    Thought of sharing this treasure!! List of websites to learn coding!

    Posted: 28 Dec 2019 05:32 AM PST

    Below are websites having numbers of courses and resources you can access free of cost mostly. Happy Learning!!

    P.S- shared.

    Edit:1 Thanks guys for adding more sites in comments. People might be having lot of suggestions. Pls include those sites in URL format rather than hyperlink.

    Edit:2 Understood.. This is a lot to take in for beginners. Instead of biting cheese on all plates you find, just focus on one and eat full. That way you would know the progress.

    34 Year Old, Beginner Wanting to Start a Career in Programming

    Posted: 28 Dec 2019 08:20 PM PST

    Hey guys, I am looking for advice from anyone willing to offer it. I'll just lay it all out on the table by being completely honest: I am 34 years old and just started programming this year. I want to be a software developer for mobile apps. I have no prior experience in anything IT and am only just starting to learn. I'm doing this because I want a practical, in-demand skill which has a future and can command a good salary. I am 100% determined to put in the work , and quite honestly, I love the challenge that will come as I advance. I have been studying Python since November through a Udemy course and so far, I only know basic data types and operators; in addition, I am just getting into for-while loops. I chose Python because it was recommended as a great language to get your feet wet in.

    But time is not necessarily on my side, and while I have done some research and have some idea as to how to go forward, it would be great if someone could share a similar experience? Maybe offer some great way to go forward on this? Maybe help me find a practical way to advance to advance my career?

    For example:

    I have a BA, so should I get a Masters in Computer Science(as s Software Engineer) or continue with Udemy? If I choose the latter, I suppose I could learn to build software on my own and then go into the job market?

    If I become proficient in Python in a few months, would I be able to work for a company as a junior developer? Or maybe some kind of helping hand as part of a large team and work my way up the ranks?

    Could I work as part of a team(as mentioned above) while putting myself through college(if I go the Masters route)?

    Do I need to be certified in Python? Is a Certificate even worth the $1,000-$2,000?

    Are coding boot camps a good way to go? I don't think so, but maybe.

    Anything would help. Thank you.

    An Intro to Numba: Make your Python fast like C

    Posted: 28 Dec 2019 08:53 PM PST

    I've been making Youtube videos lately (mostly about text editors) and finally made one about programming. It's a fairly thorough intro to Numba that contextualizes its uses in a real world example and demonstrates a number of beginner pitfalls. Hoping someone can find it helpful.

    What is flashing firmware and how do you do it?

    Posted: 28 Dec 2019 11:17 PM PST

    Recently I've gotten into Arduino programming and I've heard about something called flashing a device or say bluetooth module. But I'm confused on several things. 1 What exactly is flashing, is it me compiling code to the Arduino or pfogramming with a module? And 2 how do you do it?

    Ideas on how to login to any website with a set of credentials via crawler/headless browser (Golang)

    Posted: 28 Dec 2019 07:47 PM PST

    Hey all, I'm working on a project where I'll need to login to various different websites with a headless browser or crawler of some sort. I am thinking of using https://github.com/chromedp/chromedp and Golang at this time.

    Now I can hardcode a way to login to a specific site fairly easily, but I want to make this a bit more dynamic than that. As of now, I'm thinking of crawling and finding the login page, then searching for inputs with username/email and password within them. Even if I get to that point, I know it won't be 100% accurate, but that's ok. But was curious if there's other ideas on implementing this in an easier or better way. Any advice is greatly appreciated!

    How often is too often to post on StackOverflow?

    Posted: 28 Dec 2019 08:38 PM PST

    I don't want to abuse the site, but on the other hand: As long as you've tried to solve the problem yourself for some time, done your Googling, and read the results that come up, is there anything wrong with posting multiple questions per day? (I would consider that an extreme, but just for conversation's sake.)

    For context I'm a newb programmer who has lots of questions and occasionally solves problems on his own.

    Need help with splitting Strings into a String Array in Java

    Posted: 28 Dec 2019 04:21 PM PST

    I have a Spreadsheet as a .txt file and I need to split each row into an Array for further calculations each value is divided by a ",".

