Job interview

Hired a new backend Dev. He writes a script and sends it for testing...
Tester: "It's not working..."
Backend Dev: Goes to Mongo and deletes the tester's whole profile...

I cant control my laughter every time I remember this incident...He claimed it was a mistake, I don't think that it was a mistake...the tester had it coming...
"It's not working" that's all he says every time...I mean at least give me something to start with...!

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

Cool. 300$ in Google Cloud credits. Maybe I can get to one of those cool projects I’ve been wanting to get to.
spins up server
installs npm
installs mongo
installs express
installs vue
installs material design components
makes title bar and navigation

*okay, good enough for now, i’ll come back later*

*never gets around to it, and 300$ in free credits get exhausted by server running 24/7*

I think I will ship a free open-source messenger with end-to-end encryption soon.

With zero maintenance cost, it’ll be awesome to watch it grow and become popular or remain unknown and become an everlasting portfolio project.

So I created Heroku account with free NodeJS dyno ($0/mo), set up UptimeRobot for it to not fall asleep ($0/mo), plugged in MongoDB (around 700mb for free) and Redis for api rate limiting (30 mb of ram for free, enough if I’m going to purge the whole database each three seconds, and there’ll be only api hit counters), set up GitHub auto deployment.

So, backend will be in nodejs, cryptico will manage private/public keys stuff, express will be responsible for api, I also decided to plug in Helmet and Sqreen, just to be sure.

Actual data will be stored in mongo, rate limit counters – in redis.

Frontend will probably be implemented in React, hosted for free at GitHub pages. I also can attach a custom domain there, let’s see if I can attach it to Freenom garbage.

So, here we go, starting up modern nosql-nodejs-react application completely for free.

If it blasts off, I’m moving to Clojure + Cassandra for backend.

And the last thing. It’ll be end-to-end encrypted. That means if it blasts off, it will probably attract evil russian government. They’ll want me to give him keys. It’ll be impossible, you know. But they doesn’t accept that answer. So if I accidentally stop posting there, please tell my girl that I love her and I’m probably dead or captured

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!

99% of our server-side code is Python and PHP (legacy applications).

Asked a junior dev to make a small update to a PHP site so we could have it run some cleanup server side. Plenty of existing PHP code to look at and piece something together. Should be 50 lines max.

Did he use the existing PHP code to do this task? Nope. Did he at least use Python? Nope.

Node.js

His response?

"I couldn't figure it out and Node.js seemed to have good support for mongo so I used that instead."

We have 0 lines of server side javascript. Never had node installed. Literally none of the devs use node here. Not only is this completely outside of our tech stack, but he had to take the time to learn Node and JS just because he thought it was easier.

Much would of rather he put in twice as much time to learn the tools of our stack.

Do you read it as Mongo-D or Mon-God?

On the presentation for my database project my team and I showed a NodeJS + Mongo + VueJS project with cloud storage capability, nothing fancy but did everything from scratch (from token auth and system encryption to the frontend CSS and the database) the teacher made some questions and meh'd at it.

Behold team two's project, WordPress with a standard template and phpMyAdmin, teacher loves it because "it's so beautiful"

Guess who just failed that class?

God I love college, it's the best time investment I've ever done and it'll surely pay out.

Wrote angular service, named it "MongoService", handles calls/requests to mongodb. Spent an hour wondering why it wasn't running one of my functions from controller. Just realized I am calling MangoService instead of Mongo. Lord help me.

Database tip of the day:

Spent hours on Amazon's DynamoDB and ultimately found it couldn't do what I wanted, not without a complicated workaround.

Switched to Mongo and had it working in literally under 5 minutes.

Hooray for Mongo 😀

Learning Node.js, Express, React.js, ES6, and Mongo all at once. Haven't been this excited about programming since college. This stuff is incredible!

That's real helpful mongo

Usually I develop in python, mongo, cordova and node. Few days back I installed Windows on my laptop cause I needed to use the Visual Studio for a specific task. Then I thought that if I can setup the python, mongo, cordova and node stack on Windows then I don't need to switch between Linux and Windows frequently. And that was a horrible decision.

It took almost 8-10 hours to setup that shit, and still I couldn't make it work. There are so much complexities and those do not make any fucking sense! I mean why the hell I need to add the python path to the environment variables, and then again add the pip path separately. Then mongodb can not autostart. And finally I needed to make and build a package, and that waa the moment when I just scrapped it.

It takes me 2-3 hours to setup a fresh Linux box (which supports apt) including the OS installation. Same for the osX. I still wonder that why Microsoft does this! If Windows is for non-dev and non-tech people then why don't they release a Windows developer edition? Developing anything except ASP.NET and Java in Windows is a fucking nightmare for me!

