    Is Mac necessary? Ask Programming

    Is Mac necessary?

    Posted: 04 Nov 2020 08:37 AM PST

    Hey guys , maybe a silly question . I have a windows pc and windows laptop right now , but all I see is MacBook in the developer industry. I'm wondering if it's necessary to get one? I work mainly in Java right now but I'm a toying with the idea of web development too ? Thanks in advance and sorry if it's a noob question 😅

    What is the best way to remove a coding roadblock and progress?

    Posted: 04 Nov 2020 04:09 PM PST

    I've always been interested in computers and I've been poking into code for a while. When I started out I started with web development and soon after I moved into python. However, whenever I try moving onto bigger projects, I always find gaps in my learning or immense total roadblocks that I can't overcome.

    I know I can ask subreddits such as r/learnpython but when helpful people there answer, I can never seem to understand the solution. I think this is because I'm self taught from places like YouTube and it feels like I have tons of small gaps in my knowledge that don't let me progress. I know tools such as Codecademy and Leetcode exist, but those always end up being either too slow paced or too fast for me. Additionally, I feel like most books I've gone through mainly cover basics that I know.

    Example: I know python basics and I have a light grasp over classes. I tried to diversify into socket programming with python and I immediately ran into roadblocks. I was able to find help and find guides and use that to progress, but I actually wasn't understanding the code.

    Anyways the question is: Is there any recommended way to progress in programming in general?

    I know people recommend, "learn the basics and then make a project and learn on the way". However, this method never really worked for me.

    Getting a remote job as my first position.

    Posted: 04 Nov 2020 05:42 PM PST

    Hi, I've been programming for about 3 years now using javascript and python. Javascript being my primary language using nodejs, mongodb and express. Long story short I'm converting a bus to live on the road. I will have a computer setup and an internet connection. I have never had a programming job so I am wondering the likelihood of landing a remote position as my first programming job? I could freelance but I'm hoping for something more stable. Any input would be wonderful. Thank you!

    What program to use for large data which requires excel like manipulation

    Posted: 04 Nov 2020 04:09 PM PST

    I currently do data migration activities which requires lots of data manipulation. However I am finding the quantity of data (fields*rows) is at times problematic as it exceeds, loosely speaking 250,000+. Excel is the current tool of choice but when data exceeds this number, roughly speaking, excel slows down too much as the size of data becomes too large. This is exacerbated by the method used, which is pertinent for auditing, where information is duplicated to show clearly how manipulation to data is carried out. So 250,000 cells can become 1,000,000. With all cells being formula driven. Volatile functions are not used, some vba is used But even when fully automated the size is the issue. The manipulations carried out would be simple stuff like Vlookups, IF statements, removing accents from words/stripping down to English alphabet usage characters, formatting phone numbers to be uniform based on country area code, extracting bank details from a provided larger bank information such as IBAN or CLABE and so forth. Nothing too strenuous but visibility on original and output greatly facilitate the process as this will include working with non techie people.

    In addition, on a separate workbook a reconciliation is carried out which on a 250,000 cell worksheet would have about 750,000 formulas(original, migrated, check). Need to have clear visibility of the original, the after, and the errors/differences.

    I have used python and sql independent to this work. I'm not an expert on them but I feel something can be done with them but not limited to using them e.g. using pandas + something else??

    I am trying to understand what can be done, if possible, to allow for the same ease of use excel offers, where non tech people can see what's happening, but which can handle much larger data sets with ease.

    I have looked into power pivot but I believe that doesn't solve the issue as that just creates a connection and the pivot table connection is just as slow as working with excel. I think powerpivot is just a great way to merge a lot of data together from multiple sources. Happy to be told otherwise.

    Am I asking for something which doesn't exist or is there a solution which exists? I'm really keen to hear any opinions on this.

    TypeError: cannot unpack non-iterable NoneType object

    Posted: 04 Nov 2020 07:42 PM PST

    I am testing code that will render the number of frames based on the episode count for a custom openAI gym env.

    here is my original working code:

    if render: self._init_plt() self._render(obs) if self.episode_count % self.sample_freq == 0: self.export_frames() self.episode_count += 1 return obs, action, done #return obs, action, render also worked here

    here is what I would like to change it to. I am new to python, so I am not sure if this is an indentation or python problem, or openAI gym. I think it has something to do with python, because return obs, action, done worked fine in the previous code snippet.

    the variables I refer to:

     self.reward_range = (-1, 1) self.episode_count= 0 self.frames_freq = 10

    new code snippet:

    ​

     def should_render(self): return self.render and self.episode_count % self.frames_freq == 0 if self.should_render(episode_count): self.init_plt() self._render(obs) self.export_frames() self.episode_count += 1 return obs, action, render

    The error I get:

     obs, reward, done = env.step(obs, action, render=True) TypeError: cannot unpack non-iterable NoneType object

    I am completely lost at what could be causing it.

