• If you need more than 3 levels of indentation, you're screwed?

  - by jokoon

  Per the Linux kernel coding style document: The answer to that is that if you need more than 3 levels of indentation, you're screwed anyway, and should fix your program. What can I deduct from this quote? On top of the fact that too long methods are hard to maintain, are they hard or impossible to optimize for the compiler? I don't really understand if this quote encourages better coding practice or is really a mathematical / algorithmic sort of truth. I also read in some C++ optimizing guide that dividing up a program into more function improves its design is a common thing taught at school, but it should be not done too much, since it can turn into a lot of JMP calls (even if the compiler can inline some methods by itself).

• Getting Started with Component Architecture: DI?

  - by ashes999

  I just moved away from MVC towards something more component-architecture-like. I have no concept of messages yet (it's rough prototype code), objects just get internal properties and values of other classes for now. That issue aside, it seems like this is turning into an aspect-oriented-programming challenge. I've noticed that all entities with, for example, a position component will have similar properties (get/set X/Y/Z, rotation, velocity). Is it a common practice, and/or good idea, to push these behind an interface and use dependency injection to inject a generic class (eg. PositionComponent) which already has all the boiler-plate code? (I'm sure the answer will affect the model I use for message/passing)

• Synthetic database records

  - by michipili

  Assume we are getting some statistics from a customer which we analyse and we send our comments to the customer. Now, the customer tells us that the statistic they computed between January and March are based on a wrong methodology and sends us corrected series. We want perform analysis with the wrong and with the correct set of data, which are huge and only differ from January to March. Therefore, we need something like synthetic database records implementing the following logic: synthetic[1] = wrong_data synthetic[2] = correct_data between Januar and March, wrong_data otherwise With this, we can easily perform our analyses on synthetic records. Should such synthetic records be implemented in the application logic or on the side of the database? What are common pitfalls of such an implementation?

• Tracking 502 bad gateway error

  - by dasickle

  I moved my Wordpress site to WP Engine and now I constantly get 502 errors. I spoke with support and they said that its because I have a lot of DB queries. I ran some tests and my frontpage only has 95 queries and page size is about 500kb. Most inner pages are around 60 queries. All queries are very short. Some people tell me its common with WP Engine because they run nginx. Why do I keep getting these errors and is there a way to track how many of them happen on daily basis? P.S. WP Engine log is empty so cant see the 502's there.

• Unwittingly activate wrong wireless driver and now cannot activate the correct one

  - by Sumeth Chaochuti

  I just installed Kubuntu 10.10 on my MacBook 3,1 and found no wireless connection. Using KPackageKit I activated Broadcom b43 because it had already been selected for me. When I subsequently tried to activate Broadcom STA, however, I was returned with an error. After reading Jockey log I removed the wrong driver and reinstalled all drivers so that I can activate the correct one. It hasn't work even though KPackageKit now shows that I have installed: bcmwl-kernel-source bcmwl-modaliases broadcom-sta-common broadcom-sta-source According to the log it appears as if there are conflicts but I don't know how to rectify it. I'm completely new to the platform, just started using Kubuntu 2 days ago. I'll appreciate any advice anyone can give. Thanks.

• HTML5 Audio: Which formats? Ditch Ogg Vorbis in favor of Ogg Opus? Is MP3 still needed?

  - by phoibos

  I'm currently working on a website which has to stream audio files. Since bandwidth is always an issue, the file size should be as small as possible. I wonder what audio formats I should provide. MP3 - Most common format but low quality, I don't know if it's even required, since AAC is well supported by the browsers incapable of playing free codecs MP4 AAC - Nice quality / small filesize, supported by Safari / Mobile Devices / IE9 / Flash / Chrome A free codec - well, until recently, there only was Ogg Vorbis, but Ogg Opus is standardized now and it's really good! Questions: Is it time yet to use Opus instead if Vorbis? Firefox supports Opus since version 15, and Opera has support on its roadmap - I guess Chrome will follow in the future too. Do I still have to provide an MP3 file?