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

Had an idea for an app. I started writing the prototype in Node since I just had a simple API in mind. Wanted to have some very basoc crud functionality going and then hook up a nice interface to it. It has to do with logistics and analytics so I just wanted to start sketching something small, and being that i have been successful in doing an API like this in the pass with node and mongo for a local company I said why not.

I have finished a good chunk of it. Gotta love that js productivity. But what tripped me out about it was:

Check how big the folder size is: 387mb

EXCUSE ME??!!

I tripped, there was no way in hell this shit was that heavy. I am basically using Koi(to give it a whirl instead of express, gotta start testing koi sometimes right?) And some joi with morgan and winston. That is it. I am using mongo since legit its the only one i know, even with that there really can't be that much right?

Check node_modules size.....10mb....wtf? What
Wait
Did it?

Sure as shit....forgot that i was storing the mongo data folder inside the app's root folder.

This would have been nothing if it would have taken me 30 seconds to figure it out.

I was losing my mind for 30 mins before i decided to properly verify

I need some sleep

Fun day, lots of relief and catharsis!

Client I was wanting to fire has apparently decided that the long term support contract I knew was bullshit from go will instead be handled by IBM India and it's my job to train them in the "application." Having worked with this team (the majority of whom have been out of university for less than a year), I can say categorically that the best of them can barely manage to copy and paste jQuery examples from SO, so best of fucking luck.

I said, "great!," since I'd been planning on quitting anyways. I even handed them an SOW stating I would train them for 2 days on the application's design and structure, and included a rider they dutifully signed that stated, "design and structure will cover what is needed to maintain the application long term in terms of its basic routing, layout and any 'pages' that we have written for this application. The client acknowledges that 3rd party (non-[us]) documentation is available for the technologies used, but not written by [us], effective support of those platforms will devolve to their respective vendors on expiry of the current support contract."

Contract in hand, and client being too dumb to realize that their severing of the maintenance agreement voids their support contract, I can safely share what's not contractually covered:

- ReactiveX
- Stream based programming
- Angular 9
- Any of the APIs
- Dotnet core
- Purescript
- Kafka
- Spark
- Scala
- Redis
- K8s
- Postgres
- Mongo
- RabbitMQ
- Cassandra
- Cake
- pretty much anything not in a commit

I'm a little giddy just thinking about the massive world of hurt they've created for themselves. Couldn't have happened to nicer assholes.

Set up a server, code for hours using node and Mongo trying to realize your dream. FINALLY complete it after a lOOOng time of blood and sweat..

Then find out that a Noob who didn't know the first letter of web programming used FireBase and did what you did in a fraction of the time

I think I've reached the point where I can question what I've done, my purpose in life and.. As for my confidence I think it successfully descended during my last visit to the bathroom

Tldr; its a long introduction

Hi Ranters,

I've been on this app for quite a while now. As a shy cat watching from a distance and reading all kinds of rants. Anywho I feel comfortable enough to crawl out of my shell and introduce myself. Since I feel you guys together made such a pleasant and safe community, I'm really happy to be a part of it!

Anyway I'm Sam, 24 year old, from the Netherlands. My favorite color is green. Mostly the green you can find in nature. The one that calms you down:). I'm a very introverted person but always very curious and eager to learn new things.

I started to program when I was 12. I did assembly and C++. Because I liked making cheats for online games. Later I learned about C#, Java and Python. Mostly used it for web stuff, scraping, services etc. But also chatbots (for Skype for example).

Currently I'm 2 years in as a data scientist, mostly working in Python.

But on the side as a hobby and with an ambition I have a basic understanding of full stack development.
Mostly Nodejs, express, mongo, and frontend, no frameworks.

(I will later ask you guys some more questions about that! I could really use some advice!)

Anyway enough about me! Tell a bit about yourselves! Happy to get to know you all a little better!

So today, again, I discovered the importance of unitests.
I was solving this performance issue, in which we had a few update actions for multiple entities in mongo, but it took FOREVER to complete, even when I unified it into one bulkWrite command.
Since the unified write did improve performance slightly, and we wanted to move on, we decided to let this bug go.
So there I was committing my changes when I got a rejection from the pre-commit hook since I didn't have enough unitests coverage.
Ok, let's start writing some unitests.
Some unitests also needed to test the bulk write. So there I was comparing expected with actual result, and suddenly I got a huge facepalm.
Apparently some rogue for loop iterated all entities again for each entity that needed update. So instead of getting one update per entity, I got N identical update commands per each of the N entities 🤦‍♂️
Needless to say, fixing this fixed the performance bug entirely.
Thank you unitests and pre-commit hooks!

