    Posted: 18 Mar 2019 01:23 PM PDT

    This is a huge blow to my confidence tbh.

    Bill gates said that in all of his years of development, he's never seen a single developer that sucked/was mediocre that went on to be a great developer after this 3-4 year period.

    I'm at this range and I'm no where near ready to be a senior and I'm still considered a junior/mid level based on my skills.

    I really don't want to be stuck at this level but at the same time there's this guy who is one of the most successful programmers/intellectuals of our time just telling it like it is.

    I don't want to believe him at all. I know people always talk about shitty programmers but does anyone have any anecdotes of someone who was terrible that eventually became great?

    I asked this on cscareerquestions, got severely downvoted, and many people in the comments agreed with him and said they've never seen someone go from sucking to becoming great.

    "J'Accuse!" A text-based mystery game written in Python

    Posted: 18 Mar 2019 01:15 PM PDT

    I'm creating a series of short, simple, text-based games in Python that beginners can look at to see examples of programming concepts being used to make actual programs. The complete repo is here: https://github.com/asweigart/pythonstdiogames

    The J'Accuse game source code is here: https://github.com/asweigart/PythonStdioGames/blob/master/src/jaccuse.py

    The game is similar to Homestar Runner's "Where's an egg?". Someone has kidnapped ZOPHIE THE CAT, and you travel to different locations to question suspects. Each location has a suspect and an item. Suspects either always lie or always tell the truth. You must deduce who has ZOPHIE THE CAT within 4 minutes, and you can accuse up to three people.

    EDIT: A twitch stream of me making this game will up for the next couple of days here: https://www.twitch.tv/videos/397250824

    What is the most efficient way to go about becoming a better logical thinker with programming ?

    Posted: 18 Mar 2019 02:07 AM PDT

    So I've finally managed to land a job as a developer, and I feel that I'm not ready for the tasks that may be coming my way.

    I've been programming for around 2 years, have completed plenty of YouTube and Udemy courses. However, I still lack that "logical thinking" aspect. I can't solve problems on leetcode or solve any algorithmic problem for that matter without trying so very hard.

    At times it becomes pretty demoralizing. What are the way you've managed to overcome this? Is there a must read book out there, and please don't say CLS. Do you just stare at algorithm questions all day and does it finally click or maybe you have discussions with colleagues about the problem?

    Please share your schedule, tips and anything else that you may think is useful. Thanks!

    Can I use Xcode to create applications for IOS without paying $99 to be an Apple Developer?

    Posted: 18 Mar 2019 11:31 PM PDT

    I really want to get some practice creating IOS applications. The problem is I don't want to pay $99/year since I just want to see what it's like. If I enjoy it I will gladly pay but is there any way that I could develop applications then pay $99/year to submit my applications to the app store?

    Why are arrays pointers by default? [C++]

    Posted: 18 Mar 2019 12:19 PM PDT

    In C++, arrays are pointers by default. Whenever we wish to pass an array as a parameter, we pass a pointer, and *array is the first element of that array (*arry + 1 is the second, and so on). So why is this? Why are arrays pointers by default?

    ​

    Thanks for your help.

    [OCaml] how to return an option type when using fold_left?

    Posted: 18 Mar 2019 08:15 PM PDT

    I have a function that finds the minimum positive # in a list, but I want it to return Some x (x being the smallest number) if there is, and None if there isn't (meaning no positive numbers in the list). I can't figure out how to incorporate if else expression in below. Also is using 100 as an accumulator a bad way of finding the min for comparison?

    let rec min_pos ls = List.fold_left (fun acc x -> min acc x) 100 ls

    I tried the below as well, but I'm getting type errors

    let rec min_pos ls = List.fold_left (fun acc elem -> if acc < elem then Some acc else elem) (List.hd ls) ls

    How did older programs deal with the lack of a sound FPU and IEEE standards??

    Posted: 18 Mar 2019 11:52 PM PDT

    IEEE Floating-point integers are the heart, and soul of many programs. From OpenGL to OpenCV, they create an easy, standard, tentative way for the programmer to access a slick, modern method to access decimal numbers. But they're comparatively recent. Before that, computers had external FPU cards, and before that, computers didn't even have FPUs. Von Neuman's machine didn't even have decimal numbers, thinking that "every mathematician worth a damn can keep the track of the decimal point". So how did older programs, before IEEE FPI became wave of the future, dealt with lack of a sound decimal system? Today C++'s double data type can hold up to 34 digits after the decimal point. What did they do before that?

    ​

    Thanks.

    PyQt5 keyPressEvent Help

    Posted: 18 Mar 2019 10:58 PM PDT

    Hello

    ​

    I have this music application that Im working on and I am attempting to get key press events to work. My window is setup with buttons that if clicked will play a music chord. So far that all works fine and well, but I would also like for this app to play these sounds with the use of the keyboard. Basically you press the "a" key and a chord plays, and so on. The issue is I can't get my program to recognize the key press. I have a keyPressEvent function in my file below, but when I run my program the key press does not register.

    ​

    I believe it has something to do with the QMainWindow, or possibly the focus, but I am completely new to PyQt and GUIs in general so I do not know. Does anyone know how I could change this so my program accepts key presses?

    ​

    My code is below

    What Do You Do When You Can't Focus?

    Posted: 18 Mar 2019 10:58 PM PDT

    Naturally, I think too much and therefore am prone to not paying attention, and this is a huge problem in class; I cant concentrate for more than a few minutes at a time. This leads to lots of wasted time that could be spent being more productive, or missing key points in lectures.

    Is there anybody else who's like this? How can I overcome this?

    Note) I do this even when Im with friends

Ive been looking into different entry level software development jobs and they all seem to want different things. I would like to apply to software development positions next summer and want to know what kind of things I should be learning/working on to standout to employers? Should i make an app/website? What are most employers looking for in entry level software employees nowadays?

    P.S. i have already done two highschool CS courses in java and an intro to computer programming course in uni with C.

However, I cannot find any particular robotics project online.

    How do video game / application updates work, exactly?

    Posted: 18 Mar 2019 09:07 PM PDT

    So I'm a CS Major in my fourth semester and I've always been confused by it.

    You have the original source code which is used to release a game. Let's say Smash Bros. Ultimate, as I want to get into game dev in the future. Over time there are multiple updates. A recent one added in the ability to play a new character, which obviously required a massive update to load the model, moves, etc.

    I understand the general idea, but I don't get how the execution works. Also, how would that work if you have a disk/cart and not the full game installed on your hard drive?

    Thanks for correcting my ignorance, friends.
