I think you are confusing what you are used to vs. what is easier to learn & work with. Maybe you do have a size 47 shoe (eu metrics) but most people have feet that are significantly smaller than a foot typically by about 20-30%. I'm pretty sure that was even more true when feet were first used as measurements.

Historically, the way people measured things just wasn't very accurate until requirements for that became more precise around the 16th and 17th century and we figured out how to use precisely calibrated instruments rather than misc appendages. This is roughly when people figured out how to build clocks, Newton sat down and wrote up a thing or two about physics, and we started mapping the world in a bit more detail than "here be dragons", etc.

Precision engineering emerged during the industrial revolution. Once people started worrying about tolerances of less than a tenth of a millimeter, it kind of required consistency to get any kind of repeatable results. This required standardization. This happened late 18th century. Of course there were several competing standards.

The reason feet and miles are still around was the historical disagreement between the French and the British over lots of things (including territory). Particularly at that time when they were in each other's hair pretty much all the time. So the British came up with their own set of standards and Napoleon imposed the metric system on most of Europe. The US of course had its own set of disagreements with both the British and the French around that time and felt it needed its own standards. Hence it kind of matters whose miles, feet, gallons, pounds, pints, and what not we are talking about since there are some notable differences. Also, this changed over time. E.g. the US mile was last redefined in 1983, though not unanimously (from wikipedia):

"The United States redefined its yard in 1893, and this resulted in U.S. and Imperial measures of distance having very slightly different lengths.

The North American Datum of 1983 (NAD83), which replaced the NAD27, is defined in metres. State Plane Coordinate Systems were then updated, but the National Geodetic Survey left individual states to decide which (if any) definition of the foot they would use. All State Plane Coordinate Systems are defined in metres, and 42 of the 50 states only use the metre-based State Plane Coordinate Systems. However, eight states also have State Plane Coordinate Systems defined in feet, seven of them in U.S. Survey feet and one in international feet.[77]
"

It seems the issue is highly political; which is weird for an engineering topic.

Fastly was also down
It isn't helpful, though. It creates false rules for folks, and his conclusion is false.

It doesn't take long to explain where such rules came from and the effect they have. He's just parroting an "art rule" that isn't and then explaining some of his own process while acting like it is a hard-and-fast rule. I should mention that this "art rule" is the most commonly repeated "art rule" that folks repeat. I've had this conversation before.

(Seriously, I'm sitting here from the side of helping others people do art when they are a beginner, and have for some years. I've taught a weekend art class for children and have been making art since I was young - I started oil painting before I was 10. I'm over 40 now).
This is good feedback that hopefully the devs will take onboard. I know they were hiring mission designers recently. Hopefully they'll improve the training, because you're missing out on a lot of you didn't really get past the tutorials.

Unfortunately they missed quite a few important things in the missions (another commenter mentioned not being told to retract flaps after takeoff).

I do wonder if part of the interesting aspect of this being a sim is that you can actually go online and watch or read a real flying lesson. Perhaps that's the direction they're trying to go in? So far, the community has been doing really well in fixing up scenery, perhaps Asobo are hoping for others to fill the gap with mods.

Re needing to pay, I'm sure there would be excellent free content on learning it (in fact there already is online), but with value added structured lessons as a potential mini product.
If anything, these kind of issues we see popping up here and there are proof of the high availability of the Internet and specifically how protocols such as BGP helped on making it what it is today.

It is not that we have built the Internet despite BGP. We have built it thanks to BGP. If we didn't have BGP we would have to invent it :)
There's a more reasonable middle ground where independent fact checkers take that on -- that at least has a chance to get monitary influence out of the picture
You're spot on with the mental models. If I try to imagine a gallon, I think of 2x2L bottles, one of them not quite full. A pint and I imagine a 600mL soft drink or water bottle. When you start having to do double conversions (eg miles per gallon) it becomes hopeless - that means nothing to me - and I have to convert to l/100km.

These "intuitiveness" arguments are silly. It's whatever you're used to. So with that realisation, we may as well choose the more universally self-consistent and useful system, which is indisputably metric.
NewSQL Evaluation: TiDB and YugabyteDB
Oh, I totally got that the math was bonkers, and it's weird that it took so long to fix it.

My point is that even in contemporary times there's sometimes significant inertia against finally fixing other objectively bonkers measurement systems in outlier communities.

The best is when your computer crashes with a blue screen right in the working on something, then adds insult to injury by doing updates for the next 45 minutes after the restart.
Little misleading title: each particle moves with exactly speed of light through spacetime; the time is just the direction in which it moves through it (relativity says time is individual for each particle).
"Firstly this is comparing autopilot to self driving"

No I was not. I understand autopilot is not self driving. But since even basic collision detection is still difficult the step from autopilot to self driving will take years imho.

