nixgeek··on I'm Peter Roberts, immigration attorney who does work for YC and startups. AMA
I was thrown by you saying you were UK-based, if you have an L-1 then you’re able to reside and work in the US for that specific employer.

To change jobs on an L-1 you really need to have filed I-140 and be on the way toward your Green Card.

https://www.uscis.gov/policy-manual/volume-7-part-e-chapter-...

What this means concretely is if you have an L-1, an approved I-140 filed >6 months ago, and you’re now pending Adjustment of Status, I think it’s fairly safe to change jobs under AC21 (that’s what I did; this is not legal advice and I’m not an attorney, I took legal advice about my situation).

If you change jobs to work for Employer B after I-140 has been filed and >6 months has passed but *before* it is approved, I think that’s technically allowed in an authorization to work sense, however your L-1 is no longer valid, so if your I-140 filed by Employer A gets an RFE or Denial, you may be in difficult territory.

nixgeek··on We ensure Cloudflare customers aren't affected by LE's certificate chain change
They said “today, we’re not a Certificate Authority” — seems to strongly suggest they might be working to become one.
nixgeek··on Who is hiring interns (April 2024)
Microsoft has lots of intern opportunities at the moment.

https://jobs.careers.microsoft.com/global/en/search?q=Intern...

Location — Many (US, UK, Canada, Others)

In office? Many of these will want 2-3 days in an office. Others will not. Microsoft Careers (the link above) has the details for each.

You’d need to apply for a role at the company and then it would be situational and perhaps not immediate.

There’s no easy option that I’m aware about and just getting a US offer and having a US employer to help with immigration does not guarantee much —

You might be eligible for an O-1 if you possess graduate qualifications, publications or meet other options. “Person of Extraordinary Ability” essentially.

You might win the H-1B lottery.

You would not be eligible for an L-1 unless the US company has a subsidiary entity in your country, you work for that as a full-time employee for at least a year before applying, and then you (and your role) meet the bar for Multinational Manager/Exec or Specialized Knowledge Worker.

nixgeek··on AMD ROCm Going Open-Source: Will Include Software and Hardware Documentation
Looks like geohot is now advertising Team Green and Team Red options with the latter being $10k cheaper.

tinybox green - 6x NVIDIA RTX 4090 ($25k)

You came here to do ML and you want it to just work. You like checking out the latest open source ML stuff on GitHub. gpt-fast. You want your Attention to be CUDA quality FlashAttention. You want FP8. A solid box for the ML researcher. A solid box for the tinygrad developer. A solid box for everyone. It's just a little expensive.

tinybox red - 6x AMD 7900XTX ($15k)

You came here for the hardware.

You want to be a part of the journey. Make AMD great, with or without their help. Sure, it works for ML, mostly. Just maybe you have to reboot it sometimes. tinygrad does work well enough to get AMD on MLPerf at least. You buy the red box because you want to mess with kernel drivers and shader engines. You know what a warp is. You like that you can see the MMIO with umr. RDNA3 is documented! You want to get every bit of perf out of the metal.

The specs are similar to green, except it's $10k cheaper.

nixgeek··on Tesla releases Q1 2024 deliveries: disastrous results
I don’t think either had an EV option suiting my needs when we bought a Model X? Meaning able to seat 6-7 humans and ~300 miles of range in the battery pack?

Do they even have a viable option today? (I’m unaware how the Lexus electrification is going.)

nixgeek··on Tesla releases Q1 2024 deliveries: disastrous results
Some friends bought a Model X about six months ago, spending over $100k — that’s down from the almost $150k that Tesla was demanding a couple years ago when we bought one (and both were fairly fully loaded).

First, my experience 2 years ago was the A/C compressor was so loud that during summer with cooling running at maximum, you couldn’t hold a conversation in the cabin because of the noise. Tesla investigated and eventually said “looks fine to us, there isn’t designed to be any additional noise abatement on the firewall between the front and the passenger space”. We had issues with our Falcon Wing doors, and we eventually sold the vehicle after a year.

