The logic is straight-forward. Whether it is necessary, correct, or advantageous, depends largely on your circumstances and personal put look.

A) historically a number of groups have been disadvantaged.

B) this has lead to those groups "falling behind" advantaged groups from a wealth perspective.
[side bar - wealth begets wealth, while poverty begets poverty, and while it is possible to rise up it is hard]

C) since it is easier to get good grades when you have money, it's more impressive to get good, but not necessarily top, grades from a different starting point. Thus the route, not just the result, should be considered when reviewing applications.

D) thus admitence with "just grade scores" tends to favor those groups with money, which would result in a largely hermogenous student body.

E) education extends beyond just knowledge. The goal is to turn out adults who will function well in a society as a whole, get good jobs, add value to the community, and do on.

F) in modern times it is considered poor form, or worse, to exhibit bad speech or behavior patterns. You can no longer behave like your great-grandfather, you can no longer speak like your grandfather. To do so will harm your prospects.

G) thus, in order to become better human beings, its good to rub shoulders with those of different social, financial, gender, ability levels. In the safety of a school environment everyone can better be taught, and practice, the social norms of the day.

H) thus a diverse student body is good for all students. Previously disadvantaged groups get a leg up. Currently advantaged groups get to interact with those dissimilar to themselves, and thus improve those interaction skills.

US society likes to believe that "hard work" is the secret to financial position. But hard work itself is hard to measure, so we measure grades instead. However grades are more a function of current economic status, not work, and if anything reflect the hard work of the parents, not the students. There are various tools used to try and improve the proxy measure, things like diversity quotas and so on.

Of course imperfect improvements to imperfect proxies still result in contraversy since the system is still flawed. And naturally those most disadvantaged by the rules feel the sting the most.

None of this explains or excuses the behaviour of the school in with-holding these results though. The logic behind that is strange. Why would a top quality school, with a diverse student body, look to prejudice the ability of those students to get good college positions?

I can see some logic in not making a public song and dance about it, but surely all students, and their parents, should be notified as soon as possible?

On the up side, the fact this is "news" at all suggests this is a very uncommon practice.
This article concerns the metrics we use to decide how to advance kids into advanced educational opportunities. How is that a “trite matter of near zero import?”

I think your view of the conservative reaction may be colored by the fact that you don’t have the other side of this culture war wherever you are in Europe or Asia. To my knowledge, elite high schools in Germany or China aren’t abandoning objective metrics like grades and test scores on the theory that those things are “racist.” Heck, Germany and France don’t even track outcomes by race the way Americans do obsessively.

Anybody who generates wealth via business ownership is different from most of us - business risk should have at least a chance of reward, otherwise why take the risk? Of course rent-seeking, regulation-gaming & parasitical industries such as finance and real estate muddy the waters, but fundamentally the existence of some number of ultra-rich individuals is a natural outcome of the opportunity to generate wealth via business.
Huh, this is a totally legit reason, but the solution is so horrible it shouldn't justify it. Yet I cannot come up with a "proper" way to handle this. Is there any?

I quit the tech industry, but don't know what to do next
I worked very hard as a software engineer and ended up working at a very well known tech company, they also paid extremely well. But after a while the feeling of excitement and love I had for this field changed into disgust, anger, and stress. Looking at my options I made the difficult decision to quit, and it's now been almost a year now that I haven't worked. A great year of leisure, sure, but I attempted to figure out what to direct my life towards and failed.
Nothing came out of it. I don't enjoy tech anymore, nor do I particularly enjoy any other fields of work. I had the good fortune (and good financial management) to make some investments with my savings so I'm probably able to live without working for 10 or 15 years. But I don't want to be aimless for that entire time. I have some hobbies but they're not practical to make a living out of.

Some people here may have dealt with these feelings. How do I find a new purpose?

While I agree with the principles of what you're saying, the facts are a bit off here: the instance timeline isn't the default, and the lead dev has tried to nerf it a lot in many ways – I think it doesn't even show up in the official iOS app? Also, anything posted "to the instance timeline" also shows up in federated timelines if you follow the poster, unless you're running a fork allowing "local-only" posting.

One can always drop by https://mastovue.glitch.me every so often to tour the local TLs of instances in the neighborhood (https://www.comeetie.fr/galerie/mapstodon/) to see if there's anyone worth following.

I've never heard of a good argument for this as compared to a capacity, length, and data struct.

The argument doesn’t stand on the merits.

They begin their article with the thesis that the school is “withholding awards” from Asian families.

When you read what actually happened, the school gave certificates to all student in mid November.

One parent is mad because the school didn’t separately notify the parent separately, and they didn’t do it “fast enough” so their kid could list it on an early college admission.

On its merits, the argument falls apart under analysis of the data.
Ask HN: Experience with “Arduino Pro” Platform for Professional Use?
Arduino PRO: https://www.arduino.cc/pro/

This is a complete HW & SW platform for IoT/IIoT/whathaveyou end-to-end applications. Professionally designed HW with Cloud/ML SW support. It seems that they will work with you to develop custom solutions or you could enter into a partnership with them to deploy these solutions to your customers i.e. what they call "System Integrators".

Question is: Has anybody here used it in a professional capacity and could you share the pros & cons?
Nice!! Debugging definitely doesn't get enough love! Especially not on HN.

I already have a diversified stock portfolio, so I'm happy keeping my RSUs as a leveraged bet on my employer. I got one piece of advice recently, which was to sell enough of the vest to cover the tax that it will incur - since RSU tax is incurred at the point of vest in my tax jurisdiction. YMMV on that depending on where in the world you are.

Just equip it with a paper tape, give it the current cell and state as input and use the output to decide whether to move the tape or write to it. I'm sure you could encode a universal TM in a handcrafted neural net this way.

