I don't know that it is -- electric scooters are controversial -- some folks want them on sidewalks; others in bike lines; yet others only in mixed traffic with cars.
I'd opt for a simpler and less precise name like "Sort by Rating", but then offer the more precise definition via a tooltip or something, to minimize complexity for the typical user but ensure that accurate information is available for those who are interested.
Is that really a fatal flaw? It's humans reading the ratings, and humans doing the ratings, so our human-factors might balance out a bit. I don't think people come in expecting the rating system to be perfectly linear because we have a mental model of how other humans rate things -- 1 star and 5 stars are very common, even when there's obviously ways the thing could be worse/better. So even though 3 stars sounds like more than 50%, most people would consider 3.0 stars a very poor rating.
I agree with you here, but I don't agree on downplaying complex numbers to be just a base vector and orthogonal.

If we take a matrix representation of a complex number it is usually done as a 2x2 matrix of very specific structure. I completely agree that it is easier to work with. But looking at them this way misses very important place of them in the grand scheme of things.

Complex numbers are actually what real numbers really ARE under the hood, we just aren't taught to think this way. 'i' is what real numbers miss to be completed. And you don't need 'j's, 'k's and others.

If your point is that introducing 'i' above traditional real numbers syntax is ugly - I completely agree.
Stalin attempted to assassinate Tito.

Tito and Stalin didn't see eye-to-eye. There was complete split after the WWII. Soviets blockaded Yugoslavia and Yugoslavia was included in Truman's Mutual Defense Assistance Program and received military aid.
>we should certainly work on making cities more appealing so that people will make more sustainable choices.

I think there's definitely a percentage of humans who are just hard-wired not to live in cities. I for one can't stand urban living, I'd be a depressed alcoholic within months of moving to a place like London I think. Don't get me wrong I'm not one of those "I hate cities and everyone who lives in them" sorts, I visit cities fairly often and appreciate their qualities but after a while I literally start tasting the air and feel gross for it. There's nothing that could make dense living in a concrete environment appealing to me long-term, and I think there's a bit of a presumptious attitude in some parts of this discussion* that we can just coerce, gaslight, or "nudge" people until they're mentally ground down enough to grudgingly live in a city. Personally I'd emmigrate long before we reached this point - I've had enough "nudges" for a lifetime over the last two years!

Remote working has been a real blessing for me, and hopefully things like Starlink will be even better for people who fall into the "knowledge workers who instinctively dislike urban life" category. I also recognise that this is an enormous privilege though, most of society isn't in a position to take advantage of these things and there's all sorts of issues caused by people moving to less well-off areas and driving up house prices and other services out of the reach of people who've lived their lives there. I'm not sure what the solution is really, but I definitely think there's shades of grey.

I find the e-bike that the article talks about (S-pedelec) to be the peak of unsafeness for two wheeled vehicles. A colleague had one and let me try it - I quickly noped out.

He's doing 40mph in traffic with his bike shorts and a flimsy helmet. The power to weight ratio also gives him enormous acceleration, so he can jump from the red lights in front of everyone. Other drivers often misjudge how quickly he can move and he had some close calls like this.

If I were the author I would reconsider using one of these, especially with his history of accidents...

Whole Foods have Amazon lockers. They must have some system for dealing with unclaimed items.
The end of the gif with the distances between the sun, Mercury, Venus and Earth to scale is kind of informative and then you look at the fine print that indicates that with that scale the planets are all represented at 50x and the sun at 2x and it really makes the distances that much more amazingly large. And I have to confess that my mental image of the distance from Mercury to the sun was way off—I'd always envisioned it as being close enough that the sun would fill the daytime sky but really it would just look about 2.5–3 times bigger than it does on Earth.
UAP sightings are rarely taken seriously, which is no surprise considering that 99% don't hold up against any kind of scrutiny. There are however a number of credible sightings, the 2004 USS Nimitz incident being the most well known. Unfortunately, studying UAPs in an academic context is still mostly career suicide, so exploratory and speculative work like uaptheory.com can only be found at the fringes. As physicist Avi Loeb said before: if we don't look, we will never find anything. If only we could take the topic more seriously, we may eventually find that the Fermi Paradox is not a paradox after all.
there are people who aren't capable of this due to neuro-divergence. folks with ADD and ADHD affected by RSD wouldn't be able to do what you're asking, and thus these laws are intended to help those who cannot help themselves, not the people not currently being affected.
That is quite interesting. But...is it me or is that a _very_ exaggerated description?
I can attest that so far the lifetime static analysers for C++ haven't progressed that much.

However until certain C++ overloads don't give more love to memory-safe, garbage collected language or languages like Rust, that is better than nothing.

For example, I don't expect Windows team to ever lose their love for C++, NVidia moving from their C++ love for CUDA, or Metal shaders in something else.

Ah, and then many of those languages are keeping C++ around by building on top of GCC or LLVM.

