If you ever intend to have anything to do with machine learning, computer graphics, or work for a quant firm[1], yes.

If you want to work on adtech, CRUD apps, or uber-but-for-catsitters startups, probably not. I have been working on two out of the three for a decade, and in all this time, I haven't had to use a lick of linear algebra.

From an academic standpoint, it's arguably a more useful course for your general education than calculus (Which is a requirement for just about any degree), but less useful than statistics.

[1] If you ever intend to work for a quant firm, you should probably take a lot more math courses than just linear algebra.
If you're truly competent you'd just take one of the myriad of jobs being thrown at you with no strings attached. Why on earth would you choose a potentially temporary setup rather than an immediately permanent one?
So how come nothing happens to these massive companies doing it?
If you're interested in graphics, animation, simulation, machine learning, or other topics, knowing the concepts in linear algebra will be worthwhile.

Most higher-level math will be easier for you if you have familiarity with vector calculus and linear algebra, so if you're the kind of person who benefits from a structured class when learning new/weird ideas, it's worth studying in school. (I'd also generally recommend a course in probability and statistics)
Many commenters here are missing the point. All the measures that were taken against Greece (for its own good, of course), were, theoretically, about improving the competitive of Greece and solve the problem of the public debt.

Nothing of that have happened. The public debt problem has not being solved and the Greek economy is a disaster. So who is responsible for those mistakes? They failed in their predictions and their failed in their goal (if what they say in public about their goal is the truth, of course).

It seems to me that if we leave all those politicians that decide to be "hard" on the Greeks without punishment we will have a clear case of moral hazard.
They have widely used enterprise software too. I have to agree though, the dichotomy is pretty funny.

Parc was an "extension" or "outgrowth" of the ARPA (before the "D") sponsored computer research in the 60s that was catalyzed by Congress overreacting to Viet Nam protests and changing ARPA's charter for the worse.

ARPA/Parc as a community had the best and most enlightened funding for computing research starting in 1962 (Parc started in 1970), and a very large percentage of the familiar technologies of today -- including personal computing, tablets, dynamic OOP, the GUI, the Internet, etc -- were invented by it.

The best (and pretty accurate) book about this remarkable group is "The Dream Machine" by Mitchell Waldrop.

Bob Taylor, who had been a director of the ARPA computing research, looked for a way to fund some of the "ARPA Dream" projects that Congress was curtailing, and found Xerox (which wanted to set up a longer range research lab).

Taylor was particularly interested in recruiting a number of the young Phds that ARPA had funded, and I was one of them.

My intention was to point out that lending is a two party relationship and both parties have responsibilities. The tendency in my experience in these discussions is to put too much blame on the borrower and too often put very little blame on the lender.

The motivation of the German and French governments was that German and French banks not suffer. And of course the leaders of those countries cared more about their people than the people of Greece. This is natural and part of the psychology of being part of a nation. We ended up with things like:

https://www.reuters.com/article/us-eurozone-greece-warships-...

At any rate, both parties are at fault and both parties ought to have suffered. From my perspective only one party suffered.
Agreed, I do not see their "budget" website as sign they lack credibility, I see it as a sign that they are focused on their work.
It quadrupled after joining because it borrowed money from Germany and other countries to buy German cars and other goods, not unlike the early stage of Bretton Woods. It had the lowest debt level before joining, like a fat cat to be squeezed by EU bankers, which was also why it was fast-tracked in joining the EU when it clearly didn't meet many clauses of the Copenhagen Criteria.

But when push came to shove in 2008, the debts were exploding not in Germany, but in Greece.
Strang is an excellent teacher and this an effective course for coming up to speed in Linear Algebra fundamentals.

I watched every lecture and did most of the homeworks a couple of summers ago in preparation for taking grad ML courses at Carnegie Mellon (10-601 Intro and 10-605 Scalable ML). The foundations that I built from Strang's course were essential to my success later.

I worked there for 3 years.

First year we received close to $1200 and in 2004 being a poor college kid this was an amazing bonus.

The 2nd year there was a series of high value thefts so we only ended up getting like $250 or so.

Our Lost Prevention employee who was just some guy who looked at security cameras all day, went out of his way on his own time to research all the same stolen items looking for them in local craigslist/pawn shops and finally e-bay.

He found one account on e-bay that coincidentally was selling all the same items our store kept missing! (Some of these were brand new laptops)

The account name of the seller was firstinitial+lastname+numbers

He took that account name, and cross referenced it with our employees and found a match. He then forwarded all this information to the police.

