Bootstrapping Rust entirely from source (2018)
It did not help that CZ triggered a run on the assets at the worst time; otherwise it likely would have been fine. When FTX ran out of money, every depositor instantly became a creditor. I doubt this is unique to FTX. many exchanges may have some shortfall between deposits and credits.

lol large corporations were the least productive places I worked at. Growth came from the sheer inertia of a near monopoly paires with a bull run propped by very low interest rates.

Much to the opposite, large corporations should be weighed down by more strict taxation, to give smaller competitors an edge.

I myself am convinced that man-made global warming can't be stopped without changing the way our political economies work, and I happen to believe that Palestinians are people and therefore deserve basic human rights (which they do not currently have). I'm also a researcher.

I _would_ be thrilled if there was an expedient way to solve climate change. But the best systems models for the earth all tell us that there's one way to solve the issue: just leave the carbon in the ground. That's it. Stop extracting it. Nothing else will solve the problem, it's a really simple, really bad, feedback loop.

This characterization of environmental or Palestinian activists as wanting to have the moral high ground is, imo, a knee jerk reaction. The people on the street aren't in it for clout, they're doing it because it is the right thing and they feel compelled to act. What gets me moving is not wanting to feel morally superior (a religious aspect, more at home in right wing politics), but an anxiety for the future, which is projected to include horrible death and suffering due to obvious problems that we could all fix if we just decided to recognize them.
It is issues like this due to which I gave up on C++. There are so many ways to do something and every way is freaking wrong!

An acceptable solution is given at the end of the article:

> If you use the International Components for Unicode (ICU) library, you can use u_strToUpper and u_strToLower.

Makes you wonder why this isn't part of the C++ standard library itself. Every revision of the C++ standard brings with itself more syntax and more complexity in the language. But as a user of C++ I don't need more syntax and more complexity in the language. But I do need more standard library functions that solves these ordinary real-world programming problems.
Given that neither side has directly attacked the other yet? Almost all of them.

Using nuclear weapons against an opponent who has enough nuclear weapons to retaliate is a "flip over the chess board and stomp on the pieces" move. Presently the US isn't even playing against Russia, at best it's sitting behind Russia's opponent and whispering chess moves into their ear.
you seem to think that he takes his peers achievemenrts as his own. I think that is exactly it. People on youtube gravitate towards people who has that kind of ease and effortlessness to them. Cause effort is just not cool anymore. Pirate just looks so chill and zen and he is quite a clear communicator and knows how to appear smart. And he has actual ins to the industry so he's more interesting than other streamers. The only persona flaw is that he honestly comes across as liking his own voice and has too many 'insights'.
For Rust to fully displace C++, it needs to eventually bootstrap itself, until then, C++ will be around.

Additionally there are no significant new projects being done in Rust for the games industry, AI/ML, HPC, HFT, compiler backends, hardware design,....
> you own a claim on the underlying asset

No, you're describing a secured claim. No crypto exchange I know of voluntarily gives customers a secured claim. At the moment of bankruptcy, unsecured claims are a claim on the company. Not on any asset.

> don't know how more regulated brokers work

The assets are segregated and customer claims prioritised and guaranteed by the SIPC.

> Regulation wouldn't have changed anything here: as FTX simply broke the law

None of what FTX did would have been remotely plausible if they'd been regulated as a broker-dealer. They'd have failed their FINRA audit on day one.

Not saying what they did is impossible at a regulated b-d. It would just take a lot more thought and work than the shitshow they were running [1].

I really like the idea of https://github.com/dinedal/textql, which uses SQL to interact with file-based data stores. However, I don't understand why sq does the opposite—using a new DSL to access a database that already has a widely-adopted and easy-to-use language: good old SQL.
Man I know this. But the simple undeniable fact is - if nuclear was kept on - even less gas and coal would have been used, it's an obvious thing. Renewables did help ditching some of fossil generation, but with nuclear it would have been even more

>the anti-helo drone isn't running a whole sound analysis, just a narrow range

Why? Sure you might be limited to that if you're using an Arduino but with an FPGA or even a cheap "edge AI" NPU you could do a very thorough analysis (even credit card sized image recognition modules with camera are <$50 now). Heck even a seeedstudio respeaker can do live voice identification and isolation, noise cancellation, and 16 direction source location/indication using 4 microphones!
> I find it weird that the convention to use char/short/int/long/long long has persisted so widely to this day.

