-This is a bit of a different post than I usually write, but quite interesting
-one to me. River Sava has plenty of hydropower plants located down the stream.
-This makes regulating the strength of a current easier than normally. Because of
-lower stream strength and high temperatures, algae has formed on the river.
-This is the first time I've seen something like this in my whole life.
-Below are some photographs taken from a DJI drone capturing the event.

-An amazing game deserves an amazing guide. All this material can be find in some
-form on another on [craw's](https://github.com/crawl/crawl) official repository.
- [DCSS Quickstart](/assets/notes/dcss-quickstart.pdf) - Very short introduction to the
-  game
- [DCSS Manual](/assets/notes/dcss_manual.pdf) - Extensive manual about the game
-![Dungeon Crawl Stone Soup](/assets/notes/dcss.jpg){:loading="lazy"}
-**Movement and Exploration**
- You can move around with the numpad (try numlock on and off), vi-keys, or
-  clicking with the mouse. Arrow keys work, though you can't move diagonally
-  with them. Pressing Shift and a direction will move until you see/hit
-  something.
- Pressing `>` will take you down a staircase, and `<` to go up a staircase.
- You can open doors by walking into them, and close them with `C`.
- You can autoexplore by pressing `o`.
- You can re-view recent messages with `Ctrl-p`.
-**Monsters and Combat**
- You can pick up items with `,` or `g`.
- Wield weapons with `w`. Weapons have different stats.
-  - (You may also engage in Unarmed Combat, though it isn't very effective when
-    untrained).
- Attack monsters in melee by walking in their direction (or with
-  Ctrl-direction).
- You can wait with `.` or `s`, passing your turn - such as to get monsters into
-  a corridor with you.
- You can rest with `5`, waiting until you are fully healed, or something
-  noteworthy happens.
- Either mouseover and rightclick, or use `x` then `v` on the monster to examine
-  monsters. Monsters with a red border are 'dangerous' relative to your current
-  XP level (XL).
- Quiver (often ranged) actions for further use with `Q`.
- You can fire ranged weapons manually with `f`, or auto-target your quiver with
-  `p` or `Shift-Tab`. Throwing weapons can be thrown immediately, while
-  launchers (like bows) need to be wielded first.
-**Items and Inventory**
- View your inventory by pressing `i`. Most item related commands can also be
-  done with this menu.
- You can wear amour with `W;` amour gives `AC`, while heavier body armour
-  reduces `EV`.
- Autoexplore will automatically pick up useful items, such as potions and
-  scrolls, if you aren't in danger.
- You can read scrolls with `r` and drink ("quaff") potions with `q`.
- Equipment items may have brands, with special properties. Branded equipment is
-  blue when unidentified.
- Equipment items may be artifacts, often with unique properties, and are
-  unmodifiable. They are written in white.
- You can evoke wands with `V`.
- You can put on jewelry with `P`, and remove it with `R`.
- Gold is used in shops, which can be interacted with by either `>` or `<`.
-**Magic and Spellcasting**
- Once you find a spellbook, you can memorize spells with `M`.
- You need to be the same XL as the spell's spell level in order to learn it, in
-  addition to training magical skill (to lower failure rate).
- Cast spells by pressing `z`, then the letter assigned to the spell. You may
-  also Quiver a spell and then use it like a ranged weapon (with Shift-Tab).
- You can view your memorized spells by pressing `I` (capital-i) or `z`.
- Like HP, you can recover MP by resting (with 5).
- Many spells can be positioned more effectively, or combined with other spells,
-  in order to get (more effective) use out of them.
- Heavier body amour and shields hamper spellcasting.
-**Gods and Divine Abilities**
- You may look at a god's overview by praying at their altar (with `>` or `<`).
-  After praying, you can worship the god by pressing Enter afterwards.
- Gods all have unique features about them. Trog, the god of the tutorial, is
-  also the god of rage and bloodshed, and so despises spellcasting.
- Gods like and dislike different things. Most gods either like killing things
-  (like Trog) or exploring new areas (like Elyvilon), rewarding you piety
-  (divine favor) for doing so.
- You should learn to use and even rely on divine abilities often, as they are
-  usually very strong. Trog's Berserk gives you 1.5x health, 1.5x speed (to all
-  valid actions), and a big damage boost. Note that Berserk prevents most
-  actions other than move and melee attack, and runs out very quickly if you
-  aren't attacking. And after berserk ends, you are slowed down and can't
-  berserk again for a short time.
- In addition, the vast majority of abilities consume piety in the process.
-  Regardless, this ability is very cheap, and the benefits are incredible, so
-  don't hold back!
- Pressing `^` will let you view your current god, abilities, and piety.

