Yes, about 1700 per second. Which is about the average number of Visa transactions when averaged over a whole year but still very small compared to what VisaNet is capable of (about 65,000 transactions per second)

I can’t find examples of number of cash transactions per second globally, but the Eurozone averages 1.2 cash transactions per person per day (and 0.3 card txs/person/day). Give that there are 7.8 billion people in the world, if each makes on average 1.2 cash transactions per day and 0.3 card transactions per day, that’s about 100,000 cash transactions per second and 25,000 card transactions per second.

Cash, of course, is trivially scalable. At current usage rates, VisaNet could handle all card transactions if everyone used cards as much as Europe. Total payments of about 125,000 per second is about 2 orders of magnitude greater than what a Bitcoin with 1000 fold increase in block size could do.

None of these systems is setup for micropayments. And increasing the Blocksize doesn’t change that. Visa or cash still seem far better for the small, casual payments Satoshi imagined Bitcoin would enable.
When Apple ran diagnostics, did they also say nothing was wrong?

It's completely possible to have dud hardware that is not caught by software. I'm about to send an old MBP to get its battery replaced because it's bulging, yet the battery health tool says it's fine.

As far as your m1, something is definitely wrong. It's not just benchmarks have shown that it's fast, but in day to day usage of many common programs. Your m1 experience is the exception, which likely means a problem with your machine.

Indeed, however I feel when you immerse into local culture, eventually we find out there is a thin common culture across the continent, regarding what everyone was watching while growing up or certain points of view versus other continents.
I don't think there is a stable "vertical" configuration without the negative mass trick from crossing lines: https://en.wikipedia.org/wiki/Metacentric_height

Any convex shape will tend to minimize the forces due to buoyancy and "horizontal" should always go less deep (or equal for a sphere) than "vertical"
I don't understand why "instant on" after sleep is supposed to be new when my white iBook G3 already had that back in 2002.

The article has a section that addresses this.
Anecdota:

Mixed-age groups of home-schooled kids (e.g., at co-op events) tend to just play, with the older ones typically watching out for the younger kids, whether they are siblings or not.

Mixed-age groups of formally-schooled kids begin by setting up a hierarchy that usually depends on grade in school* and then is continually refined.

* H-S kids in a mixed group are immediately marked as outsiders by this question. They either don't know or operate at different levels in different subjects.

That indeed makes sense, but sometimes one hand doesn't know what the other does. Also not all decisions are rational (actually it's the other way around). A better example for this is the FBI tho, since they really hate any security mechanism that plebs can use.

I'm not saying that the NSA has any involvement in this situation, but clearly their strategy is sometimes to undermine security. It's not their whole schtick, because of NOBUS, but still part of it.
Please continue hacking on X if that's your fancy, I agree that the codebase is fine as far as legacy codebases go, the real problem is that the protocol itself has issues and that can't really be changed without breaking backwards compatibility or breaking ABI in xlib. Adding yet another security policy to the X server might fix some issues people have, it unfortunately won't fix all the other problems.

No, with this law Facebook is not free to not buy the content. They are specifically forbidden from excluding those media companies from results, and lets not forget the cherry on top of the shit sandwich which is being forced to share their algorithm with the media companies, and even having to give advance notice of changes to their algorithm, something which is probably not even possible.

On top of all this, the definition of "core news" in the bill is ridiculously broad.

It's completely untenable, and IMO Facebook would surely (and predictably) have to leave the Australian market under those conditions.
The funding angle aside, there are still reasons why large airports have their own "terrible trains" (and buses) to connect to the transit system. There's usually just one airport stop in any case, which in a major airport, may (or may not) be convenient to one or two terminals but will require some sort of separate transportation system from at least part of the airport.
I'd say that of course you would be willing to ignore that data, since it explicitly runs counter to a few of your viewpoints... Those points you're making would anecdotally influence the global tendency that shows violent crime (the one that makes you take your kids off the streets, not illegal downloading, mind you!) peaked in the 90s, from very low (aggregated) levels throughout the century.

I've been solo running/building a startup (csper.io) for over the last year, it just hit profitability a few months ago.

It's easier said than done, but if you can prevent issues in the first place, things will be much more enjoyable.