I don't think this is a reasonable take. Beyond ABI requirements and how developers use int over short, there are indeed requirements where the size of an integer value matters a lot, specially as this has a direct impact on data size and vectorization. To frame your analysis, I would recommend you took a peek at the not-so-recent push for hardware support for IEEE754 half-precision float/float16 types.

Show HN: Boost your warm intros with an AI that finds you the perfect investors
After raising +$4M for my last startup, I've been coding for the last 6 months EasyVC to skip most of the annoying tasks behind fundraising from investors.
1. It takes your startup's description and matches it against several data points of each investor of the database (VCs and Business Angels), such as investment thesis, portfolio companies, investment stage, etc.

2. It gives you all the contact details of the investor, including verified emails and LinkedIn profiles.

3. It suggests the founders of the portfolio companies you should reach out to along with their LinkedIn profiles, in order to get warm intros.

This is for any tech founder raising from pre-seed to series A, of any industry.

Hope you like it, and would love to hear any questions/feedback/comments! :D
Or you could just pay for it. It's expensive but totally worth it (IME, obviously).

> FTX was an exchange, and while the holding company can go bankrupt the customer assets should be always fully funded in segregated accounts

FTX marketed itself as an exchange. That didn't make it one. Giving it money was legally akin to handing any small business in your town money.

> Most of FTX customers were outside US and are not US residents. US Dollars in this context holds no significance.

FTX was a U.S. company. Even the Bahamas outfit had U.S. dollar bank accounts. FTX's customers were obviously subject to U.S. jurisdiction.

> FTX.us was a registered broker

They owned a FINRA-member broker-dealer. Most FTX customers weren't doing business with its b-d.

> with SEC as an exempt broker

Not what Form D means. ("Exempt broker" isn't a thing under U.S. securities law.)

All of them. Exchanges and clearinghouses in a proper financial system are fully collateralised.

According to coinmarketcap and coingecko, there are 200+ exchanges. you're saying all of them are fully collateralized? doubt it.
I think this neatly illustrates why intelligence occurred in humans. Looking at other species we might see that intelligence isn't particularly useful in struggle against environment, it's not greatly important, above certain level neither for predators nor prey. It's more economical to invest in other stuff than abstract intelligence.

But when you have dense populations where individuals pose more threat to each other than other things threaten them with outside pressure of mildly dangerous environment that forces the population into groups despite that you just bound to end up with self referential highly advanced reasoning.

In such environment there is a selective pressure to develop brains capable of modelling other brains in order to survive and keep your offspring alive. But as your brain gets smarter and more capable so do the brains you are trying to model.

This causes tight (rather pathological in the context of living things in general) feedback loop that doesn't develop when predator and prey are of different species.

So it really wasn't diet, or tool use or verticality, or brain facial air cooling. It was mostly just that murderous species bread to the point of being its worst enemy.
Not to be that guy, but if you're going to drop conspiracy theories on HN, you need to cite your sources. Less hand waving and more fact checking.
I think there is a value especially when you are not part of that world. It's like watching a new sport and you can hear the commentators and hear which parts excite them and hear their read on the matter at a higher level than you (I) can. It's a good way to get into the same wavelength. Kinda like oil.

I just liked primeagen from the above. I like him cause he made no pretense to objectivity and he is also very exciteable, which is a valuable information in itself.

As of now, the thermoset epoxy in turbine blades can't be recycled. Turbines optimistically last 20-25 years, which means entire generations of them have either been buried or worse, incinerated.

https://www.texasmonthly.com/news-politics/sweetwater-wind-t...

https://cen.acs.org/environment/recycling/companies-recycle-...

The same is true for solar panels. These are NOT unique problems to renewables, of course, except they tend to produce more waste compared to their energy output than other methods at the moment.

Recycling is a big area of research, but is not yet especially CO2 positive for solar versus just burying them, and non existent for wind.

The point isn't that the problem is impossible, but that these things are overlooked and green washed.
Sorry for my poor English, not my mother tongue...

Well, in debate terms: let's say you could decide to add element to tap water because locally you state "there are not enough of this element", how can you dose it? Some do not drink tap water, will get nearly none, some drink much, some came here for a bit of time coming from other places, ...

Teaching people a good diet it's a thing, "imposing" adding stuff to common goods is a dangerous choice, which could be well abused to do very nasty things.
In your comment above you've suggested two terms that fit better: "Duopoly" and "cartel".

Anti-competitive actions should be combated, but why do people insist that anything has to do with being a "monopoly"?

To draw a comparison, in criminal cases the courts will not determine if an accused is "a bad hombre" – they will determine if he committed the crime or not.

