    Learn to Code With Data Visualizations - Interactive Python Lessons - Then Keep Going :)

    Posted: 30 Aug 2020 06:11 PM PDT

    Hey Gang,

    I've been teaching people to code for the past five years, and wrote some lessons so that people with no knowledge could get ramped up, and see the purpose of coding. I battled tested the first fourteen on my mom to make sure :)

    I'm providing 70 free interactive lessons that cover: intro to programming, pandas, intro to ml, and building a neural network from scratch. No login, just start.

    All of the 70 lessons are here, and I'll be hosting free virtual workshops on each of the subjects over the next five weeks.

    I'd love to know what you think!

    1. Introduction
    2. Variables
    3. Lists
    4. Dictionaries
    5. Coding Tips
    6. Loops
    7. Nested Data
    8. Make it Easy
    9. Loop Over Data
    10. Loops to Lists
    11. Live Data
    12. Functions
    13. Arguments
    14. Code to Codebase

    I feel like I'll never get there and that I'm slowly progressing. There's a sea of information out there and no matter how much I learn, I always feel inadequate. (Self-taught)

    Posted: 30 Aug 2020 01:03 PM PDT

    Today I learned about the concept of Object-Oriented Programming (OOP) vs structural programming for the first time.

    It feels like I should have learned/heard about this earlier when I first started learning (2 years ago now) and now I feel like I'm missing a lot more. It made me question whether or not I'm actually learning what Iactually need to be learning. How can I assess my progress when there's no one else to do it for me. I miss going to school only because school played the role of an assessor. There's always a scale where I can put myself on to assess my progress/my abilities.

    I always consider myself a beginner. This feeling of inadequacy kinda hurts and is kind of dragging me down and I'm always hesitant to participate in conversations with professional coders.

    I know about the imposter syndrome, but it's not just that. Any thoughts/tips?

    How do I read documentation?

    Posted: 30 Aug 2020 10:29 PM PDT

    I know this sounds like a silly question. But I'm sick of YouTube tutorials and various other tutorials I just want to get into the heart of it. I have a pretty good foundation of programming, Python and C++. So I know how to write code and create objects and classes. I have a pretty good understanding of object oriented programming.

    But when it comes time to learning third-party library's or frameworks i'll take a look at the documentation and none of it seems to make sense. It seems like documentation has its own syntax. Are there any tricks to learning documentation or just just keep reading and reading it? I want to just cut out all the bullshit and go straight to the docs.

    I feel like at this point in my learning trajectory I should have a pretty good understanding of documentation. But I don't which is kind of embarrassing. So any tips would be much appreciated. Thank you.

    A recommendation on how to learn C++

    Posted: 30 Aug 2020 06:00 PM PDT

    Hi everyone, I am a Computer Engineering student and I have some issues learning C++. To start off, I took the introduction class 3 times. First two I dropped out because I did not like the professor and the third time, I passed with a B-. I then took Discrete Math and Data Structures, both of which I got a B in. I took Data Structures last semester which is when COVID hit. At that time, I was pretty depressed and kept screwing up Data Structures. I feel really useless when it comes to coding. Now, I am taking Algorithms and I am afraid I won't pass because I don't really have a good professor. I understand the idea when it comes to a problem but I suck at implementing it. Can anyone recommend me resources and things that I can do to get out of my situation?

    Is 'Cracking the Coding Interview' book particularly useful for someone who codes in Python always?

    Posted: 30 Aug 2020 12:06 PM PDT

    I have heard a lot about it and it seems to be in C++(Edit: It's in Java). Was wondering if it was worthy of purchasing it for someone who codes mostly in Python.

    Thanks for those who respond.

    Want to Join a Discord Group for Noobs?

    Posted: 30 Aug 2020 06:40 PM PDT

    Hey all,

    Just started my coding journey. I'm struggling not being able to bounce ideas / questions off other learners in a similar position. So I was thinking of starting a Discord group that could just kind of be a place for technical questions / words of encouragement? Anyone keen?

