Quite far - miniaturization of nuclear reactors is generally quite hard.

We haven't put much effort into miniaturizing terrestrial reactors, and naval reactors have other design concerns which limit, but space reactors are a good gauge of the state of the art. From the (production!) American SNAP reactors of the 60s and the contemporary (production!) Soviet BES-5s, to the current Kilopower design studies and prototypes, there's been basically zero progress in reducing size. Fission has some hard floors on reactor (and bomb) size, because of the logic of criticality.

That design floor for power reactors is quite large - the core itself is usually on the order of 50-75cm long by 20-30cm diameter, but the heat-to-electric conversion machinery and, more importantly shielding, will quadruple or quintuple that length.

And that's with the cheats enabled by space applications, where you only need to shield in the direction of the spacecraft. For general use a similar design would fill a shipping container, like the linked microreactors tend to.

Fusion is maybe a more plausible route to small power sources on the order of decades, because there's a clear parameter to tweak: magnetic field. Better superconductors -> stronger magnetic field -> smaller minimum size.

> you could argue that all the big cloud providers could easily compete with Cloudflare and crowd out their proposition.

I would definitely argue the first point here, but not the point about crowding out. You said it yourself, there's totally room for a Cloudflare to win on UX/DX, and other areas like cost. This is the strategy the CEO mentions when he's quoting Christensen, and coming up from the bottom to compete with the big dogs. It's also why AWS will make more in a day than Cloudflare does in a year though, for now..

Why can't Google work on improving `contenteditable`? It would benefit so many and the problems are well-known. It's probably even used by Google somewhere
Uber, Lyft want more public subsidies to meet California EV mandates
Exactly. This is a situation similar to PEVs, where the technology is mature enough to make things work for a decent sized chunk of the market, but what it lacks is investment by someone with the necessary vision to see the benefits of apps rather than someone who is approaching the problem from a purely cost cutting/revenue maximization point of view.

For example, why I do need to wait until a waiter notices me, then have them bring me a bill and dissapear, then wait for them to come back to collect the bill, then wait for them to come back and bring me a receipt? That is often a 30 minute wait when you are just trying to pay and get on with your day. Why can't I swipe my phone, have some RFID tech embedded into the table present a bill, I pay and then leave. That is a 10 second process instead of a 30 minute process.

And you can still have humans around to make sure things are going smoothly and to resolve issues, but there are many portions of the dining experience which would benefit from apps instead of waiters. Think -- why are you handing a stranger your credit card? Why can't you order ahead? If you know what you want, why can't you order right when you sit down? Why can't your phone buzz you to tell you your table is ready. Think of all the information the phone can provide about the menu items -- not only pictures of the meal, but nutritional information, which farm an item was obtained from. Possible substitutions. All the stuff that you have to deal with the waiter to find out. Why do you need to wait for a waiter to come by and tell you this information? Why do you have to wait to hear the specials instead of looking them up? Or cost of market-priced items. There are whole worlds of added value that apps can bring to the dining experience that would simplify life for both waiters and customers. And all of this can be integrated into reservation/review systems for a tech stack that can provide all the info about a meal, handle meal ordering and billing, handle reservations and seating, and aggregate reviews. And the staff can still be there to greet you, to bring you your food, and to resolve any problems you may have. They just don't need to wait on you, constantly polling to see if there is something you need.

The moment someone with vision approaches the problem as something to add value to the customer and give them a better overall experience is the moment app-based dining takes off.
"Never" is bold statement, bottom line current battery technology is lighter than current fuel cell technology in production vehicles while being simpler and more cost effective.

Please let me know when that situation changes I am not confident in either technology to state it will never happen.

I worked in this industry in a few ways - indirectly (my family owned and operated restaurants), directly (working in my family's restaurants), and adjacent (I ran product for a restaurant reservation platform). There's a couple of dynamics to be aware of here, some of which have been called out:

- It's a rough job, and the labor economics are all skewed. Even pre-pandemic restaurants were struggling with balancing tipped pay with kitchen pay through a variety of approaches. Removing tipping had very mixed results.

