Everything old is new. I don't think anyone predicted that the future (our now) would be consisted of massively scaled timesharing systems, hehe.
Why not use the multiprocessing module? (if you can partition your problem space). I find memory sharing much more difficult to reliably implement an algorithm, and speed gain might be lower through cache conflicts.
Its not only about being less emotionally supportive or anything like that. Many kids sport is simply considered fun there is no huge competitivity and no need for constant parental supervision either.
>How much power does a solar panel produce that’s not facing the Sun?

Nothing.

>But yeah, maybe an external little solar array would be more flexible.

And those little solar mats are mediocre at best. They just don't work very well. They take forever to charge and require strong direct sunlight. But hey, if you want to use them, go ahead. They are still better than having them built into the device.

> Most physical objects do not have naturally harmonic vibration spectra.

What is your basis for saying this?

A large number of physical objects, solids as well as hollow can be approximated as systems of springs, surfaces and tensile elements, which all have some frequency response. It isn't rare at all for a physical system to have a very sharp resonant peak in its frequency response, to the point that you'll often find mechanisms to dampen that response so the structure will survive certain inputs.

Recent versions of Python (3.8+) have introduced a SharedMemory class for sharing memory between different processes (see https://docs.python.org/3/library/multiprocessing.shared_mem...).

The implementation may still be a bit buggy though, so use with caution! https://bugs.python.org/issue38119
The first item in the list reminded me of an exploit on Windows 7 that allowed anyone to login and use the computer without an account. I don't believe it treated you as an administrator, but some other system user instead.

The trick was:

1. On the login screen, press the shift key until the Sticky Keys window pops up.

2. Click the informational "learn more" link. That will open up a text file in Notepad.

3. In Notepad, select File > Open.

4. Navigate to system32 and rename the sticky keys executable to something else. Then, copy bat.exe and give the copy the name of the original sticky keys program.

5. Press shift multiple times like before, but this time a terminal will appear.

6. Run explorer.exe

I was amazed that this not only worked, but wasn't patched in the years that I used Windows 7. It came in handy a few times, but I do hope they've fixed it by now. I know a lot of people still use Windows 7.
A little video editing would be nice.

It's almost like NASA doesn't realize many people watch these videos.

I like watching behind the sceen stuff, but I also want NASA to come off in the best light.

The video had a production value of a subpar PBS late night video.

NASA has a duty to promote the agency too. There's a PR value to everything, especially when using public money.

(I want to give NASA more funds some days. Other days, I would rather give it to Musk. I'm not sure anymore who will use the money better.)
Transflective displays do seem to result in decent battery life, the Pebble Time watch is a good example. Though we do now have long lasting OLED watches – looks like running Android on a beefy CPU vs a tiny RTOS on a microcontroller is the bigger difference… buuuut still the Pebble gets away with a smaller battery than these OLED ones I think?

I don't have a concrete answer, but the X-Plane flight simulator also simulates the Mars environment (see [1]) and aircraft aerodynamics are also properly simulated, so it should be possible to build a "physically correct" Mars helicopter and find out.

Here's that one weird tip that you were looking for all your life but didn't realize it: pretend the front part of the piano keyboard isn't there, and just look at the part closest to the fingerboard. Presto: chromatic keyboard.
It may have something to do with the fact that Mars' atmosphere is very, very thin (I think they mentioned it's 1% density of Earth's), so there are much fewer particles hitting the ground and pushing the dust, compared to e.g. a small hobby drone taking off here on Earth.

I'm sure there was some dust thrown up in the air, but probably not enough to be seen against the background.

The conclusion is they are not, so I guess it's good someone did the study then [7]

I'm not sure there's any real purpose to doing this since proper machines can record it. Unlike earthquakes for instance were local data might be useful.

Using the magnetometers for geo-location is a more interesting use I've heard about. Given a GPS location using local interference with the magnetometer as beacons to further pinpoint where you stand. Are you near the metal door. Or if you could create a beacon to mess with it.

[7] "The conclusion from this study is that some smartphone models are indeed capable of detecting and measuring geomagnetic storms with a high enough fidelity to be of some value to studies of actual major storm events spanning a wide range of latiudes. When taken under environmental conditions where the temperature is stable, where the smartphone is situated on a level, vibration-free, non-magnetic tabletop, and where no external electromagnetic interference (motors, air conditioners etc) are present, sensitivity levels can closely approach the ±0.2 µT noise limit of the electronics and allow the detection of the stronger geomagnetic storms.

