If you think that one bit is enough to store this information, you'd be wrong.\n\nIn order to keep the binary layout of a program simple and convenient, most languages store information in 8 bit (1 byte) blocks.\nIf you allocate a `bool` in Rust or (most) other languages that are based on LLVM, [it will take up 1 `i1`, or 1 byte of memory](https://llvm.org/docs/LangRef.html#simple-constants).

{"pageProps":{"post":{"slug":"2021-01-13-512kb-club","markdownBody":"\nJavaScript rules the web, literally. In fact, this website is built with JavaScript (Next.js). I recently started to think about if I really needed this much overhead for a simple site like this. After all, I don't have any fancy user interaction features or complex animation that would justify the JavaScript on this page.\n\nThere is a new (no, not that new) philosophy called [the lean web](https://leanweb.dev/). It essentially tries to keep websites tiny and semantically correct. This has many benefits, ranging from less pollution generated by your site to improved SEO, since many search engines favor a semantically correct website over a site that abuses JavaScript to mimic the features, that are baked into html anyway.\n\nIn order to get lean, I decided to join [the 512KB club](https://512kb.club/). This website lists sites that are below 512KB in total (uncompressed, with all dependencies). To get below that mark, I had to remove my face from the frontpage (I'm sure you'll miss it😅), since the image itself was roughly 750KB. I'm now just below 500KB, which qualifies me to join the blue team.\n\n[](https://512kb.club)\n\nI'm not planning to stop here though. I think keeping a website small and simple is an excellent practice. My next step will be to get rid of all the JS junk on this site and only rely on HTML and CSS. I still want to be able to write my posts in Markdown, so I will have to come up with a way to generate pages from them. A safe bet for this would be to use a SSG like [Hugo](https://gohugo.io/). Frankly, [writing my own simple SSG probably wouldn't hurt either](https://erikwinter.nl/articles/2020/why-i-built-my-own-shitty-static-site-generator/). Let's see how high I can climb the ranks of the 512KB club.

{"pageProps":{"post":{"slug":"2021-01-13-512kb-club","markdownBody":"\nJavaScript rules the web, literally. In fact, this website is built with JavaScript (Next.js). I recently started to think about if I really needed this much overhead for a simple site like this. After all, I don't have any fancy user interaction features or complex animation that would justify the JavaScript on this page.\n\nThere is a new (no, not that new) philosophy called [the lean web](https://leanweb.dev/). It essentially tries to keep websites tiny and semantically correct. This has many benefits, ranging from less pollution generated by your site to improved SEO, since many search engines favor a semantically correct website over a site that abuses JavaScript to mimic the features, that are baked into html anyway.\n\nIn order to get lean, I decided to join [the 512KB club](https://512kb.club/). This website lists sites that are below 512KB in total (uncompressed, with all dependencies). To get below that mark, I had to remove my face from the frontpage (I'm sure you'll miss it😅), since the image itself was roughly 750KB. I'm now just below 500KB, which qualifies me to join the blue team.\n\n[](https://512kb.club)\n\nI'm not planning to stop here though. I think keeping a website small and simple is an excellent practice. My next step will be to get rid of all the JS junk on this site and only rely on HTML and CSS. I still want to be able to write my posts in Markdown, so I will have to come up with a way to generate pages from them. A safe bet for this would be to use a SSG like [Hugo](https://gohugo.io/). Frankly, [writing my own simple SSG probably wouldn't hurt either](https://erikwinter.nl/articles/2020/why-i-built-my-own-shitty-static-site-generator/).

{"pageProps":{"post":{"slug":"2021-01-15-compiling-your-own-kernel","markdownBody":"\nI'm currently in the midst of fiddling around with the kernel a bit, and I figured I just documented my process a bit. Unfortunately, since I'm using a Mac for day to day work, I have to rely on a virtual machine to run anything Linux-related. VirtualBox doesn't support the most recent kernels (5.9 is the most recent supported one), so there won't be any cutting-edge development happening here. I decided to use ubuntu as my guest system, since it's very easy to set up.\n\nSo, the first step is to get the sources. You could simply go ahead and download a specific release from [kernel.org](https://kernel.org/), but since I want to hack on it, I decided to go the git-route. Simply download the sources from [their repo](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/) and check out the tag you want to build.\n\n> **Note**: this might take a while. Their repository is huge! If you want to only need the `HEAD` and want to build on bare-metal (no VirtualBox), you could only clone the latest commit using `git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git --depth=1`.\n\nNext up, you need to generate a `.config`. This file describes which features you want to compile into your kernel. To make a generic config that only compiles drivers for the hardware of your system, you can run the following commands:\n\n```bash\n# Copy the config of your current kernel into the repo\nmake oldconfig\n\n# Only enable modules that are currently used by the system\nmake localmodconfig\n```\n\nNow, let's get to actually compiling the kernel. In my case, I assigned 4 cores to my VM. The `-j` option tells make to run 4 jobs in parallel.\n\n> **Caution**: Just providing -j will freeze your system, since make will try to launch an infinite amount of processes!\n\n```\nmake -j4\n```\n\nAgain, this might take some time. Go for a walk, get a coffee or watch your favorite TV-show. After compilation has finished, we need to install the kernel. To do so, run the following commands:\n\n```\nsudo make modules_install\nsudo make install\n```\n\nIn order to boot, we need to tell our bootloader about our new kernel. Run this command to update your grub config:\n\n```\nsudo update-grub2\n```\n\nAnd voila! Your new kernel should be ready.\n\nReboot the system, and grub should pick up the new kernel and boot to it. If that's not the case, you should be able to pick the kernel from the grub menu under `advanced options`.\n\n## Retrospective\n\nI found that building my own kernel is a highly educational and fun experience. Using VirtualBox is a pain in the `/dev/null` to work with, since it has to add a lot of overhead to the system in order to work. You sometimes have to wait over 6 month until the support for a new kernel arrives. This problem should not apply if you compile on bare metal systems.\n\nThanks for your time!\n\nThis is post 004 of [#100DaysToOffload](https://100daystooffload.com/).\n","frontmatter":{"title":"Compiling your own kernel","date":"2021-01-15","tags":"linux, guide, 100DaysToOffload, infrastructure, tech"},"tags":["linux","guide","100DaysToOffload","infrastructure","tech"]},"recommendedPosts":[{"slug":"2024-04-11-a-simple-search-bar","frontmatter":{"title":"A simple search bar","date":"2024-04-11","tags":"guide, note, meta, web, tech, programming"},"tags":["guide","note","meta","web","tech","programming"]},{"slug":"2024-04-04-pandoc-convert-links-to-footnotes-the-easy-way","frontmatter":{"title":"Pandoc: Convert links to footnotes (the easy way)","date":"2024-04-04","tags":"guide, note, writing, til, tech, programming, pandoc"},"tags":["guide","note","writing","til","tech","programming","pandoc"]},{"slug":"2024-04-02-fuck-trees-use-tags","frontmatter":{"title":"Fuck trees, use tags","date":"2024-04-02","tags":"note, opinion, tech"},"tags":["note","opinion","tech"]},{"slug":"2024-01-18-cost-per-request","frontmatter":{"title":"Cost per Request","date":"2024-01-18","tags":"infrastructure, aws, note, opinion, devops, tech"},"tags":["infrastructure","aws","note","opinion","devops","tech"]},{"slug":"2024-01-06-a-better-publishing-workflow-for-static-blogs","frontmatter":{"title":"A better publishing workflow for static blogs","date":"2024-01-06","tags":"guide, note, meta, writing, web, github, tech"},"tags":["guide","note","meta","writing","web","github","tech"]}]},"__N_SSG":true} |

