• Established coding standards for pl/pgsql code

  - by jb01

  I need to standardize coding practises for project that compromises, among others has pl/pgsql database, that has some amount of nontrivial code. I look for: Code formatting guidelines, especially inside procedures. Guidelines on what constructs are consigered unsafe (if any) Naming coventions. Code documentation conventions (if this is pracicised) Any hints to documets that define good practises in pl/pgsql code? If not i'm looking for hints to practices that you consider good. There is related question regarding TSQL: Can anyone recommend coding standards for TSQL?, which is relevant to psql as well, but I need more information on stored procedures. Other related questions: http://stackoverflow.com/questions/1070275/what-indenting-style-do-you-use-in-sql-server-stored-procedures

• Do you think code is self documenting?

  - by Desolate Planet

  This is a question that was put to me many years ago as a gradute in a job interview and it's kind of picked at my brain now and again and I've never really found a good answer that satisfies me. The interviewer in question was looking for a black and white answer, there was no middle ground. I never got the chance to ask about the rationale behind the question, but I'm curious why that question would be put to a developer and what you would learn from a yes or no answer? From my own point of view, I can read Java, Python, Delphi etc, but if my manager comes up to me and asks me how far along in a project I am and I say "The code is 80% complete" (and before you start shooting me down, I've heard this uttered in a couple of offices by developers), how exactly is that self documenting? Apologies if this question seems strange, but I'd rather ask and get some opinions on it to gain a better understanding of why it would be put to someone in an interview.

• Error in my Separating Axis Theorem collision code

  - by Holly

  The only collision experience i've had was with simple rectangles, i wanted to find something that would allow me to define polygonal areas for collision and have been trying to make sense of SAT using these two links Though i'm a bit iffy with the math for the most part i feel like i understand the theory! Except my implementation somewhere down the line must be off as: (excuse the hideous font) As mentioned above i have defined a CollisionPolygon class where most of my theory is implemented and then have a helper class called Vect which was meant to be for Vectors but has also been used to contain a vertex given that both just have two float values. I've tried stepping through the function and inspecting the values to solve things but given so many axes and vectors and new math to work out as i go i'm struggling to find the erroneous calculation(s) and would really appreciate any help. Apologies if this is not suitable as a question!

• Build Controller status Unavailable issue in TFS2010

  - by jehan

  I ran into this problem few days back, I was not able to run the builds because the Build Controller was showing Status as Unavailable. It was showing the below exception: There was no endpoint listening at http://fullmachinename:9191/Build/v3.0/Services/Controller/2 that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. After trying out few things, I looked at below Build Service Properties.   Then, I did below modifications to the Build Services Properties: 1)      Changed the Local Build Service Endpoint(incoming) from http://machinename.domain.com:9191 to http://machinename:9191 2)      Changed the Connect to Team Project Collection (outgoing) from localhost to machine name. http://localhost:8080/tfs/defaultCollection to http://machinename:8080/tfs/DefaultCollection   After that Started the Build Services and it fixed the issue, the Build Controller was showing Available Status and was able to run the builds.

• Managed code and the Shell – Do?

  Back in 2006 I wrote a blog post titled: Managed code and the Shell – Don't!. Please visit that post to see why that advice was given.The crux of the issue has been addressed in the latest CLR via In-Process Side-by-Side Execution. In addition to the MSDN documentation I just linked, there is also an MSDN article on the topic: In-Process Side-by-Side.Now, even though the major technical impediment seems to be removed, I don’t know if Microsoft is now officially supporting managed extensions to the shell. Either way, I noticed a CodePlex project that is marching ahead to enable exactly that: Managed Mini Shell Extension Framework. Not much activity there, but maybe it will grow once .NET 4 is released... Comments about this post welcome at the original blog.

• Make methods that do not depend on instance fields, static?

  - by m3th0dman

  Recently I started programming in Groovy for a integration testing framework, for a Java project. I use Intellij IDEA with Groovy plug-in and I am surprised to see as a warning for all the methods that are non-static and do not depend on any instance fields. In Java, however, this is not an issue (at least from IDE's point of view). Should all methods that do not depend onto any instance fields be transformed into static functions? If true, is this specific to Groovy or it is available for OOP in general? And why?

• Do you develop with localization in mind?

