  • Five Indispensable MySQL Tools

    <b>Developer.com:</b> "Thanks to a number of well-designed tools, MySQL simply is a very easy database to "talk to," a convenience which is particularly important because developers often are tasked not only with constructing very complex schemas and queries, but also with monitoring overall server health and performance."

  • CouchDB basics for PHP developers

    <b>IBM Developerworks:</b> "If you're a typical PHP developer, it doesn't take a thorough review of past projects to pick out a telling pattern: In most (if not all) cases, you're probably getting PHP to talk to a database back end for all that dynamic data goodness; in 99 percent of those instances, you're using MySQL."

  • Where can I find some software development freelance/contract positions? [closed]

    - by m-y
    I currently have a full time job as a Microsoft.NET developer, but I'd like to supplement my income by doing some part-time freelance development work. Are there any websites (or other sources) out there that specialize in this? While the website (or other source) does not have to be geared specifically for part-time work or Microsoft.NET development, if it is than that would be just wonderful. The only thing I could find close to this was www.vworker.com which is not that great.

  • Should we persist with an employee still writing bad code after many years?

    - by user94986
    I've been assigned the task of managing developers for a well-established company. They have a single developer who specialises in all their C++ coding (since forever), but the quality of the work is abysmal. Code reviews and testing have revealed many problems, one of the worst being memory leaks. The developer has never tested his code for leaks, and I discovered that the applications could leak many MBs with only a minute of use. User's were reporting huge slowdowns, and his take was, "it's nothing to do with me - if they quit and restart, it's all good again." I've given him tools to detect and trace the leaks, and sat down with him for many hours to demonstrate how the tools are used, where the problems occur, and what to do to fix them. We're 6 months down the track, and I assigned him to write a new module. I reviewed it before it was integrated into our larger code base, and was dismayed to discover the same bad coding as before. The part that I find incomprehensible is that some of the coding is worse than amateurish. For example, he wanted a class (Foo) that could populate an object of another class (Bar). He decided that Foo would hold a reference to Bar, e.g.: class Foo { public: Foo(Bar& bar) : m_bar(bar) {} private: Bar& m_bar; }; But (for other reasons) he also needed a default constructor for Foo and, rather than question his initial design, he wrote this gem: Foo::Foo() : m_bar(*(new Bar)) {} So every time the default constructor is called, a Bar is leaked. To make matters worse, Foo allocates memory from the heap for 2 other objects, but he didn't write a destructor or copy constructor. So every allocation of Foo actually leaks 3 different objects, and you can imagine what happened when a Foo was copied. And - it only gets better - he repeated the same pattern on three other classes, so it isn't a one-off slip. The whole concept is wrong on so many levels. I would feel more understanding if this came from a total novice. But this guy has been doing this for many years and has had very focussed training and advice over the past few months. I realise he has been working without mentoring or peer reviews most of that time, but I'm beginning to feel he can't change. So my question is, would you persist with someone who is writing such obviously bad code?

  • Would you make use of "Google 20%" time if your employer encouraged and funded it?

    - by ChrisB
    We know about Google's 20% projects, whereby a developer can spend up to 20% of their time on a personal project which interests them. If your employer let you spend 20% of your time on a project that wasn't part of your day-to-day work, would you make use of it? I can think of a couple of reasons why not: It would make your normal work take 20% longer (extended deadline) You might want to keep your personal idea "personal."

  • How do professional application developers use version control systems, like GIT and Subversion?

    - by Wolfi
    I am a beginner developer and I have been wondering from the start, how do professional use tools like GIT and Subversion (I don't have a very good understanding about these tools), to fulfill their project's needs. If they do use it, how would I set up something like that? My applications are not so large and I am not working in a team yet, would they be of huge help to me? There are questions on this site about how to use the tools, but I need beginner support.

  • Is there a comprehensive list of the Ubuntu services for developers?

    - by tgm4883
    It seems every couple weeks I'm learning about a new service that can be used by developers to either A) get people involved, or B) make life easier for developers. Is there a list of all these services somewhere? Here are a few of them that I have recently found out about. https://errors.ubuntu.com/ http://harvest.ubuntu.com/ http://status.ubuntu.com/ :Edit: Found another. Although not strictly developer related, it's noteworthy https://apps.ubuntu.com

  • Trying to find resources to learn how to test software [closed]

    - by Davek804
    First off, yes this is a general question, and I'd be perfectly happy to move this to another portion of SE, but I didn't see a more fitting sub. Basically, I am hoping a more experienced QA tester can come along and really fill in some basics for me. So far, websites seem to be sparse in terms of explaining languages involved, basic practices, etc. So, I'm sorry in advance if this is too general, but towards the end of this post I ask some specific questions if it's just absolutely unacceptable to speak in general terms. I just landed a position as Junior Systems and QA Engineer with a social media startup. Their QA and testing is almost nonexistent, so if I do a good job, I imagine I'll find a lot of bugs and have a secure role in the business. I'm pretty good with the systems aspect of my role, but I need to learn more about the QA and testing aspects. We run hardware that's touchscreen based - the user can use and interact with the devices. So, in terms of my QA role, in the short term, I need to build scripts to test the hardware/software as a 'user' to try to uncover bugs. First off, what language should these scripts be written in? Does anyone have some examples? What about the longer term 'automated testing'? I'm familiar with regression testing as the developer adds in new features, sure, but the 50,000 other types of testing, not so much. Most of our hardware runs dotnet/C# code, with some of the servers running Java - but I don't expect to need to run tests on the Java side at this point. I hope to meet with one developer today and try to get a good idea of the output from the hardware so that I can 'mock' this data that gets sent to servers, to try to bugtest. Eventually, we will be moving the hardware to be closer to where I live and work, so that I can test virtually and on real hardware. So a lot of the bugs we're dealing with now are like this: the Local Server, which kiosks report their data to gets updated from the kiosks, but the remote server does not. Or, vis versa when the user registers on a kiosk, the remote server updates but the local server does not. But yeah, without much more detail, I imagine a lot of this info isn't helpful. I've bought a book "How Google Tests Software", but it's really a book more about 'how their software testing is different from Microsoft'. It doesn't teach how to test so much as why their methods are better. Does anyone have a good book that I can buy? An ebook maybe? My local Barnes and Noble kinda had a terrible selection. I also figure a book from 2005 is not necessarily that good either.
