Here at the bars in Honduras, people don't mask or distance at all, at any hour (including the bartenders who are all unmasked). But it probably does help that they have to go home earlier, so that's sympathetic reasoning.

That's a nightmare. See "Hyperreality"[1], if you haven't. That may be the future of AR. Especially if Facebook is involved.

Do you have reoccurring todos (or is that done by reoccurring calendar events)?

I am currently paying $0 for ToDoist, but I'd be willing to pay $10USD/mo for ToDoist + analytics (needs iOS and web). I want to know how "good" I am at completing my tasks each day and which reoccurring tasks are often delayed or rescheduled.

I don't care about calendar integrations or notes. The encryption is neat, but I don't trust it and I don't capture any hyper-sensitive content in my todos/calendar/notes anyways.

This has happened to me a couple times. Feeling tired of what I call the "tech rat race".

Both times some time off and working on an idea for fun sparked interest again. I would say if you take time off, don't feel pressured to do anything tech related. At some point you may get a creative idea and then just follow that. One time I finished a gameboy emulator I had started a few years ago, the other I made a little video game. And if you don't get the urge to do anything tech the whole time you're off, at least you'll have some R&R to go back to work with a fresh mind.
> Even that is not true, since you can always combine electricity from multiple sources to form your base load, and there's no law of nature saying that the base load must come from a single source.

No one is saying it must come from a single source? Combining electricity from multiple reliable sources is fine, but there will be times when the sun isn't shining and the wind isn't blowing so you need to be able to meet energy demands in those cases. The only clean solution is nuclear (and hydro where available).
it ends up being cheaper overall if you have high utilization of your provisioning since the per second fee while a function is running is cheaper. using https://calculator.aws/#/createCalculator/Lambda, if you have a steady 1 request/s and each requests takes 1 second, 2592000 seconds in a month. at 1024mb, i get 36.52 for provisioned and 43.72 for on demand. With autoscaling...you wont get 100% utilization, but it probably ends up being close enough to a wash
Seriously this is an amazing shift of the Overton window.

That was my experience too and yes, it gets better. I went from "I don't understand it" to "I hate it with a passion and want a proper typed language" to "uh okay it's caught 2 bugs I overlooked. This is useful" during my first project.

My advice: accept it's completely alien and is going to take effort to learn. I found spending a weekend sitting down and reading a theoretical guide was useful; there's good recommendations further up this page. Understand there's different levels of applying TS: one of its maintainers told me to start off slow and use `any` wherever I didn't know what to put. I pooh-poohed that because everything should be typed in a typed language but he was right. I have a few `any`s and a few `x as Type` where the code can't work it out because something's gone wrong. It works and my next project will be better.

I still have no idea (and haven't found any tutorials) on how to type form data (DTOs) or any object where stuff is structured but can be optional or required. How do you validate the type definition? What about HTTP responses which might have data in multiple structures - how do you type each of these depending on what's received? All answers welcome.

I will get there. And so will you. Onwards!

Aside: I got roundly mocked on a JavaScript framework's discord asking questions about edge cases to help me build a mental model of the language. Apparently it's "b.shit" and "questionable" and "weird way to learn the language". Well... now I know them I can infer what's going on, understand the workarounds used and why things don't translate from other languages. If that's the way you learn, embrace it. I still think JS (and TS by extension) are weird in places. Neither would be my choice of language, but I'm coming to appreciate them.

We've moved from AWS to Cloudflare and I can confirm Workers are awesome. The only downside is lots of work required to get npm packages running properly. Due to the lack of Node.js' runtime, bundling, shims and stubbing required to get stuff like "fs" and "net" compiling. AWS is more mature, has a better community support around it and generally the tooling is more stable. Workers are quickly catching up, though, with great new additions such as ES modules, custom builds, Miniflare, etc.
Sounds fascinating actually. Any good articles you recommend about NK doing this?
Which is nowhere near as big a deal as it sounds. The damage it will do (on average) if glassed and buried 100ft under ground is absolutely negligible at the scale we are talking about (global climate change and energy in general).

