• Is it possible to procedurally place objects in a non-gridded game?

  - by nickbadal

  I'd like to implement procedural world generation, but I don't want it to look gridded or blocky, where everything is obviously placed on an integer grid. I know that you can do this in gridded worlds by inputting a square's x and y into a noise function, or similar, but is it possible to generate a more natural looking object placement using procedural methods? This is in the context of an adventure game, if it matters. Edit: I guess I should have been a bit more clear in my original question, but I'm mostly wondering about the actual placement of objects in game, e.g. trees, buildings.

• Can GJK be used with the same "direction finding method" every time?

  - by the_Seppi

  In my deliberations on GJK (after watching http://mollyrocket.com/849) I came up with the idea that it ins not neccessary to use different methods for getting the new direction in the doSimplex function. E.g. if the point A is closest to the origin, the video author uses the negative position vector AO as the direction in which the next point is searched. If an edge (with A as an endpoint) is closest, he creates a normal vector to this edge, lying in the plane the edge and AO form. If a face is the feature closest to the origin, he uses even another method (which I can't recite from memory right now) However, while thinking about the implementation of GJK in my current came, I noticed that the negative direction vector of the newest simplex point would always make a good direction vector. Of course, the next vertex found by the support function could form a simplex that less likely encases the origin, but I assume it would still work. Since I'm currently experiencing problems with my (yet unfinished) implementation, I wanted to ask whether this method of forming the direction vector is usable or not.

• Useful programming languages for hardware programming

  - by Sebastian Griotberg

  I am thinking to take the next semester a course called "Digital systems architecture", and I know that we need to program micro-controllers with several programming languages such as C, C++, verilog, and VHDL. I want to be prepared to take that course, but I need to know if I need to study deeper these languages. At this moment, I have taken one course in basic Java dealing with basic methods, data types, loop structures, vectors, matrices, and GUI programing. Must I study deeper Java and then go with C, and C++? Besides, I know basic verilog and VHDL.

• Where should I put a method that returns a list of active entries of a table?

  - by darga33

  I have a class named GuestbookEntry that maps to the properties that are in the database table named "guestbook". Very simple! Originally, I had a static method named getActiveEntries() that retrieved an array of all GuestbookEntry objects. Each row in the guestbook table was an object that was added to that array. Then while learning how to properly design PHP classes, I learned some things: Static methods are not desirable. Separation of Concerns Single Responsibility Principle If the GuestbookEntry class should only be responsible for managing single guestbook entries then where should this getActiveEntries() method most properly go? Update: I am looking for an answer that complies with the SOLID acronym principles and allows for test-ability. That's why I want to stay away from static calls/standard functions. DAO, repository, ...? Please explain as though your explanation will be part of "Where to Locate FOR DUMMIES"... :-)

• Restore the Ctrl + Alt + Num Pad windows positioning commands?

  - by holocronweaver

  Using Unity in Ubuntu 12.04, the Ctrl + Alt + Num Pad combination for positioning windows has been fragmented by Ctrl + Alt + 4 (move window to left half of screen) being changed to Super + Left Arrow. A similar change moved Ctrl + Alt + 6 to Super + Right Arrow. Thus one moves windows to corners using Ctrl + Alt combos, but Super combos are needed to move to the left or right. This is more than a convenience problem since the new windows positioning provided by the super key combos seems to give different sizes than the Ctrl + Alt combos they replaced, leading to distracting gaps between windows when you combine the two methods to position three or more windows on one screen. Is there a way to restore the previous behavior so that I can use Ctrl + Alt + Num Pad for all windows positioning?

• wordpress login encryption

  - by tech

  I am running wordpress with woocommerce and theme_my_login plugins. When a user registers on my site it sends them a confirmation email and then they can click to activate account. Problem is when the user goes to login they get an error of incorrect password. If the user uses the forgot password link and resets the password then they can login without any errors. What might cause this problem? Is the password being encrypted with the wrong method? I went through the registration process and checked the string in the php users table. password in php table after registration: $P$BF/gIt6dFfBBuNx6rP41Qv3i71TUie1 password in php table after change password to same password: $P$BxpByDbNU3vr3sytTOcbzttp1tOodH1 Do Theme my login and either woocommerce or wordpress use different encryption methods?

• What's the difference between set, export and env and when should I use each?

  - by Oli

  Every so often I'll bash out a bash script and it strikes me there are a few ways of setting a variable: key=value env key=value export key=value When you're inside a script or a single command (for instance, I'll often chain a variable with a Wine launcher to set the right Wine prefix) these seem to be completely interchangeable but surely that can't be the case. What's the difference between these three methods and can you give me an example of when I would specifically want to use each one? Definitely related to What is the difference between `VAR=...` and `export VAR=...`? but I want to know how env fits into this too, and some examples showing the benefits of each would be nice too :)

• Game Development Resources? [closed]

  - by stas

  I want to make an iPhone game and I was wondering if somebody could point me to some resources. Before you rage and close this, I am not looking for just a tutorial on programming, I could just google that. I need to find a tutorial on how to actually make a game, as in how to organize your code, what type of methods to run in separate threads, how to manage these threads in a game, etc. I already know everything I need; I can write a physics engine from scratch, I can write a 3D graphics pipeline from scratch, and so on. What I cannot figure out is how to combine all of this knowledge into correctly and efficiently making a game. Obviously for this one would probably go to college, but seeing as I am still in high school, that is not an option. If anyone would know some tutorials or resources, any pointers would be appreciated.

