Maxims of Maximally Effective Startup Developer

1. Test, then Deploy
2. A coding Developer outranks an Architect who doesn't know what's going on
3. If the food is good enough, the devs will stop complaining about the incoming workload
4. Only you can prevent prod failure. 
5. If testing wasn’t your last resort, you failed to resort to enough of it.
6. The longer everything goes according to sprint planning, the bigger the impending disaster. 
7. The world is richer when you turn competitors into partners, but that's not the same as you being richer.
8. Give a developer a task, he will code for a day. Take his software away and tell him he's lucky just to be paid, and he'll figure out how to code another one for you to take tomorrow. 
9. "Deploy and Forget" is fine, provided you never actually forget.
10. Don't be afraid to be the first to resort to rollback.
11. The competitor of my competitor is my competitor's competitor. No more. No less.
12. There is no over testing.' There is only 'Continuous Integration' and 'I need to spawn more Jenkins slave'
13. Just because a feature is easy for you, it can still be hard to your clients.
14. There is a difference between a spare feature and extra [feature].
15. Not all good news is competitor action. 
16. “Do you have a backup?” means “I can’t fix this.” 
17. The size of a developer startup stock options is inversely proportional to the likelihood of the startup surviving to collect it
18. Don’t try to save money by conserving lines of code.
19. Don't expect the competition to cooperate in the creation of your dream startup
20. If it ain't broke, it hasn't been deployed to prod yet.
21. The dev team you've got is never the dev team you want.
22. The product management guideline you've got is never the guideline you want
23. The best way to win a one-on-one architecture design is to be the third to arrive.
24. It's only too many features if only the devs use them
25. Don't bring big VMs into small servers
26. Management knows how to do it by knowing who can code it 
27. Failure is not an option - it is mandatory. The option is whether or not to let failure be the last thing you test.