{"pageProps":{"post":{"slug":"2021-01-26-vim-macros","markdownBody":"\nFor a long time, macros in Vim were a huge mystery for me. I knew they existed, but I didn't know how or why you'd use them. A recent task of mine involved replacing the unsafe operator (`!!`) in a large kotlin codebase with a null-safe operator (`?`). This game me a good opportunity to learn about macros. This is a snippet I encountered numerous times:\n\n```kt\nmLeftButton!!.text = \"Left\"\nmLeftButton!!.setOnClickListener(leftListener)\nmLeftButton!!.visibility = View.VISIBLE\nmRightButton!!.text = \"Right\"\nmRightButton!!.setOnClickListener(rightListener)\nmRightButton!!.visibility = View.VISIBLE\n```\n\nYou could go ahead and change each line individually, or use the IDEs built in \"multi-cursor\" tool to save you some work. But, let me show you how I automated this using a Vim-Plugin for Android Studio. Not that the plugin matter, it will work in every Vim-like editor.\n\nA macro in Vim works like this:\n\n1. Record any sequence of keystrokes and assign them to a key\n1. Execute that sequence as often as you wish\n\nSo let's see how we'd do that.\n\n## Recording a macro\n\nTo record a macro in Vim, you press `q` (In normal mode) followed by a key you want to assign the macro to. So, if you wanted to record a macro and save it to the `q` key, you'd press `qq`. Vim will notify you that a macro is being recorded. Now, you can press the keystrokes that define your actions. When you're done, press `q` in normal mode again to quit your macro.\n\nComing back to my task, I would want to do the following:\n\n1. `qq` Record a macro and save it to the `q` key\n1. `_` - Jump to the beginning of the line\n1. `f!` - Find next occurrence of `!`\n1. `cw` - Change word (Delete word and enter insert mode)\n1. `?.` - Insert the new characters\n1. `<esc>` - Enter normal mode\n1. `j` - go down a line\n1. `q` - Finish macro\n\nIf everything went right, this line:\n\n```\nmLeftButton!!.text = \"Left\"\n```\n\nShould now look like this:\n\n```\nmLeftButton?.text = \"Left\"\n```\n\nand your macro should be saved under the `q` key.\n\n## Using the macro\n\nIn order to use a macro in vim, you press the `@` key, followed by the key the macro is saved under. Since our macro is defined as `q`, we'd press `@q`, and the macro is executed immediately.\n\nLet's take this further. You might have noticed that I went down a line before closing the macro. This becomes handy when you want to execute it many times. In our case we have 6 lines we want to refactor. 1 line has already been altered, so we have to execute it 5 more times. As per usual with vim, you can execute an action n times by specifying a number before doing the action. Let's press `5@q` to execute the macro 5 times. And voila! Our unsafe code is now null-safe.\n\n```kt\nmLeftButton?.text = \"Left\"\nmLeftButton?.setOnClickListener(leftListener)\nmLeftButton?.visibility = View.VISIBLE\nmRightButton?.text = \"Right\"\nmRightButton?.setOnClickListener(rightListener)\nmRightButton?.visibility = View.VISIBLE\n```\n\nMacros are really satisfying to watch, if you ask me!\n\nThis is post 007 of [#100DaysToOffload](https://100daystooffload.com/).\n","frontmatter":{"title":"Using Macros in Vim","date":"2021-01-26","tags":"vim, 100DaysToOffload, guide, tech"},"tags":["vim","100DaysToOffload","guide","tech"]},"recommendedPosts":[{"slug":"2024-04-11-a-simple-search-bar","frontmatter":{"title":"A simple search bar","date":"2024-04-11","tags":"guide, note, meta, web, tech, programming"},"tags":["guide","note","meta","web","tech","programming"]},{"slug":"2024-04-04-pandoc-convert-links-to-footnotes-the-easy-way","frontmatter":{"title":"Pandoc: Convert links to footnotes (the easy way)","date":"2024-04-04","tags":"guide, note, writing, til, tech, programming, pandoc"},"tags":["guide","note","writing","til","tech","programming","pandoc"]},{"slug":"2024-04-02-fuck-trees-use-tags","frontmatter":{"title":"Fuck trees, use tags","date":"2024-04-02","tags":"note, opinion, tech"},"tags":["note","opinion","tech"]},{"slug":"2024-01-18-cost-per-request","frontmatter":{"title":"Cost per Request","date":"2024-01-18","tags":"infrastructure, aws, note, opinion, devops, tech"},"tags":["infrastructure","aws","note","opinion","devops","tech"]},{"slug":"2024-01-06-a-better-publishing-workflow-for-static-blogs","frontmatter":{"title":"A better publishing workflow for static blogs","date":"2024-01-06","tags":"guide, note, meta, writing, web, github, tech"},"tags":["guide","note","meta","writing","web","github","tech"]}]},"__N_SSG":true} |

