Welcome! Feel free to ask any questions regarding coding you have!

I am attempting to publish this project using Render instead of Vercel. Could you advise on what should be specified for:

"The relative path of the directory containing built assets to publish. Examples: ./, ./build, dist, and frontend/build."

Here is the project name for reference: Cruip Open React Template

im gonna start college in 20 days and i bought a mac for btech in cse. but i cant figure out the basics of vs code in a mac, it’s different than what it was ws in windows. is there any source from where i can understand how to work a mac especially for programming?

Hey. All my life I have been told to code but I haven't ever taken it seriously.

Now I am a sophomore in college in the Bay Area and I desperately want to make and ship my own products by my own code. I feel so shitty and helpless not being able to do any of this on my own.

Does anyone know where I can start? I am so willing to put the work and hours in to becoming technically skilled and being able to be a self sufficient coder and founder. I want to learn the skills of becoming a technical founder rather than a bullshit founder who needs to beg other software engineers to ship out my projects and ambitions. I know that the learning curve for programming is awful, is there any good place to start? I heard about C# or python being good.

My goal for this is to be able to ship my own websites and apps on the app store, as well as learning the backend etc. I am not in a rush of course I know I have time, I am not switching majors either but I passionately want to do this in my personal time to make the product ideas I have come to life.

Also does anyone know how long it should take me in consistently putting in 5-6 hours in a day of studying? Is that enough???

Here's the project on GitHub.

I have created a dockerfile. This works locally; I can build the docker image and run the app from it.

I am trying to use a GitHub action to deploy the image to dockerhub. Here's the workflow file, in which I am doing a checkout, setting up node, then using a build-push action from the marketplace.

The build-push action fails to execute the dockerfile when attempting to execute:

npm run build

Here is the error log:

I think I'm copying all the files correctly, but if I'm reading this right, it can't find index.html. That doesn't make sense to me, and StackOverflow/Google isn't helping me today. Can anyone point me in the right direction?

I am creating a program in Python that needs to compare a group of images. I want it to evaluate sports cards and determine if they are the same or not. What is the best image comparison tool to use for something like this?

I have tried OpenCV and GPT-4o-mini and neither are great at it.

Hi i am going to be in 2nd year of cs bachelor. I am looking for a window laptop around 1000$us that is sufficient enough and overspend my need.

16gb and upgradabe, 512ssd and upgradeble would be awesome cause I will be doing virtual machine. My need is well portable, the whole weight of laptop + charger shouble be below 3,2 kg. A dedicated graphic good enough for learning AI, my course doesnt focus mosly on AI but I still wanna do some small side projects about AI to get to know about this field, since i believe AI will be needed in every tech field in the future. I also occasionally play games, im not gaming all day, but if i have free time, I would like to play ofline games like minecraft, cyberbunk, assasin with avg 70fps in medium graphic, high graphic would be ideal! So would 3060 and 4050 rtx laptop be sufficient for my need? I often watch anime and read manga on my laptop too so I would like my screen to atleast QHD with 100% color accuracy stuff.

So what laptop would be a great choice for me, I have been having a headache of which one I need to get for a long time. I have looked through lenovo slim 5, 7, asus g15 many of them has great price and build but I dont know if I really need those build. Its my parents's money so I dont wanna overspend it. Any advice would be appreciated, thanks!

Pls pm me as I need help with editing game file (apex racer) I need to be level 800 and 30000 wins

I was hoping you all might have some innovative ideas for me.

I’m tired of manually inputting my extensive job history into these damn applications. I would much prefer romoving my genitals with a blunt object.

In this day in age I find it hard to believe somebody hasn’t come up with some script that would automatically input all of the info from my resume into an application.

i've tested my url several times, added all the required meta tags
but there is no way! whatsapp wont load anything as preview for my link!

Hi, my name is Sidd and I'm 15. I have been learning the basics of Python for about 1-2 years, so I am familiar with Python. Just recently, I also worked a bit with Unity C#. I made a game in a week, which I very much enjoyed. I also could understand C# pretty well.

I'm interested in coding, and I want to develop a career in it. I just don't know what path to take at the moment. I think it's best if I get a PCAP certification so that I have proof of my knowledge in Python. Does anyone have suggestions on what I should do? Should I go for certifications, keep building games/apps, or what should I do?

I’m trying to make an app (IOS and android ) for a project but have found it difficult to use react native. What is the best way to use it, where to learn and if there are better alternatives Thanks

I’d like to create a page for my website where people can put in the coat colors and alleles of parents and then have the possible coat colors of their litter calculated.

I can only find tutorials for contact forms and mathematical calculators but not an inbetween.

