I'm a DevOps engineer. It's my job to understand why this type of shit is broken, and when I finally figure it out, I get so mad at bullish players like AWS.
It's simple. Install Python3 from apt.
`apt-get update && apt-get install -y python3-dev`
I've done this thousands of times, and it just works.
Docker? Yup.
AWS AMI? Yup.
Automation? Nope.
WTF? Let's waste 2.5 hours and figure out why this morning.
In docker: `apt-cache policy python3-dev` shows us:
python3-dev:
http://archive.ubuntu.com/ubuntu focal/main amd64 Packages
But in AWS instance, we see we're reading from "http://us-east-1.ec2.archive.ubuntu.com/... focal/main" instead!
Ah, but why does it fail? AWS is just using a mirror, right? Not quite.
When the automation script is running, it's beating AWS to the apt mirror update! My instance, running on AWS is trying to access the same archive.ubuntu.com that the Docker container tried to use. "python3-dev" was not a candidate for installation! WTF Amazon? Shouldn't that just work, even if I'm not using your mirror?
So I try again, and again, and again. It works, on average, 1 out of every 5 times. I'm assuming this means we're seeing some strange shit configuration between EC2 racks where some are configured to redirect archive.ubuntu.com to the ec2 mirror, and others are configured to block. I haven't dug this far into the issue yet, because by the time I can SSH into the machine after automation, the apt list has already received it's blessed update from EC2.
Now I have to build a graceful delay into my automation while I wait for AWS to mangle, I mean "fix up" my apt sources list to their whim.
After completely blowing my allotted time on this task, I just shipped a "sleep" statement in my code. I feel so dirty. I'm going to go brew some more coffee to be okay with my life. Then figure out a proper wait statement.7 -
!rant, TL;DR at the bottom
Holy fuck, Yesterday, I got absolutely schooled by a literal newbie.
And I mean, NEWBIE newbie, the dude just started a Computer Science degree, and has been learning Java only for a MONTH. He has 0 prior experience with code or anything of the like, and he's somewhat of an Ars(Israel's version of a Gopnik).
So I was helping him with some stuff he didn't understand, and lo and behold his code was probably the most aesthetically pleasing and organized code I have seen in my 8 years of programming(I know 8 is not much, but It's at least above beginner level). The dude's a perfectionist, so I was like, "Okay, very impressive, but makes sense for perfectionism"(I straight up told him: "Damn, I've seen people with years of programming experience who can't learn to write this well, and you do this by default? I envy whoever's going to work with you"), and then I saw the way he writes checks(as in, methods that return a boolean) and I think I came.
The code was:
[First method in the picture]
And I know, it doesn't look as ✨ WOW✨ as I make it sound, but in my personal opinion this both looks much better and is much more readable than what I normally write:
[Second method in the picture]
and whenever there are longer or more complicated checks it makes it look like a simple puzzle that just fits in all the pieces nicely, for example in a rectangle class we had to write an 'isIn' method, this is how I wrote it:
[Third method in the picture]
His way of writing the same thing was:
[Fourth method in the picture]
Which I think is soooooo much better and readable and organized,
It's enough just looking at the short return statement to immediately understand everything that's going on.
"Oh, so it just checks if the SW(South West, i.e. Bottom Left) corner is above and to the right, and if the NE(North East, i.e. Top Right) corner is bellow and to the left"
Point of the story? Some people are just fucking awesome. And sometimes the youngest/most inexperienced people can teach you new tricks.
And to all of you dinosaurs here with like, 20+ years of experience, y'all can still learn even from us stupid ones. If 8 years can get schooled by a 1 month, 20 years can get schooled by a 1 year.
Listen to everyone everybody, never know where you might learn something new.
TL;DR: Got schooled by a local "Gopnik" who only started learning programming a month ago with 0 prior experience with his insane level of organization and readability.

I started as intern at the place. Worked unpaid for 4 months. Then they started paying. That's when shitload started. 5 web developers and 10 projects. 1 months later they fire one of us. Next month they fire another one. 3 developer and 8 projects. No documentation for they projects that were already started before I went there. Provide support for 3 year old project and nothing for reference. Salary was paid 10/15 days after the month war over. I couldn't take it anymore so I have a two months notice before leaving job. A month later all of the 3 android developers gave their notice. After we left, they haven't still paid us our final month's salary. Reason was it was not formal east of leaving and they projects we worked on haven't rolled out to market yet.
Talked and then mailed them the resignation two months in advance is not formal then I don't know what is.
Also how can the project be rolled out when there is specification change every 6 hour to 1 day on the project. Also we completed what was given to us and then the project hasn't rolled out because of new changes in the specification. -
How many of you are ready for the us-east-1 data centers to be offline for two weeks? Do you have standby copies of your data on the west coast already?

Today has been a weird day. AWS us-east-1 region has been having huge issues for hours now, with the console and multiple services down or erroring out. My day has been an odd mix of twiddling my thumbs with nothing to do and trying to calm down angry people who are also twiddling their thumbs with nothing to do.
I'm tempted to just log off Slack and leave an auto-reply of "Can't fix it, no workaround, leave me alone" so I can go back to bed.4 -
Anyone else having trouble with apt-get install in EC2 instance of region US-East-1? Seems it's too slow currently!
