I have to let it out. It's been brewing for years now.
Why does MySQL still exist?
It was lousy as hell 8 years ago, and since then it hasn't changed one bit. Why do people use it?
First off, it doesn't conform to standards, allowing you to aggregate without explicitly grouping, in which case you get god knows what type of shit in there, and then everybody asks why the numbers are so weird.
Second... it's $(CURRENT_YEAR) for fucks sake! This is the time of large data sets and complex requirements from those data sets. Just an hour through SO will show you dozens of poor people trying to do with MySQL what MySQL just can't do because it's stupid.
Recursion? 4 lines in any other large RDBMS, and tough luck in MySQL. So what next? Are you supposed to use Lemograph alongside MySQL just because you don't know that PostgreSQL is free and super fast?
Window functions to mix rows and do neat stuff? Naaah, who the hell needs that, right? Who needs to find the products ordered by the customer with the biggest order anyway? Oh you need that actually? Well you should write 3-4 queries, nest them in an incredibly fucked up way, summon a demon and feed it the first menstrual blood of your virgin daughter.
There used to be some excuses in the past "but but but, shared hosting only has MySQL". Which was wrong by the way. This was true only for big hosting names, and for people who didn't bother searching for alternatives. And now it's even better, since VPS and PaaS solutions are now available at prices lower than shared hosting, which give you better speed, performance and stability than shared hosting ever did.
"But but but Wordpress uses MySQL" - well then kill it! There are other platforms out there, that aren't just outrageously horrible on the inside and outside. Wordpress is crap, and work on it pays crap. Learn Laravel, Symfony, Zend, or even Drupal. You'll be able to create much more value than those shitty Wordpress sites that nobody ever visits or pay money on.
"But but but my client wants some static pages presented beside their online shop" - so why use Wordpress then? Static pages are static pages. Whip up a basic MVC set-up in literally any framework out there, avoid MySQL, include a basic ACL package for that framework, create a controller where you add a CKEditor to edit page content, and stick a nice template from themeforest for that page and be done with that shit! Save the mock-up for later use if you do that stuff often. Or if you're lazy to even do that, then take up Drupal.
But sure, this is going a bit over the scope. I actually don't care where you insert content for your few pages. It can be a JSON file for all I care. But if I catch you doing an e-commerce solution, or anything else than just text storage, on MySQL, I'll literally start re-assessing your ability to think rationally.12
I work for a company that develops a variety of software solutions for companies of varying sizes. The company has three people in charge, and small teams that each worked on a certain project. 9 months ago I joined the company as a junior developer, and coincidentally, we also started working on our biggest project so far - an online platform for buying groceries from a variety of vendors/merchants and having them be delivered to your doorstep on the same day (hadn't been done to this scale in Estonia yet). One of the people from management joined the team working on that. The company that ordered this is coincidentally being run by one of the richest men in Estonia. The platform included both the actual website for customers to use, a logistics system for routing between the merchants, the warehouse, and the customers, as well as a bunch of mobile apps for the couriers, warehouse personnel, etc. It was built on Node.js with Hapi (for the backend stuff), Angular 2 (for all the UIs, including the apps which are run through a WebView wrapper), and PostgreSQL (for the database). The deadline for the MVP we (read: the management) gave them, but we finished it in about 7 months in a team of five.
The hours were insane, from 10 AM to 10 PM if lucky. When we weren't lucky (which was half of the time, if not more), we had to work until anywhere from 12 PM to 3 AM, sometimes even the whole night. The weekends weren't any better, for the majority of the time we had to put in even more extra hours on the weekends. Luckily, we were paid extra for them, but the salary was no way near fair (the majority of the team earned about 1000€/mo after taxes in a country where junior developers usually earn 1500€/month). Also because of the short deadline given to us, we skipped all the important parts like writing tests, doing CI, code reviews, feature branching/PR's, etc. I tried pushing the team and the management to at least write tests and make feature branches/PRs, but the management always told me that there wasn't enough time to coordinate and work on all that, that we'll do that after launching the MVP, etc. We basically just wrote features, tested them by hand, and pushed into the "test" branch which would later get tested and merged into master.
