Mutual credit means everybody can extend credit to another peer, and there is no centralized issuance of credit. The agreements themselves are fully p2p without any 3rd party. Using mutual credit (which the Holochain pattern/framework is specifically designed to do) [1] also means the mutual credit protocol/agreement itself can evolve without being bottlenecked by the developments of said 3rd party.

"Check out, for example, mutual credit systems like Sardex, where small businesses get together to issue money as credit to each other. Everyone starts from zero in the system, and then goes into and out of short-term debt to one another by either receiving goods and services — which creates a future obligation owed — or by being prepared to offer goods and services to people on the system, which earns you positive claims on others—otherwise known as money."

> Education does not equate to a successful job

Yes it does, statistically speaking.

Career academics are a tiny minority of the population. The median salary of a BS degree in the US is 2x over non-degree holders. The median salary of an advanced degree is 3x. Twice the salary for having a 4 year degree, that is enormous.

These stats were published very recently by the St. Louis Fed: https://files.stlouisfed.org/files/htdocs/publications/revie...

Before I saw the statistics I would not have believed the difference is anywhere near as large as 2x.

This idea is so great, really like it. But I don’t know how practical it is. From the article, It improves the UI and interaction of the CLI, "That means that images, gifs, video, graphs, interactive diagrams, buttons, and forms should be able to integrate directly into the CLI experience." which may improve the user experience, But the basic mode of interaction of CLI doesn't change. The CLI experience is still not intuitive. Maybe CLI will work well for simple scenarios, but I don't know if it is a good choice for the complex circumstances. The complex interaction and graphical interface display of some industrial scenes may not be well expressed by the CLI, Even they cannot interact only through the keyboard. So I worry that CLUI will face a situation where complex circumstances are too much to handle and simple scenarios are unnecessary. Actually, there has been some CLI tool through shortcuts and custom instruction to do these things (autocomplete, fuzzy-search, tips or guidelines) with text way, They also did well.
> don't read as it's a marathon, take breaks, think about that bits you've just read that was interesting, then promptly forget about it.

That's basically the spaced repetition model. You need to forget a little bit, so that working memory isn't saving you, and the recall process takes effort. That's what builds long term memory. Spaced repetition systems just extend that process beyond the length of the book, in a time shorter than rereading a book.

> Quite frankly the idea of knowing /by heart/ the name of the greek goddess blah blah blah he uses as an example would bore me solid.

I agree, the names of greek gods is a bad example, unless you're a student of mythology. Spaced repetition is hard work, so probably only deploy it on things that matter. A better example might be Bayes Theorem. Incredibly powerful, but unintuitive and easily forgotten. Cards for Bayes' theorem might include the purpose: "Bayes' Theorem calculates how to adjust our prior beliefs given new evidence", as well as cards about the formula, or an intuitive visualization.

Or, maybe you want to learn more about the linux internals and spend a portion of your time memorizing the meanings of signals and errnos as a small part of a larger program of study. Sure, you can look these up in a man page, but part of the value in knowledge is knowing things exist. How many developers do you think know of SIGUSR2? Or... SIGBUS ;)
You people are smart here. Should I be worried?
You wrote that the median American worker can’t take time off to campaign. That’s correct, they can’t.

The point is that lots of people, of all ages, both young and old, who’s net worth is significantly above the median, can afford to take time off to campaign.

So, yes, people with a higher net worth are at an advantage when running for president, but this doesn’t really explain a bias against younger presidents, since there are plenty of wealthy younger people, in terms of sheer numbers, just not in terms of percentage of the population.

Also, you wrote that people over 55 represent 1/3 of the American population but own 2/3 of the wealth. This can at least partly be explained by the fact that most people’s net worth increases with age and not just linearly. Plus older people often inherit some wealth from parents who die, increasing again their net worth.

If the same pattern stays in place for future generations, if they also get wealthier with age, I don’t personally see that as a big problem. Do you?

If on the other hand the pattern doesn’t continue, and younger people don’t get wealthier with age, then, yes, I agree that’s a problem.

So Facebook is suing to dispute the business model of whoisguard, because they believe they are "obligated" to work with fb? I'm scratching my head at the implications here, I can guarantee fb doesn't want to be responsible for kyc on their users or ad providers (both can deliver intentionally misleading content on their platform). So what is their goal? My best guess is they think they can scare namecheap into working with them, but this feels like a case of chicken.

I'm arguing that providing a solid safety net doesn't seem to drive that much entrepreneurship.

Canada is a great example. People are very risk adverse, don't start many companies, but have a solid safety net they could rely on.

