This just isn't true.

With geographical redundancy, pump storage and some batteries (or alternatives) you can get the reliability of the current grid. In 2015 (before the introduction of large scale battery storage) they studied this in Texas and showed how little was required for grid stability. In this case they used natural gas (which remain an option), but nowadays there are completely renewable solutions. Note that this covers more than 10% of the entire electricity generation capacity of Texas.

> In a study commissioned by the Electric Reliability Council of Texas, General Electric calculated how much new reserve capacity will be required as Texas increases the amount of wind energy installed. The report found that an additional 15,000 megawatts of installed wind energy only requires an additional 18 megawatts of new flexible reserve capacity to maintain the stability of the grid. In other words, the spare capacity of one fast-ramping natural gas power plant can compensate for the variability introduced by 5,000 new average-sized wind turbines.

It's not one or the other. Renewables on their own can't work. They need to be paired with another energy source. This is where Nuclear (or coal or else) comes useful.

This is why people are uncomfortable with mandatory vaccination orders. I’m pro vaccine and in general well tested vaccines are very important for eradicating some pretty awful diseases. I have all of mine and I’m thankful my parents were sane and paid attention to science.

Safe modern medicine involves care and testing, that’s the whole point of organizations like the FDA. If we just carelessly push stuff like this through we can end up with some pretty nasty stuff.
Stupid question. What are the use cases for such massively fast write speeds?

If you are storing data to disk at that speed, you fill even the biggest optane drives in a couple of minutes. So it would be an application where you need to overwrite a huge amount of data over and over again.
Nerve agents could be attached to much smaller delivery platforms. If you could build a drone the size of a mosquito you could use it to deliver a tiny, fatal dose of nerve agent to your target. No chemical explosive could match that level of miniaturization.

It may be sci fi at this point but it seems entirely possible to me. After all, mosquitoes exist and their behaviour is quite sophisticated. They’re able to locate mammals by detecting our breath, bite us to steal some blood, then fly away their eggs.

I'm not sure what the point of your question is. PV, wind and geothermal don't produce nuclear waste and they only turn into waste after EOL but this applies to any construction.
To be fair (I know you were only making a theoretical example) if you have a bathroom exactly 3.60 meters across, you won't anyway fit in it 12 x 30 cm tiles, nor 6 x 60 cm ones without cutting one because of joints between tiles and thickness of the tiles.

As a matter of fact in a 12 feet scenario 12 x 30.48 cm = 365.76 cm it is actually likely that you will be able to fit 12 x 30 cm tiles without cuts (but not 6 x 60 cm ones, unless you put them with very wide joints).

Carpentry/Construction is done in millimetres (with the occasional length shortened to metres). I've never heard anyone use cm.

Eg: to pay for some timber at bunnings you might say: "ninety by fourty-five. one length at two-four". (90x45mm timber, 2.4m long). On site - if you needed to cut it - you would measure and cut at "twenty-three-fourty-two" (eg: 2.342m or 2342mm)

What prevents nuclear waste from being brought to were it came from? Can't you just grind up the nuclear waste and mix it up with the excess rock to obtain a material mixture that has background radiation than the mine it came from?
Well, it's being done for all the wrong reasons, but I'd gladly take a relaxing of safety measures to be done with COVID, depending on the vaccine and the risks.

The relatively known risks of some types of a vaccine seem a lot better than the unknown ones of COVID.

I would want to wait for full phase III before we had a mandatory vaccine, relied on this fully, or otherwise did too much with it. But we can't ramp up production that quickly regardless. A pilot with a few million volunteers seems as good as any phase III. And with the right few million, it could potentially really curb spread.
Nuclear power is not safe and never will be. This ship sailed with Hiroshima and Nagasaki.

They are repeating that nuclear plants are safe now. "Safe" of course if some conditions meet. If your car is a parking your probability of dying in a car crash is really low, this is obvious. What really counts is their behaviour in hard times. "If all go well, and we have luck, and everybody behaves, nuclear is safe" is not enough.

> One of the deep insights of special relativity is that these scalar and vector quantities are actually unified into a single, new entity called a "four-vector".

> But the really weird thing about this particular four-vector is that it always has a magnitude of exactly the speed of light. No matter how fast you go, the magnitude of your four-velocity does not actually get larger. All you do by going faster is just mix some of the time component of your four-velocity into the spatial components.