During development, one of the other juniors managed to write the worst kind of Angular code you could imagine - enormous amounts of duplication, no reusable components (every view contained the everything used in the view, so popups and other parts that should logically be reusable were in every view separately), fuck - even the HTML was broken (the most memorable for me were the "table > tr > div > td" ones, but that's barely scratching the surface). He left a few months into the project, and we had to build upon his shit, ever so slightly trying to fix the shit he produced. This could have definitely been avoided if we did code reviews.
A month after launching the MVP for internal testing, the guy working on the logistics system had burned out and left the company (he's earning more than twice the salary he got here, happy for him, he is a great coder and an even better team player). This could have been avoided if this project had been planned better, but I can't really blame them, since it was the first project they had at this scale (even though they had given longer deadlines for projects way smaller than this).
After we finished and launched the MVP, the second guy from management joined, because he saw we needed extra help. Again I tried to push us into investing the time to write tests for the system (because at this point we had created an unstable cluster fuck of a codebase), but again to no avail. The same "no time, just test it manually for now, we'll do that later when we have time" bullshit from management.
Now, a few weeks ago, the third guy from management joined. He saw what a disaster our whole project was. Him joining was simply a blessing from the skies. He started off by writing migrations using sequelize. I talked to him about writing tests and everything, and he actually listened. He told me that I'm gonna be the one writing them, and also talked to the rest of management about it. I was overjoyed. I could actually hear the bitterness in the voices of the rest of management when they told me how to write the tests, what to test, etc. But I didn't give a flying rat's ass, I was hapi.
I was told to start off by writing a smoke test for the whole client flow using Puppeteer. I got even happier, since I was finally able to again learn new things (this stopped at about 4 or 5 months into the project).
I'm using jest as the framework and started writing the tests in TypeScript. Later I found a library called jest-extended, but it didn't have type defs, so I decided to write them and, for the first time in my life, contribute to the open source community.20
Me and co-worker troubleshooting why he can't run the docker container for database.
Me: Check if the port is busy.
Co-worker: To my knowledge, it isn't.
Me: Strange, it just works fine for me and everyone else.
Me: And you're sure you didn't already start it previously?
*We verify that it isn't running*
Me: I'm pretty sure the port is busy from that error message. Try another port.
Co-worker: Already did, it didn't work.
Me: And by any chance restarting your machine won't solve anything?
*It doesn't solve anything*
Me: Alright, I have some work to do, but I'll get back to this. Tell me if you find a solution.
*** Time passes, when I get back he has switched to windows, dualboot, same machine ***
Me: I don't think you'll have a better time running the docker image on windows.
Co-worker: Oh, that's not what I'm looking for. You see, I had a database on my windows partition recently and I thought maybe thats why it won't start.
Me (screaming internally) : WTF ARE YOU STUPID, WINDOWS AND LINUX ISNT RUNNING AT THE SAME FUCKING TIME.
Me (actually saying): I don't think computers work like that.
Co-worker: My computer is magical. It does strange things.
Me: That's a logical conclusion.
*** More time passes ***
Co-worker solves the problem. The port was busy because Ubuntu was already running PostgreSQL on that port.
Third co-worker shimes in: Oh yeah, I had the exact same problem and it took me a long time to solve it.
Everyone is sitting in arms reach of each other.
So not only was I right from the start. Someone else heard this whole conversation and didn't chime in with his solution. And the troubleshooting step of booting into windows and looking if a database is running there ???? Wtf
Why was I put on this Earth?7
I just can't understand what will lead an so called Software Company, that provides for my local government by the way, to use an cloud sever (AWS ec2 instance) like it were an bare metal machine.
They have it working, non-stop, for over 4 years or so. Just one instance. Running MySQL, PostgreSQL, Apache, PHP and an f* Tomcat server with no less than 10 HUGE apps deployed. I just can't believe this instance is still up.
By the way, they don't do backups, most of the data is on the ephemeral storage, they use just one private key for every dev, no CI, no testing. Deployment are nightmares using scp to upload the .war...
But still, they are running several several apps for things like registering citizen complaints that comes in by hot lines. The system is incredibly slow as they use just hibernate without query optimizations to lookup and search things (n+1 query problems).
