In my first job out from school I worked with a bunch of ex COBOL programmers who were re-writing the system in this new-fangled language called "C". One convention was that all "procedures" should be prefixed with a name indicating where t

ah thanks for answering the other questions I hadn't gotten around to asking (the reason why it's an orthonormal basis). I think I need to go home and have a play with this now!

This is a great explanation. The only thing that I still can't get my head around or visualize is how it is that we know that the set of all cos and sin functions is sufficient to span this set of "non-pathological" functions. So assuming

Don't forget that most people want to raise children some day. Sure maybe some solution could be made to work for single people, but for anyone in a family, you need space.

The problems start when you need to manage resources other than memory. Examples of things that require explicit clean up: -> Files -> Sockets -> Transactions The C++ resource model can be applied to all resources, not just memo

From my memories of statistics class: the way an actual statistician would try to answer this question would be to first describe a "null" hypothesis, called H0, then talk about the probability of seeing this set results, or an even more ex

Heh heh fair enough if you've heard it all before and it's only your own money that you are risking, all credit to you. That's great that your TSLA investment is doing so well! My mum bought me some BHP shares in the early 80s that are doin

Buying in the dips might give you a median positive return (95% of the time you'll come out ahead) - but your expected return can easily still be negative due to what happens the other 5% of the time. If you're following a very simple s

To present another side: I remember from reading Chuck Yeager's autobiography that Neil Armstrong was also a bit cocky and "know-it-all". However, I cannot find a quote of the passage online. I did find this interesting anecdote in which Ne

It is circular but still correct! There are many situations where there are feedback loops like this: For example: Male peacocks grow large tails because this is attractive to peahen mates. It's attractive to peahen mates because their ma

I voted it up because a) I'm interested in type theory and I like the idea of something that tries to explain it using C# rather than Haskell b) I wish HN had more of these sorts of articles as opposed to the usual startup/productivity/life

To my mind, Microsoft ought to be putting all of their corporate weight behind Mono. CLR, F#, C# are all technically superior to JVM, Scala and Java IMHO and many others. But what holds alot of people back from .Net in the enterprise is tha

As a hacker, for me, the best airline search website would be something that presents all available flights as a gigantic SQL table (or set of tables) so I could just type in a SQL query: select * from allflights f where start = 'London' an

Thanks a lot for sharing this - particularly the full source code of your implementation. It looks very clean and well written. I personally like that you wrote your own recursive descent parser and lexer rather than using some tool to gene

Ah I see. I've started implementing a Lisp interpreter in C# and I also was going along the path of making everything "first class" by using f-expressions where appropriate. So far my only actual f-expressions are "lambda" and "if" - everyt

I guess the alternative would be to define "apply" as a macro which evals the cons of its first argument and the other list of arguments...

To me it's because they provide a simple way to solve the hygiene problem in an interpreter. That is, it's easier to implement first-class macros (which allow hygiene) in an intepreter , than it is to implement scheme-style non-first-class

I first encountered the term "intron" when reading about Quines: http://www.madore.org/~david/computers/quine.html which made me wonder if "introns" in DNA are similar. After all, DNA can also be viewed as a "program" that prints its own

I'm not sure of Go's support for RAII... the key feature is the "composability" of the RAII technique. In C++, I can embedded a "socket" class as a member of some other object - on the stack or the heap - and it automatically and implicitly

For me, the killer feature of Rust is the support for RAII and explicit, deterministic memory management (if you want it). RAII and the ability to deterministically manage resources has always been C++'s killer feature IMHO. There have been
