### Part Two
1. Turn on wifi hotspot **or** usb tethering
+### **Verify!**
+You want to verify that you are connected to your Android hotspot.
+Android tether is a router that will stand up a subnet of `192.168.43.0/24` for wifi hotspot,
+and `192.168.42.0/24` for usb tether.
+
+* On linux open a terminal and type `ip addr`
+* on Windows open a `cmd` console and type `ipconfig`
+
+* If tethering via wifi hotspot you should see an ipv4 address of `192.168.43.XX`
+* If tethering via usb you should see an ipv4 address of `192.168.42.XX`

### **ACHTUNG Do Not!**
* **DO NOT** turn on ethernet tethering
* you probably don't have the physical equipment available to do that

The result is quite pleasant: the stability of desktop Debian, but with the rough edges polished smooth, nicely configured fonts and ui, and all the multi-media codecs included. Unfortunately, the LMDE 3 installer does not support disk encryption, but manually setting this up by hand is pretty straightforward. On the other hand, manually setting up your partitions by hand allows extra freedom and flexibility, and so I have chosen a simple luks-encrypted / partition formatted xfs. As far as swap is concerned, my preference is to use a swap file instead of a swap partition. Having a swap file instead of a swap partition is more flexible because obviously you can easily recreate a different size swap file whenever you like (or use none at all), and the encryption requires no extra set up because the / partition is encrypted anyway. Will this work with a dual-boot set up? Of course! Because you have to manually configure the partitions anyway, just arrange them exactly how you would need for dual-boot. Assumes uefi-configured boot, with separate partitions for /boot formatted ext4, /boot/efi formatted fat32, and a regular luks-encrypted partition for / formatted xfs. Prepare The Installation Media Visit the Linux Mint Website and download the iso file for LMDE 3 64bit. Download from torrents if possible, to save bandwidth. verify the sha256 sum of the iso file sha256sum lmde-3-201808-cinnamon-64bit.iso Identify the thumb drive you are going to install from. type lsblk , note the output, and then insert the thumb drive then type lsblk again and note the additional output # lsblk /dev/sdb NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdb 8:32 1 14.5G 0 disk \u251c\u2500sdb1 8:33 1 3.4G 0 part /media/trent/Debian 9.6.0 amd64 \u2514\u2500sdb2 8:34 1 416K 0 part In the above example output we see that our thumb drive is identified as /dev/sdb , and partition /dev/sdb1 is automatically mounted. Take special care that you have accurately identified the thumb drive before proceeding. For the sake of example, we will proceed on the assumption that our thumb drive is identified as /dev/sdb , but you need to compensate accordingly. unmount any partition of the thumb drive that are automatically mounted umount /dev/sdb1 write the disk image to the thumb drive ddrescue -D --force lmde-3-201808-cinnamon-64bit.iso /dev/sdb Boot The Install Disc boot into bios to disable fastboot and secureboot invoke your machine's device boot menu and boot the install disc in uefi mode confirm that you have booted in uefi mode by listing efivars ls /sys/firmware/efi/vars Partition The Hard Drive If you recall we are assuming the target hard drive is /dev/sda , as an example. So, make adjustments as necessary. If you would rather use a different partition tool, make sure the efi partition is an efi partition type, and you definitely need a separate /boot partition. if needed you can clear the drive with wipefs wipefs --all /dev/sda create a new partition table for /dev/sda sgdisk /dev/sda -o create a new efi partition for /dev/sda sgdisk /dev/sda --new=1::+512MiB --typecode=1:ef00 create a new /boot partition for /dev/sda sgdisk /dev/sda --new=2::+1G create a new / partition for /dev/sda sgdisk /dev/sda --new=3 verify your partition work sgdisk /dev/sda -p format the efi partition mkfs.vfat -F32 /dev/sda1 format the /boot partition mkfs.ext4 /dev/sda2 encrypt the / partition, you will be prompted for a password cryptsetup -y -v luksFormat --type luks2 /dev/sda3 decrypt the / partition, you will be prompted for a password cryptsetup open /dev/sda3 cryptroot format the / device mkfs.xfs /dev/mapper/cryptroot Mount The Hard Drive This takes advantage of expert mode in the LMDE installer. create an /target directory mkdir /target mount the / device at /target mount /dev/mapper/cryptroot /target create an /target/boot directory mkdir /target/boot mount the /boot partition at /target/boot mount /dev/sda2 /target/boot create an /target/boot/efi directory mkdir /target/boot/efi mount the efi partition at /target/boot/efi mount /dev/sda1 /target/boot/efi Run The Installer App At this point you're ready to run the live installer. You can click the disc icon on the desktop. The first three pages of the live-installer cover Language,Timezone, and Keymap. The fourth page of the live-installer covers name, password, and hostname. On the fifth page of the live-installer, you come to a partition configuration page. But there is nothing to do, so select expert mode at the bottom of the page.

Unfortunately, the LMDE 3 installer does not support disk encryption, but manually setting this up by hand is pretty straightforward. On the other hand, manually setting up your partitions by hand allows extra freedom and flexibility, and so I have chosen a simple luks-encrypted / partition formatted xfs. As far as swap is concerned, my preference is to use a swap file instead of a swap partition. Having a swap file instead of a swap partition is more flexible because obviously you can easily recreate a different size swap file whenever you like (or use none at all), and the encryption requires no extra set up because the / partition is encrypted anyway. Will this work with a dual-boot set up? Of course! Because you have to manually configure the partitions anyway, just arrange them exactly how you would need for dual-boot.

