if you work on a non-trivial c++ code base, being vigilant about compile times can literally make the difference between compiling your codebase from scratch in a minute vs. compiling it in an hour or more. 0% exaggeration here. With similar relative differences for incremental compiles. Nothing kills a code-base's hackability like waiting around to be able to actually run code you wrote.

Include code style is also just the tip of the iceberg. This also includes not using many c++ features that blow compile times up unless the gain from using them is so big that you eat the compile time (like containers would be an obvious example).
Wobbly tables and the intermediate value theorem
My examples are from boring enterprise, not from what we love to create at home. I’ve read and patched literally meters long queries in analytics, which could be reduced dramatically by being self-referential and by other approaches discussed itt. Of course these could be refactored into something “create view/temp/cte”, but that requires a full control of ddl, special access rights and code ownership. Most space was used by similar case-when-then constructs and permutations of values these produced. The original code was on official support, so we couldn’t just rewrite it, because migrating to the next update would cost a week instead of an hour.

I could reach to and post a lenghty example, but it’s nothing but boring reshuffles really, spiced with 3-level joins of “modelling db in db to allow user columns”.

I agree on the LTR idea, because reading a symbol not yet defined may lead to confusion.
But capital gains tax alone doesn't make the entire equation of risk vs reward, unless you're putting capital gains tax all the way to 100%. Even if it was 90%, if the risk was zero, the time investment was near zero and the reward was your assets going up by 4% post-tax, you'd bet people would still invest, regardless of income tax.
I've used VueFormulate in the past, and it was extremely powerful albeit somewhat bloated. FormKit seems like a step in the right direction. Good Luck!
>it is taxed less than wage income to encourage people to spend their money investing, rather than spending it in consumption.

Did you mean speculating? A few % of so-called investors are actually supporting new businesses. I believe it's obvious when you think about investing in crypto.
It's worth noting the "up to" part. Well maintained and cleaned chains are effective, but I would guess that a lot of commuter bikes have dirty, rusty, and worn chains that lose with a lot of efficiency. Couple that with poorly maintained and adjusted gears and alternatives might not be far off in efficiency if they're a closed system with less maintenance requirements.
It's a little strange that they went to the trouble to pixelate the real world device when there is a 3D render in the video as well. Hard to imagine what would be worth obscuring that way. Branding, perhaps?
> Our own brains have specialized areas

But Intelligence is one of those, and when people start calling naïvely calling "intelligence" its opposite "imprint", there is a problem. There are even the seeds of a social problem.

> orchestrating ... specialized models

Intelligence (ontology development) is one such specialized model which I have seen more faithfully and consciously attempted in classic AI as opposed to contemporary. Orchestration is crucial for the peripherals that allow the input/output. The study of "generalization" is none the less crucial, because we are to investigate the development of a system that can intrinsically, by its own nature, be exported to the largest number of relatable skills. Even with the highest specialization, up to physical, there is a matter of organicity: a hand is "specialized", yet a hook is not a hand.
I think the implication is that cowbird behaviours are genetically and/or epigenetically encoded.
Anyone else laughing maniacally? I am. This is so great. Tesla is tanking. Twitter is, too (and so is the market in general but if the Twitter deal were a sure thing it’d be trading at near 54.20 but it’s not…). I think the market is finally figuring out that Musk is a smart guy with no filter and says anything he wants to because he was given a platform because Tesla’s stock has 10x’d.

> For example, some hiring technologies try to predict who will be a good employee by comparing applicants to current successful employees. Because people with disabilities have historically been excluded from many jobs and may not be a part of the employer’s current staff, this may result in discrimination.

> For example, if a county government uses facial and voice analysis technologies to evaluate applicants’ skills and abilities, people with disabilities like autism or speech impairments may be screened out, even if they are qualified for the job.

> For example, an applicant to a school district with a vision impairment may get passed over for a staff assistant job because they do poorly on a computer-based test that requires them to see, even though that applicant is able to do the job.

