getting a wordpress linux box up in 5 minutes (*)

diving

If you’ve ever went to the trouble of setting up WordPress on a Windows machine yourself, going through a PHP, MySQL and phpMyAdmin installation, then sort through all the IIS crap you run into you’ll love TurnKey Linux virtual appliances (aka pre-installed virtual machine boxes).

You can for example download a WordPress appliance which has all the stuff mentioned above pre-installed, launch it in VMWare Player, go through a 5 minute config et voilà! You have your very own virtual Ubuntu box up and running with a fully functioning fresh WordPress install on it. You can even flex your 1337 Linux command line skillz through “Shell in a box” which simulates a shell window in your browser. Or you can use SFTP/SSH. Wickedness indeed.

There’s more fun to be had though. Lot’s of other cool appliance are available containing tons of Open Source Software to be messed with. There’s a LAMP stack, one for Drupal, Ruby (how hip!) etc. Not quite geeky enough for ya? Well alright, go ahead then, get one of those appliances and upload it to Amazon EC2 and be all “in the cloud”. Cause they can do that you know. Oh yeah.

Don’t know if it’s a good idea though. Security wise and all.

(*) If you have VMWare Player installed and already downloaded the zip file of course. :)

still a windows geek

Originally this post was called “I’m a Windows geek”, and was about how I installed Ubuntu after not being able to reinstall Windows XP because something was making the hardware detection lock up. Using Ubuntu I did manage to get through the hardware detection, and eventually diagnosed the problem to be able to reinstall the Redmond OS.

I spent a few days in Ubuntu back then, as it was the only running OS on my machine, and I thought that was a good time to find out if I could do everything I did on my Windows machine. At first I was impressed. Ubuntu installed without a glitch, basic software was installed and the UI was slick. Problem was I had to find replacement Linux tools for all the stuff I was used to in Windows and then I started noticing I’ve gotten quite used to the WinWorld apparently.

Little things ended up being very frustrating though. Shortcuts that work different in FireFox, mouse wheels that didn’t work at all… A lot didn’t feel intuitive coming from an MS system.

Eventually I managed to reinstall XP, and I totally gave up on the Ubuntu setup. A number of months ago I retried the Ubuntu path, upgraded it to the latest version and give it another shot. I Just noticed that it has been a few months again since I even booted it…

No matter how much Linux pwnz the Windows OS according to some, when you’re used to it, you kind of expect the same features. It sucks having to give up your favourite programs for alternatives that aren’t quite the same. Some of them are in essence equally good, but it doesn’t have to be that different to start sucking compared to what you’re used to.

WinAmp for instance totally rocks. I haven’t seen anything quite as good on Linux (or on Windows for that matter). Maybe I’m wrong though. I haven’t spent quite as much time searching for software tools on Linux than I have on Windows, I have to admit that. But luckily things are getting better at that front. Since I used a lot of FOSS software, and a lot of that is being ported over both platforms, I don’t have to stop using my beloved FireFox, GIMP, Open Office or VLC, which is great. So migrating is becoming a lot easier because of this, but not quite easy just yet.

One other huge frustration is that in Linux some things simply don’t work. ATI video cards anyone? Dual head displays? In fact, one of the differences between Windows and Linux in my eyes is this:

On Windows I’m surprised if a new piece of hardware I got doesn’t work.
On Linux I’m surprised (and happy) if it does.

I’ve gotten used to my OS to just work for me. I don’t feel like spending most of my time figuring out how to get something basic to work. It can be fun digging into configuration files and advanced settings if you have the time to do so, but in most cases I just want to run Setup.exe > Next > Next > Done and start using the damn app. By using Ubuntu I rediscovered how easy it can be to setup a Windows system.

So I guess I’m still a Windows geek for now.
Vista here I come? Oh crap…

how to fix GRUB problems

After replacing a dead power supply I found out my GRUB boot menu refused to start the selected OS.
It just spat out this horrifying message:

Grub Error 21: Selected disk does not exist

After some Google-ing and asking some questions in the #grub IRC channel I downloaded a tool called SuperGrubDisk, wrote it to an oldskool floppy disk and managed to boot Windows and Ubuntu once again.

Now I at least knew my system wasn’t completely screwed, and it was just GRUB acting up for some reason. Well the reason was actually that during the initial installation my hard drive was recognized as hd1 instead of hd0. For some reason this had now changed after unplugging and replugging cables to replace the power supply. Thanks to SuperGrubDisk I managed to figure out this was the problem.

Using info on their wiki I figured out the GRUB configuration file is located in /boot/grub/menu.lst, and can be edited with any text editor. After manually changing the HD settings, all is well again.
So hurray for open source, and configuration files in plain text format!

While I was in there, I also changed the default startup OS and shortened the default 10 seconds to five. I must have thought about doing that for ages, but never got around to it.

finding out where software is installed on ubuntu

The Infamy of a Story Never Told by Felipe Morin

For someone not accustomed to the Unix file system hierarchy you might have a hard time figuring out where the heck that package manager installed software you just selected. That is when it doesn’t occur automatically in your Ubuntu Application menu in the first place. Well there is a simply way to figure that out without having to look through all those mysterious usr, var and etc folders.

  1. Open up your Synaptic Package manager.
  2. Search and select the package you want to know the installation folder of.
  3. Right click it, and select Properties.
  4. Go to the Installed files tab of the property window.
  5. There you have it, all installed files and there location on your disk.

Now you can manually browse to it and run it by double clicking the binary.
If you want to add a shortcut or launcher to your Applications menu for the newly installed app, you can do this by right clicking the Applications menu, and selecting “Edit menus”.