They didn't even bother to get a proper domain. They use an IP address and expose the port for tomcat directly. No reverse proxy here! (No ssl too)
I've been out of this company for two years now, it was my first work as a developer, but they needed help for an app that I worked on during my time there. I was really surprised to see that everything still the same. Even the old private key that they emailed me (?!?!?!?!) back then still worked. All the passwords still the same too.
I have some good rants from the time I was there, and about the general level of the developers in my region. But I'll leave them for later!
Is it just me or this whole shit is crazy af?3
Management eats shit for breakfast
I am the sole Dev on a project.
Stack: Postgresql, redis, nginx,Java with Spring Boot, Neo4j.
I am the only one nearly familiar with : Redis, Neo4j and anything Java.
I'm gonna be on vacation for the next 15 days since they have told me that we where gonna be on a "testing/feedback" period.
My vacation was approved.
Today's meeting: we have a URGENT deadline to meet some criteria that might be the difference between have further investment or not.
Urgent deadline: last day of my vacation.
My face: poker

This might be the most ambitious project I've ever started up till now, teaching my girlfriend everything college isn't.
As some of you may know my uni isn't the greatest and lacks in professor quality, my girlfriend (who's taking the same bachelor) knows this and when she knew I was starting a new little side project she wanted in.
At first I was skeptical, this could be just an excuse to spend more time with me, so I told her:
"if you really want to then I'm all for it, it'll be done my way and the first few weeks will be tough, however I promise by the end of it you will know 10x what you do now"
She agreed and so our journey began 3 weeks ago, my goal: make a kick ass project, do it in record time and teach her enough to cope with a IRL job.
I've setup the project so by the end of it she is well versed in the following: scrum, Django, MVC, python, HTML + CSS3, git, GitHub, PostgreSQL and Docker. In about 4 to 6 months.
We are into our third sprint this week, she had two small breakdowns because she couldn't believe how much she was missing out and felt she lacked talent, this is our third week and I'm glad to see that she's actually enjoying herself.2
Never be afraid to ask questions and look stupid.

Those who don't - remain stupid.
Why does bit(128) in PostgreSQL take up 21 bytes of storage?3
My resolution for this year:
- learn PHP
- be a pro with SQL and learn PostgreSQL
- build couple cool hardware projects with Raspberry Pi and Arduino based on C.5
New dev prefers mariadb over postgresql, which is okay.
But his main reason is 'the smaller docker image'
What an argument, wtf2
Got asked into a meeting to give my opinions on the security about software that might be used to implement a web app.
After 20 minutes of listening to bullshit that wasn't even my concern they got into databases and I was constantly talked down, by people who know shit about tech, about the professional use of PostgreSQL and they only did shut the fuck up when I compared their "important business" to Facebook using MySQL.
Come on... Stop talking down about shit you know nothing about.3
Manager: let's use elasticsearch for performing relational queries. PostgreSQL performance is not great.
Me: Say what? 👿4
Trying to connect PostgreSQL with java. After one hour still no idea how.
Trying to connect MySQL with java. Five minutes.
I have spent the last 24 hours trying to connect a postgres db and a docker contained application both running on the same vps.
What no one told me was docker applications run on a separate network interface…
I need sleep...5
Oh man where to start:
Not wanting to use LINQ because he did not wanted to "download external dependencies"
Not wanting to use prepared statements on their php sql code, and refusing to use pdo because they will "always use mysql"(moved to postgreSQL shortly after I left)
For some reason including a php file that only had ?>......thats it....only ?>
Use c++ but refused to learn oop and use structs for everything, importing stdio.h and printf everything.....like really?
Maybe just nitpicking, but refusing to use the recyclerview pattern on am android app. The implementation was faster after I made the change.
Importing a library for promises instead of using the ones already in the language(JS)
Changing the style of aaaaall p tags instead of using classes as well as refusing to use divs in place of p tags...well...fuck
Not indent his ASP classic code
Use notepad on his asp classic code
Use ASP Classic in 2017, even for new projects6
I hate SQL Server so much, don't matter how Microsoft say they improve themselves at SQL Server.
There's a lot of fucking bloat, messes your system and your services, adds tons of crap in your system registry, while more advanced SQL engines such MariaDB/PostgreSQL are more contained, and its very small.
Why SQL Server has to mess with Windows' ACL and his own privilege systems?.
