+title: Learning Linux like its 1995
+date: 2025-01-13

+
+Using Arch Linux (for Hyprland experiments) takes me back to the mid 1990's when I was learning Linux from the ground up.
+
+At the end of 1994 I was installing Slackware Linux (from 82 floppy disks) and spending hours figuring out what to compile into the Linux kernel (before the days of dynamic loading).  There was a huge amount to learn (usually without my own internet connection).
+
+Arch Linux wiki pages have a huge amount of information, showing all the possible options for every piece of software and service.  This does present a dilemma of choice.
+
+Having experienced many years with Linux, I know many of the concepts and software associated with a Linux system.  I dont need to read all the options, but do find myself scrolling a lot until I find something familiar (or simple).
+
+
+The goals for this month include
+
+- documenting Neovim & Conjure workflow
+- meaningful exercise every day (health permitting)
+- bicycle ride (weather permitting)
+- avoid Hyprland turning into a huge time sync (couch potato time only)
+
+My health took more of a knock this week as I am finding it very difficult to walk.  I've had pain in my right hip for a couple of weeks and on Friday I started walking and felt a sharp pain.  Every step with my right leg is painful and going up and down stairs is particularly painful.
+
+The hip pain coupled with my left knee pain significantly limiting my ability to exercise this week.
+
+Movies this week:
+
+- [Death on the Nile 1978](https://en.wikipedia.org/wiki/Death_on_the_Nile_(1978_film)) with Peter Ustinov as Hercule Poirot, including an all-star cast from the time including David Niven, Angela Landsbury and Betty Davis.

+
+## Neovim
+
+LSP Renaming of namespaces and filenames is the only feature I do not have working with Clojure LSP and Neovim.  nvim-lspconfig supports Clojure but reports the following error when trying to rename a namespace name.
+
+```shell
+Error on prepareRename: Can't rename - client does not support file renames.
+```
+
+The nvim-lsp-file-operations plugin was used but with no success as yet (not sure why).
+
+
+### clojure-lsp command line
+
+`clojure-lsp` is available on the command line path, so a command like this will change the namespace and the namespaces corresponding file name.
+
+!!! NOTE "Clojure LSP rename namespace via command line"
+    ```shell
+    clojure-lsp rename --from gameboard.gameboard.api.scoreboard --to practicalli.gameboard.api.scores
+    ```
+
+## Hyprland
+
+Hyprland has already taken up a lot of time with getting the basics up and running.  It will easily take weeks and most likely months to have a rich configuration with all the eye candy I have seen.  Investing that kind of time is not valuable to me, but I would still like to have an engaing setup.
+
+There is much discussion about configuring Hyprland and lots of different community projects.
+
+
+
+
+```shell
+❯ waybar
+
+(waybar:27164): Gtk-WARNING **: 23:35:32.704: Theme parsing error: gtk.css:6691:68: Invalid name of pseudo-class
+[2025-01-18 23:35:32.740] [info] Using configuration file /home/practicalli/.config/waybar/config.jsonc
+[2025-01-18 23:35:32.741] [error] Error parsing JSON: * Line 71, Column 18
+  Syntax error: value, object or array expected.
+```
+
+The error seems related to the `"icon-size"` key which had the value `${i_task` which seems incomplete structure.
+
+Chaninging `"icon-size"` to a specific icon size seems to make waybar run (at least via the command line)
+
+```config title="/home/practicalli/.config/waybar/config.jsonc"
+"wlr/taskbar": {
+    "all-outputs": true,
+    "active-first": true,
+    "markup": true,
+    "format": "{icon}",
+    "rotate": "0",
+    // "icon-size": ${i_task  #(1)
+    "icon-size": "8"
+    },
+```
+
+1. icon-size line seems incomplete, commented and replaced with a fixed value
+
+
+The `waybar` command in a terminal runs waybar okay, although there are some warnings to review.
+
+```shell

+![Hyprland configured with HyDE after fixing waybar configuration](https://github.com/practicalli/graphic-design/blob/live/os/hyprland/hyprland-hyde-with-waybar.png?raw=true){loading=lazy}
+
+
+## ArchLinux
+
+Set the local time via the command line iusing the `timectrl` command
+
+ArchLinux uses an NTP server that automatically sets the local time from a remote server (at least after installing HyDE).
+
+To manually set the time with `timedatectl` the NTP server must be disabled first.
+
+!!! NOTE "Disable NTP server"
+    ```shell
+    timedatectl set-ntp false
+    ```
+
+!!! NOTE "Set the local time"
+    ```shell
+    timedatectl set-time "2025-01-18 22:00:00"
+    ```
+
+!!! NOTE "enable NTP server"
+    ```shell
+    timedatectl set-ntp true
+    ```
+
+!!! NOTE "Check current date"
+    ```shell
+    date
+    Sat Jan 18 10:00:09 PM UTC 2025
+    ```
+
+??? EXAMPLE "timedatectl --help"
+    ```shell
+    timedatectl [OPTIONS...] COMMAND ...
+
+    Query or change system time and date settings.
+
+    Commands:
+      status                   Show current time settings
+      show                     Show properties of systemd-timedated
+      set-time TIME            Set system time
+      set-timezone ZONE        Set system time zone
+      list-timezones           Show known time zones
+      set-local-rtc BOOL       Control whether RTC is in local time
+      set-ntp BOOL             Enable or disable network time synchronization
+
+    systemd-timesyncd Commands:
+      timesync-status          Show status of systemd-timesyncd
+      show-timesync            Show properties of systemd-timesyncd
+      ntp-servers INTERFACE SERVER…
+                               Set the interface specific NTP servers
+      revert INTERFACE         Revert the interface specific NTP servers
+
+    Options:
+      -h --help                Show this help message
+         --version             Show package version
+         --no-pager            Do not pipe output into a pager

+      -H --host=[USER@]HOST    Operate on remote host
+      -M --machine=CONTAINER   Operate on local container
+         --adjust-system-clock Adjust system clock when changing local RTC mode
+         --monitor             Monitor status of systemd-timesyncd
+      -p --property=NAME       Show only properties by this name
+      -a --all                 Show all properties, including empty ones
+         --value               When showing properties, only print the value
+      -P NAME                  Equivalent to --value --property=NAME
