Naming an externally linked function with the prefix "str" is by itself UB since that prefix is reserved for <string.h>.

Time for scientists to return to the Invisible College: a guild of science that keeps their research to themselves for the benefit of their own membership.

I was lamenting the other day that we used to have SGML SHORTREF, then XML came along because supposedly SGML is just too hard to parse. But XML is for computers, not for humans. So then we got Markdown, which is worse than where we started from.

Not that I'm disagreeing with your main point, but I will say that Toyota's hybrid design is one of the best ICE engines out there. The transmission is replaced with planetary gears and the starter and alternators are replaced with a pair of motors to control the throttle and continuously variable transmission, making it one of the gentlest engine designs out there.

But yes, there is engine oil to be replaced and whatnot.

And also, to your point, my experience with my PHEV is my short range driving is electric, but it turns out most of my miles is consumed by annual long range trips. If I commuted to work, things would tip more in favour of EV driving. All to say how much EV you get out of your PHEV will depend highly on the type of driving one does.

I'm pretty sure Carney is a Progressive Conservative.

I don't actually know anything, but I've been wondering lately: is higher house prices simply a consequence of Baumol's cost disease? If so, then there is kinda nothing we can do about it, right?. Higher house prices is simply a consequence of improved productivity elsewhere, and thus it is necessary to spend a larger fraction of one's income on housing.

I think the answer to the question “how do we stop technology X from destroying us?” lies in licensing and regulation enacted through legislation.

In the golden age of the 90's we were able to ban CFCs, but I'm skeptical we could do that today. We no longer have that political ability, and I doubt we will get it back any time soon.

When I'm trying to plug my PS/2 keyboard into the port in back of my computer which I cannot see, instead of needing to try two orientations, I need to try every orientation.

How does the arXiv manage the same feat for one tenth the cost?

Sure, I get that most humans aren't programmers, but the thrust of the article here is defending the position that "AI Can Write Your Code. [It Can’t Do Your Job.]" However, this task is literally the sort of code that I write. So if AI cannot do the above task, then AI cannot (yet) write my code.

I don't know what other programmers are doing, but a lot of my time is spent on tasks like this.

Here's another random task: Write an analytic ray - cubic Bézier patch intersection routine based on the based on the "Ray Tracing Parametric Patches", SIGGRAPH 82 paper. This is a task I did as part of my final project for my undergraduate graphics class.

These are both straightforward tasks to take well-described existing algorithms from literature and implement them concretely. Very few design choices to consider. In theory it ought to be right up the alley for what AI is supposedly good for.

Let me know when AI can create functions for the secp256k1 library that adds a point in jacobian coordinates to another point in jacobian coordinates, both in variable time and in constant time. i.e. add functions

    void secp256k1_gej_add_gej(secp256k1_gej *r, const secp256k1_gej *a, const secp256k1_gej *b);

    void secp256k1_gej_add_gej_var(secp256k1_gej *r, const secp256k1_gej *a, const secp256k1_gej *b);

I also unsubscribed, but even with you and me out, from what I read, it was a profitable move on Netflix's part. I guess I can't fault them.

Do not try this at home, but I replaced the lead acid battery in my UPS with a LFP battery. From what I read online, the charging curves for lead acid batteries and LFP batteries are very similar. The LFP batteries have a slightly higher charging voltage, so I expect my LFP battery to only charge upto about 80% capacity or so due to the charging voltage being slightly too low. I'm hoping the battery will last 10 years instead of 2 or 3 years.

Do not try this at home, as changing battery chemistry is quite ill advised.

I used my rooted TV to root my PS4. I'm not even joking.

Not that I'm qualified to reply, but I think this is debated. I seem to recall reading in "Immune" by Philipp Dettmer that there is an argument that a virus is analogous to a spore stage of life, and the virus begins "living" when it plants itself inside a cell full of "nutrients", sheds it's skin and begins consuming and replicating.

How does the implementation of unique types works? It seems you need to add some salt to the hashes of unique type data, but where does the entropy come from?

I've use archforms in my custom markup before: https://r6.ca/HtmlAsSgml.html

For example added an <nbsp> attribute to turn all spaces into non-breaking spaces, and used archforms to remove the attribute afterwards.

But yeah, maybe for Makrdown you don't need archforms. On the other hand, perhaps there is some super clever way to use archforms to get your reference links working.

How do you deal with "branded" types, if you know what I mean.

Edit: I mean structurally identical types that are meant to be distinct. As I recall Modula 3 used a BRANDED keyword for this.

I've been meaning to see how close I can come to Markdown syntax using SGML's SHORTREF and perhaps architectural forms.

How much is it down over the past 30 years?

FWIW, my mental CAD/USD price anchor was set when I was coming of age at 0.75 CAD / USD. Today it at 0.73 CAD / USD, and I've seen it touch 0.60 ish and pass parity in my lifetime.

Huh? The CAD/USD exchange rate is exactly where I remember it being 30 years ago.

I also have a ventless, but it is a washr/dryer all-in-one unit.

It probably also takes 4.5 hours to wash and dry, but I wouldn't know because it happens when I'm sleeping (which just happens to be the same time as the ultra-low time-of-day electricity rates where I live) . It's pretty great. Definitely recommend.

As someone not into electronics, can you explain how that works. I'm only familiar with transformers which, of course, require AC?

FWIW, I migrated to ed25519-sk SSH keys backed by FIDO2 credentials on my Yubikeys, and I really love it. The fact that my credentials effectively can never be lifted out of my hardware key is quite comforting.

This is the way.

Thanks for reminding me of CGP Grey's "This Video Will Make You Angry": https://youtu.be/rE3j_RHkqJc

Now I feel I should rewatch this video annually as a reminder to myself, or maybe monthly.

It's also a temporary anomaly as the moon has been moving and continues to move further away from the earth. See Lunar Recession.

I presume he is the same one who authored "Divine Proportions: Rational Trigonometry to Universal Geometry" (https://www.goodreads.com/book/show/791022.Divine_Proportion...) so I suspect he is not misquoted.

I actually quite liked "Divine Proportions". As far as I know Wildberger is eccentric, but not exactly a crackpot.
