I worked in supercomputers for some time (molecular dynamics simulations, among other things). I am not convinced that the additional cost is worth it, with the exception of a few things. For example, if you're a nation-state and you need to make a submarine that is 5% quieter, or 5% faster, or whatever, for national defense purposes, having a CFD simulator that can work with sizes of problems or turnaround times that are significantly better can be a strategic advantage.

There just aren't that many codes that can take full advantage of these monsters, and there are other, cheaper, faster ways to obtain roughly the same results. For example, in my ex-field of molecular dynamics, it seems like you can get away with minimal interconnect by running many simulations and pooling statistics across runs, which needs a bunch of IO bandwidth but doesn't need supercomputer-style interconnect.

What's interesting is that supercomputer hardware is really great for high performance ML training, but the supercomputer folks came to that realization later, and only after companies like Uber ported the tensorflow distributed implementation to MPI (Horovod). And most of the ML people were poking around with slow interconnects. Now it's converging- the largest use of supercomputer-style systems in 10 years will be ML training, not physical simulations.

Supercomputer spend has only limited impact on forward technological process.
I use a Book 2 as daily driver but to be honest I would prefer the HP ZBook I had before. The Book is very unstable with multiple monitors, the docking station constantly runs out of USB resources, when I detach the tablet and reconnect the display settings get messed up and I spend ten minutes reconfiguring and overall it lacks speed compared to its configuration. Really not a good experience for a pricey high end laptop.
If your takeaway is that GDPR is the problem in this equation, I can do nothing other than strongly disagree. It quite possibly could be better drafted, but oh boy is personal data hoarding by companies a huge problem, and would certainly not be lesser without oversight.
I recent switched to a Linux desktop after doing the VM dance on MacOS for a few years and I can't believe I didn't do it sooner.
> Except going forward, those are going to be the only APIs available

That is false. There are already library implementations of legacy OpenGL, modern OpenGL, OpenGL ES, WebGL, legacy Direct3D, Direct3D 10/11, Direct3D 12, Vulkan and others.

Major players like Microsoft, AMD, Khronos, Valve and others already depend and employ people on providing those APIs and libraries long-term.

Those APIs are not going anywhere, even if a hardware vendor decides to only provide a low-level one (which is understandable, by the way...).

> They are still there, but not longer map to existing graphics hardware.

They have never mapped to hardware, so there is no real difference between now and then.
Haven't been following php in years, but from back in the day I remember many different approaches trying to introduce threads and none could guarantee safety for the fundamental reason that the language itself is implemented unsafely. The runtime was done in C with unsafe features from the start. So process forking was the only sane reason to run php. I don't know how much of that is still true, though.

Can you share the architecture and stack?

What form do these jobs have?

How do you manage workloads?

How do you manage resources? Do users have quota for compute and storage?

Do you use GPUs? If so, how do you deal with malfunction?

Is this a distributed processing? Are the machines heterogeneous? What do you use for that cluster?

What if a job requires dependencies? Do you create a compute environment on the fly or do all jobs have the same dependencies and these don't change much?

How do you do data governance? Is the data read only? Do you have an API to fetch the data from the job code?

Ask HN: What certification to study as a developer to work remotely
I am basically a developer. I love algorithms / designing / coding / debugging. Not a fan of doing UIs. Plan to look for a different job in two years, yeah I know long horizon there. Not enjoying my current job, management, but need to stay for 2 more years.

As such I have time to re-enhance my technical skills. Ideally I would love to work purely remote. So what developer skills are most in demand that can be done remotely?
Infiniband is pretty neat for a given use case but that cable length kinda killed it for many data center use cases.

> simply going to the customer and asking them, "Out of these 10 things, if you could have 3 by the end of the month, which would you pick?"

This is only simple for a limited number of businesses. If you're building a product and not selling a service, it's much harder to nail down what is actually important to potential customers. Even talking to existing customers about new features is never a fool-proof way of getting the right prioritization.

Even when you do have a customer you can go and ask, they are rarely a single entity. The person in charge of the buying decisions may think some features are important, but the people who will end up using the product may have other priorities. Even then, prioritization may be hard on their part. If I were building a word editor for you and I came and asked whether word counts are more important than page numbers for you, would you be able to give a confident answer? Would your colleagues give the same answer? How about prioritizing both features over some stability work (e.g. you get both page numbers and word counts, but the product is still a little crashy)?

Yes. UWP already mostly uses WinUI 2.0 I think. 3.0 will expand the minds of applications that can make use of the component library and provide a way to gradually incorporate newer controls into older technologies (WinForms, WPF etc).
Yeah. That's a long way from tuition is already deductible. Some tuition is deductible (or can be credited) if your income is below a limit. Up to $2,500.

I still think a contaminated sample is more likely, all else being equal. Not saying this is impossible, but would like to see at least a few other cases this early. If this patient had not been to China then there must be some.

And if this turns out to be a true positive then it indicates the virus is so contagious that it spread that far and wide, that quickly, that overall infection must be much more widespread than is thought.

What I want is irrelevant. I have as much say about what happens in the EU as I have say in US politics despite being from the EU. The politicians will do something stupid regardless and then years later not understand why things are going poorly. Meanwhile the Germans and French will love it, because it screws those evil evil American companies. So, the regulators might as well design APIs. It's hard to imagine that it would end up any worse than their usual.

