    Is there any interest in a video series building an open source project from scratch?

    Posted: 03 Jul 2019 07:42 AM PDT

    Hi!

    I'm a senior dev here in the UK and I'm currently planning to build an open source project to make deploying C#/.NET applications to Linux easier.

    I intend to build this application using Node.js/Electron for crossplatform capabilities, and wondered if there was any interest in a very detailed video series which would cover the following:

    • Breaking the problems down into managable chunks.
    • Writing clean code to enable code-reuse (DRY), making the project more maintainable and easier to learn from.
    • Proper version control usage. There are plenty of tutorials and interactive guides, but I've rarely seen anything real-world.
    • Implementing a variety of different toolsets and skills, from interacting with remote servers to nice UX.
    • A walkthrough of designing user interfaces that are both functional and nice to use.

    I have a full studio set up at home (both a webcam and a high quality DSLR for in-person recording), a wall-sized whiteboard for thinking outloud, and more. I've been itching to use it, and this seems like the perfect chance.

    All the video would be free to watch, and the code of course would be open source and free to download/use as you wish.

    If this sounds good please let me know, I intend to start today/tomorrow if so :)

    Thanks!

    EDIT:

    Due to the resounding feedback I've Set up a YouTube channel to subscribe to if you're interested!. I'll be posting the first episode within the next couple of days, and I'll post an update in the subreddit for those who would rather wait.

    Is there a personal trainer type of system/guided learning for CS?

    Posted: 03 Jul 2019 10:02 PM PDT

    I've been struggling with consistency in self-studying outside of college for technical/applicable skills because sometimes school or life takes over. Currently, all my school stuff feels too theoretical and I'm unsure how to implement things and complete technical problems. My professors aren't always the most dependable and have a bunch of stuff on their plate, and there aren't very many resources on campus for CS. Is there any online, part-time thing I can pay for where I can get guided feedback for my current position? Part-time bootcamps are way too expensive (17k-30k) so are there any cheaper options (~2k max) for technical interview prep and such? Thanks!

    Hackathon for a beginner

    Posted: 03 Jul 2019 08:06 PM PDT

    I'm a Sophomore CIS Major and was wondering about ways to get my name out there while practicing code. I recently learned about hackathons, which seem pretty intriguing to me.

    Would you recommend a Hackathon to a coding beginner like me? Are they helpful in learning and networking? If not, what better ways are there for networking?

    Cybersecurity as a career path?

    Posted: 03 Jul 2019 05:30 PM PDT

    Currently restarting college (uk) and hopefully I will doing btec computing and game development/design I was planning on going to university and doing a computer science (cyber security) course but I have seen this apprenticeship at GCHQ but If I want to get this apprenticeship I am going to be at a major disadvantage as I am doing a BTEC instead of an A level (got to do a BTEC). I am just wondering if there is anything I can do at home e.g. online courses, certificates, portfolio etc to even the playing field and maybe standout.

    Thanks for any advice/input

    C vs C++

    Posted: 03 Jul 2019 09:10 PM PDT

    Hi, I am trying to learn C. But I have one question. I assume that I can not to do some stuff in C when I can do it in C++. But how does affect me when I program in C instead of C++? What I can do in C++ that I can not to do in C? Why should I use C++ instead of C?

    Online Bootcamps for Developers

    Posted: 03 Jul 2019 05:15 PM PDT

    I'm looking into online bootcamps for software developers that will teach me skills such as SQL, Python, C#, JavaScript, .NET, etc.

    ​

    I'm getting really overwhelmed doing the research and trying to pick one. I'm currently just doing self-studying, learning SQL and Python while working on a data project, but I'm trying to find the right path that will help me the best. I've looked at Tech Academy their bootcamps or just using DataCamp to keep doing a self-study aspect. I've used Khan Academy and Udemy, and other sources before.

    ​

    What are your opinions and experiences with the online bootcamps? Is there any wisdom you can share with me that might help me?

    ​

    (The end goal is to use said skills so I can to get a job.)