When you're done, press `q` in normal mode again to quit your macro.\n\nComing back to my task, I would want to do the following:\n\n1. `qq` Record a macro and save it to the `q` key\n1. `_` - Jump to the beginning of the line\n1. `f!` - Find next occurrence of `!`\n1. `cw` - Change word (Delete word and enter insert mode)\n1. `?.` - Insert the new characters\n1. `<esc>` - Enter normal mode\n1. `j` - go down a line\n1. `q` - Finish macro\n\nIf everything went right, this line:\n\n```\nmLeftButton!!.text = \"Left\"\n```\n\nShould now look like this:\n\n```\nmLeftButton?.text = \"Left\"\n```\n\nand your macro should be saved under the `q` key.\n\n## Using the macro\n\nIn order to use a macro in vim, you press the `@` key, followed by the key the macro is saved under. Since our macro is defined as `q`, we'd press `@q`, and the macro is executed immediately.\n\nLet's take this further. You might have noticed that I went down a line before closing the macro. This becomes handy when you want to execute it many times. In our case we have 6 lines we want to refactor. 1 line has already been altered, so we have to execute it 5 more times. As per usual with vim, you can execute an action n times by specifying a number before doing the action. Let's press `5@q` to execute the macro 5 times. And voila! Our unsafe code is now null-safe.\n\n```kt\nmLeftButton?.text = \"Left\"\nmLeftButton?.setOnClickListener(leftListener)\nmLeftButton?.visibility = View.VISIBLE\nmRightButton?.text = \"Right\"\nmRightButton?.setOnClickListener(rightListener)\nmRightButton?.visibility = View.VISIBLE\n```\n\nMacros are really satisfying to watch, if you ask me!\n\nThis is post 007 of [#100DaysToOffload](https://100daystooffload.com/).\n","frontmatter":{"title":"Using Macros in Vim","date":"2021-01-26","tags":"vim, 100DaysToOffload, guide, tech"},"tags":["vim","100DaysToOffload","guide","tech"]},"recommendedPosts":[{"slug":"2024-04-15-beware-of-base64-encoded-strings","frontmatter":{"title":"Beware of base64 encoded strings","date":"2024-04-15","tags":"guide, note, learnings, web, til, tech, programming"},"tags":["guide","note","learnings","web","til","tech","programming"]},{"slug":"2024-04-11-a-simple-search-bar","frontmatter":{"title":"A simple search bar","date":"2024-04-11","tags":"guide, note, meta, web, tech, programming"},"tags":["guide","note","meta","web","tech","programming"]},{"slug":"2024-04-04-pandoc-convert-links-to-footnotes-the-easy-way","frontmatter":{"title":"Pandoc: Convert links to footnotes (the easy way)","date":"2024-04-04","tags":"guide, note, writing, til, tech, programming, pandoc"},"tags":["guide","note","writing","til","tech","programming","pandoc"]},{"slug":"2024-04-02-fuck-trees-use-tags","frontmatter":{"title":"Fuck trees, use tags","date":"2024-04-02","tags":"note, opinion, tech"},"tags":["note","opinion","tech"]},{"slug":"2024-01-18-cost-per-request","frontmatter":{"title":"Cost per Request","date":"2024-01-18","tags":"infrastructure, aws, note, opinion, devops, tech"},"tags":["infrastructure","aws","note","opinion","devops","tech"]}]},"__N_SSG":true} |

It is the de facto standard for when you want to run a command as a priviledged user, but that's really it. Under the hood, sudo is a very powerful tool with a lot of features. It can be used to build out complex permission-systems that span across entire clusters of servers. But all of these features come at a price: **complexity**. Last time I checked, the [source code](https://www.sudo.ws/repos/sudo) of sudo had about 330k lines of code (using cloc as a benchmark). This massive complexity plays a large role in its security.\n\nLuckily, there is a **far** more lightweight alternative to sudo called [doas](https://github.com/Duncaen/OpenDoas.git). It essentially does all the things you'd expect from sudo for your average end user. Doas is written in just over 3k lines of code, which, if you think of it, should be more than enough to provide a tool that executes a command as a priviledged user.\n\n## Setup\n\nWhile there are packages for [some distibutions](https://github.com/slicer69/doas#installation-via-packagesrepositories), I personally had trouble setting it up on arch using yay (for permission reasons, ironically). I recommend going the extra mile and building it from source, which consists of a few commands and some seconds of your time:\n\n```sh\ngit clone https://github.com/slicer69/doas\ncd doas\nmake\nsudo make install\n```\n\nNext, you will need to create a config file at `/usr/local/etc/doas.conf`. Paste the following line into it to give your user root access:\n\n```sh\npermit alice as root\n```\n\nYou obviously want to substitute alice with your username. If you have multiple users on your system, simply duplicate that line and substitute the username accordingly. Just restart your terminal window, and you should be able to run programs as root using doas instead of sudo:\n\n```sh\n➜ ~ doas id\nuid=0(root) gid=0(root) groups=0(root)\n```\n\n## Bonus: Save your muscle memory\n\nIf you still want to \"use\" sudo on your machine, you can set up a simple alias in your `.{bash|zsh|fish}rc`. This will also help with compatibility issues of some scripts, if you decide to ditch the actual sudo from your Box entirely. Just paste this line into your corresponding rc file:\n\n```\nalias sudo=\"doas\"\n```\n\n## Bonus Bonus: Passwordless authentification\n\nYou can setup doas to skip the password prompt every time you run a command with it. Simply add the `nopass` option in your doas configuration file:\n\n```sh\npermit nopass alice as root\n```\n\nI hope you found this useful!\n\nThis is post 008 of [#100DaysToOffload](https://100daystooffload.com/).\n","frontmatter":{"title":"From sudo to doas","date":"2021-01-29","tags":"linux, 100DaysToOffload, guide, tech"},"tags":["linux","100DaysToOffload","guide","tech"]},"recommendedPosts":[{"slug":"2024-04-11-a-simple-search-bar","frontmatter":{"title":"A simple search bar","date":"2024-04-11","tags":"guide, note, meta, web, tech, programming"},"tags":["guide","note","meta","web","tech","programming"]},{"slug":"2024-04-04-pandoc-convert-links-to-footnotes-the-easy-way","frontmatter":{"title":"Pandoc: Convert links to footnotes (the easy way)","date":"2024-04-04","tags":"guide, note, writing, til, tech, programming, pandoc"},"tags":["guide","note","writing","til","tech","programming","pandoc"]},{"slug":"2024-04-02-fuck-trees-use-tags","frontmatter":{"title":"Fuck trees, use tags","date":"2024-04-02","tags":"note, opinion, tech"},"tags":["note","opinion","tech"]},{"slug":"2024-01-18-cost-per-request","frontmatter":{"title":"Cost per Request","date":"2024-01-18","tags":"infrastructure, aws, note, opinion, devops, tech"},"tags":["infrastructure","aws","note","opinion","devops","tech"]},{"slug":"2024-01-06-a-better-publishing-workflow-for-static-blogs","frontmatter":{"title":"A better publishing workflow for static blogs","date":"2024-01-06","tags":"guide, note, meta, writing, web, github, tech"},"tags":["guide","note","meta","writing","web","github","tech"]}]},"__N_SSG":true} |

