Well, every material in column IV of the periodic table (Carbon, Silicon...) is a semiconductor. You basically want to have enough electrons, but not too much.

Electron density can be adjusted by adding atoms that have too many (column V, on the right), or too few (column III, on the left). Hence III-V semiconductors, like GaAs. You'll notice that Germanium is used as well in some applications (fast, expensive circuits for high frequency applications such as RF).

By combining those together, you can obtain a range of properties. I think phosphorus was already used, but the insight here is probably that it is 2D.

The way MOS transistors work is that you have a semiconductor that is really just a bad conductor (so it could be made starting from most conductors, "doping" them to conduct less with atoms that trap electrons). By putting an electric field across the semiconductor, electrons will gather together near the positive electrode. Electron density is now enough to meaningfully conduct. So "semiconductor" is just walking a fine line between conducting and not conducting :)
I think it's fine to have cameras in a shop or in a bank or whatever the virtual equivalent becomes because they serve a clear security purpose.

The problem with not end to end encrypting private communications is during a lockdown people now have nowhere they can go for a private conversation. If you invite someone over to your house for drinks or for dinner you feel you can talk freely because the government doesn't have cameras in your house, that would be an invasion of privacy. Where is the virtual equivalent of that once zoom is not longer private?

Remember your freedom will be taken an inch at a time. Not all at once.
Simply put, startups don't have the budget to match higher salaries.

I did a startup setting aside a large portion of shares for employees, but nobody asked for it. It was easier to just pay more - large businesses were paying $1000/month for an mid level programmer. So it was just easier to offer $1000/month to juniors.

However early stage VCs offered a rate of about 1% for 2 months salary. So sometimes it's easier to offer that early stage employee the 1%. Some have enough money in the bank that they'd like to invest in something.
This is asking about P2P Matrix, where typically there isn’t a server involved. The transport layer security runs between the peers, effectively providing a form of end to end encryption if there are no nodes in the middle.
Graphics drivers and WiFi drivers never worked without significant pampering for me in Ubuntu, and I've been using Linux for 15 years. Just last week I updated my working Nvidia drivers for my RTX 2070 card via Ubuntus GUI and lo and behold after restart the screen is just black. It's at a point where I just want it to get a working system and never update it, security and performance be damned.

I know how to fix it because this has happened with pretty much all graphic cards I've had, I'll have to go into and mess with the grub config, make it run in safe mode, restart, try another grub config, restart, find out it doesn't work, run safe mode and reinstall the old drivers, cross my finger and wonder where my Saturday went.

Gentoo was the most reliant by a long shot (maybe for the simple reason it always asked if it should replace my config), but that is a time sink in whole other league.

Have heard good things about Fedora lately, but I dread throwing away the Debian knowledge I amassed.
Just using population density doesn't give the full picture. Copenhagen metro area has a population of 2 million, while Malmös metro area is around 700k

In practice this means that
Copenhagens busiest train station (Nørreport) serves (in non-pandemic times) 165k passengers a day while Malmo Central Station serves 46k passengers daily. Which gives a much better picture of the kind of density that would make a virus spread easier

I actually went in the oposite direction: I started with C++ and Java. Until I had the opportunity to work with a very interesting team using Smalltalk (this was in 2004, so St was not popular anymore, but I liked the team and it was an opportunity to learn).

The article is very good describing what failed, from business to technology.

Why people jumped from St to Java? Besides the licenses and the OS movement that took many St companies off guard, there were also technical issues:

- Java was better for server side work. It had mature frameworks for Http/XML/Database access. Big companies allocated tons of resources to create Java frameworks and tools... the situation for St was different, you were at your own. For example, I had to debug and fix the WebServices framework available in VisualAge... because I didn’t have another choice.

- The JVM was superior in many areas: native threads, different GC algorithms, JIT, and many tools for monitoring and troubleshooting. Most of the St VMs only had green threads, it means that any blocking native libraries (like DB drivers) are problematic.

- As the article says, enterprises moved from desk apps to the web. And web frameworks for St arrived late.

- The classic St-80 was not designed with the idea of packages in mind. Loading a package is basically executing code that modifies your image. It’s powerful, but problematic because it can introduce unexpected bugs. Strongtalk tried to fix that, but it was a research project.

- To the package isolation problem, add the fragmentation between St implementations... it didn’t help to create an open source ecosystem of shared libs like in Java.

What I miss?
The environment!
In St you have absolute control of the environment. You can inspect everything (including your editing tools), and evaluate code everywhere without having to stop the world. Today you have editors or IDEs with plugin APIs, but is not the same. A comparable experience is modifying things live in the web browser, but it lacks the inspection/authoring tools from St.
> Germany has an issue with criminal clans from the Middle East, our law enforcement system isn't equipped to deal with them and our laws in general aren't either.

