> What really happened is that some people on Reddit bought up a bunch of GameStop stock and went around convincing other people to buy it by telling them an appealing but false story. If done deliberately, that's called a pump-and-dump.

Disclaimer: only read around figure 6 and the part you quoted

I'm willing to buy this as part of the explanation, but reading through the methodology for Figure 6 seems flawed. It doesn't appear to account for positions being managed through derivatives (possible reporting requirements are different here?) as firms might have delta-hedged through these means rather than simply buying spot. Really weird that ctrl+F hedges gets so few results, and the Consolidated Audit Trail sample only beginning on December 24, 2020 seems like a major flaw. Like, really, there's a once-in-a-generation market event and the SEC only bother to get CAT data from a month (and many holiday+half days) before regarding the major event for a listed security that had been brewing for months?

For me the most interesting (and imo alarming) part of the whole saga was the coordinated action by Robinhood, Trading212, IBKR and others to turn Gamestop into a sell-only asset. Increasing margin requirements? This seems obviously responsible in the circumstances. But effectively pausing a stock while there is no official trading halt was insane and seemed on the face of it to be coordinated. It's obvious that a retail-heavy stock would tank from such action being taken. If you did it to TSLA or MSFT there would be panic and dumping too.

(After watching the video where he addresses this I'm still not super convinced there weren't alternative ways to do this without having outsized impact on specific stocks. He definitely plays down the fact that the 28th close was like -50% relative to 27th close as a direct consequence of the volatility caused by the pause, and doesn't mention that those with cleared funds still couldn't buy the stock with these brokers)

Also interesting is how hedge funds have learned to exploit this kind of frenzy. I really hope that it will be possible to do research on BBBY to find out how much of that was astroturfed. Whipping up irrational actors through astroturfing seems like a pretty smart thing to do if you're in in Hudson Bay Capital's position with the agreement they had with BBBY. I'm not accusing Hudson Bay Capital of anything, I'm simply pointing out that the incentives were there. I've not watched the entire video yet, but I really hope it delves into that. The BBBY subreddit was kind of a morbid curiosity for me.
This is the flaw in having an entirely hateful view of splitting, that view is itself an example of splitting. You have to instead believe that there is a time where it is appropriate and useful to split (e.g, war) and times where it isn’t (general thinking)
How much of "conditioned not to want them" is from overly effective anti-teen pregnancy campaigns? Scare the kids straight that children are a one-way trip to the poorhouse so they keep it in their pants at prom. A decade later, some of them who easily could afford a family choose not to raise one because the lesson stuck.
Technically CEOs are also working class, since they mostly live off of their salary. A lot of this is voluntary, since with a bit less spending I'd imagine most BigCo CEOs could easily cope on capital income from the investments their salaries have afforded them. I wonder how that affects their classification...
That shift is what lost me.

Admittedly I was at a shop that wasn't likely to shift to an enterprise version so not a direct economic loss on their part but definitely stopped thinking of it as a solution to consider.

Because the fatal flaw of a lot of advanced societies is elevating individualism. You are ultimately just a part of the human species and we evolved naturally to produce babies and raise them (i.e. desire for sex). We were also a lot more tribal and it was easier to raise kids with a village.

Combination of the latest trends of the past few decades (contraception, individualism, nuclear families) goes against the natural design for the sustenance of our species. Nature doesn't have morals and is pretty ruthless, so if a sub-species doesn't want to have kids, it will cease to exist and will be replaced by the one who values kids.

South Korea will be an interesting example to watch - whether they reverse their course and start valuing kids as a society, or they might get replaced by immigrants or are taken over by the neighboring countries. Nothing good or bad inherently with either option because life is meaningless anyway.
Noob here, but aren’t the best tires made from natural rubber? Or am I mistaken?
I'm sure I'll get downvoted for this one, but can we stop using the word engineer in the commercial software and startup sector entirely. It's mostly hacking, fucked up things that make you cry, turds smeared all over stuff, religious factions fighting over faith (marketing) arguments and embarrassing catwalk fashion show bullshit. None of that is engineering.

I'm only here because for some insane fucked up reason, the money is at least 4x better than electrical engineering was and I really like lots of money and will quite happily sell my soul to the machine above for it.
So who are the wealthy in Brazil? If software developers are making peanuts, what is the road to financial success? I hope it's not just inherited money.
The problem with this simplification is that it ignores risk. Being an employee means you get paid, and can change job it the business fails. Bring an owner/investor means you might lose all your money if the business fails. That is massive risk, and entirely ignored by the above characterisation.

The issue is that InfluxDB is an infrastructure product. Changing the core impacts the way users interact with the product. If Figma decided to change their backend, it could be transparent to users.

Opinions could be different if first they implemented a complete compatibility layer, Flux included, prior to making the migration.

