"2d construction drawings are usually enough to reason about your mechanical problems and I wish there was an open source software that would augment the worklflow based on a pencil-and-paper metaphor."

Last year I was looking for something with the same use case in mind.
Quick 2D drawings, with modular blocks, and preferably open source.
The closest thing I found is qcad [1].

It has a lot to offer, but not everything is intuitive. So for me it was necessary to do a few of the tutorials.

There is also LibreCad [2]. A fork of qcad, which looks more modern (I did not try this one).

Still I did not yet find something that "augment the workflow" of the pencil and paper metaphor for mechanical applications. This would be really cool. Maybe even something compatible with the newest eInk devices.

Your skepticism is unwarranted - it's real. There's a documentary about it. Small droplets of rotting fat float up to the surface, where the dog can smell it. They had to account for ocean currents and the rate at which the bubbles rise in order to sufficiently narrow the search area. They couldn't find it at first, because they misunderstood the mechanism and assumed it was gas bubbles, which obviously rise at a different rate.

Besides - where else would they have gotten the information from? She was killed on a submarine with no one else aboard but her murderer, and he wasn't talking.
It would be a much better world for most Americans if the government wasn't spending lives and billions of dollars policing countries 6000+ miles away on behalf of other countries and foreign interests. Calling people who don't want to waste American lives and resources over Ukrainian soil to allow Poland and Germany a russia free buffer zone "russian bots" is a joke, most sane Americans don't want war over who gets to be installed as the leader of Ukraine for this decade.
Who establishes that sizing? I’ve yet to see anyone who can accurately estimate their own tasks let alone someone who can estimate that for others.

In agile, I think a great time for reflection is between sprints.

Also, I’m super fast but I’ll instead take frequent small breaks in the middle of work (read hacker news, write up documentation etc). There are other times to reflect than between tasks.
That's what Aleister Crowley was trying to do. His initial goal was to connect science and magick into a complete system. (He kinda devolved into crazy)

Why do some people feel it? Why do some dont? What is the nature of this "energy"? Can devices do magick instead of humans?

There's enough coincidences that should make most at least curious what's going on. It may be nothing... but probably isn't.

Wow - I've never seen this video before, I wonder if they had input on the visuals or if it was left to the compilation creator. Here's the full tape https://www.youtube.com/watch?v=XO3rLAs5Ee4 https://archive.org/details/futureshock3vhs

Seeing Lifeforms on TV is my earliest memory of a CGI music video: https://www.youtube.com/watch?v=kDSDeyfYJ5M

then they did videos for Cascade, Amoeba, Snake Hips pt 1+2, Smokin Japanese Babe, My Kingdom, We Have Explosive, maybe more.

I think most electronic tracks that charted in the 90s got a video? At least in the latter half.
This all pretends like there’s somehow no causality to many of these kids being “difficult”. I’ll even give that in some cases there is just some condition that makes a kid incredibly out of control despite actual loving supporting parents, but I would wager you can find environmental causes in most cases.

My experience with friends who have gone to places like this is that the kids by and large were under extreme emotional neglect from a very early age, and visiting a “troubled teen” facility is that it catalyses and forever imprints a childhood completely filled with trauma. It destroys forever the possibility of a relationship with the parents. Kids are often not told where they were going or being rushed away in the middle of the night, with drill sergeants and harsh punishments and rural facilities designed to present escape. It’s psychological torture to “break” a child as one would a farm animal.

Parents are sacrosanct in this country and there is no actual community to give much in terms of help. Peoples suburban homes are their castle and nobody knows how much neglect or abuse is going on behind closed doors until the kid shows up at school with a “behavior disorder”. Simply put: people who are completely incompetent to care for another human being much less an immature one’s emotional or physical or developmental needs get full legal protection. I think this is underappreciated in society since everyone who is a parent experienced many difficulties and they imagine all the ways things could go wrong. They are usually being charitable to the other parents though - the bar at which a child develops a secure emotional attachment is not that high.
I know very little about economics but I am compelled to point out the irony in your comment.

How I understood your comment:
"This whole field, consisting up of many people trying to do understand things, is just a bunch of nonsense generalizations."
I don't think there's much hope for people that go out of their way to insulate themselves into echo chambers. The key is removing the economic incentive for corporations to deliberately build these echo chambers and set them against one another. It's not that open federated systems will solve all problems, it's that a number of these problems will cease to be exacerbated. This may sound like a small thing, but at scale, the impact is enormous.
Android already has a sandboxing-first design. Every app runs in its own sandbox done via different Linux users. It's a bit crude to use a different user per application, but it's effective & robust.

Android is also pretty unapologetically POSIX/Linux and doesn't shy away from exposing that to applications (eg https://developer.android.com/reference/android/system/Os ). So I don't think Fuchsia would replace the Linux kernel in Android. It'd have to be far more rewarding a migration to justify the massive ecosystem breakages that would result (for both apps & OEMS)

Windows XP proved you can do it, but that at least came with a massive (real world) improvement to things like security & stability that were appreciable upgrades to end users.
>How do people even agree what things are worth in order to offer credit before there exists any prices?

