> After [I was an] undergrad at Yale, New York was a natural place to go, but I never worked there. It just felt like a place that was externally very pressurized. You had to conform to the external pressures that dictated your daily life. Your rent was $4,000 to $6,000 a month for craziness for like a walk-up in Hell’s Kitchen. Social structures were fairly set, like, you had to go to the Hamptons in the summer or something. There were these weird things that felt very dictated and you had to fit and you had to climb the pyramid schemes that people had established for you. Otherwise, you were out.

I feel this has more to do with being an undergrad at Yale (estimated living alumni ~170,000) than New York (population approaching 9 million at the heart of densely-populated region approaching the population of the whole of Australia).

I live in New York. I recognise the folks he describes. But I don't have to live in the same New York as they do or he feared doing. This isn't a small town where it is literally physically impossible to avoid encountering the same people every week.

New York gives you an endless canvas, but it's up to you to work out what kind of paint you are.

Carl Segan at the end of The Demon haunted World talks extensively about this mechanistic worldview, where animals were once thought of as clockwork.

I’d just note that your comment reads a bit like I endorse this view - whereas the intention of my post was to refute it. Perhaps you meant to reply to my parent?
We tried a few very large instance types to see if that made any difference, and provisioned IOPS did help, but everything was still slower than the EC2 DB and it cost a lot more on top of that.

> Control the media

This is a big one I think. From what I've read, in Vietnam, you just needed to get letter from your local newspaper accrediting you as a journalist, and you basically got a free ticket anywhere in Vietnam with the US military.

Now it's a lot harder to get embedded as a journalist with military units.

It’s so funny to me how Julia proponents often make it an ad hominem attack as if the writer hasn’t used the language. I’ve been using and following Julia closely since late 2012, and even attended a few meetups / talks at MIT about it since I was a grad student at the time, and even took a random matrices class with Alan Edelman in which he talked quite a bit about early julia.

Julia is by no means the only language to have patterns like this either, and in fact it’s not even a language where these patterns are particularly easy to use (I would reserve that for Haskell, but admit there may be other languages I don’t know which also make the cut — not julia though).

Your two ending paragraphs read to me like a super naive restatement of the company line memo for why these types of parametric abstractions are supposed to be good. It’s like a political platform, and just like a political platform it doesn’t keep its promise.

I have worked on projects where we needed to customize bit packing, not for cache performance, but for control over a modified version of sparse matrix types.

And I’m telling you the idea that we’d ever rely on the language’s chosen abstraction and do something like AbstractSparseMatrix{Float64} to pick up a bunch of interface properties “for free” while making the underlying logic specialized for our sparse format is crazy. It’s a naive false promise that grad students believe and it gets quickly beaten out of them in the real world once you realize how the type constraints and inheritance / type class extension constraints this places on you are too limiting and end up requiring just too much boilerplate that can’t quite be autogenerated because the way the abstract interface was chosen just doesn’t quite match your use case.

Finally you realize going down this road was the wrong idea all along, and you just write a super short implementation of MyCustomSparseMatrix or MyCustomCachePropertyMatrix in your case, and you fill in the logic manually that you thought you’d be clever by getting “for free” via plugging into some abstraction hierarchy, and often realize for your use case you don’t need to re-implement hardly any of it, and can do the boring parts pretty easily with converters or helper functions that marshal between whatever “for free” functionality you hoped to get and your simple custom not-parametric-abstraction type.

I’ve been down this road too many times, in many languages. I just leave it for the grad students who like playing with abstraction toys, and instead I just get back to actual work, solving problems economically, which warrants a super strong heuristic of avoiding this type of parametric abstraction pattern as much as possible.
loosing parts of your code is bad. The same goes for braces, if you loose them in a big c program your day is ruined as well.

1. Search through the highest-selling 100 apps in your favourite app store

2. Looks for apps which are poorly-rated (< 4 stars). These are apps which serves an actual need, but whose execution is lacking.

3. Build polished versions of those apps.
Great point. Let me rephrase this slightly to make it obvious that there is no contradiction between these two seemingly opposite pieces of advice. Do reinvent the wheel to solve your problems that you are then planning to sell to others. Do not reinvent the wheel to solve your problems that you are not planning to productize and for which you can easily get SaaS solutions. In other words, either create SaaS products, or use SaaS products. Don’t create one-off internal products that are not SaaS-able.

The global banking system is used by drastically more people than Bitcoin.

PostgreSQL is completely open-source with no backing company so everyone is reliant on some vendor if they want support. It makes no difference that Citus is one of them, with some core PG devs onboard.

Why would you talk about AWS RDS and then skip over Citus Cloud which is a managed service? If you consider this a fork then any plugin for PG is also a fork, which then makes it hard to have a productive discussion.
I have to be honest, I think entertainment may be one of those things where to some degree the sunk cost fallacy may not be 100% accurate. I mean yes, I see the reasoning behind this:

> We all do it. Ever gone to the cinema and stayed to the end of a film you actually loathed 10 minutes in – or watched yet another season of what was once your favourite TV show?

