    Do you think that Agile leads to bad code?

    Posted: 18 Apr 2018 05:11 PM PDT

    I'm not a developer by training, but I am by trade. For me, as a mostly self-trained dev, getting into a corporate position was quite intimidating. I always felt like my code was rough, unrefined, and badly planned. I always had this idea that corporations adhere to some strict standards and methods and I'd be exposed as a hack. When I started working in the industry, to me Agile was just a buzz word that I had a vague idea about. But I felt like it was something handy to learn, so I took up a position at a company that practices Agile.

    Boy was I in for a surprise. Suddenly the shitty code that I wrote at school seemed like the epitome of elegance. I was baffled and confused at just how shitty the whole codebase was. I've worked with large (open source) codebases before, so for me the only point of reference was nicely structured and well documented OS libs. What I saw in practice was a total mess, full of kludges and without any sense of logic. And absolutely zero documentation or planning. Plus, pulling was like a russian roulette, because you never know if the code is still going to work afterwards, or if someone introduced a core during lunchtime.

    Now before taking this job I had several interviews, all with companies that used Agile. I still do interviews sometimes if I find something interesting. Recently I had an interview, and it got me even more confused. I was asked about UML diagrams, the stages of software development, and a bunch of other stuff that I was so nervous about before going in the industry, since I had no fucking clue about any of it. It was like no other interview I had before, and I was wondering: how come I actually get to do my job without dealing with any of it? So I went to coursera and started an Agile course to understand. And lo and behold, all the stuff I was asked about was covered in the introduction, as the way software development used to be like, and why it's such a shitty way to go. And it made total sense to me, apparently the way I coded all my life wasn't just shitty, it was agile.

    Then the lectures went on to the principles of Agile. Like how code should take priority over everything else, including planning and documentation. And it clicked with me to a degree, since I was used to code without much planning and only ever documented stuff for myself. But fucking hell, the way I've witnessed it applied was just too much.

    So I'm wondering, is this normal? Is it Agile that leads to shit code? Or is there something that I can do within my own team to make our lives better in some way? The thing is, my teammates and our management are all very open about this subject. We always try to think of ways to improve our workflow, but our efforts fall short somehow. Is there even something like a right way to Agile, or is this it?

    Looking for help on how to improve my new dev team environment

    Posted: 18 Apr 2018 06:57 PM PDT

    Recently, I joined a development team that seems to be stuck somewhere 20 years ago.

    The environment:

    • PHP
    • No framework
    • No MVC-like structure
    • Code repetition accross multiple pages
    • Mixed HTML, PHP and SQL on .PHP pages
    • Maintenance team doesn't approve use of front end libraries such as Bootstrap, saying that the code is "too hard to maintain and understand"
    • Maintenance team believes PHP using classes doesn't have anything to improve over the structural style
    • They are too afraid to change in any way due to management

    I'm looking for a way to try to improve this environment with the minimal impact. Already tried to build a minimal MVC framework structure, but it was deemed hard (due to 'Routing' concept in specific).

    Can anyone offer directions on how to do minimal improvements in this scenario, to try to improve at least the code repetition?

    (any other tip on how to improve would be awesome to be honest)

    PS: I can't leave the job! And not looking for job advices, just on how to suggest and make improvements on the code there.

    C - are heap arrays always set to 0

    Posted: 18 Apr 2018 09:53 PM PDT

    So I just wrote a program to print all elements of a heap-allocated array and it turns out that they were all 0, so my question is: can I take this for granted and not even bothering initializing the array?

    If not, what's the proper way to set all elements of an array to a specific value?

    I tried using the memset() function here: 

    int *array = (int *)(malloc(sizeof(int) * n)); int i; memset(array, 1, sizeof(array)* n) for (i = 0; i < n; i++) printf("%d\n", array[i]);

    but for some odd reason i'm no getting 1's but rather, 33686018. Why is that?

    Automating applications, implementing predictive analytics.

    Posted: 18 Apr 2018 03:03 PM PDT

    I'll try to be brief: I don't have alot of experience with coding (basic python, R and excel, for stats) and I wanted to see if a. what I would like to do is possible, and b. where I could go to learn more.