• Is it okay to have many Abstract classes in your application?

  - by JoseK

  We initially wanted to implement a Strategy pattern with varying implementations of the methods in a commmon interface. These will get picked up at runtime based on user inputs. As it's turned out, we're having Abstract classes implementing 3 - 5 common methods and only one method left for a varying implementation i.e. the Strategy. Update: By many abstract classes I mean there are 6 different high level functionalities i.e. 6 packages , and each has it's Interface + AbstractImpl + (series of Actual Impl). Is this a bad design in any way? Any negative views in terms of later extensibility - I'm preparing for a code/design review with seniors.

• Where should a programmer explain the extended logic behind the code?

  - by SRKX

  I have developed a few quantitative libraries in C# where it is important to understand not only the classic information that goes with the XMLDoc comments (which contains basic information with the method signature) but also the mathematical formulas being use within the methods. Hence I would like to be able to include extended documentation with the code, which could contain, for example Latex formulas, graphs, and so on. Do you think such information should be included in the API documentation? Or should it be included in a dev blog for examples? Are there common tools that are usually used for this kind of purposes?

• Tell a user whether they have already viewed an item in a list. How?

  - by user2738308

  It is pretty common for a web application to display a list of items and for each item in the list to indicate to the current user whether they have already viewed the associated item. An approach that I have taken in the past is to store HasViewed objects that contain the Id of a viewed item and the Id of the User who has viewed that item. When it comes time to display a list of items this requires querying for the items, and separately querying for the HasViewed objects, and then combining the results into a set of objects constructed solely for the purpose of displaying them in the view. Each e.g li then uses the e.g. has_viewed property of the objects constructed above. I would like to know whether others take a different approach and can recommend alternative ways to achieve this functionality.

• Back in Atlanta! Wed, Feb 9 2011

  - by KKline

  I always enjoy spending time with my friends from Atlanta, as well as meeting folks and making new friends. If you live in the Atlanta area, I hope you'll join me on the evening of Wednesday, February 9th, 2011. Details are at the Atlanta SQL Server user group website . It's common knowledge that I have a terrible memory for many things. However, one of the few things that my memory is usually really good at is remember names & faces (and remembering stories, but that is another story as well)....(read more)

• Finding the try for an except or finally [migrated]

  - by ?s?

  I'm dealing with some code that has fantastically long methods (10k lines!) and some odd use of try-finally and try-except blocks. Some of the latter are long by themselves, and don't always have the try at the start of the method. Obviously I'm trying to refactor the code, but in the meantime just being able to fix a couple of common pathologies would be much easier if I could jump to the start of a block and see what is happening there. When it's 20+ pages away finding it even with the CNPack rainbows is just tedious. I'm using D2010 and have GExperts (with DelForExp), CNPack and DDevExtensions installed, but I can't find anything that lets me jump from the try to the finally or back. Am I missing something? Is there another add-in that I can use that will get me this?

• Should I work for free while applying for a job?

  - by Jevgeni Bogatyrjov

  An employer usually asks a candidate to do a small project at home ("homework") as a part of applying for a job. Last time I applied for a job (as a web developer), there were aproximately 10 applicants who were all given different tasks. Despite the fact that there was only one vacancy, the company used the work of all of the candidates in one of its projects. Actually, it is quite reasonable for a company to create these "vacancies" just to make people work for free - I estimate, that aproximately 2 weeks of programmer's work was saved with all of the job applications that company had on one vacancy. Is this a common practice and how can you protect yourself from working for free in the future? Have you seen this during your career?

• Are things slow for you today - Check your DNS

  - by simonsabin

  Domain name resolution is a very common cause of delays when doing anything over the network whether its accessing a web page or connecting to SQL Server. Everything uses DNS. TCP/IP works with IP addresses and not friendly names. When using names you have to have a way of resolving names to IP addresses and thats what DNS does. If your DNS is wrong then you'll get delays and also potentially odd results. For instance if you have multiple DNS servers configured you may find that occasionally...(read more)

• What are the different branches of Programming? [closed]

  - by clueless

  I just want a very general overview about what are the actual 'branches' of programming in the industry. What are different paths one can choose as a programmer and what are the common frameworks/languages/platforms in those paths. Currently I'm well versed with C/C++ and Python and I'm a beginner with Django. I want to know this because I can't decide what to proceed with after this, which route to take. Hope it's not a very general question. Thanks!

