Ford sold a couple of million Model Ts (and gave up on his electric car project with Edison) before offering an electric starter motor as an option. The advantage of ICEs at the time was massive even if you had to hand crank the engine.

Yes, but once you have DC your losses will be less.
Its a little overambitious to compare electrical efficiency and heat cycle efficiency. Electrical efficiency says nothing about how that energy was generated; if it was generated in coal, gas turbine, nuclear etc then you simply cant exceed carnot efficiency (solar is far less efficient than that for how much energy hits the panel); it also doesnt say anything about the extractable specific energy, which far favors ICE vehicles, efficiency be damned, ice will run longer on a fixed weight of fuel than an EV will on the same weight battery.

EVs in my experience have been a step change in car tech. Having a battery as a starting point rather than an alternator opens so many doors, from just having a stable grid to run devices on, the real time AI video processing, to the ability to play modern games on the cars hardware. The designs are far more simple than ICE, take the steering wheel off a tesla vs an ICE and you can get a peak at just how far behind ICE is in relying on complicated and expensive implementations of basic functions.

I just don't like these comparisons regarding efficiency, we arent really making a fair comparison; if we did EVs would probably lose considering the energy source and transmission losses, and it still would be a useless metric because thats not what anyone (sane minded) has ever bought a car for. All I care about is that the cost of ownership makes sense; the fact that the total efficiency of my own setup, where solar charges my car, is probably <25%, does not concern me.
The issue most javascript frameworks try to fix with the DOM is the fact that it is not a language and does not have very good templating support. (Even web components in their plain form are pretty bad; no one wants to write document.appendChild everywhere)

But no one has dethroned HTML and CSS as a fully baked cross platform engine, because it has been battle tested and optimized to death. And not really for lack of trying; UI is just actually very complicated.

Great article, I’ve had the fun of implementing TTF rendering and this piece hits all the memorable points.

One nit, the comparison to Mach-O is anachronistic as TrueType was developed in the late 1980s, while Apple didn’t acquire NeXT until 1996.

No one mentioned magic. Frameworks are designed to do what PHP developers wind up implementing in an ad-hoc, haphazard way themselves, and tend to be better at doing it on average. Any code can have security issues but I'd trust a battle-hardened open source PHP framework over some random coder's hubris any day of the week.
Thank you. It looks like there is still a lot of work to do.
While I absolutely love his videos, with this one he lost me. It’s very technical, doesn’t serve a bigger purpose apart from maybe “look at how much you can do with so little” (it’s literally just about the pinball machine), and it’s very long.

My favourite videos are about washing machines, electrical plugs, turning lights and such, where technology intersects with culture. I’m looking forward to his next project, because this one wasn’t for me.
>It's an empirical science because the mathematical tools we possess are not sufficient to describe the phenomena we observe and make predictions under one unified theory.

To me the deep learning is actually itself a [long-awaited] tool (which has well established, and simple at that, math underneath - gradient based optimization, vector space representation and compression) to make a good progress toward mathematical foundations of the empirical science of cognition.

In the 90-ies there were works showing that for example Gabors in the first layer of the biological visual cortex are optimal for the feature based image recognition that we have. And as it happens in the DL visual NNs the convolution kernels in the first layers also converge to the Gabor-like. I see [signs of] similar convergence in the other layers (and all those semantically meaningful vector operations in the embedding space in LLMs are also very telling). Proving optimality or similar is much harder there, yet to me those "repeatable controlled experiments" (i.e. stable convergence) provide strong indication that it will be the case (as something does drive that convergence, and when there is such a drive in dynamic systems, you naturally end asymptotically up ("attracted") near something either fixed or periodic), and that would be a (or even "the") math foundation for understanding of cognition (dis-convergence from the real biological cognition, ie. emergence of completely different, yet comparable, type of cognition would also be great, if not even the much greater result) .
Corporations have always been greedy. The narrative that inflation is caused by greed makes no sense. Something else must have changed.
Wikipedia has categories that from what is perceived, should form a DAG (Direct Acyclic Graph). But very often they don't. I saw this with my own eyes when tried to implement "DagView" (a visual control trying to navigate DAGs similar to trees). So you keep opening sub-categories and one of them suddenly is a super-category noticed before. This indicated for me that despite the fact that DAGs have luxury of having many "parents" it doesn't make things easy in the heads of those who try to work with them. Probably our brains are not very good at dealing with non-hierarchical structures

Use ChatGpt.