- A lot of restaurant workplaces are very toxic, through a combination of the culture, bad management, etc. While there are a lot of small businesses where the owner/manager are bad, restaurants have disproportionately high staffing requirements, which means that the bad managers impact a larger number of people

- Lack of career advancement. At the low end of the restaurant market, people tend to just age out after early adulthood, or take a management track job. At the mid-range of the market, you might bounce around from place to place, but there's not really a path up and out. At the high end there's the most opportunity, but even then the salaries are not that high, and many of the better paying FOH jobs (captain, somm, GM) have been consolidated down to reduce labor costs

- Restaurants are not confident enough yet to understand what their business looks like in a post-pandemic world. That is making them hesitant to make transformative shifts like salaried servers (non-tipped) or investing in career development for kitchen staff. It's a lot easier to contemplate these things when you have a general sense of what the next few years look like, and I think there's just a general sense of unease about what comes next.

I love restaurants, it's something I really enjoy, and while I understand the people who just want to get fed and get on with their lives, I think the hospitality aspect of it (for me) can be nice. I think the industry as a whole has been structured unsustainably for years, though, and the pandemic just accelerated what would have become clear over the next 5-10 years.

EDIT: one last factor - I think there was also an ever-increasing shift towards higher expectations from customers. Shows like top chef, better access to ingredients, and casual chains with higher standards have raised the bar for everyone. I think that's good for diners, but there's a lot of restaurants that were already going to struggle to compete and the pandemic also is accelerating their demise.
Not op, but that's obviously in case you need to do something more complicated than returning false later. It's good practice
"Restore" is reboot. Usually these are called "watchdog circuits", which you may have heard of from more mundane embedded applications.

Once you've rebooted, yeah, you need to copy over the shared state from another of the processes.

The point is electric cars with a 200 mile range and a significant electric road network simply makes internal combustion engines obsolete in a way that even a 500 mile EV doesn’t. Semi’s are a bonus at that point.

Anyway, electric rail is just down to the standard rail vs road brake down we already have. Roads are point to point without extra loading or unloading steps. Even with expensive gas and cheap electrified rail you still see a lot of long distance trucking. Long term with either electric highways or self driving trucks it’s going to favor roads even more let alone both.
Blackmail is a gun with one bullet that can only shoot one target. Once you release the information, you can never get paid. Any leverage you had is gone.

So if the goal is to get paid, releasing the information is actually counter-productive.

Blackmail is a game of chicken.
A lot of people know basic HTML/CSS and the next generation is learning it in their computer classes, but there aren’t many tools that let them leverage it to build actual websites. If there were, people wouldn’t be so forced into proprietary, expensive solutions. And a lot more people would realize code isn’t that hard. That’s what we’re trying to do with primo (https://primo.af).
Correct. This adds a point of centralization, which defeats the entire purpose of cryptocurrency. As far as I can tell, cryptocurrency is based on wanting (1) a shared database that (2) can be updated by anyone within specific rules and (3) doesn't require anybody to trust anybody else. In the same way that low-trust societies have a much bigger overhead as a result of the lack of trust, I do not think cryptocurrencies are feasible while holding to (3) without massive, massive expenditure as a result.
I love it how we can do this complex stuff. Though being a 90s kid, I imagine doing a T9 based brain-computer interface would be easier and faster.
This mode of argument seems odd to me. Google is announcing a solution to the problems they were having with the platform. Wouldn't the criticism "Perhaps the browser is the wrong platform for document editing" only be appropriate if Google was complaining that they have been unable to fix the problems?

The fact that, while developing for a given platform, you can encounter problems and fix them, doesn't seem to imply that there's something wrong with your choice of platform.
I mean, you probably won't like this answer, but I don't think you should be writing a XUL-based app in 2021 if you want it to be useful, as opposed to for fun. XUL is 25-year old legacy technology, and using it is an exercise in retrocomputing.

Looking for a Technical Partner
Hey HN community - I'm looking for a partner who can code (fullstack) and loves building interesting products. I can code myself and have held IC/TL positions at FAANG companies but am slower than desired and better suited to work on marketing, biz dev, product facets.

I have developed and looking to develop combination of new / innovative products that don't exist (e: launched esyvite.com early this year) and some existing products that are out there but they could use some tweaks and become massive "passive" recurring income generators.

