anycast simply means that the same prefix is announced in multiple different PoPs.

sgjohnson··on All-cash offers, wealthy buyers push Southern California home prices to a record
Except housing costs don’t stop beyond the $5500 on the mortgage. Add all the utilities, property taxes, insurance, and the monthly average of maintenance fees and it’ll probably be closer to $8-9k/mo.
sgjohnson··on All-cash offers, wealthy buyers push Southern California home prices to a record
> $5500/mo for a 3 bedroom property with additional appreciation is a great deal in any market.

What are you smoking? This is insane even on two $150k salaries. It’s 60k a year on the mortgage alone, when your households total take home pay is under $200k.

sgjohnson··on I'm Peter Roberts, immigration attorney who does work for YC and startups. AMA
I believe he's asking if he qualifies under the "one-time achievement" here

> You must meet at least 3 of the 10 criteria* below, or provide evidence of a one-time achievement (i.e., Pulitzer, Oscar, Olympic Medal) as well as evidence showing that you will be continuing to work in the area of your expertise. No offer of employment or labor certification is required.

I'd like to think that continuing to play chess professionally under the US flag would qualify as "continuing to work in the area of expertise", as this is a self-sponsored visa anyway.

Here's a case study from 2011 that says "yes, it qualifies". https://www.wegreened.com/blog/eb1/case-study-aao-sustained-...

> Oh wow. Your wife is going to have to prove she hasn't abandoned her residency, which is normally automatic with a 2+ year absence (or even 1+ year without a re-entry permit).

Practically, it depends on how picky the CBP officer is. I personally know of a guy who re-entered the US on his Green Card after a 7 year absence. From what he told me, he didn't even get sent to secondary inspection and was just welcomed back home. He flew into JFK.

I don't see them yoinking the GC of someone who has a US citizen spouse because of >2y absence, even though the law tells them to.

> In the US the Bill of Rights and most other things only apply to citizens (and maybe lawful residents).

No, the US constitution applies to absolutely everyone in the US. Even illegals.

sgjohnson··on 'Lavender': The AI machine directing Israel's bombing in Gaza
Ah yes, the UNRWA, the notoriously unbiased UN agency when it comes to palestinians.

> More children in Palestine have been murdered in 6 months than in every other conflict in the world combined over the last four years.

If you really believe that, I’ve got a bridge to sell you. https://en.m.wikipedia.org/wiki/List_of_ongoing_armed_confli...

sgjohnson··on Tips for linking shell companies to their secret owners
> is now left as the single biggest western tax haven in the world.

Only for non-residents though. So you can't have a green card, or US citizenship, and you have to stay well clear of the Substantial Presence Test (https://www.irs.gov/individuals/international-taxpayers/subs...).

sgjohnson··on 'Lavender': The AI machine directing Israel's bombing in Gaza
> I'm on whichever side that doesn't deem it acceptable to deliberately kill kids by the thousand.

Unfortunately, that side doesn’t exist in this world. Civilians have died in every war ever known to man. Whether they are kids or not is completely irrelevant.

sgjohnson··on 'Lavender': The AI machine directing Israel's bombing in Gaza
I'm convinced that there's no way to fight a war without pissing someone off.

Even more so, it's impossible to fight an _assymetric_ war without pissing a lot of people off.

> Targeting hospitals without clear proof of military activity is against international law.

What's "clear proof" is in the eye of the beholder.

> As is collective punishment, using starvation as a weapon of war

I'm actually willing to give Israel the benefit of doubt here, as they actually have no experience whatsoever in coordinating large scale aid deliveries, even if delays somewhat further their goal of punishing palestinians.

> UK government lawyers say Israel is breaking international law, claims top Tory in leaked recording

So what? Every major player on the world stage breaks international law whenever they damn well please, UK, US, Israel, China, Russia, they all do, to the point where in my eyes "x is breaking international law" is a completely worthless statement. Nobody is really going to do anything about it if you're on the right side of the new iron curtain.

This might be very cynical from me, but honestly, can you name the last time when the words “international law” carried any real weight?

sgjohnson··on 'Lavender': The AI machine directing Israel's bombing in Gaza
If Israel didn't care about international law, all of Gaza would now be a smoking crater and the death toll would be an order of magnitude higher.

> That is, only members of the armed wing of Hamas (not recruiters, weapon manufacturers, propagandists, financiers, …) can be targeted for attack - all the others must be arrested and/or tried.

In theory, yes. In practice--in which make believe world is this true?

sgjohnson··on Recent 'MFA Bombing' Attacks Targeting Apple Users
> Do Apple definitely not retain a key?

If this is the threat vector you’re worried about, you shouldn’t have had anything in iCloud (or any cloud for that matter) to begin with, rendering this debate completely moot.

sgjohnson··on Writing Gnome Apps with Swift
Swift is open source.
sgjohnson··on Recent 'MFA Bombing' Attacks Targeting Apple Users
Turn on Advanced Data Protection before you rip up the key. Then it's all as good as deleted.
sgjohnson··on Reverse DNS IPv4 Map
Are you aware of what SLAAC does? For the most part your scan results are going to be useless in <24h
sgjohnson··on Reverse DNS IPv4 Map
Yeah, just go ahead, scan PTR records for some mere 2^120 addresses.

Even if we scan just the first address of each /64, it’s still about 2^56. Unlikely anyone is ever going to do it.

This is another thing I like about IPv6. Makes mass address scanning completely useless.

sgjohnson··on Reverse DNS IPv4 Map
That’s actually exactly the reason why Cloudflare got it. They were the only ones at that point who could handle all the garbage that was sent to it, and willing to deal with it at their own expense.
sgjohnson··on Ask HN: How should organize and back up 23 TiB of personal files?
Tape drives are a viable option. 6TB LTO-7M8 cartidge can be has for $50.

The drive is expensive, at $4k, but it’s still the perfect solution for long-term archival, because the cartridges weigh and cost damn near nothing.

Yes, there’s large upfront cost, but after that the cost per MB will slowly approach the rock bottom price of how much the cartridge costs.

sgjohnson··on Free data transfer out to internet when moving out of AWS
Nor it is intended for you to.

It’s meant for situations where you intend to leave AWS for good, not spin up another EC2 instance when you need it, generate terabytes of data and then transfer it out for free.

sgjohnson··on Free data transfer out to internet when moving out of AWS
on-prem is still “the internet”
