To be fair, this person clearly said it was a "gut" feeling, and it is also ok to be wrong about things, since being corrected on saying a wrong thing is a wonderful way to learn.

Perhaps she knew that we would read her words, all of these centuries later, and see her for the bright, creative human being that she was. I hope she would take some solace knowing that we of the future see her condemnation as unjust, stup

You mean like some kind of organisation designed to regulate the behaviours of businesses and individuals over the long term such that the general population isn't exploited or abused by the few, and tragedy of the commons style proble

They're a freight-forwarder branding themselves as a software company, competing with the likes of DHL, DSV and 100s of other smaller organisations. In short, they have a very viable business model, but freight forwarding is a cut-thro

This is not generally the case. Practically speaking, big O notation is almost always bounded. The clojure vector implementation has a maximum count of 2^32, therefore the behaviour at infinity is O(SomeException)
186.
by ludston 3y ago
You know this would mean that a change to a vector under 32 elements is O(n) right? (Which it isn't quite in all cases, because the actual implementation is a bit more complex) But this doesn't apply to hashset because hashmaps ar

An order of magnitude is not necessarily a factor of 10. Otherwise we would always just say, "factor of 10" which has fewer syllables. The difference between O(logn) to O(1) is often referred to as an order of magnitude. As is O(l
188.
by ludston 3y ago
To drill down into this, adding or removing from a vector or hashset in clojure is O(logn). This also means that random access is also O(logn). Most operations on clojure persistent data structures are an order of magnitude less efficient t

It's referring to metaprogramming. Lots of large programs end up full of DSLs and config files with bespoke parsers and code generators, which are largely inferior (in that they are bloated, bespoke and less expressive) to the metaprog

You explicitly said logging is a form of "unit test" which has a very specific meaning and a log is not it. Observing a log can obviously be part of an assertion in a test be it manual or whatever, but an assertion is not a unit
191.
by ludston 3y ago
A log statement isn't a unit test in the same way that apples aren't trees. A unit test is a discrete, runnable program that asserts some state about your program to be true, whereas a log is just some subsystem of your overall pr

What about the author though? You didn't mention them at all.

That's not immutability, that's "log shipping". And if an organisation doesn't have the capability to delete personal data from it's backups, and it operates in Europe, chances are that it's in violation o

GDPR and the right to having your personal data deleted certainly puts a bit of a stopper on using an immutable database for anything personally identifying.

Realistically yes. But I would still use it.

The wisdom of, "private sector is more efficient than government" only applies when there are market incentives for efficiency: Specifically, there must be competing private businesses to lower costs, and the market consumers must

Except healthcare. That's loads better when the government does it. Roads too. And water supply? Realistically all things that are natural monopolies seem to do better under democratic governance.

There is ample opportunity to strawman the advice in this book and invent scenarios where it does not apply. I'd say that it is something of a cultural phenomenon of our times that we get these angry criticisms of opinions rather than

That's your opinion. I'd really much prefer another Mozart.

It's never too late to learn the meaning of a new word. Why just yesterday I was reading The Count of Monte Cristo, where the author used "felicity" in a context I'd not seen before. Fortunately in my very pocket was a p

You see wind instruments outside of orchestras all the time though. The main reason for the domination of guitar and piano is economic: you can play more notes at once and therefore have played richer sound with fewer players. You can split

Firstly because it makes me laugh, but also it's because it's actually gatekeeping other people's language that is excluding and antisocial. I firmly believe that we ought to accept the language that others use when the speak

I enjoy collecting little things like this to annoy the grammar gatekeepers. Why say "regardless" when "irregardless" means the same thing but also annoys prescriptivists? "Ironical" instead of "ironic&quo

Playing with a capo sounds different to playing without one, and digital keyboards don't sound the same as acoustic instruments. Sure you might make a career as a musician playing everything by ear, and there is nothing wrong with that

It's bizarre. It's certainly possible to do this but there isn't much point given the different instruments need different fingering tequniques to reach notes anyway, and getting a feel for these fingerings ought to be harder