    Some questions about Panda Dataframes

    Posted: 03 Jul 2019 09:31 PM PDT

    ​

    So this is just a demo of the real input, I reduced the range down to 2 to keep it simple, it's going to be much higher then that.

    for i in range(2): try: current_line = journal.data[i] current_line = current_line.values() part_zero = current_line[0] part_first = current_line[1] part_second = current_line[2] part_third = current_line[3] part_fourth = current_line[4] print(part_fourth) part_fifth = current_line[5] print(part_fifth) part_sixth = current_line[6] part_seventh = current_line[7] part_eighth = current_line[8] part_nineth = current_line[9] df2 = pd.DataFrame({'A': part_zero, 'B': part_first, 'C': part_second, 'D': part_third, 'E': part_fourth, 'F': part_fifth, 'G': part_sixth, 'H': part_seventh, 'I': part_eighth, 'J': part_nineth}, index=[0]) print(df2) except IndexError: break

    output

    1857838543 2019-07-03T20:08:15+00:00 A B C D ... G H I J 0 37482 68999999.98 16928513209 True ... False 1029434329172 5142406759 1 [1 rows x 10 columns] 92337897 2019-07-03T14:44:32+00:00 A B C D ... G H I J 0 11365 44799999.99 16927659177 True ... False 1029434329172 5142242289 1 [1 rows x 10 columns]

    First of all, why is there a gap between D and G? I printed out the values that are ment to go there, not seeing what's so different about them.

    Second, what's the right way to append to a dataframe? while avoiding duplicating data?

    So that it's [2 rows x 10 columns]

    This program is going to run frequently, so I'm hoping to avoid the exact same dataline taking up multiple rows.

    I tried my luck with df.drop_duplicates, but I must have done it wrong cause it kept deleting a line that had no other duplicate.

    Think that's everything.

    Thanks for any pointers.

    Why is it a lot of projects I see on GitHub have like 5-6 different languages? (Excluding Web Frontend frameworks)

    Posted: 03 Jul 2019 06:44 PM PDT

    A lot of projects I've came across that are written in a lower level language, like C or C++ have files with Objective C, Python, Assembly, etc.. I can understand those scripts can probably do things independently, what is the actual reason people have that many different languages?

    Java program to create an index with the list of ngrams (e.g. bigrams) contained in these documents along with the number of times the ngrams were found across all documents.

    Posted: 03 Jul 2019 11:59 PM PDT

    Hi,

    I am relatively new with Java programing.

    I am given a set of text documents (i.e. text files) in input, and I need to create an index with the list of ngrams (e.g. bigrams) contained in these documents along with the number of times the ngrams were found across all documents and the list of files where the ngrams appear.

    ​

    Output
    The output should be a file that contains the list of ngrams (e.g. bigrams) identified in the documents in input, along with the number of times the ngram was found across all documents and the list of files where the ngrams where found. For example 

    a collection 1 file01.txt a network 1 file01.txt a part 1 file03.txt hadoop is 2 file01.txt file03.txt

    The Java program must receive 4 arguments as follows: 

    args[0]: The value N for the ngram. For example, if the user is interested only in bigrams, then args[0]=2. args[1]: The minimum count for an ngram to be included in the output file. For example, if the user is interested only in ngrams that appear at least 10 times across the whole set of documents, then args[1]=10. args[2]: The directory containing the files in input. For example, args[2]="/tmp/input/" args[3]: The directory where the output file will be stored. For example, args[3]="/tmp/output/"

    ​

    ​

    I have started by tokenizing the sentences in the files into an array of words, but I am not sure how to proceed.
    Any suggestion or help would be much appreciated.

    Thanks

    Semi - learn programming - related question: What is a really comfortable chair for my desk?

    Posted: 03 Jul 2019 11:23 PM PDT

    As programmers, our asses are sitting a good bit. As a college student, I'm going to be spending hours upon hours at my desk studying. I figured that just as I have invested in a great laptop, I might as well invest in a great chair. What are some good chairs that are under 500 dollars? Would gaming chairs be a good place to look? Thanks, everyone :)

    Best offline learning tools for Python

    Posted: 03 Jul 2019 10:51 PM PDT

    Of course there's books and what not, but some of the online courses I'm dabbling in hold my hand so to speak as I work through the program - the problem is that I often find myself offline. I'd like something I could download that'd help guide me more until I can get out of the beginner stage - anyone have any leads?

    Facial feature analysis sorting program?

    Posted: 03 Jul 2019 06:56 PM PDT

    Hey guys,

    Firstly I guess I should start by saying my knowledge of programming goes barely further than a "hello world" and the various types of languages. I took a two courses in high school that covered pascal, C+, and Java but never touched it ever since and have forgotten the basics. So I know the general gist of programming but am no where near having an idea and building it on my own.

