• Drawing particles as a smooth blob

  - by Nömmik

  I'm new to game/graphics development and I'm playing around with particles (in 2D). I want to draw particles close to each other as a blob, just as liquid/water. I do not want to draw big circles overlapping as the blob won't be smooth (and too big). I don't really know physics but I assume what I want is something looking similar to surface tension. I haven't been able to find anything on stackexchange or on Google (maybe I do not know the correct keywords?). So far I have found two possible solutions, but I am unable to find any concrete information about algorithms. One of them is to calculate the concave hull of particles I consider being a blob. I can calculate the blob by creating an equivalence class (on the relation "close to each other"). Strangely enough I haven't been able to find any algorithm explaining how to calculate the concave hull. Many posts (and among stackexchange) links to libraries or commercial products that do this (I need libraries to work in C#), but never any algorithm. Also this solution might have a problem with a circle of particles, which would not detect the empty space in the middle. While researching concave hull I stumbled upon something called alpha shapes. Which seems to be exactly what I want to do, however just as with concave hull I haven't found any source explaining how they actually work. I have found some presentation materials but not enough to go on. It's like a big secret everyone knows except me :-/ After calculating the concave hull or alpha shape I want to make it a Bézier curve to make it smooth and nice. Although I do find my approach a bit too complex, maybe I am trying to solve this the wrong way? If you can either suggest any other solution to my problem, or explain the pieces I am missing I would be very happy and grateful :-) Thanks.

• Continual Professional Development - proving new skills to non-technical employers

  - by Tom

  Background I work in a non-IT based company, as a professional software developer, building a large scale internal database system. I am fortunate to have a fairly senior position within the company, and have been working here for around 4 years. Often I get asked by management "how do you learn new things?". To be honest, I don't know how to answer this. Over the last 6 months, I've really gotten my teeth into some new techniques and technologies to make my level of coding far better and hopefully improve the quality of the software. Even if it's just refreshing my skills on things I've learnt already. Like last week I dived into some complex XLinq and TPL code (.net). Nothing revolutionary, but I feel like I am a bit better than before. Question The question is, how do I prove this to my employer? It'd be nice to be able to put this on paper. Possibilities I could: Keep a journal of what I've learnt - keeping the technical bits in (nobody would understand or care, but it's better than them being omitted) ???? (I've run out of ideas already) Any ideas? Thanks, Tom

• Should I use procedural animation?

  - by user712092

  I have started to make a fantasy 3d fps swordplay game and I want to add animations. I don't want to animate everything by hand because it would take a lot of time, so I decided to use procedural animation. I would certainly use IK (starting with simple reaching an object with hand ...). I also assume procedural generation of animations will make less animations to do by hand (I can blend animations ...). I want also to have a planner for animation which would simplify complex animations; those which can be split to a sequence - run and then jump, jump and then roll - or which are separable - legs running and torso swinging with sword -. I want for example a character to chop a head of a big troll. If troll crouches character would just chop his head off, if it is standing he would climb on a troll. I know that I would have to describe the state ("troll is low", "troll is high", "chop troll head" ..) which would imply what regions animation will be in (if there is a gap between them character would jump), which would imply what places character can have some of legs and hands or would choose an predefined animation. My main goal is simplicity of coding, but I want my game to be looking cool also. Is it worthy to use procedural animation or does it make more troubles that it solves? (there can be lot of twiddling ...) I am using Blender Game Engine (therefore Python for scripting, and Bullet Physics).

• How to share problem solving knowledge in a multiteam group?

  - by jonathan

  I've been working in multiteam groups for as long as I'm a webdeveloper, for me a team can be a lonely soldier or several people, generally a company will have multiple teams working in different projects and once the project is out in the wild, any team can perform the maintenance. This is a small picture since I'm not talking only about project wise knowledge, but "craft wise" knowledge, but it gives the picture of how I'm used to work, so: Since we work on modularised teams, sometimes I feel like the teams are too tightly enclosed in their projects, I've seen cases where after an hour of discussion, someone asked the question aloud and other person totally unrelated answered in a much simpler fashion. The problem is not so simple to solve as people tend not to be available all the time, also sometimes people can't afford the time to go through a problem with the "asker", but could do it alone. I've thought about software based solutions, something in the lines of SE, but I'd like to know other programmers opinions on the subject. EDIT I don't know if this is a wikipedia complex, but I feel that Wikis don't encourage the user to actually ask questions, but rather to write articles, and sometimes we don't know the knowledge we need, before needing it.

