delroth··on We need a replacement for TCP in the datacenter [pdf]
> Google hasn't used TCP in the datacenter for years.

That's absolutely false. I don't have any sources except for having worked at Google from 2013-2022, but it's not like you quoted any sources either, so...

There's a reason why Google is still releasing stuff like TCP BBR (2017).

delroth··on Linux M1 GPU driver passes 99% of the dEQP-GLES2 compliance tests
See https://github.com/AsahiLinux/docs/wiki/Feature-Support . The laptops are very usable as a daily driver on Linux already, but not 100% is supported and depending on your specific requirements some of the missing hardware support might be a deal breaker. You can very much run a normal Linux desktop with a working UI, that's been working for months, it just doesn't have hardware rendering acceleration (but the CPU is fast enough to make this tolerable).
delroth··on Vogtle Unit 3 starts nuclear fuel load
Again, the claim on the website is "has the potential to power over 91,000 homes". "up to", "has the potential", etc. But let's do some quick back of the envelope maths.

91,000 homes would be about 91,000 * 3,000 kWh / year = 273 TWh / year. You need an average of 31 MW over a year to produce this, which roughly tracks 350 MW with ~10% capacity factor. So over a year this seems to be correct.

On a day to day basis however the project only includes 700 MWh of storage. That's about 24h of the electricity consumption of 91,000 homes. A single cloudy winter day and those batteries are empty. So if you look at shorter time periods than a full year there's a huge variation in how many households can actually be reliably powered by such an installation. It's likely somewhere between 1,000 (several days of cloudy winter) and 350,000 homes (sunny summer).

delroth··on Vogtle Unit 3 starts nuclear fuel load
You skipped the critical "up to" part when re-quoting this in your previous message. The capacity factor is what determines how close the average is to that theoretical maximum. With 10.8%, the answer is "not close at all".

delroth··on Native Linux GPU Driver for Apple M1
Box64, FEX-Emu and other x86-64 on ARMv8 emulation projects cover that gap and explicitly target gaming as a core use case. And of course there's Apple's Rosetta, which we know is good enough for gaming on ARM macOS. Apple has released a Linux version which should technically be able to run on Asahi, but I'm unsure of the legal situation around this.
delroth··on Europe's Newest Nuclear Reactor Eases Finland's Power Problems
Because the European grid usually has less demand, more supply in summer and more demand, less supply in winter. This leads to EDF scheduling most maintenance and refueling for nuclear power plants in summer. This year was particularly bad because the normal summer maintenances were accompanied by 1. a bunch of delayed maintenances that didn't happen due to COVID-19; 2. a potential issue with welds in a safety cooling system which was found in 12 of the more recent reactors and required some unplanned shutdowns to investigate and (sometimes) repair.
delroth··on Companies are buying large numbers of carbon offsets that don’t cut emissions
> or it will get raised too high and be used to do something unrelated

That matters very little. Carbon taxation is a Pigovian tax, and just making emitting CO2 more expensive creates strong incentives to stop emitting CO2. It also makes "green" alternatives comparatively cheaper.

In fact, many proponents of carbon taxation support equal redistribution of the tax money to everyone (e.g. as tax credits). Taxpayers polluting less than average would see their tax burden decrease, while those polluting more than average would be paying more and thus be incentivized to change their behavior.

(Of course, it's not that easy in the real world, some behavior can be extremely hard to change without help/subventions/large investments. But these helps don't have to be tied to carbon taxation.)

delroth··on CERN drafts plans to idle accelerators due to Europe’s energy crunch
> Minor? Your link is outdated. EDF was forced to prolong the shutdowns recently [1].

Your link doesn't say anything about the severity of the issue, just the number of reactors it impacts (12, which is the same number I indicated).

> It will, but the drought is likely to reappear next summer

Sure, by then the welding issues are hopefully finally addressed (the plan is to have the maintenance done by January, but I strongly suspect this will slip by a few months) and then it's only the regular refueling which has been happening in summer for almost 50 years.

> which is why not just the spot electricity market is bananas but also the futures market

Well, no, that's due to a lack of electricity production capacity. Issues with the french nuclear fleet are part of that problem, but they're not all of that problem.

> even a tiny fuck up has the potential to irradiate a large region for decades

Absolutely not. Tiny fuckups happen all the time and have no consequence. Major fuckups happen once in a while and also have no consequence (TMI, for example). Huge fuckups have happened twice in the past 40 years, and only once with major irradiation consequences (Fukushima Daiichi has roughly no exclusion zone left at this point 11 years after the accident, the last town has been reopened earlier this year). The nuclear industry has learned from all these fuckups, from the tiniest ones to the catastrophic ones, and something like the issue at Chornobyl just cannot happen in France.

delroth··on CERN drafts plans to idle accelerators due to Europe’s energy crunch
> French nuclear reactors [...] offline because of massive defects

There's no "massive defects" involved, it's a combination of 1. regular refueling maintenance which happens every summer; 2. some maintenance being delayed due to COVID-19 that was finally able to be scheduled this year; 3. a minor corrosion issue [1] being found with the welds in one of the newer plants, leading the power plant operator to stop all similar plants for safety reasons to be manually inspected.

