I see my boss interested in learning new languages as if it is gonna be some sort of holy grail but his logic remains the same.

I'm in a step of my life that I finally understand that this language fight is a total waste of time:

PhP is fucking delicious to deploy

Java is fucking delicious to work with spring boot

Python has a fucking delicious syntax and I wanna marry it

Go is fucking delicious to outperform others

Anyway, my point is that when you get the hang of it you should learn concepts and improve your logic instead of hoping language x is gonna save you, its not.

Front end + back end = Project finished.

This is my first full stack application that I spent a month working on. It's a basic database that holds car information and saves it to a SQL db. I built this using Java Spring/Hibernate for my backend and Node.JS/REACT for my front end. Mariadb handles SQL requests. REACT handles token requests for secure login, that was the hardest part of this whole thing.

I was going to comment on how frequently I feel like garbage and an inadequate excuse of a human being, but today is my birthday and this is the best gift I could get, a finished project from scratch.

I'm 29 today devRant. And I work over the weekend before going back to school, but at least I fucking finished something that I started.

...thanks, for everything. 😄

TL;DR
Management eats shit for breakfast

Context:
I am the sole Dev on a project.

Stack: Postgresql, redis, nginx,Java with Spring Boot, Neo4j.

I am the only one nearly familiar with : Redis, Neo4j and anything Java.

I'm gonna be on vacation for the next 15 days since they have told me that we where gonna be on a "testing/feedback" period.

My vacation was approved.

Today's meeting: we have a URGENT deadline to meet some criteria that might be the difference between have further investment or not.

Urgent deadline: last day of my vacation.

My face: poker

My thoughts: attached image

Series of events between me (Mi) and dude in office (DIO).

Instance 1
DIO: There is not psql installed on staging.
Mi: Install it.
DIO: YUM is not working.
Mi: *tries yum it works* It is
DIO: Oh. Didn't work earlier.
Mi: *blank* Make sure you install 9.6
DIO: Cannot find psql
Mi: *types psql, it is already installed*
DIO: Oh, didn't work earlier.

Instance 2
DIO: Made this change to the API, the endpoint is not returning the right value
Mi: *restarts server, shit starts working*
DIO: I am pretty sure I did that, don't know what happened.

Instance 3
DIO: Cannot alter role to give login to this db user.
MI: *runs alter role db_user with login* works
DIO: Don't know why it wasn't working before.

Instance 4
DIO: I have been stuck on this test for the past 1 day, cannot get the API to return the right data while the Rest Endpoint works fine.
Mi: You are hitting the wrong endpoint in the test.
DIO: Oh, I put an extra 's'
Mi: BTW you are testing Spring-Boot with that test and nothing else.
DIO: Yes but what if Spring Boot has a bug?
Mi: ok.

Hello devRant from Croatia!

Nothing like a day of breezy beach with sunshine and, to finish off the day, learn some Spring-Boot!

Enjoy your holidays!

First of all, I hate crammers so much. These people kill the industry without even understanding it. They turned interviews into exams, missed the point of hiring, and saw no distinction between knowledge and information all the time. They don't understand that if you can google an answer in five seconds, it's not knowledge. It's information.

They don't understand that questions like 'what will Python do if you delete an item from a dict while iterating over it' are complete nonsense. They don't understand that it's not 'dig deep'; it's just a bad practice that leads to errors, thus must be avoided. The fact of remembering 'RuntimeError: dictionary changed size during iteration' means that you haven't been avoiding it enough.

One more example. Which signature is correct?
- ApplicationListener<ContextRefreshedEvent>
- ApplicationListener<ContextRefreshEvent>
- ApplicationListener<RefreshedEvent>
- ApplicationListener<RefreshEvent>

Second. What's the point of forcing you to write compilable code in google docs? Do they really expect that one could possibly remember 'import org.springframework.beans.factory.annotation.Autowired;'? Seriously?

Third. Why do they expect me to know Spark, Java, J2EE, Spring Boot, Python, Kafka, Postgres, React/Redux, TypeScript, and work for miserable 70K EUR?

What's wrong with the European IT job market? Are they fucking nuts?

I'm home sick for 4 days now and I'm starting to become paranoid about being replaced because I caught one front end dev watching Spring Boot videos on Friday.

I'm the only one who works with it there.

Not feeling well.

In january 2023 i was contacted by a recruiter offering me a job position.

I DID NOT ASK FOR A JOB.

I WAS NOT LOOKING FOR A JOB.

THEY contacted ME.

Ok. So i went along with it and see how it goes. They probably wont hire me nor would i give a shit. Chatted with this recruiter for a while. She forgets to answer my message for 5 fucking days. Twice. Once because she was doing God knows what and the second time because she was on paid vacation. Fine i don't give a shit about you at all anyways.

So this recruiter chatting has been stretched out for several days. I think over a WEEK. So she forwarded me to their lead developer.

I applied to work as a full stack java spring boot backend + angular frontend engineer.

So:
- java backend
- angular frontend
- full stack
- shitload of devops
- shitload of projects i built
- worked with clients
- have CS degree, graduated
- worked a job at their rival company

What could go fucking wrong with all of these stats right?

During technical + hr interview (3 of us on google meets) they asked me what salary I'd be comfortable with.

I said $1500/month straight out.

keep in mind:
- In my country $500 or $600 is a salary for engineers per month
- You get a raise of +$150 which is around $750 after working for 1+ year
- You can earn $1000+ after you work for +2 years
- Rent here is $200-300 a month at minimun. And because of inflation its just getting worse especially with food. So this salary is not for living but for survival.

Their lead engineer gave me a WHOLE ASS FUCKING PROJECT TO BUILD and i had to code it within 10 days. Great so at least 17+ days of my fucking life to waste on these fucktards who contacted ME.

The project was about building a web app coffee shop literally what mcdonalds has when you order via those tablets. I had to build this in java spring boot and angular. I had to integrate:
- docker, devops
- barmen, baristas, orders
- people can order at the table or to go
- each barista can take 5 orders at a time
- each coffee has different types of fields and brewing time
- each barman brews each coffee different period of time
- barista cant take more than 5 orders for to go until barman finishes the previous order
- barista can take more than 5 orders but if those orders were ordered from table, and they have to be put in queue
- had to build CRUD admin functionality coffee's
- had to export them all of the postman routes
- had to design a scalable database infrastructure for all of this alone
- shitload of stuff more

And guess what. After 10 painful days I BUILT THE WHOLE THING MYSELF AND I BUILT EVERYTHING THEY ASKED FOR. IT WAS WORKING.

Submitted it. They told me they'll contact me within 7 days to schedule the final Technical interview after they review what i built. Great so another 17+7 days of my fucking time wasted.

OH and they also told me to send them THE WHOLE GITHUB REPOSITORY AND TRANSFER OWNERSHIP TO THEIR COMPANY'S OWNERSHIP. once you do this you cant have your repository back. WTF? WHY CANT YOU JUST REVIEW THE CODE FROM MY PUBLIC REPOSITORY? That was so weird but what can i fucking do argue with these dickheads?

After a week of them not answering i contacted them via email. They forgot and apologized. Smh. Then they scheduled an interview within 3 days. Great more of my time wasted.

During interview i was on a google meets with their lead engineer, 1 backend java spring boot engineer and 1 angular frontend developer. They were milking me dry for 1 whole fucking hour.

They only pointed out the flaws in what i built, which are miniscule and have not once congratulated me on the rest of the good parts. I explained them i had to rush those parts so the code may not be perfect. I had other shit to do in my life and not work for your shitty project for $0/hour for 10 days you fucking dickriders.

