"Don't deploy on Friday" is a public admittance that your company either has no CI/CD pipeline, or that all your devs are retarded rhesus monkeys who only wipe their ass if the product manager wrote it as a spec.

If the saying was: "Don't port your whole API to GraphQL on a Friday", or "Don't switch from MySQL to Postgres on a Friday", I would agree.

But you should be able to do simple deploys all the time.

I deployed on Christmas & New Year's eve. I've deployed code while high on LSD, drunk-peeing 2 liters of beer against a tree after a party. I've deployed code from the hospital while my foot was being stitched up. On average, we deploy our main codebase about 194 times a week.

If you can't trust your deploys, maybe instead of posting stupid memes about not deploying on Fridays, you should fix your testing & QA procedures.

My friend just made an awkward joke

Me: I couldn't get Postgres working on ubuntu

Friend: How bout installing GET-gres

Me: (awkward silence)

I'm 54 y.o.

I think I'm completely outdated in my skill, as in the last 14 years, I worked on a specific business problem, with an old technology: a JSP application + javascript + postgres.

I do understand software development, agile, web application development, linux server, basic/moderate AWS skills, etc.

Now they laid me off instead of including me in the evolution of version 2 of the software. Maybe covid, company had almost no cash-flow. Well they have now...So basically they fired me to find money to rewrite the application.

I feel without hope at my age.
I'm a generalist.
I can understand fairly well everything you'll throw at me, reactnative, angular, nosql, python, but I have little first-hand experience.

I don't have a lot of management skills, even if I've given frequent presentations to C-roles and board, and I implemented a whole agile methodology in my team.

I don't know what to do.
The amount of technology to study is huge nowadays. When I was younger I could get away with some php and java.

Full-stack developer is a big word for me. Maybe I could handle a full stack web application, but not from scratch.

I feel at my age, I'll compete with 20-something guys with better skills and lower salary requests.
I don't think I can pull a night anymore.

I'm trying to shoot high to management positions with no much success.
I'd like to go on developing, I know that there are 50-something developer out there, but who managed to find a new position at 55? at 60?

As soon as I finish the few money I spared, I'll be on the street, I'l be the "website for food" guy.

Rage..

Boss: 'I've got a PowerPoint presentation with 45 charts in it. Oh, and a huge excel sheet with the data for it. Please build some of the charts in our own software, with the given data.'

Easy, I thought.
Yea, thanks to the person that gave my boss the data.. The half of the important columns were removed (privacy stuff).
And.. Excel? Oh, and his calculations are nowhere documented nor consistent.

I converted excel to postgres, easy.
It took me 2 hours to fkn research what he calculated in one line chart, just to implement it in like 10 minutes.
2 hours, man I could made awesome stuff in that time!

I guess I should write this in CAPSLOCK to make it more interesting. I'm just raging in my head 😂

Never gonna happen:

* Port our API to graphql. Or even make it just vaguely rest-compliant. Or even just vaguely consistent.
* Migrate from mysql to postgres. Or any sane database.
* Switch codebase from PHP to... well, anything else.
* Teach coworkers to not commit passwords, API keys, etc.
* Teach coworkers to write serious commit messages instead of emoji spam
* Get a silent work environment.
* Get my office to serve better snacks than fermented quinoa spinach bars and raw goat milk kale smoothies
* Find an open source IDE with good framework magic support. Jetbrains, I'll give you my left testicle if you join the light side of the force.
* Buy 2x3 equally sized displays. I'm using 6, but they're various sizes/resolutions.
* Master Rust.
* Finish building my house. I completely replaced the roof, but still have to dig out a cellar (to hide my dead coworkers).
* Repair/replace the foundation of my house (I think Rust is easier)
* Get slim and muscular.

Realistically:

* Get a comfortable salary increase, focus more on platform infrastructure, data design, coaching
* Get fat(ter). Eating, sitting, gaming, coding and sleeping are my hobbies after all.
* Save up for the inevitable mental breakdown-induced retirement.

I can maintain your shitty legacy node 6 code
And the shitty m3 ec2 instance with Ubuntu 16 that it runs on
And another one with postgres 9
But if I have to make a powerpoint presentation, I am jumping ship.
A man has his limits

Who killed MySQL?? Your guesses... Was it Ruby, a fan of postgres? 😂

Just generated a postgres (postgis) database of 456gb. Need to copy it to my own pc....

*tries scp'ing*.........*10mbs*.........................
*alright, lets try this with rsync*....*10-20mbs*......
.
.
*compresses the entire database into a 241gb file*
*moves the file to the root of the webserver*
*starts downloading with axel*.....

108mbs!

Those tiny 'hacks' can be fun.

10 years ago, I found a vulnerability in the connection between an insurer I was working for, and the network of databases of municipalities. I was only a hacker in so far as kids who watched Hak5 are considered hackers, so I always carried this laptop with a fake access point, package sniffer, wep crack, sslstrip, etc with me.

The vulnerabilities allowed me to register a new identity, for which I requested a passport.

Walking up to the town hall desk with two passports with different names, both mine, was pretty cool.

I did not do anything malicious, and was hired to fix the issues (wep encryption on insurers trusted wifi, and municipality postgres gave write access to all third parties)

For a few days I was the coolest kid in school though!

I'm looking for a new job.
If anyone is hiring remotely or knows of somewhere that is, could you please let me know? 😊

Summary: Burnout, and everything's broken.

I don't feel like doing a damn thing today. I look at the code and cringe. I look at Slack and think "ugh. i can't." Mental capitals are even too much work.

(I've started reading "Zen and the Art of Motorcycle Maintenance" to try and combat burnout. I'll write a rant/story about it here if I find it helpful. but all I want to do today is drink tea and read.)

But onto the story:

Heroku is deprecating support for and will automatically upgrade any old verisons of Postgres running on its platform after August something (like five days from now).

I performed the upgrade to PG10 on Sunday (and late into the night), provisioning a new follower, blah blah blah.

