• Is NAN suitable for communicating that an invalid parameter was involved in a calculation?

  - by Arman

  I am currently working on a numerical processing system that will be deployed in a performance-critical environment. It takes inputs in the form of numerical arrays (these use the eigen library, but for the purpose of this question that's perhaps immaterial), and performs some range of numerical computations (matrix products, concatenations, etc.) to produce outputs. All arrays are allocated statically and their sizes are known at compile time. However, some of the inputs may be invalid. In these exceptional cases, we still want the code to be computed and we still want outputs not "polluted" by invalid values to be used. To give an example, let's take the following trivial example (this is pseudo-code): Matrix a = {1, 2, NAN, 4}; // this is the "input" matrix Scalar b = 2; Matrix output = b * a; // this results in {2, 4, NAN, 8} The idea here is that 2, 4 and 8 are usable values, but the NAN should signal to the receipient of the data that that entry was involved in an operation that involved an invalid value, and should be discarded (this will be detected via a std::isfinite(value) check before the value is used). Is this a sound way of communicating and propagating unusable values, given that performance is critical and heap allocation is not an option (and neither are other resource-consuming constructs such as boost::optional or pointers)? Are there better ways of doing this? At this point I'm quite happy with the current setup but I was hoping to get some fresh ideas or productive criticism of the current implementation.

• How important do you find exception safety to be in your C++ code?

  - by Kai

  Every time I consider making my code strongly exception safe, I justify not doing it because it would be so time consuming. Consider this relatively simple snippet: Level::Entity* entity = new Level::Entity(); entity->id = GetNextId(); entity->AddComponent(new Component::Position(x, y)); entity->AddComponent(new Component::Movement()); entity->AddComponent(new Component::Render()); allEntities.push_back(entity); // std::vector entityById[entity->id] = entity; // std::map return entity; To implement a basic exception guarantee, I could use a scoped pointer on the new calls. This would prevent memory leaks if any of the calls were to throw an exception. However, let's say I want to implement a strong exception guarantee. At the least, I would need to implement a shared pointer for my containers (I'm not using Boost), a nothrow Entity::Swap for adding the components atomically, and some sort of idiom for atomically adding to both the Vector and Map. Not only would these be time consuming to implement, but they would be expensive since it involves a lot more copying than the exception unsafe solution. Ultimately, it feels to me like that time spent doing all of that wouldn't be justified just so that the a simple CreateEntity function is strongly exception safe. I probably just want the game to display an error and close at that point anyway. How far do you take this in your own game projects? Is it generally acceptable to write exception unsafe code for a program that can just crash when there is an exception?

• Pattern for Accessing MySQL connection

  - by Dipan Mehta

  We have an application which is C++ trying to access MySQL database. There are several (about 5 or so) threads in the application (with Boost library for threading) and in each thread has a few objects, each of which is trying to access Database for its' own purpose. It has a simple ORM kind of model but that really is not an important factor here. There are three potential access patterns i can think of: There could be single connection object per application or thread and is shared between all (or group). The object needs to be thread safe and there will be contentions but MySQL will not be fired with too many connections. Every object could initiate connection on its own. The database needs to take care of concurrency (which i think MySQL can) and the design could be much simpler. There could be two possibilities here. a. either object keeps a persistent connection for its life OR b. object initiate connection as and when needed. To simplify the contention as in case of 1 and not to create too many sockets as in case of 2, we can have group/set based connections. So there could be there could be more than one connection (say N), each of this connection could be shared connection across M objects. Naturally, each of the pattern has different resource cost and would work under different constraints and objectives. What criteria should i use to choose the pattern of this for my own application? What are some of the advantages and disadvantages of each of these pattern over the other? Are there any other pattern which is better? PS: I have been through these questions: mysql, one connection vs multiple and MySQL with mutiple threads and processes But they don't quite answer exactly what i am trying to ask.