    First question. I recently started working for a new company that helps individuals that don't qualify for traditional sources of funding find funds to help start their business. One avenue we use is to connect them with different credit card lenders. We typically with have them go to 5-10 different banks. What I would like to do is have them fill out one form on our website, that could then (in the background) take the information they input in that form, go to the different websites of the banks, and fill out the forms automatically. I have looked into possibly using headless chrome with selenium, casperjs, or other programs, however I'm not sure if that is the correct approach, or if there would be a better option? Also, by doing this, would this throw up a red flag on the bank applications website? Let me know if there is any other info that you need!

    Second question. I have worked with statistics a bit, but have never had to take the model i've built, and put it into a server. How would I go about implementing my model so when knew information comes in, it will be filtered through the algorithm? I have access to SAS spss statistics, and SPSS modeler.

    Thank you in advance for you help!

    Regex to find Nth Occurrence of Character per line

    Posted: 18 Apr 2018 08:30 PM PDT

    I am looking for a regex that will search a line of a text file in NP++ and return the nth occurrence of a character, in my case ";". I will then replace the nth occurrence of a character with a tab using $1\t

    I am doing this because I need the data to get into excel, and excel can only handle 32,767 characters per cell. If i paste as is, excel will cut off the text at 32,767 and then start the rest on a new row. If i do this Find/Replace it will paste across.

    I used the Regex of (.{32000}) to split the lines at 32,000 characters, but it was splitting email addresses down the middle.

    Any help would be greatly appreciated.

    How to write C Program to read .dat file?

    Posted: 18 Apr 2018 08:20 PM PDT

    I have an assignment in C Programming that I'm having a really hard time grasping. The assignment is as follows:

    "The sample program as shown below reads numbers from the data file "Data.txt", and performs input data validation.

    // A sample program demonstrating reading data from a text file, with data validation // file.cpp : Defines the entry point for the console application. #include "stdafx.h" #include <stdio.h> #define ERR1 "\aPrice incorrect. Re-enter both fields.\n" #define ERR2 "\aAmount incorrect. Re-enter.\n" void flushLine(FILE* file) { char c; while (c = fgetc(file) != '\n') printf("c: %c\t", c); } int main() { FILE *inputFile; inputFile = fopen("Data.txt", "r"); //fopen() returns NULL if the file opening fails int result = -1; int price = -1; int amount = -1; do { result = -1; price = -1; amount = -1; //printf("\nEnter amount and price: "); result = fscanf(inputFile, "%d %d", &amount, &price); if (result == EOF) break; printf("The number of successful scanned data = %d.\n", result); printf("amount: %d, price: %d, total = %d\n", amount, price, price*amount); if (result != 2) { //FLUSH; flushLine(inputFile); if (result == 1) printf(ERR1); else printf(ERR2); } } while (result != EOF); return 0; }

    Test the program by using a different data file, called "Sample.dat" with the following content."

    2 0 3 a 4 5 A 4 5 5 8 9

    The assignment sounds so simple. Yet, I have no idea where to start because I don't understand the question. Someone please help!

    How to dim/turn off MacBook Pro keyboard backlight with AppleScript?

    Posted: 18 Apr 2018 01:53 PM PDT

    I would like to add a section to this AppleScript I'm working on that when run, it will either turn off my keyboard backlight, or dim it all the way down. I have tried getting System Events to type a key code, but unfortunately I could not find what key code presses the button which turns down my keyboard backlight brightness. Any ideas guys? I'm using a 13" 2015 MacBook Pro with macOS High Sierra (obviously no touch bar). Thanks!!

    Is the internet old technology?

    Posted: 18 Apr 2018 03:04 PM PDT

    I'm not sure if this is the appropriate place for my question, but I saw this interview with Tim Wu (https://www.youtube.com/watch?v=N5nuCtOIQN4 - at 17:25) and he says the internet is based on old technology and suggests there could be a successor it. He says it's an old protocol written in the 70's. I have no idea what he means, so can someone explain?

    Thanks for any responses!

    How to get this canvas photo to display properly?

    Posted: 18 Apr 2018 04:28 PM PDT

    I am trying to add an image to a canvas object, but for the life of me I cannot figure out how to get it to display properly. It shows the canvas object (a circle), but not the image.

