Nobody:

Senior frontend Dev at my company: "microservices best thing ever"

Also him: "Relational databases gonna die"

Also him (talking to the DB team): "You're gonna dissapear, Mongo is the future"

Me: "Eh... Dude, Mongo is still a database.."

Him: "Microservices"

Send help...

I have some databases on my new socks

Him: Relation databases are stupid; SQL injections, complex relationships, redundant syntax and so much more!

Me: so what should we use instead? Mongo, redis, some other fancy new db?

Him: no, I have this class in Java, it loads all the data into memory and handles transfers with http.

Me: ...... Bye!

So last semester, my college made a class compulsory to attend.
We were taught, "How to install MongoDB on Windows"...
With screenshots, not even live installation.

I wanted to die.. So much.. 😖

Forgot to secure my mongo db instance, found half the data gone, and a new db holding me at ransom , learn_how_to_recover_your_data , good thing offline backups are a thing.

Recovered in no time, never will I ever repeat this mistake

in my native language.

mongo = "expensive"

Mongo DB

😂

So here's is the thing.
For some weird reason I decided to work at a VC funded startup. For 15k year,(I live in a really poor country).

So, let me describe the hell I'm in now, and if for some good grace you happen to be hiring, please consider saving me from the horror that's ahead.

Company got funded 5 months ago, main owners are, an economist and a civil engineer with no programming habilities whatsoever.

They took 1 month to assemble "a killer team", with no hiring expertise they handpicked a CTO that came in 1 month later and took a month of vacation in his first month of work.

He didn't do any specification of the system that needs to be built.

The 2 naive owners hired the rest of this "killer team".

The team is good, but have no appreciation of planning.

They've built and rebuilt the backend system twice, once in graphql and the second with plain http (is not real rest, just a http api), in front of, guess what a mongo database.

This mongo DB is not only one, but 7, because we have 7 microservices, and each has its own database.

After some time, they decided to fire their CTO, and hire one more programmer(that's me), because the CTO wasn't doing anything.

The app has 3 parts, the app per se, a business version, and a help desk, guess what the helpdesk just appeared last week on the radar.

Long story short, we have one month to deliver what couldn't be built in 5.

When I decided to work for these people, I did not imagine the kind of clusterfuck that I was getting into.

It took me 1 month to realize the whole situation, now, I really would like to see some help from the deities of any religion, not for the project, that project is doomed.

It's how I'll pay the bills after that clusterfuck collapses that worries me.

Now in the startup no one is talking about how stupid the whole situation is. Or how far back we are. And at this point there's very little that could be done about it, I have a feeling that it could still be accomplished, but it's fading day after day.

I will do my best to live the best of this experience, and do as the musicians in the Titanic and keep playing the music even after knowing the Titanic is sinking.

I quit this startup side job coz I was over worked and under paid for 3 years and I decided it wasn't worth the mental fatigue and anxiety. Plus I didn't feel like it added any value to my life other than stress. Gave them at least 2 months notice (since February effective April 30th) coz as the only server side engineer+team lead, I did ALOT. Now they brought this hot shot new CTO who wants me to basically rewrite the entire app before I go while maintaining the existing system and making sure everything functions smoothly (there is a ton I chose to optimise to make things easier for the new dev who they have not hired and I have 4 weeks to go) . The app was built in mongo db now he wants it in mysql. Can't believe ask me this after breaking my neck and falling in and out if depression for this job?!! I want to laugh and scream at the same time.

Sometimes I don't know if my co-worker is that stupid or...
Well, he came to me with an strange problem with mongoose.
I looked at the error message. And guess what the database was not reachable. Asked him, did you check the mongo db service. No. Of course the service was not running. Told him to restart it. Then he restarted robo t not the service itself. Major face palm. He then asked me if I knew why his service was not running. Do I look like some kind of wizard? Told him to check the logs. Long story short, his drive ran out of space....

I was talking to a friend about the current state of machine learning through tensorflow and commented about the use of Javascript as a language.

He discarded the idea as he views Javascript as something that should only be used as a frontend technology rather than something to build backends or deep learning models.

