Clarification: I failed to secure enough funding to see my 1st project through. I failed to take an idea to market and scale the business on my 2nd. I struggle with the coder/founder paradigm shift. I'm working on it.
Oh course I do, which is why several of my comments in this thread were about the importance of statistics education.

I'm okay with having classes pointing out propaganda so long as it is even handed in pointing out propaganda irrespective of agenda. If a professor only points out the propaganda of those with whom they disagree, that's a bad class.
Yeah the layering in Protocol Lab's work is really nice.

The tendency of funded / for-profit software is to eschew layering, so it's easy to try out but ultimately ill-fitting and inflexible. This is a core problem of capitalism with IT.

IPFS, libp2p, IPLD, Filecoin etc. all resist that temptation, and I think it will help them greatly in the end.
I think at least the sales pitch is that the new magnets is all you need, and apart from that it uses the same well-understood technology that ITER is based around.

I wrote an article with some overlap with Ben's article about this back in March[1], so I've been experimenting with trying to get better audio and video outside of Zoom and other apps.

They tend to optimize for the lowest common denominator. Despite having a nice headworn mic and earbuds, great webcam and good lighting setup, Zoom and other apps tend to optimize for using as little bandwidth as possible so my audio doesn't sound nearly as good as it could.

Ben makes some good points that I didn't mention or consider myself:
- I wasn't aware of Zoom's "use original audio" feature so I'll need to give that a try.
- Dedicated monitor is great; having a presentation monitor allows you to keep your shared screen clean but still have notes and other stuff available.
- Open back headphones to hear your own voice: good idea if you have a dedicated space to yourself, but not if you share the space with anyone else

The biggest problem with this is other people: you won't get any benefits from others if they have a bad setup. So it requires everyone to have a reasonable setup (even just a headset makes a huge difference).

One interesting thing that might not be obvious on the surface is that this is a massively deflationary trend (in the sense that debt is money and educational loans increase the money supply) a time when we are already fighting deflation and have run out of traditional monetary tools to fight deflation (with interest rates already approaching 0)

I actually think less people enrolling in college as it currently exists is a good thing but in the sense above it has the potential to have very damaging side effects (I'm not arguing we should continue the lending just because getting rid of it will cause some pain though)
No it is not. I literally never heard that "white supremacy is endorsed by the state in the US". I heard the highly exaggregated unsubstantiated claims though. (Eg by calling all people wearing MAGA hats white supremacists.)
Federal immigration control almost exclusively focuses their attention on deporting and denying asylum to Latino refugees and asylum seekers.

Last week it was uncovered that mass hysterectomies had taken place at an ICE facility in Georgia without the informed consent of patients - this falls under the UN's definition of genocide.

This policy shift towards targeting exclusively Latinos came under the Trump administration calling Mexican immigrants "rapists" who bring crime and drugs. Melania Trump is a white immigrant who was granted the exclusive EB-1 green card for "extraordinary abilities".

I find it nearly impossible in these circumstances to come to the conclusion that the state is not explicitly catering to white supremacist ideology...and immigration policy is only the tip of the iceberg.
I never quite understood the math behind power densities in a fusion reactor.

In the sun, isn't energy production occurring at something like 100-1000 W/m3? So, if you want to build a multiple MW fusion plant, shouldn't these plants be ridiculously huge compared to, say, a wind turbine rated at a couple of MW?

Is the density of the plasma so much higher in a fusion reactor?

Also, something else I never grokked, how do you get the power out? The plasma heats up, but how do you turn that into useful electrical energy?

Nevertheless of course I hope it does work as advertised... someday.

Edit: thanks everyone for the thoughtful, insightful replies!
And those bitwise operators are defined to convert the number into a 32-bit signed integer as part of the process. Which is why foo | 0 is a way of converting a number to an integer (as long as it's not too large ...).
Not so sure about that. The truth is most users cannot be trusted to make good informed security decisions for themselves.

As technical people we are instinctively infuriated when we aren't given a choice but for most users that's the best option. That's why the iPhone has a much smaller history of apps (and their installed base) that steal user data than Android's. Because too many users see some shiny exciting app description and click OK when the system asks them "are you sure to install this app? it's going to read your contacts, access storage, make phone calls and send SMS, etc".
Some mail delivery systems unsubscribe folks from (legitimate) distribution lists/newsletters once they determine that tracking pixels are not loaded for a while.

Superconductors recently got much better in a way that has cubic effect on reactor size.
There's some discussion about this in this[1] presentation which also mentions the SPARC reactor. My main takeaway is basically yes, high-temp superconductors got "mainstream" very quickly.

I'd recommend watching the whole thing, I found it quite interesting.

The ability of an ordering function that is not a Strict Weak Ordering to cause runtime segfaults when used with sort or an ordered container is .. one of the top vexing things in C++. I think that we naively expect that such a sort predicate could lead to the items in the sorted range in an unspecified order, but not that it could actually segfault! yes, the standard says this is undefined behavior, but boy -- I wish the standard said something else instead. This is particularly problematic because it means that you can't allow user-defined sort predicates. It's easy to imagine a model where no sort predicate a user could write would cause out of bounds memory accesses! but instead, ... yes there are.
Oh so A and B are describing the same scenario, okay.

