NIF doesn’t use magnets. Pure inertial confinement. You’re thinking of Tokamaks. Those use superconducting magnets.

Superconducting magnets like ITER uses don’t require energy to continue running as they, of course, are superconducting. They “only” have to dump heat put into them by the reaction radiation. The SPARC reactor by MIT is similar but much smaller by using Cuprate superconductors (high temperature superconductors, but here operated at much lower temperatures to increase the critical field) that allow much higher field strengths. They often have non-superconducting joints which cause a (sort of) small amount of additional heat that needs to be dumped, but it is possible to make such joints superconducting as well. Anyway, all such designs for commercial scale power from Tokamaks use fusion generated electricity to power the magnet cooling, and those electricity requirements are less than the electricity produced.
There are a large number of people who believe nuclear is a victim of a conspiracy instead of just looking at how economics of electricity production has evolved.

Nuclear has been in a steady decline globally since the late 1980s.

At one point - during the oil-crisis 70s nuclear was the cheapest but coal overtook it in the late 80s/90s - being cheaper and more flexible/dispatchable and easier to build. By 2000-2010, natural gas displaced coal and now - in the last few years or so - solar PV and wind represent over 80% of the additional electricity generation capacity added globally.

That's why I don't think it's possible. The priorities and operation of the government change whenever the administration/majority changes. Having decades of consistency like that just isn't going to happen.
How does "I hope you at least pay for these apps" adds anything even remotely relevant to the thread about what apps someone uses as part of their de-googled phone?

Yeah, developers do need to eat, but this (IMO) snarky comment is hardly relevant to the OP.
If you go to an existing power market, there is generally already enough supply for the existing demand. And all of that supply is a sunk cost. The plants are already built. They're not going to get shut down unless the price falls below solely the operating cost.

Building more capacity can cause the price to decline. In some cases by quite a lot. So nobody is going to want to finance it unless they see that either demand is about to increase or supply is about to decrease.

Which is potentially true in the future. Electric cars will need more generation capacity. A carbon tax that causes existing fossil plants to shut would reduce existing supply.

But it's also potentially not true. Maybe the demand for electric cars will be satisfied by an increase in rooftop solar and not an increase in utility-scale generation plants. We don't know when, or if, a carbon tax will happen in a given market.

You guys also had a specific problem. If you're getting waste heat from natural gas plants, and then carbon prices increase to the point that people stop burning natural gas and switch to alternatives, you're not the ones absorbing that demand, you're the ones getting shut down.

So you're in a different market position than would be the case for fusion after the introduction of a carbon tax.
Quantified by global economic productivity, I agree that China and India have seen recent ascendency, but not Russia. China has failed at even developing its own native microchip industry, thus Taiwan has become a political football. We are living in a post-national world where key intermediates come from multiple countries. The Russian Federation is a petro-state that generates less than 3% of global wealth. Sure, they may have temporary disrupted the US political system, but that will run its course. The Republican/Russian cause knows it will ultimately lose because they have embraced the symbol of every other lost cause from the Confederacy to Nazi Germany.

Had we gone down this road, we'd have a thick layer of manure covering everything. Living creatures are a source of CO2 too, and a big one. Look up for a share of greenhouse gases coming form agriculture. Had we used faster horses, that volume of emissions would be effectively doubled or tripled.
What are the odds of runaway fusion occurring? Is there any consideration that a violent reaction could engulf the planet and end life as we know it?
*reduction after state mask mandates in the united states. It's an important distinction because mask mandates in the US were followed at varying levels, from relatively stringent to barely at all. Separately, I don't think anyone ever claimed masks (outside of a properly fitted n95) stop the virus, only that it reduces the spread. Lastly, if an area's hospitals have only a few open ICU beds available, then even 2% would be significant enough to warrant mandates in the future.
The GP meant that a fundamentally slow code can't be made faster that much. Offloading canvas calls without making the rendering itself faster can easily mask the performance issue, which is very relevant (and frequently ignored) in mobiles.
I would go further. Using monads, or any functional programming concept that you'll encounter in the wild, requires zero category theory. I would actively warn anyone against learning category theory for day-to-day use of FP. Learn it if you're interested in it for its own sake sure, it's a great maths subject, but it's basically irrelevant for most programmers imho and a distraction if you're trying to get a simple practical understanding.
I am curious about how such a cache could be setup reliably.

