agree or disagree with the list, is is very USA-centric. As a US citizen I can look to all the events he cites and agree at least to their impact, but aside from the internet and Ukraine, these are all things that happened to the US. I wonder how important the assasination of JFK, RFK, and MLK, or 9/11 were to non-US citizens? (I'm genuinely curious, I know that the reach on the US means that almost everyone is impacted becuase we strongly impact other countries with our actions, but are they seen as turning points outside of the US?)

Yearn has more contributors than Bitcoin did at that point, tbh. I hate reading things like "Andre invented the fair launch" when, uh, that was clearly Satoshi, but as someone adjacent to Yearn, this isn't some random DeFi project.
The author does mention problems where LP solvers can be used to solve the problems instead of the neural network approach used for the others. See section 3 in https://arxiv.org/pdf/2104.14516.pdf.
BtrFS was previously restricted to crc32c checksums. This was enhanced to allow several more, including sha256. The crc32c checksum has also been improved as xxhash, which promises fewer collisions for safer deduplication. When configured for sha256, BtrFS uses a checksum that is as strong as ZFS.

However, the checksum must be chosen at the time of filesystem creation. I don't know of any way to upgrade an existing BtrFS filesystem.

Contrast this to ZFS, which allows the checksum to be modified on a file-by-file basis.
> meta-mathematics? Topology? Logics? History of mathematics? Philosophy of mathematics? Combinatorics? Number theory? Discrete mathematics? Graph theory?

Honestly all of those feel more niche than calculus. I agree with you and joatmon-snoo on the usefulness of statistics and would probably support bumping calculus in favor of statistics, but meta-mathematics, topology, logic (which bleeds into meta-mathematics), combinatorics (which is kind of covered by stats), number theory, discrete mathematics, and graph theory are all much less useful even in adjacent STEM fields (discrete mathematics and graph theory matter more in CS, but far less for day-to-day programming). History of mathematics is effectively an entirely separate discipline and philosophy of mathematics has meta-mathematics/mathematical logic as a prerequisite.

Calculus unlocks much of physics and engineering (and lots of stats!). Large cardinal theory does not unlock any other field to the best of my understanding.

The sanctions are being created for the world in which we live now. If you want to consider a theoretical world in which crypto is the main form of currency, you would also need to consider what kind of sanctions governments would impose in that world, not just assume that they'd do the exact same thing they're doing in the current circumstances.

How does an internet poll conducted by an organization working for an already jailed opposition leader overcome the polling-in-authoritarian states problem of people not trusting the polling not to be monitored and not to be a black mark in a government file if someone doesn't like the answer?

It doesn't provide a lowe bound on anything.
In a CBDC type system the Fed may or may not peg to an underlying asset. The paper does discuss the use of stablecoins as problematic. That likely means that the Federal Government doesn't want to peg your digital currency to a dollar or to anything physical. Without that pegging, they won't ever need to worry about a "run on the bank". Your CBDC will literally not be money, and any deposit you ever make for CBDC will have been a gift or maybe a purchase that won't be required to ever be reversed.

The C in CBDC is Central. The government wants this centralized not decentralized. They will be able to create any amount of CBDC currency.

The government will almost certainly push, along with this type of CBDC, for them to have far greater and more immediate control over your finances. In other words, any one of many government officials will be able to freeze your accounts (or drain them) at the push of a button. Hmm... I think that one of those three people did something bad - BAM - all three CBDC accounts are drained and frozen. Too bad, due to seizure laws, you can't ever get that back.

All of the advantages of having a physical note or a $ in a bank account disappear with this system. The government will control the ledger and everything that happens to it. There won't be money - just entries in the government's ledger. You won't be able to walk around with cash or even purchase an ice cream cone for your daughter without the government knowing.

That's in the best world. Just wait until the CBDC gets hacked like BTC or ETH. I doubt the government will return your govcoins.

PS. The document mentions "key stakeholders" in the CBDC. They aren't talking about people. You and I are not key stakeholders in this endeavor.

Your link show the opposite of what you claim. According to the main graph. Nuclear generation is not more expensive than other sources.

Also the costs at the output of the generator is one thing, but what counts is actually the cost of the useful power used. And renewables puts a lot of extra cost on the grid.
The term "transformer" is used throughout mathematics and computing. Machine learning hardly has the monopoly on it. Or should, for example, Haskell rename their monad transformers library?
I was using urbackup with ext4 and was having issues that caused corruption and couldn't figure out why, seen a recommendation to use urbackup with BTRFS and have had no corruption since.

The existence of shitty countries doing shitty things to their citizens is not enough reason to not do reasonable things in developed countries.

