Skymapper.io: A Decentralized Network for Astronomical Observation, Data Sharing
Payments for making past discoveries public create terrible incentives. They encourage you to keep your discoveries secret until someone is willing to pay enough for them. If your discovery is not particularly valuable on its own, but someone else could make a breakthrough building on it, that breakthrough won't happen, because the other person does not know about your result.

Patents, while also terrible, are a better model. They at least require you to disclose the invention first, and then it's up to you if you can take advantage of your temporary monopoly. While practical impact may be lagging due to reduced commercial interested during the monopoly, the result is at least public, and other people can build on it.
What is your plan in case a ship-sized fusion power plant turns out to be impossible, for example if you build one on land and much bigger and much heavier than your target on sea and it just doesn't work, or if you find out before you build it that it won't work, for example when you are running simulations on your design?
I want to be able to buy and sell cars as easy as trading Pokemon cards. There's lots of issues around fraud, scams, and trust in the car industry. So I've been working on building an online car escrow service I'm calling Carma Pay that de-risks buying or selling cars, while making it faster and a better experience.

I'm also a student at WSU and will be pitching at our business plan competition.

I think brew's author point holds even if you replace "invert binary tree" with any other LC problem.

In terms of the problem itself, a binary tree can be expressed something like:

type Node<T> = { value: T, left?: Node<T>, right?: Node<T> }

Given a root, you can invert it recursively with some code like this:

function invertTree(root) {
if (!root) return null;

// Swap!
const tmp = root.left;
root.left = invertTree(root.right);
root.right = invertTree(tmp);

return root;
};

Or using an explicit stack:

function invertTree(root) {
const stack = [root];
while (stack.length > 0) {
const node = stack.pop(); if (!node) continue;

// Swap!
const tmp = node.right;
node.right = node.left;
node.left = tmp;

stack.push(node.left);
stack.push(node.right);
}
return root;
}

I think without prep would be harder to come up with the non-recursive version.
Back of the envelope (and some quick googling), a large container ship burns hundreds of tons of fuel per day, at a cost of 700-1000 $/t. Plus, all that fuel occupies tonnage that isn't carrying paying cargo. If you can save on that with a magic new reactor, the cost of a well trained tech on every ship isn't going to break the budget.

Wouldn't the FCC come into play at a later level? We're talking about providing source code to device developers, not end users. As long as the device developers ensure the products they release are locked down, the FCC shouldn't care about it - they only look at the final product as sold to end users.

I'm not worried about matching the build script language to the project language.

I am worried when I have to install a full dependency graph to run your build scripts...that's where things become brittle and annoying.

Python with Typer[0] and Plumbum[1] is great for quickly cranking out ergonomic build scripts, or Invoke[3] which is intended for exactly this purpose.

[0] https://typer.tiangolo.com/
[1] https://plumbum.readthedocs.io/en/latest/
[3] https://www.pyinvoke.org/

But then I've gone from "any Python 3.x can be used as-is" to "setup a Python venv and install these dependencies" as soon as I add any dependency :(

So you either have to constrain yourself to Argparse and Subprocess in the Python stdlib, or accept that your build scripts are a project unto themselves.

This applies similarly to Ruby, TS/JS/Node, Perl, etc.

We made a better Apple Intelligence from Africa Kenya, budget less than $50
We have made an even better platform to create and edit images through a simple chat interface.

Actually, Just a few days ago, I was almost giving up trying to create an easy way for you to upload your photos and get the edits you want through a chat. But somehow, I really can't explain how everything fall in place, we pulled off something amazing.

On Our tests on things like background replacement, object removal, adding things to the image, change properties of objects in the image like color and more, we have found that our edits are way better than what apple have to offer at the moment.

Now no one needs high end phones to try out cutting edge features. they can access it right now from their browsers.

Now here is the kicker. We are a team of 1 with a budget of less than 50 dollars, from Africa, Kenya. And managed to pull of something of this magnitude. It has been a mind-blowing journey for me and I would like to share it with all of you.

I mean X is a private company. Elon can run it however he wants and is free to push the website as far to the political right as he wants. Complaining that X is being political isn't going to change that.

Likewise the Canadian supreme court has no obligation to publish on a privately owned news site that contains, in your own words, a "concerning level of politicization"
I prefer to have a “scripts” directory with each script being a separate executable, maybe a comment on top of each script. Discoverability is just looking at the file system with any tool you’re used to.

Both Bash and Python are a given anywhere. I use Bash for simple stuff and Python for the complex stuff. Thanks to each script being a separate file, I can mix Bash and Python, but using only Python is very valid.
Yeah, but he apparently decided (and correctly so, IMO) that this explanation was long-winded enough without that added long-winded sub-explanation.
Given his skills, he'll be able to pass the usual coding interviews with some preparation. In most companies, the bar isn't that high, they're just there to ensure that candidates have some minimal (usually undergraduate) algorithmic knowledge, and is able to interact with the interviewer (communicate their ideas, act on hints and so on...).
Wikipedia's list of islands (https://en.wikipedia.org/wiki/List_of_islands_by_area) starts with a separate table for "continental landmasses", containing Afro-Eurasia, the Americas, Antarctica, and Australia. Australia is ~3.5 times the size of Greenland (the #5 landmass) so between Australia and Greenland seems a nice place to draw the lint.

But Greenland is in turn ~2.5 times the size of #6 New Guinea. Maybe if Greenland were more populated (let's imagine, say, that the Earth's axis is positioned differently so that it's warmer there) it would be considered a continent?
It is not completely unexpected. Within executive ranks there is an odd FOMO on 'new big thing'. That's partially why you saw attempts to sell more passing fads like crypto-everything, blockchain-everything, iot everything, subscription everything. It is easy to make fun (especially in retrospect), but being wrong means executive may make the mistake that Dwight made and declare internet a fad.

