In this case, the thing we're talking about is a library that uses Rust data types and interfaces.

It might be possible to create language bindings for C or C++ (or whatever language you want to use), but the docs on the website seem specifically targeted to Rust users. So for now, the only people likely to be interested in using this are Rust developers (though people coming from other languages might find the general design interesting).
Its possible to track the coins.
I'm curious, if some innocent third party ends up buying all or part of the stolen coins what are the implications ?

> Is it the App Review process’s role to be the arbiter of what is and isn’t good UI?

Apple certainly sees their role as being some sort of QA gate, and this would fall under that to some extent.
I see it the other way around.

Earthers find it hard to kick the idea that hydrogen and hydrocarbons are fuels, but that is because oxygen is free on the surface of the Earth.

On Luna you might use that hydrogen to reduce hematite ore (found in commercial quantity by astronauts) to Iron and Oxygen. Oxygen is like 7/8 the mass of the fuel you need, you can make storage tanks, residential neighborhoods, whatever you want out of steel if you can find a small amount of carbon. You can recycle the hydrogen, it's not lost as it would be if you burned it.

Lunar oxygen mining to refuel something like the SpaceX Starship faces tough competition from Earth via the SpaceX Starship -- a 1990s study looked at 5 Earth to Mars mission scenarios with and without lunar materials and it wasn't clear you could win with lunar oxygen.

The moon is close in configuration space to the Earth but far away in phase space (including energy differences) NASA figured Apollo hardware could make it to Venus

https://en.wikipedia.org/wiki/Manned_Venus_flyby

because you can use resonances around the moon to get a kick away from the Earth as opposed to fighting the gravity well with a low-ISP rocket on the way up and down from La Luna (no, atmospheric reentry on Earth is not "a problem" but rather free delta-V and one hell of a preimage for your landing site)

A good main belt asteroid might be like Saudi Arabia but with the relative proportions of sand and hydrocarbons reversed. You would be looking at a solar 5km/sec mission unless we got lucky and found a medium rare asteroid in the "near earth" area.

Either way if you could build a chemical factory that can make things like Kapton, Mylar or sheet graphene it shouldn't be that hard to handle giant films to make a solar sail factory, install sunshades at L1, beam solar power to moon bases at night, etc.
I read the title and was somehow was expecting a guide on compiler design implementing some flavor of the the ML language such as Standard ML.
>On the one hand, and for the most part, people have expressed an urge to restore certainty ... Politically speaking, citizens have looked to strong leaders for containment and control, a phenomenon some call the “authoritarian reflex.” And the uncertainty vacuum has been filled by conspiracy theories, war rhetoric, the denial of scientific facts, and an increase in surveillance measures.

Interesting take on the rise of authoritarianism around the world.
>Modern mathematics, like much of science, often isn't directed at real world problems.

So is ancient mathematics. And non ancient mathematics.

A lot of good mathematics is inspired or comes from real-world problems, but even more does not.

At a very fundamental level, mathematics is a curious exploration of an interesting "What if...", where you get to make up whatever you want in that "...", and see where it gets you.
A 'Rash' of Dermatologists? A 'Tantrum' of Decorators? Lol! Is there really some governing authority that declares these things official? I just use the old standby, "Alotta". ;)
I'm sure I'll get down voted, but I don't find the Bay Area all that different. In the Bay Area it's just different towns all interconnected, while in Houston, all those towns were consolidated into one massive city (like LA).

SF is only 1 million people and the dense, downtown core is not that big. Outside of the downtown cores of SF and Oakland, it's all just suburbs wrapped around the bay. And plenty of people have absolutely brutal commutes due to the sprawl.

The only difference is they commute from "another city".
There was a bit more than just Napoleon III getting captured. Paris was subsequently sieged and captured by the Prussians. Afterwards, the Prussian troops were kept nearby and occasionally paraded through the streets. The Commune arose also due to power disagreements with the new Third Republic and an attempted seizure of cannons in Paris.
The linux kernel still can only be compiled with GCC. Of course, it's a single patch away from clang compatibility, but the kernel has never been compilable with much else but GCC.

This is no different from the "first" comments in youtube or when sharing a meme to a friend that has already seen it and says "I've seen that already" instead of discussing essence of the content itself.

