Python uses magic methods to work with objects in different ways, like handling arithmetic, comparisons, or string formatting.
And in this in-depth guide, Vivek explains what magic methods are and how they work.
You'll learn about object representation, operator overloading, container methods, attribute access, & lots more.

There is an issue compiling enblock.c with modern C compilers. a work around is using this version of the file:
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
void putint(int n)
{
char obuf[4];
obuf[0] = n % 256;
n /= 256;
obuf[1] = n % 256;
n /= 256;
obuf[2] = n % 256;
n /= 256;
obuf[3] = n % 256;
write(1, obuf, 4);
}
int main(int argc, char *argv[])
{
char *buf;
int c;
int bsize;
switch (argc) {
case 1:
bsize = 512;
break;
case 2:
bsize = atoi(argv[1]);
break;
default:
bsize = 0;
}
if (bsize == 0) {
fprintf(stderr, "usage: enblock [blocksize]\n");
return 1;
}
buf = malloc(bsize);
if (buf == NULL) {
fprintf(stderr, "error: malloc: %s\n", strerror(errno));
return 1;
}
while ((c = read(0, buf, bsize)) > 0) {
putint(bsize);
write(1, buf, bsize);
putint(bsize);
}
putint(0);
free(buf);
return 0;
}
I managed to run Unix 6 on SIMH (pdp11). It's great to experience that era, but the process of writing and compiling C code is tedious compared to what we have now.
Bill Labs has always impressed me with their groundbreaking contributions to tech and computer science. 💡
