I have already mentioned the problem in another reply above.

People try mostly the fusion between hydrogen isotopes, or at most between hydrogen and lithium, because these nuclei have a low electric charge, 1 for hydrogen and 3 for lithium, so that the repulsion forces between them are relatively small.

When nuclei with greater electric charge are involved, e.g. boron, the repulsion forces increase. To overcome them, the nuclei must have a higher relative velocity before collision.

There are 2 ways to obtain high-speed nuclei, either by heating some plasma until the nuclei have a random thermal motion with high-enough typical velocities, or instead of heating everything and hoping for random collisions, you accelerate somehow some nuclei towards others, so that their movement is directed, not random.

It is already very difficult to contain plasma hot enough for deuterium fusion. There are very small chances for being able to contain and control the much hotter plasma that would be needed for fusion reactions with heavier nuclei.

So attempting to do hydrogen-boron fusion with the methods tried for deuterium-tritium seems doomed to fail.

The workaround is to abandon the thermal way and to search for a way to cause the fusion of accelerated nuclei, using some combination of electric fields, magnetic fields and lasers.

To produce more energy than consumed, it is required to have a very high probability that the accelerated nuclei will collide with their target (which might be fixed or also accelerated). For this either the ion beams would have to be very dense, or their positions would have to be controlled with nanometer precision or a single primary collision should cause multiple secondary collisions, or some other means would have to be discovered to ensure that the accelerated ions collide with the target instead of missing it.

All of the methods that have been imagined yet have a collision probability lower than needed by a few orders of magnitude.

So several real breakthroughs would be needed to be able to produce energy in this way.

The only hope for this is based on the fact that are no known reasons that would make this target impossible, while for the deuterium based fusion reactions there are a few serious disadvantages that are impossible to overcome, mainly caused by the facts that the energy is produced as neutrons and that deuterium and tritium have low availability.
Thanks Colin! The approach we use does better the more different sources we ingest, so we would love to include results from Mojeek (and some of the great specialized searches appearing). Will reach out to you and thanks for that.
This is really nice, thank you!

I feel like they were just a couple of naive guys who got used by the industry and then chewed up.
Man I'm doing it again spelling similar sounding words, I still get affect/effect and then/than straight though ha.

My use on disqus is a burner context, but that's a good tip if considering using it to host stuff for your own site.

The writing on Medium comment someone made... That's tough, it's like shouting into the void, no response. For ex. I tried Vimeo to get away from YT but no watchers... Come back to YT, people are engaging/looking at it. Which then you gotta ask why are you making stuff publicly, so you want people to see it? If you write your own blog, gaining traction will be slow, probably have to spam existing sites with links to your site. I don't think people post ads for blogs.

Tracking is real not denying that. I search something on Google and I see ads for it later (on my phone, on the aggregated articles feed view in Android) unless I explicitly use Incognito or another browser.

In some places, a thumbs up means "Up yours!" Not very friendly at all.
Wow. I’m in a new relationship and this felt like a contract for marriage. Haha! All kidding aside, I’ve heard business partnership described as marriage, and even read a book about it. This reads like the crib notes for such a book. I liked the bold typography—the explanations were useful, but not required.

After those initial ideas, I started to get bored. I wanted more humor or a story.
Looking from the distance with very little information I can't comprehend the decisions that Hungary has made. Russian are a single point of failure. If there is a collapse or civil war in Russia, Hungary's energy sector is doomed (multiple Russian nuclear reactor, gas, oil, coal). Even now, there is a risk of blockade, carbon tax from Russia.

It does look like a corruption?

How about a link then? It seems like you're trolling or otherwise violating the spirit of HN. I mean calling us all ignorant and uninformed, telling us that we're all wrong, then not explaining how we're wrong. In fact, your second comment conflicts with your prior one (claiming that Bezos can't borrow against stock to avoid taxes, then claiming that's exactly what people do).
Oh no. I'm just explaining why it's more efficient for the IRS to do it this way. I'd personally like to abolish income tax and only tax sales, with up to 100% tax on luxury goods and no tax on food, etc.
Maybe I'm in the minority here based on the comments I can see so far, but I really do value good comments on a blog when they come up.

