The only antidote to this kind of profiteering is a cultural shift. And if starts with us, the developers who are building this tech.

Unfortunately most of us are quite powerless to stop it otherwise. As time passes I'm only more convinced that this is an evil which will inevitably be abused by governments in the near future to target dissidents. And possibly other groups - you don't need much information from spending habits and location history to trivially build a profile consisting of religious affiliation, political affiliation, sexual orientation, and general interests. This maliciousness is putting us all at risk in the name of greed.
But will it run Multics?
(1) This gets a little into difficult notation but e.g. in Mathematica-style notation,

{{0,0},{1,0}} {{a},{b}} = {{0}, {a}}.

I think that you are preferring to left multiply your matrices by your points so that your points remain horizontal, whereas I am just used to my vectors being column vectors that I write as points sometimes? So that is why we are getting transposes of each other's notation.

(2) So the case for φ is very similar to the case for ε: you want to start with the constitutive relation, in this case φ² = φ + 1, to build the matrix with first column {{0},{1}} (multiplying 1 by φ gives φ) and the second column {{1},{1}} (the above constitutive relation).

The isomorphism is then that if X represents this adjoined unit then the point {{a}, {b}} becomes a I + b X one way [or say if you have a cubic constitutive relation then {{a},{b},{c}} becomes a I + b X + c X² similarly] and M becomes M {{1},{0}} [or say M {{1},{0},{0}} etc].

I would definitely agree that this is probably a much narrower statement than your
“if [a,b]M = [c,d], then (aI + bM)M = cI + dM” as the structure of X is very tight. It is always [e_2 e_3 ... e_n c] where e_i is a unit column vector with a 1 in the i’th place and 0s everywhere else, and c is the vector embodying the constitutive relation.

But if you want a condition, the isomorphism condition is probably the best place to go.

So the claim is that φ^n = F_{n-1} + F_n φ.
I would consider mass hysteria to be people duct taping their windows, standing in long lines outside of stores to try to get masks / hand sanitizer each morning, most people wearing masks all the time. I barely see 1 or 2 people with masks on on the subway every morning. I agree we are not at the point of "mass hysteria" right now.
Will check it out thanks, we had evaluated ABBYY but it didn't suit. Does your product do something like key value or table detection?
I can say for BigQuery and Databricks from personal experience.

BigQuery is much slower and is much more expensive for both storage and query.

Databricks (Spark) is even slower than that (both io and compute), although you can write custom code/use libs.

You seem to underestimate how heavily ClickHouse is optimized (e.g. compressed storage).
Look at /r/costco (for US) and you'll see the mild hysteria
> The kind of critical thinking that helps you prepare for things like this seems to be in short supply. Last week people thought I was silly for stocking up on dried goods and essentials, this week every store around me is sold out of hand sanitizer, clorox wipes, and isopropanol.

It is still silly to stock up things you will most probably not need, and if you do, can still get if people like you would not unnecessarily stock up on them.

IRC just isn't user-friendly to most internet users these days and its arcane prehistoric appearance is enough to spook them off to use something easier.

IRC still suffers from usability issues which WhatsApp, Slack, Discord and Telegram have already solved. However they are closed-source platforms, so Matrix is the best alternative for a truly free, open-source and more accessible platform for the general user to communicate from which should be IRCs successor.
It's nice when doing the right thing and self-interest align.
Or, you know, use PyGal or another server-side charting library: http://www.pygal.org/en/stable/

Is there much of a market for server-side rendering? I've been putzing around with a d3-inspired charting library in Rust mostly as a brain teaser though.
How low level? I make GoJS, a powerful diagramming library (the focus is more on diagrams and interactivity, than data). It's low level in that you can make a lot of different things with it, but higher level in that it has things like an undo manager.

