Bitcoin manages to perform ~7 financial transactions a second, whereas this 'proof of work' manages to assign jobs for ~300 million people. Some of those people even manage to learn something useful, and go on on to design things like Bitcoin and the power plants that produce electricity that is wasted by it.
10 decimal points reminds me of a conversation I had with my father. Last century my dad was working on radar/IFF simulations, and he had an anecdote (if you can call it that) about when they switched from normal to double precision, and needing to get more digits of π (I think from 10 to 20, the way he talked implied some very strange things about the programming language(s) he was using). The third time he told this story, late-teenage-me pointed out that the curvature of spacetime under GR had more impact than the extra digits.

While the broader point is valid, IIRC climate (being about average and broad trends) is fine with the imperfections, and handles this by running multiple simulations with slightly different parameters and seeing what usually happens. Weather forecast likewise.
Well, absolutely, and that's my original point. All the technology necessary to combat climate change is already there, but people aren't using it because it's marginally less convenient or more expensive.

completely disagree. The pandemic was the sea change toward mass videoconferencing. Zoom just surfed the wave significantly better than others, thanks to good marketing and a simple ordering process. (Ordering Webex has gotten better but I dare you to order it back in 2019 for example...)
In PRC's opinion, it is not colonial replay. Taiwan was returned to the China after WW2 officially, and the government that time was ROC, Republic of China, and there is no official end of the Chinese civil war, no peace agreement signed. Taiwan's independence party want to make Taiwan to be the front of containing China, which can only make the situation worse.

I don't like to predict, but I have to say a war will happen. Ever since PRC was founded, unifying China is part of its mission. There was a hope for a peaceful unification of some sort, it is long gone now. It is the reality now.
Are any external suppliers stupid enough to agree to this? Isn’t it basically writing you an unlimited cheque if someone hosting your data gets hacked?
> there isn't enough people around who have the skills and are willing to work there at any price

I don't believe it. They could easily expand their hiring if they were sufficiently motivated. There is a combination of mismatched incentives at the team level and inefficient interviewing processes and requirements.

It's often in the interest of employees to be inefficient in this regard.
> What there has been is a re-evaluation by workers of the value of their own work.

I think a component of this is hazard pay. The pandemic has made a lot of these low pay jobs more dangerous. If everything else is the same, but the job is now more dangerous, fewer people will take the employment.
To me it seems that those use cases would require a massive and rugged connector like the computer mains plug. Realistically I suppose the solution is to have some sort of a bag. For me when hiking or biking I always charge my phone in the backpack/saddlebag/front bike pouch. For the laptop on knees it might be preferable to have a plug on the back (usb-c charging has the advantage that it can have multiple options, at least right/left side. Another option is angled cables mostly immune to slamming from the side and somewhat resilient to angular momentum due to small size.

For chewed cables I agree. But again to actually make a resilient cable it would need to be thicker than most modern phones, the connector is not the weak point here.
Yea that's true, I am making a strawman too.

Whatever we do, it's bizarre to plan "poor people's economies". Whether it's creating internal economies, or sending some aid and wishing an external economy will materialize (but not compete with ours!), the truth is that we are at the same helping and exploiting the third world.
That analogy doesn't work for the Falklands neither, the only people ever living there are British. There never was a native nor an Argentinian population there.
Interesting. Does not tick all the boxes, but certainly interesting and, imho, very similar to Imba but with a bit more typing.
Another commenter pointed me to the obvious that it probably does come down to savings, which makes sense because I do already do those things. I do have a car, but thats from pre-WFH, so I could probably get rid of that now, and I don't go away for vacations at all, I just stay at home or at most go to a caravan site.

So yeh, might just be a waiting game.

Sounds like you're comparing multi-threaded zstd to other utilities that are single-threaded (e.g. gzip instead of pigz).

I duped /usr/share/dict/words into an 8GB file and did a couple tests on the old system I'm on:

8589934592 original
3075315128 pigz -1 1m0.44s

O(n) isEven function compared to the obvious constant time O(1) modulo algorithm

In the holy name of nitpickiness: the modulo operation is not always O(1), as div/mod CPU instructions have complex internal implementations and require varying number of cycles depending on what the input args are.