Our boss did always the same thing. When there was a BIG potential customer who indicates a small interest in our software, then he lied constantly about features. After the customer bought our software we got a deadline and should develop the missing features. I could remember two features: The first one was a quote tool for a car transport company. The tool should estimate a price for a transportation from an email with no structure and the other one was an API which should be possible to write dynamicly to MySQL, MariaDB, Postgres, MSSQL, DB2, Mongo or better said any possible dbms. The API should guess the structure of the dbs and offer CRUD actions. The funny thing is must write the api with go. Yeah dynamic and GO.

At some time, we told him we wont make any overtime and if the deadline is not possible we told that immediatly the customers, so that they call him. Thank god I don't work anymore in this company.

I wrote a node + vue web app that consumes bing api and lets you block specific hosts with a click, and I have some thoughts I need to post somewhere.

My main motivation for this it is that the search results I've been getting with the big search engines are lacking a lot of quality. The SEO situation right now is very complex but the bottom line is that there is a lot of white hat SEO abuse.

Commercial companies are fucking up the internet very hard. Search results have become way too profit oriented thus unneutral. Personal blogs are becoming very rare. Information is losing quality and sites are losing identity. The internet is consollidating.

So, I decided to write something to help me give this situation the middle finger.

I wrote this because I consider the ability to block specific sites a basic universal right. If you were ripped off by a website or you just don't like it, then you should be able to block said site from your search results. It's not rocket science.

Google used to have this feature integrated but they removed it in 2013. They also had an extension that did this client side, but they removed it in 2018 too. We're years past the time where Google forgot their "Don't be evil" motto.

AFAIK, the only search engine on earth that lets you block sites is millionshort.com, but if you block too many sites, the performance degrades. And the company that runs it is a for profit too.

There is a third party extension that blocks sites called uBlacklist. The problem is that it only works on google. I wrote my app so as to escape google's tracking clutches, ads and their annoying products showing up in between my results.

But aside uBlacklist does the same thing as my app, including the limitation that this isn't an actual search engine, it's just filtering search results after they are generated.

This is far from ideal because filter results before the results are generated would be much more preferred.

But developing a search engine is prohibitively expensive to both index and rank pages for a single person. Which is sad, but can't do much about it.

I'm also thinking of implementing the ability promote certain sites, the opposite to blocking, so these promoted sites would get more priority within the results.

I guess I would have to move the promoted sites between all pages I fetched to the first page/s, but client side.

But this is suboptimal compared to having actual access to the rank algorithm, where you could promote sites in a smarter way, but again, I can't build a search engine by myself.

I'm using mongo to cache the results, so with a click of a button I can retrieve the results of a previous query without hitting bing. So far a couple of queries don't seem to bring much performance or space issues.

On using bing: bing is basically the only realiable API option I could find that was hobby cost worthy. Most microsoft products are usually my last choice.

Bing is giving me a 7 day free trial of their search API until I register a CC. They offer a free tier, but I'm not sure if that's only for these 7 days. Otherwise, I'm gonna need to pay like 5$.

Paying or not, having to use a CC to use this software I wrote sucks balls.

So far the usage of this app has resulted in me becoming more critical of sites and finding sites of better quality. I think overall it helps me to become a better programmer, all the while having better protection of my privacy.

One not upside is that I'm the only one curating myself, whereas I could benefit from other people that I trust own block/promote lists.

I will git push it somewhere at some point, but it does require some more work:
I would want to add a docker-compose script to make it easy to start, and I didn't write any tests unfortunately (I did use eslint for both apps, though).
The performance is not excellent (the app has not experienced blocks so far, but it does make the coolers spin after a bit) because the algorithms I wrote were very POC.
But it took me some time to write it, and I need to catch some breath.

There are other more open efforts that seem to be more ethical, but they are usually hard to use or just incomplete.

commoncrawl.org is a free index of the web. one problem I found is that it doesn't seem to index everything (for example, it doesn't seem to index the blog of a friend I know that has been writing for years and is indexed by google).

it also requires knowledge on reading warc files, which will surely require some time investment to learn.

it also seems kinda slow for responses,

it is also generated only once a month, and I would still have little idea on how to implement a pagerank algorithm, let alone code it.

mongo in slang means idiot, which comes from the term mongol or mongoloid, which is a deprecated word that used to be used for sufferers of down syndrome. So MongoDB means "Down Syndrom Data Base"

Also mongo means huge, so it may have been named after that.

I recently met Mongo and my life has changed forever.

My God, MongoDB + GraphQL is one of the best combo in JS. Absolutely loving it!