So they quickly ran over to theory. They asked me where is jwt token stored. Who generates it. How the backend knows to authenticate user by it. I explained.

What are solid principles. I said i cant explain what is it but i understand how it works, why its needed and how to implement it (they can clearly see in the project i just build that i applied SOLID principles everywhere) - but i do admit i dont know the theory behind it 100% clearly.

Then they asked me about observables and promises in angular. I explained them how they work and how subscribe method is used (as they can clearly see that i used it in the code). Then they asked me to explain them under the hood of how observables work. The fuck? I dont know and dont care? But i can learn it as i work there?

Etc

Final result: after dragging this for 1 fucking month for miserable $1500/month they told me: we can either hire you now but for a much lower salary which you probably wont be happy with, or you can study more these things we discussed "and know why the car leaks oil" and reapply back to us in 2-3 months!

Serbia. $600/month for

- full stack
- angular dev
- java spring boot backend dev
- jenkins
- ci/cd pipelines
- jira
- unit integration E2E tests
- kubernetes
- docker
- graphql
- postgres
- sql queries
- aws
- microservices
- deployments
- scala
- kafka
- maven/gradle
- bsc or msc cs degree
- in depth knowledge of
-- observables
-- design patterns
-- jwt and how it works
-- ssl certificates
-- solid principles

There is more but i forgot the rest

I can't figure out shit..
To be honest I created this profile just so I can write down somewhere what I am going through.
So, once upon a time I had graduated from college and went right into a corporate (has only been 2 years since). I was fortunate enough that I got assigned a project that was just starting, and even though I had no clue what was going on, I started doing whatever was assigned.
I initially worked in java and then finished all my tasks earlier than expected, so they switched me to another C++ project that builds on top of it.
Fast forward 2.5 years, I'm now the team lead of the CPP project and all my friends who were in the core team have left the company.
As usual, the reason behind it is shitty management. These mfs won't hire competent people and WILL ABSOLUTELY NOT retain the ones that are. I can feel it in my bones that it is time for me to leave, but fuck me if I understand what I am good at.
I have been able to handle all the tasks that they threw at me, be it java or c++ - just because I love logic and algorithms. I have been dabbling in ML and AI since 4-5 years now, but could never go into it full time.
Now I'm looking at the job postings and Jesus Christ these bitches do not understand what they want. I have to be expert in 34567389 technologies, mastering each of whom (by mastering I mean become proficient in) would need at least 6-8 months if not more, all with 82146867+ years of experience in them.
I don't know if I am supposed to learn on Java (so spring boot and stuff) or I'm supposed to do c++ or I'm gonna go with Python or should I learn web dev or database management or what.
I like all of these things, and would likely enjoy working in each of these, but for fucks sake my cv doesn't show this and most of the bitch ass recruiter portals keep putting my cv in the bin.
Yeah...
If you have read so far, here's a picture of a cat and a dog.

I shit you not. This this a job qualifications qualifications entry level on LinkedIn.

7+ years working as part of a development team and with the following technologies:
Node.js Typescript and Java-based, microservice-driven applications using Spring Boot or similar framework
RESTful API design / microservice architectures
MongoDB or any other NoSQL DB
Message queues e.g. RabbitMQ, Kafka etc.
Modern MV*(MVC, MVVM, etc..) frameworks e.g. React, Angular, Vue etc.
JavaScript and design patterns, CSS and HTML
Modern CSS and view libraries e.g. RxJS, Angular Material, Typescript, JS ES6 etc.
Unit and UI testing using third party tools e.g. Jest, Cucumber, Groovy & Spock, etc.
Bachelor's degree in computer science or related field

oh, it got better!

One year ago I got fed up with my daily chores at work and decided to build a robot that does them, and does them better and with higher accuracy than I could ever do (or either of my teammates). So I did it. And since it was my personal initiative, I wasn't given any spare time to work on it. So that leaves gaps between my BAU tasks and personal time after working hours.

Regardless, I spent countless hours building the thing. It's not very large, ~50k LoC, but for a single person with very little time, it's quite a project to make.

The result is a pure-Java slack-bot and a REST API that's utilized by the bot. The bot knows how to parse natural language, how to reply responses in human-friendly format and how to shout out errors in human-friendly manner. Also supports conversation contexts (e.g. asks for additional details if needed before starting some task), and some other bells and whistles. It's a pretty cool automaton with a human-friendly human-like UI.

A year goes by. Management decides that another team should take this project over. Well okay, they are the client, the code is technically theirs.

The team asks me to do the knowledge transfer. Sounds reasonable. Okay.. I'll do it. It's my baby, you are taking it over - sure, I'll teach you how to have fun with it.

Then they announce they will want to port this codebase to use an excessive, completely rudimentary framework (in this project) and hog of resources - Spring. I was startled... They have a perfectly running lightweight pure-java solution, suitable for lambdas (starts up in 0.3sec), having complete control over all the parts of the machinery. And they want to turn it into a clunky, slow monster, riddled with Reflection, limited by the framework, allowing (and often encouraging) bad coding practices.

When I asked "what problem does this codebase have that Spring is going to solve" they replied me with "none, it's just that we're more used to maintaining Spring projects"

sure... why not... My baby is too pretty and too powerful for you - make it disgusting first thing in the morning! You own it anyway..

Then I am asked to consult them on how is it best to make the port. How to destroy my perfectly isolated handlers and merge them into monstrous @Controller classes with shared contexts and stuff. So you not only want to kill my baby - you want me to advise you on how to do it best.

sure... why not...

I did what I was asked until they ran into classloader conflicts (Spring context has its own classloaders). A few months later the port is not yet complete - the Spring version does not boot up. And they accidentally mention that a demo is coming. They'll be demoing that degenerate abomination to the VP.
The port was far from ready, so they were going to use my original version. And once again they asked me "what do you think we should show in the demo?"

You took my baby. You want to mutilate it. You want me to advise on how to do that best. And now you want me to advise on "which angle would it be best to look at it".

I wasn't invited to the demo, but my colleagues were. After the demo they told me mgmt asked those devs "why are you porting it to Spring?" and they answered with "because Spring will open us lots of possibilities for maintenance and extension of this project"

That hurts.
I can take a lot. But man, that hurts.

I wonder what else have they planned for me...

Keeping my face straight as I ask them why are they asking me DS&A questions for a backend development job in which damn near everything will be taken care of by a package or a special config inside of something like spring boot or netcore and where damn near most of my requests will be of the form "can thou make tis button LARGER?"

Then watching their sad faces as I terminate the interview because I don't play those fucking games for web development jobs.

I miss old times rants...So i guess, here it goes mine:

Tomorrow is the day of the first demo to our client of a "forward-looking project" which is totally fucked up, because our "Technical Quality Assurance" - basically a developer from the '90-s, who gained the position by "he is a good guy from my last company where we worked together on sum old legacy project...".
He fucked up our marvellous, loose coupling, publish/subscribe microservice architecture, which was meant to replace an old, un-maintainable enormous monolitch app. Basically we have to replace some old-ass db stored functions.
Everyone was on our side, even the sysadmins were on our side, and he just walked in the conversation, and said: No, i don't like it, 'cause it's not clear how it would even work... Make it an RPC without loose coupling with the good-old common lib pattern, which made it now (it's the 4th 2 week/sprint, and it is a dependency hell). I could go on day and night about his "awesome ideas", and all the lovely e-mails and pull request comments... But back to business

So tomorrow is the demo. The client side project manager accidentally invited EVERYONE to this, even fucking CIO, legal department, all the designers... so yeah... pretty nice couple of swallowed company...

