> One of the modern applications of Egyptian fractions is the request of a specific resistance value needed in the design of an electrical circuit, a problem called in the literature the 2- Ohm problem. College students know well from their physics class, that the equivalent resistance R of two parallel resistances and is given from a law very easy to deduce, based on equating the current passing through the fictitious equivalent resistance R with the two currents passing through both resistances while maintaining same potential. One direct application of this, suppose an engineer wishes to incorporate in one of his designs a resistor of so many ohms which the manufacturer does not produce; for it is impossible that the latter displays in the market all possible ohm-values for his resistors. First, the market cannot possibly sustain it, but more important, one cannot feasibly produce resistors with values as elements of a dense subset of the real line, being, as analysis taught us, an uncountable set. Rather, manufacturers display only in the market what they call an "E12 series", i.e. resistors in sets of 12 different values, namely

> 10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82 ......

> 100, 120, 150, 180, 220, 270, 330, 390, 470, 560, 680, 820......

> 1000, 1200.......... Ohms, etc.....

> Now suppose an engineer needs in one of his designs a resistor of 7 ohms, then he would resort to a parallel combination from the fraction 1/7=1/10+1/56+1/100+1/120+1/150 in which all the resistors belong to the E12 series, i.e. he will replace his 7 ohms resistor with 5 parallel resistors; this he reaches using a special software (computer programmes exist for such designs, yet the exact solution is by no means trivial). What I did myself instead, is to resort to Ahmes 2/n table and wrote 2/7=1/4+1/28 or that 1/7=1/8+1/56. Decomposing further 1/8 into 1/12+1/24=1/12+1/48+1/48, but then I shall have to use instead of the 48 ohms resistor a resistor of 47 ohms from the E12 table. My final fraction is 1/7=1/12+1/ 47+1/47+1/56, i.e. my resistor of 7 ohms will be simulated by 4 parallel resistors instead of 5 (I am accepting equal fractions). My solution is both minimal and optimal based on Ahmes table. The relative error of my design will not exceed 0.6 per cent, being negligible; especially that any manufactured resistor will itself be subject to some allowed tolerance of the same order.

Also:

> The measured values of voltages and currents in the infinite resistor chain circuit (also called the resistor ladder or infinite series-parallel circuit) follow the Fibonacci sequence. The intermediate results of adding the alternating series and parallel resistances yields fractions composed of consecutive Fibonacci numbers. The equivalent resistance of the entire circuit equals the golden ratio.
I had no idea there was an adaptation! Thank you for sharing!
Last-mile rural electrification will never reach everybody in the USA. It's just too many people to service. Roosevelt would've mandated free service for the poor for all new startups, among other considerations which would have made making a new a rural electrical utility a complete non-starter.

If you want Electricity, you can pay for it.

$90 if you're rural?! I'm now going to be paying $120. I live in a small town on the Navajo reservation. We don't have postal service, many here don't even have running water or electricity. The alternative ISP is 6 mbps max.

Any idea how I apply for this rural pricing?

They're a mild form of isolationism and nationalism and they can but do not have to be the first stage of a country moving further away from the center rather than a pendulum swing. With a pendulum the assumption is that it will move back but this sort of thing can easily move a country to the right and then ultra right, of which history carries a fair number of examples.
Sigh. Declarative condition expressions are not control flow, they’re part of the definition. They are part of “what” and you could not define anything meaningful without them. The mistake is treating:

if condition: a else: b

As equivalent to:

if condition: do a else: do b

They might seem very similar, but they’re wildly different if you actually have the constraint. There is an implicit “do” somewhere in any program that has IO, but having it mixed in with a declarative program makes no sense and can’t make sense.

