• Are all languages basically the same?

  - by Anirudh

  Recently, i had to understand the design of a small program written in a language i had no idea about (ABAP, if you must know). I could figure it out without too much difficulty. I realize that mastering a new language is a completely different ball game, but purely understanding the intent of code (specifically production standard code, which is not necessarily complex) in any language is straight forward, if you already know a couple of languages (preferably one procedural/OO and one functional). Is this generally true? Are all programming languages made up of similar constructs like loops, conditional statements and message passing between functions? Are there non-esoteric languages that a typical Java/Ruby/Haskell programmer would not be able to make sense of? Do all languages have a common origin?

• When do you use float and when do you use double

  - by Jakub Zaverka

  Frequently in my programming experience I need to make a decision whether I should use float or double for my real numbers. Sometimes I go for float, sometimes I go for double, but really this feels more subjective. If I would be confronted to defend my decision, I would probably not give sound reasons. When do you use float and when do you use double? Do you always use double, only when memory constraints are present you go for float? Or you use always float unless the precision requirement requires you to use double? Are there some substantial differences regarding computational complexity of basic arithemtics between float and double? What are the pros and cons of using float or double? And have you even used long double?

• Where can I find simple, but well-written programs to learn from?

  - by user828584

  I've tried a few times to look at the source code for various things from github or other sites, in javascript, C#, PHP, etc. I'm never able to understand the programs as a whole though. I can sort of piece together what a specific snippet of code does, but I quickly lose the context of what I'm looking at and how it fits in. I want to be able to improve, but everything I've tried learning from so far has been too big. Where can I find well-written, but not very complex source code to look at? edit: Sorry, to be more specific, I'm hoping for javascript/php/C#.

• What are some good resources for learning about file systems? [closed]

  - by Daniel

  I'd like to learn about file system design at a very detailed level. I'm currently in a graduate level operating systems course, and we're currently going over file systems. We mostly discuss papers and such, but our semester long project is to implement a log-structured file system using fuse and a virtual disk. Are there any good books that focus heavily on file system design and implementation? I have some conceptual clouding on things that seem very basic such as "when we say that an inode has pointers to blocks, do we mean anything besides the inode keeping track of block numbers? Is there any other format for 'disk pointers'?" I'm actually looking at file system design to start my career, so I'm probably going to try to implement a more traditional file system with fuse and our virtual disk format after this course is over.

• Simpler alternative to AngelScript

  - by Vee

  I want to give players the ability to create and share bullet patterns for a shoot'em up. The pattern scripts should have all the common programming stuff like loops, if/else, variables, and so on. But in the end, I just want them to call a "spawn bullet at X, Y with Z angle and A speed" in the C++ game. To spawn a circle of bullets, the user should only have to write a script with a for loop that goes from 0 to 360 and calls the spawn bullet function on every iteration. I tried integrating AngelScript, but I am getting nowhere - it looks way to complex for a simple task like this one. Is there an easy to integrate library that can solve my problem? Thanks.

• What options are there for integrating with payment gateways?

  - by Rowland Shaw

  It seems that there are only two types of payment gateway service out there at the moment; Either that the entire cart logic is handled offsite (with something like Paypal's Standard option) or the other option being that you need to go through the certification for handling credit card numbers and doing pretty much everything yourself. Ideally, for the project I'm working on, I'm after a bit of middle ground such that I can handle the cart on-site, and only pass over to a payment gateway (with an order amount, billing & delivery details, and order ref) for them to handle the card details, before passing back. I'm sure that I've used e-commerce sites using this pattern before, but I cannot find any payment providers out there that offer this sort of option, so are there any? The only over requirement we have at present is that it must accept orders in Sterling.

• Microsoft Money alternative?

  - by torbengb

  I'm looking for something to replace my MS Money 2004 application. I've tried KMyMoney which seems pretty simple (that's good!) but it can't import the OFC files I get from my bank, so I would have to enter everything manually = not good. I've tried GnuCash which does import OFC files but I can't wrap my mind around this double-entry philosophy. It may be good for accounting but not for home use. I've tried to make MS Money run in Wine with some success but it was hard to make it work and I'd have to re-do that on my new machine. This is still a useful alternative for me though... Is there a similar tool that can import OFC files and that doesn't do double-entry accounting? Tax capability is not needed for me, I only do after-tax numbers. Some nice dashboard views (upcoming bills, future cash flow, total net worth) and some graphs would be a definite bonus!

