If you happen to write to NTFS partitions using non-windows operating systems (such as with ntfs-3g, see this thread for more info), some of your files may have got written containing invalid characters in their names. When such a thing happen, the fix of chkdsk is just to delete them but clearly no one would ever want to have their files deleted to 'fix'!

This little script that I wrote aims to fix the invalid NTFS characters in batch and automatically by renaming the files with invalid characters to valid ones. It only fixes the characters in this set: <>:"\|?* which is pretty enough for most of the problems, but for advanced cases (like reserved names 'com', 'lpt') you must fix manually. Always double check the batch mv commands before running.

Fallacies:

• Does not fix reserved names in Windows (like CON, PRN, AUX, NUL, COM1, COM2, etc).
• Does not fix other illegal combination of characters like 'directory name cannot end with

Installation of NixOS with encrypted root

These are my notes on instaling NixOS 16.03 on a Lenovo ThinkPad X1 Carbon (4th generation) with an encrypted root file system using UEFI.

Most of this is scrambled from the following pages:

• Encrypted Root on NixOS - Nix Wiki
• Installing NixOS - Chris Martin
• Linux administration and use - Earl Douglas
• Installing NixOS on a ThinkPad W540 with encrypted root - Bluish Coder

Setting up NixOs with LUKS encrypted root

Here are my working notes on getting a system up and running.

WARNING: You can run into a hidden problem that will prevent a correct partition setup and /etc/nixos/configuration.nix from working: if you are setting up a UEFI system, then you need to make sure you boot into the NixOS installation from the UEFI partition of the bootable media. You may have to enter your BIOS boot selection menu to verify this. For example, if you setup a NixOS installer image on a flash drive, your BIOS menu may display several boot options from that flash drive: choose the one explicitly labeled with “UEFI”.

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).