Then, add\nthis snippet to your docker-compose file:\n\n```yaml\napp:\n image: nextcloud\n ports:\n - 127.0.0.1:8080:80\n healthcheck:\n test:\n [\n \"CMD\",\n \"curl\",\n \"-f\",\n \"https://app-endpoint.tld\",\n \"&&\",\n \"curl\",\n \"-fsS\",\n \"-m\",\n \"10\",\n \"--retry\",\n \"5\",\n \"-o\",\n \"/dev/null\",\n \"https://healthchecks.io/ping/<UUID>\",\n ]\n interval: 60s\n timeout: 10s\n retries: 6\n```\n\nChange the first url to the url of your app. The second URL is the endpoint of\nyour healthchecks.io instance. You can obtain it from the check you configured\nearlier.\n\nThis configuration will try to ping your application and, if successful, notify\nthe healthcheck that the application is healthy. If the app is not reachable or\nthe container is down, the latter request will not be executed and your service\nis marked as \"down\".\n\nIn addition to the healthchecks of my docker containers, I also added basic\nhealthchecks to my servers cronfiles and its backup-commands.\n\nDo you have any suggestions regarding this topic?

{"pageProps":{"post":{"slug":"2021-12-24-notes-on-pruning-chinese-elms","markdownBody":"\nI recently bought a chinese elm bonsai. To keep it alive and healthy, I devoted\nsome time to learning how to properly prune it.\n\nChinese elms are very robust trees with strong growth. Even in the winter\nseason, I can prune it on a weekly basis. I just watched [this\nvideo](https://www.youtube.com/watch?v=Nsvc2Ll1X2A) which gives some helpful\ntips on pruning.\n\nI noticed that the author let the tree grow heavily to develop stronger\nbranches. Until now, I pruned the branches back to one leaf whenever it had\nabout 5 leaves. However, a branch should only be cut on its woody parts in order\nto develop more shoots, and a branch needs some growth in order to turn to wood.\n**Don't prune the branches too early**!\n\nSecondly, I thought that cutting the branches just behind a leaf would lead to\nmore growth, but I found that this is not true. The branches should be cut just\na bit above the leaf to prevent branch to die back and kill the leaf.

{"pageProps":{"post":{"slug":"2021-12-24-notes-on-pruning-chinese-elms","markdownBody":"\nI recently bought a chinese elm bonsai. To keep it alive and healthy, I devoted\nsome time to learning how to properly prune it.\n\nChinese elms are very robust trees with strong growth. Even in the winter\nseason, I can prune it on a weekly basis. I just watched [this\nvideo](https://www.youtube.com/watch?v=Nsvc2Ll1X2A) which gives some helpful\ntips on pruning.\n\nI noticed that the author let the tree grow heavily to develop stronger\nbranches. Until now, I pruned the branches back to one leaf whenever it had\nabout 5 leaves. However, a branch should only be cut on its woody parts in order\nto develop more shoots, and a branch needs some growth in order to turn to wood.\n**Don't prune the branches too early**!\n\nSecondly, I thought that cutting the branches just behind a leaf would lead to\nmore growth, but I found that this is not true. The branches should be cut just\na bit above the leaf to prevent branch to die back and kill the leaf. It could\nalso lead to the shoot coming out straight instead of angled, which is not\ndesired.\n\nLastly I learned that branches pointing upwards should most likely be pruned,\nsince they take a lot of energy that the tree could use elsewhere, which is also\npointed out in [this video](https://www.youtube.com/watch?v=93c985zOwhs).\n\nHere's a picture of my chinese elm just how I bought it.

