Search - "tables done wrong"
-
Lads, I will be real with you: some of you show absolute contempt to the actual academic study of the field.
In a previous rant from another ranter it was thrown up and about the question for finding a binary search implementation.
Asking a senior in the field of software engineering and computer science such question should be a simple answer, specifically depending on the type of job application in question. Specially if you are applying as a SENIOR.
I am tired of this strange self-learner mentality that those that have a degree or a deep grasp of these fundamental concepts are somewhat beneath you because you learned to push out a website using the New Boston tutorials on youtube. FOR every field THAT MATTERS a license or degree is hold in high regards.
"Oh I didn't go to school, shit is for suckers, but I learned how to chop people up and kinda fix it from some tutorials on youtube" <---- try that for a medical position.
"Nah it's cool, I can fix your breaks, learned how to do it by reading blogs on the internet" <--- maintenance shop
"Sure can write the controller processing code for that boing plane! Just got done with a low level tutorial on some websites! what can go wrong!"
(The same goes for military devices which in the past have actually killed mfkers in the U.S)
Just recently a series of people were sent to jail because of a bug in software. Industries NEED to make sure a mfker has aaaall of the bells and whistles needed for running and creating software.
During my masters degree, it fucking FASCINATED me how many mfkers were absolutely completely NEW to the concept of testing code, some of them with years in the field.
And I know what you are thinking "fuck you, I am fucking awesome" <--- I AM SURE YOU BLOODY WELL ARE but we live in a planet with billions of people and millions of them have fallen through the cracks into software related positions as well as complete degrees, the degree at LEAST has a SPECTACULAR barrier of entry during that intro to Algos and DS that a lot of bitches fail.
NOTE: NOT knowing the ABSTRACTIONS over the tools that we use WILL eventually bite you in the ASS because you do not fucking KNOW how these are implemented internally.
Why do you think compiler designers, kernel designers and embedded developers make the BANK they made? Because they don't know memory efficient ways of deploying a product with minimal overhead without proper data structures and algorithmic thinking? NOT EVERYTHING IS SHITTY WEB DEVELOPMENT
SO, if a mfker talks shit about a so called SENIOR for not knowing that the first mamase mamasa bloody simple as shit algorithm THROWN at you in the first 10 pages of an algo and ds book, then y'all should be offended at the mkfer saying that he is a SENIOR, because these SENIORS are the same mfkers that try to at one point in time teach other people.
These SENIORS are the same mfkers that left me a FUCKING HORRIBLE AND USELESS MESS OF SPAGHETTI CODE
Specially to most PHP developers (my main area) y'all would have been well motherfucking served in learning how not to forLoop the fuck out of tables consisting of over 50k interconnected records, WHAT THE FUCK
"LeaRniNG tHiS iS noT neeDed!!" yes IT fucking IS
being able to code a binary search (in that example) from scratch lets me know fucking EXACTLY how well your thought process is when facing a hard challenge, knowing the basemotherfucking case of a LinkedList will damn well make you understand WHAT is going on with your abstractions as to not fucking violate memory constraints, this-shit-is-important.
So, will your royal majesties at least for the sake of completeness look into a couple of very well made youtube or book tutorials concerning the topic?
You can code an entire website, fine as shit, you will get tested by my ass in terms of security and best practices, run these questions now, and it very motherfucking well be as efficient as I think it should be(I HIRE, NOT YOU, or your fucking blog posts concerning how much MY degree was not needed, oh and btw, MY degree is what made sure I was able to make SUCH decissions)
This will make a loooooooot of mfkers salty, don't worry, I will still accept you as an interview candidate, but if you think you are good enough without a degree, or better than me (has happened, told that to my face by a candidate) then get fucking ready to receive a question concerning: BASIC FUCKING COMPUTER SCIENCE TOPICS

TL;DR :
"when i die i want my group project members to lower me into my grave so they can let me down one last time"
STORY TIME
Last year in College, I had two simultaneous projects. Both were semester long projects. One was for a database class an another was for a software engineering class.
As you can guess, the focus of the projects was very different. Databases we made some desktop networked chat application with a user login system and what not in Java. SE we made an app store with an approval system and admin panels and ratings and reviews and all that jazz in Meteor.js.
The DB project we had 4 total people and one of them was someone we'll call Frank. Frank was also in my SE project group. Frank disappeared for several weeks. Not in class, didn't contact us, and at one point the professors didn't know much either. As soon as we noticed it would be an issue, we talked to the professors. Just keeping them in the loop will save you a lot of trouble down the road. I'm assuming there was some medical or family emergency because the professors were very understanding with him once he started coming back to class and they had a chance to talk.