However, the version of Rails we're using (4.2.x) doesn't support PG10 sequences, so I manually added in support via a monkeypatch. I did this on our QA servers first, obviously, and everything worked as expected. After half a day of no issues, I did the same on production, and again: everything worked as expected.

But today? I keep hearing about new things that are broken. One specific type of alert doesn't work for one specific person (wat). Can't send [redacted] at all. Can't update merchants! Yet there are magically no errors logged.

That last one (well, two) are just great; let me explain: when there's an error concerning merchants, the error gets caught, isn't logged or recorded anywhere so it just disappears, and the rescue block triggers a json response instead and happily exits. This is for an internal admin tool, so returning a user-friendly error is kinda stupid anyway, but masking what actually happened? fuck that dev with an obelisk made from spikes and solidified pain. That json response is also lovely: it's a 200 OK returning {status: 1, data: "[generic message containing incorrect IT jargon]"}. Doesn't even say "error" anywhere. Bloody everything about this pattern is absolutely wrong. Even the friggin' text.

Fucking hell. I want to pipe the entire codebase into shred and walk out the door.

But I digress. So many things are broken, my motivation is wanning to a sliver, and I have a conference call today where I'll undoubtedly be asked why everything is on smoking and/or on fire, and my huge and overly productive week last week will ofc mean nothing by contrast.

Ugh.

`shred ~/dev/work -zfu -n 32 &; ./brew tea --hot && wine ~/takeabreak.exe`

First of all, I hate crammers so much. These people kill the industry without even understanding it. They turned interviews into exams, missed the point of hiring, and saw no distinction between knowledge and information all the time. They don't understand that if you can google an answer in five seconds, it's not knowledge. It's information.

They don't understand that questions like 'what will Python do if you delete an item from a dict while iterating over it' are complete nonsense. They don't understand that it's not 'dig deep'; it's just a bad practice that leads to errors, thus must be avoided. The fact of remembering 'RuntimeError: dictionary changed size during iteration' means that you haven't been avoiding it enough.

One more example. Which signature is correct?
- ApplicationListener<ContextRefreshedEvent>
- ApplicationListener<ContextRefreshEvent>
- ApplicationListener<RefreshedEvent>
- ApplicationListener<RefreshEvent>

Second. What's the point of forcing you to write compilable code in google docs? Do they really expect that one could possibly remember 'import org.springframework.beans.factory.annotation.Autowired;'? Seriously?

Third. Why do they expect me to know Spark, Java, J2EE, Spring Boot, Python, Kafka, Postgres, React/Redux, TypeScript, and work for miserable 70K EUR?

What's wrong with the European IT job market? Are they fucking nuts?

My tech stack progression:

Started with PHP without any frameworks, using a homegrown MVC architecture. Used to use `mysql_` functions everywhere. And only jquery + vanilla CSS in the front end.

Then moved to use PDO functions in PHP and Backbone.js + Less CSS in the front-end.

Then moved to Django in the back-end. Did not like Django very much as it is too opinionated and not flexible (although it's damn good for rapid development if you buy into their type of things).

Then moved to Flask + SQLAlchemy and using a home grown architecture. This is a sweet spot for me in terms of back end and stayed in this spot for the longest time.

Moved to Postgres from MySQL as I fell in love with Postgres.

Then learnt React+Redux. Liked it. Made most sense to front-end development this way. Moved front-end stack to React+Redux.

Learning Haskell and been working with Scotty and eyeing Servant for a while now.

Let's see where it goes from here.

PS: this is my personal journey through various tech stacks in various products at various companies I have worked. I'm not talking about moving a product through these many tech stacks. That doesn't make any sense.

PORTFOLIO INFLATION

when every junior is writing algorithms, the next step up, the only way to keep up is writing apps. When every junior is writing apps, the next leg up is writing an entire SN.

Eventually junior full stack devs are writing microservice streaming cloud backend content delivery optimized social networks wrapped in virtualization with load balancing, proper CI, public accessible analytics apis, written in custom webaseembly compiled scripting backend utilizing both the latest graphql and every single feature of postgres, while also being a web site builder, an in browser app, mobile optimized, designed to transmogrify your asset pipelines linearflow functional-oriented modular rust cratified turbencabulator while cooking your turducken with CPU cycles, diffusing your gpt, and finetunning your llama 69 trillion parameter AI model to jerk you off all at the same time.

And then the title "wizard" becomes a reality as the void of meaning in our lives occupied by the anxiety of trying to reduce the fear of rejection in job hunting, is subsumed by the brief accidental glance into the cthulian madness-inducing yawning abyss of the future which is all the rest of our lives we have to endure existing for until at last sweet sweet death consumes us and we go to annihilation never having to configure one more framework or devops deploy of another virtual environment.

And it dawns on us that we no longer develop or write code at all. No, everything has become a "service" in this new hellscape future. We slowly come to the realization that every job is really just Costco greeter, or eventually going to be reduced to something equivalent, all human creativity, free will and emotions now taken care of by the automation while we manage the human aspects, like sardines pushing against one another not realizing their doom has been sealed along with the airless can they have been packed into, to be suffocated by circumstance and a system designed to reduce everything to a competition of metrics designed by the devil, if the metrics were misery", and "torture", while we ourselves are driven by this ratfuck wheel to turn endlessly toward social cannibalism, like rats eating their babies, but for the amusement of wallstreet corporate welfare whores who couldnt turn a dime if it wasnt already stolen.

And on our gravestones, those immortal words are carved, by the last person who gave up the ghost, the last whose soul wasnt yey shovelled onto the coal fires driving the content machine consuming the world:

Welcome to costco. I love you.

That moment that you finally have a functioning goddamn application and then you notice that the queries (Postgis) are so fucking heavy (one percent load up when executing about 5 simultaneously) that you start to wonder how you'll ever run this in production...

I know jack shit about Postgres/Postgis, this is going to be fun 😐

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.

Forgot to close() connection to the postgres and opening the new connection was inside of the query loop... So I successfully overfilled all the possibie 100 connections to 5 dbs out of 6. I have no direct access to them so I cant delete them. I'm still on probation and I have to go to lead dev and tell him that I messed up...

