(Author) I make my meals when I work from home, but I didn't often have time to make meals and get to campus at time, so I'd buy a sandwich or salad at the deli instead. That's between $10-$15 depending on which cafe my class is nearest. Also being pregnant, my appetite and nausea are unpredictable, so I might buy another snack during the day.

Certainly with better planning, I could have reduced those costs slightly.

Huh? So you think the problem of being behind is overstated, but observed many students not being properly prepared yourself when you taught?
On the topic of hidden gems. The info directory is frequently populated by default with manuals when you install a piece of software. These tend to be more in-depth and complete manuals then the man pages for the same tool. Just type `info` in a terminal and be amazed. Emacs has a convenient info viewer also, under `C-h i`.
I think school is more about protecting parents working capacity from their children than protecing children from the world.

Children compulsively and under duress are exposed to so many horrible people and behaviors at school that the rest of the world seems mostly like sheltered, peaceful place by comparison.

>"The idea behind web3 is that everything lives "on chain" (the same way the idea of the Internet to some was that everything is "online")."

That's interesting. For some reason I had imagined the umbrella of web 3 tech and protocols were somehow additive to what we have now. In looking at the Web3 Foundation's page I can see they have an entire stack defined but nowhere was I able to find where their "vision" for the web was laid out.[2] This seems kind of odd. Is this intentional or is this just not the right place to look?

Note that `Promise.all` will reject immediately the moment any of it's promises reject. That means the other promises will also fail.

You'll often want that behavior – just learned a new one this month, though: if you want to do concurrent promises that should be able to succeed/fail independently, use `Promise.allSettled`: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...
Back buttons in web apps are hard regardless of SPA or MPA.
I've seen many MPAs fail, for example after checkouts or form submissions.
The problem is just more prominent with SPAs because they usually feature more complicated navigation.

Perhaps for privacy reasons, you don't get much control over the built in history: you can push, replace and pop.
Maybe you could implement your own history, but then you need to somehow keep that in sync with the browser.

If someone knows a good approach, I'd be interested.

Race cars are built differently; they have a tube frame to protect against high speed roll overs and have no airbags. You wear a helmet to protect yourself from hitting your head against the metal roll cage or steering wheel (because no airbag).
Evolution doesn't suggest everyone reproduces or "stays around long enough to make sure your children have children" . In World War 2 for example lots of 18 year old men for example were drafted and sacrificed their lives without having a chance to reproduce. Taking your thought experiment to it's conclusion you might conclude world War 2 couldn't have happened.

Your argument about selective pressure would by the same logic lead one to conclude chaste nuns can't exist and monestaries and vows of celebacy are fiction.

Religious belief just needs to be useful on average for there to be selective pressure.

Also evolutionary psychologists can't really explain the existence of gay people (attempts to do so have been a stretch, according to the evolutionary psychiatrist author of The Moral Animal) which demonstrates the limits of declaring things are impossible due to thought experiments about evolutionary pressure.

That's a fine question too and I would argue that it doesn't help the real world economy. It just consumes energy for 0 utility except to facilitate ponzi schemes and money laundering

For general purpose compute relying more on ILP than DLP, I would think the range is going to be narrower. Narrow enough to be a meaningful choice for consumers using battery powered devices and wanting more efficient or higher performance laptops and desktops. For servers, it seems like Intel and AMD are choosing optimizing more for perf/$ over perf/watt in their roadmaps. HPC roadmaps might be different still.
Who cares?

The point is that now that you have a goal, you can search and evaluate sources against it. You can also rule out sources that would not meet your goal. For example you can determine that Fox News or CNN is probably a terrible source for you to try to achieve this goal

Stay away from always-online cultures like Twitter or Facebook, click-bait warrens like most "blog-news" sites, and try to read a few economic or historical non-fiction books a few times a year and you're good to go.
Most of the facts get forgotten, though I can conjure up quite a few on any class I think of having taken. The important part of education is not the facts, it is the skills. School taught me to think scientifically and critically, to write and to speak, as well as made me confident interacting in the society I live. Those skills have served me well.

It just sounds like you did not do much research. Answers to all of your questions are neither complex nor hard to find.

> will there be servers?

Yes, both practically and conceptually. Practically, there are servers acting as network nodes. Conceptually, your code runs on VMs like the EVM, which can be thought of as a distributed server.

> How do you host databases without servers?

By adding transactions to the immutable ledger, in an append-only fashion. To index the data, you could use your own node, or defer to something like The Graph.

> Who pays for hard drives for sites like youtube?

There are different models for that. Essentially the uploader, the downloader, or both.

Take Arweave, for example. There you get indefinite storage for a one-time fixed fee. This is based on the extremely conservative assumption that storage prices will decrease by 0.5% pa on average. Over the last 50 years, it was something like 30% pa.

A debugger isn't necessarily available in all environments. At my employer data scientists do a significant amount of their work in Databricks, where as far as I know it's impossible to drop into a debugger to trace execution.

That said, I'm not really defending these specific decorators.
It needs explicit conspiring to be a conspiracy. Editors could just choose not to piss them off without Microsoft doing anything.
The companies are all doing a land grab because they think if they can get the whole pie it’ll be worth quite a bit.

> It’s funny you mention browsers because there are a ton of sites and features that only work on chrome and not safari.

Is that because Safari doesn't implement everything decided by the standards bodies or because Chrome deploys their own features? Probably a mix of both, but eventually there is a convergence.

Things work surprisingly well in modern times. I'm not sure when you started using the web, but back in the 90s/early 00s, the situation was a lot worse then it was today, and the browser standards are probably the biggest collaborative achievement between corporate entities in the modern web-driven world.

