• AND is better or using Internal "IF"

  - by BDotA

  In a situation like this:" if ((metadata != null) && (metadata.TypeEnum != VariantInfoMetadata.CellTypeEnum.Status)) do you recommend to keep the code as it is above or do you think it is better to make an internal "if" statement and brake that AND into two sections where "outer if" makes sure metadata is not null and inner if does the rest of the checking. I think this way will take care of possible null refrence exception if value of metadata gets null?

• How do I get a new license for gDEBugger after the 1 free year?

  - by Byte56

  I downloaded the gDEBugger from gremedy over a year ago, with their one year free license. The license has since expired and their site says that I'll be presented with the option for 1 year free license the first time I run it after install. This doesn't happen when re-installing, it just tells me the license has expired. How do I get a new license? I use this regularly for debugging shader problems and performance testing my game.

• Why can't `main` return a double or String rather than int or void?

  - by sunny

  In many languages such as C, C++, and Java, the main method/function has a return type of void or int, but not double or String. What might be the reasons behind that? I know a little bit that we can't do that because main is called by runtime library and it expects some syntax like int main() or int main(int,char**) so we have to stick to that. So my question is: why does main have the type signature that it has, and not a different one?

• OO Software Architecture - base class that everything inherits from. Bad/good idea?

  - by ale

  I am reviewing a proposed OO software architecture that looks like this: Base Foo Something Bar SomethingElse Where Base is a static class. My immediate thought was that every object in any class will inherit all the methods in Base which would create a large object. Could this cause problems for a large system? The whole architecture is hierarchical.. the 'tree' is much bigger than this really. Does this sort of architecture have a name (hierarchical?!). What are the known pros and cons?

• Is there any way to optimize my search blob program?

  - by Vicky

  I written this code to search the blob items (text files) on the basis of there content. For ex : if I search for "Good", then the files that contains "Good or good" word the name of that files should appear in search result. My code is working but i want to optimize it. class BlobSearch { public static int num = 1; static void Main(string[] args) { string accountName = "accountName"; string accessKey = "accesskey"; string azureConString = "DefaultEndpointsProtocol=https;AccountName=" + accountName + ";AccountKey=" + accessKey; string blob = "MyBlobContainer"; string searchText = string.Empty; Console.WriteLine("Type and enter to search : "); searchText = Console.ReadLine(); CloudStorageAccount account = CloudStorageAccount.Parse(azureConString); CloudBlobClient blobClient = account.CreateCloudBlobClient(); CloudBlobContainer blobContainer = blobClient.GetContainerReference(blob); blobContainer.FetchAttributes(); var blobItemList = blobContainer.ListBlobs(); GetBlobList(searchText, blobContainer, blobItemList); Console.ReadLine(); } private static async void GetBlobList(string searchText, CloudBlobContainer blobContainer, IEnumerable<IListBlobItem> blobItemList) { foreach (var item in blobItemList) { string line = string.Empty; CloudBlockBlob blockBlob = blobContainer.GetBlockBlobReference(item.Uri.ToString()); if (blockBlob.Name.Contains(".txt")) { await Search(searchText, blockBlob); } } } private async static Task Search(string searchText, CloudBlockBlob blockBlob) { string text = await blockBlob.DownloadTextAsync(); if (text.ToLower().IndexOf(searchText.ToLower()) != -1) { Console.WriteLine("Result : " + num + " => " + blockBlob.Name.Substring(blockBlob.Name.LastIndexOf('/') + 1)); num++; } } } I think blobContainer.ListBlobs(); is blocking code because search will not work until all the blob items loaded. Is there anyway to optimize it or anywhere else in my code. Thanks

• How to write comments to explain the "why" behind the callback function when the function and parameter names are insufficient for that?