Some things that worked well for me:

* GKE on GCP is pretty smooth. When there's a spike in traffic everything autoscales up, so I don't have to do anything. Nice observability, things just work. Just make sure to set container cpu/mem limits.
* Along that same note, I use MongoDB Atlas which also autoscales very nicely. It autoscales both up and down very well, saving both money, and making my infra resilient
* GCP has a lot of monitoring/alerting/dashboards that I take advantage of. Health checks around the world, easy integration of logs/metrics. I find structured logging (json), makes setting up alerts pretty easy
* Good consolidated logging for when there is an issue you know exactly what went wrong
* GCP also support application tracing which can make timing issues easy to debug (although it requires a bit of work to setup) (for example if you are missing an index on some db)
* Automatic deployments (thanks to k8s), there's no checklist for doing a deploy, I just run a single make command. I can't screw that up
* A staging environment that's a match of production. Plenty of times I've crashed staging, it's worth every penny. It also makes life much less stressful
* Lots of tests. The tests aren't important for when I'm writing the code, but for months later when I make changes and want to know I didn't mess something else up. I find a good test suite can really help you sleep at night, specially if the test suite covers the critical paths
* An easy way for users to contact you if there is an issue. No one is perfect, but being able to respond quickly is usually forgiven.

Also "stay-cations" are also pretty nice. I try to do one a quarter. I'm still at home if something does break, but I don't do any work for the week. Just load up a new video game and relax for a week. I call it my "monitoring" week.

Hope that helps!
If you're doing things purely from the ego, then expect things to get complex and feel tedious. Part of being able to hack your flow state is to get inspired early and often. The word inspire is derived from spirit so you need to think of your tasks as a spiritual act.
This is a false dichotomy. You can be critical and do so respectfully and within the company.

I think you’re misunderstanding how essential and varied proteins are. In simple terms they are the nano machines which actively do stuff in cells. https://basicbiology.net/biology-101/molecules-of-life

Essentially, DNA encodes Proteins which manipulate everything else. Human cells for example have on the order of 1 to 3 billion proteins, remove water and over half of what’s left is proteins. https://en.wikipedia.org/wiki/Protein

The online arguments I get involved in are resolved often. Because I try to have them resolve. Plenty of times it's totally easy to resolve an argument. It can go like this: you spend some time thinking, realise that the person you're arguing with is correct, then you say "Oh, I see your point now. I didn't realise x which is what lead me to think y. Thanks for helping me realise this mistake and gain a better understanding of the issue."
I think there’s too much corporate dependence on Linux for it to go away. There may be a tragedy of the commons where companies dependent on Linux fail to invest enough in it to keep it thriving. And corporate purposes may not align with hobbyist purposes, but I think Linux will persist as more than a zombie.

I’m somewhat more worried about the maintainability and churn of the ecosystem built up around Linux. The video mentioned OpenBSD a couple of times. OpenBSD shoulders a disproportionate share of the burden in maintaining important infrastructure. Take a look at all the spinoff projects OpenBSD is responsible for, feel queasy, and then write them a check. They make a pretty great OS too ;-)

Many USB 3 devices cause interference in the same frequency bands that Bluetooth and Wifi also use.

USB 2 has lower bitrates so the interference is in a different band.
I don't understand this comment. All modern filesystems are extent-based. If you have enough contiguous space, a hundred gigabyte file could easily be stored in a single extent. Block-based allocation hasn't been used since ext2/fat32. Could you elaborate?

I say this as someone who was a nerd in the '70s, before it was cool, but the problem is, we have a bunch of children that needs to be taught many subjects to be productive citizens, at a level of expertise not seen in history. Their parents go to jobs during the day. What is a better solution than what we do right now? It's certainly not perfect but what can we do better?
In the past we had apprentice programs but youth learned one trade, little history, math, "social studies", other things we expect people to know.
We are trying an experiment right now due to the pandemic - remote learning. It exposes a digital divide for sure, but we can all see where that would be less of an issue in the future. It's being called a failure by parents, kids are falling behind, mental health issues are climbing. Kids, people in general, need some kind of social interaction for their health. So, back to school? Back to my original question? What can be better than what we do now?
Vista was still a loading bar style boot more similar to XP, flying colors to form the pulsing logo was Windows 7.
The page also talks about a variant, countercurrent multiplication. There's a really nice example of this in hydrogen isotope separation. The technique, called CECE (Combined Electrolysis Catalytic Exchange), was developed in Canada for production of heavy water and removal of tritium from heavy water.