In the SQL example, nothing happens if you reach the conditional and exit immediately. In the imperative example you have no way of knowing what happened without inspecting the resulting state, or the code that produced it.
You just have to be good enough to reproduce. If you follow the logic, 'the best' collapses into a tautology, where it is defined by reproducing (i.e., fitness). If there was really a singular "the best" and you had to be it to reproduce, at the individual level, populations would have a much harder time retaining heterozygosity and genetic diversity. At the species level, the only circumstance in which a species has to be 'the best' is if it has close to an identical fundamental niche (i.e., habitat and food requirements) as another species, because even given competitors for similar resources, there is often scope to occupy only a portion of the niche (i.e., abandon low elevation or certain foods), aka the realised niche, to avoid competition.
> People want changes, but few of them are willing to accept the personal sacrifices that come with such changes.

If by people you mean the average person, I don't agree with this line of reasoning, at least in the US. There's such a large and effective apparatus to perpetuate hegemony by corporate and media interests (in the Gramscian sense). I don't know if there's an effective mechanism for the collective average person to set the political agenda, and ironically the most prominent examples I've thought are the Trumpers (getting Trump elected) and QAnon (4chan conspiracy becoming so serious that it becomes a media talking point).
You are now mixing correct and conforming programs. Neither the C or C++ Standard mention anything involving correct programs. C uses the term conforming program and C++ uses the term well-formed program.

In C a conforming program is any program that satisfies any single conforming implementation, even if said implementation includes extensions or non-portable constructs. A strictly conforming program is a program that satisfies every conforming implementation, which implies that said program does not produce an output that depends on undefined, unspecified, or implementation defined behavior.

In C++ a well-formed program is any program that satisfies the syntax rules, diagnosable semantic rules and the one-definition rule.
System 9 was really just about some compatibility layers in preparation for OSX, as I remember it.

(And, yes, 7.6 was a major step in terms of stability. There was also some pre-PPC, pre-OpenDoc version of System 7 that was pretty stable, but with all those major integrations that came with the further iterations, things became a bit "delicate".)
> Do cheap launches help when spectral bandwidth over an area is going to be the true limitation?

Spectral bandwidth doesn't matter so much with beamforming with reasonably narrow beams. At least not until you get to a lot of satellites overhead at once. Dishy probably obtains a beam ~3 degrees wide; there's a lot of 3x3 degree sectors in the sky.

Similarly, the ground "cells" are 300 sq km; there's a lot of these in view of the satellite.

Yup, for the most part I agree. Still, there is a pretty large rural population.
English too, is a mix of foreign languages. Only dead languages don't evolve.

Italian is a descendant of the Latin language, which itself borrowed extensively from Greek. What is so special about today's Italian language that it should by all means be preserved in it's current form without continuing to borrow from foreign languages?

European languages borrow from English because the US offers so much that we voluntarily adopt in Europe. If most good movies, music, streaming services, computer hardware, computer software, Internet, electric cars, smartphones, AI, business ideas etc. were Italian, the English language would adopt more Italian words.

2. os.home()/.openai

3. Throws an exception telling the user to put it in one of the above, and then exits

best security is not obviously money. i wouldnt know of course, but there's a good scene that covers this in the first(ish) season of House of Cards: Kevin Spaceys character laments about otherwise excellent talent shortsightedly chasing the $$$ of the private sector jobs rather than strategically climbing the ladder of Capital Hill. All this to say, his point is broadly that influence and power can always find a way to money, money doesn't necessarily flow the other way through, not in every situation etc.
I don't think this is black or white. I've found out that brilliant engineers actually can be incredible people managers if you help them develop those soft skills.
Sure there is the age old adage that "I am a brilliant engineer just pay me more for my engineering work" but this has two aspects. For one you definitely can do it if your org is big and rich enough. But on the other side, software is a product of people interacting. If your engineering importance rises you still will have to deal with lots if people. So are you really staying purely an engineer then?
I think you are right. I don't know the real demographics, but anecdotally most buddies seem to have been looking into alternatives over the past few years. Some went for fancish Unraid, some various linux flavors, but very few actually stayed on Windows. Proton certainly helped as gaming stopped being a valid reason. I used to think my own jump will be harder, but, well, I now run Windows maybe once a quarter. One of those times is to file taxes.