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...

Can someone explain the pricing for DO, AWS, or any other cheap hosting? DO $15 bucks for 1 database or multiple database in one server? AWS S3 or E2? Or should I stick with Heroku $7 (Web App server) and $9 for Postgres database?

It's 17:55... Did much work that day since I came in earlier than usual, so I could leave in time and do some shopping with the girlfriend.

A colleague comes in to my room, a tad distressed. He had accidentally ran a fixture script on a production environment database (processing a shipload of records per minute), truncating all tables...

Using AWS RDS to rollback the transaction log takes up about 20m. I had to do that about 5 times to estimate the date and time of when the fixture script ran... Since there was no clear point in time...

Finally I get to the best state of the data I could get. I log in remotely run some queries. All is well again... With minor losses in data.

I try to download a dump using pg_dump and apparently my version is mismatched with the server. I add the latest version to aptitudes source list of postgres repo and I am ready to remove and purge the current postgres client and extensions...

sudo apt-get remove post*
Are you sure? (Y/n) *presses enter and enters into a world of pain*

Apparently a lot of system critical applications start with post... T_T

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.

My preferred stack is Rails/NginX/Postgres, or Node using the same.

I have a fair amount of material for this week's rant, but in my stack's defense, the quantity is primarily because I've been using it for so long, and I'm apparently a talented breaker. I may share other stories if the motivation arises.

However, today I ran into something definitely deserving of calling out.

The default datatype for a Date+Time column in Postgres is `datetime` which means "date+time without timezone". (while `datetimetz` instead stores the timezone).

Apparently when comparing a datetime with a datetimetz, Postgres doesn't compute the timezone difference correctly, leading to some very unexpected and confusing query results.

Today, I had a record that was both pending (expires_at > now) and expired (expires_at <= now), where now is a DateTime (with tz) literal from Rails. After half an hour's frustrated delving and baffled expressions at query results, I finally figured out that the database's math was incorrect when comparing UTC (+0) and PST (-7).

This during a semi-high-priority bugfix that's blocking for a coworker.

While Time and all of its nuances are honestly extremely difficult to handle correctly, I didn't expect Postgres to get this relatively simple part wrong.

Shame on you, Postgres.
I expected better.

I saw a self called "senior developer" store a boolean as a "t" or "f" in a character varying with a max of one character in our postgres database. wtf

I had a nightmare where the PHP elephant was charging to attack me... nothing like the friendly Postgres elephant.

A little late but whatever.

About half a year ago, I started working on setting up self hosted (slippy) maps. For one, because of privacy reasons, for two, because it'd be in my own control and I could, with enough knowledge, be entirely in control of how this would work.

While the process has been going on for hours every day for about half a year (with regular exceptions), I'll briefly lay out what I've accomplished.

I started with the OpenMapTiles project and tried to implement it myself. This went well but there were two major pitfalls:
1. It worked postgres database based. This is fine but when you want to have the entire world.... the queries took insanely long (minutes, at lower zoom levels) and quite intimate postgres/tooling knowledge was required, which I don't have.
2. Due to the long queries and such, the performance was so bad that the maps could take minutes to render and when you'd want that in production... yeah, no.

After quite some time I finally let that idea sail and started looking into the MBTiles solution; generating sqlite databases of geojson features. Very fast data serving but the rendering can take quite some time.

After some more months, I finally got the hang of it to the point that I automated 50-70 percent of the entire process. The one problem? It takes a shitload of resources and time to generate a worldwide mbtiles database.
After infinite numbers of trial and error, I figured out that one can devide a 'render' (mbtiles aka sqlite database) into multiple layers (one for building data, one for water, one for roads and so on), so I started doing renders that way.
Result? Styling became way more easy and logical and one could pick specific data to display; only want to display the roads? Its way more simple this way. (Not impossible otherwise but figuring out how that works... Good luck).

Started rendering all the countries, continents and such this way and while this seemed like a great idea; the entire world is at 3-4 percent after about a month. And while 40-70 percent generates 10 times as fast, that's still way too slow.

Then, I figured out that you can fetch data per individual layer/source. Thus, I could render every layer separately which is way faster.

Tried that with a few very tiny datasets and bam, it works. (And still very fast).

So, now, I'm generating all layers per continent. I want to do it world based but figured out that that's just not manageable with my resources/budget.

Next to that, I'm working on an API which will have exactly the features I want/need!

Is there automation tool for postgres or mysql to fire a query? I got a db that will reset the row column value after 1 month of the created date

Edit: I know this is not SO

Not clearing the rows, just resetting the value of some rows if the criteria is met

Hmmm :^)

Lets make 10% of the business logic as postgres functions. ☠️

Spent about six hours writing tests and coding a user log in system for a Rails app last night. Finally finished at around 2:00am. Commited, pushed and merged, then called it a night.

Woke up today and Postgres is refusing to play nice. Spent twenty mins or so fixing that and then ran rspec.... Two thirds of my tests are missing - everything I wrote last night. I check my code and sure enough, they aren't there.

Wild panic ensues for a solid 5 mins before I realise I didn't actually pull the updated master branch after deleting my feature branch last night.

Now I feel like an idiot, but a relieved one.

When they want to take a business critical app that is using Enterprise Oracle running on Exadata, and move it to community Postgres running on Amazon RDS, because "it will be in the Cloud, and it will save us money..." No, no it won't.

Starting out as a developer: I don't know why people are so stingy about tags on Stack overflow

Now: This guy tagged this question with SQL Server but is asking about Postgres I don't know how to help this guy out

!rant

Working with postgres is just a great experience every time, I've never EVER had a problem with it.

and it's so insanely POWERFUL!!!!

great role model of what all open-source software should strive to be

Bloody mother fucking jesus christ....

It's working.

Sometimes I really wish I had the gift to be creative and to e.g. draw a (metaphoric) image of the shit I had to fix and how it felt to fix it.

