- Theo does a fantastic history of serverless here. Kubernetes shit # [1] Theo can’t have an infra video without shitting on k8s. Specifically people who have never touched k8s pushing fear of k8s to large audiences of people who have never touched k8s. If you are a webdev who solely lives in webdev space and never touches as much as a dockerfile listen to him. If you touch infra at all try it before you take his opinion at face value. [2] Serverless shines in high variance # [3] If you plan on having traffic spikes 10x your regular traffic for something like black friday, serverless might be right for your use case. stateless programming # [4] He argues that targeting a stateless deployment of serverless leads to better code. I’d like to see more examples here. Maybe most of the code bases I work on already do this. I’ve never targeted a serverless deployment, but I’ve targeted horizontally scaled deployments many times and they feel like they have the same targets. For instance if I spin up 8 pods for my application or uvicorn with 3 workers I have to target statelessness, all of the state must live in the database and cannot live in memory. Even if I target 1 instanc...

- Lane from boot.dev madde this fantastic video about serving files on the internet. It has me wondering if I need to rethink a few of my things that I have built. I have a few things I am serving media from, but I have very aggressive cloudflare cache rules on them, so each file should only be uploaded about once per year. My problem going straight out of minio right now is how do i set headers for cache control on it. If I can’t set the cache control and everything is coming out of minio this does not solve my problems. --- I went back and played with presigned urls and you can in fact control and set response headers, this is definitely the way and I have been wrong.

The beautiful sentence that is the web A metaphor for the building blocks of web development. cassidoo.co [1] Nicely worded Cassidy! Javascript can be too much, it can bog down low powered devices, we can ship so much that its untenable on poor connections. It can be argued that its a bad language and putting it on the server is a mistake, but it brings sites to life. It makes it possible to extend the static nature of html [2]/css with just a little special spice only your site needs. I’d add to the argument that a lot of js should go away over time. Over time libraries such as jquery have fallen out of use, not because they are bad, or have been replaced by new libraries, but because the browser has adopted most of the functionality that jquery brought. As a primarily python dev I’d really like to see htmx [3] die a very similar graceful death. There have been several iterations on this idea, and the crux of it is very similar, give the ability to use HTTP verbs right inside html with some instruction of when to apply them and what to apply them to. No js should not go away, it never will, we will always find new patterns that the browser should take, sites will always n...

How to configure base url for all requests using HTMX? Given example from the docs <button hx-post="/clicked" hx-trigger="click" hx-target="#parent-div" hx-swap="outerHTML"> Click... Stack Overflow · stackoverflow.com [1] Today I learned how to configure the baseurl for htmx [2] using the tag. This is pretty handy to be able to configure different baseurls. <base href="<scheme>://<netloc>/api/v1/"> <button hx-post="clicked" hx-trigger="click" hx-target="#parent-div" hx-swap="outerHTML"> Click Me! </button> References: [1]: https://stackoverflow.com/questions/69456875/how-to-configure-base-url-for-all-requests-using-htmx [2]: /htmx/

Addy Osmani (@addyosmani.bsky.social) Tip: Chrome DevTools can override the content of Fetch/XHR requests! Useful for mocking APIs without waiting on backend changes. Bluesky Social · bsky.app [1] WTF, you can just change a server response from devtools and update a vuejs app? Just tried with htmx [2], and my GET requests are not showing up in the sources tab. I’ll keep this in my back pocket for next time I’m supporting a vuejs app though. References: [1]: https://bsky.app/profile/addyosmani.bsky.social/post/3lei5jhkgdk2k [2]: /htmx/

- Great list of 4 tips for running fastapi applications. Keep routes small # [2] Fat routers with all of the logic built in makes them hard to test, hard to refactor, causes lots of duplication, and makes it hard to reuse the business logic code later in something like a cli application. Deploy Early # [3] I really like this advice! He reccommends deploying as early as you can get a healthcheck live in your application. I’ve found too many times developers build something that is really hard, or impossible to deploy, when if they had tried to deploy early they would have spotted some easy to fix issues. This is less important if you are building out of a template that your team commonly deploys from, but very important with new patterns. https://youtu.be/XlnmN4BfCxw?si=ks1wvmgDyoQLgrv2&t=1093 [4] References: [1]: /fastapi/ [2]: #keep-routes-small [3]: #deploy-early [4]: https://youtu.be/XlnmN4BfCxw?si=ks1wvmgDyoQLgrv2&amp;t=1093

- This was an eye opening video into agentic editing workflows. setting rules # [1] Dfferent ai tools use different rules files, windsurf uses .windsurfrules. [2] testing out rules # [3] Test out your rules file by having it say something at the beginning of the output to verify that the rules are being applied correctly. [4] First line # [5] He suggests to use this key rule for debugging purposes, otherwise you are guessing to what rules if any it is following. Every time you choose to apply a rule(s), explicitly state the rule(s) in the output. You can abbreviate the rule description to a single word or phrase.

- This is a pretty great episode talking shop with typecraft. They talk setups, cameras, content creation. I found them talking about their linux setups particularly interesting. Dax talked about his flow from building his own machines to using reliablesite.com. tmux default leader # [1] Dax hates on c-a, both typecraft and dax use c-s, which normally freezes a terminal, we can all agree that is useless. I use the default c-b, it seems fine for me. type crafts setup # [2] - Ubuntu - Ghosty - Tmux - Nvim - Ruby Selling coffee without a web front end # [3] Dax talks about terminal.shop and how they originally planned to have a web front end, but after they had so much success they stuck with it. now they are leaning harder into it and are building out integrations with a bunch of languages and an api, but no front end.

Add a healthcheck to your FastAPI app | Nic Payne I'm building a few FastAPI apps to throw in docker and run on my homelab... I wanted to add healthchecks and here's a simple way to do it Make sure to pype.dev [1] Nice example of adding a healthcheck to fastapi [2], and integrating it with docker. Don’t forget to include curl in the install, nice touch. References: [1]: https://pype.dev/add-a-healthcheck-to-your-fastapi-app [2]: /fastapi/

Hurl - Run and Test HTTP Requests Hurl, run and test HTTP requests with plain text and curl. Hurl can run fast automated integration tests. hurl.dev [1] Hurl was mentioned by @gerhard [2] on the latest changelog and Friends [3]. Looks like a feature rich easy to use testing tool that is tested via what looks like a config file. Hurl is a command line tool that runs HTTP requests defined in a simple plain text format. It can chain requests, capture values and evaluate queries on headers and body response. Hurl is very versatile: it can be used for both fetching data and testing HTTP sessions. Hurl makes it easy to work with HTML [4] content, REST / SOAP / GraphQL APIs, or any other XML / JSON based APIs.
