| Is it normal to be regularly checking back on previous projects to remember how to do things? Posted: 13 Jun 2021 08:34 AM PDT I've started trying to learn how to code, and while I'm doing pretty well understanding the concepts, I find myself regularly checking back on previous projects to see how to do things. For example, I recently made a checkerboard using Python, html, and CSS where the url input could change the size of the board and colors of spaces. And several times I felt stumped on syntax and have to go back and look at previous ways I implemented similar code and rework it to fit. Is this pretty normal among developers or should I really focus on memorizing code? [link] [comments]  | ||||||||||||||||||||||||
| Posted: 13 Jun 2021 04:00 AM PDT Hello , i am a relatively new programmer but having problems remembering syntax. However, when given the syntax i easily understand the concept and the function behind it. Is this the ideal approach ? should i focus on the concept and function rather then memorizing the syntax ?

| Basic CS for a full-stack developer without any math background. Posted: 13 Jun 2021 05:18 AM PDT Hello all, I hope you are doing great! I started my journey as a developer, and I want to take a 6 month learning "vacation" to improve my developing skills and learn only the CS concepts that are necessary to write a solid application. My goal is simple - I want to be able to write a software, a product, just like a "startup". So my question is - what are the core CS fundamentals that are going help me to create a better product? I have no math background, but I am fine with learning the basic and advanced from there. I want to focus learning what is basically the most important stuff, the stuff that actually being used every day and make a change. Thanks, folks! [link] [comments]  | ||||||||||||||||||||||||

[Hint] o To weigh the five cubes only up to two times to determine which one weighs more, you will need to weigh for the 1st round four cubes by twos and leave one cube aside. o If the two parts of weighed cubes are equal, then the cube we need to determine is the fifth cube – the one we set aside. o If not, then one of the four cubes we weighed is the one we need. To do this, we will disregard the pair that weighs lesser and focus on the pair that weighs more. We will weigh that pair for our 2nd round, and the cube that weighs more than the other is the cube that we need. [link] [comments]  | ||||||||||||||||||||||||
| How might you go about coding a random world map generator? Posted: 13 Jun 2021 11:08 AM PDT I would like to make a basic 2D map generator, like a fantasy map. Something that will essentially create random noise and then maybe randomly assign points of interest (that I can refine later) like cities and such on land tiles. My first thought was that I'll need to make a grid of points, assigns weights, and use marching squares and then separate the shapes as land/water/etc. However, I've only used Perlin noise for marching squares and in my experience it tends to end up in weird looking archipelagos or just a single continent depending on the allowance. Is there a better noise function I could use or is there a more optimal way I should try first? [link] [comments]  | ||||||||||||||||||||||||
| Do online code-compilers use my internet to download packages? Posted: 13 Jun 2021 06:53 AM PDT I apologize if this sounds like a stupid question. I come from a place with very bad internet connection but I have to work on a project which requires tensorflow or pytorch both of which I know has very large size with respect to what my internet can handle. So if I use something like repl.it and import the packages there, will they still use my internet to download the packages? [link] [comments]  | ||||||||||||||||||||||||
| [Ruby] What is the convention for returns in Ruby? Posted: 13 Jun 2021 11:31 AM PDT I come from Java and Python, it's second nature to use what's the convention for this sort of thing? It honestly feels sort of silly to just omit the word [link] [comments]  | ||||||||||||||||||||||||
| Feasibility of a credit card/bank account dashboard? Posted: 13 Jun 2021 11:05 AM PDT I would like to build a platform that displays all of my credit cards and their balances (I think the app Mint pretty much does this?) in one platform and offers the option to pay these balances off. It seems like it would be challenging/filled with red tape to go through the process of having access to the account details to so many different vendors? I'd also like to create my own "credit card" I could submit purchases through to act as middleware before going through one of my cards like it normally would. Having never worked with purchasing or how credit cards work behind the scenes I have no idea how challenging this could be as an individual. Anyone's thoughts would be appreciated! The stack I was going to go with would probably be the MEAN stack unless there is something that a specific language would help me accomplish towards my goal with this credit card platform. Edit: this platform would really just be for me to test out an idea I have and if it worked out at all I do think others would find it useful. [link] [comments]  | ||||||||||||||||||||||||
| Unable to get CORS to work with a Vue.js app and a socket.io server Posted: 13 Jun 2021 08:51 AM PDT I have a Vue.js front end app on a S3 bucket and am trying to get it to connect to my backend socket.io server. My front end runs on "dash.mydomain.com" and my socket.io server runs on "socket.mydomain.com" I am hoping someone can take a look at the below and help me figure out why the front end is giving me the error message below. It all seems to match up to me. Do note that I have tried "socket.mydomain.com" as "VUE_APP_FE_URL" before with no luck there and it giving me the same error message Current code snippet In my .env file Error message Backend app.js env from container [link] [comments]  | ||||||||||||||||||||||||
| Help! I have no idea what to do after my bachelor's in computer science engg. Posted: 13 Jun 2021 08:43 AM PDT So for starters, I am a month away from graduating and I have no idea what I've done these four years. I have no idea how to program and to be fair, I really don't think programming is my cup of tea. Is there any other field I can experiment that comes under computer science but is not necessarily too technical? Idk if I'm making any sense. Any advice would help.