It's sad not being able to share stuff in a way everyone can understand it :/

I uncludged the last bits of the networking / loadbalancer / craptastic network.

The whole chart that includes most of the associations / information for the network fits easily on a A2 paper. Internal only.

Just migration of a few remaining servers to Proxmox and a large MySQL to Postgres migration outstanding....

1.75 years and it's the first large milestone achieved. Large milestone as in it will not be a total clusterfuck anymore.

Still a lot of stuff to do...

But down to one major OS, Debian, for everything (container / VMs)... only LTS supported versions for services...

No more stuff that's so old it's near fossil state. We stillhad Ubuntu 12.04 running... :) ;) And XenServer is nearly gone...

Too many feels. Too many brain poofs. And way too much pain.

I'm the only dev in a project. I'm a frontender. It was supposed to be a front end project. Now I know more about ruby and postgres than I wanted. Thanks for learning opportunities, I guess. Good that the deadline is still pretty far away.

My kingdom for Postgres queries that run under 40 minutes...

Set up my little raspberry pi and installed postgres. Now when it boots I can ping it for about half a minute then it crashes. So I'll install it locally I guess...

I would like to murder postgres and the awful requirements of this damn project... Plus, I practically didn't sleep more than a blink last night so either postgres fucks off and gets its shit together with its transaction handling shit, or imma about to stab a bitch! 🗡 ⚔️

FredBoat, largest open source discord bot.
Making all the things work + making it scale when demand kept climbing was a challenge where we had to learn simple stuff like postgres, working with 3rd party apis, generally good coding patterns and maintainable code, but also rather advanced stuff like making the garbage collector play nice, profiling memory leaks and optimizing the hot path, as well as high level topics like cutting the codebase into scalable domains and services.

I wrote some simple pen test scripts that automatically get executed on every ip in my fail2ban log.

Ip count: 2500+ in a few days. Probably victims of botnet. Some have mysql, postgres, smb open and many of them support user/pass auth on their ssh.

The scripts were a lot of fun to write but I don't expect much results.

Me after Linux reinstall: "this is great, now let's get back to work. Let's install the packages, then let's run the test server. What do you mean postgres can't be found? Wait... Fuck. Fuck. Fuck." When you realise that you forgot to backup the test database 😂

