  1. How to mount a LUKS encrypted Linux drive in Windows

    Become the world’s top super hacker with this one weird trick

    This is kind of fun, but probably no one will need to do this ever. But the point is you can! So why not? Anyway, suppose you have an encrypted Linux drive and you want to mount it in Windows for whatever reason. Just follow along.

    1. Install Windows Subsystem for Linux 2

      WSL 2 allows you to run a virtualized Linux environment that integrates tightly with the Windows OS. To install it, search for "Turn Windows features on or off" in the Start menu and click the shortcut to open the Settings pane. Scroll down towards the bottom and check the box for "Windows Subsystem for Linux". Then click "OK" to install WSL 2.

    2. Open the Microsoft Store app and install Ubuntu Linux 22.04 LTS

      This is trippy as hell. Ubuntu Linux on an App Store? We have entered the end times indeed.

    3. Confirm it worked by opening Linux in Windows Terminal

      Start the Terminal app, which should be pre-installed. By default it will probably open to a Powershell or Command Prompt. Click the dropdown arrow on the tab bar and you should see "Ubuntu 22.04.2 LTS" or something similar in the dropdown menu. Click it to start Linux!

    4. Run an Administrator Powershell and give WSL 2 access to your physical drive

      These instructions are adapted from Microsoft's own documentation so check that out if you need help. Basically, open a new Powershell as Administrator (right click the shortcut and then "Run as administrator").

      List your physical drives by entering: GET-CimInstance -query "SELECT * from Win32_DiskDrive"

      The command should give you output similar to the following:

      DeviceID           Caption                   Partitions Size          Model
      --------           -------                   ---------- ----          -----
      \\.\PHYSICALDRIVE3 Samsung SSD 980 PRO 2TB   1          2000396321280 Samsung SSD 980 PRO 2TB
      \\.\PHYSICALDRIVE0 WD_BLACK SN850X 4000GB    3          4000784417280 WD_BLACK SN850X 4000GB
      \\.\PHYSICALDRIVE1 Samsung SSD 970 PRO 512GB 1          512105932800  Samsung SSD 970 PRO 512GB
      \\.\PHYSICALDRIVE2 WDBRPG0020BNC-WRSN        1          2000396321280 WDBRPG0020BNC-WRSN

      So, one of the DeviceIDs in the output should map to your LUKS encrypted Linux. Suppose for example it was \\.\PHYSICALDRIVE3, then you can give your WSL 2 environment access to that drive with the following commmand:

      wsl --mount \\.\PHYSICALDRIVE3 --bare

      PROTIP — If you need to do this a lot, you can put that command in a .bat file and run it (as Administrator) anytime you want to mount the drive in WSL 2.

    5. Find your encrypted drive in your WSL 2 shell

      Go back to your Terminal with the Ubuntu Linux shell running, and if everything worked, you should be able to find your encrypted drive with the following command: lsblk -l

      The command should give you output similar to the following:

      sda             8:0    0 363.3M  1 disk
      sdb             8:16   0     8G  0 disk  [SWAP]
      sdc             8:32   0     1T  0 disk  /snap
      sdd             8:48   0     2T  0 disk
      sdd1            8:49   0     2T  0 part

      In this example the sdd1 identifier maps to the encrypted partition on your physical drive.

    6. Decrypt and mount the encrypted drive

      You will need a package called cryptsetup if it's not installed. From your Linux shell, enter sudo apt install cryptsetup if needed.

      Now you can decrypt the volume by entering (for example): sudo cryptsetup luksOpen /dev/sdd1 samsung_980_pro

      ^ The name you put in the last argument of that command is any arbitrary name you want to assign the drive in the device mapper. Just be sure that you use the correct device name for the encrypted partition listed from lsblk (in this example /dev/sdd1).

      Once it's decrypted, you can mount the drive with the following command(s):

      • sudo mkdir /mnt/my_encrypted_drive (if needed)
      • sudo mount /dev/mapper/samsung_980_pro /mnt/my_encrypted_drive

      Obviously you can customize the names and mount location however you see fit.

    7. Now you can access your encrypted drive from Windows Explorer!

      Open a new Explorer window and scroll down the left sidebar until you see "Linux." Click this and you'll be able to browse the filesystem from your Ubuntu 22.04 installation. Simply navigate to /mnt/my_encrypted_drive or wherever you mounted the drive, and you'll have access to your encrypted volume!

    One nice use case for this...

    Having an encrypted drive is just a good idea in general. If your computer is lost or stolen you can keep your private files protected and not worry so much about identity theft or any other bad outcomes from people maliciously accessing your files. Many Windows computers ship without any kind of drive encryption, and Microsoft's own BitLocker disk encryption is only available in "Pro" editions of Windows.

    Speaking of BitLocker, who can even trust that shit? It's a closed source system and Microsoft can swear up and down that it's safe and secure, but for all anyone knows it's backdoor'ed six ways from Sunday. By using Linux LUKS drive encryption in Windows, you at least have open source and provable security. Just make sure your passphrase is strong enough and you're good to go!

  2. My review of Pop!_OS 22.04 vs. MacOS and Windows

    TL;DR: Pop!_OS > Windows > MacOS

    I've been building and tinkering with computers since I was a small child. Originally I would salvage old computer parts that schools and businesses were throwing away, swapping broken parts for whatever working hardware I could find, in the process converting my parents' family room into a junkyard of resurrected IBM PS/2s and dot matrix printers, all of them beeping and clicking and running my childish attempt at an artificial general intelligence.

    Now that I'm grown up, my life is much the same, although instead of finding old junk, I've blown altogether way too much money buying computers and experimenting with new builds. This means I've never been a "PC guy" or a "Mac guy" or a "Linux nerd" or anything else. I'm intimately familiar with Windows, MacOS and many flavors of Linux and I appreciate all of them for what they are.

    But recently, I sold off my Windows and Mac setups and made 2023 my year of Linux on the desktop. And so far I am loving it, thanks in great part to Pop!_OS 22.04, the only Linux distro I've used that fits me like a glove. So in the following post, I will ramble on about Pop!_OS and why I took the plunge.

  3. How to control your Corsair RGB hardware in Linux

    I've been a Corsair fanboy for awhile now. Back in the day Corsair made a name for themselves by selling premium memory kits with lifetime warranties. Then they started releasing computer cases, mice, keyboards, SSDs and water cooling kits, and all of it was really good. Now they're even selling monitors and fully-built gaming PCs. Wow! Take my money, Corsair!

    Anyway Corsair has become notorious for putting RGB LEDs on pretty much everything they sell. (They even offer RGB RAM kits with no RAM!) All of this stuff can be controlled through Corsair's iCUE Application, which is sadly Windows- and MacOS-only. But what about us Linux users? Are we out of luck? The answer may shock you!