    I made a website with Python, but when I deploy it on Netlify, it can't be found. But on my localhost, it works just fine. Why is this?

    Is there a subreddit I can use?

    Posted: 04 Nov 2020 02:12 PM PST

    Hi, I recently started studying programming (C language) and I'm finding it a little hard. I've read the rules of multiple subreddits and all of them forbid asking for a full code or for a full solution. I got this code that's giving me trouble. Is there a subreddit or maybe a different page where I can ask for that? Can I use this subreddit?

    I hope my post doesn't get removed just for asking as well.

    What is the least compressed image format?

    Posted: 04 Nov 2020 05:13 PM PST

    I wanted to know what the most/raw primitive type of image is. Like something that's just a 2d array of RGB codes for each position or something with no regard to space conservation or anything.

    Style and efficiency

    Posted: 04 Nov 2020 10:20 AM PST

    Hi all, I saw a headline a few months ago about how having a company/team style guide, no matter what the style, can save programmers hours of time.

    The main point of the article was about how time is lost when two or more coders work on a project with different personal styles.

    Does anyone have a link to that or know where would be a good place to look?

    Thanks a million

    Databases and Barcode question

    Posted: 04 Nov 2020 01:30 AM PST

    Hey everyone! I am fairly new to databases and willing to learn, but I have a few questions. Maybe someone can tell where should I start.I am trying to create a solution for my works warehouse.

    The whole idea goes like this :

    We print out labels with unique barcodes and paste them on our boxes. The printing software (BarTender) saves our labels + barcodes in a .csv file. After the boxes are packed, the .csv file is being sent to our warehouse employee who can verify that the boxes match the list (the .csv file) by scanning each unique barcode.

    What have I done already :

    I have already setup the printing software, bought a zebra android barcode scanner and made sure that the .csv files are made correctly.

    The question :

    What solution you would recommend for me? I need some sort of automation, where an employee could just scan the barcodes on the boxes and it would somehow verify in a database by a barcode that the specific row is correct and Import it into the "stock".

    • Is there already a solution for this one?
    • If I am creating this from scratch, where should I start?

    I am sorry if this kind of question was already posted here, or this is the wrong sub. If there is another place where I should ask this kind of question, please tell meThanks

    Approving / Merging

    Posted: 04 Nov 2020 11:38 AM PST

    I had a conversation with someone I work with over approvals and merging pr's.

    In yall's experience, is the approver also the one who merges the code. Or is it the one who wrote the code that should press the merge button?

    I've always done it one way over the other and am curious what other's practices are.

    Need help extracting data and importing it to facebook, no idea where to begin research.

    Posted: 04 Nov 2020 01:47 PM PST

    I'm a co-founder of a small automotive marketing company doing facebook retargeting.

    For the record, cloud based/server based applications/programs are COMPLETELY foreign to me. Anything I've had to code/pay people to code has been for offline applications.

    Part of what we do requires us to generate CSV files containing vehicle information and import them to facebook in their catalog CSV format.

    So far we've been doing this manually every other day using free solutions (Scrapy, Parsehub, etc) to scrape the data from websites, run an excel macro to convert the data into a CSV that facebook can recognize, and uploading manually. Naturally as we begin onboarding more clients this has become a tiresome task that I feel could be automated. I have no idea where to even being researching how this might work.

    We can pull the Data from two different sources. I can either scrape from the websites (convenient because I can do this on my own schedule) and reformat the data, but we depend on scraping tools (usually parsehub) to do this. Alternatively the dealership's inventory software has an API to pull data from I haven't experimented with yet.

    The route I'm thinking is to somehow set up a program to pull the data from the dealer inventory management software (they have an API), reformat it into the Facebook CSV format, and upload it to a URL for facebook to pull from on a schedule. I would also need to pull/upload vehicle images to a URL for importing to the facebook catalog.

    I guess my question is, where do I begin researching how to build online datafeeds like this? Would this be something where I would need to setup a server to run this program or have a cloud service like AWS run it?

    I don't even know what this kind of programming is called. I feel really in-over-my-head with this. If anyone could point me in the right direction I would greatly appreciate it.

    TL;DR. I need to automatically pull data from APIs, convert the data into Facebook Catalog's CSV format, and host it on a URL facebook can access along with image files from the API. What should I start researching to learn how this works?

    Javascript Question

    Posted: 04 Nov 2020 09:20 AM PST

    To be completely transparent, this was an interview question that I just had, and I didn't know the answer to it. Even though that boat has sailed, I still want to know.