    I just started Harvard's CS50. So if you're working on that, then we'd be studying the same material. If not, we could still share resources and potentially form a bit of a network / community.

    Let me know if this sounds interesting and I'll start one up and send invite links!

    Cheers

    I have learned the basics of Data Structures, what should I learn next?

    Posted: 31 Aug 2020 12:06 AM PDT

    So, I've been learning Data Structures from the past three months on YouTube, and today I completed learning Graphs, DFS, BFS. I'm from EC background and I've never encountered Data Structures in college. Also, I'm a slow learner so I spent a lot of time learning these.

    I also remember the time posting here about how to learn Data Structures. I literally spent one-month understanding how a linked list works and how pointers are used to rearrange them. Now, I want to learn other stuff and I don't know what to learn. Could you guys please guide me in the right direction?

    I just want to get a placement or a job in software engineering. Any help would be appreciated.

    Thanks in advance

    What is the best book for modern C++?

    Posted: 30 Aug 2020 11:34 PM PDT

    I have read C++ crash course and it was amazing. However it didn't cover the modern C++ . It covered the basics. I am looking for a book that covers modern C++ uPto the C++ 20 standard.

    I don't know if I should read the a full book or try to find shorter tutorials.

    I do get a lot of practice because I have several years of C++ experience and my full-time job is in C++. However I have heard that fintech requires very very expert level c++ which I may not have.

    I tried reading effective modern C++ but it wasn't so good beyond the second chapter.

    My ultimate goal is to get a job in fintech which requires some really good C++ knowledge. I would say my above knowledge is just average.

    Best resource to learn web development as an experienced backend dev?

    Posted: 30 Aug 2020 08:57 PM PDT

    I didn't come from a CS background, and worked my way up from a junior data engineer to a software engineer at a major tech company working on distributed data systems. I've had web development as a personal goal for a while, but since it isn't at all applicable to my day to day I always find other learning to prioritize.

    When I have started, I get discouraged because the tutorials are so basic and that makes it hard to remember all the little intricacies of HTML and CSS. Any recommendations for a good course that will take me from beginner to being able to build a decent looking website?

    Learning Advance SQL/ SQL Queries

    Posted: 30 Aug 2020 07:55 PM PDT

    Hello everyone, I have a job that mostly requires SQL, doing SRSS reports, writing long queries/editing packages. My manager told me to take an advance SQL course, trying to google courses but all I get is udemy courses. What I am looking for is a course that covers basics then moves onto how to write queries efficiently and the complicated query subjects whatever that may entail. I already have a background in Java, python and front end languages but I freeze up sometimes when it comes to writing/editing SQL packages. Does anyone know or have any recommendations on what I should look into? Purchasing a course isn't an issue my company reimburses me on these kinds of things.

    How to implement MVC on background tasks in python?

    Posted: 31 Aug 2020 12:19 AM PDT

    I am making a desktop download manager with Python (to learn). Think transmission (torrent client). I already made a rushed working version in which the UI elements also held the application code. However, I wanted to write better looking code so I started trying to separate the UI from the app logic, allowing me to change the ui at any time, or even use a command line interface instead. However, I am facing problems at conceiving the way in which the downloads will update the UI.

    As a download manager, it should be able to run some download tasks, each in their own thread (so as to not freeze the ui). Each download task will have a certain progress (you can think of it as a percentage). How can I keep the UI updated with every bit of the download that gets done? One option would be to set the controller to query the progress of every task every second or so, but I don't feel like it would be ideal. So what other alternatives are there?

    Maybe I'm just not cut out to be a coder

    Posted: 30 Aug 2020 03:31 PM PDT

    I graduated from a part-time full stack bootcamp recently. I'm currently in customer support so this is a career change for me. In my job search I've received two coding assessments so far. Both I was unable to complete during the time frame given and I found to be incredibly challenging. Both were very similar in nature. Get data from an API, iteration of the data and a comparator based on dates. I'm finding the iteration of data to be where I hit a wall on both. I'm feeling incredibly discouraged. I know I could be a great coder if some company took a chance on me and mentored me. But after failing miserably at these coding assessments I feel like maybe I'm just not cut out to be a coder.