  - by snowmantw

  How should I approach writing comments for callback functions? I want to explain the "why" behind the function when the function and parameter names are insufficient to explain what's going on. I have always wonder why comments like this can be so ordinary in documents of libraries in dynamic languages: /** * cb: callback // where's the arguments & effects? */ func foo( cb ) Maybe the common attitude is "you can look into source code on your own after all" which pushes people into leaving minimalist comments like this. But it seems like there should be a better way to comment callback functions. I've tried to comment callbacks in Haskell way: /** * cb: Int -> Char */ func foo(cb) And to be fair, it's usually neat enough. But it gets into trouble when I need to pass some complex structure. The problem being partly due to the lack of type system: /** * cb: Int -> { err: String -> (), success: () -> Char } // too long... */ func foo(cb) Or I have tried this too: /** * cb: Int -> { err: String -> (), * success: () -> Char } // better ? */ func bar(cb) The problem is that you may put the structure in somewhere else, but you must give it a name to reference it. But then when you name a structure you're about to use immediately looks so redundant: // Somewhere else... // ResultCallback: { err: String -> (), success: () -> Char } /** * cb: Int -> ResultCallback // better ?? */ func foo(cb) And it bothers me if I follow the Java-doc like commenting style since it still seems incomplete. The comments don't tell you anything that you couldn't immediately see from looking at the function. /** * @param cb {Function} yeah, it's a function, but you told me nothing about it... * @param err {Function} where should I put this callback's argument ?? * Not to mention the err's own arguments... */ func foo(cb) These examples are JavaScript like with generic functions and parameter names, but I've encountered similar problems in other dynamic languages which allow complex callbacks.

• What Scripting Program would you choose to recover deleted and missing files?

  - by Steven Graf

  For a private project I'm looking for a command line tool to scan and recover files. I'm working on Gnome 3 (but I could also change my OS if it helps reaching my goal) and must be able to find and recover files on attached devices with formats such as NTFS, Fat32, MAC OS Extended and ext3. Is there a command line script to cover all of them or do I need to use different programs to reach my goal? can you recommend command line tools for these kind of tasks? is one of you willing and able to show me some examples and teach me further?

  Which vendor provides better GPGPU. my requirements are confined to rendering utilising the GPU for BSDF building for e.g. Intel started providing Ivy Bridge chipset GPU, which are comparably fast to HD5960 cards. I'm not that against nvidia or amd. but I'm a fan of Intel. how it compares to nvidia in price and performance. if possible may I know, how all of them perform with OpenCL?? I'm not sure if it is right to ask it here. but I don't know where to ask.

• Is looking for code examples constantly a sign of a bad developer?

  - by Newly Insecure

  I am a comp sci student with several years of experience in C and C++, and for the last few years I've been constantly working with Java/Objective C doing app dev and now I have switched to web dev and am mainly focused on ruby on rails and I came to the realization that (as with app dev, really) I reference other code wayyyy too much. I constantly google functionality for lots of things I imagine I should be able to do from scratch and it's really cracked my confidence a bit. Basic fundamentals are not an issue, I hate to use this as an example but I can run through javabat in both java/python at a sprint - obviously not an accomplishment and but what I mean to say is I have a strong base for the fundamentals I think? I know what I need to use typically but reference syntax constantly. Would love some advice and input on this, as it has been holding me back pretty solidly in terms of looking for work in this field even though I'm finishing my degree. My main reason for asking is not really about employment, but more that I don't want to be the only guy at a hackathon not hammering out nonstop code and sitting there with 20 google/github tabs open, and I have refrained from attending any due to a slight lack of confidence... Is a person a bad developer by constantly looking to code examples for moderate to complex tasks?

  My company is building a website with database. Programmer's used PHP 5.0. My Service Provider (shared) in the meantime upgraded to PHP 5.3.0. Fixes have been on going and seem endless... Do I move to VPS and install older PHP or should we rebuild with newer PHP? When working remotely with programers what is the protocol regarding delivery of all code? Please what is the industry standard? I need an independent to review their work. How should this be approached?

• SQL Server Unit Testing with tSQLt

  When one considers the amount of time and effort that Unit Testing consumes for the Database Developer, is surprising how few good SQL Server Test frameworks are around. tSQLt , which is open source and free to use, is one of the frameworks that provide a simple way to populate a table with test data as part of the unit test, and check the results with what should be expected. Sebastian and Dennis, who created tSQLt, explain.