    My Problem is some values have quotation marks and inside these quotation marks, they use commas. How can I separate the values without splitting the value inside the quotation marks?

    Example row:

    1000,117090058,117970084,"170,9 + 58","179,7 + 84","Flensburg Weiche, W 203 - Flensburg Grenze",Flensburg-Weiche - Flensb. Gr

    what topics should I cover to get good at programming in Java?

    Posted: 28 Dec 2019 11:47 PM PST

    I just finished my first class this semester in programming and it went okay. We learned about basic stuff like creating method,arrays and calling class. They hardest thing we did was insertion sorting(still don't understand). I was wondering can you guys give me a list of topics to learn

    My Boggle Puzzle Solver is Very Slow

    Posted: 28 Dec 2019 07:58 PM PST

    Hey y'all,

    I've been making my own version of Boggle this week in Java. The gist of the game is you spell as many words as possible that you can find on a 5x5 board. Beyond checking for user inputted words that are valid, I want to catalog all possible valid words.

    And there lies the rub. My puzzle solver is VERY slow. Right now, I'm only checking for words 9 letters or smaller and that is 5,410,793 iterations. It takes around 10-15 seconds. Ideally, I will check for words 15 letters or smaller.

    As far as useful information:

    • My dictionary is about 400,000 words
    • I store my dictionary as individual Strings in a HashSet. (Creating the Set takes about 800ms, precomputed) I haven't done any sort of HashCode overwriting.
    • the main slowdown in the algorithm is the dictionary lookup. It can take up to 1500 nanoseconds. I perform the look up via Set's "contains" method.
    • My solver is recursive. (Maybe I can improve speed by removing recursion?)
    • I can't perform DFS/BFS because reaching the same tile isn't independent of path.
    • I can't memoize my algorithm because it is possible to have the same word appear in multiple places on the puzzle and still have different longer words.

    The only solution I can really think of (which is too involved for me to try doing in the next couple days) is to add a training set and create an AI that is smarter about the search. Pretty much train it to not continue a search path for bad input (I.e. learn that no words start with "gzb")

    Do you have any ideas for how I can speed this up? I imagine it will have to do with a smarter data structure for storing the dictionary.

    Should I do mathematical operations in language vs database?

    Posted: 28 Dec 2019 11:39 PM PST

    what i mean is:

    for example, i have number 19.123142, and i want users to see this as 19, should i do it in database, with round() function, or should i do it in language?, is database suited for this kind of stuff?

    Is codeacdemy a good website to learn python?

    Posted: 28 Dec 2019 02:54 PM PST

    So I am a teenager who has started learning python on codeacdemy, and I am enjoying it very much. I was just wondering if there were any other resources or websites that would be better. I was also recommended automate the boring stuff and find that helpful too, and would like to find more that would help.

    Implementing segment tree to tell if given part of array is sorted or not

    Posted: 28 Dec 2019 11:23 PM PST

    I wanted to solve a problem where an array is given like int arr[] = { 1, 3, 2, 7, 9, 11 };and I have to found out if given range of array is sorted or not. One method is described here it uses array traversal which takes O(n).

    I want to learn so I am trying to do this through segment tree. Here is my code. I am able to arrange data in segment tree correctly. But retrieving result from given segment tree is failing.

    It would be great if some can point out the mistake or tell me any better way I could have implemented that in segment tree.

    Reality of getting a remote job

    Posted: 28 Dec 2019 11:52 AM PST

    Hey all! So I'm thinking about learning to code, right now I have NO CLUE about anything in this field. Long story short, I have been in some other field before, but I want to switch and I have to be able to work remote. So let's say I spend 1-2 years learning on how to code full time, how likely will it be for me to get a remote job and earn somewhat decent money? Is this a big risk when not having a degree and being self taught? Ofcourse, lets say I become somewhat decent at this. Its almost like I feel it might be too late to get into this in 2020, but I guess im wrong? I probably seem very clueless about this, and yes, I am. Thank you.

    What to do next?