This seems strongly to be confusing the map and the territory. The maths is a model, the description of vectors has not link to reality but happens to model reality in some useful way (reality and the model correspond to some useful approximation), but it isn't reality.

so

Not a big problem given so many alternatives around like

E.g. some very active projects are:

* Kaldi (https://github.com/kaldi-asr/kaldi/) obviously, probably the most famous one, and most mature one. For standard hybrid NN-HMM models and also all their more recent lattice-free MMI (LF-MMI) models / training procedure. This is also heavily used in industry (not just research).

* ESPnet (https://github.com/espnet/espnet), for all kind of end-to-end models, like CTC, attention-based encoder-decoder (including Transformer), and transducer models.

* Espresso (https://github.com/freewym/espresso).

* Google Lingvo (https://github.com/tensorflow/lingvo). This is the open source release of Googles internal ASR system, and used by Google in production (their internal version of it, which is not too much different).

* NVIDIA OpenSeq2Seq (https://github.com/NVIDIA/OpenSeq2Seq).

* Facebook Fairseq (https://github.com/pytorch/fairseq). Attention-based encoder-decoder models mostly.

* Facebook wav2letter (https://github.com/facebookresearch/wav2letter). ASG model/training.

* Vosk (https://github.com/alphacep/vosk-api). Offline lightweight speech recognition API with support for 10 languages.

And there are much more.
Your new explicit definition of reality is different than your old implicit definition of reality. There are presumably more things that "don't go away when you stop believing in them" than "what outcomes of experiments should be."

What people want to know is what doesn't go away when you stop believing in it. What you've claimed so far is that the results of experiments (i.e. effects) don't go away if you stop believing in them. This isn't controversial; however it is incomplete. It doesn't tell us what caused the effects. If many-worlds, for example, is true, then when you stop believing in it then its branching and branches will not go away. If pilot-wave theory is true, the pilot waves do not go away when you stop believing in them. If objective collapse theories are true, wave functions spontaneously collapse whether you believe so or not. You, on the other hand, are only accounting for effects and models, not causes and what is modeled.
If you don't have a product yet, following "best practises" is not a good use of time, especially if there's no consumer facing impact and if it takes you twice as long to do it. Unless you are developing niche hardware or safety critical products, your first release must be quick. Time is the most valuable asset you have, don't waste it on formatting/linting/CI-CD at this stage. An early release puts your product in the market and allows you to get feedback from that point, which is quite valuable to an early stage startup.
Remember that you need something in addition to s-expressions to represent a dictionary. (There are multiple ways to do it but at the end of the day all you have are nestable lists.)

I think there were two elements. One was that gay marriage suddenly started happening in many places around the world and instead of dire warnings coming true, all the public heard were media reports of some happy couples getting married. The other was generational shift: a generation who had grown up when homosexual relations were unthinkable where even many left-leaning people felt the natural order was being disturbed and Something Must Be Done was supplanted in numbers and political influence by a younger generation where even most conservatives didn't exactly see the gay people they knew as a threat. (And in some parts of the world, the Right even flipped the whole thing on its head and used "their homophobia makes them not like us" as an argument in their campaigns against immigrants or religious minorities). In the middle, lots of people's views on marriage turned out to be a lot less strong than the conservative culture warriors had hoped...

I think it goes to show that conservatives can generally rely on younger generations becoming more receptive to their arguments about tax and security and Chesterton's Fence (and less interested in provisions for people on low incomes) as they age to compensate for older conservatives dying off, the switching sides in culture wars tends to trend in the opposite direction.

I agree with you, but as a non-expert in the matter, I have to add that banks are heavily regulated in that regard and have to deposits certain reserves to central banks (depending on the country) for that privilege. It's not that they operate differently than LLCs while having the privilege of insurance. They pay a price for that privilege, and we can argue whether that price is too low or not.

It might add some overhead, but I guess it depends on the page implementation, but 16 bytes seems to be the minimum (and Optane Memory might , I agree. That said if someone changes only one record the best thing is to write in the smallest granularity possible on the storage medium.

So, it might well be that someone is only interested in only one or a few records. Why then fetch and cache a whole 4Kb page if latency is good in both cases (4kb and 256 bytes)? On the other hand I agree that you should probably cache more data from a hot page.

