I genuinely think 90% of frontend developers should not exist: the web would be better and companies would have better products.

I include myself in the frontenders, I do terrible apps which should just be simple static pages with a sprinkle of js - in my defense, I need the money and nobody listens to me, they say this is modern frontend development.

For my tech not-savy clients I can deliver awesome and simple solutions without using the dreaded R framework.

I still remember the day I met John Warnock as if it was yesterday.

John's humility, despite his monumental success, taught me to always keep my feet on the ground. His vision inspired me to push boundaries in software development. But above all, it was his passion that kindled a fervor within me to harness technology for change.

John Warnock's passing is a massive loss for the tech world. My heart goes out to his loved ones during this time. His legacy, however, will continue to shape the industry, inspiring countless others just as he had inspired me. Goodbye, Mr. Warnock. You will be missed.

If light acted instantaneously you would have to calculate the effect of it's rays everywhere all at once, which I think is quite expensive given how vast space is.

However, since the speed of light is miniscule compared to the size of the universe you can ignore all but the most local interactions, and just schedule a computation sometime in the future when you know that the light vector will interact with something.

While instant calculations would perhaps make for a simpler system conceptually, the speed limit and locality principle ensures that less processing power is needed (at the cost of a lot of memory).

Yes, and I'd take it further. What I'd like to see more of in physics texts is presenting a problem before offering the solution. Too often you get what amounts to a laundry list of techniques and ideas, which are the components to the answers to hard problems, but the student isn't motivated to learn them. If you present the hard problem first, the student may flail around and realize: I need something to help with this! Now that they know they need it, and why, you can give them the tool that fits the bill. For example, I think calculus is probably better learned after trying to write down some force laws, and perhaps doing some numerical analysis. Then when you learn them you realize those nice closed-form solutions aren't busywork, they are huge labor saving tools that eliminate ad hoc labor intensive analysis.

I would also deemphasize the more mathy parts of calculus - do you really need a deep dive into continuity or the fundamental theorem of calculus? Eventually, yes. But it's just like programming: you're not going to need to understand language theory or ADTs or category theory or lambda calculus to write your first program. Or your second. And, IMHO, you should only reach for this understanding when you realize you need it. Otherwise, it won't integrate well into your toolkit.
Personally, I use rust for the ability to go as fast as C++ but with far fewer footguns. Not to mention that I personally really enjoy how they made algebraic data types and package management first class.

I suspect that if you really spent time learning rust that you'd really appreciate it coming from C++.
Briefly ignoring the economic aspect of this, we have to stop using countries as reference points against the whole world. It's like when I'm told "Bad thing X happened, and affected an area the size of Belgium. A WHOLE COUNTRY".

What do I do with this information? Sure, Belgium is big, but is it like, big? It turns out that it's... does the math... roughly 0.00006 times the total area of the Earth. That doesn't sound big. And if bad thing X happens every year, it would take more than 16000 years to cover the Earth, or 800 if we say 95% of the Earth is water anyway. That timeline also sounds manageable.

I'm not trying to spin disaster positively, but will someone please just start using "affected area / total potential area" or something, instead of yardsticks and football fields.

How does datasette work with unstructured data?

I work with large text datasets, and I typically have to go through hundreds of samples to evaluate a dataset's quality and determine if any cleaning or processing needs to be done.

A tool that lets me sample and explore a dataset living in cloud storage, and then share it with others, would be incredibly valuable, but I haven't seen any tools that support long-form non-tabular text data well.

Your message is more misleading than the GP.

Many architectures sold today still claim unaligned accesses are optional (e.g. all ARM pre-v7, which includes the popular Raspberry Pi Zero). Not to mention that even if they are supported, not all instructions support it (which is the case today on all ARM cores and even on x86).

From the architectures and instructions which may support it, it may have a performance penalty which may range from "somewhat slower" (e.g. Intel still recommends stack alignment, because otherwise many internal store optimizations start giving up) to "ridiculously slower" (e.g. I once had to write a trap handler that software-emulated unaligned accesses on ARM -- on all 32-bit ARMs Linux still does this for all instructions except plain undecorated LDR/STR when the special unaligned ABI is enabled).

