I don't disagree with you at all. Segment your market. Focus on the most lucrative group first. When you have done all that, apply the usual tricks.

That all implies that there is such a lucrative group that has the expectation to pay a handsome sum for your product. It implies that there is no competition that has already driven the price into the ground.

If your product is truly novel and there is no competition, better set a higher price. You can always go lower and see how much more revenue you can get. Over time however, competition will show up and put the price closer to cost, or even below cost. Users will no longer expect to pay the older prices, so they won't - no matter how much value they get.
I mean, isn't it the same for T-Mobile/AT&T/Verizon?

I have accepted that most of my communications are going to be vulnerable to surveillance. I'd rather that surveillance come from large institutions that are reasonably equipped to manage their own vulnerabilities, and are easily watched and influenced by my own government. Better the devil you know than the devil you don't.

The one thing that freaked me out the most recently was when Google wrote to some Photos customers to tell them that their images and videos had been downloaded inadvertently by other customers.
`If the main frequency were a C on a piano, the overtone would be the next higher G—a perfect fifth, and the interval of the first two notes in the melody of Elvis Presley’s hit “I Can’t Help Falling in Love with You.”`

My read is that it's just saying that the first smaller frequency was the same ratio from the primary as G to C are in sound frequencies, so they're describing it as a similar interval as the first two notes, not as being literally the same tune.
The important thing about CC0 is that it’s an active declaration of permissivity that bypasses a bunch of the various public domain laws around the world. Just stating that something’s believed to be in the public domain is useful as a starting point but it’s not an explicit licence.

You are totally right.

I was thinking the IP address issue could be solved by adding a feature to crowdsource information about IP addresses from users, or maybe using APIs like ipinfo.io to create an updated database. (Didn't have time/money to implement it and wanted to avoid procrastinating the launch again and again...)

But unfortunately one just needs to create an account on Wikipedia (or use a VPN) to circumvent this kind of approach. This is really the main flaw, and I don't think there's a workaround to it.

Three points:

1. It is always going to be a little suspicious, at the very least, that the first COVID-19 outbreak happened in the same city as a virology institute. (Conversely, if we had a bizarre viral outbreak in Atlanta, I would have very similar suspicions.)

2. Nobody is going to start a war with China. On top of the centuries-old reasons that attacking China is stupid, they have nuclear weapons.

3. If it was released from a lab, it was almost certainly the result of an honest accident. SARS was very serious and China would have wanted to invest in research intended to prevent the kind of problems we are having now. If that research led to an accidental exposure and release of this virus, that would be a very cruel cosmic joke on us all, but it wouldn’t be a conspiracy for global domination or anything stupid like that.
I was hoping this would be an analysis of changes in usage patterns.

System identification may be easier (and privacy thus worse) now that the network topology is more static, as people move around less due to the virus.

This has been discussed in the responses to the tweets, but still couldn't find a definitive answer - why Basic?

I started with Basic too when I was a kid, but if I were to teach my child programming now in 2020, I would choose Python as a first language. It has many graphic tools, and it looks even more beginner-friendly than Basic.
C64 BASIC was the first language I learned which is probably true for lots and lots of other people. However, I learned it by reading the book that came with the computer and trying it out.

I cannot really imagine someone teaching me a programming language. Half the fun was trying to "get it". I think that if I had had someone teaching me BASIC back then, it would half felt like trying to solve a Sudoku with someone watching over your shoulder and telling you which numbers to put.

Leonard Cohen Interview (2001)

Not this BS again. For the nth time, the model of supply and demand you are familiar with depends on perfect competition, which involves transparency, substitutability, and frictionless entry and exit. When those conditions don't exist your idealized economic model will not operate efficiently and may not clear at all.

this is in every economics textbook and students are cautioned about differences between idealized models and real markets, but economic ideologues never seem to read that part.

It’s a great digest, I wouldn’t watch the talk but now I’m certainly more interested.

Added talk to the watch later list.
I expect my reply to be buried in the flood of others, but I enjoyed the essay because of the various responses it provokes internally:

1. Optimistic response.

Right on! More influential VCs need to beat the drum of rebuilding the American Dream and the manufacturing base in spite of there being less potential return than shoveling more money into ad tech. We clearly have the talent to build things again, what we need to work on now is the incentives for talented people to take long term risks instead of joining a FAANG or a hedge fund.

2. Cynical response.

The American Dream has absolutely been crushed. We need triage in the short term, not thought leaders writing about the wonderful opportunities ahead of us in rebuilding after the COVID crisis subsides. Those sitting on large amounts of capital should make mass donations to things like food banks across the country because there is a massive risk of millions of people falling into long term poverty in the immediate future. The short term must be about helping those in desperate need. Long term planning can come later.

3. Response as a father

I hope others read this essay and get inspired about taking more risks in building a better future. As for me, I’m a sole provider for my family and must focus my career on making enough money to support those that depend on me.

I could go on, but you get the idea. A good essay is thought provoking in spite of bits and pieces being easily criticizable.

This is typically the case that would benefit from a function compiled to webassembly. "Write once, run everywhere."

The protocol helper functions would be compiled to a webassembly library, and you would reuse them in Go, Python, the browser, etc

Of course, it's not justification for using their protocol (rewriting a protocol in another language is a good test for the protocol specification), but that would be a usecase for webassembly.

Some of them are quite nice but being a parent myself I don't subscribe to all of them. Which is expected, of course.

