Fun fact: the shape of the propellant determines the thrust curve as it burns, as thrust is proportional to the surface area burning. And as material burns away, the surface area changes according to the pre-burn geometry.

MS completely redesigned their binary formats a few years ago. You're right about the current format, but the earlier one was completely undecipherable. Even the current XML has quirks in it to be compatible with the older format.
Makes you wonder what their response would be when I bring up that one of the more common games I play is Stormworks, where I spend most of my time in the engineering screen figuring out how to build fuel control and PID systems to run jet engines properly. Not quite to realistic levels, sure (it's one of my gripes about the game). But it's not on the level of mindless shooters by any means (which I also occasionally enjoy).

I recently started using Sapper for a personal site and have been enjoying it immensely. I find that the abstractions that Sapper/Svelte make in order to avoid full page loads, preload data, etc allow me to write the site in a component-oriented way while not shipping 5MB of JS to the browser. And, Sapper scales as the app gets bigger in a way that a raw static site just can't.

Rich seems to be advocating for a JS middle-ground here, which I think is a great direction to go in for this kind of workflow.

Scalable graph database with Scylla and JanusGraph
When I first started working with computer networks, I just thought of TCP/IP as "low-level stuff" and I focused instead on the higher level stuff. After I kept running into incomprehensible errors seemingly over and over again, I finally broke down and picked up a copy of Richard Steven's "TCP/IP Illustrated". Hands down, the best investment in time I've ever made. If you deal with distributed systems (hint, you do), you need to understand how they actually work.
Yup. AMD has an on-die 10gbe controller that would show up as AMD. Anything that says Intel/Broadcom/realtek/etc are off chip and something the MFG put on the motherboard which adds cost.
Ok... so drive when you drive to another city. Or even better, take a train.
I disagree with the article, I'd say writing your own CSV code is the second best option, behind not using CSV at all.

The reasons are:

- CSV is really simple. A complete RFC4180 parser shouldn't take more than 100 lines of readable code to implement. Even less so for the writer. So much that most of the code is likely to be interface code (file I/O, matching your internal data structures, etc...) rather than parsing. And chances are that a library won't even make your code shorter.

- As mentioned in the article, CSV is not well defined. I've seen all sorts of weirdness: semicolons vs colons, LF vs CRLF, simple vs double quotes, backslash escaping, comments, floating point numbers with comas instead of points. What your library understands as a CSV may not be the files you have to work with. I'd rather have a simple piece of code that correspond to what I am given rather than a big library that uses AI techniques to try to guess the intent of whatever wrote this file.

There are cases where it would be foolish not to use a library. I will never write a XML parser for instance, it is a well defined and complex format. JSON is borderline but I still won't write my own parser. CSV is essentially a proprietary format, so it is fitting to use a proprietary parser/writer.

I gotta say I'm surprised at the shallowness of the interpretations here. Very hasty stuff.

Her speech is very humanities academic and this being a casual interview she's not in a rush to lay it all out in one paragraph. She's claiming we haven't eliminated a number of possibilities about how brain structure works and how that transmits over generations. Concretely, (a) we don't know just how plastic the brain is and whether the brain someone has today has identical locations for behavioral responses to someone in the past across the board, (b) we don't know if cultural behavioral selection dictates brain structure transmission over generations; and (c) we don't know if behavioral control locations (what she's calling "modules") don't move over generations regardless of the questions about cultural selection:

>We know that ancient humans avoided predation, for instance. What exactly they did is something evolutionary psychologists have to show. Did our ancestors avoid predation because they were good at hiding in bushes or because they were running? Evolutionary psychologists would say that the better explanation is that they were running. But the fact that they ran to avoid predation and the fact that we have the disposition to run when we’re endangered still does not establish that there’s a singular module doing both of those jobs.

These are real questions because we know the brain is plastic and it's not a bone, so unlike paleontology they have no physical evidence to base their speculation on the past on.
This case is pretty irregular as far as rule of law goes. You just don't see executives imprisoned for corporate accounting shenanigans or trade with the wrong countries way down in their reporting chain. The laws are long and can capture anyone, why was this one brought to bear in particular, at this particular time?

I suspect we have very different opinions on how frequently police lie on the stand.
Even if the code isn't public... it still exists. And since we are talking about "does their exist any possible program it can't determine", we know that some sequence of bytes will be that program, and therefore it is possible to exist.
Just because all kinds of inputs exist, doesn't mean you should support handling them all.

YC Startup's AI Sensors Are Getting People Safely Back to Work
There's a pretty interesting part about how Chinese media describes the causes of the unrest in Hong Kong that gives a window into how they think about the world and human nature. That is, the point about how Hong Kong's unrest is due to its education system that gets raised.

Right now, 1 country 2 systems means that PRC can't just dismantle HK's education system and institute their own until 2047. But the comments HK's education system indicate that the PRC thinks if they could just put HK's children through a state-approved education system, in 1-2 generations all the unrest in HK would be over. This is a worldview that people are ultimately malleable, or at least their children are, and that with the right childhood education you can get people to believe anything. Brainwashing, after all, is originally a word from Chinese that became an English loanword. In this worldview, everyone who's gone through schooling is brainwashed in some way to support the state that created the education system. And this worldview applies to any state-sponsored education system in the world. Take a Chinese immigrant family in America, put their 2nd gen kids through the American education system, by the 3rd gen you have Americans that can't imagine themselves as anything other than Americans.

