Time for the last Weekly Digest in March! Today I have six juicy links and you can read a HashiCorp banking story, saving money by NOT going into the cloud, adding a screen to the laptop using Raspberry Pi, a nice story about a bug found during working on Crash Bandicoot and more!

Business and (side)project section

3. Herding elephants: Lessons learned from sharding Postgres at Notion


You have probably heard of or even use Notion as it is pretty popular and has many users nowadays. But have you heard, as a developer, how they make the app work smoothly? They have sharded Postgres, which is not as common as it sees, and they are sharing their lessons learned!

4. Using a Raspberry Pi to add a second HDMI port to a laptop

5. 20 Things I’ve Learned in my 20 Years as a Software Engineer


Fellow developer shares his lesson learned after working 20 years as a Software Engineer. For example, as a programmer, you may tend to instantly go into writing code, but as number 4 points out - the best code is the code that has not been written! It is good to read a succh summary sometimes!

6. My Hardest Bug Ever


This story is about a bug - from one of the developers working on the Crash Bandicoot. The author calls it the hardest bug ever as it occurs on a very specific occasion (when the user saves data AND wiggles the controller) and in the end it was a hardware bug - cross-talk between circuits on the console motherboard.