Today was a day, when my lead colleague just simply stayed home, to be more productive, our companys project manager had to work on other prjects, and can't help, and all the 3 other prject members were thinking it is important to interrupt me frequently...

I have to install our projects which is not even had a heart beat... not even on developer machines. Ok it is not a reeeeaaally big thing, but it is 6 MS from which 2 not even building because of tight coupling fucktard bitch..., But ok, i mean, i do my best, and make it work for the first time ever... I worked like 10 ours, just on the first fucking app to build, and deploy, run on the server, connect to db and rabbit mq... 10 FUCKING HOURS!!! (sorry, i mean) and it all was about 1, i mean ONE FUCKING LINE!

Let me explain: spring boot amqp with SSL was never tested before this time. I searched everything i could tought about, what could cause "Connection reset"... Yeah... not so helpful error message... I even have to "hack" into the demo server to test the keystore-truststore at localhost... and all the fucking configs, user names, urls, everything was correct... But one fucking line was missing...
EXCEPT ONE FUCKING LINE:
spring.rabbitmq.ssl.enabled=false # Whether to enable SSL support.

This little bitch took me 6 hours to figure out...so please guys, learn from my fault and check the spring boot appendix for default application properties, if everything is correct, but it is not working...

And of course, if you want SSL then ENABLE it...
spring.rabbitmq.ssl.enabled=true

BTW i really miss those old rants from angry devs, and i hope someone will smile on my fucking torture

They don't tell you this is in uni but your skill in merge conflict and circular dependency resolution is more essential in the real world than your knowledge of data structures.

Spring vs Spring Boot

Starting a new job tomorrow, old job was a software engineer working on mostly PHP with some mild Java stuff, tomorrow it is Java Spring Boot backend work. Should be an exciting change of pace

I work with J2EE every day, especially Spring and Spring Boot.
I like it very much but when I am home I love tinkering with C++ (even tough I am a beginner in this language).
Is anyone else like this? It's like C++ has a misterious charm for me, not sure why. I also enjoy haskell and erlang, but keep at getting back at C++.

You just realize the sheer amount of dependencies spring boot has, when maven tries to resolve them while sitting in a train with bad wifi

College Senior Thesis is done. Wrote the whole fucker as a Spring Boot Microserivce and my brain is fucking jello after 4 straight months of work.

I need something lightweight, I need something fun to code as I wind down at the end of the year.
I think I'll play around with Node.js and Typescript and learn about this docker thing people keep talking about before I go back to Java exception hell.

I'm not ready to be a Jr Dev next year. I'm too young to work this kind of job for the next 40 years.

> Wants to learn something new (pref not JavaScript)
> Can't find anything that's as dope as Spring boot (java framework).
> C# sucks
> Python ain't going anywhere
> PHP is dated
> Go sounds like a good choice but so damn non-useful if you don't do ultra concurrent stuff at google

Ends up getting more used to JavaScript
Suggestions? For summer learning... Freshman year.

FUCK.
NEXTJS.

...

THIS PIECE OF FUCKING SHIT WORKED 4 DAYS AGO.

I CHANGED ***NOTHING***.

4 DAYS LATER I START THE PROJECT AGAIN AND HALF THE STUFF BREAK. NOTHING FUCKING WORKS!!!!!!!

SOMETIMES IT WORKS SOMETIMES IT BREAKS

MESSAGES GET SENT SUCCESSFULLY 2-3 TIMES IN A ROW AND THEN Random 401 error

Random page glitch flickering when routing to new pages rendering the content blank

Random list map iteration crashes on ui dev side

This is such a fucking SHIT

Now i started my angular and spring boot exact same project that i stopped worjing on since october 2023 AND EVERYTHING WORKS FINE WITHOUT ANY RANDOM ERRORS

RANDOM ERRORS ONLY HAPPEN FOR NEXTJS FUCKSHIT FUCKING FRAMEWORK

FUCKIEST DOGSHIT GORILLACUM MAD FUCKIJNNGG RETARD FRAMEWORK FOR AUTISTICS I WASTED SO MUCH TIME LEARNING THIS PIECE OF FUCKING GARBAGE!!!!!!!!!

Javascript is cool.

But i have studied databases for a few weeks and i have been thrown into the backend.

Java - spring boot - myBatis - postgreSQL.

Its a big change to my react world.

And its fucking amazing.

How is coupling backend + frontend as a single nextjs app a good idea? What the fuck is this?

What if you have to create new replica sets of a backend because of high load pressure? What about load balancers?? What if i want my backend to be a microservice? How do i unit test the backend if its cluttered with frontend? WTF IS THIS

WHY DID NEXTJS THINK THIS IS A GOOD IDEA AND WHY DO SO MANY DEVS LOVE THIS IDEA AND GLORIFY NEXTJS?

Nextjs seems like the type of framework that was built by a frontend web developer who just refuses to learn backend technology at all costs.

---

its been a few hours and the concept of nextjs is bending my mind rn. I thought nextjs is just another frontend framework. A react killer. Only to find out its both a backend + frontend framework.

Cluttering backend stuff into frontend is gonna get messy no matter how much you try to modularize the code. Am i lost or am i right???

---

Scratching my head over nextjs. Looks like a great framework for small-mid project but definitely not large project. The more shit the project needs the more messy shit become. Angular has modularized all of this in separate folders -- components services guards interceptors (now new stuff coming called Signals) etc. All of it is separated in individual folders and kept frontend-only. Simple enough. No backend clutter

---

Can i even use nextjs strictly as a frontend framework while it uses my custom backend built in java spring boot? For example use nextjs /api/ folder to handle custom routes built outside of nextjs framework?

Am i insane here

Recruiter answered me

Rejected

They decided to choose another candidate because... [the reason will be announced at the end of this rant]

...

I was working on my project

I am learning new tech

And shitting 10 times a day from these jobs and recruiters, the usual me

HE the recruiter contacted me a few days ago

HE offered me nodejs position

I AM the one who was HONEST and told him i dont work in nodejs i work in java

HE then continued the conversation

HE offered me a java spring boot backend position

I AM the one who read the requirements

🔥🔥🔥
REQUIREMENTS: 3+ years of experience
🔥🔥🔥

I AM the one who told him i have 5+ years of java spring boot and 8+ years of java experience.

HE said great I'll contact the clients and let them know

TWO WEEKS LATER OF SILENCE

"unfortunately they chose some other candidate because they need someone with 10+ years of experience for this role"

---

Are you fuc

Fucking

Ki

Wasting my Fucking time?

You decide to slam into my peace and offer me a job position with ALL THE REQUIREMENTS I FULFILL, JUST TO RANDOMLY REJECT ME FOR AN INVALID FUCKING REASON?

If i said i had 10 years of experience

They would reject me because i dont have 15+

If i had 15+ years of experience i would get rejected for not having 30+

If i had 30+ years of experience fucking your whole family and bombing them to dust like in palestine till their bones die and worms eat your fucking down syndrome brains, they would say i need 160+ year of experience

Fyck you

Truly.
From the bottom

Of my fucking balls and cum

From my fucking dick

From my fucking shit and asshole

From my vomit

I wish you death.

I wish karma to kill all of their family members (the clients who rejected me) slowly one by one. Final destination accidents type of deaths. Truly i hope you and wish you the worst.