> For example, if a city government uses an online interview program that does not work with a blind applicant’s computer screen-reader program, the government must provide a reasonable accommodation for the interview, such as an accessible version of the program, unless it would create an undue hardship for the city government.

I don't follow any such rules for my own codebase and here are how my compilation times look like for three representative files: https://streamable.com/pboot1

- first and second one have tons of Qt / std / boost:: / etc... stuff

- third one includes opencv.hpp (which includes most opencv libraries)

I have a hard time seeing the benefit of putting more effort in this considering that the edit -> build -> run cycles takes around a second or two in all cases, and I don't even use all the clang PCH options available in recent clang versions.

So no,

I use a vue dev server daily (both with webpack previously and now with the way faster vite) and it's pretty much instant.

These projects only recompile the code that changes, then via chunking the browser only reloads a tiny specific .js file that contained that one component matching the vue-route, so usually 10-30kb refresh (and it loads about ~10x small .js files per page), which happens before I can tab back or notice when widescreened.

Previously when I used the slower Webpack without chunking it started to take time when the project grew large. But that was long ago (3 years ago?).

Playing devil’s advocate here: if this graphical interface could be manipulated without mouse clicks, you’re still interested? Alternatively: if there were some high bandwidth, low latency feedback loop between you and this app, an order of magnitude faster than how you currently iterate on working with React, you’d consider it?
That's an interesting take. Do you have some sources you could share to support your claim?
There is something wrong instigating further extreme resource exhaustion to serve boyish Star Trek pipe dreams.

I think in most (West-) European countries there are strict regulations/requirements that require ducts/pipes for any kind of power line. When my house was built (35 years ago) there were already regulations in place that required separate ducts for each group, separate groups for wet rooms (kitchen, bathroom) with grounding, etc.

Overall I found the standards of electrical work in Europe is significantly higher than US counterparts. In modern buildings every outlet and line has mandatory grounding, and GFCI is built into the fuse box on every power line for any building that's less than 30 years old. That really came in handy once when I accidentally hit a power line when drilling through the ceiling. I can't imagine doing any kind of renovation work without GFCI on everything.

I believe the 3:1 metric is to be taken literally with equally skilled/equipped forces (source: was in the military). The Ukrainian military is outperforming the Russian military and the Ukrainians have a ton of equipment the Russians weren't anticipating, so the 3:1 metric isn't working out so well.
> I've been fascinated by this style ever since I saw the "J Incunabulum." Unfortunately, it seems to come from idol worship.

Is that true?

Isn't this style just a natural place to arrive after agreeing with and understanding "Notation as a tool of thought"?

Also while learning J/K I didn't notice much of this worship.

I'm afraid of writing off a purposely chosen style as one that has no merits and is explained by idol worship.

Hi s1mon, thanks for your feedback.

I'd say I have two customer groups in mind:

1. Technologically open-minded people who have a bit of money and want an e-paper calendar in their office or for their family. They can buy my e paper screen and set it up with the mobile app in 2 minutes.

2. Developers who want to build their own e-paper application and need a platform to build it on. They can buy my device and use the image-url feature to display their own designs.

It's funny because their argument for pushing crypto is that govt is bad, taxation is theft, so govt needs to be circumvented financially in favor of a libertarian utopia with zero taxes so that govt can be crippled. Why would you want to take help from something you think is a terrible influence on the world? It comes off as selfish, capitalism and tax avoidance and even evasion when it suits you and socialism when you need help.
> Could most checklists used by pilots be automated?

A machine would be a black box, and there is room for error. A human can use reason and proper judgement to avoid error, although they're not immune from error, but I'd rather a human making decisions when flying. Either that, or use a drone which has a remote operator, so if the drone does crash: there's no human casualty.
It's a particular kind of intelligence. I'm actually in a relationship with somebody who tends to lean this direction. If you know what you're dealing with it's not too burdensome.