  - by Jimmy C

  When working on a software project or a website, do you develop with localization in mind? By this I mean e.g. Externalizing all strings, including error messages. Not using images that contain text. Designing your UI with text expansion in mind. Using pseudo-translation to test your UI's early in the process. etc. On projects you work on, are these in the 'nice to have' category and let the L10N team worry about the rest, or do you have localization readiness built into your development process? I'm interested to hear how developers view localization in general.

• How important are unit tests in software development?

  - by Lo Wai Lun

  We are doing software testing by testing a lot of I/O cases, so developers and system analysts can open reviews and test for their committed code within a given time period (e.g. 1 week). But when it come across with extracting information from a database, how to consider the cases and the corresponding methodology to start with? Although that is more likely to be a case studies because the unit-testing depends on the project we have involved which is too specific and particular most of the time. What is the general overview of the steps and precautions for unit-testing?

• How to understand Linux kernel source code for a beginner?

  - by Amit Chavan

  Hi, I am a student interested in working on Memory Management, particularly the page replacement component of the linux kernel. What are the different guides that can help me to begin understanding the kernel source? I have tried to read the book Understanding the Linux Virutal Memory Manager by Mel Gorman and Understanding the Linux Kernel by Cesati and Bovet, but they do not explain the flow of control through the code. They only end up explaining various data structures used and the work various functions perform. This makes the code more confusing. My project deals with tweaking the page replacement algorithm in a mainstream kernel and analyse its performance for a set of workloads. Is there a flavor of the linux kernel that would be easier to understand(if not the linux-2.6.xx kernel)?

• Naming conventions used for variables and functions in C

  - by Zel

  While coding a large project in C I came upon a problem. If I keep on writing more code then there will be a time when it will be difficult for me to organize the code. I mean that the naming for functions and variables for different parts of the program may seem to be mixed up. So I was thinking whether there are useful naming conventions that I can use for C variables and functions? Most languages suggest a naming convention. But for C the only thing I have read so far is the names should be descriptive for code readability. EDIT: Examples of some examples of suggested naming conventions: Python's PEP 8 Java Tutorial I read some more naming conventions for java somewhere but couldn't remember where.

• ASP.NET MVC Cookbook &ndash; public review

  I have recently started writing another book. The topic of this book is ASP.NET MVC. This book differs from my previous book in that rather than working towards building one project from end to end this book will demonstrate specific topics from end to end. It is a recipe book (hence the cookbook name) and will be part of the Packt Publishing cookbook series. An example recipe in this book might be how to consume JSON, creating a master /details page, jquery modal popups, custom ActionResults, etc....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How important is using the same language for client and server?

  - by Makita

  I have been evaluating architecture solutions for a mobile project that will have a web-service/app in addition to native apps and have been looking at various libraries, frameworks, and stacks like Meteor, this being a sort of "open stack package framework", is tightly bound with Node.js. There is a lot of talk about the benefits of using the same language both client and server side, and I'm not getting it. I could understand if you want to mirror the entire state of a web application on both client and server but struggling to find other wins... Workflow efficiency? I'm trying to understand why client/server language parity is considered to be a holy grail. Why does client/server language parity matter in software development?

• Is a Single Texture Cube Map Possible?

  - by smoth190

  I'm currently developing a test project to explore OpenGL 3 texturing abilities. I have a simple cube, made of 8 vertices and 36 indices. I want each of the cubes faces to have a different texture, so I devised this texture: I made it obvious which sections I want visible (I hope...). In Direct3D, I once made a skybox, and I used a cubemap. However, I had to split it into 6 different textures. This is annoying and hard to manage, it would be nice to have just one texture. Is this even possible? I read somewhere that I could do this by duplicating vertices, is that a good idea? Someone else said I could do it in the shader, but that also baffles me...

• How do you make comp.sci students and future programmers aware of the various software licenses and the nuances of it ?

  - by Samyak Bhuta

  To be specific How would you include it as part of curriculum ? Would it be too boring to just introduce them as a pure law subject ? Are there any course structure available or can we derive one ? What are the books that could be used ? I would like to see that - after going through the course - candidate is well aware of "what software licenses are and what they are good for". Various implications of not knowing it in it's proper sense. What licenses they should use for their own code. What to consider when they are trying to use certain libraries or tools in their project and gauge risks/rewards associated with it. The idea is to let them make informed choices when they are professionals/practitioners in field of programming and not make them substitute for a lawyer or even a paralegal who is going to fight the case or draft things.

