>"“We discovered that if you actually treat rust chemically, it actually becomes reactive,” D’Arcy explained. “So something that we typically think of as waste turns out to be a useful chemical for producing materials that can be used for storing energy.”

The pigment in red bricks is partially derived from rust, which inspired the researchers to take a closer look at the structural properties of bricks to see if they could be converted to an energy-storing device called a supercapacitor.

The intricate porous interiors of bricks turned out to be an ideal space to introduce sophisticated polymer coatings, which react with rust to increase the surface area and conductivity of bricks.

As a result of the modifications, the team was able to engineer a prototype smart brick that stored enough energy to power the green light. The team is currently building on its findings by manufacturing specialized bricks with various metal oxides and polymer coatings."

My thoughts:

Character A: "It's a brick!"

Character B: "No, it's a supercapacitor!"

Character A: "Brick!"

Character B: "Supercapacitor!"

Character C: "Hey, you're both right!"
China's hiring of top experts in the semiconductor industry started waaaay before the US pressured TSMC to drop Huawei.
Another option is to learn Graph Databases. I notice there's still a big shortage in people with Graph DB experience, and they're not that hard to learn. Try Neo4J, for example.
Yeah like what @encom mentioned below. I don't know about others but for me* it was a complete disaster. Your hands are always in one place.
The posture is very similar to the posture that is required when lifting a single dumbbell with both hands. Hands are side-by-side and your hands sort of form a triangle. This posture also causes shoulders to hunch forward to make up for the hands stuck close together.

Sure. It might work really well for everyone. Not for me. I am going back to normal typing once I heal. It wasn't really that bad. Just a few errors here and there and slightly slower typing.

Are you sure that it wasn't due to the fact that Intel Atom doesn't have AES instruction set[1]? I think openssl uses it a lot so it would explain this huge difference (since looking at the clocks, AVX/SSEs etc. I would expect at most ~50% difference looking at single core of Xeon vs single core of Atom) unless generations of Xeon and Atom were many years apart. I think newer RbPis CPUs have AES instructions so they could be faster than Atoms in applications that utilise it.

Yes, that's wrong. I'm not sure about the CEO number, but Mozilla's 2019 reported revenue was ~$450M.
if your use case lets 'your program and language runtime fit in L1 i-cache', it's not a big data use case - engineering for big data tools is not the problem, deciding this is the 'problem' is.
I only tangentially follow the news (original backer for the $35-whatever-tier), but last I checked, there was a reality check ~1 year ago.

They actually hired and empowered a PM to ride herd over the project (including Chris Roberts), and that's helped with forward progress.

Previously, it seemed there was a lot of unnecessary technical churn for artistic reasons. E.g. the "We can make this thing 5% better, but it will take a 50% increase in time because we'll have to rewrite a lot of code" request.
Great insight, this is a general issue with making decisions based on predictions. It comes up in Hanson's "Futarchy" / decision markets too.

For example, if you have a huge bias against recruiters and never take their calls because your predictions are < 3%, but the true probability is 50%, you'll never find out those predictions are wrong.

One way to mitigate this is to add random exploration. Whenever you decide not to do something, with probability say 1/20, just do it anyway.

For most Linux distros, I make a custom update and reboot command because typing in the three or four commands to perform full upgrade/update and reboot is a pain in the ass.
The purpose of a PDF is to have a document that can be viewed and printed as designed and laid-out by the creator. HTML doesn't do that. The experience of an embedded PDF viewer is still pretty horrible (even new browsers have a pretty bad experience, and well, even Adobe Acrobat's UI is just... bizarre).

PDF supported embedded type, vector graphics, and many other features long before the web browser could. Honestly, the issue with pdf is how documents are created (often via fake printer drivers that often compile/translate whatever you are printing to some pretty gnarly postscript).

There is a literal difference between saying "German people are Nazis" and saying "Hitler was a Nazi", the latter shouldn't be censored, but context matter.

Given a specific German person that happen to be a Nazi and using that fact to insinuate that Germans are Nazis, would not be OK.
I'd want to - or rather, the idea of managing a series of applications in a distributed fashion is interesting to me.

HOWEVER, i like to write distributed software that i want "uninformed" users to run. Aka not run on nice, automated k8 deployments - but on dirty, random computers.

My current idea is to run this software on all my personal PCs, but also a couple RaspPis over wifi in random locations.

Slow, poor connectivity machines sounds like a decent and predictably bad user environment.

