| Looking for help - Not For Profit project to help those forced to self-isolate due to coronavirus Posted: 15 Mar 2020 01:08 PM PDT A lot of people around the world are now being forced to self-isolate, and in most countries this is only going to get more frequent over the coming months. People in isolation struggle to get vital resources such as groceries, hygiene items, and basic medical supplies. Delivery services are becoming steadily more overloaded and booked out. For example, in central London it's now not possible to get any food delivered to your house within the next 3 weeks. For someone showing symptoms, or a vulnerable/elderly individual, waiting 3 weeks to get supplies is not an option, and neither is leaving your house. However... a lot of people have shown their willingness to help these people! There are thousands of of volunteers ready to help, but no system to match them with those that need help. We want to build a pretty simple website that allows those in need of a volunteer to enter their address and get matched with the closest volunteers in their area. I've drawn up some wireframes for the web design, but am not a developer myself so need some help on this front. This is a not for profit project, and I will not be paying for help, but will personally pay for hosting, infrastructure costs etc. Can you help in any way? Do you have any thoughts or suggestions?

| Is hackerrank hard or am I just a bad programmer? Posted: 14 Mar 2020 10:59 PM PDT I've been working through HackerRank (for like almost a year now) and recently I've been focusing on the mathematics, functional programming, and algorithms sections (I've already completed python and regex). It's really demotivating to see a medium question with a 70% success rate and not being able to complete it without extensive googling, or even not being able to solve it with that. Is HackerRank actually that hard or am I just bad? [link] [comments]  |

| Posted: 15 Mar 2020 07:37 PM PDT I have a site built in .NET Core 1.0 Preview 2. It's using the deprecated xproj file. I need to migrate the project to the lastest .NET Core 3.1. Would it be simpler to try and go through all the migration steps listed below for each new version one at a time or would it be easier to try creating a new site in 3.1 and trying to just move my code over? If the better answer is go through each migration one at a time, there are there any good walkthroughs on migrating from the preview version to .NET Core 1.0? [link] [comments]  |

| Why hasn't touch replaced the mouse Posted: 15 Mar 2020 06:18 PM PDT Is the mouse simply a better tool or is it that we are still stuck in an old way of doing things. With say a stylus you can actually get more precision for say artists and architectures. Yet it hasn't translated to touch replacing the mouse What are you thoughts on the iPad/iPad OS. Do you see this as rivaling Mac OS/Windows or will it always be less capable. Also what about the future of computing. For example do you see computing going the way of AR with hand gestures?

| What can CSS/Js do that Wordpress or any Website-building software can't Posted: 15 Mar 2020 01:04 PM PDT I know Website builders use CSS/Js so they don't differ in that sense but I often hear that you are limited while using software like that to build Websites rather than coding it urself bonus question: Is it possbile and or reccommended to use Wordpress for all the simple yet tedious parts of web development and code the rest urself? any cons to this?

| What's the quickest way to write a very simple GUI program? Posted: 15 Mar 2020 04:24 PM PDT I want to write (or find!) a program that, in theory, is very simple. Feed it HTML on stdin, it takes that HTML and displays it in a GUI window (I know rendering HTML is far from simple, but there are widgets that handle that side of things ;-)), When the window is closed, the program terminates. I need to write the program for Windows, but I have no issue with it being cross-platform, if that's easier. Also, I don't really care what language it's written in (although I'd prefer it to be something that produces a self-contained executable, to ease deployment). I feel as though this should be relatively easy, but I've not managed to find a language/library that doesn't involve investing way more time than the project warrants. (For comparison, I'd expect to write a similarly complex command line utility - finding a few standard libraries to do the heavy lifting and bolting them together - in half a day at most, even in a language I was unfamiliar with). The "obvious" thought was to use C# (as this is a Windows GUI app) but all the "beginner" examples use Visual Studio, and I really don't want to learn a new IDE for a one-off project. Most C/C++ libraries need to be built, and that often seems non-trivial. Does anyone have any good suggestions on how best to tackle this? [link] [comments]  |
| How do you define the minimal subset of functionality for a particular type of software? Posted: 15 Mar 2020 03:34 PM PDT Hi, I wonder what is the best approach to identify the minimal subset of requirements / functionality that constitute a particular type of software. For example if one wants to make a simple web server what is the approach that you would adopt in order to understand what are the minimum subset of functionality that a program should have in order for it to be regarded as a very simple web server?

| Need help solving this C exercise. Posted: 15 Mar 2020 02:39 PM PDT The exercise states: A 3000 lb vehicle travelling on a road at 100 ft/sec requires a force equal to its mass times its acceleration to stop ( F = ma). The acceleration is given by Where vi = 100 ft/sec vo = 0 ft/sec. Write a program that will calculate the retarding force needed to stop the car at distances of 10, 20, 30, 40, 50, …, 1000 ft. Display the distance value and the corresponding retarding force in tabular form. The units of force are Newtons (N). Your solution must include a user-defined function that returns the force and takes as input initial and final velocity and distance. double force(double velocityInitial, double velocityFinal, double distance, double mass); I need to solve this exercise using a for loop. I am getting 3 errors atm: 26: 'mass' is used uninitialized in this function My code right now is: #include <stdio.h> #include <stdlib.h> #include <math.h> double force(double velocityInitial, double velocityFinal, double distance, double mass); int main() { double forceFormula; int distance, mass, acceleration; forceFormula = mass * acceleration; printf("\nDistance:\t\tForce in Newtons:\n" "------------------------------------------\n"); printf("%d\t\t\t%.2lf\n", distance, forceFormula); printf("------------------------------------------\n"); return 0; } double force(double velocityInitial, double velocityFinal, double distance, double mass) { velocityInitial = 100; velocityFinal = 0; mass = 3000; double acceleration, forceFormula; for( distance = 10; distance <= 1000; distance += 10) { acceleration = ((velocityFinal * velocityFinal) - (velocityInitial * velocityInitial))/ 2 * distance; forceFormula = mass * acceleration; } return forceFormula; } [link] [comments]  |
| Getting Calls From "Ghost Numbers" Posted: 15 Mar 2020 02:16 PM PDT I'm getting calls from several ghost numbers which have a different area code (= different providers). I call them "ghost numbers" because when I try to call them back they simply don't exist and wont show up in the call history provided by my provider on their webapplication. I'm a programmer so I assume one of my friends is trolling me. I get the calls even..
Some points which may help:

