> If I were running it as a 100% legal/safe operation I'd invest the balance in short term treasuries. If you multiply tether's liabilities ($61.9B) by the current 1 year treasury rate (0.09%), you get $55.7M, which seems like plenty of money to run such an operation.

If we're playing that game I'd do the same but invest in tax-free municipal bonds and the like which can currently earn 3-5%. That would earn you $1.86 billion on the low end. Keep staff & expenses low, pay everyone insane salaries (eg 5m per year is less than 100m given their staffing levels), and coast until acquisition. Everyone gets rich now and again later when you sell.

That's what is so ridiculous about Tether... they have plenty of ways to go legit if they wanted to do so. Heck even if they were only spending half of every $ they took in to actually back the Tethers (and pocketed the other half) they could have invested in the US Stock market over the past four years to make up the difference, then presented public financials this year proving they have enough currency, bonds, stocks, and paper to fully back every Tether. They'd have pulled the same trick lots of big time crooks did and gone fully legit. The fact that they aren't doing that indicates they're either really stupid, really greedy, or both.
This is true, but even in US locations with high population density, we still don't have symmetric multi gig connections. Instead, we 1 or 2 choices for a wired ISP: generally cable / DOCSIS and DSL. And around here, PSTN copper is literally rotting on the poles, so DSL is out. Fiber is supposed to be installed "soon" (I estimated 1 to 2 years.)
Stop using git blame to look up who authored code, it's not a useful tool. Use git log -S <string> to search for changes to that line (then repeat with the previous version of that line, until you find the original author), and/or git log -L to track changes to a code block. Don't waste your time with git blame.
This is something that took me a bit to realize. I've made some friends at work that do things outside of work, but building relationships/friendships outside of work are usually more meaningful and last longer.
Yeah, nah. I’m not typing 5 levels of “structs” for one or two properties I want.
That's common. Most tools like Magit make it easy to dig down through multiple layers of formats, renames, refactors and typo fixes to find the commit that actually introduced something.

It's usually called "blame previous revision".
`interface` isn't a type, it's the keyword used to declare an interface:

type Foo interface {
Foo() int
}

`interface{}` is simply a shortform for an interface with no methods.

Put it on a blockchain then.

Edit: I'm serious. Blockchain is exactly meant for application inside zero-trust environments. If you think it's impossible to put a video on blockchain, just have software making hash-fingerprints at regular time intervals and save those on a blockchain to make tampering with the video evident.
That's the hard part for all of this: if you are building an unlock mechanism the first question you need to ask is how you build a UI which clearly communicates to a user that they are likely giving control of all of their data, location/camera/microphone, etc. to whatever they're installing.

The scammers who push malware under the guise of tech support, free porn/games, etc. are effective enough to compromise millions of people and that's before you get to the question of what it'd look like if a government started pushing access for monitoring. How many people might consider installing something which this guy they met in a coffeeshop says will protect their messages from government surveillance? Now consider how many people might have malware installed by an abusive domestic partner, and where control of the device would extend to hiding the existence of spyware.

This is not to say that Apple is acting without self-interest here, only that I think there's really a pretty nasty market failure making it quite difficult to reconcile someone being able to make choices about their device with a fairly high risk of compromise with potentially significant consequences.
How much communication is there between the Julia compiler team and the LLVM team? I don't get the impression LLVM has been very sensitive to Julia's needs so far.
I've been working from home almost completely since 2009 and worked about half time from home since 2005. It's definitely not for everyone, but the only way I'll ever go back to an office is if it's literally the only option left. For me the biggest reason is the staggering amount of wasted time associated with going into the office generally, but specifically for software dev work it's an environment that is stacked against you.
It is not well-known that some large insurance companies have a specific tactic that they employ against out-of-network medical groups even for pre-approved or emergency work (Some practices that are out-of-network will charge exponential multiples for services which is another grievious issue).

The large insurer will send checks for goods & services directly to the patient, rather than to the practice(s) that performed the service, even if this is a fairly reasonable cost.

Patients see a check for $8,000 and $25,000 that is supposed to go to the trauma surgeon's practice that initially stabilized the patient, followed by the Plastic Surgeon's practice that spent 16 hours, 2 titanium plates, and a large number of titanium screws, and biologic implants reconstructing the patient's face. And, similar for the small consults $300 consults to Opthamology and Neurology that are common to severe head trauma involving optic nerves, relatively minor brain injures and significant facial trauma.

Instead of providing it to the practice to pay for the plates/screws, and delivered services, the patient spends the money. Then the patient gets sued.

This is not uncommon unfortunately - even for medical practices that TRY to be in-network with every single insurer, AND medicare/medicaid.
There is a fundamental tension here because a) doing this stuff properly takes a long time and b) lots of undergraduate math teaching is "service" teaching, meant to get students up to a level where they can do the manipulations needed in other courses.