I wanted to try alpine linux as\nthe host OS to see how it behaves as a lightweight server distro.\n\nSo far it stands up quite nicely, it has everything you'd expect from a\nlinux-based operating system. The only problem I encountered was getting BTRFS\nto work out of the box. Here are some things you should know when using BTRFS on\nAlpine linux.\n\n### Installing BTRFS\n\nInstalling BTRFS is relatively straight forward. Simply install the package and\ntell Alpine to load the module on startup:\n\n```\napk add btrfs-progs\necho btrfs >> /etc/modules\n```\n\nTo load the module right away, you can use the following command:\n\n```\nmodprobe btrfs\n```\n\n### Mounting a volume\n\nIf you try mounting a btrfs volume via your fstab, you will get an error. This\nis because BTRFS does not know about the drives yet when the filesystems are\nmounted. To work around this, you can create an OpenRC service that runs a\n`btrfs scan` to detect the drives. To do so, create a service under\n`/etc/init.d/btrfs-scan` with the following content:\n\n```sh\n#!/sbin/openrc-run\n\nname=\"btrfs-scan\"\n\ndepend() {\n before localmount\n}\n\nstart() {\n /sbin/btrfs device scan\n}\n```\n\nMake the service executable and register it:\n\n```\nchmod +x /etc/init.d/btrfs-scan\nrc-update add btrfs-scan boot\n```\n\nNow, you should be able to add the volume to your `/etc/fstab`:\n\n```\nUUID=abcdef-0055-4958-990f-1413ed1186ec /var/data btrfs defaults,nofail,subvol=@ 0 0\n```\n\nAfter a reboot, you should be able to see the drive mounted at `/var/data`.\n\n### Resources\n\n- [Nathan Parsons - \"Using BTRFS on Alpine Linux\"](https://nparsons.uk/blog/using-btrfs-on-alpine-linux)\n- [A bug report about this problem](https://gitlab-test.alpinelinux.org/alpine/aports/-/issues/9539)\n\nThis is post 023 of [#100DaysToOffload](https://100daystooffload.com/).\n","frontmatter":{"title":"BTRFS on Alpine Linux","date":"2021-12-31","tags":"linux, infrastructure, note, guide, 100DaysToOffload, homelab, tech"},"tags":["linux","infrastructure","note","guide","100DaysToOffload","homelab","tech"]},"recommendedPosts":[{"slug":"2024-04-11-a-simple-search-bar","frontmatter":{"title":"A simple search bar","date":"2024-04-11","tags":"guide, note, meta, web, tech, programming"},"tags":["guide","note","meta","web","tech","programming"]},{"slug":"2024-04-04-pandoc-convert-links-to-footnotes-the-easy-way","frontmatter":{"title":"Pandoc: Convert links to footnotes (the easy way)","date":"2024-04-04","tags":"guide, note, writing, til, tech, programming, pandoc"},"tags":["guide","note","writing","til","tech","programming","pandoc"]},{"slug":"2024-04-02-fuck-trees-use-tags","frontmatter":{"title":"Fuck trees, use tags","date":"2024-04-02","tags":"note, opinion, tech"},"tags":["note","opinion","tech"]},{"slug":"2024-01-18-cost-per-request","frontmatter":{"title":"Cost per Request","date":"2024-01-18","tags":"infrastructure, aws, note, opinion, devops, tech"},"tags":["infrastructure","aws","note","opinion","devops","tech"]},{"slug":"2024-01-06-a-better-publishing-workflow-for-static-blogs","frontmatter":{"title":"A better publishing workflow for static blogs","date":"2024-01-06","tags":"guide, note, meta, writing, web, github, tech"},"tags":["guide","note","meta","writing","web","github","tech"]}]},"__N_SSG":true} |

In it, [Thomas Rampelberg](https://saunter.org/) makes an analogy that\nI think is worth sharing:\n\n> \"[...] Kubernetes is really a domain-specific database. And you need to look at it\n> that way. The YAML is literally writing a select statement or an insert\n> statement for a database. That's what the YAML is. And it's awesome that it is\n> already configured for how it is. And it's awesome that it's got a schema. But\n> the YAML is you writing an insert statement into Kubernetes. [...]\"\n\nThe Kubernetes API abstracts two types of states: desired state and actual\nstate. Whenever you apply a manifest, you update the _desired state_ of the\ncluster, just like you do in a regular, non domain-specific database like\nPostgreSQL or Redis. Kubernetes then frequently compares the desired state with\nthe _actual_ state of the cluster. If they don't match, Kubernetes will do\nwhatever it does to match these two states. Usually, this data is persisted\nusing a key-value database like [etcd](https://etcd.io/) running in a cluster,\nthough one could theoretically also hook up an external MySQL or Postgres\ndatabase for this purpose.\n\nI found this great diagram by [Tim\nDowney](https://downey.io/blog/desired-state-vs-actual-state-in-kubernetes/),\nshowing an oversimplified analogy of this pattern:\n\n\n\nYou _insert_ your desired state into the system, and the system adjusts the\nactual state to match the desired state.

In it, [Thomas Rampelberg](https://saunter.org/) makes an analogy that\nI think is worth sharing:\n\n> \"[...] Kubernetes is really a domain-specific database. And you need to look at it\n> that way. The YAML is literally writing a select statement or an insert\n> statement for a database. That's what the YAML is. And it's awesome that it is\n> already configured for how it is. And it's awesome that it's got a schema. But\n> the YAML is you writing an insert statement into Kubernetes. [...]\"\n\nThe Kubernetes API abstracts two types of states: desired state and actual\nstate. Whenever you apply a manifest, you update the _desired state_ of the\ncluster, just like you do in a regular, non domain-specific database like\nPostgreSQL or Redis. Kubernetes then frequently compares the desired state with\nthe _actual_ state of the cluster. If they don't match, Kubernetes will do\nwhatever it does to match these two states. Usually, this data is persisted\nusing a key-value database like [etcd](https://etcd.io/) running in a cluster,\nthough one could theoretically also hook up an external MySQL or Postgres\ndatabase for this purpose.\n\nI found this great diagram by [Tim\nDowney](https://downey.io/blog/desired-state-vs-actual-state-in-kubernetes/),\nshowing an oversimplified analogy of this pattern:\n\n\n\nYou _insert_ your desired state into the system, and the system adjusts the\nactual state to match the desired state. In the case of thermostats the state is\na temperature. In Kubernetes, it's [resource\nobjects](https://kubernetes.io/docs/concepts/overview/working-with-objects/kubernetes-objects/)\n\nThis is post 037 of [#100DaysToOffload](https://100daystooffload.com/).\n","frontmatter":{"title":"Kubernetes is a domain specific database","date":"2022-09-22","tags":"note, 100DaysToOffload, infrastructure, kubernetes, tech"},"tags":["note","100DaysToOffload","infrastructure","kubernetes","tech"]},"recommendedPosts":[{"slug":"2024-04-15-beware-of-base64-encoded-strings","frontmatter":{"title":"Beware of base64 encoded strings","date":"2024-04-15","tags":"guide, note, learnings, web, til, tech, programming"},"tags":["guide","note","learnings","web","til","tech","programming"]},{"slug":"2024-04-11-a-simple-search-bar","frontmatter":{"title":"A simple search bar","date":"2024-04-11","tags":"guide, note, meta, web, tech, programming"},"tags":["guide","note","meta","web","tech","programming"]},{"slug":"2024-04-04-pandoc-convert-links-to-footnotes-the-easy-way","frontmatter":{"title":"Pandoc: Convert links to footnotes (the easy way)","date":"2024-04-04","tags":"guide, note, writing, til, tech, programming, pandoc"},"tags":["guide","note","writing","til","tech","programming","pandoc"]},{"slug":"2024-04-02-fuck-trees-use-tags","frontmatter":{"title":"Fuck trees, use tags","date":"2024-04-02","tags":"note, opinion, tech"},"tags":["note","opinion","tech"]},{"slug":"2024-01-18-cost-per-request","frontmatter":{"title":"Cost per Request","date":"2024-01-18","tags":"infrastructure, aws, note, opinion, devops, tech"},"tags":["infrastructure","aws","note","opinion","devops","tech"]}]},"__N_SSG":true} |

