• How to stop gold-plating and just be content to release working developments

  - by Andy Bowskill

  The development team that I'm a member of has recently adapted to work according to Agile practices. This has personally highlighted the fact that I can't stop myself gold-plating code (and documentation) and I consequently exceed original estimates, when I could've delivered solutions that meet the requirements much earlier. I think my ethic is bordering on the obsessive in that I become too attached to my code and am rarely content to release before I've refactored and perfected it to the nth degree. I am happy that I have realised this but how can I change my attitude/mentality to be content with my progress and release on-time instead?

• JCP.Next Progress Updates

  - by heathervc

  JSR 355, JCP Executive Committee Merge, is currently nearing the end of the Public Review period.  Review the current draft here and provide feedback here.  The review closes on 12 June 2012.  The JCP Executive Committee met face to face in Sao Paulo, Brazil earlier in May, and has published a revision (version 2.1) of the EC Standing Rules.  The EC Standing Rules were introduced in October 2011 with the launch of JCP version 2.8 (JSR 348).  Version 2.1 of the EC Standing Rules will modify rules for attendance at EC face-to-face meetings. Remote observers will be permitted in "read-only" mode but unless a member attends in person they will be counted as absent.  The review period for these changes will close on June 30 2012.  Please comment on the proposed changes by logging an issue in the JCP EC issue tracker.

• Profiling and containing memory per system

  - by chadb

  I have been interesting in profiling and keeping a managed memory pool for each subsystem, so I could get statistic on how much memory was being used in something such as sounds or graphics. However, what is the best design for doing this? I was thinking of using multiple allocators and just using one per subsystem, however, that would result in global variables for my allocators (or so it would seem to me). Another approach I have seen/been suggested is to just overload new and pass in an allocator for a parameter. I had a similar question over on stackoverflow here with a bounty, however, it seems as if perhaps I was too vague or just there is not enough people with knowledge in the subject.

• Debugging-Setting Consoles in Games

  - by ShrimpCrackers

  Right now I have the graphical and input portions of a console for my game (command parsing hasn't been implemented yet). I was wondering how you would go about making changes to properties in game objects. For example, if I typed in the console: skeletonMonster maxHP 20 That would change all of the existing in-game skeletons' max hit points to 20. After you parse this information what are some ways to change the value? How can I change the variable(s) without violating information hiding? I'd like to implement this so I don't have to change variables in the code and recompile every time while playtesting.

• Programming Challenges for a beginner

  - by JMK

  I'm in an unusual situation. A colleague of mine wants to "learn programming" and, being a developer I have been tasked with teaching him "programming". Personally, I am self taught, and have never taught any sort of skill to anybody else before so I am not quite sure where to start. Also, I still have a heck of a lot to learn myself (although don't we all)! I write in C# but is C# a good language for a beginner? I was thinking that Visual Basic .Net would be a better starting point, so was considering getting him setup with Visual Studio Express 2010, teaching him a few basics (variables, functions, classes etc) then finding some programming challenges and asking him to work through these. Does anybody have a good source of these sorts of challenges? Also is this a good strategy? Finally, what are your experiences of teaching programming to somebody else and what advice would you give?

• T-SQL Tuesday #36 (#tsql2sday)– Post-PASS Summit Depression

  - by Argenis

  I had an email thread going with a prominent member of the SQL Server community today, where he confessed that he didn’t attend any sessions during the PASS Summit last week. He spent all of this time networking and catching up with people. I, personally, can relate. This year’s Summit was another incarnation of that ritual of SQL Server professionals meeting to share their knowledge, experience, and just have a wonderful time while doing so. It’s been a few days after the Summit is over, and I’m definitely dealing with withdrawal. My name is Argenis, and I’m a #SQLFamilyHolic.         (This post is part of the T-SQL Tuesday series, a monthly series of blog posts from members of the SQL Server community – this month, Chris Yates is hosting)

• String Formatting with concatenation or substitution

  - by Davio

  This is a question about preferences. Assume a programming language offers these two options to make a string with some variables: "Hello, my name is ". name ." and I'm ". age ." years old." StringFormat("Hello, my name is $0 and I'm $1 years old.", name, age) Which do you prefer and why? I have found myself using both without any clear reason to pick either. Considering micro-optimizations is not within the scope of this question. Localization has been mentioned as a reason to go with option #2 and I think it's a very valid reason and deserves to be mentioned here. However, would opinions differ based on aesthetic viewpoints?

• Best way of accessing data on different pages

  - by Gaz83

  I'm looking for a way to load data into properties/variables etc and have this information accessible to all the pages of my app. I want the information to be loaded via a background thread to keep UI thread free. Some of the pages will have various properties of their controls binding to these global properties. Here is what I tried. Created a static class. All pages could access the data but can't bind. Changed the static class to a Singleton and used DependencyProperty's. All pages could access data and binding worked fine but cross-threading issues when accessing via background threads. I have read in various places on this subject but haven't really come up with the best method yet for my situation.