• Tracking work history in a git repo

  - by Code-Guru

  Previous related questions: Code bases for desktop and mobile versions of the same app Git branching and tagging best practices Question: I have split my repo into three directories (swing, android, and common) as suggested by @KarlBielefeldt in response to my previous question. Now I am jumping back and forth between developing my Android port and tweaking/adding features to my original Swing app. All of my commits are linear (fast-forward) and only my commit messages give hints indicating whether I'm working on my Swing app or my Android app. Is there a better way to keep track of the work flow in my git repo?

• Programming Interview : How to debug a program?

  - by Jake

  I was recently asked the following question in an interview : How do you debug a C++ program ? I started by explaining that programs may have syntax and semantic errors. Compiler reports the syntax errors which can be corrected. For semantic errors, various debuggers are available. I specifically talked about gdb, which is command line, and Visual Studio IDE's debugger, which has a GUI, and common commands. I also talked about debug and release version of code, how assertions should be used for debug build, how exceptions helps in automatic cleanup & putting the program in valid state, and how logging can be useful (e.g. using std::clog). I want to know if this answer is complete or not. Also, I want to hear how other people will go about answering this question in a structured manner ? Thanks.

• Use of another country domain name can influence search engines results?

  - by DontVoteMeDown

  I'm studing a way to create my company domain based on it's name. Consider that my company's name is Another Store and I want to register a domain like anothersto.re - this is just an example. That domain is strictly chosen by marketing. What happens is that my company is stabilished in Brazil and our domain here is .br. The .re domain stands for an island near France so haves nothing to do with my country. If that domain is chosen what it can imply about SEO questions? Did it will have any influence on search engines results considering that they look over user's region? This kind of domain use became common between modern companies - and marketing strategies - and that is why I'm considering it.

• AndEngine player, background and camera

  - by valdemar593

  I'm developing a 2D shooter using AndEngine. At the moment I'm trying to make the camera follow the player. As I've understood the common approach is to use the SmoothCamera zooming it and setting the chased entity. The problem is that the camera follows the player WITH background moving also (RepeatingSpriteBackground), so it looks like the player doesn't move at all though the actual position changes. So I don't really get how to make the camera follow the player and have the background not moving. Thanks in advance.

• Interface design where functions need to be called in a specific sequence

  - by Vorac

  The task is to configure a piece of hardware within the device, according to some input specification. This should be achieved as follows: 1) Collect the configuration information. This can happen at different times and places. For example, module A and module B can both request (at different times) some resources from my module. Those 'resources' are actually what the configuration is. 2) After it is clear that no more requests are going to be realized, a startup command, giving a summary of the requested resources, needs to be sent to the hardware. 3) Only after that, can (and must) detailed configuration of said resources be done. 4) Also, only after 2), can (and must) routing of selected resources to the declared callers be done. A common cause for bugs, even for me, who wrote the thing, is mistaking this order. What naming conventions, designs or mechanisms can I employ to make the interface usable by someone who sees the code for the first time?

• Separating merged array of arithmetic and geometric series [closed]

  - by user1814037

  Possible Duplicate: Separating merged array of arithmetic and geometric series My friend asked me an interseting question. Given an array of positive integers in increasing order. Seperate them in two series, an arithmetic sequence and geometric sequence. The given array is such that a solution do exist. The union of numbers of the two sequence must be the given array. Both series can have common elements i.e. series need not to be disjoint. The ratio of the geometric series can be fractional. Example: Given series : 2,4,6,8,10,12,25 AP: 2,4,6,8,10,12 GP: 4,10,25 I tried taking few examples but could not reach a general way. Even tried some graph implementation by introducing edges if they follow a particular sequence but could not reach solution.
