• Can anyone recommend a good SMS gateway for PHP?

  - by Nick

  I'm looking for an SMS gateway that has the following criteria: Supports sending from short codes Opt-in capabilities for end-user (will require user to opt in before sending message) Has a clean API, preferably an XML/ REST API, although SOAP is fine The cheaper the better Honestly, I keep searching and searching all permutations of "SMS Gateway API" etc... on Google and I can't find any great services that can support all of these criteria. There are a lot of really SEO optimized sites and I can't tell which of them are legit. I'm looking for something that will be easy and quick to implement, and none of my colleagues have any recommendations. What APIs have you used (preferably with PHP) that have gotten this job done? Which services have been the most pleasant to deal with, both technically and support-wise? Update: Will be sending primarily (probably solely) in the US.

• How to program a cutting tool for 3D model in game

  - by Jesse S

  I'm looking for a resource to figure out how to program a function to cut a 3d model in game. Example: Enemy/NPC is sliced into 2 pieces with a sword. His body is not hollow, you can see bloody texture where normally a 'polygon hole' would be. The first step is to actually 'cut/slice' the model, then add in polygons to fill the hole in the model. I know this can be done in 3D modelling software, but I'm not sure how to go about doing this in a game, code-wise. I do not wish to use 'pre cut-up" models, the code will determine where the cut is. Any pointers in the right direction would be greatly appreciated.

• Do you need expensive servers and fancy hosting in order to make a multiplayer game?

  - by ThePlan

  I've finished working on an RPG and it would seem so much more fun to make it multiplayer. SFML has a networking feature, I figured it's possible but then again, never in my life have I even tried something basic about networking, in fact my knowledge of it is very limited. What would it take to make a multiplayer game resource-wise? I'm not talking about an MMO, more like a co-op type of game. Do I need mountains of cash to pay for hosting and servers and many many things to make one?

• How do I know if I've gone too far with processing things in a game?

  - by ThePlan

  A common programming quote I see every day is: Premature optimization is the root of all evil! I admit I'm one of those guys that like to do premature optimization in a pretty obssessive manner but that's probably because I'm not aware how powerful modern processors are. I can think of lots of sollutions for a problem, but all of them are tough on the memory side, and I keep thinking "This will hurt me more in the future when I'll have to re-do it because it's bad performance-wise." How do you know when the code you are thinking of is going too far and is not a case of premature optimization? How much can your game handle at a time before performance becomes a problem?

• Scrum in a consulting environment?

  - by Darla

  Is it possible to introduce scrum to a consulting environment? On any given week I might belong to 4 different teams, each with a different PM, BA and dev team (I am a designer). It doesn't seem feasible, time wise, to be able to be part of that many teams/projects as there would need to be daily stand-ups for each, sprint reviews, etc. I should add these projects are not necessarily software, but mainly ecommerce web projects. Can someone who has done this speak to how you approach it?

• A look at an example of anti-spam algorithm

  - by pragmaticCamel

  What is a good approach to an anti-spam algorithm for a website similar to reddit? Their anti-spam algorithm seems awfully broken (banning on words in the title and doing a horrible job for that matter). Considering a post spam because it has the word 'spam' in the title is really not a wise choice. Anyway, how can one approach such problem ? Are there any tools that help in such cases? Also, what are the /technical/ reasons behind reddit's choice not using reCAPTCHA on every post submission? It seems like a much better solution than what they have right now. Since reddit is basically a community-driven website why not give such power to the communities' trusted members?

• Subdomains vs. URL Path in shareable links

  - by Adam Matan

  I am building a web application for questions and answers. Each question/answer page has all the required metadata for Facebook and Twitter, and we encourage users to share these pages. I have a dilemma regarding the shared link structure: Option 1 - subdomains Use a questions.example.com and answers.example.com, followed by an ID and optional text. The text is ignored by the request, which only takes the id into account. http://questions.example.com/<question_id>/<question_text> http://questions.example.com/12345/how-long-is-the-queue # Example http://q.example.com/12345 # Example Option 2 - URL path This is the format used by stackoverflow.com and trello.com: http://example.com/questions/<question_id>/<question_text> http://example.com/questions12345/how-long-is-the-queue # Example http://example.com/q/12345 # Example Server-wise, I can easily do both - I have a wildcard SSL certificate and Apache/NGinx configuration is pretty straightforward. Which option - subdomains or URL path - is preferred for shareble links?