Yes! Don’t forget the time Firefox, bastion of privacy, forgot to update a critical cert that allowed addons to work, and then said, “don’t worry guys, the whole time we had the power to force our updates without your consent, under the guise of an analytics feature, and we used that to fix this!”

> There is no plausible solution for multitude of reasons listed in other comments.

Is that really plausible though? I'm sure it's technically doable, but I'm not sure it's realistic or even a good idea if you could pull it off.

Who has the ability _and_ incentive to carry out such an attack? You could hire someone to do a DDoS attack, for example, but who would pay for that?

Let's say you've pulled it off. Have you considered the collateral damage?

Can we be certain that whoever has the capacity to do this will only ever use it "for good"? What's "for good" anyway?

Have you even considered that not all the people who remained connected in the country may be government officials? I don't know about this specific Internet blackout, but quite often other organisations (e.g., international NGOs, consulates/embassies, hotels) remain connected (see this for example: https://qz.com/africa/1884387/ethiopia-internet-is-back-on-b...).

My First Post on HN:)
I'm just wondering how to use HN more effectively.
I am a vim user and didn't remap esc. I use my ring or middle finger to hit esc which means I leave the home row (shock horror) but my wrist moves less far than if I use my pinky and I can find the home row again without looking

Hand angles and wrist position are somewhat glossed over if you only know "finger x presses key y"

If you think about violin and guitar - you learn how to play the same note from different hand positions so there is some (small) potential for this on the keyboard
I think this study underestimates the number of Americans that just stay home and die on their own or who get turned away to die on their own. With medical costs where they are it's pretty standard for poor families to just handle things on their own.

People in nursing homes tend to get sent to hospitals on the drop of a hat, being bounced back and forth from ERs. Not surprising that their numbers are a lot higher.

Also true in the US. Different in structure and rhetoric, but still basically true.

If Boeing hires a German, it doesn't get framed as "US poaches from Germany", with a subheading of "a US-backed aerospace project" like in this article. They'd just say Boeing.
thanks, jimmies! we do not have a dedicated microphone feature at the moment, and we did encounter a small amount of lag, but it varies based on device model. we hope it won't be an issue for our users. regarding the setup, we're aware of the driver dependencies, we're planning to build a complete Mac app instead of the plugin we have now, and to add Windows support soon as well. about Linux, it's not supported at this point but on the long-term, we want to have compatibility with all operating systems.
I thought this article, while a little dry, was very illuminating. It sounds Hyperfeed is running at the very least "Medium Data" (we all thing our Data is Big!). And i think it is fascinating to hear of a case where Prometheus is plainly a bad fit for it's intend purpose. It sounds like cardinality explosion around their ML models was a really bad fit for Prometheus. Its great to hear about deployments "in-situ", and people appreciating where it works well, and where it doesn't.

Ask HN: How much is yourname.com worth it to you?
I've received an email from a human (sent something related to the content of my website) asking me to sell my domain name (alextoussaint.com) for $2k.

I'm using it as a personal page and for emails. I don't need that money but getting a 200x ROI on a $10 investment made a year ago seems appealing. But, I fear to regret it in the future (10-20 years from now) where .com's will be very scarce.

So, how much do you think this domain's worth it? Have you already regretted selling one?
Will this negatively effect strength or endurance of workouts?
that's a nice website. pls add a page to tabulate the differences among the three paid plans listed there: essentials vs producer vs high-performer .
I've heard one is supposed to use the palm to press Ctrl and not pinky. Though IME the palm is awkward and difficult to use precisely. Maybe it gets better with practice.

Swapping control and caps is another alternative, though in that case it's still using the pinky.
Gotcha! Thanks for the replies. A really interesting area and very hard to quantify overall either way. I find that usually when people frame it in the terms I did, most people (not you because you seem very considerate already!) think about the post-war pre-70s generations in more kindhearted terms.
We open-sourced it under Apache 2.0 which we find quite permissive and OS-community friendly. You're welcome to run a hosted version. We actually have it running on dstack.ai (it's free currently but we of course plan to have paid features if there is such a need).

TL;DR: There's probably not an obvious, "learn this and you'll increase your job prospects" technology for you at this point. But, you can also decide to learn almost anything, and because of your years of experience, open up a ton of new doors.

I'm also a self-taught engineer (well, I've done course work now, but only years after starting in the field).

If I'm reading this right, I think you're in a position where there's not an obvious next thing to study, as you've more or less become an expert in CRUD applications.