[Here the intro continues]

I will repeat again:
- REQUIREMENTS: 3+ years

I have:
- 8+ years

They rejected me because:
- I don't have 10+ years

I told all of this to recruiter now. Politely but because im losing my patience i was very very passive aggressive with my response. In the context of

1. I TRULY dont give a fuck for your rejection (which is the truth)

2. Your clients are low IQ dumb as fucking retards because they choose people based on the YEARS OF EXPERIENCE

3. Explained him: IF YOU ARE SO FUCKING STUPID TO UNDERSTAND THIS COMMON SENSE, I'LL EXPLAIN IT TO YOU: CHOOSING DEVS SOLELY BASED ON THE YEARS OF EXPERIENCE MEANS YOU ARE FUCKING STUPUD. There are devs with 2 years of experience who are WAY smarter better efficient and more knowledgeable than some devs with 5-7 OR MORE years of experience. Thats because some people progress better faster or more efficiently in 2 years while others need 5 years. Etc. You're fucking stupid as shit for this sole decision

4. Indirectly let him know that i am not pissed off for rejection. I am pissed off for my time being FUCKING WASTED.

5. Also pointed him out: your job description says its looking for a dev with 3+ years of experience i told you i have 8+ and you reject me because I don't have 10+. Are you Fucking stupid? Fuck you. Truly fuck off. Get the fuck off my dick and eat the shits i shit straight out of my asshole. I'll shit in your fucking mouth you fucking bitch. Your wife also probably fucks some other guys while you're at work and she doesnt respect you or love you. In the matter of fact give me your fucking wife/gf and I'll Fucking fuck her to death

To the clients once again: Truly i hope Hamas fires a missile at israel but misses and hits your fucking home and your whole fucking family blows up to atoms and particles. Completely erased from existence.

For all the hate that Java gets, this *not rant* is to appreciate the Spring Boot/Cloud & Netty for without them I would not be half as productive as I am at my job.

Just to highlight a few of these life savers:
- Spring security: many features but I will just mention robust authorization out of the box
- Netflix Feign & Hystrix: easy circuit breaking & fallback pattern.
- Spring Data: consistent data access patterns & out of the box functionality regardless of the data source: eg relational & document dbs, redis etc with managed offerings integrations as well. The abstraction here is something to marvel at.
- Spring Boot Actuator: Out of the box health checks that check all integrations: Db, Redis, Mail,Disk, RabbitMQ etc which are crucial for Kubernetes readiness/liveness health checks.
- Spring Cloud Stream: Another abstraction for the messaging layer that decouples application logic from the binder ie could be kafka, rabbitmq etc
- SpringFox Swagger - Fantastic swagger documentation integration that allows always up to date API docs via annotations that can be converted to a swagger.yml if need be.
- Last but not least - Netty: Implementing secure non-blocking network applications is not trivial. This framework has made it easier for us to implement a protocol server on top of UDP using Java & all the support that comes with Spring.

For these & many more am grateful for Java & the big big community of devs that love & support it.

How long does it take you guys to learn Node JS?

My professor wants me to work for him on a CRUD Server for a semester, I have some experience with JavaScript and API programming with Spring Boot. Should I take the offer and learn more about Node at home?

I think I will feel like an imposter if I take the offer if I don't have any previous experience in the stack

"Java and C++ Spring Boot and Angular Ansible Jenkins Azure Hosting"

nice, a stack for boomers lost in the 2000s

stop it. just stop it.

"Some other tech buzzwords we use"... yeah, "typescript" and "big query" are not "tech buzzwords" they're literally the names of languages and/or tools

tell me you're an HR rube without telling me you're an HR rube

😩😩😩 <- love this one, literally called "weary face"

Spring Frameworks and the projects surrounding it such as Spring Boot, Thymeleaf, and recently lombok. Without these API's and frameworks I wouldn't be using Java half as competently as I am.

Development is moving further and further towards containerization and it's a massive time saver.

When learning the Spring Framework where should I start?

!rant

For a bunch of application redesigns that we are doing at work I am letting the other two developers in my department help with selecting the stack. Normally, we work with Java and PHP, and while they seem to enjoy php I find them concerned at the possibility of making it more Java centric.

So I compiled a list of examples of different tech stacks that are not only more modern (cuz our Java stuff is old JSP stuff) but also simple to learn and use. Mind you, the point is to make this a gradual change, not just rewrite the entire house from scratch.

the list contained examples in:
Python: django and flask

Ruby: Ruby on Rails

Java: Spring Boot

Golang: Small self made mvc framework I built, nothing fancy on it, it uses templates and shit, didn't make it api centric

Node: Express examples in both vanilla JS and TypeScript

php with Laravel.

Since we work with php most of the time as well I imagined that they would be more inclined for Laravel, but I was wrong :P they seemed to like the Node Express route and the Golang route more than anything else with Python and Django being close.

Personally I know that there is more to selecting a stack, but initial perceptions make for a lot of things in selection of the stack.

Pretty excited, if they gauge everything considered in regards to what we have and we found Golang to be a clear winner it would give them the chance to add a nice and competitive tech to their resumes.

not a rant, or anything per se, just wanted to share some stuff with y'all

Spring Boot is the best that has happened to Java.

Eli5: senior dev here, 18 years experience in tech. I don’t get why spring boot/batch is so highly rated. I absolutely hate it. Please tell what I’m missing?

Tomorrow I go back to work. It was one beautiful week of vacation after years without having one (since 2012) and the next one is comming up in 3 weeks. Man cannot wait. Started a small Spring Boot project with Vue.js as the front end and have been having a vlast with it (see what I did there) after considering many stacks.

Went through Python flask, ror, php lumen, php codeigniter, mean, Meteor, Sails and finally settled on Spring :) the front end was a tad harder since I am better with React and Angular but wanted to try something different. Cant wait till I continue with this.

It's so frustrating when libraries just give you a hello world example and you have to figure out what the fuck it does. No comments, no nothing. Then you go read the documentation, and find out they have topics for everything, but nothing explaining how it all comes together. They give you a hello world and then you have to figure out how the damn thing works.
Now I have to watch YouTube tutorials which will probably all use fucking Spring Boot and extra libraries. I just wanted a barebones example, is that too fucking hard?

EDIT: maybe I should take a break from this thing

I'm trying to get a websocket connection in Java spring boot to work and I'm close to commiting suicide.

What would the world be without Javas famous AbstractSingletonProxyFactoryBean.createMainInterceptor() ?

Sealy though I am loving Java and Spring Boot

My workplace is still using xml based configuration, and non-spring boot projects.

So every spring boot tutorial I find feels like "Look at how easy you can get this running" and then it's just actually a toy you can't get into production.

Also it kind of bugs me that you need to be online to actually be able to initialize/create a spring boot project and every single tutorial says so.
You can make a local network m2 repository, but can one make a spring initializer service?

Either way, migrating every single project to Spring boot is a no-no,

And I'm stuck with like 5 prototypes of SSO integration from which only 2 work, and the other 3 have their own problems.

One does redirect to the login and all, but the SAML endpoint gets 404 on response when you log in.

One is on OpenID Connect, but I would need to update the project from Spring 3 to Spring 5 to get it working, which upon attempting to do seems to break everything else.

One has an external library handling the security context just the way we are accustomed to, but it only does a 401 forbidden when you go without logging in and I'm starting to think it is actually one of those that require you to extract the token or something manual like that, which wouldn't work for us

The other two are spring boot tutorials that worked out of the box, both SAML and OpenID, still can't use those for the main projects.

I'm tired of dealing with this configuration hell, been two months at this, I want to get features done as usual, not be stuck configuring stuff that might or might not work.

