>But that's also the problem; all this referencing of the ancient world culminated in Fascism (named from the Roman fasces, the bundle of sticks with an axe that symbolises judicial power).

That's a non sequitur.

"All this referencing of the ancient world" gave us the Renaissance and the Englitenment. And in tandem with the influence of christian morals, ended up giving us human rights, the respect (instead of contempt) for the powerless and the victim, and so on.

"Fascism", on the other hand, was an isolated ideology, it only really took off to a signficiant degree in Italy and Germany [1], and had nothing to do with the ancient world (although in the german version it had a fondness for paganism).

[1] While Japan was an Axis ally, theirs was just a plain-old nationalism, it had nothing to do with the ancient Greco-roman world, and also nothing to do with the economic etc. politics of Italian fascism (whereas German national-socialism had a lot in common with it). As for the rest, modern historians don't even consider Franco's Spain as fascist.
I was just ruminating with a friend the other day how much I want a typed lisp with Clojure syntax and semantics, and TypeScript’s type system. This checks one of those boxes almost entirely (syntax), and it makes me wonder if it could be wrapped or retrofitted to provide the rest. Probably not the type system without significant work. Still, cool project nonetheless!
I by no means advocate for keeping bad employees around. quite the opposite.

My point is that there's no reason to somehow induce your company to have more bad employees by watering down interviewing. Literally no upside.
With compression you avoid the cost of having multiple instructions to fuse. I don't see what that isn't a good combination.

With two instructions compressed into one and then fused into one micro-op you get both less pressure on cache while still getting high throughput in the micro-op execution pipeline.

The "killer feature" here is about designing the ISA around the fact that one knows macro-op fusion and compression exists.

E.g. x86 ISA was designed without any thought to the possible existence of macro-o fusion.

ARM seems to also have mostly ignored the existence of this in high end processors when designing their ISA. Innovation is really just about using existing stuff in clever new ways.

Btw Macro-op fusion and micro-op fusion are not the same thing.
I don't think that's what they mean when they say condescending.

I never had a chance to experience the creative side of Miami before moving out of my parents'. Sad to see its timeline is being shortened.
With infinite energy, Israel could have infinite water. They already have unlimited light and land. This is an energy intensive technology.

So, the question is whether it uses less electricity to desalinate and flood irrigate, or pay for the electricity to allow ultra high density, water efficient farms, and then desalinate less.

(I’d be shocked if either of these approaches is pareto-optimal.)
Why? Everything to run one of these would be cheaper in India (for example)...

Most of your points are solid. However, Variety could be a huge win. With the full-auto farm there is room to try out different types and experiment in small batch with tight monitoring and control which can also give predictable yield.
This is a pretty first world-centric perspective. There are slightly higher rates of dissatisfaction and hopelessness but quality of life is drastically improving in the second and third world. More efficient production results in better and more stuff even if the stuff isn't distributed perfectly.
Err, "custom MMUs made of individual logic chips" is what I meant. The MMUs are custom, the logic chips are just of the 74 variety.
Good point. I had a cross project issue come in to a small project of mine a few years ago. The maintainers of the other project actually brought up their much larger number of stars to (try to) belittle me. Since that day I’ve noticed the correlation between stars and the kind of response I’m apt to get, negative in both senses.
I know, there was a bunch of comments talking about that already, I just figured i'd throw in my own experience from the time rather than add to the echo chamber.

Nice, so this setup requires 18 raspberries for 30 USB-3 hard disks, 2TB each. I know this is about hacking and fun, but I wonder if there's no more better, certainly more traditional way of attaching these external disks to some powerful computer. What about a single server and attaching them with USB-3? Power consumption will be comparable with idling processors, but I assume the overall performance will be better with a traditional x86 desktop or server processor.

I’ll sit there staring at the wall for minutes at a time just running through narrative in my head.

I’ve never really tried verbalizing to myself, but I’ve effectively gotten over problems by rubber ducking with a peer, makes sense that it would work talking to myself as well :)

This is pretty cool. I'm always mashing the up arrow, so I installed this in anticipation of making my life easier :)

I didn't have `cargo` or any other rust language support installed. However, that seems pretty straight forward: https://www.rust-lang.org/tools/install

You may want to throw that into the README.