Idiots. Just... Fucking Idiots.

Junior Frontend dev got a feature to implement. Decided to add a field to a set of mongo collections. I'm the responsible adult for those collections. Talked to the junior - told it, "don't do that, you will lose the data you are adding later". Junior says "will not happen", and goes on to try and prove It is "Right". Problem? Junior is an Idiot. did not trigger the data loss scenario. So... Junior got his TL to talk to the RND manager. And those Idiots Decided that the implementation will go forward as is.

Data loss will happen. QA will not find it. Only the client will experience the data loss, and complain....

Thing that just occurred to me.

Write backend of website in Node with Mongo.

Write front end of website by using PHP to echo data from mongo and inline styles. PHP will also echo any inline JS that needs to make AJAX calls back to handle responsiveness.

Write a website with JS as its backend and PHP as its front end because the world has gone absolutely mad and you dgaf anymore.

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.

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.

in my native language.

mongo = "expensive"

Mongo DB

😂

So... About a month ago 2 interns started a project from scratch at my company. My boss gave them a project to follow as an example (more for the api and database side).

Wednesday they ended the internship and I've began to help fix the rest of the kinks that were left to be fixed. Friday we were finishing up the app and api to send to the client for tests. The database was created with 4 tables that were equal in structure... Imagine that you need a table for orders and they have status like pending, cancelled, finished and accepted. What they've done was they created 4 tables, one for each status....

Why the hell would you do this???

I always feel odd when I hear about MongoDB. Cuz mongo is a German curse word for someone with down syndrom...

Thinking about transferring the majority project from mongo to MySQL. It makes sense rationally but - feels like there is a creeping darkness is looming over me.

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....

Running Windows on crappy hardware is the worst!! takes forever to install or upgrade SQL Server.

Just had a discussion with a coworker. I noticed he was storing dates as string in mongodb, saying it was better for comparison and because he stored them in UTC. WTH, mongo already stores all dates in UTC and a string date is imposible to compare. I wasted 8 hours finding that last part out.

Another day, another company that doesn’t live up to its own hype.

This time interviewing for a company that only want people who are willing to start with the language they currently know but learn other programming languages and not shy away from new things.

Brilliant, I’m up for that. I love learning and want to be at a place that values learning. I’ve got 20+ years of experience and I’ve learnt all sorts in that time to stay relevant. Currently I’m a c# dev, but I’ve worked on projects using JavaScript & Typescript, Angular, React etc. Done front end and back end, taught myself mongo and architecture. Point is that I have a proven track record of learning.

To cut a long story short, they give me a .net test. Nothing special about it. I have a 4 hour chat. And a week later I’m rejected because I don’t do Python. WTF?!

I thought this place was all about allowing people to learn if they were willing, not about what they know right now. I’m calling bullshit.

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?!?

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?

Boooooy symfony has changed a lot since laaaaaaaaast time I used it a long time ago.

Some days ago I finished a little project I built using express and mongo. I want to port it into symfony to see how the newest version (which is 4) fares and I must say. I am really impressed and happy with what I am seeing :D

This sucks because I am going to be dying to use this at work and I know that I am not going to be able to use it unless i act all sneaky and shit

confession time:
I am php laravel developer with little knowledge about nodejs.
I got selected by one startup as nodejs developer.
frankly I am not better nodejs developer than my competition who were rejected.

I completed oral interview with my nodejs theory knowledge at a time of technical round , they gave us task to create crud with fantastic front end and nodejs mongo as a back end.

I developed front end in bootstrap but at a time of backend, I just copy paste code from github.

and changed everything variable and other proof to hide reality. in mean time other candidates were actually coding everything then I took time to understand this code and I submitted after few candidates.

in last round they ask me to explain code which I explained properly and I get salary 40k/month INR.

I know it is cheating but I wanted this job badly.

Today a co-worker (I am going to call him 'boss') ask to another co-worker (I am goin to call it 'useless piece of shit' or 'ups') to explain to me a new task, becaus boss was to bussy with a new release for a client.

Idk how but ups managed to explain all wrong, like terribly wrong.

Ups: "Dev, all you have to do is fix some queries from local files"

Dev: "Ok, seems legit"

Try the local files, nothing happend

Dev: "weird... ups why this is happening?"

Ups: "I know the same as you, ask boss."

Dev: "boss this."

Boss: "what the actual what? ... this is all wrong. The config file is in mongo, in this IP, we don't use local files anymore. I tell ups to explain this to you so I can atay focused on this other task, but now I lost the double amount of time"

Dev: "oh... sorry, I will fix the remote queries"

I hate ups, every fucking time soneone need something from him this happend or worst...