I currently lead product and tech at a fintech.

I think there might be an inflection point where someone transitions from "personal sovereignty" through a gradual decline of choices and capabilities. Sort of a movement to more dependence on others. Could be a bumpy ride for a bit.
My practice for storing large files with Git is to include the metadata for the large file in a tiny file(s):

1. Type information. Enough to synthesize a fake example.

2. A simple preview. This can be a thumb or video snippet, for example.

3. Checksum and URL of the big file.

This way your code can work at compile/test time using the snippet or synthesized data, and you can fetch the actual big data at ship time.

You can then also use the best version control tool for the job for the particular big files in question.

its a pity bitcoin devs are so opposed to changing the protocol. So much research has been done showing the feasibility of increasing bitcoins throughput. Xthinner for instance is capable of compressing bitcoin blocks by up to 99% using bloom filters [1]. Much of this research was conducted on the bitcoin fork, bitcoin cash, by people ostracized from the bitcoin community for wanting to explore these ideas.

Impressive! And excellent coding style. I attempted to write an RTS at least 5 times in the past 30 years and could never stay focused, so I'm seriously impressed by this. In C no less!

How did you stay focused? And how did you segment the work? It requires progressive refinement to coordinate all of the systems. Wondering what order you took.
Your ideas are very much in line with Stoicism (I can't control the world, but I can control my reaction to it), the teachings of Jesus Christ (Matthew 6:25-34 lilies of the field), Buddha (Discourse on the Forms of Thought), ancient Hindu wisdom (lookup "Vāsanā" for starts) and modern Cognitive Behavior Therapy. Some people like to focus on one, but I have learned from them all.
Use SD cards. You can fit probably a petabyte of information in a typical storage cabinet. If the environment is controlled, I don't think you'd run into problems with data corruption or being unable to read data. And to hedge against that, you could just duplicate the data onto multiple SD cards, and store them in different areas - sort of like AWS AZ's.
Yep. We occasionally get emails that look like they're from other organizations in our collective to phish for information.

As a ML/DS hiring manager, I have found that the biggest challenge for finding the right talent is having to flip the rock and try hard to "spot" the hidden gems.

Must also be my personality, I reviewed everyone's resume (not just the ones filtered by the recruiter), hoping not to miss someone, anyone good!

Concrete example:
a) someone from University of Wisconsin-Madison, Phd in Math, data scientist in personalization/pricing etc. great experience. Although I was looking for someone who may have some experience in voice NLP, I thought... perhaps I could talk with this person.
b) someone from MIT with Phd in stem, strong researcher, listed some papers hard to understand, but I thought about it for a few min, the hard-to-understand paper might be relevant to what I need.

However, my recruiter disagreed. They were screened out. I begged to talk with them.

I hope to help people to get really "spotted".
CM isn't good for the web, but it is pleasing in print IMO.

I do agree though it has been abused a lot as a status symbol. Back at MIT, having a resume in CM spoke "I come from a science/engineering background" right off the bat, while having a resume in a Microsoft font spoke "I go to the business school".

If you move away from CM, great, there are lots of better web-friendly fonts, but don't go to TNR for f*ck's sake. TNR is awful. Unfortunately some publications have gone down this hole.

I like Crimson Pro of late. It looks VERY pleasing on mobile LCD/LED and e-Ink screens, has the effect of making your device feel like a quality printed book, and has a full selection of weights.

Based on inspecting the DOM of the read-only preview document they link to, my guess is that they will be using traditional DOM elements for much of the editing UI. There appear to be many empty DOM elements that are there to hold various toolbars and other UI elements. And for what it's worth, there seem to be empty DOM elements intended to be read by screen readers.
Geez. I wonder if the M2 will just be higher clocked and more cores or if they’ll improve the arch even more?
> more that there are legitimate reasons why and editor might not be the right way forward.

I think this is true, and certainly didn't mean to suggest otherwise. It's just that "a (good) editor wouldn't improve my output" is approximately never true.

Whether that improvement is worth whatever it costs you to get it is a separable question.

Web 2.0 enabling web apps was always a myth. There have been web "apps" since the 1990s with CGI. XMLHttpRequest merely allowed for the moving of some of that logic to the client side.