• SQL Server APPLY Basics

  One of the most interesting additions to SQL Server syntax in SQL Server 2005 was the APPLY operator. It allows several queries that were previously impossible. It is surprisingly difficult to find a simple explanation of what APPLY actually does. Rob Sheldon is the specialist in simple explanations, so we asked him.

• Implementing AS 2.0 with FSM?

  - by Up2u

  i have seen many of references of AI and FSM like : http://www.richardlord.net/blog/fini...n-actionscript and sadly im still can't understand the point of the FSM on AS2.0 is it a must to create a class of each state ? i have a project of game and also it has an AI, the AI has 3 state n i said the state is distanceCheck, ChaseTarget, and Hit the target, the game that i create is FPS game and play via by mouse so what i mean is i have create an AI ( and is success ) but i want to convert it to FSM method ... i create : function of CheckDistanceState() and in that function i have to locked the target with an array, and sort it with the nearest distance and locked it and it trigger the function ChaseState(), and in the ChaseState() i insert the Hit() function to destroy the enemy, the 3 function that i created , i call it in the AI_cursor.onEnterframe, ( FPS game that only have a cursor in stage ) is there any chance to implement FSM to my code without to create a class ?? from what i read before , to create a class mean to create an external code outside of the frame ( i used to code in frame) and i stil dont understand about it. sorry if my explaination not clear ...

• Problem with Update(GameTime) Methods and Pause implementation

  - by Adam

  I have the pause function implemented and it works correctly in that it dims the player screen and stops updating the gameplay. The problem is that GameTime continues to increase while it is paused, so my method that checks gameTime versus previousSpawnTime before spawning another enemy gets messed up and if the game is paused too long it is noticeable that the next enemy draws far too early. Here is my code for the enemy update. private void UpdateEnemies(GameTime gameTime) { // Spawn a new enemy every 1.5 seconds if (gameTime.TotalGameTime - previousSpawnTime > enemySpawnTime) { previousSpawnTime = gameTime.TotalGameTime; // Add an Enemy AddEnemy(); } ... I also have other methods that depend on gameTime. I've tried getting the total pause time and subtracting that from the total game time, but I can't seem to get it to work correctly if that is the way I should go about solving this. If you need to see any other code let me know. Thank you.

• How would I go about implementing a globe-like "ballish" map?

  - by rFactor

  I am new to 3D development and I have this idea of having the game world like our globe is - a ball. So, there would be no corners in the map and the game is top-down RTS game. I would like the camera to go on and on and never stop even though you are moving the camera to the same direction all the time. I am not sure if this is even possible, but I would really like to build a globe-like map without borders. Can this be done, and how exactly? I am using XNA, C#, and DirectX. Any tutorials or links or help is greatly appreciated!

• How do you keep track of the authors of code?

  - by garbagecollector

  This is something I was never taught. I have seen alot of different types of authoring styles. I code primarily in Java and Python. I was wondering if there was a standard authoring style or if everything is freestyle. Also if you answer would you mind attaching the style you use to author files that your create at home or at work. I usually just go @author garbagecollector @company garbage inc.

• Contiguous Time Periods

  It is always better, and more efficient, to maintain referential integrity by using constraints rather than triggers. Sometimes it is not at all obvious how to do this, and the history table, and other temporal data tables, presented problems for checking data that were difficult to solve with constraints. Suddenly, Alex Kuznetsov came up with a good solution, and so now history tables can benefit from more effective integrity checking. Joe explains...

• returning null vs returning zero, which would be better?

  - by Dark Star1

  I inherited a project that I am managing and having to maintain pending the redevelopment of the code base. At the moment I am being tasked with adding little feature all over the place and have gotten into the habit of returning null instead of zero in parts of the code where I am working on. The problem is we have a client that is using this code and parts of code that require data from my implemented features recieve a null and dump the stack trace in UI. I would like to avoid this entirely from my input but without the nullPointer exceptions there's the potential that errors would be introduced into the client's data which may go un-noticed. Usually I would have come up with my own error notification system but I have never inherited a project before. so I am unsure whether to continue down this path. I still believe that the stack dump is preferable to un-noticed data corruption/inaccuracies.

