Graphene's cousin, carbon nanotubes, have been touted as a concrete-strengthening additive for some time now[1], but the downside seems to be that corrosion sensitivity is increased.[2] Curious to see whether graphene would really be immune to that as is claimed.

"And when, eventually, these things do reach the ends of their lives, if the graphene can be recovered and used again it would be a welcome boost to building a circular economy."

This just sounds silly/unfeasible.

I don’t know about Tesla specifically but this is a thing that some EVs can do. The new Ford F-150 lightning can do it. This is generally called vehicle to grid, vehicle to load, or bidirectional charging. A quick search shows maybe Tesla hasn’t added it yet. But here’s some details on the Ford lightning setup:

Rust Governance Update from April
You’re missing that Russia started this with a much lower base. Increasing prices and decreasing growth for an average North American or West European would mean that they would have to go somewhere cheaper for vacation this year and slightly adjust their consumption habits. When your net monthly income is ~$500 or less you might have slightly different concerns if you see prices rising by more than 20%.

> and even more so if Russia turned off the gas tomorrow.

Energy exports are the only thing keeping the Russian currency afloat, unless they want to go into full autarky mode this would hurt them more than the west (i.e. 40% of all gas in Europe comes from Russia, which is huge 80-90% of all Russian exports are fossil fuels and metals and most go to Europe).
As someone who lived next to a busy road for about 10 years, I’ve always wondered why people do this, so thanks for the perspective. The apartment was about 10 feet away, with no isolation, and a 65mph speed limit, so, surprisingly, it was worse when there were fewer cars because people would throttle harder. So because of this past living situation, I’ve grown to hate the noise of loud vehicles at any time of the day, and if I were given the opportunity to limit the amount of loud vehicles on the road, I’d always take it. Eventually I bought sound panels and put them in my road-facing windows, and then also in my rooms closest to the road, but eventually I decided it would be best to just move.

Very cool. One use that comes to mind is encoding chords. They usually consist of about 4 (or fewer) notes chosen from 3 octaves (36 notes). It could have applications in machine learning.
Sorry, but I find this approach very rude to your customers. It's kinda your job to make it work on your side and don't transfer the burdens to clients.

I don't know what your SAAS does (maybe it's not really applicable here), but in the case of github, it's very wastefull. Yes, it would take some work, some servers, etc but they have the skill, the money and everything they need to do it. They could do it once (well, with every change, but it's not very often) on their side instead every client on every pageview will have to do the same work again and again, wasting time and energy.
Please don't make "riding motorcycle" out to be some kind of heroic, selfless act.

I don't ride a motorcycle. I also don't have a car, by choice. I use busses, bicycles and the occasional taxi, and make sure I live within walking distance of essentials. And yet, even I don't tell myself lies about how things are much better on the road because of my choices.

If I ever do choose to ride a motorcycle, I will keep it quiet and accept the risks like an adult.

If you tell yourself that you're selflessly helping humanity and then only "do my best" not to make noise in residential areas, you're a problem. Just admit, to yourself at least, you like to piss people off - or worse maybe you just don't care.

This entire post is full of people talking about how people like you are a problem, and yet you tell yourself that you're actually a hero. Look inward.

That's not true, the point is that you fingerprint using misconfigured hosts, they never get the intermediates through them.

> My personal experience is that people who describe their abilities like you do are actually not very good at their job but think they are.

I respectfully have a complementary but somewhat different view (again, with full respect-- your personal experience is not mine)

The author describes themself (humbly) as a 10x developer. And they seem to think "10x developer" means a person who fills the pareto principle (the one person who does 80% of the work). The author also has stats to back this up, and again, I stress that they are humble about it.

As another poster mentioned, a "10x" is not the person who does 10x more than anyone else, but rather the person who allows many many other people to do 10% more than they could otherwise.

