What is this pseudoscientific drivel? What the hell do they mean by "inject a large amount of energy" into atom? Can anybody actually explain what they created and what the properties of that material are?
It's relatively easier to iterate your data storage with relational tables though. Dynamite is great if you are sure a component just needs a k/v store, and you are sure you will never want to do a join.
Nothing ever does.
Our brains are wired to treat processing information from a physical unchanging object very differently than from a slab of glass with ephemeral content on it. Words on a printed page do stick in your head better than content flowing past on a screen.
I am so looking forward to the day we have some form of electronic book though! A series of e-paper pages that will make my brain feel like it's holding a 'real' book will be that day I switch.
p.s. I want an electronic paper map I can fold up and stuff in a pocket, that requires little energy and still allows me to do all the pinch/zoom and tap tricks I can do on a tablet.

First: none of the exact rules are written yet. But current discussions seem to suggest "Yes, this will go away" for "./services" being resolved to anything but an absolute location ending in "/services". But importing so-called bare specifiers ("lodash") will almost definitely be supported.
Honest question: Does anybody actually care that it doesn't?

This is just refreshing to read. I don't like the product, but this was a good read and detailed explanation of the issues/problems you can find of making a physical product startup. I also enjoyed the honesty and down to earth writing of the author.
Why you think you’re getting worse
That's stretching it quite a bit. You can implement shared memory multithreading on top of actor model and have all of the same issues. If you don't do that though, you won't have those issues. Same way that you can implement memory unsafe primitives on top of memory safe ones.

Youtube did the job right for sure, I agree with you there but not with a similar jest for PDF/books equivalence. Youtube killed cassettes, CDs and all other offline forms of video: on plastic and also over a format file saved on a disk. PDF is like those .wmp Windows Media Player video files that no one has the time or interest to download and then read on.

Sure it works among techies because a good alternative has not existed but the real market of book doesn't consume PDFs or ePubs. They don't understand those, and don't appear to care because it is bad un-relatable experience to begin with.

Some of this advice seems like wildly premature optimization. Splitting into multiple hosts and/or using a database service at 10 users?

At 10 users, you should be focusing on growth, not fussing with your tech stack.
At the moment I'm pausing development to focus on other things, but there are a few features needed to really make it useful.

Eventually I'd like to add in building various text corpora by parsing the entire collection of the entries, by selection of entries, and by tags / groupings. Currently, the analysis isn't taking advantage of the recursive data structure of the library.

Lisp allows spaces in identifiers, or any other character. You just have to escape them:

(defun |my + function| (x y) (+ x y))
(|my + function| 2 2)

(Or maybe write a reader macro to deal with them in some other way.)
Here's some anecdata from someone serving 1.5 million monthly users with a realtime (chat etc.) web app. Disregarding the file serving functionality, this is the entire infrastructure:

- The frontend is running on a 30 bucks/mo VPS with cycles and RAM to spare.
- There's 2 DB servers for 5 bucks / mo for redundancy.

This thing would scale pretty linearly in theory, so for 10 million users just add like 4 servers.

So about 200 bucks / mo to run your average startup's web app at 10 mil users.

Alternatively write bad software and throw 50k/mo at AWS I guess.
Great, more false hopes on dating apps for me ha! They'll look more real than all of the women using snapchat filters on their profile photos.
Do you know of actual people or governments with unfilled vacancies for low paid work in high unemployment areas?

What you describe is too easy an image to create on one's head. It's easy to convince people this is happening, as fictional jobs where the employer doesn't really intent to hire anyone is are very cheap to create. But it is hard for people to risk their families living just because they think some job is beneath them.
I too wonder how you 'densify' an electron...
I've reset them several times.

It's important to point out that it's not every time. It's maybe 5% of the time, which is enough that I can never trust that they will actually connect. And the unusual, time consuming experience is the infuriating one that dominates the amount of time I spend thinking about the product.

It's also somewhat inconsistent between the sides, the left bud is somewhat less reliable than the right one.

I have some feeling that it may be some interaction with the MacBook Pro, which has some sort of weird interaction with the iCloud account such that pairings sync between iPhone and MacBook.

>Prisoners in the US have largely been screwed into pleading guilty through a horrific bail system combined with malicious plea deal bargains

Largely implies that the majority are innocent. There is nothing to support that claim. I disagree with the way our bail system works, but keep in mind that the US has ranks very highly with respect to limits on pretrial detention in general.

