>Coming back to physics, there's an assumption you and other commenters are silently making, which is that quantum mechanics is even applicable to macroscopic objects like humans.

It follows from schrodinger equation, it provides no exception for macroscopic objects. You can say quantum effects indeed happen at the lowest level, and macroscopic behavior follows what happens at the lowest level. It's a question of reducibility.

> The largest objects which have been shown to act wave-like are a few thousand atoms large.

Large objects have wave-like behavior, e.g. you can't determine their size with femtometer resolution, they don't suffer from ultraviolet catastrophe and have macroscopic quantum effects like superconductivity.

Sounds like you are not taking the time it takes to get to know the concepts in git or are not given the time. One does not become proficient in a DVCS in a day. It takes time and practice. It is important to note, that git is distributed. It is a big leap from SVN. What you perceived as simple before might have been a serious risk everyone took.

I've once tried to use SVN before I learned about git. I was terrified to do something wrong. I did not understand the concepts well. I just did not get it. Fortunately I did not stick around with it, but learned a little bit of git shortly after. Then simply Used what little I knew. Then at some point tagging. Then feature branches. Submodules. Pull requests. You learn step by step and don't get overwhelmed by git's complexity.
Isn’t that just because the drone bit is easy and the payload bit is hard. Particularly in terms of procuring explosives, and making them effective and light enough for a drone to carry? Then you need a target that actually needs a drone to attack it versus doing something simpler.
What sort of API is it? Web-based (as in REST or GraphQL)? Or software libraries? Curious the language, in that case...

That would make trade deals with the EU impossible.
Are you sure? Intuitively I would have said, that "I'm one eighty tall" is an abbreviation for "I'm one [meter] [and] 80 [centimeter] tall".

Thinking about it, if I measure something with a folding ruler, I would more naturally say "it's one meter eighty long" (German native speaker here, as already said elsewhere, with other languages YMMV).

But the point still stands. In metric, you can slap the numbers together or separate them, convert them to different units or sprinkle easily units in between or not. It all works. At worst it is just moving the decimal point around or adding/removing zeros. Very easily done in your head.
I think a lot of the gay culture is not well known , even though it's such an important and disproportionally influential little part of western culture. Part of it is because parts of it are considered too racy for todays generally conservative world.
> I don't know what specific model is shown in the picture but if it is a DJI Mavic Air 2 then it only weighs 570 gram and can only fly for 34 minutes.

It's worth what, on the order of $1000? Strap 100 g of explosives to it, fly it to the target's face and detonate. It does not need 34 minutes of fly time.
I'm really surprised at that - I've been running Big Sur as my main OS on my personal laptop since dev beta 2 and it's been pretty solid. A few small rough edges but it largely just works for me.
That’s more of an OS (Linux) adapted for playing games than an OS designed for playing games.
Yeah, people forget how buggy macOS has been. Both Snow Leopard and Mountain Lion were public admissions that they needed to focus on quality. They haven’t had a proper one of those in a while.

That said, I can’t remember a time when bugs have been as long-standing as they are now. SMB file shares have been completely broken for nearly 3 years now (the solution is to buy the program AutoMounter), and USB-C docks have been broken since day 1 and still are on Big Sur.
Do you really do that? It feels like a lot of wasted time...
I'm not the original commenter but I've had this issue where the laptop reboots instead of sleeping properly. Keeps happening, not sure why, and many others have had it too on forums.
I have a rule: if I've been doing the same job for two years, it's time to leave.

Especially in this industry, getting comfortable can be disastrous. There's no job security, ever, but it's remarkably easy to fool oneself into thinking there is. And then suddenly it's gone, and a hostile job market with skills 5 years out of date.
Or they’d just remove the serial numbers.

Having started working remotely just before the pandemic hit (good timing I suppose), I was curious how the daily schedule would be different. I am sure that being at a remote-experienced company is better than companies starting it for the first time in general! In general my meetings are shorter but they also help give me a little of the face to face time I need to ask the random question or get to know my colleagues better.

I am seeing this same situation with my kid’s and his friends remote learning for school as well. We planned on our kid going to remote school this fall and it seems pretty well thought out, but some of our friends had the school switch to remote for the first few months at the last minute. It has been a disaster for the most part! So the lesson to me is to NOT treat remote exactly like in-person... there are advantages and disadvantages but if you try to copy in-person to remote it will not be successful.

Every OS has bugs, I can't see more show-stopper bugs in Catalina than any of the previous ones. Especially none that would stop me from working or being productive.
I'm guessing applications will be running with the old libraries loaded and developers should be able to count on this one-version-only situation (e.g. ABI between processes). Forcing a restart is just the simple but crude way of ensuring that no applications are using any system files (.NET is part of the OS, up until .NET Core).