• Rhino Mocks, AssertWasCalled with Arg Constraint on array parameter

  - by Etienne Giust

  Today, I had a hard time unit testing a function to make sure a Method with some array parameters was called. Method to be called : void AddUsersToRoles(string[] usernames, string[] roleNames);   I had previously used Arg<T>.Matches on complex types in other unit tests, but for some reason I was unable to find out how to apply the same logic with an array of strings.   It is actually quite simple to do, T really is a string[], so we use Arg<string[]>. As for the Matching part, a ToList() allows us to leverage the lambda expression.   sut.PermissionServices.AssertWasCalled(                 l => l.AddUsersToRoles(                     Arg<string[]>.Matches(a => a.ToList().First() == UserId.ToString())                     ,Arg<string[]>.Matches(a => a.ToList().First() == expectedRole1 && a.ToList()[1] == expectedRole2)                     )                     );   Of course, iw we expect an array with 2 or more values, the math would be something like : a => a.ToList()[0] == value1 && a.ToList()[1] == value2    … etc.

• How to number nested ordered lists.

  - by Wes

  Is there any way through CSS to style nested ordered lists to display sub numbers? The idea is similar to using heading levels. However what I'd really like to see is the following. Note each of these subsections has text not just a title. This isn't a real example just some organisational stuff. Now I know I can use <h1>-<h6> but nested lists would be much clearer and allow for different indentation styling. Also it would be symentically correct. Note I don't think that <h1>-<h6> are correct in many ways as the name doesn't apply to the whole section. 1 Introduction. 1.1 Scope Blah Blah Blah Blah Blah Blah 1.2 Purpose Blah Blah Blah Blah Blah Blah 2 Cars Blah Blah Blah Blah Blah Blah 2.1 engines sub Blah Blah Blah sub Blah Blah Blah 2.2 Wheels ... ... 2.10.21 hub caps sub-sub Blah Blah Blah sub-sub Blah Blah Blah 2.10.21.1 hub cap paint sub-sub-sub Blah Blah Blah sub-sub-sub Blah Blah Blah 3 Planes 3.1 Commercial Airlines. ... ... 212 Glossary

• How to manage a developer who has poor communication skills

  - by djcredo

  I manage a small team of developers on an application which is in the mid-point of its lifecycle, within a big firm. This unfortunately means there is commonly a 30/70 split of Programming tasks to "other technical work". This work includes: Working with DBA / Unix / Network / Loadbalancer teams on various tasks Placing & managing orders for hardware or infrastructure in different regions Running tests that have not yet been migrated to CI Analysis Support / Investigation Its fair to say that the Developers would all prefer to be coding, rather than doing these more mundane tasks, so I try to hand out the fun programming jobs evenly amongst the team. Most of the team was hired because, though they may not have the elite programming skills to write their own compiler / game engine / high-frequency trading system etc., they are good communicators who "can get stuff done", work with other teams, and somewhat navigate the complex beaurocracy here. They are good developers, but they are also good all-round technical staff. However, one member of the team probably has above-average coding skills, but below-average communication skills. Traditionally, the previous Development Manager tended to give him the Programming tasks and not the more mundane tasks listed above. However, I don't feel that this is fair to the rest of the team, who have shown an aptitute for developing a well-rounded skillset that is commonly required in a big-business IT department. What should I do in this situation? If I continue to give him more programming work, I know that it will be done faster (and conversly, I would expect him to complete the other work slower). But it goes against my principles, and promotes the idea that you can carve out a "comfortable niche" for yourself simply by being bad at the tasks you don't like.

