Ooh, nice.
It's on https://compiler-explorer.com/ too. But it's too long to type, and so many weblinks point at godbolt.org that I've long since accepted that while its name is definitely "Compiler Explorer", folks will call it "godbolt" and type that into their browser. It's shorter and frankly when life gifts you a surname like mine, why not accept it? :)

I would hesitate to call anything concerning human actions a direct consequence if there is 25 years between the cause and its result.

on edit: instead of repeating the same thing in each response berating me for not accepting that it was a consequence I will put the additional response here

I didn't say it wasn't a consequence, but a direct consequence is generally understood as "an effect that is an immediate result of an event, incident, or occurrence."

https://itlaw.wikia.org/wiki/Direct_consequence

https://www.iadclexicon.org/direct-consequence/

although it is often used for rhetorical effect in cases where the consequence is obviously not direct, I just avoid the usage unless I believe it is direct.

On another note, SMS 2FA needs to stop being a thing. Telcos and their systems can't be trusted if all it takes is someone to hijack or intercept your phone number and texts.
It’s not the same comparison. In the US, it’s complaints per 100 cars. In China, it’s complaints per 10,000 cars. You have to do math to make the conversion.

When you do, you see that Tesla in China still scores way worse than Tesla in the US.

So, it’s more about the different countries and what passes for “quality” in those countries.
Great article and the two most important things to really go forward with are to take notice of what they like and take interest in it. I’ve had to talk to my wife about it, because she doesn’t care for video games at all, but as I tell you she doesn’t have to like them just show interest and ask questions. Just like the author mentions it can chain together to spark other important interests (reading and other skills). I don’t enjoy a lot of these games my kids like, just don’t have much depth or are obvious ploys to get you to spend real money to play to win. But instead of complaining about it I play with them and introduce them to other games.

This is not auto-formatting, it's deeper than that. It is not actually possible to disable Excel's date recognition, although you can re-change the format of a cell after the fact.
A curious aspect of this is that Intel has been doing very well financially despite having been failing technologically for a long time (if you buy the old story that Intel's process lead was at the center of it's market leadership.)

High-volume production helped Intel crush SPARC, Alpha and most of other other high-end CPU architectures in the 1990s. Today ARM is the volume leader that threatens to overtake Intel in performance.

---

Intel has segmented the market in ways that have been long-term harmful. The idea is that they look at every little feature and show that hyperscalers can get $5000 of value from feature X on the chip, so they fuse it off unless they pay $4999 for the special edition. Everybody else pays in die area, development costs, etc.

Intel's I/O choices have long been about controlling the PC platform and when you see all of the "Game of Thrones" mergers involving companies like Marvel and Mellanox so much of it has to do with that. Intel has long been stingy with PCIe lanes -- on paper it might look like you have a lot of lanes but when you deal with the motherboard and (usually less than i9) CPU in from of you will find there are capricious restrictions about how you can use those lanes.

Microsoft switched to Wayland (well, WDDM, Microsoft's Wayland-like framework) with Windows Vista and that was based on having a GPU that could do bulk operations on pixel rectangles.

Intel was mortified that a ATI or NVIDIA GPU would become necessary to the PC experience so they created Intel Integrated "Graphics" that approached the minimum performance required for Vista. If it hadn't been for deep learning and crypto mining, NVIDIA might have gone under. If it hadn't been for the merger with AMD and the SoC(s) for the Xbox and Playstation, we might not AMD GPUs.

Intel did not want to see a transition to PCI4 or an increase in memory bandwidth because they didn't sell products that could take advantage of it. NVIDIA did, so they pushed NVLink. Be it GPU, FPGA, or ASIC, you can't have a revolution in performance unless your workload is crazy compute-heavy or you have a revolution in memory and I/O bandwidth.

Having worked at a media firm, I find this very plausible.

At one point I decided to take a look at my journalist coworkers' Twitter profiles. ~95% of the people they were following were not only other journalists, but other journalists of similar, if not identical, political bent. This makes sense, of course, because people will always prefer to hear viewpoints that reinforce their own, but for journalists this is a problem because they're supposed to be providing information, yet they are especially subject to feedback loops created when they fail in attempting to understand viewpoints that aren't intuitive to them. Worse yet, extremism is almost always rewarded on platforms like Twitter, and because journalists are partly driven by a need for fame and brand recognition, they're encouraged to be openly biased.

