Everything that you just listed is basically how our current system works.

Accredited institutions can issue degrees if you pass their courses. There are various "grades" that bucket people, but as far as getting the degree goes, you just need to pass. Grading is at least ostensibly objective. Admissions to accredited institutions is selective, and colleges compete with one another for students.

The only two differences are price per class and "objective grading".

The former amounts to "what if we had our current system, except everything were cheaper". Which, I guess I have to admit, would indeed be nice. It'd be nice if healthcare and cars and real estate were cheaper as well. Not sure how to actually do it, though.

And for the latter, we've done that in K12 (standardized tests). Almost everyone seems to agree it's a terrible system.
The facial detection all runs locally in your browser using tensorflow.js and it's crazy that we live in a time that's even possible :D

But I do appreciate the feedback and will be sure to add a disclaimer and make it clear what's going on!
Isn't that also due to the reason that consoles, once sold, last for close to 10 years and the game developers have to design their games for sub par hardware. Since graphics sell games more, they spend most of their available computation on graphics and other areas rather than coming up with intelligent AI which takes a lot of computation as well. This is probably the reason why we don't have many big single player games.
"a bunch of comments like these that are earnestly misinformed about economics. "

" savings outpaces investment opportunities for many reasons (aging populations, growth in countries with stronger saving cultures, etc.), which pushes up the premium on assets."

The savings rate is not correlated with stock prices. [1]

"All other developed economies have lower interest rates, more QE, and slower growth than the US. "

No, they have similar rates per capita. US grows because it brings in more bodies [2]. Moving warm bodies from A->B implying a loss somewhere and again somewhere else isn't exactly growth. (I mean - yes, they probably can be more productive in America). But this is not an economic marvel.

The OPs statements concerning inflation of financial assets is very, very reasonable economics.

If It Makes You Healthy – A song parody on the Covid-19 virus
I think the idea is really great for private parties. Zoom and similar conferencing systems don't work well because either everyone is the same volume and it is just loud noise, or it mutes everyone but the loudest person, which kills lively conversations.

I really like the idea of being able to mingle, and "walk" around to chat with different groups, all at the same party.
Didn't someone made something similar using jitsi meet?
This is also how I've always understood the two terms.
There are different categories for everything. There's getting to the end of the game and defeating the end boss ASAP. For games with a completion percentage, there's speedruns to get to 100% completion rather than just getting to the end. There's categories for not using "warps", and others that allow using "warps" to skip levels.

Tool Assisted Speedruns (TAS) is a category unto itself. This involves running game on an emulator and making human-impossible precise set of inputs, often disassembling the ROM to find bugs to take advantage of. The Arbitrary Code Execution 'stunt' category includes one where someone programed Super Mario World by picking up items in a precise order (and time) to specify bytes, managing to write tetris and jmp to it.

Competitions are made up, so we can make up whatever point A and point B is, and the rules along the way. Timing going from a Ubuntu ISO to desktop browser with google.com loaded is one A, B pair, but there's so many different possibilities out there!
> That is true of general humanity; Europe and Asia and Africa seem no different to me.

That might be true on a micro level or interpersonal relationships (some of them), but in the bigger picture there a systems in place to keep everybody healthy, educated and provide shelter if you need it. Looks to me like those three points are privileges in America.

And on the debt: Ok, it seems like average student loan debt is around $29k [1]. That's still pretty much and depending on your job might take quite long to balance out. In Germany state-provided student loan ("BAfög" - you can also receive it when you start an apprenticeship) debt is limited to 10k Euro. That means: No matter how much you get, your debt will top out there. You'll also only have to pay one half back to the state, the other half is "a present" or an investment in the future of the country. Seems pretty smart compared to 29k.

I thought the big cadence emulators weren't made of mainly FPGA chips, but instead arrays of absolutely tiny processor cores that only know logic and branch ops.

Not that this makes a difference for the core of the point you're making, it's more an aside.
But if I have

if (test)

and run it through a prettifier I end up with

(Possibly I don't write a lot of c, and when I do I always use {} even if it's a single line statement)

In python if I had a similar mis-indented construct how could you possibly know if it is supposed to be a nested if statement or not?

I'm not picking on python I'm curious. My preferred language is clojure. I feel like the python whitespace is probably like lisp parens. It doesn't matter after the first week of learning.

But when I'm typing clojure in emacs I don't care about formatting my code at all. Emacs sees the parens and indents correctly for me whenever I hit enter. I could probably write all my code on one line, run it through a code formatter and get a reasonable result.

On the rare occasion I'm fixing some python when I start a new line I sometimes need to think about indenting and tab cycle until I hit the right depth.

Titanfall is a pretty good example of how to design good AI. Same goes for Age of Empires, I would say. XCOM, on the other hand, just increases the HP and count of enemies, which is a bad experience.
>>Conway talked about determinism (and free will)...
>>>Based on your comment, I found these...

The math is over my head but this really piqued my curiosity.

I watched the first video yesterday and am looking forward to going through them all. He really is quite interesting.

