Has anyone here self-taught themselves math in later life?

I studied up to A level (aged 19) but honestly started hating math aged 16 after previously loving it.

It’s a big regret of mine that I fell out of love with it.

I self taught myself coding and Spanish and much enjoy self study if I can find the right material.

Any suggestions?
> The idea that piracy helps audiences find and then buy the stuff they like, is also, for the most part, wishful thinking.

You are thinking logically.
Humans are NOT logical.

In some other countries,
Politicians hold huge banquets right before election day.
Lots of people eat at these banquets.
They could go vote for someone else after eating the free food because it is a secret ballot.
However, overwhelmingly those who got to eat the free food will vote for the people who reliably show up to feed them every election.
Why?
Because humans are not logical.

Same applies here.
You'd think people have already gotten free books or music or whatever.
But if they like something, they want to be a part of it.
Even if they don't personally pay for it,
If they really like it, they will share it with others.
Who in turn will likely pay for it.

Also I remember something profound I read when I was younger. The opposite of love isn't hate, it is apathy. The fear for anything that is worthy of copyright isn't piracy, it is being irrelevant and forgotten, out of the zeitgeist. If piracy can keep something relevant, it is worth the cost.
So when did they start using these and why are we still having issues?
Interestingly, according to the report in your link, UPenn pays over 3 billion dollars in salaries, but it has around 1,400 faculty for ~10,000 students. This means that either the instructors are fabulously well paid, or that the vast majority of money is going somewhere else. And indeed according to [0] just 4.64% of salaries are paid to instructional staff, with 23.9% or 2078 of paid employees being management staff. So if I am reading this correctly, they have far more administrators than actual academics, which is rather incredible. Incidentally, according to the same link the median percentage of salaries paid to instructional staff is 30% for similar doctoral universities.

I live in England, so there are already bike lanes and such, they're just not as widespread as I wish they were and its almost always part of a car lane or a pedestrian lane
> How much does the entertainment system in your car cost vs an iPad? Is that a rip-off, or is it a niche, custom part that has to be made from automotive grade components?

You can't say it's a niche part when the item is being manufactured in the hundreds of thousands or even millions. Car companies reuse components between models and sometimes even between brands.

And that's without mentioning that the average 7-8" screen or CPU in a car's entertainment system isn't a custom made part, they are bought at bulk from other manufacturers that produce (tens of) millions of units per year.

You can find entertainment system replacements for most cars that cost a fraction of what the car manufacturer charges consumers.

I struggle to see how a mass-produced, way more expensive (for the customer), lower-quality product isn't simply a rip-off.
My student loan in Sweden (I maxed it out at over $30k total for 5 years) had an interest rate of below 2% for the whole period. Currently it's just above 1%. The student loan interest rate is fixed to a small amount above the interbank rate.
The key is 1) I didn't have to borrow for tuition, just the books and noodles. 2) the state lends me the money, I don't have to fish around the loan market.
> Bike lanes are everywhere in most big cities in France too... But they're bad, very bad.

We once cycled from Germany to Colmar in France. Cycling through Colmar is indeed a scary experience, especially if you have a trailer with a small child in it: https://maps.app.goo.gl/wJU4GLWrmqF9EDes8

Of course it isn't much better in Germany.

Very cool. Consider crediting your niece as an author in the metadata? Don’t see it, but may give her a kick.
It's also really annoying at a roundabout that you can no longer see through the car next to you.
It wasn't the majority of queries until the past 5 years though. What was once an annoyance became an active disruption to getting the information I'm looking for.
Is that how "family income" in this context is calculated in the US? That until I'm married I count as being part of my parents' family but as soon as I marry I have my own? No age restriction or consideration whether I live with my parents or anything?
I'm still failing to understand why the urbanism departments are so bad in councils of even our big metropolitan areas. We could just contract with corps like Copenhaguenize to get to the state of the art right away when rebuilding roads, but "on a des idées" so why not improvise? Or it's just corruption and favoritism...

Nice project though, might ping you for something related :)
> because the stakes are actually lower.

