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. I often think of things like games being so windows centric and curl being so linux centric I don’t even think of these things crossing paths as much as they do. Note This post is a thought [2].

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].

markdown-it-pyrs A Python interface for markdown-it.rs, using Rust for blazingly fast Markdown parsing ⚡️ PyPI · 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. At first glance it appears that plugins are written in rust not python, and there is no admonition plugin, so I’ll keep my eye on it for now, but I can’t use it. Note This post is a thought [2].

[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].

And each fastapi worker will be running in a different process so I cannot keep track of work in memory, I have to do it in a distributed fashion. 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...

Yesterday I realized that I have overlooked the default installation method of the sealed secrets controller for kubernetes kubeseal [1] this whole time an jumped straight to the helm section. I spun up a quick kind cluster [2] and had it up quickly. I can’t say this is any better or worse than helm as I have never needed to customize the install. According to the docs you can customize it with [[ kustomize ]] or helm. # option if you don't have a cluster try with kind kind create cluster curl -L https://github.com/bitnami-labs/sealed-secrets/releases/download/v0.27.0/controller.yaml > controller.yaml kubectl apply -f controller.yaml References: [1]: /kubernetes-kubeseal/ [2]: /kind-cluster/