In my twenty years in the field, I’ve never met a packer. Every engineer I’ve worked with, from college hires onward, is constantly building a map of the world in their head and I see it in their code. The problem is either that they don’t realize what lands exist beyond their map, or they recognize that there have to be edges of their map to be able to be an expert in something.

For 21 minutes and 53 seconds, I highly recommend this video. It gives so much context and describes the situation in as neutral of a tone as it's possible with a sprinkle of dry humor. Also, Patrick takes it a step further by answering the question if something like this could work again as well as discuss how this system that emerged compares to modern day cryptocurrency systems.
I remember watching Formula 1 in the 80's. The amount of 'marbles' from tyre degradation was amazingly high. If you have seen a race with a dry line after rain it was that striking.

And yet now, very few marbles, it would seem though that they are a lot smaller.

It's probably suffice to say 39°C. It's unlikely the temperature was exactly 102°F; these measures are almost always rounded to the whole unit.
There's so just room for some sort of splitting to represent truth.

The article talks about packers and mappers and that either is it isn't a useful distinction. I am open to either, but I wouldn't dismiss the idea because it's "splitting" by nature.
I think this is common in companies with a lower salary range, no stock options, bonuses etc.

This is particularly apparent in large cities, where salaries can be almost double at each end of the spectrum. From what I have seen promotion to senior or hiring inexperienced staff at senior level is the only way these companies can retain or recruit staff.
I've had it happen a few times, and on a few different bikes. Usually the cause is a chain that is too loose, and especially if the wheel is cocked to the left due to the drive side of the wheel being pulled forward from hard pedaling.

One chain tensioner on the drive side is a good preventative measure, I prefer both sides since it makes things easy.
Exactly, guess I would be able to land a job as an algo trader. Maybe would even be able to create my own shop.

But the thing is, I just would like to do something else. Trading is not that exciting anymore. It was a tough battle for the last years, resulting in incremental improvemts to speed, strategy and infrastructure. Now kind of ready for something new. Also would love to learn something new as well.

Sure could provide my tax statements, as a proof. Just think it is weird to do so. Also the numbers are kind of high - so would rather let it be private.
I don’t really get the first example.

> Why do we need variables?

These aren’t questions that a junior engineer couldn’t answer. These are questions that somebody who has passed a single programming class ought to be able to answer.

Then they have questions about this vite platform, which I’ve never heard of, but it seems like they are asking “does software have dependencies?”

It makes me a little suspicious of the article. It looks they’ve set up a contrast: packers vs mappers, where packers are the bad result to end up aligned with (then, if you want to be a mapper, come join me!). But it seems like an over-shoot. The questions they have the packers failing seem to indicate some wild levels of incompetence.

Sorta like those online IQ tests that always tell you that you are a genius.
I keep seeing this (anecdotally) out if the Midwest. Folks with 4 years experience doing mostly front end work who’ve never deployed anything with the title “staff engineer”.

I sort of feel bad for them because without a large step down in title they’d never get another job. Perhaps that’s the trick - title inflation to mask bad pay?

> 44100khz, 16-bit audio can perfectly reproduce audio as far as we can physically tell.

I agree on the kHz (as well as on MP3), but I deeply disagree on 16 bits.

Because yes, if you keep your headphone volume at a single reference level and never turn it up, then 16 bits is fine. This is very much proven.

BUT this ignores the fact that people often turn up the volume a ton to hear the quiet part of the classical music, or on that YouTube video where the volume is inexplicably 5% as loud as it should be.

So in practice, 24-bit audio allows you to retain perfect fidelity even when you have to turn the volume up. 16-bit doesn't.

I don't understand why nobody ever talks about this. (Or why you have to install special utilities on your Mac to be able to turn up the volume to 200% or 400% in order to listen to those YouTube videos that are maddeningly recorded at 5% volume.)

It genuinely pleases me that they are sticking their heads in the sand. It actually brought half a smile to my face.

I hope they continue being this confused about what is happening and where the world is going.

Probably true about Excel (or at least non-cloud Excel), but not JS.

You can apply the App Store model but for websites. Require ID to get a TLS certificate, block anything which doesn't do TLS, allow certified websites to execute arbitrary code with a few technical restrictions. If somebody violates the law and is discovered, through either manual or automated means, they can be blocked via TLS revocation lists.

I think they missed one thing: Nobody wants to get locked in with the runner-up.

If they on top of that provided some compatibility layer for Prometheus/PromQL, like few other competitors did, then the prospective enterprise client have warm fuzzies that if they don't like it they don't need to rewrite entirety of their stack to work with something else. People could also use the existing ecosystem and "just plug it in", even replacing Prometheus instances they might have.

In the end people want to ingest the metrics and display it in Grafana. They don't need another visualisation solution that has less support and documentation. They don't want to learn new weird query language that is simulatenously more verbose and less readable than PromQL or even influxQL from v1.

Good luck aligning perfect crystals on a microscopic scale like that.