> barely producing due to a lack of cooling water

There's plenty of cooling water, it's just warmer than usual upstream of some of the plants, and the plants have rules about not rejecting water above a certain temperature to the river in order to protect wildlife. These rules can be waived and in fact have been waived several times this summer and previous summers to continue producing at higher load -- it sucks for the fishes that get +1°C, but we're basically making a choice between warming up the rivers or warming up the planet with more CO2 emissions. This is indeed the same situation as in Beznau (CH, the article you linked), but absolutely not comparable to the problems with hydro in Italy that are actually due to lack of water. You can't waive a lack of water.

> no indication at all that the situation in France will clear up any time soon

(1) and (2) are absolutely going to clear up by winter. https://nuclear-monitor.fr/ shows the planned maintenance end dates. Just by the end of the month EDF is planning to have 11-12GW back online [2] (though their maintenance end dates tend to slip up by a few days in general). That leaves the 12 reactors (out of 56) impacted by (3). I suspect that if it actually comes to blackouts, (3) might also clear out, if we decide that the minor safety risk of the welding issues is less bad than the people actually dying due to lack of power. Unfortunately anything involving nuclear safety makes people freak out and require 100% reliability, even when it's absolutely irrational to do so and causes more human deaths.

delroth··on Cloudflare's abuse policies and approach
The negative value of a website being serviced by Cloudflare is usually significantly higher than the price they pay for the service.

How much do you think Cloudflare donated for the 3 suicides caused by Kiwi Farms in the recent years?

delroth··on Who killed nuclear energy and how to revive it
In this specific case (regulations on the cooling water temperature) it's killing some fishes vs killing some birds. That seems very comparable to me.

Why wouldn't we require wind turbines to stop when birds are migrating to reduce their environmental externalities?

delroth··on Cloudflare stood up to a patent troll and won (2019)
Literally every individual claim in your message is trivially wrong.

1. The IRS is not involved, it's the department of state collecting these statistics.

2. Japan has been in and out of lockdowns since 2020 like most countries in the world, and nothing particularly changed in May 2021. If anything travel rules are laxer since then with most business travel and family visits being authorized again.

3. Your statistical claim that 15 months of no deaths (previous data: average 26 days between deaths, max 81 days) is plausible is beyond absurd. Please show your maths, I'm not going to spend time on my phone doing probability distributions for you at this point because you must be trolling.

I'm appalled that you're spending your time trying to convince strangers on the internet that my friend faked their death. Do you really have nothing better to do with your life than to shit on those who lost theirs?

delroth··on Cloudflare stood up to a patent troll and won (2019)
Neither is anyone since May 2021 (even though the data had an average rate of right 1/month before that). I guess the US expats in Japan have figured out immortality and aren't sharing. Or, maybe the data source is absolutely useless and incomplete?

delroth··on More invested in nuclear fusion in last 12 months than past decade
> building a fission reactor takes one or two decades

This is not universally true. Looking at South Korea's construction times for example[1], you'll see that it's averaging between 5-7 years per reactor, all the way into the 2000s and 2010s. Japan shows similar numbers[2], and they're currently in the process of restarting their nuclear investments following the accident at Fukushima Daiichi. Same story for China[3].

delroth··on Possible impact of functional active gpcr-autoantibodies in long Covid
Maybe? Reading the abstract, it seems to make sense to me how this paper ended up in this specific journal. From what I understand, the authors were specifically looking at one ophthalmology-related long COVID symptom (impaired retinal microcirculation) and found a common marker that is linked to that symptom.

Granted, I have 0 experience in any medical field, but it doesn't immediately look like a red flag to me?

delroth··on Ask HN: Has Cloudflare blocked your domain without explaining what's going on?
> You can in detail ask about ALL personal data that was used as an input for this decision, information about the ¨automated decision-making¨ (algorithm), and all personal data that resulted out of this process. https://gdpr.eu/article-15-right-of-access/

That is only true in specific cases of processing, as detailed by article 22: "a decision based solely on automated processing, including profiling, which produces legal effects concerning him or her or similarly significantly affects him or her".

In the case of a domain name used for email I think you could legitimately argue that the decision "significantly affected" you, but it's kind of undefined so far what the bar is for this criterion.

The update data is not redistributable, but there is nothing copyrightable in what the "fake update server" returns (30 lines of PHP serving some trivial static XML files).
delroth··on Should you make an open API?
> On the FAIRTIQ side, we do not support this authorisation model yet as we don’t provide an open API

So I guess the message from the article is "we love that others provide open APIs but we can't bother".

delroth··on Ask HN: Has anyone leveraged GDPR to overturn automated bans?
Not speaking for my employer, but the actual quote from GDPR is:

> The data subject shall have the right not to be subject to a decision based solely on automated processing, including profiling, which produces legal effects concerning him or her or similarly significantly affects him or her.

Emphasis mine. This would not include the vast majority of automated bans. It's more meant as a way to prevent e.g. automated police action via algorithmic selection.

Depends on the country. France doesn't usually check the ID when they scan the QR codes. Switzerland more often than not does, at least in the German speaking part of the country where I live.

delroth··on Trump’s new social media platform found using Mastodon code
> If the license doesn't achieve what the creator wanted, then they can just change it.

No, you can't "just change it" if you have external contributors and you allow them to keep ownership of their contributions (the default). Many people object to CLAs on philosophical reasons and will refuse to sign them.

Now your "just change it" is a 6-12 months effort trying to chase down every single contributor and nitpicking your license change until everyone is happy, or rewriting a bunch of code due to licensing issues.
