I primarily use a wireless charger and I haven't noticed any heating issues. It's in a phone stand form factor, though, rather than an attempt to be both paper-thin and lying flat like Airpower, so there's much more area for passive air-cooling.
European cities were very much pedestrian and bike town in the 1950's. In Helsinki they proposed banning bikes from city center, because they caused traffic congestion and gave poorish image of Finland. Bike paths were kept open all year manually. I biked some 10 km to school and every single day dozens of guys had woken at 5 o'clock and shoveled and sanded narrow but adequate bike path just for me.
The usage of natural language to write legislations about internet will always create ambiguities and loopholes. I think regulations should be writen in a mathematical language with proof of consistency and unambigous reference implementation of algorithms that are imposed to FAI.
Almost all professions are going to be using coding (at whatever level of coding) skills in the future anyway (if not already). So let them be interested in a field of their choosing, and then let them know that knowing coding can help them in that field.
There is a difference between developing an interest in a child and forcing them to do things.
I’ve actually done something like this in the past. I was able to identify the IP address of a few content scraping websites, and then made my RSS feed return a huge number of gibberish pages when requested from these IPs. I’m not sure whether they eventually ran out of database space or what happen, but these sites did go down after a few days and stayed down.
https://www.ctrl.blog/entry/defacing-content-scrapers

(I didn’t attack these servers, by the by. They came to my servers and gobbled up all the auto-generated junk I served them all on their own.)

However, in recent years it has been more and more difficult to identify the right IP address as everything is hosted people are hosting behind Cloudflare or do the actual scraping from a short-term lease server with an unique IP.
The one question I have, that I haven't seen answered in the article or elsewhere, is how deliveries are handled. Presumably shops and businesses in a car-free city need to get truckloads of goods or equipment moved in and out on a regular basis. How is it done?

I've always loved the idea of being able to live in a car-free city, but never quite understood how certain things would work, including garbage collection, deliveries, and emergency services, without vehicular traffic.

Or do they make exceptions for all of those? Does anyone know?
Allow me a moment to note the irony of complaining about big announcements in this context.
It always depends on your goal. If you want a quick prototype and are good with javascript, get a board that you can program easily with javascript. But maybe you want to learn how things really work on a low level. Or maybe you prefer to run on batteries for a long, long time. Or perhaps you need the system to have a constant low latency.

It's like, why use other programming languages when $lang is so good. But there's always a possible reason. In the end everything is a compromise.

I'll take the Apple route I think. There is plenty of room for both takes. I won't trash a company because they don't want to compromise their image.

If they feel it's important to have a sleek charger then I'm glad they would rather not release than compromise their vision even if it doesn't matter to me.
>Proponents of the plan say letting Washington impose more tariffs than Beijing would actually hurt the United States more because tariffs are ultimately paid by consumers and businesses in the countries that levy them.

Well, this is actually the fundamental problem, isn't it? There's no way actual trade evens out, so tariffs are the only real outcome here. Even if we "win", it's not actually winning.
Yes, signaling plays a big part. At some point you’re basically buying a gold-plated LinkedIn profile for the VCs and the press releases and the keynotes in industry summits, and that feeds on itself - each new prestigious VP position is another layer of gilt on the CV.

In other words, they are hired to look good - any productive outcome is a mere coincidence.

The Raspberry Pi is great fun. You can build a night vision camera, a robot, an advertising black hole, a vpn server. A retro gaming system etc.

The Make introduction to Raspberry Pi book is the cleanest introduction to computers I have ever seen.

Sit down with your child, put together an order (let them pick the case and components, buy multiple cards so you can swap projects) come up with a few projects and turn them loose or spend time together working on a project or two.

You can’t force interest, but you can share your interests and spend time together. If any of the projects appeal, the interest will be self-sustaining. But if it’s not fun it’ll fall a bit flat.
The problem is a matter of audience and missing communications IMO.