• Best practice for assigning A/B test variation based on IP address

  - by mojones

  I am starting to write some code for A/B testing in a Grails web application. I want to ensure that requests from the same IP address always see the same variation. Rather than store a map of IP-variant, is it OK to simply turn the IP address into an integer by removing the dots, then use that as the seed for a random number generator? The following is taking place in a Grails Filter: def ip = request.remoteAddr def random = new Random(ip.replaceAll(/\./, '').toInteger()) def value = random.nextBoolean() session.assignment = value // value should always be the same for a given IP address I know that identifying users by IP address is not reliable, and I will be using session variables/cookies as well, but this seems to be useful for the case where we have a new session, and no cookies set (or the user has cookies disabled).

• regex to match postgresql bytea

  - by filiprem

  In PostgreSQL, there is a BLOB datatype called bytea. It's just an array of bytes. bytea literals are output in the following way: '\\037\\213\\010\\010\\005`Us\\000\\0001.fp3\'\\223\\222%' See PostgreSQL docs for full definition of the format. I'm trying to construct a Perl regular expression which will match any such string. It should also match standard ANSI SQL string literals, like 'Joe', 'Joe''s Mom', 'Fish Called ''Wendy''' It should also match backslash-escaped variant: 'Joe\'s Mom', . First aproach (shown below) works only for some bytea representations. s{ ' # Opening apostrophe (?: # Start group [^\\\'] # Anything but a backslash or an apostrophe | # or \\ . # Backslash and anything | # or \'\' # Double apostrophe )* # End of group ' # Closing apostrophe }{LITERAL_REPLACED}xgo; For other (longer ones, with many escaped apostrophes, Perl gives such warning: Complex regular subexpression recursion limit (32766) exceeded at ./sqa.pl line 33, < line 1. So I am looking for a better (but still regex-based) solution, it probably requires some regex alchemy (avoiding backreferences and all).

• Kinect will recognise your finger movement

  - by Boonei

  Sources inside Microsoft suggest they MS guys are tying to improve motion controller. This could be a huge boost to gaming. There are quite a few things that we can do with our fingers when playing games like driving, shooting,sports etc. If fingers are captured then  XBox will give more realistic version of our avatar. Eurogamer has also suggested the same according to their sources. It would be only(mostly) a software update and would not require a new camera, because the USB controller interface currently in place in Kinect can take in data up-to 35MBps. The current utilization is only around roughly 1/2 of it. So there is currently a facility to send more data. Little more tech data, Kinect does transmit 320×240-pixel in 30 fps, if the device could capture and transfer at 640×480 pixels, then better resolution can detect more movements compared to current level of detection. Lets wait and watch ! This article titled,Kinect will recognise your finger movement, was originally published at Tech Dreams. Grab our rss feed or fan us on Facebook to get updates from us.

• Initialization of std::vector<unsigned int> with a list of consecutive unsigned integers

  - by Thomas

  I want to use a special method to initialize a std::vector<unsigned int> which is described in a C++ book I use as a reference (the German book 'Der C++ Programmer' by Ulrich Breymann, in case that matters). In that book is a section on sequence types of the STL, referring in particular to list, vector and deque. In this section he writes that there are two special constructors of such sequence types, namely, if Xrefers to such a type, X(n, t) // creates a sequence with n copies of t X(i, j) // creates a sequence from the elements of the interval [i, j) I want to use the second one for an interval of unsigned int, that is std::vector<unsigned int> l(1U, 10U); to get a list initialized with {1,2,...,9}. What I get, however, is a vector with one unsigned int with value 10 :-| Does the second variant exist, and if yes, how do I force that it is called?

• Delphi - COM/OLE starting example needed

  - by durumdara

  Hi! 10 years have ellapsed since I used COM/OLE, and I forget 90% of them. Now we need to make a COM object to access some data from PHP/Python (this is specific thing, the php ODBC don't access the output params of a DataBase - like stored proc output), and my idea the I realize a minimal object with one method, and PHP/Python can call this to get the output... procedure ExecSQL(Config, IP, Port, DBName, SQL, IDFieldName : variant) : output output is [IDValue, ErrorMsg, HResult] Please help me a very little example, how to start it? I need only this, but I'm confused by many ActiveX/COM in the palette. What I need to use to make a simple COM DLL, and how to register my COM object with this DLL? Thanks: dd

