OTOH, being able to hit rewind is invaluable. Or hitting rewind, googling a bit, and then continuing. My first online course was Andrew Ngs when he at Stanford, and being able to rewind and google whatever he just said was fantastic. It also meant I could play it at 1.5x speed for the bits I had no trouble with.

If we wanted to make it better to support interactive questions, one could imagine an online system with videos plus "Push now for live help". Or facetime your peers.
Colleges, like Intellectual Property, impose artificial scarcity on the acquisition and dissemination of knowledge in an age where the Internet has allowed us all to publish and discuss like never before. They come from a time when we couldn’t record audio and video and disseminate it so easily. Never mind multimedia, they use heavy textbooks!

There is a concept called “flipping the classroom”, where people can watch the classroom lectures at home at their own pace, and do the homework together in class. And these lockdowns just go to show that people can carry on learning online. They just need a good coach or course.

Lectures are the commodity. Individual attention from tutors and labs is the scarcity.

When even rich Hollywood celebs feel they need to bribe colleges for their kids to get in, we know we have artificial scarcity and an old boys network.

Flipping the classroom is not enough. Here is what we can do to fix the educational situation: http://magarshak.com/blog/?p=158

The main goal of the people working on Urbit, as with most ventures, is to make money.

They make money by selling you an identifier that gives you access to their network for ~$10-$20. They have 2^32 identifiers so they expect to make a lot of money.

Keep in mind that this identifier doesn't mean you "own" or "control" much, as it is folded under a parent identifier of which there are only 2^8, all controlled by the original Urbit creators/their associates.

The rest is a semi-interesting mix of distributed systems + crypto ideas as other commenters have tried to summarize; there are other, less indecipherable, projects with similar ideas.
Definitely. But it's the healthy kind of pain, "ripping off the bandaid".

The problem is that universities are neither trade schools nor a place to broaden your horizons. It is a way to get a credential that you can use to signal your worth on the job market.

If testing your skills was done outside of school GRE-style, would all these people who pay many thousands of dollars to get a diploma pay so much? I really doubt it.
That sample sounds less like Yoda than it would if I taught my chihuahua to speak.

Don't mean to sound harsh, but doesn't it seem like given the title and content of the link, the audio should somewhat resemble Yoda's voice? If you played this to me blind, I probably wouldn't guess it was supposed to be Yoda in my first 3 tries...
Erlang VM is consistent/predictable in terms of latency, it's engineered that way. For pure computational performance you won't find it optimal.
This seems like mostly a problem in the US? I live in Spain and have Movistar as my ISP. I only pay for the service(600/600) and they provided me with an ONT and a router free of charge. Granted, the router is absolute garbage(WiFi is 802.11g, and I received it in 2020) but it was free. I use my own router, so doesn't matter for me anyway.
True, and indeed swapping a $2k a month rent payment for a $1k a month mortgage payment (that ends after 15 or 30 years) can make sense. But people have different tolerances for risk and to me securing multiple years of debt with the roof over my head scares the shit out of me.

I bought my house about 60% cash, 40% an unsecured personal loan I could default on without losing my house. This is only because my house was insanely cheap, though.

One thing to add is that jet engines are quite different from piston engines with propellers. So, whether you learn in a Cessna 152 and then step up to Airbus/Boeing, or learn in an electric aircraft and then step up, is probably not a dramatic difference.

> There's a reason many ancient religions forbid loaning money at interest entirely; and it's the same reason we have bankruptcy laws.

The Catholic Church condemns usury as intrinsically evil because, in the words of Aquinas, usury is to "sell what does not exist". [1]

Aquinas observed that some goods are consumed by their very use, such as food or drink. Allowing someone to use such a good is equivalent to transferring the ownership. You cannot "rent" a sandwich or allow someone to "borrow" a bottle of wine, at least not if they intend to eat or drink it. Once the ownership is transferred, you have no basis to charge for its use.

He argued that money was an example of such a good. The only way to use money is to spend it, and it is consumed by that use. Therefore, loaning money at interest is an attempt to "rent" money that you no longer own, which is unjust.

Today, there is much greater access to profitable investment opportunities. It is even possible to obtain a guaranteed rate of return on money through CDs and GICs. It is therefore licit to reflect this in the "price" of money that is lent, but this is not usury. The Church cannot change her definitive teachings of faith and morals; usury has always been and will always be a grave sin. [2]

I feel like the AI is rickrolling us, as it never quite gets to the chorus. It ends the first verse/pre-chorus at 0:30, goes into an instrumental, then repeats the pre-chorus, then babbles unintelligible until song end.

