newaccount74··on Swift 6
I think the goal of Swift on the server, or embedded Swift, is mainly to offer Mac and iOS developers a way to write everything in the same language.

Right now, my Mac app depends on a few simple web services that are written in a different language. It would be neat if those services could be written in Swift, so that I could just use the language I already know instead of relearning how to do decode JSON in Python/Ruby/PHP.

Swift on the server doesn't have to become widely used. As long as there is a simple way to write basic web services, it is useful.

Please re-read my comment carefully. I never claimed undergoing an MRI with metallic implants was safe, in fact I stated the opposite: "A force will act on them, and this force can cause complications"

The only thing I strongly disagree with is the urban myth that MRIs turn implants into projectiles. I don't think that can happen. None of the videos you linked show anything of the sort.

Yes, objects can be accelerated to dangerous velocities; but only if they can move freely (eg. oxygen bottles on a cart, wheelchairs, small objects placed on a smooth surface). Objects embedded in tissue can not move freely and won't start tearing holes in your body like reverse bullets.

It can of course still be dangerous. One lethal case documented in the literature involved a metallic clamp inside the patients head. The MRI seemed to have moved or dislodged it causing cranial haemorrhaging. It killed him, but it did not shoot out of his head like a bullet.

newaccount74··on How to succeed in MrBeast production (Leaked PDF)
It really depends on whether the capacity is fixed or not. If capacity is fixed and demand is unlimited (eg. because you just can't get more EUV light sources this year) then you should probably run as close to 100% utilisation as possible.

But if you can easily scale production capacity, you should not strive for 100% utilisation. You should expand capacity before you reach 100%, because if you are running at 100% you will not be able to take any more orders and lose the opportunity to grow your business.

I think following through on the crazy thumbnail is the most defining part of the MrBeast brand.

Lots of Yt videos have crazy thumbnails; only MrBeast follows through!

newaccount74··on DiyPresso: DIY Espresso Machine
Espresso machines are made from copper, brass, and chrome. The chrome plating typically comes off quickly from the filter handles, exposing the bare brass to the coffee. All that stuff ends up in your coffee (where else should it go?). This means that espresso is pretty much guaranteed to contain copper, zinc, lead, chrome, nickel.

I'm not sure that is safer than the microplastics or aluminium from coffee capsules.

Fully stainless steel machines are probably the best option, but there are very few of those around (and they would probably still leak nickel).

MRIs don't accelerate objects instantaneously. If you look at the experimental setup, you'll see that they placed objects inside a pipe that allows them to accelerate with very low friction.

Implants inside the body cannot accelerate freely. They are held in place by the surrounding tissue. A force will act on them, and this force can cause complications, but implants will not suddenly turn into projectiles.

newaccount74··on Another police raid in Germany
Here's a different take:

Criminals and fraudsters will abuse pretty much every technology they can get their hands on. As a consequence, every service operator needs to do their part to prevent fraud and abuse. If you offer a service anonymously and indiscriminately, your service will be overrun by crooks, and you'll end up serving criminals.

The fact that your service could be used to defend free speech does not absolve you from your duty of monitoring the use of your service. If you realise your service is used for exchanging illegal content and bomb threats, it's your duty to do something against that, or stop providing the service.

newaccount74··on Another police raid in Germany
I really don't get how bomb threats can be considered "speech". Like, there is no benefit to society from allowing people to make bomb threats.
newaccount74··on Common mistakes when using the metric system
I disagree with that rule. I get that people spell liter, gram, meter in lower case, but units based on names of historic persons like Volt, Ampere, Coulomb, Pascal and Kelvin deserve to be capitalized.
newaccount74··on Nikon sold more Z9 cameras in its first year than any flagship in past 15 years
Did they fix autofocus in the X100 line? I had an X100T, and the multi-point autofocus somehow focussed on the wrong thing 50% of the time.
newaccount74··on Nikon sold more Z9 cameras in its first year than any flagship in past 15 years
A high end camera is probably one of the least wasteful electronics products. They last at least a decade. Just a few weeks ago, I sold my Nikon D70. So even entry level DSLRs stay useful for 20 years. There are few products with such a long lifetime.
newaccount74··on Ask HN: How do you organize work as a solo developer?
Here's my experience from the last ~12 years as a full time solo developer:

1. I use Github issues to track features and bugs that I am working on. It's useful because sometimes I come back to a feature months (or even years) later, and I don't have to start from zero again.

2. I've tried a lot of systems for planning work, but I found nothing that beats pencil and paper. Plans always change anyway, it's good to just spend 5-10 minutes planning your day before you start working.

3. It doesn't matter if you move back and forth, change priorities, etc, as long as you keep making progress. You only find out after the fact which of the features were the ones that really made a difference.

4. At some point I realise that I'm getting close to a release, then I switch into "release mode", I stop working on new features and just fix bugs until the release is done.

newaccount74··on Ask HN: Where are the part-time remote coding jobs?
I'm not sure how health insurance works in the US.

In Europe, health insurance and social security is just a percentage of your wage. So for the employer it doesn't matter how many hours you are employed, taxes and health insurance is just a percentage.

