I’m only an armchair physicist but from reading the Wikipedia article on artificial gravity the main blockers to having this happen appear to be the amount of power/fuel required to sustain gravity and the size of the spacecraft. Under the centripetal model it seems that the bigger you make the craft the less that is required for gravity, but then you have the problem of getting a giant spacecraft off earth. It seems like one of those problems we have a theoretical solution for but the cost/technical limitations make it pretty infeasible currently.

Maybe the first realistic implementation will be something along the lines of only having the sleeper berth with gravity and everywhere else is weightless.

I am a backend engineer who has been working in the mobile gaming space for many years now. Most of the focus today for mobile gaming backends is to scale to millions of players while offering low latency and real-time interactions. Have been following the development of this book through its beta and having read it now, I think it is fair to say that this book is worth its weight in gold. I can relate directly to all the challenges faced over the years in implementing a real time distributed database _like_ functionality with a high read _and_ write throughput, both custom and off the shelf. Extremely well written.

It sort of depends on distance, in reality it depends more on circuit noise and attenuation. If you have a really quiet circuit and high gauge high quality copper you will get a good signal to noise ratio which will give the modem margin to train to.

The curves used to calculate speed over distance make bulk assumptions.

Why? By what standard does anyone weight "historical context"? It's your supposition that there would be any affect at all to international workers.
It is obviously better to be happy than sad, but you've ignored 2 facts: 1) humans are very bad at appreciating what they have, and 2) humans are very bad at predicting what will make them happy. People who are tired of this "grass is always greener" capitalist world and yearn for simpler things are doing exactly that, thinking that the "grass is greener" on the other side when it isn't. All people will eventually become miserable in the wilderness because of some tragedy, then they die, that's how nature works. Thus it is more important to have vacciness and antibiotics than to be happy because your brain is stupid and irrational, doesn't appreciate what it has, and fantasizes of edenic states elsewhere that don't exist.

Also, you know which one you would pick. You've already picked it. As technology increases, there's nothing preventing you from slowly moving out into the wilderness besides an acknowledgement that modern comforts are worth it.
Microservice Testing: Unit Tests
Not to be rude, but of the active AI researchers I've seen state an opinion, almost all of them are critical of the Bostrom book, with the main critique being (iirc) that rapid/exponential self improvement is presented as an inevitability when there is very little reason to think that this is the case.

Not to say that Superintelligence isn't worth reading (as you say, it's a pretty enjoyable book), but I think it's important to point out that Bostrom's views are not broadly accepted by the people actually writing ML/AI code.

The primary concerns I've seen from the community are

a) issues with research itself (lots of derivative/incremental/epicycle-adding works with precious few lasting improvements)

b) issues with ethics (ML models propagating bias in their training data; ML models being used to violate privacy/anonymity)

c) issues with public perception/presentation (any ML/AI tech today is usually incredibly specialized, built to solve a single specific problem, but journalists and people pitching AI startups frequently represent AI as general-purpose magic that gains new capabilities with minimal human intervention).

The WMF does a great job on any code used on or produced for WMF servers, but for the other extensions listed on mediawiki.org, it's a smorgasbord of XSS and SQLI. A lot of those are git hosted by the WMF too, so don't use the hosting location as any indication of security.

The state of things seems to be that we've made really good progress with deep learning/neural networks/MLPs with the result that there's impressive fuzzy pattern recognition based on supervised learning. Which is great and has a lot of practical value but it's just one set of related techniques.

Cognitive science, on the other hand, has arguably not made a lot of great progress. We don't really understand how we learn. We don't really understand how language works. Etc. But arguably a lot of this sort of thing needs to be part of "AI" to get beyond problems that are amenable to pattern recognition.

Any plan to provide find compatibility for drop-in replacement? My find/locate usage patterns are not worth learning new sophisticated tool for 5sec speedup once a week, and I suspect that I’m not alone. This is the main problem of new tools — not repeating the old-familiar style makes it unattractive for non-aggressive users.

Side question: why is speed important? Which tools use fd to gain required performance?
I've found that fzf has replaced all uses of find for me except in scripts. fzf has the benefits of being bound to a single key binding and showing me results as I type, rather than after the command runs.

> it's much safer in that circumstance to have a frequently rebooting instance

I actually happen to agree with you in principle on this, and it's at the root of my current side project.

But sometimes you just don't have the flexibility to fix or replace the app. Ops engineering, like any other kind of engineering, is about dealing with real-world constraints and making the most of the resources you have. Most apps, on some notion of a fragility spectrum, are far closer to fragile than to antifragile, because fragile is the default, and extensive stress-testing to understand and plan for all failure modes before a production deployment isn't typically feasible. At that point, if you can't fix it, you have to work around it.
Exactly. Especially once you've come to a good understanding with a standard *nix tool/command.
>The problem with that idea is it makes no sense from the standpoint of Roy's epiphany, which is ultimately the moral of the movie. If Deckard isn't human, there is nothing noble about Roy saving Deckard.

