update on my previous rant about not being able to solve the task, after having spent nearly 30 hours along the weekend figuring shit out of my code...
as i let my code run on the uni server to check for my points i gained, the output of the solutions always began on a wednesday, so i thought it was obvious all tests began on wednesday ... just the night before the deadline a friend of mine came to me and said he had randomly found out from someone that there was also a Tuesday ... as i heard that i implemented the additional day ... 245 against 220 minimum🤦🤦🤦🤦🤦🤦🤦
you can't imagine the pain i went through😩, i even thought about changing from CS to something different because of the incompetence i felt before succeeding😖😭
well fuck me, just spent the whole weekend (about 33 hrs) not being able to solve a task from uni with a java program we had to write🙄😪
the problem was a given set of movies with a weekday, the begin time, the duration, the title, and a "score"
the movies take place in one week (random days, random amount of movies) and every movie can be shown multiple times
our task was to find a sequence of non-overlapping (all unique) movies with a score of at least a given number
all in text form
i tried dynamic programming but the more i tried, the more it got complicated, so i ended up using "earliest finishing time first"
my code is just 3 points under the goal and i don't know what to change anymore😒, also some friends did the exact same and succeeded somehow
copying (and obfuscating) won't work, as the codes will be compared by a very good "copy checker"
let's hope i'll still have a chance for an exam😐2
longer rant, with curious question at the end;
my sister asked me lately how she can change the way her phone creates the name of pictures she takes (the naming scheme), as she didn't want the name to be composed of date and time (and so on) the picture was taken, cause she had to send it to her boss
after i replied that i don't know how this could be changed and that the naming scheme would have a purpose, she got angry at me because i wouldn't help her and that i should fuckin tell where it can be changed!😡
after i repeated my answer she said "what are you studying cs for?? YOU SHOULD KNOW THIS!!!😡😤"
i got furious, you guys can probably imagine as IT guy/dev 😠😠😠, given stereotypes/prejudices etc., unfortunately i'm not the guy who is good at freaking out and yelling at people, but GODDAMN IF I COULD TELL HER WHAT STUDYING THE DEGREE IS REALLY ABOUT! I'M SO FED UP WITH THIS!😤😤😤
i'm not supposed to know how her FUCKIN HONOR PHONE WORKS
WHICH I DON'T EVEN USE and never even thought about changing the naming scheme.
JUST RENAME IT AFTERWARDS!
of course her phone is so complicated that she doesn't even know how to rename the file, as she only knows how to use the google photos app (which doesn't support that?🤔) and never even considered to use the file manager ... well can't blame her for that, android isn't as simple as windows when it comes to this🤷
... in the end she just sent it, as is😪.
oh and by the way, is it actually possible?🤔14
just did a stochastic exam for my cs degree and let's say it didn't go very well (i'm not very good at stochastic)😒
had a question like: "how many possibilities exist if you divide 8 people into 2 equal groups of 4?" (with 5 different choices to answer)
shouldn't that be 8 over 4 (binomial)? so pick 4 people and 4 remain as the second group, that makes 70 combinations, as far as i know ...
but there wasn't any 70. I then divided by 2 so i got 35 which was one of the available answers🤷, is that correct? did i understand smth wrong?2
.... but first let me "npm init -y" and "npm i jest" (as the tutorial suggests) real quick in my git project ... whoops😯😐😶🤨 ... woah, ok ... 5000 added files, shit, dependencies 🙄... delete all ... git error😐😥
delete folder manually😪😅
resuming paused tutorial: "and if you've got a git repository, just install jest globally, do not do this in your repo!"