I think you may have missed the punchline in the story of the defective castings for the Flamanville reactor pressure vessel: the foundry responsible were exactly as good as they used to be, their previous castings going back decades and in use at existing nuclear power plants had similar defects, and they'd just managed to cover it up for all that time. I suspect the same might be true of some of the welding on the existing nuclear fleet too; they've definitely discovered some welding defects.
Aside: Nit: Don't use gradients for discrete categories in a graph. Use a discrete color palette that perceptually distances colors as much as possible using a tool like this: https://medialab.github.io/iwanthue/

Yeah this does not do a good job of explaining itself. Maybe the video does but I haven't watched it.

From what I can tell it seems to be a project with the long-term goal of building a federated VR world atop the Fediverse, with a bunch of building blocks for that split out as separate projects: running untrusted programs from federated sources, storing files on federated sources, transferring money via federated sources, etc.

From a higher level I feel like, you know how there's a whole bunch of projects/companies/VC sinks whose description is "here is a familiar function but ON THE BLOCKCHAIN"? This is a bunch of those but ON THE FEDIVERSE instead.

And with cute painterly mascots instead of weird little single-color abstract logos.
In business school on Mars they'll be thanking the terrestrial telecom industry for giving Elon Musk the break he really needed.

After 20 years of "talking to the hand" to telecoms about improving service, Elon Musk is going to look like a hero to governments of all sizes all over Earth who can take credit for Starlink, even if all they did was get out of the way. What SpaceX will get out of this in terms of profits, as well as political capital will be immense.
Seems many people haven't been exposed to a systematic overview of the topic otherwise, and it works great at providing that. At least that'd be my guess where your experience differs.
My experience has been that I never learned much negative about my city/state/country in grade/high school. I had to learn all those things elsewhere.

ITER isn't meant to be a practical design, it's for research. So it's not obsolete just because it's using inefficient magnets.

I like to imagine this in my head:

What if we were stuck on a spaceship with 100 other humans? There’s a lot to maintain on a spaceship to keep it operating so we all don’t die.

What if there was a contingent of 10 people on this ship who refused to help with the operations of the ship? They decide to hole up in the cargo bay, doing nothing but feeding their own desires from the replicators.

90 other people bust their balls to keep the ship running - long hours, deferring pleasure until the work is done, earning everything they work for.

Now multiply the size of that ship by 70,000,000 and you have Earth.

As a Colombian leftist it is quite difficult to find educated and challenging views from the "right", I work with a lot of veterans and most of them are blinded by their ideology, no matter what the government does or says they will always back it.

I have come to realize that right wingers are brainwashed or people with mental problems or childhood traumas, like our ex president (Alvaro Uribe Velez), who was addicted to kill people with chainsaws, or military men that as part of their training are tortured [1], and are subject to psychological training that change the way they behave.

>Programming the WorldWideWeb client was remarkably easy on the NeXT. There was already a software module, the Text Object, which was an editable multifont editor. I just had to subclass it to make a hypertext object, and add the internet code. Designing the app’s menus was trivial — just drag and drop with InterfaceBuilder. The code framework of the app was generated automatically. That is a platform: something which allows you to build things which without it would have been possible, but a lot of work.

Strange to think what the web would've been if Berners-Lee didn't have such a strong platform and tooling to build his ideas with.
Good point. Would switching the language help? E.g. if you learned Spanish (secretly!) and used it only for the purpose of writing, will a de-anonimizer still work (typos, punctuation should be easy to automatically take care of)?
When publishers consider book proposals, they're always thinking about how easy and how expensive it will be to market the book to people.

Paid advertising is effective, but extremely expensive.

Getting press coverage is great, and less expensive than advertising, but you've got to pay a publicist who knows what they're doing, and even then, there are no guarantees.

But if an author has a strong platform, such as an email newsletter with tens of thousands of subscribers, or a popular website or YouTube channel with tons of views, then it's an incredibly effective and inexpensive way to market the book. The author has already established an audience who has shown interest in their previous content, so chances are good that they will show interest in the book as well.
Imagine some water freezing. This will often start from a nucleation point and spread out rapidly. If this hits another volume of water nearby that's doing the same thing, you might get a crack in the ice where they hit each other. This is kind of what cosmic strings are. As the universe is cooling and quantum fields undergo phase changes, various regions will spread out and the point where they collide can form a cosmic string. (This is all very theoretical and my explanation is rather vague and handwavy).

The question posed is not whether the political viewpoint of academicians lean in a particular direction. The question is regards to whether government-funded schools enact the biases of the government.

Dream-shaping tech from MIT channels suggestions into your dreams
I think the reason is slightly different. I worked for a web company that made most of its money on ads. Companies have an army of marketing "specialists" whose job it is to find "incremental revenue". Their performance is rated on how much revenue they can add to the company. The possibility that it may cost users in the long run is not part of their calculus. I learned to hate meetings where someone mentioned "incremental revenue".

