  • How do I design this link table?

    - by Soo
    Ok SO, I have a user table and want to define groups of users together. The best solution I have for this is to create three database tables as follows: UserTable user_id user_name UserGroupLink group_id member_id GroupInfo group_id group_name This method keeps the member and group information separate. This is just my way of thinking. Is there a better way to do this? Also, what is a good naming convention for tables that link two other tables?

  • CSS: What is the proper way to deal with multiple classes of Text

    - by DavidR
    So I'm on commission for a website, and I'm trying to improve my code. When dealing with a website with multiple types of font (here it's large, there it's small, there it's bold, here it's underlined, etc.) is this where we use the h1-h6, or do we reserve those for times when there is a definite hierarchy, using instead <p class="xxx"> to define different classes for text?

  • What are some lesser known usages of #pragma?

    - by Xavier Ho
    I've never understood the need of #pragma once when #ifndef #define #endif always works. I've seen the usage of #pragma comment to link with other files , but setting up the compiler settings was easier with an IDE. What are some other usages of #pragma that is useful, but not widely known?

  • JSDoc3: How to document a AMD module that returns a function

    - by Jens Simon
    I'm trying to find a way to document AMD modules using JSDoc3. /** * Module description. * * @module path/to/module */ define(['jquery', 'underscore'], function (jQuery, _) { /** * @param {string} foo Foo-Description * @param {object} bar Bar-Description */ return function (foo, bar) { // insert code here }; }); Sadly none of the patterns listed on http://usejsdoc.org/howto-commonjs-modules.html work for me. How can I generate a proper documentation that lists the parameters and return value of the function exported by the module?

  • PostgreSQL, triggers, and concurrency to enforce a temporal key

    - by Hobbes
    I want to define a trigger in PostgreSQL to check that the inserted row, on a generic table, has the the property: "no other row exists with the same key in the same valid time" (the keys are sequenced keys). In fact, I has already implemented it. But since the trigger has to scan the entire table, now i'm wondering: is there a need for a table-level lock? Or this is managed someway by the PostgreSQL itself?

  • buffer size for socket connection in c++

    - by wyatt
    I'm trying to build a basic POP3 mail client in C/++, but I've run into a bit of an issue. Since you have to define the buffer size when building the program, but a message can be arbitrarily large, how do you, say, get the mail server to send it to you in parts? And if this isn't the correct means of solving the problem, what is? And while I'm here, can anyone confirm for me that RFC 2822 is still the current document defining email layout? Thanks