Sadly, you are likely also right about the race to the bottom for the rest. Maybe it would be different if they cared, but they don't. I have tried to explain it to my wife many a time, but it was mostly a failure ( so now her new lappy runs decrappified Windows 10 ). Worse yet, the whole data economy has become ingrained. Just yesterday chick at a dealership joked to sign here so that everyone can get my phone number. After that, attended a birthday party, where host company had a provision in disclaimer that they can use any pictures captured on camera for their promotion should they so choose. I almost lost it. It has been normalized. And you can't even cross this shit out, because it is all 'standard form' on a PC and whatever teen is running the desk wouldn't give a shit even if they understood the issue.

I find it interesting that the article and paper which it summarises takes the analogy of representing steam locomotives as a species with a "driving force of survival" that far.

Steam Locomotives are simply a *product* in a competitive market, and that market changed.

If one wants to imbue them with all these biological properties, one can surely do that with any failed product? The Blackberry? 3D Televisions?

(Full disclosure: I'm a lifelong fan and studyer of steam locomotives)
Yeah obviously, but as long as the kid is interested in bulding an OS from the ground up, if he wants to do webdev, 3d design, music production, writing or whatever, it's just gonnna be an useless hassle.

And this comes from someone who spent a good amount of his teenage years toying with linux, arch, slackware, lfs, whatever. It was good fun but nowadays I think it was mostly useless and I'd rather had finished dev projects or whatever.
I remember hearing this back in the late 90s and I came into my high school biology class and mentioned it. The teacher was kind enough not to call me a moron but he made clear he didn't believe it, and I didn't (and don't) remember where I had heard it back then. Glad to know I wasn't completely wrong for regurgitating that factoid then.
Re-read the post you have been commenting on and point out where it says that managment isn't important.

What that post said is in fact that managment can be so important that it can't be left to people who are bad at it.
In in Paris right now and unfortunately it's still pretty bad. I'm sure there's certain arrondissements that have good access, but it's not the whole city, and riding on the road is so dangerous I only ever see delivery drivers do it.

Yea googling led me to this comment which led me to that wiki link. Very cryptic indeed but maybe that’s the point
Ok, you read the studies and are better informed than me. Just lay out how exactly this system would work, if:
1) Nuclear is phased out
2) Coal is phased out
3) We could at any time phase out gas as well because we semi-listened to the US that warned us we gave Putin the switch to our electricity grid

If I look at https://app.electricitymaps.com/zone/DE and see patterns like 50 GW at 3 am and 60 GW at 1 pm I wonder: how can you ensure providing the base output 24/7 entirely with renewables? I have seen facilities within industrial complexes that literally required more electricity than a whole city 24/7. The demand of electricity that needs to be provided 24/7 is enormous.

There is in addition a huge challenge to manage loads in a grid (that was never designed for it) for regional variance and unpredictability in energy production (e.g., sunshine in the north and wind in the north but no need there) and the consumption (e.g., industry in the south).

In classical “German ideology” fashion laws are passed, one-way door decisions are made, “experts testify” that everything works and 10 years later the thing blows up.

And it’s not just me who “brilliantly came up with this assessment” - but I borrowed it from publicly shared opinions of industry leaders:

And what about mac and windows? And X11 for that matter.
Pollution goes on because it's the convenient path of least resistance, has short term benefits (e.g. we keep indulging in consumptiona as usual) and there are huge profit interests. That simple.

How we see nature plays little role, in after-the-fact justifications or condemnations. In fact pollution could be justified under either view:

Humanity is different than nature: all we do is pollution, in the sense that is outside of nature. So why single any specific act out? Or other potential arguments: "We are better than nature, and we'll eventually just sort pollution out with our technology".

