Migrated a first customer project from ASP MVC 5 to ASP.NET Core MVC 1.1.
Now running under Oracle Linux, with Apache and MySQL.

It's not finished yet but it runs (and I'm really happy with that). I like the new direction with .NET Core, open source and cross platform :-)

Just found out that Oracle Linux is a thing. That has to be the biggest contradiction I've heard of so far... Luckily I'm still relatively young.

fuck oracle. fuck my company.

Using Oracle VM Manager/Servers to host Oracle Phone transfer solution without support coverage from Oracle.

Requiring Unix sysadmins to update to latest release and not telling that we do not have coverage from Oracle if anything goes wrong.

Gues what.. We've updated to Oracle VM Manager/Server 3.4.5 which was released this year and it uses fucking XEN hypervisor version 4.4.4 which has been deprecated and dead since who knows when. Latest release of XEN is 4.11. But that is not an issue, whatever, enterprise, legacy software, etc.

This fucking update introduced memory leak on the hypervisor which has been reported as per xen 4.4.4 history. Furthermore, we have no support from Oracle which means that I have to dig through mailing lists and limited information on the net since oracle has freakin support wall on nearly each of the major bugs found on that shitty software.

I have no idea whether any newer version of xen will work with that old Oracle Linux kernel or not.

Furthermore, Oracle provided great documentation on how to rollback the fcking update. Reinstall the hypervisor. Riiiight. XEN does not have export/import feature.

eh

Well, I always say that if you going to make things a mess, do it a spectacular way. Today I kicked off a data import job that went bad, and in the process of canceling said job, I canceled myself, and the job went rogue, and became a zombie and ate ALL the system memory, bringing the server to a deathly crawl and throwing a dozen developers temporarily out of work for about an hour, before I was finally able to kill the zombie, and balance was restored to the Universe.

I used to be a sysadmin, which meant I was in charge of quarterly server patching. My team managed about 2500 servers, running various flavors of linux and legacy unix. The vast majority(95% or more) ran Linux(SLES). Our maintenance window was always in the overnight-- 10pm to 6am --so the stroke of 10pm would be a massive cascade of patching commands sent to hundreds of servers.

Before I was brought into the process, it made use of the automation product we were tasked by mgmt to use: Bigfix. It's a real piece of shit. Though we had 2500 or so servers, this environment was dominated by windows. All our vcenter servers ran it, and more importantly, our bigfix nodes were all windows machines. That meant that while we're trying to patch, the bigfix servers would get patched by the windows team. This would cause lots of failed and timed out patching, because the windows admins never quite understood that taking down the automation infrastructure would cause problems.

As such, I got tired of depending on a bunch of button-pushing checkbox-clickers who didn't know shit about shit, so I started writing an ssh-wrapped patching system. By the time I left for my current job, patching had been reduced to a single command to initiate each group's patching and reboots, and an easy check to see when servers come back up. So usually, the way it worked out was that I would send patching orders to 750 machines or so, and within about 5 minutes, they would all be done patching, and within another 20 minutes all the ones that required rebooting but about 5 would be done rebooting.

The "all-nighter" which happened every time was waiting for oracle servers to run timed fscks against a dozen or so large filesystems per server, because they were all on ext3/4, which eats complete shit. Then, several hours later, as they finished, I would have to call the DBAs to tell them to validate their shitty servers.

RDBMS class: I have to fucking attend every class even though our lecturer just reads slides from Oracle to us.

In order to pass that module, we have to take the exams on their shitty website full of stupid questions, I.e. "Oracle academy is beautiful? a) true b) false" (I put false and they obviously marked it as wrong, ffs).

Multi-user operative systems: I was the one teaching our lecturer stuff on Linux.

WHY THE FUCK I CANNOT STAY AT HOME AND BE FUCKIN PRODUCTIVE INSTEAD?!

The only fucking interesting class is Data Structures & Algorithms and they pretend that we also attend every other useless class. FUCK YOU!

PS: I know the 90% of the stuff they are trying to teach us because I actually want to learn something and I know how to use Google, but no, I have to waste 2 hours on the bus every single day I have lessons.

