If I asked you to divide an apple by a stone, what would your answer be? Infinity is simply not a thing that your carefully-honed real-world intuitions about division apply to. Hilbert's hotel is precisely a thought experiment to prove this: divide an infinitely large set among infinitely many people, and you can get many different results. Any true statement about infinities you construct with division is true only by coincidence, not for the usual maths reason that things are true (namely that they are the result of following some broadly-applicable rules).

There is no number called "infinity", so there's no reason to expect the rules of the arithmetic of numbers to apply to it; you have to carefully go and prove that the rules you want to apply have some meaning when you extend the language in this way, and moreover that these rules are true. For example, there are multiple meaningful ways to add infinite quantities, e.g. depending on whether you are considering the cardinals or the ordinals. Those concepts are the same in finite-land, but are different in infinite-land. Cardinals do not admit the notion of "division"; ordinals at least have the division algorithm.

Yes but batteries contain toxic materials and rare earth minerals, require lots of energy to make, lots of energy to recycle, etc...

So energy to mine the materials, energy to assemble the battery, energy to recycle the battery after it's useful lifespan (5-10 years)... None of these are ever counted in people's calculations. I tried to find data on energy required to produce the batteries and they still didn't count the mining cost.

I'd wager that hydrogen is more energy efficient over the entire lifespan of a vehicle.

This is often deliberate. Postponing payment of invoices means you have at any given time a larger warchest to invest and gain an edge, or conversely have to pay more interest. CFOs often set a target and push back on swift payments. Some companies even risk lawsuits to be able to not pay the bill just yet, though it obviously depends on context what you can get away with and what harms your reputation too much.
100% agree, if you're 100% utilized than you're working for your business not on your business.

I have three other pieces of advice.

One you need to decide whether you want to run a consultancy or be a consultant. The first means scaling by hiring more people the second means scaling by increasing your rate. You can make more money doing the first but your job will eventually be 100% account management and sales.

The second piece of advice is you need to come up with a business plan. The most important part of this is an actual plan for predictably acquiring new customers.

Third general piece of advice is 98% of the time being a general software consulting company is a shitty business. A good first step is pick a specific problem and/or a specific industry. "We build custom CRMs for enterprise sales organizations.", "we do custom ERP work for Oil & Gas" or "We help startups scale Postgres databases" are all much better businesses than "we write software". This is for two reasons. One you have a specific product you're selling to a specific customer which will help immensely with sales/marketing. Two the margins are much better.

Where in the guidelines does it mention that one cannot say 'tech bro, finance bro, pharma bro, and more recently and most actively the crypto bro'? These have been there for years despite the guidelines existing.

Me saying 'AI bros' is no different. Given it is fine to mention the tech bros, finance bros, crypto bros and the other, then it is also fine to say 'AI bros'.
Moreover, there cannot be a constructive proof using this construction, because the Banach-Tarski construction will fail if all sets are measurable (which can happen in the absence of Choice). A constructive proof would continue to succeed in such settings.
In the past many things have been considered a serius threat fo Google monopoly:

Of all this threat chatgpt is probably the least dangerous because there is no way to always get a correct aswer (or the better answer internet can offer).
> Mathematics need not directly model the 'real' world or match our physical intuition

There's so many other ways to demonstrate this. For example, it's possible to map the integers to the rational numbers one-to-one, which is a good definition for "as many as" when dealing with infinite sets, even though there are infinitely many rational numbers between any two rational numbers. Moreover, there are as many integer multiples of a trillion as there are integers total.

This is to do with set cardinality:

https://en.wikipedia.org/wiki/Cardinality

... which again comes back to the axiom of choice:

> If the axiom of choice holds, the law of trichotomy holds for cardinality. Thus we can make the following definitions:

> * Any set X with cardinality less than that of the natural numbers [...] is said to be a finite set.

> * Any set X that has the same cardinality as the set of the natural numbers [...] is said to be a countably infinite set.[10]

> * Any set X with cardinality greater than that of the natural numbers [...] is said to be uncountable.

HP sold an official IOS version of the 15C for years but stopped updating it at some point. It still worked but didn't scale correctly on new iPhones. About a year ago I noticed that it had updated. It looks like they sold it to "Royal Consumer Products" aka hpofficesupply.com which is a licensee selling HP-branded (physical) calculators. It rotates between landscape and portrait mode and includes a full manual.
LLVM? Yes. Clang? No.

The front-end compiler and standard library are written from scratch, but it uses LLVM as the backend. The standard library is not yet complete, but it's amazing how it uses Circle's unique features to implement in a very elegant and efficient manner certain classes like variant and tuple which are absolute monstrosities of complexity in clang/g++/MSVC.

