I think folks who grew up on the internet are unaware of the awesome power wielded by the better business bureau and see Twitter as a last ditch effort to extract accountability from companies. This is quite fair since a lot of companies have massively scaled back their CS in terms of revenue expenditure on labour (hiring cheap overseas call centers or "helpful AI") and in terms of the unexpected costs those departments are allowed to raise - unless you seriously make the person on the other end of the phone's life hell you're not getting a replacement part.

As a result they turn to twitter where, historically, companies are so shamed by the outcry and tempted by the PR potential that they quickly give in to demands for whatever the customer asks. The BBB is an amazingly effective way to signal to a company (and to all of their large customers) that their CS is absolute trash and underinvested - but, that said, shouting on twitter is easier.

This article seems to miss the biggest point though - outside of the small segment of rabid twitter users, nobody gives a damn what's going on there except for the occasional meme that makes it over to Reddit. I have no idea why companies would be concerned with their "brand presence" on twitter - practically nobody who isn't going to complain about you is going to see any of that.
I've read the post before, I've seen the talk, and frankly it's been addressed a number of times. It's the same silly nonsense that they've been touting for decades ie: "a bug is a bug".
> most people would've given up in between

Nah, that's the most fun part. Once you have one kernel that works and one that doesn't, you can be pretty sure that you'll eventually find the cause of the bug. The part where I would have given up is the "trying to reproduce" part.
The website mentions some good courses, personally I love Richard Borcherds' YouTube channel[1] for both undergraduate and graduate courses. No frills, exceptionally clear, (mostly) bite-sized lectures that cover a good range of material (especially in geometry).

Something that might interest HN's demographic is Kevin Buzzard's Xena Project[2], centered around proof systems (in Lean). The natural numbers game [3] is particularly fun IMHO. I don't know if it counts as learning materials per se but it's certainly instructive.

This makes a ton of sense to me. Seeing how you solve a difficult problem with someone collaboratively is a great insight on how you'll continue working together, because that's exactly what you'll be doing. It's also very valuable to see how someone receives suggestions or criticism and how they respond. We'd actually like to build a lot of these concepts into Litebulb, ie: responding to code review requests?

As an add-on, an interesting question one of our clients asks as a conversation starter is "what's the most technically complex project you've ever worked on?". This question sets up the space such that the candidate is the expert (since they've already worked on it), and it almost becomes a session where the candidate teaches the interviewer.
The main problem I’ve observed with fallback is that 3.0 devices plugged into 3.0 ports sometimes get detected as 2.0 devices. Sometimes there’s a spontaneous port disconnect and the reenumeration causes it to be detected as USB2.0.

If I recall correctly this was primarily only happening with a non-standard optical repeater cable so it could be the cable was doing something unexpected (eg 3.0 enumeration was taking longer than some timeout and it was going into 2.0 mode).

In general though users preferred functionality, even if performance was reduced.
I feel older for the same reason - it sucks watching the internet of my youth slip away.
You have it completely backwards.
LaTeXit looks great, I'll have to try it next time I'm on a computer.

Currently I use Anki for the same effect.
I think if you need that kind of control than perhaps Python isn't the best choice most of the time. I think that's perfectly fine too.
My recollection is that there were absolutely insane compression ratios demonstrated from fractal compression, but that they required hours of manual (human) work doing pattern matching, finding the proper transformations between look-a-likes, etc.

I think it's totally plausible that modern AI techniques could replace the need for free graduate student labor.
I expect we'll start to see software that will include code that detects Russian character sets, Russian timezones, Russian internet addresses and will refuse to work if unlicenced. Most likely they'll be able to bypass those but a significant majority won't be able to pirate due to lack of technical knowledge.
So can we assemble one of these on the moon already?
At this point, does anybody need to give any extra reason for why they can't trust this government or why it's a bad idea to give them power that can be abused so easily?

I think this assertion is terribly outdated for 'serious' (Console/AAA) games and 'professional' game developers. I can remember as far back as 2007 interviewing for an XBox360 job, and being asked to describe in detail how I would keep all the threads busy. A professional game developer working on a serious high-detail/low-latency game would not be taken seriously if they don't know how to make a work queue.

What you say is probably true of most indie games. That's a whole different world. But the 'state of the art' is perfectly accurately described by 'batched and parallel workloads'.
No recommendation on probability. Thats strange given that the author is a physicist and fundamentals of modern physics rests on probability. My recommendation is the classic "Probability Theory, The logic of Science by E.T.Jaynes" which is a Bayesian formulation.
You are free to peruse the reports by pretty much every national nutrition & dietetics organization in the world; they already did the hard work of combing through and evaluating all relevant studies in that area.

Any individual "assessment" of the scientific literature by someone who doesn't have scientific training in general or in that particular area is much more likely to result misleading or even dangerous conclusions.
> In free press societies, you need the will of the people to go to war.

Sure. And this consent can be produced when there is a need for it. “Proof” is not the missing component.

That American basketball player who the Russians detained? Casus belli. The cyber attacks? Casus belli. Shelled civilians? Casus belli. The NATO country cargo ships which got hit and sunk? Casus belli.

