Who are they hiring?51
Today was my last day of work, tomorrow i have officially left that place. It's a weird feeling because i'm not certain about the future.
The job was certainly not bad, and after all i read on devrant i'm beginning to believe it was one of the better ones. A nice boss, always something to eat/drink nearby, a relaxed atmosphere, a tolerance for my occasionally odd behaviour and the chance to suggest frameworks. Why i would leave that place, you ask? Because of the thing not on the list, the code, that is the thing i work with all the time.
Most of the time i only had to make things work, testing/refactoring/etc. was cut because we had other things to do. You could argue that we had more time if we did refactor, and i suggested that, but the decision to do so was delayed because we didn't have enough time.
The first project i had to work on had around 100 files with nearly the same code, everything copy-pasted and changed slightly. Half of the files used format a and the other half used the newer format b. B used a function that concatenated strings to produce html. I made some suggestions on how to change this, but they got denied because they would take up too much time. Aat that point i started to understand the position my boss was in and how i had to word things in order to get my point across. This project never got changed and holds hundreds of sql- and xss-injection-vulnerabilities and misses access control up to today. But at least the new project is better, it's tomcat and hibernate on the backend and react in the frontend, communicating via rest. It took a few years to get there, but we made it.
To get back to code quality, it's not there. Some projects had 1000 LOC files that were only touched to add features, we wrote horrible hacks to work with the reactabular-module and duplicate code everywhere. I already ranted about my boss' use of ctrl-c&v and i think it is the biggest threat to code quality. That and the juniors who worked on a real project for the first time. And the fact that i was the only one who really knew git. At some point i had enough of working on those projects and quit.
I don't have much experience, but i'm certain my next job has a better workflow and i hope i don't have to fix that much bugs anymore.
In the end my experience was mostly positive though. I had nice coworkers, was often free to do things my way, got really into linux, all in all a good workplace if there wasn't work.
Now they dont have their js-expert anymore, with that i'm excited to see how the new project evolves. It's still a weird thing to know you won't go back to a place you've been for several years. But i still have my backdoor, but maybe not. :P16
A recruiter called me today. I had to barracade myself in the laundry room to hear him, and still needed to ask him to repeat himself 7-8 times. he spoke at what must have been 15% volume with a super thick Indian accent. He also couldn't pronounce a full third of the terms.
Here's how it went.
recruiter: you full-stack dev? what experience?
me: yes, about 8 years, maybe 10.
recruiter: you know C#?
recruiter: you know java? tomcat? spring?
me: no, I don't know Java.
recruiter: you know react? angular? apache? node?xml? json? html?
me: yes. yes, angular 1. yes, yes, ...
recruiter: ok, i email you java job posting
me: I don't know java.
recruiter: ok, i email you.
Recruiter used "email java job posting." It wasn't very effective.
Recruiter moves quickly! Recruiter used "did you get my email? email" immediately after. It was super effective! @Root becomes angered!
@Root becomes enraged!
recruiter: what [???] [?] [???] [??] java [???] [??] [???] okay
recruiter: You know C#?
me: No, I still don't know C#.
recruiter: ok thank you for time. 😡 *click*
What just happened?
I really don't understand their species.39
"Almond, I thought you said the cause of the outage the other week was that our server crashed?"
"The Tomcat server crashed, yeah. Not the physical server." (And you won't give me the time or budget to spin up any kind of redundant one, but that's besides the point...)
"Ok, but I've spoken to ops and they say none of the servers have gone offline in the last month?"
"Yup, the physical server was fine, it was the Tomcat server running on it that crashed."
"...so the server didn't crash?"
"We're mixing terms here. There's two things that can be referred to as the server. One is the physical machine, and one is an application running on it. The physical machine was fine, but
the application running on it crashed."
"What?! It's a very simple question. Did the server crash, or didn't it?!"
I just can't understand what will lead an so called Software Company, that provides for my local government by the way, to use an cloud sever (AWS ec2 instance) like it were an bare metal machine.
They have it working, non-stop, for over 4 years or so. Just one instance. Running MySQL, PostgreSQL, Apache, PHP and an f* Tomcat server with no less than 10 HUGE apps deployed. I just can't believe this instance is still up.
By the way, they don't do backups, most of the data is on the ephemeral storage, they use just one private key for every dev, no CI, no testing. Deployment are nightmares using scp to upload the .war...