• I want to fix a bug. Where do I start?

  - by Ingo Gerth

  Although I am not a professional programmer, I have written a program or two. Yet, nowadays every engineer and scientist learns to program a bit as well, and as such I am used to writing programs in Python, C and MATLAB. Now I want to give back a bit to Ubuntu and its great folks and fix a bug! I had a look at the list of the bitesize campaign and had to find that most of them are not that easy for me to fix as I suspect they require a lot of time to get into the matter, and I do not have that. Still I discovered this one and it looks manageable and like a cool feature to me. As I have never written a patch or released a program to the wild before though, I have no idea where to start. What should be my first step to tackle that problem? Bottom line: Where and how do I start fixing that guy?

• Logic or Algorithm to solve this problem [closed]

  - by jade

  I have two lists. List1 {a,b,c,d,e} and List2 {f,g,h,i,j} The relation between the two list is as follows a->g,a->h,h->c,h->d,d->i,d->j Now I have these two lists displayed. Based on the relation above on selecting element a from List1, List2 shows g,h. On selecting h from List2, in List1 c,d are shown in List1. On selecting d from List1 it shows i,j in List2. How to trace back to initial state by deselecting the elements in reverse order in which they have been selected?

• Necessary Infrastructure for large project with many components communicating through IPCs

  - by jluzwick

  I have a fairly in depth question which probably doesn't have an exact answer. As a software engineer, I am usually tasked with working on a program or project with minimal understanding of how other components or programs in the project interact with each other. When one program fails in a sea of multiple components and processes, what infrastructure elements are necessary to ensure that the problem can be accurately tracked to the violating application? More specifically, what infrastructure elements should be necessary for this large project and which are optional but very helpful. One such example I can think of is some form of a common logging infrastructure that allows for a developer or tester to easily browse through a log that contains numerous components for messages that might allude to the culprit program along with a "trail" of what happened before the issue occurred. I'm thinking of something similar to Androids alogcat tool. These necessary infrastructure elements should be language-agnostic. While these elements should be understood by all engineers on the team in question, which elements should be understood at great detail by the technical system engineers and what should the individual software engineers be responsible for adding to their tools to allow for such infrastructures to take hold? Please feel free to ask for clarification if something does not make sense as I understand this question is very broad and needs some refinement. I will refine as necessary from the answers and comments I receive. Thanks for any help!

• How to switch off? [closed]

  - by Xophmeister

  While I've programmed software for many years, I've only recently started doing so professionally and have noticed a bit of a problematic pattern. I hope this is the best place to pose such a question, as I am interested in others' experiences and solutions... Writing software is, by its nature, a cerebral exercise. When coding for my own sake, I would do so until I was satisfied; even if that meant going all night. Now I'm coding in exchange for goods and services, on projects that are inherently uninteresting to me, I want to 'switch off' when it's time to go home. Maybe you consider that to be a 'bad attitude', but I just don't feel that whatever I'm working on is worth caring about after-hours. Besides, my employer doesn't exactly have the infrastructure required to make out-of-office changes; I can't just clone a repo and even remote login is a PITA. Anyway, the problem I'm experiencing is that, while I'm not particularly overworked or stressed, if I'm faced with a problem, my brain will work on a solution. Generally, it won't give up. Hence I can't switch off and, sometimes, the problem or the solution is significant enough that it disrupts my sleep. While, paradoxically, this doesn't seem to affect my coding ability, it can have a profound impact of the rest of my life. I get increasingly low as I get tired. So far, the best solutions I've found are writing little notes on the matter (and, say, e-mailing them back to my work address) and exercise. Neither of these can switch me off entirely and, as the week progresses, exercise especially becomes untenable due to tiredness. TL;DR How can you stop from being a coding zombie?