1. Proxy inside the company network that intercepts every request to pypi? Doesn't work well due to https, I guess.

2. Replacing pypi in your project description with your own mirror? Might work, but at least slows down every build outside of your network. Also needs to be replicated for npm, cargo, maven, docker, ...

3. Start a userspace wrapper before starting the build that transparently redirects every request. That would be the best solution, IMO. But how do I intercept https requests of child processes? Technically, it must be possible, but is there such a tool?
5 years ago I knew several co-workers who went to Huawei and got paid a lot of money, so if making a lot of money is your aim, and you don't care about working in the West later, go for it.

If you want to work in the West, know that Huawei's reputation is toxic, and I wouldn't be surprised if future Western employers would be suspicious of you.

Why should we wait for fusion? We can and should do both, and fusion also benefits from storage. Fusion and fission help northern countries in particular as they actually produce MORE energy during the dark, cold months.
I'm a solo founder with a product used by 300k+ people. Keep it simple, don't solve problems before they become problems, and keep all config in Git. I would use Heroku, but my usage requirements makes that cost-prohibitive. Heroku is good for low-traffic projects aka Enterprise B2B. I don't use k8s, I just use shell scripts that import each other for setting up new DigitalOcean servers. I separate my shell scripts into 3 categories:

1. common (Google leap second smearing, increase max open connections, misc security and performance changes)

2. infra (install Nginx, install RabbitMQ, install Postgres, install SSDB)

3. product (run common stuff, then infra stuff, then any stuff specific to a single server)

Sometimes it breaks after upgrading Linux, but it's easy to fix. For CI, I use GitHub Actions. Deployments are mostly built with GH Actions. If deployment fails it just keeps the old server code, there is no need for rollbacks I just re-deploy with working code. If deployment passes but there's still a prod bug, I don't rollback. I just commit a revert and deploy that or commit a fix. LetsEncrypt renewal, log aggregation, db backups is all custom with combination of RabbitMQ and CRON + Shell scripts.

I miss out on autoscaling, so someday I'll invest the time to migrate web servers to hosted k8s. With limited time as a solo-founder I have to prioritize for impact meaning incremental improvements usually never get done.

Not having k8s and autoscaling isn't causing any problems, won't increase revenue, and won't save any meaningful expenses so it's currently only an incremental improvement for me.

Finally, I have a small Slack community for bootstrapped founders. Let me know if you want to chat in there about specifics.

We need to limit speed and the amount of interactions between cars and pedestrians. This will necessarily be at the expense of the drivers who will have to drive slower and get less space since they have historically been prioritized.

It is much easier to implement the necessary measures (against the will of many drivers) if it is clear that drivers run over people, not that people accidentally end up under cars.

Sure, hand held radios start at $30 and at $75-$100 can be pretty nice. State wide repeater networks are pretty common, there's pretty nice ones in Colorado and California that I've used, I'm sure there's many others. Sure an external antenna $30-$200 can really help if you are in a car, house, or even an apartment if you have a patio.

So sure you can blow many $1000s on it, but depending on the hardware and demands you can talk to large repeater network for $60 ish on 2M, and with a bit more skill and testing/certification (A general license) talk to people world wide for a few $100.

Overwhelmed ICUs and hospitals has been Canadian tradition for decades, just google any year (ie. 2018) and "flu overwhelm hospitals" and you'll found countless articles of just seasonal influenza overwhelming the system.

The energy he is stealing is the extra power he is causing to be used by the cooling unit, which is going to his benefit.

If I hook my house up to your house's electricity supply, it's the same thing. Even though you don't have less electricity than you had before, I have caused more to be used that you are paying for and I am taking and benefiting from.

