    Do coding boot camps make you employable?

    Posted: 25 Jun 2020 08:40 AM PDT

    Are coding bootcamps worth it?

    As this is a lengthy post and you don't want to read the background I just put my questions at the bottom. Thank you for any advice.

    I just found out I am having twins and I am 19. I am currently a college student and will be transferring to online however now I have to provide for a family of 4. I am looking at attending Flat Iron. I have basic coding knowledge of python but my college courses were only gen eds so I don't have any CS knowledge from them. I went for CS because I really want to do software engineering not just web development. I am fearful after training and experience in web development, software companies won't hire me due to my experience being in web dev not software. As a clarification I will be getting my degree in CS. This would be used as a jump start. Sorry for the lengthy post in advance.

    Questions Do coding bootcamps give you enough knowledge to be employed? Does anyone have experience with Flat Iron? If I do web development would it be hard to switch to software engineering after the fact?

    Edit: Since this is blowing up so much (thank EVERYONE for the support,) if you didn't do a code boot camp what would you do? Resources and languages etc. in order?

    Best way to learn

    Posted: 25 Jun 2020 07:04 PM PDT

    If I follow a video tutorial on YouTube, what's the best way to learn. Is it best to take notes, code alongside or do both?

    Are coding "apprenticeships" a thing like a plumber or mechanic?

    Posted: 25 Jun 2020 06:04 PM PDT

    Learning on my own is a struggle. I have been trying for 5 years now and feel like I have made zero progress. I can't afford school and feel like it is becoming hopeless now. I am wondering if an "apprenticeship" is even a thing in the field to maybe try my luck at that if possible.

    Is it considered good practice for functions to return value?

    Posted: 26 Jun 2020 12:11 AM PDT

    I am asking this because I have been solving coding problems on a website and the function they want me to write is always return some type of value and is that because of test reasons or good practice? Because I have been learning C# and sometimes it is easier for functions to be void.

    I have one year to get a job. Can I get something programming related with daily study for a year ?

    Posted: 25 Jun 2020 11:42 PM PDT

    I am a shitty husband and have been leeching off of my wife for too long. We have a year long trip coming up, where we will be in Asia living and neither of us will be working. We aren't poor, we have no kids, but she is the breadwinner and I'm the house husband. And I feel like there's no better situation than a time limit for me to finally do something real.

    Sorry for that. Just needed to share. Anyway, I wonder if it's possible to become self taught in programming and land a job in a year. I've read about automation engineers being hired with little more than basic knowledge of programming, and wondered if this sort of thing is attainable in a year. Or if there are Any other jobs attainable in a year of learning.

    How can programming be used to get an advantage in marketing/used for marketing in general?

    Posted: 25 Jun 2020 11:20 PM PDT

    Hello,

    How can programming be used to do marketing, or give me an advantage in marketing? Are there ways to build programs to do marketing for free, automatically, or to give an advantage over my competitors?

    I've really been interested in digital marketing lately, but I can't seem to find any resources on how to use programming to benefit digital marketing.

    What are your resources for this? Do you currently work in marketing and use programming? I think my goal is to be able to build a program for digital marketing and then use that as a service to provide to people. I'm not talking about platforms for marketing that are made with code (like instaon.io) but more like tools that I can build to help with it and give an advantage in it.

    I would love to get my hands on some resources to help me learn more about this. I've been learning programming, networking, and computer science by myself for over a year now, on and off, so I know most of the technical stuff behind it works. Don't be afraid to add technical stuff to your comment if you have one that could help.

    Thanks, guys and gals.

    For the people that learned java in college, what did they teach you?

    Posted: 25 Jun 2020 04:23 PM PDT

    I'm a high school student going into college later this year and I wanted to get a headstart by learning some concepts ahead of time. I know it depends on the college but anything goes at this point.

    How to be coding-smart?

    Posted: 25 Jun 2020 09:32 PM PDT

    I only started with C through Harvard's free Computer Science course (CS50) 3 months ago (on week 5, though), and with C++ since it's the first language tackled in my college. I can understand the concepts well and the examples of how a variable or any concept is used, but everytime I tackle a problem set in CS50, my mind goes black. I always try to write a psuedocode that helps me understand what to do step by step, but then I ask "Wait.... How do I implement that step?". Then, I end up finding a solution that I didn't write and think "Oh, it was that simple to apply". My problem is my mind goes blank if an activity is not parallel to a lesson's example. How do I become able to code from scratch to complete an activity based on what I've learned? Everytime I try something, it's either that it's wrongly written and messy, or it isalmost there.

