2 days ago my wife and I hopped on 737 MAX plane for the first time.

"This is it" I told my wife giddy when I saw the MAX 738-8 bold letters on the emergency pamphlet.

"This are the planes that came down due to the..."

"Stop it!" Shouted her because I was about to start one of my long engineering diatribes.

My anxious brain had acceptance on putting my life on the hands of well meaning people.

Other's anxious brains rather not.
Everything about KPIs in this blog, Goodhart's law, the comments... it's all true. That said, I'm not sure KPIs themselves are the centre of this problem.

A national olympic team (or any competitive sports team) using KPIs probably would not experience these problems. They might get over-exuberant and over optimise slightly. Athletes might game the system slightly. But, it's unlikely that a professional sports team degenerates to levels of KPI affliction like an average corporation.

No matter the corruption, olympic teams are made up of people who really want to win medals. Athletes, Coaches. Dieticians. Managers. Administrators. Etc. They're not angels, they're just not as focused on appeasing their boss, managing up, and such.

Group size plays a role. C-level distortion fields play a role. The orgs age. etc. Legibility. "Market" feedback loops. It all ads up to an organisation that can take any management tool and make it pathological.

A commercial example of resilience to bullshit is a classic factory, that ideal "Firm" we based out economic models on. "The job" of manufacturing objects is legible, can be effectively reduced to component parts, measured and optimised. The feedback loop any significant successes and failures is effective.

A young startup with a "lets make it work together and we'll all be rich" vibe can probably use KPIs effectively. There are lots of example, and we intuitively know how this is going to go.

I think it's time to look at some microeconomic questions with the reverse of conventional logic. Why does the financial services sector have sop many employees? Not because of the marginal profit value of the least employee. Because of the revenue. A company with $Xbn and a fat profit margin is (often) going to employ lots of people because it can. At this point, all you need is to lower efficiency to achieve the required output.
Then there was Margret Thatcher who decided the internet was a fad and wasn't worth investing in internet infrastructure in the country.

I wish CEOs would stop flying long haul just so they stop having the time to read the management book du jour and inflict this silly things on the entire company.
They aren't terrible business people at all!

If they collected much more profit from each device sale then they wouldn't have market-dominating IP. Because they'd have competitors who could undercut them.

As it is, a tiny firm of people make an extremely good living off a margin that nobody in the business can really quibble with, and it has without conflict sustained them to do greater and greater work that has changed the world.

You watch: ARM post-IPO will inevitably have to start squeezing more juice out of the market to give to greedier, more transactional, more activist shareholders, and this will fuck up the balance entirely.

An ARM IPO isn't really going to be good for anyone, I think.
You've defined down "hacker" pretty badly if debatably not using a publicly accessible website for its intended purpose according to the posted terms of service now qualifies.

Exactly this.
Traditional dance today has to compete with the electronic dance music scene. Since the latter largely goes back to gay, Black clubs of the 1970s and 1980s, it emphasizes “be yourself” and “express yourself” values. Not only could you show up as a total freak, wearing drag or
leather etc., you were celebrated and welcomed as royalty of the community for doing so. So, electronic dance music has a cachet of racial and LGBT acceptance that folk dance just can’t compete with when it comes to drawing younger generations today.
Check out Greensky if you haven't already. A lot of Billy's recipes were adapted from their book.
A society can do multiple things at a time, and it's a more efficient use of resources to do so. Progress made in an activity versus resources put into it is generally logarithmic or even asymptotic when investing extreme amounts of resources, so if you have a huge amount of resources to spend (like a country does), you can get more done in total if you spread them out a bit instead of focusing on one thing at a time. Sticking another billion dollars into fixing housing would have a negligible difference. Finding solutions to something like that requires experimentation, data gathering, and deliberation, which all take time. Putting people on the moon will not affect the passage of time for those of us on Earth. (And it hardly affects the passage of time for anyone on a rocket, as well.)
I am guessing part of the push of politicians into "the Internet" is because they do see this effort of the tech community to minimize them. They see themselves as representatives of the people of their countries (especially democratic western countries) and so they should have a say about how the Internet works rather than unelected groups of technologists. I heard this repeated several times in meetings where Internet governance is discussed. You may agree with that or not, but that's their point of view.

I don't know if tech could ever be completely separated: infrastructure needs physical locations, tech companies have employees who are citizens of somewhere, etc. The Internet grew because it wasn't seen as a threat at first, or the benefits outweighed the risks. Now, an instant, global communication network that is critical to the economy means it's seen as too important to leave up to a bunch of computer nerds.

