From Lidsky:

>Fusion will almost certainly have a lower power density than fission and therefore will require a larger plant to produce the same output. Suppose a fusion plant had to be ten times as big and therefore likely ten times as costly — as a present-day fission plant to produce the same amount of power.

Fission is currently not cost-competitive due to the expense of ensuring that fission reactors do not pose an unacceptable risk of radioactive contamination in their vicinity. However, fusion is not subject to this constraint, or anyway suffers from it much less. There are no long-lived radioactive byproducts, and judicious selection of the construction materials (already implemented) can ensure that neutron activation of the walls is not a problem either. Furthermore, the inherently unfavorable nature of fusion reactions mean that criticality accidents ('meltdowns'; a la Chernobyl) are not possible.

From Pfirsch and Schmitter:

>It is shown that the claims made therein for the economic prospects of pure fusion with tokamaks, when discussed on the basis of the present-day technology, do not stand up to critical examination.

The analysis in the fulltext relies on a variety of plasma parameters estimated based on technology available in 1987. I cannot immediately determine if it generalizes to designs using HTS, but the comments on pp 1473-4 about the achievable B field strengths and corresponding betas suggests that they do not. Cf. this paragraph:

>Another possibility is to use higher magnetic fields: 6 T instead of 5 T would increase fw to values between 1.3 and 2.0 MW/m2, which are still very low. The latter comes close to the value of 3 MW/m2 obtained in Sec. IV.A.l from thermal wall load constraints. Higher fields would, of course, again increase the cost.

Overall I don't think that these links provide nearly as strong an argument as you suggest they do.
Want to sell to VPS and C-suite level? Find the ones who recently changed jobs
This year so far, 50% of the potential customers our team has started a conversation with are in a c-suite position.

Every entrepreneur has struggled to start a conversation with one of these individuals in cold at least once, the reason is that these people are extremely busy and receive multiple requests a day from people like you.

So, what's the secret?

Timing is the key.

When one of these high-decision-making managers changes jobs, they are likely looking to shake things up internally. New processes and new ways of doing things will be on their minds, and they might even have the budget to bring in new tools/services.

More, if these managers joined a growing team, you’ll likely find an even higher level of urgency to find solutions that accommodate the growth of the team!

This is the type of insight that helps you bring a new life to your business. You can reach a buyer with authority and sell much faster.

I've been perfecting my cold outreach strategy with these individuals over the past years.

I have gathered these insights and provided detailed steps on this guide. Feel free to take a look at it: (https://blog.amplemarket.com/uncover-timing-and-budget-when-generating-new-leads/)

Hope you found this insightful!
Unfortunately the paradox of tolerance is trivially abused. If someone concludes that Islam is intolerant, that person feels that the PoT gives them moral license to behave in tolerantly toward Muslims. I think we also see this in American culture war where the definition of “intolerance” is contorted such that it matches one’s ideological opponents. Perhaps we need a firmer test for what constitutes tolerance or intolerance, although even then the semantic contortionists would probably just redefine the terms that constitute the test.
What, out of curiosity, would the catholic church have to do before talking about what the clergy has done stops being "hate speech" to you?

Edit: Im guessing you actually meant hate speech, so I'm changing "gate speech" to that. I thought you were referring to some kind of gatekeeping
I don’t really see what’s different, honestly. They’re moving it from one system they control to another, big deal. Plus who says I even saw the original e-mail?
I'm sure I've encountered several Pfeilstorchs working on software.

Yeah. There are a ton of things where "surely someone somewhere would want this and might even pay a nominal sum for it" is probably true. But spending a couple days setting up a yard sale, arranging things on Craigslist (much less individually packaging up and selling items online), etc. just isn't worth it.
Engineer doesn't "imply calculus and physics". Calculus and physics is not in the dictionary definition of engineer. In fact, the verb form of engineer is exactly what software, network and devops engineers do. When you say it doesn't mean anything, you must mean you, yourself, doesn't know what it means. ;)
When inuits and desert tribes adapted, my understanding is they were either able to adapt on their own timeline (moving gradually into harsher climates as they figured out how to stay in their summer camps longer into the fall) or they suffered immense population loss during the move, and it was a small number of survivors that rebuilt the population. There aren't a lot of records from when humans first moved to now-populated parts of the world, so I could be wrong.

