  • 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?

  • Learning PHP from beginner to advanced

    - by Liam
    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!

  • 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)

  • Domain name made of keywords redirecting to main website's page

    - by ivanivan
    Let's say I have a website called books.com where I sell books. I've read on Redirecting different domains to your main site that it's not a bad idea to register another domain that does a 301 redirect to my website, like booksforsale.com. Now, say I want to only target a specific category withing my website, like books.com/sci-fi/ so I register sci-fi-books.com and do a 301 redirect. Would this improve my search rankings? Thanks.

  • What should a Python developer know while learning Ruby?

    - by C J
    I have been a Python programmer for about 18 months, consisting of one internship and a few side projects, and I consider myself pretty comfortable in the language. However, there seems to be a lot of attention on Ruby in the programming field, but not a lot on Python anymore. So in learning Ruby, are there going to be Pythonic things that are just bad practices in Ruby? What should I watch out for, and what should I avoid?

  • Is it dangerous for me to give some of my Model classes Control-like methods?

    - by Pureferret
    In my personal project I have tried to stick to MVC, but I've also been made aware that sticking to MVC too tightly can be a bad thing as it makes writing awkward and forces the flow of the program in odd ways (i.e. some simple functions can be performed by something that normally wouldn't, and avoid MVC related overheads). So I'm beginning to feel justified in this compromise: I have some 'manager programs' that 'own' data and have some way to manipulate it, as such I think they'd count as both part of the model, and part of the control, and to me this feels more natural than keepingthem separate. For instance: One of my Managers is the PlayerCharacterManager that has these methods: void buySkill(PlayerCharacter playerCharacter, Skill skill); void changeName(); void changeRole(); void restatCharacter(); void addCharacterToGame(); void createNewCharacter(); PlayerCharacter getPlayerCharacter(); List<PlayerCharacter> getPlayersCharacter(Player player); List<PlayerCharacter> getAllCharacters(); I hope the mothod names are transparent enough that they don't all need explaining. I've called it a manager because it will help manage all of the PlayerCharacter 'model' objects the code creates, and create and keep a map of these. I may also get it to store other information in the future. I plan to have another two similar classes for this sort of control, but I will orchestrate when and how this happens, and what to do with the returned data via a pure controller class. This splitting up control between informed managers and the controller, as opposed to operating just through a controller seems like it will simplify my code and make it flow more. My question is, is this a dangerous choice, in terms of making the code harder to follow/test/fix? Is this somethign established as good or bad or neutral? I oculdn't find anything similar except the idea of Actors but that's not quite why I'm trying to do. Edit: Perhaps an example is needed; I'm using the Controller to update the view and access the data, so when I click the 'Add new character to a player button' it'll call methods in the controller that then go and tell the PlayerCharacterManager class to create a new character instance, it'll call the PlayerManager class to add that new character to the player-character map, and then it'll add this information to the database, and tell the view to update any GUIs effected. That is the sort of 'control sequence' I'm hoping to create with these manager classes.

  • 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?

  • Test Preparation Materials

    - by GavinPayneUK
    I wrote an article on my personal blog a few weeks ago about my preparation for my first Microsoft exam, 70-432.  ( link )  Since then I’ve been reading and demo’ing all the relevant features of SQL Server in the hope that if I get questions on them I’ll be prepared. I’ve learnt a few things in the last couple of weeks, some good, some bad which I’ll now share. The first thing I found is that learning about how SQL Server works is fun and interesting, far better than spending an evening...(read more)

  • Is it possible to measure if someone is a 'good' programmer? [closed]

    - by Alex Angas
    Possible Duplicate: How Can I Know Whether I Am a Good Programmer? There are a number of questions here about recognising or considering someone as a good/bad programmer. These are all subjective. What I'd like to know is if there is a way to measure this. I realise there will and should be a subjective element to it. But is it also possible to have some actual numbers to back up (or contradict) such an assessment?

  • Programs and memory consumption [closed]

    - by cobie
    I have a 4gb ram macbook pro but I still run out of memory when I have chrome and a few other light weight applications open such as multiple windows of macvim. These programs are written in C/C++ so technically should be memory efficient but why do they suck up all these memory. is it just bad engineering or graphical user interfaces because I have read about incredible feats performed in software dev back in the early computing days with very limited memory but now it just feels like the applications expand to fill all my memory.

  • Best books on Managing a Software Development Team? [closed]

    - by JohnFx
    The canonical books on software development is fairly well established. However, after reading through a dreadful book full of bad advice on managing programming teams this weekend I am looking for recommendations for really good books that focus on the management side of programming (recruiting, performance measurement/management, motivation, best practices, organizational structure, etc.) and not as much on the construction of software itself. Any suggestions?

  • Why You Should Launch Your Own Web Directory

    One of the easiest types of web sites to launch is a link directory. Just download one of the free or inexpensive PHP software packages, install, configure, add some categories, add some links and you're off! Having your own directory isn't a bad idea, despite what some pundits might think, for a number of reasons which I'll outline.

  • Google Chrome (not chromium) is crashing XFCE on startup. Where can I find some detailed logs of the issue?

    - by MALON
    I'm using xubuntu 12.10 and every time I open Chrome, the desktop enviro crashes then automatically restarts, prompting me to log in again. This is the latest x86 .deb downloaded from Chrome's website. I've tried both installing the .deb using the software package manager and using sudo dpkg -i, same issue for both, except that the package manager puts out an alert that says "This package is of bad quality", but doing a quick google search reveals that particular message is a bug in Chrome and it's safe to ignore.

  • Ask temperature on ubuntu 11.10 too hot

    - by stacheldraht
    I wonder why when I am using Ubuntu, my laptop temperature increases. It's around 62 degrees or less. I am already using Jupiter and have set it to power saving mode but if I use maximum performance the temperature can reach 70 degrees or more. Its too hot if I compare it when I am running windows where the temperature is quite normal at 56 degrees. How can I solve that?, sorry for my bad English.
