FCEV cars (not trucks) are prototypes pretty much. There are way too many problems to solve before they become an actual solution to anything.

A station that can fuel 2 FCEVs every 15-20 minutes costs around $2 million.

The cost of driving with hydrogen is completely bonkers compared to any other power source currently in use (natural gas, electricity, gasoline, diesel).

For long-haul trucks, ships etc. hydrogen might be a good solution.

Currently the best thing we can use hydrogen for is as a battery for renewables. Use excess energy to generate hydrogen and store it on-site. When production dips, convert the hydrogen to electricity on-site and feed it back to the grid.
> What if abandoning entire cartons of merchandise, and then shipping replacements, just has plain-old higher ROI for Amazon

Maybe it does, but isn't this because of a _negative externality_, i.e. the "indirect cost to individuals" (1) who deal one way or another with the pile of abandoned packages?

So Amazon is like an river polluter in that regard, dumping the problem because it's cheaper _for them_. It should be clear that this is not a net good thing.

There has been a number of submission on HN discussing the chip shortage - and I’ve yet to see anyone discussing using second hand chips, scavenging from used electronics. Obviously as described in the post: redesign is always going to be expensive and cause delays if even possible. But I’m still curious as to why this would not be possible or at least create a much bigger immediate market for old chips?
What's rust support for structured concurrency ?

C++ appears to be going to use it as its "main"/"most fundamental" asynchronous algorithms model: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p230...

Seems quite a bit more flexible at least than Rust futures, but I am not sure I understand how they exactly differ.

More importantly than your source files, put your testing data on such a path as well. Nobody uses absolute paths in testing so it doesn't matter how many spaces your absolute path has if your input is "./tests/file1". Put those files in a folder with spaces too and throw in a unicode character for good measure.
You can avoid typing errors in commands or code as part of Markdown files (or any other markup language) by using some form of 'literate programming' like Jupyter notebooks. The default IPython kernel supports shell by putting a '!' before each line of shell commands.

Or you can use Org-Mode (with babel), if you're an Emacs user.

FTA: “Secondly, the Faculty Board states that it is necessary to improve the evaluation procedure and that digital evaluations will be used in future.”

If I read it correctly, that was autumn 2019. There must have been such evaluations since then. I think it would be illuminating to see what they said.
It seems like the period when this idea hit its peak was in the late 1980s and early 1990s. That's when there were a lot of apps built to maximize what non-programmers could do, and which also offered the easiest possible on-ramp for people who did want to write simple scripts. Among the big successes of that time:

Hypercard

Macromedia Director, which later evolved into Flash

VisualBasic, which had fantastic WYSIWYG tools for interfaces

A little later:

Dreamweaver

PageMill

All the early Web tools (there were hundreds)

It is difficult to now remember the cult that existed around Hypercard for awhile, and which lead to spin off products, like SuperCard.

There was a real mania at that time to make it easy for everyone to learn the basics of programming.

At some point after 2000, and especially after 2010, the idea seemed to fade, and the tech industry for awhile got caught up in going in a very different direction: big frameworks, increasingly complex, increasingly abstract, a development system that required more and more tools.

I would like to see some of the old "education for the masses" energy come back.
"The model was grounded worldwide but has returned to service this year, with airlines including Ryanair taking deliveries of the aircraft."

Umm, remind me not to fly Ryanair. Even if it is safe now, it just is scary to even think that I am in the air on a model that has crashed twice within months killing 100s of people each time. Does anyone know which other airlines are flying this model ?

Also, "It paves the way for families of all victims of the crash, from 35 countries, to seek compensation in the US under Illinois law, in return for not seeking punitive damages against Boeing, limiting the potential financial liability for the manufacturer."

Of course. That's the fine print. Not seeking punitive damages. In other words "we will pay you cheap so you can shut up"

20x sounds way too high. Imagine if pickup at factories is free due to scale, and the only cost is drop-off, then a return should be about two times as expensive, since sending a package to the factory is no different then someone's home.
This is the normal procedure in the Netherlands as well, for I think all-but-one of the package delivery services. If you're not home, delivery goes to one of the neighbours (could be 5-6 houses away if the driver already knows that that one is at home). Might not be common in the inner cities, but definitely in towns and suburbs. Good for social cohesion, as otherwise we wouldn't see most of these people for months at a time.

