    - by P.Brian.Mackey
    According to a popular SO post is it considered a bad practice to prefix table names. At my company every column is prefixed by a table name. This is difficult for me to read. I'm not sure the reason, but this naming is actually the company standard. I can't stand the naming convention, but I have no documentation to back up my reasoning. All…

  • Worst practices in C++, common mistakes ...

    - by Felix Dombek
    After reading this famous rant by Linus Torvalds, I wondered what actually are all the bad things programmers might do in C++. I'm explicitly not referring to typography errors or bad program flow as treated in this question and answers, but to more high-level errors which are not detected by the compiler and do not result in obvious bugs at first…

  • When to reply 400 Bad Request

    - by KajMagnus
    According to www.w3.org, a Web server should reply with status code 400 Bad Request if: "The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications" Does that mean only request that violates some HTTP spec? Or does it include a request that my particular Web…

  • How to learn PHP effectively?

    - by Goma
    A dozen of bad tutorials out there that teach you bad habits especially when we speak about PHP. I want to learn how to avoid the things that can lead me to develop inefficient web applications.

  • Are programmers bad testers?

    - by jhsowter
    I know this sounds a lot like other questions which have already being asked, but it is actually slightly different. It seems to be generally considered that programmers are not good at performing the role of testing an application. For example: Joel on Software - Top Five (Wrong) Reasons You Don't Have Testers (emphasis mine) Don't…

  • Bad 3D Performance in Ubuntu 12.04

    - by Pandem
    I already posted a question before but I didn't really get any advice/help. I'll be a bit more brief/general in hope it'll help. I have an MSI HD 7850 with the Catalyst 12.4 drivers installed. I've found that I'm having bad 3D performance for some reason but I'm not entirely sure what. I suspect it may just that the graphics…

  • Bad Performance With Games Under Wine in Ubuntu 12.04

    - by Pandem
    I'm somewhat new to Linux. I've dabbled with it before but never more than just experimentation in a VM or dual boot where I almost always reverted back to Windows soon after (more due to a lack of commitment than a dislike for the OS). Anyway my problem is that in the two games (Guild Wars and Team Fortress 2) I've tried so…

    - by TehGrumpyCoder
    There's lots of ways of having a bad day at work... I suppose for many people, just being *at* work makes it a bad day, but I happen to be one of those people that found a way to do something I like for a living. I've always said "if you're not having fun, what's the point?" ... on the latest Zune podcast, they were…

    - by user999
    I receive this message when trying to change my password: "Bad: new and old password are too similar" The passwords' "similarity" is irrelevant for my needs, so I'd like to bypass this. I tried sudo passwd $my_username I thought this had worked because I got a message: passwd: password updated successfully …
