Welcome to LearnProgramming!

Why do some believe that using "Asynchronous I/O + Direct I/O" instead of "Zero-Copy" is better for efficiently transmitting small files?

I don’t have to pursue it professionally, but as a hobby, it seems interesting to me. Is it even possible to learn it if you have no prior knowledge and literally have to start from scratch? If so, where do you begin?

Some might find this question silly, especially those in the profession, but since I’m curious I have nothing to lose.

Please give honest course review

Need dsa sources to learn in c++

Hi,

I am good at the basics in python and also writing code on my own for my projects (with little help tho) but the problem is i usually go by brute force method for logics, they work but not really efficient (and also I tend to make my logics a bit complicated, I understood this by seeing other people codes being a lot simpler for same problems), . I need help in improving my coding skills and improve my thinking in implementing logics.

Any good resources or practice tools or a plan for where to start and how to go would really be helpful.

Thanks!!

I've got my final exam in programming basics coming up soon, it's open book given that you don't use AI and all of your recourses are local and don't require the internet to be accessed.

I'm just looking if anyone here has or knows a C cheat sheet that covers stuff like output format and storage class specifiers, reading/writing files, most useful functions and how to use them from the most common libraries, ect. before I go on to make my own

[Excuse my bad english]

Hello!

I'm currently a programmer who knows how to use C#, Java, JS, C, C++,Lua.

Not exactly a master at them tho.

Anyways, my goal is to improve solving skills as I'm pretty poor at it, and I've tried brilliant but alot of the courses require money, and I need a free interent source.

This is my code

```

```

I need some insight. I am a beginner and if I get stuck on a problem in my projects even with countless searches, I paste the error code to LLMs and make it explain to me why it happens. I try to see what is the reason and go find the solution myself. If I still can't, I make it suggest solutions for me. Is that an okay approach? or will it hinder my learning process?

I'm quite new to nextjs and the concept of csr, ssr, ssg... From my understanding, when a nextjs application is created, it creates and uses its own server to handle server side rendering. I also understand that it is common to use nextjs completely for the frontend and backend of an application.

But how would you use, let's say, a custom Express.js as the backend? Would ssr still work with the express server that would essentially be replaced the out-of-the-box nextjs server? Or is it common for developers to deploy and use both the servers, allocationg the nextjs server to performing ssr but using the express server as your main api?

A.I.s can be helpful learning tools when used properly but at the same time they can also be detrimental for our learning progress especially when we rely on them too much. I have been using ChatGPT to help me understand lessons that seem too complex for me to grasp. I would ready through and try to understand the lessons. I would then ask ChatGPT to break down and simplify the lesson's contents and then give me some practice exercises to ensure I understand the concepts. I don't move on until I know for sure that I have a good grasp on the current lessons. Is this considered cheating and detrimental to my learning progress?

Newb question. But struggling to understand when to use the different selector types. Probs just need more practice to get it memorised, but does anybody have any other tips, useful hints on how to get this simplified in my mind! (.), (#) etc etc

I am 15 years old and I would say that I am at an intermediate level with Python. I'm trying to become very good at it, while also becoming familiar with other languages. Which steps do you think I should take to improve, I have thought about taking Harvard's CS50 or their Python programming course.

I have spent 7 years doing Angular FE, C# BE, SQL Database.

I am debating what BE process I should do and replace with if any. Currently I am starting a new project using React as the FE for website and application deployment. I have in the past enjoyed using ABP Framework for C# on BE.

My problems now I would like to improve:

-If I stuck with ABP, upgrading ABP is a pain or least on previous versions it has not been super exciting to deal with ever.

-Improve processes of adding Roles and Permissions in BE.

-Speed up the process of demoing new features if possible.

-I really liked using ngswag with Angular to automatically give me api proxy so that I did not have to write services manually in FE. This is a side topic but just a thought to consider depending on my BE route I take.

I am debating the following options:

-Continue using ABP Framework

-Choose a new other option

-Headless Drupal CRM (friend suggested it but do not want to use php)

-Headless JS/TS CRM (Strapi maybe)

-DNN or Evoq

My main goals would be to have:

-Authentication JWT

-Roles

-Permissions

-Public API

-Dev/Test/Prod instances for BE

-Ability to still be able to create custom functions like any normal case in C#, like maybe fetching a list of cars, then filtering the cars, pagination of cars, storing images of cars. Just random things I would write in the BE I thought of.

