I’m surrounded by idiots.
I’m continually reminded of that fact, but today I found something that really drives that point home.
Gather ‘round, everybody, it’s story time!
While working on a slow query ticket, I perused the code, finding several causes, and decided to run git blame on the files to see what dummy authored the mental diarrhea currently befouling my screen. As it turns out, the entire feature was written by mister legendary Apple golden boy “Finder’s Keeper” dev himself.
To give you the full scope of this mess, let me start at the frontend and work my way backward.
He wrote a javascript method that tracks whatever row was/is under the mouse in a table and dynamically removes/adds a “.row_selected” class on it. At least the js uses events (jQuery…) instead of a `setTimeout()` so it could be worse. But still, has he never heard of :hover? The function literally does nothing else, and the `selectedRow` var he stores the element reference in isn’t used elsewhere.
This function allows the user to better see the rows in the API Calls table, for which there is a also search feature — the very thing I’m tasked with fixing.
It’s worth noting that above the search feature are two inputs for a date range, with some helpful links like “last week” and “last month” … and “All”. It’s also worth noting that this table is for displaying search results of all the API requests and their responses for a given merchant… this table is enormous.
This search field for this table queries the backend on every character the user types. There’s no debouncing, no submit event, etc., so it triggers on every keystroke. The actual request runs through a layer of abstraction to parse out and log the user-entered date range, figure out where the request came from, and to map out some column names or add additional ones. It also does some hard to follow (and amazingly not injectable) orm condition building. It’s a mess of functional ugly.
The important columns in the table this query ultimately searches are not indexed, despite it only looking for “create_order” records — the largest of twenty-some types in the table. It also uses partial text matching (again: on. every. single. keystroke.) across two varchar(255)s that only ever hold <16 chars — and of which users only ever care about one at a time. After all of this, it filters the results based on some uncommented regexes, and worst of all: instead of fetching only one page’s worth of results like you’d expect, it fetches all of them at once and then discards what isn’t included by the paginator. So not only is this a guaranteed full table scan with partial text matching for every query (over millions to hundreds of millions of records), it’s that same full table scan for every single keystroke while the user types, and all but 25 records (user-selectable) get discarded — and then requeried when the user looks at the next page of results.
What the bloody fucking hell? I’d swear this idiot is an intern, but his code does (amazingly) actually work.
No wonder this search field nearly crashed one of the servers when someone actually tried using it.
Asdfajsdfk.rant fucking moron even when taking down the server hey bob pass me all the paperclips mysql murder terrible code slow query idiot can do no wrong but he’s the golden boy idiots repeatedly murdered mysql in the face21 -
Our software needs apache, php, mysql and node of certain versions installed. This is too many dependecies for our customers.
Let's dockerize!
Now they need docker, docker-compose, make, bash and python in a certain version. What an improvement!
I mean yes but hm.10 -
Let's say you have a MySQL database table for jobs. Each job has 1 associated ticket. You want to keep track if the ticket is closed or not. Every sane person creates jobs table, tickets table, keeps bool value for ticket state and relationship between them.
But because our database is designed by a half braindead amoeba, we have one table only, so each job has to be updated individually with a new ticket number and its state. Beacuse it sooo much faster to update (daily!) 13k jobs than just 100 tickets.
As a bonus - if the ticked is closed, the column "ticket_closed" is "No", if it's still open the value is "FALSE". Yes, both as varchar/strings.7 -
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.1 -
Hired a new BI developer. She tested reasonably ok in SQL, and certainly showed good strengths in visualising data, plus had a good attitude in the interview. We hired her. She broke her laptop the first day. We got her another then she complained the camera didn't work but didn't realise the lever in front of the camera was to move the privacy shutter off and on.
Assigned her some work of taking queries that are used in a BI tool that targets the transactional database directly, and re-jigging them for Snowflake which we're using as a data warehouse now, aggregating all our data into one place. Yet, she's struggling to understand why the SQL query she's pasted in doesn't work as-is.
I go over it again; the source schemas and tables are this, but in Snowflake we've named them this. She then bemoans how much work that is to change them all - I say use find and replace. She then struggles with Snowflake syntax errors and asks for a guide on T-SQL to Snowflake. I show her Google and say "this is what I did when I hit these problems - search for 'Snowflake equivalent to T-SQL getdate()' or 'how to get current date in Snowflake' but she still doesn't understand. I ask if she's every had to work between T-SQL and MySQL or MySQL and PostgreSQL or Oracle and so on and she says yes. I say the syntax isn't the same, is it? And she goes oh, now I understand.
She scored reasonably in her SQL test but I'm now concerned there's something fundamental missing in her grasp of SQL. I gave her a detailed demo of the tools, I explained in the interview and on her start about our move to a data warehouse for all our apps, and put her through some training plus gave her time to work through our Confluence pages - not expecting she'll remember everything, but more to ensure she recalls they exist and what the general contents are.
