    Taking extremely detailed notes while learning has been a game changer for me. learn programming

    Taking extremely detailed notes while learning has been a game changer for me.

    Posted: 27 Dec 2021 08:05 PM PST

    For the past couple of months, I've developed a habit of writing very detailed notes of just about everything I've learnt. I type my notes in Google docs and include example code snippets too. It might sound simple, but I can't emphasize enough how much this has helped me. I no longer have to worry that I'll forget a concept I've learnt. In fact, the mere act of writing notes in my own words significantly reinforces my learning, and I rarely forget anything I've learnt anymore. Even if I do, I can easily recall just with a quick glance at my notes.

    The language I use in my notes is very precise and specifically tailored to the way I best understand. Basically, whenever I jot down notes, I imagine I'm writing for my "future self" who has forgotten everything and I need to write in a way to make my future self understand. For me, this involves very detailed language and plenty of example code snippets. I try to make my notes detailed enough that I can recall all the concepts I've learnt from my notes alone, without needing to go digging on the internet. Only you know the best way you learn, and your notes should reflect that.

    Whenever I follow a course on FreeCodeCamp or Hyperskill, I jot down notes for every topic I come across in my own words. I do concede that this is a very slow process, but it's totally worth it in my opinion. Through detailed note taking, I always retain everything I've learnt and have reference material tailored for me in case I need it.

    Here's an example of my notes in case anyone's curious.

    Just sharing my experience in case it helps someone. Cheers!

    Would a company hire a pure beginner who is 30+ years old ?

    Posted: 27 Dec 2021 01:50 PM PST

    I'm not as young as I used to be. If a company is planning on hiring a junior, I assume they would prefer picking someone out of university or school. No diploma could really hurt ? Has anyone experience this ? Are we better off working as freelancers ?

    How do you get to a point where you can take on any programming project on not be completely lost

    Posted: 27 Dec 2021 04:32 PM PST

    Hello, I am an intermediate python developper I have worked on some projects like discord bots and web scrapers, but sometimes I still think about cool projects ideas but have absolutely no idea how to start that project how can I get to a point where when I have an idea at least I know where I can start ?

    What's the best course/s on Udemy to get a job?

    Posted: 27 Dec 2021 05:16 PM PST

    I was holding off on doing any course on there, and I was supper impressed by The Odin Project. But I still felt stuck and I didn't feel that Ruby was a relevant back end language.

    I know it's a brilliant clever language, but not many seem to want it.

    TBH I was pirating a lot of course, and then I just bought a course Udemy, and it was brilliant, it was the Colt Steele web dev course, it's since being updated but I really like the old. I'm sure I just prefer what I'm used to.

    But the thing is some people don't want the MERN stack.

    So what do you think are the best course/courses to do to get a job?

    And if you have enough original projects in your portfolio is that enough to get a job?

    Without a CS degree.

    I think I can get a degree they only thing that might hold me back is communications modules, public speaking.

    I totally get why you need to have good "communication" skill, manners basically, being humble, having humility, being coachable on the job, taking direction, giving direction perhaps when it's necessary(as junior staffer).

    But public speaking and doing stuff like that could hold me back, unfortunately.

    Being a butter-fingers on the keyboard and staring the screen looking for my mistake is killing my desire to be a programmer. Sometimes it actually makes me angry.

    Posted: 28 Dec 2021 02:27 AM PST

    Went writing code, I almost never get anything correct on the first attempt. Sometimes my idea is correct, but there is always a small typing somewhere that just throws everything off. Every. Single. Time.

    I was working on a Code Academy project and when I finished, of course there were errors. Ok let me look around for what's wrong. I stared at 30 lines of code for probably 15 minutes. Straining my eyes and getting slightly more irritated each time I couldn't find it.

    I decided to check the correct answer, literally identical. I went threw character by character looking for any discrepancy. I didn't find anything different. At this point I was actually getting upset and saying "wtf" out loud to myself. About an hour had passed and it was about 4 AM now. I had planned to stop completely at 3AM and just go to bed, but this was making me too angry to sleep.

    I opened up another code editor and copy and pasted my code, and the correct code and they both got the same results, but on code academy, it said my code was still wrong.

    After another 30 minutes of wondering wtf did I do wrong I just deleted everything, refreshed the page and tried it again and it worked... I went through again and it was the same exact code. I couldn't find anything different but there must've been something wrong. I finally went to bed at 5AM and was basically sweating from being so pissed off that it took me nearly 4 hours to write 30 lines of code correctly.

    I was on a role with coding everyday for an hour or two for about a month. But after making the same mistakes and spending hours looking for them, it just got too frustrating. This was about 3 months ago and I haven't done anything with coding since then. I played some typing games and practices the past month so hopefully when I jump back in, it won't be nearly as frustrating.

