I completely understand you're referring to FSF culture. I'm not referring to that. I've followed Richard Stallman for over 20 years.

Linux/BSD source code were part of a lineage that many of today's operating systems, whether you want to package that up as Mach, UMX, whatever.

1. Mac OS X includes oss code in it's foundation.

"Apple founder and CEO Steve Jobs once tried to hire Linus Torvalds, the irrepressible Finnish coder who created Linux and gave the thing its name.

But Torvalds said "No," and not long after that, Apple hired Jordan Hubbard, the creator of FreeBSD, a lesser known, but still thriving, open source operating system based on UNIX. It was a better fit: Mac OS X shares conceptual roots with Linux, but it shares honest-to-goodness code with FreeBSD." [1]

"The code at the heart of Mac OS X was born in the mid-1980s at NeXt Computer, the company Steve Jobs founded after his first stint at Apple. NeXt built a operating system based on two existing UNIX projects: Mach, from Carnegie Melon University, and BSD, created at the University of California at Berkeley. But on this base, they added their own, private code – such as the Cocoa programming framework and a graphical user interface – hoping to provide the sort of slick software environment pioneered by the Apple Macintosh." [1]

"Darwin, the core of Mac OS X, was open source and included quite a bit of code from FreeBSD." [1]

2. Android

"The Linux kernel is an extremely important part of the software on nearly every Android device. This section describes Linux kernel development and release models (below), stable and long-term supported (LTS) kernels (including why all Android devices should use stable releases instead of cherry picking patches), kernel configuration and hardening, requirements for interfaces and the modular kernels (introduced in Android O), kernel debugging and network testing, and SquashFS." [2]

"Android's history dates to 2003, when a team of California entrepreneurs launched Android, Inc. Their initial goal was to develop software for digital cameras. In 2005 Google acquired the company and put the team of Android, Inc. developers to work building an operating system for phones that was based on the Linux kernel and adaptations of some other open source utilities." [3]

I appreciate you feel the need to feel better about yourself at the expense of others by calling others names, but there's really no need, nor does it add to advancing any kind of understanding about the topic, except perhaps shining a light on jumping to myopic reactions and judgements of others.

I will not be replying to further messages from you on this thread for the above reason.

The original wording was "It's open source, but it's not free". It can be understood as "It's open source software, but the copies are sold for a fee" if you stick with the standard terms, and yes, it's pretty common, but the actual meaning here was "the source is available, but not under a FOSS license", and it's also not unusual (for example, license with commercial restrictions).

Even your comment is ambiguous. I'm not really sure whether you've understood the context (and I'm not sure I've understood you, either) due to the ambiguity. This is exactly why I said the phase "open source" is a misuse and it's important to stick with the standard terms.
Experts need to stop beginning sentences with the phrase “there is no evidence that” to encourage or discourage behavior.

When you’re dealing with a novel disease there’s not much randomized controlled evidence of anything so the best you can do is guess how situations work.

Rather than saying “there’s no evidence that” previous infection leads to immunity they could say “there are known diseases where recovery does not confer permanent immunity so don’t rely on that when creating policy”

Rather than say “there’s no evidence” that people have caught covid by touching their groceries and then touching their faces they could say “covid appears to spread by droplets and you should clean anything which might have come in contact with such droplets or wash your hands after every time you touch such things”

i’m of the opinion that weiner’s various housing bills, while lovely and worth passage in their own right, didn’t go far enough to break this construction gridlock in california.
I think it's the case that if you can get everyone in NY to completely isolate for a couple of months then the number of New Yorkers who are carriers can decline to a point where contact tracing makes sense.
Fear of change keeps you locked into misery. If at all possible take steps to get a new vision of your future and change careers, cos your current vision of your future is sounding pretty bleak (at least from your perspective).

If you need encouragement, try and find others stories of career change, and how they did it - there are plenty of them out there.... From https://www.ambisie.com/st/kerry-kitzelman :

"Some jobs can be like golden handcuffs. They pay well but you feel trapped by them. You are afraid to step out and make a change in case you wind up worse than before. Some jobs are like cardboard handcuffs, they pay nothing but you still allow yourself to be trapped by them because of fear of the unknown.