Anyhow, that's my rant.7 -
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 -
My friend is learning PHP and I told him to install xampp but that fucker went nuts and installed MySQL too which didn't allow the xampp's SQL and ended in conflict.
Oh man that's so funny when non programmers don't do what we say.2 -
Other team lead: Hi DevOps Team, We need you to deploy this app to production. It's maintainers gave up on it in 2019, but we looked at it and it feels right.
Me: Uhm. That's not going to work. It'll fail the security scan before you can even finish the build in CI.
Other team lead: Yeah, this app is the right thing to do, and we needed it last week, but since that won't work, we'll just use this other very very infant technology that was just born yesterday. It's not stable in production, or on MySQL, or in AWS at all, but it's the other direction we can to go.
Me: What problem are you trying to solve in the first place?
Other team lead: Oh, we need access to the read from the production database.2 -
FUCK YOU PHP, FUCK YOU SYMFONY AND DEFINITELY FUCK YOU SHOPWARE.
Don't get me wrong, PHP has evolved a lot, but the stuff people are building with it is just the biggest load of fucking shit I have ever seen: Shopware. Shopware is the most ass-sucking abomination to extend. It's nearly impossible to develop anything beyond "use the standard features and shut the fuck up" that is more sophisticated than a fucking calculator.
The architecture of this pile of crap is the worst bullshit ever. A mix of OOP, randomly making use of non OOP concepts and features together with the unnecessarily HUGE amount of useless interfaces and classes. Sometimes I feel like it's 90% fucking shitty boilerplate shit.
And don't get me started with TWIG. It's a nice thought, but WHY THE BLOODY FUCK WOULD YOU NOT USE VUE IF YOU ARE ALREADY USING IT FOR A DIFFERENT PART OF SHOPWARE. This makes no fucking sense whatsoever and makes development of new features a huge pain in the ass. I can't comprehend how people actually like using this shit.
OH AND THE DATABASE. OH MY FUCKING GOD. This one is bad. Ever tried to figure anything out in a database where random strings (yes MySQL "relational" - you might think) that are stored as text in a JSON format make up some object or relations during runtime?? Why the fuck do you have foreign and primary keys if you don't use them properly??
Seriously you can't even figure out which data belongs to what because the architecture just sucks fucking ass. FUCK YOU Shopware wankers, you suck, your product sucks, your support sucks, your architecture sucks and you keep releasing new versions that regularly break shit even in minor versions.
I used to like PHP, but not in projects like these.6 -
Me: *newly learning MySQL*
Also me: time to buy wedding rings for my pinky finger and the caps lock key16 -
I don't like when client decide which tech use in the project. I got some weird tech request like:
1. Move existing database from postgresql to Hadoop because hadoop is Big Data (is kinda move from amazon rds to amazon s3 just why? have you index, cluster your postgresql table?)
2. Move from mysql to postgresql because mysql cause deadlock (maybe their previous developer just fucking moron)
In this situation we just explain why we don't use that and propose alternative solution. If they insist with their solution either ignore it or decide not continuing the project.5 -
This is the link that has brought me the most joy acceleration in my life.
Go see what it does yourself.
I love adminer so much.
Hyper recommended.
Screw MySQL Workbench.

I was today years old when I created my first node.js Hello World app. I managed to add some basic routing with express.js, managed to read a mysql table and some JSON. I'm starting to 'get' the node.js environment. Shows you're never too old to learn something new.3
-
My phone was stolen so that's why I wasn't getting here to rant about this, but today I had to make a back up and remembered.
adminer's export function doesn't export the tables in the correct order for import. Doesn't take foreign keys into account.
Dude, that's the whole point of a relational database, relations between tables; if you don't take that into account then what's the point?
Is this the same for the rest of database managers or is it just adminer? Please tell me this isn't normal.4 -
Job offer, searching for somebody with (amongst others):
- UI/UX
- React, Angular
- Go
- Azure, Kubernetes, Redis
- Mongo, MySQL
- gRPC
Why do they want to fill 3-4 positions with a single person? I'm afraid I'm only 2 of those people they're searching for.8 -
Hello, fellow developers, i am having a question in mind that confusing me about my career choices.
At first i joined a company as a full stack developer with 6 months experience in MERN, MySql etc.
Now i have completed nearly 1 year in this company but they are always assigning me to full DevOps CI/ CD projects. And i agree i am learning a lot of new things and completed the given works too.
BUT , the question is , should i completely shift as devops engineer or software developer? What might be a better career in long term?
Ps: in CI/CD i did almost all works in Typescript using CDK and sometimes a little bit in python (not good in python but learning)10 -
favourite/recommended database IDEs/tools? I'm looking to put more time into a hobby project using mysqlite. I only got datagrip, mysql workbench and DB Browser for SQLite on my list so far3