    Is there something similar to theodinproject but for data science, python + SQL

    Posted: 28 Dec 2021 12:17 AM PST

    What should I do next?

    Posted: 28 Dec 2021 02:05 AM PST

    Proud to say that I just finished CS50's introduction to computer science. I've learnt tons of new stuff, and can recommend the course to whoever needs to get familiarized with the basics of cs. I followed passively, as my focus was rather on understanding everything and learning new concepts instead of implementing it by myself.

    Now that it's time to start implementing, what do you suggest me to do next? I'd like to become a full stack developer, maybe one day I might even try the world of blockchain technologies. As a start I'd like to learn some solid language that gives me the opportunity to create a portfolio with some real use case projects. That way I might get my foot in the door somewhere relatively soon.

    Enter C and Python. I would never have considered learning C before taking CS50, but as it's the mother of languages it does seem to make sense to me. Also because once I had a basic understanding of C everything else suddenly seemed so easy. But I'm hesitating if I should start with it as I'm unsure what portfolio projects I could make with it that make some sense.

    And that's where I start to doubt if I should start with Python, which is definitely easier to grasp and quicker to make real-world projects. I already bought a course on Udemy from Ardit Sulce (The Python mega course 2022: Build 10 real-world programs).

    But I have more doubts. As I'm learning to use command line arguments, does it make sense to install Linux (or install a virtual machine running it) instead of Windows? Is Linux easy to use even if you are not familiar with it?

    I'd be interested as well in a course on algorithms and applied maths, preferably a quick and compact one. As maths are not my main focus I'd like just to learn some stuff that might turn in handy when programming. Someone knows a course like this worth taking?

    Furthermore I'd like to use Github, as I understood it is almost a strict requirement to land a job nowadays. Any take on that? Are there other things like Github which you can't go around?

    To summarize:

    1. C or Python, which one to learn first?
    2. Should I start using Linux? Do I have to learn it or will I understand it instinctively?
    3. What (basic) course of applied maths and algorithms would you advise me?
    4. Where to learn Github?
    5. Any other inavoidable resources to learn (like Github)?

    Thank you for taking the time to read and answer to my questions!

    How to Show Experience with Closed Source Projects?

    Posted: 28 Dec 2021 01:59 AM PST

    I am a CS graduate but currently don't have an active public GitHub profile, that's because most of the projects I work on are required (By the Client Himself) to be proprietary, so I am just creating private repos for those projects.

    The problem is, if I want to apply to jobs, employers will check my profile and find it empty, but in reality I have worked on a dozen of projects. How would I prove that in my CV?

    Is Colt Steele's "The Web Developer Bootcamp 2022 worth it?

    Posted: 27 Dec 2021 01:59 PM PST

    I want to get into the world of web development, and I was researching some courses and here are my options:

    1. Colt Steele's
    2. The Odin Project

    The problem is that The Odin Project requires Linux, and I don't really want to install it. I also searched and another option for it was git bash, but I'm not sure if using Git Bash would give me problems when I'm further into the curriculum. (I'm thinking on doing the JavaScript path).

    ​

    Colt Steele's course seems like a good course but I'm not sure because I've read comments on different posts that videos courses aren't that good because in the end one would be just copying what the instructor is doing.

    ​

    Please help me out.

    Where could I get SQL real exercises to learn/solidify what i learn?

    Posted: 27 Dec 2021 05:31 PM PST

    I really want to get another job and i noticed in my area (while not programmer) there are a lot of jobs requiring SQL. I'm checking Udemy for some good rated course, but I feel it would be nice to go beyond to make sure I learned the stuff.

    Do I need to learn linear algebra as a student if I want to work as a programmer?

    I'm a first year STEM (not CS) student. Just wanted to know if linear algebra is essential/necessary to take to learn CS fundamentals and/or land me a good career (in the sense that if I were to get a job, I wouldn't be behind my colleagues who did take it)?

    I want to learn more Java from you guys and also share some experience on taking the Java

    Posted: 28 Dec 2021 01:34 AM PST

    I'm a 2nd year college student from the Philippines. Currently learning Java and I really want to focus on Java ( in short I really love Java). In the next 3-5 years, will Java still the one of the best programming language? and do the company will use Java on their projects?

    I'm just worried about Java or should I worry about myself on learning Java?

    Ohh, one thing, I do love knowing how to create applications and designing UI's of it.

    Sorry for a noob question guys, I'm totally a beginner in terms of programming and I want to learn more from the experienced programmers here.

    Thinking of learning front-end web dev.