As I see it, the author has grown to the limits of what their company offers, and should indeed interview for other jobs. Not necessarily take a different job, but to get a different benchmark for their abilities.
It seems to be a prevalent practice of local subsidiaries of international courier services.

In Serbia, they will each charge you a different amount (DHL 3240 RSD or slightly less than 30€, UPS 4800/40 and FedEx 5400/45) for being an import agent.

Officially, you can use another registered import agent (some of them only charge around 10€), but it's a bigger hassle.

Locally, UPS tries hardest to avoid charging you for their service, but the best trick I found is to look for web sites shipping with import fees prepaid (eg. Amazon, as much as I hate to say it).

Alternatively, shipping with regular postal services works much better in Serbia too (if they submit your package for customs inspection, you only need to pay up to a 3€ fee), so perhaps look for components shoo which ships with regular post.
That's really nice, thanks for sharing!
The title is somewhat hyperbolic.

It's safe, but the point the author makes boils down to "it's hard to administer in organizations, debugging is especially difficult, therefore more security failures can occur".

Errrr... nice website, and I totally support the idea of using night trains instead of (short-range) air travel, but this website (although very nicely done) feels more like a glossy brochure, to actually find out what trains are available apparently you have to install the app?

I can't agree with any of these perspectives, or the analogy to being a musician.
Also, I find it to contradicts itself.

Initially, you say: you need the core knowledge of algorithms and data structures (like the circle of fifths and harmony) to do sophisticated improvisation.. so you're advocating for the importance of having a strong technical background. OK, fair.

But I don't get your analogy to a rock band going on tour, and they either have it or they don't? What is the software analogy to going on tour? Is this working in a startup, when you just need results rather than finesse? How does this tie back to your initial point about jazz musicians needing a core base of knowledge?

You also bring up the myth of the self-taught, scrappy musician (or programmer) who, against all odds,'has it' and is able to exceed the abilities of others who are the hardest-working and most studious.

I find this concept pretty toxic. The Eric Claptons and the Jimi Hendrixs of the world are a rarity, a complete exception. Although often cited because they are incredibly visible, compared to the hundreds of thousand if not millions of others who either developed skills and capabilities through education and/or self-taught effort. Often without 'having it'. I think it can be pretty discouraging when everyone holds themselves up to ideal of Claptons and Hendrixs.. rather than considering there might be multiple, varied and nuanced paths to being an excellent engineer, or musician.
There's probably going to be a very large supply of carbon going cheap in the near future, we should start working out what we can use it for.
The authoring date is, yes. But not the "remind me at" date.

As for author: yes definitely. And it's a great fallback option. But it's not visible in most code review UIs, and even when it is it tends to be the most recent editor, not the author. Git's CLI makes the full history of a line pretty easy to read with -L (usually, depending on if it detects a move or not), but have you ever tried to do that on GitHub? Back through several versions? It's a freaking nightmare, and nobody will try to do that while reading a diff.
It’s practically impossible to use Bitcoin as digital cash because it’s so slow and expensive. That was the original problem it purported to solve, but it failed miserably at that.
So I'm skeptical of web3, I dig cryptocurrency but all this nonsense about NFTs and metaverse and whatever is just that, nonsense.

But there is one glaring mistake in the article, and one I often see in arguments against web3, that is the idea that the internet becomes some pay to play thing.

First of all, running services costs money. Running services for free costs money, it just doesn't cost you money. So you're asking someone to either do you a solid, or get paid another way. And 9 out of 10 times they choose the latter, and track you and sell the data. You pay, one way or another.

So all the concept does is allow people to pay for services they use that someone else provides them. Think about renting a rack vs a vps, now imagine making that sort of service more granular. Things get cheaper when you do that. Things become more egalitarian, you're on equal footing online with providers. When was the last time we could say that?

And when someone tries to make a web3 version of something that doesn't require all that nonsense, people will make free alternatives. And if those alternatives serve the same needs, the ones that cost micro transactions will wither on the vine.