That said, climate change is going to force us all into rapid adaption as plant and animal life die off, glacial streams and rivers dry up for good, sea level rises, etc. It will be easier to survive if you can afford the more expensive food and water, can afford to install the most-effective fire break around your home, can afford the expensive land in still-habitable places.
They should make it a lottery system and show a random 10 people. The threat/possibility may be enough discouragement.
I first saw it in Typed Racket under the name "Occurrence typing" [1]. It's not a coincidence that Typed Racket is also a type system applied retroactively to a dynamically typed language. The first mention of "occurrence typing" in scheme I can find is a 2008 paper [2]

I grew up with an Atari ST and I've enjoyed revisiting it. Growing up I stuck to really simple stuff, so it's been fun to to learn more about how it all works. There's a library called Atari Game Tools (AGT) that can do some really impressive things even on a stock STFM. With cross-compilation tools it's possible to build software on a PC in a few seconds before testing in an emulator.

The VIC-20 is another fun machine to work with. There's not much memory and the way it handles graphics is quite interesting.

The same phenomenon happens without computers when bureaucratic rules are applied senselessly.
Honestly when I first got the dish, and had it in an open field, that was the case—but now the momentary dropouts between satellites are less than 1-2 seconds.

They had 1000 or so satellites when I first started testing, and there are now something like 1600 or so. Most of the time, I don't even notice when it switches satellites.

If you were doing some more real-time work or extremely latency-sensitive operations, then yes, you need to stick to a different type of connection. But it's really seamless now, compared to even a few months ago.

Most of the software I used either showed no sign of the dropout, or at worst would freeze a frame or show a loading indicator for a brief moment before getting back to normal.

Online multiplayer gaming and/or streaming are the main areas where I'd have to not recommend Starlink for now.
100W is a couple of light bulbs. It's not nothing, but it's not all that much. It'd be challenging off-grid, but not a concern anywhere with electrical infrastructure.
How to Build an ML Platform from Scratch
I disagree. It sounds more to me like "I haven't thought about this much, but I caught a wind of someone who might be casting judgement upon me or people like me (those of us who haven't thought about it much). I do not like this, and rather than thinking about it, I'm going to mock the idea." ... which is all too common.

IMO, legit questions:

- Is Sylvia Plath defined by her death? Or just by the tragedy she wrote about, and lived?

- Is she thought of differently due to her sex, or to the very dramatic way (and circumstances under which) she took her life?

I lean toward this not being sexist as much as circumstantial. There's something about "killed self with gas in sealed room next to sleeping children" that strikes people as more tragic than "killed self with shotgun alone in mansion" -- i.e. the first sounds more like protracted desperation, and the second might be an act of brief despair. Of course the truth (such as we know it) is more complicated than that, but complication doesn't survive contact with general awareness.
The issue is the ad is basically worthless without the tracking. No one wants to blindly advertise. They want to target, and then track the effectiveness.
I thought it was significantly more expensive to bury high-voltage transmission lines because the current corrodes the insulation needed to bury the lines, so you have to dig up and replace every 20-30 years. I was actually quite surprised to learn that above-ground transmission lines in the US are uninsulated for this reason.
As mentioned in the NPR story, it's about 10% of their distribution and transmission lines.
I don't understand why they mention the terrorist so much in this in memorial, also photos of him in combat gear. The majority of comments here are about him and his deeds; this is exactly the kind of thing these people want, to be remembered. Discussion about motives, political background are warranted but these people really should not be remembered by name or face.
Ideally the decision would occur at compile time rather than runtime, to eliminate the dispatch overhead, so I think it would be likely to require macros, constexprs, or whatever compile-time execution mechanism is available in your language of choice
I have a printed copy of Knuth's "Digital Typography" on my desk (hardcover from 1999). The table of contents does not look too great, but the rest of the book is a piece of art in itself.

Well your claim is a lot more expansive, really, because you’re saying that I have no right to sign up for the service myself because you don’t like the business model. There are some things that are so harmful that that makes sense but I don’t agree that Gmail and Facebook being in that category.
Just state your point explicitly?

As a thought experiment, do you think there would be so many casualities if this island was located in Texas, USA where socialists/labor party is also not very popular?
> "It's sort of mentioned, but not emphasized in this review that connection dropouts happen every few minutes for a few seconds."

He mentions that this is due to the Starlink dish's view of the sky being partially obscured by trees.

This will presumably improve as the number of Starlink satellites grows, as it will be more likely that there will be an unobstructed satellite in view at any moment, and less frequent switching between satellites.
Is that a function of the wavelength it's using? A quick search suggests that starlink uses 10-12ghz, are trees opaque at those frequencies?

