Ask HN: How best to learn about high performance computing?
I recently was turned down from a job that seemed great due to my inability to answer questions about optimizations that are needed for high performance computing.

Topics such as:
* Cache locality
* pointer arithmetic
* memory management techniques
etc...

I realize most of the companies who are looking to hire a candidate with this skillset will want the candidate to have experience with these topics as opposed to learning these techniques on the job.

I currently don't have this knowledge, but I want to learn. How best can an individual learn these techniques if they don't work on these types of systems?

Thank-you
Yes, Adobe publishes SWF specs. You can extract text, links, pictures, etc. out.
> Can you imagine how cool it would be to manipulate Windows services from the WSL session?

This was a little confusing, in some ways, because it came right after "being able to list out processes to kill". A Windows Service is a lot like a `systemd` service.

In the scenario he envisions where you could see windows processes within WSL[0], it'd be possible to write a script that could invoke the windows-equivalent command to stop/start services and print `systemd`[1]/Windows services side-by-side, but you couldn't make Windows services "work" with `systemd` tools. Somewhat obvious, probably, but it caused me to raise an eyebrow for a second so I thought I'd mention it.

[0] Was it this way in WSL1? I don't remember, it's been too long.

[1] Last time I used WSL2, I ran openSuSE Leap; not sure what the default ships with.
> Closed groups are not indexed by google, so everything that's written disappears in the Facebook silo.

Not only that, but they're not indexed even by Facebook itself. Facebook's search tools are and always have been a joke. Probably on purpose.
Many paid SSO/IDP solutions offer this, e.g. IDaptive has an App Gateway that has worked well for me, and Azure SSO has a more limited one as well. You run some agent behind the firewall, it talks outgoing to the cloud sso provider, and your end users get proxied through with the benefit of authenticating to the IDP before they even hit your service at all. Great way to slap 2FA on a lot of things without having to worry about VPNs.
Screw them. Install uBlock Origin.
Uhhh, what problem does this solve?

That’s my concern. I would 100% sign up at this price, but I’m doing the math in my head:

They offer 4GB VMs; Assuming they’re oversold and using a good backblaze-pod like design, they can fit ~32 drives per U. 32 * $5/mo is $160; Assuming they’re paying $50/U and the customer’s guaranteed bandwidth is included in their colo cost, that gives them $110 gross margin. Cost of drives is retail - If they have a better supplier that’s a few $ more, but not a lot. The hardware to run that is another real cost. I doubt it costs less than $2000/U to outfit the hardware; It doesn’t have to be beefy but SATA slots add up.

That gives a payoff time of ~18 months. Doable, but not amazing. At a scale of a few dozen racks, this could be a lifestyle business, but it’s sorta marginally so. Assuming a hardware lifetime of 3 years, you start breaking even halfway in. Lifetime margin is about the cost of the hardware - $2000/u. If this is a single man show, about 2 racks (= ~3000 customers) gives a reasonable “salary”, but the upfront costs are high.
Is that an upper bound? My Ubuntu 20.04 console sessions on WSL2 consume a couple tens of Mb.
The mailing list thread posted by another user indicates it being present in 1992. References to it being military slang.
You have the causality backwards. "Fake news" was not a Trump invention, it was a criticism originating from the political left against people that supported Trump with fake articles, such as the false article of the pope supporting Trump before the 2016 election.

Trump, as he so often does, co-opted the attack and used it offensively. The same media that was fretting about fake news was suddenly being called fake news, which was when they decided they no longer liked the term.

The Washington Post made this public and explicit, saying the media should no longer use the term they had popularized just months prior:

As a <30yo that grew up posting, moderating, and administrating forums (when I wasn't on IRC or Teamspeak), the decline in quality pales in comparison to the uptick in spam over the years. Maybe it's just different audiences but the spam was eventually so bad I moved multiple communities off of forums that we'd used for years and years- and got at least an hour a day of free time back in return.

In my experience spam is easily the biggest contributor to the death of forums, most groups just don't have the resources to keep their heads above water.