"Second there is the fact that cars that are self driving will still crash at launch."

Maybe. But imho that day will still be years from now.

"Finally, I guess, will people believe in the statistics or will they go with their beliefs."

When self driving is ready for the road I believe it will be much safer than people behind the wheel. Systems like adaptive cruise control, lane keeping and autopilot are already safer than people.

The problem right now is that all the 'glitches' are potential deadly.

Imagine all the cars in the world would to become self driving with the current tech. It would be a mess.
The moment self driving cars would make less of a mess than humans it will be ready for the road.
Perhaps i am just a stupid Neanderthal, but the recent urge to "adjust the language" is something i really don't like... i realize it is based on good intentions, but it feels to much like some orwellian newspeak in the making.
Only run for 12h a day, transmitting every few seconds, and transmitting very few bytes.

Even so! I thought I was moderately familiar with battery powered radios, but Lotek claims the NTQB2-1, which masses 0.26 grams, can last for 103 days at a 29 second interval. Their product photo shows it attached to a dragonfly!

None of their documentation says what the EIRP is. I wonder about the effective radius. If you miss a transmission, that data is gone forever, of course. No way can it afford the power budget for acknowledgement packets.
The pollution from solar panels is absolutely miniscule compared to the pollution produced by fossil fuel power. By a gigantic margin.
Earlier we used to have multiple web apps with separate databases, now we are using a single web app that can connect to different databases and configuration based on the subdomain, so far it's worked great, having a single web app really makes development and deployment a lot easier.
We often host multiple databases in a single rds instance to reduce costs.
We get data isolation and don't have to deal with sharding, of course this works well for enterprise applications with just 50 - 100 tenants.
Instead of burning in place, could the plants be chopped down and used as fuel to generate electricity?
It is a quick pen. On the surface brilliant. But I can't imagine a use case in my projects and the faux Latin isn't helping me. Plus the negative margin is Jacky to me although standard fayre in pre Grid days.

I would prefer a more boring but simpler to code world of CSS. However I am going to look into flexbox more. Thanks for your pen!
Well you sort of betrayed yourself imagining all those hapless foreigners, struggling to fill their cars in multiples of 3.8L ..

In most countries you could go your whole life without having to know what a "gallon" is or even hearing the word.
This domain appears to have used these two bizprime servers for almost two years, however they only return a generic IP address which most likely serves that "for sale" page.

Currently, however, the domain does not point to these nameservers but to ns3.aqadvisor.com and ns4.aqadvisor.com instead. DNS glue appears to be present for these two servers, however they themselves do not consider themselves authoritative for the domain (and don't return their own names) but only refer to bizprime again.

The whole DNS setup is somewhat broken and needs fixing by the site owner.
I liked the speculation in this piece. It was well marked as such and just seemed to be "here are the umpteen possibilities that come to mind" from an expert perspective. I don't know enough about backbone networking to speculate like that myself, so it was really interesting to me to get that perspective on the problem solving process for a company like Cloudflare.
I've been using MacOS for nearly 15 years now, and I've only just discovered that the Finder toolbar can be customised.

In fact you can park your own shell scripts on it, although setting that up is a bit of a performance.
People still do that on Zoom, at least in meetings I (have to) attend.
Show HN: Paroxython - recommend Python exercises based on algorithmic features
I've been teaching programming with Python at various levels for the last 15 years. Over time, the exercises, examples, algorithmic patterns I accumulated for these courses became so numerous that I started to have trouble finding my way around: which ones to present in which course, in which order, at which time, and with which expected benefits?

I developed a tool to help me answer these questions, and more generally to rethink the structure and content of my curriculum. After a few years of tinkering with a rough implementation of these ideas, I decided to rewrite it from scratch with the hope of making it useful to my colleagues, and anyone facing the same issues: this is how Paroxython was born.

How can you use it? In a preliminary step, you make it tag your collection of educational Python programs. Then, whenever you want, based on the things your students already know, the concepts you intend to make them discover or practice, and those you wish to introduce later (or never), it recommends you a list of programs roughly ordered by increasing learning costs.

To all of you who are going back to school in, and despite, these difficult times, I wish you a year filled with beautiful human and pedagogical experiences.
How to Setup Email Marketing Using Google Apps Scripts
And why would a quarter of a gallon be more convenient or 'divisible in human unit' than a quarter of a liter...?

