Seems like 90%+ of tech companies religiously lose money, or maybe its just the 12 that I've worked for in my career? I remember a time when losing a billion/year would result in massive layoffs. Most don't even blink at a mention of a billion lost in a year as far as I can see.

Any thoughts on rebasing Brave to Rust, or else picking up the now-defunct Servo project?
That's really interesting!

Of course, if the native population died off around them, the Vikings would probably have expanded their settlements and perhaps ruled North America instead.
Piggybacking on here to +1 the request for perspective.

I'm sure you can share some interesting stories and/or arcs of what-was-envisioned vs. what-ended-up-happening.
A founder with the choice of taking YC money also is free to make the decision not to take YC money. What's the problem besides some abstract argument of moral superiority?
In particular we can imagine it might look more similar to how China, India, Africa, etc. turned out, with subjugated local populations serving under foreign imperial governors. The eventual collapse of the empire might then result in most of the Americas being populated by ethnically Native American states.
I got the impression developers shunned Amazon app store because it's a bad experience for them. Quite often am I seeing apps there that are many versions behind the play store.
You have plenty of choice. Your choice might have consequences but you still have the choice. Most users are fully aware of how tracked the free internet is.
Agreed, "gifted" implies a static frame, which is anathema to learning. Alternatively, "accelerated", implying the student must work to keep up the pace.
I do think about that idea as well, but population density (on both sides) is an important factor though. Both the Vikings and the native populations had far lower population densities than, say, 15-century Spain and Italy, which is likely why the diseases didn't spread in the first place.

Mesoamerica a few centuries later did end up having the density required for disease transfer as history shows, but it was also helped along by the Spanish's active invasion. If the Spanish hadn't ever set foot on shore and the Mesoamerican society was allowed to develop, they would likely have developed their own diseases and the subsequent immune response, which may have helped fight Smallpox. But the Spanish got there before they had that opportunity.

If the Spanish invasion had been replaced by a smaller troupe of Viking traders, I would be interested to see what would happen, and you might be right if you only change that one variable. But who knows?

My personal anecdote on my schoolboard's gifted program:

Even though teacher after teacher had nominated me for the program no one actually gave me the placement test until 7th grade. Some math, lots of puzzles, timed quizzes, etc. I passed and spoke with the teacher. We didn't get along, and in today's slang she would be considered a 'Karen'.

I was the only person of color in the program, in a majority-minority school. And with the gifted teacher not wanting me there I asked to be taken out, went back to my 'ghetto ass friends'. I took the classes I liked and never gave the G&T program another thought.

I went on to take regular accelerated maths, language, history with a sprinkling of AP, dual credit classes. Where I met up with all those supposedly gifted students again.

Based on my experience on schooling in the 90s. The G&T programs have a serious racial issue that is only now being reckoned with.
Yeah, but since there are domains where C++ is unavoidable, this is the best we can do.

Was this generally the case for the native populations of the Americas? I'd actually be very interested in some works on native american supply line( problem)s.
Ok, I'll bite.

I find these questions a bit strange, because it sort of misses the point of learning as a whole. Do I use Civil War history every day? No, probably not, but I also don't regret being taught it at school. Am I conducting a lot of chemical experiments? No, but I think it's valid for me to have learned chemistry in high school. Am I performing literary analysis on everything I consume? Well, yes, but that's just something I do for fun, it's not like people are paying me for it.

The reason that they teach calculus is two fold. First, most of this stuff is somewhat additive. Do you use "calculus" every day? Probably not, but having learned calculus might make other aspects of math or programming easier, stuff that you might end up using full time.

Second, the people designing programs for Computer Science degrees (and probably others as well) at some level need to have a "one size fits all" for their students. My professor doesn't know if I'm going to get a job doing video game physics, if I'm going to designing video compression filters, or if I'm going to be a web developer, but they want to make sure that if I graduate with a CS degree, I am more or less qualified for most reasonable software engineering positions, or least given the tools to become qualified.

We could extrapolate this logic further: how many people here are realistically writing low-level C code? I know I'm not, but I don't regret them teaching me how it's done, it informs my high-level code writing.
Do you actually think VC money is predatory?

I have a $1m MMR startup that I founded without any external funding - but mostly because I was naive to such structures existing at all. I would have saved years of struggling if I had an initial cash infusion of a few hundred thousand.

docker is a second-class citizen on anything but linux.
i'm especially amazed you bothered with the m1 mac mini if you wanted to use docker, considering how little memory it has. the memory overhead of having a VM running with only 8GB available is significant.

yes, i know the docker on mac has "native" support for the m1 cpu, that doesn't mean its not running a VM.
Is it the resolution you've found limiting on the M1 Air? My eyesight is slowly getting worse so I'm assuming I'll have to run both at 200%. Which makes the Air a 1280x800 screen - something I last had on my 2009 13" MBP!

So, you had a teacher spend one-on-one time with you. That's the whole point of what I'm getting at. That's what EVERY kid needs.

