Back-end as a service for Real-time applications, based on a multi-layered micro-services stack

micromanager: "Quick and easy win! Please have this done in 2-3 days to start repairing your reputation"

ticket: "Scrap this gem, and implement your own external service wrapper using the new and vastly different Slack API!"

slack: "New API? Give me bearer tokens! Don't use that legacy url crap, wth"

prev dev: "Yeah idk what a bearer token is. Have the same url instead, and try writing it down so you don't forget it?"

Slack admin: "I can't give you access to the slack integration test app, even though it's for exactly this and three others have access already, including your (micro)manager."

Slack: "You can also <a>create a new slack app</a>!" -- link logs me into slack chat instead. After searching and finding a link elsewhere: doesn't let me.

Slack admin: "You want a new test slack app instead? Sure, build it the same as before so it isn't abuseable. No? Okay, plan a presentation for it and bring security along for a meeting on Friday and I'll think about it. I'm in some planning meetings until then."

This job is endless delays, plus getting yelled at over the endless delays.

At least I can start on the code while I wait. Can't test anything for at least a week, though. =/

I hate when idiots make assumptions without basis. My company so higher up idiots decided not to use Python. I said why they said it’s not scalable. I asked have anyone of you ever wrote micro service which can handle millions request every hours? Have you ever wrote service in Python? Have you ever worked on Python? Architect said but Python doesn’t have type support? I said there is use Python3. He said I want to validate my request payload. I told have you tried form and decorators. I told, I have 8 years experience. I worked in every language and I one has advantage over others depending on situation. Then they said, but we want only Java as finding resources is easy. I said have you checked git Python overtook Java in case resources, you are outdated. I don’t want to leave company but even after so many argument these idiots just dropping Python and because of that I am loosing so many good resources.

Interesting fact: Dogecoin is popular because of a Reddit bot that stole everyone's money.

DogeTipBot, a Reddit bot that was designed as a 3rd party resource for tipping Reddit users for good content was a bot that used Dogecoin as a micro-tipping service, giving many users their first crypto experience and popularizing the coin.

The creator of DogeTipBot went bankrupt, sold all of his coins, AND all of the coins of his users, and shut down the bot.

A currency born as a joke, made intentionally as backwards as possible, and popularized by a scam, is now worth $50 billion USD... now that's a meme.

When npm modules bring in 1500 micro dependencies for a service you could build in 15 minutes, it makes you wonder if you should, in fact, rebuild the wheel.

Inherited a simple marketplace website that matches job seekers and hospitals in healthcare. Typically, all you need for this sort of thing is a web server, a database with search

But the precious devs decided to go micro-services in a container and db per service fashion. They ended up with over 50 docker containers with 50ish databases. It was a nightmare to scale or maintain!

With 50 database for for a simple web application that clearly needs to share data, integration testing was impossible, data loss became common, very hard to pin down, debugging was a nightmare, and also dangerous to change a service’s schema as dependencies were all tangled up.

The obvious thing was to scale down the infrastructure, so we could scale up properly, in a resource driven manner, rather than following the trend.

We made plans, but the CTO seemed worried about yet another architectural changes, so he invested in more infrastructure services, kubernetes, zipkin, prometheus etc without any idea what problems those infra services would solve.

Another unrealistic deadline from our non-software developer PM.
He agreed to client upon delivery of a complete system consisting of 4 micro-services in Node and 4 front-end Angular application integrated with each micro-service accordingly.

Project Delivery date is December 31. I have told him It is impossible to deliver complete solution on December 31.
Now he wants me & my team to come to office even on weekends.
What an idiot !

Left a php job because I was fed up with php and was promised I could work with different languages.

Start new job, 2 weeks of work with a different language. A few days away from completing the micro service and it's been decided it's going to be deleted and I've been told I'm now to fix bugs in php.

Actually given up on life. Dont want to go in. Want to work at KFC. Had enough of being a php fixer :'(

Feel like the job I was sold now doesn't exist.

Do one thing... That's where the trouble starts.

Yeah. Architecture and separation, these are the foundation.

