# Tenets of IT
|
||||
*It is a good reminder to not overthink some problems. These tenets have been created over decades as a way of reminding ourselves of the things sometimes overlooked.*
|
||||
|
||||
1. Reboot, reinstall, replace.
|
||||
2. Rebooting is a band aid. Figure out why you had to.
|
||||
3. It's always DNS
|
||||
4. When it’s not DNS, it’s MTU.
|
||||
5. When it’s not MTU, it’s BGP.
|
||||
6. When it’s not BGP, it’s LACP.
|
||||
7. Under-promise, over-deliver
|
||||
8. Plan for the worst, hope for the best.
|
||||
9. Always implement two-factor-authentication, no matter how loudly the users complain.
|
||||
10. Have the user show you the problem, often it is the user doing something in an unusual way.
|
||||
11. Fast. Cheap. Good. You may pick one, two if you're lucky.
|
||||
12. Never stop learning.
|
||||
13. The Six Ps: Proper Planning Prevents Piss Poor Performance
|
||||
14. It's always an emergency, until it incurs an extra charge
|
||||
15. Everyone has a test environment, not everyone is lucky enough to have a separate production environment.
|
||||
16. If anyone can't find the documentation it's not documented, if it's not documented it doesn't exist.
|
||||
17. If you think it's going to be a disaster, get it in writing and CYA
|
||||
18. Poor planning on a users part, does not constitute an emergency on yours
|
||||
19. Fridays are read-only (aka - no changes on a Friday)
|
||||
20. A backup isn't a backup until you've restored successfully from it.
|
||||
21. Snapshots are not backups
|
||||
22. If a backup isn't off-site, it isn't a backup.
|
||||
23. If it isn't in a ticket, it's not getting done.
|
||||
24. Treat all users the same, regardless of their last name.
|
||||
25. It's never a "5 minute thing".
|
||||
26. Security and ease of use.. rarely walk hand in hand.
|
||||
27. Not my circus, not my monkeys.
|
||||
28. Everybody lies.
|
||||
29. Never ask a user a question that you can easily confirm yourself.
|
||||
30. The fastest path to resolution first requires removing the user from the problem. (aka isolate layer 8)
|
||||
31. You are replaceable at work, no matter how highly you think of yourself. You are not replaceable at home.
|
||||
32. Never give a web developer/designer access to the DNS.
|
||||
33. Own up to your mistakes. That way, when it isn’t your fault, people will believe you.
|
||||
34. If you have to do something twice, automate it.
|
||||
35. Never spend 6 minutes doing something manually, that you spend 6 hours failing to automate.
|
||||
36. To make an error is human. To propagate an error to all servers in an automatic way is devops.
|
||||
37. Skilled IT professionals will continuously be given more work, until they can do none of it skillfully.
|
||||
38. Give me a new hire that is a blank slate and willing to learn, over a seasoned tech that hates this job and doesn't want to learn or change.
|
||||
39. IT time is relative.
|
||||
40. Yes it's free/cheap. No, it's not going in the server room.
|
||||
41. You provide the problem and business case, let IT provide the solution.
|
||||
42. IT's job is to solve people problems with technology.
|
||||
43. Technology can't solve people problems.
|
||||
44. Nothing is more permanent than a temporary expedient.
|
||||
45. Fix the problem now, it's just going to happen again when it's less convenient.
|
||||
46. If the network guys say it's not the network, there is an 80% chance it's the network.
|
||||
47. Traceroute is your friend.
|
||||
48. 80% of the time CAPEX becomes OPEX when you can get 0% financing. Accounting HATES CAPEX.
|
||||
49. If it doesn't log automatically make it log! Log's just spit out the answer for you!
|
||||
50. There are some jobs and clients you must walk away from.
|
||||
51. If you can smell the magic smoke, you’re already screwed.
|
||||
52. "Working just fine" and "too screwed to log an error" look an awful lot alike.
|
||||
53. The longer everything goes according to plan, the bigger the impending disaster.
|
||||
54. Sales Engineers are a gift from heaven, they prevent salespeople from over-promising.
|
||||
55. Printers have moods, most of the time that mood is 'Fuck you'.