I'm sure I'll take in one of his other lectures afterwards, but I generally have a hard time following those so maybe these will help ease me into that some. His opening bit about quantum physics might have of cracked open that door a little for me.
My friend and I wrote an algorithm that uses linear algebra to reliably diagnose 3D print fails, before they get bad. The algorithm and data are all open and linked.

Our most successful algorithm correctly detected all prints and failures that we've tested so far. It uses a Fourier transform of accelerometer data, which means that it converts from a raw vector acceleration signal to the power levels carried at different frequencies of oscillation. Ultimately, we look at the overall trend in the frequencies of oscillation to calculate whether the print is beginning to fail.

We designed and analyzed three techniques for testing, and ultimately chose a regression on the frequency domain of accelerometer data. A commodity cellphone accelerometer was more than accurate enough, sampling at <100Hz.
> in my experience the best way to get better at compilers (I can't claim to be a wizard) is to just build a goddamn compiler.

Yup. In fact, the best way to start is to build a desk calculator, where you type in strings like:

4 + 6

and it gives you back 10. There was one in the old K+R book. A compiler just scales that up.
Labels will probably remain optional, since folders are better supported by IMAP clients and they've been in the standard forever.

The only service that does not support folders properly is Gmail and the actual problem with Gmail is that they're abusing IMAP folders for emulating their labels. Fastmail has always been very standards compliant and I don't see them abusing the standard without a way to turn the behavior off.

So I don't really understand the drama. Also note that a lot of users, including myself, are craving for labels ;-)
We're working on an (at the moment manually curated, rule-based) AI devops solution, generating build definition(s) and deployment scripts automatically. Deployment may be docker based, single-instance test deployments, blue/green, hardware backed production deployments and anything above.

You're picking the environment you deem necessary and affordable, and our solution will automatically create appropriate build + deployment scripts for you. We promise no lock-in, generated scripts are downloadable and executable on-premises.

Our working MVP currently supports Java/Gradle based backends and angular / react based frontends. Supported databases are currently PostgreSQL. Supported cloud platforms are currently AWS, Azure to come next.

Roadmap:

* Azure support

* Google cloud support

* .net core backend support

Our own platform runs using our own product. We're searching for a select few alpha customers (lifetime free, incl. support).

If you're interested post a public comment here. No public details will be provided. The planned public alpha launch date will be around September 2020.
I got my start from the Tiny Pascal compiler listing from BYTE Magazine in the 1970's. It was a complete compiler and interpreter.
QE1 did not work at all. And the Fed's 0 percent interest rates have distorted capital markets causing corporate debt to skyrocket. That alone is propping up zombie companies and this overleverage is what will make the coming recession / depression even worse than 2008. Note: the Fed is violating the Federal Reserve Act by using BlackRock as a proxy for bond purchases. So please do not tell me they are not corrupt. They're beyond corrupt.

Minikube vs. kind vs. k3s – What should I use? – Max Brenner
I'm not suggesting it's all bad. I'm just suggesting it's potentially an explanation for the high rate of death on ventilators.

Ventilators may be the wrong treatment because the low oxygen levels may be largely due to a process more like anemia rather than primarily due to lung issues. You don't treat anemia by putting people on ventilators.

We can't successfully treat people if our mental models of the problem are entirely wrong.

Current thinking is that CF is relatively common in some populations because it is protective against certain conditions and those conditions swept through Europe a lot for a while. CF is predominantly Caucasian and it's homozygous recessive.

So the current belief is that it's sort of like Sickle Cell Anemia. One copy of the gene improves survival against certain infections without being an egregious burden to live with. Two copies are a terrible problem that kill you at an early age.

About 18 years ago, not long after me and my older son were diagnosed with CF, my younger son -- who is only a carrier -- had Winter Vomiting. It was a very deadly stomach flu.

He spent eight days miserable and barely eating. I told him if he got dehydrated, I was taking him to the ER to get an IV. He had an IV once and didn't want it again. So once a day, he drank 32 ounces of water, had a few crackers or ramen and then immediately projectile vomited it all back up. But it kept him from ending up dehydrated.

Me and my oldest son felt kind of meh for like maybe a day and a half. Our gut doesn't work right. This stomach flu didn't thrive in our system.

So I am abundantly familiar with the concept you are talking. What you are saying is like that X Files scene where she says "The cold is the only thing keeping him alive." when they are trying to treat him for hypothermia.

But ventilators are apparently killing people and apparently not primarily due to antibiotic resistant secondary infection. This is a clue. We need to follow the clues and see where they take us.

The lung issues are the obvious explanation for low oxygen, but treating for lung issues isn't getting the expected result. Ergo the low oxygen most likely is due to a different mechanism. Logically, it's a mechanism more akin to anemia, which is basically a bottleneck on how much oxygen the body can absorb at one time.

That's where we need to look, I think.
I've always known this as flow field pathfinding and it can get tricky if you have a dynamic map or enough changing that you need to recalculate often. Here's a random article I'm sure I read years ago describing it.