I'd actually disagree there. The stakes for military aircraft are higher - assume Russia or China sends a nuclear bomb equipped squad on their merry way to Alaska.

If even one of the US planes has an issue taking it out of the fight, the Russian bomber squad may succeed, dropping a nuke and killing tens of thousands of people.

Seems that JuiceFS have S3 gateway, so you can still access the files in S3 protocol.
I have never been sympathetic to the notion that copyright has just been extended too long. Copyright itself is the problem. For example, for an academic from a poor region trying to keep up with publications in his field, even the short length of copyright set out by the American Founding Fathers, is too long.
Rock-paper-scissors also gives rise to scenes that are bad for naive sorting (for graphics or CAD), where you have three objects such that any two can be sorted in occlusion order, but not all three.

Can we triage our ikigai such that I (sympathising with my machinery) take all your overly-associative structures and you (communing with the universe?) take all my insufficiently-associative structures?

(there are many in maths: eg topologies, being families of sets, can be represented by a particular magma)

Isn't it funny how part of the solution is a bit like introducing a one-car buffer into the queue, reducing back pressure? Makes me wonder how much traffic planning and distributed systems could learn from each other (or perhaps already have, I'm not an expert in either).
This.

Sure, there's persistence but it always seemed like an afterthought. It's also unavailable in most hosted Redis services or very expensive when it's available.

There's also HA and clustering, which makes data loss less likely but that might not be good enough.

For the people wondering who would ever use Redis this way, check out Sidekiq! https://sidekiq.org/ "Ephemeral" jobs can be a big trade-off that many Rails teams aren't really aware of until it's too late. Reading the Sidekiq docs doesn't mention this, last time I checked, so I can't really blame people when they go for the "standard"/"best" job system and they are surprised when it gets super expensive to host it.

A few months ago there was a rather funny article in a French film magazine (cahier du cinéma). The director of a film school was complaining that his students obviously didn't know how to pirate films any more, so they couldn't get hold of classic films.
So he found himself with a population of film students who had practically only seen blockbusters from the last ten years. They had tried to set up a media library with DVDs and Blu-ray discs, but with the disappearance of physical media and disc players, it was no longer working.

The director was quite bitter. The fight against piracy has therefore rendered auteur movies invisible and has only benefited Hollywood.

Although this was in the '80s I remember that I (Dutch) walked to school at the age of 5, in a town (technically a city (Enkhuizen)), mostly through a pedestrian area but I had to cross one busy street.

My parents told me later that they secretly followed me the first few times (I never noticed).

Just try to image that you live in a country that is so safe you can let small kids walk to school. Try to imagine what a society could look like if it's designed for people first, not traffic.

Try this remarkable book:

Who Is Fourier?: A Mathematical Adventure

It started off as a bunch of non-math literate folks teaching themselves math from scratch, including trigonometry, calculus etc, and ending in Fourier series. It is a very approachable and fun book.
I never like these hard cut-offs. We should establish a name/expression for all these rules a simple wording which represents 200k=0% and eg. 250k=100% or something.

This is only a problem if you naively undersample the normal maps in your fragment shader. No AA algorithm can can generate a high quality result from undersampled lighting calculations.

For normal maps specifically, you can preserve lost information from downsampled normal maps as roughness: https://media.steampowered.com/apps/valve/2015/Alex_Vlachos_...

MSAA also doesn't require you to have only one color sample for each pixel but this can be varied per draw call (at least for desktop GPUs) - effectively allowing you to supersample some objects when needed.
> complete failures on their fixed price contracts

In fact, Boeing has stated they will no longer bid for fixed price contracts at all. They are institutionally incapable of making money by simply selling a product to the government for a price agreed to up front. Other companies can, but Boeing cannot. It's a rotten company.

https://arstechnica.com/space/2023/10/boeing-says-it-cant-ma...

Cost-plus contracts should be emergency measures for wartime only. They should be illegal otherwise. They hurt our country, not just by getting the government scammed by greedy corporations, but also by ruining companies like Boeing that should otherwise be competent and valuable assets to the country.
If your application is happy with an empty Redis, then why run Redis in the first place?