Rant aside, I think I figured I need to use a different Security adapter, but I needed to vent.

Building web applications with Java technologies

Was struggling with a NullPointerException that apeared on a test machine of a standalone spring boot app I'm developing...

5 hours latter I found the reason by accident....
The default session timeout was too low...
Increased that bitch to 10 hours and don't rely on session anymore to pass data...

Spring boot.

God, I hate you.

Spring boot does very much automagically.... but to find every possible configuration is hard....

I found out that it has an automatic config for Scheme Server... but how the fuck to configure it 😑

And do I still need avro made domain objects 🤔 it's hard to fight through all these documentations and versions of spring. 😖

This is really annoying when you’ve good paid job with really good coworkers but you want to change it... I always wanted to be a programmer but when I started my work in IT trade I got job as administrator... several years have passed and now changing my job is a big deal (degradation of my salary to 1/2 of actually). I don’t know what should I do... my programming skills is not impressive...I know java a bit with spring boot , hibernate and some other things(totally junior lvl of these skills)... but I think it’s not enough...this is really hard situation :/

Why are you paying me to architect your new stack if you're just going to mandate that I use Guice and Jersey "because that's what you're using already"? I'm sorry. You're wrong. Spring Boot is not a "dying technology". I'm not going to build you a servlet from scratch. Get fukt.

Okay... I am more than annoyed. 😵😵😵 I've been trying for days to get 2 small dockerized Spring REST-Services to communicate with each other. Without docker the services work fine with each other. I've tried many tutorials, examples, hints online and so on and none works or does something else. There is so much deprecated stuff or huge tutorials where I have to install 1000 other useless things. I kinda feel like this Microservice Stuff is a myth or I'm just stupid. Even my partner has no clue.

I now remember what I was supposed to do this weekend.... (Read a Spring boot book)

Too late now... Spent most of the weekend playing scrabble instead.... Not sure why though...

What is the use of Java nowadays besides Android? I rarely see Desktop apps written in Java and backends are developed more efficientl with django, node.js ,etc... just think about it setting up spring boot and all the warnings and errors...

I just learned Serverless.com

Thats it?

Shit was 100x more easy to learn compared to the brutality of terraform devops reactive streaming kafka rabbitmq sockets and other shits i had to fuck around and find out.

Dont even have to watch tutorials for this. Just building 1 simple crud project and read the docs was enough.

However after deploying these serverless shits to aws Lambda i noticed that it takes quite some time for the api to fetch response. Why?

On postman calling the route for the first time i have to wait like 3s for api to fetch all (with limit of 10) or create 1 dto object. Then every next api call is 100-150ms which is ok. But it could be better no? Locally my spring boot rest api takes 3-7ms of load time. Why is this 100-150ms?

Joined a startup, pretty happy with the company over-all so far truthfully. Secured a large project yesterday with higher billables so job security wise things are good. However... The project I've been working on is a mix of a Spring boot webapp and a game. Two separate applications that interact with each other.

Two teams. A home team, and an away team, plus.... 2 "AI's" to play against... Well.... whoever designed this "AI" designed it so they can only ever play as the away team. Why... every function, every method, every bit of logic is coded around what "Half" of the inning it is.... Now I had the bright idea of picking up the hardest task on the ticket list, of making these AI's be able to play as the home team.

WHAT A TASK, and to make things worse. Instead of using some kind of proper inheritance with actual structure, we have TWO COPY AND PASTED AIs where the other has more hard-coded team sided logic that needs to ALSO be adapted.

17 points my ass.

I do love my job though.

We have a full architecture deployed in a vm, and two teams works sharing it. All the apps were running as expected, the other team had demo and ask us not deploy anything in server....so we copy the war of our spring boot app to the server (23MB). Server collapse 10' before demo. We said that we weren't. I hate the other TL. I was happy.

I am working on spring boot jwt project. Ive encoutered a UserDetails class name.
Why is it named UserDetails?? Where the fuck are those details??!! COZ I CANT SEE THEM

Those kind of methods can be found also in other various Services for example LocationService or UserService but none of them is called by developers for example LocationDetailsService. WHAT THE FUCK. Wouldnt it be better to name it UserSecurity????

What's the difference between Spring Cloud and Boot? And what's a good book to learn either?

And I guess Spring as well. Is that a pre-req? I'm not familiar with much other than Bean and Context and not sure how AutoWired exactly works...

One project I have is to build an REST service but with subservices, and their replicas, handling different paths and on Openshift.

So these sub services need to be independently started but discoverable by the routing app(s).

Not sure how many layers but basically when a call hits the Router, depending on the path in the URL it sends the request to the appropriate subservices

I hate the fucking Spring WebFlux and the goddamn Project Reactor on which it depends!
Even debugging a simple CRUD microservice with simple business logic is such a pain in the ass, exception handling has a lot of "magic" implicit stuff which makes me waste hours in fucking trial & error and I have to use very little breakpoints because if a request is paused for more than few seconds it gets terminated.
I love functional programming but why shove it in fucking Java making me waste 90% of my time in trying to guessing what the fucking framework is doing, why not just use Scala which runs in the JVM? We don't even need compatibility with legacy code since it's a greenfield project!

And before you ask yes, I read a fucking book about Project Reactor and Java reactive programming and a lot of docs on Spring, Spring Boot and Spring Web Flux.

Nextjs is for script kiddies. This is such a fucking CHILDISH framework. The way you write queries is such fuzzy wuzzy BULLSHIT that u cant even write raw sql. Coming from hardcore java spring boot backend of 5 soon 6 years of experience i cannot believe how bullshit it is. Ill stick with java. I need to be oldschool. Im sick of this shit with constsnt new bullshit popping up sugar coated kiddie shit

wanted to do a poll for my team, Which should we use for development of spring-boot?
I personally recommend VSCode, what about you guys?

OAuth/Spring Security/Spring Boot
WAY over-complicated to implement.

How does Spring Boot/Data create a MongoClient/Template Bean to a **remote** database that requires password, certs, other configs?

These would be set in application properties but how does it get translated to the Beans?

I went through a lot of examples is like @Autowired MongoClient client

And then they just use it.

And I'm like wtf?

What the differences in performance between Django REST, expressjs, spring boot and Flask. What of these frameworks recommend for an API for quickly development and hosting with a $5 -$10 droplet.

In your opinion how much would it take to learn Java with /Spring(Boot)?/ enough to get paid for it?

I already know Java's basics and at uni did some frameworkless server side development.

In most businesses, self-proclaimed full-stack teams are usually more back-end leaning as historically the need to use JS more extensively has imposed itself on back-end-only teams (that used to handle some basic HTML/CSS/JS/bootstrap on the side). This is something I witnessed over the years in 4 projects.

Back-end developers looking for a good JS framework will inevitably land on the triad of Vue, React and Angular, elegant solutions for SPA's. These frameworks are way more permissive than traditional back-end MVC frameworks (Dotnet core, Symfony, Spring boot), meaning it is easy to get something that looks like it's working even when it is not "right" (=idiomatic, unit-testable, maintainable).

They then use components as if they were simple HTML elements injecting the initial state via attributes (props), skip event handling and immediately add state store libraries (Vuex, Redux). They aren't aware that updating a single prop in an object with 1000 keys passed as prop will be nefarious for rendering performance. They also read something about SSR and immediately add Next.js or Nuxt.js, a custom Node express.js proxy and npm install a ton of "ecosystem" modules like webpack loaders that will become abandonware in a year.

