Giant Warning Dialog: YOU ARE CURRENTLY ENTERING THE STAGING ENVIRONMENT

Users: Ok

App: *Completely different colour, I’m talking bright unsightly yellow*

User: Ok

Giant Yellow and Red Flashing Banner at the Top of the Screen: WARNING YOU ARE CURRENTLY USING STAGING, THIS AREA IS FOR TESTING ONLY

User: The production environment sure is acting strange today. It’s a weird colour and I don’t recognize any of the data, it’s all just dummy filler data. I better create a ticket for the dev team to check o—….. no wait I’ll send an email CC everyone including the CEO and sound the alarm production is currently down and filled with giant warning messages.

Manager: OH MY GOD PRODUCTION IS DOWN DID YOU HEAR ABOUT THIS??? WHAT THE FUCK COULD THESE WARNING MESSAGES BE THAT’S ONLY SUPPOSED TO HAPPEN ON STAGING! THE CEO IS BREATHING DOWN MY NECK YOU NEED TO GET THIS FIXED IMMEDIATELY!!!!!!!

Dev: …

Google sucks!
No, not as e-mail or for privacy reasons. Sure, that too, but it comes with "free" stuff.

It sucks because it's breaking every possible record in the worst, shittiest, most insanely stupid APIs and integrations out there on the entire fucking planet!

It is comically stupid!

Aside from their LOVE of hard-deprecating APIs every few months, requiring constant, time consuming maintenance of every tool that integrates deeply with Google services, some of their APIs, for expensive stuff, look like they've been written by Bobby McFartface from 7th grade.

Take a look at DoubleClick Search (their ad performance reporting tool, that sure does sound like one). To upload custom, additional data, you must pass in a ton of parameter, and they REQUIRE some of them to have a specific, hardcoded value. What's the point in passing that parameter then you dickheads?!
But fine, so you uploaded some stuff using the API. Now you want to delete everything and try again after you fixed a bug - well you fucking CAN'T! You can't delete stuff, you can only mark them as "deleted" using an update call.
Bulk operations? Fuck no!
Can I just add on top? Well of course not! That will raise a ton of exceptions. Same message should be transmitted using the PUT, not POST request, in order to edit.
Can I send everything to PUT? Of course not! You can't edit something that's not there, dummy!

Can I see what's there so that I can update it, and add what's missing?
Well of course not! Why on Earth would you need to see what information is in there after you uploaded it? Who needs that anyway?

Simply send, pray, and hope that everything will be fine (it will not).

Like holy fucking crap, it can't get any more stupid!
Google is a huge pile of idiots who feed on only a single cow - the search engine.

It's times like these when I think that Google right now is the worst thing that exists for everyone in tech. It's dragging everyone down with their monopolies everywhere and complete idiocy in managing them.

Don't ever ever forget to push before leaving office.
I repeat : Don't ever ever forget to push!
Sends app to client.
At home and decides to check if the changes actually worked just to realize it crashes because i forgot to comment out my dummy test data.

*On a bus back to the office at midnight*

We developed an application and deployed on production (but not launched)
And business team already created lot of garbage or dummy data. Reporting systems are huge pile of bars, stats and shit.

Now, has to destroy and clean production.

Already advise them to do experiments or testing dev or staging.

Damn. First time in my career experienced this. Has to delete production.

