> Is this basically the return of the thermionic valve after fifty years in the wilderness?

Yes, but with a twist of quantum.

> The experimental data shows that influential operation mechanism is Fowler–Nordheim tunnelling in tungsten and gold devices, while Schottky emission in platinum device.

The bad grammar makes this hard to understand; is FN-tunneling the influential mechanism or an influential mechanism? With the help of Wikipedia I can parse it as an explanation of how the electrons get out of the metal.

When you apply an electric field, there can be a potential barrier: the electron must "climb" up out of the metal but can then "fall" down the externally applied field [1]. With Schottky emission, electrons jump the barrier using their thermal energy; increasing the field lowers the barrier, enhancing the emission. All this comes from the days of thermionic diodes.

But as the field increases, the barrier also gets narrower. And when it is narrow enough, even low-energy electrons can get out via quantum tunnelling[2]. Apparently, this is called Fowler–Nordheim tunneling.

Now these named effects both have equations attached to them, which predict the amount of electrons emitted under different circumstances. But real devices are complicated, and involve both of the above physical effects, plus others. So what researches have to deal with are measured curves that kind-a-sort-a fit the equations if you squint.

The mangled sentence in the abstract makes me think that they have measured something (perhaps current vs.temperature curves) look a bit like the Schottky prediction in platinum, and a bit like the Fowler-Nordheim prediction in gold and tungsten.

Why not hire a customer representative whose main qualification would be diligent attention to detail? You shouldn't have specialized engineers spend their time dealing with issues that are not only one-off, but that also don't require any advanced qualifications. There aren't eight hours a day of check shredding to do, but there is a level of capability between "can only shred checks for eight hours a day," and "spent ten years getting a PhD in computer science."
What part of "anyone can force you to do business with them" sounds like freedom to you? Don't payment vendors and hosting platforms have freedom?

Part of freedom is the responsibility to accept consequences of your actions. If you choose to say such vile things that people quit doing business with you, that's just people exercising their freedom. If you think it's unfair, you are valuing your freedom higher than everyone else's.

When you complain about "deplatforming" you aren't asking for more freedom. You're asking for the freedom of others to be removed.

I do not agree with "Yes it does" (and thus that "Free speech means no one is forced to do business with nazis"), I agree with the rest however (which is basically the same as what dmerfield said).

>There's still a (naive?) liberal side to me that thinks free expression, even of profoundly stupid ideas, might be a net good for society,

I was thinking today about the high costs of the stupid idea of anti-vaccinations, in this case children that are not at fault will die because of this ideas, should we block them or we should put billions of dollars into educating this people instead of using this money for better things.

it is not a black or white problem but in this case I personally think is better to block this idea.

I try and write a tutorial about a subject-chunk - the kind of tutorial that i think would have made sense to me if I'd read it before writing it. you have to suspend the obvious fact that by writing the tutorial you've learnt more and probably wouldn't have understood it at the beginning anyway but let that go for a while.

part of writing the tutorial is exercises - i like a stripped down flash card system. i try and do random-10 as regularly as possible. at the beginning, there's lots of jargon with scripted answers (ie, what is a blah?) but after a while you can move those to the back and you're left with some multi-step questions - over time (because i'm not trying to memorise the answer pattern) i find that i internalise a kind of narrative that uses the concepts/jargon to grope my way to the answer ie, hmmm looks like an aqueous equilibria question, probably need the equilibrium expression (jot that down) and HCl is a strong acid, so i can ignore those two terms and oh look... there's the answer if I just do this and that. Over time, it's the 'groping for an answer' that sticks as a habit of thought and seems to be quite robust. having said all that, i'm craphouse at maths but i'm hoping to get into one day.
Ockam's Developer Experience for IoT Trust: An Overview
The excess creeps in over time, I think, as you develop habits. Quitting cold turkey helps reset everything. It feels liberating to completely disconnect. Once you've been off for a few weeks, a month, then you can set up some boundaries and moderate usage, or maybe you'll discover you're better off without it.
I had a product idea (maybe it is even a business idea) a while back to do shell autocompletion based on an autocompletion engine which was trained across multiple users. Kind of like a cloud-connected fzf.