So why on earth would Postgres not spell this correctly?
```select rolname from pg_roles;```
Is it that someone could not spell rolename correctly?

Official Postgres docs:

"If you simply write:

DELETE FROM products;
then all rows in the table will be deleted! Caveat programmer."

"Caveat programmer"... "Cavea...." "Cave..."

Someone out there is reading this with bloodshot eyes, 3 am, stuck reading this on repeat and prefers that The Ring movie is true and would rather take that...

wtf...

Ones of the best bugs I love the "most" are the ones where the fix is counter-intuitive, e.g. making smth seemingly incorrect to rectify the issue.

Like today, I crafter an SQL query to fetch some PG metrics. And postgres-exporter refused to accept it until I added an excessive comma [,] at the end of the SELECT block (right before FROM).

Like.. wtf...

How to screw with other developers?

Expose postgres at Port 5435.

I spent 15 mins trying to figure out why my dev machine doesn't connect to the RDS instance.

What's your worst debugging experience?

I just had it today and yesterday when I tried to connect to an aws postgres rds..... 😭😭😭

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.

So I'll just stick to pgAdmin 3.

Today I learned what actually happens if you don't close your database connections (because you forget) after you've used it. Feck all happens for the first 9 requests, and after that error 504 😂

Oh dear! Knew this email from Heroku was going to come saying I'm approaching by limit for the free Postgres database...Guess I'll have to start trying to monetize this website to pay for the next tier 😅

Excel plus CSV into word with mail merge into outlook to send.

Lovely integration.

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?

i'm starting a project where i will have a large amount audio clips, anywhere from a few seconds to about an hour long, and i need to store them based on which user created them and what group they are created in (so they will be sorted based on two integers). i'll need to concatenate and/or merge the audio files frequently, and i may need to filter which audio i use based on users and time created.

how should i store the audio? i'm pretty sure a database is the best option, but should i consider using the file system? if i shant, should i use mysql or postgres? i know postgres has more types and supports complex queries.

does anyone have experience who can help?

Rant on stackexchange detected.

Created a hidden role in the Postgres database, with some tricky constraints, which only a DBA can find and remove, to give myself, disguised as the postgres account, a role which no one else in the system can have.

Called it "pharaoh". Thug life ;

Thank you, company forced windows update! My 60 minutes reconfiguring rabbitmq and postgres were well invested instead of investigating the memory leak fucking hibernate causes.
I'm done.

Everyone I tell this to, thinks it’s cutting edge, but I see it as a stitched together mess. Regardless:

A micro-service based application that stages machine learning tasks, and is meant to be deployed on 4+ machines. Running with two message queues at its heart and several workers, each worker configured to run optimally for either heavy cpu or gpu tasks.

The technology stack includes rabbitmq, Redis, Postgres, tensorflow, torch and the services are written in nodejs, lua and python. All packaged as a Kubernetes application.

Worked on this for 9 months now. I was the only constant on the project, and the architecture design has been basically re-engineered by myself. Since the last guy underestimated the ask.

Knowing SQL does not mean knowing all the existing technologies that uses SQL, motherfucker! Stop bragging around that you know Postgres, SQL Server, Oracle and shit.

IT is full of shit talkers and ego, NNNNNNNNNGGGGGGGGGGHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

So, here we are using postgres in production with the fancy feature of UPSERT. We’ve got loads of request popping in, both new and updates - so the UPSERT getting triggered alot. Today we faced a problem with integer within our app stating that the number is too high. We were like «WTF? Already?!»! After looking in to the features of UPSERT, we came to realize that any sequence will be incremented regardless of an insert being handled. This results then in an ID field being defined with ids such as:
1
2
5
19
222
73377
282828282
Etc. You get the point..
This design is so WTF and I have absolutely no idea why anyone would like their IDs to be generated and incremended even though there is no insert. I hope it is due to my naivity that I cannot comprhend it. Oh well. UPSERT, you’re forever gone 👍🔥

You use Postgres.
I use DNS TXT records.
We are not the same.

Client be like:
Pls, could you give the new Postgres user the same perms as this one other user?

Me:
Uh... Sure.

Then I find out that, for whatever reason, all of their user accounts have disabled inheritance... So, wtf.

Postgres doesn't really allow you to *copy* perms of a role A to role B. You can only grant role A to role B, but for the perms of A to carry over, B has to have inheritance allowed... Which... It doesn't.

So... After a bit of manual GRANT bla ON DATABASE foo TO user, I ping back that it is done and breath a sigh of relief.

Oooooonly... They ping back like -- Could you also copy the perms of A on all the existing objects in the schema to B???

Ugh. More work. Lets see... List all permissions in a schema and... Holy shit! That's thousands of tables and sequences, how tf am I ever gonna copy over all that???

Maybe I could... Disable the pager of psql, and pipe the list into a file, parse it by the magic of regex... And somehow generate a fuckload of GRANT statements? Uuuugh, but that'd kill so much time. Not to mention I'd need to find out what the individual permission letters in the output mean... And... Ugh, ye, no, too much work. Lets see if SO knows a solution!

And, surprise surprise, it did! The easiest, simplest to understand way, was to make a schema-only dump of the database, grep it for user A, substitute their name with B, and then input it back.

What I didn't expect is for the resulting filtered and altered grant list to be over 6800 LINES LONG. WHAT THE FUCK.

...And, shortly after I apply the insane number of grants... I get another ping. Turns out the customer's already figured out a way to grant all the necessary perms themselves, and I... No longer have to do anything :|

Joy. Utter, indescribable joy.

Is there any actual security reason for disabling inheritance in Postgres? (14.x) I'd think that if an account got compromised, it doesn't matter if it has the perms inherited or not, cuz you can just SET ROLE yourself to the granted role with the actual perms and go ham...

so my friend and I are canvassing NLEs for our guys at the Post Production squad in our project (we were in charge in infrastructure). We looked at Premiere since it's kinda ok until we found Black Magic Design's Da Vinci Resolve.

First of all, I was suprised with the price. 299 for the Studio Version? Holy fuck, that's cheap as hell! Then there's a free as in free software version which has the core editing features with 1080p rendering. So we grabbed that and kinda suprised it requires postgres but as seeing Resolve having collab and render queues, it makes sense.

Installed them on the PCs the postprods gonna use, they were amazed. We literally saved 500 bucks for an NLE. When they asked how much is it. Our reply was:

"That's free".

and there was silence...

"And it's also 299 bucks for the cooler version".

And silence still ensued.

Guess our guys wasted alot of money on a pipeline that is cheap as hell but more jam-packed than any other NLE found in the market.

Props to you BlackMagic Design.

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.

created a new stack.

This is a part rant-part question.
So a little backstory first:
