• Why are there so many string classes in the face of std::string?

  - by fish

  It seems to me that many bigger C++ libraries end up creating their own string type. In the client code you either have to use the one from the library (QString, CString, fbstring etc., I'm sure anyone can name a few) or keep converting between the standard type and the one the library uses (which most of the time involves at least one copy). So, is there a particular misfeature or something wrong about std::string (just like auto_ptr semantics were bad)? Has it changed in C++11?

• Changing jobs and leaving a project without a leader (aka, me)

  - by AnonUntilAfterTheEvent

  I'm the lead on a project that has been underway for about a year and a half. Two of us have been working on it. One is the database guy. I'm the javascript/ui guy. Which is to say, essentially no overlap in code knowledge. Here's the thing. Someone is about to offer me a sweet job with a nearly 30% bump in pay. Though I am perfectly happy with my current job and love the project, the new one would be better and I can't imagine saying no. The big problem is that my project is supposed to go into production starting in a few weeks. I will consider the new guys to have disqualified the new job by being bad people who would ruin my life if they won't cooperate and let me start after deployment. Since they seem like decent, ethical people, I don't expect that to be a problem. The current project will be brutalized by my absence. I take some comfort in the fact that I have emphatically requested an understudy for at least six months. That puts a little of the responsibility on the boss's head, but still, it's going to be a really bad thing. What do others of you do when you are a critical to a project when it's time to move on? Do I owe any obligation to stick around even though something better shows up? I know my spouse would object if I found someone else. Does that apply to work? I do have an understudy now, though he's fresh out of college. He's not going to replace me anytime soon. It's a small shop and the boss is going to be crushed. I am traumatized in anticipation of telling him and feel guilty about the practical consequences. I'm looking for some solace and some strategy about how to deal with this transition. Thank you for listening. =========================Subsequent notes ========================= @ChaosPandion, Chance: No, I can't stay to finish the project. I will insist on a compromise where I finish the current sprint (about a month from now) but there is at least a half year, probably a year of solid, full-time, work still to be done. I wouldn't expect the new employer to hold the job that long.

• Oracle Enterprise Data Quality: A Leader in Customer Satisfaction

  - by Mala Narasimharajan

   It’s always good to hear feedback from practitioners – the ones who are in the trenches who have experienced both the good and the bad sides of enterprise software.   Gartner recently released a report which surveyed 260 data quality professionals from around the world and found that most expressed considerable satisfaction as a whole from their data quality tool vendors.  However, a couple of key findings stand out which include, Datanomic (acquired by Oracle), leading the pack in terms of overall customer satisfaction among data quality tools.  Read all about it right here http://bit.ly/Ay45SG

• Keep coding the wrong way to remain consistent? [closed]

  - by bwalk2895

  Possible Duplicate: Code maintenance: keeping a bad pattern when extending new code for being consistent, or not? To keep things simple let's say I am responsible for maintaining two applications, AwesomeApp and BadApp (I am responsible for more and no that is not their actual names). AwesomeApp is a greenfield project I have been working on with other members on my team. It was coded using all the fancy buzzwords, Multilayer, SOA, SOLID, TDD, and so on. It represents the direction we want to go as a team. BadApp is a application that has been around for a long time. The architecture suffers from many sins, namely everything is tightly coupled together and it is not uncommon to get a circular dependency error from the compiler, it is almost impossible to unit test, large classes, duplicate code, and so on. We have a plan to rewrite the application following the standards established by AwesomeApp, but that won't happen for a while. I have to go into BadApp and fix a bug, but after spending months coding what I consider correctly, I really don't want do continue perpetuate bad coding practices. However, the way AwesomeApp is coded is vastly different from the way BadApp is coded. I fear implementing the "correct" way would cause confusion for other developers who have to maintain the application. Question: Is it better to keep coding the wrong way to remain consistent with the rest of the code in the application (knowing it will be replaced) or is it better to code the right way with an understanding it could cause confusion because it is so much different? To give you an example. There is a large class (1000+ lines) with several functions. One of the functions is to calculate a date based on an enumerated value. Currently the function handles all the various calculations. The function relies on no other functionality within the class. It is self contained. I want to break the function into smaller functions (at the very least) and put them into their own classes and hide those classes behind an interface (at the most) and use the factory pattern to instantiate the date classes. If I just broke it out into smaller functions within the class it would follow the existing coding standard. The extra steps are to start following some of the SOLID principles.

• Adobe Air Mobile AS3 app: challenges and how to overcome them?