• Attaining credit card data

  - by Adam

  I've read the many posts on this site that say we are not allowed to store cc numbers if we are not pci-compliant. But, I'm wondering if it is possible to send a CC number through a form to an email address? Would that be still infringing on the standards? The reason I ask is that a local business owner wants to retrieve a number through a form on his website, so he can manually enter the cc info on his end. I'm assuming the only way to properly get a credit card number is to setup a merchant account? What's the best way to get a cc number without calling the actual customer? I'm thinking email is a bad idea as well.

• Organazing ASP.Net Single Page Application with Nancy

  - by OnesimusUnbound

  As a personal project, I'm creating a single page, asp.net web application using Nancy to provide RESTful services to the single page. Due to the complexity of the single page, particularly the JavaScripts used, I've think creating a dedicated project for the client side of web development and another for service side will organize and simplify the development. solution | +-- web / client side (single html page, js, css) | - contains asp.net project, and nancy library | to host the modules in application ptoject folder | +-- application / service (nancy modules, bootstrap for other layer) | . . . and other layers (three teir, domain driven, etc) . Is this a good way of organizing a complex single page application? Am I over-engineering the web app, incurring too much complexity?

• What is a good way to measure game virality?

  - by Chris Garrett

  I have added some social features to an iPhone game (Lexitect if you're curious), such as email, Twitter, and Facebook integration for sharing high scores. Along with these features, I am measuring how many times users make it to each step. The goal of these features are to make the game more viral, and I am trying to get to a measure of game virality. I would think that a game virality metric would produce a number based on 1.0, where 1.0 = zero viral growth, and 1.01 would represent 1% viral growth over some unit of time. How is virality normally measured, and in what units? How is time capped on the metric? i.e. if I gave each player a year to determine how many recommendations they make, I wouldn't get any real numbers for a year from the time I start tracking it. Are there any standards for tracking virality in a meaningful way?

• From where does the game engines add location of an object?

  - by Player

  I have started making my first game( a pong game )with ruby (Gosu). I'm trying to detect the collision of two images using their location by comparing the location of the object (a ball) to another one(a player). For example: if (@player.x - @ball.x).abs <=184 && (@player.y - @ball.y).abs <= 40 @ball.vx = [email protected] @ball.vy = [email protected] But my problem is that with these numbers, the ball collides near the player sometimes, even though the dimensions of the player are correct. So my question is from where does the x values start to count? Is it from the center of gravity of the image or from the beginning of the image? (i.e When you add the image on a specific x,y,z what are these values compared to the image?

• Analysing Group & Individual Member Performance -RUP

  - by user23871

  I am writing a report which requires the analysis of performance of each individual team member. This is for a software development project developed using the Unified Process (UP). I was just wondering if there are any existing group & individual appraisal metrics used so I don't have to reinvent the wheel... EDIT This is by no means correct but something like: Individual Contribution (IC) = time spent (individual) / time spent (total) = Performance = ? (should use individual contribution (IC) combined with something to gain a measure of overall performance).... Maybe I am talking complete hash and I know generally its really difficult to analyse performance with numbers but any mathematicians out there that can lend a hand or know a somewhat more accurate method of analysing performance than arbitrary marking (e.g. 8 out 10)

• Is your company thinking of transitioning from java to another technology?

  - by Augusto

  As every Java developer knows, Oracle bought Sun and the future of java looks quite unclear, specially since Oracle wants to monetize the JVM. Java as a language has also been stale in the last few years, the non-inclusion of closures is one example (which might be included in java 1.8) At the same time, some new technologies such as Ruby, Scala and Groovy are being used to deliver complex sites. I'm wondering if there are companies or organizations which are talking, doing spikes or starting to use a different technology, with the idea to stop using java for green field projects, in the same way that 15 years ago companies migrated form C++, perl and other technologies to Java. I'm also interested to know what are the impressions of this happening, for example: planning to migrate to a different technology in 2 years. To be clear, I'm not asking which technology is better. I'm asking if your organization is thinking to leave Java for another technology.

• Checking whether a specific key was pressed in enchantJS

  - by MxyL

  I am using enchantJS and would like to use the letters and numbers as well as numpad on a keyboard to do different things (eg: hotkeys). From this page http://users.csc.calpoly.edu/~foaad/enchant/guide/playerInput.html By default, enchant.js provides input listeners for six buttons: UP, DOWN, LEFT, RIGHT, A, and B. By default, the directions are bound to the arrow keys. Any of the six buttons may also be bound to any key with an ASCII value. We’ll address that later. So enchant provides the ability to bind keys to different input such as up, down, left, right...but how can I simply check whether the D or X key was pressed, and if so, perform certain actions based on that event?

