[1136.78 --> 1138.56] It's possible for a few people to break glass. |
[1138.66 --> 1142.86] They could do so in about five minutes once we actually understood what we actually had to do. |
[1143.30 --> 1147.00] It took about 20 minutes for us to gain any visibility and sort of understand, |
[1147.54 --> 1149.12] hey, it's this feature. |
[1149.34 --> 1150.12] Go turn that off. |
[1150.56 --> 1151.66] Regular expressions, huh? |
[1151.66 --> 1152.90] They're still hard. |
[1153.22 --> 1154.06] They're hard for everyone. |
[1155.20 --> 1156.04] Easy to write. |
[1156.20 --> 1157.32] Hard to understand what they're doing. |
[1157.50 --> 1158.58] Why are they called that? |
[1158.76 --> 1160.90] Because what is regular about them? |
[1161.58 --> 1162.70] That's out of my domain. |
[1162.90 --> 1164.54] I don't know if anyone's got the answer for that. |
[1165.06 --> 1165.90] No, genuinely have. |
[1166.36 --> 1170.12] I just watched a talk from Strangeloop about regular expressions. |
[1170.84 --> 1172.68] And the speaker did go into this. |
[1172.70 --> 1175.10] And I've completely forgotten what she said. |
[1175.40 --> 1177.66] But we can probably put that talk in the show notes. |
[1177.66 --> 1180.22] It was a really good one about just the history. |
[1180.46 --> 1182.26] Ken Thompson came up, which is pretty cool. |
[1182.42 --> 1183.60] I'm like, oh, I know that dude. |
[1184.52 --> 1184.70] Yeah. |
[1184.78 --> 1189.34] But no, it has to do with mathy things and finite automata and all of that. |
[1190.18 --> 1190.34] Yeah. |
[1190.34 --> 1196.98] When I was a junior, which is the closest to intern I was, I was working with a team lead. |
[1197.20 --> 1199.62] And when we deployed something together, we looked at it. |
[1200.08 --> 1201.88] And I forget what it was exactly. |
[1201.98 --> 1209.46] But this is a company that receives a lot of pings from the SDK of the many clients. |
[1209.46 --> 1210.52] And it's all real time. |
[1210.52 --> 1216.74] And if that is not logged, then the entire transaction, like flow, user flow is gone forever. |
[1217.78 --> 1220.66] And we deployed something we worked on together. |
[1220.80 --> 1222.00] We worked on it for half a day. |
[1222.10 --> 1222.80] We tested it. |
[1222.86 --> 1225.66] We did all the good practices because that's how you do with a junior, right? |
[1225.72 --> 1227.12] You want to show that you're very thorough. |
[1227.26 --> 1233.92] You go for all the tests, deploy, look at all the metrics and see that it behaves as expected. |
[1234.54 --> 1236.50] And then he went to lunch and then I stayed. |
[1236.94 --> 1237.78] Da-da-da. |
[1237.78 --> 1238.78] Da-da-da. |
[1239.82 --> 1242.34] And then I proceeded to do something else. |
[1242.38 --> 1246.58] And then suddenly a weird behavior started pinging Slack, all the monitoring channels. |
[1246.74 --> 1247.36] It's like something wrong. |
[1247.44 --> 1247.94] Something's weird. |
[1248.44 --> 1254.20] And then some of the colleagues that were there tried to see where it comes from. |
[1254.90 --> 1257.80] And we couldn't figure this out in 15 minutes. |
[1257.80 --> 1263.40] And then bravely came to the head of the DevOps team. |
[1263.54 --> 1265.60] There was no SRE team at the time. |
[1265.60 --> 1267.80] And I said, I think it's this thing that we did. |
[1267.90 --> 1268.76] Can I revert it? |
[1269.18 --> 1275.08] Nobody else, from all the other senior people that don't have another better word than brave, |
[1275.14 --> 1276.20] but I don't want to use the word brave. |
[1276.52 --> 1280.44] Nobody else wanted to do anything about that because nobody was sure. |
[1280.54 --> 1282.44] And then I was like, let's do this. |
[1282.52 --> 1283.46] Let's try it worse. |
[1283.68 --> 1285.34] It cannot get much worse than that, right? |
[1285.50 --> 1287.38] And reverting that indeed succeeded. |
[1287.54 --> 1288.66] And then we were all very happy. |
[1288.66 --> 1290.42] And then I was like, I think I know how to fix it. |
[1290.48 --> 1290.94] Can I try? |
[1291.04 --> 1292.54] And then he looked at me and said, no. |
[1293.66 --> 1294.44] Stay away. |
[1297.36 --> 1299.10] I went to the next level of brave. |
[1299.44 --> 1299.76] Yeah. |
[1300.02 --> 1302.54] Well, what a great way to learn stuff though, isn't it? |
[1303.66 --> 1304.20] Break them. |
[1304.42 --> 1304.54] Yeah. |
[1305.20 --> 1308.32] How often does that memory come back to haunt you, Natalie? |
[1309.14 --> 1310.62] Every time I'm asked to please. |
[1311.02 --> 1311.24] Yeah. |
[1312.36 --> 1315.16] Every time I get to speak with other junior people. |
[1315.16 --> 1318.06] So to give the good example of it, obviously you will break something. |
[1318.42 --> 1320.90] So be reasonable about your expectations. |
[1322.52 --> 1322.88] Nice. |
[1323.06 --> 1327.18] I'm curious if you have a way, like now that you're older and wiser and, you know, |
[1327.20 --> 1329.08] you've been through the experience, which is a great teacher. |
[1329.44 --> 1334.72] I'm wondering, do you have strategies now for doing things that are scary, |
[1334.90 --> 1335.92] that could break things? |
[1335.92 --> 1337.94] Like, do you have a strategy for tackling that now? |
[1338.34 --> 1341.00] The thing is we did everything right at the time, right? |
[1341.00 --> 1343.66] So we did all the tests we could think of. |
[1343.66 --> 1348.86] We thought, what do we expect in the logs and the monitoring and the dashboard? |
[1349.26 --> 1350.02] And we observed. |
[1350.62 --> 1353.36] So the only thing that I would do different is not to plot it for lunch. |
[1356.42 --> 1358.58] So you can, I guess, observe for longer. |
[1359.56 --> 1360.94] Speaking of spooky things, right? |
[1361.16 --> 1362.22] What are we having for lunch? |
[1362.96 --> 1363.18] Yeah. |
[1363.18 --> 1364.46] I don't think I had lunch that day. |
[1364.96 --> 1368.12] I mean, I was like gnashing stuff, but I don't think I had a lunch lunch. |
[1368.30 --> 1368.48] Yeah. |
[1368.50 --> 1370.98] There's another theme emerging here. |
[1370.98 --> 1375.54] One of the main reasons to write good code is so you can just have lunch. |
[1376.56 --> 1377.48] Quite a good reason. |
[1377.78 --> 1379.00] That's another thing I would do different. |
[1379.14 --> 1379.90] I would write good code. |
[1380.18 --> 1380.28] Yeah. |
[1382.16 --> 1382.84] That's optional. |
[1383.20 --> 1385.02] If you've got good tests, you don't need good code. |
[1386.36 --> 1386.72] Controversial. |