• How do I know when should I package my classes in Ruby?

  - by Omega

  In Ruby, I'm creating a small game development framework. Just some personal project - a very small group of friends helping. Now I am in need of handling geometric concepts. Rectangles, Circles, Polygons, Vectors, Lines, etc. So I made a class for each of these. I'm stuck deciding whether I should package such classes in a module, such as Geometry. So I'd access them like Geometry::Rectangle, or just Rectangle if I include the module. Now then, my question isn't about this specific scenario. I'd like to know, when is it suitable to package similar classes into one module in Ruby? What factors should I consider? Amount of classes? Usage frequency? Complexity?

• Rationale behind freeware projects

  - by VexXtreme

  I've seen some freeware projects in the past where the author(s) invested a significant amount of their personal time and resources and never even considered charging for the software. A lot of these projects were donation based, and from what I've heard, donationware can never be a viable business model (even to simply support development costs) because most people choose not to donate if given an option. A lot of these projects eventually shut down because their authors could not sustain them further. Granted, some people simply like making the community happy (or something), but if you're struggling to keep your project alive, why not charge some small amount such as $10 simply to stay operational? If people find your software useful (and a lot of people found those projects VERY useful) they won't have a problem paying such a small amount. The question is: if you have a popular app that people like and download in great numbers, why not put a price tag on it? Why do it for free?

• Someone tell me why people writing GNU code use { like that?

  - by Deus Deceit

  I saw the rules on how to type code for UNITY project or GNU software in general. Why do they write code in such an ugly form? Is there a particular reason why they don't put brackets the way (from what I know) most people do? Why like this: for (i = 0; i < 5; i++) { //do something } and not like this: for (i = 0; i < 5; i++) { //Do something } or this: for(i = 0; i < 5l i++) { //Do Something } ???

• How would I get work as a PHP, MySQL Developer?

  - by Matthew

  I've been working with PHP and MySQL to create various projects that I've been interested in, I can design the user interface, and the back end programming. I've created simple social networking sites, book marking sites, and project management software. So what steps would I take to get a job? Is there a market for PHP, MySQL web developers? Is it possible to take instructions and work from home for someone? How would I accept payment? Should I start a company? or work for someone? I am currently based in South Africa, many of the companies are lacking the innovation that I'm seeking for in a company.

• What is Object Oriented Programming ill-suited for?

  - by LeguRi

  In Martin Fowler's book Refactoring, Fowler speaks of how when developers learn something new, they don't consider when it's inappropriate for the job: Ten years ago it was like that with objects. If someone asked me when not to use objects, it was hard to answer. [...] It was just that I didn't know what those limitations were, although I knew what the benefits were. Reading this, it occurred to me I don't know what the limitations or potential disadvantages of Object-Oriented Programming are. What are the limitations of Object Oriented Programming? When should one look at a project and think "OOP is not best suited for this"?

• Which is more secure: Tomcat standalone or Tomcat behind Apache?

  - by NoozNooz42

  This question is not about performance, nor about load-balancing, etc. Which would be more secure: running Tomcat in standalone mode or running Tomcat behind apache? The thing is, Tomcat is written in Java and hence it is pretty much immune to buffer overrun/overflow (unless a buffer overrun in a C-written lib used by Tomcat can be triggered, but they're rare [the last I remember was in zlib, many many moons ago] and one heck of a hack to actually exploit), which gets rid of a lot of potential exploits. This page: http://wiki.apache.org/tomcat/FAQ/Security has this to say: There have been no public cases of damage done to a company, organization, or individual due to a Tomcat security issue... there have been only theoretical vulnerabilities found. All of those were addressed even though there were no documented cases of actual exploitation of these vulnerabilities. This, combined with the fact that buffer overrun/overflow are pretty much non-existent in Java, makes me believe that Tomcat in standalone mode is pretty secure. In addition to that, I can install both Java and Tomcat on Linux without needing to be root. The only moment I need to be root is to set up a transparent port 8080 to port 80 forwarding (and 8443 to 443). Two iptables line as root, that's all root is needed for. (I don't know for Apache). Apache is much more used than Tomcat and definitely does not have a security track record as good as Tomcat. What would make Tomcat + Apache more secure? What would make Tomcat + Apache less secure? In short: which is more secure, Tomcat standalone or Tomcat with Apache? (remembering that performance aren't an issue here)

