  • Where to store site settings: DB? XML? CONFIG? CLASS FILES?

    - by Emin
    I am re-building a news portal of which already have a large number of visits every day. One of the major concerns when re-building this site was to maximize performance and speed. Having said this, we have done many things from caching, to all sort of other measures to ensure speed. Now towards the end of the project, I am having a dilemma of where to store my site settings that would least affect performance. The site settings will include things such as: Domain, DefaultImgPath, Google Analytics code, default emails of editors as well as more dynamic design/display feature settings such as the background color of specific DIVs and default color for links etc.. As far as I know, I have 4 choices in storing all these info. Database: Storing general settings in the DB and caching them may be a solution however, I want to limit the access to the database for only necessary and essential functions of the project which generally are insert/update/delete news items, author articles etc.. XML: I can store these settings in an XML file but I have not done this sort of thing before so I don't know what kind of problems -if any- I might face in the future. CONFIG: I can also store these settings in web.config CLASS FILE: I can hard code all these settings in a SiteSettings class, but since the site admin himself will be able to edit these settings, It may not be the best solution. Currently, I am more close to choosing web.config but letting people fiddle with it too often is something I do not want. E.g. if somehow, I miss out a validation for something and it breaks the web.config, the whole site will go down. My concern basically is that, I cannot forsee any possible consequences of using any of the methods above (or is there any other?), I was hoping to get this question over to more experienced people out here who hopefully help make my decision.

  • Slow form submission.

    - by Tony
    When I submit a form, I can see my browser's progress bar slowly increased, it takes 4-6s to submit a form. It was a generic form like : <form id="someid" name="someName" action="someAction.do"> ... </form> I test it in IE8 and Firefox 3,both are very slow. My network condition is fine, my server works great. What could be the problem?

  • Using psexec to start Internet Explorer then navigate to a particular URL

    - by UnclePaulie
    Just like the question says, I want to be able to use psexec to start Internet Explorer, then load a particular website in the browser. I know how to start IE, just can't make a command that goes to a particular webpage. This is what I have so far: psexec "C:\program files\Internet Explorer\iexplore.exe" I just can't figure the syntax for loading anything other than the default start page Thanks!

  • Unicode characters and IE

    - by findmeahamper
    I just built a site that relies on certain Unicode characters like &#9398;, but have just realized that IE doesn't show these characters? Is there some meta tag to get the browser to show it or how do you update IE to handle these Unicode characters?

  • Random <hr/> that I don't know how to get rid of!

    - by Anonymous the Great
    There is no extra <hr/> on the page, and I cannot figure out why it is there. Do you see anything that is causing it? I am sorry for posting the whole thing, I do not know exactly where it starts. The <hr/> is at the top somewhere, but I'm not sure where. <?php print "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <font face="Segoe UI"> <body> <script type="text/javascript"> /*function detectBrowser() { var browser = navigator.appCodeName; if (browser!="Mozilla") {document.location.href="noaccess.php"; alert(browser);} } detectBrowser(); */ </script> <title>Second</title> <link rel="stylesheet" type="text/css" href="allCSS.css"/> <center> <!--<img align="right" src="logo.png" id="headerimg"/>--> <input type="image" id="headerimg" src="logo.png" align="right" onclick="toggleh();"/> <ul align="center" class=""> <div class="menu"> <ul class="nav"> <li><strong><a href="index.php">Home</a></strong> <ul> <li><a href="games.php">Games</a></li> <li><a href="browse.php">Browse</a></li> <li><a href="catalogue.php">Catalogue</a></li> <li><a href="forum.php">Forums</a></li> </ul> </li> <li><strong><a href="games">Games</a></strong> <ul> <li><a href="profile.php">Profile</a></li> <li><a href="settings.php">Settings</a></li> </ul> </li> <li><strong><a href="contact">Contact</a></strong> <ul> <li><a href="contact/index.php">Phone</a></li> <li><a href="contact/index.php">Email</a></li> <li><a href="contact/index.php">Mail</a></li> </ul> </li> </div> </center> </body> <center> <?php echo '<div id="msg">'; include 'message.txt'; echo '</div>'; //include 'hits.txt'; ?> <p> <?php function ChangeText($txt) { $txt='<script type="text/javascript">get();</script>'; echo '<script type="text/javascript">change();</script>'; $filename="message.txt"; $fp=fopen($filename,'w'); fwrite($fp,'<h4 class="hmsg">' . $txt .