When you dual boot ubuntu and windows, then decide to remove Ubuntu because,who ate you kidding, you're not actually using it, then you get bored and want to try the new Linux distro that branched off from arch and vms at the same time so now you're experiencing the wonders of chakra on oracle virtual box....🤔

LINUX. I'm sure everyone heard this term. But I still don't know why do people want to give up their life and try this piece of crap. I know many of you might be offended, but, to hell with that. When I heard about the Linux, and everyone was praising it about it, I thought that I should give it a try. So, I installed Ubuntu (obviously, because I was a beginner) and the installation failed. I thought that I've made some mistake. Tried again, FAILED. So, I waited for next version. After downloading and trying to installing it, Voila. I installed it. Then comes the part when I actually started using it, for as simple as watching a video. I didn't play. It gave an error of some codec was missing. I installed the codec and then I payed the video successfully. Then, I want to install the Oracle Java Development Kit, and literally it was a pain to install. It took me half an hour to install and configure it. Then after using it for a couple of days, I found that my WiFi was acting weird. I booted up my Windows just to check it and it worked perfectly on windows. Then why the heck was it not working on Ubuntu. Don't know. On searching about it, I found that my WiFi adapter's driver was having some issues. Then after using it for more days, something very weird happens, the Ubuntu booted but with terminal only. No GUI, No Unity, nothing. I against searched for it, found some commands, ran it and it started normally. So, the point that I'm trying to make is that even for simple and basic tasks, I always have to search about it every time to get it working. I mean if their are so many steps to be taken for every simple task then why people keep on recommending it. With the Linux installed, I was very much distracted from my primary work. Instead of doing my work I was searching for installing JDK. I mean wtf. In Mac or Windows its as simple as downloading the file, installing it and you're done. But in Linux I don't know. And the whole Linux community thinks that Windows sucks. I mean on windows I was more relaxed and more focused on my work. Whenever we search for the Linux, many people say that Android is a Linux. I get it, but in Android, many developers have worked very hard to make it as what it is nowadays. But what about Ubuntu, Fedora or any other distribution. I haven't seen any distribution which makes me feel that I wanna use it again. None of them. So, Linux is not a great OS according to my experience

Started my first programming job in 2014 with experience in Linux and PHP. Employer asks shortly after hiring me to learn Oracle Forms 6i. What year is this again? 😂

For my next internship, i need a Linux distro, which is easy to use and which doesn't need a Lot of resources while using it in Oracle Virtualbox.
Which distro would you prefer, i think About ubuntu but I'm afraid that it would use to much of my limited resources so that it is nearly impossible to code with it.

Does anyone have a good tutorial on how to get Oracle database working on a Linux distro preferably fedora? Any help is appreciated

Oracle 11g DB or whatever version it was!! You need a fucking windows machine to install it, doesnt install on Linux or Mac!! I am a MySQL/Postgres guy, working on it was a nightmare, permission issues, and you need the oracle instant client on your system to communicate with windows, which works after a zillion errors!!

I love linux because i dont have to forced to do frickin update like windows did.
Because i have an experience after update linux mint i cant even start the main GUI program. After boot only show blank console. It seem linux update broke the compatibility between my graphics card.
At least now i dont have to update because thats an option. The output of update is not different than windows.there is a chance you broke your OS.
But the struggle is when i need to install new app in linux. Sometimes need more than hour to find out why it doesnt work from the first time.
Any help here?
So this start from the office. In the office i usually use low spec laptop that work slowly. Then i found this IDE called rapidclipse. Its very promising with GUI builder and can build cross platform mobile app using only java built on top vaadin framework.
When i use it on low spec laptop hackintosh at office it work well although it take more time than other kind of eclipse and i dont need to install any kind of app again, just download-install-create new project-run on tomcat-work well.
Then i go to home to try this new tool , IMO my low spec PC still have more power to run something than old hackintosh. Because usually i use android studio with no problem. In the old hackintosh it went too long to build gradle only.
Then i install rapidclipse, then run desktop shortcut. Then it said i need to install correct java to use correct JavaFX.
After search on SO they said i must install jdk from oracle.
Ok so i got openjdk in my linux.wtf what is the different idk but dont have time to find out.
I install jdk from oracle.
Than finally can open the rapidclipse.
Wow , this gonna be fun.
Then create new project. Just a new project.
So im waiting. I see the progress at 10%. But still no increment on that.
I switch to other app for several minutes.
Then when switched back th app still at 10% and now is at no responding state. So i force close.
After that open rapidclipse again.
The previous new project can be opened. Yay, i think.
But so many error there. Omg.
So i create new project again.
But, but, i just repeated the first error then close again then try it again for several time. But still same output.
After an hour, i give up.
But still, why , just why it work like this. No error or whatsoever.
Back later i have a problem like this on different app.
Idkwhy.