But TV shows, films, books, games... they've all got many examples of works which either start out terrible and get much better as they go along or start out fantastic and fall to pieces later down the line. Someone who takes this fallacy seriously all the time wouldn't read/watch Lord of the Rings long enough for the party to leave the shire. They probably wouldn't reach the first dungeon in The Legend of Zelda Twilight Princess (which is sometime after about 2 hours of tutorial content and meandering intros). Hell, TV Tropes has a whole list of works where you have to sit through hours of boring filler before getting to the interesting stuff:

https://tvtropes.org/pmwiki/pmwiki.php/Main/SlowPacedBeginni...

There's also the related idea of a show/work 'growing the beard', where it really picks up later on as the writers/actors/directors/whoever finally get into their stride.

So it's not necessarily a fallacy to sit through a tedious or even bad work under the assumption it'll get better, because in quite a few cases, that's exactly what does happen.
Do you mean the postgraduate science students? That is a good question, but I can say of science Ph.D students if you come with a scholarship from your home country and can fog a mirror then the Australian universities will accept you.

I should add that some of the best Ph.D students I have worked with were overseas students. It is not that all overseas students are bad, just that the bottom 25% are not capable of doing a Ph.D and yet we still give them a degree.
nah this is incorrect

what Jack Thompson proposed was an incredibly dumb and incorrect model where monkey see monkey do, and tried to blame mass shootings on videogames

he was rightly refuted, but refuting Jack Thompson doesn't imply refuting every single instance of media affecting behavior. crucially media can make some things that we would normally find shocking or outrage-inducing and demanding of correction, seem instead normal and acceptable. a classic example of this is how, in tandem with torture revelations of Abu-Grahib and Guantanamo Bay, we got a slew of media action heroes who used torture to achieve their ends.

24, Zero Dark Thirty, Grand Theft Auto, and even Zootopia all feature torture in various shapes and colors. Torture went from ineffective and "that evil thing that we won't stoop so low to do", to something that ballsy heroes must just do sometimes.

nobody who analyzes media seriously thinks it's unsurprising that the US is involved in like 8+ active military operations worldwide, while their videogame industry constantly features military themes and stories.

a simplistic mind would posit that the relationship only goes in one direction, an inquisitive one would realize that there's a reason why the US military is always lending equipment and resources to media creators who want verisimilitude in their works (so long as the message being pushed is agreeable to them).
People joke about fatuous "meaning of life" insights. But in my experience, you often do see "the big picture" of your life, and of everything. However, it's hard to remember stuff like that. And it fades pretty quickly, back into the slog of day-to-day life. I also got that from doing work with est/Landmark, NLP, Tony Robbins, etc. Not that they encourage the use of psychedelics ;)

This comment was probably specifically referring to universities specifically in the US.This is probably more specific to the US, where university was historically a means of socializing and networking for the sociopolitical elite and has since turned into an indicator of class or status. A lot of people are going into university because that's just what middle and upper class people do - a lack of a university education imparts a big cut in terms of status. Legislative requirements for degrees means that someone needs to study for 4 years (most of which will be on topics unrelated their job) otherwise they're locked out of employment options. People are forking over tens or hundreds of thousands of dollars mostly because society expects them to.

I think more and more people are realizing that the benefit of a university education isn't very good for the cost. Don't get me wrong, it is a positive return on investment, but it could probably be better structured as a vocational school for most people. If my parents didn't pay for my education, I probably would have tried doing a coding school and going directly into the workforce. I learned a lot of cool stuff in university, and attending a prestigious school opened up many opportunities. But most of the former was irrelevant to my job, and the latter is basically just an elaborate means of signalling status (which, while it definitely helped me I fundamentally don't think it'd be fair to hire a university grad simply for being a university grad if a non-grad as the same or better skills).

So racist AIs may be unfair to some people, but it doesn't matter because life is unfair?
No. What is "interesting" is the blatant disregard for facts because of the association that they have with race.

There is no question at this point that Chinese culture encourages cheating. It has been written about in media, it's all over Amazon, IP theft is a known issue, and it is ALL OVER universities. I regularly had Chinese students sitting in the back of class openly whispering during exams, while professors for some inane reason turned blind eyes. My anecdote is not unique.

Facts do not change simply by being denied, and the fact that a pattern of behavior is associated with a nationality or race does not mean it should be swept under the rug. Problems are only solved when they are identified.

>Would you ever make statements like "it's cultural acceptable for black community to condone it's cultural acceptable for black community to condone thefts and petty crimes, and politicians won't do anythign because it's inconvenient?

If statistics showed such, then yes, any sane person would say that. Also ironic that ignoring only negative cultural differences is a privileged Western affordance - our friends make no such mistakes in China and much of Asia, speaking as someone who lived in the region for years.
It's a lot more common in the wild than one thinks. Lions, tigers, wild dogs, alligators, fish, sharks, baboons, birds, hyenas, worms, bears, etc all eat animals that are still alive from time to time. Animals want to conserve as much enery as they can. As long as the prey is debilitated or not attracting other bigger predators, they'll eat it even if it is alive. Nature is really brutal when you get down to it.