Uninstall it and a lot of components remain hidden and tons of registry entries, not even TotalUninstaller or CCleaner can help.
I hate it since my technical high school and my goddamn college is forcing us to use SQL Sever for EVERYTHING, instead of good alternatives, messed my computer entirely requiring to format.
I try always to convince my freelance clients to use open-source alternatives, and say how SQL Server is so crap, (i had variant degrees of success).14
Yesterday I had a good idea for a project I'm working on, so I decided to stay awake all the night drinking RedBull in order to implement it.
Eventually I went to bed. I dreamed I was on an island with some friends and a volcano erupted. We escaped from the lava boarding on a big boat, then a tsunami wave reached the boat. Boat didn’t sink, however electric power went down. When the electric power returned, on the boat screens appeared the following text: "Please, restart MySQL". However, under it there was the PostgreSQL elephant logo. I was someway more worried about that rather than the tsunami. After that, a hurricane was coming too. We were saved by people coming with a spaceship, however they appeared to be drunk. I woke up thinking «WTF!».
This morning my husband told me our 4 cats made fuss all the night.1
Little job story about dev server cleanup :-)
Ops 1: We are running out of disk space on <server ip>, only 14GB left
[one day later]
Chef: Guys can you take a look at the server, I see postgresql is taking 51GB
[a few minutes later]
Ops 2: otherwise we can truncate the whole database
*Dev 1, 2, 3, 4* D: !!!!!
Dev 1, 2, 3, 4: ok we are looking at it
[few seconds later]
Dev 2: I cleaned 13GB, more can be cleaned if we do a backup
Dev 3: I also cleaned a few gigs2
Just learned that yesterday someone suggested putting the dev team on "workspace", when I was on leave.
My first question, "what the hell is workspace?"
"It's a remote environment..."
Okay I get it. Are you kidding me? Doing development on remote desktop?
My second question, "Why the hell did someone suggest that?"
"We have had issues with devs using MySQL but the target prod will be using PostgreSQL. That caused issues, inconsistencies... And we found some issues after deployment."
Okay so much for DB agnostic. I called it out that everyone now install PostgreSQL on local. Problem solved, hopefully.
Why we had MySQL in the first place? Yes DB agnostic is one of the reason. The other being I'm more familiar with MySQL so it's quicker to perform tasks (like "can you clone that environment for me" and "can you fix the data on XYZ"). But that's trivial.
Just some ridiculous suggestion that set me off.7
Just started an internship at a well put-together startup and ended up being in charge of project management as well. Having so much fun learning to be more independent and be a likeable manager. The tech stack in the tag.3
I used to work with a teacher in my last uni year.
The job consisted on doing a kinda-like management system for a business. It all began kinda "right", we agreed upon a price for 6 months of my work (a very lowball price, but it was just right because I was learning stuff that we were going to be using).
Fast-forward first six months, all I do is code frontend, mockup screens and whatsoever because this "business" hadn't give us proper requirements (Yeah, I told him to ask for them, but nothing came through).
So I was like well, I'll keep working in this project because I really want to finish it. Sidenote: I was doing all the "hard work", he didn't know how to code, and he calls himself a teacher... wtf).
Months go by, and a year goes round, in between these months, he spoke to me, that he wanted me that we kept working together, that we could renegotiate the payment (I asked him to give me my payment once the job was done). I agreed, but my uni residence period was coming along and I got an oportunity to go abroad to another country.
So there I was, in the need of money to buy my passport, plane tickets and other stuff, so I asked him for the payment.
Needs to be noted, that the last 6 months work was me doing tutorials on how to fucking use Linux, how to use PostgreSQL, how to fucking use CSS! He told me he would pay me extra for it.
The day came, and I received my payment... the exact amount we talked a year ago, I was like "Seriously dude?", but well, I needed the money and I didn't have time to argue, so we talked a little bit about me helping him and I told him "As long as I have time, I'll help, but remember that I'm going abroad to work for a small startup, so maybe I'll be up to my head with work" he agreed, we nod and then I left.
First week abroad came in and I was doing a shit-ton of stuff, then his first message comes around "Hey, I need more tutorials! ASAP! Before 6PM"
What.The.Fuck. I told you, son of a bitch, that I wouldn't be able to do them until weekend.. and it was monday!
