The riskiest dev choice...
How about "The riskiest thing you've done as a dev"? I have a great entry for that. and I suppose it was my choice to build the feature afterall.
I was working on an instance of a small MMO at a game company I worked for. The MMO boasted multiple servers, each of them a vastly different take on the base game. We could use, extend, or outright replace anything we wanted to, leading to everything from Zelda to pokemon to an RP haven to a top-down futuristic counterstrike. The server in this particular instance was a fantasy RPG, and I was building it a new leveling and experience system with most of the trimmings. (Talents, feats/perks, etc. were in a future update.)
A bit of background, first: the game's dev setup did not have the now-standard dev/staging/prod servers; everything ran on prod, devs worked on prod, players connected and played on prod, etc. Worse yet, there was no backup system implemented -- or not really. The CTO was really the only person with sufficient access. The techy CEO did as well, but he rarely dealt with anything technical except server hardware, occasionally. And usually just to troll/punish us devs (as in "Oops ! I pulled the cat5 ! ;)"). Neither of them were the most reliable of people, either. The CTO would occasionally remote in and make backups of each server -- we assumed whenever he happened to think of it -- and would also occasionally do it when asked, but it could take him a week, sometimes even up to a month to get around to it. So the backups were only really useful for retreiving lost code and assets, not so much for player data.
The lack of reliable backups and the lack of proper testing grounds (among the plethora of other issues at the company) made for an absolutely terrible dev setup, but that's just how it was, and that's what we dealt with. We were game devs, afterall. Terrible or not, we got to make games! What more could you ask for!? It was amazing and terrible and wonderful and the worst thing ever, all at the same time. (and no, I'm not sharing the company name, but it isn't EA or Nexon, surprisingly 😅)
Anyway, back to the story! My new leveling system also needed to migrate players' existing data, so... you can see where this is going.
I did as much testing and inspection of my code as I could, copied it from a personal dev script to the server's xp system, ... and debated if I really wanted to click [Apply]. Every time I considered it, I went back to check another part or do yet more testing. I ended up taking like 40 minutes to finally click it.
And when I did... that was the scariest button press of my life. And the scariest three seconds' wait afterwards. That one click could have ruined every single player's account, permanently lost us players ...
After applying it, I immediately checked my character to see if she was broken, checked the account data for corruption or botched flags, checked for broken interactions with the other systems....
Everything ended up working out perfectly, and the players loved all of the new features. They had no idea what went into building them, and certainly had no idea of what went into applying them, or what could have gone wrong -- which is probably a good thing.
Looking back, that entire environment was so fragile, it's a wonder things didn't go horribly wrong all the time. Really, they almost never did. Apocalypses did happen, but were exceedingly rare, and were ususally fixed quickly. I guess we were all super careful simply because everything was so fragile? or the decent devs were, at least. We never trusted the lessers with access 😅 at least on the main servers where it mattered. Some of the smaller servers... well, we never really cared about those.
But I'm honestly more surprised to realize I've never had nightmares of that button click. It was certainly terrifying enough.
But yay! Complete system overhaul and migration of stored and realtime player data! on prod! With no issues! And lots of happy players! Woooooo!
Thinking back on it makes me happy 😊rant deploying straight to prod prod prod prod dev server? dev on prod you chicken migration on prod wk149 git? who's a git? you're a git! scariest deploy ever game development1 -
A young guy I work with burst into tears today, I had no idea what happened so I tried to comfort him and ask what was up.
It appears his main client had gone nuts with him because they wanted him to make an internet toolbar (think Ask.com) and he politely informed them toolbars doesn't really exist anymore and it wouldn't work on things like modern browsers or mobile devices.
Being given a polite but honest opinion was obviously something the client wasn't used to and knowing the guy was a young and fairly inexperienced, they started throwing very personal insults and asking him exactly what he knows about things (a lot more than them).
So being the big, bold, handsome senior developer I am, I immediately phoned the client back and told them to either come speak to me face-to-face and apologise to him in person or we'd terminate there contract with immediate effect. They're coming down tomorrow...
So part my rant, part a rant on behalf of a young developer who did nothing wrong and was treated like shit, I think we've all been there.
We'll see how this goes! Who the hell wants a toolbar anyway?!401 -
Ran into a girl who I had a crush on in high school at a bar last week. Hanged out for a bit, but then I had to run catch the last train home.
Today I get a message from her that reads: "Hey, it was nice to meet you last week. Can I call you some time, there's something I want to tell you. 😉"
I think to myself -- sweet and say that I have no meetings today, call me whenever you can.
A couple of minutes later she calls me, and the first thing she says: "I have this app idea..."
fuck, shouldn't have hyped myself up.29 -
On Monday the boss says this needs to be done by Wednesday.
I get it done and mid Wednesday I tell my teammates, it's done, and I've done my 40 hours this week. See you next week. Bye!1 -