But still, they are running several several apps for things like registering citizen complaints that comes in by hot lines. The system is incredibly slow as they use just hibernate without query optimizations to lookup and search things (n+1 query problems).
They didn't even bother to get a proper domain. They use an IP address and expose the port for tomcat directly. No reverse proxy here! (No ssl too)
I've been out of this company for two years now, it was my first work as a developer, but they needed help for an app that I worked on during my time there. I was really surprised to see that everything still the same. Even the old private key that they emailed me (?!?!?!?!) back then still worked. All the passwords still the same too.
I have some good rants from the time I was there, and about the general level of the developers in my region. But I'll leave them for later!
Is it just me or this whole shit is crazy af?3
✔Grails is broken

Stack Overflow. Everyone uses it but everyone seems to hate the community. I very often read about someone getting down voted and they all say the same thing - "I have no idea why".
I have spent a lot of time moderating SO posts, which gave me a lot of reputation and medals. I find it fun to help people and it feels good to give back to the community.
I have asked a bunch of questions and I've never gotten a single down vote, which leads me to believe everyone of you that is constantly getting down voted are doing something wrong. Because the posts I see getting down voted are fucking stupid questions that either lack information or contain too much information.
Server java error
Why is my server not working? I am using Tomcat, port 8080 and I'm getting IOException.
Webpack configuration not working
My webpack is not a working, why?
[entire webpack config]
What the fuck are you expecting asking questions like these?? No one gets paid for answering your questions, so the least you can do is write a CLEAR AND UNDERSTANDABLE question. I'm not gonna tell you how to do it because there's A LOT of information on how to do it.
People devote hours and hours to helping others on SO, and of course they get fed up with the stupid and lazy questions. That community is not about being nice, it's not about making people feel welcomed, it's about QUALITY OF CONTENT. No one is crying when they find a superb question + answer, right? That's the result of a community not accepting low quality content.
So please, the next time you get a down vote on SO - do not come here whining about it but instead take a look at what you have posted there and ask yourself if it could have held a higher quality.
"Sooo, children of the village, what are we going to write front-end in?" - I said to my infant students.
"Typescript with ts-loader/awesometypescript loader for webpack" - simultaneously yelled the kids.
"Exactly! Brilliant! And now, what are we going to be writing back-end in?" - asked I then.
The kids yelled: "PHP 7.2 with Laravel, or Go with Gingonic and juliensmith/httprouter, or Typescript without loader, with express/koa"
Truly stunned with their excellence, I asked "Well, now you 100% ain't gonna get it right - what are we going to be writing a desktop application that doesn't require a lot of native functionality and preferably, cross-platform in?" And the kids didn't hesitate to yell happily "Typescript targeting Electron", which has only brought tear to my eye.
"A native ms windows app?" "WPF under C#"
"A native gtk app?" "Vala"
"A native KDE/XFCE app?" "Cpp/Qt"
"A native mac app?" "Swift3.2/4"
I was in tears, just thinking about what future these kids have, but suddenly I have noticed one of kids seemed puzzled. It was Pajeet, an indian guy, ugh, his mom was a bitch. I asked him "What is wrong, little acoustic?" "But I like Java, and I would like to make back-end with Tomcat!" he replied. "Ooooh :3" cutely I moaned, trying to reach the handle of the table locker "I've got something just for you". I pulled out a rope, with sewed-in spikes, covered in drool and piss, came up to Pajeet and tenderly put it around his neck, making a knot. Pajeet fell under the table, and I got fired.8
I was gonna write some code, but Tomcat stopped by
I was gonna write for browser or Node but Tomcat stopped by
Now I’m covered in cat hair and I know why
‘Cuz Tomcat stopped by

I was gonna follow through but Tomcat stopped by
I was gonna study algorithms too but Tomcat stopped by
Now I’m DevRanting this song and I know why
‘Cuz Tomcat stopped by

Realized I hadn’t subjected you guys to cat photos.
The brown cat is Robert Lazarus (the rescue named him Bob) and the white and brown cat is Dylan Thomas (rescue named him Dylan).
Bobcat died as a kitten (thus his middle name) and was brought back to life, but was blind for a bit as a result. According to legend, Tomcat acted as his seeing eye cat when he wasn’t able to see on his own. Bobcat’s vision’s better now (though he still might have some issues as he’s a little iffy on balance sometimes), but the rescue didn’t want to separate the two of them since they were a bonded pair.