Humanitity is "just" nature: so what we do is natural, including pollution. No need to do something else, we just keep doing what comes natural to us, including polluting. Why consider huge heaps of human garbage any worse that we consider other animals creating their own waste?
>elegant neatness of the inside of a Mac

I get your point but this is pretty irrelevant to many people who want the machine to work. Function over form or some such. I'd rather have a durable, repairable machine than a "pretty" machine that allows me virtually 0 upgrades or I have to eat the cost of hundreds of dollars every time I have to send it to Apple care.

The thonkpads I have are fairly repairable, durable, and fast. Yes, they're bulky but weight is generally not an issue for me.
The M1 Max MacBook is the best computer I've ever owned, period. I upgraded to it from a 2012 MBP. The hardware is top-notch (pun intended).
This is not really true. While the base spec won't meet all needs, you don't need to max out the spec to get a usable machine with a long life.
Yeah sadly that's what they've started doing with the X1 Carbon series. But T(xxx) series is still pretty solid. Not to mention older x(xxx) units are still great.

> you'll struggle to find someone without a genuine fondness for it

I'm such a person. I realize that any kind of preference I have for the language that I grew up with is an accident of birth. It helps to be part of a country that is so small as to be irrelevant in the greater scheme of things. Life doesn't stop at the border and if you want to be active at all then you're going to have to interact with people speaking different languages. English, German and French to begin with, and maybe Spanish, Chinese and one of the Slavic languages after that.

I think English is here to stay in a way that Latin never was, the digital repository of English text is absolutely massive, unless you want to limit yourself you simply have to speak English. When there was no internet that meant books and once the printing press was invented and books were no longer in very limited circulation (and reading and writing became more common skills) written culture really took off. The Roman empire is what drove the spread of Latin and once the empire collapsed it took Latin with it, with the exception of some niche uses (science, mostly, and religious texts).
Thanks for the recommendation.

I hadn't heard about this book, and I'm always looking for new books that help frame problems better.

Just based off what I saw regarding this, its probably not the best as a starter book.

It can really be tough with this type of material because if you don't have a solid practical or rigorous approach to both logic and argumentation, and can reasonably make parallels or see where it leads, you can easily fall into traps that are plausible but may be flawed/false.

You really have to approach this type of material critically and assume its false until you can find rational and reasonable support for what may be said. Reading material in this genre, like you would a leisure book would be a mistake, since most tend to internalize words/concepts like movies after speed picks up, and of course children that have not yet reached the age of reason shouldn't be reading this type of material since they would be developmentally incapable of recognizing any potential lies for what they might be.

Not having read the book yet I can't yet vouch for the content, but it definitely looks interesting, and worth a read, at least for me.

You really have to know the philosophy and tactics that are pushed in this area in order to recognize it enough to defend against it.

There was a very interesting recent publication in USMC University on Political Warfare which has some overlap.
I am forever baffled by "à la mode" meaning "served with ice cream".
"rural" just means sparsely populated compared with dense urban cores. These people aren't impoverished, some of them are wealthy, most of them are middle class with property and acreage. Rural consumers are used to paying equipment costs, for example, they were among the first to adopt satellite TV, back when the dishes were enormous and you needed enough land to even mount one. And those cost thousands of dollars in the 80s and 90s.
What? They want the police to not do anything.
My father first introduced me to Linux (an installation disc he borrowed from his employer). It didn't work. It just didn't click for me, and I didn't know why my Dad would consist that I use it.

Fast forward a few years a couple of friends around my age introduced me to Linux; it was Ubuntu back when it was hipster and trendy and friendly. I started by dual booting (probably WUBI) and then switched completely.

This is just purely anecdotal, but my conclusion is that it just didn't work when a parent forces a child to do anything. Better to influence the social circle of the child so that the child can be convinced to learn use Linux from friends.
This is all well and good, but my state (Washington) actively uses specific AM stations for traffic and weather alerts. You will see signs on the freeways saying "tune to 750AM for emergency weather alerts now" (or whatever the frequency is).