This is why there is typically separate Calculus and Real Analysis streams in undergraduate - the former is needed for all the hard sciences and engineering, the latter for math students and fellow travelers who really want to understand what is going on and be able to prove things properly.

Typically the analysis stream will start with a pretty in-depth look at what real numbers actually are (spoiler: weirder than you thought) and the implications of that. You get a much better understanding this way but you don't cover ground nearly as quickly.

Harald Bohr won a silver medal at the 1908 Olympics with the Danish football team. He was also a notable mathematician, an editor for Acta Mathematica and he discovered the fascinating Fastperiodische Funktionen.

Sports and academics were not unusual in his family: his brother Niels (not an Olympian, but a known physicist) had a son Ernest who was an Olympian in 1948 (hockey).

Unlike his father and brother Aage, Ernest did not win a Nobel (he was a lawyer).

That's not your or my decision to make. It's the prosecutor's.

And on this one, I'm with her. Everyone "defrauded" by Tether is and was a willing participant. The wound has been cauterized by banning Tether from New York. Damages can settle themselves through the courts using the injured parties' own resources. (Not taking into account that many of the presumed "injured" would object to that designation in the first place.)
Except hydrogen fuel cell vehicles lost already. There's no point comparing to them because we don't live in a reality where they're going to become a thing. If you want to play the "what if" game, that has its merits, but it has nothing to do with the world we presently live in or the proximate future.
Maybe. But it's not a significant enough factor to say "you will not become a grandmaster unless you’re starting out as a child".

I'd wager that free time (and overall lack of responsibilities) is the vast vast vast vast majority of what factors into children excelling at chess.

Am I a bit off when I say "they'd have about the same chance as a child", all else the same? Maybe. But it's certainly closer to reality than the original post I responded to.
A good open office can be very good, when each person gets plenty of space around them, things are generally quiet, and management isn't always wandering around (everybody wants to check HN or reddit occasionally, but feels weird doing it when management can see). Defaulting to a setup where most people can't see each other's screens is a nice touch, and the aquarium is cool.

Tesla's inflated stock makes it easy to acquire companies, but Tesla lacks cash flow so it is hard to acquire debt and enter into long-term contracts. Few companies are going to accept $150M in today's Tesla stock as collateral for an agreement to purchase $30M in parts every year for five years unless you give them the stock today so they can unload it. The idea that Tesla has some magic beans when it comes to batteries seems to be driven more by Tesla fanboys than by people in the biz (quick reality check: Tesla's batteries are made by Panasonic and not Tesla, oh and last month Panasonic dumped the entire hoard of Tesla stock they had been holding.) Tesla has some useful long-term agreements with Panasonic but they seem to have far less battery IP than you are suggesting.

Yes, batteries are a limiting factor, but there are a lot of companies out there not named Tesla that know a hell of a lot about lithium battery cells and unlike Tesla some of these companies actually produce batteries.

There's also the costs and externalities of shipping fuel to fueling stations all over the country in perpetuity, there's no additional cost to "ship" electricity to homes or charging stations.
The article makes no mention of the legal justification backing up any of these debts. They aren't due to straightforward contracts like nearly every other bill, as that would require up-front rates. And so they must be due to some state law that empowers hospitals to create arbitrary post-facto charges for whatever amounts they feel like. Part of the focus of healthcare reform needs to be on these state laws that enable the arbitrary billing racket in the first place - if they were eliminated, much of the opaqueness of the healthcare industry would be forced to change.
I like the double-entry bookkeeping analogy, but isn't it true for all tests? In fact, as the article explains, in the old days it was a specialized QA department (different from development) which wrote tests often just based on specs, and the barrier (also called black-box testing) was there precisely to have independent verification. It seems to me that this argument favors the old methods and not TDD in particular.
Can someone from the core team chime in on the general thinking around the type system/trait stuff? Most of the rest of the complaints are actively being addressed or have been thoroughly discussed, which leaves me unconcerned.

Haven't heard much about the type system stuff in years, or it's just been "duck type and thtt works ok". Is that the consensus? Honestly, that's a pretty valid perspective also. Julia works amazingly well and there's no other contender for the same combination of speed and composability. But, I feel like things could be easier/smoother.

Is there a general design plan, or maybe there's a desire/intent to do something but it's going to require iteration down the line?
Hopefully this isn’t from delusions but there ARE SE positions with very bad pay especially when what class you eligible for depends on where you live. Software positions at worst can be lower class.
Yes, tone provides a lot of information, but can someone accurately ascertain whether that tone will lead to problematic behaviour? I don't know. I would want to see some sort of research before accepting that this does what you say it does.