So any improvement towards to make C and C++ safer is better than just using them as they are.
I think this is the key here: conceptually, there may be some cognitive shear around the word "plane." In the near-term VTOLs aren't going to be airliners or, for that matter, flying cars. Cessnas and helicopters, though...

Never considered fast-math. I get the sense its useful but can create awkward and/or unexpected surprises. If I was to use it I'd have to have a verification test harness as part of some pipeline to comfirm no weirdness. Literally a bunch of example canary calculations to determine if fast-math will kill or harm some real use case.

Is this a sensible approach? What are others experiences around this? I've never bothered with this kind of optimisation and I now vaguely feel like I'm missing out.

I tend to use calculations for deterministic purposes rather than pure accuracy. 1+1=2.1 where the answer is stable and approximate is still better and more useful than 1+1=2.0 but where the answer is unstable. Eg because one of those is 0.9999999 and the precision triggers some edge case.

Britain was the first country to industrialise, it'd be surprising if it wasn't so low.
4000 W? That sounds a little excessive :)

A typical s-pedelec is somewhere between 350 and 750 W nominal and with peaks of maybe twice that.
If you're exerting yourself you tend to pay attention to what's happening around you. I noticed that folks that go very fast on their two-wheeled vehicle without too much effort get distracted quite easily.
The containers won't run on an M1 Macs.

Maybe what we need here is an extension where you can filter out articles?

It adds a click event to each link for the article, and then after a day has passed, will start filtering that link out from HN results? I give it a gap of a day because maybe you'd want to return and leave a comment.

I might try my hand at a greasemonkey script if you're interested.

Though, personally, I have no great issue seeing high quality posts again occasionally.
In my fantasy/scifi book series I have it such that aliens can make it to Earth, but why do they want to? The few who do, they are doing it for scientific/exploration purposes and therefore not interested in breaking our ignorance.

The break point is obviously aliens taking refuge in our system hiding from their enemy. We now know aliens for sure exist, they just find us boring. They'd rather goto vacation/pleasure stations, not some jerk primitive planet who attack all aliens they meet.
The complex numbers are 2-dimensional, but their 2 dimensions are not the 2 dimensions of a normal 2-dimensional geometric plane, they are 2 other dimensions.

The 2 dimensions of a geometric plane correspond to the 2 orthogonal translations of the plane.

The 2 dimensions of a complex number do not correspond to translations, but to scalings and rotations of the geometric plane.

The multiplication of the complex numbers corresponds to the composition of scalings and plane rotations, which are invertible operations and that is why the set of complex numbers is a commutative field, unlike the set of points of a geometric plane, which does not have such an algebraic structure.

The set of complex numbers can be viewed as a plane, but it must be kept in mind that this plane is a distinct entity from a geometric plane.

(The Cartesian product of a geometric plane with a complex plane forms a geometric algebra with 4 dimensions.)
The the unseen ones are mostly the harmless ones. The grabby (basically the "expansionist Dyson sphere builders") are the ones we should be on the lookout for.

Robin Hanson's model explains the data, answers the Fermi paradox. We don't see aliens because if there were aliens to be seen they would be in our place. (Because the hard-steps model parametrized by habitable zone time-frames limited by the lifecycle of stars gives a distribution of emergence of intelligent life. And if just a few of those start expanding, they'll soon cover enormous volumes, taking away the possibility for later emergence of intelligent life.)

> I mean seriously, is this a real argument.

Yes, it's a real argument against "There isn't a single redeeming quality about Cryptocurrency". I agree that not everything with cryptocurrency is good. In fact, I'd argue most uses today are bad, and only a few are good.

But I haven't argued for that everything about cryptocurrencies are good.

Remember; "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."
I worked on an e-commerce site that attempted to solve the issue by simply not giving an average rating to an item until it had a certain amount of reviews. We still showed the reviews and their scores, but there was no top level average until it had enough reviews. We spent a lot of time in user testing and with surveys trying to figure it how to effectively communicate that.
Well, they may have had more information, but it certainly wasn't good information.
MIT also switched from Scheme to Python for undergraduate CS programming courses. They did it for the libraries and ease of use.

Nah, it's a rather basic problem and the solution is well known: do another LoadLibrary on the already loaded library. Of course, then you need a Free­Library­AndExit­Thread... [0] And the posts following [0] (you can see them at the bottom of the page in the "Read Next" section) explain more of the context.

All this stuff is there because of the built-in threading support in COM which, arguably, was pretty convoluted for some rather strange reasons ― what's the point of such precise RAII-ing of the DLLs? I guess the address space was really precious back then or something.

My experience is that one-off human costs tend to be extreme for exceptions at big organizations.

Handling exceptions might require a business day or two of admin time just to handle the baseline exception. Multiply 16 hours by salary, and you're at big bucks.

Plus, you need processes for oversight. That costs /a lot/ more. Ownership sounds great on paper -- where any support rep can grant an exception -- but in practice, that gradually leads to a culture of abuse. It starts little, and once that's part of the culture, increases over time.
I recently have been considering whether space travel is even relevant to advanced species.