Thanks for the article! In this case, this is custom spam from someone that has spent a few hours looking at the network tab in devtools. The bad actor is running headless browsers after we started doing basic cookie and JS checks; we added some additional JS checks for basic things like whether it's a 800x600 window or similar - this stopped the spam for a few days until he figured it out.
In the nearby major city I'm most familiar with, most of the grocery shopping you'd do would be in supermarkets--often Whole Foods some of which on the smaller side. Other than convenience stores, there are also some bakeries, produce stands, and butchers. But most of your shopping is probably going to be at supermarkets (which have parking).
> I'm a software engineer, and I would never want this job. It's got to be incredibly boring and tedious.

That's cool, but testing roles exist throughout the industry and some people choose QA as a career.

I wouldn't want to be an IT support specialist, it sounds like a boring job to me, but that doesn't mean that there aren't a million career support specialists employed by trillion dollar companies like Apple.

I'm sure people would line up to be paid well to work on Apple's QA even if you wouldn't.
Am I missing something? Dealers always rip you off on trade ins. This isn't unique to Audis or electric vehicles.

Inventories of expensive cars not selling in an economic crisis probably shouldn't be a surprise either.
* Allow new accounts, but hide messages from them until their posts are verified manually and the accounts are either approved or shadow-banned.

* Don't delete ban accounts, don't notify them in any way, but tag their IPs and cookies to auto shadow-ban any sock puppets, so that these don't even make into an approval queue.

* Use heuristics to automate the approval process, e.g. if they looked around prior to registering, or if they took time to fill in the form, etc.

* Add a content filter for messages, including heuristics for an ASCII art as a first post, for example, and shadow-ban based on that.

* Hook it up to StopForumSpam to auto shadow-ban known spammers by email address / IP.

* Optionally, check for people coming from Tor and VPN IP, and act on that.

Basically, make it so that if they spam once, they will need both to change the IP and to clear the cookies to NOT be auto shadow-banned. You'd be surprised how effective this trivial tactic is.

All in all, the point is not to block trolls and tell them about it, but to block them quietly - to discourage and to frustrate.
One of the challenges to building an entirely new kernel is the vast amount of hardware support in the form of drivers and the features the existing kernel exports to userland in the form of syscalls.

Would it be possible for a hypothetical new kernel, presumably written in Rust, to run an existing kernel such as Linux in a VM, just to tap into its drivers and emulate its syscalls? As more drivers are ported to the base kernel, the reliance on the donor kernel would shrink over time.

Edit: This was an aside. Of course I realize that the conference was about adding Rust code to the Linux kernel, and not about rewriting any large, important, and functional codebase in language-of-the-day™. Hence my speculative language: "hypothetical" new kernel, "presumably" written in Rust.
This is a totally different style, but I have recently become a huge fan of James Turrell. There the light is "real" (i.e., it's not captured through photography), but often using naturally produced sunlight along with controlled colored light systems in tandem.

He's also building a massive art piece at Roden Crater. It's a big mind boggling no one has used it for a sci-fi movie yet. If you ever get a chance to see one his skyspaces or his artwork, I highly recommend it. It can be very entrancing and meditative.
I don't think it is any different. Overvaluing the latest hotness is extremely common in the tech industry and is one of my least favorite parts of it.
This is targetted spambots, so they will run through it once by hand and check the request.

Aliexpress uses heavy, extreme amounts of fingerprinting, including port scanning your device and your internal network via <img onerror> tags and Websockets. The slide part is the least of it.
ML/DL is at the exploratory phase for most companies. I have no surprise when seeing this post. Nevertheless, this also open new opportunities in other domains and new kind of business based on data. I have no doubt.
You could whitelist the email providers, and require "strange" email providers to be approved by mods. The workflow would look like this:

1. Sign up with Gmail
2. Verify email
3. Account is instantly approved

1. Sign up with sharklasers
2. Verify email
3. "You're using a weird email provider. Mods will look at your account and see if it looks OK. If so, we'll approve it"
I'm not sure, but aren't they saying that they wouldn't be able to call it "GNU Rust" [1] in the same way they can't call IceCat "GNU Firefox"?

Transgender people care strictly about gender.

I'm generally in support of rust in the kernel, but in the interest of playing devils advocate: Would adding more and more dependence on rust mean that it ties the kernel to a single set of compilers?