Plus the whole point is in the ambiguity (including of the noble act).
Awesome stuff! I don't understand why this post isn't more popular around here?

This is exactly what i need. For too long i've felt that there is too much magic happening in the js and front end tooling world. More often than not, tutorials and guides just brush the basics aside and expect you to be fine with cloning the newest github biolerplate with x and y features and get on with it. That is usually fine until you hit a bug, or some non standard behavior because of the tooling setup. I think if you really want to learn for example react you owe it to yourself to learn the basics or you'll regret it later. And besides, most of these boilerplates usually bring considerable feature blot with it IMHO.

I've grown too comfortable relying on prebuilt boilerplates. Time to get my hands dirty. If just for the learning experince.

My favorites are the 1 star reviews of national parks. Such reviews have gotten some coverage lately in online outdoor communities. They tend to be either wilderness aficionados complaining that too many people are there taking pictures, or unprepared visitors complaining about the lack of amenities. To be clear, I can understand both (particularly the former, geez Yosemite), but both are examples of realistic expectations not factoring into the reviews.

> First tram up on a powder day at Snowbird deserves all 5 stars but after that, it's a legitimate 1 star experience.

If you're a spoiled local like me, and only 3 feet of powder, only in the chutes where everyone goes, if that's the only thing worth considering, then I can understand your statement there. But even though I'm spoiled, I've never had anything close to a 1 star experience at Snowbird even on the groomers. I've skied there in 30-below when the snow actually stops working, and I still wouldn't call it 1 star. 1 star is what you get on the east coast and in California, when you compare it to Utah. We don't even have 1 star anywhere in Utah. Anyway, hit more Mineral Basin, I can usually find powder there days after any snowfall. Or find a friend with the early bird pass, Tram opens at 7am for a few "lucky" people.

I’d add a third metric: reputation of the reviewer. Yelp is full of glowing 5 star, and damning 1 star reviews from people who only ever write that one review. They tend to be short, one or two sentences, and once you start looking they’re everywhere.

Reputation can mean a lot, beyond just knowing who someone is.
Wix Code
This side-steps the question of why these smartphones, with more computing power than desktop computers 15 years ago, can't use new mainline kernels, while desktop computers 15 years ago, and desktop computers today, can.

It's few different factors, like: Smartphones are harder to reverse-engineer, because of the smaller parts and greater integration and fewer common interconnects. Smartphones are more diverse, and each SoC "architecture" is significantly changed or replaced after just a year or two.

There's never enough time and mindshare for third-parties or the vendor itself to write high-quality base system drivers for these things. There's just crappy vendor "BSP" code that's never good enough to maintain support for multiple generations in the same code tree. It's always "fork and add messy hacks until it works". There's never enough time and motivation to make any of this support code good enough to be reused.

Some kernel maintainers have tried for some time to convince "enterprise" linux distros to keep up with newer kernels, and apply more of their testing and validation effort to newer kernels, instead of just maintaining one old kernel on their own for most of a decade. This enables more sharing of this effort between multiple distros and other users of the linux kernel. To some extent they have succeeded. But where they have failed, at least the "enterprise" distros did maintain the old kernels they distribute.

But these smartphone SoC vendors don't even do that. They really give zero fucks about software quality. It seems to work, ship it, move on to the next iteration because it has to make it to market in X months to keep up with the competition. At that rate, third-parties can't even come close to keeping up and justifying the investment of effort in reverse-engineering (which has been done for a lot of desktop hardware).

fzf is fine for searching just for filenames, but it does nothing else that find does.

It can't even search specifically for directories, as far as I can see, nevermind searching for files/dirs with certain permissions, ages, etc.

It's also uselesss for non-interactive uses such as scripting.

I like fzf, but it's really not anywhere close to a complete find replacement.

> Did you do a benchmark with `--threads 1`?

I did. You are right, multi-threading does not give a linear speed up, but it makes fd about a factor of three faster on my machine (8 virtual cores). With `--threads 1`, fd is on-par with 'find -iname', but still faster than 'find -iregex'.

They’re selling best effort service at a fraction of the price of what dedicated bandwidth costs.

Unfortunately, what they are advertising is something quite different, and the claims made are often wildly inaccurate.

Over-subscription of shared resources for efficiency is one thing, but misleading advertising is something quite different. Frankly, if they get their maths wrong and consequently fail to provide the expected level of service, that's on them anyway.
They can and do provide guaranteed speeds; it costs a lot more. They can't provide guarantees (or 99% guarantees) of existing advertised speeds at anywhere near the existing price structure because the economics are based on overselling.