There is a big disconnect between the crime statistics in Germany, that show low crime levels by international standards and recent reductions in crime levels, and what the German public believe about the prevalence of crime in Germany due to alarmist tabloid reporting.

Cf. e.g., https://www.dw.com/en/crime-in-germany-drops-10-percent-in-2...

Indian app that deleted Chinese apps from Androids deleted from Play Store
The QQ group is interesting. I attempted to use QQ recently but was banned everytime. My use was legitimate I needed help from a Chinese engineer to support an industrial automation line he built but couldn't install due to Covid. I assumed that I wasn't supposed to use QQ outside of China. Seeing it here makes me question that. It may have been that the engineer I was contacting was in the middle of Wuhan.
I suspect when there is very cheap electricity, income is much higher than the electricity costs, and money is ploughed into new hardware.

When electricity is expensive, it's still worth running the most of the equipment you already own, but it isn't worth buying more.

Hence, you wouldn't expect much seasonal variation in hashrate.
Nice work! Can you tell us a bit about your tech stack?

The simple answer, once again, is we choose our experts based on evidence.

By default, the experts in any particular area are the people who have proven they are (based on evidence of education and work experience). The fun fact is, anyone can challenge an expert opinion. Just present compelling evidence that supports your claim.

It's okay to have alternate opinions, but don't try and argue they are valid just because you "chose" a different "expert" to believe. Present evidence or GTFO.

Please, go troll someone else with your circular reasoning nonsense. You're not being insightful or intellectual, you're being childish.
They do, but they put black tape on the numbers or conveniently have some piece of equipment in front of it. It's not like someone is going to punish them for doing that

Problem is you can't just extrapolate Sweden to other countries ... UK for example has higher levels of obesity and Type II diabetes, which are both known prognostic indicators for a worse outcome.

They also have a better-funded health system than the UK and lower population density.
It's trivial to find "random fun mattress facts" by Googling for exactly that, but thanks to link and content aggregators, instead of flipping through channels on the tee-vee, we scroll for miles with our thumbs. Before commercial interests took over the web, it was full of weird and wonderful sites by hobby enthusiasts, built in their spare time that would have random weird facts and stories. For better or worse, that Internet is behind us now, so it's rare to come across that sort of treasure trove of a site. (To be clear, there's better and worse today, compared to the Internet of yore.)

What's the case here, is that mattress store owners, in the conversion to online sales, have purchased, not only the adword for "mattress", but paid for all manner of SEO tricks and hackery in order to drive their site to the top of the results. Far in excess of what a hobbyist could or would bother with.

It's a long shot, but the long tail of the Internet says that this has happened at least once. Someone was just poking around came across a random mattress myth or fact page, and found out that something they hate about their mattress isn't something they have to put up with. Whether that's "being tricked" into buying a mattress they didn't need, I won't say, but it still tickles an intellectually curious itch that I didn't even know I had, to find out that it’s illegal to purchase a mattress on Sundays in Washington.

A single word query like "mattress" is vague and starting from first principles, we live under capitalism, assume everyone's trying to sell you something, and a search for "mattress" proves to be no exception. Same goes for if you search for "windows". Second link is how to get it (for $199).
Doesn't the hashrate need to stay high for security reasons? If miner participation is low, can't bad actors dominate the system and produce false transaction?

If the hashrate ever collapses isn't the whole system at risk?
No but then I've never passed a counterfeit nor robbed a woman at gunpoint in her home either. Also as I pointed out elsewhere the risk of death a person of color by the hand a black or Hispanic cop is at least as great as by a white policeman
I think that's perfectly good logic. It's just that the general theme has already had major discussion on HN, including on the front page when you posted this. The distinction between "police brutality" and "police riot" is without a difference; the internet does not do subtlety.

Using more energy isn’t bad. It will drive efficiency improvements such as achieving a higher PUE via liquid cooling
This is the same Pao who talked about "incels".

And that is the problem in a nutshell. The people who portray themselves as good (often for monetary gain) are so vicious that they provoke a counter reaction.

Previously leftists (or limousine leftists) fighting for something attacked politicians and institutions.

Now they attack regular people directly online and also offline -- Hillary Clinton's "basket of deplorables" was unheard of in earlier times.

What you see in the right is a backlash. I wonder if some left hard liners (perhaps unbeknownst to themselves) are planted and financed by the right as agent provocateurs.

They seem like sensible policy positions for reducing violence and misconduct by police.
In NYC, many looters are coming down from their residences in Harlem and the Bronx, many brazenly by car, often with fake or covered plates, and raiding stores in Manhattan, Brooklyn, and Queens. There is no logistical targeting of large corporate properties. Everything from the corner store to local eateries is being smashed, grabbed, and burned. Many local store owners had their safes stolen.

The looters are motivated by selfish greed and clearly have an affinity for the most expensive commodities ie. Nike, Apple, Gucci, Louis Vuitton, and Rolex. But they still aren't surgically striking - the picture you falsely paint.