At least in 2019, it was possible. The GUI connects to the daemon through a TCP socket, and all info passed through that connection (no direct file access from the GUI). It was possible to set it up with the daemon on one machine, and the GUI on another -- though I vaguely remember having to set up an SSH tunnel so that the connection would come from 127.0.0.1 on the daemon machine (not sure it was needed, but I think that's how I set it up).

I feel that the main thing I got from the book is that it made me settle and accept that there is no truth to be had. That the main narratives are much less truthy than I expected. There really is much more diversity in how humans were structured than we can phantom, or reliably reconstruct from the evidence. That is why having a wider spectrum of narratives is more important if you want to learn from the past.

While I knew many of the points and facts in the book, somehow that realization had never stuck before.

History was written be the victors, pre-history even more so. The first chapters have a good point, which gets clearer later on in the book. Much of the historic narrative has been coloured by the way Eurasia thinks in the last 500 years.

And it is stuff I kind of knew or suspected, now I really internalised the idea because of the book. The main idea is obvious in retrospect.

Half the time, it's simply a result of relying on C's built in math (which pretty much translates to what your native ALU can do). I'm sure, as you allude to, the notion of doing more complicated and precise calculations is not normally considered.

It is similar to what happens with teachers where I come from. Once you managed to obtain the status of "teacher", it is virtually impossible to loose it again, no matter how bad your teaching is. Apparently, something similar is going on with scientists, and a few other professions. There is no mechanism in place to get rid of bad apples, because society thinks it would be unfair to remove someone from a job where they had to go thru considerable training to actually get it.

So, Intel would be split into ~2400 50-person companies. Coordination of those, through contracts, threats and lawsuits would be nightmare. A basic economic theory ("theory of the firm") says that large companies are created, because they decrease the friction that exists when many small companies (or even just individuals) cooperate to achieve a large and complex thing.
One that stuck with me was Ep 86: The LinkedIn Incident. It is about how one seemingly inconsequential device at home being compromised can lead to a massive data breach.
>...we have the idea that the unit cube [0,1]³ should have a finite volume of exactly 1...

>...even though it contains infinitely many points.

There is the division by infinity.

Cut the volume in half. Still has infinite points. infinity/2 = infinity.

1 = 1/2, or 1=2 if you can cancel those.

Any set of points is some number of points 1,2, ..infinity. Points are infinitely small (division by infinity) so you'd have to infinitely many of them to have a volume other than zero. And you're back to infinity points * (1/infinity) vol of a point.

So yeah, no way I can see to have any set of points have a well defined volume because the volume of a point is a division by infinity, unless the set is finite in which case it is zero (or whatever you define a finite number divided infinitely to be - define it to be gerald if that helps? - Mathematical immaturity on display right there).
How to periodically sync a Git repository with its remote
Never heard of him before, and I can't tell if he's a crackpot or going to invent the next big thing or both.

It seems like his whole thing is allowing people to access new thoughts that they couldn't before.

I'm not really familiar with that kind of almost psychonautic inspired approach to programming, so I don't really have a good understanding of his vision. But it seems like a few tools have parts of his vision.

FORTH is famous for small programs that almost redefine the language itself and can say a lot in less than a page. Seems very relevant, but I don't know anything about it besides the basic outline and history.

LISP seems to have some of the same characteristics. Maybe a live code environment for FORTH would be of interest?

I'd argue Excel and co are probably the biggest success in live general purpose data manipulation, and probably the only ones out there I actually have any interest in.

Spreadsheets are also an amazing example of something uniquely digital, that's not quite just a paper emulator, and isn't just some crazy impractical experiment.

Spreadsheets are pretty amazing when you think about it.

Really the big thing that makes them special is the idea that you can put an =expression wherever you could put a value, embedded in a normal, consumery app that otherwise works similar to other software.

The other thing that makes it special is that it's highly constrained. You get a 2D grid of cells. Creativity loves constraint and they seem to have the perfect amount.

It seems average users are perfectly capable of cramming their use case into a set of high level primitives. That's different from almost every other "Code for everyone" system that just tries to make low level primitives accessible.

It's easier to use the wrong framework to do something than build the right thing with raw materials.

From that people who are not programmers at all run half the financial system. And it works. The world has not exploded.

It might be almost never the ideal choice, but then again, I don't think any DIY programming is likely the ideal choice when off the shelf special purpose apps exist, I'd never suggest anyone but a megacorp do their own booking and billing app or something.

I can't think of a single other tool that lets people who would never program, and hate programming... write programs. All the other tools are just things an average person could learn. But they won't, because they'll wonder why. And they'll be right, because they probably don't want to spend enough time with it to be able to do anything they couldn't do in a Google Sheet.