The problem this solves is that the ecosystem of unix tools is so massive it's impossible to wrap your head around it. Most of us just pick our tools and end up at a local optimum. But with that sort of thing seeing the way other people have solved a problem is very useful.

I still think this would be so useful but the privacy situation is very sketchy. If I could come up with a solution to that I might try to build it.
So what is more personal? Instant messaging? Video chat? Calling?

There are many methods. I actually think what a given person finds as the best contact method varies based on the person's experience and their personal communication style. I like voice-calls and fb book chat best to stay in contact with someone. My point is that writing off any contact method is going write off some people, including some IRL friends as well some potential contacts.

I don't know if there's a solution. Some people are also going to just really dislike a given medium also so the proliferation of communication channels in ways seems to produce stratified groups no matter what one does.
It’s not like that money comes from nowhere.

Flexible problem solvers with attention to detail and solid communications skills are about as expensive as engineers.
Yes but can you run Emacs inside it?
Block social media, people would look up from their cell phones.

People were walking around looking at their cellphones before smartphones or social media took off. They were sending SMS messages. Or playing snake in monochrome. Or would you ban SMS as well? What about phone calls?

Block map sites, people would ask others for directions.

Chronically lonely people aren't going to get any meaningful fix asking strangers for directions.

Block movie streaming sites and people would get to the cinema more often.

Again, if you are lonely and have no friends, going to the cinema is just being in a room full of strangers. People go with their own groups. It's probably more alienating than just chilling out at home because it emphasizes your loneliness.
Yea but it's written in JavaScript.
Can someone explain why the electrodes have to be sharp? Intuitively it feels right, but what is the actual reason?

As far as I can see, the challenge is to get the E-fields (aka voltage gradients) high enough that electrons can easily leave the metal. But for that you need the electrodes close to one another, but they don't have to be sharp.

I suppose if you have too big an area of metal at near-contact, then you will get unwanted capacitance. But is that the only reason?
> then you'd better build your own Internet. Because this one is fresh out of freedom

Nobody stole your freedom. People just don't want to interact with you. That is okay though, it is their right to elect to avoid interaction.

Why not just mail out a DVD of all these wacko videos to subscribers instead?

Back when 9/11 conspiracies were still quasi-mainstream, somebody in our neighborhood went door to door and gave every house a copy of Loose Change.
Think of it like having your food brand be in the supermarket. Sure you can open your own stand alone stores but then you have to build and manage that infrastructure yourself, and your audience is a very small fraction of the traffic the supermarket gets. Practically no one sees your product without even more overhead in advertising and marketing.

“Boden is written in modern C++11 to make development easy...”

They lost me there. I admit I haven’t done any true C++ in the last few years, bowing at the height of Boost. So I’m curious, did I miss something in the next chapter of “modern” or perhaps the “11” that suddenly made C++ development “easy”?? It was quite capable for sure, but easy, no. Honestly curious. Maybe I’m just not a good enough developer. :/

People ate those foods far less often because grocery prices were a tiny fraction of fast food prices. There were even intermittent price wars between competing grocery stores.

Now the Savemart-Kroger duopoly means fast food and groceries have reached esentialy the same price point.

I'm not settled on whether I consider this idea good or bad. Probably a mixed bag. But these points are critical. It MUST be handled very carefully to avoid being a really bad thing. Like, up front contract giving you 3-6 months to move after end of employment (no matter the cause). Even better, have some portion of the lots be empty with hookups, for employees to park their own mobile home or RV.

I've been developing an opinion lately that what we need is fewer roundups and "objective" reporting and more opinionated here's the end-to-end stack I use and I think is good and here are the tradeoffs. With a diversity of stacks and opinions, this represents most of the roads you can go down and lets you pick the person whose approach or philosophy most closely aligns with yours.