• Cloud computing cost savings for large enterprise

  - by user13817

  I'm trying to understand whether cloud computing is meant for small to medium sized companies OR also for large companies. Imagine a website with a very large user base. The storage and bandwidth demands as well as the number of database transactions are incredibly high. The website might be hosting videos, music, images, etc. that keep the demands high. Does it make sense to be in the cloud when you know you need huge volumes of storage, bandwidth, and GET,PUT,etc. requests? (Each of these variables costs money in the cloud) OR does it make sense to build your own infrastructure? I can see the cost savings of cloud computing if you are a small business, but if you were aiming at the next big thing on the Internet, I can't quite see the benefits.

• Instructions on Installing the FreeNX server on Ubuntu Karmic (9.10) are incorrect

  - by Bob Free

  How does one fix (or report an error) on an 'immutable' help.ubuntu.community wiki page? I am a registered member of the wiki. On http://help.ubuntu.com/community/FreeNX under the section: Installing the FreeNX server on Ubuntu Karmic (9.10) and higher, step #2, bjorn-nostvold erroneously changed on 2013-01-24 "add-apt-repository" to "apt-add-repository". The original "add-apt-repository" is correct - at least on my Karmic (9.10) version of Ubuntu. By the number of confused people I've found via google search, this seems to be throwing off a lot of people, myself included.

• How to obtain window handle in SDL 2.0.3

  - by Diorthotis

  I need to obtain the handle of the window for SDL 2.0.3. I got the suggestion to use info.window after initializing SDL and filling the info variable with data by calling SDL_GetWindowWMInfo(); included in the header file SDL_syswm.h. My compiler (visual studio 2008 professional edition) gives the following error: 226) : error C2039: 'window' : is not a member of 'SDL_SysWMinfo' 1 include\sdl_syswm.h(173) : see declaration of 'SDL_SysWMinfo' Any help appreciated. Thanks. Nevermind, I needed to use "info.info.win.window". That seems a bit redundant, but whateves.

• Class Versus Struct

  - by Prometheus87

  In C++ and other influenced languages there is a construct called Structure (struct) and we all know the class. Both are capable of holding functions and variables. some differences are 1. Class is given memory in heap and struct is given memory in stack 2. in class variable are private by default and in struct thy are public My question is that struct was somehow abandoned for Class. Why? other that abstraction, a struct can do all the same stuff a class does. Then why abandon it?

• Zooming to point of interest

  - by user1010005

  I have the following variables: Point of interest which is the position(x,y) in pixels of the place to focus. Screen width,height which are the dimensions of the window. Zoom level which sets the zoom level of the camera. And this is the code I have so far. void Zoom(int pointOfInterestX,int pointOfInterstY,int screenWidth, int screenHeight,int zoomLevel) { glTranslatef( (pointOfInterestX/2 - screenWidth/2), (pointOfInterestY/2 - screenHeight/2),0); glScalef(zoomLevel,zoomLevel,zoomLevel); } And I want to do zoom in/out but keep the point of interest in the middle of the screen. but so far all of my attempts have failed and I would like to ask for some help.

• Why do most of us use 'i' as a loop counter variable?

  - by kprobst

  Has anyone thought about why so many of us repeat this same pattern using the same variable names? for (int i = 0; i < foo; i++) { // ... } It seems most code I've ever looked at uses i, j, k and so on as iteration variables. I suppose I picked that up from somewhere, but I wonder why this is so prevalent in software development. Is it something we all picked up from C or something like that? Just an itch I've had for a while in the back of my head.

• Using MLP, how to make a link to the according page in the other languages?

  - by lyle

  Hi all, the question says it all, but here's a bit more detail: I help building a bilingual website using MLP on TextPattern. It's trivial to put a link to the top level page of another language, but how to put a link to the current page in another language? Eg. /en/contact should link to /de/kontakt (the same article in another language). I'm sure there are some variables somewhere that I could put into the template that would be filled with the correct links. Thankx in advance. :)

• Would it be possible to build a client portal on Squarespace6?

  - by aBathologist

  I'm helping a family member set up a site which will need to include a secure client portal, providing access to documents and a simple database. I have been encouraging them to go with a more established, open source CSM like drupal or joomla, whose capability in this area is evident. However, they have a strong preference for Squarespace. Does any one know if it would be possible to accomplish this with the new developer platform for squarespace 6? I've spent well over an hour searching google, the squarespace site and stackexchange, but can't seem to find any clear answer to this question. I'm grateful for any insight you all can provide.