What's happening is, you have a person (Elon) of exceptional intelligence, so they can recognize a thing or concept and instantly follow it out to rational conclusions faster than the people around them, but they have not developed their intuitive side and don't respect the empty part, the unknown part, of the problem space.

It's like that halting problem thing: they become so accustomed to being able to see 'the answer' that they get blind to the mystery, the ambiguity of the non-answers and the areas where a real innovation will come from. They're not surprised by anything, or surprisable, so they become a specific kind of intelligent, very very quick and correct.

If you're a designer/inventor/artist type person you rely much more heavily on the non-answer spaces because those are where you work. That's not Elon. He has people for that, and takes the credit for their work, and impresses them so much with his ability to be quick that they go right along with it. In real terms they could not get their stuff done without him as that ringleader, figurehead, the 'Mr. Outside' there to impress the masses and get them to give him their money. It's a symbiotic relationship and Elon has done that over and over.

Don't look to Elon personally to have the revolutionary idea. However, if you show him one, he may well see where it leads way quicker than you do… and take it, and make a business out of it, and then hire you and have you doing it whilst taking a big cut of what you earn from it.

In this way Elon 'gets' capitalism as well and quickly as he gets everything else. He's definitely the man for late stage capitalism.
He does not look indecisive :), to the contrary seems to be jumping to action without bothering much about consequences. For example, why make acquisition bid without checking on spam accounts first? IIRC his offer letter to the Twitter did not carry this condition about spam bots.

I'm not quite sure what sort of mental model one must have to pose such a question (maybe some sort of reincarnation-like spirituality where all animals and humans have the same soul/spirit substance that after birth has to figure out what kind of animal it was slotted into this time?).

How does a rock know to be a rock? Why doesn't it get confused and become water?

A cat doesn't need to know that it "is a cat". It just has a cat brain and a cat body, so it does cat stuff.

Of course, there is some learned behavior, parental socialization and some "culture"-like practices is certain species, but it's not like cats may forget "how to cat". Do you think a fish may get confused and suddenly forget to be a fish and instead act like a mouse?
I disagree; you were dealing with a difficult personality, as a young child. Ridiculous to shame you over that.
I think you're confusing art with technique.

The human drawn ones were much more interesting to look at, as art, usually because of the emotion and hints of narrative conveyed by facial expressions. I also liked the giant cat.

These days famous artists often don't execute the artwork themselves, they leave that to craftspeople. They have the idea, and the fame to imbue it with attention which connects it with the semantic fabric of the current art scene.
My theory is that he is actually just acting like the deal won't close. The plans they put in place after the activist shareholder have largely failed and now the market conditions are way worse. So he's going to bring in some new people and make a big pivot to some other revenue streams. I don't know what that is yet, but I think that'll emerge over the next 6-12 months.
Ah, middle class.

"Being polite" is emotional labor, whether or not that labor takes the form of "masking" a disability. While of course we should be respectful of those we engage with, avoidance of emotional labor should always take precedence over shallow notions of politeness that have nothing to do with actual respect for others.

Probably because you are conflating Infrastructure as code with Infrastructure from code.
> As I post in the comments below, we now have WASM, so C++ and Rust can all run in browsers. This can provide a near-native audio performance.

Native audio apps require realtime scheduling and memory locking, things you cannot do/control in the browser.

The problem is that you can likely get 70-85% of "it" done in the browser, but when the user/performer need the remaining 15-30% for whatever reason, what do they do then?

I spent years of my life on the problem of generating useful multi-platform code from a GUI tool and integrating it into designer and developer workflows. Before giving up I made React Studio (https://reactstudio.com) which is owned by my co-founders now.

It's insanely difficult. Nobody's needs are exactly the same, and nobody can agree even on the basics of how a web app is structured: where does CSS go, how do you update your global data, etc.