In the old usenet we do communicate DIRECTLY each others so anyone have a reputation, so we know "original sources" and we prize accordingly. In today's world being disconnected, on one side only content producer, on the over side only consumers, in the middle at maximum uncomfortable platforms that are limited and limiting user-user communication it's harder.

IMVHO the medicine is coming back to the communication era we lost in the past, no other systems proved to be effective, take a look a audio/video piracy as a good living example.
I'd say the lack of Tor-exclusive easy-to-use applications. That Tor underpins an application should be transparent. If the Tor browser is the same on the outside as a web browser but slower, the anonymity alone isn't a good enough reason for many to use it. Rather, a (non-browser?) communication platform needs to compete on features and just happen to use Tor.

Some hard-liners want a more aggressive stance. Lou Jiwei, who retired as finance minister in 2016 but is still the head of the country’s social security fund, suggested on Sunday that China could deliberately disrupt American companies’ supply chains by halting the export of crucial components mostly made in China. But Chinese trade experts dismiss that idea as impractical and not the government’s position.

If anything would play into the administration's hands, it would be that move. By taking themselves offline, the Chinese would be ceding market share to upstart competitors and encouraging further reshoring of mission-critical supply chain components.
Interesting viewpoint of the life of genius. I just read a book (Peak, 2016) on deliberate practice where there is compelling evidence that all works of genius stem from very hard work and lots of time.

Is it possible that Ramanujan would not have been so successful had he followed the standard learning path? Is it possible that Ramanujan's genius stems from a "genius" of what mathematical questions he chose to think about?
My advice is don't get them into software before the age of 10. Using the computer too much at that age is not healthy. Get them into hardware and electrical engineering first. That's also something children are more likely to enjoy.

Just because someone can program at the age of 6, doesn't mean they should. It's not a race.
To be fair and a little blunt, this is about founders returning to their product and gives a backstory about those returning. Aaron can't really return, so it makes sense he's not mentioned in this article.

> friends would say oh i cant install clojure because i have to install JVM

It's interesting how in the software world people whom you'd expect to be entirely rational make decisions based on feelings and hearsay. I don't understand this.

I say "in the software world", because I see more objectivity in hardware design. Hardware engineers rarely black out entire technologies just because they don't feel like it.
Longs are not "people holding stock". A long is purchased on borrowed capital paid back with interest. It is a much riskier play.

A short, or short position, is selling first and then buying later. The trader's expectation is that the price will drop; the price they sell at is higher than the price they buy it at later. The difference between the sale price and the buy price produces a profit or loss. [1]

I opened my first actual short position that day (instead of just buying puts). He literally set an upper limit on how much money you could lose and I just felt really confident he was full of crap.

Got out of the position at a bit under $310 so left a lot on the table but was happy. He literally handed people considering opening a short position on the stock a gift.
There is only one way.

They need to come up with something that they are interested in which can be solved with a program which is within their reach.

You can demonstrate, you can make resources available, you can involve them in your own work, but in the end only people who want to make things happen with computers will become excited about programming.
We feed the animals regular chow mixed with a percentage of pure cholesterol (0.5% by mass, if I recall, but I might be wrong). I do not mean a high saturated fat diet.

This is not the introduction of complex "diet" variables as in humans whatsoever. I am quite aware of the differences in various lipids. Feeding animals pure cholesterol is about as close as we can get. There might be studies that have literally infused LDL in animals, I am not exactly sure. It sounds like a huge pain to do experimentally since we would need to obtain vascular access at least each day and risk infection, stress and pain in the animals, etc.

We measure animal blood using the same machines used on humans and see primarily increases in total cholesterol and LDL cholesterol following the diet.

There is not "one good" study for secondary prevention of statins, there are dozens.