OK, that’s how you feel, and your choice. What do you think about people who wouldn’t mind being spied on in exchange for free or cheaper services?

I’m personally with you, by the way, but I think it’s worth pointing out that it’s not the only valid position.
> Unless you're in the "billionaires must not exist" camp, which we could argue about, they'll still be very rich, given the scale and success of their businesses. A net worth of $50 billion vs $150 billion doesn't change all that much, for the U.S. treasury or Bezos.

They should be okay with $10 million. Average worker will never be able to accumulate even $1 million during their lifetime.

> There are many thousands of Amazon workers making six figure salaries.

Amazon has 1,298,000 workers. The 1% you are referring to, does not make Amazon a good company. Furthermore, given how much money Bezos was able to skim, the six figures are still laughable.

> The fact that low skilled jobs pay crap is in no way unique to Amazon

Yes, because we don't have proper regulation - like making sure highest pay is no more than 10x of lowest pay or linking minimum wage to company global revenue (with a minimum threshold).

> and I doubt Bezos or Musk would object for reasons of greed.

They would object, because people on UBI wouldn't have to work in their sweatshops.

Only if it is profitable. More likely they would move banking off-world to shield themselves from paying taxes.
Well, I don’t find it that much easier to believe just because you assert the opposite.
It might be a rule of thumb, but it's not an axiom (otherwise, there could be no counterexamples). Some software defects are only discovered years later, but can be fixed in minutes.
The art of optimizing a typeface for print is pretty elaborate, and if you're genuinely interested in learning how to do this, https://typedrawers.com is a good place to start. It's where all the font engineers, as well as foundry owners, hang out.
That's probably because you're just used to it.

To any professional type designer, it's a terribly balanced font aesthetically, basically every letterform. It looks like a font designed by an engineer, not a designer who knows how to create and balance shapes and lines that are pleasing and easy to the eye. Which, of course, is exactly what it is.
No, the existence of ethnicities is old but the concept of tying them to national borders is very young (modern era, and mostly 19th century and beyond) and the specific interpretation of ethonationalism here (ethno exclusionism within a set of borders) is even younger.

I have to work right now so can't work through all the examples listed by another poster below, but will try to come to this thread later. But if you look at e.g. historical Europe or Rome you will rarely find borders defined by ethnicity, and you will rarely even find people defining themselves by a singular ethnicity. Look at the e.g. Franks, the Germanic political entity that ended up defining modern France (and Holland and Germany and Belgium, etc.) A Germanic-speaking tribe that took over a Celtic (Gaulic) and Latin speaking territory, went to war with other "Germans", switched to speaking Latin in some places, but not all, and on the territory where they once ruled you now have a shattered mirror of dozens of ethnicities ("German", "Dutch", "Walloon", "French", "Alsatian", etc) in a nested fractal pattern depending on what lense you use, none of which correspond to any exact political border and which are fluid and changing from decade to decade.

My take: Ethnicity exists, is fluid, etc. Ethnonationalism is a tool, an ideological tool, mobilizing ethnicity for its own ends, using a specifically modern era mechanism ("nations", which are only ~200-300 years old) for the purposes of whoever is wielding it. E.g. the ambitions of an e.g. Milosevic type personality.

My ancestors are from both Alsace and Germany, so I take an interest in this topic.
This shows that we should take good care of our surroundings. But I still do believe that the climate will still take a hit in the following years. We should think of a long term remedy for this one.
I went backwards and forwards on buying a Sony PCG-C1VN subnotebook at one point, which was powered by a Transmeta chip. In the end I went for an Inspiron instead which was probably the sensible decision, but I regret it sometimes.
This should be labeled as misinformation just out of spite. And it is, it lacks information and no doctor would accept this as a consultation.

So flag happy Google should label it as misinformation.
IDK about OP, but when I think IoT, I think small single purpose devices: a ring door bell, a "smart" thermostat or fire alarm, a security camera. There at most a couple of processes running, what is there to orchestrate on an IoT doorbell?

On the backend where you have services being fed, processing, and presenting all that data sure Kubernetes that part up, but that doesn't seem to need a special distro of Kubernetes.
Knuth's original are not really raster fonts, they are vectors but in a format which is not supported in other systems so they have to be mapped to raster fonts before being include e.g. in PDF files. The important difference is that you can customize for which resolution they should be rasterized, so you can get good looking fonts by setting sufficiently high values for your screen and zoom requirements. (Of course this doesn't help if you only get a finished PDF from someone else and for the Type 1 variants it's no longer important anyway.)
Free software gives control to the user, that being the person running the software.