However, for x%2 it'll be probably O(1), both on the cpu level, and b/c it'll get optimized to something like x&1 by most compilers (at least for unsigned values)
I was trying more to cover the distinction between in-flight and at-rest encryption rather than imply that contents are routinely end-to-end encrypted now. That's sometimes but not always the case.

There is an increasing use of encryption-at-rest services (AFAIU Gmail is, though that's using a system-level, not user-level, key). There are some encrypted email services (e.g., Protonmail), in which contents are encrypted both in-flight and at-rest.

Not especially relevant to the anecdote here, but a critical concern for messaging opsec: email metadata, including sender, receiver, and subject, are not encrypted at rest or to the originating, receiving, and possibly transit systems, may also leak information, and are often more valuable and useful than contents themselves.

I find myself wondering if my correspondents who can't seem to provide contextually useful subject lines are actually doing me a favour, despite the annoyance factor ....
Looks great. What are the cons? Why should I not use it? Every technology has some.
I taught a module on tensors in my undergrad Mathematical Methods for Physics course last semester. The students had a weak mathematical background, so I had to explain better than any of the books and videos do.

The main problem with most introductions to the topic are that they deal with coordinate systems where the basis vectors are orthogonal, so the covariant and contravariant components are the same. You need to deal with non-orthogonal basis vectors, because then you realize that naturally there are two ways of defining basis vectors at a given point in space. And naturally these two different sets of basis vectors have different transformation properties under geometric transformations. This book [https://danfleisch.com/sgvt/] does a decent job of getting you started on this approach - of course, it has no rigor.
Resistance in push-in clamp contacts is a little higher than soldered contacts, and about the same as screwed ones. Consistency for push-in contacts is far far better: Cold and sloppy soldering just doesn't happen, loose screws don't happen. Corrosion resistance is worse both for screwed and push-in contacts, but the push-in ones are self-healing: just wiggle it a little and it is fine again. Solder does also age and corrode, but very slowly. Both solder and screwed contacts are prone to loosen and break under vibration and movement (which shouldn't happen when wiring a house, but relevant e.g. for cars). You can do aerospace-grade soldering, which together with proper wiring design to reduce transferred force and vibration, will be sturdier than anything else, but also far far more difficult and expensive. Soldered contacts are also prone to degrade quickly when heated, e.g. when overtaxing a circuit or the (sloppily done) solder joint, which can happen at less than the circuit rating. Push-in clamps keep the contact pressure even with heat expansion, movement and deforming ageing wires.

So there are specifics one has to be aware of, but in most cases, you want push-in clamps. Soldering is the only alternative, but isn't really viable without the proper skills of the worker and inspection of all solder joints.

How does LLVM know to simplify f^N ?

I've seen LLVM do the same optimization for triangular and pyramidal numbers. Is there a list of hardcoded functions it can handle? Does it try a specific algorithm to find the direct formula?

I don't think that would be much different than the UK invading say Gibraltar in 1704. I'm not going to advocate for it but if they did it, and held their possession for a few hundred years (content with what the capture did for their political posture) then yes, we'd be having a different conversation. Possession is 9/10ths of geopolitics. A few hundred years from now, the population of Taiwan would likely have a very different opinion of the matter.

At that point I suspect there'd be quite a lot of resistance to breaking them away from the mainland too.

This was also illustrated by Ubuntu by the way. When Ubuntu had the global menu ootb most of the Linux GUI apps supported it. A significant portion of the same apps don't seem to support it in other distros/DEs even if I configure them (the DEs) to use the global menu. I tried Xubuntu, Manjaro KDE and ended up using classic in-window menu set-up because many apps used it anyway and I want the thing to be uniform (the situation when some apps use the global menu when many use their own seems ugly to me).
Zstd by default is single-threaded. Just in case though...

It is just no match.

EDIT: axiolite wanted to see --single-thread and while my Linux box only has an older zstd (1.3.3) without that option I realized I do have a Windows executable for recent zstd (1.5.0). Both executables have run in the same machine but I can't guarantee anything about the 1.5.0 binary.
This is awesome. Understandably in museums you are not allowed to touch the old hardware, let alone run programs.