I was thinking maybe a bulk crystal could be a layer in ICs.
I can definitely say that I am a mapper and not a packer. But I can also say that I am pretty much _all_ mapper and no packer. This means that it takes me forever to understand a lot of things that presumed packers (or more balanced individuals) would get in a jiffy. This is not intended as a humble brag! For the longest time on some projects I just don't f**ing get it, I start to feel dumb and in way: out of place. The imposter syndrome makes itself heard. It's genuinely uncomfortable.

But then I start to get it and finally do get it. The packers are now "experts" at their acquired knowledge and seem to have a hard time changing opinion where they should.

Back in school I had real problems getting good enough in subjects that required learning pieces of fact that don't quite go together or display some inherent system. My friends didn't. Things that have a system or are "logical" in the wider sense, easy peasy.

EDIT: I would call myself a decently accomplished programmer and engineer at this point after 25 years or so working with it.

Twitter has recently started showing a kind of "fact check" on some posts that explain why it may be misleading... I've seen one of these even on an Elon's post! These are apparently added by the "community"... it seems really helpful so far!! So, I think at least this initiative is helping a lot to contain misinformation.
So in other words you don’t eat that yourself and prefer to eat either high end quality food (that’s unlikely to have questionable ingredients and tastes good) or bake at home? Seems we are not so different after all.

So why defend the ingredients intended to make bread last longer and appear fresher than it really is?

Appalachia is much cheaper than SF, so one can make less and still have a good time raising their kids. It's not about absolute income, it's about purchasing power parity between areas of a country or world.
Someone expressed this very well to me.

Top tier companies pick up the faang rejects.
Middle tier get the top tier rejects.
Bottom tier get the rejects from the middle tier.

“We get what’s left. Sometimes we get lucky and get someone who’s fallen through the cracks”

Personally I’m not a massive fan of the faang recruitment techniques and I think there’s a lot of fantastic senior engineers who want to do interesting work without jumping through ridiculous hoops. The main issue is usually just being able to pay sufficiently well to attract them in the first place. It’s a tough argument with the exec team to get a salary through that can sometimes be double or triple the companies median.
It had, and to this very second continues to have, world-class dev-tools. Which is doubly ironic because I believe that the dev-tools are an independent open source repo from Chromium itself but what I can't say with certainty is how many hooks are required into Chromium itself that would prevent adoption by Firefox

I can't recall so much from the early days but modern Chromium releases are packed with "shiny new toys" that the web-dev crews love. I deeeeeeeeeply appreciate that saying such a thing further entrenches the "Chromium is eating the world" perspective, but I'm just pointing out that web-devs love shiny toys and Chromium seems to ship them on the regular

So, too, do they ship an unholy number of C++ footguns, but omelet-breaking-eggs-etc-etc :-/
It's interesting that this mechanism doesn't show up in biology, I can imagine a bug with superpowered bug jump that uses methane the bug produces in its gut with helper bacteria. I suppose at very small scales flight is probably way cheaper, biologically.

It's a theoretical paper. We don't have a good theory about high temperature superconductivity, so they are calculating related properties like "flat bands". [It's not my are, so I'm not sure how good is the relation.]

My guess is that they started this during peak LK-99, and it got published just now, too late for the news wave.

I was very optimistic during the first week, but the evidence so far is not convincing. Unless you work in superconductors, you can probably just ignore this until some experimental evidence appears.
As it shows the observations of positron flux are consistent with well-established physics, I would guess that it is pretty solid.

To be clear, this result does not rule out some form of dark matter as the cause of the phenomena it was posited to explain in the first place.
I keep seeing this take - what do you propose? The implication seems to be that you think we should let humanity die off.

Essentially saying, "nah uh" to that is not a satisfying response and tends to make me believe that our doom is essentially irrefutable at this point. And I say that as someone who tries to look for hope in the current situation. It's hard to find and I've independently come to much the same conclusion that Brain has in this article.

Yes I think v3 is pretty solid, and it's nice that they are still supporting v1 and v2. But I think the "migration" from v1 to v2 was the "painful" part. Not because it was too hard to migrate (I guess you don't even have to, since it's still supported), but because it introduced a very different approach, that was supposed to be the future of influx, that was just basically dropped in the next release. I think some commitment towards v3 might help in that regard. As you said, flux is powerful and took some time to get used to but it's now basically useless if you took the time to get into it.

I like that they are converging towards SQL, but at the same time it's a bit like going back to square one.
They seem more convinced about going full SQL this time though, but yeah

Just searching for this, I stumbled on this documentation page that illustrates the point very well:

https://docs.influxdata.com/influxdb/v1/query_language/

In the same page (about the original influxql in v1), there is a depecration notice for v1 stating that v2 is the stable version, implying that InfluxQL is not recommended. And a pop up notice stating that v2 (flux) is basically deprecated and just in maintenance mode, and that you should use InfluxQL. But as I said in my earlier comment, I guess in some ways that's better than being too rigid and sticking with bad or less ideal technical decisions.