Anyhow, I'm running this on WSL2/Ubuntu 20.04 using zsh + ohmyzsh. It installs cleanly, and I just added `alias hh=hstr-rs` to ~/.zshrc as the only additional step. Works nicely!
You probably aren't paying tax on the tractor, but you are paying thousands in tax on your land and house. Then you do have equipment costs of the tractor, capital expenditures, etc. So you also need to produce enough to sell to cover some costs.

Also, you can't grow more than an acre of wheat for self-use legally in the US anyways.
There is something very creative about thread hijacking as well.

A Time Of Gifts is a marvelous book, I have a copy by my desk, but I'm not sure how one could read it and come away with a notion that fascination with the ancient world culminates in Fascism. The author is hugely engrossed with classic literature even as a teenager on walkabout -- the passage where he frightens a passerby because he's solo-reenacting scenes from epic poetry rather too enthusiastically, to keep himself entertained while on the trudge, is very memorable -- and it wasn't long after that journey concluded that he volunteered to go fight Fascism in the most literal sense possible.
First, thanks for the links. I have bookmarked the YouTube series. I too enjoy reading history and, as you rightly observe, most people don't go out of their way to read history. I am currently going through the Fall of Civilizations series [0] which I highly recommend.

The central point of your original comment was that there is extensive historical information available connecting us to our past but one has to put in the effort to discover it. You provided links to support your point.

This point could have been made succinctly. Many of the sentences with italics come across as preachy even though you probably didn't intend to. They were also unnecessary to get your point across.

I think blame is one way it can go bad, but not the only one. The whole framing of a "root cause" is dangerous, in that it encourages people to look for exactly one thing, and then not look beyond it when they find it. It sounds like your organization does decently in that regard, but they're doing it in spite of the "root cause" frame.

Thats total wishfull thinking. - you can only do that in specific niches, with significant capital outlay, near a city. You are not going ti make any money off an average 1-acre field in the countryside
He means the fall of Rome and organized state, and the regression due to barbaric attacks during the middle ages.

It took several centuries for the germanic, etc. tribes that defeated Rome to become civilized enough to Roman standards, and build equal structures and quality of life.

(As a point of comparison, Egyptians, Greeks, Romans, etc. had centuries of written history, whereas e.g. the British written history starts with the Roman invasion of the island, and starts by Romans).

From Complexity to Perplexity
TSLA? Not justifiable from a pure numbers standpoint.

But - other tech stocks? Arguably justifiable. Since the risk free rate (treasuries) has cratered, this has altered the DCF calculation that analysts use to value a company (the outcome is essentially this: the company is worth more, because this risk free rate is used in discounting the PV vs FV of the company’s cash flows).

Thus, it makes sense to have companies worth more (compared to historical price-to- earnings comparisons).

Then on top of this, there is a somewhat deflationary force of tech companies providing more efficient means and processes to things - which further perpetuates the cycle of these companies being worth more (their inputs cost less and are less labile, and their outputs are greater than say, a mining or oil company)
Anecdote - I find letting spiders live and using no insecticide results in fewer insects and more diverse and plentiful bird activity.
While I can't make a general comment, for some applications such as videogame engine development, std::unordered_map for example is not a perfectly fine class. Its linked-list-based memory layout means it is extremely CPU cache-unfriendly, making it incur an inordinately high amount of cache misses. [0] As you have a budget of 6ms per frame for 165 FPS, and you often need to iterate over many thousands of entities in each frame, std::unordered_map for one is a non-starter.

In general, when discussing which language features to use, I would keep in mind that something can work well for an application that is fairly straightforward and has modest performance requirements, while being a complete no-go for a different use case. I'm not saying we should throw C++ in the bin, but I also think many people have their reasons for saying some C++ features are more trouble than they're worth.

Comparing revenue with added value makes no sense, either. Makes more sense to look at profits.

After all, a company buying A for $100 and selling A for $100 will boost revenue, but will not see profit rise. A country in which companies buy A for $100 and sell A for $100 will not see GDP rise.