Loads of people wanted Tomcat but didn’t want to take a chance on a zombie cat. Which I’m constantly thankful for because they’re awesome. Even if they steal my keyboard and try to eat my notes and try (and succeed) to jump on me while I’m trying to cook because they want to play with the feather toy that’s been hidden (not so well!) on top of the fridge and know it’s their best shot at getting up there.11
manager: "hey, we have this old java software running and need it to be compatible with our brand new crm system"
me: "okay, i've never workes with jsp before, but i'll have a look at it"
code: undocumented, who would have guessed
manager: "oh and btw. you must test your code on our live system, with our production database, but make sure not to brake anything, our last backup was 20 months ago."
“Overhearing powers of the Fullstack dev”
We have an internal control panel (BEEP) to manage our dev Tomcat instances. The other day, with one of my muggle friend, I was trying to restart an instance. There’s a checkbox to clean the host tmp files and directories, ingeniously named as - Purge cache.
Innocent Me (to my muggle friend): bro would Purge cache delete the application log files?
__(Fullstack dev overhearing us)__
Muggle friend: Purge ca... (gets interrupted my the Fullstack dev)
Fullstack dev: so the thing is ... it’s like ... (gotta be consistent with the opening) what “npm purge” does is it deletes the files which are not being used.
Confused Muggle friend: bro it’s a BEEP option to clean the tmp dirs.
Fullstack dev: oh I thought you guys were talking about “npm purge”
Angry muggle friend: then WHY THE FUCK did you answer if you didn’t know [...] the fuck we were talking about.
Calm fullstack dev: FYI. Might help you someday.
Deeply-hurt Me: (what the fuck is “npm purge”). Hey man do you mean “npm prune”? Because they don’t have an npm purge. And what do you mean by “it deletes the files which are not being used”?
Confident Fullstack dev: NO
Me: (cries in npm)
More to come!3
When I began my sandwich course in a big French company, I was dreaming about cutting edge stack, rocket computer and stuff...
I was disappointed when I came to my office with an old Windows 7 computer, coding via LANDesk to an old server with Windows Server 2008 on it, with Eclipse ... INDIGO...
I have to use Java 1.7 ...
PRTG for monitoring...
Microsoft SQL Server 2008 ...
Coding on a codebase where, indubitably, MVC pattern was just a weird thing in books.
Well it really disappointed me.
Luckily, the Information Service was very open minded and gave me a laptop with Fedora, 3 screens, updated the servers, and let me update the stack, with Java 10, Angular for the front, they are okay for using Docker.
So ... even if it seems to be fucked up, there’s still hope !!4
Don't waste your time - they said.
Use Spring - the good ol' framework - they said
It's not slow - they said
me: ignores them, builds a custom jetty-based webserver with the same functionality Spring+tomcat can offer (mappings, routings, etc).
My app: boots up completely in <300ms, while Spring tutorials say a hello-world app takes 3+ seconds to spin-up http://websystique.com/spring-boot/...
me: already set for deployment in lambda. I bet I can tune it up even further with lazy-loading if I really have to...
Moral of the story: sometimes bare-bones solution is a better choice: more performant, more extendable, more testable, more lightweight.
That, dear folks, is the classic LESS IS MORE :)12
When I started my current job I fucked up my first deploy ever so slightly but In the end managed to get it going with a quick hack (unpacking our war file modifying some properties and a jsp page before restarting the tomcat server )
One of the senior developers was having a really bad day and decided I was who he was going to take it out on, calling me a cowboy (in the Uk that’s a bad thing) blah blah, being really nasty and condescending to me.
I was about ready to shout at him as it was his dodgy configuration that caused the issue in the first place, but instead I took a deep breath and firmly (but calmly) told him never to speak to me like that again or we would have a problem.
5 years later he’s never spoken to me like that again and is actually a pretty decent guy.
Moral of the story people have bad days but also don’t let people take the piss.
Who has the craziest (not largest per se) Production stack?
I just found out we have tomcat webapps, calling Angular, which is calling Java to call a Perl script.5
I've been away from devRant (and other social media) for a few days because I thought i needed to concentrate on a project that I'm currently working on.
I just realized that I need this, I really need to rant! There is just too much to rant about. Like how fuckin annoying tomcat is, (don't ask me, someone is paying for me to use it), or how eclipse is happily hugging over 1gb of my ram, ( again don't ask), meanwhile vscode is doing just the same thing (debugging a tomcat server) with less than 300mb! There's so much to be annoyed about that I truly don't know how I was getting along before devRant.2
This week I got a promotion after being a junior for a year. Boss said Im a medior now and my monthly salary raised with 400 euro per month
Feels good but what feels bad is that a coworker of mine which has been contracted recently without any development experience is still making 400 more a month..