| Posted: 15 Mar 2020 08:00 AM PDT I'm trying to merge 2 sorted linked lists into a new linked list in C++. New list should also be sorted. For ex: If first two lists are :- Then new list should be :- I've written a recursive approach like this :- Here, I'm trying to check if a value in 1st list is less than or equal to value in 2nd list then we will insert the value in 1st list into merged list & move forward in the 1st list. Otherwise we will stay at the current node in 1st list & move forward in 2nd list. You can find complete code here. For some reason, it is giving me Segmentation Fault / Internal Error. Don't know why. I've also written an iterative approach for merging these 2 lists. And that one is working fine. You can find iterative version here. I changed only merge function implementation in both versions. So rest of the code is same in both except merging. So I need help in figuring out that why my recursive merge function is not working.

| Python3: How to get FuncAnimation to not show the animation? Posted: 15 Mar 2020 12:30 PM PDT Hi! I have a simple simulation of a pendulum which I animated using matplotlib.animation.FuncAnimation. Since I need that animation, I saved it with ani.save(). When watching that video I have the framerate I want, but when I run the code to get a new animation, it pops up with a ridicously slow framerate. Then I have to close it and open the one I saved in .mp4. I tried removing the plt.show() but I get 'Source ID 7 was not found when attempting to remove it'. My code is(without the simulation) [link] [comments]  |

| What open-source projects can a graduate improve? Or how to earn a little bit of money? Posted: 15 Mar 2020 10:10 AM PDT Hello. As the title says, I am a graduate. I am a Computer Science Engineer. I know C# and .NET fairly alright, I know a bit about DBs, I know how to work both on an agile and waterfall projects, have a firm grasp of OOP. Are there any open source projects I can contrubute to? Or a way to earn a small amount of money without leaving home? (2 unrelated questions). I was supposed to start a job, but due to the outbreak, I am stranded sadly and feel pretty useless. [link] [comments]  |
| [JS CSS] Have one element react to input, despite another one being focused? Posted: 15 Mar 2020 10:08 AM PDT Hello! I have some input elements on the left side, and on the right side, there is a big info div that changes data depending on which input element is focused. I want to be able to have one input element focused, and at the same time be able to scroll the info element up-down with keyboard up and down. Unfortunately, input type text itself reacts to up-down keyboard input by putting the cursor to the front/back of the text. I want the left-right to work, shifting between the letters, but repurpose up-down to control the un-focused info div. Is this possible? Bonus points if I can also determine the scroll speed/amount Thank you! [link] [comments]  |
| Merging numbers using XOR and getting the outcome with the most occurrences of a number. Posted: 15 Mar 2020 08:02 AM PDT (JAVA) I have found this exercise and it fascinated me. However, I have no idea how to approach this problem. STORY So the story of this exercise is, John has created a new science called Xorchemy (based on the XOR operand). Xorchemy is a mix between Alchemy and Informatics. In Xorchemy you can merge two elements (each represented as a number between 1 and 5, including), by converting them into binary and comparing each of their numbers using the XOR operand. If for example, you would like to merge the number 2 with 1 it would go something like this. 2 = 010, 1 = 001, 0 and 0 gives us 0, 0 and 1 gives us 1, 0 and 1 again gives us 1, so the result is 011, thus 3. There are only 5 stable elements, so you can not merge elements whose output is greater than 5, or less than 1, for example, the numbers 4 and 2. INPUTS On the first line, you will get an Integer n. This represents how many elements you have, for example, 4. ( 1≤n≤1000 )On the second line, you will get n Integers, the elements, for example, 3 1 2 2. ( 1≤element≤5 ) OUTPUT You need to find a process to merge the given elements in a way that results in you having the most possible occurrences of an element that you can get and output the number of occurrences. Let's take the numbers from before, 3 1 2 2. If we were to merge 1 and 2 we would get 3 3 2, so we have 2x the element 3 and 1x the element 2. If however, we merge 3 and 1 we get 3x the element 2, which is the most an element occurred. So we would output 3. Another example is 4 5 2 3 3, where the right answer is to merge 4 and 5 (100 and 101 gives us 001), and then 1 and 2 which gives us 3, so 3x the element 3, we output 3 as that is the number of occurrences. Also in the examples, in the end, there is always only one element left, however, the assignment does not say that this must always be the case, so for example, a solution where we are left with 2x the element 3, and 4x the element 5 is a right answer as well, and the output would be 4. QUESTION How would you go about finding the right way to merge the elements? Do I even need to find the right way to merge, as the output only asks for the number of elements we will have? I do not think that the right way is to go and try all the combinations, as that would be inefficient. Any ideas. [link] [comments]  |
