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!2 -
I have been keeping this inside for long time and I need to rant it somewhere and hear your opinion.
So I'm working as a Team Lead Developer at a small company remotely based in Netherlands, I've been working there for about 8 years now and I am the only developer left, so the company basically consists of me and the owner of the company which is also the project manager.
As my role title says I am responsible for many things, I maintain multiple environments:
- Maintain Web Version of the App
- Maintain A Cordova app for Android, iOS and Windows
- Working with pure JavaScript (ES5..) and CSS
- Development and maintenance of Cordova Plugins for the project in Java/Swift
- Trying to keep things stable while trying very hard to transit ancient code to new standards
- Testing, Testing, Testing
- Keeping App Stable without a single Testing Unit (sadly yes..)
- Just pure JavaScript no framework apart from JQuery and Bootstrap for which I strongly insist to be removed and its being slowly done.
On the backend side I maintain:
- A Symfony project
- MySQL
- RabbitMQ
- AWS
- FCM
- Stripe/In-App Purchases
- Other things I can't disclose
I can't disclose the nature of the app but the app is quite rich in features and complex its limited to certain regions only but so far we have around 100K monthly users on all platforms, it involves too much work especially because I am the only developer there so when I am implementing some feature on one side I also have to think about the other side so I need to constantly switch between different languages and environments when working, not to mention I have to maintain a very old code and the Project Owner doesn't want to transit to some more modern technologies as that would be expensive.
The last raise I had was 3 years ago, and so far he hasn't invested in anything to improve my development process, as an example we have an iOS version of the app in Cordova which of course involves building , testing, working on both frontend and native side and etc., and I am working in a somewhat slow virtual machine of Monterey with just 16 GB of RAM which consumed days of my free time just to get it working and when I'm running it I need to close other apps, keep in mind I am working there for about 8 years.
The last time I needed to reconfigure my work computer and setup the virtual machine it costed me 4 days of small unpaid holiday I had taken for Christmas, just because he doesn't have the enough money to provide me with a decent MacBook laptop. I do get that its not a large company, but still I am the only developer there its not like he needs to keep paying 10 Developers.
Also:
- I don't get paid vacation
- I don't have paid holiday
- I don't have paid sick days
- My Monthly salary is 2000 euro GROSS (before taxes) which hourly translates to 12 Euro per hour
- I have to pay taxes by myself
- Working remotely has its own expenses: food, heating, electricity, internet and etc.
- There are few other technical stuff I am responsible of which I can't disclose in this post.
I don't know if I'm overacting and asking a lot, but summarizing everything the only expense he has regarding me is the 2000 euro he sends me on which of course he doesn't need to pay taxes as I'm doing that in my country.
Apart from that just in case I spend my free time in keeping myself updated with other tech which I would say I fairly experienced with like: Flutter/Dart, ES6, NodeJS, Express, GraphQL, MongoDB, WebSockets, ReactJS, React Native just to name few, some I know better than the other and still I feel like I don't get what I deserve.
What do you think, do I ask a lot or should I start searching for other job?24 -
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.6

I always had this mentality that I shouldn’t rely on a certain library or framework for my entire project because what if one day they stop supporting it. (Yeah I’m talking to u vuetify) That’s why I came up with this code structure that for everything that I wanna do I have a ‘driver’ library all coded by myself that interacts with that third party framework or library so if they stop supporting it I could just change a couple of lines of code in my driver file and my codebase should be working again. But I feel like this ‘driver’ approach is not the most efficient way of going in terms of memory usage. Do you guys think I should keep it simple and directly use those libraries or this is actually not a bad approach.7

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.8

What cheap/good quality node.js hosting provider for nodejs/react/mongodb app do you suggest? (including sale, black friday etc.)10

I'd like to learn go while building a web backend. but I'm not how should I start it. I mean, should I use any framework?
I'd like to use MongoDB, so a mongoose like ORM/library would be awesome8 -
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?
"connect ECONNREFUSED 127.0.0.1:27017"
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'7 -
I completely *detest* that the MongoDB *shell* is just a fucking jS interpreter with extra API calls sprinkled on top and whoever came up with that idea should have all their commits reverted immediately, working with that thing is a punishment!
I don't even know a way to parse and chew through the json it spits out in my own json viewers, as it's "Extended", and none of my editors understand that!
Ugh, haven't been this frustrated with a tool for a while...5 -
Yukki Music Bot
okay so, I'm bout to post my first rant and its basically about this telegram bot whose dev team I'm a part of, Yukki Music Bot.
It all started around April 2021 when most of us were busy streaming Netflix, chilling and locked up due to Covid that some people decided to make something interesting and for the community.
It was at first just a simple bot which just played music on call but now, due to the countless efforts and time by the Team Yukki, now you can even stream Ipl in telegram voice chat! and almost all of the music platforms are supported by Yukki >~<.
Check it out at @TeamYukki in GitHub!4 -
For those learning MongoDB and struggling to find resources on sharding/replication, this video tutorial from Vemara Hub on YouTube is fantastic and his blog also has it in article form. This is where mongo shines.