Assuming the technological knowhow for interstellar travel requires much more evolution and adaptation I wonder if at that point we or any species would be interested in physically travelling.

Early scientific research was mostly based on field observations due to the lack of intricate technological understanding. As we advance, more and more of our research is done in labs and on computers for obvious reasons. I doubt aliens or our future selves will be reliant on field observations for research.

The ocean is on our doorstep, yet vast amounts of research have not gone into exploring that compared to space. The reason is because of the perceived potential outcomes of space vs ocean exploration. The same reasons will stop us from exploring physical space in the future, and could be preventing aliens from exploring now.

Eventually a matrix like integration with technology could give ourselves access to realities with enough to keep our minds occupied. Not only could we have access to procedurally generated worlds, but procedurally generated physics and rules to those worlds. Once we crack the locks to access the rules our consciousness we can generate even more "realities" to explore. Natural evolution of the mind could negate the need for the technological matrix.

I consider the mind to be the end game for exploration. The "last frontier" if you will. Negating the need for physical travel. Consider as an example the Organian way of life from Star Trek.
Accessing the code part and modifying during execution is actually rather easy in R.
Functions such as substitute or quote are commonly used and a language expression in R is a list that you can edit and evaluate back.

The internals itself in R actually sound quite lispy: both values and codes are SEXP (S-expressions).

R is inspired by Scheme and Common Lisp; it has first-class functions, multiple dispatch.

https://www.stat.auckland.ac.nz/~ihaka/downloads/Interface98...

"This decision, more than anything else, has driven the direction that R development has taken. As noted above, there are quite strong similarities between Scheme and S, and the adoption of the S syntax for our interpreter produced something which “felt” remarkably close to S."
Hey! I'm actually really interested to work on a personal project along this front. About a year back I organzied some files from research into a massive repository and I'd like to build a search engine to make it easier to query.

I remember a teacher who said (when I was a student) something like "if you care about precision use double". Now that I'm teaching, I force students to only use single-precision "float"s in their code, with the message that FP precision is a finite resource, and you don't learn how to manage any resource by increasing its supply. I think my students hate me.
Yes, I agree. But the question has become too political for dispassionate consideration, I guess.
I don't, and most don't either: there is no room. We have hot pipes through which hot water is pumped. At best, the high-rise itself has a hot water heater, but even that probably only holds a few hours worth of water. Serious storage is only there at the neighborhood level.
Trying to exceed the 32 km/h limit on my ebike is similar. It's like hitting a brick wall when the assist drops out.

I assume it's a combination of the extra weight and the extra losses from pedalling the motor as well as the wheels (mostly the second part I think). Going faster on my non-electric mountain bike is significantly easier.
https://archive.md/P4ELN
It's weird that they post these updates in PST. How is that relevant compared to posting UTC?
A lower speed for throttle-only sounds like a good solution!

To clarify, my original post was about non-electric bicycles, but my experience with pedal-assist ebikes [Jump (RIP) and Citibike/Baywheels] was that they were noticeably heavy and after a few blocks of pedaling really hard, I'd tire out and slow down. Perhaps you're gifted with a very high vo2max?
What do you mean by inability to do anything with a literal? You can capture it, turn into a variable, turn it into a "lambda" (make next, break, return local), use it like callbacks are used in any other language. Blocks are a bit special in that they go in their own slot for message sends (method calls) which allows the syntax to be unambiguous and the yield keyword allows for optimized calls to passed in blocks because methods that don't reference a block as data don't have to worry about the block outliving the stack frame.
Do EB-5 investor visas work well in practice for those looking to start a business in the US? Looking at the rules it would appear to be straightforward as long as you have the capital -invest $1.8M and employ 10 people. It there a catch other than the amount of the investment that makes it hard in practice?
Yes, it was mentioned in the post: you normally get prompted not just when there's a breakpoint, but when your code calls something that doesn't yet exist, for example, or try to access a non-defined variable [1]... you have the option to "fix" the issue and continue from the same point, continue with a different value, or just let it crash... and there's stuff like profiling and de-compiling [2] which are all available directly from the REPL as well.

It really isn’t and I suggest you give clojure an honest try to see why. It’s really hard to explain.
I wouldn't do it exactly this way, but for a CPU implementation I would consider a blocked rotate that decomposes the image into square tiles of about [cache-line x cache-line] in size (e.g., 8x8 for RGBA8 data with a 32 byte cache line). Then cycle sets of four tiles and rotate within them in the process. E.g., cycle and rotate the four A tiles, cycle and rotate the four B tiles, etc:

A B C D M I E A
E F G H N J F B
I J K L O K G C
M N O P P L H D
D H L P P O N M
C G K O L K J I
B F J N H G F E
A E I M D C B A

With the right tile sizes and memory alignment you could parallelize these steps without false sharing.
Power assist cuts out at different points, depending on design choice (and jurisdiction). Norwegian e-bikes, for instance, disconnect their power assist above 25kph and you need to pedal like crazy to go significantly faster than that.