The result is quite pleasant: the stability of desktop Debian, but with the rough edges polished smooth, nicely configured fonts and ui, and all the multi-media codecs included. Previously, I wrote a guide for installing LMDE3 with disk encryption . The installer for LMDE 4 is different in that it includes support for disk encryption, but not if you need custom partitions such as for a dual-boot configuration . With this in mind, the examples presented below assume that you have Windows 10 installed in 4 partitions, and thus you would want to make 3 partitions (5,6,7) after that, for LMDE4. As with before, with separate partitions for /boot formatted ext4, /boot/efi formatted fat32, and a regular luks-encrypted partition for / formatted xfs. With a separate efi partition for LMDE4, you can then use the computer's device boot menu to select which efi boot entry you want to boot. There is also an advantage in having Windows use the first efi partition, in that if something happens to the Windows efi boot entry, you can fall back to the default efi executable. Whereas, if the efi boot entry for Linux somehow gets wiped, you could repair that easily enough via chroot .

The result is quite pleasant: the stability of desktop Debian, but with the rough edges polished smooth, nicely configured fonts and ui, and all the multi-media codecs included. Unfortunately, the LMDE 3 installer does not support disk encryption, but manually setting this up by hand is pretty straightforward. On the other hand, manually setting up your partitions by hand allows extra freedom and flexibility, and so I have chosen a simple luks-encrypted / partition formatted xfs. As far as swap is concerned, my preference is to use a swap file instead of a swap partition. Having a swap file instead of a swap partition is more flexible because obviously you can easily recreate a different size swap file whenever you like (or use none at all), and the encryption requires no extra set up because the / partition is encrypted anyway. Will this work with a dual-boot set up? Of course! Because you have to manually configure the partitions anyway, just arrange them exactly how you would need for dual-boot.

The result is quite pleasant: the stability of desktop Debian, but with the rough edges polished smooth, nicely configured fonts and ui, and all the multi-media codecs included. Previously, I wrote a guide for installing LMDE3 with disk encryption . The installer for LMDE 4 is different in that it includes support for disk encryption, but not if you need custom partitions such as for a dual-boot configuration . With this in mind, the examples presented below assume that you have Windows 10 installed in 4 partitions, and thus you would want to make 3 partitions (5,6,7) after that, for LMDE4. As with before, with separate partitions for /boot formatted ext4, /boot/efi formatted fat32, and a regular luks-encrypted partition for / formatted xfs. With a separate efi partition for LMDE4, you can then use the computer's device boot menu to select which efi boot entry you want to boot. There is also an advantage in having Windows use the first efi partition, in that if something happens to the Windows efi boot entry, you can fall back to the default efi executable. Whereas, if the efi boot entry for Linux somehow gets wiped, you could repair that easily enough via chroot .

The fourth page of the live-installer covers name, password, and hostname. After this select manual partitioning . On the seventh page of the live-installer, you come to a partition configuration page. But there is nothing to do here. The partition-configuration doesn't even recognize your encrypted partitions. But no matter, because you have already mounted the target file system relative to /target/ , so select expert mode at the bottom of the page. the installer doesn't even recognize the encrypted partitions ... ignore everything on this screen and click the `Expert mode` button Again select forward , and when you come to the page where you configure the location to install grub, that should be the efi partition, i.e. /dev/sda5 . select the efi partition as the location to install grub Then continue with the installation.

But you need to configure crypttab now, because when the installer continues running again, it installs the bootloader and builds the initramfs, and mkinitramfs parses crypttab , and builds and configures the initramfs in such a way that it knows to decrypt your / partition so it can then hand it off to the kernel at boot time (I think). find the UUID of the partition that will be mounted at /dev/mapper/crypttab blkid /dev/sda3 -s UUID And when you find the correct UUID number for /dev/sda3 , use that to configure /etc/crypttab which is actually currently at /target/etc/crypttab . # /etc/crypttab # run the command `blkid /dev/sda7 -s UUID` which outputs # /dev/sda7: UUID=\"da3e0967-711f-4159-85ac-7d5743a75201\", from which derive # cryptroot UUID=da3e0967-711f-4159-85ac-7d5743a75201 none luks Resume Installer App At this point finish running the live installer, and you'll be done. UEFI Fix Well, actually there isn't one. In this scenario having two efi partitions, we rely on the motherboard correctly persisting efi boot entries. So if you are unlucky enough to have one of the HP laptops that forgets efi boot entries, I guess you are out of luck. You might try using a single efi partition instead of two, and maybe that will work. Presumably this would require using VeraCrypt for Windows, instead of Bitlocker (because Bitlocker won't allow Grub to load the Windows bootloader?)

I recalled that hugo requires a third-party theme in order to function. But was a bit of a challenge, because how do you know what is a good Hugo theme? First Version in Bash I ended up writing a little bash script (now deprecated) that scrapes the Github api and generates a little report about Hugo themes. It basically curled json from the Github api, and parsed it with grep, awk, and sed, and eventually spat out a plain text file. Rewrite in Python It was about a year later that I decided to rewrite the script in Python, using sqlite as a database. I discovered how to use the python requests module, got some practice with sqlite, and discovered how to make conditional request against the Github api using ETags and \u2018If-Modified-Since\u2019 (ETags are easier). But this was my first time using python like this. And I have to tell you, it\u2019s a lot moar fun than recursive fibonacci tutorials! Building an HTML5 Table (bootstrap, actually) By the time I had figured out how to collect the data I needed, I realized that I could simply generate an html table right in the python script. rank_hugo_themes.py runs in a cronjob every night, and you can view Hugo Themes Report here.