• Standard -server to server- and -browser to server- authentication method

  - by jeruki

  I have server with some resources; until now all these resources were requested through a browser by a human user, and the authentication was made with an username/password method, that generates a cookie with a token (to have the session open for some time). Right now the system requires that other servers make GET requests to this resource server but they have to authenticate to get them. We have been using a list of authorized IPs but having two authentication methods makes the code more complex. My questions are: Is there any standard method or pattern to authenticate human users and servers using the same code? If there is not, are the methods I'm using now the right ones or is there a better / more standard way to accomplish what I need? Thanks in advance for any suggestion.

• How to change keyboard layout?

  - by swedishhh

  I'm on ubuntu 12.04. Recently I bought a cheap apple style bluetooth keyboard. It pairs OK. I paired it with the current 102 key still attached. Anyway I noticed that the character mapping is incorrect. Most keys do not type anything - some keys on the right (k, l, ;') etc give numbers, but that's about it. So I rebooted, with 102 kbd unattached, and the bluetooth keyboard on, ready to connect. After boot at the login screen, the bluetooth keyboard had paired. I typed my password, and it logged in fine!! However after the user login was complete it reverted to the broken behaviour. A glance at the layout chart shows ubuntu thinks I still have the 102 layout, even though it remained disconnected. Any ideas? Thanks, Dave

• Writing to a structured buffer with a compute shader (D3D11)

  - by Vertexwahn

  I have some problems writing to a structured buffer. First I create a structured buffer that is filled with float values beginning from 0 to 99. Afterwards a copy the structured buffer to a CPU accessible buffer is made to print the content of the structured buffer to the console. The output is as expected (Numbers 0 to 99 appear on the console). Afterwards I use a compute shader that should change the contents of the structured buffer: RWStructuredBuffer<float> Result : register( u0 ); [numthreads(1, 1, 1)] void CS_main( uint3 GroupId : SV_GroupID ) { Result[GroupId.x] = GroupId.x * 10; } But the compute shader does not change the contents of the structured buffer. The source code can be found here (main.cpp): https://bitbucket.org/Vertexwahn/cmakedemos/src/4abb067afd5781b87a553c4c720956668adca22a/D3D11ComputeShader/src/main.cpp?at=default FillCS.hlsl: https://bitbucket.org/Vertexwahn/cmakedemos/src/4abb067afd5781b87a553c4c720956668adca22a/D3D11ComputeShader/src/FillCS.hlsl?at=default

• Methodology for Documenting Existing Code Base

  - by George Stocker

  I work as part of a team on an existing application that has no inline documentation, nor does it have technical documentation. As I've been working on various bug reports on the application, I've written a sort of breadcrumb trail for myself - bug numbers in various places so that the next developer can refer to that bug number to see what was going on. My question is thus: What is the most effecient method for documenting this code? Should I document as I touch the area (the virus method, if you will), or should I document from each section on its own, and not follow paths that branch out into other areas of the application? Should I insert inline comments where none previously existed (with the fear that I may end up incorrectly identifying what the code does)? What method would you use to accurately and quickly document a rather large application that has no existing inline documentation, nor inline references to external documentation?

• Formula for three competing heroes, each has one they can beat and one they're beaten by

  - by Georgiadis Abraam

  I am trying to design a game for a project I have, The main idea is: 3 Types of heroes 3 Stats per hero There are no levels involved so the differences must be located on stats. Fight logic - The logic of fight is that type1hero has good chances winning type2hero, type2hero has good chances type3hero and type3hero has good chances winning type1hero. For over a week I am trying to find a stats based formula that will allow me to fix this but I can't, I was meddling with numbers yesterday and it was decent but I can't extract the formula out of it. Could you please guide me or give me hints on how should I start creating formulas on a Non lvl game that fulfills the fight logic?

• How are minimum system requirements determined?

  - by Michael McGowan

  We've all seen countless examples of software that ships with "minimum system requirements" like the following: Windows XP/Vista/7 1GB RAM 200 MB Storage How are these generally determined? Obviously sometimes there are specific constraints (if the program takes 200 MB on disk then that is a hard requirement). Aside from those situations, many times for things like RAM or processor it turns out that more/faster is better with no hard constraint. How are these determined? Do developers just make up numbers that seem reasonable? Does QA go through some rigorous process testing various requirements until they find the lowest settings with acceptable performance? My instinct says it should be the latter but is often the former in practice.

• Real performance of node.js

  - by uther.lightbringer

  I've got a question concerning node.js performance. There is quite lot of "benchmarks" and a lot of fuss about great performance of node.js. But how does it stand in real world? Not just process empty request at high speed. If someone could try to compare this scenario: Java (or equivalent) server running an application with complex business logic between receiving request and sending response. How would node.js deal with it? If there was need for a lot of JavaScript processing on server side, is node.js really so fast that it can execute JavaScript, and stand a chance against more heavyveight competitors?