The thing is that this "developer" wanted to become a Java developer, he has been given time during work to study Java and in the meanwhile join the team thats working on a saas product (my team, where im lead dev)
During the 3 months ive counted a maximum of 10 commits and i was done with him which conflicted in a very bad vibe at the office.
During a refinement I asked if everybody understood what needs to be done, no questions asked. Next day when i was working at a clients office on another project 9 am i git a Skype message "Can you tell me What to do? I have no idea" where I replied "you should have asked me yesterday, i am not going to help you unless u come up with a question that makes sense.. what have u tried urself?".. Well then he got mad and stopped doing what he was trying to do.
The next morning i talked with him and we agreed to have a 1hour session to talk him through the user story. When we were done, he said that he understood and was going to work on it.
Next day I check, no commits, so during stand up i confronted hmj with this and he admitted hes been lacking and wanted to talk with the boss and me after stand up.
Well he admitted things were going to fast to keep up for him because he is doing some sysadmin stuff aswell.. the plan of becoming a Java dev was now history and he left the team..
Now he is just doing some sysadmin stuff but its been 3 days that hes been saying today ill setup a tomcat on the servers and give you SSH acces to deploy your .war files, today I finally gained access but he couldnt figure out how to move the war to the webapps folder.. And i wasnt allowed to transfer it to there..2
Apache Tomcat vulnerability "GHOSTCAT" allows read conduct files and implant web shells. All versions in the last 13 years vulnerable.
According to Security Researcher of Chaitin Tech : Due to a flaw in the Tomcat AJP protocol (the channel for Tomcat to connect to the outside, pass them to the corresponding web application for processing and return the response result of the request), an attacker can read or include any files in the webapp directories of Tomcat.
For example, An attacker can read the web-app configuration files or source code. In addition, if the target web application has a file upload function, the attacker may execute malicious code on the target host by exploiting file inclusion through "GHOSTCAT" vulnerability.
Apache Tomcat has officially released versions 9.0.31, 8.5.51, and 7.0.100 to fix this vulnerability.5
Boss: We need you to configure our Apache Tomcat server for SSL.
Me: Okay, what version of Tomcat is installed?
One of my interviews....
Interviewer: Do you know the welknown hack that increases the speed of embedded tomcat two times than default??
Me: what?? it even exists???
interviewer: yes... it exists... I know it... normally I share the answers with the interviewees... are you interested to hear the hack???
Me: Hell yeah...
Interviewer: ohh no... I will not share with you...
interviewer: I don't like your current boss...
Me: Fuck my life(inaudible)... facepalm..3
Best shameless hack: installing a Windows Service to restart Apache Tomcat every night at 2am on a clients' server coz the jsp application kept leaking memory and crashing tomcat. So bad, yet such a timesaver.1
Long time ago i ranted here, but i have to write this off my chest.
I'm , as some of you know, a "DevOps" guy, but mainly system infrastructure. I'm responsible for deploying a shitload of applications in regular intervals (2 weeks) manually through the pipeline. No CI/CD yet for the vast majority of applications (only 2 applications actually have CI/CD directly into production)
Today, was such a deployment day. We must ensure things like dns and load balancer configurations and tomcat setups and many many things that have to be "standard". And that last word (standard) is where it goes horribly wrong
Every webapp "should" have a decent health , info and status page according to an agreed format.. NOPE, some dev's just do their thing. When bringing the issue up to said dev the (surprisingly standard) answer is "it's always been like that, i'm not going to change". This is a problem for YEARS and nobody, especially "managers" don't take action whatsoever. This makes verification really troublesome.
But that is not the worst part, no no no.
the worst is THIS:
"git push -a origin master"
Oh yes, this is EVERYWHERE, up to the point that, when i said "enough" and protected the master branch of hieradata (puppet CfgMgmt, is a ENC) people lots their shits... Proper gitflow however is apparently something otherworldly.
After reading this back myself there is in fact a LOT more to tell but i already had enough. I'm gonna close down this rant and see what next week comes in.
