A .30-06 round, aimed high, with the goal of getting it as far as possible, is generally going to max out at 1.5-1.7 miles, assuming favorable winds and no obstacles.

For most practical shooting, at a target that's roughly chest level, ranges aren't going to exceed ~500 yards, and are often a moot point with a decent backstop.

From wikipedia: "The acre is related to the square mile, with 640 acres making up one square mile. One mile is 5280 feet (1760 yards)"
Very good point, thanks. I had that as an implicit assumption.
AI sound/ cough classifier as Covid19 early warning system?
Business owners considering re-opening their business are confronted with two very serious dilemmas:

1. How to ensure a safe working environment for their team & clients without compromising convenience or privacy? AND
2. How to set up an early warning system to manage the risk should an infection happen in the team?

PCR tests are obviously not an option. Immunity registries are potentially interesting, but unrealistic. Besides, there is no evidence that antibodies will avoid a new infection or transmission.

I have been thinking a lot about acoustic surveillance. Basically, using an app on employees/ residents phones, or installing dedicated devices around the premises, that run an AI acoustic classifier that can identify coughs & sneezes.

At any given point in time, there is a spectrum of "normal" frequency of coughing/ sneezing in any given location. Sound monitoring happens in real time, which means that any deviation from the benchmark will be immediately obvious and owners can react quickly by isolating risk areas, quarantines, tests and so on as needed.

This can be done at the level of a campus/ facility, but also at municipal/ community levels.

What does everyone think? Feasable?
I don't know. But in any case, it's not just the fuel.

Have you seen the proposed Moon-Starship? They'd require some quite impressive crane to even get cargo into the ship.

Additionally, there's the problem of the landing site. It's considerably more difficult to land a rocket on unprepared, rocky terrain than on a carefully prepared landing pad. Plus a suitable area has to be found first, too.

There's simply no guarantee the first Starship(s) even make it to the surface in one piece, let alone ready for refuelling and launch.
Sure buddy.

The F-1 rocket engine on the first stage of the Saturn V used a similar arrangement, with the fuel also doing double duty as hydraulic fluid, coolant and lubricant.

Unionization, as argued for in the op-ed, is something that’s legal right now. We just need government to enforce the laws already in place. Laws paid for with the blood of the labor movement in the early 20th century. Unfortunately regulatory capture has eviscerated the agencies and government bodies tasked with upholding those laws.

QuestDB is open source and will remain so forever. You will be able to scale with it. Our commercial product, Pulsar, uses QuestDB as a library and will offer enterprise integration and monitoring features, which are typically required for massive enterprise deployment.

To answer your question, it will depend how big of a scale we are looking into. If you are a large company running questdb throughout the organization and need a specific feature set to do so, you will probably be looking to get our paid offering.

A version 0.142.2 is perfectly possible with Semver, it just implies that the the developer has had a lot of iterations on the idea, but never got to the point that they consider stable.

If the software had a stable API at that point, but they were still using a 0.x.y version number, then they wouldn't be using Semver properly, since 0.x.y versions are for unstable initial development releases.

> Why would you obtain your perspective from a click-driven Vice article referring to a study of 73 people instead of the infinitely more robust source of truth?

My perspective doesn't come from the article, I merely put it there as it gives a readable summary to the otherwise terse scientific papers.

Regarding the particular study, that study has tons of citations to other studies and meta studies, a good chunk of which complains about *adverse effects are not sufficiently mentioned", which I'm doing here. I'm not claiming that the score is settled on this matter, but the fact that there is no talk on adverse affects deserves attention.

> Second, breathing has multi-thousand year old legacy spanning multiple cultures and eras touting it's benefits

So does psychedelic mushrooms or circumcision. The good thing about science is we can systemically study traditional practices instead of taking their word for it. I don't think tradition is an infinitely robust source of truth, especially in comparison to scientific knowledge. Nonetheless, I value traditional knowledge too, but you can't claim traditional information and its context have propagated to our day sufficiently well (e.g. is circumcision a rite-of-passage anymore?), including the knowledge/caution on what to do with adverse reactions.

