Usually this only includes some of the cli tools preinstalled on e.g. ubuntu-server, stuff like rm, mv, rsync, dd and so on. We try to use IAC so working on the server is kind of rare anyways. So we ask people to maintain using only commands on the list(that we aliased, to add that extra sanity check) and if they want to use another tool they can just expand the list and add the alias. Made more sense than going out and aliasing literally everything...

Sometimes they had to open a transaction, do their data entry, check that the result was as expected, and then commit the transaction. If they forgot the commit, the transaction could be open for a long time, and if there was a hiccup in the database connection, the transaction and their changes would be lost. To remind them to close the transaction I had the background of the form, which was normally just grey, turn a bright colored stripe so you could tell at a glance that a transaction was open.

Also, preventing rm -rf with something like an alias to run a command that wraps rm -rf in prod so an alert, prompt or ANYTHING is shown that you are in prod, and have to confirm your command by WRITING "confirm" This just sounds like every other company that trust too much in their humans, which are the most risky component of a system

I get flack sometimes when I force a person that has requested a deletion of a Prod-file to be in the same call as me and in a verbose way confirm the deletion. But I will not have it any other way. I want control, confirmation and a clear concience after doing those kinds of operations in prod. Different story for nonprod and preprod, but in Prod you should always doubt yourself.

The bit about finding bugs/seeing code differently when viewing it as a pull request doesn't surprise me at all. Common advice to someone editing a paper/article/thing-they-wrote is to view it in a different format. Print it out, save it as a PDF, change the font if it's all you can do. Anything to make it look and feel different from when you wrote it. Helps you see it differently, and suppresses the tendency to read what you think you wrote instead of what you actually wrote. This seems like a similar principle, just for code.

12:10 If you are going to rm -rf on a production server ... just dont. In fact just dont SSH onto production at all. If you think you need to thats probably indicative of other (much larger, systemic) problems that need sorting out.

I've done this as tech support for a shared webhost, but it was just that single person's Wordpresses that were brand new. I still felt terrible. Zero backups between them and our hosting due to them being such a new customer. In the scenario of a CLI tool not responding, I'd sooner chunk strace up in another session on the pid to ensure it's doing something. It's that easy baby!

I'm ashamed to admit that while trying to generate white noise in my speekers, I've run the command "sudo dd if=/dev/random of=/dev/sdc1" instead of "sudo dd if=/dev/random of=/dev/dsp1" three times. I was young, though, but it certainly taught me to respect the root user... I just wish it could have done so the first time and not the third time...

At my first startup they were running a database in a container (6 years later i think this was a terrible idea but some people still do it). I was having some performance issues so I killed the container. Usually a safe thing to do since they meant to be ephemeral. Then i realized the db was gone. Neither me nor my boss knew that rhe other dev had made a backup. My boss was not forgiving. I cried a lot that night.

That is a message I dread to ever have to send... That I just nuked production royally to the point you need backups
I worked for one of the worlds biggest websites about 15 years ago. We experienced an outage covered by many major outlets. The root cause was a dev had written a stored proc to delete rows where the parameter to the sp was also the column name. So “delete from x where id = id “ just nuked the table. We of course had dba’s who dutifully reviewed this and ran it. When the dev had tested it the sql plus prompt told him he deleted 1 row - because his dev dev db had only 1 row. The dba was just incompetent apparently. Funny thing. The dev in question had just handed in his notice but was being kept on as a contractor for way more money. And the sites covering the outage all reported it as a large scale hack. I managed to escape the building before being dragged back to help.

You should approach production issues the same way aircraft pilots do: buy time. If you have any hysterics because "nobody can use our product", don't do things you don't know can fix it, do things that mitigate the issue, maybe you need to failover to a backup or something, but panicked rollbacks are how knight capital went under

I was a core developer on a project and sometimes we had to log into the database to fix stuff and resolve locks. We had the following rules, if my college were there I was not allowed to touch production (I have trigger fingers). Nobody are allowed to touch production unless there are two people watching and every line are completely rubber ducked and are run on a dev server first. Often times I would write the command execute and test it locally or on the test db and then send it to my college for us both to execute it together.

You can do this with a lot of commands by adding the -I flag per alias. For rm for example, it makes it so that if there's a lot of files to delete itll ask for confirmation.

this actually happened to me, that I mistakenly deleted most of the staging db. Test environment was in the next tab. I have not done something similar after. What helped most was naming terminals and having a +1 person on the call when doing something like this. Having another person present is most helpful

pro tip: have different background and font colours for every ssh session and root terminal tabs. It helps a lot. Especially if the one where you must not screw up has a red background.

On critical systems, two is one and one is none. One of the many problems with the situation is that they didn't have DB3, precisely for this event, and other events like this one. It is always an "overkill" until it isn't. And then, of course, all your extra copies, snapshots, etc.

I use different coloured terminals when I'm working with a production server. Green == dev, Yellow == staging, Red == prod. In a red terminal, I am REALLY careful what I do. It definitely helps.

Fun fact: GitLab could've likely recovered their DB data much faster by dumping the filesystem journal that was still in the Linux kernel at that point in time, and undeleting the files, as the journal preserves the old file metadata up until the computer is rebooted.

These seem like issues I'd expect in a startup, not gitlab. 15 YEARS ago we had a rule that any work done on a production server had to be done as a pair. Anything we did had to be done to staging first as practice. This significantly cut down on issues. (Of course, you want IaC for routine prod work.) Also, backup should be tested in a CI job, perhaps monthly. If it isn't tested, it probably doesn't work.