This is prominently discussed by Graeber in the book, so this comment leads me to believe you have even read it.

>Things have been trending that way for a long while, but it really feels like the Orwellian knob has been jacked up an order of magnitude in the last 24 months.

Governments having much of a relationship with objective reality at all is a fairly new phenomenon and very much a product of the Enlightenment. It wasn't too long ago that court astrologers and politicised clergy were intimately involved in decisions that effected the lives of hundreds of thousands if not millions of people. What we're seeing is the erosion of Enlightenment rationalism into what we had before, the state saying 2 + 2 = 5 when it's convenient and browbeating anyone who points out how ridiculous they're being.

>If we can't agree on some basic rules about what is or is not true about fundamental reality, why even bother having courts or trials to determine higher level truths?

I'm sure this exact question went through the mind of Galileo Galilei when he was forced to recant his heliocentric views. Objective reality doesn't care about society's power structures, so society's power structures return the favour.
Many folks have often (correctly!) pointed out that each language's existing parsing packages will be more guaranteed to keep up with language changes. Our hope is that if we can get a critical mass of useful tools that all use tree-sitter under the covers, there will _also_ be incentives to ensure that the tree-sitter parser for each language stays up-to-date. And because of how tree-sitter grammars typically live in dedicated repos, that work might be done by external volunteers, and not by the core language developers.

Another benefit to our approach is that it should be much easier to adapt OP's linter to work with other languages, since in a sense it's “parameterized” by the language grammar and queries. If you use Python's `ast` module, you can't easily adapt that code to work on Go programs, for instance.
One problem with the walled gardens is they allowed themselves to be influenced/controlled by politics and public opinion "campaigners".

I worked pretty hard at getting promoted at my last job which unfortunately didn't happen. In the end I did the cost/benefit analysis of the amount of extra work I was doing compared to the 15% raise that I would get from being promoted.

In the end I moved companies and got a raise of about 35%. I'm back to doing the same amount of work I was doing before I tried to get promoted.
> Single address space OS's in a broader sense have been made unviable by Spectre vulnerabilities;

This is valid only for current CPUs and probably can be fixed. For example, current CPUs do not do speculative accesses for memory-mapped IO, and it means that similar method could be used to prevent access to kernel or other processes memory. There could be registers that contain lower and upper bounds of accessible memory, and they could be checked before accessing it.
I've read Lyn a couple times - I can't quite figure out their general position. Seems somewhat pro crypto and also all for deep dive in the financial markets / some kind of contrarian position. You think that's fairly accurate?

> how pervasive this music was at the turn of the century, it really was everywhere

Everywhere, except the United States.

I know, because I was a States-resident techno-head and I had to go "underground" to experience this stuff with others.

I don't know if it was the echoes of the disco backlash triggered by https://en.wikipedia.org/wiki/Disco_Demolition_Night (one of my earliest memories), but electronic music was extremely niche in the US at least until Deadmau5 lit up the Jersey Shore circa 2010. And to this day, if you go to certain places like New Orleans, any request for anything electronic will have someone redirect you to the "gay district" (the cultural/musical co-delineation is oddly strict down there)
I play Fall Guys and Warzone, both of which offer cosmetic modifications that are unlockable both through gameplay and by purchasing them. IMO, the cosmetics are little more than flair that add a little bit of fun and personal expression to the experience. Along with the "Battle Pass" model, where users are rewarded for regular play during content "Seasons", these mini-economies incentivize people to play regularly (which improves multiplayer games on a lot of levels) and incentivize the developers to continually add content. People that get these cosmetics enjoy having a distinctive profile in a social experience they spend a lot of time in and subsidize gamers that enjoy robust free experiences (e.g. kids/teens who provide a lot of excellent competition). It's all a win-win-win-win in my book.

I'm 41 years old and have fond memories of the old days of packaged buy-once games, but the modern battle pass/cosmetic standard seems like a much more realistic way of having a consistently updated experience with strong engagement year-round.

There's three players: registry, registrar, and DNS host. The parts that affect your availability are the registry's nameservers and your DNS host. The registrar is the control plane for the registry -- if your registrar is unavailable and your registry and DNS host are fine, you're still up.

If your DNS host is unavailable _and_ they're your registrar, then you can't make changes at the registry to use a different DNS host.

But if they're unavailable and they're not your registrar, then you can still make changes at the registry to use a different DNS host (although you'll still have to deal with the two-day TTL on the NS records at the root).

So the idea of using a different registrar and DNS host amounts to separating the control and data plane for your domain.
I was aware, and it is part of why I used them as an example along with the BBC. Like RT, they worked to create a reputation as high quality media funded at least in part by a national government.

