lorenzhs··on Crypto is 'rat poison', a third of mainstream investment firms tell JPM
Almost, it was Warren Buffet (the article says this). More: https://www.cnbc.com/2018/05/05/warren-buffett-says-bitcoin-...

Edit: apparently Buffet was referring to an earlier statement by Munger

lorenzhs··on Evaluating necessity of Covid-19 vaccination in previously infected individuals
What they might have meant is that many countries accept a positive PCR from >= 4 weeks ago as proof of prior infection (and therefore, presumed immunity), but not an antibody test. I'm not familiar with the error rates of the latter, but for the purposes of travel a positive antibody test is rather useless.

Where I live, you need to meet one of three conditions for things like indoor dining:

- proof of a full course of vaccination (2 weeks after the final shot)

- proof of prior infection - antibody test not accepted, only positive PCR between 1 and 6 months ago

- proof of an antigen test (rapid test) that's at most 24h old

lorenzhs··on Evaluating necessity of Covid-19 vaccination in previously infected individuals
Antigen tests (the rapid test kit, results in ~15 minutes, sample taken from the nose or thread) are not the same as antibody tests (blood test for prior infection, has to go to the lab). You need the former for travel. Afaik, the latter is not accepted as proof of prior infection, you need a positive PCR test from at least 28-ish days ago.
lorenzhs··on Apple pays out millions to student after repair techs shared her personal images
If that's your threat model, you should not be using any repair shop. And the attacks you describe are not just "a bit more sophisticated than Ctrl+C/Ctrl+V", they're most likely far beyond the abilities of most repair technicians.
lorenzhs··on Ubuntu 21.04
Are you aware that you've been running a version that hasn't been getting updates since July of last year? If not, then having your OS actually get updates again might be a surprise. You'll have to update to 20.04 first, though, and then 20.10 before you can update that to 21.04. There's no direct update path (another known surprise, one might say). If you don't want to update every six months, just stick to the long-term support version (LTS, currently 20.04).
lorenzhs··on No More Nanometers – It’s Time for New Node Naming (2020)
You're moving the goalposts. After being delayed numerous times and the first parts being of rather questionable usefulness, Intel's 10nm process is doing fine now and shipping in volume. Noone claimed that they had closed the gap to AMD with the 10nm Xeons, only that they're shipping. (They also significantly narrowed the gap, but it remains quite large).
lorenzhs··on Apple Now Selling More M1 Macs Than Intel-Based Models, Says Tim Cook
Does Intel sell their laptop processors directly to consumers?
lorenzhs··on No More Nanometers – It’s Time for New Node Naming (2020)
It's not "barely usable" any more, they're shipping Xeons with up to 40 cores at volume. Afaik everything except high-clock desktop parts is shipping on 10nm now. It took them an eternity, but it's not Duke Nukem late.
lorenzhs··on The war against money-laundering is being lost
Yes, but the link I posted goes into significant detail why numbers as high as those in your link can't possibly be accurate.
lorenzhs··on Surface Laptop 4
I have two 24" 1920x1200 (16:10) monitors at work, one of them rotated 90 degrees. I previously had to 24" 1920x1080 (16:9) monitors in the same configuration, and 16:10 is far preferable imo. The 1080 pixel width is often just a little too narrow for comfortable browsing (causing mobile layouts to be used or horizontal scrolling to be necessary), and I haven't had any of that since switching to the 16:10 monitors.

My home (and home office) setup is 14" 1920x1080 laptop + 24" 2560x1440 screen (1x scaling), and I like that a lot, too. The WQHD screen is wide enough to have two things open side by side, which can feel cramped on FHD, while also having sufficiently many vertical pixels.

lorenzhs··on WhatsApp's new privacy policy is so bad it might be illegal
When is the last time you used it? Because I have none of these issues. None. Especially since "It doesn't sync with your mobile client unless you open the app on your phone" is architecturally completely wrong. The desktop client doesn't communicate through your phone. That's how WhatsApp web works, but Signal Desktop doesn't.

lorenzhs··on The war against money-laundering is being lost
Less than bitcoin, while providing actual value? According to Netflix's 2020 ESG report [1], their hardware infrastructure used just under 95 GWh in 2020 (not including data transmission or your TV). All of which was from renewable sources, btw. Including transmission and the end-user's viewing devices, watching Netflix is estimated to use 77W of power [2], for a total estimate of around 1.2 TWh per year. Bitcoin is estimated at 140 TWh per year [3], or 1500 times Netflix's data centre power usage, or a 120 times the likely total energy consumption of watching Netflix.

Going further, all data centres in the world use an estimated 200 TWh per year, and data transmission networks are estimated at 250 TWh per year [4], for a total of 3.2 times Bitcoin's energy use. Maybe it's just me, but the value provided by the internet is more than 3.2 times higher than that of Bitcoin.

lorenzhs··on Ask HN: Why is the Linux community struggling to implement hibernation?
No, this isn't beyond evil maid - it doesn't require physical access, it only requires root access.

Increasingly, root and kernel access aren't the same thing any more (if you enable lockdown mode). That stops root from doing a whole bunch of things. It's true that often, user-level access is enough (if you only care about the user's data). But if you want to modify syscalls or do some other thing that root may not do in lockdown mode, you'll need to get kernel access. And many other ways of getting there have been blocked in an attempt to strengthen the barrier between root and kernel (some dispute the utility of that separation, but I think it's because they fundamentally reject its goals). This is about closing another hole in the barrier.