So I ignored it, weeks went throught and my "angry mood" was fading away so I said to myself "Well, it's time to pick up that stuff again", I open Slack and I find a week old message with a document attached, it was a "letter", I just skimmed by it and read some keywords "deceptioned... failed me.."
Sure dude? Was I the failure? Becase, as far as I remember, you were the fucktard that didn't know how to fucking install a VM!
A week went by, and then randomly a friend of mine talks to me through Facebook:
E: Hey, how are you?
M: I'm fine, what's up?
E: What did you do to TEACHER?
M: Nothing, <explains all situation>
E: Well, It seems weird, that's why I wanted to talk with you, I believe in you, because I know you well, but TEACHER it's thrashing shit about you with all his students on all of his classes
E: Yeah, he's saying that you are a failure, irresponsible, that you scammed him
That moment, I for sure, lost all moral responsibility with him and thought to myself "He can go fuck himself with my master branch on his ass"
So when I got back to my country, I had to go around in school, avoiding him, not because I was ashamed nor anything by the way, just because I knew that If i ever had the disgrace to meet him face to face, my fists would be deep into his nose before he could say "Hey".
Moral of the story:
If you overheard that a teacher has a bad rep, not by one, nor two, but more than +100 people, maybe it's true.
Good thing my friends and others know me well and I didn't have repercutions on my social status, I'm just the guy that "fucked up TEACHER because I had the right and way to do it"4
This year I want to start a project that I'll be proud of, learn PHP, Java, PostgreSQL and Assembly.22

On the beginning of a project I'm not yet ( 😒 ) taking part of I questioned the use of firebase because I understood the client was gonna ask for the web app to be hosted on their servers lately, but people told me not to worry.
Today... Only 2 fucking months later they are asking for the specifications/technologies used so they can prepare their server to host it and I was laughing my ass out internally while saying to my boss:
Well, looks like you are gonna need to rewrite huge parts and probably write a back end from scratch if you are gonna use postgresql.
Lol, why do people never listen to me? This is becoming ridiculous....
But i have studied databases for a few weeks and i have been thrown into the backend.
Java - spring boot - myBatis - postgreSQL.
Its a big change to my react world.
And its fucking amazing.
You know what's a good place for init Files? A standardized place...
A place, where one would expect it...

Never ever trust a backup that you didn't!
I know, I should backed up all by myself, but a trusted on a colleague and now there is not database ... The server was formated :-(
Damm, all backups are incomplete by a bad script ...2
If you ever want to make a LAMP stack developer cry, just tell him he's got to work with NGINX and PostgreSQL.13
I've now spent 6 hours trying to find a way to do something similar, as you can do in Neo4j, where you find relations up to depth 5, in PostgreSQL.
The issue is, I have to tables. One with persons, another one with relations (incoming ID and outgoing ID) to have a many to many relationship.
I'm at the point where I just don't care getting it to work. In Neo4j it's a fucking one liner, so why the fuck am I getting assigned to do this in PostgreSQL?
To prove a point? Well fuck you, I'm done with this shit.5
Client: "According to the Postgresql Version Support Policy, 9.3 will be expired by September 2018. That's only a few months away."
Me in thought: "Expired? Like a rotten egg? With an expiration date? OK, chill. His English isn't that good. Maybe he meant that support expires since its EOL."
Client: "We need to upgrade so that we can continue using the database."
Me in thought: "Yeah, he really meant "expired" in database too."4
Most exited I've been about some code? Probably for some random "build a twitter clone with Rails" tutorial I found online.
I've been working on my CS degree for a while (theoretical CS) but I really wanted to mess with something a bit more practical. I had almost none web dev experience, since I've been programming mostly OS-related stuff till then (C). I started looking around, trying to find a stack that's easy to learn since my time was limited- I still had to finish with my degree.
I played around with many languages and frameworks for a week or two. Decided to go with Ruby/Rails and built a small twitter clone blindly following a tutorial I found online and WAS I FUCKING EXITED for my small but handmade twitter clone had come to life. Coming from a C background, Ruby was weird and felt like a toy language but I fell in love.
