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?

A lot of engineering fads go in circle.

Architecture in the 80s: Mainframe and clients.

Architecture in the 90s: Software systems connected by an ESB.

Architecture in the 2000s: Big central service and everyone connects to it for everything

Architecture in the 2010s: Decentralized microservices that communicate with queues.

Current: RabbitMQ and Kafka.

... Can't we just go back to the 90s?

I hate fads.
I hate when I have to get some data, and it's scattered on 20 different servers, and to load a fucking account page, a convoluted network of 40 apps have to be activated, some in PHP, others in JS, others on Java, that are developed by different teams, connected to different tiny ass DBs, all on huge clusters of tiny ass virtual machines that get 30% load at peak hours, 90% of which comes from serializing and parsing messages. 40 people maintaining this nightmare, that could've been just 7 people making a small monolithic system that easily handles this workload on a 4-core server with 32GB of RAM.
Tripple it, put it behind a load balancer, proper DB replication (use fucking CockroachDB if you really want survivability), and you've got zero downtime at a fraction of the cost.

Just because something's cool now, doesn't mean that everybody has to blindly follow it for fucks sake!

Same rant goes for functional vs OOP and all that crap. Going blindly with any of these is just a stupid fad, and the main reason why companies need refactoring of legacy code.

everyone around is hyped about new tech they get to use, new toys to tinker with, I can see their eyes shining when they hear "let's try and introduce kafka" - they would wiggle their tails all day long if they had ones!

And me? Well, a new potential employer got me so excited I couldn't wash a smile off my face for a few days! You know what they said? "we don't use any frameworks, we focus on clean code, solid, kiss and we write with tdd". Bare java - that's the best position I've heard of in years!

I guess I'm oldschool. But I truly believe their approach is the right one. Not trashing the code with spring [which is turning into smth what systemd is for linux/unix], hibernate and what not.

Just good old java code. Db, multithreading, request-mapping -- all plain, manual and simple.

Amazing!

just happend to me today

A 2d simulation of the mars rover curiosity and its commandControl station. Pure java. The two components talk to each other via apache-kafka. Rover has its own operating system (kernel) and resource management. Hooked up some sensors to NASA API.

In a time where a web dev is expected to know, well.. everything... Backend -JAVA, python, nodejs and C++ would be great.
Front- angular, react, other 10 libs
DBs -sql, mongo, redis, elastic, kafka, rebbitmq
Also be devops on the side with AWS and docker kubernetis and more stuff

How the f is that possible?

In my real job for the last couple of years and different companies, I usually use 1 language/framework & 1 main DB.. and although it's possible in some companies, but in mine, ppl dont get access to AWS etc..

So let's say there's me.. a server side dev for years.
So I decide to be better and learn Golang.. cool lang, never needed in my job, after few days of not using it I forgot all I learned and that was it.

Then I realized I gotta know some frontend cause everyone want a fullstack ninja nowadays.. so I tried Vuejs.. it was amazing .. never got to use it at work, cause i was a backend, and we didnt use frameworks on our products back then..
Also forgotten.

Then I decided to learned nodejs, because this is the coolest thing ever.. hated it, but whatever... Never got to use it at work, cause everything was written in other lang which the whole team knew... Forgot the little i knew.

Then I decided, its time to see what Angular is, cause everyone started using it... similar idea to vuejs which i barely remembered, but wow it's a lot of code to remember, or I'll have to google everything.. so I went over it, but can't say i even learned it.

Now Im trying to move on to python, which, I really am learning in depth.. however, since I dont have real experience with it, no one gives me a shot at being a python dev, so again i feel like I'm trying to memorize syntax and wasting my time..

Tired of seeing React in all job ads, i decided to have a look what's that all about.. and whadoyaknow... It's fucking the same idea as vue/angular with again different syntax..

THIS IS CRAZY!

in how many syntaxes do i need to know how to make a fucking crud api, and a page with same fucking post form, TO BE A GOOD PROGRAMMER?!?

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 many sh*t days does it need to make me down?
3 ...

I hate my company, for making everything overcomplicated and annoying.... I have to discuss with 3 peoples for 3 days to getting some gitlab premium licenses (20$ per month for 10 licenses)... Why do you need it? Why we can't use the free version? Why Why Why... It's not enough to tell them it will save us much times and improves the quality of development.....

Also I wanted to ask if we can to Jaxb or another Dev Conference this year... Then I got the information that we have about 2000 Euro for 10 people for training.......... What should we do if everyone buys a book this budget is out .... f*ck company....

Second day, half of the day was taken for fixing the live db on the fly cause of a bad structure of tables... at least fixed some other inconsistence too... later the day fixed a freaking shitty bug with Spring Devtools and 2 Classloader to make the product that I'm presenting in 2 days running.

Today next shitty day with discussion that everything I did last half year (introducing Microservices, Kubernetes, Kafka and other DevOps things) could be maybe useless when the external company will say that they use another ecosystem -..- for their microservices...

Someone looking for a disappointed java developer? I just want to develop the best product ever... I'm happy with every area... Frontend, Backend, DevOps, Fullstack, Architect in some kinds depends on the wishes and technologies.

