    For people who live in the Bay Area - I'd like to teach you programming for free

    Posted: 29 Jun 2018 10:17 PM PDT

    Who am I?

    I recently graduated with a Master's in Computer Science where I mainly focused on Machine Learning. I was given the award for best teaching assistant of the year. I also taught several weekend workshops when I was in college, with the largest one being attended by about 100 students (from freshmen to seniors). I've been working as a software developer for a year, but I've been programming probably since I was 10. I've been told I'm good at teaching and I like doing it.

    Is it really free?

    Yes. I'm using this post to gauge interest. I will hunt for a suitable location (probably in East Bay) depending on how many people are interested. If you have suggestions for what kind of location would be best suited for this please let me know. All you have to do is bring your laptop and get yourself to the location. Literally the only thing you will pay for is your travel costs. There are no hidden costs, I'm not promoting my Twitter or my Patreon or my Twitch or anything at all.

    What's the plan?

    Ideally, I'm hoping you've taken at least one CS course in your life. I would want to start past the basics such as conditionals and loops, but wouldn't mind teaching these if required. Either way, I'm hoping to push people in to the deep end pretty early on.

    I'm planning a curriculum but the intention is to teach students to create a web app (React + Python, probably). I don't know how long the course will last, but I was thinking of weekly classes lasting a few months. Again, I'm waiting to see how people respond.

    If you have any questions I'm happy to answer them.

    GitCheats CLI: Print Cheats Into Your Terminal

    Posted: 29 Jun 2018 05:35 PM PDT

    Hello,

    A few months ago I have shared my project GitCheats where you can filter out git commands easily while you are trying to get used to Git CLI. Today, for reasons unknown, most likely for boredom, I created another project where you can get those cheats directly into your terminal, as a companion app for GitCheats. For instance, gitcheats commit from terminal returns the description and related options to that command into your terminal. If you are interested, here is the repository link with description about how to install it: Git Cheats Cli

    GitCheats website now supports different languages, and I am planning to add that feature into terminal app as well, with language arguments you will be able to fetch descriptions in supported languages.

    I hope someone finds it useful!

    Should I learn linear algebra? Why or why not?

    Posted: 29 Jun 2018 03:11 AM PDT

    I'm a beginner who still can't tell between modules and classes.

    Should a programmer learn linear algebra?

    Looking for an up-to-date and comprehensive Django (Python) tutorial?

    Posted: 29 Jun 2018 12:52 PM PDT

    I'm looking to get to grips with Django development, but as somebody who likes to understand how things work I've found most tutorials skip over the inner workings so that I'm not really sure what the next steps are once I've finished the tutorial.

    Can anyone share a link to a comprehensive tutorial that will emphasise the key workings of the framework? Preferably something recent or updated - thanks!

    What can you develop using Python?

    Posted: 29 Jun 2018 05:54 PM PDT

    Hey, I wanted to know what are some other programs I can develop using Python? I've already made a few games like the snake game but I wanted to make something bigger. I want to make something that may require a few days or weeks to make but can be useful. Thanks!

    (Python)Hit "the wall", now looking for help to gain a sense of direction for my first project

    Posted: 29 Jun 2018 08:09 PM PDT

    Hello all!

    For my first project I'd like to make a program that shows me how much time I'm spending on each program on my computer. I want the program to show me how much time I spent on each program that day, week, month, and total all time.

    However, I'm not sure exactly where to start. I know I want this program to have a user interface, but I don't know how to build that. I know I want the program to have graphs that show the data in a more visual manner, but I don't know how to do that. I want to learn, but don't know where to start.

    I have finished the first half of "Python Crash Course: A Hands-On, Project-Based Introduction to Programming" but I stopped when it came to the projects because I'm more interested in creating the program I described above.

    I'm not asking for someone to make the program for me, but I do need help for finding out where exactly to start. I understand the syntax of python. I understood everything from dictionaries, loops, functions, and classes, but I'm at a loss for what I am trying to do.

    Thank you all very much for your help. From what I've seen in the top posts you all are very helpful and kind.

    Where can i learn about Image recognition? What are key steps for a programmer to write a program that solves captchas?

    Posted: 29 Jun 2018 01:10 PM PDT

    Lets say i have a small image of a character or a number.

    And i store that image as a matrix where each element is a string with RGBA or HEX value of each pixel.

    What i do now? How do i tell my program: "Hey this is blank space. And this is a part of a character or a number".

    Lets say i can convert those RGBA/HEX values into just 1 and 0 to be easier.

    How should i aproach this? Im clearly in the dark here so i need some problems that are much easier. What could i solve that will give me an understanding of this consept and bring me closer to writing program that takes .jpg .png images of numbers and letters and coverts them to a string?

