How to fix a USB drive showing up as two drives (fragmented into multiple partitions) on Windows:

1. Hold the Windows key and press X, select PowerShell (Admin), select Yes to the pop-up. You can also use Command Prompt.
2. In the Powershell interface type diskpart to enter the disk partition tool.
3. Type list disk to see all disks listed.
4. Select the USB drive by typing select disk [NUMBER]. Be careful to select the correct drive.
5. Type clean. An error will occur if you have the drive folder open, close the window and repeat the command if this happens.
6. Type create partition primary.
7. Type format fs=ntfs quick to format the drive (you can also choose to set fs=fat32).
8. Type active.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

My explanation of the main concepts in Rust

There are three main concepts with Rust:

1. Ownership (only one variable "owns" the data at one time, and the owner is in charge of deallocating)
2. Borrowing (you can borrow a reference to an owned variable)
3. Lifetimes (all data keeps track of when it will be destroyed)

These are fairly simple concepts, but they are often counter-intuitive to concepts in other languages, so I wanted to give a shot at

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).