    Edit:
    tl;dr: I learn concepts with examples, get presented with an activity to complete, then brain goes blank.

    ELI5: What's the difference between wide-column stores (like Cassandra or HBase) vs a regular table in a database?

    Posted: 25 Jun 2020 09:20 PM PDT

    Sorry if this is the wrong sub to post this, but I'm new to software development and don't know where else to ask this. This might be a really stupid question, but I can't wrap my head around the advantages a wide-column store provides over a regular table. I know wide-column stores supposedly are faster to load and query, but how? From the diagrams that I've seen, a wide-column store is pretty much identical to a regular table, except that the column label is attached to each individual entry across the table (as seen in this image: https://studio3t.com/wp-content/uploads/2017/12/cassandra-column-family-example.png?x13993).

    I'm taking a Systems Design course and the current module is how to design a Facebook messenger type service. It mentions that RDBMS like MySQL or NoSQL like MongoDB (which I believe is a document store) won't be any good in this use-case since the system can't afford "to read/write a row from the database every time a user receives/sends a message. This will not only make the basic operations of our service run with high latency but also create a huge load on databases". It instead recommends using a wide-column store - but wouldn't we have to write a row for each column family and read from it every time a message is sent/received?

    Is it worth your time to follow up on these offers from people who see your tutorial/technical blog post and want to add it to their publication? Feels kind of spammy?

    Posted: 25 Jun 2020 08:35 PM PDT

    Wrote a blog article about how to set up a simple app in Vue.js for testing CRUD ops like when using new libraries. Just got three offers to add the article to publications. Not sure if they actually read the article or just approach anyone who writes something like that. Of course I would love to get more views/engagement, but I'm wondering if there's a downside here? Here's a screenshot of the offers with names blurred

    Are arrays in C dynamic by default?

    Posted: 26 Jun 2020 12:10 AM PDT

    I'm learning C and C++ side by side right now.

    I noticed that arrays in C always have dynamic behavior, where it doesn't need to know the size at compile-time. While in C++, we'd have to use vectors or the new/delete operators to create dynamic arrays, since normal arrays can't have a dynamic size.

    So are arrays in C dynamic by default?

    Thank you.

    So I learned the basics of C++. Now I want to make projects. Should I go with game dev or Qt?

    Posted: 25 Jun 2020 11:38 PM PDT

    Hello

    I learned C++ and made the basics stuff with it: management systems like this, re-implementing data structures and I have taken an opengl class in university which used C++.

    The thing is, I got all the basics and now want to write something BIGGER. I am thinking of either a low level game with GLFW or SDL especially that I know opengl and have made games before using parser.js, android ..etc. or QT because I know PyQT, which is a python wrapper for this library.

    I am fine with either of them. But my problem now is I want to learn PROPER c++ usage. So which library/framework should I start with?

    By proper I mean the one with least quirks as possible. Some libraries in other language enforce bad habits and weird programming ways. With that in mind, which should I try first?

    People working with Git on your job, do you use Git with GUI or use it in Bash/cmd?

    Posted: 25 Jun 2020 11:35 PM PDT

    So I have been learning and practicing Git for past few days in Bash, and I just found out there is a GUI version of Git. I found this out at the tutorials I've been watching, specifically thenewbostons, who switched halfway through to GUI version.

    Now I am curious, is it used in work environments and if you use it, do people gatekeep by saying you should use console instead of GUI?

    Leetcode prerequisites

    Posted: 25 Jun 2020 11:23 PM PDT

    I have only taken 1 unit of java programming at university which did not contain any algorithms or data structures. I want to start practicing leetcode problems so that in 1.5 years until I graduate I become good at them. Could you please let me know what are some prerequisite to start on easy problems? Right now I don't understand them.

    Learning Paths Series: Machine Learning

    Posted: 25 Jun 2020 03:49 PM PDT

    Guide #2 of my Learning Paths Series is about Machine learning. I learned it a while ago and this guide includes the best resources I found.