Well, teleporting is a tough problem to solve to begin with. One way to solve it is to have enemies distributed uniformly and restrict their movement to subsections. Once the player teleports, only the enemies in the closest subsections will use the algorithm to reach the player.
Yeah it doesn't need to be long (short is actually better as more chance of people reading it through)

1. The app requests permission to view your camera

2. Your video stream is displayed and a local js script will run facial recognition (not against a database, just a binary "is this a face") and only then will it allow you to join the chat.

3. When you join the chat, your video and audio will be transmitted but will not be stored.

some people likely won't even read it and just click anyway, but for the curious and/or paranoid it will definitely be reassuring.

It is a great deal, millions of keystrokes and code reading impediments avoided over decades vs. one exception a colleague of someone on a discussion board had once.

That’s a 1000x advantage in my book. Not mention exceptions are often avoided with a professional editor with whitespace highlighting and indentation guides.

I think it's oversimplified because there would need to be a long explanation on what is meant by "self", which the commentor very wisely put in scare quotes.

To the parent: actually I think this "death of decoherence" pretty closely matches the Buddhist doctrine of interdependent arising, so not sure about the disagreement there.
Cool!

I was playing around with my lil asteroid sim[1] and I wanted to trace the trajectories of the asteroids, so I put a particle generator in the asteroid "base class" and set it to emit sixty particles with lifetime set sixty seconds, zero momentum and velocity, and unaffected by gravity. I bet you could adapt that to make a "scent trail", eh?

We know for a fact that some countries didn't need to shut down. Again, South Korea and Taiwan are examples. They are also denser than the United States, and less wealthy, and closer to the source of the virus outbreak. Yet they handled it much better.

By contrast, the United States is less dense than those countries, significantly farther away from China, the richest country in the world, and had months to prepare.

I find it unconvincing that the United States could not have rolled out broad testing and tracing if it had started back in January when the virus was known to be a threat. Even if you're right and all it did was buy time before an inevitable shutdown, shortening the shutdown would have hugely helped to limit the economic damage.
>Later, I took a much smaller grad class with Prof Winston that had maybe 15 people in it. We spent half the time reading and discussing great AI papers.

The increasing volatility of future economic prosperity in most places, as well as concentration of burgeoning businesses into a few select cities is not factored into the CPI, and is probably not able to be factored.

The difference in probabilities of future life outcomes for living in certain prosperous neighborhoods and cities and the compound effect of children growing up in those is very material nowadays. This especially effects how much more housing and land costs in certain cities, and how much people are willing to gamble on it by leveraging more to "buy in" to those probabilities of future success.

JSON Spec for YAML files is neither ideal as there is no standard way to indicate, within the YAML file itself, which JSON schema to be read by parsers and editors to validate the document.

Sorry, but YAML is a disaster and YAML Lint and JSON Schema are weak attempts to improve it.

I'd be happy if YAML evolved to a true schema support, use of brackets or some other tip so white space wouldn't be meaningful, and silly things removed like three hundred ways to define Boolean values.
The issue more is about feedback and getting a proper system in place that we can all (multiple people in one car) chat with everyone else in other cars while the movie plays over the transmitter. The simple solution of calling into a group hangout and setting speakerphone is that we quickly get feedback from the audio of the move from the other cars.

Therefore they should be compensated too, and they are going to be. They get unemployment benefits and Federal money. The income tax due date was moved out, and many states have allowed people to stop paying rent and prevented evictions. There will probably be more help for people in the next relief bill the government passes.

People aren't being helped enough, but neither are businesses.

On the plus side, helping businesses can help people keep their jobs, so if you help businesses you also help their employees. People are focused on stock buybacks, but what we really ought to do is prevent businesses that receive aid from laying people off. (Of course, that does create the incentive for businesses to lay people off before they get the aid, but a smartly written law could require companies to hire those people back as a condition of aid, etc.)

Not necessarily a myth anymore, strangely. If you apt/rpm install something nowadays, it probably wasn't built with support for newer CPU instructions (AVX, AES-NI, sometimes even SSE4). -march=native is gonna have a much bigger effect now than stage 1 Gentoo installs did in the mid-2000s.

AngrySkillzz: you're trying to sound informed, but you're not.

Economics is known as the "dismal science" for a reason, and your ECON101 rehash doesn't help anybody.

Stocks have a high PE today because interest rates have been low since 2008, so investors have no choice but to buy real estate or stocks.

Most European countries don't have functioning economies, so buying on Italian or Spanish exchanges is pure speculation.
We're talking about bootstrapping to more usable tools, not about whether this hack fully replaces the standard feature. 'cd' certainly comes before command history, for example.

Incidentally you could take the same approach to some other shell built-ins, like redirection. Instead of `cat foo >outfile`, define a program named '>' and then say `> outfile cat foo`. (Assuming the initial bare-bones shell parses '>' as just another ordinary character, not special.) Use these until you've written a more featureful shell.

It might be interesting to figure out a design for a shell where this decentralized approach works well and does not feel like a kludge -- I imagine you'd have to change some deeper aspects of the OS design to really make it work.
I only read a little bit of voltpwn, but plundervolt is really cool. In one of the attacks, a fault is caused in the RSA scheme initialization, leading to reduced strength that can be broken. I guess a similar attack is possible with AES, but i dont understand it as well.
