GitHub - svenstaro/miniserve: 🌟 For when you really just want to serve some files over HTTP right now! 🌟 For when you really just want to serve some files over HTTP right now! - svenstaro/miniserve GitHub · github.com [1] miniserve is a sweet http server, replacement for python -m http.server. It’s fast, runs off a small binary, but why would I want to use it over something that already exists on most machines, because it includes a bunch of features like qr codes, pretty themes, and uploads. I’ve used python -m http.server many times to transfer files from one machine to another in a pinch, like at a family members house. But what if they have an android, windows, or something not easy to get a python repl running on, you can run miniserve and upload from their device rather than hosting from their device.

Inside 22,734 Steam games About a year ago I blogged about games that use curl. In that post I listed a bunch of well-known titles I knew use curl and there was a list of 136 additional games giving credit to curl. Kind of ... daniel.haxx.se · daniel.haxx.se [1] Interesting to see that curl is used in so many places.

No offense to anyone working on wget, but generally I use it out of lazyness or something wierd is happening and I am looking for a second opinion.

I’ve started leaning in on kubernetes kustomize to customize my manifests per deployment per environment. Today I learned that it comes with a diff command. kubectl diff -k k8s/overlays/local You can enable color diffs by using an external diff provider like colordiff. export KUBECTL_EXTERNAL_DIFF="colordiff -N -u" You might need to install colordiff if you don’t already have it. sudo pacman -S colordiff sudo apt install colordiff Now I can try out kustomize changes and see the change with kustomize diff.

Animal well does not let you remap keys, and really doesn’t even inform you that it is keyboard compatible. I had to play around and discover the keymap, which can be a bit tricky on a 40% board. This is what I found. - wasd - move - space - jump / a - enter - interact / b - x - throw - c - inventory - 1 - left item / rb - 2 - open item menu / triangle - 3 - right item / lb

Email Address Obfuscation Hide email addresses from bots while keeping them visible to visitors. Cloudflare Docs · developers.cloudflare.com [1] I recently started seeing email-decode.min.js show up on my blog posts, and I wondered what the heck ? I didn’t put it there. Turns out that cloudflare put it there from pages to safely serve email addresses for me. inspecting the page without js running we can see that the mailto email is swapped out for email protected.

Background Tasks - FastAPI FastAPI framework, high performance, easy to learn, fast to code, ready for production fastapi.tiangolo.com [1] fastapi [2] comes with a concept of background tasks which are functions that can be ran in the background after a function has been ran. This is handy for longer running functions that may take some time and you want to have fast response times. Here is an example from the docs from fastapi import BackgroundTasks, FastAPI app = FastAPI() def write_notification(email: str, message=""): with open("log.txt", mode="w") as email_file: content = f"notification for {email}: {message}" email_file.write(content) @app.post("/send-notification/{email}") async def send_notification(email: str, background_tasks: BackgroundTasks): background_tasks.add_task(write_notification, email, message="some notification") return {"message": "Notification sent in the background"} Note This post is a thought [3].

Client Challenge pypi.org [1] markdown it py running in rust claims to be 20x faster. I’ll definitely look into this if markdown it py is ever a bottleneck in my performance.

[1] diskcache has a peekitem method that allows you to lookup the expire_time of a cached item without changing it. I recently used this to implement debounce for fastapi [2] background tasks with multiple workers running. since all the workers I care about are on the same machine, but running in different processes diskcache was a great option. All workers have access to the same disk, but not the same variables in memory. Note This post is a thought [3].

Since they are all running on the same machine with access to the same disk, diskcache is a good choice What I need # [3] - check if a job is running - automatically expire jobs Less infrastructure complexity # [4] My brain first went to thinking I needed another service like redis running alongside fastapi for this, then it hit me that...