There is a positive thing though. After next week, the new quarter starts, and i have the authority to change certain aspects... And then, heads WILL roll on the floor.1
Dear EU haters, it seems you have reasons to forgive European Beast some of its sins. EU wants to pay since coins for a bug bounty on FOSS. List includes KeePass, VLC, Putty, 7zip and Tomcat.
teaching myself Java servlets
ide refuses to recognize my tomcat server
me: ...... no one's using java servlets right?
*nods to self, gets up and leaves laptop*4
It's frustrating when network guy blame tomcat is not running and hence something wrong with application without fucking checking proxy settings. Fucking waste my 2 hours and in the end he looks like idiot. Good Morning.
It isn't much, but the MVC application now reads data from the Linux LAMP server and prints the SQL data back to the client. Biggest hurdle was the fact that my Linux host blew up three times over the week, but hey, how else are you going to learn Linux servers?
Moving into spring framework self-education in July. Hopefully it's a little less painful than Apache Tomcat.
I regret moving to backend. I loved the days when I used to write lines of code and refresh my browser for the changes to be displayed on the screen. I loved seeing the output of my code, the code flow, the light weight text editor, the visual satisfaction and the chrome debugger.
Now I am fucked up, I am working on creating microservices for restful api. I am hating everything about it. The fact that I should compile the entire war, manually copy them to a webapp folder, restart my tomcat and wait for 5 minutes just to see my code, and the text editors are just a pain in the ass, the debugger sucks too.
I was so looking forward to being a backend Dev because I thought Java was cool and I also was fedup with cross browser optimizations on the front end. Now I would gladly write a streaming service foe ie6. Spring has fucked me up so hard
God save me from this mess.6
Ugly, Heavy, Shitty, won't select tomcat 8.5 from its shitty server's list.....
Back to my lovely simple text editor and terminal... I can rely on them always.4
Another day, another task that requires magic. I'm stuck trying to connect hibernate envers and tomcat. Both work fine on their own, but now envers needs session data and i see no way to make that work because THAT GODDAMN ENVERS-LISTENER HAS NO WAY OF ACCESSING THAT INFORMATION WITHOUT GODAWFUL INSTABLE HACKS.1
My biggest challenge has been moving away from an unmaintainable Java/Tomcat/Spring Security application server to a Node.js/Express application server. That handles single sign on and two factor authentication. In 2 weeks.
I'm a front end dev. I'm sure it's fine 😓6
So I got access to a new Centos server. I had to install applications like Mysql, tomcat etc. The install was easy but configuration to be done were fucking headache. Admin guys were such Assholes that they dint care much to help. It took me 3 days to finally sort out and got things running. Yay! I believe I learnt a lot about Linux. Thank you Admin for being such an asshole✌️1
Ex-colleague asked for help in regards to an old project we were working at my old job
Him:"We're experiencing an internal server error. What do we do?"
Me:"Restart tomcat, dude"
Then I explained how by finding tomcat in ps -ef in a Redhat server, because he's a Linux noob and needed a lesson in how services works. Proceeded to explain how to restart tomcat with an online guide available.
Him:"Couldn't find tomcat in any of the servers"
Me:"Are you sure? Send me screenshots"
Him: sent screenshots
Me:"it's there. Look carefully."
Him: finds it and proceeded to restart tomcat.
Him: "Can't restart. Some catalina.sh is stopping it."
Me:"Figure it out. You can do it".
Half a day passed...
Him:"I give up. If I restart the server, will tomcat also restart?"
Me:"Up to you man. It will work but it's bad practice."
He restarted the server vand now everything is honky dory. I feel sorry for him though.2
I was fine with Eclipse. Then everyone around me told me that Eclipse is old and IntelliJ is new and super cool and makes me super fast and much more productive. Finally in our company we got a Ultimate 2018 license and I started to use it. There is a function: import from Eclipse. Hey cool - let’s import and go... but no. After importing I needed one day to get that running. But I’m not really convinced. After that... ok let’s try another project where colleagues have used IntelliJ already. But after checking out - that also didn’t work well and I spent the whole day it running locally. Although it’s a maven project. Up to know I think Eclipse is better in handling Tomcat and better shows the version control state of files. And for me the workspace concept of Eclipse seems to be better than the project concept of IntelliJ. But maybe I just have to get a better understanding of IntelliJ. Hopefully I can do my first coding in IntelliJ tomorrow. Maybe then I can see all the benefits. So far...4
If you have striggled a lot to find good diagram makers/editor. Here is the one.
draw.io is free online diagram software for making flowcharts, process diagrams, org charts, UML, ER and network diagrams.