    Write a wrap function that takes the execute function as an argument and returns a modified function so that the following requirements are met:

    Any result returned by the function execute should be returned from the modified function unchanged.

    If the function execute throws an error, the modified function should return null.

    After the function execute has thrown an error, its future executions should be prevented and null should be returned.

    Multiple wrapped functions can coexist.

    The execute function doesn't take any arguments.

    Use - https://jsfiddle.net/ or similar to write in your language of choice

    ​

    function wrap (execute) {

    // Return modified function

    }

    ​

    var errorExec = wrap(function () {

    throw new Error('Error');

    });

    var resultExec = wrap(function () {

    return "Result";

    });

    console.log(errorExec && errorExec()); // Should output null

    console.log(errorExec && resultExec()); // Should output "Result"

    Server architecture question

    Posted: 04 Nov 2020 08:57 AM PST

    Hi all got a question regarding a backend architecture. I want the backend to be able to accept post requests from several downstream IoT devices and then be able to notify a web UI using SSE with this data. Whats the best way to architect this e.g should the SSE broker and the endpoints that accept posts to "/data" be on the same server? Is this even possible? The above would be my initial implementation but in the future will be adding a database ect and want to get the architecture right from the outset. Going to write the backend in go. Thanks in advance!

    Physics simulation engine

    Posted: 04 Nov 2020 12:27 PM PST

    Hey all, First a bit of backstory: I am a 16 year old from northern Germany and all schools in my country have now opened with the obligation to open the windows for some extendet periods of time during the day. Since I am one of the students that always sits next to the window I wanted to simulate to what temperatures the room cools down to (if for example it is 10 degrees outside and the window is open for 5 minutes).

    Since I am kind of proficient in python I already looked for a engine that could simulate something like that. The best i could find was manim which goes into the right direction but is not really what I need.

    Ideally I want to be able to give my program a model of my class room (which I made in blender or something similar) which also has a place for every student and their 37 degrees of temperature and the temperatures inside and outside and the time how long the window is open. I already thought about writing it myself but I think I won't be able to finish such a project in time for when the real winter is here.

    Is there a library that can do this for me or is there an even better way I'm just not seeing because of my lack of experience?

    Student struggling with learning Java

    Posted: 04 Nov 2020 10:54 AM PST

    I don't know if this is the correct subreddit to post this on, but here it goes.

    I am studying applied computer science in Oslo. This is my first time both studying and learning coding and programming. We have a subjected called programming where we learn Java, and I must admit that I struggle quite a lot and I feel anxious about the upcoming exams because I dont feel prepared. We are learning Java on a very basic level, but I still find it quite hard to understand. Things I struggle with the most are class and objects, arrays and for/while loops.

    My question is, how can I better understand Java?

    [C] How do I edit a variable and it changes the array?

    Let's say I make a variable, char a, and an array, char plot[3][3]. I want to be able to set a = 'X', and it changes plot[0][0] = 'X' too. I'm not too familiar with pointers, but I feel like this is the way to do it. Any help would be nice.

    I tried char *a = &plot[0][0] and char *a = plot[0][0] to no avail...

    Looking to contribute to a project which helps our environment/nature.

    Posted: 04 Nov 2020 03:06 AM PST

    Hey everyone,

    I'm a programmer with some free time on his hands, and I am looking to contribute to a project/projects which contribute to our environment. The environment is important to me, and I'd like to utilize what I'm good at, to do my part.

    edit: I am looking for project to help on a large scale. Not just the local environment. For instance, projects which deal with solar energy and climate change. Projects which rather help our planet.

    Is anyone aware of these projects, which could use a programmer?

    Thanks!

    Suggestions on a input/output coding question online website in different languages?

    Posted: 04 Nov 2020 07:18 AM PST

    With remote interviews being a thing, we're having difficulties with giving coding questions out. It's an issue with the setup and somewhat our explanation, which might be able to be addressed with a better setup.

    I'm looking for a website that allows a developer to pseudo code or code in their preferred language a solution to where we give an input, and we have an expected output.

    The goal being to see how they achieve that goal.

    Do you guys have any suggestions about this? What are your opinions on small coding questions in 2020?

    Thanks

    A script for copying Excel values to a different app (Python)

    Posted: 04 Nov 2020 02:29 AM PST

    Hello everyone,

    I am not a programmer but I am interested in a lot. I am working in a company and we have a system for guest registration. When there is a visitor to the company, I have to write their names, surnames, ID numbers, position, car plate numbers, etc. to an application called Lotus Notes. This is very time consuming and I am planning to write a script. We are getting an excel table of visitors with these informations so the script should open the excel file, copy the informations and paste them into the Lotus Note app and it should do that to the right columns.

    If you can help me with some examples or and kind of idea, I would be really glad.

    Thanks !