I am thorn. I have always liked Javascript but will admit that I have used it mostly in the area of front end with very few backend instances(i did create a full stack intranet app in Express once, major success for the application it was hosting, it was a very basic api which had its own nosql db with no need to interact with the company's relational data, it was perfect for the occasion and still help maintaining it from time to time)

My boi states that node's biggest issue has always been npm and the quality of packages. I always contradict those statements by saying that if one uses community standards and the best packages then one does not need to worry about the quality(i.e mongoose over some unmaintained mongo wrapper etc)

I sometimes catch myself finding that my way of thinking adapts better to JS than it even does Python (which is his preference for deep learning) and whilst there are some beastly packages for python in terms of quality and usefulness such as matplotlib etc that one can do great things with the equivalent JS.

I mean, tensorflow.js came from the same wizards that did tensorflow (obviously) and i find the functional approach of JS to be more on par with how we develop solutions.

I am no deep learning expert, and sadly I have no professional experience with machine learning. But I venture to say that we should not cast aside the great strides that the JS community has done to the language in terms of evolution and tooling. Today's Js is not your grandaddy's Js and thinking that the language is crippled because of early iterations of the language would be severely biased.

What do you guys(maybe someone with professional experience) think of Js as a language for machine learning?

Do you think the language poses something worth considering in terms of tooling and power for ml?

The application that was working fine on local host failed to do one task which is to read users data from excel and save it on mongo db, in some collection document's embedded document. My last night and today morning was tensed due to this. So I decided to re deploy the same application on another instance that I have. Worked completely fine
😐😐😐

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?!?

Boss: Write a program to generate a report using some data from an existing one.
Me: OK, I will look into doing a POC
Boss: Also it would be stored in Mongo so all the data is queryable
Me: OK I will generate the file first
Boss: But it needs to be in DB, couldn't you just upload it when done?

This discussion goes on for 30 mins+ preventing me from finishing release related work...

IF THE FCKING POC/REPORT ITSELF IS WRONG OR IS MISSING INFORMATION/CAN'T BE GENERATED WHY THE FUCK DOES WHERE IT'S STORED MATTER?!!!!!!!!!!! WHY ARE TOY EATING TIME ON THESE TINY DETAILS THAT DON'T MATTER AT THE MOMENT.

FUCKING GET YOUR PRIORITIES STRAIGHT. YES EVERYTHING IS DOABLE... JUST NOT NOW.....

There's very little good use cases for mongo, change my mind.

Prototyping maybe? Rails can prototype, create/update/destroy db schemas really quickly anyways.

If you're doing a web app, there's tons of libs that let you have a store in your app, even a fake mongo on the browser.

Are the reads fast? When I need that, use with redis.

Can it be an actual replacement for an app's db? No. Safety mechanisms that relational dbs have are pretty much must haves for a production level app.
Data type checks, null checks, foreign key checks, query checks.
All this robustness, this safety is something critical to maintain the data of an app sane.

Screw ups in the app layer affecting the data are a lot less visible and don't get noticed immediately (things like this can happen with relational dbs but are a lot less likely)

Let's not even get into mutating structures. Once you pick a structure with mongo, you're pretty much set.
Redoing a structure is manual, and you better have checks afterwards.

But at the same time, this is kind of a pro for mongo, since if there's variable data, as in some fields that are not always present, you don't need to create column for them, they just go into the data.

But you can have json columns in postgres too!

Is it easier to migrate than relational dbs? yes, but docker makes everything easy also.

1. Learn Vue.js
2. Learn some backend framework or language like Express.js or ROR
3.Learn Mongo DB
4. Make a progressive web app
5. ???
6.profit?

So I have a friend. One of few who I can freely speak with using my natural language (so that means, narrow down topics to IT, mix some of my native language, mix in lot of english and mixture of our favourite languages terms (don't ask me how it works, but it works brilantly and its actually easier to communicate)). And its true friend, seriously.