Try it. Its open source. Even the code is open source, you can get the war and run it in you tomcat offline...
I am listing few type of diagram you can draw are
1. ER Diagram
2. UML Diagram
3. Business process workflows
4. Bootstrap components for mock screens
6. Floor plan
7. Network diagram
Professor to the whole class: Apache tomcat runs on port 80 which is the same port used by skype
Me: (change the port of tomcat to something else, obviously)
Professor: Kill Skype
i fucking hate that professor for whom i have to work on laboratory project right now.
well that wouldn't be not so bad if...
we wouldn't have to fucking debug his mistakes he put into the fucking prepared code AND his fucking useless instructions how to set up the project for eclipse the first time. not to mention his fucking requirements which make no sense
oh yeah im a student. i can always go and ask him for help if i need any...
i have another 70% mandatory course at the same time and that fucker refuses to upload hos sheets in moodle and answer even one fucking question via mail. not to mention no support if I am there unless i have eclipse setup. even through the projects should be build using gradle...
and all that wont even give us a grade. no ita simply a pass or fail part of the module which the course is part of.
have i also mentioned that the whole shit should be done in 20 hours according to the schedule9
Tomcat catalina apache server needs to automatically restart each time you change at least 1 line of a CSS code in order to apply those changes on the web page and guess what

I am trying to install eclipse for college
Windows defender blocked it because it found malware virus in it
Disabled windows defender
Waste my time to download again
Kaspersky blocked it because it found multiple trojans
Kaspersky saved my computer over 30 times from real damaging viruses
Disable kaspersky too
Waste my time squared download eclipse again
Import tomcat v8
Has anybody ever had to deal with migrating a tomcat webapp to a jboss server? It's fucking bullshit.
So, I decided over the weekend that I would move my entire dev environment to Linux. No Windows on the laptop and only as a backup boot system for my home PC. I wanted to wean myself off of Linux as only being a VM and move to the full blown desktop.
I can only describe my experience to that of having your first kid: lot's of crying and joy at the same time.
Things I've learned:
1. The install is amazingly painless. Wi-Fi and Bluetooth work straight out of the box no configuring needed.
2. OH MY GOD THE CUSTOMIZATION. Rocking Arc Dark theme on Gnome3 = EVERYTHING IS
ALWAYS DARK MICROSOFT WHY IS THIS NOT A THING.
3. Getting Java servlets to work has been hell. I gave up trying to get them to work in eclipse and moved over to IntelliJ. More trial and error before I can figure out why tomcat won't fucking work in eclipse but it's fine in IntelliJ.
4. The UI and overall work flow has been improved after getting past the learning curve. Gnome3 is way better from when I tried it out 4 years ago.
5. Vim has a steep learning curve but I am starting to understand the net benefits of it. It'll probably be a solid month before I get good with it.
6. Loosing Microsoft Office has been a little bit of a challenge but their suite is online so....meh. I do miss Visual Studio though, and am still looking for an adequate replacement for C++ and C# development.
Overall it's been a challenge but I think it's been a net gain. Now if only I could get the whole sys-admin team to use it. ;)12
Without a doubt it has to be the internal company search engine/file finding tool @thewamz and I wrote.
The company has a wide UNC network with files scattered all over the place and they need a way to keep track of where the files get moved to (they can and do get moved). The original tool was written in Java/Tomcat and didn't use any frameworks or utilities beyond custom written ones, no orms, and the SQL was just raw strings. The program didn't take into account that files might be moved or deleted so it never removed anything from the database, it just kept adding files and never removing them.
It however never stores files itself, just links to files elsewhere on the UNC network.
It took six months to get it into what might be a stable beta or release candidate state. The user interface is good, very simple and intuitive, the whole thing was rewritten in python/django, there were issues with utf 8 (and mysql not fully supporting utf 8 in its own utf 8 mode), we added a regex search mode (which was sorely lacking), the search used to take up to fifteen minutes however we sped it up to less than a minute (worst case when a user simply puts "^$" as the regex search). It has a multi threaded design which does some checks to ensure it doesn't spawn too many threads and get stuck in constant Gil switching. Still some bugs to fix, like moving the processing of results returned by the server in a web worker so that the content widget doesn't lock up processing millions of search results and moving the back end to use asynchronous python might gain a performance boost. But on the whole I think the system is ready to replace the older system that all the users are frustrated with and constantly complain about.