• Active Directory Password Formats

  - by Brent Pabst

  Hi, I'm working on an open source project that will manage active directory users. I am looking for feedback from Windows/Active Directory Admins on the formats of usernames they prefer or their organization uses. I want to make sure the software allows admins to use the most popular formats when new users are created. Here is the list I have so far: 1. <firstname><lastname> 2. <lastname><firstname> 3. <lastname><firstinitial> 4. <lastname><firstinitial><middleinitial> 5. <firstinitial><lastname> 6. <firstinitial><middleinitial><lastname> 7. <firstname><lastinitial> In addition how do you handle multiple identical names? So if two John Smith's exist do you append a numeric number, or interject a middle initial or name to solve the problem? Thanks for the feedback

• Dealing with "I-am-cool-and-you-are-dumb" manager [closed]

  - by Software Guy

  I have been working with a software company for about 6 months now. I like the projects I work on there and I really like all the people there except for 1 guy. That guy is technically smart, and he is a co-founder of the company. He is an okay guy in person (the kind you wouldn't want to care about much) but things get tricky when he is your manager. In general I am all okay but there are times when I feel I am not being treated fairly: He doesn't give much thought to when he makes mistakes and when I do something similar, he is super critical. Recently he went as far as to say "I am not sure if I can trust you with this feature". The detais of this specific case are this: I was working on this feature, and I was already a couple of hours over my normal working hours, and then I decided to stop and continue tomorrow. We use git, and I like to commit changes locally and only push when I feel they are ready. This manager insists that I push all the changes to the central repo (in case my hard drive crashes). So I push the change, and the ticket is marked as "to be tested". Next day I come in, he sits next to me and starts complaining and says that I posted above. I really didn't know what to say, I tried to explain to him that the ticket is still being worked upon but he didn't seem to listen. He interrupts me in-between when I am coding, which I do not mind, but when I do that same, his face turns like this :| and reacts as if his work was super important and I am just wasting his time. He asks me to accumulate all questions, and then ask him altogether which is not always possible, as you need a clarification before you can continue on a feature implementation. And when I am coding, he talks on the phone with his customers next to me (when he can go to the meeting room with his laptop) and doesn't care. He made me switch to a whole new IDE (from Netbeans to a commercial IDE costing a lot of money) for a really tiny feature (which I later found out was in Netbeans as well!). I didn't make a big deal out of it as I am equally comfortable working with this new IDE, but I couldn't get the science behind his obsession. He said this feature makes sure that if any method is updated by a programmer, the IDE will turn the method name to red in places where it is used. I told him that I do not have a problem since I always search for method usage in the project and make sure its updated. IDEs even have refactoring features for exactly that, but... I recently implemented a feature for a project, and I was happy about it and considering him a senior, I asked him his comments about the implementation quality.. he thought long and hard, made a few funny faces, and when he couldn't find anything, he said "ummm, your program will crash if JS is disabled" - he was wrong, since I had made sure it would work fine with default values even if JS was disabled. I told him that and then he said "oh okay". BUT, the funny thing is, a few days back, he implemented something and I objected with "But that would not run if JS is disabled" and his response was "We don't have to care about people who disable JS" :-/ Once he asked me to investigate if there was a way to modify a CMS generated menu programmatically by extending the CMS, I did my research and told him that the only was is to inject a menu item using JavaScript / jQuery and his reaction was "ah that's ugly, and hacky, not acceptable" and two days later, I see that feature implemented in the same way as I had suggested. The point is, his reaction was not respectful at all, even if what I proposed was hacky, he should be respectful, that I know what's hacky and if I am suggesting something hacky, there must be a reason for it. There are plenty of other reasons / examples where I feel I am not being treated fairly. I want your advice as to what is it that I am doing wrong and how to deal with such a situation. The other guys in the team are actually very good people, and I do not want to leave the job either (although I could, if I want to). All I want is respect and equal treatment. I have thought about talking to this guy in a face to face meeting, but that worries me that his attitude might get worse and make things more difficult for me (since he doesn't seem to be the guy who thinks he can be wrong too). I am also considering talking to the other co-founder but I am not sure how he will take it (as both founders have been friends forever). Thanks for reading the long message, I really appreciate your help.