It’s naive to assume miners will not sufficiently coordinate to stop Bitcoin becoming worthless. They are all economically incentivised to keep the network continuing to function.
You're being facetious and I can get my fill of that on reddit. You're still making voluntary choices when it comes to both Google and, especially, Amazon and Alexa. But what you (and I, and most people) want is the convenience, even if using "big tech" is less appealing. That's not ownership, that's a choice, a service bought and paid for – unless we're talking about a meta sense of ownership where you've convinced yourself you've been owned and have no alternatives.

For you maybe. Why it makes sense ? Are Xcode developers not able to test their code ? Does Apple need to know who you talk to, what are you writing or what did you eat ?
The best advice I've heard about keeping a notebook or journal is "Don't overthink it, just use it."

Mix your ideas, data, todos, and everything else all together. By nature of a notebook being composed of successive pages, your notes will be naturally organized by time through append-only operations.

You'll find your important stuff by folding down the page corner, frequently flipping through it, or adding bookmarks/sticky notes; no index required.

Anything more is getting sucked into the analog version of writing your own blogging engine/static site generator.
They could fix typeof to make it something useful. Like the ability to take the type of something and pass it around.

And add slice and buffer typedefs to the standard library. Especially since they added counted_by to the language.

Add a way to define a slice the points to a c string.

Are you trolling or what. Let's see what's written in the comment above.

> If A reduces to B, it means that an algorithm implementing B can be used (with some pre- and post-processing) to solve A.

Here we say that that we can solve a "hard problem" if we can express it in terms of the "Document Ranking" problem.

Let's rewrite that quoted sentence:

An algorithm implementing "Document Ranking" can be used (with some pre- and post-processing) to solve "Hard problem".

Let's do substitution in the first part of the sentence, "If A reduces to B", where A is "hard problem" and B is "Document Ranking":

Hard problem reduces to Document Ranking.

That means EXACTLY that we can USE Document Ranking to SOLVE the Hard Problem. Just as we wanted.

I mean, I've read enough of the Bible to know it's pretty out there. It's packed with the writings of humans who lived in a time so different to now, with interpreted translations. Shakespeare's writings are a lot more relevant to us, although maybe inspirational rather than aspirational, and far better written. A modern take with updated aspirations that is understandable and approachable isn't a bad thing to equate it to, even if it's the basis for an entertainment.

SQL Injection and XSS are actually great examples of vuln classes where the winning strategy is safe APIs rather than diligent sanitization. "Just sanitize all your user inputs" is hard to do correctly because it is difficult to create automatic rules that detect every single possible violation.

This reminds me of something that has been bugging me for quite a while - are there some extensions/services that would do video translation ?

What I mean is that you have a video with text in it in a foreign language (labels on stuff, signboards, even hardcoded subtitles) in a foreign language & the tool would translate those to a language you can read (like English) in place.

While I'm aware of all the various edge cases and challenges for this, its not a theoretically thing - I can already pause the video & use Google translate on my phone via the camera feature to translate whats on the TV/monitor quite well.

I would just want something a bit more integrated so that I don't need to fumble with my phone every time I want to translate something on the screen. :P

Even automated still frame translation would be enough - just pause the video & the tool would analyze the still frame & translate any text it can find in place.

Like, this is evidently possible nowadays, but I have yet to see it implemented in in an integrated manner so far.
That's a highly biased opinion. The Newtonian conception of physics is trivial for us, and we can say that most people could come up with the ideas by their own, but that's because our world conception is based on those ideas; it's already implicit in how we understand the world. That's why Newton was so important, there was a shift in the whole conceptualization of the physical world. With Maxwell's equations is similar. The interpretation as waves, the fact that the equations are Lorentz symmetric but no Newton symmetric, etc. All that is free for us, and it is not obvious at all.

How to Solve Problems
Git-truck is running in a web interface, even though it’s self hosted. But rendering all repos definitely sounds interesting. I had an idea to create a repo, which would basically be a monorepo, where i would register other repositories as submodules. Sadly git-truck does not seem to like that.
Let's be realistic, it would have a diesel engine as a plan B.

But if you like sails: my pet hypothetical technology is wind-driven hydrogen tankers (or tankers for some other e-fuel derived from hydrogen) that sail out empty, then cruise around wherever there is plenty of wind. They'd have a turbine/generator setup driven by the water passing by and use the energy harvested there for filling the tank. Cruise around as long as it takes to nearly fill the tank then return to port (and fill the rest on the way back). There's a lot of oceans where systems like that could cruise around on. (same concept could also be used for desalonation, there it would not only be about energy but also about avoiding local brine concentrations)

What billionaires mean by "personal liberty" usually is, though.
it's an attack on the managerial class that absolutely deserves to have their funding cut. If you attended university in the US since the turn of the century you would have been party to the dearth of resources dedicated to actual education, especially in comparison to lavish facilities and a bloated administrative staff that, at least in my experience, did nothing except waste money and create policies that actively harmed the pursuit of knowledge

With the amount tuition costs today, it is absolutely embarrassing to see an organization like Stanford complaining about losing subsidies. Subsidies to rich organizations like this are downright regressive.

Thinking of social anarchists. Extremely "left" in many regards by North American standards, and pushing towards being about as pro personal liberty as you can get.

Arguably social anarchists have a different read on what personal liberty is and should be compared to, say, Ayn Rand. It might not be the best comparison, but I think the gist of it is true. Heaps of leftists value personal liberty.