Yes, there's a 1 in 10000000 chance that 2000 years from now industrial age humans recovering from the apocalypse might dig a well in exactly that location and thousands will get sick with hundreds of deaths. You could multiply that by a hundred thousand cores and it would still be negligible compared to the hundreds of millions likely to die due to climate change in the next century
> Switch to renewables and drastically increase energy costs, which will trap millions of people into poverty, and put millions more in risk

This feels like a bad faith take out of the gate (whether or not it's intended)... are there no mechanisms for subsidies to abate these issues? are renewables more likely to increase wealth gaps than other fuels?
This is a good response to drill down on, because the poster's assessment of the purpose is accurate.

Yes, much of both TypeScript and React are there to minimize performance costs and improve software reliability in tens-of-thousands-of-lines-of-code projects: TypeScript is using static type safety to replace the need for dynamic typechecking (decreasing the expected runtime error rate and the runtime cost of dynamic type analysis; static typing tells you both when you must runtime-coerce types and when such coercion is unnecessary and would waste performance). React is using delta-detection of lighter-weight objects to determine when heavier-weight objects in a declarative user interface API need to be changed, impacting performance (because a handful of equality compares against objects or plain data is a fraction of the cost of repainting every pixel in a table with pixels representing the exact same information as before to the end user).

These are problems people face, but if they are not the problems you're facing, they might not be the tools you need. Not everyone is writing the Facebook UI. There are lighter-weight tools out there that solve similar problems with less complexity (the tradeoff, perhaps, being that if you do find your software needing to scale to handle updates to represent complex, heterogeneous data or infinite streams of information, those tools might not scale easily... But how many people actually have that problem?).

"Use the right tool for the job" is one of the cornerstones of the art of software engineering.
Yes, this is my approach too - I'll take extensive notes and/or rewrite the material. The way I do thinking and learning is essentially to write things down on paper - it doesn't work for everyone, but it does for me.

I also happen to use fountain pens for it, but I think that part is optional. :)
The obvious political solution would be for a powerful nation, such as the USA, to publicly announce "An agreement must be found between rebels and government forces to eliminate environmental impacts of this ship within 7 days, with work completed within 6 months, or the USA will come in with military force, make it safe, and take the oil as payment".

This seems like the very definition of "World police".

That is not the mindset with which aviation arrived at its amazing safety record.
Olkiluoto 3 in Finland, Flamanville 3 in France and Hinkley Point C in the UK are all using the same reactor design: European Pressurised Reactor (EBR). This was jointly developed by France (Framatome and EDF) and Germany (Siemens).

All three projects are over-budget and have been dogged by delays.

I'm not against nuclear, but the cost of new (large) nuclear plants always spiral out of control. For example, Hinkley Point C in the UK is due for completion in 2026. Estimated total cost: £23 billion - making it one of the most expensive nuclear power plants in the world.

This BBC report on Hinkley Point C has some interesting facts:

Hinkley nuclear power station on track for 2026 opening: https://www.bbc.co.uk/news/uk-england-somerset-58724732

From the article:

> When Hinkley was approved in 2016, EDF estimated the cost at £18bn. Today, the company puts the bill at nearer £23bn.

The deal to build Hinkley Point C includes a fixed-price or ceiling cost for electricity known as the Strike Price:

> ...in 2016, the British government fixed that price at £92.50 per megawatt hour (MWh). The price rises with inflation and has now reached £106/MWh.

> Back then, the equivalent price for electricity from offshore windfarms was well over £120/MWh. But wind costs have fallen fast. Today new wind projects are fixed at about £50/MWh, well under half the price of Hinkley power.

> So, the big question for Hinkley watchers is this. By 2026, will the electricity it produces look very expensive?
They're ads, my guy. The search results that you ignore because they're not search results. I think it makes sense that the people selling the ad space want to avoid reputational damage of being associated with drivel.

> The real question is who is pressuring google to do this in the first place. But I'd doubt we'll ever find that out.