• Self hosted PHP shopping cart with no storefront?

  - by Question

  I am looking for a shopping cart to implement on a simple website instead of the default paypal cart that is used with their add to cart buttons (I don't like the non-styeable new tab/window cart). However, I really like the ability to simply add the buttons to existing pages. I do not have a lot of products and do not want to deal with a storefront and complex templates. The main features I need: Self-hosted Easy to implement with existing website (copy and paste button code, etc.) Ability to have variations on one button with different prices (dropdown with sizes, colors, etc.) Ability to track inventory and disallow out of stock orders Ability to pass cart details to PayPal Website Payments Standard I have seen most of the large storefront options: oscommerce, zencart, cubecart, opencart, prestashop, magento, cs-cart, lemonstand, etc. but these are way more than I need. I don't need the storefront or customer accounts or templated pages, etc. I have seen e-junkie, which is not far off from what I would like, but it is not self-hosted and I would prefer an in-site cart (or dynamic overlay cart) rather than a lightbox or new tab/window cart. I also love the paypal minicart and its implementation, but there is no way to track inventory. So, does anyone have any recommendations that might meet these requests?

• 2-D Codes in Retail

  - by David Dorf

  The UPC you find on packaging is a one-dimensional barcode that's been in use, in one form or another, since the 1970s. While its a good symbology to encode numbers like a product identifier, its not really big enough to hold much more. It also requires a barcode scanner (like those connected to the POS), although iPhone apps like RedLaser have proved a mobile camera can be made to work in many situations. The next generation barcodes are two-dimensional and therefore capable of holding much more information as well as being more conducive to cameras. The most popular format is the QR Code, widely used in Japan because almost every mobile phone has a built-in reader. A typical use for QR Codes is to embed a URL so that that a mobile phone can quickly navigate to the specified web page. QR Codes can be found on posters, billboards, catalogs, and circulars. Speaking of which, Best Buy recently put a QR code in their circular as shown below. If fact, they even updated their iPhone application to include a QR Code reader. I was able to scan the barcode above right from the screen with my iPhone without issues, even though its fairly small in this image. Clearly they are planning to incorporate more QR Codes in their stores and advertising. If you haven't seen QR Codes before, you're not looking hard enough. They are around and will continue to spread.

• Is the development of CLI apps considered "backward"?

  - by user61852

  I am a DBA fledgling with a lot of experience in programming. I have developed several CLI, non interactive apps that solve some daily repetitive tasks or eliminate the human error from more complex albeit not so daily tasks. These tools are now part of our tool box. I find CLI apps are great because you can include them in an automated workflow. Also the Unix philosophy of doing a single thing but doing it well, and letting the output of a process be the input of another, is a great way of building a set of tools than would consolidate into an strategic advantage. My boss recently commented that developing CLI tools is "backward", or constitutes a "regression". I told him I disagreed, because most CLI tools that exist now are not legacy but are live projects with improved versions being released all the time. Is this kind of development considered "backwards" in the market? Does it look bad on a rèsumè? I also considered all solutions whether they are web or desktop, should have command line, non-interactive options. Some people consider this a waste of programming resources. Is this goal a worthy one in a software project?

• How do I choose the scaling factor of a 3D game world?

  - by concept3d

  I am making a 3D tank game prototype with some physics simulation, am using C++. One of the decisions I need to make is the scale of the game world in relation to reality. For example, I could consider 1 in-game unit of measurement to correspond to 1 meter in reality. This feels intuitive, but I feel like I might be missing something. I can think of the following as potential problems: 3D modelling program compatibility. (?) Numerical accuracy. (Does this matter?) Especially at large scales, how games like Battlefield have huge maps: How don't they lose numerical accuracy if they use 1:1 mapping with real world scale, since floating point representation tend to lose more precision with larger numbers (e.g. with ray casting, physics simulation)? Gameplay. I don't want the movement of units to feel slow or fast while using almost real world values like -9.8 m/s^2 for gravity. (This might be subjective.) Is it ok to scale up/down imported assets or it's best fit with a world with its original scale? Rendering performance. Are large meshes with the same vertex count slower to render? I'm wondering if I should split this into multiple questions...