In that respect, we've been working around the "page" paradigm since the web was practically born. It was a flawed analogy because, even back then, screen sizes and display tech varied among users. Designers still approach web design as if they are designing for print. I've always maintained that if the web were based on a vector technology (think PostScript, but obviously not PostScript) we would be in a much better place both design-wise and accessibility-wise. Content would flow in a much more controlled manner with much less room for browser interpretation and second-guessing. But people were still clinging on to the write once run anywhere (ahem, Java) naivety of the day. And likewise they really thought that you could divorce presentation from semantics and... have something that just worked? I guess? Just sprinkle on some afterthought CSS tech crap and no one will ever notice that the entire thing is flawed at a fundamental level.

What Is Local SEO and Why You Should Use It Now
Local SEO is a digital marketing strategy to influence SERP rankings with local signals on Google’s local search landscape. While it still falls under the general SEO guidelines, Local SEO has a specific and targeted intent to sway local searches.
Input methods are managed by the OS, the browser delegates control. It can't do that over a simulated input control rendered on a canvas. Also what I mean is that all these are problems already solved by browsers that follow w3c recommendations, custom rendering solutions will have to reimplement everything without access to OS APIs that make many of those things possible in a unified way.
It performs poorly in either case. For one, Javascript APIs have significant marshalling overhead.

Secondly, Canvas is often "hardware-accelerated", which can make some things faster, but also slower because this kind of immediate-mode drawing doesn't match the GPU interface well. It's particularly slow at vector graphics. Some effects would require pixel readback, which is slow for the same reason.

> Personally, I would be happy if Canvas just let you put raw pixel data on the screen and did that as well as possible.

Drawing cached Bitmaps is relatively fast in Canvas, if you don't need too many calls. Getting arbitrary data into such a Bitmap is slow, so if you want to do it every frame you may run into issues.

It's not an abdication of responsibility, as I don't recognize the responsibility or the authority of mob rule in the first place.

You're right that it means someone else will make the decision for me, and it will be enforced against me with violence. I'd rather not participate in it at all, because that gives the whole process the appearance of consent and legitimacy.

I don't actually think democracy is a good way to run things, and I don't consent to the application of it to me, or the demand that I participate in it, or the insinuation that I have some responsibility to do so. I never signed up for this and don't want it. My participation is implied/tacit acceptance of the outcome even if it is different from my vote, and no such acceptance exists.
Sixty years on, the most interesting thing about the case is enthusiasts' refusal to consider the most plausible explanation because it doesn't deliver the same satisfaction as less likely theories like government conspiracy. Granted, the incident took place in a society where the government frequently covered up fatal accidents, but that environment doesn't make the wind slab explanation any less likely.

There was a discussion a while back on "trapped priors" in Bayesian reasoning, where you might "correctly" update your beliefs in the wrong direction based on your subjective experience of evidence that should contradict your prior beliefs (1). It seems like you see this behavior everywhere, these days, especially when it comes to conspiracy thinking: any data can be taken as evidence to support the conspiracy theory, whether it's "Q" or a sixty-year-old backcountry disaster.

Sure, people should be able to identity what is a valid source and what isn't. It's fine to ask about what classifies as good or bad sources (format, publications, etc), how to search, or whatever.

But this isn't what happened. It wasn't "help me to find good articles on the topics like these" it was "citation needed." In fact, I don't think I have EVER seen anyone ask how to find reputable publications on a certain topic.

I also like sources, and when I'm saying things that have provable claims, I like to back them up. Still, what I DON'T go into the comments for is a long list of people going "citation needed!" I come for interesting debate and perspectives. But that's not what i'm getting—i'm getting people disagreeing with each other by putting the onus on the other party.
I get the point. In terms of accounting principles, you're right, technically.

But it doesn't drive home the message that more code doesn't mean more asset. Having a developer write more code doesn't automatically create more value. The value is in what the code does, not the code itself. And a developer can actively harm the codebase by working on it. You can pay someone to improve it, and the end result is a decrease in value, not an increase. I'm not sure there are other asset classes that behave the same way. I could be wrong.