And finally, even if the architecture supports it with decent enough performance, it may do it with relaxed atomicity. E.g. even as of today aarch64 makes zero guarantees regarding atomicity of even atomic instructions on unaligned addresses (yes, really). To put it simply because it is a _pain in the ass_ to implement correctly (say programmer does atomic load/store on overlapping addresses with different alignments). This is whether they cross cache lines or not.

i.e. it's as a bad as the GP is saying. You can't just put one example of one processor handling each case correctly to dismiss this claim, because the point is that most processor's don't bother and those who do bother still have severe crippling limitations that make it unfeasible to use in a GP compiler.

And there is still a lot of benefit to packing things up... but it does require way too much care and programmer effort.
I only became reasonably proficient in physics when I took the summer off between undergrad and graduate school and spent three months, six days a week, ten hours a day, doing nothing but working through four years of undergraduate physics curriculum by solving problems from my textbooks.

There is no substitute for solving problems.

Yes, and I think this leads to a more sophisticated analysis than PUE gives us, because a shop like Hetzner puts more of the burden for reliability and availability on the customer, compared to an Amazon or Google who internalize as much of the redundancy and replication that they can manage.

An example of where the PUE analysis really fails: I have two facilities, one on each American coast, and they operate in a primary-spare arrangement. This is far, far less energy efficient than if I have 20 datacenters all over the place and I am prepared to lose 2 of them at any time. In the latter architecture I am using much less energy, but enjoying much better reliability. PUE does not capture this type of architectural waste. It also fails to reflect the problem of burning megawatts because you are running your logs analysis pipeline in Perl or whatever.
Defaulting to "prove it" is not anything anyone needs to "answer for"....

I see the growth of VC backed companies leading to the downfall of stable 20 year career path and loyalty to employee quality of life with everyone chasing this lottery model of hitting it big using VC money and selling out the company with an idea and exploiting more and more people to get it done.

How much of this innovation is baed on tech that was created and funded with public money and gov grants and then privatized when it became commercial and profitable. Sure seems like we stopped advancing the science of the commons when VCs started growing in the 80s along with bank deregulation.
I'm not an expert either, but I like to think that the speed of causality is the speed at which a piece of information (e.g. a particle, a gravity wave, etc) is traveling through space.

So the speed of light / gravity is essentially the maximum speed of causality, because nothing can travel faster than that.

EDIT: Or you can think in terms of how information propagates through spacetime. In this point of view, the speed of causality is always the speed of light, for everything, including particles with mass.
I’m not sure datacenters have a great incentive to reduce energy costs (a lesson I learned the hard way after investing in a DC energy optimization software company). People costs are much greater than energy costs. Electricity just doesn’t cost that much in the grand scheme of things. If additional energy spend is necessary to ensure uptime, the choice is an easy one.

Internally, the compiler could represent it however it wants. LLVM IR's load/store instructions just have an "align" property, which is usually sizeof(the type), but can be set to 1 to mimic memcpy (and indeed llvm/clang immediately translate a memcpy to such - https://godbolt.org/z/7T46a6aqT).

Though it seems that, independent of this, it assumes that an int* in general will be 4-byte-aligned, so e.g. https://godbolt.org/z/aWTEd4s3K still has an "align 4" despite using memcpy. So one must also cast to a char* before using memcpy() to actually have it work. yay for more footguns!

Even though Susan Rigetti says you don’t need to learn calculus first, I would recommend it -— or learn it concurrently with the introductory mechanics course. Mechanics is so much more enriching when you learn the mathematical language that was created to describe it.

You’ll already be one step ahead by the time you get to the second course, which is good, because you can strongly benefit from learning vector calculus at that time. I really enjoyed the text “Div, Grad, Curl and all that”.

"naively you could turn the entire cut GOP into i-frames couldn't you"

Yes, but then you'd have to render the result into a truly uncompressed format and it would have to stay in that format perpetually. If you wanted to deliver in another lossy format, you'd actually lose quality across the entire file instead of just the one GOP.

What I'm curious about is whether you can cut in the middle of GOPs, recompress the afflicted ones, and then concatenate the stream back together without recompressing all GOPs. If the file specifies a 12-frame GOP, cutting any GOPs is going to break that cadence. So can you have, say, a few thousand 12-frame GOPs... then an 8-frame GOP... then go back to 12-frame GOPs?

Update: Did some research and you can have "adaptive" GOPs of varying lengths: https://docs.aws.amazon.com/mediaconvert/latest/ug/gop-struc...
Since you seem knoweldgeable... can I ask a potentially dumb question?

