Today I Learned

andydunstall has done a fantastic job with piko. Highly recommend taking a look.

An open-source alternative to Ngrok, designed to serve production traffic and be simple to host (particularly on Kubernetes)

2024 has been a wild year for infra with going “back” to on prem being made popular by @dhh. Well it looks like ahrefs saw right through the cloud trends an decided to ride the anti cloud train until it came back around to the station.

Being just a bit critical of the article it is impossible to get an apples to apples without actually running something of this scale and spending too much to find out. I cant imagine raw ec2 and ebs being the cheapest route into aws. They used no serverless tech in their article, but I digress, because I like this own your shit and build good product train.

What about People?!

This follow up does dive into the typical gut reaction that people cost a lot of money, you must account for them. You see when you hire people who are actually good at what they do, and run lean a lot of cost goes away, you have levels of management that disappear, levels of tooling that don’t need to exist, departments of IT don’t need to exist.

...

When using justfiles each line is ran separately from the last, unless you specify the file to be ran by something other than just such as bash. If you want variables to persist you need to set a shebang.

Also if you are using your script i a way that you want it to exit when it fails you need to set -e and -o pipefail. This is critical if you are thinking about using just for production scripts like ci/cd. I’ve hit too bugs where ci passes, but no artifacts were created issues for this exact reason.

This is a dope ass cheat sheet for justfiles. It’s filled with good examples that are short and to the point, probably all from the docs, but anyways I need to do some like this for myself.

Damn this Tim Paul quote finishes hard and such a good point. None of the stuff around llms just work. Good ui’s, front end, back end, infrastructure, product. All these things still need to exist, and in fact for ai to be good we need to still go hard on them otherwise everything will die in a heaping pile of ai slop

I’m no developer, but I got the AI part working in about an hour.

What took longer was the other stuff: identifying the problem, designing and building the UI, setting up the templating, routes and data architecture.

It reminded me that, in order to capitalise on the potential of AI technologies, we need to really invest in the other stuff too, especially data infrastructure.

...

PopSql looks like a very innovative product to bring collaboration to data exploration and visualization in a way you would expect from something like vscode liveshare. This looks far more appealing than a traditional BI data tool.

interesting pricing model from popsql (pronounces Popsicle). At a glance you pay for data retention, want the abiltiy to recall all the queries you ran within the last year, run at a higher frequency, you jump a pricing tier.

such a sick episode with dax.

SST’s free tier will be free as long as aws allows a free tier, their free tier literally costs them nothing.

They talked about keeping SST small, the limitations that brings, but also the number of problems that just go away when you only have 3 people building. Lots of process disappears, everyone can trust everyone, no one needs to wait for approval, everyone is their own PM and just builds cool shit. They don’t have to worry about big costs and making payroll because they are profitable so much higher than their costs.

If they can get through phase one of just being the go platform for a very specific audience of users, and gain marketshare, the ideas of offerings on top of this are endless.

I had no idea that you could just drop an msi installer right in steam. This worked for me, and was much easier to install pokemon tcg live in 05-2024 on ubuntu 22-04. I added the msi to steam from my downloads, hit start, failed right away like he said it would. changed compatability to proton experimental, and it opened right up.

The work on datastar by starfederation.

The hypermedia framework.

exclude=True and repr=False is a good pydantic combination for secret attributes such as user passwords, or hashed passwords. exclude keeps it out of model_dumps, and repr keeps it out of the logs.

just has been by go to tool for saving commands in a way that I can replay them and have team members replay them without relying on the shell history of any given machine. This is my go to default step, it lets you pick a just command to run with a fuzzy picker.

Hatch be flyin.

This new release of hatch includes support for the new package installer uv which is just mind blowing fast compared to anything else we have in python right now.

[tool.hatch.envs.default] installer = "uv"

The other features are cool too, check them out. I’ll probably be using the test runner, but I’ve been waiting for the uv support since uv launched.

I had a boot issue on my sons fresh ubuntu 24.04 install and journalctl came in clutch.

ProblemType: Bug Distr…

This Thread saved my son’s ubuntu 24.04 install. His was failing to start with the following error.

Gdm: GdmSession: no session desktop files installed, aborting...

Super neat tool to convert html to markdown

>>> import html2text >>> >>> print(html2text.html2text("<p><strong>Zed's</strong> dead baby, <em>Zed's</em> dead.</p>")) **Zed's** dead baby, _Zed's_ dead.

It even plays nicely with rich.

Fantastic interview with Uncle Bob, really it was more of a 2 way conversation. So many of Uncle Bob’s takes have been taken out of context, its cool to hear some of the well actuallys, and the experience behind some of the reasoning.

Imagine waking up to a $1,300 for running an example project! That sounds like peanuts for a cloud bill but for an individual trying to learn that hits my monthly budget real hard.

That’s what happened to Marciej, make sure you check out the full article and give them a 👏 on Medium if you have an account.

The more I see things come out about aws, the more it makes me sick, and confirm my feelings that I cannot possibly use them for a side project without some real $$ planning to come out of it.

Yes, S3 charges for unauthorized requests (4xx) as well[1]. That’s expected behavior.

This is a handy reference.

pydantic has a nice built in email validator EmailStr

It requires an optional pydantic dependency

pip install email-validator

Then you can validate email addresses.