The problem I find with this entire segment of the industry - is that nothing seems to work as I grow and change. Everyone is actively trying to achieve vendor lock in. It's true for Evernote, OneNote, Notion - and all the other things too.

To make it worse, none of them are better than pen and paper. I want the ability, from my desktop to clip sections of pages, capture pages, annotate them, etc. I want to have the same experience on phone and tablet whether iOS, Android, or a mixture thereof. I want to annotate with notes, that I want to remain as handwritten notes, but be legitimately OCRed for the purpose of search. I don't want to click anything to make this happen; on a tablet this means just write and go. Rocketbook is the closest I've gotten to that, and it was still unbelievably far away from the goal set.

So now, I'm back to pen, paper, and OneNote. I hate it - but it's currently (and not two months ago) the best answer for me.

I have no relation to either Fedora or RH, but have gone through quite a bit of their mailing lists in the past few months.

Drone isn't necessarily a quadcopter. It can be an RC plane, too, and those can be cheap in larger sizes, although they are more difficult to fly accurately. I'm actually surprised this isn't more prevalent - any teenager could do it, if they had access to explosives, which teenagers in war zones (current or past) typically do. And so do adults, of course.

Truly we are blessed with unequal distribution of technical skill between the terrorists and the rest of us. If a real, world class engineer took up terrorism, they'd never be found and could do _a lot_ of damage.
I think most HN people know Google is essentially a dumb search engine.

We're not surprised when image results have no correlation with the search term. The problem is when other people fail to notice this disparity.

They'll go on to write articles and blog post based on google's results. Later someone else will make a wikipedia page based on the blog post. Google's flawed results will now be confirmed by the wikipedia page.

A virtuous cycle indeed.
Splitting 100-lines-long function into let's optimistically say ten 5-lines-long functions is only a win in readibility if you strongly restrict the number of ways in which these 10 new functions can be combined (by scopes, typing, good naming conventions, etc.).

If you just extract the functions and change nothing else - you have 50 lines of code to read instead of 100 but you have 10! possible permutations of these function calls instead of 1 to think about.
> Ignoring the fact that meltdown is not even possible in modern designs

You realize this claim (of molten salt reactors) is mostly untrue, right?

It's true in the sense that the reactor itself can be drained into a drain tank, but this itself remains highly radioactive and liable to leakage.

It also produces radioactive Tritium which is difficult to contain.

> Hierarchical governance seems natural to us, pretty much written into fabric of social reality.

Hierarchies have existed for basically forever and it's almost always the natural state of organizations not just for humans. I wouldn't argue the opposite. What has changed and almost certainly will keep changing is the nature of these different hierarchies. Moreover, we have more than one single type of hierarchy co-existing. Just compare Switzerland to China in present time, or compare the independence of Hellenic city-states with the growing centralization of the EU and you will know what I mean.

The one thing that is recent (and IMO misguided and/or totalitarian) is the idea that we can organize ourselves into one single global hierarchy, an all-encompassing entity that would be able to subject all different countries into one unified set of rules. Some look at Europe and the EU as a way to show that would be a good thing, but completely ignore the fact that the EU it is not an unanimous organization. Libertarians think that all-out globalization and absolute free-flow of commerce will smooth out every international issue and will completely ignore the fact that this only works if every one is on similar level of individual freedom and economic development. Communists refuse to accept past failed attempts because in their view Communism can only work if the whole world adopts it.

Every Utopian project that requires every one to conform to one single set of rules has failed and will always fail due to the impossibility of satisfying the needs, values and wants of everyone at a global scale. I hope we can agree on that.

> Once a group reaches more than couple dozen members (...) you need to create a level of governance in order for the group to grow and stay coordinated.

Right, and the beauty of blockchain is precisely that it solves the Byzantine Generals Problem. You can have any number of people that don't know and don't trust each other able to coordinate without any central authority.

Granted, this is not a perfect solution. It's not like that just because we can have a computer network telling us "who controls X and who should have access to Y" that people will blindly follow it. You will still have groups trying to control things by force, abuse the system and so on. Societies will still have to have their military forces.

The key difference is that now these disparate people and societies no longer requires nation-states to organize themselves. People won't be forced to swear allegiance with to one tribe or another just because of the place they were born, etc.
A phone network is no use - latency means it’s useless for visual realtime control of a drone and you could just store a gps waypoint route on the flight controller and save the 4g modem weight if you meant as a mission control mechanism.