This rant must be because of my oldness. I was never into Pokemon, but my oldest kid was.

So the hashtag for Pokemon Go makes little sense to me. It could just as easy be an insulting Poke Mongo (ie harazzing a Down's Syndrome person) as Pokemon Go.

There. Out of my system. Please carry on.

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.....

Product Owner: Hey, can you guys own this incredibly fragile legacy app built with Grails, Angular and Mongo?

Me: No

PO: Go on. You can rebuild it!

Me: Sigh.. ok

- 6 months later -

Me: When can we rebuild this bloody app??

PO: lol sry no budget lmao!

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.

If I learn React, Redux, Mongo, Express and Node, will I be able to build a full web application?

I'm still unable to find a single advantage of using the Firebase Database over MongoDB, yet people keep suggesting me to do so.
WHY? I can host Mongo for free on my own server and won't have to worry about *READING* costing money!

haha :D

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?

Has anyone here used MongoDB for relational databases? I am trying to use MySQL with Node but I feel like the whole thing is a mess. There are some ORMs like Knex or Sequelize for MySQL but they are pretty crap. I am thinking if I should just move onto MongoDB instead of MySQL, at the same time I feel a little dirty to store relational data in a document store :(

Netbeans, because its awesome!! no other explanation lol

Fucking mongo, fucking nested documents in nested documents that need to be filtered. I'm either really fucking dumb, the query is hard or both.

Why is it so hard to install mongodb on ubuntu 16.04? I've spend 3 hours installing that junk.

Hey there people, I have a few questions regarding neo4j. Your experience could also be very useful to me here @dfox.

1. Is neo4j good for storing user data, like password hashes, etc.. In addition to the regular relationships with other components of the ecosystem

2. Is neo4j good enough to accommodate a really large number of users..

3. Does DevRant use a dual database, like user info in Mongo and relationships like comments and ++ on neo4j or is it like everything on neo4j

For q.3, if you're not @dfox then just provide an idea of how you would handle the situation.

Start mongo, start my node server, start the app, quick "5mins" look on dev rant started 30mins ago!

Some facepalm things I've discovered recently:

- Node's require("http") doesn't work for https - you have to require("https") specifically.

- Mongofiles (command line utility for Mongo, imports files as GridFS) cannot input more than one file at a time. Regex doesn't work. [Ended up making a puny Powershell script to do it].

- Airtable doesn't let you download your attachments, even if you export a csv - it's just a url to the image on their cloud.

It's been an exhausting day.

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"

The fog of war over all that happened with my change of team is starting to dissipate.
3 people were involved and there were 4 different versions of the whole situtations, but from what I've been able to collect it looks like the company is expanding and one of the mail KPI for the current team leaders is how good they are at creating a NEW generation of team leaders, to take care of the new entries.
My previous team leader told me about all these new growth perspectives and the junior entries I could manage, knowing very well of the desire I have previously expressed of being a senior dev with my small group of juniors to teach.

I declined the offer, stating that this whole year has been exhausting. Every single time I've tried anything (using modules for new components on our old web client, tsdoc to document our types, suggesting technologies like ANYTHING BUT ANGULAR AND MONGO, telling how removing down migrations was a retarded move) my suggestions were either shrugged off or flat out refused. Let alone how every time I was proven right, except for angular but give it time and that will bite their tail as well.
Don't get me wrong: they are well withing their right when they take all those decisions, and more. But I DO NOT PLAN on selling a plethora of bad decisions to a new stack of devs as if they were the gold standard.
"I understand your reasons; you, as a company, need a well coordinated team all running towards a goal; loose cannons are harmful.
But now I need you to understand me: I do not agree with your technical direction. I never lied before and I will not start now. Promotions don't matter nearly as much as my integrity, and integrity in my world means speaking up about problems. Your position is perfectly valid, but mine is as well and they can't be reconciled. If I were you I'd make myself a favor and make sure IHateForALiving doesn't become a team leader; given your direction, I'm not the man you want right now".

As mentioned, one of the KPI for team leaders is how succesfull they are in finding new team leaders, and trying to turn me into one didn't end well; I love sharing knowledge, but being honest to myself is far more important to me. So this meant my previous team leader failed in a very big task, and thus was demoted? At the same time, I've been there for 2 years now so they're not really eager to replace me, but I'm under strict examination too as of now.

Rant!
Shifted to new office few days back.
Just had to put up with the shitty intermittent internet connection.
SSH failing and coming out for every 50 secs.
Trying to take Mongo Dump and restore for the past 2 hours. Finally! ufff.

When the network is disconnected SSH gets disconnected. Fine. Acceptable. Again, when the network gets connected, it should start from the same place right ? Dumb Enough. But i wanted that today.