    Here is my canvas HTML:

     <canvas id="leaf" width="60" height="60" style="border:1px solid #d3d3d3;"></canvas>

    Below is the relevant JS:

    let canvas = <HTMLCanvasElement>document.getElementById('leaf'); let context = canvas.getContext('2d'); let imageObj = new Image(); imageObj.onload = function() { context.save(); context.beginPath(); context.arc(30, 30, 28, 0, 2 * Math.PI); context.clip(); context.drawImage(imageObj, 0, 0); }; imageObj.src = 'http://www.html5canvastutorials.com/demos/assets/darth-vader.jpg'; context.restore(); context.beginPath(); context.arc(30, 30, 28, 0, 2 * Math.PI); context.drawImage(imageObj, 0, 0); context.strokeStyle = 'red'; context.stroke(); console.log(canvas.toDataURL()); return canvas.toDataURL();

    But instead of showing the image within the circle, it just displays the circle, without the image...

    How to move from hacking on Zapier to on-demand scripting with Ruby?

    Posted: 18 Apr 2018 03:37 PM PDT

    I work a lot on basic business integrations for friends as side projects. Those are very niche and irregular tasks I'm solving mostly with static websites, forms and integrations with email, google sheets, storage backend.

    I'm using tools like Zapier and SaaS form backends to stitch it all together, but free tiers always lack that one most important feature which makes everything either complicated to walk-around, or expensive (usually I only need paid versions for one specific function, but I have to pay fixed $20/m for everything included)

    I have some programming experience (Ruby and Ruby on Rails), but I think RoR app is a fixed monthly cost overkill. I was wondering about cloud computing / serverless / whatever it's called today to host multiple Ruby scripts I can use on demand and pay pennies for execution.

    I'm aware of three platforms: AWS Lambda, Google Firebase and Microsoft Azure. Which one is the most friendly for beginners? I read that they all support Ruby - is it limited or everything is working well? Or maybe there is something else I should try?

    Thanks

    I have an input when called returns an HTMLElement because Value isn't in the setup of the element using ".value" returns nothing. however if you expand the above in lets say the firefox inspector. you can clearly see it has a value. how do I get that value?

    Repetetive task elimination How to?

    Posted: 18 Apr 2018 03:31 AM PDT

    I am working with some very old legacy code from 2000's(VB.Net) And every function/sub/method call needs to be logged. Basically I need to add this line "ProtokolliereVerbose(System.Reflection.MethodInfo.GetCurrentMethod().Name)" at the begining of every single method/function/sub/etc in the whole solution. Which contains 100s of classes and 1000s of methods. Some classes are even 7k lines long.. Using VisualStudio 2015 with ReSharper, and can't use RegEx since I am not replacing anything, or am I missing something?

    What language would I use...

    Posted: 18 Apr 2018 09:31 AM PDT

    I would like to create a simple calculator type app (for iOS and Android) where the user inputs specific numbers, the app runs the formula and the user gets results. It seems fairly simple in my head, but I know nothing is ever that easy.

    What language would I have to use for something like this? How should I be structuring my thinking around development? What are some good resources for app development?

    Editing An Image Template On Backend

    Posted: 18 Apr 2018 02:34 AM PDT

    I'm a mobile application developer. I'm trying to make a application where users will be able to customise an image template to make the custom design for their needs. I have never played with image processing before. Don't know how to do it. I guess there's no way to edit the value of a psd file in backend. So are there any other file types which can be edited. I have seen some logo maker apps. Where we type a business name and it shows us different designs with that text. What tech do they use to get that result. Need Help :(

    Read in a 1000 x 1000 csv grid, of values 0 to 100, and determine the best value 10x10 grids.

    Posted: 18 Apr 2018 08:16 AM PDT

    So I'm not asking for an outright solution, this isn't a do it for me request, but more so that I honestly don't know where to start with this. Most of my programming experience lies with mobile development, not data handling / mining.

    So I ask, what are some good languages to use for this sort of thing? An outline of how I would go about achieving this would be very helpful!

     

    So the idea in a little more detail; There is a 1000 x 1000 csv grid. Each cell in the grid has a value from 0 to 100. The objective is to find the most 'prosperous' 10 x 10 pieces on the grid.

    All weird or wonderful or optimal or just outright silly ideas are welcome!