I tell you one thing. If you think that a company will be offering you new tech after every X months or Y years then you are wrong. Tech world does not like that. Think of the investment a company does to bring in a tech stack. It is not all about downloading a new tech, it is about finding and hiring resources. If they all start changing tech based on wish list then they never can progress. I remember something my ex Boss said years back: We have not married with companies hence we should not try to change company as per our will.

In order to fulfill what you want you should work on side projects. Side projects are great way to vent out tech frustration. Working on PHP and got bored? Try python at home. Tired of using bootstrap? Try Tailwind. Feel angry seeing monolith CRUD apps? Try Docker at home and start making micro-services. You have endless options. You can also put code on Github to improve your resume.
macOS 10.15.6, which is a minor .6 version, should not cause a lot of concern, had a nasty bug with virtualization, breaking virtualbox/docker/..., it was well known within a week or two after the release. So it's not always good to wait for a .x version, it's sometimes more to wait for a few weeks after the release of any version.
Captcha's aren't to identify humans, they are to train AI. It is easy for me to understand the tolerance level, I know which images it understands and which images it likely doesn't. I can easily finish captchas without selecting all images of crosswalks.

Anyway, your point seems to have the purpose mixed up. Pointing out images of crosswalks trains the same system that some cars use or will use.

Would the same principle work for non national currency ? I am thinking specifically of Bitcoin.

Say a bank would accept deposit and issue loan in Bitcoin. We apply the same example as in the article. Someone deposit 100BTC. Another person takes a loan of 10BTC and owns the bank 11BTC. (that would be much bigger value than $100, but the principle is the same)

Would the total number of Bitcoin be higher than before those transactions ? That would break the hard limit on the total number of Bitcoin. My understanding was that hard limit was a key feature of Bitcoin.

Still, I’d love to see more people adopt btrfs because I think diversity in filesystems is a good thing.

Relatedly, I’ve seen many many EU4 maps of countries come up in google results for those countries, which is concerning as they’re often (as is the nature of the game) inaccurate.

At least with CK2, there’s really no harm done if someone sees a fictional portrait of a long dead minor ruler. With entire nations, the story is a little different.
What happens now, when your car breaks in a way that causes an accident? Obviously this is a thing that happens and it is dealt with somehow. It hasn't happened to me, and I'm not a lawyer, so I can't say for sure offhand.

At least in my state, there is no fault coverage everyone has to buy, that covers medical bills up to a certain amount. It does not cover fixing your car. If there is nobody responsible for a collision, maybe the repairs would fall under comprehensive coverage.

From what I read, if you hit a deer, it's covered under comprehensive. But if you try to avoid hitting a deer and run into a tree, it's covered under collision. So it seems somewhat arbitrary.

> which are two foot or 60cm across

That's not exact though. 1ft = 30.48cm. If you are working in your own garden that's probably close enough, but for anything else the errors will quickly add up. Tiles are often made to have sides that are 30cm or 60cm, if you try and tile a bathroom that is 12ft across assuming tiles are 1ft each, you'll get to the other side and end up with an odd piece.

I was born and raised in the UK, and honestly I think we have it worse than the US. At least the US consistently uses the same units (although the wet vs dry weights are confusing). When I learnt to drive I suddendly had to learn what feet mean, even though I'd never used them before in my life.
I would have said Ubuntu a year ago, but I've been watching the Desktop Linux space closely for a year now, and it appears Mint is actually more user friendly than Ubuntu, which is quite surprising and nice to know (I'm not a fan of Snap centralisation either). E.g. the GUI app store is superior, it's been demonstrated...along with other things that actually matter under the 'just works' category.

Maybe I'm wrong.

ScatterScam: Detect and track counterfeit Android applications
Interesting new tool for those who deploy Android apps on :
ScatterScam, developed by Defensive Lab Agency, specialized in privacy and security.
DLA has notably worked on the Facebook data usage survey for the WallStreet Journal in 2019, as well as various in-depth studies of large-scale attacks.

The agency is mainly working on large security audits, but has decided to offer a new Saas tool, accessible at an open price for the open source world.
This tool is called ScatterScam and automates the detection of counterfeit apps, to counter attacks such as DarkCaracal for example.

This kind of tool enables automated monitoring and protection against this type of attack, which is becoming more and more common and can be disastrous both for "fun" applications and for financial applications, wallets, etc.

The tool is brand new, and deserves to be discovered because it saves a lot of time and energy...!

Enjoy!
Cheers Peers!

I find that a lot of junior developers tend to go overboard with creating small functions, and the motivation is largely aesthetic. They have a mental image of what “clean” code is supposed to look like, and it doesn’t involve lots of indentation, curly braces, mathematical notation, etc. So they often try to bury these messy details inside a function.

They don’t have a lot of experience reading and debugging other peoples’ code, so they might not consider how much of a pain it can be to have to go jumping through a whole bunch of deeply nested one or two-liner functions just to see what the code actually does.
Being interviewer myself I can say interviewers tend to be stubborn. They have an excellent question (at least they think they have) that they have spend a lot of time thinking through and discussing with other candidates. Your answer causes him/her to miss the opportunity to have a real discussion and understand your knowledge of the topic.