It's common to such a degree that many of the shipping forms on webshops have a dedicated field to indicate that you don't want this, though I've never felt the need to use this; definitely more convenient to walk over to the neighbours than to a pickup point.
awk is always a struggle for me to re-learn, but sed is simple.

I basically use it for simple text substitutions; in that case it is the same as what I use for vim editing.

I wish COVID lockdowns never finished... Sooner or later life might force me to take one of American-quality death machines - not like airlines will be giving a choice exactly.
Chip shortage unlikely to ease until Texas Instruments ramps up output
The comment is negative and incorrect

all of the js frameworks mentioned are view layer libraries. i.e. they create html. Hence they need a DSL for writing templated html, which will be used for generating final html

Hence, it is completely natural for them to offer a custom DSL as html does not have standard way of expressing those concepts.

Since each js framework has its own idiosyncrasies and motivations, custom DSLs reflect it.

If you were to go around and make a new js framework, you too are going to create a new DSL
Exactly, I don't understand your comment 'some people don't have so much compensation' in response to discussion on the cash/stock split and whether it matters?

I don't disagree with you, it's just.. not relevant? Obviously if your compensation is too low to invest anything, you need it all in cash. It will be anyway. My suggestion was that cash is king as it's flexible anyway, so that's not even incompatible.
I use Cloudflare's DNS (1.1.1.1) and changing it to Google's (8.8.8.8) fixed it for me.

This page also doesnt load for me https://dns.google/
(points to 8.8.8.8 and 8.8.4.4)

Changing my DNS solved the issue.
Not sure what was happening.
Somehow a number in a database is more reliable than something tangible like crypto.

What if the server gets nuked? Well, it's still verified by several other servers, I suppose.

Trust? I've had this situation once where a check just disappeared. The bank that wrote the check saw no evidence of it. The bank that I gave the check too also couldn't verify it existed. It later bounced and someone called me to tell me to pick it up at a bank branch. The person writing the check wrote another one. That one suddenly went in twice but I didn't call customer support for that for some reason.

So I don't trust banks at all and currently keep my digital money in 6 different accounts, not including crypto.

This is back before the fringe were 1) named the big bad of the media, and 2) networking with each other on the internet. The fringe believed the same stuff they do now (in broad strokes) and was just as large as it is now.

As a collector of John Birch and Communist blacklist material, none of this is new. Look up Eustace Mullins.

edit: or for the mystic, Savitri Devi.
Like in the Great Recession a side effect, or by design, was a banking squeeze and consolidation from small/medium in favor of large players.

The chip/ship supply shortage is again squeezing small/medium in favor of large players.

Very little margin and too much optimization/efficiency is bad for resilience. Couple that with private equity backed near entire market leverage monopolies/duopolies/oligopolies that control necessary supply and you have trouble.

HBS is even realizing too much optimization/efficiency is a bad thing. The slack/margin is squeezed out and with that, an ability to change vectors quickly. It is the large company/startup agility difference with the added weight of physical/expensive manufacturing.

The High Price of Efficiency, Our Obsession with Efficiency Is Destroying Our Resilience [1]

> Superefficient businesses create the potential for social disorder.

> A superefficient dominant model elevates the risk of catastrophic failure.

> If a system is highly efficient, odds are that efficient players will game it.

Hopefully that same mistake is not made in the future. It will take time to build up diversification of market leverage in terms of chips for availability. Hopefully we have learned our lesson about too much concentration, with that comes leverage and sometimes a "gaming" of the market.

This chip shortage, and all the supply chain problems during the pandemic as well, will hopefully introduce more wisdom and knowledge into business institutions that just because things are ok while being overly super efficient, that is almost a bigger risk than higher prices/costs. Competition is a leverage reducer. Margin is a softer ride even if the profit margins aren't as big.

yes, but recently the gnome devs are effectively handing them pitchforks in the hopes they will go away.