Lesson 1: If you have that guy that doesn't show up or communicate, don't be a jerk to them and communicate with your professor. Also, don't stop trying to contact the rogue partner. Maybe they'll come around sometime.
It sucked to lose 25% of our team for a project, but Frank appreciated that we didn't totally ignore him and throw him under the bus to the point that the last day of class he came up to me and said, "hey, open your book bag and bring it next to mine." He then threw a LARGE bottle of booze in there as a thank you.
Lesson 2: Treat humans as humans. Things go wrong and understanding that will get you a lot farther with people than trying to make them feel terrible about something that may have been out of their control.
Our DB project went really well. We got an A, we demoed, it worked, it was cool. The biggest problem is I was the only person that had taken a networking class so I ended up doing a large portion of the work. I wish I had taken other people's skills into account when we were deciding on a project. Especially because the only requirement was that it needed to have a minimum of 5 tables and we had to use some SQL language (aka, we couldn't use no-SQL).
The SE project had Frank and a music major who wanted to minor in CS (and then 3 other regular CS students aside from me). This assignment was make an app store using any technology you want. But, you had to use agile sprints. So we had weekly meetings with the "customer" (the TA), who would change requirements on us to keep us on our toes and tell us what they wanted done as a priority for the next meeting. Seriously, just like real life. It was so much fun trying to stay ahead of that.
So we met up and tried to decided what to use. One kid said Java because we all had it for school. The big issue is trying to make a Java web app is a pain in the ass. Seriously, there are so many better things to use. Other teams decided to use Django because they all wanted to learn Python. I suggested why not use something with a nice package system to minimize duplicating work that had already been done and tested by someone. Kid 1 didn't like that because he said in the real world you have to make your own software and not use packages. Little did he know that I had worked in SE for a few years already and knew damn well that every good project has code from somewhere else that has already solved a problem you're facing. We went with Java the first week. It failed miserably. Nobody could get the server set up on their computers. Using VCS with it required you to keep the repo outside of the where you wrote code and copy and paste changes in there. It was just a huge flop so everyone else voted to change.
Lesson 3: Be flexible. Be open to learning new things. Don't be afraid to try something new. It'll make you a better developer in the long run.
So we ended up using Meteor. Why? We all figured we could pick up javascript super easy.Two of us already knew it. And the real time thing would make for some cool effects when an app got a approved or a comment was made. We got to work and the one kid was still pissed. I just checked the repo and the only thing he committed was fixing the spelling of on word in the readme.
We sat down one day and worked for 4 straight hours. We finished the whole project in that time. While other teams were figuring out how to layout their homepage, we had a working user system and admin page and everything. Our TA was trying to throw us for loops by asking for crazy things and we still came through. We had tests that ran along side the application as you used it. It was friggin cool.
Lesson 4: If possible, pick the right tool for the job. Not the tool you know. Everything in CS has a purpose. If you use it for its purpose, you will save days off of a project.1 -
Our production database has tables that exist only to be recompiled into a single table. Like, one record across 4 tables. Each record is only for one other record in the other 3 tables.
I LOST 2 HOURS DEBUGGING IT BECAUSE IT COULD NOT RECOMPILE THIS FUCKING TABLE. FUCK! -
When you work on a project for months, the newly appointed tech lead says "we all (him, the boss and other colleagues not involved in this project) looked at your code and decided that it should be dropped and we are starting from scratch again....now I'm not against code review (which we never did) so I welcome the input but allow me to vent my frustrations about how this is being done. Also to have a review & verdict without me being present?
So I ask what was so wrong:
* You changed the database structure. Valid, I tried to make your db an actual db with relationships, so I added some foreign keys, delete fields that were never used, all because they told me to use an ORM.
* You used to much logic in setters, validation etc, valid again but this would be something we could look at and fix imho.
* You are passing classes in your constructor, valid I wanted to use DI to make unit testing possible. Ohh but I don't like unit testing so I don't see the point and it makes it to complicated was the response.
So not only was the project cancelled, the new iteration is being developed without me, I'm shunned from all meetings. Ohh and from what I see they are now using 5 tables instead of 25 and completely started the db model from scratch...5 -
When the service, platform or plugin is bought then the requirements as to why "we" bought it are created....WHAT ON EARTH COULD GO WRONG!??!!!!
I'm literally now going to be using their API, building a UI and feeding it back into our system where if they had someone who actually knew what we're trying to accomplish could have been done with some database tables............
I hate that mentality 'We need X oh look Company Y does it and look at their UI and features!...lets buy it...oh we also need A,B,C,D...thats ok bring in a dev he'll do it their Sales Guy says it can be done....
....coulda given you X,A,B,C and D if I was involved from the beginning, cheaper and quicker. But I digress here's the world's biggest bandaid.