What you say is good in theory, but doesn’t hold in practice.

We use memcached instead of Redis. Cache different layers in different instances so one going down hurts but doesn’t kill. Or at least it didn’t when I was there. They’ve been trying to squeeze cluster sizes and I guarantee that’s no longer sufficient and multiple open circuit breakers happen if more than one cache goes tits up.

You'd still need to pay for the certification and audit trail paperwork, and in addition you'd take a part that has already been certified and replace it by a new one that would need to undergo the same certification requirement.

> weight is the enemy, the other is simplicity, : if its not there, it costs nothing, and cant break

Indeed but then you get crews taking their own soaps because they (think they) need to have soap aboard, store them wherever it is convenient for them, and the soap bar then gets loose and flies during the cockpit during a mission because no one thought about securing the soap as it isn't on any checklist.

That is also the reason why even brand new airplanes rolling off the factory line still have ashtrays in lavatories despite smoking being banned for decades now. They account for some dumbass thinking they do need to smoke and better they drop the cigarette in the ashtray (because that's what people do naturally) when the fire alarm goes off, than they dump it in the trash bin, causing the cigarette to set the trash alight and causing a bigger issue.

That is "fail-safe by design". Even if it adds 100 grams per plane to have that ashtray and a bit of work for the attendants to check if it needs to be cleaned out and for the pilots and maintenance crew a bit of work in the MEL check, it is still worth it over losing an aircraft due to a trash bin fire (and yes, that still happens, see the source for this quote!):

> As with just about everything on a plane, it's about safety. "They're there so if someone were to break the rules, they would dispose of the cigarette in the ashtray as opposed to, say, a trash bin full of flammables," says Robert Antolin, chief operating officer at App in the Air. [1]

At such cost with such narrow advantage, why has it persisted so pervasively? I would counter that the advantage is wider and the cost narrower than your current value system is allowing you to accept.

> Great to see additional public money to be spend to enrich private investors due to the German nuclear phase out. The 400 billions from the Energiewende are indeed not enough when we see the current carbon intensity of the country. #irony

As the nuclear plants were also owned and operated by private investors, I don't see why the German people shouldn't be allowed to say that they don't want nuclear power in their backyard. This certainly set back the climate goals of the country as did Putin's war of aggression in Ukraine.

400 bn EUR is indeed not a lot if you consider that it was spent to be part of an effort to kickstart solar and wind industries. Which worked and delivered a downward trajectory for LCOE which put solar, wind and soon batteries on the map.
I'm not talking about Go itself, I'm talking about building an API. All this talk of "string vs type" is not the solution to the root problem - sure, types can be better to return but what if the type changes? You still have breaking changes.

Whilst it is 95% calories in calories out, keto (not low carb, as low carb doesn't include high fat) can be good for muscle retention whilst in a defecit - as more foods that you consume naturally have higher protein (I utilise keto when looking to drop body fat, consuming a lot of slightly higher fat cuts of meat as a replacement for the carb calories, so chicken thighs instead of breast, 10% ground beef,etc). The higher fat content correlates to higher testosterone count, and higher protein means greater muscle retention.

Never again she said. It's a lovely country but the cycling infrastructure was ... questionable to say the least (according to her).

> Humans keep insisting that AI art is hideous slop. But also, when you peel off the labels, many of them can’t tell AI art from some of the greatest artists in history

I think there's a couple of reasons here.

1. AI art has existed for just a decade. Good AI art has only existed for a couple of years. People have experienced a lot of genuine AI slop over this time.

2. Even now when AI can generate good art, most of it is slop and there's just so much of it. Most people's experience of AI art is by seeing thousand of pieces of slop with a few good ones in between, unlike the art in this survey which is a careful selection.

3. Most people are just not that interested in seeking out AI art or forming opinions about it so they follow the herd opinion which is largely formed by artists who are worried about their livelihoods.