Many are even dumb enough to indiscriminantly destroy their own local neighborhoods, targeting both small and large businesses.[1,2]

Now, why would any outside investor, or even a poor entrepreneur who lives in the area, invest in the area, knowing that this infantile us vs them, poor vs businesses is going to be dominant narrative and zeitgeist of that area's people?

Investors wont take the same chances again if they are unappreciatively and scornfully seen as "rich man building a starbucks where it doesn't belong."

The people from these areas claim they want prosperity but deface and burn down anything with a mediocrum of betterment. By process of elimination, they want a poor uninvested area. Their message rang loud and clear in the last week: do not build nice things because then you are a "no-face corporate capitalist."

I am not sure I buy it, but it has a slight air of plausibility. Certainly, many Germans knew what was coming. Many soldiers made great efforts to surrender to the West rather than to the Russians; German refugees flowed westward; and so on.
It is sad that "heat" and "efficiency" are defined like this...

Police is actively avoiding helping victims of lootings. Helps to discredit the protests and US police NEVER have an interest in helping anyways.

Just from personal experience in ca. 2012, the Binghamton, NY PD has openly threatened to plant drugs on us following a a noise complaint.

We talked to officers trying to cooperate but as we weren't following ORDERS such as "Don't scratch your arm right now!" the cops escalated and one took out a tazer. We were all white btw. and as a European I couldn't believe those cops. We calmly talked and suddenly we face a tazer? Because those authoritarian scumbags didn't want to hold a conversation with the people THEY confronted? Over a noise complaint?

Something is super wrong in the US when it comes to police. Maybe start educating them before letting them lose on society. It helps.
'Acme' might very well be the worst name for any project. I am guessing it makes searching for anything about it through a search engine next to impossible.

I can see that. Still there are such cases. Monopoly on the approval process is bad anyway. Even if acting in good faith, mistakes happen.

Clicking away the dialogue should never trigger the update. It's the opposite of what the whole UI of Windows has always worked like.

I guess it’s all about choice of hardware now. If you use components designed to support Linux life will be pretty smooth. I’m sure someone will point out the nvidia has a reputation for being linux hostile which does limit your choice a bit.

Wayland, Gnome and Firefox are working together very nicely.

Mixed HiDPI with standard seems to be solved now. I’ve seen the odd glitch where an app gets confused as you move from one screen to another but overall very good.

Trackpad latency is improving but still not quite perfect. The fact that it’s close and constantly improving though makes me very positive about using Linux in place of my MBP full time.

I actually miss the Gnome window management shortcuts when I move back to my Mac.
Blaming the mass transport system is an other theory being used to explain why the region of Stockholm has a much higher per capita deaths than other regions. Stockholm has the only subway in Sweden, and it is speculated that elderly care workers are heavy users of it in order to operate multiple care homes from a central organization using employees that goes from one home to the next. In almost every other city in Sweden they tend to go by car.

But this again points towards the kind of restrictions that would be effecting in reducing the number of deaths. Stopping the subway, get people that work with risk groups to not be in places where there is a high risk of infections. Malmö in comparison has significant less movement within the city and people use the mass transport system a lot less. In practice there are buses and taxi, and not much else. A common remark is that Malmö is actually 4 smaller cities of different social status with very little intermingling.

One effective restrictions that some nations like Finland did early was to lock down the capital and impose significant restrictions locally in those regions. Treating people different within a country based on where they live is very unpopular, but as a strategy to prevent deaths it seems like something Sweden should have done. Again, it is not restrictions for "visit restaurants, go shopping, attend gyms and send children under 16 to school" that seems to be relevant takeaway from the data.

Handheld UV Light Devices That Kill Covid-19, Viruses May Be as Common as Phones
I think you are wrong. The reason is, people seem to continue extrapolating reasonable privacy laws that were originally meant for the physical world to the virtual world. In the physical world, however, there's always reasonable workarounds to break into these privacy barriers if there's a suspicion of crime. In the virtual world, often, there's no possible way to break strong encryption barriers even if everyone agrees there needs to be a check on what's inside for the public good.

As an illustration, if we get reasonable evidence suggesting that someone is growing marijuana in their ranch, we can get a warrant and go inside. There's not too much the owner can do to stop it. However a perfectly encrypted iphone cannot be broken into, no matter if the entire world agrees that there's evidence of crime in it.

From what I can see, no one argues against warranted search of personal property in the physical world, except maybe some sovereign citizen crazies. Given this, why can't we strive for a similar system on the virtual world as well? I too agree warrantless or unfettered govt surveillance of technology is bad, but that's a policy failing not a technology one. We should try to focus on how we can hold governments responsible instead of making fully protected crime caves for anyone who cannot whip up a conscience.

I agree privacy should be a right, but not at the expense of many people enduring a life of hell in these cordoned spaces for that cause.