Making a decision to change may indeed result in your fears being realised, but facing that fear gives you the courage to overcome.

Since the day I decided to cut the umbilical cord to poorly paid employment, I have not been afraid to apply for any position I think I might enjoy and be rewarded for. It sometimes means steep learning curves and working harder than anyone else on your team, especially those that have the experience you don't. But the reward is that the world opens up to you. There is so much more opportunity than you could possibly have imagined."
> As for the math, there really is no other way to convince yourself that sin(x) and sin(2x) are orthogonal with respect to the product int(f,g,[0,2pi]) other than to try it out https://live.sympy.org/?evaluate=integrate(%20sin(x)*sin(2*x.... Try also with sin(3x) etc. and cos(n*x) etc.

I disagree with that. It's pretty easy to prove it in general by calculating \int_0^{2\pi} sin(mx)sin(nx) dx etc. for m ≠ n.
Genetics. I still have no intuition for how combining my wife’s and my DNA has resulted in children with traits from both of us. My brain always tries to imagine interleaving two binaries and hoping for a resulting program that works a bit like the two sources, which it of course wouldn’t.

"But zoning may be the real winner here. Japan’s zoning laws are national—so no local weirdness hampering construction and driving up prices. The system has 12 zones progressing from residential to commercial and industrial. Any buildings allowed in zone 1 are also allowed in the following zones. Basically: Housing can be built almost anywhere, even on extremely skinny or odd-sized parcels of land. This increases the amount of usable residential space and helps builders continue to meet demand, keeping housing costs under control. "

Fighting for something like this here will be one of the fights of the younger generations, otherwise they will be permanently locked out in any city with jobs. (There is plenty of housing where there are no jobs.)

Local NIMBY zoning must die. Its basically a cartel: collusion to restrict supply and drive prices artificially high.
The UK postcode system is not some magic hash that can resolve to a street name. Instead it’s a database maintained by Royal Mail that’s updated when a new postcode or street is created. This would explain why your sat-nav doesn’t know about newer addresses as its database hasn’t been updated.
If the LNT model was correct then you wouldn't need such a high level of precision, only a sample group with more radiation exposure (i.e. a medium level rather than low or high), so that the LNT model would predict that enough people would get cancer that it could actually be measured. If the people in those areas don't have an incidence of cancer which is linear with respect to the very high doses currently being used as the baseline then the LNT model is falsified.

The problem with this assumption is you can’t keep everything else identical. Population X and Y don’t grow up live and die in exactly identical areas expect for different radiation levels.

What you can do is control for as many factors as possible or use a proxy. It turns out skin cancer is a solid proxy, * and populations like Australia and skin cancer support the linear model down to the limits of our ability to detect it. But, then people want to suggest the non linear model kicks in as soon as the signal falls below the noise floor without evidence, even though that’s the same behavior in both models.

* As in you can detect population differences and work out whole body radiation dose equivalents.

PS: By this logic we should be operating under the assumption that the Greek Gods actually exist because the theory is very old and it is difficult to measure. People are promoting a new idea, not just trying to disprove an old one. Aka, Greek gods and the flying spaghetti monster have equal support. That’s absolutely fine, it’s saying some other untested theory is supported without evidence that’s at issue.
Letting Mardi gras happen in n.o. is the clear different choice from other places.
There's an experiment that transfers that angular momentum all the way up to macroscopic levels. By magnetizing a cylinder of iron, all the spins start pointing in the same direction. By conservation of angular momentum, the cylinder itself has to start spinning in the opposite direction. I'm very fond of this experiment, because it magnifies a strange quantum phenomenon to the classical level.

Spin being an intrinsically quantum mechanical concept, I'm afraid the microscopic mechanism by which that transfer occurs will only be explainable in a quantum mechanical context. Here it will appear as a term in the Hamiltonian coupling the spin of an electron to its motion in a potential.

Okay that's shitty. I've only ever worked Google (outside of retail + occasional side work) so I completely lack perspective on the wider tech industry. Generally I get the feeling I can balance work life pretty well here, though maybe at cost to career since there's always going to be people who don't, but I don't feel immediate pressure beyond that.

What's the situation like in smaller companies?

