> Any entity that develops an unlimited, clean and cheap source of energy essentially has access to a money printer.

Well, one thing that should be clear to anyone watching the space is that fusion will be neither unlimited, clean nor cheap. At the very least, not with any approach being looked at today.

First of all, being based on state-of-the-art science and tech, it's clear that it cannot be cheap for another 20-30 years even if it was working today.

Secondly, fusion reactors will produce large quantities of radioactive waste, probably larger than fission reactors, because everything that comes in close proximity to the reactor will be bombarded by 30+ times as many neutrons than in a fission reactor (or 5x-20x as many for DD fusion), and much higher energy neutrons at that, making it brittle and radioactive. Most of the reactor components are expected to need changing every 2-4 years, by which time they will be radioactive waste. Not to mention, fusion plants will work with large amounts of tritium, which is notoriously hard to contain, making tritium leaks all but guaranteed. So, definitely not clean.

Thirdly, fusion reactors require large amounts of tritium, which is virtually non-existent on Earth and must be created in fission power plants. The neutrons from the fusion reaction can theoretically also be used to recycle tritium (when hitting the lithium blanket), but you would have to recapture 100% of the tritium produced this way to recreate fuel, which is not possible. So, to run a fusion reactor you will be limited by tritium availability, and that will mean you also need a small fission reactor, and that in turn requires uranium - so, not really that unlimited.

Not to mention, even Deuterium is not actually that easy to obtain, as you need to either get it from fossil fuels (the way it is mostly obtained today) or from water hydrolysis, which is another waste of your produced energy.

Overall, fusion seems extremely unlikely to be an economically viable source of energy in the coming decades. Every new reactor will require massive investments, it will waste a good portion of its output to keep itself running (powering the superconducting magnets, pumping coolant, void pumping the reactors, water hydrolisis, lithium processing to extract the tritium etc). It will require highly trained engineers to design, build and maintain. It will have a high risk of catastrophic damage to the reactor itself, easily vaporizing much of the investment in an instant if the magnetic containment of the plasma fails, for example, or melting down spectacularly if the cooling system fails. Virtually all components of the reactor, including the high tech magnets, will require constant replacement as they become brittle from the neutron bombardment - and all the old parts will require expensive radioactive storage for at least a few decades to centuries.

You can make a self driving truck/electric vehicle lane where the speed limit is 80km/h. Paint a green line in the middle of the ev-lane and it should make self driving more easy to implement. Reason for slower speed wind resistance is far less at 80km/h. Energy use is quadratic concerning speed. So make a movie streaming ev-lane.

Also one could fit cars with rail gear and run them on rail tracks on the highway which would lessen the tire friction roll resistance losses. Technology for allowing cars to run on rail tracks already exists for railway maintenance cars. Self driving on rail track is also much easier to implement.

https://en.m.wikipedia.org/wiki/Road–rail_vehicle

Safety from car crashes would also be far safer at 80km/h than higher speeds.
When you observe historical data, you see that the graphs of the amount of energy we are able to master are roughly proportional to the graphs of our emissions of garbage (construction, pollution, CO2, consumer goods etc.).

I'm not saying I don't want fusion, I'm saying that without getting much better at deciding collectively what to do with it then those graphs will stay coupled, taking us to a sure doom.

Anyway it's likely we'll get there before fusion so it should not distract us from all other necessary transformations the system needs.
you are right but then you should work to get to a point where you can and will do whatever you want..you can destroy a system 2 ways, within or create your own
> Manufacturing robots kill people all the time[2][3].

Your techrepublic article discredits your statement:

> While any death is a tragedy, it also must be put into perspective. Humans and robots have been working together in the manufacturing industry for decades with few grievous problems. According to a 2014 New York Times report, citing OSHA, at the time robots had been responsible for 33 workplace deaths over the past 30 years. According to the National Association of Manufacturing, there are 12.3 million manufacturing workers in the US, who account for roughly 9% of the country’s workforce.
Unless they changed how inventory commingling works, you might even get a counterfeit item when ordering an item that's sold and fulfilled by Amazon.
That could happen because they consider (or at least considered) items with identical catalog id to be identical, so if for for a given item id, its "Sold by Amazon" inventory is empty while the FBA (sold by 3rd party, Fulfilled by Amazon) is not, they might "lend" one from the merchant until restocking their own inventory.
I was one of the few professional F# devs at a time when F# was ranked #1 in pay (though that wasn't why I used F#). Spoiler alert: The pay difference is not large enough to be worth making a career decision off of. Use the languages you are the most happy with. Niche languages that get paid well don't seem to have a steady spot on the list.