You may be right. In that case they should offer a dividend to attract the kind of investors who are not necessarily looking for big gains in the stock price, but want a nice stable return. ARM was a growth stock for decades, but that phase is over for them.
Owning a stock is a verb. Allocating capital takes a lot of work, and a lot of courage. Gordon Gecko is a fictional character.

Having said that, Blackstone/rock has grown far too much. People need to stop sending their money to their index funds.

> A company doesn't need to have a Nvidia like P/E ratio to be successful.

Absolutely true. Sadly nowadays, especially in the US, and especially in tech, unless the company is growing like crazy or massive, it's considered as insignificant and dimissed.

I knew a guy at work a couple of decades ago who was extremely sensitive to organic vapors. Simply opening a dry erase marker in a nearby cube would send him to get medical attention. He wasn't faking it.

At one point he was trying out an air purifier from NASA that used UV light and titanium dioxide to destroy organic contaminants. The light creates electrons and holes in the TiO2, causing the contaminants to be oxidized. As I recall it didn't work well enough for his purposes (or perhaps created degradation products he also reacted to.) The notion of using TiO2 to make self-cleaning surfaces is also a fairly old one. One proposal had cars with TiO2 on their radiators, with the idea they'd destroy more smog than they'd create. If I recall correctly there are also TiO2 coated toilets in Japan.
One of the truths I've come across over my years is that almost without fail whenever code is mentioned, someone will come across to show how it could be done better. I haven't seen it in this thread, yet, but generally there will be someone who will maximize how badly it could also be done, usually using Java and invoking "Enterprise coding" memes.
It's worth noting that SpaceX's major development change is to "hardware rich" and test often.

That's something you can do launching rockets. It's something you can do in orbit. And for deep space the moon is close enough (and by many measures, harder then Mars to land on) to safely yet effectively test practical systems of the type you'd want to go to Mars (consider: Mars' atmosphere is incredibly thin, so it's more Moonlike then Earth like).
A decent number of Brits know about the Raspberry Pi, but it is true to say that a hell of a lot more know what the BBC micro:bit is.

Bear in mind the history (from Wikipedia)

> IBM originated from the unification of several companies that worked to automate routine business transactions, including the first companies to build punched card-based data tabulating machines and build time clocks. In 1911, these companies were amalgamated into the Computing-Tabulating-Recording Company (CTR)

Even 130+ years ago, replacing humans doing routine-enough-to-automate work was the main objective.
Breadboard specific cut and formed wires such as these: https://www.amazon.com/AUSTOR-Lengths-Assorted-Preformed-Bre... [1] will make both wiring, and verifying, bread-boarded circuits much easier. Plus the actual circuit will be much neater with these wires interconnecting everything.

They have to apply for a visa/license to marry, which can be denied or take a long time or require whatever documents the authorities want, and I have the impression it requires them to leave the country too, before they are able to get married in Germany, but if they can travel and get married in Denmark without such difficulties then Germany automatically accepts the marriage.

Many countries don't allow non-citizens to marry citizens without an onerous administrative obstacle and/or a long time delay, and possible refusal. Unlike business travel visas, in some countries lack of formal permission prevents a marriage from having legal marriage status, so it's not like you can just quietly ignore the requirement.

Occasionally two people who want to marry can't do so by any route in either of their home counties.
Oh god no. Not this rubbish again.

Being wrong is not lying. (Edit: Again parent comment was edited.) However, I am not wrong with currently presented facts, of which you are free to bring yourself and haven't as of yet.

First Google result: https://time.com/6273065/space-travel-climate-impact/ and https://research.noaa.gov/2022/06/21/projected-increase-in-s...

> Indeed, according to the NOAA report, a single passenger aboard a rocket is responsible for 100 times more climate-changing pollution than a passenger aboard an airplane.

> The researchers found that this level of activity would increase annual temperatures in the stratosphere by 0.5 – 2° Celsius or approximately 1-4°Farenheit, which would change global circulation patterns by slowing the subtropical jet streams as much as 3.5%, and weakening the stratospheric overturning circulation.
You're just making an assertion that my claim is incorrect. Practical experience shows - consistent effort does indeed deliver results, and leads to improvement in capability (by and large - as pointed in my original answer). For example, the whole education effort of 14-15 years is full of painful experiences, getting wrong answers in math, flunking in laboratories, etc. There is stress involved during the examination. If I simply avoid the exams citing stress, how'd I ever become capable?

