Experiencing Tech as a Professional Techie

Have I appropriately professed my love for Ruby yet?

I used to play around with Ruby a lot. Here’s another script, where I was downloading fedora ISOs and giving myself feedback as to the progress of the operation (yes, I was in cygwin also).#!/usr/bin/rubyrequire ‘net/ftp’require ‘fileutils’ftp=Net::FTP.new("ftp.linux.ncsu.edu")ftp.login("anonymous", "me@email.com")FileUtils.chdir("/cygdrive/c/downloads/fedora")files=ftp.chdir("pub/fedora/linux/core/3/i386/iso")def mecallback() print ‘filename: ‘, (File.size($fileName) * 100.0 / $fileSize), "%\n"end$fileName="FC3-i386-disc3.iso"$fileSize=ftp.size($fileName)print ‘filename: ‘, $fileName, "\n"ftp.getbinaryfile($fileName, $fileName, 2**20) { [...]

Ruby is so elegant

This is a script to log in to a server via Telnet and run a single script remotely.require ‘net/telnet.rb’myserver.com = Net::Telnet::new("Host" => "myserver.com", "Timeout" => 30, "Prompt" => /[$%#] \z/n)myserver.com.login("username", "password") { |c| print c }myserver.com.closemyserver.com.cmd("./check_missing.sh") { |c| print c }

.htaccess redirect guide

My favorite tip: Changed file extension?This example is perfect if you’ve decided to switch to .php from .html pages. It will look for any .html page and redirect it to .php (ie http://www.example.com/yourpage.html and redirect it to http://www.example.com/yourpage.php). Now, be careful with this, it does mean any html page. I did this on one of [...]

Optimized prime number generator

Same specs as previous system, 8 hours to find all primes to ULONG_MAX.#include <stdio.h>#include <malloc.h>#include <limits.h>#include <math.h>struct linked_list{ unsigned long number; struct linked_list *next;};int main(int argc, char **argv){ unsigned long divisor, max_divisor, prime_test; unsigned long max_prime_to_store; struct linked_list *first=NULL, *current=NULL, *last=NULL; first=(struct linked_list *)malloc(sizeof(struct linked_list)); first->number = 2L; first->next = NULL; last = first; printf("%lu\n", [...]

I miss C programming. Program to find prime numbers

Uses unsigned long long, goes up to ULONG_LONG_MAX.Intel Core Duo 2 processor, running Cygwin on Windows XP, and compiled using gcc 3.4.4. Stops at first million results due to time. Can reasonably get to 10 million, if you’re willing to wait.#include <stdio.h>#include <math.h>#include <limits.h>int main(int argc, char **argv){ unsigned long long divisor, max_divisor, prime_test; int [...]
