re: Is “Defensive Programming” actually healthy? VIEW POST


This is good (defensive) programming; what differentiates this to a YAGNI issue, is - the time taken to prevent calamity is a lot less than the time needed to fix it later.

If prevention becomes bigger than the actual problem being solved then definitely, YAGNI.

In the spirit of your article, I'm going to say - this is where past, present and future meet in the eternal now, and leave you with this quote:

“To dwell in the here and now does not mean you never think about the past or responsibly plan for the future. The idea is simply not to allow yourself to get lost in regrets about the past or worries about the future. If you are firmly grounded in the present moment, the past can be an object of inquiry, the object of your mindfulness and concentration. You can attain many insights by looking into the past. But you are still grounded in the present moment.”

― Thich Nhat Hanh, The Art of Power


I totally agree about the preventing calamity aspect. It’s hard to straddle the line between future proofing and letting the future rule you. But I think this example is an easy decision due to the low cost and high value.

Btw I’m happy to see another Thich Nhat Hanh fan on dev.to. :) Thank you for your excellent reply. :)
