    Shouldn't all programs start with a MVC (Model-View Controller) or am I wrong here? Ask Programming

    Shouldn't all programs start with a MVC (Model-View Controller) or am I wrong here?

    Posted: 06 Jun 2020 08:49 AM PDT

    I'm still a semi-noob programmer, but isn't an MVC best practice for any code with even mild complexity?

    EDIT* Thanks for the input guys, I think I understand it a bit better. Some of yall have VERY strong opinions this topic though :D

    EDIT** If not a MVC than some kind of similar Event Manager system?

    I gots to learn Java in 1.5 weeks; what do you recommend?

    Posted: 06 Jun 2020 04:24 PM PDT

    I took AP comp sci but failed the AP test and my concepts are incredibly unclear in java, and I currently need to relearn and clear up the concepts in Java in 1.5 weeks. Help. My current plan is to just go through my Barrons book and hope that helps.

    Note: my logic is fine(except recursion lol) just the concepts are bad, like pass by inheritance public static private, polymorphism, casting, etc.

    How do I make a GUI like this, that pops up when you scroll up, and goes away when you scroll down in HTML?

    How would you create a code that looks for deals in Clothing stores ?

    Posted: 06 Jun 2020 04:54 PM PDT

    So I'm a fan of looking for clothing deals online, and right now there are specific items, like a specific pair of shorts that I want from a certain company, but I want to buy them during a sale (normally $50, and during sale $25).

    Problem is, this company doesn't really announce when they put stuff on sale, since they're just constantly updating their online sale with different items, so you kinda just have to stumble upon the deal if you don't want to be checking everyday like a maniac.

    So I want to create a code that basically looks at this website and using the model name of the shorts I want, lets me know when they're on sale. What language(s) do I need to know to do this and is this even possible. Thank you.

    What could go wrong if I forward my own server implementation?

    Posted: 06 Jun 2020 04:50 PM PDT

    I want to try the following as a learning exercise but I want to understand how wrong it could go.

    I'll buy a web domain. I'll load a bare bones hello world http server I wrote in C onto an otherwise empty raspberry pi and plug this into my router with a LAN cable. I'll then port forward the server to my domain (is that the right terminology?) I'll then access the website over a 4G network.

    Can this go horribly wrong? Can the server get hacked and does this matter? What can someone malicious then do?

    What sort of app provides supplemental information to (and on the page) the currently viewed page while browsing?

    Posted: 06 Jun 2020 02:22 PM PDT

    I am not a web engineer. I am business man.

    I have an idea, I wish to see to development and I am trying to understand what it is, I need to ask for. I recall something similar, but vaguely.

    For example:

    Something I could download, that would offer a competitive rate at a different vendor; than the currently viewed site.

    ..

    This information would appear on the same page and I wouldn't have to leave the page to see the price and vendor. I could continue just scrolling along and the information would just appear in a different font or color; in order to for me to distinct visually -easily.

    If anyone can non-condescendingly help me understand or point in the right direction, I would be so grateful.

    Thank you.

    Python file reading

    Posted: 06 Jun 2020 12:46 PM PDT

    Hey guys, I am having trouble figuring out what to do with the question below:

    CompanyA 1.5 4.1 7.6 3.1

    CompanyB 7.0 9.6 6.5 4.9

    CompanyC 6.0 7.0 8.0 8.0

    I am supposed to take the information of this table from another text file to calculate the average with a FOR loop and SPLIT() method and print it like this:

    ​

    Company Average sales Code
    Company A x million dollars LOW
    Company B y million dollars HIGH
    Company C z million dollars HIGH

    I know i am supposed to open the file, but then i don't know what am i supposed to do next? how do i go about calculating numbers from another file?

    ​

    FULL QUESTION BELOW FOR ANYONE WHO WANTS TO SEE ALL THE DETAILS OF THE QUESTION:

    · Open the file for read and read the above information from the file for each company by splitting the data line by line using for loop and split() method.

    · Compute the average of the sales for a four years period to each company.

    · Check if company has an average is less than 4 million dollar. If yes, it will print LOW in the corresponding row, otherwise it prints HIGH, as per the given sample output.

    · The program should print the following output on the screen:

    ​

    Company Average sales Code
    Company A x million dollars LOW
    Company B y million dollars HIGH
    Company C z million dollars HIGH

    Which programming languages have the least job competition per job?

    Posted: 06 Jun 2020 12:36 PM PDT

    Which programming languages have the least job competition. Which programming language specific jobs have the least developers that apply for them per job on average?

    Edit: Which has the least competition per job. Out of C++, Java, Javascript/Web, C#? I don't think I want to learn perl or COBOL lol.

    Is it beneficial to go to university in order to become a game developer?

    Posted: 06 Jun 2020 08:03 AM PDT

    Important context: I live in the UK where college is free but university is around £9000 a year. Also, you cannot drop out of school until you finish college.

    Anyway, I've been hearing recently that in order to become a game dev you don't even have to go to college in the UK. I don't want to get into debt because I don't know if I can save up that much money in the span of two years. Also, it would be nice to start supporting myself properly by the time I'm 18. So, for people who have not been to university and are a game dev, is it good to go to uni, or should I just drop out when I finish college?