When I was in 11th class, my school got a new setup for the school PCs. Instead of just resetting them every time they are shut down (to a state in which it contained a virus, great) and having shared files on a network drive (where everyone could delete anything), they used iServ. Apparently many schools started using that around that time, I heard many bad things about it, not only from my school.
Since school is sh*t and I had nothing better to do in computer class (they never taught us anything new anyway), I experimented with it. My main target was the storage limit. Logins on the school PCs were made with domain accounts, which also logged you in with the iServ account, then the user folder was synchronised with the iServ server. The storage limit there was given as 200MB or something of that order. To have some dummy files, I downloaded every program from portableapps.com, that was an easy way to get a lot of data without much manual effort. Then I copied that folder, which was located on the desktop, and pasted it onto the desktop. Then I took all of that and duplicated it again. And again and again and again... I watched the amount increate, 170MB, 180, 190, 200, I got a mail saying that my storage is full, 210, 220, 230, ... It just kept filling up with absolutely zero consequences.
At some point I started using the web interface to copy the files, which had even more interesting side effects: Apparently, while the server was copying huge amounts of files to itself, nobody in the entire iServ system could log in, neither on the web interface, nor on the PCs. But I didn't notice that at first, I thought just my account was busy and of course I didn't expect it to be this badly programmed that a single copy operation could lock the entire system. I was told later, but at that point the headmaster had already called in someone from the actual police, because they thought I had hacked into whatever. He basically said "don't do again pls" and left again. In the meantime, a teacher had told me to delete the files until a certain date, but he locked my account way earlier so that I couldn't even do it.
Btw, I now own a Minecraft account of which I can never change the security questions or reset the password, because the mail address doesn't exist anymore and I have no more contact to the person who gave it to me. I got that account as a price because I made the best program in a project week about Java, which greatly showed how much the computer classes helped the students learn programming: Of the ~20 students, only one other person actually had a program at the end of the challenge and it was something like hello world. I had translated a TI Basic program for approximating fractions from decimal numbers to Java.
The big irony about sending the police to me as the 1337_h4x0r: A classmate actually tried to hack into the server. He even managed to make it send a mail from someone else's account, as far as I know. And he found a way to put a file into any account, which he shortly considered to use to put a shutdown command into autostart. But of course, I must be the great hacker.

Me: Oh, man, there are hooks for react-redux now? I don’t have to wrap components in a higher order component to get information from the redux store and dispatch actions? Could this solve the problem I’m having with data fetching and consistency in the app I’m working on?!

Spends entire Saturday writing a basic server, connecting to an mLab instance, filling said instance with dummy data, starting a create-react-app, writing a reducer, action creators, components, etc. just to test how useSelector(), useEffect(), and useDispatch() would work in an application that isn’t just a simple counter (why is it that like every example is always the counter example?!). Bonus, react-router now ALSO has hooks, so got to play with useHistory() and useParams()

Conclusion: Maybe. It does appeal to me to not have the cascade of virtual DOM that you always get nesting HOCs, but I’m also wary of appearing too willing to jump on it just because it’s the new thing.

Has anybody else played around with react-redux hooks? Your thoughts?

Also, yes, I know, not every app needs redux. It had it when I was brought on and I don’t really have the ability to change that implementation detail now.

A couple of years ago I was working on a fairly large system with a complex (by necessity) access control architecture.

As is usually the case with those projects, it's awkward for developers to repro bugs that have to do with a user's accesses in production when we are not allowed to replicate production data in test, let alone locally.

We had a bug where I ended up making myself a new row in the production database for a thing I could have access to without affecting real data to repro it safely. I identified the bug so I could repro it in dev/test and removed the row and ensured everything worked normally, whew scary.

Have you ever walked into the office one day, and everyone is hunched over in a semicircle around one person's workstation, before one turns around to look at you and says - after a pause - "... ltlian?.."

Turns out I had basically "poisoned the well" with my dummy entity in a way where production now threw 500 for everyone BUT me who had transitive access to this post-non-entity. Due to the scope of the system, it had taken about a day for this to gradually propagate in terms of caching and eventual consistencies; new entities coming in was expected, but not that they disappear.

Luckily I had a decent track record for this to be a one-off. I sometimes think about how I would explain testing in prod and making it faceplant before going home for the day, other than "I assumed it would be fine". I would fire me.

So in the project I’m working on we were about to do a push to live, no major functionality just minor adjustments and nice to have stuff. One of the things I did was a reminder, nothing special just sends an email out if something hasn’t been done for 3 days and then sends an email every day following. Push to live and every thing goes fine with no issues. Day 1 there are no issues. Day 2 there are no issues. Day 3 and I’m inundated with people telling me that the emails are getting sent to practically everyone, shit. What have I done? What have I missed?
So I start looking at the live database hoping for a data problem, no such luck. I look at my code looking for something blatantly obvious but nothing. I start replicating the data but I can’t reproduce this bug and it’s annoying the hell out of me. I checked one of the emails that the client sent to us more thoroughly and seen that it was sent at 07:01. This is odd as our webjob runs at 1am so I start looking at environmental factors and started looking at release management, more out of hope than expectation. I check the staging environment and see that the webjob ran at 7:00. Coincidence I thought, the webjob gets packaged on the release pipeline and everything in the database was dummy data anyway but I’d better check anyway. The database was an exact copy of the live database, turns out a “senior developer” wanted to sanity check everything by running live data through the code so he copied the database over. It was fine for the first couple of days but the data was now 3 days out of date triggering my email code and I get hit with the shit storm. I’ve never met such an incompetent developer in my fucking life, functions 700 lines long, classes that are over 20000 lines, repetition every where and the only design patterns he’s used is when he picks up a child’s colouring book. I can live with the fact that he writes code like someone on their first day of University But copying a database because he wants to “visualise” the fucking data is absolutely farcical. No wonder the project is fucked with a “developer” (in the loosest possible use of the word) is at the helm.