Kubernetes question:
So far I've created two pods, mongo & Go
Exposed those pods using services

Their IP is 10.x.x.x and accessible from my machine only (virtual lan I'm guessing only known to host), but my machine's network ip is 192.x.x.x therefore, not accessible from outside world and to do so I need to put nginx in front to receive requests and route them internally.

Is there a way in kubernetes to make it work like nginx in terms of:

Kubernetes listen to port 80 (for example) route based on received url. As you know in enginx we define a server block with server domain_name.tld

Anything similar in kubernetes? I've cheked ingress-nginx controller, and also saw LoadBalancer but that requires a cloud provider.

If anyone can also give an example it would be great, so far examples I checked ended up screwing my setup and had to reset kubectl to get things back working

!rant

I'm a rather young developer, self-learned everything and started when I was 13 (now 20) but I still feel like I'm a total beginner since I have not yet mastered the things I am OK at.

Php (laravel, since it makes things much easier), js (jquery, bad at vanilla, have used angular and ember but not mastered), node, linux, html, css, photoshop, illustrator, sql, mongo and windows servers

I know little about many things, can create things that are asked of me but the methods I use are rather bad imo.. ex: I finish coding a section of a site, but when I need to add a new feature I find myself rewriting most of the stuff to add the new feature and in the end still feeling like the code could be optimized further, even though I have no idea how.

TL;DR I write bad code, but things work as long as I am monitoring them. I know little about alot of stuff but mastered none of them.

What should I do? Go to school for programming?

SO , i just ran into this database called ArangoDB and it claims to single handedly beat Mongo,Neo4j,Postgres and claims to be capable of handling any use case you can throw at it.

If anyone could verify this claim , such an ideal database just makes me question it's existence.

Regretting I ever put Mongo on this app's stack... It's been great to learn in the process, but man it can be a bitch to setup sometimes...

When your boss wants to use Mongo and Node because its trendy and popular.

My company wanted to move old desktop applications to web and use angularJS. Finally, "new" tech. Not allowed to use node and Mongo because maybe someone who joins the Web team don't know Javascript and only sql experience ... Time to dust off my CV

When you request a bugfix but the bug is renewed.

So, guys what do we call this level of skill ?

I'm pretty familiar with SQL. It used to scare me, but now, years on, I'm super comfortable with it, and I don't really get why anyone would need anything else, generally speaking. Having said that, just tried to play with mongodb for a minute, and holy shit, that is some weird, weird stuff. I read all of the marketing fluff on the site, but I still am at a loss. Is it just that people don't want to be bothered to learn SQL syntax or use an ORM, or make a REST API, so they went off and created a weird JSON thing?

Not trying to be a douchebag, not trying to criticize. I honestly do not get it. Why does this exist?

I just spent 2 hours tearing apart an express app to figure out what was wrong... turned out I hadn't started the mongo server. Doh!

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! 👍

Like seriously how fucked up are those ORMs? Prisma “yeah we support mongodb, but we will force you to write in a relational way.” I always hit on hard walls whenever ever I try an ORM in my projects.

Don’t get me wrong they are good for dummy stuff. But if you want to go a little bit crazy with mongo, embedded documents with refs it’s a mess…

Typescript and good old mongodb adapter bb anything else.

Hopefully at work we have successfully migrated from a combination of MySQL and Mongo to only Postgres. Also we finally split up our monolith into medium sized services, so we can actually do something interesting and update our dependencies.
And port one of the services from Java Struts to Django..
..but that is only if developers were to set the plan...if sales/management: new feature here! new feature there! sell sell sell! No time for maintenance!

What's with all the hate towards mongo as of late? Just a few years ago it was all the rage.

I haven't yet used it myself, I just find it to be a sudden stark contrast in opinion

Just got off a call with Mongo expert... Seems it's not good for large systems that need to be fast and scale...

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 new stack is: VUE, TS, SCSS, AWS, CSI, IBS, HIV, SSR and Mongo

After a year of using mongo in prod and personal projects I have realised some things. Its really nice early on the project, especially when there are changing requirements and for small projects or proof of concepts.
But when you make commercial software things tend to get more complex and relational. Stakeholders want reporting and even a report building which a document store isn't the best at.
With most projects projects when they get big things get relational and this becomes more and more expensive to handle in terms of compute power and developer time.
I don't doubt mongo has its place, maybe as an secondary specialised data store or if the project is inherently document oriented.
Blog over.

Bored and want something to do? Learn MongoDB. There’s SO many great resources out there! I have legit enjoyed these first three courses in Mongo University (+1 on Udemy).