Therefore, I don't see how you could be correct on this.
It just describes how two probability distributions are different. If they are the same then it’s 0.

Example: an LLM gives a probability distribution of the next word. If it is perfectly accurate at predicting the next word then divergence is 0 (100% probability on the actual next word). If it is slightly off or unsure then the divergence goes up.
Yep. We still control:

- Puerto Rico
- U.S. Virgin Islands
- Guam
- Northern Mariana Islands
- American Samoa
- Baker Island
- Howland Island
- Jarvis Island
- Johnston Atoll
- Kingman Reef
- Midway Atoll
- Palmyra Atoll
- Wake Island

However, we also lost a bunch of territories between 1948 and 1982, particularly the Philippines and the Panama Canal. Can you imagine how much richer we'd be if we had developed the Philippines into a manufacturing hub right before China became one?
That isn't even close to a consensus view.

Why are you asserting something as fact, when it's simply not, and has many competing views with just as much wood behind the arrow?
I took beginner improv comedy lessons from BATS in San Francisco, and also saw several of their shows, and it was a revelation.

The cardinal rule of improv is "Yes, And": If your partner exclaims "Oh no, our house is burning!", then henceforth your house is burning. You might respond: "Fluffy!" Whether Fluffy is a cat, a dog, or something else then depends on how your partner reacts.

One thing that struck me is that improv is not about trying to be funny, it's about building a connection with the other actors on stage, and about welcoming the unexpected and rolling with it. I think the same could be said for most humor in general.
Neat project! Thanks for sharing!

"broot" also lives in this space, but is rapidly getting too complex for me to memorize without consulting the help page.

parallel is one of those tools like jq, to me. It's great, but by the time I've grokked the syntax, AGAIN, I'd've been quicker to write a quick shell/ruby/python script to do it that's almost readable.
On unix you would have had to write that script anyways unledd maybe jq can help (?). I usually use convertto-csv and it works like a charm. Powershell is more like python than bash.

If you learn .net stuff it might make it more easy to use. You can access .net functions from powershell, so had you written that code in c# instead if node, you could reuse it in powershell anytime you want.

Although, personally I use shells to test stuff or for basic things, python kicks butt regardless of platform.

I hope your work let's you use wsl. If not, try running powershell.exe -version 1, that let's you bypass constrained language mode if that is the issue. Also, lookup set-executionpolicy and unblock-file, in case those are what you needed for the not allowed part. You can even bring your own powershell entirely! Powershell itself is an interface around System.Management.Automation windows/.net assembly. There are tools used in red-teaming where you just bring your own powershell interface and bypass any restriction. Even if you can't bring new exe's, no problem, you can relectively load assembly's and run them in memory, with or without powershell. Your org must be setup Crazy good if you have windows and there is no way to do whatever you want in powershell without admin rights. But don't get in trouble because of my advice!

Basically Governor-General (the Queen's representative of a country) John Kerr did it without approval from the Queen.

We have the same system here in Canada but if such a thing happened here there would be riots in the streets. Especially Quebec and First Nations. But really anyone would be very mad and we would probably drop the monarchy that day tradition or not.

Are you allowed to install Cygwin? It does a lot for making Windows a civilized environment.
Do you see twitter though?
Ah right. There's no read-only hardware registers that ID product & supported features?

Said hw registers non-moddable by firmware?

If such hw registers don't exist, why not?

If they do exist, what's the problem with firmware claiming support for x, y or z when the hardware says otherwise? The market will weed out shady sellers soon enough.
And not a rare one, there's regularly depressing crowdfunding for people struggling to get basic things in the US (met by incredible donations for sure). The culture makes it acceptable, it's weird.
Yeah, I seem to recall the US having some big dust up about people working and not getting paid for it?
See, I CAN program C++. I still prefer Rust.

“Some people who can use other systems fine, can’t use my preferred system” is possibly the worst defense of a system. It’s bad. It’s not something to be proud of.
I agree. I hated walking in the city I lived in Canada before moving to Tokyo. It wasnt very walkable and you really needed to plan for any type of long walk as you might end up in a place with no food or drink shops anywhere. The way Tokyo is zoned allows for every possible convenience I need within a mile of everywhere I walked. I felt extremely safe at all times too which made things way less stressful and allowed me to be completely in the moment.
And prisons! We made incarcerating people into such a billion dollar business that we have more prisoners than the top 3 leading countries combined

> A blackbody is an optically thick medium in thermal equilibrium.