And Canada is #3 on that list and as a Canadian, I can say that entrepreneurship here is a fraction of what it is in the US.

There are some research showing that it helps. Other than the one linked in this post, here's a couple others:

> Among nurses in Ontario tertiary care hospitals, use of a surgical mask compared with an N95 respirator resulted in noninferior rates of laboratory-confirmed influenza.
https://www.ncbi.nlm.nih.gov/pubmed/19797474

> during a severe pandemic when use of face masks might be greater, pandemic transmission in households could be reduced.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2662657/

Also, purely anecdotally, in Hong Kong and Taiwan, virtually everyone are wearing masks when going out in public. Compared to other regions, the spread is much more limited despite the close proximity to China - Taiwan had blocked entry from China early on, but not Hong Kong.

Lastly, even if it "only prevent the sick from spreading it", wouldn't it help with limiting the chance of the asymptomatic cases from from further spreading the disease?

Now, if the general population purchasing masks is truly impacting the medical staff's supplies, then it's a legitimate reason to ask people to stop buying them. But telling them it is useless seems quite misleading.
An excellent example of a well meaning regulation with weird real world consequences.

The new EU directive to hit 95g CO2/km is a much better regulation since it directly measures the goal: less carbon emitted. It also measures the fleet more directly, unlike CAFE that carves out tons of categories. It does allow for the double counting of EVs for a few years which incentivizes doing the R&D on EVs rather than paying penalties.

> As with all currently available tests, it’s not yet clear how long a person needs to be infected before testing positive, or whether they could be identified by the test before displaying symptoms.

Kind of made me sad. We're celebrating that we are able to test something, in very... precarious? .... results. Of course it's amazing that we're able to known the genetic sequence in so few days. But as travels are much faster around the globe, it takes so few days to spread. Everything being so fast isn't exactly helpful to settle emotions.
> Because UBI is a misguided effort. It aims to fix inequality

No, it's a tool among many that can be used to fight inequality, not a solution in itself, despite attempts to depicted otherwise by both its supporters and detractors.

> More sustainable solutions would arguably revolve around improving the educational system and revisiting {fiscal, educational, cultural, ...} incentives

This reads like a thinly veiled recommendation to privatize schooling, reduce government supports to make people"hungrier" for success, and leave people's welfare to the conditioned charity of narrow cultural interest groups. Let the "best" rise to the top in the arena of struggle.

Dr King had the best summary of this: socialism for the rich, rugged individualism for the poor.

Incentives working ways that can drag society backwards also. Set up the system so the masses struggle to keep their heads above water, and what you'll likely end up with is a lot of destructive behavior whose cost is borne by society at large.
Show HN: Managing Kubernetes Workloads over Unstable Network
Now Kubernetes has become the de facto standard for orchestrating containerized workloads running in the data center, and rely on the stable network of the data center.

But in scenarios such as smart park management or CDN，we will run the master in the data center, and the edge nodes in various decentralized areas. At this time, there is no stable network connection between K8s master and edge node, and the node may even be offline for a long time. This indeed caused troubles: the control events from the master to the edge nodes may be lost, which cause troubles for the edge applications management.

It depends on your data ingestion semantics.

In a data-warehouse built up from event-sourced data, "missing" and "unknown" are the same thing: "I don't have this in here yet, so once I get it, it might turn out to be anything."

For a column with a value you know is "nothing", I'd suggest you keep a separate column to denote the type of the column, just as you would in a union data structure. After all, the explicit choice to have or not have a value is, itself, data, that you can either be in possession of, or not. You can't use one sentinel value to indicate both "absence of value" and "absence of knowledge of absence-state of value"; you need two! (Of course, if your knowledge of the absence-state is absent, the data is probably absent too, so you'd probably have a CHECK constraint to assert that if the tag is NULL, the data must also be NULL.)
I'm pretty sure there'd be a huge difference between doing this with old TV shows (familiar, no learning, basically structured background noise) and doing it with podcasts (new material, news, etc).
Totally agree that the nice thing is everything stays in one place. I use it for Stack Overflow as well. :) And will definitely add Reddit to my list.
I worked for a European domain registrar a few years ago.

An obviously malicious site like "whatsappdownload.site" would be taken offline very quickly, but under no circumstances could we give non-public subscriber information to a third party without a warrant.

> You're glad Namecheap is protecting the registrant of "whatsappdownload.site"?