I can see why people would be opposed to that.

I'm thinking about LLVM (and, obviously, rustc)

Thank you for this link. A few months ago I stumbled across your paper, Common sense for concurrency and strong paraconsistency using unstratified inference and reflection and found it entirely remarkable. I look forward to reading the new paper you linked.
They were running an old official version which has a serious issue allowing the full node servers it connects to to pop up a message. e.g. "You need to upgrade - click here" - that led to the malware.
Mozilla’s trademark policies have been annoying enough in the past that Debian used to ship a fork with the branding stripped. Hyperbola continued this practice for a while, but stopped for a variety of reasons in the It’s Foss interview, and switched to a UXP-based browser. I’m writing this from a UXP-based browser because I find it much better than Firefox and I dislike Mozilla in general for more than one reason.

But no, there are other reasons outside of trademarks, some technical ones are in submisson’s article.

Don't give a damn about GDP.

Really? Because it's GDP that funds all those government services and social programs.

I'm always confused when people don't give a damn about economics (i.e. during the Covid shutdown debate) when without economics you wouldn't have a functioning society.
Cloudflare perhaps with a firewall rule that blocks bots over a certain threshold? It may fall under fingerprinting if you need to know that.
>each time San Francisco has recovered from the ashes stronger, and those that invested, richer.

I mean that's true for anything, until it doesn't. Not saying that you're claim isn't true in this particular case, but the logic of "BUY THE DIP!" is entirely tautological and more or less just blind faith.

There's no natural law that stops a city from going into terminal decline, there's an exodus, and that's that.
Can you elaborate re: issues and lots of work required? I think it's generally to be expected that non-C language support in the kernel would be hard...
I assume this is in reference to other cars like Model S having a more solid price floor? any reference point on that from people? like bought it for say 80k, and 1 year later sold for X type stories?
This conference talk considered a re-write out-of-scope; they were only discussing how new code could be written in Rust.

Interesting idea, though!
The current major version of PHP is 7 so that makes sense, it was really the jump from 5 to 7 which was a little anomalous.
Thank you for your feedback, I really appreciate it. As attendee you need to create your Viewing Booker account and it is exactly for that purpose of having all your bookings in one place. Say you are going to view 3 different properties, they will all be available in your dashboard, ordered. Also, when booking other viewings, app will check if you have no other bookings overlooping + some spare time for getting from one to another.
This is exactly why I do not want to do captcha. I don't want more third party analytics, tracking, or making our players solve endless captchas.

We are a gaming community that also has some older folk that we'd like to be accomodating for. Most of the cheapo PHP captcha libraries don't support any form of accessibility, or if they do it's a vulnerability that allow instant solving.

Part of the problem is that we can moderate just fine, but we can't moderate or look through hundreds of thousands of new registrations - just need something to somehow get rid of 99% of the garbage automatically.
Empirical analysis of our current society shows that there are divides and power relations along racial, gender and class lines. If you can't acknowledge them, there is no way to fix them. And most importantly, in practice the left reduces the divide.

If you have a better idea of how to fix it, I'm all ears. But fixing a problem without recognizing it exists is, well, not typically accepted as solid practice.

Ask HN: Longterm Remote Work Perspective
Anyone care to share their perspectives on remote work after say 4+ years?

I expect companies to be even more open to remote work in 2021 and beyond.

Personally, I am evaluating if I want to take the plunge, buy a house somewhere nice, but not a major hub and focus on quality of life. I have 3 kids under the age of 10 and it's a big factor for me going forward. Do I really want to spend 2 hours each day commuting?

I have done short stints of remote work in my 15 year career - six months, eighteen months and currently in a six month stint which I expect to stretch to a year at least.

Am curious to see how things have evolved for folks who have been doing this for a while.

- Has there been an increase in remote opportunities?

- Career progression

- Small vs Medium vs Large companies?

- Mental Health

- Work/Life/Family balance

Ask HN: How do I launch a ping-pong ball across my office with Arduino?
I (and my coworkers) have started playing around with arduino.

I want too create a sh*y (simplest) racquet made of plastics, 'glue' it to a strong enough electric motor (servo?) and launch the ball across my office.