MOTHER OF ALL AUTOMATIONS
This seems a long post. but you will definitely +1 the post after reading this.
xxx: OK, so, our build engineer has left for another company. The dude was literally living inside the terminal. You know, that type of a guy who loves Vim, creates diagrams in Dot and writes wiki-posts in Markdown... If something - anything - requires more than 90 seconds of his time, he writes a script to automate that.
xxx: So we're sitting here, looking through his, uhm, "legacy"
xxx: You're gonna love this
xxx: smack-my-bitch-up.sh - sends a text message "late at work" to his wife (apparently). Automatically picks reasons from an array of strings, randomly. Runs inside a cron-job. The job fires if there are active SSH-sessions on the server after 9pm with his login.
xxx: kumar-asshole.sh - scans the inbox for emails from "Kumar" (a DBA at our clients). Looks for keywords like "help", "trouble", "sorry" etc. If keywords are found - the script SSHes into the clients server and rolls back the staging database to the latest backup. Then sends a reply "no worries mate, be careful next time".
xxx: hangover.sh - another cron-job that is set to specific dates. Sends automated emails like "not feeling well/gonna work from home" etc. Adds a random "reason" from another predefined array of strings. Fires if there are no interactive sessions on the server at 8:45am.
xxx: (and the oscar goes to) fuckingcoffee.sh - this one waits exactly 17 seconds (!), then opens an SSH session to our coffee-machine (we had no frikin idea the coffee machine is on the network, runs linux and has SSHD up and running) and sends some weird gibberish to it. Looks binary. Turns out this thing starts brewing a mid-sized half-caf latte and waits another 24 (!) seconds before pouring it into a cup. The timing is exactly how long it takes to walk to the machine from the dudes desk.
xxx: holy sh*t I'm keeping those

Me: so, ifconfig, what is my gateway?
ifconfig: [ip address]
Me: nmap, what is this IP address?
nmap: it's a network switch with an open telnet port.
Me: what happens if I connect to it?
switch: WHAT IS THE PASSWORD?!?!
Me: is it blank?
switch: correct. what do you want to do?
Me: can I look at all the IP and MAC addresses on the network?
switch: WHAT IS THE ADMIN PASSWORD?!?!
Me: is it... admin?
switch: correct. Here's everyone that's connected to the network: [400+ IPs and MACs]
Me: ok python, would you filter through these and tell me what manufacturer each one belongs to?
python: sure.
[~50 manufacturer lookups later]
python: there's a bunch of apple product, a bunch of miscellaneous laptop and printer manufacturers, and some raspberry pis.
Me: raspberry pis?
python: yep. about 20 of them.
Me: What happens if I connect to one?
rpi: WHAT IS THE PASSWORD?!?!
Me: raspberry?
rpi: correct. what do you want to do?
Me: can I make you do my bidding in the background when you aren't being used?
rpi: sure, sounds fine.
I love ignorant sysadmins.8 -
Difference between C# and Javascript
Me: Hold my cup of tea.
C#: That's not a cup of tea.
Me: Hold my cup of tea, with two teaspoons of sugar in it.
C#: That's not a cup of tea with two tea spoons of sugar in it.
Me: Hold my cup of tea, with two teaspoons of sugar and milk in it.
C#: That is not a cup of tea, with two teaspoons of sugar and milk it.

Me: Hold my cup of tea.
Javascript: I'll hold your cup of coffee.31 -
It was between me and another guy.