  • Update Options on Existing jQuery Object

    - by Vince Kronlein
    I'm using Bootstrap and DataTables in my app and I have a default initializer for tables based on class. I can just add the class data-table to the table and it gets instantiated with the default values I want. I'd like to know how to change or update specific options based on a specific table. if ($.fn.dataTable) { $('.data-table').dataTable( { sDom: "R<'row'<'span6'l><'span6'f>r>t<'row'<'span6'i><'span6'p>>", sPaginationType: "bootstrap", oLanguage: { "sLengthMenu": "_MENU_ &nbsp; records per page" }, aoColumnDefs: [ { "bSortable": false, "aTargets": [ 0 ] } ] }); } All my data tables have a checkbox in the first column so the above removal of sorting works for all of them. But I'd like to be able to update the aoColumnDefs on a table by table basis so I can add other columns that I don't want sorted. So let's say I have a table: $('#member-list'), how do I access this object and update it's datatables options in jQuery? I can't find any reference or help anywhere. Thanks a lot! -V

  • ASP.net canvas server control

    - by Pierreten
    I was wondering if anyone has come up with an ASP.net server tag for the HTML5 canvas? I was thinking of something where I could declaritively define paths, curves; etc in the aspx markup, and the control would deliver the js to do this (perhaps with support for browser detection, and delivery of an emulation script for IE browsers.) Maybe a good idea for a Codeplex project for me to start up?

  • how to Solve the "Digg" problem in MongoDB

    - by user193116
    A while back,a Digg developer had posted this blog ,"http://about.digg.com/blog/looking-future-cassandra", where the he described one of the issues that were not optimally solved in MySQL. This was cited as one of the reasons for their move to Cassandra. I have been playing with MongoDB and I would like to understand how to implement the MongoDB collections for this problem From the article, the schema for this information in MySQL : CREATE TABLE Diggs ( id INT(11), itemid INT(11), userid INT(11), digdate DATETIME, PRIMARY KEY (id), KEY user (userid), KEY item (itemid) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; CREATE TABLE Friends ( id INT(10) AUTO_INCREMENT, userid INT(10), username VARCHAR(15), friendid INT(10), friendname VARCHAR(15), mutual TINYINT(1), date_created DATETIME, PRIMARY KEY (id), UNIQUE KEY Friend_unique (userid,friendid), KEY Friend_friend (friendid) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; This problem is ubiquitous in social networking scenario implementation. People befriend a lot of people and they in turn digg a lot of things. Quickly showing a user what his/her friends are up to is very critical. I understand that several blogs have since then provided a pure RDBMs solution with indexes for this issue; however I am curious as to how this could be solved in MongoDB.

  • jQuery plugin to wrap text around images + support IE6

    - by Alex
    This is a tall order, but is there a jQuery or Mootools (or other framework) plugin to wrap text around images and support IE6? I've tried the jQSlickWrap, but unless the browser supports HTML 5, you're out of luck. What's strange is that IE 6 supports the jQuery Background Canvas plugin, which uses the CANVAS object (via excanvas.js) just as this plugin does. Thanks.

  • Unresolved external symbol error in c++

    - by Crystal
    I am trying to do a simple hw problem involving namespace, static data members and functions. I am getting an unresolved external symbol error Error 1 error LNK2001: unresolved external symbol "private: static double JWong::SavingsAccount::annualInterestRate" (?annualInterestRate@SavingsAccount@JWong@@0NA) SavingsAccount.obj SavingsAccount And I don't see why I am getting this error. Maybe I don't know something about static variables compared to regular data members that is causing this error. Here is my code: SavingsAccount.h file #ifndef JWONG_SAVINGSACCOUNT_H #define JWONG_SAVINGSACCOUNT_H namespace JWong { class SavingsAccount { public: // default constructor SavingsAccount(); // constructor SavingsAccount(double savingsBalance); double getSavingsBalance(); void setSavingsBalance(double savingsBalance); double calculateMonthlyInterest(); // static functions static void modifyInterestRate(double newInterestRate); static double getAnnualInterestRest(); private: double savingsBalance; // static members static double annualInterestRate; }; } #endif SavingsAccount.cpp file #include <iostream> #include "SavingsAccount.h" // default constructor, set savingsBalance to 0 JWong::SavingsAccount::SavingsAccount() : savingsBalance(0) {} // constructor JWong::SavingsAccount::SavingsAccount(double savingsBalance) : savingsBalance(savingsBalance) {} double JWong::SavingsAccount::getSavingsBalance() { return savingsBalance; } void JWong::SavingsAccount::setSavingsBalance(double savingsBalance) { this->savingsBalance = savingsBalance; } // returns monthly interest and sets savingsBalance to new amount double JWong::SavingsAccount::calculateMonthlyInterest() { double monthlyInterest = savingsBalance * SavingsAccount::annualInterestRate / 12; setSavingsBalance(savingsBalance + monthlyInterest); return monthlyInterest; } void JWong::SavingsAccount::modifyInterestRate(double newInterestRate) { SavingsAccount::annualInterestRate = newInterestRate; } double JWong::SavingsAccount::getAnnualInterestRest() { return SavingsAccount::annualInterestRate; }

  • get rid of red X in IE for non-existing images

    - by hubertg
    I have a 3rd website (Confluence) which references images which are secured by a login. If the current user is logged in the image is shown if not the image url would redirect to a login form. Example When you enter this url in the browser a redirect to the login page is done. The problem now: IE shows a the dreaded red X icon for the image even though there should be just nothing (like in Firefox). Anyone knows how to get around this?

