2143··on Firefox Keeps Getting Faster
I shut down my work machine at the end of the day if it has written to the swap space; else I just close the lid.

I always shut it down on Friday evenings though.

2143··on Scrambling eggs for Spotify with Knuth's Fibonacci hashing
I'm convinced something's wrong with Spotify's randomization.

When I press the big green play button in a playlist's page, it tends to start playing from a specific song, in a weirdly familiar order. So I manually pick a song at random and let it play from there.

But even so, some songs almost never get played, but others get played fairly frequently.

2143··on Show HN: Minimalist Calendars Generator
Looks neat.

Just wanted to add that on Linux/Unix (including MacOS), typing "cal" into the terminal also gives you a calendar. And there are arguments you can pass in to make it display a specific month or year.

2143··on What has changed in CPU cores in M3 chips?
For my personal machine I have a relatively new ThinkPad running linux that works perfectly well for everything that I do.

Ever since it came out I want to buy a MacBook with these new chips as my personal machine. But I haven't yet bought one because I don't need one.

Or I'll buy it when my ThinkPad dies. (Weird laughter).

And then over here I read about people replacing laptops every other year or so, and I wonder why I am the way I am.

2143··on datetime.utcnow() is now deprecated
> Why can't they, for instance, simply declare that school/offices open at 10am instead of 9am for six designated months every year instead of imposing this adjustment on the entire world.

Or, if you extrapolate this argument further, you could even wonder why the entire world can't run on a single timezone.

But here's the problem: for example, imagine it's UTC everywhere on Earth. No local timezones.

As per your solution, people in India can go to sleep at 4:30 pm (UTC), wake up at 12:30 am, have lunch at 7:30 am etc.

Likewise, people in San Francisco can go to bed at 6 am, wake up at 2 pm, have lunch at 9 pm etc.

Now, the problem is, when someone wants to setup an international meeting or whatever, nobody would have a clear idea or whether it would be "sleeping time" for any of the participants involved, without having to look it up.

Like, with the current setup, it's kind of universally understood that 3 am local time is sleeping time, hence people would avoid setting up meetings at that time.

But if everywhere on Earth it's the same time such as UTC, I would have no idea if 3 am UTC is your sleeping time or lunch time or whatever. I would have to maintain lookup tables of when the sleep time, lunch time etc would be for every country as per UTC.

Similar problems exist (to a lesser degree) when large countries move to a single timezone.

Yes there are flaws in the existing setup, but moving to a single timezone for large countries would only introduce a new set of challenges.

2143··on Why Japan has blue traffic lights instead of green
Just a data point that I want to put out there.

I have long heard that Japan has blue traffic lights.

Earlier this year I visited Japan.

Because I had heard about the blue traffic light situation, I paid special attention to the traffic lights.

They all appeared green to me. In both Tokyo and Osaka.

Okay maybe a tinge of blue if you look at it and wonder 'is this blue?', but the only reason I wondered was because I had heard the blue traffic light trivia. If I had never heard about it I wouldn't have given it a second thought.

However, the picture in the linked article seems to have an unmistakable blue color; I don't understand what's going on.

Beautiful country by the way; would love to visit again :)

2143··on This is financial advice [video]
I have always felt this is where recommendation engines go wrong.

If I watch a cat video, it'll think all I like are cats.

I may like content about Foo — something entirely unrelated to cats — if I watch it. But since I have never watched anything about Foo before (perhaps because I didn't know about its existence), it won't recommend me Foo. Therefore I wouldn't know it exists. Hence I never see it, even though if I had seen it I may (or may not) have liked it.

Meanwhile, after a point I get tired of all the cat videos, and stop using the service.

I want recommendation engines to occasionally recommend totally fresh content unrelated to anything I ever watched.

2143··on Tell HN: Consider waiting before upgrading to macOS Sonoma
I do this.

And not just for OS updates.

For example, I have noticed that if a new model (or generation of and existing model) of a car comes out, it's better to wait for a year or two for them to iron out the issues.

(No I don't purchase cars frequently; just an enthusiastic who keeps track of the industry).

2143··on EU tells Apple to open everything up to its rivals
I was wondering the same thing. This is the first time I'm hearing of lint-inside-port situation. Was I living under a rock?!

This has never been a problem for me for both USB-C or lightning ports. But apparently — judging by comments here — this is a common complaint.

About the ports themselves I don't care either way. I have no strong opinions about USB-C or lightning.

> University prof might not be a wealthy job, but class wise it is usually considered pretty high class. We're not exactly talking about the people putting 9-5 in doing manual labour at a construction site.

Ah, yes. Agreed.

> Maybe, but its still a large investment for questionable financial gain.

No no, I don't think you realize how cheap education can be where I'm from. Getting admitted is an entirely different matter. And don't ask me how, but here there's an inverse correlation between how good a university is and how expensive it is. Like, here the best universities seem to be run by the government and are therefore much cheaper than private universities. Which is why it is also very hard to get into those govt run universities.

Also — I think this is a cultural thing — generally people here tend to want go to college, even if ultimately there is little correlation between what they study and what they end up doing (atleast, for non-engineering non-medical courses).

And, college degree is kind of expected for any job here. I don't know if that's what's caused the cultural default of going to college, or vice versa.

So yes, lots of complex, and sometimes contradicting dynamics at play.

There are inefficiencies with such an attitude, but I guess it is what it is.

(And, I'm not an expert in any of what I said above, so take all of that with a pinch of salt.)