I’d appreciate help, thanks

Hi everyone,

I need your help. When a user clicks "Forgot Password" and enters an email that has not been registered, should I inform them that they are not registered, or should I tell them that an email has been sent to the entered email but actually send nothing in the backend? What is the best practice for security?

Thank you.

Hello, I have been wanting to make a paladarium with the want to use global weather reports to recreate an ecosystem with an on off switch.

So the basic idea would be for example If raining turn on rain system/fog Heat updates accordingly throughout day and night Lighting so it follows day night cycles etc

I've never used code and don't have a device to use nodes which is what people have suggested so I was wondering is the idea of using the updates of a website to create an on off system possible?

Hello i am a complete noob at coding I am on mac ,since vs studio is not working on mac anymore and alot of tutorials are using vs studio and are on windows even paid courses Where can i learn anything help thank you in advance

Do tech companies have any restrictions on branch? If I do my engineering from electronics field, will I be able to apply (and get) good software jobs (considering I have enough skills as par with a cs student).

I don't remember full content of the question

They are about mangoes and finding identical mangoes using functions , override and if-else:

Testcase one -> input_1 : 2 and input_2 : 2 but testcase output : 3

Testcase two -> input_1 : 1 and input_2 : 12 but testcase output : 1

The Testcase inputs must only entered in custom input , not in coding

I know basics in Java and python but the output is little confusing for me . Give your suggestions, answers and advice ?

idk if this goes here or not but can someone please help me title is self explinatory

Hiii again i have a question: as a data scientist which are platforms we need to master coding in , which will impress the recruiter like hacker , leetcode are these needed or do we have other sites for data science to showcase our coding skills

I need assistance from someone way more skilled than myself.

I am trying to get a direct link to my "Subscribe" or "Gift Subscription" button on my Kick Streaming page.
kick.com/ForeverEsoteric
I need it to assign it to a particular button on my website I'm putting together.

I have been able to figure it out on all other platforms, but their encoding is weird and looks WAY more complicated. Lol. I might just have been looking at my PC for too long, and should sleep... Anywho.

If you could help a girl out, that would be AWESOME!

TYIA.

I want to make a 2d fighting game or make custom characters for an existing one but I'm really bad at coding and I don't have much time to learn. I've tried mugen with fighter factory. Ive tried gobot and Roblox tutorials to no avail. I just want to make something small for my friends but I'm not sure how to start. And suggestions?

I have an image file of 970 images I'd like to make into individual flashcards. I don't know much about coding, I've tried and I can't seem to get this to work. If I could send someone a zip file of the images and could create the Anki deck for me, I would greatly appreciate it. Thanks!

I'm a beginner python programmer sometimes I feel like giving up because I don't get used to the intermediate concepts. Can anyone have any tips? I'm already on my final year of my college so I need to prepare for my placements too.

I'm someone who only knows LaTeX and I have this template that I have made that I have tried to make be formatted like how a professional would type his code blocks and code formatting:

And I am trying to format everything that can be done in code block for correctly. Though I am not sure if the way I do things are even right. Could someone please critique the way that I do things, please help me 'properly' do LaTeX? I want to build good habits incase I ever learn another programming language.

8 keep someone to help me understand what this is. And why someone would have it. I need as much info in this as possible!

Hey everyone. I am building an iOS app. I am self taught and having trouble with git. To my understanding I should be able to use git as kind of a save point. Once I get to a place I like with my code, I should git add and git commit. That is a save point. If I start coding again and don’t like the saves I have made I should be able to git reset —hard HEAD.

Well what is happening when I do that is all of the files in Xcode turn red and it bricks my app. What am I doing wrong? I have bricked my app twice so right now I am making a backup every time I get to a place I like and am abandoning hit all together.

Thanks for your help ❤️

I'm working on a website and its basically finished, and for context its a Beam.NG mods sharing website, where staff members upload mods, users download.

Everything is working perfect aside from 1 thing, when I use the staff upload mods form, to upload to firehost which then hosts my files, and then what SHOULD happen is, user goes to home page, clicks "View details" on the mod, and then clicks download and it downloads. BUT what actually happens is firehost instead of having the .zip file for the mod, has some odd file called "modsfile" with no extension.
Not sure what I can do, any ideas?

I'm trying to simulate a tesla valve using the lattice-boltzmann method, starting from this code. The problem is that the mask, the boundaries or the bounce-back are not being applied correctly. If I reverse the condition for the creation of the obstacle mask the flow seems to be running more on the inside of the valve.

I don't really understand all the math so I don't know what to try. I tried asking chatgpt but it just tells me to ensure that the mask is applied correctly, the boundary conditions are not applied correctly but it doesn't know how to fix them, and to check the initial conditions.

Hello , so I am currently a 3rd year student in college and I want to know how many hours to spent on coding along with my college studies
