The Technology We Take for Granted Is Pretty Amazing

We had some intense rapid storms hit last night that caused power failure for roughly 30-40% of Greater Houston area.

Time to test some of my flexible DR developer setup πŸ’ͺ.

I’m sitting the middle row of a nice minivan posting this (thanks Dad for the killer deal! 😁)… and it got me thinking of the “simple” tech we take for granted.

Improve Language Matching in Vscode

Let’s say you have the Red Hat YAML extension. This does a great job with formatting and validation.

However, other directories contain files for Azure DevOps Pipelines that are also yaml. You can tweak the matching logic based on common paths you’d use and get those to default to a different language.

Chunnel, Train, and Pubs

I want to travel by train more. It’s not standard in the US.

Room for my legs, minimal lines & boarding drama.

Easiest Way to Run Local Ai

Ollama makes this really easy. I’ve tried a few options to have local code generation tooling available, and this took the cake for wrapping up localized model running.

I’ve got 64gb of ram on my M2 Max Macbook, so I can just run ollama run llama2:13b and get a local model up and ready to use.

If you are like most of humanity and want less resources taken up, try just ollama run llama2.

St Michel to Versailles

We set off in the car to explore Saint Mont Michel. After a beautiful cruise in the rental at 130kph, we arrived. The parking lot was huge, reminding me of a smaller version of a Six Flag Over Texas. A single bus picked us up and took us to the site. This bus is one of maybe 2 actively in rotation, with a max capacity of 68.

I can’t even imagine how insane this journey would have been during peak season. There’s no way I’d recommend it during a …

Differences in France To My Expectations

Also feels like this isn’t true. While it may be a bit more than the US, which I’d normally greet a small shop owner if we made eye contact, it’s also the same here. Being pleasant goes a long way.

Haven’t seen any case personally where a look was given because of a lack of a greeting, mostly people are busy doing their work and don’t pay you attention.

Parisian Rain, Gluten Free Grains, and Basilica Lanes

Today, I took Karis out for a bit of spontaneity. We decided to go down to Copains, a bakery about 30 minutes away, taking the D train followed by Metro 2. As we walked up the idyllic streets, wet with Paris rain, Copains stood out, bright and cheerful in contrast to the surrounding shops. Its layout was beautiful, reminding me of a minimalist, modern style with plenty of space that could have been used for cafΓ© tables, but was instead just empty. A mosaic-style ceiling …

Potato Chips Taste Better in France

Most of the basic foods lack the same preservatives, food dye, and corn syrup that we commonly have in non-speciality foods in Europe. Lays potato chips at the local market are “natural” and contain far less salt and really taste great.

Lower your expectations with spice though. Last salsa I tried was tomato paste. I asked for the Thai medium spice and it’s like a desert.

They seriously must not like their taste buds to tingle like us Texans.

First Week in Paris

Here’s a bit from the first week. We were pretty exhausted from jet lag so I’ve delayed posting, but figured better something now than to keep on delaying. Enjoy!


Karis’ Entry: We went to a bakery the first full day here in Paris, France. After the bakery, we enjoyed our food at a park. I had a delicious glazed croissant chocolate. Then, as if on cue, a double rainbow appeared. It was amazing - the new double rainbow people! At a bus stop, I caught my first …

Ventilation Systems

Got sucked into reading about ventilation systems in Europe. There’s mechanical and passive based ventilation. I’ve lived most of my adult life where central air systems are used, that it took me a day before I registered the oddity of:

  • no ceiling vents
  • the constant whoosh of air in the bathroom1
  • the seeming airflow from about the full length doors.

While I’m betting this would be a subpar experience in summer compared to what we have in Texas, during less heat induced times …

An Unexpected Supporter of the Paris Sanitation System

Somtimes you feel that you’ve done things right as a parent, even when things go awry. There we were at the park, kids needing a restroom break. Inside, I find no toilet paper, everything broken down, a poor public restroom experience.

Coming out, I see my family on the steps of this Parisian public edifice. I comment on the bathroom’s state.

New York - First Visit

Now that I’ve left New York, here’s what I had started capturing.

Ella: She’s too tired right now to narrate, but there’s a few funny highlights from her day. One of the challenges I gave the kids was to find the first official New York City rat. Ella scored the first point and was very proud of that. She also spent much of the day chasing pigeons and generally being a rascal. Of all the things she noticed, it was stuff like a pair of tennis shoes hanging from a cable …

Leveled Up With Truck Driving

I bought my car, a 2010 Mazdaspeed3, without knowing how to drive a manual tranmission. Thanks to my buddy Jake driving it home, we brought it back. I got a late night crash course in a parking lot, and this saw me through the first month.1

I might have killed the engine a few times2.

So this last week, I drove another stick for the first time. Despite all this time, I realized I’d only driven my Mazdaspeed3. It’s a very touchy and tight sports clutch.

How Many Commits Did You Make in Last Month

Been playing with opencommit and wanted to assess how much using it on every single commit I still could track locally might cost me.

This script loops through all the ${HOME}/git directories and totals the commits made in last month.

Looks like using OpenAI’s api would cost me about $4-$5 if I’d used on every single commit and the size of the commits was smaller.

Not as bad as I’d thought it would be.

Amply Repaid

That’s how children reward you for having them. They are such a responsibility and such a miracle at the same time, that the miracle of the relationship you can have with them amply repays you for the responsibility, if you can only see it. But then you have to go into the depths and take that relationship as a sacred reality and ethical requirement. And you deal with those things casually at your great peril. - Jordan Peterson1

Check Azure Devops Pr for Conventional Commit Title

I’ve used conventional commit most of my career and it’s a fine basic standard, even if sometimes it feels strange as you get used to it. I think it’s far better than inconsistency and is common enough with tooling you can do some nice release, changelog, and versioning with it.

The Pulumi Verdict So Far

My Job

Pulumi Round 2

This is not a comprehensive article, but more a log of the issues and wins as I work through Pulumi adoption.

  • Pulumi is pretty powerful.
  • Once you get beyond the basics, it requires a lot of effort since the tooling doesn’t have as many examples as I’d hope. This is especially true for Kubernetes. It’s a lot easier to get moving on other providers.
  • It’s more intensive of a pilot to do complex things IMO than Terraform, because you aren’t getting pre-built …

Docker Healthchecks for Spinning Up Local Stacks

Thermal Throttling Mac Intel Woes

I lost roughly half a day in productivity. CPU hit 100% for an extended period, making it difficult to even use the terminal.

My Goland Log

This is a log of my second journey in using Goland from Jetbrains for Go development.

I’ve got VSCode in a great state. It’s flexible, powerful, and I’ve highly customized it to my workflow.

However, doing Go development, I’d like to better explore Jetbrains Goland and see if the experience proves positive.

I’ll log updates and issues here as I work through it in the hope that it might provide you better information if you are considering Goland as well. …

Steampipe Is Sql Magic

I tried Steampipe out for the first time today.

Follow Steampipe On Twitter

I’m seriously impressed.

I built a project go-aws-ami-metrics last year to test out some Go that would iterate through instances and AMIs to build out aging information on the instances.

I used it to help me work through how to use the AWS SDK to iterate through regions, instances, images, and more.

My First Vscode Extension Pack for Go

Took a swing at creating my own extension pack for Go.

sheldonhull/extension-pack-go - GitHub

This was a good chance to familarize myself with the eco-system and simplify sharing a preset group of extensions.

Setup the repo with a Taskfile.yml to simplify running in the future. If frequent updates needed to happen, it would be easy to plug this into GitHub actions with a dispatch event and run on demand or per …

Simplify Aws Developer Security With Leapp