Does america have progressive or flat land taxes? Progressive land taxes (higher % tax of land value if you own more of it) make intuitive sense for housing affordability, but I read the Wikipedia[1] and only understood that 'it depends'.

Some of those queries are nonsense, but `select a, b from nums order by 2` is not one of them. `order by 2` here means "order by the second field in the select statement."
That's a good comic for an overview, but with a lot of assumptions. Like that Alice can limit what she reports, that 30 seconds or 5 minutes or any amount of time is a "contact" this is entirely undefined as far as I know, that Alice could be compelled to release this data (4th and 5th amendment cases possible), that there will likely be no open source alternatives to the centralized AppleGoogle plan where both will want to build into the OS, doesn't say that just because the "public data" was X that there isn't also meta data Y that a mfg could add and supplement (like GPS data) and just the whole idea of opt-out might be questionable now and impossible later.

It's a good idea to show how it could be privacy "OK" , but doesn't even hint on a reality that this might not be a road we want to go down - paved best intentions and all that.

Ah, how the wheel of life turns. Back before the Lost Decades ( https://en.wikipedia.org/wiki/Lost_Decade_(Japan) ), Japan was a completely different country.

"JAPAN'S 100-YEAR BANK LOANS (FORTUNE Magazine) By Susan Moffat May 21, 1990

"(FORTUNE Magazine) – The Japanese, famous for saving, are now loading their future generations with debt. Nippon Mortgage and Japan Housing Loan, two big home lenders, are offering 99- and 100-year multigeneration loans with interest rates from 8.9% to 9.9%. Borrowers put up their homes as collateral. Such deals represent sound fiscal planning for some families, especially the very wealthy living in Tokyo who, perversely, can almost not afford to inherit a house: Japan's graduated inheritance tax can take up to 70% of a family's assets, including its home. Under the 100-year loan plan, a second generation can move into a deceased parent's home and pay inheritance taxes on only a fraction of the house's value. Most Japanese, of course, don't have such problems. Their challenge is to find a house they can afford, especially if they want to live in Tokyo. The housing crunch there inspired Robinsons on the Sand, a 1989 hit movie that's now No. 8 on Japan's VCR rental list. It tells the story of a salaryman and his family, who are willing to do anything to escape the misery of their tiny rented apartment. The ''anything'' turns out to be living on constant display as a ''model family'' in a spacious model home while potential buyers tramp through. Jealous neighbors bully the children and make obscene phone calls. Before long, one of the two sons turns delinquent, the daughter is killing kittens, and the father ends up homeless in the street. Mom and the kids finally return to their old apartment, where they watch TV in the closet in blessed privacy. So much for that particular family's Japanese dream."

The 100-year Japanese residential mortgage: An examination

"A recent innovation in the Japanese real estate industry to promote home ownership is the creation of a 100-year mortgage term. The home, encumbered by the mortgage, becomes an ancestral property and is passed on from grandparent to grandchild in a multigenerational fashion. We analyze the implications of this innovative practice, contrast it with the conventional 30-year mortgage popular in Western nations and explore its unique benefits and limitations within the Japanese economic and cultural framework. Through the use of simulation, the conclusion is reached that the 100-year mortgage has failed to increase the affordability of homes. Instead, affluent homeowners are more likely to employ long-term mortgages as an estate-planning tool to reduce inheritance taxes."

I don’t get the privacy implications. Making a few assumptions here. Government can already get your location data and internet data from telco’s and Microsoft, your identity from bank purchases and social circle from fb/inferences from data. What’s left that a phone could provide, encrypted chat?

Coronavirus app is the least to worry about.
Had, not have. One fifth of New Yorker had the virus. (If that study is correct)

In other words, not all of those people that had a virus are currently infectious. Only the people that are currently actively infectious are the ones that need to be traced.
I agree. I've already written 1,000s of lines of code for this. I was trying to a) see if the problem had already been solved, b) see if it was worthwhile for me to continue trying to solve it.

The MS Power Query / BI tools come really close, but not quite.