Read to Fight Monsters: Using RL to teach agents to generalize to new settings
The "Unnatural" section here covers a few varieties of unnatural reverb effect [0]. (I'd also recommend many of the items with the "theory" tag on this blog)

In addition to those, reverbs that modulate the pitch signal are very common in music, but are physically impossible on a large scale. Most are subtle and create a detuned "thickening" sort of sound. Some will change the pitch by a whole octave or more. [1]

Artificial reverbs can also have their decay rates adjusted dynamically, and can even decay "negatively" so that the reverb actually grows in volume. Any other parameter could also be adjusted in real-time (depending on the reverb) [2]

It feels weird that there where nothing, then something exploded, and now I sit here on a rock, thinking about it.
The fraction of people needed to create herd immunity in a population is 1 - 1 / R0. With R0 at 4-7, that means about 75-86% of people within the population need to have COVID-19 antibodies before transmission naturally dies out through herd immunity. With current case numbers, China doesn't have anywhere close to this many cases - it would imply ~1B infections within the country rather than the ~80K that have been found so far, off by a factor of 10,000.

I think a likely outcome is that the current outbreak dies down, then it either flares up again from some undetected cases or is reintroduced from another country. But then, with the initial media attention elsewhere and COVID-19 symptoms basically looking like the flu, they'll just let the sick die rather than re-introduce draconian quarantine measures.
This statement generalizes quite well all around the world to the other kind of law, that's voted in parliament/congress... haha! ;-)

Nothing about any of the posted information is ambiguous. On the other hand, you decided to extract partial quotes that fit your narrative in a way to be purposefully deceptive.

This was beautiful to listen to. By pure luck (should have done more reading), I was visiting Pisa in Italy. There's a building (the baptistry) _beside_ the leaning tower, which has the most perfect acoustics.

Every hour, they close the doors and a person sings a series of individual notes which then interact just _beautifully_ in the building. Hard to describe. There's a soundcloud[1] here, not mine, stars properly around 1:23. I think you really have to be there though, it was wonderful.

On balance, I prefer this. Extra command flags neither pick my pocket nor break my leg.

The alternative (presuming the extra functionality is useful to someone, somewhere) would seem to be more standard commands, and that choice would use up more of the precious global namespace for small yet memorable lower-case command names.

I prefer as much of that as possible be reserved for userspace. I'll admit my mind boggles a bit when I ask myself what tar could possibly do with 139 flags, and it makes me a bit nervous about the surface area the program exposes.
That's actually pretty typical for behavioral science scatter plots. Getting p>.95 on a regression line is not something that is obvious from looking at the raw data.
An apology doesn't mean you took an action with bad intent; it indicates you recognize that some people were unhappy with the results of your action and that you care about those people.
What are the things that D3 did right to get the acclaim, and why does it keep it for so long?

d3 (especially now that they've broken the bits and bobs into discrete packages) takes a very unixy philosophy: do one thing and do it well. d3 lets you iterate over your data and get useful items back (e.g. scales that you can use to create geometric shapes for a chart). It's intimidating for some but offers a ton of flexibility you don't see with other charting libraries.

Mike Bostock also put a lot of effort into making sure that d3 lets you create beautiful charts.

Every other charting library I've seen takes a very different approach. Often enabling you to create ugly, inflexible charts.
The category is here to stay, regardless of which company is the first to make it stick. Probably better to give them the benefit of the doubt.

My guess is that d3 is too low-level to make reuse simple, and that using a higher-level abstraction would make the code more maintainable.
I've never heard of Moviefone - can anyone explain why a phone and dialup service is a "relic of the high-flying dotcom days"? Was there an internet component?

Snowflake doesn’t really keep up with Clickhouse (in my experience) and it costs money.

DataBricks is essentially Spark, and I shouldn’t need a whole spark cluster just to get database functionality. It also costs money.

Unless I’m mistaken, Presto is just a distributed query tool over the top of a separate storage layer, so that’s 2 things you have to setup.

I have no experience with BigQiery but I’ve heard good things about it and Redshift, however but if the rest of your infra isn’t on GCP/AWS then that will probably be a blocker.

