*yesterday*
Client: "Perfect! How did you do this so quickly?"
Me: "I used a library"
*today*
Me: "I'm still debugging. It will take some time"
Client: "Well, it has already taken too long...I can hear Mozart in the background. Maybe you need to go to a library to get some quiet and get it done fast. Visit the one you used yesterday."
Me: "Library?...Ah, I meant plugin...like, code...a library is a bunch of packaged code"

Is this the code life
Another scrum meeting
Caught in the the Node life
No escape from reality
Open your eyes
Look up to the screens and see..
I'm just a dev boy
Doing some debugging
Because there's warnings here
Errors there
Segment faults
Everywhere
Anytime you distract
Takes another hour from me
From me

*piano starts

Mama. Just committed a bug
Merge the branch to production
Did it fast for milestones
Mama. The repo has just begun
But now they going to throw the stack away.
Mama. U u u uu
Didn't mean to code in LAMP
But it's the only stack i know how to setup
In Ubuntu. Without docker
I really don't get vagrant

*piano

It's too late
My team is done
Some dev is working in Nepal
A UX dev. Now what is that?
Goodbye everybody
I've got to go
Gotta leave this lame meeting
And face the truth
Oh nooooo. I i interns
(they have questions)
I want to debug
I don't want to stay till 3 in the morning

*epic guitar

I see a litlle dev over there
Let's code review, let's code review
Did he do the last commit?
Coding in the white board
Very very frightening me
That's bug(that's a bug)
That's a bug (that's a bug)
What the f*ck did you do that?
Magnificcooooooo

I was just coding and nobody liked it
He was coding and nobody liked it, spare his some time to do his debugging

Easy man. Here go. Will you let me code?
A meeting. No,we will not let you code. ( let me code)
A meeting. we will not let you code. ( let me code)
A meeting. we will not let you code. ( let me code)
We will not let you code
Never never let you go
Never let you code, oh
No no no no no no no
Oh mama mia, mama mia ( dude, you've gotta let me code)
Screw you guys, I'm gonna code and commit. Commit. Comiiiiitt!

*epic guitar

So you think you can review me and spit in my eye?
So you think you can dump me and erase my branch?
Oh baby, cant do this to me baby
I've just have to log out.
I've just have to log outta here

*epic guitar solo

Nothing really matters
The users will not care
Nothing really matters
To them

Any way this code blows

THIS is why unit testing is important, I often see newbs scour at the idea of debugging or testing:
My high school cs project, i made a 2d game in c++. A generic top down tank game. Being my FIRST project and knowing nothing about debugging or testing and just straight up kept at it for 3 months. Used everything c++ and OOP had to offer, thinking "It works now, sure will work later"

Fast forward evaluation day i had over 5k lines of code here, and not a day of testing; ALL the bugs thought to themselves- "YOU KNOW WHAT LETS GUT THIS KID "
Now I did see some minor infractions several times but nothing too serious to make me refactor my code. But here goes

I started my game on a different system, with a low end processor about 1/4 the power of mine( fair assumption). The game crashed in loading screen. Okay lets do that again. Finally starts and tanks are going off screen, dead tanks are not being de-spawned and ended up crashing game again. Wow okay again! Backround image didn't load, can only see black background. Again! Crashed when i used a special ability. Went on for some time and i gave up.

Prof saw the pain, he'd probably seen dis shit a million times, saw all the hard work and i got a good grade anyways. But god that was embarrassing, entire class saw that and I cringe at the thought of it.
I never looked at testing the same way again.

WRITE IN C ('LET IT BE')
When I find my code in tons of trouble,
Friends and colleagues come to me,
Speaking words of wisdom:
"Write in C."
As the deadline fast approaches,
And bugs are all that I can see,
Somewhere, someone whispers:
"Write in C."
Write in C, Write in C,
Write in C, oh, Write in C.
LOGO's dead and buried,
Write in C.
I used to write a lot of FORTRAN,
For science it worked flawlessly.
Try using it for graphics!
Write in C.
If you've just spent nearly 30 hours,
Debugging some assembly,
Soon you will be glad to
Write in C.
Write in C, Write in C,
Write in C, yeah, Write in C.
BASIC's not the answer.
Write in C.
Write in C, Write in C
Write in C, oh, Write in C.
Pascal won't quite cut it.
Write in C.

