> The former is because meaningfully using smart pointers (i.e. letting them handle destruction) inside an allocator aware data structure (as many C++ data structures tend to be, and even data structures in Rust) would require duplicating the allocator over and over.

Not quite clear what duplicating means here, but in general most smart_pointers can be constructed with an optional "deleter". Well implmented this would results into the addition one reference (64 bits) field to each instance of the smart_pointer (remove that by using some static member kung-fu but this is hardly worth it).

> The latter is because compilers do not perform TCO in many real world examples (and certainly not in debug mode); if you write a linked list using `std::unique_ptr` the destructor will blow your stack.

This true for all deeply nested structure. Same thing happen in reference counted system like swift.
One can mitigate this by simply controlling the order of destruction.

If you need to perform real time messaging between two servers use either RPC or WebSockets. These are bidirectional messaging in binary without a round trip or large plain text header. What the data is, where it comes from, or how its generated is completely irrelevant to the transmission.

I have a Node.js app written specifically for this scenario. You can try my app to see if it solves for your use case. It is designed right now to support file system streaming, text messaging, status messaging, and so forth. It can be supported to messaging anything you need. Remote instruction execution will require more effort for security reasons.

Tech Flashback: Generic Light-Up Mobile Phone Keyring
That sounds, to my utterly unprofessional ass, like an astigmatism? Basically your eye is deformed slightly like a football, giving your prescription a strength, cyclical value (a cylindrical bias to the lens, as I understand it) and a rotation of that cylindrical bias for the eye.

It does require small stores to order them custom (larger stores can often grind them in-house), but $600 seems... off. Perhaps if it's a high refraction material (thinner lenses) with all the various coatings?

The nice thing is if you have your prescription, you can order glasses from anywhere (including online), your prescription is not tied to one provider.

> As a practical matter, many of my college classes went too quickly to do anything _but_ teach the solution

My calculus instructor in college was one of those where they'd go through the problem and on step 7 (or whatever) go "Oh, where did we make the error?" where we'd all flail until they pointed us back to step 3 and then had to redo everything all over again. It was, for me, the most maddening way to teach. I was struggling just to get everything copied from the board to experience it by rote, completely unprepared to even process what was going on, much less have to go back and redo everything all over again.

I dropped that class. I always felt it was a mistake not taking calculus in High School. I had a very good relationship with the math teacher there, and we could have done it, to some level, casually between classes. I just didn't take him up on it.

I've never learned calculus.

Never trust a mathematician wrt trivial | left as an exercise to the reader :

"One day Shizuo Kakutani was teaching a class at Yale. He wrote down a lemma on the blackboard and announced that the proof was obvious. One student timidly raised his hand and said that it wasn't obvious to him. Could Kakutani explain?

After several moments' thought, Kakutani realized that he could not himself prove the lemma. He apologized, and said that he would report back at their next class meeting.

After class, Kakutani, went straight to his office. He labored for quite a time and found that he could not prove the pesky lemma. He skipped lunch and went to the library to track down the lemma. After much work, he finally found the original paper. The lemma was stated clearly and succinctly. For the proof, the author had written, 'Exercise for the reader.'

The author of this 1941 paper was Kakutani."

To basically +1 the sibling comment, you likely have astigmatism. $600 is pretty high but lenses are quite a bit more expensive than standard spherical lenses.

It is incredibly common, but essentially your eye is elongated in one axis meaning that your lenses need to correct differently in each axis. It also means that despite having a low prescription, you may have focus issues across the spectrum of depth.
Depending on where you place the line between a state machine and a CPU, my 16-bit system might actually be the CPU with the lowest amount of ICs.

Comparisons like this have always seemed a bit unnatural, since you can get an entire x86 PC on a single chip, and things like calculators, cheap media players, and various toys also use nothing more than one COB.

Also, I'd say that this machine also nicely demonstrates that a CPU is a state machine - a rather large one.
And you can have the same for a similar price in the States. The US cellular market is quite good. Have a look at Canada if you want to see what a cartel looks like.

In BB model, CMB emitted by hot plasma. Where it is, that plasma?

In steady universe model, CMB is light with z=1000, emitted by distant galaxies, in range of 4Tly. It explains high uniformity of temperature. It's like the temperature of a water stream from underground: it's uniform across a climate area because underground temperature averages seasonal temperature shifting.
From first look, yes, and for more or less modern engines, which really don't need lead.