I remember one day going to our monthly manager's meeting (once a month had a store wide meeting where managers went over everything with all employees)

We did the entire meeting, free pizza and donuts, talked numbers shrink etc, and the best part was that on the last page of the presentation they had the guy running the Lost Prevention department come up to talk shrink. He explained everything above and then flipped the presentation paper to the last page which had the e-bay account giant sized on the paper. He said this is the person who has been caught selling everything and they will be taken care of.

We all turned around from our meeting and there were police offers waiting to arrest the perpetrator on the spot.

Said person was a 20 year old who had everything handed to him on a silver platter. He drove a $40,000 car his parents paid for type of thing where most of us had rusted beaters to drive around.

He was doing it only for the thrill, worked in the electronics department so he was able to steal things from the cages when trucks came in and you are supposed to unload all the pallets.

I just remember that meeting so vividly because they let the kid go through everything, thinking everything is normal and I wish I was able to see his face when his username was shown right away.

I won't forget his face and cries as he was being arrested saying, "You cannot prove that is me!" even though it was his first initial + last name and year he was born in.....

I find that at least in The Netherlands the vast majority of job offerings are quite conservative in their 'stack'. It's nice that they are now okay with React rather than only Angular, or Python instead of just PHP, but finding a Clojure or Elixir shop is still much like finding a unicorn. And my impression is that this is true in most of the EU.

OP here. I completely agree with that. The goal of ModalEdit is not to emulate those verb-noun commands. VS Code's commands operate on selections, so it is very cumbersome to turn them to work in Vim way. Instead, you should try to mimick something like [Kakoune][1] which is another modal editor that uses the selection as command target.

I'm sure ModalEdit doesn't tempt any hardcore Vim users to use VS Code. But there are a lot of VS Code user's who have used Vim and like idea of modal editing. Having an extension that you can configure from ground up is the value proposition I was aiming for; not to make a poor man's Vim clone.

> is it really just a matter of increased number of execution units running at once causing weird power and heat issues?

That's been the root cause of all the previous AVX weirdness I'm aware of. It's probably the case for these Threadrippers, too. Modern CPUs have very high power density and run at pretty low voltage, which results in insane current delivery requirements.
Correct. I don't understand why this contradicts the argument.

"Computers can learn complicated games with more computing power"

"Compute power goes up"

"Computer learns more complicated game"

I mean, if you really think of AlphaGo on an extremely high level, it's just a really elaborate way to create and learn a dictionary of moves to take under different circumstances. Of course that's going to be completely dependent on amount of memory and CPU power.
I have used this extension a bit and it works great as far as I can tell. Whereas with the older popular VS Code vim extension, I would get broken behaviour within minutes of use. And I am not a particularly proficient vim user, this would have just been navigating, using visual mode a bit, correcting some stuff.
Good thing, too, that nobody stepped out in front of their car, like a kid chasing a ball, as they did their ad hoc experiment.
Because it doesn't rely on both the user and developers to do some yet to be determined 'right thing' for the CPU to behave in a consistent manner. While you are correct that some people want absolute max performance per watt, I would argue that no one wants a CPU that behaves unpredictably or inconsistently. An option to disable one or more power saving features that result in this issue (assuming that's what the issue is) for those who just need maximum performance could be a desired solution for some. While others, possibly most, would be willing to take a short term performance hit from a stall to maintain the best overall performance per watt characteristics.

I believe people arguing "politeness" are missing the point, though. What I most value is "dialectics" (not sure if that term is commonly used in English).

I. e. the willingness to entertain the best argument against your position in good faith. Two people who are excellent in doing so (and familiar to HN) would be Scott Alexander of slatestarcodex, and Matt Levine at Bloomberg.

(Someone rather bad at it, usually arguing against some caricature of what he imagines his opposition to be, and generally tending towards the "either unactionable, obvious, or wrong" end of the spectrum is, well, Paul Graham.)

I do fancy the moral superiority exerted by some against the Greek populace profiting by a bad line of credit.

Do they also protest German and French banks betting on Greek bonds that yielded very high interest rates? When you own a financial instrument with great upside it means it also carries a lot of risk. So, according to some, profiting from high interest rates is dandy but when it's time to pay the piper (your borrower made YOUR risk materialise) they don't want to get bankrupt, just transfer back the risk you took in the form of debt.