These are just the ones I can think of. A proper state aparatus can come up with many more and probably even better ones. Government officials will leak the background, solemn faced politicians will demand justice while friendly journalist will write up the whole thing in the most hearth wrenching way. If they want to they can.

So why do they don’t want to? Is it because the Russian army is so powerfull that we think we can’t overpower them? No. Is it because the Russian air defences are so advanced that they cannot be picked apart? No. So what is it which makes the west avoid a direct confrontation with Russia? Why are they doing this strange dance of supplying weapons to Ukraine and hurting Russia with sanctions, but not directly engaging with them troop-to-troop? It’s the Russian nukes.

> You misunderstood, or simply ignored the word “public”.

I don’t think so. You won’t “prove” anything to the public through detailed technological explanations. A fig leaf of deniability might be an interesting roadblock in a criminal prosecution where things have to be proven “beyond a reasonable doubt”. In a situation where there is a governmental will to engage in a peacekeeping mission (read: send troops to fck the Russians up) the evidentiary level is “can we find an authorative sounding voice in the whole government who can tell the right sod story to enough guilable journalist to sell the people on it”. That is such a low level of “proof” that one might as well assume it can be met nearly always.

Journalist won’t pour over the attack binaries using Ghidra to make an assesment about the relative probabilities that it has the signatures of being created by this or that advanced persistent threat group. The ones who would demand that level of rigour before publishing won’t get the scoop. The ones who are selected to spread the message will have a lovely hour with a very charismatic “expert” who will walk them through just enough of the detail to sound right but not to get bogged down in unnecesary complications. This chat will get translated into a single line in their article, maybe something like “experts at the National Security Agency matched the unique signatures of the cyberweapon to the advanced persistent threat group Tippsy Bears, a known front of the Russian Federation.” Followed by two pages of hearth wrenching human angle story about innocents suffering needlesly. That is the “proof” the public might get.
I dunno, at that point, are you really doing math? Math is proof. Now, granted, nobody expects you to know exactly how everything is proved. But there is an expectation that you can prove most of the stuff. Otherwise, it's very easy to stray from the truth into the plausible-sounding, but incorrect.

That said, you're absolutely correct that more justification and motivation is important. So much of math can be taught with problems from physics, computer science, etc. Perhaps a good book for you would be Concrete Mathematics by Knuth? I haven't read it but people swear by it.
> They simply called them "defence contractors" instead, and promptly returned them all.

"All" means 100k of initial invasion forces? Or few hundreds who provide security to commercial objects in Iraq?

> Russia has already annexed territory.

They occupied territory, it is not recognized by many countries as annexed. Now they want it to be recognized.

I love Arches National Park, great hikes and fabulous geology. Now to learn that it sings, wow.
Interestingly the ascent of linear algebra is a relatively recent thing. I have an engineering degree but while I was certainly exposed to basic matrix stuff, never took a linear algebra class. When I was an undergrad, you took differential equations in addition to basic calculus for engineering. (You needed for system dynamics among other things but it was very cookbook.)

Linear algebra became a lot more interesting once you had cheap computers and Matlab.
No one cares about BBB these days.
One of my first bits of code I shared online was a scraper for userfriendly.org that would download every comic since the beginning of time.

It was incredibly bad and inefficient (I didn't sleep between calls and just brute forced the image name which led to 90% 404s). Within a few days, UF announced that anyone doing wget scraping would get IP banned.

I was just a kid, but it was so jarring to see something I did cause problems. I learned a ton about being a good netizen. Thanks UF and sorry for the trouble!

This seems a bit contradictory!

> your support for the deaths of thousands

I don't. The Russian aggressors do.

> I’ve been anti-Russia from Day 1

Judging by your post history, that's extremely debatable

> Ukraine is fighting a war they can’t win

Again, debatable. Russia can't 'win' in Ukraine. Whichever way to take it, even if they manage to take the large cities, it is impossible for them to 'conquer' a country, 1800's style. That's just not how things work anymore. You can't stifle dissent at this scale unless you go full nuclear and if that's the case, we're all fucked anyway (including Russia). The more time passes, the more strangled Russians are going to be economically, so there is a non-zero chance of Russia collapsing or Putin getting ousted before Ukraine falls.

> If China rolls up onto US mainland with auto-aim drones, I’m hiding, and if surrendering is on the table then I’m definitely surrendering.

Then I'm glad you're not in charge of US defenses. We really don't need cowards around here.
I am under impression that current Iraq government is not puppet, and even more pro-Iran than pro-US.
As I said, 1%. And in those cases using hydrogen makes little sense.

Emergency vehicles of most types don't need that however. And in many of the cases you mention swappable battery packs are an option as well.

But we have to realize that compared to all consumer and fleet cars, 99% of all trucking is the vast majority of fuel use in transportation.

Extreme long range trucking is the exception.

In most cases you would make the hydrogen into methanol and you can keep mostly the same engines.
Well, it's more like they forgot the words and are just humming.
Regarding the power supply I suspect that right now we are in transition just like when Apple was late on updating updating the design of the late intel notebooks. It seems like they know M1 was on the way and focused their efforts on that knowing that Intel was going away. If Intel was not going away my guess is that they would have resolved the later thermal/design issues of the laptops sooner.