Inflation is almost never caused by government spending. It’s caused by regulatory policy that allows, for example, bubbles in real estate or by external shocks like oil and so on. The whole “fiscal policy will debase the currency” thing is blown way out of proportion. I should also point out that there are much better financial instruments than cash to hold long term savings and they’re being made ever more accessible.

The benefit of a government supplied digital currency is a payment system that isn’t run for profit.
Hi, author of TFA here. Thanks for your comments :)

You're right the harmonic model used is a bit of a bodge. I didn't know that about hammer position, very interesting. Let me know if you ever get around to trying different timbres in the code.

I think we are more in agreement than you think on clustering, though. Although I neglected to discuss what's anatomically reachable, and also the nuances of history, my point is that the desired subset you mention can be defined by using clustering to pick a subset that sounds good.

"Blockchain" is close to useless unless it is coupled with being public, permissionless, borderless among other things. The companies that jumped on this "Blockchain" "DLT" nonsense bandwagon to this day do not understand any of the fundamentals. Just using a distributed ledger does not provide any benefits that they try to borrow from likes of Bitcoin. Distributed ledgers have existed for decades.

Anyone that holds bitcoin is using it everyday as a store of value. It's unnecessary to go into all the reasons Bitcoin makes sense in this thread, plenty of resource out there. Suffice to say that by any measure, market determined or otherwise, Bitcoin's usage has constantly (or even exponentially) increased since inception. Either this hoard of people are getting more and more wrong every year, or perhaps you're looking at it from the wrong angle.

You mean C++.

C usually comes out a bit worse because it gives even less information to the optimizer.

And thanks to the GNU/LLVM monoculture most languages should perform roughly the same if they have them as a target e.g. I have found that D makes its it ridiculously easy to write highly specialized code that is both readable and visible to the optimizer (I will be blogging about that part later), but I'm sure I could force the same asm out from C++ or Rust etc.

Using Pyo3 is arguably the most idiomatic way of interfacing Rust with python. The "added library" cost mentioned as an excuse not to use it is literally the 1 second it takes me to write `cargo add pyo3` .

They didn't do this because it would make their claim that "Julia is the better language for extending Python" kind of moot.

They started from the conclusion that they wanted to have, and worked their way backwards towards implementation and data that would support it.

This is an article about a fallacy, not about tools being unnecessary.

A great surfer can catch a wave on a dining table. But when he's competing in the world championship, you can bet that he'll have strong opinions about the board he's using.

I can write a working program in Notepad, on a dare. But when I'm serious, I'm going to have strong opinions on which tools make me faster, better or more productive.

The article's examples are all about magical thinking from amateurs and beginners, who won't benefit from any qualities the tool might possess until they learn. But when you're a professional, a certain amount of research and a willingness to try new tools and approaches is definitely worth it.

You are correct about the pricing it seems. Either they changed that, or I misremembered. Anyway, 50€/m is still way too much for hobbyists.

I think you missed the point. It's exactly the answer to "not everyone can design clothing".

There's one more I'd add to that list. Not asking for the usual stuff (e.g. references, proof of qualifications etc) after you accept the offer.

The worst three jobs I've been in did that. I found that the work culture in these companies was "impatient" and where corner cutting was the norm. They wanted you to hit the ground running and figure everything out for yourself. They were also very willing to let go of probationary staff after only a few weeks rather than give them the time to get accustomed to the job.

Cash is rarely verified. Sure they might do spot checks to see if its a fake. but its rarely tied directly to a deposit.

So when a cash machine gives you money, the ID of the currency not be tied to your account. When you spend that money in a shop, those notes will not be attached as having come from you as a customer.

With bitcoin, that all comes for free, we know when money left your wallet, what addresses it passed through to get to someone's else's. the whole selling point of bitcoin is that you can trace the provenance of each transaction right back to when that coin was originally mined.

For example, if I was to use bitcoin as a bank account replacement, everyone would know my employer, they would know how much money I give to my spouse each month. They would know who I invest with. They would know when I do my shopping at the super market. They would know when I'm having work done at the house. They would know if I got a bonus, and how much.

Some of those things I'm ok with, but a lot of things, I'm not

I'll defer to your knowledge on that. I generally don't work with Python. I've only looked into interfacing C# with Rust and it looked crazy, so that's where I'm coming from.
