Git is probably the most notable example of a complex software program that is composed of a series of independant tools, though gcc is actually also architecturally a pipeline. Visual studio code might also not be a great example. It&#x2

I mean, the lamdbda calculus doesn't allow you to define a function!

Maybe? it depends how you use them... any asynchronous operation will require memory, and that memory has to go somewhere. In CPS it goes on the heap... in the threaded style you have a stack you can put it on. This probably will waste s

I'm not sure this is true. Sure the syntax of the lanuage is simple, but smalltalk is useless with just its syntax (it doesn't even have ifs or loops!). You only have a real smalltalk with a class hierarchy defined, and then sud

Also lisp isn't actually based on the lambda calculus (for one thing the lamdba calculus doesn't have recursion!! (besides through the Y combinator). Lisp is also evaluated in a very different way than the lamdbda calculus. Lisp

That's the real problem with the studies saying homework does nothing. Drill does improve learning! But that's not showing up in these studies for some reason...

I agree! Also "prepare for the workplace" is meaningless. There are many many different kinds of workplaces!

There are a finite number of school hours! Teachers have to be paid! That being said, America is extremely unusual in the small number of explicit classroom hours students have, and the large amount of homework students are expected to do.

The problem is that exams are often an extremely poor assessment of actual student learning, since they're such an unnatural format (no checking of oneself, strong time limits, extremely "easy" problems that can be done in th

School really doesn't mimic the workplace very well. For one thing, work doesn't usually give homework! (with some exceptions like the law). Docking students for bad behavior is problematic, because it requires the teacher to be

ARM assembly is easy to learn, because of its relatively small and orthogonal instruction set. However, load store architectures are annoying to program in, since you're constantly having to juggle memory. The lack of a convenient wa

What's more important are multiple readable entries for an object! And for those objects not to disapear unless the ref count on them is zero. The quintessential example is a library... By linking it into a directory the program has

Spivak is brutal. But's its powerful medicine. There's a reason why the U of C can have large numbers of students take real analysis in their second year! Getting through spivak makes analysis much much easier

You can rephrase that conjecture to say... given any sequence of digits not ending in 2 (or 0), is there a prime number that ends in that sequence. That's an interesting conjecture!

Fortran didn't originally have pointers, and pointer based code is relatively rare in fortran, so making requirements about pointer aliasing doesn't have same potential to completely break your code that it does in c. The reason

Given how many people argue the dumbest things about this article (like that if we include the January 2020 Covid numbers things would be differrent!) I don't think the issue is intentional stupidity. The journalist has a story, and i

This is one of those canards that people who've never actually programmed in Algol or old lisps (or who forget what its like!) say. The thing to remember about Algol 60 is that it does not have nominal types! It only has (fixed) nume

That's not really true. The insanity plea has existed in the common law at least since the 13th century, though like many affirmative defences including self-defense, it was a reason for pardon, and not a reason for acquittal. The M&

This isn't actually a problem! We build gas pipelines all the time which suffer exactly the same problem. (and no, you don't want gas pipelines to leak!) You can use expansion joints, or grooved couplings that enable movement, a

It literally quotes the Azhvars... you're right about Malva, that was a mistake. I don't agree with a possible assamese origin of either Kumarila or Dharmakirti, and see no reason to doubt Taranatha, and in the 9th century, the d