The Gnome-DE has made some brutal horrible design decisions _IMO_ in the last few years (more than just the horrible pastel colour scheme).

That's not to mention the Gnome-foundation who seem to have split focus as to what their primary goals should be.
> Please leave your echo chamber. Not everyone uses IDEs.

You are so wrong about embedded development I don't know where to start.

Trying to have a fully command-line development path requires you to actually fight with most chip manufacturers (this has finally gotten better in the last 5 years as basically everything has converged to ARM Cortex-M which is supported via official gcc releases from ARM).

I can't think of anyone who developed for a PIC without MPLAB in the last 20 years (probably 30, but I'm being nice). Well, there are some people who didn't use MPLAB, but they used IAR or some other IDE.

Keil is the standard for your ARM processor. Every manufacturer supports Keil first and then worries about whether you can use another IDE. The raw toolchain is almost never tested.

Nordic forced you through Segger Embedded Studio but now has thrown in behind VSCode. Fortunately, you could generally peel out the pieces you needed for command line development.

And the ones who didn't fall into those categories generally bodged some horror together using Eclipse.

Even as far back as PowerPC and ColdFire people were using things like CodeWarrior. Command line things like Cygnus were not common.

I would suggest you get out of the HN echo chamber and realize that the vast majority of software development is done on Windows where "pointy-clicky" is the rule and "command line" is anathema.

The solution is a complete paradigm shift on how you "refuel".

With an EV you don't go to a "refuel station" every time your charge is around 5% and charge it all the way to full like you do with ICE vehicles.

The solution is that you charge everywhere. Reliable and ubiquitous destination charging.

Going to the supermarket? Charge.
Going to the mall? Charge.
Parking at the office? Charge.
Parking at home? Charge.
Park at the curb? Charge from the streetlight.
Arrive at the hotel for your trip? Charge overnight.

None of these need to charge your car from 0-100 in 5 minutes. It just needs to give you more charge than it took you to get there and the net result is positive.

It doesn't need to be a 350kW mega-charger with water-cooled wires to prevent overheating. A 11-22kW AC charger is more than enough and costs a grand a pop to install.

The only time you actually need fast DC charging is when you're doing road trips that are longer than your EV range is. And even in these cases your car navi should take care of it for you. (Most don't do this properly, some do, but it's mostly software).

All the other times you're charging a bit every time you stop somewhere. For example the supermarket I shop at weekly is about 20km round trip, they have a 22kW charger and my car can pull around 7kW from that. After a half-hour of shopping, I've got more charge in my car than I had when I left home.

If I go to the local McDonalds drive-through, I can use their 350kW DC charger and usually need to unplug before my burger is done and brought to my car.

I got diagnosed as an adult.

Before then I spent my life being unable to put any time or energy into something for more than a few hours, and then I got bored and could never focus on that thing again. I couldn't do homework, I couldn't study for tests, I couldn't do much at all unless it was something hyper interesting that I could focus on it for a few hours before it became boring again. Even if I locked myself in a room with only that thing I couldn't focus on it.

Then a decade out of high school and after struggling with finishing the last bits of college so I could graduate I got diagnosed. The pills they gave me meant that suddenly I could sit down and focus and finish tasks. Suddenly everything that was impossible before was now possible. I could sit down and do all the homework no problems. I could sit and learn programming on my own no problem. I could perform at the software engineering job I got thanks to that self study no problem.

If I stop taking the pills I stop being able to do all of those things, even if I go months without, so there is nothing addictive about it at least for me, I just can't perform a job without them. I just take them because I want to get things done, I've never felt a need to take them to have fun or so, if I don't work I don't take them.

I think the question was asking about internal function calls. For external data interchange, ISO8601 is the only sane option and deals with all known timezone and leap second bollocks.

How to Start a VPN Business?
Is it worth investing in a vpn business nowadays? I doubt it would be very profitable. Maybe if it were 5–10 years ago and you were getting in the business while it was young, sure it could’ve been a great opportunity. But today there are hundreds of different VPN providers, and very few are well known today. Unless you could get a ton of funding and then provide something much better than other providers, you can’t really compete with paid VPNs.