    This guide dives into the theory and mathematics behind machine learning. This not an "over the surface" guide. Math is included because it's important for an understanding of the "mechanics" of ML.

    Disclaimer: I'm not affiliated with any of the resources and am not about to receive any type of compensation for including any of them here. This is an objective guide.

    My guides include 4 Categories:

    1. General Resources - Resources to use along the whole learning process
    2. Beginner - Your entry point for learning
    3. Intermediate
    4. Advanced

    General Resources:

    1. Sentdex - A great YouTube channel
    2. Kaggle - Your Machine Learning and Data Science Community. This is a very recommended practicing platform to test your ML abilities. Use it extensively, compare your results to past winners of competitions, and check your improvement. Always practice.
    3. awesome-machine-learning - A curated list of awesome Machine Learning frameworks, libraries, and software
    4. Data Stack Exchange - From the family of Stack Overflow
    5. r/learnmachinelearning - subreddit for ML learners
    6. r/MachineLearning - subreddit for ML practitioners

    Beginner:

    1. Machine Learning on Coursera - Make this your first Course. It's a minified version of the real Stanford course and it's a nice first encounter with the concepts of Machine Learning, doing it hands-on.
    2. https://www.kaggle.com/learn/python - Become more proficient in Python, the language that's behind many of the pro ML libraries.
    3. fast.ai - Introduction to machine learning for Coders. This course is a great hands-on course. It uses current ML libraries, environment, and is centered around Jupyter notebooks and Kaggle practice.
    4. Single Variable Calculus - MIT OCW free calculus course. A great refresher for some and an important first time for others. If you enjoyed it and want to be able to dive deeper even more quickly for ML, take Multivariable Calculus from MIT OCW as well.
    5. Linear Algebra - MIT OCW free linear algebra course. A great refresher for some and an important first time for others.

    Intermediate:

    1. Andrew Ng's Machine Learning - The full course from Stanford, full lectures touching theory as well. Very recommended, even though you probably took the Coursera version. This is something else.
    2. Learning From Data - A great Caltech course, on the theory behind popular ML algorithms.

    Advanced:

    1. Machine Learning - A Probabilistic Perspective
    2. Next, where to go from here? - Explore fields such as Neural Networks, Deep Learning, Computer Vision, and more.

    Can Nodemailer only send emails from your own account? Will it allow a user to send it from their own?

    Posted: 25 Jun 2020 10:49 PM PDT

    I have set up nodemailer on my portfolio to allow people to contact me. There is a mail options object with from & sender as some of the options you can set. I have my code accepting whatever email address is entered in and if I have my server take what was inserted in the from field and set it to the cc field then it will at least send that email a copy as well, but no matter what the email is actually being sent from my own email. Is that expected? Is there a secure way to use nodemailer to allow a user that visits my portfolio to actually send me an email from their own email? The only way I could conceptualize this is if I make the user enter in their password, which is something I def dont want the user to do.

    Heres my transport...

    const transport = nodemailer.createTransport({
    service: 'gmail',
    auth: {
    user: 'justinpaoletta@gmail.com',
    pass: process.env.PASSWORD,
    },
    });

    I really just want to confirm that nodemailer is ONLY for letting a user send me an email from my own address to my own address. Also if I'm wrong and there is a way to have the user send an email from their own email to mine please guide me to where I can find that info. I see nothing in the nodemailer documentation confirming this.

    Thanks a bunch!

    C++ Key detection

    Posted: 25 Jun 2020 10:31 PM PDT

    I want to detect key presses for my program, I know two ways: GetAsyncKeyState and _getch. The thing is, when I make an infinite loop for GetAsyncKeyState, it uses up way too much CPU to just detect key presses.

    I can set up _getch in a switch statement and do it fine, but _getch doesnt detect certain keys I.E VK_ADD, or VK_CONTROL

    I need to know if there is a way to either make AsyncKeyState infinite loop less CPU hungry, or have it set in a switch statement.