Certainly, if someone were to say something sexist or racist in an interview, that would be a red flag. But I doubt most people would do that. So maybe you are able to weed some people out, but probably not very effectively, and you will likely still have to have other mitigations in place. In additions, you will have "false positives" in the form of people being misread. For example, they could be saying something genuinely and the interviewer thinks they are lying or being sarcastic. Are the false positives worth the true positives? I don't know. That's why I would want to see actual evidence.
By solved I really mean "in commercial use", there's probably a lot of research let to be done, but people are already verifying TLA+ specs all day everyday.
Average age of a car as of 2016 was 11.6 years and climbing, so it seems like the vast majority of those in operation would easily hit the offset threshold.

What if that person's “decision” was being tricked by a scammer? Or being in an abusive relationship? Or living in a surveillance state?

I want people to have more control over devices but there are some non-trivial threats which millions of people face which are currently defanged by things like the OS not allowing malware installs, or hiding the use of various sensors or data access, etc.

Yes, this is the utopian goal of political anarchism and arguably much market theory. Unfortunately, it's only as good as the right selection of local rules, and it's very possible that what's good for maximizing one thing has many untoward side effects or requires such a degree of homogeneity as to become unpleasantly restrictive.
Regulatory credits down. Critics have continued to say Tesla loses money if not for regulatory credits, so seeing those shrink while still growing is strong.

> the maps are generic in the same way that they already are in Go.

Go maps are actually not generic in the same way they are in other languages, there is just a single map struct with type descriptors used to do some compiler magic: https://dave.cheney.net/2018/05/29/how-the-go-runtime-implem...
I reread this twice, but I am still not sure how this helps the insurance company through. Is there something I missed? Or is this intend to cause administrative issues for out-of-network medical groups?
The short answer is that changing the type system to allow multiple inheritance (traits) involves solving some really hard and open-ended problems (eg method specificity). Solving this is probably breaking, and requires a ton of work on a problem that might not even be solvable. If I had to guess it will be solved by the language that replaces Julia in 20 years.
Made over a billion in profit, and margins are close to 25% which are great.
Probably true, and goes to complaints from police officers that they're also expected to be counselors as well as enforcers.

On the other hand, asking someone to go into a situation that may put themselves at risk (for some cases of welfare checks) without appropriate training or equipment (or leaving the distinction of which is which to some third party not on the scene) doesn't seem like a good idea either, and at the point where you have a force that's equipped to protect themselves and possibly restrain others, that begins to sounds a lot like a police force, so I can see why they just use the police.

There's probably some solutions along the lines of different shifts for those with different training with different load outs, or additional trained personnel in sets of police, but all of those also have some problems I can see and don't address officers being dispatched that are prone to use force because of a prior altercation that day/week or trauma at some prior date.

I appreciate your opinion, but you use words like "impose"/"force" and bring up prison.

A lot of people were hired on the condition of going into the office and I find it all the backlash from employees after being asked to go back into the office a bit absurd.
Undoubtedly true. I have 10,000 song files with the same problem!
Same. For me in the states, the argument is an easy one, because the plan in the states is pretty much "sell your house to afford your medical bills even after insurance and hope you don't run out of cash before you die". Our cultural attitudes towards elder care are most glaringly obvious in our healthcare system.
" own bills"

The problem is that Hospitals can charge any amount they feel is correct but you cannot find that out UNTIL AFTER the service is delivered. Yes you could ask for cash prices but try doing that at a regular hospital and see how quickly you get them in a clear and concise manner.
I mostly hope you're right, good luck. Post your thesis here when the time comes.

Reddit is definitely not the whole world. It's heavily dominated by people from the US and western europe, and heavily biased towards the the mainstream western propaganda narrative. Reddit is an active target for propagandists (i.e. intelligence communities).

I'm very interested in this male vs female subject with regards to games (chess, video games). I don't think it has to do with intellect, but there has to be some biological difference.

They are supply constrained until the Texas factory opens. Literally a 3-6 month wait if you go order one today. With Texas open they are on track to double sales if demand stays strong.

Cybertruck comes next after Texas is pumping out 500k units a year, and they have the next battery pack ready to scale. My guess is summer-fall 2022 by the slow news on the topic.

An associative / non-commutative hash function over lists. This would mean that the hash of a list, H(list1), could be "concatenated" with another hash, H(list2), to find the hash of the concatenation and be equivalent to H(list1+list2). I think such a construction could be huge for cryptographic verification of data in data structures while avoiding baking in incidental details about the data structure itself.

I hesitate to link to it because I already know of a potential attack, but I played around with an implementation that does this with matrix multiplication over galois field elements of reinterpreted hash digests [1]. I mean, the associative / non-commutative part works nicely, but I expect that factoring the matrix is possible which makes it utterly useless as a cryptographic primitive [2]. "don't roll your own crypto" would apply, but I'm obviously not using such an academic exercise in production.