I just released a tiny game for iPhone!

It's basically an attempt to mix 'Heroes of Might & Magic' and mtg.

In the screenshot my terminal says 'helloworld.cpp'. That's right, this is my first c++ program and I don't care how crappy you think this game is, I'm super proud of myself!

I've always worked in data science where managers assume I know how to code because there's text on my screen and I can query and wrangle data, but I actually didn't know what a class was until like 3 years into my job.

Making this game was my attempt to really evolve myself away from just statistics / data transforms into actual programming. It took me forever but I'm really happy I did it

It was brutal at first using C++ instead of R/Python that data science people usually use, but now I start to wonder why it isn't more popular. Everything is so insanely fast. You really get a better idea of what your computer is actually doing instead of just standing on engineers' shoulders. It's great.

After the game was 90% finished (LOL) I started using Swift and Spritekit to get the visuals on the screen and working on iPhone. That was less fun. I didn't understand how to use xCode at all or how to keep writing tests, so I stopped doing TDD because I was '90% done anyway' and 'surely I'll figure out how to do basic debugging'. I'll know better next time...

WASM was a mistake. I just wanted to learn C++ and have fast code on the web. Everyone praised it. No one mentioned that it would double or quadruple my development time. That it would cause me to curse repeatedly at the screen until I wanted to harm myself.

The problem was never C++, which was a respectable if long-winded language. No no no. The problem was the lack of support for 'objects' or 'arrays' as parameters or return types. Anything of any complexity lives on one giant Float32Array which must surely bring a look of disgust from every programmer on this muddy rock. That is, one single array variable that you re-use for EVERYTHING.

Have a color? Throw it on the array. 10 floats in an object? Push it on the array - and split off the two bools via dependency injection (why do I have 3-4 line function parameter lists?!). Have an image with 1,000,000 floats? Drop it in the array. Want to return an array? Provide a malloc ptr into the code and write to it, then read from that location in JS after running the function, modifying the array as a side effect.

My- hahaha, my web worker has two images it's working with, calculations for all the planets, sun and moon in the solar system, and bunch of other calculations I wanted offloaded from the main thread... they all live in ONE GIANT ARRAY. LMFAO.If I want to find an element? I have to know exactly where to look or else, good luck finding it among the millions of numbers on that thing.

And of course, if you work with these, you put them in loops. Then you can have the joys of off-by-one errors that not only result in bad results in the returned array, but inexplicable errors in which code you haven't even touched suddenly has bad values. I've had entire functions suddenly explode with random errors because I accidentally overwrote the wrong section of that float array. Not like, the variable the function was using was wrong. No. WASM acted like the function didn't even exist and it didn't know why. Because, somehow, the function ALSO lived on that Float32Array.

And because you're using WASM to be fast, you're typically trying to overwrite things that do O(N) operations or more. NO ONE is going to use this return a + b. One off functions just aren't worth programming in WASM. Worst of all, debugging this is often a matter of writing print and console.log statements everywhere, to try and 'eat' the whole array at once to find out what portion got corrupted or is broke. Or comment out your code line by line to see what in forsaken 9 circles of coding hell caused your problem. It's like debugging blind in a strange and overgrown forest of code that you don't even recognize because most of it is there to satisfy the needs of WASM.

And because it takes so long to debug, it takes a massively long time to create things, and by the time you're done, the dependent package you're building for has 'moved on' and find you suddenly need to update a bunch of crap when you're not even finished. All of this, purely because of a horribly designed technology.

And do they have sympathy for you for forcing you to update all this stuff? No. They don't owe you sympathy, and god forbid they give you any. You are a developer and so it is your duty to suffer - for some kind of karma.

I wanted to love WASM, but screw that thing, it's horrible errors and most of all, the WASM heap32.