You can't get paid the big bucks if you get forced out of a job for poor performance, and in this economy, expect that to be a real risk.
I'm not sure why we aren't making EVs with small but upgradeable batteries.

Like for example a $20k car with a 10kWh "good enough for now" starter battery that can be bought today. Still good enough for 90% of trips and upgradable to 50kWh with additional after market battery modules should the user decide. As simple as upgrading the RAM on an (old) laptop.
Very light on details. The cause is discussed for 1 paragraph and then it's "Rogers understands... will work on..."
Even though Common Crawl exists, if you wanted to get the data locally to have a bit of a poke around, it's practically impossible.

The next search engine will never be made by a few kids playing around in the shed.

The latest Common Crawl is roughly 120TB, enough to fit on 48 LTO-6 tapes. LTO-6 is the perfect middle ground expense-wise if you did want to play with the entire dataset at home. The tapes cost ~$30 (AUD) each, a cheap loader from eBay can be had for around ~$1000-4000 (like a Dell PowerVault or Fujitsu Eternus).

Your looking at around $8k just to have your data close to your computer. Either that, or you are going to just run everything on AWS/Google Cloud/Azure. Two of these are your competitors.

No one is going to copy 48 tapes for you, either :)

120TB would take around three months to download - if my ISP didn't cut me off first for probably being the heaviest consumer user of bandwidth.

https://www.chatnoir.eu/ has a search engine that is built from the CommonCrawl data running on Elasticsearch, and it runs on 130 nodes [0].

I would love to be able to run my own search engine, but unless there are a number of breakthrough algorithms, I don't see how it can be easily achieved.

I did ask some guys from the Internet Archive if they would be happy to copy some data for me onto some tapes. I wonder if there is a service for this?

That explains a Russian traveler I met at an airport once who asked me for bus fare to some tourist destination. I declined and the bus left without him. He and his girlfriend passed me later and he said "Thanks to you we can't go to (wherever).". I couldn't really understand how someone could be that entitled, but if it's more a blame-others-by-default attitude, it makes more sense.
Yeah I agree it seems likely but Betteridge hasn't failed me yet, only time will tell.
I agree that Google wanted to hold itself to a higher standard, and IMO still does. It's a company that's turned itself CO₂ neutral retroactively, back to its founding, for example. Lots of companies have gone neutral in the present, Google bought offsets for its past emissions too.

The problem with the the motto is that made it easy to hold Google to any arbitrary standard and make that sound reasonable.
It is a case that will happen, when you long-term archive files. Which is exactly what the article discusses. Bit-rot is a real thing that really happens. The argument makes the case that XZ is a poor choice for such a case where you possibly have only one copy and can't just download a new un-corrupted copy.
I used to think that the Netherlands public transportation sucked in comparison with Germany. The trains were normally "dirty" specially toilets. To commute between cities were normally uncomfortable, specially in the rush hours. Now in 2022 (I was in May in Utrecht, went by train from Germany) and i felt like in paradise.
Yes, that would be a good use for it. But:

- Designing things to be durable and recyclable in the first place is probably more economical and sustainable (both can be combined though, no problem)

- Recycling is not a silver bullet. Extracting and re-combining all the microscopic parts of different metals in an iPhone to get back the original metal is incredibly expensive or unfeasible, compared to just extracting that metal from nature

- Unlimited energy makes it easier to go deeper and deeper extract resources from earth's crust, generating more and more garbage. What do you think we'll do, when you observe what we've done so far?
If you do any electronics or signal processing (digital or analog) at all[1], you stop believing that complex numbers are "math wankery" immediately and embrace them as the only thing that's, uh, real.

