Using QEMU inside a terminal with serial output

I often have a need for a quick virtual machine. Many of them don't require any video output, so having a virtual monitor is a little overkill. Luckily, with a few QEMU switches and brief configuration of the guest VM, you can view console output in a standard terminal on the host system.

My personal bash prompt

Over years of using bash, I've customized my prompt configuration to fit my preferences. I value a minimal appearance, and I prefer to convey information with colors when possible. I also like it if information is hidden until relevant.

Better permissions for uploaded files in Django

Django assigns permissions to any user-submitted files it saves. If you don't explicitly set what these are, it uses an operating system default - which, in most cases, is 0600. If you're unfamiliar with unix-style file permissions, that means the following:

My First "Let's Encrypt" Cert

Now that it is in beta, I decided that I should request HTTPS certificates through the new Let's Encrypt certificate authority. It is free, secure, and provides a unique way of requesting certificates.

Unobtrusive Let's Encrypt requests

My only beef with the Let's Encrypt process is that, by default, the utility wants you to disable your web server in the process of requesting a certificate, so that it can listen on port 80 (or 443) for a verification challenge. I host lots of sites, many of them high-traffic, and that's kind of a deal breaker.

GNUsocial daemons and systemd

After the migration to the new server, my old SysV init script for restarting the queue daemons needed to be updated to systemd.

Setting time, date, NTP, and timezone details on Debian

Setting date and time options on Debian has been placed under the systemd umbrella with the "timedatectl" utility. While I'm not fully convinced that everything belongs in systemd, I do think that having a single location for all time and date related configurations makes sense.

Working with base64 and images

I have been working with base64 encoding a lot recently, specifically regarding image files. Using base64 is a cool way to embed images in your CSS, and happens to be useful when writing Django tests that involve an image file field.

Favorite Openbox Configs

As an Openbox user, I like to tinker. This should not surprise anyone who's used this window manager - it's highly configurable, and very easy to customize.

Color ls output in less

Something that has always bothered me is that my beautiful, colorful ls command output is converted to stark, monochrome text whenever I pipe it to less. Syntax highlighting is extremely helpful when it comes to differentiating directories from normal, extension-less files.

A week of Elementary OS

Last week, I tried to upgrade my Debian desktop to the latest Debian stable. Due to my own ineptitude at setting up my desktop in the first place, and my foolishness in telling aptitude to "ignore recommends" when dist-upgrading, I wrecked my system.

@font-face, Icon Fonts, and Gnome Character Map

Just a quick post to mention an issue I ran into while working with @font-face for a recent design.

Ubuntu Live ISO On A SATA Drive

I found myself in quite the predicament over the Christmas break. I was visiting my family in New York, and wanted to upgrade Mom's old Ubuntu system.

Using The 'at' Command

If you've never used the at command, you're in for a treat. The at command is a utility used to schedule jobs for execution at specific times. The syntax is very simple, and should be easy to pick up for anyone with command-line experience.

Start X Session at Login

In my quest for a cool Openbox desktop that fits me (you know, other than CrunchBang, which has elevated itself beyond sliced bread some time ago :) ), I ended up tearing up a lot of other perfectly nice distros and building some up from a base install. In each, I ended up tearing out GDM. It's little bit hefty for accepting two strings, and it doesn't exactly work with Likewise, which I use at work.

Cool Linux Tool: gcolor2

HP Printer Install on Linux using CUPS

Recently I had to print at work, which required installing a printer on Ubuntu, so I thought I'd share how it went. Long story short: It went awesome.

Ubuntu at Work

As of today, I'll be booting into Ubuntu at work instead of the usual Windows XP. I am psyched.

Tint2, Nitrogen, and Openbox Awesomeness

I've recently transitioned myself over to a Openbox-based desktop by installing Xubuntu and pulling out most of the XFCE stuff. It's been quite the learning experience, and I've discovered a couple things that I thought I should share:

Server Administration for Dummies

I finally got Postfix configured correctly (if not completely) on my VPS. It took a lot of poking, but now I can send and receive mail in SquirrelMail. While this is only the beginning of the configuration, it's a nice feeling to have something "click" and start functioning. I owe it all to the fantastic Postfix documentation - quality stuff they've got there.

Where's Windigo?

At one of our LUG meetings, NYbill noted that I had more or less been a no-show lately on the forums, IRC and everywhere else. I even missed a LUG meeting! So, I wanted to give everybody a little sneak peek on something that I've been working on...

Wine Gaming: Osmos

I picked up a copy of Osmos, an independent game from Hemisphere Games, a couple weeks ago. As is usually the case with independent games, Osmos takes a bit of a diversion from your classic 3D-Shooter or RPG genre restrictions, and invents it's own game type.

Arch Nemesis

I recently had that feeling, the "distro-hopping" inkling that you get when you're too comfortable with familiarity and everything working. After a session in the #linuxoutlaws, I decided that I was going to install Arch Linux on my Dell Mini 9.

Troubleshooting: Right Alt Key in Ubuntu 8.10

After recently taking a trip down memory lane with the old DOS-based Id game, Hexen, under Wine. I discovered a very random issue with my installation of Ubuntu 8.10 (Intrepid Ibex): my right alt key didn't really do anything.

Information Overload

I've recently been reading the planets: Planet Ubuntu and Planet Web Security, in addition to my daily blogs. Planets are really just lots of blogs tied together into one RSS feed, so in essence I just started reading forty more blogs in two additional subscriptions.

The Times We Live In

From the moment I was introduced to the open source movement and free software (as in speech*), I've tried to embrace it. For a web developer, free and open software seems like a perfect pair for the free and open nature of the internet. I've grown accustom to looking under the hood of any web site I come upon, so why should the browser or operating system I use be any different?

Homebrew

My PC is five years old, and starting to show it's age. I built it during my senior year of high school, piece by piece, with extra money I saved up from my pizza delivery job. I bought the more static components first (pieces that wouldn't be outdated as soon as I bought them), like the case and the fans. Slowly, I worked up to the main components, and eventually I had a full computer.

Wine and Dine Your Windows Games

I've been messing around quite a bit with my Linux installation (I'm currently running Kubuntu Linux 7.10) because I'd really like to stay away from my Windows partition as much as possible. A big part of Windows' necessity for me has to do with my crippling addiction to games.

Linux - Our Day Has Come

I heard that Kubuntu, my favorite flavor of Ubuntu, had a new version out. Since I run a dual-boot system with Windows XP and Kubuntu, I did my duty and downloaded the latest version, which just happens to be 7.10 (Gutsy). While I was starting the install process, I noticed a small blue signal strength graph in my taskbar.

Linux - Customize Your Noose

My new year's resolution is to switch to Linux - specifically one of the Ubuntu variants. I'm sick of using Windows and supporting Microsoft in it's efforts to remove the rights of it's users. Linux can (technically) do absolutely anything I need it to do, the trick is getting from here to there.