So I had finished my work early in class and asked the teacher if I could do something on my laptop for the remaining half an hour.

I take out my laptop and immediately people start asking if I'm hacking.

3 people come and sit next to me and ask what every line of code means that I write. (I think they got underwhelmed real fast because I was debugging).

The teacher then comes into the room and asks what I was doing and I said just working on an app project. She explains to me that it is illegal for me to be hacking and I could get into serious trouble if I am caught. I facepalm and she says your disturbing everyone else get off of your laptop and read a book.

I left that class thinking is she even qualified, what is she thinking. Are you teachers the same.

I've been tasked to do website debugging.
For Internet Explorer 11.
On a Mac.
I have to use a virtual machine to get Windows on a mac just so I can test on internet explorer.
This mac is not fast.
This virtual machine is even less fast.
The internet explorer on this virtual machine on this mac is the least fast.
Even worse, this website is a pile of garbage. It's slower than my grandma.
My grandma is dead.
You can't get any slower than that, so I thought.
But then I got introduced to the result of making a wordpress site with over 300 pieces of media and 20 plugins.
If you are one of the people that's smart enough to stay away from wordpress: I assure you that it fucks your site up beyond repair.
So anyway, how was your day?

I've found and fixed any kind of "bad bug" I can think of over my career from allowing negative financial transfers to weird platform specific behaviour, here are a few of the more interesting ones that come to mind...

#1 - Most expensive lesson learned

Almost 10 years ago (while learning to code) I wrote a loyalty card system that ended up going national. Fast forward 2 years and by some miracle the system still worked and had services running on 500+ POS servers in large retail stores uploading thousands of transactions each second - due to this increased traffic to stay ahead of any trouble we decided to add a loadbalancer to our backend.

This was simply a matter of re-assigning the IP and would cause 10-15 minutes of downtime (for the first time ever), we made the switch and everything seemed perfect. Too perfect...

After 10 minutes every phone in the office started going beserk - calls where coming in about store servers irreparably crashing all over the country taking all the tills offline and forcing them to close doors midday. It was bad and we couldn't conceive how it could possibly be us or our software to blame.

Turns out we made the local service write any web service errors to a log file upon failure for debugging purposes before retrying - a perfectly sensible thing to do if I hadn't forgotten to check the size of or clear the log file. In about 15 minutes of downtime each stores error log proceeded to grow and consume every available byte of HD space before crashing windows.

#2 - Hardest to find

This was a true "Nessie" bug.. We had a single codebase powering a few hundred sites. Every now and then at some point the web server would spontaneously die and vommit a bunch of sql statements and sensitive data back to the user causing huge concern but I could never remotely replicate the behaviour - until 4 years later it happened to one of our support staff and I could pull out their network & session info.

Turns out years back when the server was first setup each domain was added as an individual "Site" on IIS but shared the same root directory and hence the same session path. It would have remained unnoticed if we had not grown but as our traffic increased ever so often 2 users of different sites would end up sharing a session id causing the server to promptly implode on itself.

#3 - Most elegant fix

Same bastard IIS server as #2. Codebase was the most unsecure unstable travesty I've ever worked with - sql injection vuns in EVERY URL, sql statements stored in COOKIES... this thing was irreparably fucked up but had to stay online until it could be replaced. Basically every other day it got hit by bots ended up sending bluepill spam or mining shitcoin and I would simply delete the instance and recreate it in a semi un-compromised state which was an acceptable solution for the business for uptime... until we we're DDOS'ed for 5 days straight.

My hands were tied and there was no way to mitigate it except for stopping individual sites as they came under attack and starting them after it subsided... (for some reason they seemed to be targeting by domain instead of ip). After 3 days of doing this manually I was given the go ahead to use any resources necessary to make it stop and especially since it was IIS6 I had no fucking clue where to start.

So I stuck to what I knew and deployed a $5 vm running an Nginx reverse proxy with heavy caching and rate limiting linked to a custom fail2ban plugin in in front of the insecure server. The attacks died instantly, the server sped up 10x and was never compromised by bots again (presumably since they got back a linux user agent). To this day I marvel at this miracle $5 fix.

