getting raw materials from space onto the surface of earth intact is such an easy problem that dumb rocks do it literally every day entirely by accident. you just need a low enough sectional density that it loses most of its kinetic energy to the atmosphere rather than exploding when it hits the ground (i.e., not much higher than 1kg/cm²), a high enough sectional density that it doesn't burn up entirely given whatever materials are on the front side of it, a shape that's aerodynamically stable in the supersonic regime, aerodynamics and structural integrity such that what doesn't ablate lands in one piece rather than exploding into a fireball, and good enough targeting that it lands on land in friendly territory rather than at the bottom of the ocean

i mean i'm not an expert in the area, but i think this is a well-understood set of problems. passive reentry vehicles have been used for decades for spy satellite film canisters, v-2 ballistic missiles, scud ballistic missiles, icbms, mirvs, and space capsules like those used in the vostok, apollo, and mercury programs. it gets easier in this case because you don't care if it breaks when it hits the ground, so you don't need parachutes or retrorockets; you just don't want it to vaporize

specifically, a hunk of mass at rest at the von kármán line of 100 km has 981 kilojoules per kilogram of gravitational potential energy with respect to the ground. one degree of temperature is roughly one kilojoule per kilogram, so that's roughly 981 degrees of heating if it falls to the ground from that height with no further air resistance—not enough to melt steel, nickel, gold, platinum, or even mafic rocks. and it's still 981 kilojules per kilogram whether it's a kilogram of platinum or a thousand tons of platinum. but it gets better! that heating is shared between the reentry vehicle and a somewhat larger mass of whatever it hits, roughly in inverse proportion to their stiffness. and of course there is atmospheric resistance, even without a parachute—quite a significant amount of it at the comparatively low sectional densities you need to lose most of your escape velocity from hitting the atmosphere. so, typically, when meteorites land, they aren't even hot. the arguments above explain why in most cases they can't be hot unless they hit so hard as to blow open a crater

980 kilojoules per kilogram is 1400 meters per second, about mach 4, so you really don't want it to hit you. but it won't even melt, and newton's penetration depth approximation assures you it won't penetrate very far into the ground, like, less than a meter

so basically you're worried about a nonproblem

I’m building a calmer way to produce and consume content.

Microwaves seem to prefer syrupy foods because syrup typically has a high sugar and water content. Both sugar and water molecules are efficient at absorbing microwave energy, so they heat up quickly. This is why syrupy parts of a dish often get much hotter than other parts when microwaved.

https://RTCode.io

We're continuing to develop and refine our core offerings at Elefunc:

RTCode.io is our real-time web development playground for HTML, CSS, and JS. It provides instant feedback - as you code, you see the results immediately. A key feature is our support for in-editor Workers, allowing developers to write and test backend code directly in the playground.

These Workers integrate seamlessly with RTEdge.net, our global, multi-cloud edge network. RTEdge.net offers distributed hosting with auto-scaling capabilities, giving developers a powerful platform to deploy and scale their applications worldwide.

We're also running rt.ht, which we tout as the world's shortest SaaS eTLD.

Our focus remains on providing developers with robust tools for real-time web development and edge computing. We're always looking to improve the integration between RTCode.io and RTEdge.net to streamline the development and deployment process.

If you're interested in real-time web technologies or edge computing, we'd love to hear your thoughts or answer any questions about our platform.
It's just first PRC AAA game. It's pretty good or rather not bad. Curious Chinese consumers (of which there are many) voting with their wallets because they want more. Helps that it's based on significant literary canon, think LOTR + harry potter + Shakespeare with 500 years of cultural presence. Total War Three Kingdoms also sold well due to PRC consumers, an indigenous production just gets even more attention. I think the game is pretty mid like most assassin's creed games but I like the environment design and how production scanned a lot of temples.

If your memory is paged out and you then access it, using your definition, it would block.

So, in the context of async code, there's no difference from the application perspective between reading mmap'ed data and reading "regular" data (ie memory from the regular paged pool), as both could incur blocking IO.

If you're lucky and the mmap'ed data is in the system cache, then reading that data will not block and is fast. If you're unlucky and your process has been swapped out, then doing a regular memory read will block and is slow.
Twitter doesn't encrypt messages, so there is indeed no chance of that happening - after all the reasoning for this arrest is fundamentally inapplicable to Twitter.