Same goes for this power supply. We are probably moving towards even lower power consumer chips and while the current power supply is pretty small, just imagine a more power efficient base line M2/M3 chip + GaN based power supply. Maybe they could power the machine with a tiny cube shaped PSU or just have a usb-c connector coming out of the back.
Ruby and Python being used about equally as often, but Ruby (primarily Rails) leading to 3x the market cap in aggregate...

It's important to look at both the numerator and the denominator :)
This looks amazing and I’d love to try it, but our app only works once you’ve logged in. We do have special accounts made for Apple testers etc., would that work for you as well or is this unusable in our case?

EDIT: My apologies I didn’t see the login radio button at first. That said, our aunt mechanism is a 2fa kind, and basically our “special” testing accounts means generating a code for manual input so you don’t need the second factor. You will need instructions for how to do it though, so the question still stands, could we use this?
Russia didn't even held their end of the bargain for the Budapest Memorandum when they annexed Crimea. They really have nothing to complain about it.

Yup! That's why we recommend using Litebulb as a mid-funnel tool. Initial screening should be with a hiring manager (or a founder if it's an early stage startup), final meetings should be with team members/managers to get cultural fit. We just try to make the technical coding evaluation part easier.
You mean like so Windows can ruin your Linux? Why trust hardware isolation when software will do!
The energy density of a battery is so low though. That means a lot of capacity must be dedicated to batteries instead of cargo. Meaning you need more trucks.
My question, as I know very little of Japanese folklore, was whether this is more like the Easter bunny (just a game) or the second coming of Christ (something people actually build their lives around).
Where are there exercises?

I just tried clicking on some linear algebra topic, but it seems there are just videos

Offshore wind has been growing quickly for 20 years. Deindustrialisation started in the 80s. None of this is new, really.
I disagree - BBB will get you a response pretty darn quickly. It's a pretty common B2B rating platform so most businesses take their image there a lot more serious than twitter.

Just because it's not a post-tech boom company doesn't mean it's irrelevant now that we've got the internet.
Those are the accepted figures, not simply taking Russian state provided figures at face value.
You mean quacks and grifters like Dale Bredesen, MD, researcher in Alzheimer's, who recommends everyone omit oils except olive, avocado and coconut oil entirely from their diets because they promote chronic inflammation?

(Bredesen probably does not maintain that coconut oil is good for you, just that it doesn't have the problem of contributing to chronic inflammation.)

The claim was that rail works if there is enough traffic between two points. That claim is false. It's false even if it's the same traffic at both points.

Hub and spoke is a specific kind of a set of pairs of points. (One point in each pair is in all members of the set.)

Hub and spoke doesn't work unless there's enough traffic to each of the endpoints.

> Western European nations practice social democracy which developed before and independently of Marx.

When we look at Germany and their universal healthcare system, it was developed in the 1880's under Otto von Bismarck and their monarchy in a direct response to the fears of a Marx-inspired socialist uprising.

A lot of what developed in Europe was inspired by Marx and socialist organizing and developments on the continent.

Yeah... when I said I would go back 20 years, this is what I was talking about... sort of... Those were the great times! Maybe I am just old and nostalgic and it may be something everyone does, but for real, those times had lots of issues, too, sure, but there were great things.

There are different types of stats. I took a stats course in my grad engineering program. Not being the best person at math I think I probably struggled with the math sufficiently to get distracted from the concepts. When I breezed through a stats course when getting an MBA I understood the concepts much better--though the professor was almost certainly better as well.
You can’t understand much about statistical inference without calculus.

It’s all integrals over pdf’s. A lot of integration by parts and other things in the core curriculum.

The FedEx/UPS/Amazon/Doordash vehicles still require fuel. The trucks bringing food and supplies to your local grocery store use fuel. The fertilizer used to grow your food required fuel. The construction and maintenance materials for your current dwelling require fuel. The plumbers, electricians, cleaners, trash collectors, locksmiths, etc require fuel. The container ships that transport good from China require fuel.

Literally everything you use in life, even if you're the most shut-in Hikikomori on the planet, is downstream of fuel. If the fuel cost increases are transitory, you might not notice it. But if they persist, you absolutely will.

With the XP calculator, I use F5-F8 as shortcut keys for changing bases whenever I want. The Windows 10 calculator doesn't even do anything with those keys in scientific mode.
> They see the beautiful TV picture of brave Russian forces fighting Ukrainian nazis...

I never understood that part of the propaganda:

to free a nation from nazis who elected a jewish president??? ("Zelenskyy is the first Jewish President of Ukraine..." https://en.wikipedia.org/wiki/Volodymyr_Zelenskyy )

Sounds completely crazy to me?

I'm assuming that Ukraine's president's religion is known to Russians (as apparently russians and ukrainians are very near/related to each other etc..., stated by the propaganda itself), how can that propaganda (and therefore as well the other related propaganda) not fall apart on its own, to still be accepted by the population? I totally don't get it... .

Good luck and thanks a lot for your post!!! :)))
