That's actually exactly what existing MCF machines do. The gyrotron (ECRH, same as a microwave's magnetron) resonant frequency is tuned to the confinement field strength of the plasma so it absorbs the energy. On top of that there's a vacuum so air doesn't pull all the heat away and a magnetic bottle so the plasma doesn't touch the wall. Fusion is very far away from happening spontaneously on Earth.
It does, and you can see at the end of his list a tapering of the growth. US energy consumption has grown 1% in the last 10 years, not 1% per year, 1% in total. Now sure, some of that is offset by some shift to imports (energy is expended in China, for the benefit of the US), but not all of it.

However had energy use increased at 2.9% since 1990 it would be nearly twice as high as it really is (4.2GToe vs 2.3 in 2018)

The Earth as a whole, with rapidly industrialising countries like China and India, global energy use from 1990 to 2018 only increased about 1.5% per year.

The world is becoming more efficient, and ultimately there is a limit to consumerism - I personally use less energy today than I did 20 years ago, and I'm sure that's the same for many people in the west. As transport becomes more efficient, there's only so many times you can go on a plane in a year (144 was my own record, but lets say it's 1000), after that point energy use on airplanes can't increase - there just aren't enough hours in the day.
A fusion reactor would have at least a thousand tons of molten lithium coursing through miles of plumbing, that if breached explodes and burns uncontrollably; and the reaction product dissolves mucus membranes.

>many computer enthusiasts who do not like Macs, so they’ve gone into denial, like Fox News cultists and climate change

Fuck this guy. Wish I can flag this multiple times into the oblivion. I don't like Macs because they are locked down both on software and hardware. It's not a "personal" computer. Literally have to dance around Apple's limitation all the time if you want to use something not approved by the high and almighty.

If you want to live a walled garden so be it. But don't call people "Fox News cultists and climate change deniers" just because they want to use something else.
Large parts of the Earth surface were generally uncomfortable in 1850, so that's not really a useful statement.

No, it's a B2B thing. Consumers don't pay for it.

Think robopilot software. It needs to be put into a plane before consumers can use it.
I feel like I must be missing something but in the part about the relativity of simultaneity [0] I feel like this is more about the relativity of the observers and the limitations of speed of light than it is about the ontology of time itself?

The definition of "now" as when the light hits the mirror on each side is a "constructed" now, a false now if you may. It takes the light longer on the right side than the left side because she is moving through space, all that tells me is that there is no way to communicate a "now" between different observers because there can't be instantaneous communication between observers, not that time itself is relative or physical stuff itself doesn't have a constant time?

She says in the video that we have to find a way to operationalize how to find a now, to measure it empirically but maybe that's not possible without running a complete simulation after the fact.
But to me it seems not surprising that without instantaneous communication there is no way to create a "now" empirically but that doesn't mean it extends to the ontology of physical stuff itself or time itself. There would still be a time in there (you should be able to see it in a simulation?)

Also for example, if you use sound instead of light, if I'm far away from a sound source (farther than the speed of sound), and another observer is closer to it, we would not be able to use the sound source as a source "now", because I would hear it later. Is this the same type of situation or different? I feel like I must be missing something fundamental here but I'm sort of going out on a limb so please don't slaughter me :P

Oh, you see it. The things you've seen just weren't together, where it was easy to connect the dots.

Consider the tanks. ① You've seen that Russia is losing tanks in painful numbers, you've seen that so much that you believe it. ② You also believe that the of of the purposes of sanctions is to diminish Russia's ability to produce new tanks and similar weaponry. You may not know what exactly all of the purposes are, but you believe that to be a purpose. ③ You've seen that Russia is taking sixty-year old tanks out of storage, and you haven't read anything about boosting production of new-model tanks.

And you've seen that the ruble is very strong. Some people present that as a boost for the economy, but it's more of a violent shake. Exporters have their income incease drastically, importers have their costs increase equally drastically, both have difficult new non-tariff barriers. This may be described as "encouraging innovation" or perhaps better "innovate or die!!!1!"

Not included in this list but definitely worth mentioning;

- Lowering your hiring bar. When you hire people the burden to get them up to speed and productive is on the existing team. If these people are smart and motivated, great! But no-one benefits from having 200k+ engineers now have to spent their days explaining how GIT (yes, really...) works to a small army of juniors.

- Not involving your current team in decisions that affect them. Re-shuffle the teams around, re-architect the product, change the existing workflow, etc. If you hire professionals with 10-20+ years of experience just to ignore their advice, they're going to be looking for an employer that does appreciate their input very quickly. Nothing is more frustrating than telling a manager not to put his hand in a pan of boiling water, just to see him do it and then blame the cooks for having a pot of boiling water around :)

My current manager decided to add 50 outsourced engineers to a team of 5 to deliver the product in a year (instead of the 1.5 - 2 originally guesstimated).