> For example, how many people in North Carolina will be buying new consumer electronics this Christmas? Will it be fewer than normal, because they have to spend a lot of their own money cleaning up from a storm that was exasperating via climate change and had to deal with a government that made planning for climate change illegal? I think so.

It's entirely possible that more consumer electronics and home appliances will be purchased in North Carolina in Q4 this year, because so many were damaged in the flooding and will be repurchased out of necessity, coupled with some flood insurance money.

It still works. It just means, letting the deliveries go idle is cheaper than raising wages. For all their complaining, it doesn't sound like they're in a big hurry to get those shipments underway: "but for most of us, the resulting delays are mostly an inconvenience."

Typically employers will always complain about not finding cheaper labor. That doesn't necessarily mean there's a big enough problem. Once the problem becomes big enough, they will need to raise wages or find ways to automate it: eventually they'll do whatever is cheaper.

>You could start a QM book talking about the double slit experiment

That is indeed how my favorite QM book starts: Cohen-Tannoudji. See also Landau for one that starts from experiment and not theory.
> So actually the banks need deposits to hand out loans. What you are saying is that the deposits get a new label before handing them out as loans?

Well, no. What the BoE paper is saying is this: Suppose there are two banks, A and B.

If Bank A went on a lending spree without attracting new deposits (or otherwise bringing in new reserves), many of the deposits it created would end up with bank B, because bank A has no control over how its deposits are used. Bank A would have to transfer reserves to bank B to settle the transactions. Eventually bank A would run low on reserves and would need to raise more (by issuing debt, or by making its deposit rate more attractive).

But if bank B was going on a similar lending spree at the same time, the two banks wouldn't run down each others's reserves. If the two banks act in tandem (e.g. by getting caught up in speculative mortgage lending), they can create plenty of money without needing to attract new deposits.

The biggest regulatory hurdle that stops this happening is that there's a regulatory constraint on the leverage ratio (assets - liabilities) / assets.

> I much prefer the model where the mode of competition is economic benefit rather than "ability to be born in a good position”

Great! I also support economic competition as well as leveling the playing field by limiting the unfair advantages of being born in a good position.

Of course, as you probably know, social mobility is at historic lows in the US. This means people born into wealthy families are most likely to remain wealthy, and people born into poor families are most likely to remain poor. By your own argument, that is a problem because it shifts competition to “ability to be born in a good position”.

Therefore it seems that we agree after all!

Unless of course you’re not being intellectually honest and are using big words like “economic competition” only when it supports your pre-existing ideology.
Look for ones that turn blue when bruised.

Also, the fundamental methodology is to start with an extremely small amount. If there are no observable effects after some hours, eat double the amount. And repeat until there are clear effects, and decide if it's something useful. For food, for fun, or to use for poisoning enemies.

There is absolutely nothing special about "time-series" to be an actual type of database. It's all hype.

Time-series data is data that has a time component which is usually the primary property to query by. Almost every database can handle this, like MongoDB/Redis for lightweight use, Cassandra for write-heavy/global replication, ElasticSearch for raw search-style quering, or an OLAP columnstore (Redshift, MSSQL, Snowflake, Clickhouse) for serious ingest and querying. Monitoring systems like Prometheus and Netdata even have time-series storage built-in because it just isn't that hard.

InfluxDB is only really useful in the context of the integrations that it provides with the common monitoring software stacks. You can easily just create a regular relational table with "time" as a column and get great performance with an index, and then use partitioning to break up the table to get great performance over lots of data.

pg_partman is an extension that makes partitioning automatic. Timescale is an extension that makes time-focused partitioning automatic. Citus is an extension that makes partitioning across multiple nodes automatic. Or use one of the distributed OLAP systems mentioned above.

I’m not familiar with that book. I learnt QM from a 2-volume, 1500 pages book that gives you Schroedinger’s equation 10 pages in. But that book made no claim of being “introductory” and I previously had a “quantum physics” course including the different things that lead to Schroedinger’s equation (Plank, Rutherford, Bohr, etc).

In any case introductory books that discuss the physics and not just the mathematics do also exist, like vol 3 in Feynman’s lectures.

Edit: I’m looking at Griffiths’ book and after defining Schroedinger’s equation in section 1.1 he devotes three pages to discussing its statistical interpretation in section 1.2 and mentions different interpretations, the Bell inequalities and the measurement problem. He comes back to these philosophical issues at the end of the book in a 12-page afterword.
I work on large scale MCMC and causal inference problems. Would be very interested to know what this area of research is where you require abstract numeric types themselves to represent uncertainty, and why it would be different than other inference algorithms that handle uncertainty. I admit, at first blush I am extremely skeptical. It sounds like a silly sort of thing where instead of parameterizing over a numeric type, you might parameterize over a number-from-a-distribution type, and then try to make the type system represent how everything will flow in an MCMC setup, similar to tools like pymc, except where those are declarative and procedural, this would attempt to embed that into the type system. I can scarcely think of a worse way to represent manipulating uncertainty though. I hope I’m just reading your comment incorrectly.