In most cases I've seen, registrant data would either be fake, the result of identity theft, or an innocent customer's whose account got hacked.
I think normally they would sue the people who registered the domain to get a subpoena, not namecheap itself.
This makes it completely pointless to even have a high-dpi screen. I think it is a pretty common use-case to have a new 4K monitor together with older FHD ones, or a high-dpi laptop with a low-dpi external screen. X really shows its age in relying on everything having roughly the same pixel density.
If I read the claims correctly, it takes an unlabeled dataset + a classifier model + a handful of heuristic labeling functions, which may be both partial and inaccurate, and trains the model to be a good classifier for the dataset, without ever requiring per-example manual labeling.

Quite magic.

Your best bet is to cut a piece of paint off the wall and take it to a paint store. They probably won’t be able to match it exactly, but it’ll be closer than you can do in RGB.
Knowing 1% of reported cases are asymptomatic doesn’t tell us anything about what percent of asymptomatic cases are unreported. Only way to know what is testing with random sampling from the asymptomatic general population.

Well, the original one isn't unordered, and isn't meant fundamentally to be "searchable" (its original "implementation" being index cards).

Here's my attempt at conciseness:
A zettelkasten is like a bunch of files in a single folder with
1. a naming schema that kinda indicates what follows what (an ordering scheme, but persnickety and optional, see https://zettelkasten.de/posts/luhmann-folgezettel-truth/), and
2. links in between the files, originally just by writing the names to be manually looked for.

Some people use 2 to be able to get rid of 1, as with an indication of PREVIOUS (link) and NEXT (link)

The point is that you have one thing on each card / file that you might want to go back to on its own.

It makes a lot of sense in academia where you want to be able to trace ideas in a referenceable way, identify your own takes on bits of other people's work, and connect different sources together when you see similarities.
When's the last time that someone tested a series of satellites (or launch vehicles), with a number of up-front failures? Prior to SpaceX, of course. To me it looks like that sort of iterative trial-and-error design process died with the end of the space race.

For instance, looking at LandSpace - that quote relates to the launch of Zhuque-1, of which there has never been a repeat despite a maiden flight in 2018, and Wikipedia says that a second flight ever happening is doubtful. The company's second launch (and probably any after that, too) will likely be with a completely different, liquid-fuelled design.

THAT's what failure normally looks like in aerospace. Whoops, we fucked up, and so now that design never flies again, or the company goes bankrupt, or everyone panics and goes through a massive design review because everything was supposed to be perfect and now obviously it wasn't.

Education signals that you are "better" than those with worse education. Smarter, harder working, etc.

We need to create better options for students. We can do this by refocusing education on learning practical skills for real world jobs rather than maintaining an educational system built upon a foundation over 1000 years old that up until 100 or so years ago was intended for the elites and scholars, not the average person looking for a job.

It all comes down to the false negative rates though.

This isn't a court, you don't have to litigate this detail.

Oh, but it's "wrong." Let us now break out the XKCD.
Aside from the fact that HK has much fewer cases than a lot of places despite the close proximity to China. For the past few weeks, almost all new cases were traced back to either people sharing meals with someone who was infected, being in the same unit of someone infected - both of which situation would involve removing the masks.
I thought so too, at first, but the new information is not just that some Crypto AG products were somehow compromised for some customers (widely reported since the 1990s), but that the company was literally owned by the BND and CIA. Not in a metaphorical sense of owned.
Nice to know the site. I found Hootsuite is also a nice place to manage a Twitter handle.
I used to work for a company whose licensing fees were mid-five figures a seat. Granted, not every person in the company needed a license; but nearly everyone involved in the production process did. The company also benefited from vendor lock-in, because skilled workers tend to get pretty attached to their workflows and competitors in niche software tend not to have 1-to-1 feature overlaps.

It seems like nearly every profession has high-priced software that's required: artists, engineers, accountants, lawyers, doctors/nurses, research scientists, architects, etc, are buying products from Adobe, Quicken, West Law, Reed Elsevier, Epic. None of those are small companies, yet all of them focus in somewhat niche information technology sectors. I'm struggling to come up with a profession that doesn't touch software anymore; even retail workers use point of sale and inventory software.

I do agree with your sentiment though. The software is expensive because it's so niche. The market for all of this stuff is pretty limited, meaning there's only a few products offered, and the capital required to build competitive products makes it prohibitive for a company to build their own. The companies making the software also understand their target industries intimately enough to know exactly what price the market will bare.

However, it does leave an interesting market opportunity for and engineer + domain expert to tap into the market with cheap, low-feature offerings. Or maybe we will see more companies bringing development back in-house.