Big companies need to have an ombudsman department who have the explicit job of reviewing all these schemes and nixing any that will likely lose customers.

SAP Help Global Outage
The arxiv paper describing the design concept is here:

https://arxiv.org/abs/1409.3540

Some additional features (besides the magnets) that jump out at me:

The reactor vessel has joints to allow it to open up for maintenance access (previous tokamak designs have a reactor vessel that cannot be opened up once constructed, so maintenance inside has to be done through small access ports using remote manipulators).

The external current drive for heating the plasma to ignition looks like it is more efficient than previous designs.

The blanket around the reactor vessel is liquid instead of solid, using a fluorine-lithium-beryllium compound.
It was a really excellent post. Thank you!
Is it wrong to suggest that this (if accurate) is a positive trend? I would like to live in a society where people spend more time considering what they say publicly, keeping to themselves, and refraining from imposing their thoughts and opinions. Live and let live.

If you want to have a private conversaion, social media doesn't seem to be a good vehicle for it. Much like airing your dirty laundry in the town square has been considered bad etiquette, airing personal greivances on the internet seems to be in poor taste.

It must be noted that manners never arise sponaniously in culture, but becuase people fear the consequences of breaching etiquette. I for one welcome the return of politeness to society.
I use "choice" in its commonly accepted definition for simplicity. We can get into semantics if you'd like. Determinism doesn't mean it's impossible to change the "choices" people make. It means it's impossible to change your own utility functions which cause the "choices". Society can still effect peoples "choices" by punishing them because that will change the outcome of the pre-determined utility function. Incentives are everything.
As an Indian residing in India this certainly feels so.

Things have become bad enough that people self-censor. People have been arrested for sharing jokes about politicians to their personal friends over email or social media. Some have been heckled and beaten up. Such people have no recourse. Even if the local govt pretends to act, the perpetrators immediately gets a bail, because the courts are very much in bed with the politics, more so at the lower courts.

Made up and nonbailable charges have been slapped on university professors who have criticized the government. They are not tried on the usual court but handled by a special anti-terrorism body called the NIA that has special powers and provisions to secrecy that ordinary courts do not have.

Political opponents are harassed by income tax raids even when nothing much come put of the raids. Its just an intimidation tactic where people with government authorization tear your apartment apart and grab documents that they can hold on to as long as they want for the harassments value.
Ehhh, I don't agree. Like at all.

If they had a 2D text input they wouldn't be able to do momentum in swiping as well as horizontal (side effect of the horrible remote), but more importantly, the primary text input on Apple TV is voice, in the moment just hold the Siri button. It takes in letters over voice too. Worlds faster than any other input on tv. No wonder they prioritized on it.
We still have a robust ecosystem of quality journalism in the US. There is bias, there are mistakes made, and there is false information masquerading as news that can mislead media consumers if they are not careful. But we are still very far from the situation in China and Russia. To be clear there is a problem, and it's growing, but let's not exaggerate.
That was one advantage of Google Circles (or Google Groups or whatever they were calling it before they killed it): you could define different circles and send messages only to specific circles if you wanted. It seemed like good way to do it, but of course, as with all things Google it was killed.

I heard this from other friends of color that describe strikingly different experience while visiting or living in Europe. I grew up in Slovakia which as non-diverse as it gets. The country is quite racist, but in a very different way than I seen in US. It's more like "everyone different is bad" than "people x are bad".

What I observed in US that the country really takes an advantage of "poor" people (This is not meant to be derogatory. It supposed to mean people without immediate means. I'm not trying to make a statement about how they got to where they are). And because minorities generally are at the bottom of wealth, this tend to fuel the racism even more.

I always thought that a strong safety net system would ease the situation and allow for the most vulnerable groups to gain some footing which would be better for everyone. But I found over the years that the system racism is so powerful and so deeply integrated in the society that there is no way they will let it happen.

I never figured out any solution to this problem which frustrates me immensely.
>I have many very interesting conversations with people that I do not agree with politically, but I respect their intelligence and point of view, and vice versa.

Likewise. But I wasn't saying that's not possible, I was saying that I'm not convinced many people change their opinions over the course of such conversations. Being civil is important, but the question was whether civil debate among people who know each other in person results in more reasonable opinions, or compromises.

It's obviously better than online conversations. But to what extent? I don't think GP made a sufficiently convincing case.
The humanities in theory would teach humanity. That is, the patterns of literature, philosophy, art, and communication that lead to the best human outcomes and amplify human talent and virtue. It should be training in how to engage with the wider world productively and positively.
The world is a sad place, the fact that we have to pay a premium so we don't get features.

We need companies to rise up against this bullshit. It won't matter until the customer base is educated in privacy.

We need a massive campaign to spread privacy awareness. Only then, there could be a market. Apple can afford to do this because they're big and they already have a customer base. A mid-sized company trying to sell privacy oriented products in a mass market is going to be left in the dust.

The society continues to regress. No one cares.

The "Alcubierre drive" isn't an engineering design for a method of propulsion. It's just a nickname for a certain valid solution of the Einstein field equations.
