  • Are there any tutorial/guides to use firebug?

    - by ggfan
    I just got the add-on for firefox and it's awesome so far! But all I am doing is just moving the cursor around the page to get the css+html. And I know there are TONS more applications to firebug. Is there a beginner's guide to firebug since it's so popular or is it just something with practice?

  • Testing + production server and syncing MySQL data

    - by Matthew
    I have a web application running on LAMP with a testing server and a production server. Is there a standard practice for keeping the data on the testing server in sync with the production server? The data on the testing server gets out of date pretty quick and I feel like there must be an easier way than just dumping the production server and copying it onto the testing server every so often. It's not important that the data is in total sync, just that the testing server represents the production enviornment as accurately as possible.

  • PHP: Handling Multiple Submit Buttons

    - by sebb
    Would like to get a consensus as to what the best practice is in this scenario: Muliple submit buttons, is it better to handle this by having separate FORMS for each one of the submits, OR is it okay to have one form and check which button was pressed? thank you for your input :D

  • Where should I keep my log files?

    - by ripper234
    We keep most of our logs in a dedicated database table. We have written custom appenders for log4j and log4net, have a fixed log schema with lots of handy columns, and are quite happy with it. Is that the "best practice" (for sites smaller in scale than Facebook, where a simple DB table just won't scale)?

  • Retrieve remote XML data with PHP

    - by rrrfusco
    I'm currently reading a regularly updated XML file with PHP (simpleXML). I'd like to reduce calls to the remote server by reading a cache file on my web server, then after some time, retrieving a new copy of the remote file. Is this an accepted practice for reading remote XML files, then parsing? Can anyone offer some suggestions on how to go about this in PHP, or perhaps there are some PEAR classes that deal with this?

    - by vibneiro
    The original link of the problem is here: https://code.google.com/codejam/contest/90101/dashboard#s=p2&a=2 In simple words we need to find how many times the string S="welcome to code jam" appears as a sub-sequence of given string S, e.g. S="welcome to code jam" T="wweellccoommee to code qps jam" I know the theory but not good at DP in practice.

  • Using static variables in Android

    - by michael
    Hi, In android, are using static variables a recommended practice? E.g, implementing a Singleton pattern in Java, I usually do: private static A the_instance; public static A getInstance() { if (the_instance == null) { the_instance = new A(); } return the_instance; } Also, when does this get cleaned up by the Android JVM? Thank you.

  • Programmatically obtain DNS servers of host

    - by Nicholas Palko
    Using C++, I would like to obtain the DNS servers being used by a host for three operating systems: OS X, FreeBSD, and Windows. I'd like confirmation that the approaches below are indeed best practice, and if not, a superior alternative. OS X: already answered; updated link at developer.apple.com Windows: [GetNetworkParms](http://msdn.microsoft.com/en-us/library/aa365968(VS.85).aspx) FreeBSD: /etc/resolv.conf Thanks in advance for your help!

  • RESTfully request sub-parts of a representation be of a certain content-type

    - by Grayside
    I am requesting (via Accept: application/json) that an API I'm designing respond as JSON. However, I want the values within that JSON to be specified to conform to text/plain or text/html depending on the capabilities of the client. What is the RESTful best practice for a "sub-type"? How would this work if I formally switched to HAL as the top-level container? Accept: application/json+text/plain { "value": "Hello World" } Accept: application/json+text/html { "value": "<h2>Hello World</h2>" }

  • Bash: Is it ok to use same input file as output of a piped command?

    - by Amro
    Consider something like: cat file | command > file Is this good practice? Could this overwrite the input file as the same time as we are reading it, or is it always read first in memory then piped to second command? Obviously I can use temp files as intermediary step, but I'm just wondering.. t=$(mktemp) cat file | command > ${t} && mv ${t} file

    I was wondering if it's frowned upon to use the decorator module that comes with python. Should I be creating decorators using the original means or is it considered okay practice to use the module?

  • Is scala's cake pattern possible with parametrized components?

    - by Nicolas
    Parametrized components work well with the cake pattern as long as you are only interested in a unique component for each typed component's, example: trait AComponent[T] { val a:A[T] class A[T](implicit mf:Manifest[T]) { println(mf) } } class App extends AComponent[Int] { val a = new A[Int]() } new App Now my application requires me to inject an A[Int] and an A[String], obviously scala's type system doesn't allow me to extends AComponent twice. What is the common practice in this situation ?

  • Do most shared hosts handle gzipped files?

    - by Matrym
    I get them theoretically, but I'm grappling with gzipping files in practice. How should I go about gzip compressing my files, and what needs to be done in order to use them on a shared host? Would the following work? RewriteEngine On RewriteBase / RewriteCond %{HTTP:Accept-Encoding} .*gzip.* RewriteRule ^/(.*)\.js$ /$1.js.gz [L] RewriteRule ^/(.*)\.css$ /$1.css.gz [L] AddEncoding x-gzip text.gz

  • Having duplicate enumerator values

    - by whirlwin
    I'm creating a Tetris clone in C++, and I have an enum GameProperty, which is specified as follows: enum GameProperty { NUM_OF_TETROMINOES = 7, NUM_OF_TILES = 4, TETROMINO_ROTATIONS = 4 }; In my case, I only use these values when looping through a tetromino's tiles, e.g: for (int i = 0; i < TETROMINO_TILES; i++) { } Is it under any circumstance considered bad practice to have multiple enumerators with the same value?

  • Accessing Subversion commit data externally

    - by gaoshan88
    I have need to access subversion data (commit messages, files updated, revision numbers, dates modified, author, etc.) externally. Is this something for some sort of subversion hook or is there a decent third party package for this or some other "best practice" way to approach accessing subversion data externally (and by external I mean from a php/ruby or python script... external to subversion itself)?