Is just me or being a developer has become a complete nightmare?
I mean, I never expected when I got into it to have a simple life in the first place, it's a fucking problems solving job.
But heck, I'm in the field from more than 12 years and something has definitely changed for the worse. Believe me I am just seeking for a general consensus not approval or anything, but it doesn't feel anything like 10 years ago.

I have worked with .NET mostly in all his sauces from aspx, wpf, up to today .NET 10 and C#13 and in the meanwhile it happened that I needed to do tech assistance, code in exoteric shit, use arduinos and raspberries, use perl, java, turn into full stack with databases, devops and shit.

Each year it's worse, the "developer" word gets more and more blurred word to say "the one who must know everything".
I'm asked to know docker, kubernetes, kafka, CI/CD and devop shit, web dev, to get ertifications, to learn how AI works to the level of learning again matht to do matrix interpolations, to get on data science, python, numpy, pandas, pytorch and shit, to know every OS, to know about networking because APIs now have to use rest, a single verb for every action, because if routers and new communication protocols break you have to know and figure out why.

Not to mention that marketing and sales guy shove up the big customers ass every new tecnology to make our work look like bling-a-ling top notch 1% developer stuff that always use latest bleeding edge technology and you're forced to learn new immature frameworks every 2 months or so (latest being various javascript/typescript diagramming libraries).

Every idiot feels entitled to puke out a new framework or supersets of existing languages. I lost count how many supersets css has that I had to peek and learn lol.

Every fucking simple software I did from scratch and designed by myself, web portals for big pharma were much simple than whatever PM i get assigned to are and guess what, I published it and fixed ofc some bugs, but most bugs are related to customer unstable datasets and well, I never had bugs after the first few weeks, except once every few months and nothing serious.

The fucking things they let me do now are hypercomplicated and I spend days fixing other people bugs and we get some hair pulling structural problems becuase they shove in all they can (mediator patterns are a must): kafka, docker, messagebus, whatever javascript clusterfuck they can, patchworks of html and css blurred out in layers of hierarchical scss or sass, slapped into angular (the most immature and crappy shit in js) that has all of his hidden ways to bury and hide DOM (ng-deep: anyone? :host anyone?).

And it's all like this. Whenever I put hands everyone wants to do his little frankeinstein experiment cooking togheter in a cauldron a shit ton of different stuff, overcomplicated patterns.

it's a challenge at shooting flies with bazookas.

I'm really tired of technology at all, not only for my jobs. This fucking trend is a plague spread everywhere and now, since everyone has to deal with it, everything is unstable.

In my daily usage of a smartphone app crashes a lot or have weird troubles, slowness, websites are pretending to be full blown app with this shitty SPA trend and are filled with bugs and incompatibilites.

Basically every tech tool we use is 100% more prone to bugs than 10 years ago.I'm really thinking to find a simple job like baker or shit and get an old phone that just can call and send SMS.
I need to get out of tech for a few years to get back my sanity.

This is not a problem-solving job anymore.
10 years ago I needed to study too but once I got the tools in my hands the job was fun, you got a magic wrench and sky was the limit.

Now you got to fucking learn a ton of bullshit everyday and it's not like you see a end on it, everyday people push out new unstable and bugged shit waiting for devs to be guinea pigs for them. You gotta learn a ton of stuff of which 3/4 will be useless/obsolete/broken and considered inefficient the next month.

jeeeeeez

Scala is as horrible as Java. Been using Java at uni and once having discovered the simplicity and beauty of other languages (Python, golang), never went back.

Currently trying some apache projects (kafka streams, apache flink) where Scala is native. Same crap as Java. Needs 10x lines to write the same thing, abstraction over abstraction, and intuitive = 0. Why tf did it even got invented?

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.

Originally I'm coming from Java , about 2 years ago, I switched Node with TypeScript and had a hard time getting accustomed to Promises. It was a big relief when I learned about async/await. Much cleaner code, no brainfuck anymore when thinking about how to handle stuff that requires multiple async values and so on.

Now I'm working on a clients project as a Java dev again. SOA, Spring Framework, Kafka and MongoDB, nothing too complicated... if they wouldn't use reactor to bring reactive functionalities to Java.

It feels like I'm back in Promise Hell...

I am using python scripts for mathematical computations and deep learning wheres spring to build the server and now want to handle the scripts from spring guess what scripts were in python 3.6 and fucking jython does not support it.. so tried finding the different libs like jpy , jpe and analysisRPC.. Everything seems just bullshit .
Finally using Kafka to have my interprocess communication..

The day I'm fucking around with Kafka Streams API and had to work with Java after swearing it off 5 years ago for JS bae...

Is the day that Apache's everything is down. Can't even hit their fucking website. I just want a fat jar. Just one.

My team is currently using a confluent cloud kafka architecture via protobuf and wordpress as website.
We realized this is quite impractical when you want login functionality and such and would like to make a page from scratch now.
problem is we are all java backend developers with minor php knowledge, and php doesnt work well with protobuf or kafka.
how would you get such a website started. what language and frameworks are easy to get going?