>over 90% of convictions did not go to trial

That number is meaningless by itself without knowing how many of those people were actually guilty. Our ability to collect convincing evidence has drastically improved over the last century, of course guilty pleas have gone up.

I agree that there are perverse incentives, unfair treatment with respect to race and class, horrible prison conditions, too many custodial sentences for non-violent crimes, and numerous other issues that we should fix immediately.

>The Chinese camps are terrible in a different way, that doesn't excuse any of the inadequacies of the US prison system.

No it doesn’t. Are you reading the entire thread or are you just replying to my comment in a vacuum?
How does that not result in a net neutral investment return? Forgive my ignorance if this answer is obvious
> current discussions seem to suggest "Yes, this will go away" for "./services" being resolved to anything but an absolute location ending in "/services"

to be clear, this is still heavily in contention. node made a good choice to support requiring something without knowing exactly what type of thing it is, and a lot of people feel we shouldn't throw that away.
I'm not strongly opinionated or informed about this, so why does Node need file extensions when Other languages don't?

Is it because of non-JS imports? I know that when Ryan dahl announced Deno, he mentioned it as an obviously good change, but, I'm not sure what the problems with extension-less imports are.

(Edit for context: at work, we either use Closure or put everything under a global root, and only import JS, so maybe I've been shielded from the state of the world.)

Edit - Personal note - I know farmers who are disgusted that the industry now sprays crops with weed killer not only before the crops have produced food but also directly on the edible portions right before harvest as a means of drying the moisture out of the crops so they can be harvested before winter. Many elevators will not purchase the crops if the moisture content is to high.

It avoids reflow and is able to scale the content correctly as well across a large swath of devices and browsers.

The same is happening in software. Each new specialization carries with it heavy penalties in tooling and domain knowledge (bureaucracy and arbitrary details). This, in my opinion, slows problem solving as a whole and leads to the need for bigger teams when a more lean approach could have achieved more with less. It's bloat, but in people and tools instead of law and process.
I work/ed for companies that have a high percentage of Chinese employees. It was easier to learn Chinese than translate everything back and forth.
One that apparently took 15 minutes to write. If only I could derive a lifetime of income from 15 minutes worth of work.

Another interesting tidbit is that if it was a patent rather than a copyright, the rights would have expired 3 years ago. I spent far longer than 15 minutes just talking to the patent attorney the last time I filed a patent.
i suspect the leverage of pivoting the tri-spoke axle helps transfer more of the horizontal force you are applying, into a vertical force as it pivots. A larger wheel doesn't do this the same way
Yes. I guess the divvying up is more like breadth first. Most cases where I would use DFS this would work.
Larger wheel requires the axle to move up a larger vertical distance while being pulled up a step as compared to the compound wheel design
My understanding always was that the music industry even in it's heyday only ever allowed a very small number of extremely popular artists to make a real living, everybody else made mostly nothing. The share of wealth extracted by creatives seems to me to be going up while the share extracted by gate keepers is going down.

This can remain true even if the absolute size of the economy is still rising, so it can look like the rich are getting richer while the poor are also getting richer. Inequality is still rising, but the tide is lifting all boats.

Lisp isn't actually case insensitive. The reader is case-folding by default. You can set your READTABLE-CASE to change this: http://clhs.lisp.se/Body/26_glo_c.htm#case_sensitivity_mode

You're missing the point. This is the absolute ceiling of success that can be reached in Spotify. If the payout of that is 90k, what do you thing the payout of the typical artist is on Spotify?
In the end, the publishers have to exercise that control, by not putting all their eggs in one basket with a print house.

Most authors are so put off by the entire publication process that they won't be bothered by this, even if this takes some of the pain away (because now they'll have to put all their eggs in a basket that supports this approach). But as a few early adopters start realizing the advantages, companies like Penguin RandomHouse or more likely Amazon will acquire/start their own satellite JIT facilities to keep the cream from getting skimmed off their holiday booksales numbers, offering them as an included supplement to their existing print house system.

That doesn't help a bookshop's customers today when a troglodyte writes an out-of-stock bestseller and doesn't have the fortitude to call in the last minute specialist press. For some (thinking the latest fad diet books and political bestsellers in particular), they can wait.