There is very good evidence for the effectiveness of dose-response in statins. Again, I don't even know where exactly to start with this body of literature. Look up "high intensity statin therapy." This review for primary prevention, which is probably why it was underpowered in this meta-analysis of 19 trials in primary prevention (where I said the evidence was more equivocal; this study actually shows pretty good evidence for the effectiveness of statins. in 1° prevention). A RR of 0.86 in only 1-6 years is pretty damn good for a chronic disease.

Finally, I think you misunderstand statistics when you say that this review (in which there were only three studies which could be used to analyze dose-response) implies there is no dose response.

When they analyze dose-response (which is done through increasing statin dosage until the LDL-C levels are low enough), I quote: "RR for cardiovascular mortality, 0.61 [95% CI, 0.37 to 1.02]" Yes, this is underpowered because the CI includes 1 but the point estimate of 0.6 is pretty impressive. This is a poor conclusion by the authors via incorrect application of the NHST framework, and not evidence that there is no dose-response effect. The best evidence is actually pretty strong (RR of 0.6 is big!). I personally doubt it's even that big.

Furthermore, RR for composite cardiovascular outcomes, 0.63 [95% CI, 0.53 to 0.76] was very statistically significant and again with a pretty strong signal. So I don't think this paper says what you say it does.

You didn't feel the need to address mendelian randomization studies in 500,000 plus people?
Oh, I tried all kinds of things, each with some level of success but not enough. I was offering a digital double API service to game studios, a web app for digital artists to create characters. The full pipeline was never used, just parts by various clients for customized needs.
> Make programming simple and fun.

Indeed.

And I second that Scratch, which is great on many levels, is especially good as a starting point.

I have three kids (12,11,8) who started at 6+- and still enjoy it extensively.

I made BlockLike.js (https://www.blocklike.org) to make them progress, and it worked pretty good.

> The older they get the more ideas they may want to pursue on their own.

Indeed again.

The older one played with BlockLike, and then went exploring on his own.

He gets ideas from YouTube and just try’s them out. Landed here on the top of the front page with some cellular automata a couple of weeks back.

He is off to trying Python now...
After trying out several CI/CD dev tools for Kubernetes (e.g. draft, skaffold), we saw the problem that there is a lot of waiting time because the images always have to be re-build and re-deployed on every code change. Many developers, including the ones on our dev team, are used to hot reloading tools (e.g. nodemon) and to seeing changes taking effect immediately after saving a file.

While there are some tools (e.g. ksync) that allow to sync files to a pod running inside a Kubernetes cluster, we found them hard to configure and time-consuming to use on a daily basis.

Therefore, we developed the DevSpace CLI, a client-only dev tool that lets you create Kubernetes-based workspaces called DevSpaces. With a single command (devspace up), you can start a DevSpace for any existing dev project inside your Kubernetes cluster (even in minikube). The DevSpace CLI will then synchronize your source code directly to your containers and establish a terminal session as well as port forwarding. It is entirely written in Go and ships with in-built kubectl, helm and docker clients.

I would love to hear your feedback on this tool. PS: It is open source, so contributions are also highly welcome.
I think they got a bit excited with sharing prospective products. In the last year or two they've broken precedent and announced a few things prematurely. For one, they said that they were going to be releasing a professional-level iMac Pro soon (which happened). In the same meeting [0], they said that they're working on a new modular design for the Mac Pro which is probably due next year (assuming they're still on track). I think the feedback from those premature announcements was so positive that they decided to announce AirPower before it was fully matured, and on that one they've paid the price.

I wouldn't be surprised if they turn up the recluse-o-meter once again after this one, and I'm torn about that personally. On the one hand, it's great to see proof that they're working on innovations constantly, and it's neat to see that they don't always work (failure is a necessary component of invention). On the other hand, it's super exciting as a consumer to watch their live events and see something completely new that's available immediately and think "Wow, this is cool!", and that wouldn't happen if they keep pre-announcing things.

If I get laid off and can go out and get another job quickly, yeah I might participate in some sort of class action suit because why not? But I wouldn’t personally waste energy to get a lawyer, and go through the whole process. Instead, I am going to focus on my future instead of dwelling on my past employer.

