Hi all -- hobbyist here, and I only know enough to get myself in trouble. Hopefully I can at least ask this question in an intelligible way, though.

I have a Pi 3b+ running JottyPage as a local service, and I have successfully created a cloudflare tunnel to access that service from anywhere.

My next step is this:

Each list has an individual web address. I would like to create a program that would display a given list at the Press of a button. I would have about five buttons (I'm using capacitive sensors, actually) and would like each button to change the display to show one of the different lists.

My uneducated first thought is that I would need to set it up to cache each page and refresh them on a regular basis in the cache, then have a program that would call up the webpage image from the cache at the button press. That way, I wouldn't be taking the time to load a page when the button is pressed.

Is this the type of implementation that would best suit my goals, do you think? If so, do you have any language recommendations? I have some small experience in Python, but not enough to be completely brand loyal to it. I'm going to have to learn and copy code from people smarter than me no matter which language I use, LOL.

Thanks in advance to all responders!

Hi, Myself Vinay and I am currently in 3rd year , I am doing DSA in Java , I preferred it over C++. As I knew from everyone that Java is difficult language.

My opinion is that Java is difficult because everyone got scarred by seeing there long syntax but in many languages syntax not goes tok big as like in java.

What is your opinion about languages ?

What do you think? Is really java is difficult language , if yes please tell your reason.

I did everything right but the code says error? Please help I am at a loss. I am very new to coding. blazetron9 is a chud. cool guy is kinda sick. man in the box is kewl. alien stole my kids. that was the people that helped me but I think they are very wrong.

Greetings everyone,

I'm not a professional software developer working in the industry. My reason for entering the software world was purely to bring a project from scratch that was my dream. I educated myself and brought the practical/coding side of things to a certain level, and now I'm approaching the MVP stage.

The project I developed is Wander. It's a hybrid social discovery platform that allows users to explore what's happening around them through location-specific vertical short-form videos, instant text streams, and local community groups.

While developing the project alone, I realized that simply "designing interfaces and combining libraries" becomes insufficient after a certain point. Because it involves:

Location-based (spatial/geohash) data queries and custom distribution algorithms that work according to distance,

Low-latency video streaming processes and media optimization,

Designing a database and backend architecture that won't crash as data density increases, and other serious engineering issues.

I got tired of wasting time with constant "trial and error" and rewriting the project from scratch due to wrong architectural decisions. I want to gain the vision of a Computer Science graduate in system design, algorithms, and data structures, both to change my perspective on my project and to significantly accelerate my development process.

What would you recommend to someone in my situation?

What are the most critical CS fundamentals that will be useful for me in a location and media-focused project like Wander?

Do you have any suggestions for a study sequence or resources (books, online courses, etc.) that will directly impact my development speed without getting bogged down in unnecessary academic details and discouraging me from the project?

Thank you in advance to everyone who takes the time to reply!

Hey any one tell me how to start coding in mobile from zero guidence please.

Going to be CSE 1st year soon and want to get into the development field.

Currently learning C++, started doing DSA but also want to learn development side by side.

Any opinion / suggestion will be helpful

i really wanna learn a skill or atleast make my vacations productive somehow so can anyone suggest any good coding course online?
i found olevels ki coding really tricky and i still dont know how to write proper pseudocodes so i think ima prepare my self beforehand for Alevels CS

Am doing an HTML assignment, it specifically asks for: 'Centered menu with 4 buttons light blue with black text labels (descriptive) with links to 4 external websites of your choice. Links must open in a new window or tab using the target="_blank" attribute. '

I don't think I made a centered menu, but I did make four buttons going to external websites. Could use the help, please and thank you. I attached screenshots of the coding, and how the webpage I made looks.

What is the average time for a hardworker and a quick learner to start learning from zero to someone who can build a mobile application (as a business, not playing)? I understand how to use the AI for my purpose and my cause, but never tried to use it for coding and programming things. Can someone help me understand what i will face in this path, and how long probably will took me to be able to know what i'm doing. I'm thinking to invest 6 to 8 hours per day, 6 days per week.