> Not sure that’s the model to follow. Fundamentally though chat is different - where would the messages be stored for example? Who will guarantee deliver ability?

It might seem fundamentally different on the surface, but I think not. Just like the browsers doesn't handle where the resources it loads are coming from, messaging services can be the same way. Think IRC, or even your own example, email. As long as there is a user-agent where services look consistent, the situation would be drastically improved.

> Email is federated and has all of these things but sucks and so everyone made their own thing. I’ve yet to see evidence this just wouldn’t regress to email again

Email is another great example of a success when it comes to this. Yes, email has it's warts, but you can essentially sign up for any provider, or even create your own, and receive/send emails to any of the others ones.

I don't see "email" as a regression compared the IM situation we have today. Imagine you would need a gmail account to send emails to gmail users, yahoo account to send emails to yahoo users. That would be awful! But you're right that email could be a lot better, but still, I prefer it to the alternatives from the IM world.

A large format laser printer is horribly expensive. And most of them are only black and white. It's quite hard to make what the industry calls "large format" in a toner-based printer machine. Just getting a belt that wide, or rollers that wide, or a fuser to heat evenly that wide, is going to be super hard and hence super expensive.

But it sounds like he doesn't actually want what's called "large format" in the industry, he just wants an A3/tabloid size printer that doesn't suck. A3/tabloid is not "large format" in the printing industry. Large format means like A1 or A0 sized paper, usually on a roll.

Probably the best way to get a cost effective high quality A3/tabloid size printer is going to be to buy a used commercial machine that's roughly 10-15 years old. You'll still be able to get parts and toner for it, these things normally last a few decades. But it won't be small and it won't be electrically efficient.
Yes, there was that, too. Now I did not mean that the license is of crucial importance to most end users (it might be for some, but likely the other way around as some will prefer the simpler BSD clauses). But it was decidedly important for the business and consulting side to form, and that was hugely where Linux won.

Red Hat, Cygnus and the IBM service group took early big bets on Linux, which could not have happened on a product where vendors based their respective offerings on proprietary lock-ins. That drove adoption in banking and defense whose existing UNIX stacks looked increasingly old, which drove a huge industry shift that took the better part of a decade.

It used to be quite common to find people arguing that BSD was the more "business friendly" license, which is may be true in some specific ways but tends to miss the bigger picture. The adoption of a mainstream system under GPL license was important.

Then the situation was probably different in the web hosting business, in academia, and in other sectors where other factors dominate.
I previously used Dokku and I loved how the HTTP proxy was "automatic". I've moved past Dokku but don't want the complexity of k8s for a home network. I sort of envisioned a system that could read out running container names and create "$name.$domain" proxy entries automatically.

I never got around to it and my current method of automatically generating nginx.conf from a JSON file has a few tricks left, I guess. I guess one additional problem is that I have few things stacked up on a domain and under different "location" entries.
I don't know, I'm just saying these policies were motivated directly, maybe exclusively by racial animus.

You just proved that it's low quality as well as irrational.

On a complex topic with an enormous scope, you claim to have an absolute and extreme answer, and present it as factual. That's pretty much impossible on any topic of high complexity.

You present zero evidence to justify such extreme conclusion. That's low quality and irrational.

To come to a high confidence conclusion on the whole of web3, one would have to actually read hundreds of articles at least, and spent significant time actually using the many products. I would doubt that you did so, and couldn't even pass the most basic test.

So you have zero evidence and presumably zero knowledge or experience. And you're the rational one?
Handy but `dd` is much better at giving you a limited context to look at -
`dd bs=1 skip=236162504 count=20' just gives you 8 before and 12 after.

(edit: I do have to concede that the `tail|head` version is much faster than the `dd` - ~11s vs ~65s in my quick test with that ^skip)
Yeah but I mean: you can't really say that your homegrown Perl script running on a potato can handle 10k req/s if you put caching in front of it. What you're really saying in that case is that your caching solution can handle 10k req/s, which is fine, but besides the point.

Same with Wordpress. Wordpress itself cannot handle that amount of load, which is why you put caching in front of it. Users won't care, I give you that. But if you're talking about how much load a specific software can manage, including putting caching in front of it kind of defeats the point of the conversation.
The most interesting part is reading comments in HN. Obviously the interest of the average HN reader is different from the one from a developing country. And yet again different from our influencers (aka politicians) dictating policy - who have obviously a very biased interest in tradfi.
This is circular reasoning. It's also wrong as a general claim. Personal income, at least as traditionally measured, fell for a large number of US workers over a 35+ year period during which inflation was non-zero and yet there was not a recession covering the entire period.

There's a typo: it should have said "a lot of students". Not sure whether that was the confusion here.
Yeah, I knew about that. I had to look up their relative size to mutual funds though. Turns out mutual funds manage $23.9T compared to $5.4T in ETFs. I guess passive funds are more likely to be ETFs. But it could mean there is enough passive mutual fund money to pose a problem.

The in-depth technical article linked from TFA is worth a read[0]. It's amazing to me is that a 20 year-old sewing machine needs to be reverse-engineered and requires other hardware to make it useful. The oldest of my sewing machines is closing in on 100 years old and anyone who understands how a straight-stitch machine works could have it running in 5 minutes.

Does it embroider? No. Hell, it doesn't stitch in reverse, never mind zigzag or sew any fancy stitches (which are all combinations of zigzag and reverse). Nonetheless, it remains a useful machine. For those who aren't aware: fancy stitches can be (and were) implemented purely mechanically for decades, mostly after WWII for consumer machines. My machine is just too old.

I realize that the point of the machine in TFA is to introduce a new group of people to sewing. It seems that doing so by creating something so lacking in long-term maintainability is unfortunate.