I see people complain on platforms like Reddit or Discord about one or two spam messages getting through, I don't think they realize how good they have it. A channel I follow on YouTube just got a single spam comment which one of his followers responded to, and he made a 3 minute video about it.

Can you imagine making a 3 minute video every time a spammer registered for your forums?

> there’s no magic that keeps Apple customers buying apple products.

So then what's the magic that keeps Google users using Google products if they stop producing what their non-paying, but ad-watching customers want?

If the answer is "anticompetitive practices", I don't deny that at all, but that has nothing to do with advertising as a revenue model. Just look at Microsoft, they have long been the champions of anticompetitive behaviour and yet they didn't really use advertising as a revenue model until recently.

> Google will try to make you happy insofar as it helps them get more money from their paying customers, but the moment there’s a conflict between between the needs of their users and the needs of their customers, the paying customers will always win.

The needs of the users are the needs of the paying customers, that is what I am saying. Without the users there is no opportunity to have paying customers, period.

> your relationship with Google has more in common with a cow’s relationship with Nike than a shoe owner’s relationship with Nike.

No, that is a totally misleading analogy and I think it perfectly demonstrates what is wrong with this argument. Users choose to use Google products in exchange for ad impressions.

It sounds like you already know the answer - focus on details. Don't give a full product demo, go in depth on the actual work you have done recently. If that means digging into intricacies of one small feature, then that is what you do.

This is probably a good thing because it'll force companies to move to other video platform that let them host videos without ads. It might drive up competition in video space, which is a good thing. Youtube has been monopolizing video space for far too long because they were operating without much regards for profits, killing their competitors that don't have a deep pocket.
One of the nice things for users on MacOS is devs are forced to keep up and use the latest standards pretty quickly so everything just works mostly as long as you aren't using an unmaintained tool or updating OS on day one. On Linux I have to use Wayland to properly support different screen DPIs but then a bunch of software hasn't updated to use the new apis because they can just tell the user to revert to X.
I don't think so. I recently had a very similar problem to solve (converting old PM4 files from my college years) and had to dig around for a way to run it.

I ended up using a mixture of DOSBox and Windows For Legacy PCs under Parallels:

This article seems to laying a lot of blame/duty on Apple for reasons I don't think are very valid. The author even recognizes the fact in the piece.

If there is anyone to lay a duty toward, I would argue it's the developers (Big developers, like Adobe) who could contribute directly in providing code/documentation for their legacy formats.
> Lack of clarity often comes in the form of ambiguity

This is sometimes useful. Mathematicians have precision ingrained but this often repeals pupils.

When you start with 'f is a continuous function defined in R of x defined in R, and for each x ..." - well, I am lost. This was the introduction of differentials in my son's high school.

I am a physicist, so I started the other way round, by talking about speed, how it is calculated, how one can get more precise by shortening time and that, eventually, we get to the exact momentary speed.

My son started to ask all kind of question such as how to "get closer" on my wavely drawing, to which I told him "good question - this is possible only when we know the function d(t)", etc.

It is only when he understood the general reason for differentials to exist that we went back to the conditions (continuity, planes, etc.). He actually deduced the continuity constraint himself because he understood the "why".

My math told told us once "I will show you a neat trick that you will not understand this year, but when you understand it next year it will be way less useful to you. Just know that it works only when this and that".

So lack of perfection is sometimes useful for people to understand something at all and not wander off after the first two introductory sentences.

which is fine if there's not competition (e.g. internal software).

I am thinking may be next year or the year after. The MacBook Pro will get new Design, at 16" and 14". ( I hope instead of going thinner they could stay within the current cooling TDP )

Then the MacBook Air will have a 14" as well, before a 12" MacBook Air is introduced at a lower price range, possibly at $799.
FB, et al are about selling you to advertisers, not being useful.