That being said if you want to get close to a remarkable collection of early computers I can recommend the Deutsches Museum in Munich, Germany. They have other models besides IBM, like the original Zuse Z4 and a leather covered Cray you can sit on.
>I bet most Uber Eats drivers make less than fast food employees, but I also bet they have less non work corporate BS to deal with, and outside whatever algorithmic unfairness can work as they want.

From my experience of seeing grumpy Deliveroo and Uber Eats drivers mouth off at poor fast food and restaurant employees when the food isn't ready yet, and the general way they drive on the streets, I don't agree with that sentiment at all.
I agree that company culture is something that goes top down and you do not change by simply swapping out the security team. Zoom has (had?) a culture of wilful negligence, taking dangerous shortcut (they are the only company whose mess Apple had to fix themselves with security patch for god sake – I still can't believe this one actually), etc.

I might be pessimistic but I don't think such a culture is something you can correct very easily, because it is anchored at the very top of the company.

Rust seems very popular despite also being bleeding edge. I am surprised there isn't more public industry interest in ATS, it looks very principled and well designed.
I definitely don't spend as much time doing chores as my grandma used to do before she had electricity. Recall that not too long ago "sewing your own clothes" also was a chore you had to do, and washing clothes took a whole day. Modern appliances made it possible for women to join the workforce because they freed up so much time.
As colonial power, they can issue passports for oversea citizens, it does not mean anything. When returning to China, citizens are given a choice to take whichever passport they choose. To fix a colonial problem, you need to have the power to confront them, British left Hong Kong, and Portuguese left Macau not because those details, because they couldn't hold on to it

As in Sri Lanka or Bangladesh, British still owns properties legally from colonial age, and they are able to extract wealth legally. They have papers, documents and everything. Does legal papers make it right?
Because maps can always be out of date?

It's common that due to construction, temporary road signs are placed to re-route traffic. It would be a disaster if the self driving car simply ignores them because they are not on the map, I assume?

It's a book review. ~10 paragraphs summing up the contents of a five hundred page book is bound to be fragmented.
zstd is NOT single-threaded by default. It's dual threaded. You have to pass the --single-thread option to make it single threaded.

I am no designer, but I would guess:

* underlined links in sidebar (we are familiar with sidebars now, we know we can click those, this looks like a page made with <frame>)

* same for top nav bar

* solid non-subtle background colors (more subtle ones or patterns these days are more common these days)

* too many font sizes

* odd intermix of rounded corners (very round!) and square ones

* unstyled textual header (if you just adopt a "visual" font for the title it will look nicer)

I don't mind it, anyway.

Like everything, there needs to be a balance. A healthy amount of selfishness is necessary for self-preservation, but too much is just greed.

Classic Economist to miss the story behind the story:

"The working-age employment rate (the share of 16- to 64-year-olds in a job) was at an all-time high in over half of rich countries."

Yes, because about half the population - women - who previously weren't counted as part of the "work force" are now counted.

However, looking at males alone, they have been dropping out of the workforce at an alarming rate: https://www.statista.com/statistics/191725/us-male-civilian-....

The Pandemic seems to be an acceleration of the latter trend, and perhaps a partial reversal of the former, with more women deciding to exit the workforce either temporarily or permanently.

Large corporation really didn't do anything lately to improve their image.

I opted for smaller monetary rewards for working in a smaller company with extensive freedom. Stress is mostly positive when projects get released. I have paid vacations and sick days, industry is secure that I can probably work until I get my pension if I wanted to. You also get much more invested in the company and other employees.

I still recommend doing a corp run for a year or two to get to know this world. It also help to negotiate your rates. But I don't see how you would not get a dislike about how things are done. It also seem to attract a certain kind of person.
The central idea of the black swan is that impossible events, as in 6+ standard deviations from the mean in a Gaussian setting, are far more probable because the underlying distribution was not Gaussian but one similar to a power law distribution.