It is better to play along and only mention the real solution at the end, to finish on a high note.

QuickBooks Is a Bad Joke
“A user interface is like a joke. If you have to explain it, it’s not that good.” QuickBooks was a bad joke.
I think you misread the parent comment. Dividing by 10s is easy, but useless. If you have a kilo of rice, you can easily divide it into two or even three equal subdivisions, without scales or with primitive scales, if you trust the participants. And then you can divide the shilling that you paid for it into three.

The advantages of the old systems exist but they have largely been superseded by modern technology and small currency subdivisions. (Remember that a new penny is worth a lot less than an old penny was, even though a new penny is nominally worth a bit under "tuppence ha'penny".)

Not advocating the old system. I'm 100% metric.
It would be helpful to the reader if the text was easier to see.

A story displayed in light gray on white is difficult to read.
A sum type is a tagged union [1]. In C, a sum type can be modeled by the combination of an enum and a union. The enum would tell you which field of the union you should use. In Rust, enum's subsume unions and enums of C. This is analogous to a a disjoint union [2] in set theory. Notice that in both cases you have a pair of data. Sum types and disjoint unions are both instances of coproducts in category theory, by the way.

(The size of the block is 5 mm or 0.5 cm, not 0.5 mm; I'm sure you know that and it was just a typing error)

You're not supposed to cram your letters into that 5 mm space: you generally use two lines, which gives you a 1 cm lineheight.

That being said, I don't like that raster size for writing. They're nice for drawing schematics and stuff, but for writing I very much prefer a grid of 4mm × 8mm (like this: https://www.dbs.be/images/vergroot/2518_2.jpg).
Introduced ... where?

The distance components were created (arguably) about a hundred years before bits of Europe adopted it.

When I was in Greenwich (the real one) years ago, our guide told the story, which may be apocryphal, that the Brits negotiated with the French way back about the meridian.

The Brits got to keep the prime meridian by agreeing to adopt metric.

Which they then failed do to do for a couple of centuries (and even then ...).

Unfortunately I can't find anything to substantiate this story just now.
To be pedantic, a particle without mass. Matter also includes things without substance like physical fields. So a photon is matter.

Interestingly a current search still shows this, and the root cause is the fact that there are no pictures of Greg Egan available.

This is a fascinating failure mode - Google works on a best effort basis, so it doesn’t have a strong enough concept of “there is no correct answer to this question” or perhaps “my approach is wrong in this case”.
There are sum types, and product types, but what would "exponentiation types" look like?

OK, I might now agree with that. Perhaps it's a second issue (which only makes the criticism stronger). I still do occasionally get the T2 'crash', i.e. entire system reboot, but not very often. What's most frustrating is how Apple's taken away control of troubleshooting and knowledge about one's own device and what's going on with it, for their own business reasons. Extremely hostile to the consumer.
Where this is useful is when the application needs to process much more data than it then needs to transmit over the network.

For a database system like mongodb this could be perfect depending on workload.

This makes me wonder if Google developers ever get feedback from outside the company, it feels like some feature is released and developers move the the nsxt shiny thing and most feedback (the one that does not reach on a news paper) is ignored. Probably this is expected when you have many users and most of them are not paying.
If we're talking about what's common in English, I think it's a little odd to discuss European metric habits in the context of the English language.

While English is a "lingua franca" in Western countries, the two main native-English-speaking countries in Europe are very recent metric adoptees.

Ireland didn't finish adopting the metric system until 2005, so still use imperial units for many colloquial uses; e.g. human height & weight.

The U.K. is further behind, and if you couple that with the nationalistic associations the imperial system will have there, colloquial uses are even more widespread.

I think metric use in English is only going to become more natural and fluent with generational use.

> On the other hand, suppose you have 1x1 km of land three children, and you want to divide the inheritance equally. What do you do? Give two of them 1km x 333.33m of land, and the oldest one 1km x 333.34m?

This is a silly example. You're going to give them all about a third of the land. But the precise measures are going to depend on the land. Perhaps one of them got the steep hill and a bit more to compensate. Or the creek serves as a division between child 2 and child 3 but that just so happens to mean that child 3 gets a wee bit more than half the remainder.

In any case, you aren't going to give them 1 km x 333.33 m unless the law of your state really stangely provides a maximum precision of 10 cm. The system is infinitely divisible and the survey happens once with a fair degree of precision.

There are good arguments for the convenience of non-metric systems. This one is just a terrible one.
Writing on a page (4KB / 8KB) boundary is almost always a good idea. Because there is an overhead per page that you have to account for.
It can be in the range of 16 - 64 bytes, so having a 256 mini page is probably a bad idea.

Most of the _data_ is also not going to fit in 256 bytes anyway.