I am in effect causing the electric company to sell you more power, which I am then taking for myself.

Boats also have critical systems such as engines that need maintenance and despite that break often. Esp. on a sailboat, there's nothing more important than the engine and these are usually cooled by salt water.
Listen, i'm pretty sure every person who ever lived in Lille, Strasbourg or Paris would gladly pay a premium to move our 3 plant out of the way (3/21 by the way) if germany stop their peakers, coal plants and industries in the Rhur each time the wind blow westward, especially when the anticyclone is resting over France. Never had asthma before my trip to Paris, and when i learnt that most of the particles that declenched that were due to coal burning and not cars, i became very, very pro-nuclear.

Just so I understand, the one thing about flip flopping on masks cost them to lose faith in all medical experts? Doesn't that seem a little unreasonable? I agree we shouldn't have flip flopped on masks, but I don't think making a whole narrative out of that makes sense.
I doubt the cost figures for wind, solar, and nuclear are off by much, or rather, they could be off by hundreds of percents and still be more accurate than fossil fuels cost estimates which fail to account for pollution entirely.
No, horse breeders argued the supply lines favored horses as horses could be fed by unlimited biofuels instead of limited fossil fuels. Of course, there was a difference in scale, but it’s just false to claim there weren’t major naysayers about automobiles from the horse industry.

It's not that there isn't sunlight, it's that the sunlight is massively skewed towards the summer when it's between +20°C and +30°C with low energy demand, and not during the winter when it's -10°C to -30°C with high energy demand. You could get 24/7 solar power in Lapland for like a month when the sun comes up in June and finally sets in July.

Anecdotally, I use a bike bell and I've never collided with a pedestrian. And when in the role of pedestrian myself, the only time I've ever had trouble with cyclists is when they didn't ring their bell (or have one to ring) or when a cyclist deliberately passed as close as possible to me (I suspect in some selfish attempt to not lose energy with a more courteous but very slightly longer diversion from their straight line of travel.)

I really think a bike bell should be sufficient for your needs. A card in your wheel spokes would also get the job done and be a lot less obnoxious than music.
I'm a javascript developer. My build tool is Meteor and I host on Galaxy. Deployment is one line of code in the terminal. Scaling is handled automatically. :)
No, but I think that it's super common to discount to $0 all the work that using lambda saves you from maintenance and operations.
And if you can do any of that at scale for $250/mo you're lightyears ahead of nearly everyone.

>Covid is essentially equal to the flu in terms of mortality for people under ~55 and children are virtually immune from serious Covid illness.

Previously this would've been "COVID misinformation", but it isn't anymore as the NYT said it this morning. I'd quibble a bit about natural immunity being "superior" but honestly who knows anymore.

>For children without a serious medical condition, the danger of severe Covid is so low as to be difficult to quantify.

that is wrong. We are replacing it with coal in Utah. LA county buys up to 20% of its electricity from Utah, triggering a coal and gas expansion there.
Deno uses v8 too, that would be just comparing libuv to Tokio.
> Solar panels are known to leak lead in the environment.

I suspect you are grasping for excuses. Do modern panels have significant lead in them? Also there is a huge abundance of lead in our city environment already (paints, leaded petrol). Even if there is lead in panels, it is concentrated, and I suspect the total amounts in panels would be at least three orders of magnitude less than that. Back when we used alkyllead additives in petrol, it was about 0.5g lead per litre[1], which would be an astonishing amount of lead put into our direct environment.

And those used panels will still have value to people (eg third world) and will get reused, giving excess value to poor countries.

Sure, rescue workers had some connectivity. But typically in a disaster the rescue workers are overwhelmed and a large part of the community is out of communications. A ham per neighborhood can really help get the word out, even for simple stuff like there will be a water truck at the local highschool tomorrow at 2-4pm.
First up let's be absolutely clear - there aren't many (any?) "amazing new Rust inventions". Rust isn't a proof of concept, it's the mass market product and so it just stole clever ideas wholesale from languages we don't care about, and in some cases haven't even heard of. The various papers saying C++ should do things that Rust did aren't because Rust invented those things but because it has popularized them and now people writing C++ papers want them.