You also often get UI automation. I hate the trend to not use the built-in widgets. I am talking you, Microsoft...
Rather like email, you filter out the noise, you decide what you're going to consume that day, and you ignore everything else.

This is how I use Facebook. I basically only use it because it's a convenient messaging service; Hell will serve chilled water before my non-tech friends and family join Yet Another Messaging Service™, so I meet them where they already are.

Plus, for better or worse, I rather like the Facebook Messenger interface and app. It's not perfect, but it's nice looking and consistent across platforms. If it weren't for most people I know being on Facebook and not everybody having Apple devices, I'd probably use LINE or stick to iMessage.
What about those rumored thousands who are graduating with "unemployable degrees?" If the market for capable individuals was the same as the market for specialized knowledge then STEM would not be so much more economically attractive to students.

Linuxbrew, like Homebrew, is useful for non-invasive non-system/infrastructure packages. Compared to system package managers, it is (arguably) simpler to use and contribute to, and often has more up-to-date packages (especially compared to e.g. RHEL) because it tries to solve a much simpler problem. I think there is room for a package manager that focuses more on managing your user-specific CLI tools than your system libraries.

I don't like macOS all that much, but Homebrew is really good.

I don't subscribe to your view. We each receive different lots in life, some with more options and better support networks than others. Being poor is not an enviable position, and it's only fair that everyone contributes according to their abilities.

To me, having a considerable part of citizenry receiving rather than contributing doesn't sound like a taxation issue, but rather income inequality issue. Having more equal income distribution would automatically mean more equal tax base. It's hard to achieve through legislation though, so the second best option seems to be a heavily progressive taxation. I think it could even be worth it to emphasize that even more -- perhaps to tax capital income like regular wages, and negative tax rates for the lowest income brackets to encourage working?

Finally, lots of Finnish citizens are obviously currently net receivers from the state. Unemployment, health problems, or troubled upbringing combined with strong safety nets do mean that there may be considerable costs to be borne by others. I know I'm one of the luckier ones, and very happy to pay taxes knowing they contribute to a fairer society where everyone has a realistic chance to go as far as their capabilities allow.
If your argument is that someone will willfully discontinue contact with you because they restrict themselves to only one form of communication, well that doesn't sound like someone worth having. That sounds like toxic behavior and manipulation. And over such a petty thing too.

I don't buy it.
Well, in the case of Dungeon and Dragons, you have an activity which has similarities to a fully structured activity like a hobby group but also similarities to an entirely unstructured activity like friends, acquaintances or strangers "hanging out" in a given space. (All of the library meeting policies I've ever looked at would prevent a D&D or similarly informally social group from meeting there btw, though other places, like restaurants do allow them).

Today, you have a vast variety of ways to explore any given hobby and yet you have an "epidemic of loneliness". My view is that this comes because lot of people don't actually have strong "special interests". You can see something like meetup with fairly vague activities informal, non-athletic hikes get lots of interest. Dungeons and Dragon in particular is nice because it doesn't require people to become experts or masters of any given field, there's no winners and so it's like a lot of specialized fields. But it still only appeals to some people. For a lot of people, the real lack is public space that isn't structured and I don't see library meeting rooms really helping there.
I hate non-discoverable UI's. The first thing I do with any software, is click through all possible menu's, windows, ribbons, whatever. After some time, I usually get quite a grasp on what the software is capable of. The two notable exceptions are textbased UI's (terminals, dsls, ...) and softwar requiring domain specific knowledge (e.g. geomodeling software, specific 3D modeling software, ...).

I never understood the appeal for terminals. Often (Microsoft's Powershell is a notable exception) the syntax is full of incomprehensible abbreviations, the syntax is wildly inconsistent, the syntax contains hard to remember acronyms...

