I got a headache because my WordPress website inaccessible. Discuss with so many forum without any results. The next day I check back to my htaccess file and I found that error is caused by blank enter space on the first line.

I was a fresher. I joined a team, which had build an event driven system. There was an event store ..
Unluckily, all senior devs left the team when i joined.. And event store disk space was increasing at rapid speed and business was behind me to keep the product running.
The ops guys were not willing to give more disk space.

I just deleted the events, and converted the architecture to plain CRUD.

It was bliss at that time. But now that I am experienced I realized, i could have done much better than dropping events table

So probably for me the time I tried an update at 4am, got the wrong branch merged and sent 100 text messages to every user of an app. The app was from a bank. So yeah, I woke 30,000 people up at 4am by having their bank ring them. This incident did make it to Twitter. Ugh. Didn't lose the client BTW and the app continued to be successful. Lucky.

• Merging PRs should be reviewed by ANYONE. I now keep rabbits, a rabbit would do.
• Checklist for "very late at night" deploys including being asked questions by someone, somewhere in the world
• I don't know - learn to live with the shame I guess lol

It was 2015. My first job as a developer. I truncated a production table with no backup thinking I was on my local environment. But lucky for me, the table was small and I could retrieve all the data back by calling 20 customers. Bad day.

Copying so many peoples code and not understanding what I built....or how to use it. Then having to scrap it and start from scratch.

On the bright side I have learned alot about what not to do when starting to code haha

I remember a moment of personal embarrassment that wasn't a huge deal, but early on with DEV, before we had much in the way of PR review or CI I was coding on the site by myself and I recall hearing the Mac "trashcan" sound in my headphones but wasn't sure what it was. I shrugged it off and moved on.

Later, after I'd deployed some code, I noticed that the logo was entirely missing. I'd accidentally put it in the trash somehow and deployed it with git add . without noticing.

It just felt embarrassing because I heard the trash can, and just didn't think much of it. Of course, things are much more careful these days, not that we don't push weird things up.

When i was a fresh grad, I accidentally deleted our client's source code from their production site (They were hosted in cpanel) . A few a minutes after, we already received a complaint from the client. Really thankful that my manager was there to retrieve the backup.

My 2nd job, was working on a mid-range computer at the OS layer. They wanted me to add the ability to save files that had 3 character extensions like .txt, etc. I got it to work, tested it and sent it to distribution folks. 1 week later I found out that I regressed ability to save files without extensions. They had to pull back distribution to 115 countries. Ouch...

i was working with other programmers, and i had a task to implement a new webpage.
It was a big legacy web system made with webforms.
So I based the new implementation in another page already created and deployed. AND for some reason i commented out this entire page...

So when i deployed my new page to prod, I also disabled one of the pages that customers are used to access....

Well, after some boss yelling I fixed it...

And after 1 month i got fired :(

But for good, because of that i am on a very big computer enterprise!!

I once coded in PHP. I know... Was bad...I'm ok now.

Killed a herd of cows with an extra 0.

Biggest "oh my god we're idiots" moment was when me and a colleague (both several years of professional experience at that point) spent almost a full hour debugging, diving into the internals of our frameworks and libraries, trying to figure out why our Typescript class just wouldn't initialise correctly.

Only to realise that we had written "contructor" instead of "constructor"

I initially pushed the initially empty sql database of a recruitment test app for the company to git and then pulled on the server. When the database had received thousands of entries, I made a local change and then force pushed to git and then pulled the empty db on the server. I spent hours panicking and frantically searching on how to undo a force push as recruitment department began messaging me that they couldnt find any entry... luckily for me I had stashed before pulling, even though I didn't know what stash meant and I just did it because of the warning (thank you git deities). That day I immediately learnt not to ever push your db, even if empty... also how to connect postgres and set up automatic back ups

Back in the day, I were the sole active administrator for a private server in world of warcraft. Every wednesday morning, 6:30 am, I was obliged to update the game server with the weeks newest patches and fixes.

One wednesday morning, a morning like the rest of them, I woke up at 6 as usual and had my coffee while I prepared the deployment. The clock ticks and around 6:28 it was time to execute my prepared script on the server which would do everything in "screens" whilst I just supervise it.

Everything went well, green all the way, and off to university I go.

At the lunchbreak, I opened the community forums on my forums in mission to moderate its content while also replying to ingame tickets. I found to my surprise 2 separate forum threads and one ticket implying that "the thing that should be fixed is not fixed, therefore we as 25man guild cannot do this". At once I started looking into it whilst my staff went for damage control.

Only to find out, that the deployment I had done earlier in the morning, was the script for the stage server. Oh what an facepalm, oh so disappointed community members.

My most embarrassing one is likely when I took down our monitoring software when I was co-oping in college. I was building a new site and needed to add it to our monitoring, but I actually just broke the entire thing. I was petrified and didn't know what to do.

When I told me manager, he assured me that wouldn't let me actually configure the production monitoring system - I was after all still just co-op. ) I had been using the stage environment one the whole time. We figured out the problem and got our tools up and running again.

Is it weird to say that I think I do not have an embarrassing story? I have made many mistakes, big and small, and still do. But I don't think any of them are embarrassing. Sure there were mistakes which, in hindsight, were stupid. But I never set out like "hold my beer, and watch this".

When I started I used to do select * from table then filter the data in code.

Probably when I completely forgot how to do headings for an HTML page, until I realized that I had a sticky note literally 5 inches away from my hand. I was stuck for hours, until I realized that im absolute garbage at coding. Fun.