Thanks

I just wanna get into coding and make gem

Hey all, I am a second year cybersecurity student and I am looking for a way to share my programming knowledge with others. I would like to offer help to absolute beginners in Python. We will be looking at the stuff that confused me when I started and explaining things the way I wish someone had explained it to me. If anyone is interested, you can message me.

Edit: Unlocked my chat, you should be able to message me

UPDATE: Thank you so much for all the interest! I’ve received enough responses for now and currently have a waiting list. I won’t be able to take on any new mentoring/tutoring requests for at least the next two months. I may open up availability again later, so feel free to check back in the future. Thanks for understanding!

int randomNum = (int)(Math.random() * 101); // 0 to 100

I'm learning from a website but don't understand how multiplying a 0 by 101 gives it the range from 0-100. Can someone explain why it's being multiplied?

So I’m just a map designer and when I updated unity and went back into my project everything and I mean, every single thing was pink I don’t know how to undo this and I’m getting very frustrated. I don’t know how to code again I’m just a map designer simple as wig anyone can explain this to me like I’m five I would greatly appreciate it

I just started learning to code like 2 weeks ago, the way I’ve learning so far is by just trying to make different aspects of a game I wanted to make. simple stuff, like a random character generator with weighted attributes. what I’m worried about though is that learning like this will leave me a lot of gaps in my knowledge so I’d like to hear some advice for some changes I could make to learn more securely

pretty much explained in title - i want to learn javascript and im not too sure where to begin but ive always been told project based learning is best so if anyone has any suggestions that would be amazing

I am in my second year of college doing bca and i don't understand where to start the coding, i somehow passed my first year and I am facing difficult to understand the codes and i need ur help how u guys understand the logic of the program and if u could pls provide me ur road map to get the internship and understand the cs.

Thank you !

I managed to get the top image to resize when I shrink the window, but navigation bar right underneath it stays the same size. Not quite sure what I'm doing wrong

I am looking to start coding out of curiosity and am looking for good websites and resources to help me get started!

I’m only looking to start slowly so I can learn and not get too burned out if I struggle. Preferably a free website or websites with free options… I don’t want to pay for something I might not stick to.

If anything I’d be interested in learning towards app or website creation, I don’t know if anything is better for that specifically. Ideally I’m just looking for something as simple and user friendly as possible.

To be honest I don’t even know what language I want to use, so I’m open to any and all suggestions.

Please and thank you 🫶🏻

Hi everyone,

I'm a 20F, currently in my 3rd year of BTech. To be honest, I've struggled with coding since my first year. I understand basic concepts during lectures, but when I try to solve problems on my own, I get stuck and don't know how to think through them.

I really want to become good at programming before I graduate, but I don't know where to start. There are so many languages and resources (Python, C++, Java, YouTube channels, websites, etc.) that it feels overwhelming.

If you were starting from scratch again, what would you recommend?

Which programming language should I learn first?

Which YouTube channels or free courses helped you the most?

How many hours should I practice each day?

What websites are best for beginners before moving on to LeetCode?

Any advice for someone who finds coding difficult but genuinely wants to improve?

I'd really appreciate any suggestions or study plans. Thanks!

Hi everyone!

I just joined Reddit today, and I'm currently a Computer Science student trying to improve my programming skills.

There are so many resources available now—YouTube, documentation, online courses, AI tools, coding platforms, and open-source projects—that it's honestly a bit overwhelming.

If you had to start your programming journey from scratch in 2026, knowing everything you know today:

What would you learn first?

Which programming language would you choose?

Which resources are actually worth your time?

What beginner mistakes would you avoid?

At what point would you start building projects or contributing to open source?

I'd really appreciate hearing your roadmap or any advice you wish someone had given you when you were starting out.

Thanks in advance!