I'm sympathetic to this view and it was probably true in older generations of chips, but it turns out that instruction decode is a very small portion of die size and power usage these days.

It's worth pointing out that modified gravity has less acceptance than even string theory. It's worth working on, as a somewhat plausible alternative to the standard theory, but it's not very likely to end up being correct. It's worth ruling out fully, though (the same can't be said of e.g. flat Earthism).

This particular work seems like adding on epicycles, or overfitting as you'd call it in machine learning.

Actually, if they spend more than two hours, the question is why. We are happy to see them get interested in the task and dive deeper, but we just don't want to ask for more, that would be unreasonable in our view. It's fine if the code is broken, or has a couple of bugs. (It's best if it compiles though!)

The goal is as much to learn how they think, solve problems and communicate as it is whether they know how to write software.

I'll give one example: One task is to figure out how long it takes to grab the current time from the operating system. We use a rather obscure OS. A candidate chose this and solved it simply (though it's got a couple of points to mind), but then he got curious and wanted to know whether a virtual machine had a different timing and then what the performance on a different operating system was. He told us that he spent about 8 hours altogether. I felt a bit bad on one hand, but on the other, it's exactly what we like to see: Solid programmers who love programming technology for its own sake.

"most recent" is min(time) where time>=$my_datetime ;

I don't understand your query - max(time) .. GROUP BY time means that every record is its own group, so max(time)==time; also, you will have a result for every single point in time after the requested time.

There is no way in standard SQL (without window extensions) to do this with just one clause; you need the price associated with the min(time) associated with time>=$my_datetime ; You need either a subquery, a join, or some other correlated query. e.g.

SELECT time, price FROM trades WHERE time IN (SELECT min(time) FROM trades WHERE time>=$my_datetime)

And that's for one record; It gets more complicated when you try to do a batch.

Maybe I missed it, but I didn't see if this was done before or after the pandemic lockdowns started. I've got a hypothesis that the Twitter (etc.) mobs are getting worse precisely because of the lockdowns.

Locked down, with very little to do, people are desperate to feel like they're doing something useful. Joining in an online mob feels useful. It makes a person feel like they're doing good in the world. It gives them the rush of accomplishing something. It's an illusion, but there's a lot of feedback (upvotes, faves, retweets, etc.) that makes it feel real to people.

I don't have any great ideas for how to improve it. I've been asking myself "will this actually do any material good?" before engaging, and I significantly cut back on social media. But good luck convincing everyone else to do that, too.
> (16 total slices, 400in², 25in² per slice)

I think you did the math wrong?

Area is pi x r^2, which for a 16" pizza would be pi x 8^2 = pi x 64, which is right about 200in^2

A few of the pizza places around here offer 20" pizzas, which would be pi x 10^2, or pi x 100 = 314in^2, which is actually big enough to feed a couple people.

That said, whenever I read "two-pizza team" (a term I've never heard before), I assume that means 4-5 people at most.
Because our "pizza" is like three of your pizzas.

We have both elements. The code they wrote is subsequently reviewed live with 3 or more of our engineers and all of these aspects are explored.

I think what gives our approach balance is that we are also committing to making a time investment. Reviews typically last an hour, which means that the 2 hours we ask from the candidate is matched with 3-5 hours of our engineers' time to review and discuss with them.

Plus:

Brilliant’s computer science courses cover slightly more than my actual software engineering degree from Aberystwyth university, and their maths courses cover more than I did at A-level.

The various introductions to matrices (in different contexts each time), are better than the introduction I had in my A-levels (with a good teacher!), and I would say they are of comparable goodness to 3blue1brown. Only, all of it is that good.

If you get stuck because a topic assumes knowledge you don’t yet have, they have a course to teach you what you need to learn.

I can’t comment on the levels of Brilliant’s physics, chemistry, or biology as I have only GCSEs in those subjects — but I can say they’re well-described and engaging.