Say, I walk into a bar. I order a beer. Here (in The Netherlands), since I didn't specify, I get a small beer of whatever's on tap. A small beer is 250ml-350ml, depending on the establishment. I could also order a half liter (500ml) or ask for a pitcher. So, just as in the US you don't order "can I have 128 fluid ounces of beer" you don't order "250ml of beer" in the rest of the world. Also, the fact that it 'sounds exotic' says more about you than about the system... and 'guaranteed not as exact'? Really? Let's say you have to measure a gallon of water, and I have to measure a liter. I just whip out a digital kitchen scale and measure 1000 grams. Which is EXACTLY the same amount as 1000 milliliters. Cause, you know, metric units are interchangeable. I double dare you to come up with a more exact measurement in Imperial units using simple kitchen tools.
Netflix is probably using emails from 500px's data breach for email marketing
I've been using username+secondarykeyword@gmail.com trick for quite some time.

Earlier this year, I started getting weird emails from Netflix. They're weird because I'm already an active Netflix subscriber, but the emails are for inviting me to join Netflix.

When I took a closer look, I noticed that the email was for username+500px@gmail.com

Screenshot: https://i.imgur.com/wG0IhUK.png

I only ever use that email for registering with 500px. I'm also aware that 500px experienced a data breach on 2018.

So I'm highly suspicious that Netflix is using emails info from other websites' data breach for marketing purposes (knowingly or not).

This is very worrying, IMO.
To me it sounds mostly that you like it because you're used to it. For me doing DIY projects in mm feels very natural (basically every measure is an integer), much more so than seeing videos of Americans juggling fractions.
Typically yes actually, the director of engineering should always be an engineer. Of course, these are hardware companies so it would probably be some kind of hardware engineer.
Those boots are for walking all day (eg: infantry) - not walking very fast.
> I typically prefer imperial measures in simple projects because they tend do feel more practical.

I posit that you almost definitely prefer imperial measurements because that's what you grew up with, and consequently have the most familiarity, experience, and comfort with.

And that's okay.

But it doesn't speak to objective practicality.

Papercraft - somewhat aside, have you looked at how ISO A series paper sizes [0] are determined? Now that's an exercise in gorgeous and thoughtful standards design.

I'll point out that I do a fair bit of woodwork too, and my equipment - rules, squares, drop and band saws, router table markings, screws, bolts, drill bits, etc - are all metric. I have a tiny number of imperial items (eg a dovetail jig from a company in North America) but they tend to not have to interact with any metric gear, and finding metric versions of these tools is difficult/expensive.

All of us metric-only people (let's say ~95% of the world) are just fine using what they grew up with to make & build stuff -- so it's going to be hard to demonstrate that imperial is 'more practical'.

I think in general macOS is an amazing operating system, recent Catalina bugs aside.

Something related: what I've been really living with is the T2 chip kernel panic hardware bug. Over 3 different models (the 2017, 2018, then the 2019 16-inch MBP which is my current), I've seen Apple go from:

- The initial full-scale buggy behaviour of 1-2 complete system crash & forced reboots per week;

- to Apple suddenly deleting all my previous system kernel crash logs (and no longer recording new ones in Console.app) without my consent or knowledge even though it's my own machine that I paid over $5000 for (must be silent updates of some kind because it happened in between macOS updates);

- to observing Apple slowly tweaking how macOS responds to the kernel panic by no longer crashing the system but just freezing the screen and all controls for up to a minute (while sound continues) before unfreezing itself (this happens maybe 3-5 times per week for me, even more, it happens when watching full-screen video in any app).

So they've improved it but it's still disruptive and noticeable, and plain unacceptable on hardware this expensive.

Yes, I'm slowly planning a move to Linux, but it's not easy, it will take time and it's a major adjustment depending on what your computer needs are. Linux Mint Cinnamon seems the safest bet to me.

I say all this knowing how catastrophically worse Windows 10 is in terms of bugs like Windows updates suddenly hard deleting your entire Documents folder.
Did you actually look at the link that I posted? Those are the numbers for all of 2020.

Germany doesn’t depend on French nuclear power. Germany was a net exporter to France in many of the last years.
Many neighboring countries have even higher percentage of renewables (Switzerland, Austria, Denmark, Norway which is connected via nord.link).

Even though I would have shit down fossil fuel power plants before nuclear, Germany still manages to decrease fossil energy use in their energy mix: https://de.wikipedia.org/wiki/Energiemix#/media/Datei:Energi...
Traditional unit in metric crafts is cm and the smallest traditional distance is 0.5 cm (pronounced "half" not "O point 5"). Notebook grid is 0.5 cm for example and you write and draw everything at shool on that grid so you get used to it (and get intuitive feel for how long a cm (2 grids) is in the process).