Now, our friends Model X, that’s had ~6 non-trivial maintenance problems in six months, including the Falcon Wing doors failing three times, and they’re in the process of trying to get a refund through Lemon Laws.

Other acquaintances who own Teslas also have service issues on their Model X, the Cybertruck looks like an even worse mess, so I concluded over a span of multiple years, quality still isn’t a strong suit of Tesla, thus I’m not shocked to see there’s limited brand loyaly, and with increasingly viable competition, demand is falling?

I now have a Rivian R1S and we are incredibly happy with that vehicle, having put about 6000 miles on it. Mercedes EQS also seems like a reasonable choice in 2024, depending on what you want.

nixgeek··on Police are tagging fleeing cars with GPS darts to avoid dangerous pursuits
In most (if not all?) parts of the US you are legally required to display a license plate and to not obscure it — those tinted covers you see people use are both a “Pull me over if you’re not otherwise busy!” to a lot of State Troopers (at least according to those that I occasionally shoot with on a pistol range), and ineffective outside nighttime (they reflect the IR emitter, but those often aren’t on in daylight).

So, how are you “interfering with third party data collection efforts”, while also meeting your legal requirements (government) obligations to display an unobscured and valid license plate on the vehicle, given the conversation is about ALPR/ANPR and where the tracking is a camera which reads the license plate?

nixgeek··on Reported Supply Chain Compromise Affecting XZ Utils Data Compression Library
I think there is an equally reasonable likelihood that nation state security and intelligence apparatus have disinformation capabilities that include monitoring and when necessary posting to and attempting to influence online forums like HN.
nixgeek··on Police are tagging fleeing cars with GPS darts to avoid dangerous pursuits
License plate readers (LPR) are common in cities and on motorways in UK; there are “Average Speed” zones where the LPR is accomplished by cameras mounted on overhead gantries spanning miles. Speeding tickets can be issued automatically if you break the speed limit between gantries. It’s always been weird to me the US doesn’t do this and often requires a trooper to pull you over and give you a written ticket. Note that not all motorways have this in UK, but those which do, you don’t see anywhere near as much excessive speed.

LPR is also used in UK by the Driver and Vehicle License Agency (DVLA) to oversee taxation of vehicles. No more “tabs” or license discs to display in your front window, it’s all LPR these days.

LPR databases are queryable by the security services and law enforcement — there are enough cameras in cities your location can be pinned down to “within a few streets”.

https://en.wikipedia.org/wiki/Automatic_number-plate_recogni...

This isn’t a tracker on every vehicle but it’s pretty equivalent for drivers who don’t live in the middle of nowhere where LPR may only be deployed in major towns.

nixgeek··on Sam Bankman-Fried sentenced to 25 years in prison
Insanely low? Insanely high?

SBF hasn’t really accepted responsibility or apologized through the trial, and didn’t at sentencing either.

Judge Kaplan seems to have taken a balanced view — far from the statutory maximum, less than the U.S. wanted, more than the defense wanted.

There will of course be appeals — SBF has already indicated he will file one.

There’s good coverage of what took place at sentencing today here — https://twitter.com/innercitypress/status/177334004374401064...

Also of note is since this is a federal conviction there is no parole in that system, and so unless SBF is successful in his appeal, he will spend at least 255 months in prison, that’s a 15% reduction versus the total sentence in return for good behavior while serving his sentence.

nixgeek··on AWS building 414 exaflops AI computer exclusively for Nvidia's internal research
Based on the 4x 66kW (albeit an A+B design) power shelves in these, this # of systems is basically an entire datacenter for AWS assuming they stuck to ~35MW buildings as they’ve done historically. It will likely be a little larger even than a normal building…

It’s only 288 racks of GPUs, based on 72/rack as NVIDIA disclosed elsewhere. Then whatever ancillary network is required. Pretty wild to use that much power over that few racks.