Screenshot the math, crop it down to the equation, paste into the chat window.

It can explain everything about it, what each symbol means, and how it applies to the subject.

It’s an amazing accelerator for learning math. There’s no more getting stuck.

I think it’s underrated because people hear “LLM’s aren’t good at math”. They are not good at certain kinds of problem solving (yet), but GPT4 is a fantastic conversational tutor.

> no, my argument is that the tool being run by midjourney makes them liable for how it is operation. because it's their model, their program, their computer. They are responsible at every level.

I still don't see how this would be any different from something like Adobe hosting a cloud-based version of Photoshop. Someone could use that tool to create an image that infringes on someone's copyrights, but I think you would be hard-pressed to convince people that Adobe is liable for the drawings that other people create with their tools.

> not sure why you think that's relevant, but yes google is liable for copyright infringement facilitated by their platform. that's why if you upload a full-length video to youtube and the rights-holder posts a DMCA, google will delist or delete your video.

The YouTube case is about Google themselves redistributing the copyrighted material. The distinction with the Google Docs example is that Google isn't distributing the copyrighted material, it's just a tool being used to facilitate the creation of that material.

The JavaScript remark was just because you implied that it made a difference whether the software was running locally or on Midjourney's servers. If that's the case, I want to know where you think the line is drawn between the two situations.

So, no, I still don't see how this is as cut and dry as you claim.
They got some fame because they were posting “too many updates” this morning due to the earthquake/tsunami and got blocked on Twitter and had to tell people to use their app instead.

That’s the reason I heard about them, for the first time, this morning.

I saw the name and had to go digging to see if it was real (yes), if NERV was a real government agency and not fictional as I always assumed (no), or if they stole the name/logo (no).

The problem with native has always been that

* Users expect consistency within their apps, and will complain loudly if platform A has something that platform B has not

* the native platforms’ rendering technologies are so different that you basically need a developer or team dedicated to each platform, with their own test infrastructure, etc.

* even if you can afford to do the above, herding four teams using different technologies to do a coordinated feature release schedule is like herding cats

In any case the native platforms hardly do much better. There are plenty of Windows, Mac, Android, iOS applications from ten years ago that don’t work well today, for instance.
A car doesn't have to have been made in the last 30 years, that's arbitrary.

Many cars and trucks from the 70s had manual steering and brakes, Ford F series, Jeep CJs, etc.

My technique is to power cycle the car just long enough to reset the radio. Also, the steering lock is easily unlocked quickly using the key, it's not as if I take the key out of the ignition and throw it out the window. There are also 2 positions on my ignition, like most cars. You can turn off the engine while keeping the accessory power on. That matters in my case because my car has fully electric power steering.

Many "hyper milers" do things like this. There is a almost 10 mile long section of I-70 that is a famous grade. You can coast the whole way down. I used to coast down the whole thing in my civic, others do too.

Really any car that can be flat towed can be safely driven with the ignition off. You see people doing this all the time, towing a car with a tow strap and a person operating the steering and brakes in the under tow car.
> at worst, fail2ban: causes you massive inconvinience or total lockout [...] it'll probably block you out.

I agree that fail2ban is useless once you've disabled password login, which you should have done.

But is anyone really getting locked out of their own systems by fail2ban unless they're doing something pretty weird? I thought it gave you about 5 password attempts, and then blocked you for 10 minutes - doesn't seem that draconian to me.
What do you believe is the purpose of copyright law? Genuine question, I’m curious to hear your take.
So this is a book written by applied mathematicians for applied mathematics (they state in the preface it’s for scientists, but some theoretical scientists and engineers are essentially applied mathematics). As a result, both the topics and the presentation are biased towards those types of people. For example, I’ve never seen in practice worry about the existence and uniqueness conditions for their gradient-based optimization algorithm in deep learning. However, that’s the kind of result those people do care about and academic papers are written on the topic. The title does say that this is a book on the theoretical underpinnings of the subject, so I am not surprised that it is written this way. People also don’t necessarily read these books cover-to-cover, but drill into the few chapters that use techniques relevant to what they themselves are researching. There was a similarly verbose monograph I used to use in my research, but only about 20-30 pages had the meat I was interested in.