I think a lot of developers hit this point, especially us self-taught types. When you're making your way in the industry, it's really easy to notice the in-demand skills/technologies that you don't have, and to add them to your toolkit one at a time. It's a nice, linear progression. Then, you reach a point where that approach doesn't work anymore. If you're a 10+ year developer who knows React and Vue and is strong with vanilla JS, adding Angular to your toolbox won't raise your salary or your skills—you could probably pick it up on the fly if you really needed to.

I think at this point, you need a paradigm shift away from "what is the market pulling me to do" and "what do I want to do." It sounds like you want to stay an IC, so that means it's going probably going to be purely technical—so what technology do you find interesting?

For me it was machine learning, and then hardware-level stuff. That's what lead me to take university classes and study higher math/more fundamental CS. There wasn't an obvious pull in that direction from the market—none of my bosses offered me a raise if I became an ML engineer—but I liked it, and because I had years of experience already, becoming proficient in the field opened up an entire new world of opportunities in terms of career and personal life. I wasn't a new grad who studied ML. I was a career developer who'd built businesses, who now had a background in ML.
You could apply this same logic to any new field you study, it doesn't even have to be technical. If you got really into design, you'd be a designer with 10 years of development experience. If you got really into sales, a salesperson with 10 years of dev experience is a hot prospect at any company that sells to engineers (in other words, some of the most valuable companies on Earth).

If you want to stay in web development and level up there, I'd recommend following the advice of many on this post. Pick a part of the stack you find interesting, and dig a thousand layers down. Even better, if you find something you think could be done better than the standard tooling does it, build something there.
The UK doesn't have a uniquely large number of restaurants and cafes, nor are the UK's cafes and restaurants uniquely affected by the lockdowns.

When they say the UK has a strong service industry that drives exports etc they don't mean cafes and bars they mean financial, legal etc services. Those should have stayed strong. I suspect some of the decline is actually Brexit related decline in financial services.
An update...

We got rejected again. This time the Apple tester had trouble logging in. They used the same registered email as last time, but didn't follow the instructions to login instead. What is weird, they also gave a comment on the subscription text you only see after you login.

So back we go again and try for a new build today, and wipe out their previous IDs.
I know it's all random chance, but I like to think that when that sort of thing happens, it is legitimately the universe telling me something.

Maybe you're going to be hit by lightning?
It's quite concerning you can open a Revolute account without ID. When I opened a Monzo account it required a pic of my driving license (despite having already recommendation from existing clients and passing the E-Check process with Address\Name\DoB etc).
Executing a lot of ideas builds your ability to execute. I believe that.

They have, and it works well. Also, you don't have to use it so they do it fact give you a choice.

But the article is about Google as search, only, which needs no customer support, since it requires no account.

Whether Google (or other companies) provide support for their free consumer accounts is a totally orthogonal issue -- and I haven't heard anyone claiming that Gmail or Docs or Drive is being anticompetitive and needs to be regulated.
This could be survivor bias. I hunted and pecked for the first ~15 years without pain. Then had problems within the first 3 years of touch typing. My guess is, like sports, some people won the genetic lottery and/or had training and time to perfect their craft more easily than others.

Genuine question for people: When I read about things like gesture guard, head bubble, virtual backgrounds, etc., I cant help but wonder why they’re so important.

Is it really a problem if you sneeze or cough during an online meeting? Are you colleagues really making this an issue?

Likewise, I’m fascinated by the focus (ha ha) on hiding backgrounds. Why is it so bad to show people where you are?

I’m clearly in the minority in that neither of those scenarios are even remotely (ha ha) bothersome to me or my colleagues. But from their overall thematic popularity, obviously these are real issues for people.

More accurately: "Learning to touch type made me an expert typist. Also I bought a keyboard with blank keycaps."

I get that you could cheat if you had a regular keyboard, but if you're learning to type, why would you do that? And even if you do cheat and look, you could still practice the hand movements.

With that said, I learned to touch type in 1-2 weeks with _The Typing of the Dead_ on a Sega Dreamcast and this keyboard:

Libertarianism doesn't advocate for do whatever you want. They advocates the principle of non aggression where your freedom last until you interfere with another person freedom. Classical libertarianism advocates that freedoms comes with responsibility and is not free. The socialists likes freedom without costs using the state as a medium for liberating you from dutys. Libertarians advocates for the rule of law and respect for every individual.
It is mind boggling how smart and clear thinking people want so badly to dump on Microsoft, to the degree that it blinds them to objective reality. Auto driver update functionally is now in windows update and it works well. This is mentioned in the article. They are killing this because it's broken and they don't need it.
Many people don't have a room in their house or apartment that they can dedicate to creating a home office, especially people with kids, and have to use a shared room.