After 6 months you get: 3 basic forms with a few fields, regressions, 2MB of JS, missing basic a11y, unmaintainable translation files & business logic scattered across components, an "outdated" stack that logs 20 deprecation notices on npm install, a component library that is hard to unit-test, validate and update, completely vendor-& version locked in and hundreds of thousands of wasted dollars.

I empathize with the back-end devs: JS frameworks should not brand themselves as "simple" or "one-size-fits-all" solutions. They should not treat their audience as if it were fully aware and able to use concepts of composition, immutability, and custom "hooks" paired with the quirks of JS, and especially WHEN they are a good fit.

Today my manager asked me to provide technical skills. I replied with 'spring boot, react...(did not mention java)'.
He replied to me saying 'you know spring boot without java?'
Am I stupid thinking he should understand that already by seeing spring boot?

I want to learn Spring framework. A bit of research shows that spring boot allows me to skip all the painful xml configuration and generally makes life a bit easier. However, what if I have to maintain an old spring project in near future?

So,
a. Should I learn spring before spring boot
b. What is the best resource for the above?

The spring framework, it took a pain in the arse language {java} and turned into something reasonably good again! Props to Rod Johnson on that one

How to prepare for Microservices Spring Boot interview?

Question:

For a real time chat (web) app. Whats the best technology to use for this? I dont want the chats to have delays or glitches (in case it gets sent but not delivered etc).

Backend stack is java spring boot

How about kafka? Or rabbitmq? Or socket.io? Should i use redis? Should i use AWS SQS? Talking about cloud what AWS tools should i be using to handle this the best way?

Note: it must be scalable. Meaning if i wanted to extend this software more by building a mobile app (aside from web), i should be able to use the same backend easily

Note 2: it is not ONLY a chat app. Chatting is just 1 out of many functionalities. So chatting is not the main component of the project just a side thing

Keep in mind the backend is a microservice architecture etc. Database postgresql.

Can we all stop what we are doing and talk about the ridiculously long error messages in Spring Boot and how one can kill themselves scrolling for over 10hours to read the actual error?

Someone here on devrant told me

You cant learn everything. Its impossible. Instead you just have to learn how to learn

Now i got flashback to this several weeks later

And i begin to realize as i learn gitlab ci/cd (i only know github cicd so far)

Wondered

How would i integrate this cicd with spring boot java backend app?
Or angular?
Or nextjs?
Or nodejs?

Then I realized

I dont have to fucking learn all of that individually

Instead i can just learn how gitlab cicd works once

And then apply that same concept with slight modifications to whatever tech stack is in use

Does this make sense?

Is this how i should think while i learn new tech?

Is this the proper way of learning how to learn?

Sorry for my noob question. Too scared to post in stackoverflow.
I have a domain for my website from namecheap.my website is made with springboot and hosted on my homeserver port 80
I pointed my domain to publicip:80.never works fine except when i put my domain name in the address bar it redirected to my ip and shows the ip in the address bar.
Am I missing any steps?do i need to do something in my embedded tomcat server?

Cross post from /r/cscareerquestions

Hey guys how are you all doing!?
I got into university this September (Computer Engineering & Informatics).
Although I've been programming java since I was 14 (github.com/zarkopafilis), discussions with a friend who is a dot net guy and has been working full-time C# for 2 years now got me thinking.
Alright, Java's good. I've learned to love and hate the language. I also like Spring Boot and whole this ecosystem of stuff including Scala and the other Java based languages. Currently I'm in the proccess of completing some personal project of mine.
Alright, here's the big question: Assuming I am going to graduate (and start working) in 5-7-8 years (Masters, PhD - who knows), which language would you suggest I stick with and start learning? - for backend programming of course.
Don't tell me JavaScript. Although I don't like it I've digested the fact that I'll have to learn some of it for sure.
Currently that's what I'm thinking: Invest some more time learning how the JVM works (and probably keep improving my code quality). Also learn some more stuff regarding Spring Boot (and/or Web Services in general). Then advance onto Scala till couple of years pass. In that time I shall keep improving my SQL skills.
On the other hand I may start learning C# along with .NETcore .
Sidenote: Personally I prefer statically typed languages, that's why I dislike stuff like js and python although I occasionally find myself fiddling with small projects like some laser tracker written with python + opencv.
Sorry if this reads like a big disorganized dump of thoughts. Thanks in advance! :)

When im coding a backend in java spring boot i feel like im "at home" and in peace. No other programming language or framework makes me feel this way. Do you guys also feel like this when you work in your favorite language + framework?

I'm teaching a couple of classes where students (~18 years old) work on their own projects. I just deleted two of those from my machine: one Angular and one Spring Boot, but just boilerplate. Together, they were about 500 MB. I spent 2-3 hours working on a little Go tool to make concurrent HTTP requests and to report statistics on the response time. The entire repository is roughly 500 kB in size, but solves a genuine problem. My students have a bloat ratio of 1000 compared to me as a baseline, but my stuff actually does things. Today, I programmed prime factorization in PHP for some load tests (mod_php vs. PHP-FPM). The PHP script is 1148 bytes long (but the file system reports 4 kB). My students could learn more from such a script than from their overblown "projects", but "PHP sucks" I hearsay, so let's bloat on.

Architecture for Java REST API going to build/port from existing NodeJS one.
So Spring Boot + *

Lots of concurrent requests and large MongoDB calls. Current APIs use like 4GB memory for each instance because they don't use stream/pipe the response. Hold all data in memory and then return it all at once to user.

And well we expect more load in the future, so want to do this the right way.

So my understanding since this morning, is there's the blocking? MongoClient, (find* returns List) and now a Reactive MongoClient which is very async and like JS promises. Based on Pub, Sub model.

But the downside of JS promises was callback hell.

So actually 2 questions.
1. For each request, the db call done using the same MongoClient/db connection such that if there are 2 requests one would block the other?
2. Reactive Mongo would be non-blocking by design so would be better to support streamed responses?

My ex-colleague contacted me recently to help build a solution that would checkmate the case of code theft that they are currently challenged with. I tried to suggest the developers either work remotely (using rdp or similar), or physically with a company provided system. He rejected both recommendations and insisted the potential culprit shouldn't be aware he is being monitored

He proposed the following flow for what he intends I build: an obfuscated program scattered across the code base, possibly assembling at intervals or as a reaction to project build. Then signaling their server with details of the machine it's running on

The project to be rigged with the spyware is written in spring boot and I can't turn this down even if I don't think it's worth it cuz no work has been forthcoming and I'm nearly out of cash

So the question is, is the flow described above a feasible one? Can you suggest a smarter way to detect when the code is transferred to the system of an unaccredited engineer? Can you suggest any tips on how to go about this?

Is there any language or framework I am guaranteed to get a job in if I learn right now?

I know this is a shot in the dark cuz if such did exist, every job seeking entrant would simply flock to it; but I don't know how developers switch between stacks. Off the top of my head, recommendation but what if such social capital is missing?