No, for me, terminals and most textbased interfaces will never be as usable as GUIs.
Do you support the freedom to deplatform practicing Jews as well ?
Yes, C++11 added Smart Pointers and Lambdas, which made development a lot easier, among other stuff.
This makes a lot of sense because most of us aren't going to work with a different company for each and every part of our infrastructure. If it's super critical it be the best, I'm going to seek out the right tool for the job. If I just need to have something, at a basic level, I'd rather work with a company I already work with.
Error margins? There's a lot more room for error with a flat surface. I'm not sure if that level of precision is at all important, but it's my best guess.
I like money as much as the next person, but your statement could perhaps stop at "Capitalist are motivated with making money" and still be mostly true. The other parts are optional.

The function of government is to make sure those other parts happen - that the capitalist doesn't take the money and not provide the goods (the courts, the police) or provide goods in one place at a low price by dumping toxic shit in another hurting people (EPA), tell you lies and get you to invest in their firm (SEC) or a million other examples. The burden in burdensome regulations is in the eye of the beholder.

Also remember that (at least in a democracy) we are the government. If you don't like what they're doing, vote the bums out. It's a little harder to vote out the plutocrats.
Still sounds expensive. You can take a train + bus/tram/subway from Waterloo to central Brussels for about $125/month. A bus pass in Luxembourg to the city center costs like $30/month. Lisbon will cap all public transport passes (even multi-modal) to $50/month, or $100/month for a whole family.
What really makes coding environment productive for me are: file navigation,
code browsing, call hierarchy, class hierarchy, find usages, find declaration,
find implementations, refactoring, build integration, debugger integration,
documentation integration.

I did try vim more than once over the years. I'd use it to edit config files on servers but would much prefer an IDE for coding.
I don't understand what you mean by this being a genetic map, this seems like an unrelated concept: https://en.wikipedia.org/wiki/Gene_mapping

This article is definitely about the potential to sequence people's genomes for $100. Part of the confusion may be that a process called mapping is a necessary step to figure out where each of the hundreds of millions of ~200 nucleotide reads for a genome came from - you "map" them back to the human reference genome for comparison.

I was told this may have been because older browsers limited the number of simultaneous connections to a domain name and you could work around it by having multiple domain names.
I miss the instant-on, straight-to-REPL, ~1 second reset features of my old Commodore 128.

And I am not kidding in the least when I say that. Regarding more modern operating systems, BeOS was so nice to use. Here was an OS that had UI/single-user needs baked in to it from the beginning, and it was a breath of fresh air. I'd liken it to the experience I had switching from a 60Hz monitor to a 164Hz one- I didn't really think about it much at the time, other than I wanted a gsync-capable display, and one was one sale. But the smoothness of the scrolling, mouse use, etc was so much more pleasant. And yet I never would have complained about the 60Hz screen until shown the alternative.

Venturing in to personal opinion, I'd also say BeOS was developed at the inflection point between engineering running the show, UI be damned, and where we are now, with designers running the show, actual capability be damned. It was a good mix.
You could also learn screen instead of minicom. screen supports communication over serial.

> I cannot believe how many comments hostile to free speech are on this thread

It's almost like what is being discussed has nothing to do with free speech. BitChute didn't have its free speech rights harmed in any way. No jack booted government thugs pointed their guns at the owners faces and told them to unplug from the internet.

All that happened is their current payment provider determined that their business relationship wasn't profitable and terminated the business relationship. BitChute is free to find another way to seek payment.
Plus most FOSS software is being developed by volunteers for free without the resources to fight back.

I don’t know of any reputable company that would take the risk of using open source software in a way that was against its license.

Nevertheless, though unlikely, even if copyright stopped existing it does not mean that there could not be a replacement that only protects FOSS projects.

You really trust lawmakers to have both the will and the knowledge to do that?
C++11 is old now, C++17 is the latest version which is pretty awesome. It is a serious undertaking just getting packages linked on a platform like windows. I took a short detour into golang, that was a few months ago; C++20 promises package management via modules instead of the old include system, all the c++ compiler vendors are working on it right now. Until then, i'll stick with go.