It is true that SFINAE means you can write very general templates in C++ and just not worry about whether they compile with any particular parameters, which is superficially similar to a blanket implementation of a Rust trait. But, because Rust's traits have semantics not just syntax the actual effect is different.

And that makes the blanket implementations very comfortable in Rust, whereas the equivalent pile of enable_if templates in C++ would be trouble.

Remember C++ comes with template language that is explicitly labelled as having unenforced semantic value. It's for documentation, a human reading them can see for example that you expect this parameter type to have full equivalence. However the compiler only cares about syntax, and the syntax just says the type has an equals operator.

This is a great contrast with Rust, whose traits have semantics and so core::cmp::Eq and core::cmp::PartialEq are different traits and the compiler cares which one you asked for even though the syntax is the same.
Doing health checks and restricting foreign nationals arriving from specific high risk areas is not extreme at all, that has been done plenty of times. I don't think it is comparable at all to the unprecedented restrictions that become normal in the last 1-2 years.

>Do you think it would have been OK to implement restrictions at the start of the pandemic, just not now?

Yes. In the beginning nobody knew how dangerous the virus was, so risk management should have been much more strict. It could have been a virus orders of magnitude worse than covid.
We aren’t. MIT’s SPARC Tokamak design could be ready for commercialization by a decade. Less time than completing a high speed rail project in the US.
I used a TI for my physics classes, and wrote code to solve pretty much every problem type.

Really, if it weren't for writing the code, I wouldn't have known the subject matter all that well, and would have likely done poorly. By programming it, I understood it deeply.

Also, I was able to plow through the exams faster than anyone else. I even made the code show the steps so I could show my work as required.
Because they started labelling such arguments as right/left wing propaganda. Labelling any criticism against you as enemy propaganda is a common strategy in authoritarian regimes, and it works really well as long as you have sowed enough hate against the enemy in people.

So even though the plan might not be obvious to those who live in the authoritarian regime, it is often very obvious for outsiders that for example the democratic peoples republic of Korea isn't really a democratic republic.
I think we agree more than we disagree. An overnight timer is ideal right now while most base-load comes from coal and nuclear, and power is cheapest at night.

But as we move past combustion (I'm in Michigan and the amount of coal we burn for power is absolutely shameful) and into more solar, it's less predictable. I can't set a timer that knows when the sky will be cloudy.

This is why I'm so excited to see EVSEs that take data from PV inverters and have a "PV surplus only" mode, where the car is charged only when the sun shines, without ever importing grid power. Modulating 30kW of load is just as good as 30kW of storage, but costs nothing but a few lines of code.

And yeah, networks and middlemen can suck it. Keeping it local is always better.
We figured out ship reactors for some time now. Easier target for global emissions reduction could be getting reactors into some of these huge container ships that are currently burning bunker (on windy.com the emissions are so bad you can see trails where these ships go). I wonder why there's not at least 1 container ship with a reactor yet while Russia's got stuff like icebreakers running them?

I found this to be an interesting read, covers the US's only nuclear powered cargo ship that came a little too early to be a container ship: https://www.flexport.com/blog/nuclear-powered-cargo-ships/
What do you do after the shortage ends? 1300$ isn't a good price for long term, 400$ is. If you try to make a 70% price drop close to relase, you just screw over your next console launch. Sony doesn't even profit from console sales, the actual juice is from PSN and cuts from game sales.

I predict Sony will just cut their supply to Best Buy. They want their consoles to be cheap for a reason.
I'm struggling to understand what exactly happens. The deuterium and tritium mixture is hydrogen -- so it is a gas? So is it in some sort of gas-containing container, that also lets laser light through -- probably some kind of glass container? What kind of glass container can survive having this much energy pumped through it, and such a hot gas inside it?

"Theft of thermal energy" or maybe "thermal state" may be a succinct way to put it. It applies to hot/cool that's being stolen and is agnostic to the energy required to create that temperature.