| Is there a framework that lets you run line by line in Assembly showing you important data? Posted: 13 Jun 2021 10:08 AM PDT Hey there. I remember I saw a glimpse of a framework like that a few days ago. The guy was coding in assembly and had some boxes that showed the state of flags and other things. I might be wrong though. I tried looking online but found nothing. Any help? [link] [comments]  | ||||||||||||||||||||||||

| Should linked list be avoided unless absolutely necessary? Posted: 13 Jun 2021 08:52 AM PDT The stuff I've been reading on them lately states that utilizing linked list often times isn't a great idea. If this is true... why? [link] [comments]  | ||||||||||||||||||||||||
| python error about a column that exists! Posted: 13 Jun 2021 11:52 AM PDT so I'm new to python and ML. i wanted to indicate a prediction target from my dataframe. the target is the "price" column in the data frame(which exists!!) but I get so many errors from for example 8764 line which doesn't exist! and the last line of error is KeyError: 'price' plz help sigh~ BTW i have done .dropna(axis=0) for my dataframe too [link] [comments]  | ||||||||||||||||||||||||
| [Asking Advice] [Beginner] Creating a Simple Inventory System Posted: 13 Jun 2021 11:39 AM PDT I know there are paid and possibly even free solutions, but I thought that perhaps I could start this as a learner project. Preferably a project that takes a more similar process to that of real software development. Starting with defining the project scope, UML diagrams, ... Not that I am actually knowledgeable in this matter. I know little to nothing. I hope someone can put me in the right direction. Just brief (chronological) instructions that I could use to look more into would be greatly appreciated. Anything more is absolutely welcome!
No adequate system is in use for managing stock in the vehicle. A simple digital inventory system could alleviate some issues. No fancy pansy software. Don't need a whole ERP system. There are no orders, sales, suppliers or analytics.

| Posted: 13 Jun 2021 11:36 AM PDT How do you know if you are good with Javascript to move onto building react apps. I've been studying html, CSS and JS for a month now but I can't start a project from scratch. Does that mean I don't know as much as I think or is it normal to just go on youtube and Google to search up how to add features you want? It's abit of a dilemma [link] [comments]  | ||||||||||||||||||||||||
| Writing an Algorithm - help needed [urgent] Posted: 13 Jun 2021 11:22 AM PDT Hello! I am working on a problem that is asking me to write an algorithm with the following specifics. There is a combination locking mechanism that has four wheels, each marked with 5 digits (0…4), as shown here https://imgur.com/a/LToAHS2 We are given the current 4-digit combination on the lock (which is not correct), the desired combination (is correct), and a list of n forbidden combinations. We have to create an algorithm with these inputs that outputs the count of the fewest steps required to rotate the wheels to get the correct combination without ever landing on a forbidden combination. We also have to use general variables for the given inputs. For example, the number of wheels could be w, the number of consecutive digits on the wheels, d and so on. Knowing the running time would also be nice. Here's an example if the above was a bit confusing. Example: Starting combination 0424, desired combination 1410, forbidden combinations: 1420, 4300, 1242. Required turns = 3. The turns would be wheel 1 left to 1424, wheel 3 right to 1414, wheel 4 left to 1410. Note: You could NOT move from 0424 to 1424 to 1420 to 1410 because you would have to stop at 1420 which is a forbidden combination. I'm not exactly sure if this is needed, but we've been learning about graphs (adjacency matrix / list), BFS and DFS if any of those help. If anyone has any guidance for how to begin or more that would be incredible :D [link] [comments]  | ||||||||||||||||||||||||
| solving top 20 ( top k ) sold items in the past hour in python3 Posted: 13 Jun 2021 11:07 AM PDT I am trying to solve a problem in python to get the top items sold within the past hour. The time range can be variable ( Eg: get top sold items in the last 3 hours etc ). My dictionary looks something like this:
I can also add an entry to the dictionary when an item is sold , say curr_timestamp = timestamp32 and we sold item_id_3 at this timestamp, dic now becomes
What is the most efficient way of getting the top items sold by count in the last hour ? My current plan is to maintain a heap but I need to re heapify each time a new item is added and then check if each timestamp is within the last hour for each item - which is very inefficient. I was wondering if there is cleaner way to solve this [link] [comments]  | ||||||||||||||||||||||||
| Binary numbers and common operations illustrated and animated Posted: 13 Jun 2021 11:07 AM PDT I wrote an intro to binary numbers with lots of visualizations and animations a few months back and thought it may be helpful to anyone getting started with programming or looking for a deeper understanding of binary numbers (all code samples are in Python): https://csanim.com/tutorials/intro-binary-numbers-bitwise-operations-ultimate-visual-guide [link] [comments]  | ||||||||||||||||||||||||
| Online Courses With Scheduled Class Meeting Times Posted: 13 Jun 2021 11:03 AM PDT I think when it comes to learning anything or picking up a skill, consistency is key. The problem that I have with learning to program is finding a consistent schedule to actually sit down and learn. Do any of you know if there is a thread for courses with scheduled class meeting times? (Something akin to an online classroom.) Hopefully one in which i could collaborate with other students. I've taken a look at college courses but in my experience I've found it difficult to gain any real world / real scenario programming skills, regardless of what my grades say I know. I'm aiming to learn python but any info would be greatly appreciated [link] [comments]  | ||||||||||||||||||||||||