• OpenGL CPU vs. GPU

  - by Nitrex88

  So I've always been under the impression that doing work on the GPU is always faster than on the CPU. Because of this, in OpenGL, I usually try to do intensive tasks in shaders so they get the speed boost from the GPU. However, now I'm starting to realize that some things simply work better on the CPU and actually perform worse on the GPU (particularly when a geometry shader is involved). For example, in a recent project I did involving procedurally generated terrain, I tried passing a grid of single triangles into a geometry shader, and tesselated each of these triangles into quads with 400 vertices whose height was determined by a noise function. This worked fine, and looked great, but easily maxed out the GPU with only 25 base triangles and caused a very slow framerate. I then discovered that tesselating on the CPU instead, and setting the height (using noise function) in the vertex shader was actually faster! This prompted me to question the benefits of using the GPU as much as possible... So, I was wondering if someone could describe the general pros and cons of using the GPU vs CPU for intensive graphics tasks. I know this mainly comes down to what your trying to achieve, so if necessary, use the above scenario to discuss why the "CPU + vertex shader" was actually faster than doing everything in the geometry shader on the GPU. It's possible my hardware (newest macbook pro) isn't optomized well for the geometry shader (thus causing the slow framerate). Also, I read that the vertex shader is very good with parallelism, and would love a quick explanation of how this may have played a role in speeding up my procedural terrain. Any info/advice about CPU/GPU/shaders would be awesome!

• IPv6 parsing in C

  - by The Stig

  I wanted to know how i can parse an IPv6 address in 'C' and convert it to a 128 bit value? So a hex address like 1:22:333:aaaa:b:c:d:e:f needs to be converted to its 128 bit equivalent binary. The problem is the IP address could be of the type ::2 and its variant since they are valid IPv6 address. The input is from the keyboard and hence is in ASCII format. Any suggestions or pointers will be appreciated. Thanks!!!

• How do you cope with change in open source frameworks that you use for your projects?

  - by Amy

  It may be a personal quirk of mine, but I like keeping code in living projects up to date - including the libraries/frameworks that they use. Part of it is that I believe a web app is more secure if it is fully patched and up to date. Part of it is just a touch of obsessive compulsiveness on my part. Over the past seven months, we have done a major rewrite of our software. We dropped the Xaraya framework, which was slow and essentially dead as a product, and converted to Cake PHP. (We chose Cake because it gave us the chance to do a very rapid rewrite of our software, and enough of a performance boost over Xaraya to make it worth our while.) We implemented unit testing with SimpleTest, and followed all the file and database naming conventions, etc. Cake is now being updated to 2.0. And, there doesn't seem to be a viable migration path for an upgrade. The naming conventions for files have radically changed, and they dropped SimpleTest in favor of PHPUnit. This is pretty much going to force us to stay on the 1.3 branch because, unless there is some sort of conversion tool, it's not going to be possible to update Cake and then gradually improve our legacy code to reap the benefits of the new Cake framework. So, as usual, we are going to end up with an old framework in our Subversion repository and just patch it ourselves as needed. And this is what gets me every time. So many open source products don't make it easy enough to keep projects based on them up to date. When the devs start playing with a new shiny toy, a few critical patches will be done to older branches, but most of their focus is going to be on the new code base. How do you deal with radical changes in the open source projects that you use? And, if you are developing an open source product, do you keep upgrade paths in mind when you develop new versions?

• Doing powerups in a component-based system

  - by deft_code

  I'm just starting really getting my head around component based design. I don't know what the "right" way to do this is. Here's the scenario. The player can equip a shield. The the shield is drawn as bubble around the player, it has a separate collision shape, and reduces the damage the player receives from area effects. How is such a shield architected in a component based game? Where I get confused is that the shield obviously has three components associated with it. Damage reduction / filtering A sprite A collider. To make it worse different shield variations could have even more behaviors, all of which could be components: boost player maximum health health regen projectile deflection etc Am I overthinking this? Should the shield just be a super component? I really think this is wrong answer. So if you think this is the way to go please explain. Should the shield be its own entity that tracks the location of the player? That might make it hard to implement the damage filtering. It also kinda blurs the lines between attached components and entities. Should the shield be a component that houses other components? I've never seen or heard of anything like this, but maybe it's common and I'm just not deep enough yet. Should the shield just be a set of components that get added to the player? Possibly with an extra component to manage the others, e.g. so they can all be removed as a group. (accidentally leave behind the damage reduction component, now that would be fun). Something else that's obvious to someone with more component experience?