The centerpiece of the system is a catalytic exchange column. In the column, liquid water flows down, while hydrogen gas (of various isotopes) flows up. At each point, a wet-proofed catalyst promotes the exchange of hydrogen atoms between the water and the gas. In equilibrium, protium partitions more into the gas phase than into the liquid, so as the gas goes up the tower the heavier isotopes are stripped into the liquid phase and carried back down. At the bottom, the water is fed into electrolysis cells to produce gas to feed back into the tower. Over time, the water in the cells becomes enriched in heavier isotopes and can be tapped off.

With this system, any H2 electrolysis plant could modified to also produce heavy water. This has troubling implications for nuclear proliferation in the coming "hydrogen economy", as heavy water reactors can be small and easy to hide, and have been used in the past for nations to enter the "Nuclear Club".

And yet, when I had to return my M1 Macbook Pro 3 weeks back because of dead pixels, the dude at Best Buy told me that in order to wipe it, they had to update the OS because the version of the OS that came installed had a bug that would make the machine unbootable if they tried to do a factory reset from that version. So it had to download ~3gb to update the OS, just to wipe itself.

That's just bonkers.
If everyone uses a tool wrong, it's not a problem with the people, it's a problem with the tool.

Jira makes a lot of bad design decisions. Virtually everything it does has no undo. Different issue types behave almost, but not quite, the same, and have far too many different fields that end up meaning almost but not quite the same thing, so denormalisation and inconsistency are rampant. It's a micromanagement-first system: everything you want to do has to be explicitly enabled by a manager, and if you want to do something a manager didn't think of, too bad. And its performance is awful.
Large airports outside the US often do have one station per terminal, or a station conveniently between two terminals. See eg London Heathrow, Tokyo Haneda, Tokyo Narita, Kuala Lumpur, Delhi and many more.
I take a more optimistic view. Digital currencies seem to be perfectly suited to transactions where corruption is rampant. Take the construction industry. There is poor chain-of-custody and a lot of counterparty trust involved, so things disappear and the mafia gets richer. I don't want the construction industry to have great privacy standards, I want it to be transparent. So digital currency can absolutely be bad for privacy and a boon in certain spaces, specifically ones where trust is commonly abused.

Cash can still exist in industries where we want trust to exist between different parties, those kinds of spaces are small enough that I doubt they'd be worth the effort to eradicate anyway.

Not to say that I like where all of this is going myself, but blockchain for large and official transactions + metal currency for local informal transactions is one direction I wouldn't mind at all.

I agree that short term thinking is a huge problem. Almost all the reps/senators are optimizing for winning the next election 2/6 years away. It's just a sad state of affairs. I have no idea what the problem to the soliton is. But unless we do something concrete, seems like things will get worse as weather patterns keep changing.

Expectation management. There's such rancour about basic questions of what people in society owe one another than it can't be any other way. The rancour is stoked by people who have the most to lose from a redistributive and rights based model of society. There used to be organised resistance to them, but it was comprehensively broken in the late 20th century and has yet to return.
Good lord the prose is gawd awful. Almost parody levels of tediousness.

The reverse is also true. People think if they experience a bug, then everyone experiences the bug and it's the most important bug ever.

Everyones setup and use case is unique. All the many interactions can lead to fairly unique bugs. Even if two people think they see the same bug, it could be two different bugs causing the same symptom.

Let's take the bugs around re-installing that have been popping up on HN lately. How many people buy a brand new machine and the first thing they do is wipe it and re-install? I don't personally know anyone who does that, it's certainly not something I've ever done with any of my Macs over the last 20 or so odd years. So while I think bugs around re-installing are important and need to get fixed, they are not something that a majority of users will run into this early in the m1's life.

It looks more and more to me like there are those who prefer the petty in-fighting to the kind of societal upheaval that could result if the U.S. enacted the kind of changes that improved life for the "masses".

It does not. You just get an email that your account has expired with a link to renew.
While the proximal reasons may be technical, the systemic cause is our dual focuses on meeting demand no matter what and growth but not focusing on resilience. The result is that when demand is always met, we grow (population and consumption) until we hit problems like this. Then we build more capacity.

It costs a lot to go from 99.99% uptime to 99.999%, but we do it every time.

The savings to go from 99.99% uptime to 99.9% is also huge. Most of the world does fine with under 99% and we could too if we built our systems and lives to handle power going down sometimes, even unpredictably. Hospitals, elderly, etc would need special treatment. The rest of us could reduce our needs and learn from how people lived all the time for hundreds of thousands of years.

We'd save tons of money, live healthier, and pollute a lot less. We'd learn to treat nature with a bit more humility and respect.