How I met python
[long read but worth]

There's nothing wrong with falling in love with a programming language for her looks. I mean, let's face it - Python does have a rockin' body of modules, and a damn good set of utilities and interpreters on various platforms. Her whitespace-sensitive syntax is easy on the eyes, and it's a beautiful sight to wake up to in the morning after a long night of debugging. The way she sways those releases on a consistent cycle - she knows how to treat you right, you know?

But let's face it - a lot of other languages see the attention she's getting, and they get jealous. Really jealous. They try and make her feel bad by pointing out the GIL, and they try and convince her that she's not "good enough" for parallel programming or enterprise-level applications. They say that her lack of static typing gives her programmers headaches, and that as an interpreted language, she's not fast enough for performance-critical applications.

She hears what those other, older languages like Java and C++ say, and she thinks she's not stable or mature enough. She hears what those shallow, beauty-obsessed languages like Ruby say, and she thinks she's not pretty enough. But she's trying really hard, you know? She hits the gym every day, trying to come up with new and better ways of JIT'ing and optimizing. She's experimenting with new platforms and compilation techniques all the time. She wants you to love her more, because she cares.

But then you hear about how bad she feels, and how hard she's trying, and you just look into her eyes, sighing. You take Python out for a walk - holding her hand - and tell her that she's the most beautiful language in the world, but that's not the only reason you love her.

You tell her she was raised right - Guido gave her core functionality and a deep philosophy she's never forgotten. You tell her you appreciate her consistent releases and her detailed and descriptive documentation. You tell her that she has a great set of friends who are supportive and understanding - friends like Google, Quora, and Facebook. And finally, with tears in your eyes, you tell her that with her broad community support, ease of development, and well-supported frameworks, you know she's a language you want to be with for a long, long time.

After saying all this, you look around and notice that the two of you are alone. Letting go of Python's hand, you start to get down on one knee. Her eyes get wide as you try and say the words - but she just puts her finger on your lips and whispers, "Yes".

The moon is bright. You know things are going to be okay now.

So I wrote an application that loads data from a 3rd party API. It allows the user to enter a record locator number and pull it up. By design, the value can be a partial match and it will pull up the record still.

The first API call I make only took 2-3 seconds, so I didn't see an issue as it's loading most of the data the app needs. I keep the filters/fields as they are and move on.

Fast forward 6 months. The user is complaining that the records are taking 30-45 seconds to load. Sure enough, load times are terrible. I've made lots of changes to what fields I'm loading through the API, and I'm calling several additional APIs, so I start pulling pieces of code out to see if anything improves. They all barely make any difference--still 30+ second load times. I end up removing everything except the first API call I developed that was taking 2-3 seconds before. Still taking 30+ seconds.

The 3rd party API allows you to filter using "starts with" or "contains". I used "contains" initially and had no issue, but I decided to try "starts with" since it should fit most use cases.

Load time is less than one second. I add back everything else. Load time is just over a second.

It seems that the 3rd party updated the API and multiplied load times by 10 when using that particular filter. I spent almost an hour on this since the platform doesn't support performance or debugging tools very well, and it all came down to a one line fix.

It was the first time I worked on a big project with a big team, I looked at the given code and copied their code style.

I finished very fast and everything was working fine, was really proud of myself. I'd like to add some logging though.

Programm failed it was heavily async and parallel so 2 days of debugging had past the whole team was on board nobody knew what went wrong there.