If you're not running the software, but instead using an API to the server where I'm running it, then of course you're not in control; you're trusting my word I'm actually running the software!

What's worse is I feel like I can't trust anything I hear because I'm just trying to get sold something. Look at the FDA and it's recent extremely controversial approvals. If you can trust regulating boards anymore meant to keep you safe then there's nothing you can trust.
I will die on this hill that Slashdot moderation was the best I've used. It made moderation or voting a privilege and not a right so I think people took it seriouisly.
The minute this matters for anything algorithmic, it's going to be abused like a rented mule by bots and insane people to brigade any kind of opinion that they disagree with.
One of the few concrete changes I think would improve big tech, privacy etc would be to require providers over a certain size to offer a paid option and then NOT advertise, track, share data etc.

Maybe the price would be stupidly high. Maybe 99.9% of people wouldn't pay. But at least the option would exist.

We could even require providers to link the price to the advertising etc revenue missed.
It's a little less than a modern efficient fridge (2-3 kWh/day). I used to have 100W light bulbs in the house, so it's not a crazy amount of power, but it's most significant to anyone planning on using Starlink 'off-grid', since it's a lot more than just a little 4G or 5G hotspot, or a standard DSL or Cable modem and router.

The best time I had so far was with dockertest[0] in go it allows you to spin up containers as part of your test suite which then allows you to test against them. So we have one go pkg that has all our containers that we need regularly.

The biggest benefit there is no need to have a docker compose or have other resources running locally you just can run the test cases if you have docker installed.

Hydrogen burned in combustion turbines would likely be cheaper. For this use case minimizing capital cost is all important; the cost of the hydrogen itself much less so.
That’s an even better example of my point. The size and frequency of wildfires overall is increasing, but the probability of a fire striking one particular area in a given 10 year period (ie, burn scar still obvious) is still very low.
Magic Raises $27M Series A
I don’t disagree with the maybe, because of course some bugs really aren’t that bad. But especially in the case of those architectural bugs, it is incredibly difficult to be confident that the impact of the bug is as limited as you think it is. Additionally, if you couldn’t take the time to fix it in dev, it is also pretty likely that it will live in production for a long time, possibly forever. And these bugs have a habit of prompting code smelly workarounds, interacting with other bugs, and generally making your system harder to reason about.

It could be the right decision to not fix an architectural bug. But it is a gamble, with a very long tail of cost for getting it wrong.
Like? Because I've never seen XeLaTeX do something that made me go "wow time to go back to the legacy tex-that-doesn't-understand-unicode->DVI->PDF route".
Reasons for switching contracts can be numerous, and, from my experience, the level of support and quality of the actual application is rarely one of such reasons.
>but not emphasized in this review that connection dropouts happen every few minutes for a few seconds

I don't see this at all. I have constant uptime monitoring, and connection drops are now a minute or two per week. We use it for VoIP, there is no cellular coverage at all where I have it deployed.

Edit: Also, I mentioned this in my fuller main comment but this is around the 45th parallel in New England, and around 1500' (500m) above sea level. This location is also within approximately 50-70 miles ground level of two separate Starlink ground station installations. The nature of Starlink is that there is much more of a geographic component than most people are used to in a WAN link, so it's probably important when talking experience to specify rough area of the world one is in. Once the network is completely built up that may not matter much anymore, but at this point there are definite coverage density differences, and with the current bent-pipe usage ground stations matter too more. Anyone interested in getting an idea of current planetary station and sat deployments might find this site interesting:

When ideologies are suppressed, they get pushed to the edges, where there is always some scum of society, who are disaffected and will latch on to it.

The best way is to identify the roots behind what attracts the followers of these ideologies, address any root issues, and attack the premises behind the ideologies itself.

Not talking to these incidents, but all over the world, people tend to violence when they feel that the system does not hear them.

>Sure, but that happened well before WWII, while the obesity epidemic started sometime around 1970-1980

This is not correct. Mass-scale industrialization of US farms didn't start happening until the 1930s. Remember that it was the internal-combustion engine (not the steam engine) that permitted the use of tractors and other machinery to supplant human and animal labor.

Now consider that it takes time for humans to become obese. The children raised during the beginning of the massive agricultural surplus were precisely the ones who were fueling the start of the epidemic in the 1970s.
