So today I had a client come in and give me a free "broken" laptop that wouldnt turn on and was covered in grease and what appeared to be dog hair everywhere. So i go through my every day troubleshooting, found the problem and fixed it. Next i disassemble the entire laptop and just start air dusting and cleaning connections like crazy. Now I'm a proud owner of a really old school laptop that I can probably keep alive for another 10 years :) This will be a perfect machine to test arch linux on 😃18

The most crazy issue I've fixed was caused by a TCP behavior which I didn't know, called the "half-closed connection".
There was a third-party application installed on a production server which called a LDAP server for retrieving users information. During the day we had several users using the application and all worked fine. During the night, when the application was not accessed, something happened and the first call to the application in the morning was stuck for about 5 minutes before returning a response. I tried to reproduce the issue in a testing environment without success. Then I discovered that the application and the LDAP server were located on two different networks, with a firewall between them. And firewalls sometimes drop old connections. For this reason network applications usually implement a keep-alive mechanism. Well, the default LDAP Java libraries don't set the keep-alive on their connections. So, I found a library called "libdontdie", which force the keep-alive on the connections. I installed the library on the server, loaded it at the startup and the weird stuck behavior in the morning disappeared.2 -
I am the responsible for the atlassian Suite at work, as I maintain the systems, set them up, and stuff.
One day, our crowd (the authentication and authorization application) just went crazy. At like lunch time it could not connect to the AD anymore. No reasons. Throwing XSRF errors (cross site scripting), because http would connect to https. "won't do it, fuck you" it told me. Out of the blue. Noone changed anything. And yea, seriously. Noone did.
It just refused to connect (as connecting to AD is connecting yourself with you own api. And refusing yourself talking to yourself). It runs behind a proxy. Therefore http/https. Well, this worked for years. But out of sudden not anymore.
Yea. Fuck you.
It was reported some hours later, at like 3pm, as people could not login to the applications using crowd as authentication and authorization server.
Tried to debug the system, where nothing was did, to make it work. At best time to fail.
First workaround: if you are logged into one of the other applications of atlassian, just refresh the site, so your SSO token gets a refresh and you are signed on again.
Then I searched more and more. And more.
But nothing worked, nothing helped.
So I addressed an emergency maintenance, take down the whole Suite, restart crowd, to apply some changes to it's settings, not knowing what happening then, because all connections of SSO will then be released. Sent out the mail like 30 minutes beforehands.
While waiting for the window, I just typed my credentials... And redid, and redid, so to type and being bored.
Three minutes before the window...
It just worked again.
Well. Wtf. Serioudl
Just came back.
No Intrusion, no changes at all. Just came back, as nothing has happened.
Kind of best part of this story... A headhunter messaged me on my way home to offer me a job as an Atlassian Suite SysAdmin for a company, at kinda the double of my salary.
At first I was thinking to go there, and when someone then asked me sth about Atlassian just start to laugh and then leave still laughing...
But then I very nicely respond that I dont want to cry at work. And wished him best luck.
I am doing some bad upgrades now on our Suite. Very painful.
And I looked into the start scripts. Some Look like the untalented intern tells another one to write scripts. Seriously wtf.
Today I followed the guide to Update a confluence and change database to Postgres. Didnt work, Postgres error.
Try it again, jquery won't load. Next try, tomcat not starting anymore. Did same thing. Every fucking time.
Yea. Maintenance window to get a nice new export soon. Will only take an hour.
To switch database in confluence, you need to set it up very fresh. And then Import your export.
Export takes an hour at our system.
Importing maybe the same time. Hope it will work (hint: Nope).
Oh, can be nice also. Just tell the Bitbucket to migrate databases, there is a fucking setting for it. Enter new database, ready, go, finished.
At least they don't raise costs very much every kinda year.
Oh sorry, yes, they do.4 -
Growing list of asks to a team member that are unheeded:
1) Check in your code frequently
2) Stop the completion emails for your program
3) Stop using your personal UserID/Password to send said email
4) Create classes that do one thing
5) Reuse your database connections
6) Use DataTables and write to the database once and not a bunch of variables and write at the end of your crazy loop-if-else structures. -
I want to stay in the here and now where all the niceties are being added feature wise to everything and still work a decent paying job and get laid :(
wtf !
why do they constantly think they can take more and more and keep rolling everything backwards ! its stupid !
build back better should be code for 'bankrupt everyone and make life shitty and create diseased fucked up people who are incapable of forging human connections and or are scared to and/or are so tired out by a lack of novel thought and experiences their consciousness is just hiding until something new comes along so they don't want to kill themselves everyday'
i mean thanks people
always wanted my entire country to be filled with untrustworthy destructive crazy slaves. -
Amazing a repeat post
And a confession of the pain I'm in right now that barely describes it
Would have expected a "take meds you don't need because we know our part in the problem our slow destruction of life's meaning and your mind and talents and all purposes for social connections and our destruction of all worthy institutions but yeah take your meds crazy" hell I would have maybe even expected a description of you ruined peoples underwear and wandering hands heh1