  - by Arthur Wulf White

  I made a PC flash game for LD 26 - minimalism and I am working on porting it to Android. Some questions I'd like to ask: Is it bad to heavily use vector graphics (ie. this.graphics.lineTo()) in Mobile Air? Does Stencyl completely alleviate this issue? Are there any inherit disadvantages to using Air Mobile that I'm missing? Where is the documentation for Air mobile (I googled and found no recent books or documentation pdf so far)

• Through the Virtual Microscope–SQL Server and Hyper-V

  - by GavinPayneUK

  In my recent SQLBits conference session, Through the Virtual Looking Glass available to watch here , I spoke about monitoring SQL Server in a virtualised environment.  We looked at good and bad contention, where resource pressures which can adversely affect SQL Server might come from and most importantly how we can monitor the environment to detect them. Since then, I’ve been in discussions with some of the Microsoft product team who are focussed on optimising Windows 8 Hyper-V and SQL Server...(read more)

• Should I Use WordPress Category Archives or Regular Pages When Considering SEO?

  - by user1151640

  I've built a WordPress site based on posts and category archives (no pages). The menu redirects to different category archive pages that have a description, an image, and the relevant posts. Now that almost everything is finished I've started to worry and wonder if that was a good decision from an SEO standpoint Will Google consider category archives a bad idea for sitelinks compared to using regular pages?

• where does the discrepancy between \# in PS1 and n in !n come from?

  - by Cbhihe

  Something has been gnawing at me for a while now and I can't seem to find a relevant answer either in man pages or using your 'Don't be evil' search engine. My .bashrc has the following: shopt -s histappend HISTSIZE=100 HISTFILESIZE=0 # 200 previous value Putting HISTFILESIZE to 0 allows me to start with a clean history slate with each new term window. I find it practical in conjunction with using a prompt that contains \#, because when visualizing a previous command before recalling it with !n or !-p, one can just do: $ history | more to see its relevant "n" value In my case, usually the result of: $ \history | tail -1 | awk '{print $1}' # (I know this is an overkill, don't flame me) equals the expanded value of # in PS1 minus 1, which is how I like it to be at all times. But then, sometimes not. At times the expanded value of # sort of "runs away". It's incremented in such a a manner that it becomes than $(( $(\history | tail -1 | awk '{print $1}')+1 )) Any pointers, anyone?

• To canvas, or not to canvas, when building browser-based games?

  - by Letharion

  Background: I have extensive development background, but the last time I coded a game was many years ago. My Javascript skills are quite limited, and I intend to improve them by building a simple game — Tetris, Pac-man, or something of that complexity level. Question: It seems to me that a fundamental choice I need to make is whether I should render on a <canvas> element or not. With a canvas, I have basic tools for rendering points, lines, and more complex things on top of that. Presumably there are, or will be, also various frameworks to help with this. Without a canvas, I could keep my objects in the DOM-tree, like a regular webpage, only quite complex, with many overlapping elements. Is one approach better than the other? Are they mutually exclusive? How do I know which to pick?

• What is the correct way to use glTexCoordPointer?

  - by RubyKing

  I'm trying to work out how to use this function glTexCoordPointer. The man page states that I must set a pointer to the first element of the array that uses the texture cordinate. Here is my array: static const GLfloat GUIVertices[] = { //FIRST QUAD 1.0f, 1.0f, 0.0f, 1.0f, 1.0f, 0.0f, -1.0f, 1.0f, 0.0f, 1.0f, 0.0f, 0.0f, -1.0f, 0.94f, 0.0f, 1.0f, 0.0f, 1.0f, 1.0f, 0.94f, 0.0f, 1.0f, 1.0f, 1.0f, //2ND QUAD // x y z w X Y 1.0f, -1.0f, 0.0f, 1.0f, 1.0f, 0.0f, -1.0f, -1.0f, 0.0f, 1.0f, 0.0f, 0.0f, -1.0f, -0.94f, 0.0f, 1.0f, 0.0f, 1.0f, 1.0f, -0.94f, 0.0f, 1.0f, 1.0f, 1.0, }; But how do I set the pointer correctly for the fifth element on the 2nd quad first row? I was thinking something like this: glTexCoordPointer(1, GL_FLOAT, 6, reinterpret_cast<const GLvoid *>(29 * sizeof(float)));

• Upstart: sense of "stop on..." stanza when job is a task

  - by Binarus

  Hi, an upstart question (I think I have read all relevant man pages but could not find the answer there): What is the sense of using a "stop on ..." stanza in the definition of a job which is a task? The manuals tell us that such a job, after being started, just waits until its script (or exec stanza) is executed completely, and then stops automatically. Given that, what is the point in using "stop on ..." stanzas in such job definitions? For example, this is the job definition for Upstart's (very important) rc job in Natty 11.04 (leaving out comments and empty lines): start on runlevel [0123456] stop on runlevel [!$RUNLEVEL] export RUNLEVEL export PREVLEVEL console output env INIT_VERBOSE task exec /etc/init.d/rc $RUNLEVEL IMHO, the job, after being started by a runlevel event, will be stopped automatically as soon as /etc/init.d/rc $RUNLEVEL has finished. Thank you very much for any explanation!

