Level Up - Android: How to Flash (Upgrade) Nexus 4 to Android Lollipop 5.0 (Easy)

If you have a Nexus 4, then you can have Android Lollipop now! Google recently released the factory image, and I'm now successfully running it (with root, which will be explained in a later post).

Nexus 4 running Android Lollipop 5.0

This will be a short walk-through because I assume you already have the tools needed, but just need the steps to get the flash done. If you have any questions, then please write a comment and I will update as necessary.

1. Download Android Lollipop 5.0 factory image: https://developers.google.com/android/nexus/images#occam
2. Uncompress the file, possibly twice. I used 7-zip. You should see six files there, including a zip, which you do not have to unzip.
3. Make sure `adb` is in your PATH environment variable, which can be found in %android-sdk%/platform-tools/. Also, you will need `fastboot.exe` from that same folder in your PATH. (I assume you already have the Android SDK and you know what I mean by "Advanced system settings"->Environment Variables->PATH.)
4. Connect your Nexus 4 device to computer, then run `adb reboot-bootloader` in your computer's terminal. This will bring your device to the "fastboot" mode.
5. At the very bottom-left, you should be able to see whether your bootloader is locked or unlocked. It must be unlocked to flash a new system image. If unlocked, you're good, go to the next step. If locked, then run `fastboot oem unlock`. WARNING: Unlocking will erase all data.
6. Open your computer's terminal to where you downloaded and uncompressed the files, and run `flash-all`. That command will run the "flash-all.bat" script which will setup the new system image for you!

Congrats! When the script is done, it will reboot your device and Lollipop will be running. It may take a bit for it to boot the first time.

More info: There sure is a lot more information you could read about this entire process, but that's not what this post is for. These are the minimal instructions (with appropriate warning) for most people wanting to do this. If anybody has some good resources to share, then please add them to the comments.

Now, are you ready to root your Nexus 4?

Level Up - Webmaster: Transfer MediaWiki Instance To Another Domain or Server

I just completed the process for the first time, so it is fresh on my mind. Provided here is an easy summary of the exact links and steps that I needed. I went from MediaWiki version 1.20 to 1.22.2.

MediaWiki recommends only transferring files/database between same versions. So, these steps will also quickly include updating the "old" wiki first before installing a new instance on the new domain.

This information is for small, non-customized wikis. For more important data, you should probably read Manual:Upgrading.

Upgrade to newest stable release (optional)
0. Check requirements by reading the release notes
1. Backup files and database. The different ways include SSH, FTP, and via phpMyAdmin. More info
2. Upgrade files. Latest version. One idea is to upload these new files in a different directory, then change the names of the two directories so that the new one starts serving the files.
2.1. Added back LocalSettings.php, Images folder, and custom extensions.
3. Upgrade database. For the web method, navigate to "/mw-config/index.php". Some requirement checks will be performed during the setup wizard process.
4. Test if successful.

Create MediaWiki instance in the new server/domain
0. Backup files and database if you haven't already done so in the first section.
1. Create new instance of MediaWiki on new domain.
2. Import old settings and files from old domain, and change link locations as appropriate.
3. Test.
