| any learning material on the logic of OOP? Posted: 18 Oct 2020 09:54 PM PDT I am not sure if this kind of question is typical / allowed on here; but basically, I am teaching myself javascript and am still very new and do not study computer science in college but I do study logic. I have been looking for material/books on the fundamental logic behind object-oriented programming in general but have noticed a lack of material related to this subject. I've been getting on fine learning the syntax and practical application but I am itching to understand the fundamental principles behind OOP and cannot seem to find any in-depth material on the subject. Can anyone recommend me any books that cover this subject in particular? Everything I have found has been either very basic and surface-level or focusing entirely on practical particulars.

| Posted: 18 Oct 2020 11:50 AM PDT My schools curiculum has been updated and we started learning C and C++ , I wanted to join a C online course but while reserching I came across the idea that "C is not a good place to start coding , and that python would be better " . I dont know whats true , maybe the answer is not so black and white but i would appreciate your opinion. [link] [comments] |
| A not too hard Python task that I'm having trouble as a beginning Posted: 18 Oct 2020 08:02 PM PDT Hello everyone, So I've just started learning Python a few weeks ago, and I have an assignment that I've been a bit stuck on. I am a total noob at Python so I was a bit embarrassed to even ask this, so go easy on me please! The task is to find all fields in a column with the substring "TO", since the column is full of numbers such as 283948TO297874. I have to find each of these instances, split these strings into two columns using "TO" as the delimiter, then when a number is entered that is between the two numbers in the columns (so I'd use a range function I think), I have to return the ID of the row where the original string originated. So far my attempts have been: df1[['LEFT NUM', 'RIGHT NUM']] = df1['LEC Circuit ID-A'].str.split('TO', expand=True), and tmpDF = pd.DataFrame(columns=['A','B']) tmpDF[['A','B']] = df1['LEC Circuit ID-A'].str.split('TO', expand=True) but they both return an error "Columns must be same length as key" I'm kind of stuck and afraid of the people at StackOverflow, so I appreciate any help I get here. Thanks. [link] [comments] |
| Posted: 18 Oct 2020 08:58 AM PDT I'm a Linux sysadmin with very little coding experience. I was asked to develop a demo RCS chatbot in nodejs that would echo back any message it gets. I'm surprised I even got as far as I did, and I only have one last thing to do. I'm really enjoying this project and I was hoping I could ask for some help for the last piece. There are a couple of types of messages that get sent to the bot. It receives a message when someone is typing, sending a picture or a text message. I'm trying to only listen for text messages and extract
This is example of a text I sent to the bot: and this is an example of when someone is typing: This is the part of the code that prints incoming messages to the console:
My question is, is it possible to extract Huge thanks ahead! [link] [comments] |

| Need help with intro programming work Posted: 18 Oct 2020 05:28 PM PDT I'm working on classwork for my intro to programming class and need some help with methods with multiple parameters. I've tried everything that I could think of, but I cant figure out what I'm doing wrong and how to fix it. Would someone be able to help me write methods correctly? I know this is probably basic stuff, but I'm so lost. This is the (hopefully) the link to the code I have written so far. I believe if I can figure out how to write one method correctly, I should be able to do the rest of my assignments on my own. [link] [comments] |
| Split a 2d NumPy array into 2 separate 2d arrays based on a column value Posted: 18 Oct 2020 07:53 PM PDT So I have this 2d array that looks something like this [[1,2,4],[1,4,4],[2,2,4],[2,5,9]] The first column in this array can only ever be a 1 or a 2, I want to split this 2d array into 2 smaller 2d arrays, with all the arrays where the first column equals 1 are in and another where all the arrays whos column 1 has 2 in it. I am new to numpy and have seen some examples and documents online but i can't seem to get exactly what I want. Here is the current code I am trying to use ```
``` I am basically trying to split the trainingData(which is my array) into 2 separate arrays, but when I run this I get more than 2 arrays. If someone could point me on the right path that would be great! Thank you [link] [comments] |