-LTS of course for BE choice

Say you have two request methods, they each use a request object {a, and b} that's almost identical to the other, only their composition differs by an object property that's a similar name but two different objects.

So a has properties, one of them being fProp custom The properties on b match exactly those of a, but instead of fProp custom, it contains xProp custom.

My idea was to just make the two classes, a, and b inherit from a base class that contains the similar properties, only a specializes in fProp custom, while b specializes in xProp custom.

Before I even call any request method, I use one method that builds up the request using data shared by both, so I build up the base calss. This method eventually designates which request method to call, I can call aRequest using the a object, or bRequest using the b object. When I specialize, I call a function that combines the base class' values I've built up, and either fProp or xProp to build either the aRequest or bRequest. Then, I send them along their respective request method.

For some reason, this feels clunky? I'm leaning towards class a and b just being two separate models that just happen to look almost the same. This way, my method just builds a payload of common information and finally builds the request object when we specialize.

thoughts?

I used llms all the time to help me. My teacher is against it due to hallucinations. He said that theres no coding problem that cant be solved by googling. I am only aware about the things to look out for is checking when the stackoverflow ans was posted n make sure its not too long ago

I have a Java JSP Servlet web app running on Tomcat. Why is it that when I restart the Tomcat server, everything starts working again? For example, I might be able to log in successfully right now, but after some time, I can no longer log in with the same credentials due to a "wrong credentials" error. However, when I restart the Tomcat server, I am able to log in again

What have you been working on recently? Feel free to share updates on projects you're working on, brag about any major milestones you've hit, grouse about a challenge you've ran into recently... Any sort of "progress report" is fair game!

A few requests:

1. If possible, include a link to your source code when sharing a project update. That way, others can learn from your work!

2. If you've shared something, try commenting on at least one other update -- ask a question, give feedback, compliment something cool... We encourage discussion!

3. If you don't consider yourself to be a beginner, include about how many years of experience you have.

This thread will remained stickied over the weekend. Link to past threads here.

I want to make an easy coding project for him as a thankyou but i want to make it a bit funny aswell. My comp sci teacher helped me sm throughout the course and also would talk to me about random stuff. He also helped me with physics problems. Please give me some ideas. Btw I am gr 11 and i was learning java with him but i could also create a website.

Hi folks (I currently have a non-STEM degree), is it possible to take github computer science courses and transfer them or use them as a prerequisite to gain admission for a masters program in computer science or any other related discippline? Have any of you done this before? thanks

I have this code that shows an icon in the browser: My doubt is if this icon can be modified to have it to my liking (its color, its size, if I want to put text inside)

If it is possible, is it by means of code or do I need an editing software like Photoshop?
I copied this code from the Internet, and I have never handled these tags before. I was looking for ways on how to insert icons to a web page.

Hey guys, so i am about to enroll computer science degree major in software development. I was wondering what are the things that i can or should do while studying my degree to better prepare myself and increase myself of landing a job after graduated? Any tips and advice are appreciated. Thank you in advance.

My skillset needs updating, since I have been building .Net form-based apps for the last 15 years. What is accepted as the best platform for new front-ends today? Given how much effort is required for setting up a web server that is secure from attack, am I better off just moving towards a newer form-based front end platform?

Hello!

A brief introduction. I go by Wulfen, currently in my last year of pursuing a bachelor's in Computer Science. Through my previous years at an online university I have learned that a degree is just not enough to get hired. You need some practical work to show potential employers what you are capable of, and I am looking to really get into the mindset of making a good portfolio for future employers.

I want to learn Python - and I consider myself intermediate at best, and I want to find a partner (or some partners) to learn together and build skills with. We will start with Python from the ground up if needed, and do some coding exercises together from websites like hackerrank, or codewars. We will exchange best practices, logic strategies, and support each other where one may be stuck.

As for the requirements, all I ask is that you see yourself learning at least for the immediate future (half a year or a year from now), have the dedication and willing to put the effort and at least an hour or a couple of hours a day. Timezone, age, and other things like that are really not important.