Because far, far too many web apps need to display user-entered data, and it needs to be sanitized. When markdown is converted to HTML, as it is on this form, it still should be sanitized afterwards to deal with any vulnerabilities that were discovered after the user entered the data, even years later.

Leaving aside the whole "please don't fulminate" thing, you're going to have to be specific about which part is incorrect. Is it just the "he wasn't originally involved in Firefox when it started" word choice and you'd like that amended to "he didn't start Firefox (though was aware of it and soon incorporated it into Mozilla's strategic plans)"?

The righteous demand for truth would be a bit more inspiring if you'd similarly correct the GP for "lying" about you being the one true Mozillian, though.

But... what the OP writes are strong conventions, no?

Coming from Spring or Java EE:

> implementations that could literally be a lambda function (on receive message, write row into DB) are a festival of multiple tiers of objects, mappers, mediators, IoC frameworks, wrappers, Nuget packages, etc., etc.

Spring or Java EE is a strong convention, so IOC is one automatically as well (both make use of that heavily). Hibernate would be the next strong convention, therefore mappers are, therefore we will have multiple tiers of objects. Wrappers will also be needed in a language like Java. About the rest of this list I can't say much now, but I would argue that lots of what this person is doing is based on strong conventions in the enterprise world. And it goes on:

> Everything is in multiple projects. Simple constants (like: API routes - '/api/foo/bar') are indirected into files containing those strings, so there's a huge cognitive overhead and much clicking around to make sense of it. God help you if you don't use an IDE.

Coming from Java again, everything won't be in multiple projects, but in multiple Maven modules instead. AFAIK that is good practice, or, if you want: a strong convention. Stuff like API routes will indeed not be saved in a code file, but in an openapi file instead.

IMO then, what this person was doing was actually following strong conventions. Yes, these are often also specific patterns, but what is the difference, specifically for these things listed here?

It seems to me much more that the person was probably "limited" more by the language. I think there are fairly good reasons for all of these, especially when working with more than ten people - in a language like Java. And in this case you will have to use Java (or something similarly famous) because otherwise you won't find a replacement very quickly that is fairly cheap. Now, maybe the person would not have needed all this in such a small project that is just for one person. But who knows, maybe the project grows. Or maybe this person was simply familiar with this and could get this down fastest. All in all, I think there are many good reasons to decide to make a project with patterns/conventions like this.

Again and again it's interesting to see the US step up when faced with these world wide challenges.

> nonsense puritanical values of big tech

I don't think it's "big tech" that has these issues. Pornhub is big tech too...

The problem is that you have you walk on egg shells for anything that could come even remotely close to children, and really a lot of the American (even though they may like to think otherwise) a not-insignificant portion of the European market will give absolutely credence to anything that doesn't explicitly ban sexual things.

Look at what happened to OnlyFans. That wasn't big tech, that was the financial institutions, and the same group that did that is targeting Pornhub next.
I said "4 letter". You are confusing it with another unrelated word.

You clearly did not read the rest of my comment other than the first line which you also read incorrectly. And I didn't mention a single anecdotal thing in my comment so not sure what that's all about. So it seems like you are commenting for a specific agenda.
If you do the forestry right you create many plots in there and aim to cut down e.g. 2% in a given year. That mean you will get the whole forest replaced in 50 years. If you're careful to not cut too much in a single space then the animals and plants can move around and it should be ok for biodiversity.

Now for the energetic biomass - this is more like 5-10 year rotation so while the animals can move around the plants can't. Those will be mono-cultures to sustain energy demand until we have enough of some other energy sources.
Toronto has a dozen highly ranked private schools and few dozen others. Tuition is usually less than $35K CAN a year.

Most cities have several private schools. You usually don't need to move you home to move your children to a new school.

We would have seriously considered private school for our gifted children if the public school hadn't offered it.

So imagine how you turn off entire households and then bring them online in one sweep as soon as "reliable power" comes on. How do you propose to handle that?

> So. How it is... I know about blinking E-21 because I had to walk into the cellar to read the meter and email the counter value to my utility a few days ago.

So:

- a smart meter that cannot upload something to a remote FTP server

- and a system that's supposed to turn off "cheapskates" if there isn't "reliable power"

Ah, this will work just wonderfully, and reliably.

> Or maybe https://en.wikipedia.org/wiki/Blackout_(Elsberg_novel)

Ah yes, disaster thrillers are the source of knowledge and truth we should turn to. Because, as you put it, "it's telling as it is"?

> Yes I'm very wary about cyberphysical systems implemented by the lowest bidder, and operated by outsourced nobodies.

And yet, "With smart meters. Premium payer gets power. Cheapskate gets switched off.".

This will work wonderfully.

Yes. But again, not a lot of options to avoid it as you said.
You also had facebook pumping resources into PHP with HPHPc, HHVM, trying to compile a spec, etc.

That definitely would have helped keep PHP alive through the period between PHP 5 and PHP 7.