I do sympathise with writers who don't want to deal with moderating it, working out how to manage them is a problem, but finding the one of dozens of spaces people are talking about the thing written is also challenging.

I mean, my own blog doesn't have comments.

Twitter et al don't really solve this I find because you really can't find the different threads of discussion that are occurring after the fact. It's really not helpful when you're trying to understand what was being said at the time on those kinds of platforms. I don't want to have to be an archaeologist to work out what was being said at the time about a topic.

One recent trend which I do like is authors explicitly calling out spaces to respond to their work, via a link. I see this a lot with HN and reddit threads being called out by the author and it's really nice reading the follow on thoughts of people who've engaged with the writing, perhaps years later from when the initial article was written.

But I do think we need a better solution to this.

Why does it matter? Even if I do post from "trusted sources" no one takes it seriously. Children continue to be prescribed prozac to this day, and now we have the next prozac; MDMA.

Get someone here with a degree in Psychiatry and they are a "trusted source" still giving out this medicine that doors not work for the vast vast vast majority of people.

>>Then you leave and find work with someone that doesn't have the attention span of a goldfish.

Which is basically every where and every one. The bad news is you now start at the bottom of your level at the new company.

>>If you're producing work of value you should be compensated.

How naive are developers really?

>>If the company is doing well then all of the employees should be doing well.

There's a pyramid everywhere, even at F/MAANG's. Some one is always paid more than others, and that some one isn't always making it up on merit.

>>No one should have to put on a song and dance for their managers to get their work recognized and rewarded.

Work isn't an anonymous exam, subjective judgement follows by merely existence of more than one person in a team.

>>If your manager can't remember you unless you're in front of them at all times they're not fit for their job.

Yeah sadly, in a performance review, its us being evaluated not them.
I have yet to implement this but I think a really good idea for blog comments is to link your blog post to a fediverse post. It has been posted here on HN several times already so you can google it but people have done this already.

That way you get the moderation of the fediverse, an account on some AP instance is required, but you can still display the comments on your website with embedded JS.
True, but sooner or later, most of us will have to learn a new language regardless of the starting one.

For example, I started out with Java, and was very quickly forced to become operational with the web stack (i.e. HTML + css + JS and the various frameworks, like Node, React, and Redux), Golang, and Python.

The idea is that the language is just an implementation detail. That's why I commonly see recommendations for [1] - every time you learn a new language, you learn a concept that you can apply in a different language which uses the concept, so the more languages you learn, the easier it becomes (just like learning human languages, interestingly enough).

there could be any of the thousands of police departments in the world requesting the EDR?

Just wanted to point out there are ~18,000 police departments in the US alone. So, the request doesn’t have to come from an unlikely foreign country for this scam to be a problem. Not that this fact absolves the ISPs and others from failing to secure their data via an appropriate verification process.

These are all liberal/progressive policies enacted across the West Coast - Seattle, Portland, San Francisco, Los Angelas.

Progressives believe in restorative justice not prison or punishment. They believe that justice is actually righting the wrong that caused people to behave this way in the first place. "The infinite perfectability of man". That's a core progressive belief. Thus they "catch and release" for non-violent (and sometimes violent) crimes. Reduce property crimes to misdemeanors, and generally tell law abiding citizens - "just put up with quality of life issues".

Suffice to say the experiment has failed entirely.

Lawlessness begets more lawlessness. Giving people a place to shoot drugs (without treatment options) just helps addict get their fix. Not prosecuting property crimes just encourages ever more bold property crimes.

And the funny part is, it's not poverty driving much of this. It's organized crime - easy pickings, low hanging fruit. It's not the single mom trying to feed her newborn milk that is stealing catalytic converters.