And of course the loaned money is not used to re-invigorate the local economy. It is going back into the French & German economies because the local economy of Greece is destroyed and their companies go in and undercut the local competition. e.g That's how shit-show supermarket chains like LIDL wiped out of existence very solid Greek supermarket chains that existed and were profitable for multiple decades before the financial crisis, but then had to do mergers or shut-down.
Genius plan. And that's why Greece didn't deceive anybody to get into the Eurozone - the members just looked the other way.

The Greeks should have had defaulted and let the creditors who where profiting all those years from junk bonds (because that's what Greek government bonds were) take the hit. They would have recovered much better by now.

Finally, it's bizarre to me how many people still believe that governments represent the 'people'. No they don't, they represent their friendly neighbourhood bankster - as long as they get a good cut of the money - and the special interests which fund elected politician campaigns. Greek people preferred a default over loan bail-outs from the start. They protested heavily and in the majority but were completely ignored. Numerous MPs had the audacity to admit that they never even read the terms of the bailout. As the great George Carlin said, "They are a big club - and you ain't in it buddy"
how is that any different than alcohol? sugar? gambling? standing in the sun? how is that different from work? are you profiting off of the people that put together the building you are sitting in?

Genuinely trying to understand your position here: It's "authoritarian" for a scientist to claim, based on their good faith expert opinion, that a particular scientific question is "more or less settled" if...you disagree with their assessment? Surely that's not what you believe?

In comparison, I'd say Strang's class is more formal and feels more like work, and those videos will be more fun while fullfilling the same purpose, to give you a lasting understanding of what linear algebra is and where it might come in handy.

With all the corruption going around I would not blame them. (even without it I would not blame them regardless. There are many people all over the world -including me- who consider taxes thievery)

Anyway, please do correct me if I am wrong, but wasn't it only the rich/rich companies that did that? Similarly to how Amazon, Google, or Apple for example pay almost no tax.

He could. He was committed to a Grexit, which he calculated to be substantially better for Greece than what it has now. Then he got immense political pressure and death threats to his family.

How would W3C stop this?
Okay yes. You can be in your 90s and opening up regedit or writing rust programs using async.

But for the majority of people at that stage of their life, who don't really care about the technology and haven't really followed it closely, it's a valid concern that random A/B testing and continuous version updates that change how you use programs are an alienating obstacle to using computers.

From the comments on this thread, a lot of people who do follow technology and who are used to being treating like this also hate it. It's not a stretch that, for less savvy users don't know what exactly it is they should hate will just assume it's computers that are at fault and choose a different tool.

Not increased number of execution units, but increased number of transistors, yeah.

A normal multiply does 1 number at a time (32 bit for simplicity). AVX2 can do up to 8 multiplications at a time. That's a huge amount more transistors firing all at once and that causes the voltage to start to droop.

AVX-512 takes that even further and now it's 16 multiplications per unit, oh and Intel moved from 1x256-bit unit per core on Haswell/Broadwell to 2x512-bit units on Skylake-X, so it's potentially 32 multiplications at a time - 4x as much as AVX2.

Basically to prep for that much power being drawn all at once, the chip has to switch to a higher-voltage mode to account for the voltage droop caused by all those transistors switching at once in one place. It takes time for the regulator (on-chip Fully Integrated Voltage Regulator or motherboard VRM) to wind up the voltage far enough.

https://travisdowns.github.io/blog/2020/01/17/avxfreq1.html

https://travisdowns.github.io/assets/avxfreq1/fig-volts256-1...

At this level behavior is intensively analog and thermals/voltage both significantly affect transistor current draw and switching time, which feeds back into thermals and power consumption/voltage droop.

This gets even more problematic on 7nm/10nm type nodes and especially in GPUs where you are doing a huge amount of vector arithmetic all the time. Essentially it is no longer possible to design processors that are 100% stable under all potential execution conditions, or even under normal operating conditions, so you have to have power watchdog circuitry that realizes when it's getting close to brownout/missing its timing conditions and slows itself down to stay stable. That's why AMD introduced clock stretching in a big way with Zen2 (despite the fact that it's nominally been around since Steamroller). NVIDIA piloted this with Pascal, AMD piloted it with Vega and brought it to CPU with Zen2. You simply cannot design the processor to be 100% stable at competitive clocks anymore. You have to have power management that's smart enough to withstand small transient power conditioning faults.
