How many bytes does an “int” have in c++?
Well, that depends on several things, like your current processor and compiler. The best way to know it, is by using the sizeof operator. Copy the following code, compile it and run it: #include <iostream> using namespace std; int main() { cout << “char: ” << sizeof(char) << endl; cout << “int: ” << sizeof(int) [...]

Hello everybody out there using minix -
I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones. This has been brewing since april, and is starting to get ready. I’d like any feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things).
I’ve currently ported bash(1.08) and gcc(1.40), and things seem to work. This implies that I’ll get something practical within a few months, and I’d like to know what features most people would want. Any suggestions are welcome, but I won’t promise I’ll implement them 
Linus (torvalds@kruuna.helsinki.fi)
PS. Yes – it’s free of any minix code, and it has a multi-threaded fs. It is NOT protable (uses 386 task switching etc), and it probably never will support anything other than AT-harddisks, as that’s all I have

How to redirect stderr to a file
Sometimes it is very useful to redirect the stderr (standard error output) to a file rather than to the screen. You can accomplish this right from the command line like this: myapp 2> error.log The previous line will redirect everything myapp sends to the stderr to a file named error.log. That is accomplished just by [...]
A simple Makefile
Learning how to create a Makefile is one of those tasks every C/C++ programmer has to do. Since there are many good make tutorials on the web, I’m only going to share a simplistic makefile that you can use for your projects. CFLAGS=-c -Wall -Iinclude LDFLAGS=-lPocoFoundation -lPocoData SOURCES=a.cpp b.cpp main.cpp OBJECTS=$(SOURCES:.cpp=.o) VPATH=src all: pre $(OBJECTS) [...]