I keep saying this, but history repeats itself. Major urban cities saw mass out migrations in the 60-70s for this exact reason. Crime, lawlessness, rioting, general degradation of QOL. The "Death Wish" movie series about a vigilante taking on a lawless city wasn't popular because people enjoyed the genre. I could easily see it happening again, especially with WFH. Then the "law and order" types will get elected and we'll start the whole thing over again.

Ask HN: What bits of fundamental knowledge are productivity multipliers?
I recently realized that certain kinds of knowledge allow one to be significantly more productive when solving a large class of problems.

For example,

* Regular expressions for simple text processing.

* Parser combinators for parsing.

* Parser generators (esp. packrat variety) for parsing.

* The concept of fuzzing and property testing for testing code.

* Calculus for solving all sorts of problems.

* MCMC for solving a huge class of probability problems.

* Search algorithms for solving a variety of problems (e.g. all NP-hard problems, sudoku, HTNs, scheduling, planning).

* Gradient descent for solving a variety of optimization problems.

* Vector Space embedding as a conceptual tool for a variety of complex AI problems.

* Effect composition (Haskell's IO or Scala's ZIO) as an incredibly powerful paradigm for concurrency and parallelism.

What are some examples of 10x multipliers that come to your mind? Fundamental ideas without which you would be drastically less productive.

Why do you think experience of Romanian immigrants in Australia would be relevant to the experience of people with Romanian beggars in the UK? The UK for years was a part of the EU and thus allowed unlimited, no-questions-asked immigration from Romania: the literal opposite of immigration policy in Australia.

Hehe, been there done that. In fact, doing that, right now I'm fixing a window frame that had 'a small spot of rot', by the time it was done half the frame had been removed, incredible how bad wood can be under nicely looking paint. Insect paradise underneath there.
No - they're pseudo-progressive on both fronts. It's not really that. They're passive aggressive. The phrase that always goes through my mind in this city is ineffectual asshole.
Running any public forum mostly means moderation. Trawling through hundreds of spam comments that got through the filters, to find the occasional jewel, ceased to motivate me.

Should we be sad that discussion about a piece doesn't occur centrally, or is it actually better that several discussions occur - each of them with their hosting venue's specific tone ? As someone else mentioned, webmentions might bring the best of both worlds.

would be the first-to-market with catchy
tunes and stadium-filling star power.

This is a profound misunderstanding of how weird and unlikely the Beatles phenomenon was.

Post-WWII acts with catchy tunes and star power were already abundant before the Beatles. They were not special in that regard.

What was unique about the cosmic accident that was the Beatles?

1. Happened to be paired with a (initially reluctant) producer of classical music

2. Achieved worldwide fame and chart dominance (this part is not unique, but its place in the sequence of events is crucial)

3. Somehow this popularity crossed over into the US, the world's largest market, when American response to prior British acts was lukewarm at best

4. After achieving worldwide superstardom, decided to push the boundaries of pop music

5. Conveniently had a producer who could help with and encourage this transformation

6. Decided to give up touring at the height of their fame, to focus exclusively on studio albums, and were able to do this thanks to already having achieved megastardom and financial independence

7. They accomplished all of this in, essentially, a single decade and then called it quits
The community is great too. There is a group of people dedicated to rescuing players who ran out of fuel in deep space. It's impressive to me just how altruistic people can be.

A ton of businesses are dealing with a bad hand right now. They know they cant successfully force everyone back to the office. If news goes out about X entity is going back to the office. Recruiters go to linkedin and reach out to all of those people and offer them work from home and a raise.

Flipside, if you dont go back to the office. What are going doing holding so much $ and costs for nothing? Everyone who realizes this also cant rush out to sell. There's already loads of empty buildings and who is buying? Nobody, you'll get wrecked.

Then add on top, even if you decide to force everyone back into the office and accept the losses. How long until climate change or expensive gasoline forces people to just stay home??
Yes but his point is that if a 10% performance improvement is significant then you shouldn't be using Python!
Americans elect both state and federal representatives. All levels of government are just enacting the will of the people.