The problem is the inverse. The problem is that there is not enough parallelism in hardware. Single digit core counts really are not that significantly parallel especially when there is a shared main memory bandwidth. An AVX2 code transform will give you more performance than a 8 core hyperthreaded code transform, without all the latency and coordination.
You guys are missing the point. It might be the all-time highest payout from Spotify. Because of Spotify, many many people will not buy the song. So what once would have been millions of dollars in revenue is much less, and the entire music industry is splitting a rapidly shrinking pie. Yea the very very top will still make enough money to live in big houses and drive big cars, but the middling people can't live off their take. So in order to make it you have to become an international sensation.
The multiple smaller wheels give an extra leverage point, whereas a single, larger wheel can require quite a bit of force. If climbing multiple stairs that can wear both you and the dolly out.

I'm not sure I would have preferred this back when I was still moving furniture for a living, as a furniture dolly with belts along the back/spine will slide up a flight of stairs without much trouble.
We are still at the experimental stage, so trial and error without clear theories is not unexpected. Chemistry formed out of alchemy: people fiddled and noticed the patterns. The patterns were written down and shared, and different people began floating theories/models to explain the patterns, and the theories were further vetted by more experiments.

Another thing is that the industry should look at other AI techniques besides neural nets (NN) or find compliments to NN's. Genetic algorithms and Factor Tables should also be explored as well. Just because recent advances have been in NN's does not necessarily mean that's where the future should lead. Factor tables may allow more "dissection" & analysis by those without advanced degrees, for example. Experts may set up the framework and outline, but others can study and tune specifics.

The article is unclear about which distribution channels her and her partners invested in to earn $60M in royalties since ‘94 before being “shafted” by Spotify for an effort-free return of $92k in a single day. Plus, Spotify did her a solid by making her the top song on the top Christmas playlist thus solidifying her position on the Christmas charts for years to come.
The goal is to have zero correlation to the index (called beta). You’re hoping that your long assets will go up in value regardless of what the index is doing (the alpha of the stock). Similarly with your short positions, you’re hoping that they are going to go down regardless of what the index is doing. In a sense you’re eliminating “chance” by driving the beta close to zero and instead are focusing more on what actually makes the company a good investment (it’s alpha)

My wife is a Chief Accounting Officer and she loves accounting. She lives and breathes it. She loves puzzling over accounting issues and over the years, I’ve seen her debug spreadsheets the way I debug code. In another life she would have been a tremendous programmer. Even though she is the highest accounting person in her company, she still has her nose in the books, always getting into fights against the auditors over esoteric FASB edicts (and always winning).

As a programmer, I love watching her work because it’s so similar to programming on a higher level.
Nothing heavy needed. You should know that your thing is working. A basic health check. You should know what errors are happening with basic logging. As soon as you have a paying user, you should have some form of reporting or alerting on this. You should have some basic metric(s) in place very early on like requests per second or sign ups. This should take you in the order of hours, not days, to set up. Nothing heavy. But without basic visibility into your system, you are asking for problems.

The idea that improving technology will make it impossible to 'leave your past behind' is a key plot point in the 1989 SF book 'The Boat of a Million Years' by Poul Anderson [0]

<spoiler>

The story concerns people who are effectively immortal barring death by massive injury. They don't age and often face ostracism or worse by superstitious or resentful neighbours / friends / children. They frequently (re)use the obvious solution - moving on and assuming a new identity - many times over 2000 years of different episodes. However, this becomes untenable and they eventually reveal their identity to a population that is itself becoming long-lived due to improved medical technology.

It's a great read and one of those that illustrates the fact that good SF writers can often write extremely good historical novels. Many of its historical episodes are superb interpretations of periods of history that nowadays aren't particularly well known., e.g. in the post-Roman near east.

Capitalization of proper nouns is a core semantic feature of English. While I'm sure you'll be tempted to hand-wave it away as a special case (see what I did there) of case-sensitivity, it nonetheless refutes your argument.

Pronounced “qiou,” the new character can’t be produced on a keyboard.

Question for anyone more knowledgeable on the topic: would reformatting text/Chinese characters/ language symbols in general as images prevent them from being detected and censored out as easily? For example, imagine a photo of two trees with a hammock in between them used to represent the letter “H.” A collection of images together would form words, presumably which are harder to decipher than just plain text.

I’d imagine that some machine learning techniques would quickly pick up the more obvious images, but anything more complex would end up requiring manual human review, which would then potentially overwhelm the ability of an actor to censor material. But I really have very little knowledge of how this works in practice.