If you don't do these two in a proper and sane way, you most likely end up with the rotten pile of shit most companies call micro services.

Hot glued unmaintainable mess of deprecated shit stapled together by a custom framework abomination cause no one gave a flying fuck to properly design it.

I see these things daily.

I write the reminders every week.

"Hey, lil retarded dev, you don't need that dependency, you can just use languages feature XY added in version XY"

"But that's how I always did it"

Moments where you want to apply violence from the category "inhumane".

Or even more retarded: Yeah it does everything that was written in that one epic that took 6 months with 30 devs to finish.

I sometimes really wonder how some people managed to survive till they got the job. Parents must have been pretty vigilant 24/7...

In reply to atheist in another rant ;)

My tech debt meltdown is happening right now. We are releasing our huge micro service based product next week with no automated testing of any sort. Our front end clients are relatively DRY. No tests and dry = can't change anything = hacks on top of hacks.

Why? Team lead won't listen to me and has beaten me down so I don't care anymore. If it's broken fuck it.

Unpopular opinion: unit tests are often overrated.

Although a well written test suite is almost essential in some parts of the application (I.E. business logic) I cringe when I see hundreds or thousands of line which “mocks” everything to test a micro service which just does CRUD operations on a database, in cases like that unit tests are just a waste of time because almost every operation involves a mock which may not behave like the real database and often needs to be rewritten when the code undergoes a huge refactoring. In these case a integration test suite is faster to write and way more helpful.

Project manager: "What is a micro service? I'm dating a girl and she mentioned it and I want to impress her."

Me: "Well, you have monolithic services which tend to serve many different functions whereas a micro service tends to serve a single function or a few related functions. They are usually easier to scale and can be optimized to be faster. Still, right tool for the job."

Project manager: "Oh nice! So I can ask her 'Hey, want to see my micro service? It's quick and scalable.'"

-face palm-

He's leaving this week. I'm going to miss him though.

Seriously though, in that context, would scalability mean you're bringing friends?

So, I've been reading all this complaints about micro services which started to be loud thanks to the mad CEO of Twitter.
Keep reading but I am curious about your opinion as well

To me all the point of micro services has never been about improving the speed, in fact it might have a negative impact on the performances of an application. I think that given the calculation power we have nowdays, it's not a big deal

However on the other side, it makes all the rest so much easier.
When there's a problem on one service, I can just debug the given service without spending hours starting a huge slow turtle
If something goes down, it doesn't make unhealthy the whole app, and if I am lucky it's not gonna be a critical service (so very few people will be pissed).
I have documentation for each of them so it's easier to find what I am looking for.
If I have to work on that particular service, I don't have to go through thousands of tangled lines of code unrelated to each other but instead work on an isolated, one-purpose service.
Releasing takes minutes, not hours, and without risk of crashing everything.

So I understand the complaint about the fact that it's making the app run slower but all the rest is just making it easier.

Before biting my ass, I am not working at Twitter, I don't know the state of their application (which seems to be extremely complicated for an app deigned to post a bit of text and a few pictures), but in a company with skilled people, and a well designed architecture.

Everyone I tell this to, thinks it’s cutting edge, but I see it as a stitched together mess. Regardless:

A micro-service based application that stages machine learning tasks, and is meant to be deployed on 4+ machines. Running with two message queues at its heart and several workers, each worker configured to run optimally for either heavy cpu or gpu tasks.

The technology stack includes rabbitmq, Redis, Postgres, tensorflow, torch and the services are written in nodejs, lua and python. All packaged as a Kubernetes application.

Worked on this for 9 months now. I was the only constant on the project, and the architecture design has been basically re-engineered by myself. Since the last guy underestimated the ask.

So we're doing this contract work for this other company and the project is just an overcomplicated piece of garbage where they shoved every buzzword technology into it just because. I managed to get the code just about organized and functional on our side of the contract and it was looking up when suddenly the management decides "we had a rough start, lets start over, learning from our mistakes"
So I was thinking "cool, there were a lot of problems with this overcomplicated pre-optimized stack, surely we can only do better".. oh boy how naive I was. See Im not the guy in charge of the infrastructure (unfortunately) and really the project structure across this huge multi service project is a free-for-all kind of management.. so we had a call on friday where they explained how the new structure should be built... 3 new technologies, more micro services and even worse dependency tree later I was contemplating suicide on the spot.