Yes, I'm the same way. If I have to keep everything verbal, I have to rehearse things or I'll lose them. Writing them down lets me externalize that.
I wish I could post this anonymously but I talk to myself during periods of intense problem solving and meditation. I maybe the only one that can answer technical problems I'm having sometimes with my own faults being the cause. Without a thorough review, tracing back probing to their source I'd be unable to continue with complex and obscure problems. In short only I have the answers to my problems as many problems are self caused. I use self speech as a way of forcing my brain to put vague notions into words so they can become more like reason and easier to pursue or reject.

I grew up alone, I had no one to talk to about things which are interesting to me.

I also sometimes have pressured speech, a psychological problem of an unknown origin. But treatment keeps it in check. I have just learned to censor myself when around others.

This is a terrible question to ask without context. Please provide context.
Every single person has no simple way to save money anymore. Savings accounts, CDs, and money markets - even high-yield online ones like Ally and Goldman Sachs - pay zero interest or close to it. Simultaneously the government has printed an absolutely incredible amount of money this year that has almost exclusively gone to the wealthy. This is because the fed is buying treasuries / corporate junk bonds and backstopping our entire economy while the actual economy has shrank maybe 10%. A tiny amount of the printed money is airdropped to citizens with direct checks or extended unemployment but this is a tiny amount that is primarily to buy off the commoners so they don’t complain about the enormous wealth transfer happening right now.

What this means is scarce financial assets are going to go up, and up, and up. Every person who doesn’t want to lose money needs to become a risk manager and start investing because there is no other option.
You really don't seem to know how the physical world works. And your "military grade" requirement is utter horseshit, as things break all the time in the military...
Agreed, but it should be possible to read and understand. This is solidly neither.
Maslow put "employment" in his hierarchy of needs. As a trust fund kid I've never had to worry about living in the streets but found that without the purpose of work I felt pretty worthless. If you live in the first world you basically have food water and shelter taken care of for you if you're resourceful. The rest seems to be climbing status hierarchies and opulence.
Or maybe more traditional approach of greenhouses? Which should have relatively similar case of handling evaporative losses... And if conversion losses of Sun->EV->lights aren't too horrible, you could even cover these with solar panels... What is even the efficiency of electricity used by vertical farms?

Lords of Finance: The Bankers Who Broke the World
It's not a question of pioneering, it's a question of base resource inputs. Tesla can promise an electric car but they can't promise one that costs less than the lithium and metals required to manufacture it, let alone the cost of labor. Just like Tesla, a farmer can't promise to produce vegetables for less than the cost of fertilizer. Based on the foods that the world prefers to eat, it's just not feasible.

Take a look at the scale of fertilizer manufacturing and use in agriculture. The amount of power required to make that fertilizer is likely an order of magnitude or two less than the amount of power that the sun feeds into photosynthetic systems. Classical agriculture gets that massive power input for free by trading off land use, which also has important follow on effects for fertilizer use, compounding the advantage in fertile areas like California.

It's not like it's impossible if climate change gets really bad and we have to move underground with plentiful nuclear power, but it's so far from economically viable at scale as to be a pipe dream.
And what is the price for the produce in those areas? Less as well. In these areas, it's highly unlikely this system would be feasible if land costs are relatively low and energy prices are a relatively higher expense compared to incomes in higher earning countries (as a percentage of income).
It doesn't sound like there was a containment breach. Pu-238 is hot, that's why it can be used for a RTG. That doesn't mean it's frying you.

And it doesn't release more radiation than a bomb. Pu-238 is an alpha emitter--and alpha emitters can only hurt you if they get inside your body (or from simple heat--pick up one of those rods and you'll get burnt just like if you picked up any other hot piece of metal.) The decay product is U-234, also an alpha emitter and with a quarter of a million year half life.

Likewise, it's Pu-239 contaminant is an alpha emitter and decays to U-235, likewise an alpha emitter, this time with a half life of three quarters of a billion years.

You also don't understand about half lives--you get one decay per atom. If one isotope has a half life a thousand times as long as another you get one thousandth as many decays per second and thus one thousandth the radioactivity per unit of time.