Clickhouse is open source, comes with convenient clients in a bunch of languages as well as a HTTP API. It’s outrageously fast and has some cool features and makes the right trade-offs for its use-case, large range of supported input/output formats, built-in Kafka support and the replication and sharding is reasonably straightforward to setup.
It’s possibly about to be a demand shortage soon as well.
Professional developers mostly use Macs these days, and won't touch anything that doesn't have a nice UI that does exactly what they expect. Anything that looks too textual or "computer-code-y" that's not related to what they're working on, they will stay away from.

Case in point: virtually no one uses Emacs. Even Vim is diminishing; most devs now use Visual Studio Code.
>Sports commentators deal with hundreds of teams all the time, I don't see them mistaking the owner vs manager of a club

Sports commentators make mistakes on a regular basis, things like calling a defender a forward or mistaking a players name. They often correct themselves immediately or things move past it so quick nobody cares.

> - so they apparently want to claim they are not layperson

I took your use of the word "layperson" there to mean "not a professional in a field specialized in state politics." The authors of the site are professionals, just that doesn't prevent that mistake. Worded by me, but my point was that they are still normal error prone humans.
While this is fairly standard corporate finance framing, I don't think it's necessarily as true as it once was. If GE were to stop paying dividends and announce they were going to do buybacks funded by cheap debt, I doubt the market would more than shrug.
Social security?
WOW. I totally forgot this thing existed... I had the “3000” one in high school.

I remember it having a fantastic feel to it for being plastic. Other than that though, things like this were about having a system that you could write on without having to worry about battery life. Laptops were more expensive back then (oh man, I finally feel 31).

Currently to take notes in class, I use a 2008 MacBook Pro running Manjaro w/ i3wm. I try to copy the instructors talking points with shorthand.
My guess is that d3 is too low-level to make reuse simple, and that using a higher-level abstraction would make the code more maintainable.

In what context? It's not that hard to collect some scales and axes into a JS object, mix it with judicious use of CSS et voila.

I understand that d3 is low-level and verbose, but I can't say that I've any regret over deploying it in production.

Is it just me, or does this read like a hit piece on Lambda?

Disclosure: I’ve got two kids who are keen to consider Lambda post high school.

I don’t see ANY comparative balance.

If a student goes to university, and fails, using government backed student loans they owe non defaultable debt & accumulating interest.

If a student goes to university, and graduates, using government backed student loans they owe non defaultable debt & accumulating interest.

If a student goes to Lambda and fails, they owe nothing.

If a student goes to Lambda, passes, and can’t acquire a job paying above X, they owe nothing.

If a student goes to Lambda, passes, and acquires a job paying above Y, they owe Z.

I’m sure Lambda and other education providers using ISAS will face justified criticism, but the ”financialisation” of Higher education has become Stage 3-5 cancer.

At the end of the day, we pay for education to purchase a future salary.

Which education providers offer a money back guarantee?

And far more importantly, which ones don’t?
No problem!

It's too low level. For reference, I just re-implemented the entire thing in React. just react, with svg elements directly. Not using D3 at all. And it was roughly the same level of effort.

edit: saying that D3 was a terrible choice is not saying that D3 itself is terrible. D3 is amazing. But before choosing it, you should know exactly what it is, and whether it helps in your specific use case.
An aphorism being called a law is called a klysmism.
Get yourself a 4-color pen, or 4 separate pens, some highlighters, and in your own time (not in class), read the material from several sources - Wikipedia, text book, your professor's notes, understand the topic, then write your notes in your own words, using diagrams whenever possible.

Never copy things verbatim especially if you don't fully understand them. Understand the topic first, then write your notes.

If its taking you a long time to understand the topic, or it requires some back-tracking or further reading, do that, then return to the topic.

Taking down notes in lectures is often a waste of time because often the lecturer is just reading from his/her notes, which you have access to, however it depends on the Lecturer.

Final piece of advice is not to take them down in a text file. Use a pen and paper. I find hand-writing the notes is less distracting and forces me to think about them. However this may not be true for everyone.