So I accidentally used an email as a username to create an account through Jira for mongodb to report a bug.. That apparently breaks the entire Jira login system. I cant recover my account, and I can't create another account because my email is already in use.. Thanks Jira for deciding I'm going to bar before I go home today...

What cheap/good quality node.js hosting provider for nodejs/react/mongodb app do you suggest? (including sale, black friday etc.)

Well,
I went ahead and tested t2.micro and lambda+dynamo(free tier)

You definitely get better performance and load handing with lambda+dynamo (5rcu+5wcu)

Tested the two with wrk and a simple GET which reads an item from a database of 90k items.

I could share more details with you if youre interested, but with 2000 requests, 100 connections and 4 threads. I got about 26requests/s on ec2 and about 260r/s on lambda.

Latency for ec2 was about 28s.
Latency for lambda was about 22s.
(max load)

Project running in nodejs, angular and mongo. The boss just came and said he wants ReactJS now 😑

Everybody is bussy!

So let's going to give this mess to the one who never worked with mongo, does not know the objects in the DDBB, add to it some weird way to build queries in java to it and hope for everithing end well!

End well = need to be done today.

Guess what? Not for today! I have no clue of how to clean this shit.

You should learn Django instead of go, and MySQL instead of mongo

A question for Web developers:
I'm planing to start working on a web part of my project. Important part is that it's supposed to be working with MongoDB. The idea is to build a small digital library, so the main functionalities should be user registering, his login, querying database for books, showing list of results and viewing pdf files up to 200MB size.

Since I have almost no experience with web technologies, I would like to hear your advices and opinions on the technologies/languages I should use and learn. Should I go with JavaScript? Php? Something third?

Please note that this is a school project on which I'm working after my job, and not something to be deployed to customers.

Thank you

am i the only one who likes quoting Blazing Saddles in git commits?

most recent being adding mongo to a project.

I'm taking a look at neo4j after working a lot of mongo. Takes some getting used to but I think I could use it well for my next project.

Hello devs,

Any recommendation for managed mongodb service provider and server provider?

I am usually a fan of Digital Ocean but DO doesn't seem like a good option for mongodb (especially for mongo-noobs)

After delaying it for a few months, i'm finally starting to work on my final college project. It's going to be done in Java and Mongo. I'm not sure about the web part of the project, because i've never done anything in that part besides basic html and css. I'll probably try JavaScript.

Just wanted to share this because i've made the hardest step - actually started working on it.
Kinda feeling proud of myself.
Kinda feeling weird of being proud of such a thing.

Don't wish me luck, wish me the will to keep not giving up when it's the hardest

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..

I've just read the article about CloudPet, and honestly I am disgusted.
I don't even know what to say beyond that. I call out my team on basic stuff like forgetting to escape, but this?

hate to create huge one timers. got to build huge migrate tool (luckily there its not thousand of users) to migrate from mysl to mongo, then to upload assets properly at place. Its also got to be a new api test. Which also i wrote.(the api). Eveything is fine except the time. They wanted me to finish two days ago and i almost got it. But my head is about to explode and code is messy...

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

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

Neo4j vs Mongo vs SQL

Which one would you choose for a high density scalable database?

Please comment with your ideas about speed and scalability.

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.

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

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

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!!!!

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.

So... I got a simple task of choosing the best fitting NIDS/MIDS, as well as deploying it, configuring to fit a specific use case and monitor its outputs for one client at work today...

I'm a little... Anxious. At a first glance, setting up like... Snort... Doesn't seem all that difficult, but I have no idea where this takes me and if what I come up with will ultimately be useful or not... Until now I did simple service configuration changes like apache, nginx, php... And a bit of database management with things like mariadb, mysql, postgresql, mongo or elastic... I feel so... Out of my usual waters.

Do you guys thing a person without a title in network security (or... Any title for that matter) can even manage this?...

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

just 'Hello world' me trying to make a restful api.

Me: Assigned to do some NoSQL injections test cases in December on Jira by product owner.

After asking him about it, he said it can be vague and it’s only for developers to get an idea. I also have this restriction where I can’t really keep actually data or databases in our test sample application, so I could only mock mongodb. Product owner says just mongo is fine.

I do it. Now it’s January, product owner away for a month we so director is managing it. She then schedules me to talk to database team. I show them the very simple test cases which essentially just inject payloads I found online into different parameters specified in test case. They say if that’s it. I say yes. They say what’s the point of this. I said that it’s probably to test your database clients and ensure they’re rejecting bad Malicious input? They then keep asking but I’m just the dev and tell them the product owner is away. Then the guy calls my test case essentially useless and the others agree. Then they tell me to do it for other databases which I can’t mock like couchbase even tho my PO said it’s fine for mongo only.

