File Transfer Protocol

Post date: April 12, 2005, 18:04 Category: Network Views: 2372 Comments
Tutorial quote: Wake up, you goodness-to-GUI slacksters! It's time to get up and get out of that hammock and put your feet on the ground and your hands on the CLI. This week we're going to talk about data in motion. Taking a file from one place on the network. Putting it someplace else. Most often today some form of FTP, the File Transfer Protocol, is used to do those things. It's been part of the Internet since there was an Internet.

Post date: May 9, 2007, 22:05 Category: Installing Views: 6623 Comments
Tutorial quote: This tutorial will guide you through the installation and configuration of Lintrack, a GNU/Linux distribution specialized in networking tasks. We will give two LANs access to the internet along with DHCP and DNS cache servers, and then we will connect our networks using OpenVPN in bridging mode. You should be running all these in well under an hour, thanks to the unified configuration interface of Lintrack.

Keyboard shortcuts: Faster than the speed of mouse

Post date: November 26, 2005, 00:11 Category: Miscellaneous Views: 2699 Comments
Tutorial quote: My computer set-up is suboptimal. My desk is too high for me to type on comfortably. My workaround? I type with my keyboard on my lap. That puts the keyboard at just the right height and is kinder to my wrists. My mouse, however, has to sit on my desk. Using my mouse involves moving my hand a foot in each direction.

While this action might conceivably bulk up my arm muscles, I would rather not do my arm exercises while at my computer. Using the mouse is time consuming, distracting, and, most importantly, less ergonomic. While your computer may be better situated than mine, chances are you, too, would work faster if you did not have to use your mouse.

To minimize my mouse use, I learned many of the keyboard bindings for various applications. Many applications use similar bindings, making them even easier to remember.

I have compiled a list of keyboard bindings here for some of the more prevalent applications. Feel free to print them out and keep them next to your computer. It may take you a little time to remember them, but once you do, you will wonder how you ever did without.

Written by Igor Sysoev in 2005, Nginx now hosts between 1% and 4% of all domains worldwide. Although still in beta, Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption.

Serving CGI Scripts With Nginx On CentOS 6.0

Post date: October 23, 2011, 09:10 Category: Miscellaneous Views: 20049 Comments
Tutorial quote: This tutorial shows how you can serve CGI scripts (Perl scripts) with nginx on CentOS 6.0. While nginx itself does not serve CGI, there are several ways to work around this. I will outline two solutions: the first is to proxy requests for CGI scripts to Thttpd, a small web server that has CGI support, while the second solution uses a CGI wrapper to serve CGI scripts.

Optimizing C/C++ programs using the GProf profiler

Post date: May 24, 2005, 18:05 Category: Optimizing Views: 6670 Comments
Tutorial quote: One of the most important things to keep in mind while optimizing an application is: optimize where it counts. It is no use to spend hours optimizing a piece of code that usually runs for only 0.04 seconds anyway.

GProf provides a surprisingly easy way to profile your C/C++ application and spot the interesting pieces right away. A small case study shows how GProf was used to reduce the running time of a real-world application from over 3 minutes to under 5 seconds, by identifying 2 data structures as important and optimizing those.

Historically, the program goes back as far as 1982, when it was introduced on the the SIGPLAN Symposium on Compiler Construction. It is now a standard tool available on virtually all flavors of UNIX.

Reducing MySQL Memory Footprint

Post date: September 19, 2008, 22:09 Category: Software Views: 3197 Comments
Tutorial quote: By default MySQL installs a configuration file with big caches and uses up more memory than is needed on most server setups. If like me you are struggling for free ram you may wish to use MySQL’s my-small.cnf and optimize it a little, here is how to do it.