The abstractions I had to build to handle that then increased the learning curve to such levels that it became more like a CAD tool where you'd practically need to train teams into a new way of thinking for them to become productive. Having traction with a few customers never seemed to translate into something scalable. (Maybe with an actual sales team an enterprise strategy could have worked.)

My original version of the product was a mobile-only UI tool that generated native code for iOS and Android. In retrospect that was a better product than trying to expand into full-blown web apps. In native, a button is a button and a tab bar is a tab bar (with small differences between UIKit and Android); in web anything can be anything, and it's a point of pride to reinvent the basics constantly, so a tool must somehow adapt to the shifting tides of how CSS must look this year.
I guess you can run a sting operation, it may work.
YMMV, but I got completely used to a mask after a couple of nights.
It's not linear. Cutting 1% of costs while maintaining the same revenue might be trivial. Cutting 10% of costs might be very doable. Cutting 50% of costs might be incredibly hard.

And I assure you that growing revenue by 100% is far easier than cutting costs by 100% (while maintaining current revenue).

Also, there's a human element to it. I'd venture that most CEOs would much rather the company make more money than have to lower bonuses and benefits, cut down of office space and fire employees.
What makes you think that is the likely outcome?
While the internet may feel like a public park, when you access twitter's API you are connecting to their servers, which are not owned by the state. They are owned by a private entity.

Private entities can make whatever rules they want for their property as long as those rules don't break laws.

Twitter says don't reverse engineer. You reverse engineer. They block you. They can do that. If you actually break a law and cause damages with your reverse engineering, they can consider suing you. They can do that too.

If you are ignorant to the terms in which someone is offering a service to you then you are only exposing yourself to unneeded risk.
not this time though
Of those three, "networking" and "thought leadership" are more hobbies rather than concrete responsibilities of the job.

There are actual concrete responsibilities that a CEO at that level needs to accomplish, a sample of which include:

- fundraising

- organizational structuring

- hiring

- strategic planning + competitive positioning

- go to market motions

- R&D

- investor relations

There's nothing fungible about any of these responsibilities, so no matter how many ordinary people you stack together, you'll never arrive at even a fraction of what a competent executive can do. Companies have executives for the same reasons countries do.

Executives rotate in and out of power subject to the ongoing favor of their stakeholders, but the hierarchical structure of retaining an executive to represent the will of those stakeholders remains in place because there's no efficient way to operate otherwise.
I suspect the thing is that, sure, there's a reasonable chance you're innocuous enough.

But say, in an unrelated incident, a kid had gone missing, and beforehand there was a suspicious stranger with no attachment to any of the kids watching them from outside the grounds. It later turns out the person was watching them to identify a target to kidnap.

Then say the school did nothing because "they're allowed", on the basis of everything described. But now a child is missing and the school didn't act on an obvious potential red flag. Would the parents find that acceptable? No. Would politicians and their voters find that acceptable? Probably not. Heads would roll.

Ultimately the school is managing its risk level by taking action in that situation.
He has multiple examples of using censorship himself to protect his companies. He denied a reviewer access to their vehicle, has stifled the speech of former employees of his companies, and has tried to silence a dissenter publishing publicly available data of his plane. You've fallen for the hype; Elon merely dresses himself in the flag of a free speech absolutist. He is exactly like the establishment in this regard: speech for me, but not for thee.
I would like to have a bike with this drive system for doing structured training workouts outdoors. Cyclists and triathletes often do workouts involving multiple steps with a prescribed power output, for example 10 one minute intervals at 300 W with two minutes of recovery at 140 W plus 15 minutes of warm up and cool down at 170 W. It's simple to execute that workout on an indoor smart trainer in erg mode since it will dynamically adjust the resistance to hit the exact target power, but even with a game like Zwift indoor training is super boring. You can do the same workout outdoors on a real bike, but then you have to keep watching the power meter to stay in the target range which is distracting and somewhat of a safety hazard. So this system could offer the best of both worlds if the target power is externally controllable through ANT+. Of course that would probably be only a small niche market.