-I often use `grep` to search for todo's in my code and other people's code and
-then pipe them in `less` and I missed having colors that grep outputs in `less`.
- Grep's `--color=always` use markers to highlight the matching strings.
- Less's `-R` option outputs "raw" control characters.
-You could use `alias grep='grep --color=always'` and `alias less='less -R'` or
-create todo function in your `.bashrc` that accepts first argument as search

-A simple way to make presentations without using desktop apps or using online
-services is https://github.com/remarkjs/remark.
-First create `index.html` and be sure you make changes to `config` variable.
-```html
-<!DOCTYPE html>
-<html>
-<head>
-    <title></title>
-    <meta charset="utf-8">
-    <style>

-        }
-        .remark-code,
-        .remark-inline-code {
-            font-family: 'SF Mono';
-            font-size: medium;
-            background-color: gainsboro;
-            border-radius: 5px;
-            padding: 0 5px;
-        }
-    </style>
-</head>
-<body>
-    <textarea id="source"></textarea>
-    <script src="https://remarkjs.com/downloads/remark-latest.min.js"></script>
-    <script>
-                const config = {
-                        title: 'My presentation',
-                        file: 'presentation.md',

-        remark.create({ sourceUrl: config.file });
-    </script>
-</body>
-</html>
-```
-Now the markdown file `presentation.md` with presenetation. `---` is used to
-separate slides. Other stuff is just pure markdown.
-```md
-class: center, middle
-# Main title of the presentation
---
-# Fist slide

-Alacritty by default makes all links in the terminal output clickable and this
-gets annoying rather quickly. I liked the default behavior of Gnome terminal
-where you needed to hold Control key and then you could click and open links.
-To achieve this in Alacritty you need to provide a `hint` in the configuration
-file. Config file is located at `~/.config/alacritty/alacritty.yml`.
-```yaml
-hints:
-  enabled:
-  - regex: "(mailto:|gemini:|gopher:|https:|http:|news:|file:|git:|ssh:|ftp:)\
-            [^\u0000-\u001F\u007F-\u009F<>\"\\s{-}\\^⟨⟩`]+"
-    command: xdg-open
-    post_processing: true
-    mouse:
-      enabled: true
-      mods: Control
-```
-The following should work under any Linux system. For macOS, you will need to
-change `command: xdg-open` to something else.
-Now the links will be visible and clickable only when Control key is being
-pressed.

-Nix is amazing for making reproducible cross OS development environment.
-First you need to [install Nix package
-manager](https://nixos.org/download.html).
- Create a file `shell.nix` in your project folder.
- In the section that has `python3` etc add programs you want to use. These can
-  be CLI or GUI applications. It doesn't matter to Nix.
-```nix
-{ pkgs ? import <nixpkgs> {} }:
-  pkgs.mkShell {
-    nativeBuildInputs = with pkgs.buildPackages; [
-          python3
-          tinycc
-        ];
-}
-```
-And then run it `nix-shell`. By default it will look for `shell.nix` file. If
-you want to specify a different file use `nix-shell file.nix`. That is about it.
-When the shell is spawned it could happen that your `PS1` prompt will be
-overwritten and your prompt will look differently. In that case you need to
-either do `NIX_SHELL_PRESERVE_PROMPT=1 nix shell` or add
-`NIX_SHELL_PRESERVE_PROMPT` variable to your `bashrc` or `zshrc` file and set it
-to `1`.
-I also have a modified `PS1` prompt for Bash that I use and it also catches the
-usage of Nix shell.
-```sh
-NIX_SHELL_PRESERVE_PROMPT=1
-parse_git_branch() {
-        git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
-}
-is_inside_nix_shell() {
-        nix_shell_name="$(basename "$IN_NIX_SHELL" 2>/dev/null)"
-        if [[ -n "$nix_shell_name" ]]; then
-                echo " \e[0;36m(nix-shell)\e[0m"
-        fi
-}
-export PS1="[\033[38;5;9m\]\u@\h\[$(tput sgr0)\]]$(is_inside_nix_shell)\[\033[33m\]\$(parse_git_branch)\[\033[00m\] \w\[$(tput sgr0)\] \n$ "
-```
-And this is what it looks like when you are in a Nix shell. Otherwise that part
-of prompt is omitted