Maybe we could help determine opinion from referencial material so that we can speed up verbal communication rather than trying to evolve it.

YouTube and Wikipedia working together are good strides. LinkedIn offers suggestions on how to respond to people, then the new Gmail came out with that same feature, I hope Airbnb does too.

Maybe, when using curse words/slang AI could suggest something more intelligible?

If we connected our brains to an emotional evaluator, we could include all the necessary emoji automatically, so we don't accidentally forget that winky face when point out an irony or satire (satire; often mistaken for sarcasm due to different emotional attachments).
So in the last little while, we've learned that WeWork has/had oppressive non-compete clauses, and will no longer allow anyone to expense anything involving the consumption of meat.

This is odd to me, because the people I know who work for them love their job and employer, but it seems like they're moving down a dark path...
You could argue that the entire human body along with every infections disease got invented in the same way.
It's specifically tricky because of the three devices charging simultaneously. As far as I know, no such charger exists. It's a hard problem to get all the circuitry to work correctly in a confined space and handle various wattages and currents at the same time.
>I notice you posted the original article; I'm not criticizing you for posting it but perhaps this is getting personal?

No, but the above is an attempt of second-guessing my psychology (and also irrelevant).

Now, you follow with a long list of opinions of the importance of credentials. What I don't see is any opinion on why the particular arguments are not enough. Can you enlighten us? You could point to someone with credentials which refutes them for example.

If you just want to raise a general principle (totally unrelated to the quality or not of the arguments in TFA) then it seems that you suggest that we should only discuss articles written by people with credentials on a topic.

If so, why should we accept this suggestion of yours then?

Where are your credentials on epistemology (seeing that this
is an epistemological issue)?
Even American chauvinism.
not learning to code is not going to be a handicap through life comparable to being unable to read or write. It just closes off certain professions. Is it cruel to not teach your kids stock portfolio management? Or is it cruel to force your kids to learn portfolio management long after they've expressed complete disinterest in it? I'd say the latter.
Aren't most non-compete clauses just HR stunts? Every time I hear about some company trying to get employees to sign them, that's almost always followed up by a statement saying it would fall apart if it were taken to court.

TIL: Non-compete clauses are the devil and actively screw people over.
There is a lot of technical work to turning an invention into an affordable and dependable product.

In fact, I would wager the majority of engineering/math/physics/etc happens after the proof of concept phase.
This time the shorts really have him. Or do they?

It turned out Tesla wasn't killed by not being able to make the model 3 at all, it wasn't on being able to make the model s in larger volumes, it wasn't because there was no demand, that there would be no demand after various incentives around the world went down (still some left in the us, also available to all other car companies by the way), it wasn't because they couldn't make the model 3 in volume, it wasn't because they'd all catch on fire and burn up in accidents, it wasn't because the over-promised-over-named autopilot was dangerous and would kill people, it wasn't because the leaf, the volt, the bolt, the i3, the i8, and continually forthcoming cars from audi, porsche, ford, mercedes, bmw killed them. It wasn't because there was a secret sec investigation was preventing them from refinancing, it wasn't because they have just lied all this time about selling the cars for less than manufacturing cost (separate from their enormous money spent on infrastructure), it wasn't because the batteries would run down and not survive heat, cold, regular driving, daily driving, supercharging.

It was damn stupid for him to make that twitter comment.
The "winning" scenario for the United States is that China agrees to change its IP policies. IP is America's most valuable product, and the Chinese have been stealing it with 0 consequences for decades. A win on this front would see an end (or at least decrease) in cyberattacks and more US friendly IP laws.

Not really. That would be true if the tariffs were on all imported goods, from all locations. In this case, it just encourages businesses to look at other cheap markets (Vietnam, Mexico, Bangladesh, etc.), hence China's anxiety.