This is like those people (and lawmakers sadly) who try to define any sexual offense as "rape". Thinking that the severity of the crime is only tied to one single word.

> there are 200+ exchanges. you're saying all of them are fully collateralized?

In crypto? No. Because it's a marketing term there for brokers. FTX was, at the end of the day, a broker. (As is Coinbase and the other "exchanges" for how most people use them.)

In finance? Yes. Most exchanges (all in the U.S.) don't handle settlement; that's done by a clearinghouse, where the counterparty risk lives. They're fully collateralised [1].

Sign matters as well as magnitude. The pulse created will have both a positive and negative part - waveform sort of like --^v-- and so you can get either direction bit flip. It's not equivalent to connecting a battery to the pin; EMI's more like AC in that it goes both directions.
Show HN: Cloud Development Environment Using Gaming CPU – Codespaces Alternative
A few months ago I started my journey to bootstrap Lapdev[1], an open core solution to manage remote development environments that you self host. It didn't really work out.

Still I was developing Lapdev on a AMD Desktop CPU machine hosted in Hetzner, because I know it's more performant and less expensive than a public cloud. And it strikes to me that all existing cloud dev env providers like Codespaces and Gitpod all use the cloud, i.e. server CPU for their offering. So I quickly did some performance tests on Codespaces and Gitpod, and comparing them to my AMD box. Unsurprisingly, my AMD box can deliver 2x the performance, given the same CPU cores.

So it's clear to me that I should work on a cloud dev env with AMD high end gaming CPUs, as there's no such offering on the market. If you've got remote development in your workflow, check us out on https://lap.dev/ and see if it can boost the performance for you.

First off, thanks for continuing this exchange with me. Text communication between strangers is fraught with miscommunication perils left and right, so hanging in there is a really nice gesture. Cheers.

It's so weird, though. Everything disagreeable you point out with my comments, I kind of feel like is true of GP's comment. It casually dismisses the content of OP, injecting a strawman about a "metrics". Wore still, it just touts normative and relatively mainstream opinions about better vs. worse thing, without even offering up a hint as to what these supposed metrics are supposed to be measuring.

That's a dick move, IMHO, and a common one at that in these array language posts. I think we as a community do ourselves a disservice by allowing ourselves to propagate such echo chambers.

Which is all a pretty different message than @arcfide (eloquently) attempts.

Please note that nowhere do I attack GP or GP's comment specifically. If you're inclined to reread my comments, please note that I really do try hard to delineate ideas and cultural trends as the target. Heck, I even own up to being part of those trends and culture. Where you have thought I say "you", try rereading it as "we".

Anyway, cheers!

Even your example of discharging a capacitor can end up with a pulse both directions, caused by the inductance of the wires.

In this specific situation, there's no common reference level, and so the induced pulse will go both directions. You can think of this as being about the edges of the pulse being the parts that actually cause radio to be transmitted, and there's both a positive-going edge and a negative-going edge on a pulse.
I have been doing Ruby on Rails for ~14 years but ~10 years ago I was confused and I picked up Nodejs thinking it is the future of software development.

It only took me a couple of months to realized what Ruby on Rails offers & the vibrant ecosystem it has. I quickly pivoted back to it and never looked back. I'm very happy with that decision.

Take that plunge and you will not regret it later.

Ask HN: Where can I find a good primer on the cryptocurrencies ecosystem?
Hi,

I would like to read about the cryptocurrencies ecosystem, especially things around Ethereum. There are so many things going on in this field like the so called Layer 2, sharding, side chains, smart contracts. I am also interested to learn more about projects around Ethereum like Uniswap, dYdX, 0x etc.

Where can I get a nice overview of all this?

Thanks!

The "Global internet users" graphic near the bottom of the article is an impressively bad example of what Edward Tufte called "chatjunk". Not only is it visually pretty awful, it's really hard to tell where the data points are supposed to be. (The surface of the "piles o' desktop computers"? The top of the hominid heads? The neck of each hominid?) And I like how the vertical axis apparently starts at minus one billion users, suggesting that shortly prior to 2005, there was a point where there were negative one billion users.
The key takeaway here is that you can't correctly process a string if you don't what language it's in. That includes variants of the same language with different rules, eg en-US and en-UK or es-MX and es-ES.

Sad as it may be, I imagine that lack of desire also comes from consumer demand. Most people don't care about running those 15 year old games, so what's the motivation?

For archival's sake, you should be able to seek old APKs and run older ROMS through an android emulator. So the minority of those who care have options.