As I stared into the darkness of my code I suddenly saw what went wrong 😂

As I adopted no curly braces style of the Team for

If (condition)
Justine();

And I added logging above without braces everything broke 😂 it was indented properly so as a heavily python user everything looked fine

"Yesterday "
Client: ''Perfect! How did you do this do quickly? "
Me: "I used a library"
"Today "
Me: "I'm still debugging. It will take some time"
Client: "well, It has already taking too long.... I can hear Mozart in the background. Maybe you need to go to a library to get some quite and get it done fast. Visit the one you used yesterday. "

Me: "library?Ahh... I meant plug in like.... Code, a library is a bunch of packed code. "

The $customer gets a device from us, with th wifi connected as specified in the order. $customer connects it to the mains and monitor, puts in the dongle and the connection is established.
Fast forward 3 weeks, now everything went south. The device does not connect to the network, the service is offline. Our first question: "Has someone modified the WiFi name or password?"
$customer: "No, there were no changes in the WiFi"

So the full arsenal of debugging the connection over LAN starts, interrupted by $customer unplugging the device "because he needs LAN now"

After sometime, we figured out, everything is fine with the device, and ask $customer once again, if the config $ssid and $password is correct.

$customer: "Oh, we changed the name to $ssid2 because it looks nicer, is that a problem?"

Internal: "Are you f*kin kidding me? I asked you exactly that"
Me: "Alright, that explains the issues. Please tell us in advance if you want to change something with the WiFi."

Debugging in real life

Our family is working on the house. We have an integrated floor heating system, which is connected individually for each room. (we have three rooms, only two are connected yet)

Today we changed the main water boiler. At first it seemed like it was working, but then we lost pressure. It dropped fairly fast so we checked every sink, every water outlet.

We just missed the unconnected floor heating pipe, that was connected to the main pipe...

Its a fucking mess down here, so dont complain about you bugs, I have experienced worse!!!

So I made an update to my React Native app. I changed UI of a couple of screen, added a few animations here and there, refactored how my graphQL resolvers work in the backend(no breaking changes), changed how data gets loaded into the database etc.

It worked in dev so I figured hey let's deploy it. Today is(was because it's now 3am but more on that later) a national holiday so no one goes to work so no one will use my app so I have an entire day to deploy.

I started at 15:00(because i woke up at 13:00 lol). I tested the update once again in dev and proceeded to deploy it to prod. I merged backend to master, built docker images, did migrations on the db, restarted docker-compose with new images. And now for the app. I run ./gradlew assembleRelease and it starts complaining that react-native-gesture-handler is not installed. Ugh, rm -rf node_modules && yarn install. It worked. But now gradlew crashes and logs don't tell me anything. Google tells me to change a bunch of gradle settings but none of them work. Fast forward 5h, it's around 20:00 and I isolated the issue to, again, react-native-gesture-handler. They updated from 2.2.4 to 2.3.0 which didn't fucking compile. 2 more hours passed (now 22:00) and I got v2.3.1 working which fixed the problem in 2.3.0 but made my app crash on startup. YOUR FUCKING LIBRARY GETS 250K WEEKLY DOWNLOADS AND YOU DONT EVEN BOTHER CHECKING IF IT COMPILES IN PROD ON ANDROID?! WHAT THE FUCK software-mansion?

After I solved that, my app didn't crash. Now it threw an error "Type errors: Network Request Failed" every time I fetch my legacy REST API(older parts use rest and newer use graphql. I'll refactor that in the next update). I'll spare you the debugging hell i went through but another 5h passed. Its 3am. My config had misspelled url to prod but good for dev... I hate myself and even more so react-native-gesture-handler.

what the fk how hard can it be to have a working version of the software on the master/ ros-version branch? Why is this thing always broken?! HOW?!

Had to update today unfortunately, and man, I have been "installing" this shit for over 3 hours now. Use the .install they said. It will be fast they said. Ye sure, my ass. The Dependencies are broken and incomplete as always and the tutorial is not up to date. Big suprise. I get it, it's a lot of work to keep these things up to date. But please if they are this broken and incomplete why are they released in the first place.
And then they wonder why I don't manage to do my work on time. Yeah, cause I'm stuck debugging this shit <.<'

@ everyone who keeps pushing Vue via node

Vue via npm:
- shit
- bundling so you can save 15% on car insurance
- webpack/etc to condense your 50TB node_modules folder
- have to deploy, if you're in the US then it'll probably be in the middle East or maybe North Korea if that falls out

Vue via script tag:
- works awesome
- pretty feckin fast
- can be deployed purely static
- easy debugging from dev console
- easy templating for frontend
- can use existing html/css
- easy to work in teams with people without having everyone install npm
- if you have a designer they will love you for making it easy to style things
- you can cache it and make it offline without any of the new bullshit vuex
- you can use vanilla libraries without a mixin, polyfill, bundler, or etc anus

So, do any of your poor fuckers have the opportunity - nay, PRIVILEGE of using the absolute clusterfuck piece of shit known as SQL Server Integration Services?