    Posted: 28 Dec 2021 01:27 AM PST

    I'm thinking of learning front-end web development. So I can land a job in 3 to 6 months. I'm looking for study materials and are these books sufficient for only front end -

    Learning PHP, MySQL & JavaScript with jQuery, CSS & HTML5 Paperback – 1 January 2015 by Robin Nixon (4th edition because 5th edition is crazy expensive in India)

    and

    Mastering Html, CSS & Javascript Web Publishing Paperback – 15 July 2016 by Laura Lemay (Author), Rafe Colburn (Author), Jennifer Kyrnin (Author)

    Other books are very expensive here so I'm looking at these two books only and I will take the udemy course by Angela Yu or Colt Steele and following the front-end roadmap from roadmap(dot)sh (not my site).

    What is meaning of depth or breadth in context of graph?

    Posted: 28 Dec 2021 01:19 AM PST

    I was studying graph and we have DFS and BFS in the graph where we traversal is according to depth and breadth respectively. Now for a tree, breadth and depth are clearly defined but for graph , we can rotate image of graph(i.e change or perspective) depth changes. Offcourse this is all theoritical(the way I am thinking) but still the question came to my mind how will we define depth and breadth for a graph.

    a---------b--------f

    | |

    | |

    c---------d

    e

    Above is a simple ascii graph(since I cannot post images here), if we start depth first traversal from a, we get to c, but what if we rotate our graph to look like this

    a-----c----d----e

    | |

    | |

    b----------+

    f

    b is in depth now. So what to take as depth and breadth? Or I am just assuming things the wrong way?

    ​

    EDIT : That b is connected to d in second graph too, idk why it is not appearing in output.

    Rotating k times a linked list of size "n" with complexity O( (n-k)%n )

    Posted: 28 Dec 2021 01:12 AM PST

    Hello everyone!

    For an exercise, I have to rotate a linked list k times with a computational complexity O( (n-k)%n ). I even have the solutions (that is here in the rotaten function), but I'm struggling to understand the meaning of the procedure. Why Do I have to do it in an (n-k)%n complexity? What's the meaning of this calculation?

    Hash Tables stored?

    Posted: 28 Dec 2021 12:55 AM PST

    Hi all,

    On my journey to learning data, structures, uses etc...

    Been mostly using excel and access, while learning python and it's uses for those programs. Pandas, OpenpyXL etc....

    Stumbled upon ways to structure data, specifically Hash Tables. In my efforts to learn more, all I can really find is people on YouTube creating code for how to make them.

    What all the videos fail to miss is how the heck they're stored once created?

    They can't just store data in a line of code, it has to push/pull from an underlying program?

    My best guess is.... I have a data set that will be looked up. I assign those deidentified hashes. I have a database... I assign those buckets.

    I lookup specific item.... It pulls it from the bucket and makes it viewable to be used.

    What am I missing here?

    Current students, what are you learning this winter break?

    Posted: 27 Dec 2021 08:52 PM PST

    Would you please share the current resources and goals for learning programming or other CS-related topics this winter break? All the resources I mentioned will be listed at the bottom! A student (or self-learner! ) can accomplish a lot over a month's break and would like to make the most of it, and maintaining a rhythm of study is key to staying sharp.

    I am currently taking the C++ for programmers course offered free by Udacity to reinforce the topics I covered in my previous class. I also have a copy of Sweigart's Automate the Boring Stuff with Python. I wish to learn Python basics by completing the text. I do not have any front-end experience, so I am also going to dive into The Odin Project to understand JS. Can you recommend any front-end resources? I will also strengthen my math skills on Khan to prepare for Integral Calculus.

    My goals are

    1. Strengthen C++ and CS Theory, and finish "Automate the Boring Stuff with Python"

    2. Learn enough front end to launch a basic portfolio website.

    3. Strengthen math skills.

    RESOURCES

    1. https://www.udacity.com/course/c-for-programmers--ud210. Free C++ Course
    2. https://inventwithpython.com/Free PDFs of Sweigart's text.
    3. https://www.khanacademy.org/For math, they also offer a College Computer Science Principles course, which is worth visiting IMO.
    4. https://www.theodinproject.com/Praised resource for learning Javascript and programming fundamentals
    5. https://hyperskill.org/ Offers many interactive courses for different languages, allowing you to choose a path. They offer a free trial that you can lengthen by completing course challenges.

    Where can you show off your projects?

    Posted: 27 Dec 2021 08:36 PM PST

    I was wondering if there is a place where you can show off your different projects like in a website so people can play or interact with what you made? I know github is there to show off the coding for a project but I want people to actually use the projects created. Any help given is appreciated!

    Is it possible to be proficient at multiple programming languages?

    Posted: 27 Dec 2021 08:36 PM PST

    Hi i have learned python and i am comfortable with the basics,planning on learn html,css,js and then jump to java for android app developement just so i have multiple choices to choose from to see what i like the most.Can you be really good at lets say 5 programming languages and is it doable to learn them quickly and what are your thoughts on this,should someone master one language first then go to another or if you comfortable with the basics and syntax of the language you can jump to another language?