I have no idea, but I'm guessing archiving useful information would "suppress engagement" by actually answering your question rather than generating tabula rasa discussions for the nth time.
WSL1 is like the "kernel personalities" in other operating systems like the BSDs. WSL2 is more like Linux for Windows, because it is the actual Linux kernel in a VM, hypervised by Windows.
Yes, I am indeed accusing you of a strawman. You seem very much in the discussion to win it, whatever that means to you. I can only hope that, having decided you are victorious, you'll now leave me alone, because none of your comments seem particularly productive to me.

The differentiable programming framing is quite useful in the scientific simulation space, because it lets you couple traditional physics simulations to either neural surrogates or some sort of bayesian model. Enough of it is happening in the Julia world that were very actively improving the compiler to support it.
Not sure on this particular format but apparently the majority of file formats on those older now dead programs were basically just raw dumps of data structures in memory and not actually something well defined like the xml/json files we have today.

Makes reverse engineering them pretty difficult when you have to work out how the original software was laid out.

NTFS performance leaves much to be desired on Windows too, it really hurts for workloads dealing with lots of small files, such as programming.
Bingo! It’s boil-the-ocean level crazy to attempt to recreate the environment for a particular file, when the sensible approach would be to just have the file format and it’s reader/viewer software be open so it can be recompiled or ported to any new platform. The blame/responsibility lies not with those innovating on hardware, but those who have created brittle software systems which have no ability to adapt to the changing environment.

Yet another example of how holding binary artifacts is not functional equivalent to “owning” software.
> "Because the style may change, but the underlying data won't."

What's the difference? It's the same typing, whether you create styles in CSS or just class names in the HTML. Designing the first time vs changing it later is the action.

The rest of your comment seems to be ranting other issues. CSS can't be split, that's the point. It's been tried often but it just doesnt work in reality and is part of HTML which also covers presentation concerns.

I don't see what JSON APIs have to do with this. It's not the most common case but it does actually mean you have an API to use without the presentation if you really want it, so isn't that exactly what you're asking for?
I've read a million times that the difference between Python and Ruby is that in Python there is one right way to do things, and in Ruby there are many ways to express yourself. But then in the real world, most companies betting on Ruby add RubyCop.

I'm not sure that that such an entity is truly necessary to get a lot of the functionality. However, in the case of git, I'd guess 95% or more of users in effect do have a such an entity.

Thats not exactly how this works, financially speaking.

TL:DR the more successful Lambda is with placement, the more they get paid per ISA ("financed" or not). Incentives remain aligned, even if they get paid before the student does.

.

>It's a nice idea to align the incentives of the school and student, but the current implementation doesn't do that if the school sells/finances ISAs

But the current implementation _does_ do that.

Debt is always "scored" before being sold off - which factors in to how much the debt ends up being sold for.

In this case, the scoring depends on how much gets paid back per ISA, which is subsequently determined by the placement success. Here's a couple of ways this _could_ happen:

• If the overall placement % goes up - so more debt (ISA's) is actually paid vs not paid (b/c conditions aren't met)
• If the avg. salary per placement increases - so more $ is actually paid per ISA (with respect to the $30k cap)

If Lambda can show success in placement, meaning more return is made on each ISA, then the ISA's will be "scored" higher.

As to whether or not they are sold upfront - thats a nonfactor to me. If Lambda doesn't do its job training and placing people, they don't make money. Either way this still holds true.

Also, all the financing could be happening and student STILL will "not pay any upfront tuition" and "won't pay until they are earning $50k" or more a year - as Lambda advertises.

I think part of the issue is that all the things that men fare worse in that you listed out are the results of a society that is controlled by men. Men are doing this to themselves.

The problem for women is that the negative societal aspects of their lives are not controlled by women - it's still largely controlled by men. Same for people of color in the US - their lives are largely controlled by white people (and specifically white men).

I think even for the wildest of misogynists out there (I am in no way implying this is you or anyone on HN) it's hard to argue that the world would not be drastically different if it was mostly controlled by women.
Interesting, I'll check it out. Thanks for the link.
Somewhat tangental but I am very jealous of a high school that introduces differentials. My high school didn't have calculus - lack of interest and no one qualified to teach it.