The next few months were spent studying and working on my project. It was hard. I had no experience on any web dev technology so I had learn so many new things all at once. Picked up React, ditched it and rewrote the front end with Vue. Read about TDD, worked with PostgreSQL, Redis and a dozen third party APIs, bought a vps and deployed everything from scratch. Played it with node and some machine learning with python.
Long story short, one year and about 30 books later, my project is up and running, has about 4k active monthly users, is making a profit and is steadily growing. If everything goes well, next week I'll close a deal with a pretty big client and I CANT BE FKING HAPPIER AND MORE EXCITED :D Towards the end of the month I'll also be interviewed for a web dev position.
That stupid twitter clone tutorial made me excited enough to start messing with web technologies. Thank you stupid twitter clone tutorial, a part of my heart will be yours forever.2
Does anyone knows about OLAP cubes, Rollups and whatsoever?
I'm wondering if this query it's overcomplicated...
Just trying to achieve a sum of amounts by month on a year lapse6
It has finally happened. I have escaped the land of bloated Objective-C and JabbaScript. This week I have started on another project, a full stack team working in Angular, Java, Hibernate, PostgreSQL. The dream has come true. Java it has been too long my friend.
Puts three months of work into this project; cronjob to ping 3 APIs at regular intervals, cleans, massive features extraction, dumps into PostgreSQL db. Got Django on top of that with a small neural net and interesting viz - absolutely gorgeous!
Can’t fuckin wait to showcase that.
Feedback: “is that the right blue? I think you have the old company logo! etc”
Excel plus CSV into word with mail merge into outlook to send.
I wanted to do it the hard way.
Postgresql database + python script.
I have no idea what I'm doing, but isn't that the best way to learn?1
I some time's feel stupid when my Ubuntu start acting up on prod, purge this and that ,fuck apache can't start system CTL that ps ax grep in the p#$#@* , damn apt install nginx full good, mysql can't start too ,OK apt install mariadb-client else percona && apt postgresql thanks ,god no client noticed ..3
When people design a brand new Postgresql schema (case sensitive) using a mix of upper and lower case letters.
Only to then proceed and escape every single table and column name in every single query.1
I was discussing scope and budget with a potential client for a side project. It involved a good bit of complex postgresql and subsequent aggregations and creation of reports. He was hiring because the last guy's work was so poorly documented, they couldn't verify its accuracy.
Me: "So, what are your thoughts on a budget?"
Him: "We were thinking something like $15/hour."
Me: "Um...ok. If I can ask, where did you get that number?"
Him: "That's what we paid the last guy."
I've been given a huge stack of paper, some users stories and loose specs. Was tasked with engineering the specific requirements, then the models and finally the database. Then I need to build an API on top of that.
Stuff I'll use is Go and Postgresql. Small issue is, I've never done DBs, so I've no idea what to do or where to start.
Does anyone have any resources to help kick-start myself in this field? I've been reading on SQL, but that doesn't really tell me anything about data structures and how to transform those user stories into product requirements.6
I was just trying to learn Ruby by watching a YouTube channel, when the instructor use that example 😂😂 I bet this app will "blow"3
Exclusive Locks in postgresql are the real life manifestation of Satan ! Especially when you can't determine what's the cause. I hate my life. I hate this friday. I hate my family. I hate everything.1

Ever find something that's just faster than something else, but when you try to break it down and analyze it, you can't find out why?
I decided I'd test it with a typical discord bot-style workload (decoding a JSON theoretically from an API, checking if it contains stuff, format and then returning it). It was... 1.73x the speed of python.
(Though, granted, this code is more network dependent than anything else.)
Mean +- std dev: [kitsu-python] 62.4 us +- 2.7 us -> [kitsu-pypy] 36.1 us +- 9.2 us: 1.73x faster (-42%)
Me: Whoa, how?!
So, I proceed to write microbenches for every step. Except the JSON decoding, (1.7x faster was at least twice as slow (in one case, one hundred times slower) when tested individually.
The combination of them was faster. Huh.
By this point, I was all "sign me up!", but... asyncpg (the only sane PostgreSQL driver for python IMO, using prepared statements by default and such) has some of it's functionality written in C, for performance reasons. Not Cython, actual C that links to CPython. That means no PyPy support.