.... just happened to me😑😅2
my longest coding session was from 10am to 2am, so 16hrs
was in first semester of uni and we had to build the game "breakout" using a predefined guideline.
i had to program the collision detection of a ball against some blocks that had to be destroyed
took a long time for me to do the task, as i'm not the fastest coder (and often neither the smartest😅) and had to fight a bunch of bugs too.
in the end it kind of worked but the performance was horrible at best
when i look at the code structure of the project i work on with my friends, i always think about how to implement the SOLID principles of bob martin for clean code
... and then i think about the clusterfuck of almost unmaintainable code that has been created over time and all the unit testing that doesn't exist at all and how much time and effort it would need to correct that code and how i realize that i don't even understand the principles and how to implement them
... and then i give up and go on coding even more mess
... and then i repeat😅😖😩3
so my mum got a new phone yesterday (huawei p smart)...
boy will that be an adventure showing her what is possible now (coming from moto g3😅)🙄
but hey i'm a patient guy when it comes to that😏
the more i think about the structure i need to build, the possible combinations, the automation of describing all components, yada yada yada, the more i get this feeling it's becoming an NP problem ... or at least a very big algorithm😅😐
heard of nodejs that supports file handling, might try that🤔4
bought a windows license
built the pc
booted from usb
ask for license, put in bought license
installation seems normal
... windows isn't activated ... what?? how?? why is there a different key from the one i just entered?? and why does it still deny it when i try to change the key to my bought one?? y u do dis?😩
does anyone have an idea, what could be causing that?34
how hard can it be to make a section in html/css, so that it has a nice blurry background and a fancy title on it??😩
damn i've lost so much knowledge about html/css/js i can look up everything again😭 ... and i don't even know what to search for, that's how bad i have become😭😭13
when u see a bootstrap template use !important on multiple classes and id's u know someone kinda fucked up😅🙄5
have to use python and opencv for a uni project about lane detection in autonomous vehicles (just the detection with e.g. canny edge detection)
have begun to look into python in a 40min video seeing the differences between java and python, as i'm more comfortable in java....
well python is quite weird in its syntax but at the same time quite easy(?)
don't know what i should think about it 😕 as i'm used to the strict structure of java
any other good videos i can watch to get a better grasp of it?7
and another case of my parents discovering new technologies i alteady told them about:
my mum hast just found out about hyperloop, after watching on tv, and is like "wow omg that's incredible 😯😶🤔"
me thinking "well good you (finally) know about it, welcome to the future😅"
if i told them, they would be like "oh ok interesting" and then forget about it the next second😑😪2
after a long time i discovered that my nearest neighbours' son knows about CS stuff and another direct neighbor could potentially have a job for me to offer as a developer - and that neighbours' son is working for him.
what a freaking coincidence to finally have someone to talk to about tech who is not about a million miles distance and to also get a possible job in near future
i would say win-win for all of us😎😄1
whenever i tell my dad about a technology that is going way beyond our imagination and tell him about the consequences of it and how we should worry about that
then he watches some random tv show about internet security/cyber security and various algorithms (very abstract) which are currently changing the world and how we should care about our data and what the consequences of X technology is...
he be like: "oh is that true? that's interesting, how does that work?"
i'm like😑 dad, i already told you about that😩
ever had similar experience?2
happy rant 😄
just finished our group software project in uni (5 students, a way too complicated game) and just got the highest possible mark of all!!🤩🤩🤩
the project was focused on having a working, bug-free game, so yeah our game was UGLY AS FUCK😅 ... but 99% no bugs😎
best group in years😇
human-computer-interaction(is that the translation for Mensch-Computer-Interaktion?), we'll take our games and bitch about their usability and design😅
by the way i was responsible for the design/ux and did a kinda crap job because of too little time😐😅1
had a uni exam in databases (just closely didn't make it😒)
it didn't even have sql in it!?
questions about ER diagrams and draw a diagram, functional dependencies with given dependencies, find candidate key and what not, work on a b-tree (miserably failed😣), datalog (who the fuck cares about datalog? the least expected topic) and transaction management/serializability
whose idea was it to not include sql?? isn't it one the fundamental parts of relational databases?4
tl;dr: why is it so hard to build a pc?😒
why is it so damn hard to find the right pc components for developing/image editing/gaming/...?😟
i've been googling around and watched many youtube videos on what components to buy/what to watch out for/tips/problems/etc...