In addition to this he decided to give the responsibility for the architecture of the application to outsourced "solution architects" with no domain knowledge and reorganized the teams to split them by job title (e.g testers, developers, operations, "management", etc).

Current productivity is lower with 55 than it was with 5, 3 out of 5 have already handed in their resignation. We're burning through an additional 3 million this year with 2 crappy React pages to show for it.

Next year the damage will probably be worse given the rapid outflow of talent.
In the same boat. It's painful, whenever a bug appears or there's something they don't understand; boom! A meeting gets scheduled. It kills the soul nevermind productivity.
The other one is having to answer the same questions over and over.

When you're about to go to production, tests have been written and everyone's done their part, you'll get asked, "so you're sure nothing will break production?" It blows my mind.

>How are the TSPU boxes setup? Are these provided by the government to different datacenters/IXs or at some sort of higher level than that?

They are provided by the government and should be installed topologically close to the client, before CGNAT. This is a modified RDP.RU EcoFilter, and currently are required to be installed only on residential connections, not in DCs/IXes. ISPs do not have any configuration access, and it's prohibited to route traffic not via the boxes. The abbreviation TSPU means Technical Measures to Combat Threats, and these boxes are capable of collecting, saving and centralized sharing of NetFlow data, but currently are almost always used only for blocking, however the general idea is to centrally control BGP flows and collect SNMP data from other ISP routers.

The company which controls the boxes is called Center of Public Network Monitoring and Control (ЦМУ ССОП, Центр мониторинга и управления сетью связи общего пользования).

>do they also filter the semi-public, known blacklist?

Yes, they do. I suppose the idea is to replace filtering DPI boxes which were installed on the ISP network all these years with this one. Right now most ISPs have both TSPU and one of commercial DPI systems.

To me, this article reads like one where there is an elephant in the room and it is not being identified. And I don't think the article can give enough of the rich detail of what is going on in Haiti to give us useful clues about what the elephant is.

But those satellite photos look like the North-South Korea divide, and that is due mainly to unworkable political philosophies in the North. So I lean towards assuming ineffective leadership philosophies here too. There are some hints of that in the article, but not enough to draw conclusions.
I'm surprised Ethiopia is that low down on the human development index. Addis Ababa seemed pretty developed compared to places I've been to in Texas.
Before the independence wars, all modern stuff reached our colonies before they were even an idea in Lisbon.

After the independence and continuous wars, mostly sponsored by western countries, they keep a shadow of their former selves.

I have been a couple of times in African countries and it is quite sad to see how hard it is to come out of this vicious circle.

I also find tragic that in some countries despite being independent, the colonization for all practical effects never left, because most companies that offer jobs worth having, are in the hands of European/US multinationals or expats.

> In my opinion, Have a minimum team size of six.

So I guess this post is only for big companies and VC-funded startups. I'm the technical cofounder of a tiny bootstrapped company, and for now, I'm the only engineer. Being the sole engineer is stressful, but it's currently necessary, and I think it's worthwhile to maintain the control and integrity that we'd probably have to give up if we pursued the funding to hire a bigger team. Even when we do have the revenue to hire, we will certainly not go straight to a team of 6 or more engineers. Big teams have their own problems, like communication overhead.

Searches during twilight toward the Sun find several asteroids near Venus’ orbit
For any two points in the event space (spacetime), which are causally disconnected (space-like separated, which means one point is not in the light cone of the other), there is always an observer that perceives them simultaneously. There are also observers for which one point precedes the other and vice versa. There are observers that can't see (or cause) one of the points, or both.
Is this an actual problem, though? It seems like not even Google deals well with these types of pages.

Often those types of pages are difficult to link to as well, as they're often highly stateful, applications rather than documents, and what you're seeing may not be what you get when you click the link. Not really what you want in a search engine.
In the beginning, of course.

Nevertheless, the heating of the Earth puts a limit on the total usable nuclear power on Earth, both fission and fusion, it cannot be "infinite", but it must remain forever a small fraction of the power of the incoming Solar radiation, otherwise it would cause an excessive heating of the Earth by itself.
That's nothing. I once read an actual story on a US aggregator site.

I lived for over thirty years in the United States, but mostly stopped biking there. Now I bike everywhere.

I agree with everything you say but you're missing a key point - the active hostility that a significant number of drivers have for bikes.

I biked in Canada for ten years, and drivers there (at the time) were mostly indifferent to bikes.

(And yet I say this, and then I remember that one of Canada's rising bike stars at the time was permanently paralyzed by a driver who had repeated tried to force him off the road before (in his small community) and who had been reported to the police many times for it, and yet suffered no penalty other than a temporary license suspension. This was in the early 80s, and I haven't thought about it in 30 years, but I still feel a rush of rage.)