The reason why these events happen is because humans simplify the world too much. I am an European. I see white swans my entire life. Hence black swans must not exist. Go to Australia. See black swans. Be shocked that statistics are essentially lies.

Our (humanity's) current understanding of gold is that it is scarce, hard to produce and it is valued by other humans. Thus under this model gold going to 100000x or 0.00001x of its current price is next to impossible. If it did we would think it is a black swan event.

But let's say someone out there finally learned the secret of alchemy and can flood the market with lots of gold making not scarce any more. For them the price tanking to 0.000001x is not a black swan but just business because they know the underlying reality. Also conversely if it turns out that only 0.0001% of the current gold supply is real while other is tainted in some way the price of the real could spike.

It is all about information asymmetry (human vs human) and naive simplification (human vs nature).

People usually buy gold to hedge against inflation of currencies. In a black swan case of alchemy this can be really bad but I guess someone at Palantir probably checked that the gold scarcity and demand is still a valid idea. Or not. People assumed the banks are good and we got 2007. Can't trust anyone.

No. Like I said, PE and PP - which are the vast majority of plastic packaging, especially for foods, because the materials you are referring to are not food-safe in the first place - are biologically inert.

In fact, the monomers of PE and PP (ethylene and propene) are also not toxic, which is uncommon (compare with e.g. PVC: vinylchloride is toxic in all sorts of ways, polystyrol: styrene is also toxic in a few ways and damages DNA, teflon: it's monomer is also a carcinogen). This is important, because making plastics generally leaves precursors in the finished product: the more the worse the process control is, which costs money and requires know-how.

See e.g. https://pubmed.ncbi.nlm.nih.gov/23862761/ for a study looking at whether these are EDC; they're not: "There were no significant differences between test and control groups in vagina or uterine weight. Data suggest that effluents from plastic food containers do not appear to produce significant adverse effects according to Hershberger and uterotrophic assays."

The single most problematic plastic for health purposes is PVC. PVC in its chemically pure form (difficult to do) isn't bad, either. But pure PVC is a hard, brittle plastic, which is not that useful. So most PVC products consist of a large portion of plasticizer; some products (e.g. cables and other types of very soft PVC) are actually more plasticizer than PVC both by weight and volume. Both PVC and toxic paints are a popular choice for all kinds of toys.
National Ignition Facility experiment puts researchers at threshold of fusion
Under little endian, the same power digits of differently sized operands are at the same offsets. For instance, whether we have a 16 bit operand or 128 bit operand, the least signficant 8 bits of either one are at the lowest address and so on. This is important if we want to, say, add them together.

However, this effect can hide bugs under little endian, which will instantly reproduce on big endian.

Suppose that, say, a function expects a 32 bit parameter, but the caller thinks it is passing a byte, whose value is XX. Suppose that by fluke the memory is all zeros. Under little endian, the caller puts XX at the right memory location in the stack, resulting in XX 00 00 00. And, by golly, the callee gets the corect 32 bit value XX.

Under big endian, even if by fluke the memory is all zeros, the caller will put the XX byte resulting in the same XX 00 00 00. But this now looks like a huge 32 bit value to the callee, hopefully caught in testing.

The apparently correct value will not be caught in testing.

Little endian would need nonzero values in the extra bytes instead of the fluky zeros in order to see a bad value.

In terms of rate of consumption of the overall address space, it's not. But consumers have started to have more than one device at home -- in fact almost everybody has an entire network with multiple machines these days, so a single address isn't sufficient.

v6 has enough space to give everybody multiple networks, not just multiple addresses (and those networks are always big enough for however many devices you end up attaching to them).

There's a hiring spree in Indian tech sector as of now, but that is mostly about folks changing companies at a rapid pace more than anything else. It didn't help that a lot of companies did not hire last year and all the open job positions had to be filled in this year. Companies being what they are, only wanted people with experience, bumping up the pay scale significantly.
I will nitpick your nitpick. In a language with arbitrary size integers you're right. This is a C++ int, therefore 32/64 bits (in all sane cases, ik the spec doesn't specify), so the maximum number of cycles is upper bounded. Therefore modulo on C++ ints is is O(1).