It's however a very very very slippery slope to prosecute someone for providing the tools to hold encrypted communication, just because this is also used by criminals. A lot of privacy oriented services would probably have to exit France if this holds up

I'm working on a side project which is a Python library that provides of an abstraction layer to manage infrastructure in cloud providers by interacting with their APIs. This is something I've been developing every now and then for the last months after years of working with Terraform and getting tired of the limitations of it's DSL (yeah, Pullumi is better but I just simply want a generic library with classes representing services in the cloud I can call natively in Python without having to deal with a 3rd party application like Pullumi is!).
Lately I have been working on making MicroPython an excellent platform for deploying Machine Learning on microcontroller-based sensors. Primarily this is via this open source project:

I am currently working on a custom markup language called atex. It's syntax reminds of latex syntax, but with @ instead \ as a special character (very similar to the Lout language, if anyone remembers it). Also, the atex language hasn't any predefined commands. Instead, all commands are defined via schema specified in a separate YAML file. Schema defines commands that can be used and means of "rendering" those commands to different targets (HTML, Tex, Typst, whatever...)

Just today, I finished first working version of the new compiler (https://github.com/ubavic/mint). It is written in Go, and there are lot of things on the TODO list, but it works :)

This is actually the second compiler for the atex. The first one was written in Haskell and compiled fixed document schema. I used it for writing a book on Haskell (https://github.com/ubavic/programming-in-haskell).

That's the problem of the generic establishment's dominant principle: there's a pedagogic influence where a trend towards aggressive responses to criticisms of popular science is valuable and, really, should be expected. Capital rewards and incentives go to the distributed liberal justice warriors when they implement regurgitations of trite and irrelevant talking points. Like an objective optimizing GPT-4 model that focuses on “no true X” meme tokens. Civilization's trained citizens miss details that matter, as they're limited to the compliant programming script they must follow and never deviate from.

Besides violating some sacred cow and norms, how does the "no true Scotsman" fallacy proposal relate to the fact that no true scientist would ever consider the Boeing aerospace company or Elon Musk anything close to engineering geniuses? Because, otherwise, you're just avoiding the objective commentary's point and discussion it leads to. Whether this evasion is intentional or not.

Just sit and watch, while not doing anything else? Die Hard. At least once a year since it came out in 1988. Die Hard and pizza have been a Christmas Day tradition since it came out on VHS in 1989. (I saw it in the theater in 1988.)

Otherwise, if I am watching a movie more than once, it's wile I am doing something else. Working from home, I often have old science fiction B-movies -- both the MST3K versions and unriffed versions -- running in the background. Others I'll "watch" while doing something else are Animal House, Blues Brothers, the Lethal Weapon films, Patton, James Bond, and some others.

I’m a tech nerd rare coin & currency dealer! I took my two hobbies and combined them into a real business and I’m having the time of my life. Just launched a proper retail site here:

https://www.rarity7.com/

About 50% of my days are spend doing the coin dealer stuff - hunting for inventory, buying collections/doing appraisals, going to coin shows and buying and selling in person, etc.

The other 50% I’m writing code and building out the tech stack for this business. I’ve written the whole backend for the retail site myself, which includes my own inventory management system, sync with eBay and other marketplaces, etc.

I’ve also built out a research tool which includes an ML price prediction engine engine (which sounds fancy but is really just a tabular regression model).

Backend is written in Crystal because I love the language and there’s nobody stopping me from using it :) Frontend is all Svelte and they’re glued together using a mini framework I wrote:

https://github.com/noahlh/celestite

I probably have 5 years worth of ideas I still want to build and I wish I could spend even more time building it all, but it’s super fun actually using it in the real live marketplace so I’d never give that up.

>"legally, no one has ever decided whether a journey into space technically counts as leaving the United States."

That gave me a good laugh. Shouldn't it definitely count? You're zipping over every country on earth while you're in orbit so you definitely left!

But if you take off and land in the US, did you _really_ leave? You don't go through customs and immigration for every country you fly over when you're in an airplane, and generally aren't legally considered to have "visited" them. So, wow, good question.
Not quite true for Dulles. You're looking at 3 hours in good traffic, and it's not a relaxing drive. BWI could be done in 2.5 hours and you don't have to deal with the two way road from Frederick to Leesburg.

So, what happens if it does blow up, or otherwise has a catastrophic failure on re-entry? Will we be able to say for certain if it was due to Starliner’s faults, or just the fact that there wasn’t a human pilot?
