Vim has a handy feature to format text with gq. You can use it in visual mode, give it a motion, or if you give it gqq it will format the current line. I use this quite often while writing in markdown, I do not use softwraps in vim, so gqq quickly formats my current line into a paragraph. Once I have done this for a single line one time I typically switch to the motion for around paragraph gqap to format the whole paragraph and not just the current line.

A slug is the part of the url that comes after the domain. Commonly matches the file name of a markdown file many blogging systems. These are typically human readable, unique identifiers for pages within the site.

Wikilinks are a core concept within obsidian to link to documents by Slug wrapped in double square brackets. These are commonly used within wiki site generators.

Obsidian gives you a keybinding alt+enter to go to that file, but if it does not exist it will create the file for you in the root of the project. It’s a nice way to quickly make new documents.

It was not obvious to me, but if you have a wikilink such as Trying Obsidian, you can jump to the file in obsidian, just like you can with lsp go to definition, the keybinding is alt + enter.

Very inspiring video Jason, these people faced adversity and crushed it. The market is so hard right now, its not easy to get a job, move around, and recover from a layoff. Everyone in this video just showed that you can make it in this industry right now, you just have to be willing to work harder than the rest. The bar is raising, a lot of great people are already putting in hard work to make it.

Community is Key, Theo mentioned that a lot of the companies he works with don’t even post openings, they go to their community first and are often filling spots through lower risk community hires.

Thor always comes in hard with fire takes in his shorts. Especially if you are early in our career take this in. If you dont yet have kids, but plan to, double take this in.

I’ve long used copier to create all of my posts for my blog, and it works really well for my workflow. I think of a title, call a template, and give it a title. out of the box obsidian did not seem to work this way. It seems like it wants me to right click a file tree and make a new file using the tree, this is not my jam.

Here is what I came up with to replace my til template.

I’m giving obsidian a go as an editor for my blog and one of the main things I want to fix in my workflow is the ability to quickly drop in images. on first look through the community plugins I found Image Converter. I set it up to convert to webp and drop them in a git submodule. I may make it something other than a git repo in the future, but I’ve learned that adding images to my blog repo quickly makes it heavy and hard to clone on other machines.

Once the images are there they are pushed and deployed as their own site to cloudflare pages. I made a quick edit to my

Docker no Docker, what!!!

So fly.io uses Dockerfiles to deploy your app, but no docker. They use containerd to download your docker images into firecracker microvms to run your app. Firecracker is the same tech that runs aws lambda functions.

Fascinating short post on the beans under the hood at fly.io and how they scale your app globally.

Damn Johnny is always such a positive vibe, just getting steamrolled by this braille shit. WTF are these brand sleeping on. Happy to hear that Andy and Brian are supporting him well.

Also kinds shows what shoes are good when he goes to buy shoes cause no one will send him any and he goes with Etnies.