1 problem down, 3 more show up.
I love SQL.

In other news, client won't send data to utilize, so I must fill in dummy data.

How's your day?

Actually, it happened just before my current holidays.
I had prepared a whole system to feed and use a machine learning model. My colleague and some others had been working on a great thing, all encapsulated, all abstracted for my system.
My last day at the office, they had it ready.
I install their thing, load one model and launch one dummy prediction: error. I try with other input data: error
I try debugging a bit more, errors all the way. Knowing them, I asked if they wrote some unit tests.
"Sure we did"
I find the tests, yes there are some. And I notice:
"Hey, I see that in all your tests, you're making more than one prediction at a time (=aka using a matrix with more than one row)
- yeah, and it work fine
- in the project, we're doing one prediction at a time, did you try it with one prediction?"
He tries: error, that was totally what I said.
I started ranting on loosing the scope of the project, why we do tests in the first place.
Then, I grabbed my coat, said "see you in one week" and let them rework their code.
I was so angry at them, it seemed so basic to just check that 👹

2 years back when I was onshore, we were in the bad situation due to the size and complexity of handling big webserivces simulators. A single change makes the build red hence the face of other developers too.

These simulators were created using J2EE and VM templates 5 years back. With the time, application and data size grown. We were supposed to maintain consistensy in dummy data accross the applications. But some programmers made a copy of these simulators to finish their applications fast and made the situation worst.

Finally one of the team member dare to use stubby4j to solve this problem. Choosing the stubby4j was a good decision as it was the specialized tool written to create simulators only. But as the stubby4j was not having all the features a simulator need, he customized it's build for our simulators. All the team members were happy.

After few weeks, I picked a story to transform other simulators using stubby4j. The story was previously closed as it was hard to implement in stubby4j. I ingonred the comment and started working on. I spent 2 weeks but couldn't solve the problem. I read the comment in between but It was very late to take the step back. I was not able to give proper status update in the daily standup. Other team members (working from offshore) were thinking that I'm just passing the time. However my manager handled the situation very well and asked if I need some help.

This was friday, I took the leave as it was my wife's birthday. We couldn't go out due to the bad weather. I was thinking about the code all the time. Hence I started to write a new utility to handle all the requirement a webseervice simulator need. I took 2.5 days to complete it. On Tuesday, I demoed it to the whole team. And published it as an opensource application "STUBMATIC". In few weeks I received the good response from other teams as well.

I'm a full time open source developer now.

How do you guy (think of) prototype UI?

I have used the pen and paper approach but when you add the interactions such as clicks and animation on the paper,it become messy.

I feel that coding up a full blown front end for prototyping is overkill. Because when you want to prototype the list , you also need to insert the dummy data in order for you see probably clicks and drag animation.

I didn't know Toyota also pushes production code with dummy data

Why do people have to have surnames like "Test" and "Sample"? We even have a contact record for an organisation called "Testing Circle", Circle being the name of one of our service providers, but this other organisation is unrelated and genuine.

And here I am again, reading test cases that basically boil down to:

$testCase->foo = "bar";
$this->assertEquals($testCase, "bar");

$testCase2->foo = null;
$this->assertNull($testCase2->foo);

Why would anyone feel the need to write these kind of tests? They don't do anything. If I set up my mock a certain way, of course I will have that data, esp. if the unit under test only applies the data AS IS. (Funily enough through another component that already has the relevant dummy tests in place making these tests extra redundant and obsolete.)