I work in a small company (5 including me) which is mostly into consultation (we have many tech partners where we either resell their products or if there is a requirement from one of our clients, we get our partners to develop it for them and fulfill the client requirements) so as you can see there is a lot of external dependencies. I act as a one-hat-fits-all tech guy, handling the company websites, social media channels, technical documentation, tech support, quicks POCs (so anything to do with anything technical, I handle them). I am a bit fed up now, since the CEO expects me to do some absurd shit (and sometimes micro manages me, like WTF I am the only one who works there with 100% commitment) and expects me to deliver them by yesterday.

So anyway long story short, our CEO finally had the brains to understand that we should start having our own product (which i had been subtly suggesting him to do for a while now!).

Now he came up with a fairly workable concept that would have good market reach (i atleast give him credits for that) and he wanted me to suggest the best way to move forward (from a both business and technical point of view). The concept is to have an auction-based platform for users to buy everyday products.

I suggested we build a web app as opposed to a mobile one (which is obvious, since i didnt want to develop a seperate website and a mobile app, and anyway just because we can doesnt mean we have to make a mobile app for everything), and recommended the Node/react based JS tech stack to build it.

At first he wanted me to single handedly build the whole platform within a month, I almost flipped (but me being me) then somehow calmed down and finally was able to explain him how complicated it was to single-handedly build a platform of such complexity (especially given my limited experience; did I mention that this is my first job and I am still in college, yeah!!) and convinced him to get an experienced back-end dev and another dev to help me with it.

Now comes the problem, I was to prepare a scope document outlining all the business and technical requirements of the project along with a tentative cost, which was fairly straightforward. I am currently stuck at deciding the server requirements and the system architecture for the proposed solution (I am thinking of either going with AWS - which looks a bit complicated to setup - or go with either Digital Ocean or Heroku):

I have assumed that at peak times we would have around 500-1000 users concurrently

And a daily userbase of 1000 users (atleast for the first few months of the platform running)

What would be the best way forward guys?

I did some extensive (i mean i read through some medium blogs! and aws documentation) research and put together the following specs (if we are going through AWS):

One AWS t3.medium ec2 instance for the node server (two if we want High Availability by coupling with the AWS load balancer and Elastic Beanstalk)

The db.t3.small postgres database

The S3 Storage bucket (100gb) for the React Front end hosting

AWS SNS for email/sms OTP and notification

And AWS CloudMonitor for logging amd monitoring.

Am I speculating the requirements properly, where have I missed??

Can u guys suggest what is the best specification for such a requirement (how do you guys decide what plan to go with)?

Any suggestions, corrections, advices are welcome

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!

Probably the weirdest single command I have ever entered so far:
apt-get install postgresql-12 postgresql-11 postgresql-10 postgresql-9.6

In other words - testing an internal tool across all of our supported postgres versions, but... Just found it funny in a way... Dunno, maybe my humor is just weird.

Way back no full stack. Now theres full stack and companies expect us also to be full stack + DevOps God that knows Azure, AWS, Jenkins, Docker, Ansible , puppet etc.

They want to save money and hire a one man IT department.

Full stack web and mobile developer with DevOps God skills.
Frontend = Angular React
Backend = Java Python
DB = NoSQL, MySQL, Firebase, Postgres

tried to stress-test an authenticated websocket endpoint (that makes 2-3 DB calls) by opening closing randomly and it crashed after 20-30 times within a few seconds

I was focused on the middleware glitching out, but error was in the DB-Postgres coz of multiple-connections

Even if I increase the upper limit of simultaneous open connections, the problem at-scale will still exist
If I tried to use a static forever-open connection, it errors out coz 1-command-at-a-time per connection

so im constrained on both sides -.-
Either I rate-limit the endpoint in general and force-close open connections or I cache Organisation-level info that rarely changes

this is one of the few times I miss MS-SQL, it can take a beating but still serve without much complains or losing data consistency -_-

Created a CRM for the business which integrated every database in the network, SQL Server, Postgres, Firebird and MySql types. Evolved to writing a series of procedures which replaced a staff members full job though..

Do people still use redis when you already use postgres? How is pg perf if you are writing like 10,000s of row data/second. I am slightly outdated....

Migrate ProdDB to postgres tonigth. Couse you dont have a life waiting at home. :'(

Anyone got experience turning a Raspberry Pi 3+ into a mini Ubuntu server running Postgres and some other shit. Seems like a heap of steps and was it worth it? Looking for a little testing server travel buddy.

Frontend people, I need your opinion.

I will soon start building the next version of a rather large project's frontend but I am mostly a backend guy.

It is a custom made web application (PHP, Postgres) that handles all business aspects of a shipping company of about 50 people (trucks, truck free space in shipments for new packages, package tracking via gps on the truck, invoicing, reselling shipping services to other businesses, everything).

The existing frontend is using an ancient version (1.x) of the YUI framework and uses AJAX heavily to refresh the user interface. It's usable, but maintaining and extending it is getting really hard as the project grows larger and larger and more systems are integrated.

So the question is, given this use case, what JS framework do I use and what is a good resource to start learning it?

Formed teams with a few people from university I wasn't really compatible with. I wasn't prepared well either and it was my first hackathon. We bounced about a few ideas and decided to build a simple Javascript game, a Python backend and Postgres dB, techs I was barely familiar with at the time. Wasn't involved/couldn't contribute in the design or help much with coding. It was a humiliating experience overall.
Changed teams and formed a team with like minded people 4 months later and was better prepared this time. Built an app for social innovation and came runners up at the hackathon!

Hey remote workers.

What would be your advice for someone with experience that's interested in exploring remote work.

I'd like to target this question to remote workers that live outside USA/EU/UK. Say South America, South Asia.

A little introduction.

I'm a full stack engineer, did one project in embedded systems with QT/C++/RPI can do backend in Python, Node, Java, C#. I have some experience with React Native (just 2 apps)

I currently I do full stack with Node, React, postgres and caching with couchdb.
I gather requirements, write the projects, proposals and then I do the implementation. (Really full stack, I kinda like it though, when I'm bored with code I pick up an issue and contact the client to socialize/get answers. I found out that nondevs like to feel they talk to a human not a robot)

I'm making about 600usd/month (dev in a poor country) working 30hrs /week. I'd like to ramp up my income, working remote part time to fill up about 50hr week.

What can I expect?
Where do I start?
Are there part time opportunities for working remote?
What kind of roles are in demand?

I am the responsible for the atlassian Suite at work, as I maintain the systems, set them up, and stuff.

One day, our crowd (the authentication and authorization application) just went crazy. At like lunch time it could not connect to the AD anymore. No reasons. Throwing XSRF errors (cross site scripting), because http would connect to https. "won't do it, fuck you" it told me. Out of the blue. Noone changed anything. And yea, seriously. Noone did.