• The Science Behind Salty Airline Food

  - by Jason Fitzpatrick

  In this collection, Artist Signe Emma combines a scientific overview of the role salt plays in airline food with electron microscope scans of salt crystals arranged to look like the views from an airplane–a rather clever and visually stunning way to deliver the message. Attached to the collection is this explaination of why airlines load their snacks and meals with salt: White noise consists of a random collection of sounds at different frequencies and scientists have demonstrated that it is capable of diminishing the taste of salt. At low-pressure conditions, higher taste and odour thresholds of flavourings are generally observed. At 30.000 feet the cabin humidity drops by 15%, and the lowered air pressure forces bodily fluids upwards. With less humidity, people have less moisture in their throat, which slows the transport of odours to the brains smell and taste receptors. That means that if a meal should taste the same up in the air, as on ground it needs 30% of extra salt. To combat the double assault on our sense of taste, the airlines boost the salt content to compensate. For more neat microscope scans as high-altitude view photographs, hit up the link below.

• Actionscript: Why is drawRoundRectComplex() not documented?

  in studying actionscript 3's graphics class, i've come across the undocumented drawRoundRectComplex() method. it's a variant of drawRoundRect() but with 8 parameters, the final four being the diameter of each corner (x, y, width, height, top left, top right, bottom left, bottom right). //example var sp:Sprite = new Sprite(); sp.graphics.lineStyle(1, 0x000000); sp.graphics.drawRoundRectComplex(0, 0, 100, 50, 10, 20, 0, 10); addChild(sp); this seems to be a pretty useful method, so i'm just curious if anyone knows of any reasons why adobe chose not to document it?

• How can I hide the taxonomy field for authenticated users but show it for other users in Drupal 6?

  - by Jaymie

  I have a Drupal (v6.17) Content Type which includes a Taxonomy field. I want to hide this from ordinary Authenticated Users, but want it available to my Site Contributor role users, so they can review and then assign tags to user-created nodes. I've tried overriding the Node Add/Edit form in Panels 3 by creating a panel variant especially for Authenticated Users, which would exclude the Taxonomy field. However, the Taxonomy field is bundled in with the "General Form" controls - without showing this, I don't get the Title and Body fields. Is there a way I can either include the Title and Body fields without Taxonomy, OR hide just the Taxonomy field when the authenticated user role creates a node. I realise there's a CCK field which might be able to help me out here, but how do I tie that to the Taxonomy module? Any help gratefully received.

' Populate the array with the whole recordset. vaData = rst.GetRows What differences exist between VB and VBA which makes this type of operation not work? What about performance concerns? Is this an "expensive" operations?

• Performance of concurrent software on multicore processors

  - by Giorgio

  Recently I have often read that, since the trend is to build processors with multiple cores, it will be increasingly important to have programming languages that support concurrent programming in order to better exploit the parallelism offered by these processors. In this respect, certain programming paradigms or models are considered well-suited for writing robust concurrent software: Functional programming languages, e.g. Haskell, Scala, etc. The actor model: Erlang, but also available for Scala / Java (Akka), C++ (Theron, Casablanca, ...), and other programming languages. My questions: What is the state of the art regarding the development of concurrent applications (e.g. using multi-threading) using the above languages / models? Is this area still being explored or are there well-established practices already? Will it be more complex to program applications with a higher level of concurrency, or is it just a matter of learning new paradigms and practices? How does the performance of highly concurrent software compare to the performance of more traditional software when executed on multiple core processors? For example, has anyone implemented a desktop application using C++ / Theron, or Java / Akka? Was there a boost in performance on a multiple core processor due to higher parallelism?