So the market takes care of it. Web3 will serve the roles that it serves best, and things that are better done different ways will be done differently. I'm skeptical of anyone telling me the world will run on this stuff, but to say it doesn't offer some utility, at this point you're deluding yourself. Time will tell what utility it truly provides, but one thing's for sure, this idea of a free as in beer internet isn't working out.
Far and away the most reoccurring noise for us is airplanes landing at Bromma Airport in Stockholm, Sweden. Because half of the city is in the descent path, we get low flying commercial airplanes, sometimes a dozen an hour. Incredible how it’s even remotely legal. Especially since most plebs only go to Arlanda Airport, which is an hour away by car. Politicians and businessmen use Bromma.

Second loudest noise is heavy traffic, like trucks. They always seem to be speeding in low speed areas too. I only noticed because my daughter would wake up because of them.
> Art certificates, both physical and digital have existed for… ages?

and they are generally pretty crap? easily lost, forgeable, destroyed, manipulated, unrecognized.

typical certs require a centralized "Certificate Provider" who upholds their value, for example a major auction house might distribute a cert when selling a painting. in crypto art there is no centralized authority that maintains the veracity of the tokens as the provenance and ownership lies in the distributed ledger.

for those who wish to achieve similar goals as a digital cert but with more cryptographic robustness and less reliance on a centralized actor, NFT is a fine approach. that it has sales and market mechanisms built in is a bonus and probably the reason for its booming success as a new digital art market.

Using Docker Containers to build your Code
I don’t think it makes sense to see built in operations on arrays and maps as generic functions. If 'len' was some kind of built-in generic function then you'd expect to be able to monomorphize it like this:

func intLen(foo []int, lenfunc func ([]int) int) int {
return lenfunc(foo)
}

intLen([]int{1,2,3}, len)

There is just no sense in which Go 1.17 has “generic types” and (e.g.) C doesn’t. All statically typed languages allow you to define arrays of different types and use the same operators on these arrays. Go adds a handful of additional built in types (slices, maps, channels).

The idea that some completely ordinary language features somehow constitute a crippled version of generics that has been 'turned off' for regular users seems to be an artefact of certain communities' hobbyhorsing over Go's (former) lack of generics.
Phasing out old.reddit.com would cause such a riot that the Reddit bosses have decided to make it more and more nonfunctional until most people have migrated out of frustration to the new version.

Sometimes Hanlon's razor is wrong and it's malice, not incompetence.
Reddit user experience is awful. I like the Reddit communities I follow but my god is it annoying af to use it on mobile browser or even the desktop client. I don’t want to install your app. Deal with it, because I’m dealing with it by not using it and I hope more people follow. The app which I’ve tried crashes often, and the video auto play sometimes breaks which is annoying and requires a restart. If I was logged out and login, I get taken to the fucking home tab. Why doesn’t it redirect me on the page I had open, I mean I can understand not being able to code (considering half the other stuff that doesn’t work) the position in the thread I was in, but at least put me on the same thread. Anyway GG no RE, barely use Reddit anymore because of this poor ux.
I'm grateful for this. It's a good incentive to finally quit Reddit completely. It's pretty much down there with Facebook these days but so far I've kept scanning it out of habit. But the new UI is so bloody toxic, I'd rather quit than undergo that.
Honestly, I went read-only on reddit via teddit.net and blocked main domain (reddit.com) in /etc/hosts. This forces me to make a conscious choice on opening a Reddit link.

All the forums that Reddit took over are making a comeback, this time with Discourse (probably Baader-Meinhoff, but I'm seeing it everywhere now).

Reddit had a good run, but as a place for real people to go to, its time is over.

> It would be so nice if you could just like, I don't know, bump two devices together and they use NFC to pair or something.

That's a thing on higher end kit. Has been for years. Obviously only works if both devices support it though - you won't pair your macbook for example.