    Am I doing this right? looking for words in a set (python)

    Posted: 31 Aug 2020 12:09 AM PDT

    I'm looking to find if there are any words from the set WORDS in a string.

    This is what I have so far:

    if any (c in WORDS for c in pw): # TODO: -1 if any word in WORDS appears in pw score -= 1 

    It is part of a function I'm using to rate password strengths on a point-based system.
    I have the variable WORDS defined as a set and I want to check if the pw string contains any of the words in the set WORDS. If there is at least one in there it should -1 from the score.

    I can't figure out if I'm doing this right. I hope someone here would be able to let me know. Thanks!

    I had another (finally!) breakthrough, and I owe it to you guys and a tip with tutorials I'd like to share!

    Posted: 30 Aug 2020 08:10 PM PDT

    Hi Everyone,

    I'd been struggling with learning structs the last month. My time lately has been accounted for by work, my relationship to my partner, friends and trying to take care of my own mental health. This means that there might be times when I need to be away from my laptop and learning to code. Needless to say my progress in learning to code has been a bit slower than I would have liked, especially after doing it for about five months now. Although in my defence, I'm also self taught with online tutorials, and help from some of you fine and lovely so-and-so's.

    My breakthrough came from something I decided to do with the Angela Yu iOS BootCamp series, when I became rather frustrated with Structs. For whatever reason they just weren't sinking in. I knew what they were for, but really had trouble putting them into practice.

    What I decided to do was to mirror a new app idea to the tutorial lesson, and work with what I already knew. So it was going to be pretty basic to start, but by breaking it all down to specific core components, it finally started to make sense. I worked through a system that made the most sense to me: Autolayout, connect IB objects, and then create the different files. The big thing I was hoping for was moving data. Moving data between the different files as Model/View/Controller was actually a pretty big deal for me personally. It worked. I felt great!

    Anyway, I know my writing tonight is a bit sloppy on here.

    My tip is that whenever you're done a tutorial lesson, say structs or classes, try to create your own version of that app or lesson. Use your own idea but mirror the lesson. What I did was keep my finished copy of the Angela Yu series open and work from that. It really helped me to solidify my understanding of what I'd learned.

    Hope you all have a great night!

    Help !! Java Apache Poi API

    Posted: 30 Aug 2020 11:55 PM PDT

    I need help regarding docx file processing using Apache poi api.

    Use case of project module.

    1. I am parsing the Source Docx file to my java code. This docx file has a Mangal font ( Unicode font) text.

    2. I am treating this docx text as a string input to uniToShree function. Again this function returning string as an output.

    3. This output is a translated text from Unicode to Shree lipi.

    4. Now, this output is set by the java code in the target document. This is the final document where I got the translated text.

    So till now what I was doing is, 1. Before XWPFrun it was working fine. I was getting the output but without formatting 2. After writing the XWPFrun code I am getting Null pointer exception error and StringIndexOutOfBoundsException when I am passing docx text as an input to the uniToShree function

    [Discussion] Integrating 3rd party APIs into a backend project

    Posted: 30 Aug 2020 11:51 PM PDT

    Hi guys, hope y'all doing well.

    I'm trying to integrate Stripe's Payment API into my backend project but I'm facing a difficulty in terms of which layer it should go in. So far I've realized it should be in the repository (correct me if I'm wrong) cause it's related on how data is stored and managed and the job of the repository is to hide how data is handled. Now the questions are:

    1. Should the repository depend on abstractions rather than direct access to ORM and 3rd APIs such as Stripe?

    2. If so, should these abstractions use Domain or Data model to communicate with the repository?

    3. What's the best way to handle atomic operations when using multiple data sources in this case(the database and the API since one depends on each other) ?

    I searched a lot but couldn't find an answer for any of these questions, I would appreciate if anyone could guide me on how to implement it properly. Thanks
