SaturdayMP Show 100: PostCast Part 15 (LinkedIn Company Setup)

Posted on May 26, 2026 by Chris C

Our 100th episode! Not the episode we wanted as we forgot we needed to register with @linkedin to post messages as a company and then struggle to figure out how to handle multiple dialog forms in Fyne.

That said, a janky 100th episode fits with the theme of the SaturdayMP Show where we show our struggles and warts beside our successes.

Thank you to YouTube for letting me post these long videos for free. I know they make money of ads and other data, but it’s still nice of them.

Thanks to Omar for joining me for the past couple months. I really enjoy having someone be banter with, ask questions, and suggest things I never would have thought of or tried, such as doing live streams.

A big THANK YOU to those mighty few that have watched the videos. I make these videos because they let me play and learn outside of a client work, but it makes me smile that others find them useful and/or entertaining.

SaturdayMP Show 99: Custom Ping Client – Part 2

In this live episode Omar and myself get the ping application working. Not the best written C code, but it works, after I figured out we need to run the application as root.

SaturdayMP Show #98: Custom Ping Client

Posted on May 12, 2026 by Chris C

In this live episode Omar and myself try to write a low-level C app that does a network ping. Omar really wanted the app to be in C, so you get to watch me struggle to remember C syntax and translate bytes, chars, etc.

We do an OK job of explaining networking but a better job of explaining hex and how numbers are represented by bits (base 2) and bit shifting.

SaturdayMP Show #97: PostCast Part 14 (Slack Integration Working)

Posted on May 12, 2026 by Chris C

Happy Star Wars Day! In this live episode Omar and myself get the Slack integration working. At least a ruff draft of it that still needs some clean-up. We also discuss the lower level networking details like ports and sockets.

SaturdayMP Show 96: PostCast Part 13 (Save Slack Token Using TDD)

Posted on May 12, 2026 by Chris C

In this live episode Omar and myself write and unit test the code for saving the Slack token to the keyring. We abandon using Testify mocks and instead add an in-memory setting for our credential manager. We also have a good discussion about test-driven development (TDD).

SaturdayMP Show #94: Debugging Git HTTP 400 curl 22 Error

Posted on April 22, 2026 by Chris C

In our first ever completely live episode, Omar and myself debug a GitHub push error Omar was experiencing. It was a new error for both of us and took a bit to figure out. The error was:

error: RPC failed; HTTP 400 curl 22 The requested URL returned error: 400

The tl;dw (to-long;didn’t-watch) is the image was larger than the Git post buffer size. The fix was to compress the image, which is something we are doing for the Weekly Dev Chat website. Another fix is to increase the Git post buffer size.

SaturdayMP Show 93: PostCast (Part 12 – Start on Slack API)

Posted on April 15, 2026 by Chris C

In this episode Omar and myself start working on the Slack integration for PostCast. We start off by reviewing what we have learned about the Slack API so far. Then we come up with a plan of attack and start implementing the plan but don’t get very far.

We struggle to remember how mocking works in Go and then run out of time as I needed to host the Weekly Dev Chat. I’m likely overthinking the mocking and am too used to other languages/technologiges where mocking is easier and more common.

SaturdayMP Show 91: PostCast (Part 11 – Saving LinkedIn Token)

Posted on April 1, 2026 by Chris C

In this PostCast episode Omar and myself figure out how to save the LinkedIn API token. Previously we saved the LinkedIn API ClientID and ClientSecret, which we knew was incorrect, but we just wanted to get something working. Now we correctly save the token, which is what should be saved.