Now I live in the Netherlands, and cars are actively solicitous of bikes. Let me tell you that the center of Amsterdam has a lot of cobblestone streets with no separation between bikes and cars, not even a line on the street, but (nearly all) the cars treat cyclists as if they are delicate and breakable, which is actually the case.
3.2. Erotic Component

Several, but not all subjects wrote they feel an erotic component as e.g.:

“In puberty there came an additional sexual component of about 50% weight.”; “In addition the stump is erotic.”;

“When my first wife suffered from an osteo-sarcoma and lost her left leg, my life was perfect. The stump became part of our sexual satisfaction.”;

“There is an aesthetic sexual complex, in addition I find the kind of walking very erotic.”;

“The otherness, the stump stimulated me. Pretending always resulted in masturbation”
I'm struggling to understand how your example is not just something any language with error types can do trivially.

Every explanation of conditions and restarts I can find explicitly mentions searching the call stack for a handler and jumping into it, then reserving the capability to return to the function the error originated in.

This is explicitly non-local and hidden control flow (ie. the much maligned goto of exceptions).

The only advantage I can see asserted of having handlers (exceptions or conditions) that way is that you don't have to look for the error and pass it up manually but ! does that anyway so it doesn't seem worth throwing out your ability to reason about invariants in the context of a language with mutability and such.

Then there's returning to the stack frame you started in (the part I somewhat unfairly called comefrom). You need to drag around all the machinery required for continuations in order to do this. If the goal is to have available some of the context of an outer stack frame, you could pass the relevant references down and just handle it where you wished to resume.

Further thoughts: In some ways errdefer is the polar opposote of this concept. It allows the function to clean up and preserve invariants whilst passing control up the call chain.
Huh, that's pretty expensive. For comparison, my search engine has an operational cost of ~$50/mo.

Either don’t take notes and read more, in clusters by topic, or write about what you read. You’ll still forget a lot but at least you’ll be able to find out what you thought about something at the time. Or you could use Anki or another spaced repetition system.

This can only be an individual question. Try things.
Unsurprisingly Rust can target Morello already but it comes at a performance penalty. Whereas C has myriad integer types for special purposes, Rust only has a pair - a signed and unsigned integer of the same size as pointers. Since on CHERI a pointer is a different size from an address, Rust pays the price of using a 128-bit integer (to store pointers) as its array index.

The potential change would make these types address-sized, so you can't fit a whole pointer in them on Morello where the pointer isn't just an address. On other platforms this change makes no practical difference.

Agree with most points but one which is making a manager do coding/shipping.

Most of IT managers I met possessed no real IT skills. They wrapped their heads around only as much theory as needed to _manage_. Most of them did not came from engineering world but from business one.

Ideally, manager should be able to do the work their team is doing, but reality is quite different. I stopped expecting managers to understand what I do outside of expected effects.

Regarding estimates, it really is frustrating when a non-technical manager cannot understand the inability to state any reasonable time estimation.

- no idea, haven't done anything like that in the past

- ok, so how long?
Telecoms are privatized
There are a lot of places that have a really nice major city that gets foreign investment and stays under the watchful eye of the government. Other places, particularly rural, fall to the wayside. The US has a lot of interest in catering to rural/suburban voters, sometimes more so than they do cities.
Which is why public transportation needs heavy investment now.

It is much better for 80% of the people living today and 100% of the people living 50 years from now who will be dealing with the devastation caused by our CO2 emissions.
Agree on some points (first 3 for sure), disagree on others.

A major missing one is the demoralizing effect of having to work with incompetent team members, with management unwilling or unable to do anything about it.

An incompetent person is likely not a bad person - more likely a good person who is the wrong position, or who just isn't capable.

I recall working on a team where I was called over by one of the members to help out. I was new on the team, and wondered what the sidelong looks from other team members were about. She wanted to know why her program did not run. I asked to see the compiler output. She asked what a compiler was. How a person could attain a masters degree without actually knowing that is beyond me, but her skillset clearly had nothing to do with software.

This was in a government agency, so she was promoted to management where she became one of those other problems on the list.

Scrum cargo culting whatever amazon is doing seem to work very well towards this end
The previous big bank I worked at did this all, they had an agile coach and multiple scrum masters. The agile coach would essentially sell agile to management, and then blame development teams for not delivering what he sold. Building a product almost became irrelevant.

We seriously had a full day of sprint planning. Even had meetings where we had to deliver a feature in two weeks, and the agile coach put us all into a room to figure out how we could use agile to deliver this. He also constantly pushed his technical implementations, despite being a non-technical person.

I believe of the 12 devs across two different teams, only one of them remains at the company today.

My first instinct was try and fight it, try to explain why this wouldn’t work. But you quickly realise the agile coach wasn’t there to help development teams, he was there to sell agile, so he could remain employed.