And again, f'ing crypto. This is the entire reason for crypto, to execute black market purchases (even if no one wants to make that the headline use of crypto). And if you think that your all cash purchases aren't being tracked, I have some bad news for you. If you walk into a store with a cell phone, you are being tracked, transaction and all. Facial recognition is going to be used the same way in those shitty countries (see China), so even going analog isn't going to save you.

There is no anonymity anymore unless you literally eschew all society and go live in the wilderness. Even then, it's not a guarantee.

Dang, well Cosmos was a large scale production so we have several people to blame for the inaccuracies. I understand 'The Dark Ages' is considered pejorative and onver-simplified. But there was an overabundance of religous magick being practiced across Europe as the time and I think he makes a lot of good points in the book that I have experienced in my own life. People going towards crystals, or homeopathic remedies for example. And to me that's not so far from these accounts: 'In England, for example, the King’s Touch was believed to heal scrofula, a form of tuberculosis. Prayers to Christ, the Virgin, and saints were always considered the most efficacious form of help. Saint Margaret was invoked for help in childbirth (47.101.65); Saint Fiacre (25.120.227; 17.190.353) for relief from hemorrhoids."

That said there is something for understanding a domain well enough that you can explain all of the major points of view around it. I got strong-armed by somebody on the bus into talking about the high price of gas, the war, January 6th and similar topics and after I got off I was praised by another passenger for being "incredibly diplomatic" for acknowledging the position of Vladimir Putin and Trump supporters while explaining why a No Fly Zone isn't a realistic policy.

There's a big difference between that and fighting for a POV I don't believe in.
The implementation details don't really matter: it's what the government can do with a central digital currency that's different than today.

Off the top of my head, here are some possible concerns and avenues for abuse.

1) Today, the government needs at least the pretense of a warrant or at least legislation to allow them to legally snoop into your financial affairs within a bank. Spying on you would probably be a lot easier for them on some kind of central digital currency that they'd manage. Want to buy a 12 pack of giant buttplugs or a Quran? Uncle Sam is going to know about it in our brave new centralized currency world.

2) Cancel culture and removing classes of people from the economy for wrongthink views, or even just actions that their politicians take on their behalf is already a thing. It's not hard to see a future authoritarian government making financial life for their political opponents hell.

3) Programmable centralized money allows central bankers to have unprecedented control to impose policy that would have been close to impossible to implement before. Keynesian thinkers for example view the idea of money flowing through the economy quickly as one of the big avenues to prosperity. It's not hard to see them clamoring for effectively a tax on money that sits in your wallet too long without being spent to promote consumption, or any number of experiments now that the tool exists to make it possible.
> and there is your arbitrary python code execution - which is exactly what we don't want.

The state of userspace sandboxing across all operating systems I'm aware of is dismal. As a developer it should be trivial to spawn a process with a subset of the privileges of the parent process.

Linux is better than most in terms of options, but you have to understand seccomp, namespaces, cgroups, containers, capabilities, etc etc. It's too confusing. Why can't I just say "spawn this process, limit it to reading files in this directory, writing files in this directory, this socket, max 10GB disk space, max 5% CPU, max 10% memory"? I'd even settle for just being able to limit filesystem and network access.

Even if you do manage to make it work, since the APIs require SETUID executables you might actually be opening yourself up to a bigger risk.

Someone needs to pull a WireGuard and make a small, simple API for userspace sandboxing. And please somehow miraculously make it so it is likely to be implemented by Windows.

love this question: especially about the distributed systems.

Something I've been thinking about, not necessarily in the interviewing world, would be to have a simulation of distributed systems for non-production code: in theory I think you totally could have a simulation layer for databases / server loads and test how your code performs in such environments.

I guess it exists in production: but haven't seen it for either a) learninga bout distributed systems, or b) for interviews
The thing about enterprise software is that sales are the hardest thing. Even if you had the perfect product already, each new customer wants their specific customizations before they sign that big cheque. This will not change regardless of how many features you have or how many customers are currently happy with the product. What should change is that the effort of making customizations should become easier as they fall into categories that you've done before.

As you company grows, eventually you may have the luxury of core product/feature developers and support engineers that adapt the software filling in those customer requested features. Until then priorities have to be balanced. But it shouldn't be your responsibility. If a particular issue needs to be raised because it doesn't seem to be getting sufficient attention then you can raise it and make as clear an argument for it as you can.

This shouldn't be for every one, and it shouldn't take all your energy. Things like you shouldn't be in direct communication with customers. There should be a designated support person(s) with understanding of the product use but not its implementation to record the issues that can be triaged, grouped, prioritized by a PM, and scheduled to be worked on.