• Is there a standard for machine-readable descriptions of RESTful services?

  - by ecmendenhall

  I've interacted with a few RESTful APIs that provided excellent documentation for humans and descriptive URIs, but none of them seem to return machine-readable descriptions of themselves. It's not too tough to write methods of my own that assemble the right paths, and many language-specific API libraries are already just wrappers around RESTful requests. But the next level of abstraction seems really useful: a library that could read in an API's own machine readable documentation and generate the wrappers automatically, perhaps with a call to some standard URI like base_url + '/documentation' Are there any standards for machine-readable API documentation? Am I doing REST wrong? I am a relatively new programmer, but this seems like a good idea.

• How to learn to translate real world problems to code?

  - by StudioWorks

  I'm kind of a beginner to Java and OOP and I didn't quite get the whole concept of seeing a real world problem and translating it to classes and code. For example, I was reading a book on UML and at the beginning the author takes the example of a tic tac toe game and says: "In this example, it's natural to see three classes: Board, Player and Position." Then, he creates the methods in each class and explains how they relate. What I can't understand is how he thought all this. So, where should I start to learn how to see a real world problem and then "translate" it into code?

• How can I generate Sudoku puzzles?

  - by user223150

  I'm trying to make a Sudoku puzzle generator. It's a lot harder than I expected and the more I get into it, the harder it gets! My current approach is to split the problem into 2 steps: Generate a complete (solved) Sudoku puzzle. Remove numbers until it's solveable and has only 1 solution. In step 1, since I'm using a brute force methods, I'm facing some run time issues. Is there an optimal way of filling in a complete Sudoku puzzle? In step 2, what kind of algorithm should I use to "puzzlize" a solved sudoku?

• Any pre-rolled System.IO abstraction libraries out there for Unit Testing?

  - by Binary Worrier

  To test methods that use the file system we need to basically put System.IO behind a set of interfaces that we can then mock, I do this with a DiskIO class and interface. As my DiskIO code gets larger (and the grumblings from the we're unconvinced about this TDD thing crowd here in work get louder), I went looking for a comprehensive open source library that already does this and found . . . nothing. I may be looking in the wrong place or have approached this problem in completely the wrong way. I can't be the only idiot in this position, do these libraries exist, if so where are they? Any you've used and would recommend? Thanks P.S. I'm happy with my current approach i.e. starting with what we need, and adding only when the need arises. Unfortunately the we're unconvinced about this TDD thing crowd remain unconvinced, and think that I can't be right.

• Is there a way I can verify my Google Analytics custom report?

  - by SnowboardBruin

  I want to track scrolling on my website since it's a long page (rather than multiple pages). I saw several different methods, with and without an underscore for trackEvent, with and without spaces between commas <script> ... ... ... ga('create', 'UA-45440410-1', 'example.com'); ga('send', 'pageview'); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 100, true]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 75, false]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 50, false]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 25, false]); </script> It takes a day for counts to load with Google Analytics, otherwise I would just tweak and test right now.

• Set modified date = created date or null on record creation?

  - by User

  I've been following the convention of adding created and modified columns to most of my database tables. I also have been leaving the modified column as null on record creation and only setting a value on actual modification. The other alternative is to set the modified date to be equal to created date on record creation. I've been doing it the former way but I recent ran into one con which is seriously making me think of switching. I needed to set a database cache dependency to find out if any existing data has been changed or new data added. Instead of being able to do the following: SELECT MAX(modified) FROM customer I have to do this: SELECT GREATEST(MAX(created), MAX(modified)) FROM customer The negative being that it's a more complicated query and slower. Another thing is in file systems I believe they usually use the second convention of setting modified date = created date on creation. What are the pros and cons of the different methods? That is, what are the issues to consider?

• Instantiating Interfaces in C#?

  - by RealityDysfunction

  I am reading/learning about interfaces in C# at the moment, and thus far I managed to understand how it differs from an abstract class. In the book I am reading the author explains that interfaces are the ultimate abstract class and that it simply sets the standard of certain methods the inheriting class will have, but then provides the following example... static void Main(string[] args) { ... Circle c = new Circle("Lisa"); IPointy itPt = null; try { itPt = (IPointy)c; Console.WriteLine.(itPt.Points); } catch (InvalidCastException e) { Console.WriteLine(e.Message); } ... } The line that absolutely throws me off is the "IPointy itfPt=null;" did he just declare an interface??? I thought interfaces are abstract and can only be inherited? What kind of sorcery is going on here? Thanks for any help, I

• Is it correct to refer to a performing programming assignments as a "computer labs"?