    Although I don't know how I'm going to explain this to my Asian parents

    Edit: please elaborate on your answers but a ye or nah is fine as well

    Embeds from reddit not transferring properly to facebook

    Posted: 06 Jun 2020 11:38 AM PDT

    Hey, I'm unsure if this is the right sub to ask, I'm not a coder or programmer, so this is really beyond me. But I'm having issues embedding videos from reddit to facebook. I use the embed option under 'share' and when I post to facebook a grey box comes up with the title of the story/video but it has to be clicked. How do I get a video posted and playable in my feed?

    Thank you for any help!

    Unique RSS feeds

    Posted: 06 Jun 2020 11:27 AM PDT

    Hello Reddit,

    I am building a service that will make use of RSS feeds. Therefore, I am wondering if there is a way to have a unique RSS feed for every user, or if there is a way to know if a specific user is sharing the RSS feed with other users which have not payed for the service. My concern is that a general private RSS feed will just be shared widely unless there is a solution against this.

    Greatly appreciate any help!

    Does anyone has a side project which I can use? Please read...

    Posted: 06 Jun 2020 04:02 PM PDT

    (I am sorry for asking)

    I am a CS student and my final year project is far from complete. I am really interested+invested in it, but I don't think it will be complete before an upcoming deadline ( 15th June), on which I will have to show it to my professors on a video call.

    The thing is that they are expecting the final WORKING project and nothing else. They don't care for what I am trying to do and won't even look at the code at all. They aren't interested in what the project is about, if they don't get to see a complete running project on 15 June, it's going to affect my grades. Most of my classmates even bought projects or paid people to get their projects completed but I am such an idiot that I thought everything will work out, without a plan B.

    Now I am really, really panicked, I can't even focus on my project at all. Please help me out. If anyone has a side project etc which I can show, it will help a LOT. I just need it for a day...

    Or if anyone can show me a repository etc. I am sry...

    Covariance and Contravariance

    Posted: 06 Jun 2020 04:54 AM PDT

    Could anyone please explain about Covariance and Contravariance in programming?.

    As from websearch, I understood these.

    Let say two classes, Animal & Cat. Covariant: a Cat() is an Animal() Contravariant: an Animal() is a Cat().

    Could anyone explain these concepts?

    Having some issues with a for loop in Python 3.7

    Posted: 06 Jun 2020 08:26 AM PDT

    HI! I haven't done programming in a few years, so I'm pretty rusty with it. I'm currently writing some code to generate random tables for a research project this summer. I'm having some issues getting the output I'm looking for. I'm not fully finished with the code yet, but basically, I have 3 lists (both of 4 elements each; prefix, midfix, and suffix list); I want to create a single list out of them by taking the first element from the first list, the first element of the second list, and the first element of the third list; then the second element of the first list, the second element of the second, and so on...
    Right now, when I run the code I have to generate a row out of my rowgen function, I just get a row of 3 elements, the third one from each list (Which is not what I expected at all). Can someone help me out with the rowgen function? I guess I built my for loop wrong. 

    import random import numpy import itertools #import xlsxwriter #List of top 13 most chosen fixes and their probablities of occurance prefixes=[" ","qo","o","ol","l","y","d","r","qol","s","q","sol","dy"] midfixes=["k","che","she","kee","t","ke","te","ch","tee","shee","chee","sh","pche"] suffixes=["dy","y","aiin","al","ol","ar","ain","or","d","s","dar","dal","am"] prefixweights=[0.406,0.283,0.132,0.056,0.046,0.024,0.016,0.008,0.006,0.005,0.005,0.003,0.003] midfixweights=[0.219,0.156,0.134,0.102,0.094,0.092,0.048,0.032,0.030,0.028,0.025,0.022,0.015] suffixweights=[0.397,0.284,0.097,0.058,0.056,0.036,0.020,0.015,0.012,0.008,0.006,0.006,0.005] #Creation of initial table and rows vTable = numpy.zeros(shape=(6,12)) prefixlist=[] midfixlist=[] suffixlist=[] row=[] nrow=12 ncol=6 #Weighted choosing of fixes based on weights above def fixgen(prefixes,prefixweights,midfixes,midfixweights,suffixes,suffixweights): prefixlist = random.choices(population=prefixes,weights=prefixweights,k=4) midfixlist = random.choices(population=midfixes,weights=midfixweights,k=4) suffixlist = random.choices(population=suffixes,weights=suffixweights,k=4) return prefixlist, midfixlist, suffixlist #fixgen creates a single nested list of 3 different lists. This function collapses them #down and recombines the elements to create a row of 4 groupings of fixes. def rowgen(prefixlist, midfixlist, suffixlist, row): for i in range(3): row=[prefixlist[i]]+[midfixlist[i]]+[suffixlist[i]] return row #Creation of table going row by row through fixgen. i ranges only to 4 because 3 fixes are made per cycle #def tablegen(): # for i in range(4): # for j in range (6): # prefixlist=fixgen(prefixes,prefixweights,midfixes,midfixweights,suffixes,suffixweights)[0] midfixlist=fixgen(prefixes,prefixweights,midfixes,midfixweights,suffixes,suffixweights)[1] suffixlist=fixgen(prefixes,prefixweights,midfixes,midfixweights,suffixes,suffixweights)[2] row=rowgen(prefixlist, midfixlist, suffixlist, row) print(row) print(prefixlist) print(midfixlist) print(suffixlist)
