In a user-interface design meeting over a regulatory compliance implementation:
User: “We’ll need to input a city.”
Dev: “Should we validate that city against the state, zip code, and country?”
User: “You are going to make me enter all that data? Ugh…then make it a drop-down. I select the city and the state, zip code auto-fill. I don’t want to make a mistake typing any of that data in.”
Me: “I don’t think a drop-down of every city in the US is feasible.”
Manage: “Why? There cannot be that many. Drop-down is fine. What about the button? We have a few icons to choose from…”
Me: “Uh..yea…there are thousands of cities in the US. Way too much data to for anyone to realistically scroll through”
Dev: “They won’t have to scroll, I’ll filter the list when they start typing.”
Me: “That’s not really the issue and if they are typing the city anyway, just let them type it in.”
User: “What if I mistype Ch1cago? We could inadvertently be out of compliance. The system should never open the company up for federal lawsuits”
Me: “If we’re hiring individuals responsible for legal compliance who can’t spell Chicago, we should be sued by the federal government. We should validate the data the best we can, but it is ultimately your department’s responsibility for data accuracy.”
Manager: “Now now…it’s all our responsibility. What is wrong with a few thousand item drop-down?”
Me: “Um, memory, network bandwidth, database storage, who maintains this list of cities? A lot of time and resources could be saved by simply paying attention.”
Manager: “Memory? Well, memory is cheap. If the workstation needs more memory, we’ll add more”
Dev: “Creating a drop-down is easy and selecting thousands of rows from the database should be fast enough. If the selection is slow, I’ll put it in a thread.”
DBA: “Table won’t be that big and won’t take up much disk space. We’ll need to setup stored procedures, and data import jobs from somewhere to maintain the data. New cities, name changes, ect. ”
Manager: “And if the network starts becoming too slow, we’ll have the Networking dept. open up the valves.”
Me: “Am I the only one seeing all the moving parts we’re introducing just to keep someone from misspelling ‘Chicago’? I’ll admit I’m wrong or maybe I’m not looking at the problem correctly. The point of redesigning the compliance system is to make it simpler, not more complex.”
Manager: “I’m missing the point to why we’re still talking about this. Decision has been made. Drop-down of all cities in the US. Moving on to the button’s icon ..”
Me: “Where is the list of cities going to come from?”
<few seconds of silence>
Dev: “Post office I guess.”
Me: “You guess?…OK…Who is going to manage this list of cities? The manager responsible for regulations?”
User: “Thousands of cities? Oh no …no one is our area has time for that. The system should do it”
Me: “OK, the system. That falls on the DBA. Are you going to be responsible for keeping the data accurate? What is going to audit the cities to make sure the names are properly named and associated with the correct state?”
DBA: “Uh..I don’t know…um…I can set up a job to run every night”
Me: “A job to do what? Validate the data against what?”
Manager: “Do you have a point? No one said it would be easy and all of those details can be answered later.”
Me: “Almost done, and this should be easy. How many cities do we currently have to maintain compliance?”
User: “Maybe 4 or 5. Not many. Regulations are mostly on a state level.”
Me: “When was the last time we created a new city compliance?”
User: “Maybe, 8 years ago. It was before I started.”
Me: “So we’re creating all this complexity for data that, realistically, probably won’t ever change?”
User: “Oh crap, you’re right. What the hell was I thinking…Scratch the drop-down idea. I doubt we’re have a new city regulation anytime soon and how hard is it to type in a city?”
Manager: “OK, are we done wasting everyone’s time on this? No drop-down of cities...next …Let’s get back to the button’s icon …”

Simplicity 1, complexity 0.

*Got a request for installing and configuring an online shop for a client*

Me: Do you have a web space already?
Client: No, I don't want to pay for it. (FYI: They only cost about 20€ a year)
Me: Okay, but free hosters are often slow and unprofessional. I really do not recommend using free hosting services.
Client: Doesn't matter, do it.
Me: *Working on the shop for several weeks, finally goes online*
One week later, client contacts me saying shop is offline. I realize the free hoster he used shut down their services (bankruptcy), resulting in the loss of about 90% of the work that I had done (no proper backups due to complexity)
Client: How can that even happen? You'll redo the shop, right?

Back in the day, I joined a little agency in Cape Town, small team small office with big projects, projects they weren’t really supposed to take on but hey when the owner of a tech business is not a tech person they do weird things.
A month had passed and it was all good, then came a project from Europe, Poland to be specific. The manager introduced me to the project, it was a big brand - a segment of Lego, built on Umbraco (they should change the name to slowbraco or uhmmm..braco somewhere there) the manager was like so this one is gonna be quite a challenge and I remember you said you are keen on that, I was like hell yeah bring it on (genuinely I got excited) now the challenge was not even about complexity of the problem or code or algorithms etc you get my point… the challenge was that the fucking site was in polish - face palm 1 - so I am like okay code is code, its just content, and I already speak/familiar with 13 human languages so I can’t fail here ill get around it somehow. So I spin up IIS, do the things and boom dev environment is ready for some kick ass McCoding. I start to run through the project to dig into the previous dev’s soul. I could not relate, I could not understand. I could not read, I could not, I could not. - face palm 2 - This dude straight up coded this project in polish variable names in polish, class names in polish, comments in freaking polish. Look, I have no beef with the initial guy, its his language so why not right? sure. But not hey this is my life and now I should learn polish, so screw it, new tab - google translate, new notes, I create a dictionary of variables and class etc 
3 days go by and I am fucking polish bro. Come at me. I get to read the previous devs soul through his comments, what a cool dude, his code wasn’t shit either - huge relief. So I rock on and make the required changes and further functionality. 