Well, if you read Google's statements from the article, Google's advertising partners are pressuring them to do this because the non-climate denying people buying Google's ad space, unsurprisingly, do not want their content run alongside drivel.
This matches a lot of my own experience in trying to convince people to take reasonable precautions and get vaccinated. And I was one of the first in line for my age group in my state. You have to do things to build trust first, and you have to be willing to admit that some of the measures taken are farcical and have no basis in science.

People will listen to a reasonable, nuanced discussion. They won't listen to someone who hates them.

The answer to masks being uncomfortable is to have a reasonable discussion about when masks are really necessary and which masks are good (N95), meh (surgical), or useless (cloth) and help people find more comfortable masks, take more breaks, etc. Not the Reddit way of putting up videos on the front page of their 109 year old grandma wearing a cloth mask over her oxygen mask for 5 seconds and mocking anyone who grumbles about how wearing a mask for an entire 12-hour factory shift is uncomfortable is a weak loser... missing the fact that they grumble because they're actually wearing a mask.

If we focused more on helping people comply with rules and explaining things calmly and rationally and being clear about what we do and don't know and took much softer approaches, this wouldn't be so bad.

There are still people willing to listen out there, though. But not a lot of people are interested in actually talking.

Back in the day we used to call that "double buffering".

The common Amiga implementation was especially neat. There, the video buffer was (almost) any chunk of memory you pointed the "screen" at. You could pre-render a number of complex frames, and have a high-FPS animation by moving the buffer pointer.

And yes, you could look at your own code executing in realtime. But I digress.

That's the compromise in my city. I am allowed and expected to cycle in the sidewalk along an underpass. That means inevitably that I'm going to pass pedestrians. There are signs before warning pedestrians that there will be cyclists, but many seem not to get the memo.
Kind of a lazy comment. There has been substantial progress with the latest development from NIF as well as SPARC demonstrating a magnet section that would enable ITER at a much smaller scale using fundamentally superior superconducting technology
With NIF’s latest result, we’re no longer just generating smoke from rubbing sticks together, now we got a flame.

That’s a substantial, qualitative change in the state of the art of fusion technology. Now we need to do it dozens of times per second and make steam from it, while using efficient lasers and breeding tritium from the lithium jacket.

Works kind of like the EUV light sources TSMC uses to make the highest end computer chips, except a fuel pellet instead of a drop of tin. Like so: https://en.wikipedia.org/wiki/Laser_Inertial_Fusion_Energy

How Slack Upended the Workplace
I normally don't like to pile on with negativity, but I'd argue the video does do it justice. I played with one myself (the only one I ever saw in the wild and she only had one because her SO was one of the original investors) and it was similar to what the video shows. My first experience with VR was impressive, Magic Leap was a disappointment.

The background is dark, the occlusions are bad, the hardware is large, and the FOV is poor.

Magic Leap really burned a lot of good will imo by sucking up enormous amounts of AR funding having 'demo' marketing that was at best intentionally misleading if not just fraudulent.

I'm still bullish on AR being the next platform when the hardware is ready, but I'd bet on Apple or Oculus pulling that off, I wouldn't go near anything from Magic Leap.

This about sums it up: https://twitter.com/fernandojsg/status/1017411969169555457

It's a little reminiscent of General Magic - something like the AR they want is likely to exist in the future, but I'd surprised if it's from them.

Can you imagine Steve Jobs shipping something at the quality level of that video?
It's not surprising at all.

Everything has been debundled, privatized, consolidated, streamlined, modernized. This is not "bad" in itself, but doing big public projects this way is not efficient, because this way of organization needs big volume to become efficient.

Basically we need to order 100+ reactors to get them cheap and fast. (And we need to have them use truly standardized interchangeable (modular) components. Naturally, modularity has an overhead, but it pays off if there's a long term for it to pay off. As long as we only build a few plants treating each of them as different allows for some local optimizations, but that is against large volume manufacturing, maintenance, etc.)
Of course you can. The price of energy independence is the lowest total cost that can keep up with energy demand.

The question is if fusion is really the cheapest way to do it, say vs alternatives.
If you depend on it, you should keep a local copy around that you can host if needed.