Does anything stop a rogue network from adding a BGP peer configured with the AS number that's listed in the ROA and then propigating those anouncements how they want?

Maybe prefix or path filters on the rogue's upstreams, but my (weak) understanding of RPKI says if the destination ASN matches, it's an acceptable route, and I don't see anything to validate that the announcer actually is the AS owner?

Overall BGP is built based on a high assumption of trust, and RPKI seems to be very helpful for accidental hijacks, but might not help for intentional ones. OTOH, if Iran only wants to hijack within the country, they might just effectively require networks within their purview to accept the hijacking announcements without regard to RPKI (and the external networks who enforce RPKI would ignore those announcements by default, if they leak)

This is just a ratio of power fed into computers vs not-computers. It doesn't measure the effectiveness of power->problem_solved. If you were running P4 space heaters but delivering power to no other equipment, you would have a PUE of 1.

I decided to start self learning theoretical physics late last year. I have been now studying physics every day for almost a year (before and after work). I did have to brush up on calculus and matrices but it came back very quickly (within a few days) after a 25 year gap so I'd say don't let that discourage you.
This is exactly how next.js works. But even more importantly: Why not use GraphQl in this situation? This is exactly what it excels at:

2. The frontend can request a page worth of data from diverse entities in a single go.

Data centers are the cost. I worked for an entity that automated key operational workflows. They went from 15,000 employees in that division to 4,000. The energy cost of those buildings, overhead, etc far exceeded the datacenter, and the datacenter cost and use gets whittled down every year.

This would be the case if they attempted to register the work as the author (which is the only way to register a copyright work! You can't register if you're not the author!)

Rather than 27 (or however many) books, an ambitious student may be able to use just one big-ish book: Ian D. Lawrie's "A Unified Grand Tour Of Theoretical Physics". This even has a little 18 page "Snapshots of the Tour" which might be a trip down memory lane for those who studied physics long ago.

Of course, it might also be impenetrable if you haven't had prior exposure to most of the material.. I have zero experience trying to teach physics from it.
> Inspired by Box<T> in Rust, the std::box<T> would be a heap-allocated smart pointer.

so, is it the pointer that is heap-allocated or the pointee? frankly, i find this article somewhat incoherent, and importantly, it lacks code examples illustrating what it is talking about.
And that power grid is intelligently and efficiently managed using those same data centers.
std::vector<MyType> is a pretty good 'box' like container. Dynamically allocated and applied RAII semantics. If you only want one instance, then dynamic allocation shouldn't (?) be necessary.
I've noticed before that "physics" as in what is taught for a physics degree has gaps which make little sense to me as a mechanical engineer. Continuum mechanics (including both fluid and solid mechanics) is unfortunately nearly entirely absent aside from some basic things like Hooke's law and Bernoulli's principle.

In my view, what's taught for a physics degree is more of a historical accident than a selection of the most important principles. In an extraterrestrial civilization, the boundaries between engineering, physics, and chemistry may be entirely different.

Dismissing Navier-Stokes as just a consequence of Newton's laws and thus unimportant can be extended further towards dismissing a large fraction of what's taught in physics degree programs. An undergraduate physics student may get more education on Bose-Einstein condensates (which are just a consequence of quantum mechanics :-) than they do on Navier-Stokes. The Navier-Stokes equations are a lot more important than Bose-Einstein condensates in my view.
How would you go about aggregating all that information into a single national number? Without the CDC setting some kind of standard on the data, it wouldn’t be possible to integrate them.
> My working theory is that the language standardisation effort invented the latter. So when people say C was always like this, they mean since ansi c89, and there was no language before that. And when people say C used to be typed/convenient assembly language, they're referring to the language that was called C that existed in reality prior to that standards document.

But the committee has always had a lot of C compiler developers in it. The people who wrote the C89 standard were the same people who developed many of the C compilers in use before C89. The people who created the reality prior to C89 created the reality after C89. Any perception of "portable assembly" probably stemmed simply from the fact that optimizers were much less sophisticated.

I think what you are looking for a is "(pure) functional reactive programming".

The problem with caching is that it is very often highly individual and it usually comes with drawbacks, i.e. you win performance here but lose it there or you win performance but you lose consistency. (related: CAP theorem)