I used to self-host a lot of my tools, but after some time the burden of maintaining those tools made me switch to hosted alternatives.\n\nHowever, there are a few projects that I stuck with over the years, and which I think deserve a deep appreciation.\n\n## Miniflux\n\n[Miniflux](https://miniflux.app/) is a very minimal, self-hostable RSS reader. It's been rock-solid since they day I started using it. The data for the application entirely lives In a Postgres database, which makes migrating the application to new infrastructure setups an absolute breeze. I've been meaning to support the author for quite some time now, but the cost of maintaining an instance yourself is basically zero, so I've yet to find the time to switch to their paid hosted instance.\n\n## Plausible Analytics\n\n[Plausible](https://plausible.io/) is another tool that just keeps on running. I haven't had any issues with it whatsoever, and I can't remember the last time I had to do a manual intervention. Just like Miniflux, there's a paid instance, which supports the author, and just like Miniflux, the software is so good that I haven't had a reason to switch to it yet. Oh, the irony.\n\n## BirdsiteLIVE\n\nWhile my instance of [BirdsiteLIVE](https://birdsite.slashdev.space/) is currently in a bad shape, this is not at all the fault of the software. There are limitations to the amount of Twitter API requests you can make, and I did a poor job managing the users on that instance. It's currently very overloaded and just very few tweets make it through. I will have to set aside some time to fix this, but the software itself has been rock solid since the day I started using it.\n\n## Synapse (Matrix)\n\nI was hesitant to mention [Matrix](https://matrix.org/) on this list. I had my ups and downs with Synapse (their Python implementation of a Matrix server), but the fact that my instance is still running after multiple infrastructure transitions and even a migration from SQLite to Postgres says something about the quality of the software. I have a feeling that Synapse is fairly resource-hungry, but if you feed it with enough RAM and disk, it will keep running indefinitely.\n\n## Homeassistant\n\nYou can throw [Homeassistant](https://www.home-assistant.io/) on a Raspberry Pi and everything works out of the gate. I even migrated my instance from a RPi 3 to a RPi 4 via their backup and restore functionality. It's absolutely flawless.\n\n## Dead projects\n\nI think it's fair to also mention the software that I no longer self-host.\n\n### E-Mail\n\nJust don't roll your own email.\n\n### Mastodon\n\nToo power hungry for my taste. No easy way to host inside docker, which made it a pain to keep running. I'm very happy with [Fosstodon](https://fosstodon.org/), and don't see a reason to switch to a self-hosted instance any time soon.\n\n### FreshRSS\n\nI tried replacing Miniflux once, but failed. Nothing beats Miniflux.\n\n### Prometheus + Grafana\n\nMonitoring **_inside_** your infra works until the infra goes down, at which point you're essentially driving blindfolded.

I added a simple\n[guestbook](/guestbook) to this site, which is open to receive pull requests.\nI'd love to hear from you!\n\nThis is post 040 of [#100DaysToOffload](https://100daystooffload.com/).\n","frontmatter":{"title":"A simple guestbook","date":"2022-10-05","tags":"note, meta, 100DaysToOffload, guide"},"tags":["note","meta","100DaysToOffload","guide"]},"recommendedPosts":[{"slug":"2024-04-15-beware-of-base64-encoded-strings","frontmatter":{"title":"Beware of base64 encoded strings","date":"2024-04-15","tags":"guide, note, learnings, web, til, tech, programming"},"tags":["guide","note","learnings","web","til","tech","programming"]},{"slug":"2024-04-11-a-simple-search-bar","frontmatter":{"title":"A simple search bar","date":"2024-04-11","tags":"guide, note, meta, web, tech, programming"},"tags":["guide","note","meta","web","tech","programming"]},{"slug":"2024-04-07-five-years-of-blogging","frontmatter":{"title":"Five Years of Blogging","date":"2024-04-07","tags":"note, books, writing, meta"},"tags":["note","books","writing","meta"]},{"slug":"2024-04-04-pandoc-convert-links-to-footnotes-the-easy-way","frontmatter":{"title":"Pandoc: Convert links to footnotes (the easy way)","date":"2024-04-04","tags":"guide, note, writing, til, tech, programming, pandoc"},"tags":["guide","note","writing","til","tech","programming","pandoc"]},{"slug":"2024-01-06-a-better-publishing-workflow-for-static-blogs","frontmatter":{"title":"A better publishing workflow for static blogs","date":"2024-01-06","tags":"guide, note, meta, writing, web, github, tech"},"tags":["guide","note","meta","writing","web","github","tech"]}]},"__N_SSG":true} |

Coming from a Node.js-driven world where every human and their grandmother has a blog post about containerizing your application, it was very interesting to see where PHP differs to other applications.\r\n\r\nOne major gotcha for me was that PHP code is executed on **request-time**, meaning a new process is spawned for each incoming request. Most other languages have dedicated runtimes that handle incoming requests. This unique approach is very flexible and scalable, but it comes with the implication that there is a **separate webserver** that calls into the PHP interpreter when it needs to.\r\n\r\nIn Node.js (and most other languages), you can \"just run the app\", as demonstrated by this Dockerfile:\r\n\r\n```dockerfile\r\nFROM node:18.14.2-alpine3.17 AS build\r\n\r\nWORKDIR /usr/src/app\r\n\r\nCOPY package*.json ./\r\n\r\nRUN npm ci\r\n\r\nCOPY . .\r\n\r\nEXPOSE 3000\r\n\r\nCMD [ \"node\", \"server.js\" ]\r\n```\r\n\r\nPHP on the other side is rarely used on its own.

The PHP maintainers know that adding a webserver alongside PHP is a very common pattern, so most of the variants of the image ship with a webserver. In this example I'm using Apache, but we might as well use NGINX or some other webserver.