    Or maybe if there is just some other thing I can use that is much better than the options I know

    Python nested yield in for loop

    Posted: 25 Jun 2020 10:15 PM PDT

    Hello I have a program i need to write that, it works like this:

    1. send POST request to get token
    2. use token to GET all main categories in ecommerce platform
    3. then i have to travel down all categories and get all the leaves - that is final categories in tree without any subcategory - that also means i send GET request for each subcategory and then check if it returns "leaf" == True (this is flag in returned JSON)
    4. if it is a "leaf", it is a final action and for them I have to GET all required parameters
    5. subcategories might be of varying lenghts - e.g."Electronics > Smartphone accessories > Earphones > Wireless" = length 4, but "House and garden > garden tools > lawn mowers" = length 3
    6. I want to save it all in JSON

    This should expand to nice nested JSON that is a collection of all categories and their subcategories. That on the end points - that is final subcategories there shoud be "parameters": Table that stores all the parameters.

    So to me (and I have started seriously learning programming with Scheme/Racket) it seems like a recursive problem that should call itself in all subcategories and then end in the "leaf" for which I just make a last call to GET parameters and end recurrsion. I use yield statement instead of return with for loop inside of recurrsive function ...... Yes this is what I thought should work.

    def get_all_leaves(category_tree): for category in category_tree["categories"]: if category["leaf"] == True: request_parameters = requests.get("https://api.allegro.pl.allegrosandbox.pl/sale/categories/" + category["id"] + "/parameters", headers=headers_main_category_tree) dict_parameters = json.loads(request_parameters.text) yield {"name":category["name"], "id":category["id"], "parameters":dict_parameters["parameters"]} else: request_id = category["id"] next_category_tree = requests.get("https://api.allegro.pl.allegrosandbox.pl/sale/categories?parent.id=" + request_id, headers=headers_main_category_tree) dict_next_category_tree = json.loads(next_category_tree.text) yield {"name":category["name"], "id":category["id"], "subcategory":get_all_leaves(dict_next_category_tree)} 

    And this is result of print(list(get_all_leaves(json_main_category_tree)))

    [{{'name': 'Dom i Ogród', 'id': '5', 'subcategory': <generator object get_all_leaves at 0x03F7D6F0>}, {'name': 'Dziecko', 'id': '11763', 'subcategory': <generator object get_all_leaves at 0x03F7D878>}, {'name': 'Elektronika', 'id': '42540aec-367a-4e5e-b411-17c09b08e41f', 'subcategory': <generator object get_all_leaves at 0x03F7D808>}, {'name': 'Firma i usługi', 'id': '4bd97d96-f0ff-46cb-a52c-2992bd972bb1', 'subcategory': <generator object get_all_leaves at 0x03F7DA70>}, ... ... ... {'name': 'Wyposażenie', 'id': '123', 'subcategory': <generator object get_all_leaves at 0x03FCF760>}] 

    That is is it worked in someway, it looks like a recurssion but it put generators inside a generator ? They are not expanding themselves.

    MobaXTerm Help

    Posted: 25 Jun 2020 04:03 PM PDT

    Hi everyone! Ok, so I am going to ask a homework question. I have never posted a homework question on any subreddits, but I'm really struggling here. I don't just want the exact correct answer. I am really trying to understand what this question is asking in the first place and why the command is what it is. I'm just taking an intro to shell script short course and the TA has been hard to get a hold of so far - and also tends to just give the answer instead of explaining the 'why'. For background, I'm working on a shared Neches cluster and I'm using MobaXTerm on Windows. If I've missed any background information please let me know. Here's the question:

    Write a function that takes a directory name as an argument and writes to standard output the maximum of the lengths of all filenames in that directory. If the function's argument is not a directory name, write an error message to standard output and exit with nonzero status.

    Less "Where to start?" more "What to start?"

    Posted: 25 Jun 2020 05:40 PM PDT

    I don't know that it's very relevant, but to whom it may concern I'm a 21yr old female living in a fairly remote part of the US with little financial support. Taking that into consideration I concluded that learning to code from home would be among the most viable career options for me. I know there's plenty of resources here to start with just about any language, but I don't know what's worth taking the time to crack away at. I'll take a moment to list my objectives in this pursuit in hopes somebody might be able to point me in the right direction.

    1) Educating myself remotely

    2) Educating myself without incurring massive debt

    3) Eventually working remotely

    4) Having consistent demand for this work

    5) Making enough from my work to stay above the poverty line

    Unfortunately, I don't have the luxury of taking passion into account. As someone looking at this career purely from a business perspective I am asking...

    TL;DR: Where is the work? Where is the money? Where is the demand? You will have my eternal gratitude for sincerely answering these questions,