You would think that one test case with dummy data suffices, yet no, there are like 30 examples that lie to you about apparent business logic cases, yet in the end the way you set up the mock decides what you will or won't get.

What's the point?

Ok story number 2, this one takes place back when I was at Uni.
We had a group project where we had to make a basic website. Nothing fancy, just basic HTML/CSS/JS.
We were a group of 3, one of the guys did a fairly good job with the CSS, he made a really good looking banner/footer and a kind of ‘featured’ page which looked awesome.
But the other guy... his contribution was the ‘contact us’ page, which consisted of a totally static table with dummy info and an embedded Google map showing the location of our fake car dealership.
Meanwhile I wrote all the Javascript, complete with a fake in-memory database containing our car data for displaying on the home page. Even had basic filtering. I made sure to mention in the peer review that I felt like he could have done more.

Don't leave "broken windows" (bad designs, wrong decisions, or poor code) unrepaired. Fix each one as soon as it is discovered. If there is insufficient time to fix it properly, then board it up. Perhaps you can comment out the offending code, or display a "Not Implemented" message, or substitute dummy data instead. Take some action to prevent further damage and to show that you're on top of the situation.
We've seen clean, functional systems deteriorate pretty quickly once windows start breaking. There are other factors that can contribute to software rot, and we'll touch on some of them elsewhere, but neglect accelerates the rot faster than any other factor.

Make your code available for your team members, please.

So we're working on this robotics project using ROS, a framework that enables multiple nodes in a network exchange their functionality among each other through tcp connections. Each node can be implemented and executed on your own machine, and tested with dummy inputs, but in collaboration they make a robot do fancy stuff.

The knowledgebase needs data from the image processing unit, providing this data to others with semantic context to high level planning, which uses this semantic data for decision making and calling the robot manipulation node with meaningful input, to navigate the robot's components in the environment. We use a dedicated machine, which pulls the corresponding repositories and is always kept configured correctly, to run each node, such that everybody has access to each other's work when needed.

So far so good. We tried to convince the manipulation guy (let's call him John) to run his code on our central machine, not a week, but since the first day, 5 months ago. Our cluster classification has been unavailable for 2 months, but my collegue fixed that. We still can't run the whole project without John's computer. If his machine blows up we're fucked.

Each milestone feels like a big-bang-test, fixing issues in interfaces last-minute. We see the whole demo just moments before our supervisors arrive at the door.

I just hope he doesn't get hit by a truck.

When you enter dummy data to the dev db and your boss tells you to use it in prod 👎

Me (Km) - I develop android applications in my company.
TM - Dumbest technical manager taking care of backend for company products(app).
PM - Product Manager

Incident - PM went to some event to give demo on our App but due to some backend issue there was wrong data for his account. PM reported this TM. And the conversation between Me and TM went like this.

TM : Km app is not working for PM, its not showing anything to him.

Me : Okay let me check...

I logged in with PM credential and checked the logs and i found that there was some error message saying that there was no data. I copy-pasted the error message to TM.

After few minutes (TM added dummy data to PM account)...

TM : Km app is working now, what was the issue for not working previously ?

Yes she asked me like this even though it was related backend issue.

Me : Its backend issue...!

TM : But I did'nt change anything at backend.

Me : Neither I, I did'nt build new APK and uploaded to Crashlytics Beta and he(PM) is not using new build.

I copy-pasted the previous error message again and asked her (TM)

Me : Why was this error message coming ?

TM : There was some wrong data for his account, So i added some dummy data.

Me : (FacePalm) How come its not called as change in Backend.

The worst part is TM still thinks it not a backend issue.

Help me out a bit, functional programming fans!

I'm experimenting with functional programming through JavaScript.

I created some dummy data to experiment with and created a simple function to query the data. I would like to get all elements, whose type attribute is not 'x'. A simple solution can be seen under the 'original code' part.

Under the 'fully functional code' part I gathered some frequently used general purpose functions, which I assembled into the function composition at line 45.

I'm having a bad taste in my mouth and feel that I've gone too far. I basically replaced every language element for a function. Is this the goal of functional programming? Is this how a perfectly functional code should look like?

tfw you're learning a new library and a function gives an error suggesting xyz in data. You assume you're using the function wrong. 5 hours later...turns out there is xyz in data ya big dummy!