  • Exception when creating an activity: Could not select item Parcel unable to marshal value

    - by user341652
    Hi, I am trying to call an Activity from another instance of the activity. The code is supposed to be a simple file browser (part of a larger application). I am using a ListActivity, and when an item (such as a folder) is selected, it is supposed to open it up in the new Activity. I have a feeling it is a problem with the AndroidManifest (which just has the basic tag). Any assistance would be appreciated. Thanks, Steve

  • MySQL Paritioning performance

    - by Imran Pathan
    Measured performance on key partitioned tables and normal tables separately. But we couldn't find any performance improvement with partitioning. Queries are pruned. Using MySQL 5.1.47 on RHEL 4. Table details: UserUsage - Will have entries for user mobile number and data usage for each date. Mobile number and Date as PRI KEY. UserProfile - Queries prev table and stores summary for each mobile number. Mobile number PRI KEY. CREATE TABLE `UserUsage` ( `Msisdn` decimal(20,0) NOT NULL, `Date` date NOT NULL, . . PRIMARY KEY USING BTREE (`Msisdn`,`Date`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 PARTITION BY KEY(Msisdn) PARTITIONS 50; CREATE TABLE `UserProfile` ( `Msisdn` decimal(20,0) NOT NULL, . . PRIMARY KEY (`Msisdn`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 PARTITION BY KEY(Msisdn) PARTITIONS 50; Second table is updated by query select and order by date in first table in a perl program, query is select * from UserUsage where Msisdn=number order by Date desc limit 7 [Process data in perl] update UserProfile values(....) where Msisdn=number explain partition for select, shows row being scanned in a particular partition only. Is something wrong with partition design or queries as partitioning is taking almost same or more time compared to normal tables?

However, when I right click on the project node and select Test RESTful Web Service, the browser pop up, and supposedly my project would be listed on the left, and supposedly I would be able to select it, and test against various function that listed on the right. However, I dont see any of that. Any idea why?

  • Getting the first of a GROUP BY clause in SQL

    - by Michael Bleigh
    I'm trying to implement single-column regionalization for a Rails application and I'm running into some major headaches with a complex SQL need. For this system, a region can be represented by a country code (e.g. us) a continent code that is uppercase (e.g. NA) or it can be NULL indicating the "default" information. I need to group these items by some relevant information such as a foreign key (we'll call it external_id). Given a country and its continent, I need to be able to select only the most specific region available. So if records exist with the country code, I select them. If, not I want a records with the continent code. If not that, I want records with a NULL code so I can receive the default values. So far I've figured that I may be able to use a generated CASE statement to get an arbitrary sort order. Something like this: SELECT *, CASE region WHEN 'us' THEN 1 WHEN 'NA' THEN 2 ELSE 3 END AS region_sort FROM my_table WHERE region IN ('us','NA') OR region IS NULL GROUP BY external_id ORDER BY region_sort The problem is that without an aggregate function the actual data returned by the GROUP BY for a given row seems to be untameable. How can I massage this query to make it return only the first record of the region_sort ordered groups?

  • PHP Beginner: How to pass PHP variable from one PHP code segment to another ?

    - by Misha Moroshko
    I have index.php which uploads a file to server and sets several PHP variables (like $target_folder_and_file_name). index.php also has the following line (it was originally index.html): <script language="JavaScript" src="main.js.php"></script> After index.php returned to the browser, the browsers asks for main.js.php from the server (right?). Can I access somehow $target_folder_and_file_name from the PHP code in main.js.php ?

  • How do I implement configurations and settings?

    - by Malvolio
    I'm writing a system that is deployed in several places and each site needs its own configurations and settings. A "configuration" is a named value that is necessary to a particular site (e.g., the database URL, S3 bucket name); every configuration is necessary, there is not usually a default, and it's typically string-valued. A setting is a named value but it just tweaks the behavior of the system; it's often numeric or Boolean, and there's usually some default. So far, I've been using property files or thing like them, but it's a terrible solution. Several times, a developer has added a requirement for a configuration but not added the value to file for the live configuration, so the new release passed all the tests, then failed when released to live. Better, of course, for every file to be compiled — so if there's a missing configuration, or one of the wrong type, it won't get past the compiler — and inject the site-specific class into the build for each site. As a bones, a Scala file can easy model more complex values, especially lists, but also maps and tuples. The downside is, the files are sometimes maintained by people who aren't developers, so it has to be pretty self-explanatory, which was the advantage of property files. (Someone explain XML configurations to me: all the complexity of a compilable file but the run-time risk of a property file.) What I'm looking for is an easy pattern for defining a group required names and allowable values. Any suggestions?