    I want to automate Nintendo emulator. Where should I start?

    Posted: 29 Jun 2018 10:48 PM PDT

    I know about TAS, but that thing only press button on perfect frames, but I want to emulate something based on the output on the screen.

    On Harvest Moon GBA there is a higher-lower game. The premise is simple, save state before answering, load if my answer is wrong, and save state again if my answer if right to proceed to next question.

    I know Python, I don't know the method to make it "see" if my answer is right or wrong, do I have to use image processing library and make it "read" the text on the screen? or maybe does the emulator output the message on the screen on stdout somewhere?

    Thank you in advance.

    I code, but I'm an awful typer

    Posted: 29 Jun 2018 07:33 AM PDT

    I'm relatively new to coding (been coding for not much more than a year), but I've always just been awful at typing and never really learned to type properly. It makes me much slower than I need to be and when I step up my speed I tend to make many typos (which is especially frustrating in code).

    I feel like I've been typing wrong for so long, that it's become really hard to change, and that there's so much I want to learn that investing time aside just to improve my typing skills isn't the most practical thing (I also really have very little time on hand nowadays). Is there hope for me? How can I change this stubbornly ingrained flaw of mine? I feel like it is significantly affecting my output and skill as a coder...

    Why is it that my "Remove" function doesn't properly work when I open this project up in the browser (does not matter if Chrome or Safari). I still get the blank to-do before I start anything that I need to delete before I start a list. Thanks, guys! Code on :)

    Github repo causing crashes

    Posted: 30 Jun 2018 12:31 AM PDT

    When looking up K&R, I stumbled across a github repo that I think contains a pdf of it. Upon viewing the repo, however, I saw the github loading animation and then my computer slowed down and basically froze and I had to reboot. I tried opening it up on my phone and this time it just crashed the chrome app.

    I am more curious than anything else as to why this is happening. I could not find anything online related to github website crashes.

    How often do you realistically code/learn each day?

    Posted: 30 Jun 2018 12:21 AM PDT

    I don't really program as much as I should, especially for an undergraduate student in summer. I was curious how often you guys realistically program, read, and learn about programming on a daily or weekly basis? It will give me a good idea of what I should be at least doing to keep up with others. I program maybe an hour twice a week and look up generalized topics about languages and computer science maybe 2-3 hours a week. How about you?

    Weird Lambda Behavior in Java 8

    Posted: 29 Jun 2018 11:35 PM PDT

    So, I was playing around with Lambda Expressions, because I wanna get better at them.I discovered this when I was messing around: Take the following program.public class Weird{

    enum Properties {

    EXAMPLE;

    }

    public static void Why(List<String> list) {

    int i = 0;

    list.forEach(i++%2==0 ? ((element) -> System.out.println(0)): (element)-> System.out.println(2));

    }

    public static void main(String[] args) {

    ArrayList<String> l = new ArrayList<>();

    l.add("1");

    l.add("1");

    l.add("1");

    l.add("1");

    l.add("1");

    l.add("1");

    l.add("1");

    l.add("1");

    l.add("1");

    Why(l);

    }

    }

    So, you might expect this program to produce the following.
    020202020
    But instead it prints
    000000000
    Why?

    How to get feedback on projects?

    Posted: 29 Jun 2018 11:34 PM PDT

    I just uploaded my first proper project to GitHub: https://github.com/GregLahaye/twitter-helper

    I created it to start to build up a Python portfolio to hopefully get an internship next year (first year of uni).

    As I have never published a finished project before I am interested in getting some feedback on the code or anything missing from the repo.

    Most places like Code Review Stack Exchange and /r/reviewmycode seem to not be very active.

    Thanks.

    Code Review - Python Coin Toss Game

    Posted: 29 Jun 2018 07:14 PM PDT

    Create a coin toss game in python for a class.

    Works fine but I'm sure there could be some improvement that I'm not seeing.

    Any feedback will be appreciated!

    How do remote security cameras work in regards to networking(data transfer without port forwarding)?

    Posted: 29 Jun 2018 10:44 PM PDT

    I have a security camera($20) that allows me to remotely view it from anywhere remotely. It uses a large amount of data, but what kind of architecture would they have in place to allows thousands of users to concurrently stream video (in the case that they can't open ports / use UPnP on the router/accept incoming connection)?

    Would they have to have a server that receives the entire stream, from thousands of users at the same time, and output it to thousands of devices (which doesn't seem feasible, so I'm missing something).

    This also relates to game severs- I just don't understand (if you can't open ports/ allow incoming connections), how you can stream that much data through a 3rd party server (or many of them) for almost no cost.