The dimensions you're mostly using are 0.5 cm, 1 cm, 1.5 cm, 2 cm, 2.5 cm, 5 cm, 10 cm.

> A quarter inch generally seems right for a small spacing.

A quarter inch is 6.35 mm compared to 5 mm (0.5 cm) which is basically the same for estetic purposes, any preference will be caused by familiarity more than any objective criteria.

> 1 inch and 1 half inch feels easier to keep in mind than 1 centimeter and 5 millimeters

Nobody says or thinks "1 centimeter and 5 millimeters" just like nobody says "I'm 1 meter and 80 centimeters tall". You're "180 centimeters tall" or (less often) "1.8 m tall".

There's even a word in my language "półtora" which means "one and a half", so 1.5 cm is just "półtora centymetra". But even with languages without this word people think "one and a half cm" not "one cm and five mm". You almost never mix units in metric in the same expression, it just makes everything difficult for no reason.

I think Americans don't understand that decimals are second nature to people using metric. When you write 1/2 we write 0.5 but we think the same - "half".
Just an aside: exploring the implications of relativity in a Euclidean space is the basis of Greg Egan's "Orthogonal" book series.
Usually the unacceptable performance tends to be argued with developer personal point of view, instead of profile data in the actual production deployment.
I've found that instant messaging works well for that.

Or maintaining a design/decisions page for the project if there are multiple stakeholders.
It's just about what you are used to. For people who've grown up with metric units, it's natural to work with them.
Usually? Based on what evidence? Writing actual code as a member of a team is the best way to learn a new language and set of tools. What some may call “bad habits” are more accurately called different habits. We can’t, as a profession, even agree on indentation, so no habits are objectively good or bad.
Germany produces much of electricity itself and imports some.
However, Rust's enum-type members are still named - to my knowledge you can't have anonymous enum type members in Rust.

In the example you gave, the type-of `left` is still `SumType::Left` instead of being just `String`.

I'm not too familiar with Rust to say, but I don't consider this to be a syntactically zero-cost abstraction (even if the wrapper-types are elided by the compiler) because we still have more keyboard typing to do than we should be doing, imo.
Germany is a net energy exporter of 36.6 TWh last year.

I guess what is used there is more or less a toy example. I used state machines once in a game and had quite good experience with it, especially when things grew more complex.

A lot of these abstraction patterns only start to show their true powers when in use in software that grew big.

That being said, I probably wouldn't use state machines there, I would use a type system..
You seem to have something else in mind.

Still waiting for the counter proposal from anyone else in WG14, though.

Instead OS vendors seem to go via hardware memory tagging solutions, than keeping up a lost war, as we have discussed multiple times.
Why would I pay for a beta with extremely low topic-limits, especially when there are great tools that do this for free? I'm sure this is a fine tool, but this honestly needs to be very compelling in order for me to pay in order to change my workflow.

I think I should have soda 'soda', not 'juice'. Here in Romania, things like orange juice and milk are also usually sold in 1l bottles. It's things like Coca Cola and Fanta that are typically sold in either 0.5l or 2l bottles (even 2.5l around holidays; but 1.5l is also becoming increasingly common).
Imperial system reminds of UX people doing engineering. With one system you actually get a working program, guess which one...
You can set active hours through PowerShell:

Set-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\WindowsUpdate\UX\Settings -Name ActiveHours[Start|End] -Value xx

So, while this is a really bad idea in practice, theoretically you could have a Scheduled Task that keeps changing your active hours in a rolling window so you never hit it.
Hey, I know this is a 3 days old comment but, I'm also working in Robotics in Japan is considering leaving current work for remote & freelance work with a previous coworker.

What kind of events do you participate in? I'm having trouble finding much events here, and the only outlet I know for this purpose is MLT.
It's common in the US and Australia and, I suspect, any large producer of fruit with a normal culture of drinking juice. Anywhere that imports 1l seems to be more the norm.

Strange what you say about milk though - I've usually seen the 2l form factor anywhere westerners are common. Could be a local convention?

Start searching for contraceptives and within no time you are not only 15 but also female.
> Use exceptions for control flow. With different exceptions leading to entirely different flows. On C you can use setjmp/longjmp + globals for a similar effect. This will help the maintenance programmer develop thinking in multiple dimensions.

I recommend writing a CustomException class instead. So everytime you see a third-party error, catch it and throw a new CustomException() (Without arguments, otherwise you may carry some bad third-party classes/exceptions in your codebase). And don't forget to catch CustomException at strategic places too, so you can actually throw a new CustomException().
Didn't Chernobyl almost make a huge swath of Europe uninhabitable? Wasn't that the takeaway from the miniseries? That a lot of people gave their lives to prevent an unfathomable disaster?