But when we meet, 80% of time we spent together, every, single, fucking time we argue (in cultural maner, its more of discussion) about what enviroment and what languages have advantages against others. And it pisses the fucking hell out of me, when he takes his enviroment, takes his problems with exac his enviroment, and applies his favourite solutions to it, and goes on how they are fucking awesome and brilliant, and than I reply, sure in my enviroment if I ever had XYZ problem, I wouldn't say use mongo DB becouse I can do it my way, and it would work well too, but it's not really the way I really should solve XYZ problem, becouse in my enviroment you dont have it in the first place. And he will fucking go on, but at least he understands my solutions and finds various details where HIS solution works better. His solution to his problem vs my solution to non-existant problem.

But that's actually an example of much grander thing that I want to rant about. You see, that's not all that bad, we keep it civil and we somewhat enjoy these discussions even if often times, they are pointless. It's like playing games and shit like that, so it's not the point, I just used the example to make it clear what I mean later down the line.

So, to the actual point. What the living fucking fuck is wrong with people, for living fucks sake they cannot physically, mentaly, virtually or otherwise change mindset and point of view if they are telling YOU what to fucking do, what's better to do, etc.
What the fuck! You have around 0.1% of context that is in my head, and my solution works with most of it and your bearly manages to deal with your given 0.1%, so kindly please for living hell, fuck off telling me what to do, what is better in my fucking situation etc. You don't know most of shit I know about my own situation (dosent apply to people with coma and heavy mental issues, sorry its not 100% universal) that I know, yet you have something in your brain that fucking allows you (dosent tell you "its no-go lol") to try push thru your shit to me like it was your fucking life. It's not.

And to be clear, before someone gets sad becouse I was to broad and generic. If you giving advice you can do it properly. And there are people who legit have mindset "well, if I was you and known what you told me, I would do XYZ", but for what the living fuck reason most of people I know have more mindset of "Do XYZ coz fuck you if you dont, coz dat is my opinion and shit and I dont give a living fuck if it does what you want"

So what is the best free Mongo DB client for Mac? What are you using aside from the command line?

I prefer good ui and features. Thanks! 👍

What is a normal write speed (docs/second) for mongo db?

Can't find a benchmark online and well I'm trying to prove my point to my boss that our speeds are insanely slow due to index bloat,..

My one of my favorite open source project was Re-think DB!

It was highly light weight real-time DB.
One fine day, I read a blog by the CEO / founder, telling we are under loss since there is no financial support! and we are closing it, by just keeping the website and docs of prev version alive!

I was heartbroken , for days!
This takes the top place for favourite oss project

Btw
It has high no. of stars in github than Mongo db, reddis, etc..

!Rant

Need some help from anyone experience with MEAN.

Do you have a separate cache for data or is Mongo the cache as well?

Basically we have 500GB+ DB of data, how would you architect a MEAN system around it so that it's fast and stable

I keep having these ideas of a steam like interface for transfering money and buying virtual items, but I can't for the life of me figure out how i would go about it other then a basic flask mongo db set up which would be ripe for malicious attacks

I need to work on a mysql project for university but i know nothing about it,

Can you tell where is it deployed for production purpose, like mongo DB stuff can be deployed on heroku

Hey errrbody!!!

I'm banging out a couple "showcase" mobile apps for practice, portfolio, and/or as potential templating tools.

I have no issue writing the code, I just wanted to see if I could get a couple pointers as far as user databases go. I'd like to have some "user profile" features generated from a FB...vlike profile images, name, address, contact, yadda yadda yadda. I usually use Firebase, but I am still having a little trouble with the more advanced stuff when it comes to integrating users profile data. I can get values from Google and whatnot, but I'd like to see what my other options are on the smaller scale.

I am currently writing code in Flutter/Dart, ReactJS( not native!), Vanilla Js, Python, and CPP.

I know there's options for client side storage like Shared Prefs, Sqflite, etc, as well as server/DB side stuff like Firebase, Aws, Mongo, Node, SQL, etc- you get the idea.
I just want something with decent documentation that's reliable, not a massive undertaking (at least not for all this little stuff, anyways) and could potentially be a go-to platform configuration in the future. It'd be cool to wire in my Flutter and js shit of possible, bit honestly I'm cool with having separate setups for the time being. Any extra input regarding the use of python and/or cpp as well (either separately or with mobile) would be rad as fuck!!!
I do realize it's a pretty vast area to cover, but I figured it couldn't hurt to see what everyone likes to use for full-stack setups.
Thanks!!!!