You mention the Fundamental Theorem of Algebra, I would also add analytic signals. Those are complex by nature, and yet they make so much more sense than real signals ("real" in both senses: non-imaginary and "real world"). In fact, it turns out, real/real world signals are better represented as the sum of two analytic signals.

It's so weird how real numbers, the numbers we consider to be the normal ones, are the special case in a universe that seems to favor complex numbers for the most fundamental things.

My dad just installed 200kW on the roof of his factory. The biggest issue is getting the blip* contract with the grid so you could sell the electricity back, and I mean that at any rate. This is by far the biggest hurdle so having an alternative to store energy that makes economic sense will be the biggest wind in the back for a lot of people wanting to do the same.
This is crazy. How do they pilot the zooming of the fractal? It must be carefully planned and programmed in to generate the video.

The hardest part of building your own search engine is not that it is technically hard (it's actually pretty easy) but that the bar for success is just really high. There are a few existing engines and they offer their services for free. So, not only is the bar really high, you have no viable revenue model and this stuff gets expensive quickly.

Or put differently, if you are going to replicate what existing search engines already do, you are probably not going to be as good initially and you are going to struggle making money. Fixing the money part is the hard part.
What people tend to forget is that "free" normally means, no way to hire as many employees are necessary, no way to pay what they want or need, no way to keep the infrastructure or expand it. As usual in everything involving Government, Free would mean more expensive with a lower quality than now.
People have issues with really visualizing and understanding order of magnitudes, I get it.

> Spend 1/4th that on solar or wind subsidies and you get vastly more carbon free energy

Have you done the math, or are you just making that figure up? One single LWR generates from 1GW onwards. Do you know how much solar you need to generate the same amount of power? And that's disregarding the obvious issues with non-constant energy output.

Plus - solar and wind, if you factor in the energy required to manifacture the components necessary for their operation, have negative EROI. https://energyeducation.se/wind-and-solar-energy-are-neither...

I have literally no idea why people think that solar and wind are a solution to the energy problem. It's like nobody has actually looked into the math and said "wow this makes me feel good so I'll support it". Let me repeat it, solar and wind have _negative_ EROI. If you invest in solar and wind, you're net losing energy.

> 1 nuclear reactor can be quite safe, but 500 of them is 500 times the risk

Modern nuclear is exceptionally safe. Europe is switching to freaking _coal_ in an effort not to freeze this winter. Statistically, they're killing hundreds of times more people than if they switched to nuclear at the right time. They're shutting down most of their nuclear for unknown reasons as well.
But doesn't the major scale confusingly start with C, D, E... and in some countries B is H? (Definitely how I learned it in Germany.)
The octonions aren’t even associative, making them less “natural” and harder to work with.

But quaternions are quite useful for working with rotations in three dimensions. To be very technical, the unit imaginary quaternions form a double (universal) cover of the rotation group SO(3).
> The rest of the sane world will continue to use gzip because the marginal compression savings is not worth the compatibility issues.

It is definitely worth it to use a modern compression format. I regularly take backups of one service I run. Originally I used gzip, and then on someone's recommendation I tried zstd. Here are the results:

gzip compression time: 204s
zstd compression time: 19.1s

gzip decompression time: 28.2s
zstd decompression time: 6.4s

gzip compressed size: 3.0GB
zstd compressed size: 1.7GB

I ain't ever going back to gzip, especially when it wastes so much disk space and CPU cycles.

This idea reminds me of LiGo batteries (https://ebikes.ca/product-info/grin-products/ligo-batteries....).

I think when it comes to the car this idea could be viable but I think the risk is potential change with the weight distribution. You could probably have some weights that are replaced with batteries when you upgrade to keep the weight constant but then you are reducing your range.
That also looks supper sketchy and dangerous. Happy now?

Storage is certainly not harder to build than nuclear power plants. Power-to-Gas is technologically quite straightforward. The research that's currently happening is just to make it cheaper until we have enough renewables for grid-scale storage to make sense. The really hard part of becoming carbon neutral is the sectors other than electricity, e.g. heating and transportation, but nuclear power won't help you there.
Inertial confinement fusion is orders of magnitude less likely to ever be economically viable than magnetic confinement. The targets (and projectiles in this case) will require such high precision to be able to achieve fusion in the moment of impact that it is virtually impossible to imagine this could ever be done economically.