I've always found it funny when sql errors "at or near" a character. I don't know enough about sql to understand why it does that (although I'm sure there a reason!)....but it just sounds like it's not trying hard enough 😂
Maybe someone smarter can explain?1
Plans for 2019 are to release two products.
1. A text-based strategy game engine that will act as the core of two or more progressive web applications, using Node.js/Express, EJS, and SCSS. It will be proprietary, subscription-based, and playable 24/7 online or offline as a web site or mobile app with nightly/weekly/monthly events and items (think KoL, on steroids, with butter on top.)
I am currently undecided whether to go with MongoDB, MySQL or PostgreSQL, so any feedback - without derailing the other choices, and understanding that it needs to be minimal at first with the ability to expand to millions of users - would be appreciated.
2. I'm sculpting collectors figurines of guinea pigs, molding, casting and then selling a limited set that are hand-painted by me with a certificate of authenticity, as well as marketing blank versions of each with a choice of three colors (including white, and either red or black for eyes - a total of five) for people to either paint by themselves, family members, or friends.
This will also have a website that allows you to choose the breed and colors (changing the picture according to your choices), as well as allowing people to use it as a social media outlet - as if their own guinea pigs had profiles instead of humans. It's also planned to support rescues worldwide and educate folks about properly caring for cavies.5
I actually learnt this last year but here I go in case someone else steps into this shit.
Being a remote work team, every other colleague of mine had some kind of OS X device but I was working this Ubuntu machine.
Turns out we were testing some Ruby time objects up to a nanosecond precision (I think that's the language defaults since no further specification was given) and all tests were green in everyone's machine except mine. I always had some kind of inconsistency between times.
After not few hours of debugging and beating any hard enough surface with our heads, we discovered this: Ruby's time precision is up to nanoseconds on Linux (but just us on OS X) indeed but when we stored that into PostgreSQL (its time precision is up to microseconds) and retrieved it back it had already got its precision cut down; hence, when compared with a non processed value there was a difference. THIS JUST DOES NOT HAPPEN IN OS X.
We ended up relying on microseconds. You know, the production application runs on Ubuntu too. Fuck this shit.
Hope it helps :)
P.s.: I'm talking about default configs, if anyone knows another workaround to this or why is this the case please share.
Returning back to the C# with NET Core was a mistake.
Currently working on a simple web project and I'm already stuck with the simplest problem: cannot connect to the local PostgreSQL instance.
"Cannot resolve host", bull-fucking-shit, localhost is not resolvable, 127.0.0.1 is not resolvable.
Better enough, tried to run Dns.GetHostEntry (which failed from the stack trace) on same localhost and... It's working... Why it's not working on the fucking Npgsql, why it's not working in the lib.
Now I totally understand that I don't get Microsoft's way of solving problems.14
Rails, React, React-Native, Docker, Kubernetes, Openstack, Jenkins, AWS, Microservices, Realm, MongoDB, PostgresQL, GraphQL (list goes on...), and I'm not even done yet.
6 months was spent learning all of the above because I found a Rails-only monolith on Heroku unsettling. My first batch of containers was just deployed and I couldn't be happier. Love my job.3
Does anyone have any experience with postgreSQL? I come from a heavy SQL server background and am thinking of learning postgreSQL. What is it like, more specifically compering it to SQL server.
Postgresql kept shutting down at odd times. Then it became predictable. I googled, went through mailing lists, archives, old threads, Stack overflow, friends, family, my bosses, my old colleagues, forums, chat groups and paid redhat support.
Apparently, I'm the only one and the first on this planet to have this problem. And it's scary.6
After 4 1/2 hours of testing I have redeployed my postgresql database from Windows to Debian Server. I can now access my database and deploy webapps from any computer, anywhere, anytime.
It's 2:30 AM in the morning. I am exhausted but fulfilled.1
Maybe noob question here, but what's the added value of using graph db like neo4js compared to regular RDBMS like PostgreSQL ? I see our beloved devrant uses neo4js so I am wondering if it's worth spending some time digging into this, just that (ok, actually it would be too cool to also have dfox and trogus appear in comments notifications)5
We did what any person that searches for a dirty solution would do.
We saved the result of a query in a file and load the file when we need it.
