| Posted: 06 Jan 2020 11:49 AM PST TLDR; please subscribe if you would like to join: https://www.youtube.com/channel/UCuiHDgG-Vzkg4wbaCe9nczQ It all started with this post: https://www.reddit.com/r/learnprogramming/comments/ejefqw/im_thinking_about_running_a_python_course_for/ I have never ever posted a video online, I'm an introvert but now it's almost a moral obligation to make this channel if there's such a high demand. My vision is to have a course for absolute beginners that's formed by the community, I want to interact with you. If you watch a course on e.g. Udemy or subscribe for a channel that already uploaded all the lessons -> that's static material, there's no feedback from you. It would be way more powerful to make these sessions with you, answer your questions in real-time and guide you to improve yourselves session by session. I'll set up a small website where you can sign in and I'll give you homework/challenges. You will get some input data and a task and you have to produce an output. The site will automatically check your results. Based on how all of you do these challenges I'll know your weaknesses and we can work on them. I would like to teach you JavaScript as well. Python is awesome but creating command line applications are not so exciting (it can be!) so it would be better to create interactive web applications with Python Flask back-end. That's powerful! Furthermore working 10+ years at large companies in challenging environments I would also give you "I wish I knew it before" career advice. (I worked myself up from a small city in Hungary to the City of London where I work as a data engineer/developer/consultant at one of the largest companies globally.) I'll upload a video later with more details on the course but I'm still waiting for the camera tripod and the microphone. Below you can find the link for my channel, please subscribe if you would like to join the course:https://www.youtube.com/channel/UCuiHDgG-Vzkg4wbaCe9nczQ [link] [comments]  |
| Minimum moves to solve 15 puzzle (with varying sizes) Posted: 06 Jan 2020 11:29 PM PST The 15 puzzle is given as so: You are given a 2d array of size between 2x2 and 5x5, or any combination in between (3x4 is allowed, 2x5 is allowed, etc). The array is filled with all numbers from 0 to MxN - 1, where MxN is the size of the array. These numbers are unsorted. Find the minimum number of moves to sort the array, where a move is defined as swapping 0 with any number up, down, right, or left of it, if the array were to be laid out as a grid. (Imagine 0 is the empty tile, if it helps). If it is impossible, return -1. If my description still doesn't make sense, here is a link to the 15 puzzle: link This question absolutely stumped me in an internship coding challenge. Hardest question I've ever seen in a challenge like this. Got 3/10 of the test cases, and only because I could see them. What do you guys think, leetcode hard? Please post your solutions.

| Posted: 06 Jan 2020 05:22 PM PST https://databasic.io/en/wordcounter/results/5e13d700a8de6104dfb273b4 I am totally new to looking into getting into the software engineering field. I started looking for info in Google searches and on Reddit and YouTube. But it's hard to separate the hype for various trends, and people trying to promote their products, from what's actually significant. So I looked at bunch of SWE job listings at big companies, ran the text of all of their "requirements" and "qualifications" sections through a word counter, and deleted all the fluff words (experience, ability, demonstrated, etc). Here's what I found:
My conclusions, as someone going into this process:

What can I do to better myself? The reason I am asking the things that are asked I never encountered those types of situations in my career. Anyone else experience this? [link] [comments]  |
| [React] Why does my first state not update until after one submit Posted: 06 Jan 2020 08:58 PM PST Hi, I've been working on FullstackOpen and my code is working but I'm just wondering how to render the useState during the first event handler. After I submit my form to 'add a user to phonebook.' My useState 'setID(persons.id)' will trigger as '0' on my first event handler. I'm guessing that it performs asynchronous (from googling) so I would have to find a way to trigger it so that the state updates at the same time but I'm kind of lost on how to do so. It works after the first event handler but I know this is not the right way to use useState. What should I change so that id is changed before my first submit? Thanks

| Just finished my first program in Python. Would really appreciate a code review Posted: 06 Jan 2020 04:28 PM PST Hello everyone! I've been enthusiastically learning programming/python and I just got done writing my first program that's not just "Hello World!". It's a simple program that tracks the ISS in real time using an API. It then stores the coordinates into a SQLite database along with a timestamp. It also shows who is on board and on the craft. It runs and it does everything that I intended it to do but I just can't help but shake the feeling that I'm not doing something right or that I could be doing something better. Is this a normal feeling after completing a project? Anyway, I would love to hear what you all think. Thanks! The API is generously provided by the Open Notify project. [link] [comments]  |