I agree with the sentiments expressed by various others. 1) They can get rid of needing to use Linux, whenever convenient. 2) Possibly even replace Android too, if feasible or eventually. 3) Way more control, to make sure open-source "politics" doesn't interfere with their money, business goals, and exploitation of users info.

What I found most interesting was the sum convergence methods for multiple series.[1] Apparently with simple modifications you can improve the convergence rate of a multiple series sum by many orders of magnitude, making many multiple sums tractable which weren't before, using relatively simple identities that involve modifying both the summand and the limits of the indices.

Off topic: I like to think that combinatorics and statistics have a good-hearted sibling rivalry, both trying to explain what the other cannot but stealing from each others' crib notes all the time. That they meet in the middle with something as expressive as a calculus comes as little surprise.

I'm glad they talk a good bit about perceptions. That's really what it comes down to at the end of the day. Who cares if you're doing a lot of work or a little work if nobody sees it.

I don't know what's expected of me, at least not in an objective way. They apparently want me to go faster. One thing they are looking at is if I'm finishing early and asking for more work. So they are using that as an indicator, which is contrary to this article's advice.

I wish I had time to learn new skills. The work is so disjointed that you can never become an expert in one technology. Just constantly bouncing between systems, stacks, and languages. It's a mess. I have no desire to learn a new technology right now just because I know I will never get the chance to use it or become good with it.
Hardly. The whales are not always rich: often they’re just addict-type personalities who are extremely irresponsible with their money.

It’s not a healthy business model for consumers, but ever since I saw the start of this industry trend I’ve come to view consumers of it (in aggregate) as being of poor judgement if not outright stupid. So they kind of reap what they sew, and the rest of us must work harder to find quality. Just like in everything else really.
How would you disagree with it?
In regards to its view on math or on math education?
I have thought a bit about this and I see quite a few problems with his approach to the latter:
a) the number of students
b) the frequent lack of motivation of the pupils (which probably will never completely go away)
c) the lacking education/motivation of the teachers

So I dont really think that for large-scale education his ideas can be implemented, but that they are great for teaching your kids/friends about something.

But I do not see how you could not agree with him that the current situation is disastrous, since everything he said hit home for me when I was a student.
So I would really appreciate if you could point out where he is wrong, since a big part of my views about education/math are based on this.

The myth is that barter arose spontaneously throughout history and that currency arose as a more efficient means of mediating barter.

>I'm sorry, Adam Smith is left wing?

I was referring to Graeber. He was left wing and anticapitalist.

Orthodox (neoclassical) economists like Mankiw tend to be very strongly pro-corporate due to way funding flows in the profession.
It's great to see how others are doing serverless development. It's definitely not something you learn to do well overnight. I'm glad to see someone get past the learning curve and write about what works for them.

I've been experimenting with serverless for some time now and came to many of the same conclusions written about here. The biggest takeaway for me is that there are pitfalls to an overreliance on lambdas. You really need to offload as much as you can to the other serverless solutions AWS provides.

I've been using Appsync for my graphql API instead of API gateway + Lambda, and I have had a good experience with it. A lot of logic can be offloaded into mapping templates, making lambdas unnecessary in many cases. Debugging is still a bit of a pain for me, but the end result is fast, cheap, and reliable.
Do you think this was a factor when they decided to call bytes (data information unit) "octets" instead?
It's also an AWS-only tool, as far as I can see. As someone who's exploring more of Azure (due to choices of the company, where I'm mostly ambivalent on cloud choice), I have 0 use for something like this.

I'm currently working on using Terraform in Az DevOps Pipelines and Releases, to stand up an instance of something that has multiple 'cloud object' requirements. The Release process is frustrating, because the default assumptions made by Azure's tooling want me to format my variables a certain way. But, it would probably be like 'magic' if I just caved in and reworked our variables to be more Azure-friendly naming style.

Why should the tool have influence over the product? I know it's taking me more time to get it to work 'my' way, but I feel like I should force the system to adapt to my needs, instead of the other way around.
The GPT-3 API from OpenAI is only open for you if they approve of you. Anyone even remotely concerned with freedom (of software, of ideas) should not be using it.
Also single worker households, which meant there was someone to patronise those stores while the breadwinner was themselves working.

(To be clear, I'm not saying everything was great in the days of "all women are house wives" but it would have been nice if the stigma of a house husband went away instead, rather than the actual turn out of "both adults must work").
Oooh, a conspiracy!

Maybe the most important reason: If you are a salaried employee, the more work you do only cheapens your labor. And it cheapens the labor f your fellow employees.

One could argue that stock trading bots are already just that. Gives someone an overview of the entire market and performs transactions in matters of miliseconds.
Pffft! And what next, running software on fat clients? Preposterous!!!
>Barter involves agreeing on a specific exchange rate

This does not match with any definition that I've seen. Graeber debunks a parable used by Adam Smith and economists used to explain why money is more efficient than barter. The problem is that the central thesis of the parable still stands: trade is more efficient with through a medium of exchange.