EDIT: I don't want to paint all journalists in a bad light. What I described just seemed common in my experience.
Personal computers have an advantage here: it is acceptable for them not to work when they are not directly used by someone. It means they can be stored in safes when not used and have all the encryption keys securely erased when not used. For example, a screen locker could stop all the processes and erase all the keys from registers and memory assuming both disk and memory encryption. And the locker itself could be triggered by some proximity sensor, RFID, camera, whatever, not just input inactivity timeout.

They would be using a pressure differential to transfer the fuel, not relying on just ullage thrust.

You'd be surprised at how low of an acceleration is required for propellant settling and transfer. On the order of 0.0001-0.01m/s^2. At a 310s Isp for the ullage thruster, that's between 0.01kg and 1kg of propellant usage per second. Even if it takes an hour to transfer fuel (on the ground, fuel is transfered in about 20 minutes and in flight, all the propellant is transfered from the tanks to the engines in ~8 minutes), we're only talking about maybe 1% of the propellant needing to be used for ullage thrust and perhaps as low as 0.01%.

Yes, you could.
An idea I had a few years ago which someone might be able to run with is to develop new charsets based on the underlying data, not just some arbitrary numerical range.

The idea being that characters that are more common in the underlying language would be represented as lower integers and then use varint encoding so that the data itself is smaller.

I did some experiments here and was able to compress our data by 25-45% in many situations.

There are multiple issues here though. If you're compressing the data anyway you might not have as big of a win in terms of storage but you still might if you still need to decode the data into its original text.
Done is NOT better than perfect
Excel is from an era when programs still catered to power users. Tools were made to have learning curves, ideally not particularly steep curves, but curves nevertheless. It wasn't expected that users would hit the app running, intuiting everything there was to know about the program in their first minute of using it.

The result is a rich deep program that users can grow into, rather than a shallow trivial program that optimizes for the noob experience and leaves power users out in the cold.
This is often referred to as a bubble chart, and most common graphing libraries support it. An alternative would be a scatter plot with three variables where the third variable, value in your case, is coded by color.
Apple Watch already had exactly this problem in the past.
They look at a few studies too and asked around companies if they handled the issues mentioned in those studies, the most positive result was that some models from one company are now better)probably some of the others are not).

IMO seems that the certifications for this devices, especially for the ones used by medical stuff to decide things need to be better tested.

Other interesting point that I did not consider is you can have a device with an average error under a safe threshold but that gives a much above average error for some groups putting this groups at risk if the people using this devices are not warned about this issues.
But isn't this all the more reason to research the causes and direct the policy measures there?

The fact that a country or group of countries maintain economic sanctions on the country in 2020, tells us little about who dismantled its old regime in 1979.

The commenter also plastered the same embargo commentary elsewhere in this post -- demonstrating its lack of specificity -- and makes no attempt to link the presence of sanctions to causality for the revolution.

So yeah...it's a non-sequitur.

What Is Ammonium Nitrate, the Chemical That Exploded in Beirut?
Here's a quick estimate: The potential energy of the wave will go like mass x gravitational acceleration x height. If the depth (front to back) of the wave is about 1 meter and the height is also about 1 M, then per meter of wave we get

M g h

g = 10 m / s^2;

M = 1 g / cm^3 = 10^6 g / m^3 = 10^3 kg / m^3;

H = 1 m

MGH ~ 10^4 Joules per meter

If a wave comes every 10 seconds —> 10^3 joules / sec, not far from what this person quoted. We need to add to this the kinetic energy, which might double it. Playing with the other parameters we can get close to what the parent quoted.
Many of the restaurants that can go delivery only already did, like pizza places and some Chinese restaurants. But the problem is two fold, many food items don’t lend themselves to delivery, and then delivery itself is expensive and doesn’t scale either.

A large part of the restaurant experience is dining in, even if that doesn’t include the hospitality, the freshly prepared food will be irreplaceable. The moment it’s packed in boxes a lot of the food loses its edge and items prepared by many chefs will all seem similar. If this concept takes it will take the quality of food down globally.

However I am highly skeptical about it and the main reason is delivery, which I still think is a fundamentally unviable business.
> The problem with unions is they reward seniority over merit.

I've never seen a company, union or non-union, that doesn't have a relatively narrow salary range and progression for non-management positions. Of course the base salary tends to be much higher in tech companies, but how much non-seniority "merit pay" do non-manager software engineers actually get? The bigger the company, the more well-defined and bureaucratized the salary progression, even when there's no union. AFAICT it seems largely a myth that large amounts of non-seniority merit raises exist in software engineering. Some engineers can advance through the "rankings" more quickly than others, but overall it doesn't seem much different from union scales. The differences due to "merit" are overall small in the whole scheme.

The two best ways to increase your salary in a tech company are still seniority and promotion to management, which is no different than union shops.