• How can I effectively use a netbook and a desktop computer together for programming?

  - by Mana

  Currently, in my workspace, I have a netbook sitting off to the side gathering dust while I write code on my desktop. As a result, the only use my netbook gets coding-wise is when I'm writing up a quick Python script to model a given problem or concept in class; I never use it at home for coding, or for anything at all, as it is all possible and faster on my (much more powerful) desktop. I feel like this is wrong and that I should be making better use of my netbook. What effective uses have you found for a netbook and a desktop together when programming (or for software development in general)? What are the merits of this practice?

• Ubuntu 12.04 x64 - Very slow response and sluggishness

  - by Murphy1138

  Recently updated to 12.04 x64 on my AMD HEX core 4GB system, over the last few days I feel that the overall system is sluggish/laggy , for instance hitting the dash button, the dash opens but the recent activity of files/videos etc is incredibly slow to populate, like wise in Nautilus and browsing my media, the file names are showing up but it takes an age to populate the "thumb" of the video, If I go into Gnome-shell the shell response is a little faster but again clicking on applications there is still a noticeable pause. I have the latest Nvidia Drivers loaded and I have very fast SATA drives, if I reboot into windows 7 the system is so much quicker in its response, I only use windows for games and Ubuntu is my main OS. 10.04/10.10/11.04 was Super quick and this was when the system still had a Duel Core Chip and a worse Nvidia card, 11.10 was pretty snappy, but 12.04 just feels bloated on each system I have installed it on. My hardware is more than up to the task so has anyone got any commands i can run to help diagnose the issue? Anyone else got the same problems? Thanks Murph

• Intersection of player and mesh

  - by Will

  I have a 3D scene, and a player that can move about in it. In a time-step the player can move from point A to point B. The player should follow the terrain height but slow going up cliffs and then fall back, or stop when jumping and hitting a wall and so on. In my first prototype I determine the Y at the player's centre's X,Z by intersecting a ray with every triangle in the scene. I am not checking their path, but rather just sampling their end-point for each tick. Despite this being Javascript, it works acceptably performance-wise. However, because I am modeling the player as a single point, the player can position themselves so that they are half-in a cliff face and so on. I need to model them as as a solid e.g. some cluster of spheres or a even their fuller mesh. I am also concerned that if they were moving faster they might miss the test altogether. How should I solve this?

• Settlers-like terrain representation

  - by Olle

  Remember this beauty? I'm playing it now on my old Amiga 1200. My question is: How do you think they represented the terrain, data structure wise? Obviously it's some kind of points, with a height. Or hexagons. And how did they decide which dots were buildable? EDIT: I could rephrase the question to say "how do I achieve this kind of terrain", but I would still only be interested in how to do it on a machine with 1 MB of RAM and a 7 Mhz processor, because this is the machine i currently developing games for. If that seems like a vague or meaningless question to you, that's alright, but I'm still curious if someone has any knowledge about this.

• Rendering trillions of "atoms" instead of polygons?

  - by Baring

  I just saw a video about what the publishers call the "next major step after the invention of 3D". According to the person speaking in it, they use a huge amount of atoms grouped into clouds instead of polygons, to reach a level of unlimited detail. They tried their best to make the video understandable for persons with no knowledge of any rendering techniques, and therefore or for other purposes left out all details of how their engine works. The level of detail in their video does look quite impressive to me. How is it possible to render scenes using custom atoms instead of polygons on current hardware? (Speed, memory-wise) If this is real, why has nobody else even thought about it so far? I'm, as an OpenGL developer, really baffled by this and would really like to hear what experts have to say. Therefore I also don't want this to look like a cheap advert and will include the link to the video only if requested, in the comments section.

• how to make game objects to contain other objects?

  - by user3161621

  Im pretty undecided about what path to take here. The simplest that comes to mind is just adding a field List to the GameObject class where i would store the things contained in it. But would it be elegant and well tought? And would it be good performance wise?(ofc 99.9% of my objects wouldnt have anything stored in them...) What about deriving a ContainerObject from GameObject? This way only they would have additional fields but then i would have to change many things, my collections of objects would have to become a generic and id have to cast very often into GameObject...

• Multiple parameters vs single parameter(object with multiple properties)

  - by Shwetanka

  I have an Entity Student with following properties - (name, joinedOn, birthday, age, batch, etc.) and a function fetchStudents(<params>). I want to fetch students based on multiple filters. In my method I have two ways to pass filters. Pass all filters as params to the method Make a class StudentCriteria with filters as fields and then pass the object of this class While working in java I always go with the second option but recently I'm working in php and I was advised to go with the first way. I am unable to figure out which way is better in maintaining the code, reusability and performance wise. Thanks.