i want to build a decent pc for web, mail, office, developing, running linux as VM (for experiments), edit images, doing most in multitasking (and maybe also play some games) ... basically everything, but i can't wrap my head around what to choose😟
every time when i think (for example) "ok, ryzen 5 2400G, that must be it!' there's always smth negative about it, come on!!🙄😤
i wanted to make an AMD setup for 1000€ max
i feel like as a developer/"kinda it guy" i know what i need, then again i feel dumb as fuck, not knowing what to choose and i'm almost certain i will pick smth wrong😪
do u guys have any suggestions for me/any help?22
Dear god, tried to explain to my mum how to use a computer. Wait for spring creators update...😓
Everything went ... decent: learn opening different windows, closing them again, explaining functionality, which areas/buttons/etc.. are interactive ... and then comes the browser with its tabs😓
the only program which can open multiple "instances" of itself ... in itself. How to explain that? (i know that's probably not correct but that's the only way i can explain it) Needless to say she hasn't figured out how to use broswer tabs and what they are there for.
An now "Sets" come to windows. Oh boy how to teach that...?😥
... I'll probably just never show her just to keep safe😅8
Had a laptop on which i learned programming. bought a new convertible for uni, so i passed my laptop to my younger sister.
-> time to move data from old to new device. thought i didn't have that much data, mostly installed programs, so i thought alright i'm fine.
sister doesn't know how to reset so i do it ...
halfway through the reset process i realize i forgot all my programs i had written, including many java, a c#, and some written android apps i was kinda proud of ... plus my neural network i had finally finished with much struggle😥
there goes my history *poof* when i got worse in school 'cause of programming ... smth in me died in that moment 😑4
My dad needs my help with an excel sheet and calls me "Hey, need your help to do X, but this computer doesn't allow me to do, how can i do it?"
Me, who has already used skype, teamviewer and (Wahtsapp) video call several times (him too!) and got things done faster this way:"let's do a video call (whatsapp) so you can show me and i can help you better" (my dad thinks teamviewer is too complicated to use)
my dad "oh come on please, i don't have time for this, let's do it this way!"
After i tried to explain him that it would take far more time on the phone, needing him to explain what he sees, telling him the advantages of a video call right now, he ended like "ok forget about it!"
as he said that i kinda fell in a rage, quit the call myself and almost threw the phone against smth.
Seriously how hard can it be??? it's just few phone taps away😥, i would have even proposed to video call him myself to make things easier for him! But he prefers the classical-phone-way which every time takes half an hour just to understand where he's at.
It's just frustrating every time...2
My mum wants to learn how to use a computer. She wants to help my dad in his business in case something needs to be done and neither me nor my dad are (currently) available.
Will be .... a great challenge, since she didn't use a desktop computer almost ever, but i'm nevertheless proud of her and will try my best to help her😍😊😎10
How to convince someone that it's not helpful to delete apps running in background (RAM) on an android phone? it's like a habit for that person😌
says phone will explode with too much RAM being used and don't want apps run in background ... 😥
pls help for arguments16
A little reflection on the relationship between me/my dad/computer:
When i was younger my dad showed and taught me how to work on his (10 - 15yrs+ old) laptop running windows xp. Soon we got a simple desktop pc (those ones that took nearly a minute to start). i remember my dad sayin something like "don't download anything cause (the pc will brake/it will be a virus/...)", I don't remember exactly ... but i know that i still did it (being fucking nervous😅) and it went well😌. later me and my little sister would go to "spielaffe.de" several times until getting some kind of "virus"😅😅.
Time passed and i got passionate about pc's (programming, trying Ubuntu, reading about internals of a pc,...). It didn't take long that i passed my dad's knowledge and so here i am studying CS😎.
In the end, regarding my dad:
first he was the master i looked up to, then he became the buddy i talked to and asked for problems, then ... he remained the light user who would like to return to his windows xp era and asks me first as his personal google when something happens out of his "comfort-zone"😅😌.
And sometimes i believe my dad is becoming incompetent for pc's😂😅
different browsers rendering same things differently...
i have a slider with a given width of 7em. in edge it renders as i want it to, chrome fucks it up and makes it way smaller and display way off position and its parent div is way too big, firefox is somehow between those 2? all browsers are scaled to 100% 😥😒4
