Reposted by Cristian PlanasGergely Orosz @gergely.pragmaticengineer.com · 04/01/2025This is so spot on. Two things: 1. Being focused on producing output the fastest way possible means that you will never prioritize "going deep" 2. Going deep (and down the rabbit hole) is how you learn more: but you need to balance it. Figure out how to do both: it's tricky! 928242

Cristian Planas @cplanas.bsky.social · 14/12/2024Updating my book to Rails 8 (it was written with an example application written in 7) I found an unexpected difference. In Rails 8, the request logs do not show the amount of memory allocations. This was quite useful for the examples of the book. Any way to turn this back on? 132

Reposted by Cristian PlanasGergely Orosz @gergely.pragmaticengineer.com · 02/12/2024There's this evergreen joke on software development that goes something like this: "We're done with 90% of the project. Which means we only have the other 90% left to go." It's funny because it's true. It's also why experienced engineers are in-demand: they are the "finishers." AI tools: not now. 2739948