-Message from 10/GUI team (page 10gui.com does not exist anymore):
-*Over a quarter-century ago, Xerox introduced the modern graphical user
-interface paradigm we today take for granted.*
-*That it has endured is a testament to the genius of its design. But the
-industry is now at a crossroads: New technologies promise higher-bandwidth
-interaction, but have yet to find a truly viable implementation.*
-*10/GUI aims to bridge this gap by rethinking the desktop to leverage technology
-in an intuitive and powerful way.*

-I had a 4 webm videos (each 492x451) that I wanted to combine to be played side

-[Kdenlive](https://kdenlive.org/) and failed to do it in an easy way. I needed
-this for Github readme file so it also needed to be a GIF.
-The following is the [ffmpeg](https://ffmpeg.org/) version of it.
-```sh
-ffmpeg -y \
-  -i 01.webm \
-  -i 02.webm \
-  -i 03.webm \

-        [2:v] trim=duration=8, setpts=PTS-STARTPTS, scale=492x451, fps=6 [a2]; \
-        [3:v] trim=duration=8, setpts=PTS-STARTPTS, scale=492x451, fps=6 [a3]; \

-  -map "[v]" \
-  -crf 23 \
-  -preset veryfast \
-  trigraphs.gif
-```
- This will produce `trigraphs.gif` that is also scaled to max 1000px in width
-  (refer to `scale=1000:-1`).
- The important part for 4x1 stack is `xstack=inputs=4:layout=0_0|w0_0|w0+w1_0|w0+w1+w2_0`.
- This will also cap frame rate to 6 (refer to `fps=6`) since that is enough and
-  this makes playback of GIFs smoother in a browser.

-Normally you define images with `![]()` in markdown files. But jekyll also
-provides a way to adding custom attributes to tags with `{:attr="value"}`.
-If you have lots of posts this command will append `{:loading="lazy"}` to all
-images in all your markdown files.
-```md
-![image-title](/path/to/your/image.jpg)
-```
-will become
-```md
-![image-title](/path/to/your/image.jpg){:loading="lazy"}
-```
-Shell line bellow. Go into the folder where your posts are (probably `_posts`).
-```sh
-find . -type f -name "*.md" -exec sed -i -E 's/(\!\[.*\]\((.*?)\))$/\1{:loading="lazy"}/' {} \;
-```
-Under the hood this adds `loading="lazy"` to HTML `img` nodes.
-That is about it.

-Easy way to extract line ranges (from line 200 to line 210) with sed.
-```sh
-sed -n '200,210p' data/Homo_sapiens.GRCh38.dna.chromosome.18.fa
-# then pipe it to a new file with
-sed -n '200,210p' data/Homo_sapiens.GRCh38.dna.chromosome.18.fa > new.fa
-```
-`head` or `tail` could be used to extract from begining of the end of the file.

-I mostly play Dungeon Crawl Stone Soup online on Ohio, USA: cbro.berotato.org server and
-when you start playing you can select the version you want to play. Each instance also
-has `rc` file that can customize the way the game behave.
-This is my sane defaults config. It zooms in the game without needing to zoom in the
-browser and it also adds a bit of delays in exploring and it stops at fight.
-```ini
-autofight_stop = 80
-explore_auto_rest = true
-explore_delay = 20
-tile_cell_pixels = 48
-tile_font_crt_size = 24
-tile_font_stat_size = 24
-tile_font_msg_size = 24
-tile_font_tip_size = 24
-tile_font_lbl_size = 24
-tile_map_pixels = 0
-tile_filter_scaling = false
-```
-All the possible options are documented in the [Dungeon Crawl Stone Soup Options
-Guide](https://github.com/crawl/crawl/blob/master/crawl-ref/docs/options_guide.txt)

-I have had some issues with Ollama not being up-to-date. If Ollama is installed with a curl command, it adds a systemd service.
-```sh
-sudo systemctl stop ollama
-sudo systemctl disable ollama
-sudo rm /etc/systemd/system/ollama.service
-sudo systemctl daemon-reload
-sudo rm /usr/local/bin/ollama
-sudo userdel ollama