    Posted: 28 Dec 2019 10:42 PM PST

    I'm currently working through the automate the boring stuff course on udemy, and I have acouple questions.

    There doesnt seem to be very much actully coding practice. How do I know that I'm retaining the information?

    Should I follow along and watch, maybe try a few things in the command line to make sure I understand?

    Or should I be trying to take notes on everything.

    Where can I go for very beginner level practice?

    How do you know youre making real progress?

    Created a website to help students aiming for GSoC select Organizations conveniently.

    Posted: 28 Dec 2019 02:02 AM PST

    With December almost over, its high time to gear up for Google Summer of Code (GSoC) 2020. First and most crucial step in the preparation is selecting the Organization that you would want to contribute to.

    This is quite painstaking as you have to go through hundred's of organizations, find if they use the language or framework which you are proficient in and more. To make matters worse, Official GSoC website does not allow you to search organizations using language or framework.

    To ease this, I've put together a website which lists all the organizations, the no of years they were selected and technologies (language and frameworks) that they use. You can search the language you are proficient in, and export the table in pdf,excel format etc.

    Honest opinion on Coursera ?

    Posted: 28 Dec 2019 06:46 PM PST

    I want to start lerning programming, and Coursera keeps coming back when i look for lessons.

    Most of the links I found on OSSU send me back to coursera, and they come top when i look on google, and it was the second link on one of the post here (" Thought of sharing this treasure!! List of websites to learn coding! ")

    It looks really interesting, i do not mind too much paying, because I really want to learn properly. Moreover if I am paying it is going to be one more incentive to study what I pay for.

    However, I started to read review about coursera, and what i found was frightening: https://www.consumeraffairs.com/education/online-courses/coursera.html?#sort=top_reviews&filter=2

    Anyone has tried it and could tell me the real value of Coursera ?

    Tutorials have their place..

    Posted: 28 Dec 2019 10:06 PM PST

    How does one transition from tutorials to actually building stuff on your own? In order to build something you have to know the basics, which is where good ol tutorials come in. But how do you move away from that when it's hard to even remember how to write code when there's an empty text editor in front of you! Please share experiences and advice.

    Anywhere to learn web site design by daily or weekly challenges

    Posted: 28 Dec 2019 05:49 PM PST

    Is there anywhere I can learn web site design through challenges. Heres an example of what I'm looking for. They give you a topic or so and they then give like a list of requirements. It must include a navigation bar, you must use 3 different types of fonts, ect. It's pretty hard finding motivation to make a website sicen i don't know what to make. I have tried, but it's really hard to think of an idea. I'm not even really trying to make a useful website, just learn design.

    Do I need to learn about data structures and algorithms if my goal is to be a front-end developer

    Posted: 28 Dec 2019 03:12 PM PST

    Hi, I recently started coding with the goal of landing a front-end developer job. Through reading articles and watching random youtube videos on programming, I've heard a lot about data structures and algorithms. I've heard a lot of large tech companies value knowledge in this area of computer science. I am wondering if it is important for me to learn these topics if I am primarily focusing on front-end tools such html/css/javascript. I eventually will get into back-end and was thinking of holding off on learning about data structures and algorithms until I get there

    I need some pointers with this Excel "tool" and SQL

    Posted: 28 Dec 2019 09:08 PM PST

    I have this workbook in Excel that is designed to do a number of calculations based and generate an output. Is there a way to retrieve records from a database (say MS SQL Server) one by one, push it through the worksheet, and write it back to the db? I am still trying to wrap my head around the concept...

    So far, it seems to me that I should be looking at how to create an Excel Add-In. The Add-In would have custom functions that query the database, loop through the records and inputting each one in the worksheet, and saving the results. Is this even possible / Am I on the right track?

    Is it true? Really ML and python are over hyped!?

    Posted: 28 Dec 2019 08:56 PM PST

    Is ML/AI pretty over hyped field with lot of education centers claiming lot of stupid things? Trying to get people to spend money on courses?

    Already I'm demotivated after hearing from the guy who has been working on the field for 3+ years.

    I just started learning stuffs and all of sudden I'm hearing this kinda derailing from the course.