Things get abandoned all the time. When you make them part of your stack, you now are forever indebted to keeping them alive yourself until the point in which you free yourself from that burden.

The duration between when the pedestrian collapses and when the driver runs over the pedestrian is not as relevant as you seem to be implying. If someone is standing in a crosswalk in broad daylight and falls over, even if the pedestrian collapses 0.1 seconds before someone runs them over that doesn't leave the driver blameless. Why, in broad daylight, in the middle of a crosswalk, was a driver 0.1 seconds away from running over a pedestrian? That sounds like poor road design, poor driving, or another factor. The same logic applies even as we worsen the conditions: if it was dark, where was the lighting? If the pedestrian "suddenly appeared" from behind an obstacle, why is there an obstacle that close to a road and why can a pedestrian get so close that they can "appear" from behind that obstacle?

Roads should be designed so that pedestrians cannot accidentally end up 0.1 seconds (or pick your duration) from being crushed by a driver. And drivers, state-licensed machine operators, should face an incredibly high bar of scrutiny when it comes to damaging pedestrians. Yes this probably means very different road designs than the ones we have now, that is one of the end goals of this kind of effort.
It could be that they are afraid of a high MSRP scaring away customers. But this isn't 1993. There was clearly a market for $1000+ priced PS5s that would have lasted at least a year. The PS4, PS4 Pro, and PS5 offer a good, stratified product lineup to justify the higher prices to consumers.

Plus, the Switch never really competed with the XB or PS5. Kind of like with a PC, Switch ownership compliments XB or PS5 ownership pretty well. People buy the Switch for the Nintendo games, and maybe tolerate a shitty port of a game because they can play on the go. But most people seem happy to own both.
This is not a bad thing per se, but I'm growing increasingly tired of companies like Google having a policy of "we will do and allow anything that makes us more money than it costs us." Sure, today I'm protected by Google's rules against racist ads and climate denial ads and holocaust denial ads, but what about tomorrow? I don't like the rules of public discourse being controlled by whatever is popular or unpopular. Am I allowed to purchase ads decrying the ongoing war in Yemen? How about advocating for gun rights or gun control? Denying climate science is banned but selling snake oil and pyramid schemes is allowed?
To handle half the world's avg electricity use, I estimate it would take a ~3ft thick copper cable at 1.1Mv hvdc. This ignores the heating of cable which might become a problem. Also you might need two of these unless you want do earth return.

global_consumption_joules = 22848E12 * 3600

seconds_per_year = 365.25*24*3600

avg_power = global_consumption_joules/seconds_per_year

hvdc_voltage = 1100E3

amps = (avg_power*.5)/hvdc_voltage # assume shiping half the power to dark side of planet

sq_in_copper = amps/1000 # 1000A/sq in of copper

dia_in = (4*sq_in_copper/3.14)**.5

print(dia_in/12) # 3.23ft dia of cable
Functional vs Array Programming
They have to be disposed of. That creates waste. This is the same as with any other power generation method that exceeds it's lifespan. 15 years is not that different from 20 years for a wind turbine or 30 years for a solar panel.
It’s mostly poor kids who make 20-30k a year trying to get some extra pocket change. Even if you are doing it at scale you probably won’t make more than 100k
But the solution that comes out of that framing is to somehow shame drivers into being better, as opposed to making roads better.
Ask HN: What to learn after HTML, CSS and JavaScript?

> but there will be times when the sun isn't shining and the wind isn't blowing so you need to be able to meet energy demands in those cases. The only clean solution is nuclear (and hydro where available).

That claim is highly debatable. Lots of people claim that the storage necessary to overcome these generation troughs make it infeasible but they seem to completely ignore holistic cost minimization approaches using overgeneration and then conclude that the amount of storage required makes it impossible. Meanwhile it's been calculated that modest overgeneration squashes storage amounts (and costs) in massive ways. People have actually studied these things, you know...

See for example the 2018 article On the economics of electrical storage for variable renewable energy sources by Zerrahn et al.