Beyond that, it's common that developers will do incremental refactors or bug fixes (as time pressures permit) along the way when working on areas of the product.
Given the current geopolitical events, I'm note sure to understand how any country would agree to jump into the use of this CBDC.
My understanding is that with this new tool, the fed will be able to know where is the money in real time. Tough this makes a lot of sense from th FED side ( solutions implemented addresses in 2008 failed mainly because money received from th central banks failed to be re-injected in the real economy).

You can print a clearance tolerance test to see how accurate your printer is. I use a Prusa mk3s and as accurate as it is, at best my tolerance is 0.1mm. Enough to stop your parts fitting together. I normally build in a 0.2mm tolerance for close fitting parts.
That actually seems reasonable for the cost of a power station.

The problem recently is that privatized energy operators have a hard time securing financing in the orders of tens of billions. Wind, solar and gas may have higher per-unit costs but you can actually build one for under a billion dollars, and in the case of rooftop solar we are talking tens of thousands of dollars, and it is a lot easier to secure loans of that size. Tens of billions of dollars is basically reserved for the bond markets and state actors.

This. I think China's going to chase after after raw power and advantage, not a derivative like those things like money. Money is for little people to scramble after (and even billionaires are little people at the scale of great powers).
Calculus: I suggest just forget about "precalculus" and, instead, just get a good calculus book and dig in.

There are two main parts of calculus, and both can be well illustrated by driving a car. In the first part, we take the data on the odometer and from that construct the data on the speedometer. The speedometer values are called the (first) derivative of the odometer values. In the second part we take the speedometer values and construct the odometer values. The odometer values are the integral of the speedometer values. In notation, let t denote time measured in, say, seconds, and d(t) the distance, odometer value, at time t. Let s(t) be the speed at time t. Then in calculus

s(t) = d'(t) = d/dt d(t)

And d(t) is the integral of speed s(t) from time t = 0 to its present time.

Those are the basics.

Applications are all over physics, engineering, and the STEM fields.

Linear Algebra: The subject starts with a system of simultaneous linear equation. The property linearity is fundamental, a pillar of math and its applications. The STEM fields are awash in linearity. E.g., a concert hall performs a linear operation on the sound of the orchestra. E.g., in calculus, both differentiation and integration are linear. In the STEM fields, when a system is not linear, often our first step is to make an attack via a linear approximation. E.g., perpendicular projection onto a plane is a linear operator and the main idea in regression analysis curve fitting in statistics.

Most of math can be given simple intuitive explanations such as above.
I'm really hoping that this could be the start of a worldwide IP reform (both copyright and patents). The idea of patents (limited exclusivity for disclosure) makes sense, but reality has strayed far from it. Likewise, copyright with its obscene and ever-expanding protection terms and lack of fair use protections in most countries is in dire need of a reform.

However, this might also backfire by pushing companies more towards making everything a SaaS subscription service so customers never have any code they could pirate.
+1 on this. The env setup and test design along with a way for the candidate to submit their solution would save us a ton of work. I'd happily pay $30/interview just for that.

You're absolutely right that projects like these are silly as anything more than a fun tinkering exercise, but that 100-150W number is a low estimate. I'm fairly small and out of shape and can produce 180W for an hour. In-shape amateurs can do better than that.

Still not enough to be even remotely practical as a generation method, but substantially more than 100-150W

They don't need to immediately replace them. Russia has lost about a hundred tanks. They have nearly 13,000. They've lost about a dozen Su-27s, they have about 500.

And I'm a little more afraid for Ukraine having seen those civilian cars. It feels like Russia is going to start playing very dirty during the upcoming siege of Kiev. It sort of evens the playing field if the defenders also have to watch their backs everytime an unmarked civilian car drives by. It's a dirty move right out of Russia's playbook.

I've realized I'm mostly likely going to be one of those living archives, and I have very weird feelings about it.

I'm 33 years old and I might be the youngest person/in the very last group of people who remember the early Web and the pre-Web Internet (via 2 geek parents). Was I doing anything super important or useful? Of course not, but I clearly remember things like Eternal September, the first banner ads and discussion of their implications regarding monetization on the web, the browser and search engine wars (and the search engines replacing directories and curation). I clearly remember how excited I was when ANYBODY could make suggestions about what tags were going to made, etc. In short, while I was probably the worst programmer there (I mean I was 4-5, it's a decent excuse), I'm a decent primary source.

I'm also female and have multiple ancestors who made it to being supercentenarians; it's not out of the question that I'll be the last one left. (e.g. being around in 2100 to answer questions about the early Web, which by then will be shrouded in mystery or overly-sanitized narratives [especially the parts pre most things (or anything) being archived; a lot of the 90s are just not recorded at all.]) I'm also a librarian/archivist, and I spend some amount of time wondering what I should say.