    Anyways, I'm wondering how difficult it would be to create a facial analysis program for photos from a google search? My idea would be to scan the web page for several sets of conditions (eye color, hair color, wrinkles, roundness, ect.) and then sort those based on those conditions. I imagine sorting things wouldn't be that difficult but creating a detailed algorithm which identifies what is in the photos would be the hard part, right? I'm thinking this is almost facial recognition software expect without a reference photo or model.

    This is probably way too advanced for a first project but would it be possible to extremely simplify the idea and then continue to enhance it over time? First learn to store things (photos) from the internet, then sort those photos based on simpler conditions like (cats,dogs,birds,outdoor,ect.), then improve the recognition algorithm over time? Not really sure what this would take but these are just my ideas from knowing a little bit of programming.

    What language would be best for this? I'm seeing html for pulling things from the web browser then something that's good at algorithms lol.

    The ODIN Project vs University of Helsinki Fullstackopen?

    Posted: 03 Jul 2019 07:48 AM PDT

    As someone wanting to dive into modern web development, which one do you think would be best? For learning purposes and also for building up a github.

    ​

    I saw yesterday that The Odin Project released a fullstack javascript version of their program, and Helsinki seems to dive right into React from the get go, so it seems to be slightly more modern and to the point to me. Does anybody have any opinions on which one would be best?

    Want to help a friend, don't know how...

    Posted: 03 Jul 2019 06:31 PM PDT

    Hello. I'm just wanting to do something for my friend. They're sorta always in their room and I'd like to be there for them but due to geographical factors, I can't.

    I want to try learn how to program a button that when pressed, sends an alert to my phone. It's so that I know when to message my friend when theyre up or bored because they suck at communicating but I dont blame them for that. I dont know if its possible for that but thats why I'm here lol. Maybe setting the button to display a notification connected to an app? I dont know how it would work honestly, but I think you'll get the idea if you can help.

    Any responses would help a ton. Thanks! <3 - Concerned Friend

    can anyone explain this

    Posted: 03 Jul 2019 06:08 PM PDT

    Write a class named Octagon that extends the abstract class GeometricObject and implements the interfaces Comparable and Cloneable. Assume that all eight sides of the octagon are of equal size. The area can be computed using the following formula: area = (2+4/sqrt(2))sideside Write a test program that creates an Octagon object with the side value 8 and displays it's area and perimeter (to 2 decimal places). Create a new object using the clone method and create a method that compares the two objects (Octagon object and clone object) and returns true if all data elements are the same in both objects, false if any data object is different.

    I'm confused. What am I suppose to putting in the GeometricObject class? It doesnt even say anything. Comparable and Cloneable, are these classes am suppose to be making?

    Align a table by char? Html5 took this away, so now want can u do?

    Posted: 03 Jul 2019 09:51 PM PDT

    I'm in a web dev class and the videos said we can use align="char char="." To align a table data cell by the ".". But since it's been removed in html5 I can't find a way to do this in css. After along Google session ppl have used span tags around the . To add padding and force aligning around it. But if my table has a lot of numbers I don't feel span gaging them all is right. Is there a better way?

    What should I learn next?

    Posted: 03 Jul 2019 09:39 PM PDT

    In total I took 3 classes in Java (including data structures and algorithms). I was wondering what should I learn to help me apply for software engineering positions. Learn web development? Learn cloud computing? Make an app on Android? Learn Java Spring (not really sure what it is but heard it's in demand)? I bought cracking the coding interview book so I can study for interviews but I just need to be able to get an interview. I'm considering taking a course on Udemy because a lot of the courses build projects that can be helpful for my CV. Any advice on what specifically I should learn after having a good knowledge of object oriented programming in Java?

    Interactive Video Quizzes - Coded by hand?

    Posted: 03 Jul 2019 09:20 PM PDT

    I'm trying to find an answer for this, and hopefully this is the right place to go...

    Is there a way to code interactive videos with quizzes by hand? I'm assuming with HTML/CSS/JS, but I'm open to ideas.

    Something along the lines of Camtasia interactive quizzes, Adobe Captivate, Articulate 360 etc.

    I'm essentially trying to find a "free" (read: use my coding brain instead of dollars) solution to those platforms.

    Any help or a point in the right direction is appreciated. Thanks!

    Comfortable with the fundamentals of Javascript and I want to work on a chrome extension, where do I begin?

    Took a few courses in JS. I'm already pretty experienced with programming in other languages but wanted to get into web dev.

    I want to make a chrome extension that basically grabs ratings from ratemyprofessor and puts it into my schools registration page. A nudge in the right direction would be helpful. How do I scrape data from a webpage and put it into another?