{"pageProps":{"post":{"slug":"2023-03-10-debugging-ecs-tasks","markdownBody":"\r\nI just had to debug an application on AWS ECS. The whole procedure is documented in more detail in the [documentation](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-exec.html), but I think it's beneficial (both for my future self and hopefully to someone out there) to write down the proccess in my own words.\r\n\r\nFirst of all, you need access to the cluster via the [CLI](https://aws.amazon.com/de/cli/). In addition to the CLI, you need the [AWS Session Manager plugin for the CLI](https://docs.aws.amazon.com/systems-manager/latest/userguide/session-manager-working-with-install-plugin.html).

During the development, I learned a lot about designing components to be resilient and scalable. Here are some key takeaways.\r\n\r\nOne of the most critical components of a resilient infrastructure is redundancy. On AWS, you place your components inside a \"region\". This could be `eu-central-1` (Frankfurt) or `us-east-1` (North Virgina), etc. To further reduce the risk of an outage, each region is divided into multiple [Availability Zones](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.RegionsAndAvailabilityZones.html) (AZs). The AZs of a region are usually located some distance apart from each other. In case of a flood, a fire or a bomb detonating near one AZ, the other AZs should in most cases still be intact. You should have at least two, preferably three replicas of each component across multiple availability zones in a region. By having replicas of your components in different availability zones, you reduce the risk of downtime caused by an outage in a single availability zone.\r\n\r\nAnother way to ensure scalability and resilience for your database is to use [Aurora Serverless v2](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-serverless-v2.html). This database service is specifically designed for scalable, on-demand, and cost-effective performance. The database scales itself up or down based on the workload, which allows you to automatically and dynamically adjust the database capacity to meet the demand of your application, ensuring that your application is responsive and performs well without the need for manual intervention. Adding Serverless instances to an existing RDS cluster is also a seemless proccess.\r\n\r\nIn addition to switching to Aurora Serverless v2, using read replicas for cache and database in a separate availability zone can act as a hot standby without extra configuration. Keep in mind that read replicas are only utilized by explicitly using the read-only endpoint of a cluster. But even if you're only using the \"main\" cluster endpoint (and therefore just the primary instance), a read replica can promote itself to the primary instance in case of a fail over, which drastically reduces downtime.\r\n\r\nWhen using Amazon Elastic Container Service (ECS), use Fargate as opposed to EC2 instances. Fargate is a serverless compute engine for containers that allows you to run containers without having to manage the underlying infrastructure. It smartly locates instances across availability zones, ensuring that your application is always available.\r\n\r\nIn conclusion, you should always ensure that there are more than one instance of a component in your infrastructure. There are also services on AWS that abstract away the physical infrastructure (Fargate, S3, Lambda) and use a multi-AZ pattern by default.\r\n\r\n---\r\n\r\nThis is post 061 of [#100DaysToOffload](https://100daystooffload.com/).\r\n\r\n","frontmatter":{"title":"Designing resilient cloud infrastructure","date":"2023-03-30","tags":"100DaysToOffload, infrastructure, aws, guide, note, learnings, tech"},"tags":["100DaysToOffload","infrastructure","aws","guide","note","learnings","tech"]},"recommendedPosts":[{"slug":"2024-04-11-a-simple-search-bar","frontmatter":{"title":"A simple search bar","date":"2024-04-11","tags":"guide, note, meta, web, tech, programming"},"tags":["guide","note","meta","web","tech","programming"]},{"slug":"2024-04-10-beating-elden-ring","frontmatter":{"title":"Beating Elden Ring","date":"2024-04-10","tags":"note, learnings, life, review, gaming"},"tags":["note","learnings","life","review","gaming"]},{"slug":"2024-04-04-pandoc-convert-links-to-footnotes-the-easy-way","frontmatter":{"title":"Pandoc: Convert links to footnotes (the easy way)","date":"2024-04-04","tags":"guide, note, writing, til, tech, programming, pandoc"},"tags":["guide","note","writing","til","tech","programming","pandoc"]},{"slug":"2024-04-02-fuck-trees-use-tags","frontmatter":{"title":"Fuck trees, use tags","date":"2024-04-02","tags":"note, opinion, tech"},"tags":["note","opinion","tech"]},{"slug":"2024-01-18-cost-per-request","frontmatter":{"title":"Cost per Request","date":"2024-01-18","tags":"infrastructure, aws, note, opinion, devops, tech"},"tags":["infrastructure","aws","note","opinion","devops","tech"]}]},"__N_SSG":true} |

I just had a fruitful conversation with the DevOps lead of a client, and they phrased this role in a very fitting way.\r\n\r\n> A DevOps Engineer doesn't push the button, they enable the developers to push the button themselves.\r\n\r\nTo me this role is fascinating, since it touches so many different aspects of software delivery.\r\n\r\n---\r\n\r\nThis is post 065 of [#100DaysToOffload](https://100daystooffload.com/).\r\n","frontmatter":{"title":"The role of a DevOps Engineer","date":"2023-04-22","tags":"100DaysToOffload, note, practices, devops, tech"},"tags":["100DaysToOffload","note","practices","devops","tech"]},"recommendedPosts":[{"slug":"2024-04-15-beware-of-base64-encoded-strings","frontmatter":{"title":"Beware of base64 encoded strings","date":"2024-04-15","tags":"guide, note, learnings, web, til, tech, programming"},"tags":["guide","note","learnings","web","til","tech","programming"]},{"slug":"2024-04-11-a-simple-search-bar","frontmatter":{"title":"A simple search bar","date":"2024-04-11","tags":"guide, note, meta, web, tech, programming"},"tags":["guide","note","meta","web","tech","programming"]},{"slug":"2024-04-04-pandoc-convert-links-to-footnotes-the-easy-way","frontmatter":{"title":"Pandoc: Convert links to footnotes (the easy way)","date":"2024-04-04","tags":"guide, note, writing, til, tech, programming, pandoc"},"tags":["guide","note","writing","til","tech","programming","pandoc"]},{"slug":"2024-04-02-fuck-trees-use-tags","frontmatter":{"title":"Fuck trees, use tags","date":"2024-04-02","tags":"note, opinion, tech"},"tags":["note","opinion","tech"]},{"slug":"2024-01-30-to-prove-something-is-true-try-disproving-it-first","frontmatter":{"title":"To prove something is true, try disproving it first","date":"2024-01-30","tags":"note, quote, practices, til, science"},"tags":["note","quote","practices","til","science"]}]},"__N_SSG":true} |