Am I just being silly here? I am pretty new to working in a dev environment so please feel free to be blunt.

At what point should I feel my skills are strong enough to apply for a junior front end position? I'm going to be getting my bachelor's in May for CS and currently I am pretty familiar with HTML/CSS/JS, understand jQuery and bootstrap, know some basic node/express/Mongo (I know, I'm learning postgres, calm down), and now I'm kind of deep diving into angular.

He indeed is a great guy.

Job offer, searching for somebody with (amongst others):

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.

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 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?

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

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:
Express
Vue || Agular
Material Design
React Native || Electron
Mongo DB

Follow up sorta...

So I got pulled into a support issue on a day off. Some system was facing timeouts on our servers so had to investigate.

Over the weekend as part of the release, I released the ELK stack I built and today I used that to help.

Pretty much immediately pinpointed which machine was hanging though still had to investigate and confirm so split between KQL and checking the server logs.

One thing I've always griped about is how no one created schema docs for it mongo collections so can't easily figure out what they do or your to get the document needed.

Well guess it's my turn.... Because only I know the schema :)

What would you suggest to learn the fullstack js (with mongo,express, vue(example), nodeJs) first instead jumping into the specific framework?and wht are the next step after its been learned?

(Beginner perspective)

People love to talk crap about MongoDB but it's not horrible for getting in to NoSql databases. Is it good for extremely important production apps? No, but nobody is saying it is.

Ugh trying to refactor a Node.js MUD codebase to use mongodb. It currently accesses/stores it's data in json files via synchronous FS operations. Callback and/or .then hell, here I come!

Question for someone who uses Mongo Atlas Search:

If I'm only interested in autocomplete from the start of the text, which is more performant?

1) standard analyzer + edgeGram tokenizer

2) keyword analyzer + edgeGram tokenizer

I don't see why I should index separate words if I don't care about random positions :/

Thank you

Sometimes I'm questioning all my skills... I have a maven based project which uses hibernate as OGM to the mongo database. Everything working fine and already in a productive environment.

Now I changed some lines of code at the business logic to adjust for the changed database model. So far so good.

After compiling and running on the test environment: exception! "no persistence provider for Entity Manager named xy" are you fu***** kidding me? I changed nothing at that point!

Mongodb CEO and the developer who build this shit for brains interface should be tarred and feathered. Almost 90minutes in and I cannot connect to anything other than error codes. What in the actual fuck is your job other than to make it difficult for a "free tier" user to connect?

Oh ok another 20 minutes of work and you give me a bland beige error code like "```TLS/SSL is disabled. If possible, enable TLS/SSL to avoid security vulnerabilities.```"... um ok how do I enable it for your site, your database or on my computer... oh wait you don't say shit do you?

So now I'm fully 81 minutes into this shit show and all I get for error codes are these really descriptive gems 'getaddrinfo ENOTFOUND cluster0.hudbd.mongodb 'dot' net` comes up if I choose `mongo` with "connection string scheme" above it or `bad auth : Authentication failed'

I’ve been jumping on techs for a web application I wrote in Next.js and Mongo (mongoose) using Typescript.
The problem- I hate looking at codebase. Partly due to mongoose has a bug which makes type intelisense slow.
Moving forward, I’ve been creating different projects of the backend, in plain node typescript, in nest, in graphql but my inner self wasn’t satisfied.

Last night I deleted all the projects and decided not to change anything and continue working on the garbage code I’ve written a year ago.

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...

When is it a good idea to use linked lists?

In my pet project, I want to have a list of items with an index. The index of an item should be updateable, and the index of the other items should adjust.

A linked list would make it very easy to adjust the order since you just need to update the "next" node of 2 items, but I think this would make getting the index of items more troublesome.

What is the preferred way to do something like this, am I just overthinking it, and would updating all the indices of the items not be such a big job?

The project uses React and mongo (express-mongoose) btw, if that's important.

I read the whole documentation of Mongo Atlas Search and I still don't know if there is operator "greater than" for strings. I'm trying to implement my own "search_after" in the query because sort+skip is not a good idea and every time I google for a feature I end up in a forum where a PM says "Coming soon, we will prioritize this" and I know that things don't work like that

Why are all instructions for installing mongo complete blocks

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).

I'm looking into an app for work. It needs to connect to both a mongo and Kafka server using SSL or something, but different keys basically.

So need to load a jks file in the main() I think except I have 2 files.

I don't remember exactly how it works but I guess need to combine them into 1?

How do I load each though in app? Need to tell mongo, kafkaClient with one to use?