Why do I keep seeing articles about how "powerful" and "fast" it is? Why do people recommend it? Why do some think it's easy to use - or even useful?

It can't report an error to save its life. It's logging is fucked. It's not just that it swallows all exceptions and gives unhelpful error messages with no debugging information attached, its logging API is also fucked. For example, depending on where you want to log a message - it's a totally different API, with a billion parameters most of which you need to supply "-1" or "null" to just to get it do FUCKING DO SOMETHING. Also - you'll only see those messages if you run the job within the context of SQL FUCKING SERVER - good luck developing on your ACTUAL FUCKING MACHINE.

So apart from shitty logging, it has inherited Microsoft's insane need to make everything STATICALLY GODDAMN TYPED. For EVERY FUCKING COMPONENT you need to define the output fields, types and lengths - like this is 1994. Are you consuming a dynamic data structure, perhaps some EAV thing from a sales system? FUCK YOU. Oh - and you can't use any of the advances in .NET in the last 10 years - mainly, NuGet and modern C# language features.

Using a modern C# language feature REMOVES THE ABILITY TO FUCKING DEBUG ANYTHING. THE FUCKER WILL NOT STOP ON YOUR BREAKPOINTS. In addition - need a JSON parsing library? Want to import a SDK specific to what you're doing? Want to use a 3rd party date library? WELL FUCK YOU. YOU HAVE TO INDEPENDENTLY INSTALL THE ASSEMBLIES INTO THE GAC AND MAKE IT CONSISTENT ACROSS ALL YOUR ENVIRONMENTS.

While i'm at it - need to connect to anything? FUCK YOU, WE ONLY INCLUDE THE MOST BASIC DATABASE CONNECTORS. Need to transform anything? FUCK YOU, WRITE A SCRIPT TASK. Ok, i'd like to write a script task please. FUCK YOU IM GOING TO PAUSE FOR THE NEXT 10 MINUTES WHILE I FIRE UP A WHOLE FUCKING NEW INSTANCE OF VISUAL STUDIO JUST TO EDIT THE FUCKING SCRIPT. Heaven forbid you forget to click the "stop" button after running the package and open the script. Those changes you just made? HAHA FUCK YOU I DISCARDED THEM.

I honestly cant understand why anyone uses this shit. I guess I shouldn't really expect anything less from Microsoft - all of their products are average as fuck.

Why do I use this shit? I work for a bunch of fucks that are so far entrenched in Microsoft technologies that they literally cannot see outside of them (and indeed don't want to - because even a cursory look would force them to conclude that they fucked up, and if you're a manager thats something you can never do).

Ok, rant over. Also fuck you SSIS

Me: Ok, Lets continue with this scratch project. We need to script in a Update Alert (A button we can press to shut down the game and alert players ingame that an update is here), Add upgrades, (Yadda yadda yadda), And Debug the......

Assistant #1: How about lets not worry about Debugging the game and focus on adding more scripts.

Lead Assistant: How about lets Debug AND add the updates just like the developer said.

Just a word to Assistant #1. Number one, Debugging to a game is like cleaning, grooming, and feeding yourself. If you dont do it, the game performance is to be considered "F.I.T.A" or "Fucked In The Ass". it wont get anywhere Fast, Let alone get anywhere at all. Number Two, Updates are important, I admit that, and im not saying they are less important than debugging, but if you add an ass load of updates before you debug, it will take more time to debug ALL of those other updates than just the few we already did. Plus it will only add more stress to the developers which in turn may make us miss(or make) more bugs in development.

Keep in mind that we are developing Scratch Projects that use the coding language "Blocky".