A bomb converts material with a long half life into material with short half lives and thus greatly increases the amount of radioactivity.
I prefer to watch Nilaus do it on YouTube/Twitch, because his job prior to becomming a full-time YouTube content creator was leading an engineering organization, and got his degree in "Transport and Logistics".

He understands the problems Factorio is presenting, and the "state of the art" for how to solve them, and it's a ton of fun to watch what he focuses on, what gets backburnered, etc.

I for sure recommend his channel if you like to see Factorio as (IMO) it's supposed to be played.
It's cited at the head of the article, where his death is first mentioned.

I don't want to outright dismiss this piece as "argument bait", but it is essentially just a bunch of assertions on what other people should do with virtually no rationale and a bunch of shade thrown around deliberately. Sure, we all like to have a good argument, and C++ is an easy target, but this seems wholly unproductive from the get-go. If there was any intent of convincing others then this isn't how to do it.

I would also like to know who or what the "Orthodox C++ committee" is. A search only gets you this exact gist. Is the author himself the committee? That really doesn't put this piece into a better light.

Ask HN: Do all mental processes have a physical existence?
If a unique idea or concept is created by a mind, it undeniably exists (albeit in an abstract sense).

Does it then have a physical existence? Does it propagate into space (electromagnetism)? Theoretically, could an idea/experience be reconstructed from the private thoughts of an individual?

If all mental workings have a physical component, would that mean that there is an encoding mechanism for subjective experience?

I could be asking the wrong questions here. My knowledge of physics and neuroscience in borderline nonexistent.

Thanks!
>I honestly feel like if Europe didn't have the Early Middle Ages (~500-1000AD), we would feel pretty connected to all the history that happened before

Well, that's true for the western Roman Empire. The eastern side (which included southernmost Italy, Greece, most of the mediterrenean, middle east - Syria, Lebanon, and balkans, and eastern (modern) turkey) persisted, kept and advanced the Roman civic structure, organization, legal system, etc and didn't collapse during the middle ages.

That's why you find e.g. levantine people like Taleb that feel and express the whole connection of their area back to the ancient times...
Have you tried Nvidia’s GeForce Now? I would be curious to hear your opinion of it compared to the other similar services you’ve tried. I’ve heard the most good things about nvidias offering in this space.
This is somewhat exaggerated, especially because while there are several poorly designed areas in C++ and the STL, it's not all that bad and it can lead to safer, less fragile code than the C equivalent with less effort (but arguably, more skill is required in order to learn and proficiently use C++). It can even be faster than C in the hands of a skilled developer that knows where and how use the right features.

It doesn't hurt that the STL is extremely optimized, and often provides you tools that accomplish what you cared about without lots of the gotchas and pitfalls you're almost certainly doomed to fall for if you're not aware of their existence. Almost every single C project I've seen (including some of mine, I've to admit) end up involuntarily reimplementing some basic algorithm or container, and most often than not it ends up being less efficient, or unnecessarily using the heap.

One thing I think most people largely misunderstood is exceptions; they're actually totally fine if used in _exceptional_ circumstances, as if they were some kind of softer assertion, when you expect some kind of contract to be always true, but calling abort is just too unreasonable. This is basically the same approach Rust and Go use with panic(), and in both languages this facility by default causes the runtime to unwind the stack, as with C++ exceptions.

I think lots of people have been turned off by certain bad designs in older C++ revisions, where exceptions where indiscriminately used for error handing. They were a nightmare to use right, and the lack of helpers like unique_ptr made exception safety very hard.

Modern practices, an arguably better language after C++11 and guidelines/libraries such as the GSL vastly help in mitigating most of these issues, as long as people actually stick to them (i.e., no C style code without RAII).

I may also argue that the whole "C++ exceptions are expensive" argument is 100% moot in 2020, I've been running code on microcontrollers with half a megabyte of ram with them turned on and they add an almost insignificant amount of overhead; they only cause a small amount of binary bloat, but that's nothing compared to the size of certain modern libraries (and storage is cheap).