You're right that MPMC queue is a specific case of req/res where responder doesn't switch to a channel for replying so it does make sense to switch to it; nothing will be lost. You could even use the pubsub protocol by putting a query param (pubsub=true), instead of reserving a whole path prefix just for this protocol. I'd still keep pubsub because it's still useful in the general case, especially since your initial itch to scratch, poor man's notification, is done in pubsub mode

(Side question: why use pubsub for notification ? You wouldn't want to lose the notification if no one is listening on the consumer side... but you also want to possibly send it to multiple consumers at the same time. Maybe there's space for something a bit different, like "As a producer I want to block until at least one consumer is here; if there are multpile, send to all of them")

The only concern I'd have is that in the general case of req/res there's no "easy" cli tool to parse the request headers and a potentially streaming body, so it's harder to do a 1-liner (or a 5-liner) to process the input.
Sorry, I did miss that. It is unfortunate your employers are not supportive of your career ambitions. I've watched many engineers become managers at PlanGrid, so I know it is possible :)

It's not clear that this is for roughnecks, specifically. Quite a few of my old colleagues who were field engineers on oil rigs are now software programmers -- myself included. Most of us had to be above-average at windows administration just to keep our jobs and not get fired. When you're in the middle of nowhere with no ability to call/text/email and the computer on the oil rig doesn't work, it's really up to you to know how to fix the [networking]/[drivers]/[re-crimp wires].

A lot of the oil field workers hold degrees that required calculus, they should be able to transfer to entry level jobs in other knowledge-based careers quite well. Better for our economy than forcing them to be Uber drivers and bartenders. What's your suggestion for what society should do with oil workers?

I'd imagine many roughnecks would transition just fine to hands-on labor jobs like solar panel installation, wind turbine maintenance, and communication tower work. Possibly quite a few roles in datacenters as well. Several of my friends climbed towers and my cousin runs a tower modification company - the habits/skills/necessary tendencies transfer fairly well. Obviously a good degree of re-training is necessary and the workers need to understand and accept that they'll be down-leveled when they enter a new industry.
for me this is a common pattern:

ssh x

then in other windows, I do things like this:

scp file x:
ssh x command
rsync from/ x:to/
emacs /ssh:x:filename (this is tramp mode)

edit: one more thing

ssh x -o BatchMode=yes command

if you have an automatic script to run on a remote machine, adding BatchMode=yes will make it error out instead of stopping and asking for a password
I think it's more of a problem that the economy simply doesn't need as many people with college degrees as are produced. Even if companies need to filter candidates for competence, they'd still have to do that, and we'd still be stuck with a glut of people with credentials that will go unused due to over supply. I don't have an answer to that. (except that apart from the massive debt problem, I still think it's a net positive in society to have slightly better educated people even in low-skill jobs.)

As for free college, countries that have it don't just make it free for anyone: there is a significant filtering process that entails tracking students who don't perform academically into paths more suited to specific trades instead of college. If there's a solution to the above problem, it need to include something like that as well.
You're fine. The simplistic interface that Redis provides to sets, and therefore empowering pragmatic recommendation engines, is the perfect tool for this job.
> blocking outbound SSH would also mean you couldn't use Git, manage servers in the cloud or other locations, transfer files, etc.

That's right, and that's how it is with my current employer.

If you need outbound SSH to work with Git, that probaly means you're working on a side project, not work. Fetching public code needed for work from a hosting site can be done over https.

Managing servers in the cloud, ditto. If managing servers in the cloud isn't part of your job description, why would your workplace enable that?
Saying they "lost" in this context means they got to a point where it was clear capitulation to open source was the obvious play.

as a Yale alum, I like to play the drinking game "take a shot every time a Yalie uses the word 'qua'"

in all seriousness, decent take, but it doesn't seem to add that much to Andreesen's essay. e.g. the whole bit about how building a new world is inherently political... yes, in a more philosophical sense. But when Andreesen writes "we need to separate the imperative to build these things from ideology and politics. Both sides need to contribute to building," he clearly is referring to America's dysfunctional political climate, not "living together" / some conception you'd be considering in political philosophy.

fwiw, I do think Andreesen's essay could have more explicity (as Isaac's is) criticized out how creative/productive effort has been spent in recent times. I remember reading a quote about how crazy it is that the nation's (and globe's) top talent is being brought to Silicon Valley to, in large part, figure out how to more effectively addict young people to their apps (rather than, as it were, "build for good").
Originally Urbit was explicitly pitched as a political system. More recently they don't talk about politics and I don't think anyone has worked out what the emergent politics of the Urbitverse would be.
I like Cory's attitude towards this situation, he kept lean, diversified and currently he is in a good state, even though his startup Place Card Me is mainly aimed at large gatherings. Curious to hear how others are handling Corona right now.
For some reason, this article really aggravated me.

The conclusion about the pricing model feels the most forced to me. What he's really saying is that he wanted to limit the number of customers to 25 or so and achieve a $2k MRR within 2 months. The reason for this was to have more time for other pursuits, such as homeschooling the imminent child or other pursuits. Implied there is some amount of time required that is << 40 hours/week.

