  • MySQL & PHP: auto connect to DB or to properly way to pass host/db to MySQL methods

    - by SODA
    Hi, does anyone know of a known method in PHP to auto connect to MySQL db/table in case an app is using multiple databases on multiple hosts? Question 1: are there scripts around that allow to auto connect to necessary host/DB based on query? Question 2: if above is not possible, is there a known approach to properly passing host/DB info to make sure app is properly connected before executing the query?

  • Should HTML be encoded before being persisted?

    - by Sir Psycho
    Should HTML be encoded before being stored in say, a database? Or is it normal practice to encode on its way out to the browser? Should all my text based field lengths be quadrupled in the database to allow for extra storage? Looking for best practice rather than a solid yes or no :-)

  • How can i check if key is pressed during click event with jquery?

    - by daniel smith
    Hi, I would like to catch a click event with jquery and be able to tell if a key was pressed at the same time so i can fork within the callback function based on the keypress. for example: $("button").click(function() { if([KEYPRESSED WHILE CLICKED]) { do something... } else { do something different... } }); Does anyone know if this is possible at all or how it can be done if it is possible?

  • What .NET serializers have fixed size output for a given class?

    - by Jader Dias
    XML based serializers have variable size output for a given class. I can't use them to append data to my Memcached list, since I won't be able to retrieve that information later. But if I knew my serializer produced a fixed size output (N bytes), I could retrieve my data by splitting my list in N bytes chunks and then deserializing those chunks individually. I have created my own serializer for my class, but what other serializers I could use?

  • Does a lazy-programmer file auto-generator tags exist?

    - by Anthony Forloney
    I was wondering (if possible) if there was a program/tool/utility that when I create a new file and provide it with an extension that it creates the tags automatically? For example, a new file I create called index.php would have the appropriate tags auto-generated inside: <?php ?> I hope you get the idea. Does one, or could one, exist, preferably Windows based? Any information regarding this would be helpful.

  • CSS Multi-Column Forms in HTML/ASP.NET

    - by Caveatrob
    I've researched for hours and still haven't found a robust, non-absolute-positioning solution for displaying multiple-column forms and values without using TABLE tags. Can someone point me to a resource specifically oriented towards reproducing table-based, multiple-column forms (like name and address forms) in CSS to standards? Most of the forms I see only have a single column with field/value.

  • I simple search controller that stores search history, should I use resource routing or non-resource?

    - by vfilby
    I am learning rails and am toying with a simple web-app that integrates with flickr to search photos based on user given criteria and store the query in a search history table. I am seeking the best or 'rails' way of handling this. Should I setup a controller and non-resource routes that handle the search and store the data in a custom table; or should I create a resource for queries with a resource route and an additional path for search?

  • Implementing the server side of Webhooks

    - by Howiecamp
    If I want to Webhooks-enable a web application (I'm referring to the server-side of things, ie the server where the event happens and the callback is initiated from), are there libraries for this, or is this functionality typically part of the web server stack? Or, am I looking at this incorrectly, and to implement Webhooks I simply code my application to do an HTTP POST callback based on whatever events I care about?

  • R Package for Bayesian Belief Networks

    - by user187395
    Is anyone aware of an R package for Bayesian Belief Networks (BBN) that can handle latent (hidden) nodes? I am referring to process learning the structure and the parameters of the model. Based on the documentation, the "bnlearn" package does not provide for such capability. In addition, is anyone aware of R packages that allow for making inferences and sensitivity analysis for BBN? Thank you in advance.

  • How can I center something if I don't know ahead of time what the width is?

    - by zeckdude
    I am trying to center a paragraph tag with some text in it within a div, but I can't seem to center it using margin: 0 auto without having to specify a fixed width for the paragraph. I don't want to specify a fixed width, because I will have dynamic text coming into the paragraph tag and it will always be a different width based on how much text it is. Does anyone know how I can center the paragraph tag within the div without having to specify a fixed width for the paragraph or without using tables?

  • Slick: why would I save "Unit" to my database?

    - by alapeno
    I'm new to Scala and Slick and was surprised by something in the Slick documentation: The following primitive types are supported out of the box for JDBC-based databases in JdbcProfile ... Unit ... I don't get why this list contains Unit. From my understanding, Unit is similar to Java's void, something I neither can save to nor receive from my database. What is the intention behind it? edit: you can find it here.