| Beginner's confusion on career.Kindly help me. Posted: 06 Jan 2020 11:54 PM PST Hello subreddit programmers greetings, I am a beginner in C# and have learned it. Now i came through a job which uses fair bunch of trending concepts such as MVC, MVVM, things, etc. They've said work will be on the product which was built and there is a space for lot of bug recovery, maintainence, etc. Type of job seems i'd be doing a fair bunch of maintainence plus developing little.(I appreciate it indeed). I am a newbie. Would be it helpful for me to move on development. Would you prefer this role for me ? Please sprinkle your thoughts and guidance. I appreciate them. Thanks in Advance.

| Would you be interested in practicing skills with real-world programming tasks? Posted: 06 Jan 2020 05:54 PM PST Hi everyone! I was wondering is there a tool/free service that helps developers to practice with the real-world problems in their domain? By real-world problems, I mean the actual tasks that developers deal with on a daily basis. As an example, what should be the next step for a person who is on the way to become a backend developer and already learned basic algorithms and specifics of his stack/language but is not confident enough to start contributing to OS projects and is not sure if having enough knowledge to start looking for a job? While investigating this topic I discovered one project ( HackerRank Projects ), which as I understood has a similar idea but is paid and interviewer/business oriented (You even can't start a trial there without company's email address). The other similar approach is the project based learning, but I am looking for a tool that feels more like on-the-job scenarios. Don't get me wrong, in my opinion, the project-based learning is a really great way to learn to code and to train for future work, but probably you would agree that very often the challenges that you get while working on the inherited codebases are different from the ones that you can get while implementing sieve of Eratosthenes or bootstrapping Todo list clone from scratch. Thank you very much for your time! I would greatly appreciate every opinion/idea/advice on this topic! P.S Just in case you got interested and was looking for a tool like that, please feel free to sign up to this newsletter, I will keep you posted about interesting links and investigations from this topic.

| San Francisco Meetups for Data Science Posted: 06 Jan 2020 11:38 PM PST Hello everyone! In 3 days I am taking a plane from Barcelona to San Francisco where I will be starting a new life with my wife. I would like to know if anyone has suggestions on what Meetup (or other platforms) groups would be good for a beginner interested in Data Science like me. I have been doing some Python and Data Science courses during the last months but I am still what you would consider a novice (this is actually my first post on Reddit). Linking with people with experience whom I could run things through, get some support, and slowly start to build a network would be great! I have been looking into the r/learnprogramming , r/learnpython, and r/Python subreddits and did not find any similar post except this one but it is 4 years old, so I decided to post this. If there are any other posts similar to this, apologies in advance. Hopefully, this is also useful for other people in my situation. Anyway, thanks in advance and good luck in this 2020.