If Americans don’t want easy paths to permanent residency/citizenship, it’s up to those of us who do want that to explain to them why they’re wrong.
I agree. Crime is not something that can be eliminated. But you can develop systems where its minimized and others where its maximized. The two extremes of totally policed, and not policable at all, are both examples of systems which will maximize crime. This seems obvious to me which is why I don't understand why people think a completely decentralized, anonymous, unregulated currency, with irreversible transactions is a good thing. It creates as many problems as it solves.
Perhaps they’ll allow you to use it through subscription, like z/OS mainframes locking down cores?
"...not about people like you."

My wife, who spent much of her career in corporate HR, would often note:
"People who want to work, will work wherever you put them. People who don't want to work will find a way not to work wherever you put them."

The people who used WFH as a "2 year vacation" are the same people who will wander the office engaging in random conversations and scrolling Facebook the remainder of the day.

I always wondered why we presume traffic and cubicles are a cure for the lack of motivation.
I’d like to add that I think e-sports will come to overtaking physical sports in my lifetime.

I really enjoy watching sports (pretty much every sport, although I’m a partial to college football) and played sports as a kid but it’s much harder to do as I get older for the obvious physical reasons and the fact that adults don’t have the coordinated free time and schedules of children.

Video games are a much more accessible medium. I see my 8 year old nephew play video games and watch streamers. He can then play the same game for himself. As much as I loved watching Michael Jordan as a kid I could never, and will never, be able to dunk a basketball. There barriers to entry for video games is much lower, almost anyone can do it, such that it’s practically zero. It’s much more relatable and as he gets older I think he’ll choose to watch people compete in the things he grew up with and relates to. Given the shear number of people to game it’s not unimaginable to see how e-sports could surpass professional sports one day.
Alternatively, the world was in a state were these people really did not need really to be working because economy was so slow, and government grants were paying for those salaries anyway, so people were kept on the payroll.

Now that the economy is "back on track", we need them to be working - like they did before the pandemic, not like they did during the pandemic - so the work organisation gets back to a pre-pandemic state.

I always think of Dyson as electric-engine designer company who also makes products out of these engines (i.e. vacuum cleaners or filters). It's a lot of physics, mechanical engineering, electronic, electric engineering, simulations - fun stuff all together. They're not "just a vacuum cleaner company", they really design their electric engines and turbines from scratch (they're really piece of beautiful engineering, took some Dyson things apart), they optimize for noise, vibrations, energy usage etc...

They were even working on an electric car at some moment (I think it's abandoned) - I waiting with excitement to see the electric motors they would design.
I know a few former and current Dyson engineers/designers, I really highly rate the engineering teams there.

I think Dyson (the company) are at their best when they are working in a new product category. They are very good at thinking “outside the box” and coming up with very innovative ideas. I’m somewhat less convinced by their vacuum cleaners now, they were obviously incredible 25 years ago but now competitors can achieve the same (and often better) product for far less cost to the customer.

The Air Blade hand dryer is a good example, it’s so much better than anything that came before it (if you ignore the noise) and for 3-4 years they were the best. Now others are catching up and producing products on par or better. (I would still prefer paper towels and a recycling bin)

My wife was incredibly sceptical of their hair care range when it came out. She tried a friends hairdryer and loved it, now she owns one and one of their other curler type product. Absolutely loves them. Again very different product than what came before, very innovative - and expensive - but very good. I sure that in a couple of years competitors will catch up and potentially surpass on quality and price but for now they have a winning product.

So, as mad as this thing looks, I will give them the benefit of the doubt and will watch how it goes. It would not surprise me if it does incredibly well.

However there have been Dyson flops, their washing machine for example was incredible engineering but they didn’t understand the market. For the first few years you could only get it in bright “Dyson” colours, where, with a lot people here in the UK having their washing machine in their kitchens, it didn’t sell well. Eventually they launched a white version but it was too late. I think they have since learnt from that marketing mistake though.

Just on the “tangent” of their lighting system, that was actually a separate company founded by James Dyson's son Jake. And as I recall, a few years ago Dyson acquired the company and folded it in.