Additionally, PHP's releases of 5.3, 5.4, and 5.5 introduced enough new functionality that the bump was more than incremental. It had backwards-breaking changes, which should have warranted a new major release if PHP followed semver.
Modern cartoons and movies are now really fast paced. We've adapted to them that it makes watching the older stuff painful. YouTube and game videos take this to an extreme. So that is probably evidence of an attentional feedback loop.

You know what is absurd? How about the idea that you should segment children at a young age, before they are anywhere close to fully developed mentally, emotionally, or physically, and publicly label some as "gifted" and some as "normal". What could possibly go wrong?

Dumbest fucking idea ever.
So, if I understand correctly, your argument is that this specific job is a really, really bad match for some specific people (and more specifically for their physical and mental health), right?

If that's your argument, I'm pretty sure that I can find a few other jobs that are really, really bad matches for the physical and mental health of some people.

Now, I'm sure that I can find other arguments that go in your sense. If I had a daughter, I would probably not want her to become a sex worker, because I would be scared for her physical and mental health, in addition to the potential of ostracism. No idea how I would react about a son becoming a sex worker. But then, I would also not want my child to become a soldier or a cop for most of the same reasons, or a trucker or a miner, because I imagine that both jobs are also bad for physical and mental health, or any office job that would put them under the orders of an abusive boss, or a nurse in an underfunded hospital, or an Amazon warehouse worker, etc.

So, what I'm attempting to say is:

- we agree that it's very likely that low-end sex work is most likely a really bad place to be;

- we probably agree that there are lots of really bad jobs in the world;

- there are stigmata to sex work, including social pressure and the fact that low-end sex workers are basically not protected by the law;

- seen from a comfortable distance, and with the additional luxury of not being in a shitty job (anymore), my impression is that the biggest problem of sex work is not the sex but the stigmata and that these are pretty much artificial.
I think you're reading a position in my comment that I'm not taking. I'm not somehow implying that if you open the conversation to wider perspectives that you'll find broad support for eliminating gifted programs. On the contrary, as someone from a poor school district (that also barely had an IEP program btw, most IEP students were bused elsewhere if they bothered to even stay in school), I have fairly mixed feelings on the whole thing.

What I mean to say is: when talking about education policy, think about aggregate outcomes. Not just the outcomes for yourself, your friends, or your cohort. You went to school and your general contractor went to school. Both of you should succeed.

You've never bought batteries? Or, did you think that light weight and small yet powerful batteries were somehow inexpensive?

Whenever there's a discussion of using batteries for anything, the three issues that come up are cost, weight, and size. You can take a hit on one or two to get some improvement on the remainder, but...

Batteries for portable equipment must be good on weight and size given the power required, so cost is what goes up.
I don't know much about Native American war theory.

But I know that Medieval English Longbowmen were only given something like 6 arrows per battle. And even that was enough to stretch the capacities of Medieval Britain's supply chain. 10,000 Longbowmen x 6 arrows is 60,000 arrows per battle.

IIRC, it was said that during wars, there wasn't any gooses or ducks to be found in all of Britain. They've all been killed, and their feathers plucked for the war arrows.
Think out of the box for a second, is this really the only possible choices we have here? Or are billionaires using and designing the system to create more opportunities to make $$$ at the expense of others work.
To be fair, that has pretty much the same result as "magically we're all billionaires" - when you find it's going to cost you 120k for a burger, as the billionaires need more money to get them out of bed and into the McDonalds kitchen.

The nasty-but-necessary aspect of capitalism is that you need a few rich people at the top and many more beneath agreeing to those rules that put them there on the offchance they'll make it up to those lofty heights themselves.
Timescale engineer here

The initial drive for this was some of the work we did on Promscale, along with some observations I made when experimenting with potential optimizations for compression. We saw that a bunch of workloads involved exporting datasets to external tools such as Prometheus and pandas, which would materialize them in memory, and performing analyses there. Furthermore, the queries in the external tool would often be more readable than the equivalent SQL. I'd also observed earlier, while experimenting with decompression optimizations, that, as long as it was small enough, materializing the dataset this way could be surprisingly efficient. This, along with some dissatisfaction in the difficulty of writing certain kinds of queries eventually led to this experiment.

> Is this meant to be a "short-cut" to express complicated SQL queries, or is this meant to adding new semantics beyond SQL?

This is a surprisingly difficult question to answer; due to Postgres's extensibility, the line around "new semantics" is a bit blurry. I believe that everything we implemented could be desugared into SQL queries, though it's possible it would need some custom functions. However, we don't actually do this yet: right now the pipelines are implemented entirely with custom functions and operators without touching the planner at all. There ended up being a 3-way tradeoff between experimentation speed, execution speed, and generality. While we could theoretically get the best performance on large datasets by by adding a translate pass expanding timevector pipelines into subqueries, this ends up in some difficult and brittle code, which isn't worth implementing at this stage in the experiment. In addition, it doesn't necessarily result in the best code for smaller datasets or less general workloads since there are overheads to its generality. Since our hypothesis right now is that there's a demand for tools to work with smaller datasets, we started out with the simpler implementation.