4. The pieces of AI art chosen in this survey were all picked to be not obviously AI. In other words, it's not even close to a properly chosen random sample. If it was, there would have been a lot of obvious slop in the survey and people would have been much better at identifying it. But then it wouldn't have been half as interesting and it wouldn't have been possible to write a series of articles being surprised at how bad humans are at identifying AI art.
lol well you, on the other hand, sound like the real deal! direct personal experience unlike all those posers, right? except why do you keep bringing up your friend then?

This is a really stupid argument, your data point of "one friend" or even two or more friends with unspecified timeline is useless. The only thing that has any meaning is a formal study with a large number of participants over many years of observations.
The difference is higher pixel densities and being able to have subpixel dithering with msaa buffers.

Other neat tricks with uvx (uv equivalent of npx) to run one time commands in some contexts:

- alias download_mp3="uvx --no-cache --from yt-dlp[default] yt-dlp --extract-audio --audio-format mp3" to download sound from Youtube videos, SoundCloud pages, etc. This update yt-dlp every time, which is required given the counter measures change so often and the dl rarely affect the total processing time anyway (requires ffmpeg).

- "uvx --with <package> --with pyqt5 --from qtconsole jupyter qtconsole" starts a qtconsole (GUI version of ipython) with <package> installed so you can test it quickly. Temp venv, everything cached so next time it's instant, one single copy of pyqt5 for the current use no matter how many times you run those.

- "uvx --with virtualenv pipx run pipsi install nodejs-bin". Ok it's useless, but it's fun that it even works :)

uv's cache system and downloads optimization are quite smart, as Charlie marsh (astral CEO) explains in the interview: https://www.bitecode.dev/p/charlie-marsh-on-astral-uv-and-th...
Dirty great walls - which some of us are on the "wrong" side of ;-)
I'm not sure how common this type of intersection is. I live and bike daily in Amsterdam and it took me about a minute to fully understand what's going on here. The picture seems to show a special case where the intersecting road is bike only, and instead of the normal painted arrows that show where bikes should queue up when making a left, there's an open area off to the left where one would wait behind the "shark teeth".

FYI if you are ever biking here in NL, the thing to remember is that if the "haaientanden" point at you, watch out!, as that means you do not have the right of way.

Edit: The side roads are for cars as well, which means you have a strange turning lane in the middle of the intersection where traffic might back up. A simple roundabout seems like a much better solution here unless the goal is to keep cars moving quickly and the turn lane is rarely used.
How much of this bonus will be clawed back in bankruptcy proceedings ?
> My parents told me later that they secretly followed me the first few times (I never noticed).

Ha, not in the Netherlands, but we started doing exactly the same with our 5-year old recently. She wanted to walk to a friend's house alone a few weeks ago and my wife followed her in spy-like fashion to make sure she arrived safely. We also started dropping her off a few blocks before kindergarten so that she can walk the remaining distance "alone" (again secretly followed).
> slavery or something similar (serfdom etc.)

Serfdom is very different from slavery. Even slavery is not always as bad as Roman slavery.

Roman slaves could be legally killed, tortured and raped (even children). Serfs might not have fair access to the law but at least in theory they had recourse and society recognised mistreating them was immoral.

Serfs could (meaningfully) marry. They were tied to the land so could not be separated from their families and sold elsewhere.
You are purposely ignoring the point I am making - the suffering WILL NOT end if the war ends. It will become much worse in fact. The only outcome of the aid stopping is the complete conquest of the country, one has to be completely blind or a shill to trust any treaty at this point.

I think the current anemic levels of support are insufficient, and the restrictions imposed on Ukraine in the name of "escalation management" are outright criminal, but even this level support is better than nothing. We are talking about war of extermination here.
How have you been working on it? Asking for a friend ;)
`--offline` :)
Can confirm, I've done quite a lot of walking and properly marked trails are generally very well kept. I've walked quite a lot of the Cornwall coastline and there are active efforts to improve the walkability in certain areas in response to storms and such like. But yeah, you're very unlikely to find any kind of cycling infrastructure outside of cities, and even then its not amazing