  - by Nick Rosencrantz

  Can we say that developing an algorithm is a "laboration"? Are these "labs"? At engineering performing an exercise or an assignement is refered to as "labs" but are those "labs" when in fact it is mainly software problem solving pretty much like numeric methods in math which are not "labs". When studying engineering such as electrical engineering or physics you might do a "laser lab" or a "chemical laboration" if you study chemical engineering for instance. How do you define "lab"? Just performing something experimental? This is sort of double meaning also the physical environment at universities which we call "computer labs" that in fact are just rooms with computers.

• How to implement proper identification and session managent on json post requests?

  - by IBr

  I have some minor messaging connection to server from website via json requests. I have single endpoint which distributes requests according to identification data. I am using asynchronous server and handle data when it comes. Now I am thinking about extending requests with some kind of session. What is the best way to define session? Get cookie when registered and use token as long as session runs with each request? Should I implement timeout for token? Is there alternative methods? Can I cache tokens to same origin requests? What could I use on client side (Web browser)? How about safety? What techniques I should use to throw away requests with malformed data, to big data, without choking server down? Should I worry?

• How To Sideload Modern Apps on Windows 8

  - by Chris Hoffman

  The average Windows 8 user can only download apps that Microsoft has approved from the Windows Store. Windows 8 offers two ways to sideload unapproved apps, which are intended for developers and businesses with internal apps. These methods cannot be used by the average geek to install unapproved apps from the web. Windows 8’s new interface takes the Apple iOS approach of forbidding unapproved software, not the Android approach of allowing all users to enable sideloading. Note: This only applies to Modern apps in the new Windows 8 interface, not on the desktop. Windows desktop applications can be installed normally. However, you can’t install any desktop applications on devices running Windows RT. Why Does 64-Bit Windows Need a Separate “Program Files (x86)” Folder?

• Tile transitions - external vs internal

  - by omgnoseat

  I've been looking at a couple of games and noticed that the transitions between tiles are handled somewhat different. I was wondering which methods are to be used in different situations and why. I'm currently using internal edges in a top-down game, and it's working out so far. But I don't want to run into problems later on, and have to redo the whole tileset. I noticed that platforming games mostly use the internal edges, and top-down games mostly use external and hybrid transitions. I can see how these tiles are used to create "depth" in top-down games, where the player apears to be standing in front of a wall for example. But it seems unlikely that such a small feature decides the entire method for tile transitions. You could always alter the bounding box to create the same effect.

• Developing gnome shell extensions with eclipse as a IDE

  - by GAP

  I would like to know whether any body has used Eclipse JavaScript support for developing gnome-exensions. Actually aiming here for the context support which is available in eclipse. And i though if i could add all the java scripts that a extension is inheriting (base scrips) in to a user library, then i could included it as a dependency in my extension project. Have any once done this already ? Does all the methods that are used in a exentions exist in the base scripts ? In what directories does the base scripts exist ? So far i tried adding the scripts in the following directory but still i have error when i try to look at the journal gnome extension code. /usr/share/gnome-shell/js /usr/share/gjs-1.0 Thanks

• How can you procedurally place objects in a non-gridded game?

  This is a follow-up question to this question. I mistakenly worded the question, but got a good answer before I could correct myself, so I didn't want to delete it. Sorry! Now that I know that it is possible, I'd like to implement procedural world generation, but I don't want it to look gridded or blocky, where everything is obviously placed on an integer grid. I know that you can do this in gridded worlds by inputting a square's x and y into a noise function, or similar, but how can I generate a more natural looking object placement using procedural methods?

• Domain Model and Querying

  - by Tyrsius

  I am new to DDD, having worked only in Transaction-Script apps with an anemic model, or just Big Balls of Mud, so please forgive any terminology I abuse. I am trying to understand the proper separation between the domain model and the repository. What is the proper way to construct a domain object that is coming from a database, assuming the (incredibly simplified) need to query for objects by status (returns enumerable), or by ID. Should a factory be building the objects, exposing methods for GetByStatus() and GetByID(), using a DIed repository? Should a repository be called directly, knowing how to build a domain model from the DTO? Should the domain model have a constructor for get by ID, using a DIed repoistory to load the initial state, using some other (?) method for the list? I am not really sure what the best way would be, and this question has an answer advocating each one (these are certainly mutuallu exclusive).

• How much data validation is too much? [closed]

  Possible Duplicate: Data input validation - Where? How much? I'm a new PHP developer and am into Powershell quite a bit but this question is language agnostic. I've been questioning my code quite a bit lately thinking about how many nets I should setup to catch exceptions, verify results, etc. I realize that I could go crazy trying to verify each and every line of code but at the same time I want the code as resilient as possible. I'm not talking about user input but verifying output from methods. Is there some standard or rule of thumb to go by when deciding when and where to do data validation?