However the annoying bit is... How to actually get the new system online, while I am responsible for the development of tools and their maintenance, I am not responsible for their initial deployment and that means I have no idea when (or even if) my new tool will even ever be released :/
How fitting because that just happened today: MOTHERF*CKING Tomcat.
Tomcat sucks with client side routing (e.g. in angular2).
How hard can it be to provide a web/application server which is properly configurable?
I lost a whole day by trying to get an angular2 project deployed in Tomcat.
But that's not enough.
There seems to be no way in Tomcat, short of writing to XML config files and including one jar library, to disable routing go a webapp. And you need to do this when you have a single page application with client side routing.
But yeah, dear boss, I get the part where Tomcat is lightweight, easy to use and does most of the work for you: when you do not use it.
As a side note, so that nobody thinks I have a grudge against the Apache guys: I see the advantages of a Tomcat if you have multiple webapplications written in Java which you need to manage our if you use it as an embedded application server.
But there are just some occasions where a plain old Apache Webserver is better suited.
Another side note: if I just embarrassed myself because those are settings which can be easily applied feel free to tell me 😉2
target env: tomcat 8 on linux
devs local env: uses springboot 1.5
me: hey it does not work as expected.
dev: but it works on my local machine.
me: have you tried testing it with standalone tomcat maybe integrate it on intellij or containerize perhaps?
dev: (refused to test on standalone tomcat) it’s useless and it doesnt makes sense coz both are the same.
me: fuck let’s deploy your laptop on
My work product: Or why I learned to get twitchy around Java...
I maintain a Java based test system, that tests a raster image processor. The client is a Java swing project that contains CORBA bindings to the internal API of the raster image processor. It also has custom written UI elements and duplicated functionality that became available in later versions of Java, but because some of the third party tools we use don't work with later versions of Java for some reason, it's not possible to upgrade Java to gain things as simple as recursive directory deletion, yes the version of Java we have to use does not support something as simple as that and custom code had to be written to support it.
Because of the requirement to build the API bindings along with the client the whole application must be built with the raster image processor build chain, which is a heavily customised jam build system. So an ant task calls out to execute a jam task and jam does about 90% of the heavy lifting.
In addition to the Java code there's code for interpreting PostScript files, as these can be used to alter the behaviour of the raster image processor during testing.
The server isn't much better though. It's a tomcat based application that was written by someone who had never built a tomcat application before, or any web application for that matter and uses raw SQL strings instead of an orm, it doesn't use MVC in any way, and insane amount of functionality is dumped into the jsp files.
It too interacts with a raster image processor to create difference masks of the output, running PostScript as needed. It spawns off multiple threads and can spend days processing hundreds of gigabytes of image output (depending on the size of the tests).
We're stuck on Tomcat seven because we can't upgrade beyond Java 6, which brings a whole manner of security issues, but that eager little Java updated will break the tool chain if it gets its way.
Between these two components we have the Java RMI server (sometimes) working to help generate image data on the client side before all images are pulled across a UNC network path onto the server that processes test jobs (in PDF format), by reading into the xref table of said PDF, finding the embedded image data (for our server consumed test files are just flate encoded TIFF files wrapped around just enough PDF to make them valid) and uses a tool to create a difference mask of two images.
This tool is very error prone, it can't difference images of different sizes, colour spaces, orientations or pixel depths, but it's the best we have.
The tool is installed in both the client and server if the client can generate images it'll query from the server which ones it needs to and if it can't the server will use the tool itself.
Our shells have custom profiles for linking to a whole manner of third party tools and libraries, including a link to visual studio 2005 (more indirectly related build dependencies), the whole profile has to ensure that absolutely no operating system pollution gets into the shell, most of our apps are installed in our home directories and we have to ensure our paths are correct for every single application we add.
And... Fucking and!
Most of the tools are stored as source bundles in a version control system... Not got or mercurial, not perforce or svn, not even CVS... They use a custom built version control system that is built on top of RCS, it keeps a central database of locked files (using soft and hard locks along with write protecting the files in the file system) to ensure users can't get merge conflicts by preventing other users from writing to the files at all.
Branching is heavy weight and can take the best part of a day to create a new branch and populate the history.
Gathering the tools alone to build the Dev environment to build my project takes the best part of a week.
What should be a joy come hardware refresh year becomes a curse ("Well fuck, now I loose a week spending it setting up the Dev environment on ANOTHER machine").