Maybe it's cheating, but after all, this is the only way humans can do universal computation- we can't hold an infinite tape in our head either, and neither can a CPU, we have to give it sufficient scratch space to act as the tape.

Alternatively, perhaps there's a (very large) neural net that can prove things about Turing machines that aren't too large. It only has finite input and finite output (it's not Turing complete) but it can prove stuff about smallish Turing machines, providing the proofs aren't too long. That seems reasonable, because that's what humans do when we prove stuff about Turing machines! Perhaps neural nets could never actually do this, either they're fundamentally not capable or we never work out how to actually find one that does, but it seems possible?

Note how they have mis-appropriated the usual meaning of the word "fast" as it relates to software. "Fast" in a software context means fast for the user, at runtime. Here they are referring to the development speed.

My neighborhood was built in the 1960s, not with cul-de-sacs, but curvy streets and no direct routes through. Still, there's a network of shortcuts, paved like sidewalks, that radiate out from the school.
prosecutors will accept a much smaller sentence

Not sure what you mean there. The prosecution recommends a sentence to the judge. They are agreeing to recommend a shorter sentence than they would have if she fought.

Judges (especially federal) are despots and don’t care at all about prosecutors or what prosecutors want. The judge will want to know exactly how much she blew on bad investments, how much she stole for herself, and how useful her cooperation has been. Then, using the sentencing guidelines and the United States Probation and Pretrial Services Office Presentencing report, the judge will impose a sentence.

> But how is it better to sit at home making $0 than working and having an income?

I had that very discussion with a co-worker leaving. They told me working wasn't worth their time, and they'd better care for their home, family, themselves etc. instead.

And it wasn't that they were rich or their partner had a high paying job, more that the cost of daycare, private teacher, eating outside every day, work related stuff (clothes, commuting etc.) and their general health and mental impact made it a net negative for them. Working a job they didn't enjoy just didn't make any sense.

The interesting part to me is that the calculus didn't change overnight, it's more because one day they stopped for a while and thought long and hard about their life, and came to that conclusion that was there for a very long time already.

I don’t need to know how my 50 year old plumbing works

You should if you're going to fix anything or make any changes to your house. It isn't that complicated and it won't be very different from what would be in new construction.

Because the likelihood of an underlying system having a problem is slim to none.

If you put the wrong things down your drain, it will clog. It would be better to understand your plumbing before breaking it.

It’s no longer good enough to make a memory efficient app

For JS devs, I’ve found it’s actually best to isolate your exception handling from exceptional logic. As in, this will perform worse called in a hot loop:

function fallible(a) {
try {
return anything(a)
} catch {
const b = somethingElse(a)

return anotherThing(b)
}
}

… than if your somethingElse case handles anotherThing, or if you do more work in the try block. In some cases exception throwing outperforms if conditions as long as both the try and catch blocks only do one thing each.

Anecdata…I took a new job for a decent raise at the beginning of the year. The inflation this year ate up 1/3-1/2 of the raise.

I quit a month ago as the money wasn’t enough for me to move forward in life (VHCOL area), management was all older and I felt they do not want to adjust to 21st century processes, and I wasn’t getting any opportunities to really grow.

I have not applied anywhere yet, I’ve taken a couple trips, been spending time outside, and doing a lot of thinking and a little studying/research.

I have no debt, a decent savings, but not enough for a mortgage or to have kids. Employers don’t have a lot of leverage over me because I’ve never made enough to buy-into those adult things that keep your finances constrained.

I can not work for the next two years pretty easily, although I doubt it will last more than another month or four.

I’m not in FAANG and find most companies don’t have much to offer me compensation wise (in terms of letting me grow in my personal life). Not interested in wasting my life working for all these things in the middle.

If you can’t have what you want in life, that’s acceptable. But why get on that career treadmill for a bunch of stuff that won’t make you happy ?
David Chalmers – Does Consciousness Defeat Materialism?
If the atmosphere around crypto makes it easy to scam lots of people out of lots of money (which it does), then I think it's absolutely fair to make this story about crypto, if only so that otherwise-naive people who hear the news will think twice before investing in the next big scam.

It's not necessarily that the technology inherently lends itself to scams, but the culture around it absolutely does. A startlingly large percentage of the biggest players in crypto have turned out to be scams, this isn't a one-off thing.
Not for the crypto though. For ripping off the investors.

My dad told me a story about some British pilots who were pitching in to help the Soviet air force during WW2. The day the temperature dropped below freezing, the women brought out big kettles full of fat to feed the pilots. The RAF pilots were disgusted. But after flying at altitude in the cold, they relished eating the fat. It was loaded with calories that kept them warm.

I noticed something similar when I'd go skiing. Loading up with eggs and butter for breakfast meant I'd never feel cold.
This line in particular made me do a double-take:

> with most TJ students in a protected class of “gifted” students, most of them racial minorities, many with disabilities, and most coming from immigrant families whose parents speak English as a second language.

That is, at best, incredibly misleading, if not outright wrong. The "racial minority" here is Asian, which makes up ~70% of the school population (whereas the school district as a whole is 30% Asian; the population of blacks and Latino are collectively ~4%, whereas the school district is 30%). This aren't disadvantaged poor families--at least some of the Asians come from families specifically moving to the high-cost-of-living area to try to place their kids at TJ, and I suspect a household income of $200k would put you in the bottom socioeconomic half at TJ. Note that none of the students are in ESL classes, and only ~2% are on reduced-price lunches, whereas the school district as a whole skews more like 20% and I think 30% for the latter.

So, in short, the student body at TJ largely isn't comprised of poor people who need every leg up they can get; it's comprised largely of people at the top of the socioeconomic ladder who are already walking on water.

(Disclosure: I did in fact attend this school.)