• adjust the brightness in 13.04

  - by dinesh2707

  I have a dual graphics card: intel 4000 and nvidia 630m... I installed bumblebee and intel drivers from their website. I thought the brightness problem will be solved by installing these drivers. But, brightness works only for two steps: that is, dim, medium, high... But, it doesn't increase step wise. Can you please help me sort this problem? I'm a newbie to ubuntu and this is my first trial. So, please give me a detailed guide... Thank you :) EDIT: My model is HP DV6 7040tx. My Laptop Model

• Large Sprite Performance

  - by Iansen

  I've got a large Sprite generated using a set of vertices(x,y coordinates) and a bitmap pattern (using moveTo, lineTo, beginBitmapFill, endFill ...etc). It's about 15000 pixels wide and between 1500 - 2000 pixels high depending on the level -it's the terrain for a 2D game. My question is: what is the best way to display/move it on the stage - performance wise? Currently I'm just adding it to the stage as is...I get decent frame rate/ memory/ cpu usage but I want to optimize it for slower PCs. Any ideas? I've been reading a little about blitting but I'm not sure how to implement it in my case. Thanks.

• C# Printing and Zebra Printer

  - by Nathan

  I wrote a library which creates a bitmap image from some user input. This bitmap is then printed using a zebra printer. The problem I am running into is everything is very faint and blurry on the image printed by the zebra printer but if I print the bitmap to a laser printer it looks perfectly normal. Has anyone run into this before and if so how did they fix it? I have tried nearly everything I can think of printer settings wise.

• Panels-style UI for arbitrary CCK fields?

  - by ceejayoz

  I have a Drupal content type that has unlimited photo, textbox, and external link CCK fields, but while fields themselves can be reordered via drag-drop (i.e. photo B before photo A), I can't arbitrarily order amongst fields (i.e. photo B, link A, photo A, text A, link B). Panels is awesome, with its drag and drop, and just what I'm looking for interface-wise. Has anyone seen a Panels-style UI for ordering arbitrary collections of disparate CCK fields?

• Using ROWLOCK in an INSERT statement (MS SQL)

  - by RPS

  Would it be wise to use ROWLOCK on an insert statement that is copying large amounts of data and inserting it into the same table? Ex) INSERT INTO TABLE with (rowlock) (id, name) select newid, name) from TABLE with (nolock) where id = 1 Does anybody have recommendations on how to improve this statement, as I see when MS SQL gets busy it will end in Timeout Query returned for MS SQL.

• Floating point inaccuracy examples

  - by David Rutten

  How do you explain floating point inaccuracy to fresh programmers and laymen who still think computers are infinitely wise and accurate? Do you have a favourite example or anecdote which seems to get the idea across much better than an precise, but dry, explanation? How is this taught in Computer Science classes?

• Do you need a good background in OOP before moving to frameworks?

  - by ggfan

  Frameworks being all OOP, would it not be wise to go into frameworks without having a solid background in OOP? I can write basic classes but nothing too fancy or abstract. How much should I know of OOP before moving to frameworks? Right now I am PHP Object-Oriented Programming to learn OOP.

• T/SQL Efficiency and Order of Execution

  - by Kyle Rozendo

  Hi All, In regards to the order of execution of statements in SQL, is there any difference between the following performance wise? SELECT * FROM Persons WHERE UserType = 'Manager' AND LastName IN ('Hansen','Pettersen') And: SELECT * FROM Persons WHERE LastName IN ('Hansen','Pettersen') AND UserType = 'Manager' If there is any difference, is there perhaps a link etc. that you may have where one can learn more about this? Thanks a ton, Kyle

• WiX - Passing parameters to a CustomAction (DLL)

• Anonymous methods/functions: a fundamental feature or a violation of OO principles?

  - by RD1

  Is the recent movement towards anonymous methods/functions by mainstream languages like perl and C# something important, or a weird feature that violates OO principles? Are recent libraries like the most recent version of Intel's Thread Building Blocks and Microsofts PPL and Linq that depend on such things a good thing, or not? Are languages that currently reject anonymous methods/functions, like Java, making wise choices in sticking with a purely OO model, or are they falling behind by lacking a fundamental programming feature?