Ask HN: Looking for a particular data science textbook
Several years back, I stumbled on a data science textbook that I believe was written by a non-programmer. It was a pretty thorough "for dummies" introduction to using Python to understand data analysis, but there were some notable features:

+ The text was big -- it was not a dense book.
+ The topics covered were not extremely comprehensive -- it was not an O'Reilly book.
+ It featured a huge number of stock photos, including people -- notably of every race, gender and identity. For a book written by a nerd for sort-of-nerds, this really stood out to me.

I can't find it in my old emails, messages or bookmarks. If any one has any leads, please let me know!

This is a failure in leadership at UberEats. Uber has more than one revenue source and delivery is in high demand, UberEats is severely losing to DoorDash in food delivery, despite Uber having significantly more resources than DoorDash. Uber has billions in the bank, Doordash only has hundreds of millions. At the time of this posting, Doordash is currently number #13 in the App store, UberEats is sitting at #62. Uber has access to capital and reserve in the bank. Reserves are often used for a rainy day, well it is pouring now. They should be using their position to gain market share during this time of peak demand for deliveries, should not be losing to DoorDash.
As far as I can tell, this is not a controlled study, but just an analysis of a bunch of people who took the drugs at a pretty low dosage. The analysis doesn't (and couldn't) make any conclusions about HCQ improving patient outcomes vs. not using HCQ; but rather just tries to assert that it didn't make things worse and we should therefore do it because China says it's a good idea. Without any baseline it's not clear to me how one could evaluate these claims. Sounds just about as useful as the previous paper.

As an aside, I do feel like the mean age of poor clinical outcomes, 69, feels a bit low relative to my expectations.
I believe Flat UI was the invention of Albert Shum (as reported by CNET at the time, he came up with Windows Phone Metro UI). You can see his articles here: https://medium.com/@alshumdesign

I wish this were the case. Instead all Microsoft products have switched to the ugly Flat UI, including Word, PowerPoint, Excel, etc.
Microsoft appears to be pricing their hardware in line with Apple now? $1599 starting price for the Book? I get the quality and the features are up there but the price is unappealing.

the GDPR does apply to a camera in a bar. As long as it is used exclusively for security and data purged regularly, it can be claimed to be required.

Certainly the bar owner cannot distribute the videos without explicit consent. And yes, that can be problematic in many cases (for examples, capturing faces of people in a concert).

Agreed, the meaning of .ai domains isn't set by us.

Formally, .ai is a country domain. However, it's broader meaning is cultural - again, not set by us.

By popular usage .ai has become like .io, used informally as a startup domain. We're really just following that pattern.

Our users don't tell us they felt deceived by the pattern, they never even mention it as a concern. Instead, much concerned feedback is around data-privacy.
>But maybe that's suboptimal in the sense that I pushed myself too hard initially, so I am fed up with that activity and don't feel like doing maintenance at all.

Yep, that's what I think. If you are oscillating for no reason you are doing it wrong. That's typically the yoyo effect people often experience when optimizing for their weight.

Humans do a really poor job at optimization in general. Quite often following a simple PID for control just make these oscillations disappear, and allow the optimization to continue instead of being stuck.

This is a simple model (quadratic), so it has its limits. Context switching shouldn't be a problem. Ideally you would have a zero cost to context switch, but if the cost is non zero, it only increase the variance but you should reach still your optimum as long as you remember that you are not just optimizing for the task at hand but for the combination.

The other limitation is when you have non-linear effects, but they are usually adverse, meaning big oscillations are more likely to result in an injury, than in an acceleration in progress. But sometimes, they can be beneficial like avoiding over-adaptation.

>Can you elaborate on this?

Which brings me to the satisficer vs maximizer point. There are often two school of thoughts when you optimize a problem that has constraints.

Once the problem become more complicated some people will assume a simplistic model and go with it, while other will try to find the best one before going with it. General-structure oriented vs detail oriented.

You can stay in the primal representation where you respect the constraints, then improve while respecting the constraints. Or you can switch to the dual where you give yourself some slack in the constraint while occurring a cost for violating the constraint that you add to the objective. You can also stay within the admissible region using some barrier method.

When you are working in the dual you are already juggling with multiple objectives.

You try to satisfy the constraints simultaneously focusing on those actively being violated, usually once all constraints are satisfied you are happy and stop maximizing even though there is still something to grab. If you want to progress further, you give yourself some additional constraints and satisfy again. Basically you are trying to land in a good-enough(TM) region of space.

The maximizer will aim for the peak. He will optimize for the sake of it. Instead of expanding the problem to a more interesting one, he will try his best to grab that extra-performance point on its limited toy problem. Once he reached the optimal point he knows that he has some slack left and only then he expands the problem to another dimension.

Sometimes he finds that deep peak inside a shallow valley, but most often he is spending a lot of energy just to make the satisficer look bad.

Engineering will likely be hit on the team/project-level, I suppose? If you need some amount of tech people to run your operation, it's hard to say "well, we're doing fewer rides, we can now fire 50% of tech". But they may well be cutting back the side-projects and exploratory R&D.
That's because for many of us outside of the EU, it doesn't mean much besides yet more email from content providers regarding changes to their privacy policies that I just delete.

But we've built a world where a large fraction of the population has [apparently] willingly traded their privacy for free product.