• JQuery / JSON + .Net Service Layer - to WCF or Not to WCF?

  - by hanzolo

  I Recently had a discussion with a colleague of mine about the pros / cons of WCF. He mentioned about how much code is generated to support WCF, and also the overhead required. It was mentioned that a simple jQuery /Ajax post to a .aspx page (or a handler for that matter) that returns JSON would work more efficiently and takes much less code to implement. I am also aware of the new WCF Web API and feel that technology may solve the "bloated"-ness required in attaining a proxy etc... by just outputting JSON. So when developing a relational DB (MSSQL) storage model, with a fairly complex Business Layer (C#) and Data Access Layer (EntityFW).. what's a good technology for creating a "service layer" which will spit out View Models represented in JSON, with a CQRS(Command Query..) approach in mind.. The app would use the service layer to support it's required UI, as well as provide an available subset of services (outputting JSON data) for service subscribers.. In other words an admin panel to support the admin UI, and service endpoints that return JSON to access the configurations made from the administration UI. What are some potential technologies to use as the transport / communication layer. I'd like to use a pure RESTful approach, but am not against doing some URL rewriting with IIS. Obviously some of the available technologies are: WCF WCF Web API (should this even be separate?) Straight request / response (query string to .aspx / handler) Would using MVC .Net solve this entire problem? maybe their single page app approach? any suggestions / feedback from developing this type of application? Thanks,

• Convert MP3 to AAC,FLAC to AAC (.NET/C#) FREE :)

  - by PearlFactory

  So I was tasked with looking at converting 10 million tracks from mp3 320k to AAC and also Converting from mp3 320k to mp3 128k After a bit of hunting around the tool you need to use is FFMPEG Download x64 WindowsAlso for the best results get the Nero AACEncoder Download Now the command line STEP 1(From Flac)ffmpeg -i input.flac -f wav - | neroAacEnc -ignorelength -q 0.5 -if - -of output.m4aor (From mp3)ffmpeg -i input.mp3 -f wav - | neroAacEnc -ignorelength -q 0.5 -if - -of output.m4aNow the output.m4a is a intermediate state that we now put a ACC wrapper on via FFMpeg STEP 2ffmpeg -i output.m4a -vn -acodec copy final.aacDone :) There are a couple of options with the FFMPEG library as in we can look at importing the librarys and manipulation the API for the direct result FFMPEG has this support. You can get the relevant librarys from HereThey even have the source if you are that keen :-)In this case I am going to wrap the command lines into c# external process threads.( For the app that i am building to convert the 10 million tracks there is a complex multithreaded app to support this novel code )//Arrange Metadata about Call Process myProcess = new Process();ProcessStartInfo p = new ProcessStartInfo();string sArgs = string.format(" -i {0} -f wav - | neroAacEnc -ignorelength -q 0.5 -if - -of {1}",inputfile,outputfil) ; p.FileName = "ffmpeg.exe" ; p.CreateNoWindow = true; p.RedirectStandardOutput = true; //p.WindowStyle = ProcessWindowStyle.Normal p.UseShellExecute = false;//Execute p.Arguments = sArgs; myProcess.StartInfo = p; myProcess.Start(); myProcess.WaitForExit();//Write details about call  myProcess.StandardOutput.ReadToEnd();Now in this case we would execute a 2nd call using the same code but with different sArgs to put the AAC wrapper on the m4a file. Thats it. So if you need to do some conversions of any kind for you ASP.net sites/apps this is a great start and super fast.. With conversion times of around 2-3 seconds all of this can be done on the fly:-)Justin Oehlmannref : StackOverflow.com

• Reading source code to learn

  - by perl.j

  As you develop as a programmer, IMO, you begin to see different practices, different Algorithms, and "more than one way to do it". Seeing this code can be a great learning experience for you, even though you did not write the code. But is doing this only going to confuse you? For example, let's say you have a library in any language that was created by a colleague, and you have been using it for a while. You decide to look at the actual source code, regardless of how extensive it is, and get a better look at how this library is written. For the sake of example, the function you use most often from this library is the max function, which finds the largest of two numbers. But this function is a lot more complicated than it needs to be. The way it is written is confusing the heck out of you, and you don't know how this works. Will this make you a better programmer, because you realize how complicated it is for such a simple function, or will it make you a worse coder because you feel less confidant? So my question, in general, is does reading source code make you a better programmer and if so how? If not why do people still do it?.