Some background: I built and published a php framework called Suphle (angry-cray-9c191b.netlify.app), which surprisingly neither got any users after a year nor impressed any php employer to hire me despite hundreds of applications sent out

Rather than throwing in the towel, I wish to switch to some other software stack but I don't know where to start, If with all my proven php experience, I'm unable to land any php roles. I have tried searching for nestjs and spring boot internships or junior but nothing comes up. I have run out of time to study a language I will never profit from

I have a flutter app on playstore, built together with a product designer who worked on the ui cuz my front end chops aren't strong. I will preferably continue in a back end environment but if I can solicit immediate employment, I don't mind brushing up on any available tech, be it devops or what have you. I've also worked with spring in a professional capacity, although a very turbulent one where the team we had issues ranging ranging from absence of adequate docs for something as basic as authentication, to using nosql (totally unnecessary), trying to separate codebase into different projects to mirror the real life department (this was my idea). I don't know if it's Conway's law but I decided project should be split into admin, user and common modules/repos since they were being worked on by different devs and had little in common. Unfortunately, there is no doc for importing/sharing local projects so we had more days chucked off

Anyway, I Built a react native app a lifetime ago. Been around the block a bit and pretty confident I won't take much time to get up to speed with a tech. Where do I go or how do I start? I stay in Nigeria so may be limited from on-site roles as well

I started coding after getting into college and was overwhelmed with so many people around me who were already pretty good at it. Slowly I started learning things on my own, getting few internships to apply those skills and built few small projects. Managed to get a dev full time job, spent the last few months learning Spring MVC and Spring Boot. When I now look back, I definitely feel I've walked few miles, although there's still a lot to learn. I once doubted whether I can be any good in the dev world as my peers were bagging good jobs/internships but now it certainly feels that I can move ahead in this path which I liked so much. Yes, programming is stressful and painful sometimes. The learning curve is steep but if this is what excites you, go for it! Spend few months training yourself and then applying what you have learnt. Just, never give up! You can do wonders!
Oops, was I supposed to rant here? That is of course necessary. You can't imagine a dev life without rants but let that be for another post.

Recently attended an interview. The guy was some random company consultant. Job description was for spring-boot (also required templating engine experience). He was asking me whether I know angular and JEE (completely different and kinda opposite of the job desc). That's a bummer but good thing I've messed around with these once or twice so I know whatsup.

Also, who the fuck has already got 7 programmers and wants to double up to 14 by only adding university students to the team (after teaching them angular and jee for a month, but whatever, its only a fucking month), in order to complete a new project with tight deadlines?

I don't think I'm sticking with this one...

So glad I decided to use Spring Boot... Love it's bean configuration for dependency injections... Also love the RowMapper interface that's used with the JdbcTemplate. No more redundant Exception handling over and over again and I can still get close to the metal with writing my own queries. DOPE.

Hi guys so I have a fairly simple spring boot backend with mongodb. I am starting out with this setup for my app. I dint choose something like firebase because it will lock me into their ecosystem.

My question is can initially just run my backend with Digital ocean droplet or I need dedicated hosting?
Can it be done with docker. Is it the only way?
If not digital ocean then which one? Vultr, hetzner, linode, aws lightsail?
What are the things needed. Am I missing something?

!rant

Are there any worthwhile jobs were you (remotely) can code part time on the weekend. Want to make some money on top of my daily job.

Maybe it would also be possible to contribute in the afternoon (since my timezone is utc+2).

Languages of choices would be Java (preferly spring boot stuff) >> Python / JS. Any idea if that is possible?

Reworking old java apps. Holy shit im gratefull i can use spring boot.
But this code is handsdown awfull. Every file contains more ifs than other words. upto 6 layers deep. Thank god its at least properly commented.
But seriously how did this shit ever pass any QA. All legacy apps around here are a massive pile of if statements.

Spring Boot Admin is psychotic. Every time a client application registers to it, it barfs out random shit like: 1ear321fs31sfq.

I'm not sure who the fuck implemented the error handling of spring boot but goddamn he/she needs to be fired. Why the fuck does the application return a weird error about a setting not being set when it can't connect to a database?? Wtf took an hour to solve and that's not the only thing I hate about spring boot. Why is the documention utter garbage, why do I have to rely on tutorials and can't I just read in the documentation how for example the http rest mapping works. Now I have to cross-reference multiple tutorials to find the best way because guess what there are multiple ways to do something in this framework and some tutorials don't even work.

We were developing a new feature and on the code complete day, I had to take leave. While code review one of the devs changed my code without proper analysis.
End Result, half the things cannot be tested until that piece of code is fixed

Fucking hell of a Spring Boot 3 upgrade. Half the libraries aren't ready for the upgrade, nothing is document, the migration guides are trash and our internal supporting libraries are riddled with bugs.
Why did I get that godforsaken task?

Here can someone help me to guid become software architect. I work as lead in backend. My learning in spring boot , Python Flask and Djngo seems stagnated from a year or more. Want to go beyond but don’t know how.

Why do big enterprise companies like Java + Spring Boot as their backend?

spring or spring boot for begginer? I'd be grateful for some up-to-date tutorials because most of popular spring tutorials were released in ~2013-2015 and I think it may be obsolete a bit

Any word for feeling happy, stressed and accomplished all together at a time?
Story - Solved a major bug after digging into decompiled code stepping into each line for almost a day and half and later figuring that it requires just one line of change?

When there are multiple third party services getting used in your spring boot application. How do you manage their API creds.
Like I use Aws Secret Manager for the keys and different account level info. But after fetching in the application in runtime should we create classes to hold such info or just class variables are enough?
I'm more curious about the coding standard practices of different developers in the globe.

I got deployed to a client who uses Java. I have no knowledge in Java. Can I learn it in only half a month? Also including spring boot to create web services. The project will start soon.

They say the number 1 skill of a developer is the ability to learn fast. I'm a PHP JS guy by the way.

Thought I'd give kotlin spring boot a shot. I assumed it would work out of the box like with java. It didn't. Apparently with jdk 17 I chose an incompatible version with the gradle version provided. Downgrade gradle. 'runApplication()' still marked with an error, which I cannot seem to solve. Answers from the internet are no solution.
But I can run the project ... but I cannot reach my dummy address, same with maven ... wtf, which part of rtfm did I miss? Wasn't kotlin supposed to be the better java?

Why tf is Spring Boot so poorly documented?

Fucking stupid spring-boot-devtools dependency !!!

Started work at 11AM and was working on a Rest API system using Spring Boot. Got to know about Spring Boot dev tools and added it to my project.

Later in the evening my endpoints started throwing exceptions for no god damn reason. Invalidated the caches, restarted my IDE and laptop. Rolled back my code to almost vanilla branch !!! YET THE ENDPOINTS KEPT THROWING RANDOM EXCEPTIONS.

This went on till 1:30 AM (I live in a country where work-life balance is not a thing for software developers :)). Frustrated, the last thing I tried was to rollback the devtools dependency from my POM file. AND MY ENDPOINTS STARTED WORKING AGAIN 🤬

What the actual ffffuhkkk !!!!

To all those who contribute to spring-boot-devtools, you guys are doing a great job and it isn’t a personal attack towards you (I really mean it). It just messed up my project in some way and I was extremely frustrated.

Spring Boot

When Spring Security protects exactly the opposite of what you think you asked ... But you don't know why...

Can someone send me a guide article or tutorial how to build a chat app with kafka/redis in spring boot?

Should kafka or redis be used?

Or something else?

Also in a chat app should i store messages in postgres or not?

I cant find 1 fucking course or guide how to PROPERLY build a chat app

I was looking for a book on Microservices Architecture. There are several books, but I need one which explains all the patterns and related styles on design. The reason being is, I'm convinced about Microservices, but I need to convince my fellow teams and managers.

That feeling of pure fear when the spring-boot app is launching and the INFO lines are printed a bit too quickly at your taste and you expect dozens of stacktraces printed... while it's all good. It builded on the first try, congrats!

... Wait, why did it build on the first try?