I have a servo motor in my starter arduino kit and it's not strong enough. People smarter than me suggested a spring of some kind. Is it possible to do this with just an electro-motor (what kind???) ? I'm willing to pay quite above average amount for components to get this to work with an electro-motor.

How would you launch (repeatedly) a ping-pong ball across an office?

edit: I want to swing my 'racquet' to launch the ball if possible.
Are apps even that relevant anymore?
right now we have way more people than ever before from around the planet being able to communicate in a single language

My father worked in international trading. He would talk (or Telex) with people in 50 different countries each week. He always said, "English is the international language."
This doesn't cover all tractor uses of course, in the Texas Hill Country (think around Austin) there's a pretty large cohort of people (non farmers) that have enough land to necessitate a tractor or bob-cat that will only be used a few times a month.

Imagine being able to "jettison" your battery pack from your classic car EV conversion to plop into your tractor. I know the swappable battery packs failed to take up with the Tesla model, but think about the secondary machines that need occasional power - tractors, ride on lawn mowers, sentimental classic/ hobby vehicle. Things that could be used in series (you won't be moving your lawn and driving your classic car at the same time) that could also benefit as being a power wall.

High class problem for sure, there's a big opportunity to leverage micro-grids + flexible power.
If it's a targeted attack, they'll just make one clean account to check if they're shadowbanned. The rest of the suggestions are great.
Other people in that thread pointed out the OP didn't state why they sold their vehicle, but it shouldn't really be a surprise that a high end Audi lost lots of value in the first year. Take a look at BMW 7 series if you want to see a cliff dive.

That said, used car market has been booming during covid. Sales people commenting in r/cars have said inventories are actually really low on used cars and it's driving the prices way up right now, however that doesn't mean all makes and models will rise with the tide.
The vast majority of the text in that post is inaccurate and hyperbolic. Linux is not "forcing adoption of HDCP" (it's just something Linux has a driver for), Rust does not require internet access to use (and the trademark comments are not particularly accurate either), the Kernel Self Protection Project is alive and well and making new improvements in every new version of the kernel (see Kees Cook's regular blog posts for details), systemd is not spelled "SystemD", gettext has no dependency on Java (and the link in that post explains that). And in general, decisions about what technologies to use are made by those who show up and do the work to build viable solutions, not by people who snark.

It's a rant by an obscure one-developer distribution that formerly used the Linux kernel. Some people are never happy no matter what you do, and if you make the mistake of treating their rants as useful feedback, you get a list of 30 more demands before they'd consider gracing your little project with the honor of their all-important usage again.
In my experience, a lot of open-source systems are managed by terrible teams with their own priorities or ideas, regardless of what the actual community wants.

For example, The GIMP has been notorious for this for its entire history, and it still is[1]. I remember ages ago, the discussion basically went like this.

> "Thanks to The GIMP, people can ditch Photoshop and Windows and move to Linux and an open-source workflow!"

> "But The GIMP doesn't support a lot of features, like CMYK color."

> "Sure, but nobody actually uses CMYK color though."

> "Literally everyone who designs for print uses CMYK color, like print shops, magazine editors, etc., and that's a huge market."

> "Well it's open source, so if it's so important to you then fix it yourself!"

> "But I'm a photographer and magazine editor, not a programmer, so I'm just going to keep paying someone else for software I can use, instead of switching to a free version of something that literally refuses to add the features I need."

Cue tons of Slashdot comments talking about how non-technical people are so rigid-minded that they're not willing to learn anything new and just make excuses instead.

Blender is an exception, not just because it's an open-source success, but because it's managed by a team who are building it for the people who need it, and not just to stick it to closed-source companies by making a pale imitation of a production app, an all-too-common scenario in open-source development.

The e-torn was purported to be the Model X “Killer”. THis is particularly damning considering it’s still eligible for the $10k subsidy the MX is no longer eligible for.

Sorry to hear you're dealing with this. I'm not in the field, but this is a case where I would abstractly be tempted to use javascript blockchain mining or similarly require some amount of useless computation by the browser during signup.

I don't know. Cutting everyone off from human contact so that they face life alone feels fairly existential to me - not in theory, but in practice.
So, then the process itself must be the art and not the end result

I think they're both aspects of the art, as is the feeling they give you. See, for example, the $120,000 banana duct-taped to the wall.