The most I have worked on something is 14 hours. It was for a university project, that involved creating a "banking" app that was intended to demonstrate the use of an SQL database. I had a partner, and we had done nothing about the project until the previous day. We started working at 5 PM and the demonstration was at 12 PM (noon) in the next day. We used PostgreSQL for the database, and C# and Windows forms for the GUI. My partner took on the database creation and I took on the GUI. I had minimal experience with C# and had never worked with Windows forms or DB bridging in a program. On top of it, lack of sleep hits me really hard, so by midnight I was just like a zombie with near zero focus capacity. As a result, I ended up rewriting numerous components with identical logic and appearance and some different elements that could be parameterized, simply because organizing my thoughts to write proper code was out of the question in my condition. The writing, debugging, testing and packing of the project ended at 7 AM, the morning of demonstration. I slept for 3 hours and then met with my partner and headed to uni. I never left a project for the last moment again. We ended up taking a 9/10 grade.1
Today I tried to call a Python module I developed from PostGreSql. Well after a whole day spent on that, fuck you PSQL!
where the fuck is the fucking transaction log of postgres???????????????????
I WANT A FUCKING TRANSACTION LOG
no queries that output stuff ... i want a transaction log, a fucking transaction log3
I don't know what to think about this.
Postgres' jsonb on a raspberry like SBC is still much faster than mongodb on an 8 core x86.
Had to do a school project with PostgreSQL and absoluted hated it.
>>fast foward 5 months>>
New job, new project. After one week of trying to connect to a local database with MySql, Xammp and Wampp without sucess guess wich database worked...
We are now best friends.
Handy postgres script for those on teams with folks who maybe don't write the best queries...
`SELECT pg_terminate_backend(pid) FROM pg_catalog.pg_stat_activity WHERE query_start < now() - interval '3 minutes'`
PHP: Laravel, Phalcon, Composer
Python: Django, Flask, Requests, pip, SQLAlchemy
Java: Spring, Dropwizard, Hibernate
DB: MySQL, MariaDB, PostgreSQL, Cassandra1
I have technical problems with postgresql, AlienVault, Xenservers and Fortigate. I should be reading manuals and going through forums and mailing lists but instead, I'm reading ebooks in personal development like time management, verbal communications improvement and personal finance.
What is wrong with me?1
Any Linux Kernel developer?
I was thinking about a SELinux module to insert AVC in a DB like PostgreSQL or just a simple SQLite 🤔1
Yesterday evening: committed my day's work to git. Tested everything and it all worked like a charm apart from a bug in my seeder I intended to fix today.
Today: failed to fix the error for 6 hours. Decided to go back to my commit from the day before only to discover now even my migrations won't work anymore.
Ready to smash my laptop
I had to start over learning SQL when I faced the JSON functions of PostgreSQL during a try and error period to get nested json_agg in one query.. I'am too old for that low level stuff! 🤨
Hello All, Could you give advise please? I choosing a database for my new Joomla site. Is it better to use PostgreSQL than MySQL for my site? As I could understand PostgreSQL is more stable and safe database And the speed of PostgreSQL comparable with MySQL.9
A music player/library with a postgresql database and an HTML interface (a bit like cherrymusic). Written in Python, it started to be big.
How is it that years of development are not enough for NewRelic to add native support of mssql metrics in their unholy newrelic nodejs agent.????!?!?11!
On the other hand "important" databases like PostgreSQL are having native support.
Excuse me... WTF!!!!2
Help needed: i need the st_distance_sphere function from PostgreSQL, but I only have MariaDB 10.1.21
Question: - can/should i Switch to Postgresql (i do only Basic inserts and selects from PHP PDO)
- has anybody an idea for a workaround (i'm Not very familiar With SQL-functions, so please explain :) )
Thanks a lot 👍3
Thoughts on Apache Cassandra? Seems awesome, but are there any gotchas we should know about before diving in? Currently we use Postgresql for most things.3
Have you used Postgresql with EF Core code first? My migrations don't run. It says in correct syntax near GENERATE. I don't know if this is a bug or I'm doing something stupid5
Elixir, Phoenix, PostgreSQL, GraphQL, ReactJS and Redux.
Anything missing on this stack to be perfect? 🤔6
Just installed and started playing with DataGrip.
It feels pretty solid with the little bit of Postgres I have been using it for.
I would expect nothing less from JetBrains1
