Control Ingress (incoming) bandwidth... with Bittorrent and others

I wanted to download a file, but we just got this awesome high speed fiber optic internet...

RAID 5 Reliability is Worse than RAID 1 Reliability, and it gets worse...

It was just kind of intuitive to me that adding more disks to a RAID 5 array would increase the opportunities for failure, but it never occurred to me that going from 3 disks to 4 disks nearly doubled your chance of failure, but it does. It also didn't occur to me that RAID 1 is significantly more reliable than RAID 5.

Ubuntu Server Installation Notes for Partitioning a 2 Disk System to Boot From a RAID 1 Device

This note explains how to install Ubuntu Linux Server on a computer with two hard disks, with RAID 1, so it boots from the array. The entire installation, including partitioning and RAID administration, is done through the installer, and doesn't really require any access to the commands. (This is a work in progress, and we don't have screenshots yet.)

The Value of Practice

Nothing beats practice. No amount of reading documentation and theory will teach as much as that same material combined with a system to play on. A good tutorial is even better.

Great Format for Instructions (Setting up UCSPI-TLS on Qmail)

This instructional page I just worked through about setting up UCSPI-TLS with Qmail was really good. It has all the steps, and they're numbered and indented. I just think it's a great format for "howto"s, because if you're discussing it with someone else, you can refer to a specific step.

Got Semi-Scammed by Discount SSL Vendor Comodo with "PositiveSSL CA 2"

(Just to be fair, I think the SSL cert business is a scam, so there.)

Installing XCP-XAPI on Ubuntu Server 12.04 LTS

(I'm still setting up my system.)

Supermicro Server Keeps Booting after 5 Minutes

I got this snazzy used Supermicro server, and after I set it up to run SSH, and I started to configure it, it started to reboot every five minutes.

Parity in Computer Data, What is It?

Parity, in computer data, is a bit that's set or unset so the total number of bits is either even or odd. It's an extra bit, and it's added as a check on the data.

EasyCZ Button Switchboard

This is a simple (or simplistic) Linux GTK+ application that shows a button panel or "switchboard". Each button executes a script.

Windows: Migrate Files to a New Server, Windows 2008 R2 and Windows 2003

This is probably not the "best practice" but it's what I'm doing lately to migrate files between servers, desktops, etc. MS has a tool that uses DFS to migrate data and maintain UNC paths, but, whenever I see systems that map paths to physical data on Windows, I worry.

ZyXEL ZyWALL USG-50 - Backing Up the Configuration

The usg-50 has a pretty flexible system for saving configurations. From the Maintenance:File Manager:Configuration File screen, you manage your configuration files.

HP V1910 - Backing Up the Configuration

The V1910 switch requires that all configurations be saved, or they'll be lost after a power cycle. I'm sure all users learn this pretty quickly after spending time configuring a switch, and assuming that it was saved into the switch's nvram. They unplug the switch, move it, and then discover all their work is lost.

Netgear GS108T - Saving the Configuration

The 108T doesn't seem to have a regular upload and download screen. Instead, it can save the configuration to a TFTP server. Talk about weird.

Vanishing Window Managers? LOL

I think Windows sucks, but one thing is for sure - the windows are there.
