TLDR; Colors aren’t values. Yes, as a human you can quickly see what’s up, and that’s great if it’s automatically formatted, I’m all for that. But colorizing a line or cell by hand is possibly the slowest action you can do in a spreadsheet. And yet I see people doing it all the time! Do me a favor, and look at your keyboard. Take one finger and color a cell. Nope, you can’t. There are, however, 26 letters and 10 numbers, right there. No hotkeys, just dedicated buttons, just for those! ...

Assumed Audience Developers — but anyone who picks tools for a living will relate. “No, I don’t use tool X. I do it manually with tool Y, because then I’ll have more grip on what’s happening.” Examples of this are: using git on the command line instead of a GUI using vim instead of an extensive IDE like IntelliJ or VSCode Yes, you’ll understand the lower level part of the problem you’re solving better. But logically this must cost brainpower, otherwise there wouldn’t be more understanding. However, no matter how smart you are, brainpower is a finite resource. ...

TL;DR: gaup.deknijf.com Github Actions is absolutely great. It’s fast, clean, clear, and I’ve yet to encounter a task I can’t accomplish. The main advantage of Github Actions over something like BitBucket Pipelines is the sheer number of modules (called “actions”) that you can just use. Need a docker image built? - name: Set up Docker Buildx uses: docker/setup-buildx-action@v1.6.0 - name: Login to GCR uses: docker/login-action@v1.12.0 with: registry: eu.gcr.io username: _json_key password: ${{ secrets.GOOGLE_SA_KEY }} - name: Build and push run image uses: docker/build-push-action@v2.8.0 with: push: true tags: | eu.gcr.io/<project>/image:${{ github.run_number }} eu.gcr.io/<project>/image:latest cache-from: eu.gcr.io/<project>/image:latest cache-to: type=inline Need some Terraform deployed? ...

Most developers know they should pin their 3rd party dependencies. I usually write Python, but this goes for any language. You don’t want to send your commit into CICD and have it be deployed with packages that are different from what you’ve tested it with locally. On the other hand, every day you lag behind with updating those dependencies you’re making doing that very thing in the future more dangerous. Up to the point that it becomes a “project” in itself, or even until it’s just frozen in place because nobody will touch it. ...

I’d set up a Google App Engine service which was working fine, but I routed traffic to it via an HTTP loadbalancer. Which was working great in acceptance but not so much in production. It just threw a 404: Not Found at me. Nothing else. I checked the service logs, but traffic didn’t seem to arrive at the GEA service. So what now? I enabled the load balancer logs which delivered this gem: ...