| Posted: 18 Oct 2020 12:15 PM PDT Hi all, The goal of this little project is to create a personal dashboard, something i can load up and pulls from different sources to get weather, calendar, stock prices, etc from the internet. My objective is to have a working useful dashboard but going through the process of learning to build it and making it my own is important too. I've been doing a lot of research on the best route to take here, the main languages I know are Python and JavaScript, so the two I've been pushed towards the most are PyQt (which doesn't seem to make the best looking products, correct me if i'm wrong), and Electron (which is bloated AF!). My 2 questions are: Happy to provide any more info is required. Thanks in advance everyone! [link] [comments] |
| Total noob question about importing a module. Posted: 18 Oct 2020 03:38 PM PDT This should be the easiest thing in the world, but somehow I'm stumped. It's not even my own code, I'm simply following along with a tutorial, but for some reason it's not working. I created a module in one file, and I'm simply trying to import it to another file. The two files are in the same directory, but it's telling me the "module doesn't exist". Here is the original module, named "Classes.ipynb": And here is the other file, where I'm trying to import it: Here's the error I get: Any help would be greatly appreciated! [link] [comments] |
| Modern Website with one page per recipe for 500+ recipes. Posted: 18 Oct 2020 01:34 PM PDT I'm working on a personal project and don't have much experience with modern web design or infrastructure. I am not a developer, I'm more of a data scientist and have experience with big data and data infrastructure design. Essentially, my family has written a cookbook that has recipes that have been passed down through generations. This is a physical book that we have made copies of and have updated through the decades. I was looking into bringing it into the modern age and turning the book into a website with a page for each recipe. (approx. 500 recipes) I'm looking for some help on how to design this website. My original plan was to use WordPress and just manually create 500+ pages for each recipe, but that would be miserable and I'm sure there is a clever way to do this. I created a sqlite database that has columns for the Recipe Name, Category, and Text. The text is both the ingredients + the instructions, but I can parse those out into separate columns if necessary. A friend had suggested that I can use React to create a dynamic page for each row in my database, is this actually possible? I have tried googling this kind of project but haven't found anything relevant. I don't really know what to google. Would React be the best way to do this? Can anyone suggest the best way to create a website like this? Or how they would implement it given the same requirements? -Home Page with a Nav Bar - About Page - Recipe Categories Page (click on a category to see list of recipes ie. breads, sides, etc) - 1 Page per recipe for 500+ different recipes (all in the same format) - A search bar to look up by recipe name As far as hosting, my plan was to just use LightSail from AWS.

| Facebook Marketplace Automation tool Posted: 18 Oct 2020 05:01 PM PDT Hi all, i'm wondering if someone can point me in the right direction or to the right person. I am in need of someone to develop some code for me, the code needs to be able to go into Facebook Market Place and automatically create an item listing using photos from a folder in my laptop,
I sell a lot of items on FaceBook market place and manually listing is a pain! [link] [comments] |
| Posted: 18 Oct 2020 10:50 AM PDT I am currently using pycharm as my IDE and, as the title asks, is it possible to have a live background in your IDE? I already know about normal background customization, but wonder if someone knows about this type of thing. [link] [comments] |
| How to display text on an official paper form? Posted: 18 Oct 2020 03:36 PM PDT I need to display text on an official paper form. My idea is to just show the form as a background image, and then using absolute css positioning, just display the text wherever I need it. The idea is, users need to be able to print the form or export it as a PDF. Take this form for example: https://i2.wp.com/www.formspdf.com/wp-content/uploads/2017/10/Official-business-forms.png Does that seem like a good solution? How would you do it? Any better ideas?