Seems like critical load when at 100% for the GPU racks is supposed to be 34.5MW and assuming 10% for 800GE networking to plumb it all together and a 1.2 PUE gets you to 45MW overall?

nixgeek··on Apple terminates Epic Games developer account, calling it a 'threat' to iOS
I doubt your supermarket chain has done things which rise to Phil Schiller responding to Epic with —

> We welcome all developers to the Developer Program so long as they follow the rules. Those rules, including the DPLA and the App Store Review Guidelines, are intended to protect the integrity of the ecosystem, developers large and small, and - most importantly-users. Accordingly, developers who are unable or unwilling to keep their promises can't continue to participate in the Developer Program.

> In the past, Epic has entered into agreements with Apple and then broken them. For example, you testified that Epic Games, Inc. entered into the Developer Program with full understanding of its terms, and then chose to intentionally breach the agreement with Apple. You also testified that Epic deliberately violated Apple's rules, to make a point and for financial gain. More recently, you have described our DMA compliance plan as "hot garbage," a "horror show," and a "devious new instance of Malicious Compliance." And you have complained about what you called "Junk Fees" and "Apple taxes."

> Your colorful criticism of our DMA compliance plan, coupled with Epic's past practice of intentionally violating contractual provisions with which it disagrees, strongly suggest that Epic Sweden does not intend to follow the rules. Another intentional breach could threaten the integrity of the iOS platform, as well as the security and privacy of users.

> You have stated that allowing enrollment of Epic Games Sweden in the Developer Program is "a good faith move by Apple." We invite you to provide us with written assurance that you are also acting in good faith, and that Epic Games Sweden will, despite your public actions and rhetoric, honor all of its commitments. In plain, unqualified terms, please tell us why we should trust Epic this time.

nixgeek··on GPS antenna mods make Starlink terminal immune to jammers
Would you explain why?
nixgeek··on ThinkPad T14 Gen 5 includes SODIMM slots and user-replaceable batteries
It's not like, say, Apple where the price is the price.

You can walk into an Apple Store, flash an employee badge from any number of companies, and get "Employee Purchase Program" price which is 4-8% off varying by SKU. Doesn't work for products at launch, seems to kick in around 12 weeks after. That's got me 8% off a Mac Studio and Pro Display XDR for personal needs. Whoever is assisting you in the Apple Store can lookup on their iPhone whether your employer gets EPP (and they're usually very happy to help!).

Buying in bulk from Apple as a business? You'll get at least 8% and potentially a fair amount more depending on your annual volume.

Apple discounts. Perhaps not as much as Lenovo. But the price is not the price.

nixgeek··on Profiteering hampers U.S. grid expansion
Not everyone should need a generator and a fuel store. Not everyone lives in housing which can even accommodate storing these safely, or operating them safely. These are exactly the issues I'd expect a well functioning government to actually solve, not "let natural selection work it out". What a horrible take, please can we not make light of 246 people prematurely dying across 77 counties in Texas, or imply somehow those 246 people were at fault?
nixgeek··on Airline Takes Revenge After Bad Review, Posts Passenger's Passport Online
One should be able to post a negative review of any corporation’s product or service.

I think it is important to recognize that's a predominantly Western take, and that free speech with consequences for reactions like this isn't close to a universal right today in the world.

In a lot of places, posting criticism and negative takes of things can have pretty serious ramifications, ranging from being doxxed (in this case) by a business, to at the very extreme end, your critical speech can lead to a trial, conviction, a penal colony and your death (Navalny in Russia).

What I meant with "Fsck around; find out" is the threshold for that absolutely varies by the geography. In the US (to pick an example country), as you say, this would be outrageous behavior by the airline with potentially serious consequences in either a civil or even criminal liability sense. Overseas? Potentially not so much, and I think your risk calculus as an influencer on these things (i.e. thinking about flying a small/local airline like this) needs to factor in the local atmosphere?

nixgeek··on Airline Takes Revenge After Bad Review, Posts Passenger's Passport Online
It feels like the 'influencer economy' has money plus goods/services changing hands in return for reviews all over the place, and the bar for disclosing things like affiliate links exists, but adherence to that bar is mixed with influencers, and enforcement of that bar also seems rare (at least in the US).