Other than that, I find Bluetooth and wired set-ups both have their advantages and disadvantages:
- Bluetooth gets difficult when there's interference, wired gets weird ground loops and interference.
- Bluetooth can be tricky to connect, wired gear gets yanked out of my ear when it catches on my door handle, or an airplane seat armrest, or my dog.
- I can walk around listening to something on my laptop with Bluetooth, but with wired I don't have to worry about battery life.

Bluetooth is an essential part of my life and has been for probably 6-8 years now, so I've worked out most of the tricks and kinks of the gear that I use.

But how does that apply to GPU ALUs? Looking at M1 die shots, they are comparatively tiny, and when comparing to other vendors, it doesn't seem like Apple is dedicated more logic space to the GPU. The M1 die is roughly 120mm2, an Nvidia Turing TU117 (GTX 1650) is roughly 200m2. Both feature the same amount of GPU ALUs (1024 32-bit units). And of course, M1's 5nm is around 5-6 times denser than Turing's 12nm, but M1 is an entire SoC with all kinds of components — not to mention a huge cache — the GPU takes maybe 20% of the die (let's say 1/3 if you also count in the display controller and memory controllers). All in all, the amount of normalised die space dedicated to GPU ALUs seems comparable.

Of course, my perspective here might be extremely naive, I know very little about semiconductor technology, just trying to understand the principal design differences.
It generates a huge amount of noise, this feels like absolute gaslighting. Even just going flat a skateboard is incredibly noisy, as soon as people start doing jumps or tricks it's ridiculously noisy.

And incredibly repetitive, people trying to do the same trick over and over again.

Show HN: Enioka Scan, an open-source Android library for barcode scanners
And the wheel of re-innovation turns yet again.
Lol, what does "knowing what you're doing mean?"
I live in Stockholm and I'm originally from São Paulo, Brazil. Bromma is quite annoying (even more when I lived around Sundbyberg) but is still relatively tame compared to Congonhas airport in São Paulo.

Either way I can't believe that both airports are still allowed to operate, I lived under both on/off-ramps and even though your mind learns to filter out the noise there's something you can still feel under your skin every time a plane buzzes by...
Enioka Scan is an open source Android library that makes the integration of barcode scanners in your Android applications easy while avoiding vendor lock-in.

The library provides a common layer of abstraction on top of a scanner's SDK, which is often specific to its vendor and sometimes proprietary, allowing the use of a single application and API to communicate with any compatible scanner. Some of the supported scanners still require proprietary SDKs that cannot be bundled with the library for licensing reasons, but most scanners are compatible as-is with provided open-source SDKs part of the library.

The library is currently compatible with a wide range of scanners from major vendors like Athesi, Honeywell, Zebra and more. It is designed in a way that makes plugging in your own driver SDK easy, allowing you to add compatibility with other vendors.

The library just released in its 2.0.0 version, bringing significant improvements to the exposed APIs, and support for a bunch of new scanners. Any feedback, bug report or suggestion is welcome!
Also it doesn't focus all its energy on a narrow range of cilia in the inner ear. Like the difference between a small, intense light in your eyes vs. a larger, less intense light.

Spent a bit of time in the metal trade, sometimes various metals that can best be described as oddities from Sheffield would be heading south, one such time some metal pieces were on this lorry no bigger than a chunk of cheese or hash brown thats broken off, clearly its been part of a larger plate of metal, but its magnetic strength was so strong it needed a screw driver to leverage it off anything it was stuck to. Never seen anything as strong magnetically since, but it had became a sort of competition with people/visitors asked to try to pull it off what other metal it was stuck to.

> It is not something you would sell to a scrap dealer,'' he said.

The titanium being sold as scrap would come down in bars which had been angle-grinded all over to produce long metal splinters so that it could only be handled with a fork lift, the splinters would go through gloves if you tried to handle it. That shows to what lengths some scrap metals were "processed" in order to avoid being stolen.