Needless to say, I enjoy NOT working with Java. A lot of this isn't Javas fault, but there's a lot of things that Java (specifically the Java 6 version we're stuck on) does not make easy.
This is why I prefer to build my web apps in python or node, hell, I'd even take Lua... Just... Compiling web pages into executable Java classes, why? I mean I understand the implementation of how this happens, but why did my predecessor have to choose this? Why?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
Starting to work on a project as a trainee.
Trying to deploy the project on Eclipse.
404 Error when using my browser, while it did work some weeks ago, when I launch it to try.
"Hey, clean the project, and the Tomcat directory, and it will magically work."
It did work.
- load tests via web
- load tests via api
- figure out why the fuck hibernate started proxying Blob.class after migration rather than using jdbc implementation, like before
- fix ^^
- reconfigure tomcat to ditch random for urandom completely [still getting econnreset]
- continue conversation with sysadmin, tester, analyst, 2 PMs, infra architect, junior dev
- provide immediate support for analyst and tester as soon as they need it
- provide support to another dev on another project
and that's my today's todo list. I think I need more personalities [more threads] to keep going

I need to run a cloud Linux vm. My need is limited to running tomcat and about 10 web services- that's it. What I would like is an easy to use Linux flavor with a nice UI.
I need to know what cloud service and what flavor of Linux. And please don't get snotty with me because I have run massive applications on Solaris, AIX and HPUX - I am over doing things in a shell.2
so i was validating some user data using ajax in a facelets page.nothing was actually being validated when i deploy the application in tomcat..i thought it some sort of a bug on my code and after checking for the greater part of today i just couldnt find any bug.So i decided to deploy on GlassFish and it worked perfectly fine..fuck containers!!!1
Can I used vscode for java webapp projects? I already do some research about this but still no luck (or maybe I'm just too noob) I still can't run it on a tomcat server.3
I was trying to setup a Confluence install on my root behind a Apache Proxy..
I tried all the Atlassian Configs, my own Configs, but nothing works for Tomcat. I redirects you to the infinities of universe. My Apache Configs are all correct.
If you access Confluence directly it also works.
Tomcat you Ass start playing nice with the proxy fucker!
I hate Tomcat now. Go die!2
For the first time I paid for training(tuition, whatever) just coz my institution requires me to. And it was a complete waste of money. Teacher(or whoever he was), couldn't compile any of his programs. I had to look up tutorials for the entire thing myself, like I always do.
P.S. He was teaching server side java programming with struts and hibernate and using Tomcat as a server.
So this is more like an accident rather than a dissapointment but the thing goes like this.
I make multivariant stacks with vagrant, shell script loaded as stated in yaml config and every bit and piece done from there the only times it disapointed me was the first time i lost it and when i got asked to make it tomcat compatible, not that the person really needed tomcat but just because i called it a stack initialiser it must have tomcat support.
Wanted to install gradle on my raspi to build some projects for tomcat 7. I installed and configured tomcat7 already. Then i wanted to install gradle and i've got the following message from apt-get:
The following packages have unmet dependencies:
gradle : Depends: libtomcat6-java but it is not going to be installed
Depends: libjetty-extra-java but it is not going to be installed
It turns out, there is a dependency bug, and you can't install tomcat7 with cradle, because jetty depends on tomcat6.
Anyone ever try Tomcat debugging in VS Code? Specifically with Kotlin? I'm starting to get real fed up with IntelliJ tbh... it keeps screwing up when I have a multi-project/module workspace.
Yoo fellow devs... And sysAdmins??
We're tasked with migrating our apps from current HP UX server to RHEL...
Most of our apps run on Tomcat 7 and weblogic...
We also have Oracle DB Enterprise Edition...
Just wondering if any of you out there from the stone age have done this recently... Any tips.. Warnings... Advice on the matter??
Are there any good SAML 2.0 libraries out there for Node.js or Python?
Background: I'm working with SAML 2.0 SSO through ADFS at my current job. Our application server is a Java/Tomcat/Spring beast that I'm becoming more familiar with, and disliking more each time I toy with it. I'd like to move to something I and my team are more familiar with, and can better maintain/update/enhance.
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.
can anyone tell me where I can find sample server log data? I need access log and error log for Nginx, Lighttpd, Apache Tomcat, Caddy, Hiawatha and NodeJS. Do you know any website for this?6