The project manager is like really, you did it? I am like yeah dude, there it is. Then I realise I wasn’t the first on this, this dude done tried others and it didn’t go down well, they refused. - face palm 3 -

Anyway, now I am a rock star in the office, and to project managers this win means okay throw him in the deep - they move me to huge project that is already late of course and apparently since I am able to use google translate, I can now defeat time, let the travelling begin. - face palm 4 - I start on the project and they love me on it as they can see major progress however poland was knocking on the door again, they need a whole chunk of work done. I can’t leave the bigger project, so it was decided that the new guy on Monday will start his polish lessons - he has no idea, probably excited to start a new job, meanwhile a shit storm is being prepared for him.

Monday comes, hello x - meet the team, team meets x

Manager - please join our meeting.

I join the meeting, the manager tells me to assist the new dev to get set up.

Me: Sure, did you tell him about he site?

Manager: Yes, I told him you knocked it out the park and now we just need to keep going

Me: in my head (hmm… that’s not what I was asking but cool I guess he will see soon enough -internal face palm 5 - )

New dev is setup, he looks at the project, I am ask him if he is good after like an hour he is like yeah all good. But his face is pink so I figured, no brother man is not okay. But I let him be and give him space.

Lunch time comes, he heads out for lunch. 

1hr 15mins later, project manager is like, is the new dude still at lunch.

We are all like yeah probably. 

2hrs pass 

3hrs pass

Now we are like okay maybe something happened to him, hit by a car? Emergency? Something… 

So I am legit worried now, I ask the manager to maybe give him a ring. 

Manager tries to call. NOTHING, no response. nada.

Next day, 8am, 9am, 10am no sign of the dude. 

I go to the manager, ask him what’s up. 

Manager: he is okay. However he said he is not coming back.

Fuck you. Stop asking time complexity or space complexity of functional code. No one fucking knows.

fuck time zones and time changes, why the fuck we don’t have one time on the planet and one date that is just day.
No month, no years - all the complexity would be gone, day wouldn’t have 24 hours but it would be something more precise, there won’t be a second

time that earth goes around sun is

365,25964 days

31558432896 milliseconds

we should start count time differently so it’s not relative in space time continuum, what should be relative is the mass

For context, I've been working for a couple years now with Rust, and, I have to say, the experience has been astoundingly pleasant. The language is both incredibly productive and meets each of my use cases and stipulations regarding speed, safety, and complexity. That said, I've come to beg the question, "what is the point of functional languages like Haskell?" To me, what seems attractive about Haskell is the inherent thread safety, and the added syntactic niceties of code written in the language. However, one must keep in mind, my experience with Haskell has been pretty limited, simply due to the massive learning curve that the language presents. Such a "learning curve" brings me to my central point: these days with languages like Rust which bring together the best from functional and imperative worlds, it seems like functional languages are becoming increasingly irrelevant. Let's face it: no sane person will choose to learn a functional language as their first language, outside of academia and mathematics, and OOP/OOP-like languages remain dominant in the space. So, why then, is Haskell any different? What benefit do languages like Haskell pose in the modern CS space that thread-safe, non-GC languages don't already provide?

I definitely made a channel in the dev Slack I'm in for algo practice with the description bigOHNOtation.

Reminded again why every professional developer should at least read and understand basic algorithms...

Colleague: I don't understand why this agregation query is so slow, the counting is on the DB.

This function used to work fine... Now it sometimes hangs.

Me thinking: why does everyone assume db has unlimited resources and computing power so everything should be quick (no time or space complexity)...

Maybe if everyone understood this stuff our code base wouldn't be so shitty from the start...

Not dev but, enough for the story. Had an assignment to create a hashtable for my DS course. Asked a friend how he managed resizing and the load factor
Friend= tablesize*50
Me= what...
Friend= space complexity what...

Do dev or engineer needs to know how the program works?. I mean that should they know about time and space complexity?
Till now my answer is yes, they should know. But i have met more than triple Dev's with absolutely no knowledge of complexity and they all are behind code quality.

Today I'm starting interviewcamp.io. I graduated from a 4-year university in California with a degree in computer engineering and have almost 3 years of work experience, but my god I am terrible at algorithms.

Big O (time and space complexity), recursion, Binary Search Trees, reversing a fucking linked list, etc. I need the boost and I hope the $250 a year for the material will help me get at least a $5k increase in salary when jumping to another company after the whole pandemic (or get a raise at my current job).

If anyone has any experience with them let me know. So far I'm 2 hours in and it is nice so far.