As I like to say, they do the first 80%, but it's that last 80% that you still need :)
I can tell the design is ad-hoc. There is a science to manual writing, the author appears to be unaware of it (I guess by virtue of being born into an English speaking nation which afaict never saw fit to follow other ones who had already developed relevant standards in the 1960s). I see a couple improvements so that the proposal falls more in line with those standards:

1 should have an upstroke.

0 should have a loop, dot or stroke, not O.

q descender should have a stroke, not a loop.

9 should have a round bottom.

g descender should have a loop.

Latin letters should be written in script form, not block letter form, notably: ℰ, 𝒢, ℐ, 𝒥, ℒ, 𝒴, not E, G, I, J, L, Y.
You can get a large house that gets a lot of sun and is somewhat walkable / bikeable in Compton for $350k. With 20% down and all taxes & fees & insurance included, that's close to $1700/mo. In San Bernardino, you can get stuff for $250k, which about $1200/mo. You can get trailers in Riverside for $150k, which is about $730/mo.
> complicated and carefully orchestrated mechanisms

Yeah, I'd definitely second that. How could evolution result so quickly in something as "rudimentary" as Chlorella (i.e. the simplest plant). https://en.wikipedia.org/wiki/Chlorella
>If there is no vaccine, or if the vaccine isn't very good, social-distancing and contact-tracing is the only way to win.

Why is herd immunity not a "way we win"?

edit: Ah, yes, concern about the time to get there. Well, let's hope that happens quicker than expected (has any study not shown this?) because from where I'm sitting it looks like lock down is ending.
I am still not sold for NY. If you commute daily with the metro and test positive, even going back only one week, you are going to trigger hundreds of previous contacts (people in the same car in the train, on the platform, people you crossed walking in a tunnel, etc). Basically the average new yorker may end up having to get tested several times a week.

I think it makes more sense when the density of contacts is less extreme.

A core point of relativity is reference frames. From your perspective light in a vacuum always travels at c. The problem is that by special relativity, an observer moving at some speed relative to you will also see light traveling at c. This is a simple idea, but it causes a lot of very unintuitive effects. If we're being pedantic, relativity is very logical mathematically, but it's conceptually difficult because it flies in the face of how you think the world works.

Have a look at the simple inference example here: https://en.m.wikipedia.org/wiki/Time_dilation

Time doesn't necessarily slow down the further away you get from a clock. If you and a clock are both stationary (ie you're in the same inertial frame), you will observe it ticking in "normal" time, albeit delayed due to the distance. If the clock is moving relative to you however, you will measure its ticks to be slightly slower.

You may be confusing general relativistic effects which are distance dependent (as gravity weakens the further away you get).

If you carry a clock in your rocket, you will (in the rocket) measure it to tick once a second. When you get back to Earth, you'll find that it's lagged behind a clock that was started at the same time but was left on Earth.

Maybe have a look at simple wiki too https://simple.m.wikipedia.org/wiki/Special_relativity though it doesn't actually derive the Lorentz transforms unfortunately.

Ignore the gravity bit for now, that's general relativity and it's more complicated to explain.
I have to say that video completely changed the level of my understanding about it. Especially the bit of visually intuitively understanding why the imaginary terms are the integration of the wrapping of the frequency component. Well worth watching.

So I looked at these, I didn't notice any examples where the problem was with ANSI SQL? Please let me know if there were.

Speaking of which - I know Microsoft has Transact-SQL and Oracle has PL/SQL, is PostgreSQL just PostgreSQL?

What interesting controversial content are they banning specifically? Ethnonationalist propaganda?

I'm really annoyed by the common effect where people complaining about censorship on the big platforms always complain about it in vague abstract terms, because that gets a lot more support than complaining about people getting banned for targeted harassment or encouraging forcible removal of non-whites...

That article is utter trash of a smear piece - it isn't worthy of any word mincing. In contrast to normal advice I would say don't read it - it isn't worth your time. His demands are like grabbing a Med School Dean by the shoulders and shaking them while asking why they don't have a vaccine ready. That isn't their job and is literally demanding the impossible. It betrays a deep ignorance or attempted manipulation of expected ignorance among the audience that Silicon Valley are literal wizards. There are legitimate questions about shifting in industry and what lasting role start ups could play in a post Covid world but this is not that article. There is nothing reasonable to discuss.