Can anyone tell me how I can integrate Mongo DB with golang?

I found go-bongo, but it's not well documented.

Is there a portable DB format like sqlite but stores data like Mongo.

Each record contains key value pairs.

I guess I could install Mongo again... But kinda want to play with the data first. Pulls from a web api

I guess other alternative is to just save the json responses to disk in separate folders and files for now...

And abstract the DB layer behind an interface

I dont get it. Please give me one good reason to use mongoose with a mongoDB.
Once upon a time it might have made sense to use a schema for the db. Today the native driver supports schemas and can check them on inserting. Nevermind one should validate the data before its hitting the db. I listened to an 1hr podcast last week where one of the maintainers tried to give reasons why its might be a good idea to use mogoose, and he failed miserably.
It introduces dependencies that are useless, it doesnt really abstract anything useful from the native driver, its TS support is shit and I dont like the API.
Every time I see someone use it he either fails or doesnt explain at all why to use it. Its so redundant it makes me angry. We have enough abstraction already. We really dont need more code that doesnt provide value. Please just use mongo the way the people of mongoDB intended it to be used.

Just a question about a generic social app. Using mongodb , 3 entities ,like comment and post . how do I display posts in feeds with comment count and like count . since its mongodb I can't do joins . the other way is to maintain a data structure on the server side . or yet another way would be making 2 extra queries to db for retrieving like and comments count . Any other way this is possible or is it possible to form a query in mongo db to retrieve all 3 at the same time???

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?

Can anyone Tell me. Is there any way to use node js with MySQL or Mongo Db on TERMUX Android.

If you Help me. I will be very thankful to you.
I want to learn but I don't have computer.

Guessing my rant free streak is over. Trying to connect to a mongo atlas cluster. Just migrated from mlab as mongo Inc is discontinuing the heroku add on.
Migration went well. I can connect to atlas cluster via mongo shell.
Reactive mongo claims it supports dns seed list. I add mongodb+srv connection string. Doesn't work.
I go back to atlas and allow all ips access (migrating staging dB first to make sure all is well so I can whitelist all ips) - > send a request-> mongo error. No primary node is available.
Disconnect from my network, connect to another network, same thing. I push the connection string to my server, test using an ssl connection to make a request, still no primary node available. I am about to lose my mind.

Spent the whole day trying to get php driver for mongoDB to work.. made a php script that connects to remote db, the connection kept returning null/false no matter what i did.. in the end i uncommented a code below that fetches data with the "null" connection and suddenly I see data printed out 😐 well f you too very much 😡

Tomorrow I'll finally play with mongo 😊 i hope it won't be too much of a pain with php

just 'Hello world' me trying to make a restful api.
*Got Ktor, loved the koltin, hated the deploy, quit.
*Got Django, loved the python, hated the sql migration, quit.
*Got Node, loved everything, hated mongo, can't quit now...
*Got Firebase DB now, I feel the hate monster...ghostly voices, saying, Work my slave, build it... dont stop, 'cause we're right behind you...

....and we're waiting for you

Where can find an all in one guide to set up/configure a ELK environment manually from the tars (not yum, apt-get, docker image)?

I am following the component docs from Elastic but not sure how each component integrates with each other or how to set the mongo connection (DB is not local)

Full Stack:

Mongo DB

Ok so, i have no idea where i can ask this kinda thing so i'm asking it here (i know i could do like stackexchange or dead aws discord servers, ... nvm you know why i'm not going that route).

Anyways,
I'm looking for a comparison between a mongo+node setup on a basic t1.micro instance and a lambda+dynamodb setup.

Each one has it's perks obviously but i guess i sorta prefer whichever one gives best performance on the free tier.

I do know dynamo has 25 reads and 25 writes a second on the free tier, which might be a little less ? I really have no clue.

But how many writes/reads would a basic mongo setup be able to achieve on the t1.micro instance ? Any idea? Do share your experiences with these architectures as well. I'm sort of a newb with serverless, the downsides aren't worth it for me but I'm learning it nevertheless. It sorta tickles some sort of self-torture curiosity fetish (need more self-research to back that).