Is there anyone who switched from Java backend (Spring Boot) to Nodejs? If yes what was your experience? Some people say it's a downgrade because of lower performance and less specialized tooling want do you think about that? Also what about salary? Is it the same level?

I don't get keycloak. Anyone who has experience with it, please help.

We have what I would think is a common setup: a kubernetes cluster with a Spring boot api-gateway and keycloak as oauth2-provider.

The api-gateway needs an issuer-uri to keycloak for endpoint discovery, i.e. to configure a bunch of endpoints to keykloak for different purposes.

The two main purposes are: 1. to redirect the user to keycloak (must be an url reachable from outside the cluster, i.e. ingress) 2. to authenticate tokens directly with keycloak from within the cluster.

Keycloak can be configured to set some of these discovery endpoints to different values. Specifically it makes a separation between backfacing (system calls in cluster) and frontfacing (user call from browser) urls All seems good.

However, when using this setup, each time spring security authenticates a token against keycloak it says the "issuer" is invalid. This is because the issuer is the host on which the token was generated. This host was the one in the url which the user was redirected to i.e. the ingress.

It feels like there is no way around this except running keycloak outside the Kubernetes cluster, but surely there must be a way to run keycloak in the same cluster. What else is the purpose of keycloak having the concept of back- and frontfacing urls?

Sophomore year starting soon so I'm looking for new project (s) to complete in parallel with the studies.
Some are more design-y and some more backend-y but I recently started getting better at designing so :)

1) Learn some fragment shader stuff. I've always been messing around with graphics and have a game on steam, so I think that's a good idea to be paired with signal processing.

2) Reactive web services. Preferably with spring-boot or vert.x but

3) I would also like to dive into golang (and make some reactive thing with it)

4) WebAssembly seems nice... But I got some concerns

5) exercise making wireframes -> CSS (with some js)

6) I've never really done any real backed work with nodejs, except serving and aot compiling js, or doing gulp tasks

7) Implementing a whole project, or a fraction of it as serverless on aws

* I'm definitely going to use a couple very simple services to make a docker swarm with load balancing, etc, just because I know how everything works but got no practical knowledge

8) Design an esports jersey for the university department I'm in (shouldn't take long)

So what do you guys think? Recommendations are welcome :)

#Suphle Rant 2: Michael's obduration

For the uninitiated, Suphle is a PHP framework I built. This is the 2nd installment in my rants on here about it.

Some backstory: A friend and I go back ~5 years. Let's call him Michael. He was CTO of the company we worked at. After his emigration, they seem to have taught him some new stack and he needed somewhere to practise it on. That stack was Spring Boot and Angular. He and his pals convinced product owner at our workplace to rebuild the project (after 2+ years of active development) from scratch using these new techs. One thing led to the other, and I left the place after some months.

Fast forward a year later, dude hits me up to broach an incoming gig he wants us to collab on. Asks where I'm at now, and I reply I took the time off to build Suphle. Told him it's done already and it contains features from Spring, Rust, Nest and Rails; basically, I fixed everything they claimed makes PHP nonviable for enterprise software, added features from those frameworks that would attract a neutral party. Dude didn't even give me audience. I only asked him to look at the repo's readme to see what it does. That's faster than reading the tests (since the docs are still in progress). He stopped responding.

He's only the second person who has contacted me for a gig since I left. Both former colleagues. Both think lowly of PHP, ended up losing my best shot at earning a nickel while away from employed labour. It definitely feels like shooting myself in the foot.

I should take up his offer, get some extra money to stay afloat until Suphle's release. But he's adamant I use Spring. Even though Laravel is the ghetto, I would grudgingly return to it than spend another part of my life fighting to get the most basic functionality up and running without a migraine in Spring. This is a framework without an official documentation. You either have to rely on baeldung or mushroom blogs. Then I have to put up with mongodb (or nosql, in short).

I want to build a project I'm confident and proud about delivering, one certified by automated tests for it, something with an architecture I've studied extensively before arriving at. Somewhere to apply all the research that was brainstormed before this iteration of Suphle was built.
I want autonomy, not to argue over things I'm sure about. He denied me this when we worked together. I may not mind swallowing them for the money, but a return to amateur mode in Spring is something I hope I never get to experience soon

So, I'm wondering: if his reaction reflects the general impression PHP has among developers globally, it means I've built a castle on a sinking ship. If someone who can vouch for me as a professional would prefer not to have anything to do with PHP despite my reassurance it'll be difficult to convince others within and beyond that there could be a more equipped alternative to their staple tool. Reminds me of the time the orchestra played to their deaths while the titanic sank

I want to study Java + Spring Boot but I hate the long syntaxes and boilerplate codes. Too many codes to do simple things turns me off.

I am an ASP.Net mvc web developer and now I need to learn the spring boot per new requirements. The books I am reading makes me to compare the spring boot with asp.net as the books mainly emphasize the spring "magic"

Any suggestions for the materials which put things in different way ?

Seems like spring boot kotlin doesn't want to cooperate in any way. Tried to set up a backend with it, but it keeps showing an error regarding wrong jvm-target. The project runs nevertheless. I changed the maven settings according to the docs, but no change. Whatever, still runs. However a newly created "hello world" rest endpoint just doesn't work, even following a beginner tutorial. localhost:8080/hello ... error fallback page.
I really wanted to give kotlin a try. Doing the same with java, instantly working.
Fuck spring boot kotlin. Or fuck me for not knowing how to handle it.

In Spring/Boot if you annotate a class as a Service is it started on a different thread? I used @PostConstruct to start listening to a connection.

The class with main () seems to just load Beans defined in the AppConfig?

I need it to start a thread that listens to a Mongo Changestream and trigger some action on each.

I noticed a log line under the watch() is never reached so seems it's blocking...

Undocumented thymeleaf secrets fuck you.

Its a templating engine

Trying to migrate an app from Dropwi Card to Spring Boot but can't get the YAML config read in correctly.

It's not reading the objects/lists/maps

Just treating each line as a key value.

Spring Boot says it sorts YAML configs and one seen some projects use this without issue.

But don't know how to turn it on.

Tried a lot of @*Config* all over the project but doesn't work.

Eventually just checked what Main.java loaded in the App context and well basically it never parsed it correctly...

Why tha fuck doesnt spring boot integrate with with eclips
why tha fuck do i need to run another instance of an editor

So I want to start with rest API development in Spring Boot. Where's a great place for 'all-you-need-to-know' related to Spring? I already built other REST API's so I just need a quick getting started and know how to organise,configure etc. my java project.

Bit of a stupid oopsie I had today that someone might appreciate.

We’re working on a microservice project in Spring Boot, running in a docker swarm. Past few days I get a Spring Cloud config server going in separate stack, create an overlay network, and get CI deployments to use the right profiles etc. It’s looking great, and the first component is working spectacularly.

Now just to do the other 6. Move config files to the Git repo, tweak CI, all the other faffing and hoohas; and deploy. Health checks keep failing, the containers are murdering themselves and resurrecting ad infinitum. They’re doing this so quickly that by the time I get the container ID to exec in and curl health, it’s no longer running. Cue frustration, increased caffeine and nicotine consumption; my sanity is slipping.

No errors in the logs, because from experience the Cloud Config errors ar at debug level. Whhhyyyy?? Some time later (way longer than it should have been) I realize I had never actually included the Spring Cloud Config starter. Boot 101, get your starter!
Since config client is just additional setup in properties.yml, there’s no issue of the dep isn’t there, it just doesn’t try to get the config.

The containers are still unhealthy, I can hear them screaming. But now at least it’s about something else...