{"pageProps":{"post":{"slug":"2023-06-01-single-page-applications-on-github-pages","markdownBody":"\nMy latest project, [sendpasswords.net](https://sendpasswords.net/) is a [Single Page Application](https://developer.mozilla.org/en-US/docs/Glossary/SPA) deployed on GitHub Pages.\n\nGitHub Pages is configured in a way to host static HTML files without any bells and whistles. This means that if you try to fetch a document that's *not* the index, for example `/foo`, the server will try to load the file with that name. \n\nBy nature, SPAs only consist of a single HTML entry point (`index.html` in most cases). It's responsible for routing the user to the correct page if there are multiple paths. And here's the crux: if the user tries to load `/foo`, he will not land at the SPA entry point. Instead, he will see a `404` error.\n\n## The solution\n\nA `404` response will automatically return a file called `404.html`, which we can use to our advantage. After building the application, simply copy the `index.html` to `404.html`, as demonstrated by [this commit](https://github.com/garritfra/sendpasswords.net/commit/66bdb68c229a3ac3386f7816a746155e658eb586). This will use `index.html` to serve the application on the root level, and `404.html` to load *the same app* if the page doesn't exist as a file.

{"pageProps":{"post":{"slug":"2023-06-01-single-page-applications-on-github-pages","markdownBody":"\nMy latest project, [sendpasswords.net](https://sendpasswords.net/) is a [Single Page Application](https://developer.mozilla.org/en-US/docs/Glossary/SPA) deployed on GitHub Pages.\n\nGitHub Pages is configured in a way to host static HTML files without any bells and whistles. This means that if you try to fetch a document that's *not* the index, for example `/foo`, the server will try to load the file with that name. \n\nBy nature, SPAs only consist of a single HTML entry point (`index.html` in most cases). It's responsible for routing the user to the correct page if there are multiple paths. And here's the crux: if the user tries to load `/foo`, he will not land at the SPA entry point. Instead, he will see a `404` error.\n\n## The solution\n\nA `404` response will automatically return a file called `404.html`, which we can use to our advantage. After building the application, simply copy the `index.html` to `404.html`, as demonstrated by [this commit](https://github.com/garritfra/sendpasswords.net/commit/66bdb68c229a3ac3386f7816a746155e658eb586). This will use `index.html` to serve the application on the root level, and `404.html` to load *the same app* if the page doesn't exist as a file. Whether the `index.html` is needed if there's already a `404.html` is up to you. I left it in to make clear that this is just a workaround.\n\nThis is a [well known](https://stackoverflow.com/a/69308662/9046809) workaround, but I wanted to bring some extra awareness to it, since it's a problem I ran into a couple of times so far.

{"pageProps":{"post":{"slug":"2023-09-29-undo-on-mobile-phones","markdownBody":"\nMaybe this is just wishful thinking from someone who grew up in front of a physical keyboard, but I sometimes wish that my phone had a global \"undo\" button.\n\nI'm sure there's a reason why phones have evolved away from having such a feature, but sometimes, especially when editing text, it would be very useful to \"just hit ctrl-z\", or whatever it would be on a phone. Some apps do have such a button, but they explicitly had to place it there and craft a feature around it.\n\nI can imagine that Android and other OSes are capable of exposing an \"undo\" API that apps can implement to make this easier.

Some apps do have such a button, but they explicitly had to place it there and craft a feature around it.\n\nI can imagine that Android and other OSes are capable of exposing an \"undo\" API that apps can implement to make this easier. A gesture well known to the user, similar to the \"back\" button or gesture on Android, would trigger an undo. For text, apps probably won't even have to implement anything.

My personal projects live in a `~/sources` directory. All my work projects live in `~/work`. This is the first level.\r\n\r\nLevel 2 is the client, e.g. `~/work/client1`. Naturally, level 3 is the project repository: `~/work/client1/foo-api`.\r\n\r\nThis is how my work directory is organized:\r\n\r\n```\r\n/Users/garrit/work\r\n├── client1\r\n│ ├── foo-api\r\n│ ├── foo-ios\r\n│ └── foo-android\r\n└── client2\r\n ├── bar-ios\r\n └── bar-middleware\r\n```\r\n\r\nNow, say that `client2` demands that we commit with a different identity than our default work email. Besides that, you probably also have a personal email address for your own projects. How do you manage that?\r\n\r\n## .gitconfig includes\r\n\r\nThe global configuration file for Git is `~/.gitconfig`. If you've ever set a parameter like `git config user.name \"Foo Bar\"`: this is where it ended up.\r\n\r\nOne awesome feature of the .gitconfig file is that you can **conditionally include other config files**, and this is what does the trick. Here's my `~/.gitconfig` file:\r\n\r\n```ini\r\n[user]\r\n name = Garrit Franke\r\n email = garrit@slashdev.space\r\n\r\n[includeIf \"gitdir:~/work/\"]\r\n path = ~/.gitconfig-work\r\n\r\n[includeIf \"gitdir:~/work/client2/\"]\r\n path = ~/.gitconfig-client2\r\n\r\n[includeIf \"gitdir:~/sources/\"]\r\n path = ~/.gitconfig-personal\r\n\r\n# ...\r\n```\r\n\r\nBy default, my name and email are always set to my personal identity. I also store some other global settings here, but those are not relevant for this post. If the repository is located inside the `~/work` directory, a file named `~/.gitconfig-work` is included. This is just another gitconfig file. This is what that looks like in my case:\r\n\r\n```ini\r\n[user]\r\n name = Garrit Franke\r\n signingkey = 12345678\r\n email = garrit@work.de\r\n\r\n[commit]\r\n gpgsign = true\r\n```\r\n\r\nI hope you'll see where this is going. For every identity, you keep a separate gitconfig file and include it in the main `~/.gitconfig`. Crucially, this requires you to organize your repositories grouped by client.\r\n\r\nThis trick has simplified my project onboarding quite a bit.