    Question about debugging

    Posted: 29 Jun 2018 12:51 PM PDT

    I heard that new programmers who get employed usually spend most of their times debugging code. My questions are: what cause the code to get bugged? and how often does this occur? also, can you do this work remotely from home? is it popular freelance work?

    Can you actually become a master at programming? (Here me out)

    Posted: 29 Jun 2018 10:21 PM PDT

    So I just saw a video of a guy that's been in the tech industry for over 10 years and he said that computer science is not like other careers. He stated that even people that put in 10-15 years at the job, they still wont be the best because in 10 years or so an entirely new technology will be out and you'll basically be back at ground 0. I don't know if this is true, but I've been programming for awhile now, and I don't really like the way this dude described it. If I dedicate my life to this I want to be an absolute beast at it in my later years.

    Using voter data from Excel spreadsheet to automatically contact voters

    Posted: 29 Jun 2018 10:06 PM PDT

    Hi, I'm really new to all of this so I'll do my best job of explaining the issue, but please forgive me if something is unclear. I'll be glad to clarify.

    A friend and I are likely to be approved for a grant to build a website for our city to engage voters. We will receive an Excel file with voter data for all of the registered voters in our city. This will include phone numbers for everyone. We're wondering if there's a way to automatically send out text/call alerts with information about upcoming elections, amendments, etc -- similar to the way universities have systems where students can receive automated calls about emergencies.

    What would be the best way to take this data and use it to contact people? It was suggested that I do this with Python, but I'm not sure where to start in the slightest.

    Any guidance would be greatly appreciated!

    Learning C++ but I feel like I can't make any projects with it?

    Posted: 29 Jun 2018 05:28 PM PDT

    Took my first CS class this summer and it was Problem Solving and Programming 1 with C++. This was our syllabus.

    I want to get started with creating projects to build my GitHub and showcase them on my resume for internships next summer. But I can't think of a practical use of C++ in anything. It's a embedded systems language. How am I supposed to code software apps? Do I pick up Java or Python for this? Maybe with C++ I don't have enough knowledge to create a project?

    Edit: If you could give some examples of every day software or apps that we use that are made with C++, that would help in understanding and getting inspiration on what sort of project I can tackle.

    What is the best program you have ever made?

    Posted: 29 Jun 2018 02:55 PM PDT

    I am currently learning to code and just out of curiosity, I just wanted to hear some of the programs that you guys created.

    For example, what is the best thing you have ever made to make either yours or someone else's life easier? Whether it was for work purposes or just to help you in life. How long after you started programming did it take you to create something like this?

    I would just like to hear what you guys have been upto.

    [Python][Code Review] Script to download saved images at reddit

    Posted: 29 Jun 2018 05:51 AM PDT

    TL;DR: I coded a reddit saved downloader that download images from user's saved posts and I am expecting your suggestions: https://github.com/aliparlakci/bulk-downloader-for-reddit

    I was searching for a script that features it and stumbled upon aesptux/download-reddit-saved-images. But it didn't take long until I realised it was outdated and, I will be honest, a little useless because of how it deals with imgur links.

    So for the sake of learning and improving myself in writing code and using Python, I wrote a whole new script that I found more useful.

    But the main thing I am posting this is that I know so little about Python and its built-in methods. (I even learned that there is a built-in string parser while coding this!) Therefore, there might be some lame designed features.

    I encourage you to download it and give it a shot. What do you think that might be done to improve it?

    I seek your suggestions. Here's a link to the repository: https://github.com/aliparlakci/bulk-downloader-for-reddit

    Hello Reddit!

    I'm trying to make a program that ask the user for it's name and then age to calculate years left for retirement. I'm using visual studio and i'm stuck (also a newbeginner). When I type the age nothing happens.. and no errors.

    using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;

    namespace Retirement { class Program { static void Main(string[] args) { int nr1, nr2, sum; string answer1;

     Console.Write("Welcome! Type your name here:"); string name = Console.ReadLine(); Console.WriteLine("Hello, " + name + " " + ", how old are you? "); nr1 = int.Parse(Console.ReadLine()); nr2 = 65; sum = nr2 - nr1; answer1 = ("You have" + sum + "years until retirement."); if(sum < 0) Console.WriteLine(name + ", " + answer1); Console.ReadLine(); } } 

    }

    What does it mean to be specilized in programming?

    Posted: 29 Jun 2018 07:09 PM PDT

    Does it mean you focus on one language only or create/fix only one type of app? are there programmers out there who can only do one thing and are not very knowledgeable about anything else but still get paid because that thing is popular? How easy is to adapt to another type of app than the one you are specilized at?

    I ask because clients hire developers, they don't specify what specilization they should have except the language maybe.

    Once you know few things about a language, you start creating stuff, should I focus on one popular thing? am I supposed to be good at everything that involves my programming language If I want to find work?