And then there are some tweets which are very situation/environment specific, like for instance the one about walking to school alone:

10 yo asked when I'd let him and his 7 yo brother walk to school by themselves. I told him the task was not to get himself to school safely, but to get his brother to school safely. I could practically hear his brain struggle to assimilate this paradigm shift.

All of my class mates and I walked to school alone from first class on (6 yrs of age) simply because we used to live in a smaller town where that was no problem. I'd even think that a parent driving their elementary school kids to school would have been looked at funny by the other parents.

Or this one:

Explained to nervous 7 yo that me being on the floor above is the same as me being in the next room, just rotated 90 degrees. After trying various objections, he had to agree.

While it might be true topologically, of course there are just practical every-day considerations why the are not exactly the same.

So, yeah, I find a lot of the tweets entertaining, but not as deeply insightful than some other commenters here.

It does saturate at some point, though. If you're turning patients away who are in need of ICU treatment (as some Italian hospitals were), your ICU admissions will be constant and equal to your rate of release from ICU, so it will appear that you've "flattened the curve" even if the number of sick people continues to grow exponentially.

It's much more likely those in Korea received false negative test results earlier on. Let's say that was the case, though, 116 out of 2.5 million rounds to zero and is of no practical consequence to herd immunity or the potential effectiveness of a vaccine.

You claim there is a trade-off between usability and performance for GPUs. The reason Rust is so popular is that people used to believe the same thing for CPU programming languages, yet Rust showed that you can have a language with the abstraction power and safety of Scala, Haskell, etc. and the performance of C. This was believed to be impossible, turns out it wasn't.

In the last NERSC survey, 75% of parallel models in use in US national HPC centers are MPI and/or OpenMP, ~22% is CUDA C and CUDA C++, and all others are the rest (~3%).

CUDA C++ is the best we have because it let's you write code that extracts all the performance from the device, while also allowing one to expose that code using very high-level APIs (Thrust, CUTLASS, CUB, AmgX, ...), and even RAPIDS, CuPY, etc.

While I think it is very useful to research how "high-level" a PL for GPUs can be (Futhark, Taichi), a practical language (that actually gets used widely on HPC) must do so without sacrificing low-levelness.

A GPU programming for the masses needs to provide or improve on the performance of CUDA C, its abstraction capabilities, and its safety.

While I think it is very useful to research how "high-level" a PL for GPUs can be (Futhark, Taichi), or how "middle" a middle ground can be (OpenCL, SyCL, etc.), a practical language that actually gets used widely on HPC must be better than what we have without sacrificing anything that we have.

The hardest thing about CUDA is writing code that uses the memory hierarchy well. In my experience, this is the hardest thing to do well portably, and the hardest thing to abstract, which is why pretty much all device-only high level libraries like CUB or CUTLASS expose the memory hierarchy on their APIs, and this is, at least today, required to get good performance.

I find languages like sequoia quite interesting, because they explore how to improve on this particular problem which, right now, it appears that any CUDA replacement would need to solve better than CUDA. Languages like regent/legion, hpx, futhark, taichi, etc. focus more on just trading off low-level performance for high-level abstractions. This research is definitely useful to explore what other things a CUDA killer could do better, but I don't think any of these would end up taking a little bit of CUDA's market share. At best, they might take a bit of OpenMP's marketshare, but that seems unlikely.

Isn't it sadistic the way Perl and Bash are so ideal for developers gaining control over their employers and ensuring job security by making themselves indispensable (forcing their employers to admit their impotence of firing them) by writing obscure unmaintainable code that only they can understand and modify?

You can do that in any language, of course, but Perl and Bash are are optimized for it.

While the other hand, Java is designed to appeal to management by making software developers fungible easily disposable worker-bees.

Lockdown was in effect 2 days before, starting with January 23rd, not "weeks before". Some people in Wuhan knew about the virus weeks or even months before this (start of December), that is correct.

Reading everything from an account will usually give you quite low signal to noise ratio. Even for someone like pg's timeline. I usually use min_retweets and min_faves filter of Twitter advanced search to get to the best (crowd-sourced) tweets by someone. For example -

> Meanwhile the NHS is covered in so much red tape that PPE and testing can't reach the frontline staff even when companies are trying to put them in their hands.

I don't think it's NHS red tape so much as the government being bloody incompetent. They think they can rule by decree and have that shower down helpfully on the minions. Nope, you've got to get your hands dirty. I'm not impressed.

Absolute freedom of speech is equally as detrimental to society as totalitarian government censorship. Propaganda, misinformation, and outright lies can convincingly be passed off as truth. The vast majority of the populace neither has the time, nor the inclination to properly vet, research, and confirm the information that is presented to them. Humans rarely acknowledge their own confirmation biases, which makes it trivial to manipulate the so called "marketplace of ideas". We're now beginning to see the myriad detrimental effects of an absolutist free speech society. Political troll bots manipulate opinions and sow discord. A huge slice of the United States relies on a reality warping "news" network that claims the right to fabricate falsehoods under the banner of free speech. Algorithms that feed users content send people down rabbit holes of extremist information fomenting groups of fervent believers in utter nonsense like "The Earth is flat", because the algorithms naively equate "engagement time" with value/truth.

Freedom of speech is a spectrum, and neither extreme of that spectrum is beneficial to a healthy society.
There most certainly was a reason, just not your reason (circumvention). Read the page you linked to. It literally says "users did not notice it", "users do not notice their absence", "users do not react as intended to positive or neutral security UI". It was user-focused. Not attacker-focused.

But I do agree it's pointless to keep continuing this.