I tried to make this shit usable and efficient and all my fucking work went down the drain in a single day of these fuckers throwing more buzzwords at the problem... I can't even get a new empty project started without browsing our huge 100+ repo project git for which dependency Im still missing to even run it...

I fucking hate this retarded piece of crap project and I hope every "manager" and "developer" with an exception of very few chokes on a cock...

So I was rejected by the management today for promotion to Senior 2 although I have done several major feature developments + infra design and basically end to end ownership.

Reason for no promotion? That's the best fucking part, according to the feedback, the work I performed on the service I created is well-designed,
and the code quality is commendable. However, they pointed out a notable difference in code quality between the micro-service
I built and the rest of the project developed by others. This, apparently, suggests that I lack a strong sense of ownership over the broader product.

First of all, we have super tight deadlines (almost 996), and I burned midnight oil to make sure the service I am in-charge of is designed really well.
Also, how in the flying fuck the other how the inability of others to maintain good code quality elsewhere in the product is being used as evidence against my sense of ownership
and initiative in ensuring high engineering quality for the repository I wasn't even working on

What a delusional management, the entire feedback feels like just an excuse to fuck off, we are not promoting you...
May be instead of doing actual engineering work, I should have just do minimal work and write more design docs / technical artifacts

It is very demoralizing after I worked hard for so many months, product went out really well.. yet when performance review comes, rejected with a petty reason

!rant

So I have bought a new laptop and this time instead of straight up booting linux I had an idea of giving micro$oft a try, so I have decided to use only their services for 2 weeks.

To be honest, I really did not expect windows to use do much cpu and hdd during updates and background tasks, but after a day it was ok and windows feels snappier than during my last encounrer (maybe cause the new hw?).

I was even so dedicated that I started to use cortana and I have to tell, that she is dumb as fuck, since she fails to understand even the basic tasks and if u want something advanced, she refers to the next update. But boy, tell her to open Visual Studio and she asks if you want VS Code or Visual Studio, which seems great. But my response was 'Code' then she insisted that I said Coke. Im like OK, Im not native english speaker, lets try Visual Studio Code, where she told me that there is no such thing and Spelling VS - Code ended me in bing search for Unesco :/

I really want to like Cortana, she has nice name, nice history, but she is like that A girl from class, who looks gorgeous, has great voice, but then u reallise that she just eats a book before exam and after that she is that dumb basic hoe.

I also gave a shot to Bing and Edge. Bing is something between Google and DuckDuckGo, since it gives you a liiitle less results from search history, yet if you want to find something in different language its even possible to tell you that what are you trying to find does not exist.

But I have to tell, that I like Edge and I mean it. Like... Its fast and has some good features, like pushing all your open tavs away, so you can open them Later. It also does not have that stupid ass feature that lets you control tab from left to right, not by chronological order, so you wont end up in infinity loop of 2 tabs. And even if people make fun of M$ trying to convince you to use Edge by being too aggresive. God go on edge and try to use some Google Service(You still dont use chrome?!).

I also tried to play with .Net core and I have to tell that against java they are a bit further. I liked some small features, but what I just simply loved was rhe fucking documentation. You basically dont need google, sincw they give you examples and explain in a human way.

What I didnt quite get was the 'big' Visual Studio. Tje dark theme to me feels strange(personal and irrelevant). Why the hell I do need to press 2 shortcuts to duplicate line?! Why is it so hard to find a plugin to give me back my coloured brackets and why the fuck it takes like a second to Cut one line of code on a damn i7?!

Visual studio Code was something different. It shows how dark theme should be done, the plugin market is full of stuff and the damn shortcuts are not made for octopi. So I have to recommend it ^^.

I even gave a shot to word and office as a whole and fuck I never knew that there are so many templates. It really made my life easier, since all you need to do is find the right one in the app, instead of browsing templates online, where half of them are for another version of your text editor.