| Using an eReader/Kindle for reading technical/programming book? Posted: 18 Oct 2020 11:35 AM PDT Sorry if this is off topic, wasn't sure which sub would be best to ask this question. Do any of you use a kindle for reading technical/programming books? I'm wondering if these types of books are annoying to read using one. Code examples are many times dependent on font/indentation/formatting, etc. I'm not sure if eReaders screw with that. I've been wanting to devote more time to reading technical books. I constantly buy technical books and then never read them. I've been thinking about buying a Kindle, like the one with the liquid paper screen. I feel like if I had easier access to the books, I'd be more likely to read them. Plus they let you bookmark stuff easier. [link] [comments] |
| How long should it take to fix a bug/add a new feature to a 3000 line code? Posted: 18 Oct 2020 07:36 AM PDT I've been working on this code for 2 weeks with the goal of fixing 2 bugs and adding a new feature. I've fixed 1 bug, temp fixed another, and have been unsuccessful in adding the new feature. I'm new to corporate programming so I'm not sure what the expectations are. My lead programmer gives me arbitrary dates like 3-4 days away and extensions if I need. However it sucks asking for an extension every 4 days. Everyday I get closer to understanding the code, but it doesn't feel like progress. (You know the feeling right?) Question- what are expectations here? This is obviously something with a huge range, but that is what I'm looking for. Days, weeks, months? [link] [comments] |
| [PHP][Mysql] sleep() is causing entire database becoming inaccessible Posted: 18 Oct 2020 07:13 AM PDT I ran into this issue today and I'm not sure what to do with it. Here is a simplified scenario:
Issue is. During the 10 seconds of sleep time. All pages that make connection/contact with database basically stop loading. network tab shows (pending) on the page request....UNTIL the sleep(10) function is done then pages load on their own. Running SHOW OPEN TABLES on PHPMYADMIN during the sleep timer shows all tables with [in use] column being 0 for all tables. I tried even tried running: before setting auto_commit to false but it seems to have no effect. I can't see myself submitting a project knowing that pages will be inaccessible until all transactions being run by all users are done loading. [link] [comments] |
| What are cool projects to build using C#? Posted: 18 Oct 2020 07:09 AM PDT I'm going to keep this short but I finished my first web development project (built with pure HTML & CSS) back in June and successfully launched it! I took a long break from developing afterwards and then got back into going over my C# fundamentals since I currently work with C# at my job (I don't directly write C# now) but past projects I did. I now find myself unclear of what to build. I have ideas but none seem to be obtainable and I feel like most projects are common ones. I just need some ideas or motivation to start my next project to add to my portfolio. Right now I am up to the challenge to building web apps with ASP .NET or even desktop apps for windows. Doesn't matter to me! Building something is better than nothing plus I want to fill this void of not programming since at my current job I barely write any code or if I do it's not an entire projects worth so I want to make sure I keep my programming thinking and skills intact without degrading.

The only problem is I've never used an API before or built a web app? I am, however, an advanced student of Java, what are my options here? What can I do? What resources are avaliable? I can put in the work; thank you in advance. [link] [comments] |
| What technology/language should I learn as a budding developer Posted: 18 Oct 2020 09:41 AM PDT I am working as a software developer in a corporate company for the past 3 years. I learned how web apps work, how to find and solve complex problems, how to write efficient code and many more. But the problem is, I feel like I am working on some out dated technologies like servlets, emberJs, java, C++. I see a lot of people working on newer things like ML, react etc., I feel like I have to be updated to survive. So please advice on what should I start to learn now to move to next step in software domain. Sorry for my bad english. [link] [comments] |
| How should I approach building a receipt scanner app [Python, Java, and Javascript] Posted: 18 Oct 2020 09:13 AM PDT I want to develop an Android app that scans supermarket receipts, extracts the data, and spits out XML/JSON file. Then the extracted file will be caught by a web-app running with React.js, where it'll be visualized as graphs, diagrams with react's pretty GUI libraries. How should I approach this? I know that But I can't simply imagine how to implement these 3 different frameworks to work in unison to achieve my plans. How should I do it? Should I stick to pure python despite the fact that Android studio's python support is poor? Thanks a lot! [link] [comments] |