This worldview that people can be molded is probably why China is in no rush to exercise full control over HK and Taiwan. After all, if people's national identities are so easily changed, any discontent in HK and Taiwan today can be brainwashed away in few generations. It's far more important to focus on the physical and economic levers that would allow China to exercise long-term control over those regions than social levers that determine whether people in those regions actually like the prospect. If they don't like it, their children will.
> your 10k npm dependencies

Svelte projects do not put 10k dependencies in the final bundle.

In fact when using Svelte you won't need many dependencies you typically need when using React:

- State management (MobX, Redux, etc)

- CSS stuff (classnames, CSS in JS, etc)

- Animation

Even on a simple use case like a synthetic benchmark Svelte is still the absolute leader in start-up metrics:

Actually Animal Crossing removes the element of failure deliberately to provide a soothing, un-stressful experience. There isn’t even a counter for how many bugs and fishes you still could catch in the current season. There was a thread recently here about the associated genre Iyashikei. The success of this game should be quite interesting for video game makers who traditionally address and compete for a very narrow market.

How many pedestrians do you typically see on the highways between cities?

I'm talking strictly about streets inside cities. Cars are great tools for traveling great distances. They're a ridiculous tool for traveling inside cities. They should be looked at with a similar level of absurdity as taking a cruise ship out on the lake for a weekend fishing trip.

It's a very American attitude that this is "cute" or "idealistic". In cities like Copenhagen and Amsterdam, bicycles dominate intra-city transportation. And what's funny about these cities is that they have worse cycling weather than most US cities.
My understanding is that the lines don't have the signalling infrastructure required to run trains that close together.

Half-OT:

Currently I'm playing Stardew Valley on my FireHD10, I never played a mobile port that had THAT good controls.

I also got Terraria and Minecraft and they are pretty bad to play with awkward on-screen controls.

Does anyone here know of games that have good mobile ports? Or even good mobile games to start with? Most "native" mobile games just were really basic, full of in-app purchases etc. so I was looking more into ports, but if you know something good, let me know :D
Web apps are:

* platform agnostic

* can't be blocked by a central platform gate-keeper

* generally much smaller (download size) than native apps

* don't take up permanent space on your device (good for things you only use occasionally)

* always up-to-date

Personally I prefer native apps for tools I use frequently. Everything else I prefer the web.

I have one of these, got it after landing my first big tech job. I learned to program on an emulator of these 8-bit computers so it meant a lot to finally get a real one.

Most people search for high level languages when learning programming. My brain worked different - I wanted to boil the complexity away and learn the fundamentals. These 8 bit machines were the simplest computers I could find to achieve that.

The joke was on me though, mine had been upgraded to a Z80 card (yay!) that unfortunately no longer worked with the front panel (boo!).

The lateral componant was to pull the capsule out of the flightpath of the rocket. The total accleration of the tower+capsule was miniscule compared to the rocket overall. If it didn't move left/right a bit then the rocket would easily catch up.

The thinking at the time was that, without the capsule attached, the tower might not fly as planned. It could be unstable in the thin up atmosphere. It might spin. That lateral thrust, withough the mass of the capsule, might cause it to spiral, leaving it floating out in front of the accelerating rocket.
>In 1990s when the Philippines grounded an old navy ship on Scarborough Shoal in the south China sea to reinforce their claims, there was barely a peep from China

They engaged in combat with both Vietnam and the Philippines over islands in the 80-90's, and effectively took over Mischief Reef in 94 by building bases on an island. Not to mention what was a huge victory for them in the return of Hong Kong. That was their primary aim for much of those decades.

There probably is some growth in aggression, but nothing like "Xi's waiting for an election before invasion."

My wife has also been seeing an increase in strategic defaults. These are cases where the company could easily make its loan payments, could in fact pay off the loan entirely with the cash it has in the bank - but chooses not to. The court systems are overloaded and oftentimes closed right now, the lawyers all have to work over Zoom, so what's the lender gonna do? The company views it as more important to hold cash in the bank right now than to service existing loan obligations that its creditors can't enforce anyway.

The entrepreneur in me is saying that the biggest start-up opportunity in America right now is a government. We're on the verge of a cascading failure in the legal and political system, and few people realize how much of civilization rests on having a functioning legal system.

That behavior is technically correct because those are all valid representations of that value, e.g., 007449938 = 7449938 = 7.449938E6. Pretty much any plain text (or binary) data format will have this same issue, unless it supports additional metadata for display purposes.

I think the sticking point is that this method of acquiring money is only available to those who are already have more money than any one person could ever spend, and the money that is acquired often comes from those who do not have enough money to retire yet, via institutional investors that manage insurance, pensions, and retirement accounts.

That is, people who could retire now and live without worry for the next thousand years or more are taking more money from people who are toiling away to try to retire by age 70, and making it more difficult to accomplish that goal.