It just refused to connect (as connecting to AD is connecting yourself with you own api. And refusing yourself talking to yourself). It runs behind a proxy. Therefore http/https. Well, this worked for years. But out of sudden not anymore.

Yea. Fuck you.

It was reported some hours later, at like 3pm, as people could not login to the applications using crowd as authentication and authorization server.

Tried to debug the system, where nothing was did, to make it work. At best time to fail.

First workaround: if you are logged into one of the other applications of atlassian, just refresh the site, so your SSO token gets a refresh and you are signed on again.

Then I searched more and more. And more.
But nothing worked, nothing helped.

So I addressed an emergency maintenance, take down the whole Suite, restart crowd, to apply some changes to it's settings, not knowing what happening then, because all connections of SSO will then be released. Sent out the mail like 30 minutes beforehands.

While waiting for the window, I just typed my credentials... And redid, and redid, so to type and being bored.
Three minutes before the window...

It just worked again.

Well. Wtf. Serioudl
Just came back.

No Intrusion, no changes at all. Just came back, as nothing has happened.

Kind of best part of this story... A headhunter messaged me on my way home to offer me a job as an Atlassian Suite SysAdmin for a company, at kinda the double of my salary.

At first I was thinking to go there, and when someone then asked me sth about Atlassian just start to laugh and then leave still laughing...

But then I very nicely respond that I dont want to cry at work. And wished him best luck.

I am doing some bad upgrades now on our Suite. Very painful.
And I looked into the start scripts. Some Look like the untalented intern tells another one to write scripts. Seriously wtf.

Today I followed the guide to Update a confluence and change database to Postgres. Didnt work, Postgres error.
Try it again, jquery won't load. Next try, tomcat not starting anymore. Did same thing. Every fucking time.

Yea. Maintenance window to get a nice new export soon. Will only take an hour.

To switch database in confluence, you need to set it up very fresh. And then Import your export.
Export takes an hour at our system.
Importing maybe the same time. Hope it will work (hint: Nope).

Oh, can be nice also. Just tell the Bitbucket to migrate databases, there is a fucking setting for it. Enter new database, ready, go, finished.

At least they don't raise costs very much every kinda year.
Oh sorry, yes, they do.

One month ago I had to start a school project with some my classmates. I managed all the infrastructure using terraform and today, the day before the delivery, I noticed that the graphs used for the monitoring always been so quiet. I decided to ask my team what was going on and these are their replies:
- "I thought IaC was more describing the actual infrastructure"
- "I didn't know we have a database on AWS, I always used my local postgres instance"
- "Why do we need to host our web app on AWS? I can just run it from Visual Studio"

I don't think I want to live on this planet anymore

Man, I love Postgres, but one thing I hate about it is its naming scheme.

As far as I know, there is... None.

So I'm always left wondering how certain configuration directives referring to Postgres will be written down as.

Pick your favorite:
Postgres
PostgreSQL
Psql
PgSQL

And maybe more...

Or is there a naming scheme / system I'm not aware of?

honest question: if I know ReactJS, Golang, Python, Typescript, and a bit of Postgres and living in Costa Rica, what sort of freelance services could I promote on the net?

I used to freelance on sites like PeoplePerHour, doing projects of 1 month in 3 weeks or less, but I would like to do that again in my own website under my own terms, sort of speak.

any recommendations?

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'`

Pew pew...

SCADA looks like something really interesting to learn.

Anyone familiar with it, what packages to get started with?

I was thinking of building a simulator api, maybe to flex and train what I'm learning in postgres, but I don't know where to begin yet. Seems like a big topic.

Hey guys, could anyone tell me what's needed to become a proper Angular developer(like full-stack)? I know MongoDB, Postgres and all of the frontend stuff(HTML5, CSS, etc), plus Spring and Hibernate. Also, I use Linux, so count in Bash.

Surely there'd be other bundles of Angular besides MEAN?

I'm used to using PostGres, have been forced to use MySQL for this project. After a day of pain I would like to firmly declare: I hate MySQL.

Just spent 4 hours on a bug with Postgres in Node. Turns out when you create a new client, and then end it, You need to create a NEW client (I guess because the old one is bad??).

Thanks for the shitty error messages Postgres. I want 4 hours of my life back.

I swear to god: you can use lolcode on postgres...

If you are into Postgres and don't know this guy than I don't know what to say...

I wonder if he's on devRant

What stack do you like? PERN stack 😏
Postgres Express React Node

I watch lots of PERN tutorials! 😉

LINUX MASTERS, I can't believe that linux didn't get rid off yet of the annoying user:group system.

Anyway, I have two pre-existing groups(postgres & www-data), now I need to enable both groups full access to an HD for data storing, currently the owner of /media/"user"/DATA is www-data but I need to enable the postgres group to operate in it.

I seached around and can't get around how to accomplish this, if it's even possible.

Help >_<

I am going to write my thesis on Electron and plan to create another Postgres client as everything i found does not serve my need.

So my questions are: What features do u like in a Postgres client

Also Ultimate question 🙋 What would it be named 🤣😂

When did we decide managing Users through Cloud REST architecture was more secure than having them in an underlying DB?

Because I can't put my finger on exactly why... but I don't like it and I think it's probably less secure... and just spawned from the need to be able to make user management a subscription based service like fucking everything? When a simple MySQL or postgres and some bcrypt somewhere would be both more secure and infinitely cheaper?

I'm more used to consuming REST API's than writing them. Can any you REST peeps help me understand how a REST API could be made as secure as a SQL DB connection for user management?

What do you think the attack vectors are for a REST API User Management? Like... what's the SQL injection of REST API? Pack some extra JSON somewhere or something?

At least if I can have faith my shit's not gonna get hacked because I have to use a 3rd party REST service for User Management of Users to my own fucking app I can maybe sleep tonight.

MAC MINI UPDATE: ayy nextcloud (also postgres is a hassle)

A question to all software security specialists of devRant. Please, take it serious.

Is it fundamentally possible to restrict a SQL database like Postgres in a way that unintended SQL queries are impossible to execute? Perhaps in some kind of whitelist fashion. Is it possible to achieve the kind of security that will be just fine exposed to the outside world akin to "SQL queries in onClick handlers" scenario?

Or is this an uphill battle of never being able to moderate an infinite set of possible fraudulent queries?

Level of fuckity fuck mood.

After changing dozens of build plans in Bamboo, the build system of poo...

How to verify that nothing has gone wrong?

Poking the database, you'll be surprised that Bamboo stores the buildplan definition as XML.

Another surprise: Some of the keys / values have typos.

Yeah. You read that right. There are typos inside the XML...

Now together with Postgres, we can use XPATH and have some fun.

UNNEST(COALESCE(XPATH('/configuration/buildTasks/taskDefinition[userDescription[contains(text(),"Bleep")]]', build_definition.xml_definition_data::xml)::varchar[], ARRAY['']))

Lovely wrapping via coalesce for some null safety.