But for planes, normal age more than 20 years, even exist workhorses with 70 years.

They have very old engine technologies, some literally spread gas on ground (use lead in it to lubricate valves, which are outside, like on old star engines).
So even when you walking where such plane was, you will gather some lead.

I bought some Zenni Optical glasses recently. Paid for the blue light filter ("Blokz"), and the yellow and amber clip-ons.

Night Driving Clip-On (Yellow Tint) - $5.95. Sunglasses Clip-On - Amber - $3.95

They also came with a "Blue Light Laser Pen".

The lenses do block the narrow wavelength of the "blue light laser".

High-energy photons - violet -> Blue - are a full 100nm: https://en.wikipedia.org/wiki/Visible_spectrum#Spectral_colo...

It's not enough to block out a few random wavelengths of blue, you need to reduce them all.

One of you told about using amber glasses to protect themselves from LED streetlights. I found that amber glasses blocked out too much light. Some yellow glasses are pretty good, some yellow glasses are worthless. These are my new favorite blue-blockers: https://www.harborfreight.com/safety/vision-protection/safet...

They work great with contacts. I can also put my glasses over them. They're not as good as the Cocoons, that my local glasses store stopped selling because people were wearing them at night, but they can't be beat for the price.

My comment from 1.5 years ago: https://news.ycombinator.com/item?id=29962021 "Most of the glasses sold for blue-light blocking don't block nearly enough of the blue light to make a meaningful difference. I think the main thing is to reduce the amount of blue light that you're exposed to at night. [...]"

Mint is arguably the most refined Debian variant at this time.

I used Ubuntu for many years but got tired of fighting with obnoxious snaps that I didn't ask for.

Mint doesn't use them, but supports flatpack instead. Not only that, but if you don't use them, you need not know they exist—unlike snaps.

Fedora on the other hand is fine. Although ultimately plays into the hand of Blue Hat, keep that in mind.
I came up with a variant of this that extends the motion vector into “matter” dimensions. Then the logical consequence is that the more matter you have, the less of the unit vector is available for movement in time == time dilation due to mass.

Similarly, only vectors with zero length in the matter direction can have unit length in the space/time direction. This is the “only massless particles move at the speed of light” rule.

RE delegating frontend work, it’s a valid concern. Might be worth it to see how much of the Django templating work you could have the FE developers do; you can often still split it so that they do the presentation work. (Great thing about Django/HTMX is you still work with HTML generated in template fragments). The “API” is instead the state that you push into the template context. It’s a really productive development loop.

On 2b, yep exactly as you say. Instead of updating arbitrary fields with PUT/PATCH, you would have an endpoint per action. (Or a mix of both approaches if it is more expedient).

This doesn’t make much sense for “data bag” objects with lots of potential fields to edit like a user’s profile. But say your object has a mutation that always takes one parameter to update a model with many other incidental fields, you can map that to a POST /obj/<id>/update_foo {param} which is basically an RPC mapping to a single function.

This makes most sense when you have objects that look like FSMs since in that case you might have a few transitions, each taking different args, and each dependent on a specific state as precondition. But I have used this for e.g.“users/<id>/activate” which updates the status, sets a updated_at timestamp, and cannot be undone. The alternative is something like PATCH the is_active field, and having some gnarly logic to handle bookkeeping around time stamps and preventing reverting.

Another way of thinking about it is if any combination of values is valid, it doesn’t help. But as soon as you need to handle state transitions and particularly when you have multiple, then simply updating raw fields results in extremely messy validation logic within your update endpoint.

It seems like we're in a sort of 'autodidacticism boom'. I see this so much in almost everything now--physics, math, MIT courses online, etc. I think this is symptomatic of how people have lost faith in institutions--be it colleges, schools, govt, etc.--and see the DIY route as being better, or maybe schools are doing a poor job teaching or costs are too high, such as tuition. But why the sudden, huge interest in DIY math and physics especially? I dunno.

Do you mean prismatic lenses? I had awful headaches at one point and the optician added prism to my prescription, I don't think the cost changed at all (UK optician).

I believe prismatic lenses are normally used to correct muscle weakness which may cause eye strain (and double vision in severe cases). My prescription was changed back to no prism after a few years.