Further, you will need huge quantities of such targets and projectiles, as the power plant will have to destroy them at a rate of one per second or so, in constant operation. So even for a single day, you will require 86,400 targets and as many projectiles - each being a marvel of precision engineering. Also, there is a good chance that you wouldnt even be able to recycle the material from spent targets to make new ones, as they will become radioactive from being in contact with the fusing plasma.

Essentially an ICF plant would actually be running on the world's most expensive fuel, and consuming it at an extraordinary rate.
I find it really funny so many people are up in arms against this perceived “verbal abuse”. The “you” he filled out in the appeal form clearly refers to Twitter as a platform. Maybe it would be clearer if English actually distinguished between the plural form and the singular form of “you”, like in various other languages? Perceiving this as a personal insult is exactly a “pride” issue of the Twitter employee and some of the commentators here, not the author.
So how do you think that we should solve energy storage? Both batteries and dams are dangerous and can lead to disasters. Dams failing have killed way more people than nuclear ever has.
Funny thing is the method of using xrandr or nvidia-settings to scale continues to work just fine.
Under X11 you can use xrandr --scale or with nvidia configured this with its display settings GUI. This option accepts as you specified 1.25 1.5 1.75.

You can also tweak the desired font size to taste
Yeah, if the number of platforms using an obscure corner of the spec were exactly zero, we wouldn't be talking about whether the niche size is worth the hassle.

My point was that this niche doesn't cover the entirety of the embedded / IoT space.

> That rate does not scale negatively with energy prices. It scales positively with population, in the West.

I wouldn't uses "prices" here as a framing. If you plot the graphs of worldwide energy usage and worldwide garbage emissions (let's take greenhouse gases or amount of artificialized soil as examples), you will see that they are correlated. We have grown to this gigantic population solely thanks to our mastery of energy, that's the one factor that enabled all the rest (abundant food, time to go to college instead of farming, developments in medicine to make your life longer, retirements, consumerism etc.).

What I'm saying is that, looking at what we've done so far with energy, it's not entirely sure more energy will be good for our prospects of survival. We need to have a collective philosophical revolution first.

Ha ha, Greenpeace has already per-emptively decided they hate fusion too.
If you want to archive data, you need multiple copies.

XZ or not doesn't matter here. Even if you have a completely uncompressed tar file, if you only have one copy of it and lose access to that copy (whether bitrot, or disaster, or software error) then you've lost the data.
Can't disagree with that :) But most people do agree on lots of things as "bad" - corruption, dereliction of duty, ... insurrection! Could we hold everyone to those?
Ask HN: Is Adobe Dreamweaver still useful?
Remember the old days when Frontpage, Dreamweaver and others provided a WYSIWYG way to create HTMl pages (despite generated code being really mangled, it usually worked)?

I noticed that Adobe Dreamweaver is still available as a seemingly actively developed product. Does anyone uses it for building or maintaining anything significant? Can it help one in creating modern responsive websites, e.g., a small ecommerce shopfront, a blog, etc? Does it integrate well with any of the modern JS frameworks (Vue.js, React, etc) ?
Guess what, that's not blame, but en explanation of the bug.
My mistake! I see what you mean now.
I think the smaller EVs currently on the market can fill a niche in America for city commuters, but only if they're cheap, and I think you'd be stretching their limits for faster highway commuting or longer travel. The sedan sized EV is I think the smartest choice for EVs in the American market, but they're still too expensive.

Plug in series hybrids might be a good stop-gap, as they're cheaper and solve some of the range and size issues current EVs have. You can have a smaller car, still capable of good speed and range, and at half to a third of the cost of an equivalent performance EV.

For anyone not aware of the term, a series hybrid is an EV drivetrain that has a smaller battery and an auxiliary petrol generator onboard to fill the battery if it gets low, or you demand more power from it. At first thought, that sounds ridiculous, but we're talking about compromises to fit specialty requirements here, and in that context they make a lot of sense. (also good EV conversion potential, since all you do is upgrade the battery and ditch the petrol engine once battery prices make sense)