Black body can be simulated by a cavity with small hole, so incoming light will be scattered and fully absorbed, with zero reflections. In case of CMB, light from our Visible Universe will never return back to us, because it will be too weak and too stretched.

Moreover, this is really big journey for a photon, with very high probability to hit something on the way to us, so we may see a large portion of re-emitted EM radiation instead of the original light.

What is the difference between black sky and black body?

> Galaxies are not blackbodies (not even close), and when you average a bunch of non-blackbody spectra, you don't get a blackbody. You'll get a spectrum with all sorts of atomic and molecular features.

Emission from multiple random objects can be approximated as black body radiation, even when they are not in thermal equilibrium with their surroundings.

Moreover, we use statistic to distinguish between different emitters. In case of CMB, years may pass until we receive second photon from a same galaxy. Statistic doesn't work in such extreme cases, unless we will point an antenna in the same direction for a millennia or even longer.

> There is actually something called the "Cosmic Infrared Background," which is caused by distant galaxies, but it's not a blackbody and it has much larger amplitude variations than the CMB (because galaxies are distributed in a clumpy way).

CIB emitted mostly by stars and dust particles, which are hit by the star light, which are much closer to us than CMB emitters. We may get different picture from outside of our galaxy, or when we filter out local emitters.

> Spacelike surfaces of constant coordinate time are flat, but the whole manifold is not flat.

You are talking about model. Can you map your model back to physical reality, please? As I understand, you are trying to tell me that a point in the non-flat space-timecan have less or more neighbourhood points that in flat space time. In other words, wormholes or space-bubbles are possible in your imagination.

> then you need to learn the basics of General Relativity.

I'm too stupid to understand this great theory. I need simple explanations.
Vox link, I already imagined the reasons they were going to give.
Your question has been answered, see below. And perhaps you would be glad to hear that the "narcissistic exploration of space" has actually lead to greater care and concern for the planet than we had before we started the endeavor.

>However, I believe, like many of my friends, that travelling to the Moon and eventually to Mars and to other planets is a venture which we should undertake now, and I even believe that this project, in the long run, will contribute more to the solution of these grave problems we are facing here on Earth than many other potential projects of help which are debated and discussed year after year, and which are so extremely slow in yielding tangible results.

>Besides the need for new technologies, there is a continuing great need for new basic knowledge in the sciences if we wish to improve the conditions of human life on Earth. We need more knowledge in physics and chemistry, in biology and physiology, and very particularly in medicine to cope with all these problems which threaten man’s life: hunger, disease, contamination of food and water, pollution of the environment.

>Of all the many wonderful results of the space program so far, this picture may be the most important one. It opened our eyes to the fact that our Earth is a beautiful and most precious island in an unlimited void, and that there is no other place for us to live but the thin surface layer of our planet, bordered by the bleak nothingness of space. Never before did so many people recognize how limited our Earth really is, and how perilous it would be to tamper with its ecological balance. Ever since this picture was first published, voices have become louder and louder warning of the grave problems that confront man in our times: pollution, hunger, poverty, urban living, food production, water control, overpopulation. It is certainly not by accident that we begin to see the tremendous tasks waiting for us at a time when the young space age has provided us the first good look at our own planet.
John Watson might have said the same about the three-year-olds.
Ultimately, the main (or only) cost you have in a business is labor. Cutting costs means cutting the amount of work required to do something. If you invent a new technology which makes it faster to write or test code, then you need fewer people to achieve the same productivity.

Of course AI was about cutting jobs; you cannot cut costs without putting a dent in someone's employment somewhere. We should stop allowing people to lie about this and instead hold a percentage of their increased profitability accountable by taxing it and redirecting it to basic income.
you can go even faster by piping to \dev\null!

It's very performant.
And..? The details are really important here. I walked extensively in Snowdonia, the Lake District and the Peak District without poles but only carrying at most 3kg on my back. Distance covered in Britain tends to be less because the going is tough. 10 miles (16km) in the Peak District can be a very long day of walking. I then walked 320km across Northern Spain on the Camino Primitivo. Pack was more like 12-13kg and days were up to 32km with >2000m of elevation change day after day. Pretty much everyone who didn't have poles said they wished they had poles. It became something of a meme.