Not only that, it's a live environment that's truly practical, it's not just a tool for thinking, it's a tool for a subset of the same stuff Python might do.

It's something I use on occasion, and frequently use =expressions in other contexts.

It might not be truly general purpose, but it sure is impressive.
A few points, female fertility declines steeply past 40, but males not so much, so older males could conceivably father children with other females.

Dare I say it, and this may just be not right, Genghis Khan is purportedly supposed to have fathered thousands of children it is said he had 500 or so secondary wives (citation needed).

Since average (mean) income is famously a bit pointless due to a few very rich people, wouldn’t father’s age at conception be similarly effected?
Good list but curious why you advise against doing conferences and conventions. The obvious benefit in my mind is advertising, potential clients, and most importantly, advertisable "credibility" on your website in the form of "Speaker at X conf".

I'm not in the consulting business, however, and the list of benefits is speculative.
> who are agnostic or atheist and can't lean on concepts like "The Buddha" or "Lord Shiva" (although I myself am Hindu.)

Whoever can accept the Gödel's incompleteness theorems and still use math, doesn't mind games, simulations and usage of different dimensionalities and topologies, also can practice both visual and sensory imagination - is perfectly capable of believing in Buddha, Shiva, whoever and whatever for the duration of the exercise if they chose to. Blieving in a diety with certain characteristics, an embodiment of certain archetypes/feelings/intentions during the practice can do night-and-day difference in efficiency and precision of intentional nervous system regulation.
> Buffalo buffalo buffalo Buffalo buffalo, is hard to parse because English is very expressive. And you kinda have to know words have different meaning in different context. If I explain buffalo is another word for bison, and also buffalo means coerce, I can rephrase this

> Bison from Buffalo coerce other Bison from Buffalo.

The words don't have different meanings, though, at least in idiomatic English. No-one uses the word "buffalo" to mean "coerce". I'd be surprised if you could find even a handful of examples of it being used that way.

File the "many buffalos" thing under the same heading as the "code golf / obfuscated C" type things where you've got a chain of half a dozen ternary operators wrapped in a loop to make a state machine, where a switch() statement would suffice.
What is your stack and what libraries are you using?
I never did any paid advertising. At this point it's roughly 80% organic algorithmic platform trafic and 20% word-of-mouth. The latter includes outside user-driven platforms, like MiniReview and TapTap.

I used to do guerilla marketting a bunch, mostly on Reddit, certainly a lot before and around release. I got some ok youtuber and streamer coverage around this time. Ended up releasing on Steam with 10k wishlists, which was enough to provide an initial visibility boost.

Soon before releasing on mobile, I participated in the Humble Stand with Ukraine Bundle, where I distributed 200k+ free keys for charity. Marketing value wasn't what was on my mind at the time, but I know quite a lot of people who picked up the bundle tried out the game, thought "neat but I'd prefer to play this on mobile", and then helped to drive a lot of initial traffic and get picked up by the algo.

I also got featured a bunch in both Google's an Apple's curated game collections.
The stack contains states, not symbols. A shifted state encodes the shifted terminal PLUS the information what nonterminals that terminal can be part of (in LR(1), each of those nonterminals is augmented with its accepted follow-set).

Really the only place where the above breaks down is when in the middle of a rule, after shifting a terminal (or "shifting" a nonterminal after reduction; this is called differently in literature but it really behaves like shifting nonterminals) all that context information is dropped under the assumption that it is not needed for the current rule, but is still available deeper on the stack and will resurface after reducing the current rule. At that point, an error would be missing this information.
We know that we don't know virtually anything about ancient history, but yet we still believe that our completely flawed (and often made up) theories must be "challenged" by an insurmountable amount of indisputable evidence.

It is not necessary.

I'm reading the book right now, I'm not an English native speaker so I'm being a bit slow, but I've watched several videos about it (that's how I knew about the book, thanks YouTube) and the first thing that got me excited was that, for the first time since I remember, this theory is not patronizing towards ancient civilizations.

All our building blocks are based on the concept "they couldn't possibly be capable of", while it is now evident that not only they could, but they did.

The second thing I liked about Wengrow was that he acknowledges that questions such as "was there an advanced civilization before the Sumerians?" are legitimate questions, historians and archeologists should embrace that mentality and answer the questions, not try to disprove wild theories proposed by amateurs and sometimes plain crooks. It doesn't necessarily follow that it was the aliens of course, but, AFAICR, at school they taught me that "it was impossible", not that we don't know, but that humans were, in layman terms, "too stupid to even think about it" and in the end the unanswered questions, the fact that people see that the evidence do not add up, lead to the success of people like Graham Hancock, instead of leading people to trusting the hard work on the field of historians and archeologists. It's a vicious circle that I hope this book will break.