Now we get da task definitions for fields having user description text containing bleep.

Wrapping it in two REGEXP_REPLACE to strip out stupid identifiers....

REGEXP_REPLACE(REGEXP_REPLACE(...., '<id>\d+</id>', ''), '<oid>\d+</oid>', ''))

Then wrap that in MD5.

Boom. Lots of MD5 sums to help you identify if the configs are identical for a task or not.

Now wrapping that in another select to group by the MD5 and filter out the non identical ones.

I hate it how sometimes one has to seemingly do a full 2 hour dance for something as stupid as validation.

I'm pretty glad though for XML and XPATH.

Cause otherwise that would have been a whole can of worms I don't wanna think about....

In Postgres, parallel query works by having multiple workers....

As such, depending on workers available, queries can run theoretically fast (workers available) or slow (workers not available) - right?

Question is: are there more optimizations like this... And is my assumption correct?

It seems like a major pain in the ass... Scalability and reliability wise. (?!)

We have a notorious question in one of our coding interviews, designed to weed out people who've slapped 'Postgres' on their CV (because that's what we're looking for) when what they really mean is "I've used MySQL a lot, and it's basically the same, right?". People get choked on that about 70% of the time.

If you put something technical on your CV, be prepared to be tested on it in a coding interview!

Had to optimize today a DB File / MySQL 5.7

I'm sometimes sad that software cannot bite people in their crotches, shit in their faces and fuck their eyes out.

The config was non commented and a disaster.

Yay. Let's set thread_cache to 16K while max connections is 50.

And raise limits like max files without adjusting SystemD / ulimit

And OF COURSE MySQL sucks...

So let's migrate to PostGres.

*Brainfart*

This has happened way too often.

Really. Software should have the right to punish dumb people. At least ... 10 kv shock to teach a lesson.

That moment when you realized that you need to go with m4.4xlarge or c4.4xlarge

Why YouTube tutorials mostly shows postgres and not MySQL/mariaDB?

I have this love-hate relationship with strong typing.

Right now, the types are shared between:
Postgres <-> DB Data Models <-> GraphQL <-> TypeScript <-> MobX-State-Tree

What’s the appeal of Microsoft SQL Server 2019 over something free like PostgreSQL or MariaDB?

TL;DR I have to bump a Redis cluster from t3.medium to m6g.large just to get enough network bandwidth even though I have no need of the extra memory.

Debugged an interesting issue today.
I am adding Elasticache to a project to reduce strain on the single node postgres DB.
Deployed a Redis replication group with 2 shards, with multi-AZ replication for resilience.

Everything was going well. We arent caching that much atm so was barely using 100Mb of memory.

Suddenly, when our US region comes online, latency skyrockets and the logs are full of Jedis timeout errors.
Still no issue with memory or node CPU.

The cause? Arbitrary network bandwidth throttling by AWS. The app currently processes about 3,000 requests per second so we were exceeding Amazons random ass allowances which arent documented anywhere.

I wanted to resetup my gitea on a newnserver and now? I can't connect with the postgres db and i have literally no idea why. it fucking worked when it ran on my old debian and now it won't even connect.

😭

RDS Proxy is quickly becoming my least favourite AWS offering.

I ranted about it a while back because I had to abandon it for a project because it doesn’t support clusters very well (it only proxys to the primary node).

Well I tried to use it again for a different project with only a single RW instance. Surely it will be ideal?

Nope. It doesn’t support Postgres 13. Only goes up to 12.

What the hell Amazon?

pgbouncer it is I guess.

Oracle 11g DB or whatever version it was!! You need a fucking windows machine to install it, doesnt install on Linux or Mac!! I am a MySQL/Postgres guy, working on it was a nightmare, permission issues, and you need the oracle instant client on your system to communicate with windows, which works after a zillion errors!!

I am new to redis and confused how this works

To keep it simple lets say i have a CRUD service for user

- POST user, just creates user

- GET user by id, fetches user but using annotation @CacheEvict(). This method has a Thread.sleep(3000) before fetching user

- GET all users, fetches all users but using annotation @Cacheable()

- PUT user by id, updates a single with annotation @CacheEvict(). This method has a Thread.sleep(3000) before fetching user

- DELETE user by id, deletes a single user with annotation @CacheEvict()

---

GOOD:

When i GET user by id, i wait 3 seconds and then get the fetched user

When i GET user by id again, i get the fetched user instantly in 5 ms. This means it has pulled the user from REDIS cache instead of postgres

---

PROBLEM:

If i PUT user by id, update some data, and then if i GET user by id, it will return the user in 5 ms BUT the outdated user! Not the newly updated one. Because the Redis cache configuration has not expired yet. So there are now data inconsistencies

---

QUESTION:

How can i know When was something updated, deleted or whatever, so that i can fetch data from postgres (latest data) instead of Redis cache (outdated data)?

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.

Microsoft server licensing - so complex that it's probably easier to add Postgres support to my app and run the database server on Linux instead, than to try to make sense of MS license rules.

ORM feels like, I can do better than that, with more predictability (like naming, table creation, and stuff).

The only pro, is hopes for inter-dialects interop (SQLite-Postgres-MySQL-MariaDB).

OK, I also want SQLite-MongoDB interop, because of the cheap price; but this is difficult.

I want to start with web development and combine ESP projects with a nice interface or just to make a small websites showing algorithms in an animation. (Just as examples) But where the hell do I start. I have a background with C/C++ and python but want to develop more skills. Like do I go with react, node.js, typescript and postgres or something else? And what are the first steps I should take? If any of you got tutorials they can recommend I'd really appreciate that, because I feel like there are a ton of BS tutorials out there...

Can someone send me a guide article or tutorial how to build a chat app with kafka/redis in spring boot?

Should kafka or redis be used?

Or something else?

Also in a chat app should i store messages in postgres or not?

FUCK YOU AWS Elasticsearch!!
Fucking lossing data on cluster upgrade. Fuck you! Now I have to rebuild the goddann records from Postgres database entries.
Cunt AWS ES. Screw you!

Has anyone used plpgsql? You almost have to sacrifice a goat during the function declaration in order for it to work.

We got this feature on our app where if you change the status of an action item, it moves down/up to join its brethren of the same status at the bottom of its respective grouping. This is also true for creation.

Problem is: Testing.

I embarked upon this fuckin ridonkulousness today where I had to test all possible scenarios. Empty list, list with only A status, list with only B, list with A and B, list with A and C, etc etc

9 fucking hours later and a lot of anger, I am finally done. I powered back probably 10 club sodas, 6 teas, and had chillstep rollin all day.

If y'all ever feel like giving up because shit's hard, keep pushin. You'll get it eventually ;)

Why has nobody at Microsoft thought of implementing optional parameters for functions in SQL Server? I guess backward compatibility is something they haven't heard of. I mean hell, Postgres can do it easily.

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 JetBrains

I thought I had to VARCHAR in non-SQLite RDBMS. I was wrong. There is TEXT.

1. PostGres seems to work better with TEXT.
2. There is an ORM that forces VARCHAR (255) by default.
3. But you can go over the limit without throwing errors.

anyone find mysql infinitely more time consuming than postgres? i cant do CTE anymore 🤔