• Code maintenance: keeping a bad pattern when extending new code for being consistent or not ?

  - by Guillaume

  I have to extend an existing module of a project. I don't like the way it has been done (lots of anti-pattern involved, like copy/pasted code). I don't want to perform a complete refactor. Should I: create new methods using existing convention, even if I feel it wrong, to avoid confusion for the next maintainer and being consistent with the code base? or try to use what I feel better even if it is introducing another pattern in the code ? Precison edited after first answers: The existing code is not a mess. It is easy to follow and understand. BUT it is introducing lots of boilerplate code that can be avoided with good design (resulting code might become harder to follow then). In my current case it's a good old JDBC (spring template inboard) DAO module, but I have already encounter this dilemma and I'm seeking for other dev feedback. I don't want to refactor because I don't have time. And even with time it will be hard to justify that a whole perfectly working module needs refactoring. Refactoring cost will be heavier than its benefits. Remember: code is not messy or over-complex. I can not extract few methods there and introduce an abstract class here. It is more a flaw in the design (result of extreme 'Keep It Stupid Simple' I think) So the question can also be asked like that: You, as developer, do you prefer to maintain easy stupid boring code OR to have some helpers that will do the stupid boring code at your place ? Downside of the last possibility being that you'll have to learn some stuff and maybe you will have to maintain the easy stupid boring code too until a full refactoring is done)

• An Interesting Perspective on Oracle's Mobile Strategy

  - by Carlos Chang

  Oracle’s well known for being an acquisitive company. On average, I think we acquire about 1 company a month. (don’t quote me, I didn't run the numbers)  With all the excitement around mobile, mobile and wait for it… mobile, well, you know...what' s up with that? Well, just to be clear and quote Schultz from Hogan's Heroes "I know nothing! Nothing! "  But I did recently run across this blog by Kevin Benedict over at mobileenterprisestrategies.com covering this very topic, Oracle Mobility Emerges Prepared for the Future,  a little (fair use) snippet here:"History, however, may reward Oracle's patience.  While veteran mobile platform vendors (including SAP) have struggled to keep up with the fast changing market, R&D investment requirements, the fickle preferences of mobile developers, and the emergence of cloud-based mobile services, Oracle has kept their focus on supporting mobile developers with integration services and tools that extend their solutions out to mobile apps.”It’s an interesting read, and I would encourage you to check it out here.   BTW, if you’re a Twitter user, follow our new account @OracleMobile To the first ten thousand followers, I bequeath you my sincere virtual thanks and gratitude. :)  For the dedicated mobile blog, go to blogs.oracle.com/mobile.

• Managing flash animations for a game

  - by LoveMeSomeCode

  Ok, I've been writing C# for a while, but I'm new to ActionScript, so this is a question about best practices. We're developing a simple match game, where the user selects tiles and tries to match various numbers - sort of like memory - and when the match is made we want a series of animations to take place, and when they're done, remove the tile and add a new one. So basically it's: User clicks the MC Animation 1 on the MC starts Animation 1 ends Remove the MC from the stage Add a new MC Start the animation on the new MC The problem I run into is that I don't want to make the same timeline motion tween on each and every tile, when the animation is all the same. It's just the picture in the tile that's different. The other method I've come up with is to just apply the tweens in code on the main stage. Then I attach an event handler for MOTION_FINISH, and in that handler I trigger the next animation and listen for that to finish etc. This works too, but not only do I have to do all the tweening in code, I have a seperate event handler for each stage of the animation. So is there a more structured way of chaining these animations together?