Android Launcher was fast, had a clever widget of notes and the sync was pretty handy to be honest so I liked that one as well.

What made me furious was using the CLI. Godfucking damn what the fuck is ipconfig?! :/

Last thing what made me superbhappy was using stuff without wine and all of the addional shit. Especially using stuff like Afinity Designer and having good looking apps in general. I mean Open source has great tools l sometimes with better functionality. But I found out, that what is pleasure to look at, is pleasure to work with.

To Summarize a bit.

It wasnt that bad as I expected. I see where they are heading with building yet another ecosystem of It just works and that they are aiming at professionals once again.

So I would rate it 6/10, would be 7 if that shit was Posix compatible.

I know that for Balmer is a special place in hell... But with that new CEO, Microsoft at the end may make it to purgatory..

Betty: Opens slack chat with Bob, Tony and me to ask me to fix some data for a client who messed the setup. (Don’t worry just building a script that takes 3 hours to complete and that I must supervise)

Betty: Opens slack chat with Ron, Tim and me to ask me to force the system I made to ignore protocol because someone else’s fuck up made it so she didn’t get the output she expected.

Betty: proceeds to ask for status updates constantly on both chats. She also disguises them as her asking what she can do to “get it across faster” knowing there’s jack shit I or anyone can do to make it go “faster”.

Also Betty, vomits BS about my micro service being unstable in front of managers even though it is it’s correctness what brought to light a bug fucking up thousands of records silently.

Go fuck yourself Betty ☺️ and fuck the client

Got a nice solution, part of a micro-services system. Interfaces where they should be. Single responsibilities. Easily unit testable (and plenty of tests in there).
Then the Senior rewrites things because he didn’t see the point in having interfaces and couples every layer to a shared set of objects, and those objects are now shared by all the other micro-services too. One change in one and we have to repeat it in every service. 🤦‍♂️

I have already started the process of a side project by desiging the software, the architecture, the 3d model, ordered all the electronics of a pet 'smart' stable for my guinea pigs.

Which would automatically feed them and refill their water tanks silently but for me the point on playing around with dozens of sensors for like different water levels, water quality, hay, temperature, water quality (you get the point) ... Building a nice looking web interface or an App to control everything and get a live feed from different angles ( sounds a bit crazy altogether but it looked like a cool project )

I even started a instructable and had a github repo for sharing the source of the app/web interface and the whole micro service based server

I'm still at it and hopefully will start to build the ***ing wood and acrylic parts in the next month's but currently and for the last month's free time ist my archenemy

Keep you posted if you are interested 😀

Me: “I think I’ll check linkedin today”

Clicks on video: “... good perspective on growth and blockchain micro service apis that leverage ML models for understanding interfaces that welcome scalability within a agile environment...”

Me: *jumps out window*

Since the last update of the company antivirus some things became terribly slow, like IE dev tools, they are standard slow, but now they ere horribly slow, copying a 500MB file over the network to my pc now takes 10 minutes and the worst part is git. Git is unusably slow so i can't use git-tfs anymore and have to use standard TFS again.
And whenever all of this is happening there is always the same thing on the top spot of CPU usage 'trend micro unauthorized change prevention service'.
Oh how I hate that antivirus crap

Discovered this weak a breaking flaw in the micro-service pattern.

I don't have enough screens.

Anyone have books or blogs about microservices and APIs they like?

I spent so much time focusing on front end frameworks and technologies and now I'm having to teach myself RESTful API structures and micro service stuff. I should have spent more time on this earlier on...

Yesterday at 1:20 am, my first docker image build worked.

- I develop my software (a service in a micro-service architecture) in symfony
- I push it to bitbucket, CircleCI pull the code
- builds a new docker image
- Runs phpunit test using docker exec (lxc-exec, their docker exec doesn't work)
- If the test are successful, CircleCI push the image to hub.docker.com.

Took me hours to fix all the bugs and issues with this process. I feel so proud, yet soooooooooo tired fuck sakes.

I'll publish the template for everything,

- the Dockerfile for the perfect symfony2 image IMO (and I'll create a public symfony2 image)
- The circle.yml I used etc.