Reading his initial blog post, he doesn't mention the pricing model at all. He does mention taking a week to build a POC that his dad can show to his co-workers as well as contacting a few hundred BI folks via LinkedIn. That doesn't seem like a terrible approach. Build something, see what resonates, etc.

Reading the article, what really seems to have happened is that he spent a week creating a UI POC, shopped it to 30 BI folks on LinkedIn over two weeks, and didn't get traction. I'm not sure what happened to the 20-30 reach outs per day.

The real reason for the failure wasn't the pricing model, it was that the developer wanted something that would earn $2k/month with little to no effort on his part. The main reason the project failed was because he did no research in building it, and then decided not to continue it. The "pricing model" comes in when he decides what # of customers he can support in whatever amount of time he was willing the spend. He then extrapolated a number from that to get $2k MRR. Then, and only then, did he actually look at what comparable products on the market charge.

The more I think about it, I'm pretty sure the whole exercise, including the "pricing model" conclusion, was simply an exercise in content generation. If so, well played, sir.
I think lots of it is due to bad biased advice. True story, on my first day of college, at the convocation, the university president told his true story about how he decided to stay at university for an extra year "to study the classics" and what an amazing decision this was for him. He encouraged everyone to seek erudition.

I wonder how many students accepted that as fact. Because it is indeed a great strategy if you are wealthy and have a social-network safety net waiting to bail you out with a nice job after graduation. But for working class students like myself, it is horrible advice. I couldn't have graduated a moment too soon, I need to help my mom with rent, pay loans, etc.

You have wealthy "successful" academics and others giving advice that is noble but unrealistic and downright harmful in some cases.

Except there's nothing stopping you from creating your own subreddit. There's no limit to them.

In Urbit and Feudal systems, there's an idea of there being

1. A limited amount of land/resources

2. Some barrier to entry to getting them.

In Urbit, there are a set, fixed number of "galaxies" (similar to subreddits in your example) that have all already been given out. Planets themselves cost money and there's an exchange for them (https://urbit.live/)

Reddit isn't a comparison at all. There are very many examples of communities whose users got sick of the moderators of their subreddits so they split off and created a new community.

The point is to demonstrate that if a fictional character in a work of fiction does X and it works out, that does not serve as evidence that a real person doing X will work out in reality.
I personally have always found the idea that “tons of people are using it” to be a pretty unconvincing argument. Sometimes people invest huge amounts of money and time into useful things, like the internet, but people have also invested huge amounts of time and money into some really stupid bubbles too. I would 100% be comfortable saying that thousands of people and $150B are completely and utterly wrong. They might not be, but it wouldn’t be the dumbest bubble in living financial history.
Simulation games like Factorio, Rimworld, Kerbal Space Program, Dwarffortress etc use 100% of single CPU and <10% of others. In factorio, I can make ginormous factories that are bottlenecked by a single CPU. Sometimes say my factory produces X rockets per game-minute. I make a bigger factory that produces Y rockets per game-minute where Y >> X but since now CPU cannot handle the load I now produce <X rockets per real-time minute. So making my factory bigger was a net negative in terms of rocket per real-minute.
I wonder if it is illegal under GDPR to include spying apps on phones without telling the user.
>The reason they aren't dischargeable is because what bank in their right mind would give a loan to an 18 year old with no collateral?

Why is that a bad thing? This pushes choosing a good degree from something entirely on the 18 year old to something the market is deciding, by calculating the risk of a default, and removes much of the penalty from making a bad call from the 18 year old. Yes, not everyone will qualify for a loan, but if the bank who is interested in making money off loans decides your plan isn't worth a loan (and this bank has plenty of money to loan, so it can invest in many and aim at averages) thinks you are too likely to not get a good job and will default... maybe you should consider what that means.

And it puts downward pressure on college prices, like you mention.

>they would just be completely out of reach of poor and middle class students.

There aren't enough colleges to survive on just upper class students. So either the colleges will go out of business or they will have to learn how to be in reach of the rest of the population.

That's not quite the right explanation. With the pump in the loop, the heat transfer speed is actually quite high, and ideally the temperature difference between "after CPU" and "after radiator" is small. Without the pump (ie. "bowl"), the temp difference would be quite big until convection kicks in.

However, cooling on any radiator is a function of the temperature difference between air and metal. The heat from the CPU will slowly heat up the water and radiator, which has actually a large heat capacity. That takes times, so the temperatures go up slower. When the heater stops, it will take the radiator also comparatively long to get that heat out of the water again.

A normal air cooler has much smaller heat capacity, so will react much faster, in both directions. These faster cycles are certainly less good for the CPU than the slower cycles of a water loop.

Reddit doesn't make sense as a comparison because there are no limits to how many subreddits can be created, and communities split off from larger subreddits reasonably often when they don't like the rules.

In Urbit's system, you can't do that. If you don't like what the person at the top decides for your plebian self, then you're SOL.