How useful that barrier is against attacks of the https://xkcd.com/538/ kind is, of course, a different matter. In my view, the point is that it raises the cost.

lorenzhs··on Ask HN: Why is the Linux community struggling to implement hibernation?
Because you mentioned secure boot and encryption: Matthew Garrett wrote an interesting blog post a while ago on making hibernation work with lockdown mode, i.e. verifying that the hibernation image wasn't tampered with. Otherwise it might be possible to get around the whole secure boot chain by writing a compromised kernel to a hibernation image. It's quite interesting to think about, even if it isn't necessarily something you as a user should need to think about (distros should probably handle it): https://mjg59.dreamwidth.org/55845.html
lorenzhs··on Booking.com fined €475k for reporting data breach too late
On GDPR, it seems HN has two completely opposing reactions depending on the time since a fine has made headlines. If it's been a while, the prevailing sentiment seems to be "the big bad EU will financially ruin me for my side project if I don't hire a full-time data protection lawyer", and when a fine is actually issued, it's "that's not even a slap on the wrist, who's going to care, lol". It's almost as if EU data protection agencies reacted proportionately to the severity of the misdeed. This is a leak affecting 4109 customers, after all, not a full compromise of booking's systems.
lorenzhs··on Booking.com fined €475k for reporting data breach too late
Your numbers are off by 3 orders of magnitude, the fine is just under half a million, not half a billion.
lorenzhs··on Icecream: Never use print() to debug again in Python
I mean it's not particularly pretty but what's so bad about this?

    std::cout << std::hex << my_int << std::dec << std::endl;
lorenzhs··on The Drivers Cooperative
If you're a large retailer and have been able to negotiate good rates with a payment processor and are in a country where interchange fees are capped (e.g., EU countries), then I can see it. But I doubt that it's the case in the US where those fees have to fund 2% cashback programmes etc.
lorenzhs··on Super Resolution
There are non-Adobe alternatives with ML super-resolution features that are much cheaper. For example, Pixelmator Photo can do it for $8 (iPad, no subscription). They have a Mac version as well but I don't use macOS so I can't judge that.
lorenzhs··on Why in the world would you own bonds?
When investing the same amount every month (dollar-cost averaging), the difference becomes even larger. Using your portfolios, but adding $250/month in addition to the initial investment of $10k, you end up with $128k with gold and $207k with SPY (total investment ~$85k): https://www.portfoliovisualizer.com/backtest-portfolio?s=y&t... (with QQQ, it'd be $380k)

Comparing one-off investments is very dependent on the start date, and dollar-cost averaging more accurately models what people can actually do and which returns one may be able to expect. Who has a large lump sum laying around to invest rather than investing a portion of one's income every month/quarter?

lorenzhs··on Why inflation is not a threat
Shelter accounts for 33% of the index, not 24%: https://www.bls.gov/news.release/archives/cpi_02102021.htm - I'm not sure where your figure originates, but it's wrong.
lorenzhs··on Why inflation is not a threat
That's a common misconception of how money creation works. If you want to learn more, this Bank of England article is a good introduction (pdf): https://www.bankofengland.co.uk/-/media/boe/files/quarterly-...
lorenzhs··on Based Cooking
In the UK, iodine is added to cattle feed instead of salt, so it's contained in dairy products. No idea whether this can be a problem for vegans.

"Kosher salt" isn't a thing this side of the pond (at least in Germany). Even regular coarse salt is not something you can expect to find in an average kitchen.

lorenzhs··on Based Cooking
In lots of countries, butter isn't sold in sticks, and using measurements like "sticks", "cans", or "packs" of something is annoying if the unit sizes differ between the author's and the reader's country. I can deal with cups or ounces - they're not intuitive for me, but they can be converted. But "cans" or "packs" are just plain guesswork. That makes it unnecessarily hard to try new dishes where I don't already know what the result is supposed to look or taste like.

If your surname contains an "a", say Gaddersby, you could also do "g@dders.by" to confuse people even more
lorenzhs··on Nuclear power looks to regain its footing 10 years after Fukushima
Hinkley Point C has been delayed until at least June 2026: https://www.bloomberg.com/news/articles/2021-01-27/edf-sees-....

Another reactor of the same EPR model family that EDF is building in Flamanville, France, started construction in 2007 with commercial introduction originally scheduled for 2012 but now delayed to 2023 (no official statement with that date, but fuel loading is estimated only for the end of 2022 and it takes a few months after that). It's also five times over budget (€19.1bn, original estimate was €3.3bn, for one reactor with 1.6GW of electrical output).

Yet another one, Olkiluoto in Finland, began construction in 2005 and is also not finished, with commercial introduction planned for 2022. Its cost is estimated at €11bn, but was supposed to be €3bn originally.

The two operational ones, Taishan 1 and 2 in China, took 10 years of construction, too. It was planned to take less than 2 years.

lorenzhs··on Fire declared in OVH SBG2 datacentre building
There are photos of the fire suppression system in one of their data centres in this (French) forum thread: https://lafibre.info/ovh-datacenter/ovh-et-la-protection-inc.... They have sprinklers, with the reasoning being that the burning racks' data is gone anyway if there's a fire, and at least sprinklers don't accidentally kill the technicians.
lorenzhs··on Fire declared in OVH SBG2 datacentre building
In French but with pictures: https://lafibre.info/ovh-datacenter/ovh-et-la-protection-inc... - probably a different OVH data centre, but they clearly have sprinklers there. The argument they made against gas extinguishers is by the time they have to use it, the data is gone anyway, and it's only going to trigger in the affected areas. It's also far safer for the people working there.