I was under the impression that in the US health insurance is a fixed cost, that depends mostly on what is covered, but it doesn't depend on the income of the individual. So if an employer offers health insurance to part time employees, the cost would be the same as for a full time employee.

newaccount74··on Ask HN: Where are the part-time remote coding jobs?
For cashiers, hiring two part time employees is preferrable to one full time employee, because you can have their shifts overlap to cover peak hours. It's the reason why cashier jobs are almost all part time. They don't hire full time cashiers because then they would be overstaffed during slow times of day.

For any job that requires coordination, there is a huge communication overhead when hiring multiple people. It's extremely inefficient to split work between multiple people, so companies prefer to hire people for as many hours as possible.

The only way a part time softwate job would make sense for employers is if the job is so simple it needs no coordination, and two part time employees would be cheaper than a full time employee.

I also suffer from irregular, unexplained headaches. Someone must be microwaving my apartment complex.
newaccount74··on Thoughts on the Durov Arrest
This is quite a one-sided take.

What makes Telegram unique is:

1) They have access to almost all the content

2) They try to use arguments about jurisdiction to avoid helping law enforcement with lawful requests

All the other messaging platforms (WhatsApp, Signal, iMessage) have started to use end-to-end encryption to avoid being in this position in the first place. But they also comply with law enforcement and share the data they do have, and don't hinder lawful investigations.

The biggest issue with Telegram is that due to the lack of end-to-end encryption it is a huge security risk; how do you know the operators aren't selling access to your chats to some criminal actor or a repressive government agency? You don't.

newaccount74··on Your Immune System Is Not a Muscle
Allergies seem to come and go. My partner developed allergies against many local fruits in her early twenties, to the point where she could barely eat any fresh fruits without her lips and throat swelling up; but most of them subsided in her 30ies and she can now eat almost all fruits again with only minor irritations for some.
newaccount74··on The Triple Failure of 2U, EdX, and Axim
why can't online universities have TAs like real universities? Pay for a course, have someone who completed some more advanced course grade your work or provide one-on-one feedback!
newaccount74··on Lidl's Cloud Gambit: Europe's Shift to Sovereign Computing
Yeah, I feel that a lot of EU projects work that way.

I've participated in a bunch of EU projects in the academic space. Most of them were catastrophic failures if you just looked at the direct outcomes (few of the lofty goals were actually achieved). But they did provide much needed funds to participating institutions, and I think they were an overall win.

They come with a lot of overheads (some had 10% or more of the funds go to a lawyer who managed the project). But they are a lot more effective than all the "unbureaucratic" Covid aid payments that mainly went to companies with close ties to political parties...

newaccount74··on Study: Air purifier use at daycare centres cut kids' sick days by a third (2023)
Most low-level infections probably go unnoticed, and won't show up in the study at all.

Some days the kids are just a bit off, and taking their temperature shows slightly elevated temperature (37.2°C in ear). I'm pretty sure they are fighting some mild infection, but they aren't really ill.

It's a more friendly way of saying "trust noone".
newaccount74··on Magic Wormhole: get things from one computer to another, safely
The difference between log 2, ln, and log 10 is less than an order of magnitude, so to a physicist it's all the same :)
newaccount74··on Ask HN: Why are AI generated images so shiny/glossy?
Those photos look impressively realistic, but the skin has exactly the wax-like sheen that I think OP is talking about.
newaccount74··on Is running a more efficient way to travel than walking?
7 min mile is one kilometer in 4:20.

You need to be pretty fit to run that fast, especially over longer distances.

newaccount74··on The Marshmallow Test does not reliably predict adult functioning
> people becoming increasingly skeptical of "hard science" conclusions

A big problem is that "hard science" conclusions often only apply to very specific circumstances, but scientists and the general public then extrapolate to more generic situations. The consequence is that a lot of things that are supposedly based on "hard science" aren't really proven at all, it's just someone making educated guesses.

newaccount74··on FakeTraveler: Fake where your phone is located (Mock location for Android)
What I am trying to say is that there is no strict difference between "user interests" and "corporate interests".

Companies in general don't want reliable data for the fun of it; they want it in order to provide services that users want.

newaccount74··on FakeTraveler: Fake where your phone is located (Mock location for Android)
I think you are stuck in an "us vs. them" mindset. It's not all consumers vs corporations.

Consumers actually want to use services offered by companies, and willingly accept what you consider drawbacks. We want accurate traffic data in maps, and crowd-sourced key finders, and all the other conveniences afforded by unspoofable location data, and we give up a little bit of control in exchange for that.

Companies don't compensate us with money for crowdsourced data; they compensate us by offering services they couldn't offer otherwise.

newaccount74··on FakeTraveler: Fake where your phone is located (Mock location for Android)
Users also need other users to be honest about their location. Consider a dating app; you want to meet real people who live in your area, not a fraudster pretending to live just a few blocks away.

Or a delivery driver: You want them to actually drive up to your house and ring your bell, rather than just pretend to drive there and drop your package somewhere else.

Location data is worth a lot more if it is reliable.

The user should be in control of sharing their location. But you shouldn't be able to just provide a fake location.

newaccount74··on FakeTraveler: Fake where your phone is located (Mock location for Android)
There are a lot of legitimate use cases that require reliable location data. I mentioned a few that I could think of in a sibling comment, but I'm sure there are more. Maybe you can come up with a use case for accurate location data yourself?

Anyway, spammers and data brokers probably wouldn't care at all if say 10% of people spoofed their location. They don't really have a lot to lose if some of their data is incorrect.