This kind of book is more verbose than my liking both in terms of rigor and content. For example, they include Gronwall’s inequality as a lemma and prove it. The version that they use is a bit more general than the one I normally see, but Gronwall’s inequality is a very standard tool in analyzing ODEs and I have rigorous control theory books that state it without proof to avoid clutter (they do provide a reference to a proof). A lot of this verbosity comes about when your standard of proof is high and the assumptions you make are small.

It looks like there is this secret society working hard on making people suffer in a hotel rooms after long trips. Blue TV indicators, white and blue air condition panels, impossible to cover LEDs that are attached to fire detectors.

All of that to make sure the room stays as bright as possible the whole night. I am always impressed with the efficiency of these little, bright, things. In terms of a brightness per cubic meter efficiency.
Hmm no but the intense deep blue is not good for the eyes and can even damage the retina at intensity.

Green or red don't have this issue.

It also has a noticeably different refractory index which is why red directly beside blue looks 'off'.
Micromouse competition is exactly about this. There are plenty of algorithms published. Some version of flood fill is the most popular I think.

Reading a Doctorow article like this, I get the sense that he thinks it would be a swell idea to force everyone by law to surrender all private property to the benevolent care of the state.

I really like leaving a unit test failing at the end of a session. Its much easier to write it at the end than the beginning and they are often pretty easy to complete. Its a surprisingly simple way to get back into things the next time you pick it up and it is I think superior to just leaving a todo list of microtasks because it solves the problem of what precisely you need to reload into your brain to get going, the approach is at least for the first 10 minutes already decided.

> the moment the industry went to SSH Keys en masse [...] fail2ban stop serving any real purpose

That assumes people only use it for sshd, no? Which isn't the case [anecdatum] for me, at least - I use it for ssh, http (several servers), imap, smtp, mqtt, etc. Make a request for phpMyAdmin pages on my server? 10 day timeout for you, sir. IMAPS connection with incorrect username? 10 days in the bin. etc.

Yeah, it reduces log entries but it also reduces unwanted resource consumption and keeps my servers working instead of chugging under non-useful load.
Yeah I can see me earlier comment breaks the rules right there.

Show HN: High Altitude Balloon for this year's eclipse
Hi HN,

I've been working on a high altitude balloon along with a team of volunteers that is going to take pictures during this year's solar eclipse. The balloon has a gimballed camera (or more accurately, a gimballed mirror) that autonomously tracks the sun. Real-time video is sent down to the ground via 70cm ham radio. The comms was developed almost entirely by myself, and on previous flights we've tested it to a range of 140km. Along with the real-time video, it also uses spare bandwidth to send down high resolution from several other cameras on the payload.

Aside from the project website, I also wrote up a short article on one of our previous launches. It focuses primarily on the communications system since that's my contribution to the project: https://www.scd31.com/posts/real-time-balloon-video

I hope you like it, and I hope to hear your thoughts. Thanks!

Interesting idea! Along similar lines, this year, I am planning in terms of number of hours available in the year and how I want to allocate those hours, without binding them to specific dates. We'll see how it goes and whether or not it helps me accomplish what I want to accomplish.
I think the misunderstanding is how to hit the DOM. If using static methods the performance cost is a memory cycle, so there can be many wasted steps and it’s still negligible. If access is via query selector then there is a string parse operation which is a few orders of magnitude slower. That does not mean the DOM is slow. Even Lamborghinis are incredibly slow if you never move out of first gear.

Shouldn't you watch it at all times, since it's not reliable? Sounds more like a gimmick to me, just driving the car yourself seems less tiring than constantly hovering over an ai-driven car, being ready to take over in an instant.
In one of my previous jobs, it blocked me out after 3 attempts indefinitely - that is, until I got a hold of the sysadmin and asked him to unblock me. It was a PITA, as you can imagine. And I don't understand why any sysadmin would want to put themselves in a position to get bothered regularly by people who tend to mistype their passwords like me.