• How to create/extract the EDID for/from a Monitor

  - by Luis Alvarado

  Is it possible to create or extract the Extended Display Identification Data (EDID) for/from a monitor. I have some issues with my monitor with the VGA and HDMI cables and I would like to test if by adding the EDID to the Nvidia Settings it could help in solve this issues. With the VGA cable I get a black out error and with the HDMI I get some EDID errors (bad EDID). So how can I create the EDID or extract it from the monitor by detecting its capabilities.

• Fun and Easy Ways to Get Backlinks

  The cat is out of the bag: The search algorithms place a fairly high degree of emphasis on the number of incoming links when determining a site's authority in the rankings. As a result, every SEO guru and would-be superstar blogger has started spamming the living daylights out of the rest of the web trying to build backlinks to their own sites. In itself, this is not necessarily a bad thing; in theory, it forces people to stop being so myopic.

• windows azure thoughts.

  - by foxjazz

  Well I had a relatively unpleasant exprience with Microsoft's new offerings when it comes to azure.And of course they deleted the forum trail.They don't want the consumer as a customer, expect to pay $200 - $250 or more a year for azure and that doesn't include a good email solution. This is for the smallest slice offering.If you want a simple website solution 1and1.com isn't a bad choice and it's less than $50 a year.

• PHP Drupal alternatives

  - by Quinma

  Based off answers to this question: Will I pick bad coding habits from PHP books? and many others it is a general consensus that PHP is not the most well suited language for web development anymore (if you are not completely knowledgeable about the language). I use Drupal and write custom modules in PHP, does this viewpoint of PHP being an ill fitted web coding language also apply to Drupal based PHP sites? I generally build community sites and intra-company sites, are there better means of building these than with PHP and drupal frameworks?

• Implenting ActiveRecord with inheritance?

  - by King

  I recently converted an old application that was using XML files as the data store to use SQL instead. To avoid a lot of changes I basically created ActiveRecord style classes that inherited from the original business objects. For example SomeClassRecord :SomeClass //ID Property //Save method I then used this new class in place of the other one, because of polymorphism I didn't need to change any methods that took SomeClass as a parameter. Would this be considered 'Bad'? What would be a better alternative?

We will soon launch our hiring process for programmers and we are mapping out what would be the best questions. I have read quite a few posts here that suggested on how to interview programmers but I haven't come across on what technical question to ask that non-technical recruiters can easily comprehend if the answer is good or bad.

• 3 SQL Join Concepts to Help You Choose the Right Join

  What do SQL joins and the "teach a man to fish" Chinese proverb have in common? SQL joins, like regular expressions, are one of those commonplace programming tasks in which true success is entirely dependent upon your ability to conceptualize the outcome. Fail to do so and you'll likely wind up spending a few hours in a frustrating round of trial and error.

• Learning PHP from beginner to advanced

  I've dabbled with PHP for a few years now and I'm capable of most of the basic things, building login forms etc but from my time on here I've noticed there's so much more I need to learn, like best practices, security issues etc and so I want to learn everything from the very basics. In the past I've used forums and browsed the web for snippets of code only I think this has led to my bad practices, can anybody recommend books or Valid, recommended learning sources? Thanks in advance!

• How to prioritize tasks when you have multiple programming projects running in parallel?

  - by Vinko Vrsalovic

  Say you have 5 customers, you develop 2 or 3 different projects for each. Each project has Xi tasks. Each project takes from 2 to 10 man weeks. Given that there are few resources, it is desired to minimize the management overhead. Two questions in this scenario: What tools would you use to prioritize the tasks and track their completion, while tending to minimize the overhead? What criteria would you take into consideration to determine which task to assign to the next available resource given that the primary objective is to increase throughput (more projects finished per time unit, this objective conflicts with starting one project and finishing it and then moving on to the next)? Ideas, management techniques, algorithms are welcome