Is it possible to believe that a travel influencer with 700,000 subscribers (plus whatever other channel statistics matter to doing these deals with Marketing departments; number of views, watch times, number of click throughs?) would expect a free flight, some accommodation, a food allowance, and some money in return for the time and effort to do the flight, edit a video, post it? Likely yes.

Does that make it okay to post his personal details? No.

But this does seem like the definition of "Fsck around; find out", given the influencer in question has posted lots of stuff *slamming* other businesses, and they've now done it in a country where the airline's response isn't illegal, and the airline isn't covered by IATA's code of conduct, so they have no recourse.

nixgeek··on Apple Watch Ultra 2 Hacked
In the discussion thread, it's stated:

I stared pressing the button to return home and they popped up the keyboard and typed “We are in control”.

That would be a very unusual ghost touch issue, if true.

nixgeek··on Fly.io has GPUs now
That hasn’t been my experience with Fly but I’m sorry to hear it seems to be others :(
nixgeek··on Cloud Egress Costs
Notably, anywhere in the AZ is simply a launch constraint, and the hyperscaler can and does place you in the most advantageous way for them which matches against the 'customer promise' (constraint). They in practice do model both the volume and cost of East-West traffic in their network topology and will wherever possible not place Instance A and Instance B all that far apart in the AZ, particularly if that AZ is one of the big ones with 20+ datacenters worth of capacity.

All the other points you made are also excellent.

nixgeek··on Security flaws in an SSO plugin for Caddy (2023)
No, but I'd also hope that new and existing users of what's probably a popular middleware for Caddy aren't expected to read 100's of open GitHub Issues or luck upon the Trail of Bits report to know there are significant unresolved security issues and the maintainers don't have the time or resources to actually fix them.

Better know that up front, than get popped and think "What happened?".

nixgeek··on Home Assistant: Three years later
Do you write about your picogrid and other MEP stuff anywhere?
nixgeek··on Cloud Egress Costs
A good chunk of network capital is also amortized into these costs, it isn't just the 20 cents per megabit for IP settlement, it would also be all the routers those ports are connected to, the racks those sit in, the electricity those consume, and the networks beneath that from the hypervisor upwards.

Add on the usual and egregious $150-400/mo for a SMF/OS1 crossconnect in many datacenters.

Now, I'll grant you, "not even close" and handsome margins likely still applies but "I'm going to hook a server directly into a 1Gbps IP transit port for $200" vs. all the complexity of a hyperscaler network is not apples to apples.

nixgeek··on Nine US states are teaming up to accelerate the adoption of heat pumps
You can do that. It’s very common in New England to go this way because the heat pumps generally only work down to -15F and then you need to switch to furnace for heat.
nixgeek··on Weaveworks is shutting down
According to LinkedIn they were 50-200 employees which after excluding all the other costs for running a company, is definitely not enough to cover the fully-burdened payroll of even a 50 person organization that’s probably predominantly Engineering types, that assumption being if most people are US-based (or if they don’t do “location based” pay, and indexed off a more expensive location).
nixgeek··on More misdrilled holes on 737 MAX in latest setback

nixgeek··on Tesla Employees Using Vehicle Cameras to Spy on 'Private Scenes;' Owners Suing (2023)
“For example, when a Tesla hit a child riding a bike, a video of the child flying through the air went viral among employees. They shared it in private one-on-one chats “like wildfire,” according to another ex-employee.”

This is disgusting and if it’s true and especially if Tesla management was aware of these issues and failed to take action, we can but hope a judge and jury will see fit to award the class an enormous sum.