Of course stock compensation can be a big factor in tech companies, but the stock price rises or falls due to market forces rather than individual employee merit.

"Distributed hyper-local private ghost kitchens". (OK, I just mean home cooking).

But looking at your own kitchen as a tiny business, it's pretty clear that market size (OK, I just mean household size + friends & relatives) is probably the key factor in amortising overheads (food waste, labour, fixed overheads like space & equipment, etc).
Famous chefs certainly have existed for a long time, but the thing where any remotely high-end restaurant advertises who the chef is does feel relatively new.

Commercial real estate marketing ideas to help you stand out in 2020
This really isn't a big deal. Doctors know that these pulse ox meters aren't very accurate and use them accordingly. Nobody's changing their plan because you have a pulse ox of 93 instead of 95. They're there to quickly measure big changes that indicate a problem. In other words, they're looking for patients going from 98 to 75, not 98 to 95.
I can't find any information on how inventory management works to see that kitchen waste would be improved.

I see two options:

1) Common inventory, in which case I risk running out of ingredients I need for my kitchen, or the inventory of the facility still has to overstock.

2) I can have my inventory delivered, which still means I have waste to produced.

And if I want to support local farms, is that an option, or is all of my food coming from US Foods/Syscon/etc?

> Still, I find it really hard to understand why (most, yet, not all) societies are so obsessed in regulating the access and consumptions of certains things

Some things are deemed net negatives for society, we already can't trust people not to drive while high or after drinking alcohol, if anyone could buy cheap meth at Walmart I can't imagine it would be a good thing.

I'm all for legalising, or at least decriminalising, psychedelics but some people really can't be trusted to ensure their own safety and the safety of others.
On top of that it's a bit like seatbelts or motorcycle helmets, some people think it's their own choice but when they crash they cost $$$ to the public health system and they're fucking over every single tax payer in the country.

I already know the rebuttal to that point "simply do it safely", well, just as some people can't drink alcohol safely, some people can't handle drugs safely. The only sensible way to legalise it would be to allow it under full medical supervision, which brings a whole other set of problems

> while vast majority of unregulated things can and are as deadly as those regulated.

If you're talking about alcohol and tobacco they're legal because they're historical and heavily lobbied. If alcohol didn't exist and someone came up with it in 2020 it wouldn't be legalised. Tbh in my opinion half the food sold in supermarkets should be as illegal as coke but that's another topic.

(By the way I always found the "if alcohol and tobacco are bad but legal then drugs should be legal" argument kind of moot, the logical conclusion would be to criminalise tobacco and alcohol rather than decriminalising everything else)
There is "sales" and "business development"; these overlap but they are different.

In "sales" you have a playbook that at least seems to work. The reason I say "seems" is that the real metric that matters is lifetime customer value -- you could be making a lot of sales but not a lot of profit in the long term, not have a clear understanding of what is happening, and then find yourself in a great deal of pain later.

"Sales" is an optimization problem of taking something that works and making it better.

"Business Development" is entirely different. If you succeed at that you write the playbook, get big commissions, buy some nice suits and a nice car, get a "VP of Sales" position. A lot of people don't succeed at it.
This sounds a lot like Huffman Coding/Gray Codes, the basis of lz family of compression. No need to change the character encoding, just build a table for text and use that for encoding/decoding.

The basic narrative (chefs used not, in general, be very important, then they became this weird all-important publicly venerated dictator figure who could get away with not only assaulting employees, but actually writing about doing so in books, now there's a backlash against that) doesn't seem that out-there...
So much this. I work in educational software, and have a little write up about the troubles we’ve had with schools “fixing up” CSVs from their student information systems before sending them to us. The simple act of opening the CSV and hitting save loses data (Microsoft actually fixed some of the problem very recently). That said, they will use Excel, it’s not in my control.

I received dozens of comments “Just use Open Office / Libre Office”. I am but a man, I cannot change the world. I forgive that which I cannot control. We work with tens of thousands of schools. Getting all of their administrators to install Open Office, and thousands of administrative assistants to remember to use it rather than Excel is simply an impossibility.

If that were the case, why would we bother separating out code into multiple directories at all?

The reason we bother with modules and directories is to help organize code and ease discovery. And whether we use ls or a GUI, we all start out the process of discovery with a directory listing.

The top-level directory, where these files are, is often where there's the most flexibility in terms of how to lay out things. All this clutter hides the project organization and makes it difficult to discover what's going on. It was one thing when it was just autotools, but the proliferation of tools in the last decade has brought it over a tipping point, IMHO.