Give back to the community.

I love my job.

"We need our micro-service that we already use in two of our applications in the third. You can basically just copy all code from those"

*Spends 2 months trying to figure out (to) what (extend) the service actually does*

Some background:

About 2 months ago, my company wanted to build a micro service that will be used to integrate 3 of our products with external ticketing systems.

So, I was asked to take on this task. Design the service, ensure extendability and universality between our products (all have very different use cases, data models and their own sets of services).

Two weeks of meetings with multiple stakeholders and tech leads. Got the okay by 4-6 people. Built the thing with one other guy in a manner of a week. Stress tested it against one ticketing service that is used in a product my team is developing.

Everyone is happy.

Fast forward to last Thursday night.

“Email from human X”: hey, I extended the shared micro service for ticketing to add support for one of clients ghetto ticketing systems. Review my PR please. P.S. release date is Monday and I am on a personal day on Friday.

I’m thinking. Cool I know this guy. He helped me design this API. He must’ve done good. . . *looks at code* . . . work..... it’s due... Monday? Huh? Personal day? Huh?

So not to shit on the day. He did add much needed support for bear tokens and generalized some of the environment variables. Cleaned up some code. But.... big no no no...

The original code was written with a factory pattern in mind. The solution is supposed to handle communication to multiple 3rd parties, but using the same interfaces.

What did this guy do wrong? Well other than the fact that he basically put me in a spot where if I reject his code, it will look like I’m blocking progress on his code...

His “implementation” is literally copy-paste the entire class. Add 3 be urls to his specific implementation of the API.

Now we have

POST /ticket
PUT /ticket
POST /ticket-scripted
PUT /ticket-scripted
POST /callback

The latter 3 are his additions... only the last one should have been added in reality... why not just add a type to the payload of the post/put? Is he expecting us to write new endpoints for every damn integration? At this rate we might as well not have this component...

But seriously this cheeses me... especially since Monday is my day off! So not only do I have to reject this code. I also have to have a call now with him on my fucking day off!!!!

Arghhhhhh

What HTTP Header should be used to send an App identifier to a REST/micro-service

I remember reading about this a long time ago and want to suggest it again to my boss so it's easier to identify what specific apps making calls to our APIs

Learning how to build micro services using Spring Cloud. As I'm not familiar with this architecture, the company's lead engineer suggested me to do research & development on it, recommended me to follow official guide lines before involving me to the current under development project.

What's your advice regarding - what to keep in mind while learning micro service architecture (could be in one sentence)? It will be helpful to me. ^_^ Thank you.

My last post entails how my company moved me to a freelancing role upon completion of my task (VoIP micro service: incoming and outgoing calls, voice mail drop, voice mail greeting, call forwarding, sms, and a couple more features) — app is now live and used by company’s agents to contact leads on our other products (designing), so boss tells HR to tell me (I realized this from HR’s slack screen when on huddle with me) to add WhatsApp integration. I responded that since I’m a freelancer I would charge $30/hour for it. HR said he’d get back to me and it’s been 3 working days now.

They are also trying to have the app on Apps*mo so they cash out for other companies to use the app.

It’s been 2 weeks and a day since the end of my probation (I’ve been with them for 3 months) and no one has acknowledged this — I also wrote to my boss asking why management won’t acknowledge this but three days after probation they changed my role. Same company that held off my offer later to two months later in the job to offer a Senior Python Developer role as “HR has Covid and could not send it until now”.

He has not responded to my message. Pretty much no salary for me these past few days.

I’m now looking for other jobs. Meanwhile, I’m building from scratch AGAIN a VoIP micro service and I plan on making it public and free upon completion.

BUT I feel the company might take action against me. Do note that I did not sign the offer letter as the link had 3 days expiration and HR said he would send a new one but never did, even after I reminded him at least 2 days in a week.

While typing this, I got the urge to proceed regardless any circumstance.

Time to unwind after more than a week of building the structure of a micro service. I feel exhausted right now 😫😫

Monolith oriented micro service.
All the coupling and evolving resistance without the simplicity or consistency...
