Every C++ programmer knows new and delete and how they work. At least it must be so. I sure as hell didn’t know all the theory and detail behind C++ memory management facilities until 3-4 years ago, and I’m obviously still learning the practical details. So, please bear with me and see if there are [...]
I hate to be just parroting XKCD, but I’m also unbelievably lazy and unimaginative so here it goes:
Just make sure you are having it minimize the cost!
Heed this warning Amiross!
I just realized that I’ve not posted anything technical in a long while. Here’s my effort to remedy the situation.
This is a modified version of the straightforward implementation of the “singleton” pattern (STFW yourself.)
Let me add this. I’m rather proud of this code, so I ask you please to give this code a read if [...]
This is definitely the coolest programming related text I’ve read in a long while: Church Encoding in Python. I even almost understood all of it!
I saw this on the Planet Python feed aggregation(?) (it is the second entry right now) which I got introduced to today.
But seriously, how cool is the CONS construction and [...]
Many C++ programmers see the keyword “const” as something redundant that only gets in the way. They curse Stroustrup and his ancestors each time they encounter a const-related compile error because of that view and fail to use it correctly quite often (note that I’m not saying that I’m not one of these people, but [...]
Just a quick one. Most of us have come to think of parentheses as sometimes necessary but always harmless little creatures. Our view is that unless parentheses change the order of evaluation (and therefore the meaning) of an expression, they are completely harmless.
Well, while that is true almost by definition, there are cases that we [...]
Metaprogramming can mean many things, but all of them can be made to (loosely) fit under the description of “writing programs that write or rather describe (a class of) other programs.” A classic and somewhat useless sample of this is writing a program that prints it’s own source code. My first real contact with this [...]
(UPDATE: Added the 6th item.)
I’m a fan of C/C++ preprocessor macros. I would be very happy if C++ received macros on par in power with those of Common Lisp macros, but that’s only a dream! We have to work with what we have.
Anyways, with use of macros come a lot of potential pitfalls. I’m going [...]
This is the long overdue package (and “ymeta” file,) containing KOPCS source code (verion 1.0.0 (codenamed Rincewind) build 1371.) The package also contains pre-built binaries mostly for Windows, but “Zero” is provided for 32-bit x86 Linux as well.
The package contains KOPCS (plus less-than-minimal documentation,) JFKOPCS scripts, yCrypto (plus documentation,) Zero, the web page templates, some [...]
There’s much fun to be had with C++ comments, and a lot of seriously usable tricks there as well. Of course, most of programmers already know all I could tell about the subject, but nonetheless, I think I’ll take a shot at bringing all the techniques I think might be useful together, and I might [...]
The Convex Hull code I posted earlier on this blog has a bug. When the points are all have the same X component, the implementation will misbehave. I may post a fix later; I’m off to work now, but I had meant to write and mention this for so long that when I remembered the [...]
I don’t know how do mathematicians define a Convex Hull, but informally, the (planar) convex hull of a set of point on the plain is defined as the smallest convex polygon that includes all the points.
If you think about it, the verteces of such polygon will have to be in the given set, and [...]