I have created a discord channel which is valid for the next 7 days - https://discord.gg/7RaPVRtD

Ideally we would be around 2-10 people.

Please feel free to join and we can start organizing after the link expires!

I am excited to learn together!

I'm great with maths and have been a programmer for years, my next step is to learn AI.

Else can anyone recommend me a video going into AI, Deep learning, Machine learning (I learn best with videos) and such?

Thanks!

I’m really surprised how it is not heard at all. I’ve been doing their react course and it’s really good. If you are starting react do check out scrimba.com

Would greatly appreciate any help connecting to a database right now, I've read the docs and cannot figure out what is wrong. Attempted Stack Overflow and it wasn't terribly helpful.

Here's some of my code. I'm attempting to connect to MongoDB. I have data in there and it's ready to be accessed.

mongoose   .connect(process.env.MONGODB_URI)   .then(() => {     console.log("connected to db");   })   .catch((err) => {     console.log(err.message);   });   

MONGODB_URI=mongodb+srv://<MYNAME>:<MYPASSWORD>@cluster0.8dmao.mongodb.net/?retryWrites=true&w=majority&appName=Cluster0

If something has been wrong, it's thrown up the err.message, but otherwise it doesn't console.log anything, and then doesn't connect. What am I doing wrong? Can provide more code if needed. And any help is always appreciated.

I am a full-stack developer with 6 years of experience- and very proactive and passionate about it "At WORK" enjoy solving issues- making things work and vibe in my seat to my R&D periods. And I was lucky enough to switch work 3 times, one of them as 6 months mission contract- so very things are stable.

Now the question is- an abundant number of recruiters would require proof of concept on git profiles and portfolios which is understandable- However, I'm in a position where I'm at a disadvantage- I have the competency at work- but to prove it to recruiters requires me to provide hours outside of work dedicated in that as an "Investment"- but the time I allocated or the lack of thereof is not enough- and I'm aware of that.

I'm just wondering is just me in the Dilemma- where I enjoy the profession but not enough to make git contribution nor create or have ideas about "useful" projects. I do some R&D there for sure- but often recruiters focus on fully running the end products.

I work my hours with love- I enjoy it, then enjoy life- learning is one of them, but not enough to attract or be relevant to recruiters. Especially when you're a full-stack developer but most of your 6 previous projects are Data analytics related projects as a hobby.

The Dilemma.

I started learning how to code a few years ago, but I didn’t take it seriously at first. I built some small projects by following YouTube tutorials but never truly mastered the fundamentals. Then I stopped coding for a while, and when I came back, AI tools were everywhere. I started using them daily for learning and projects, which, in hindsight, was a huge mistake.

Now, I can read and understand most of my schoolwork (high-level languages, not full codebases), but if you ask me to write something from scratch, I can’t. I don’t remember syntax well, I don’t know what steps to take next, and I feel like I’ve lost my ability to think through problems without assistance. I know how to use pseudocode, but when I try to translate it into actual code, I get stuck.

I feel like I’ve become too reliant on recognition rather than recall. I can read code easily, but I struggle to write it, and it’s frustrating. I want to break out of this and become a strong, independent coder.

What’s the best way to relearn coding properly? Should I go cold turkey on AI and stick only to documentation? How do you guys approach learning in today’s environment?

I still have two years left in college, and my goal is to become an elite coder. Any advice would be greatly appreciated.

Basically the title, however recently I really wanted to learn a programming language and I’m willing to learn more but I’m having trouble looking for good resources to learn and also sometimes I feel intimidated that there are so many things TO learn that I wonder if I’m investing my time correctly on the current thing I’m practicing, im watching a YouTube tutorial that’s six hours long and everyday I practice every topic in there I’ve already gone through an hour of that video from the YouTuber Bro code and his c++ video, but I hope someone with professional experience can help me out or anyone well versed into the world of programming , I would very much appreciate it.

    I was considering going to college due to a more structured learning environment even though I know I can be self taught at home it’s currently really difficult for me and I’m hoping it’s just because I’m new to programming, also one of the main reasons I wanted to start programming was because I wanted to make video games but if someone has suggestions I would very much appreciate it thank you.
