What it's like to be a network engineer...translated into normal people speak
User: I think we are having a major road issue.
Me: What? No, I just checked, the roads are fine. I was actually just on the roads.
User: No, I’m pretty sure the roads are down because I’m not getting pizzas.
Me: Everything else on the roads is fine. What do you mean you aren’t getting pizzas?
User: I used to get pizzas when I ordered them, now I’m not getting them. It has to be a road issue.
Me: As I said, the roads are fine. Where are you getting pizzas from?
User: I’m not really sure. Can you check all places that deliver pizzas?
Me: No I don’t even know all the places that deliver pizza. You need to narrow it down.
User: I think it is Subway.
Me: Okay, I’ll check…No, I just looked and Subway doesn't deliver pizzas.
User: I’m pretty sure it is Subway. Can you just allow all food from Subway and we can see if pizza shows up?
Me: Sigh, fine I’ve allowed all food from Subway, but I don’t think that is the issue.
User: Yeah I’m still not getting pizza. Can you check the roads?
Me: It’s not the roads, the roads are fine. I’m pretty sure Subway isn’t the place.
User: Okay, I found it. It’s Papa Johns.
Me: Okay, I looked and Papa Johns does deliver pizza. Is it the local Papa Johns or one in a different town?
User: I don’t know. Can you allow pizza from all Papa Johns to me?
Me: No I can’t do that. Can you get me an address for Papa Johns?
User: No, I only know it as Papa Johns. Can you get me all the addresses of all Papa Johns and I’ll tell you if one of them is correct?
Me: No, I don’t have time for that. Okay, I looked at the local one and it looks like they have sent you pizza in the past and they are currently allowed to send you pizzas. Try ordering a pizza while I watch.
User: Yeah still no pizza. I’m guessing they are getting blocked at the freeway. Can you check the freeway to make sure they can get through?
Me: No, this is a local delivery. They aren't even using the freeway.
User: Okay, well then it has to be a road issue.
Me: No, the roads are fine. Okay, I just drove from the Papa Johns to the address they have on file for you and there is nothing there.
User: Hmm, wait we did move recently.
Me: Did you give your new address to Papa Johns?
User: No, I just thought they would be able to look me up by name.
Me: No they need your new address. What’s your new address?
User: I’m not really sure. Can you look it up?
Me: Sigh, give me a second…Okay, I found your address and gave it to Papa Johns. Try ordering a pizza now.
User: HEY! PIZZA JUST SHOWED UP!
Me: Okay, good.
User: (To everyone else they know) I apologize for the delay in the pizza but there was a major road issue that was preventing the pizza from getting to me. The network engineer has fixed the roads and we are able to get pizza again.
Me: But it wasn’t the roads…whatever.
User: Oh, can you also check on an issue where Chinese food isn’t getting to me? I think it may be a road issue49 -
My best code review experience?
Company hired a new department manager and one of his duties was to get familiar with the code base, so he started rounds of code reviews.
We had our own coding standards (naming, indentation, etc..etc) and for the most part, all of our code would pass those standards 100%.
One review of my code was particularly brutal. I though it was perfect. In-line documentation, indentation, followed naming standards..everything. 'Tom' kept wanting to know the 'Why?'
Tom: 'This method where it validates the amount must be under 30. Why 30? Why is it hard-coded and not a parameter?'
<skip what it seemed like 50 more 'Why...?' questions>
Me: "I don't remember. I wrote that 2 years ago."
Tom: "I don't care if you wrote it yesterday. I have pages of code I want you to verify the values and answer 'Why?' to all of them. Look at this one..."
'Tom' was a bit of a hard-ass, but wow, did I learn A LOT. Coding standards are nice, but he explained understanding the 'What' is what we are paid for. Coders can do the "What" in their sleep. Good developers can read and understand code regardless of a coding standard and the mediocre developers use standards as a crutch (or worse, used as a weapon against others). Great developers understand the 'Why?'.
Now I ask 'Why?' a lot. Gotten my fair share of "I'm gonna punch you in the face" looks during a code review, but being able to answer the 'Why?' solidifies the team with the goals of the project.3
