fer··on 64-bit bank balances ‘ought to be enough for anybody’?
I've seen floats for money in production, not a financial system per se, but it moved amounts around external systems that often would include some financial ones. It worked surprisingly well given the amounts involved (anywhere from tens to thousands of EUR/USD), and when I asked about the off by +-0.01 errors every now I was told they were "not worth fighting by the customers".

I think that's been the case for a while other countries' marketplaces.
fer··on Ask HN: How to handle Asian-style “Family name first” when designing interfaces?
I assume you're talking about Société Générale? I've experienced that, and what's worse it's that's it's broken on purpose. A joint bank account doesn't require the people to be married, let alone to share names. But if they tick the married box, whoops, now it's suddenly mandatory.

If you obtain French citizenship you can "francify"[0] your name; you'll end up with two full canonical names. Nothing really forces you to change your original name in your original nationality.

fer··on Ask HN: How to handle Asian-style “Family name first” when designing interfaces?
In France married women, if they let their guard down, will be given their husband's last name as "nom d'usage" upon almost any sign-up paperwork, without being asked, at least in my experience.

Nom d'usage technically has no legal value, it's just a last name you might want to be addressed as, normally that of your husband but it can be a pen name and whatever. It's optional, and technically only at the request of the relevant person. Men can have nom d'usage too (égalité, after all).

Still, immigration offices, banks, insurances... they often slap the husband's last name if that field is left empty, just because. Why would you want something else, right? She probably forgot!

We started crossing those fields to make it clear she doesn't want a nom d'usage.

fer··on Past Covid infection protection against re-infection: a systematic meta-analysis
Are you aware that this study doesn't really support any of what you said?
fer··on Past Covid infection protection against re-infection: a systematic meta-analysis
> The difference is that flu vaccines actually prevent infection in many cases

OK

> whereas COVID vaccines do not prevent them, but merely lessen the symptoms and risk of hospitalization.

Is this something I can read on a peer reviewed study, or is it yet another creative definition of what "infection", "vaccine" or "symptom" really means?

fer··on Past Covid infection protection against re-infection: a systematic meta-analysis
> The only difference to the population that I see is that vaccines for COVID have less efficacy than those for influenza.

So far COVID vaccines seem to confer protection for longer than flu ones, and the initial protection is generally higher.

Not sure if it's your case, but people often forget that every year there's a new flu shot per hemisphere, and its effectiveness generally hovers at around 40-60%.

tbh, I always assumed it wasn't implemented yet; it never worked for me

fer··on Screen Apnea
Maybe I'm wrong (not a doctor), but I believe it is very unlikely that one off events of apnea lower your saturation to a level of clinical relevance to need 2s frequency; saturation drops only after a continued chain of such events or some sort of constant obstruction (COPD, asthma exacerbation, etc).

Also, though sample of n = 1, training for freediving my breath holding PR is 3m31s, and my SpO2 barely went down. The CO2 reflex kicks in before O2 goes significantly low.

fer··on English is a pictographic language with 26 radicals
If by true phonemic you mean 1:1 relationship between sound and letter, sure; not all the letters sound the same all the time, and not all sounds are always represented by a single letter. It's a natural language so it's bound to have some irregularity.

But those exceptions you listed are either rare exceptions (h is always silent, but with a handful of exceptions, normally loanwords like hámster or hachís; x is always "ks" except in old/historical words like México or Quixote), or just follow more or less complex rules.

In general if you read and know basic rules, you know how to pronounce 99.9% of the time, if you listen you need to have some deeper level of orthography/etymology/grammar knowledge to write correctly.

fer··on English is a pictographic language with 26 radicals
In case someone's curious, it's not only Spanish, and it's certainly not unusual[0].

A way to see how a (more) phonemic orthography would look like in English is to have a look at BBC Pidgin[1], though the increased "phonemicity" isn't the only difference.

fer··on Driving is more expensive than you think (2020)
My mom's (then) boyfriend sold his car back in '96. He was a science man but not on a particularly number-hard field (veterinarian).

He still ran the numbers.

I was too young to fully understand but basically accounting for every cost it was cheaper to call a cab or rent a car for every situation that actually requires a private vehicle, plus it saved loads of time overall (repairs, maintenance, checks, cleaning...) and headaches in general.

The discussion stuck to me, and I'm always amazed at how it became a realization for so many people decades after.

Granted, this was Western Europe where public transit is ages ahead of most of the US.

fer··on Ubisoft account -including games- can be permanently deleted for inactivity
Not whom you reply to, and maybe a bit of an exaggeration, but yeah. My account is from Sep 2003, I have around 300 games there (mostly from Humble Bundles), by 2012-2013 I almost stopped playing. Then I had a phase where I put maybe 100h in Rocket League to play with friends back in 2017, then 2021 to play Outer Wilds[0].

That's pretty much it. I still want all of those games, thanks.

fer··on Nanosecond timestamp collisions are common
Fun fact: a ping from the center to the extreme of the milky way would overflow for 64 bit millisecond timestamps.
fer··on Nanosecond timestamp collisions are common
I have a use case that uses a similar solution, but for a different reason: it doesn't scare me to use timestamp as sort key I since I know my hash keys are unique and I only write every few seconds. But I still add random amount of ms (well under the frequency of writes/updates), because otherwise I'll be hitting hot partition issues on the GSI (indexed by timestamp, as you can guess).

spez to the investors:

Joking aside, I have a few bots monitoring content and I saw ~10% drops in comment activity before the outage (vs. the baseline from last week).

fer··on Weird GPT-4 behavior for the specific string “ davidjl”
It's just a language model.

I've asked it to prove the Riemann hypothesis, GPT-4 replied it can't, since none of the training data say anything about such proof.

Then I asked it to prove statements of the implications of said hypothesis (I tried 2 or 3, don't remember which), without calling them by name or mentioning Riemann, and it confidently proved them in a way that it reads like it knows what its doing, though it really doesn't. It just takes bits and pieces from proofs in the same field of mathematics that kinda hold together language-wise.

fer··on I ditched my car – and improved my fitness, sleep and bank balance
> I live in Dublin, which is at least in Europe so better than many US cities, but certainly not very good on bike infra.

I live in Dublin and maybe you're comparing it with Amsterdam, but having as reference 3 EU capitals I've lived in before, Dublin is bike path heaven. 100% of all the area I usually move around has bike paths, and even in areas without, drivers are generally aware of cyclists because of this.

If anything I'd complain about certain hostility towards pedestrians, rather than cyclists. Traffic light timing is abysmal and in some crossroads a pedestrian can be waiting for solid 5 mins while cars have had 2-3 rounds of green lights.

> What are the statistics on lithium-ion battery failures? Are they dangerous full stop, dangerous in certain scenarios

If you wanna get more paranoid: https://www.reddit.com/r/spicypillows/

Jokes aside, hard to say, but it's mostly scenarios.

Some batteries have proper venting (or puffing), protection circuits and sensors to prevent thermal runaway, and they are very unlikely to fail catastrophically, they would stop working before, generally.

Now those take more space, so such features are often offloaded onto the PCB designers to make them fit, and you may trust them more (or less) than the battery manufacturer.

More or less the same can be said about the charging circuit, and how it might handle low voltage or trickling/stop charge.

Personally I've seen flashlights that burn through the 18650 without respecting the minimum voltage whatsoever, and that would put 5V to charge. There a proper battery will refuse to charge or just die, but an unprotected one might catch fire.

As anecdotal data, after dozens and dozens of devices, I've only owned two batteries that became spicy (without catching fire), a Chinese-brand laptop and a cheap quadcopter battery.