2143··on TikTok is changing the way books are recommended and sold
All of this is applicable to where I'm from (global south); don't know how it is in western countries.

> Don't you have to be fairly well off to invest the time to write a book?

No. I'm aware of plenty of critically acclaimed writers who are not particularly rich. (Although there are plenty of people who got rich because of the books).

I guess most of them have/had other jobs, like teaching at a university for example. And some — especially people who were university teachers — tend to continue on that job.

> Not to mention a probably strong correlation in higher education in an area that is not all that useful for getting a job

A college degree in things like literature, political science, economics, and general science subjects (physics, chemistry, math, biology etc) tend to be inexpensive here, as compared to a degree in engineering or medical science.

Okay, there's more diversity. But you immediately say this:

So which is it?

By the way, there's plenty of people from all over the world in the Netherlands :)

2143··on 100 Parking Tickets (2004)
I've seen the LNU variant — "Last Name Unknown".

In southern India it's common for the last name to simply be the father's name (but I do know one guy whose last name is his mother's name).

Like, my name could be "Foo", my father's name could be "Baz" so the given name field of the passport could be "Foo Baz", and the last name would be blank.

But the visa form for certain countries don't accept that, so they put in "LNU".

Anyway, these days people are more aware, so when applying for passport they specify the given name as "Foo", and the surname as "Baz" (parent's name), even though that's really not the surname.

2143··on Ask HN: Any good school timetable apps for Linux?
Assuming that the timetable stays static throughout the year, create a document (using LibreOffice Write, Pages, Docs, Word or whatever it is that's available), insert a 8×5 table, and populate it.

Cannot possibly be more straightforward than that.

Pro tip: share it with your classmates!

PS: why do you need an "app"? Do you need to tag homework/reading schedule to it?

2143··on Organic Maps
I hope so. I first heard about it (from this very post on HN), downloaded, and installed the app all within the past 1 hour.

And when I zoomed into my city, it downloaded the map information.

2143··on Organic Maps
openstreetmap.org correctly displays the islands and the relative distances between them!
2143··on Organic Maps
Great app, I like it, but I did notice some problems:

My city is comprised of several islands, and there's relatively large bodies of water between them (over 100 metres), but this map shows those large water bodies as narrow (1 or 2 metre) river-like things.

I understand this might be the problem of the underlying data source, and not the app itself.

(For what it's worth, both Google and Apple maps correctly displays the islands and water bodies).

Over here (large country in South Asia) it's three phase by default.

You can get single phase upon request, provided it's a really really small house, shop etc.

> One time I asked a web dev friend of mine what he thought of Kubernetes and he didn't even know what it was. This was just a couple years ago. I was shocked at little he knew and how much he got paid.

Not be a good heuristic. Maybe they're in a job where they don't have to use Kubernetes.

Like, I know compiler developers who have no need to bother with Kubernetes.

> But does a C student web dev who kinda doesn't give a shit really deserve 150$k/year?

In college they might have struggled; some people just don't work that well in a classroom environment. That doesn't necessarily mean they're idiots. Or maybe they improved afterwards.

Just because somebody got an A in classroom tests doesn't necessarily mean they should be the most-compensated.

The real world is complex.

2143··on Interactive Hiragana chart with audio
I know absolutely no Japanese letters. And FWIW, I also know absolutely no Chinese/Mandarin (btw are they the same?), Korean etc.

I speak two languages — English and another language you probably haven't heard of that does not use English-looking letters (such as "a", "b" etc).

Anyway, provided I'm told that a given text is Japanese, I can tell if a letter is Kanji, Katakana, or Hiragana.

Which I think is commendable — if I may say so myself — given I didn't even know about the existence of "Kanji", "Katakana", or "Hiragana" until 3 years ago.

2143··on Conferences are inadvertently excluding many attendees from foreign countries
> I know a few people who are travelling to Europe and they're getting single entry fixed dates visas every time

I thought you were talking about visas to the US. How is people "travelling to Europe" relevant?

> Have you ever been on a visa interview in US embassy?

Yes I have. Twice. For two different visa categories at separate points in time.

In both cases my interview with the consular officer was very pleasant and took less than 5 minutes, and the first time he even said "enjoy your trip!”.

Now, I know a lot of people's US visas get rejected for whatever reason. I don't know why that is. Nor do I know why it was easy for me and difficult for others.

> Higher salaries, better job market, better living conditions, you name it.

> US immigration system is so fucked up there is no proper way easier than crossing Mexican border and legalizing as a refugee. Or "disappearing" on tourist visa.

My previous post was about whether or not it's harder for non-Americans to apply for a US visa from Europe. I was not talking about the general immigration situation in the US.

Rhetorical question — if a non-American non-European were to sneak into America via Mexico, why would they go to the trouble of settling into Europe first?

This is borderline flamewar, for no good reason. I wouldn't be replying further. Have a good day.

> If you moved to some country in Europe is is _harder_ for you to travel to US, and vice versa.

No it's not.

Anecdata: plenty of Indian citizens in Europe go troublefree to the US.

I personally know a few people.

> Second, as you've already taken the immigration route once, you're seen as a potential immigrant with a risk of no return.

You make it sound like they would illegally-immigrate to America.

Why would someone who's legally present in Europe (and presumably tax-paying) sneak away to America?

If such people want to immigrate to America it's fair to assume they would do it the proper way (instead of going there on a tourist visa and disappearing).