| Opinions on Code Chrysalis, a coding bootcamp in Tokyo? Posted: 06 Jan 2020 11:31 PM PST Hi people. Long story short, about 1 year or so ago I have previously done a coding bootcamp before with Le Wagon. While it was extremely intense, I feel that they did not touch on the fundamentals at all, which I strongly believe is very important, as I want to be able to pick a new tool(language) and do things with it, not tied to a language. Overall Le Wagon was a crazy experience, and indeed I learned many things, but the number of knowledge gaps were also many. I then stumbled upon another coding bootcamp called Code Chrysalis, but this one seems different. Allow me to say why:
Ultimately, as good as Code Chrysalis sounds, will it be similar to Le Wagon? Where everything feels rushed, that I don't even know what is happening behind the scenes? Or will it be different in a good way - teaching fundamentals, going at a fast pace BUT making sure the students understand what is happening under the hood, etc.? As an example, I learned SQL too with Le Wagon. But man....if you want me to be perfectly honest, I have ZERO idea what was happening under the hood. It was just me like a robot - writing SQL queries without truly understanding anything. Another example, cloning an AirBNB. I "completed" it, but without actually understanding many many things. I had a LOT of questions while creating the AirBNB clone. My concern is, will Chrysalis be like this? Are they just another coding bootcamp that markets itself really, really well? OR are they actually as good as they say? I welcome any and all constructive ideas/opinions/feedback/criticism especially from those who have done Code Chrysalis. Thank you for reading [link] [comments]  |
| Posted: 06 Jan 2020 11:02 PM PST I learned C and C++ as my first languages and only learned back end development. I want to make my programs more user friendly and wanted to explore front end to spice up my projects. Is it efficient to do it with C or C++ or should I learn another language like Java? Also if you do suggest learning another language, how do you get the different languages to communicate with each other? [link] [comments]  |
| Posted: 06 Jan 2020 10:58 PM PST It happens all the time. Just today I had a simple problem aligning elements. So I created a separate project and got it working there, then did the same thing in my own project and it worked. I usually only do it if I get stuck to a point where I'm struggling. While it's helpful I feel like I'm wasting quite a bit of time. I admittedly don't use version control and just revert back to a working version very often. I should probably force myself to do this instead, but I don't know. Then I have to commit code and I may not have committed before starting on the next thing and have half-working bits in there. Thoughts? [link] [comments]  |
| Combination of Two Lists Python Posted: 06 Jan 2020 10:55 PM PST I'm trying to combine two lists, first I'll combine same two lists, later with the result I'll combine the list again over again. item_list = [("a"), ("b"), ("c"), ("d"), ("e"), ("f")] first output is this; [['a,b', 'a,c', 'a,d', 'a,e', 'a,f'], ['b,c', 'b,d', 'b,e', 'b,f'], ['c,d', 'c,e', 'c,f'], ['d,e', 'd,f'], ['e,f']] (Until here it works) next output should be like this: ABC ABD ABE ABF ACD ACE ACF ADE ADF AEF BCD BCE BCF BDE BDF BEF CDE CDF CEF DEF on and on, the and the last output will be ('a' 'b' 'c' 'd' 'e' 'f') here is my code; So what it's doing is, it pops and holds the first index of the one list and creates a list full of what its holding. Later concatenates it with item_list. Problem is at the first combination ['a,b', 'a,c', 'a,d', 'a,e', 'a,f'] is being popped instead of 'a,b' only. Is there a way to map them seperately so whole list won't be popped? Or any other efficient way to combinate them using the map function? [link] [comments]  |
| 101+ Coding Interview Problems with Detailed Solutions, Test Cases, and Program Analysis Posted: 06 Jan 2020 04:56 PM PST Hi friends, 4 months ago, I made a reddit post on creating a newsletter that sends out 3-6 coding interview problems with details solutions every week. To my surprise, the post received a lot of attention and positive feedbacks from the community. Since the total number of problems and solutions has just passed 101, I would like to say another big thank you all again for all the support. It really helps me keep going. Moving on, I am hoping to add more questions and then finally condense them into a list of most frequently appeared coding interview problems that I think are the most valuable and productive to spend time on. Again, my goal has always been to help you get good at algorithms and data structures so that you can prepare better for your next coding interviews. For those who don't know, here is the link to all 101+ questions and solutions, sorted by resources → If you're interested in getting updates for this, feel free to check out my blog and join my mail list here.

| Posted: 06 Jan 2020 06:56 PM PST I have been learning python for a few weeks and am wanting to start working with spreadsheets. I am following a tutorial for using openpyxl. I put " pip install openpyxl " in the terminal to instal it and it said it was a success, but when I tried to use the command " from openpyxl import Workbook " it has an error and says " No module named 'openpyxl' ". How do I solve this? I have been using the guide at https://realpython.com/openpyxl-excel-spreadsheets-python/ for reference. [link] [comments]  |

| Closing a different Window in WindowBuilder (Java) Posted: 06 Jan 2020 10:15 PM PST Hey guys, first time posting So I'm currently working on a text based game similar to The Oregon Trail (I know Java is probably not the best game making language out there, but it's all I know). I'm working with opening and closing windows and on each window I'm putting data in. There is one part where I have a shop menu open with adding and subtracting buttons and when the player is finished adding stuff to their cart I want to open a window to double check their cart. This window opens and shows their cart and I want them to be able to revise it and if it's wrong, close the window and add the missing items. This is easy to do because I can code the check out button to open the cart check window and a cancel button to close the cart check button. My problem comes where I want to open the cart check window and if everything is okay the "confirm" button closes both the cart check and shop menu button, but I can't do this because the dispose() method isn't static so I can't call it on Shop Menu. Is there any other ways to close two different windows with a button on one window? [link] [comments]  |