I don't understand why so many people fight this war of tabs vs spaces. My colleagues elegantly solved the problem just not using indentation at all36

I hired a woman for senior quality assurance two weeks ago. Impressive resume, great interview, but I was met with some pseudo-sexist puzzled looks in the dev team.
Meeting today. Boss: "Why is the database cluster not working properly?"
Team devs: "We've tried diagnosing the problem, but we can't really find it. It keeps being under high load."
New QA: "It might have something to do with the way you developers write queries".
She pulls up a bunch of code examples with dozens of joins and orderings on unindexed columns, explains that you shouldn't call queries from within looping constructs, that it's smart to limit the data with constraints and aggregations, hints at where to actually place indexes, how not to drag the whole DB to the frontend and process it in VueJS, etc...
New QA: "I've already put the tasks for refactoring the queries in Asana"
I'm grinning, because finally... finally I'm not alone in my crusade anymore.
Boss: "Yeah but that's just that code quality nonsense Bittersweet always keeps nagging about. Why is the database not working? Can't we just add more thingies to the cluster? That would be easier than rewriting the code, right?"
Dev team: "Yes... yes. We could try a few more of these aws rds db.m4.10xlarge thingies. That will solve it."
QA looks pissed off, stands up: "No. These queries... they touch the database in so many places, and so violently, that it has to go to therapy. That's why it's down. It just can't take the abuse anymore. You could add more little brothers and sisters to the equation, but damn that would be cruel right? Not to mention that therapy isn't exactly cheap!"
Dev team looks annoyed at me. My boss looks even more annoyed at me. "You hired this one?"
I keep grinning, and I nod.

Me: 1 is something, 0 is nothing, NULL is the absence of things
JuniorDev: wut
Me: You've got pizza in a box, that's 1. If there's no pizza in the box, that's 0. If there's no pizza and no box, that's NULL.
JuniorDev: OOH so there's no object to reference if I ask for a slice!
Me: *small tear*
Always explain things in terms of pizza. Always.25 -

After over 20 years as a Software Engineer, Architect, and Manager, I want to pass along some unsolicited advice to junior developers either because I grew through it, or I've had to deal with developers who behaved poorly:
1) Your ego will hurt you FAR more than your junior coding skills. Nobody expects you to be the best early in your career, so don't act like you are.
2) Working independently is a must. It's okay to ask questions, but ask sparingly. Remember, mid and senior level guys need to focus just as much as you do, so before interrupting them, exhaust your resources (Google, Stack Overflow, books, etc..)
3) Working code != good code. You are an author. Write your code so that it can be read. Accept criticism that may seem trivial such as renaming a variable or method. If someone is suggesting it, it's because they didn't know what it did without further investigation.
4) Ask for peer reviews and LISTEN to the critique. Even after 20+ years, I send my code to more junior developers and often get good corrections sent back. (remember the ego thing from tip #1?) Even if they have no critiques for me, sometimes they will see a technique I used and learn from that. Peer reviews are win-win-win.
5) When in doubt, do NOT BS your way out. Refer to someone who knows, or offer to get back to them. Often times, persons other than engineers will take what you said as gospel. If that later turns out to be wrong, a bunch of people will have to get involved to clean up the expectations.
6) Slow down in order to speed up. Always start a task by thinking about the very high level use cases, then slowly work through your logic to achieve that. Rushing to complete, even for senior engineers, usually means less-than-ideal code that somebody will have to maintain.
7) Write documentation, always! Even if your company doesn't take documentation seriously, other engineers will remember how well documented your code is, and they will appreciate you for it/think of you next time that sweet job opens up.
8) Good code is important, but good impressions are better. I have code that is the most embarrassing crap ever still in production to this day. People don't think of me as "that shitty developer who wrote that ugly ass code that one time a decade ago," They think of me as "that developer who was fun to work with and busted his ass." Because of that, I've never been unemployed for more than a day. It's critical to have a good network and good references.
9) Don't shy away from the unknown. It's easy to hope somebody else picks up that task that you don't understand, but you wont learn it if they do. The daunting, unknown tasks are the most rewarding to complete (and trust me, other devs will notice.)
10) Learning is up to you. I can't tell you the number of engineers I passed on hiring because their answer to what they know about PHP7 was: "Nothing. I haven't learned it yet because my current company is still using PHP5." This is YOUR craft. It's not up to your employer to keep you relevant in the job market, it's up to YOU. You don't always need to be a pro at the latest and greatest, but at least read the changelog. Stay abreast of current technology, security threats, etc...
These are just a few quick tips from my experience. Others may chime in with theirs, and some may dispute mine. I wish you all fruitful careers!221