• Are there good resources for leading documentation for an existing software product having none?

  Hello. I'm a software developer at a technology company. I have been tasked with leading the documentation effort for the product I work on, both internal to developers as well as spilling over into facilitating the business side of requirements documentation. This internal product has been around for at least 6 years. One challenge is that this software application has no form of documentation other than some small, outdated pieces here and there. There are comments in the code, but they are technical and do not convey any over-arching behavior (even on technical side). As a consequence of having little to no documentation, this product is often unnecessarily complex under the covers adding to the challenge. We are very limited on time that will be given to us to work on documentation. Another thing about me is that I've displayed some ability in writing/communication around the office, but I'm not coming from any sort of documentation or formal writing background (beyond my academic career). Please share your advise or recommend resources, book/website/forum/whatever, for helping me come up with a plan with milestones, best practices, task delegation, templates, buy-in, etc. I'm hoping for a resource targeting or giving special mention of introducing good documentation on existing projects where there previously was none. I would be very grateful for your responses. Ben

• SQL SERVER – Storing Variable Values in Temporary Array or Temporary List

  - by pinaldave

  SQL Server does not support arrays or a dynamic length storage mechanism like list. Absolutely there are some clever workarounds and few extra-ordinary solutions but everybody can;t come up with such solution. Additionally, sometime the requirements are very simple that doing extraordinary coding is not required. Here is the simple case. Let us say here are the values: a, 10, 20, c, 30, d. Now the requirement is to store them in a array or list. It is very easy to do the same in C# or C. However, there is no quick way to do the same in SQL Server. Every single time when I get such requirement, I create a table variable and store the values in the table variables. Here is the example: For SQL Server 2012: DECLARE @ListofIDs TABLE(IDs VARCHAR(100)); INSERT INTO @ListofIDs VALUES('a'),('10'),('20'),('c'),('30'),('d'); SELECT IDs FROM @ListofIDs; GO When executed above script it will give following resultset. Above script will work in SQL Server 2012 only for SQL Server 2008 and earlier version run following code. DECLARE @ListofIDs TABLE(IDs VARCHAR(100), ID INT IDENTITY(1,1)); INSERT INTO @ListofIDs SELECT 'a' UNION ALL SELECT '10' UNION ALL SELECT '20' UNION ALL SELECT 'c' UNION ALL SELECT '30' UNION ALL SELECT 'd'; SELECT IDs FROM @ListofIDs; GO Now in this case, I have to convert numbers to varchars because I have to store mix datatypes in a single column. Additionally, this quick solution does not give any features of arrays (like inserting values in between as well accessing values using array index). Well, do you ever have to store temporary multiple values in SQL Server – if the count of values are dynamic and datatype is not specified early how will you about storing values which can be used later in the programming.

  - by pinaldave

  Six years ago, I started this SQLAuthority.com blog. There are so many things I want to say today – it is very very emotional. Instead of writing long I am including few images and cartoons. Last month we have also reached 50 Million Total Views on this blog. Here is the screen captured at that time. Click Image to Enlarge In 6 years there are total 2192 days (including 2 leap year day) and my total blog post count is 2300. That means I have been blogging more than 1 blog post every day. Here is the quick glance to all the numbers. Here you can find the list of all the 2300 blog posts. I am very glad to see my many of the friends stay in USA, India, United Kingdom, Canada and Australia in that order. You can see the geographic distribution of the support I receive on the blog from worldwide. On this day I would like to call out one 2 individuals who contribute equally or more in my success. When I started this blog 6 years ago, I was walking alone. After 2 years my wife Nupur joined my journey and 3 years later my daughter Shaivi joined the journey. Here is the example of the common conversation among us almost every day - Shaivi: Daddy, play catch-catch. Nupur: Shaivi, daddy will play with you once he finishes tomorrow’s blog. Shaivi: Daddy, Finish Blog. Okey. I play catch-catch (alone). SQLAuthority Family Well, thank you very much! We all love you!
