  • How to correctly cache images

    - by James Simpson
    I just installed Google's Page Speed plugin to Firebug, and everything looks good except for caching. I have set headers to cache my JS and CSS files, but it says the images aren't being cached. How can I make sure the images get cached for 30 days? These are static images, so I can't just add the headers with PHP like I did with the other files.

  • How to optimize this user ranking query

    - by James Simpson
    I have 2 databases (users, userRankings) for a system that needs to have rankings updated every 10 minutes. I use the following code to update these rankings which works fairly well, but there is still a full table scan involved which slows things down with a few hundred thousand users. mysql_query("TRUNCATE TABLE userRankings"); mysql_query("INSERT INTO userRankings (userid) SELECT id FROM users ORDER BY score DESC"); mysql_query("UPDATE users a, userRankings b SET a.rank = b.rank WHERE a.id = b.userid"); In the userRankings table, rank is the primary key and userid is an index. Both tables are MyISAM (I've wondered if it might be beneficial to make userRankings InnoDB).

  • Retrieving data from MySQL in one SQL statement

    - by james.ingham
    Hi all, If I'm getting my data from Mysql like so: $result = $dbConnector->Query("SELECT * FROM branches, businesses WHERE branches.BusinessId = businesses.Id ORDER BY businesses.Name"); $resultNum = $dbConnector->GetNumRows($result); if($resultNum > 0) { for($i=0; $i < $resultNum; $i++) { $row = $dbConnector->FetchArray($result); // $row['businesses.Name']; // $row['branches.Name']; echo $row['Name']; } } Does anyone know how to print the field Name in businesses and how to print the name from branches? My only other alternative is to rename the fields or to call Mysql with two seperate queries. Thanks in advance

  • What are the arguments against the inclusion of server side scripting in JavaScript code blocks?

    - by James Wiseman
    I've been arguing for some time against embedding server-side tags in JavaScript code, but was put on the spot today by a developer who seemed unconvinced The code in question was a legacy ASP application, although this is largely unimportant as it could equally apply to ASP.NET or PHP (for example). The example in question revolved around the use of a constant that they had defined in ServerSide code. 'VB Const MY_CONST: MY_CONST = 1 If sMyVbVar = MY_CONST Then 'Do Something End If //JavaScript if (sMyJsVar === "<%= MY_CONST%>"){ //DoSomething } My standard arguments against this are: Script injection: The server-side tag could include code that can break the JavaScript code Unit testing. Harder to isolate units of code for testing Code Separation : We should keep web page technologies apart as much as possible. The reason for doing this was so that the developer did not have to define the constant in two places. They reasoned that as it was a value that they controlled, that it wasn't subject to script injection. This reduced my justification for (1) to "We're trying to keep the standards simple, and defining exception cases would confuse people" The unit testing and code separation arguments did not hold water either, as the page itself was a horrible amalgam of HTML, JavaScript, ASP.NET, CSS, XML....you name it, it was there. No code that was every going to be included in this page could possibly be unit tested. So I found myself feeling like a bit of a pedant insisting that the code was changed, given the circumstances. Are there any further arguments that might support my reasoning, or am I, in fact being a bit pedantic in this insistence?

  • Why is autorelease especially dangerous/expensive for iPhone applications?

    - by e.James
    I'm looking for a primary source (or a really good explanation) to back up the claim that the use of autorelease is dangerous or overly expensive when writing software for the iPhone. Several developers make this claim, and I have even heard that Apple does not recommend it, but I have not been able to turn up any concrete sources to back it up. SO references: autorelease-iphone Why does this create a memory leak (iPhone)? Note: I can see, from a conceptual point of view, that autorelease is slightly more expensive than a simple call to release, but I don't think that small penalty is enough to make Apple recommend against it. What's the real story?

  • how to deploy jboss app over the internet

    - by james mccvoy
    I am using JBOSS 7 AS. I am deploying the projects via the linux box by the cmd like so bin/standalone.sh -b [ipaddress] This works fine only when i am on the network, however it doesn't work when i'm outside the network or over the internet. How do i launch it so people can access it over the internet? I tried this but it doesnt work. bin/standalone.sh -b 0.0.0.0 It says: Google Chrome could not load the webpage because took too long to respond. The website may be down, or you may be experiencing issues with your Internet connection.

  • Regular expressions and matching URLs with metacharacters

    - by James P.
    I'm having trouble finding a regular expression that matches the following String. Korben;http://feeds.feedburner.com/KorbensBlog-UpgradeYourMind?format=xml;1 One problem is escaping the question mark. Java's pattern matcher doesn't seem to accept \? as a valid escape sequence but it also fails to work with the tester at myregexp.com. Here's what I have so far: ([a-zA-Z0-9])+;http://([a-zA-Z0-9./-]+);[0-9]+ Any suggestions? Edit: The original intent was to match all URLs that could be found after the first semi colon.

  • Optimal Sharing of heavy computation job using Snow and/or multicore

    - by James
    Hi, I have the following problem. First my environment, I have two 24-CPU servers to work with and one big job (resampling a large dataset) to share among them. I've setup multicore and (a socket) Snow cluster on each. As a high-level interface I'm using foreach. What is the optimal sharing of the job? Should I setup a Snow cluster using CPUs from both machines and split the job that way (i.e. use doSNOW for the foreach loop). Or should I use the two servers separately and use multicore on each server (i.e. split the job in two chunks, run them on each server and then stich it back together). Basically what is an easy way to: 1. Keep communication between servers down (since this is probably the slowest bit). 2. Ensure that the random numbers generated in the servers are not highly correlated.

  • How do I send signed emails from ActionMailer?

    - by James A. Rosen
    I'm using GMail as my SMTP server. I have that configuration working just fine: # config/initializers/action_mailer.rb: ActionMailer::Base.smtp_settings = { :tls => true, :address => "smtp.gmail.com", :port => "587", :domain => "www.example.org", :authentication => :login, :user_name => "[email protected]", :password => "it's a secret" } I also have a public/private RSA key pair in config/ssl/rsa.public and config/ssl/rsa.private. What do I do to sign the emails before shipping them off to GMail's SMTP server?

  • Why does TrimStart trims a char more when asked to trim "PRN.NUL" ?

    - by James
    Here is the code: namespace TrimTest { class Program { static void Main(string[] args) { string ToTrim = "PRN.NUL"; Console.WriteLine(ToTrim); string Trimmed = ToTrim.TrimStart("PRN.".ToCharArray()); Console.WriteLine(Trimmed); ToTrim = "PRN.AUX"; Console.WriteLine(ToTrim); Trimmed = ToTrim.TrimStart("PRN.".ToCharArray()); Console.WriteLine(Trimmed); ToTrim = "AUX.NUL"; Console.WriteLine(ToTrim); Trimmed = ToTrim.TrimStart("AUX.".ToCharArray()); Console.WriteLine(Trimmed); } } } The output is like this: PRN.NUL UL PRN.AUX AUX AUX.NUL NUL As you can see, the TrimStart took out the N from NUL. But it doesn't do that for other strings even if it started with PRN. I tried with .NET Framework 3.5 and 4.0 and the results are same. Are there any explanation on what causes this behavior?

  • IgnoreArguments including an Action<T>

    - by James L
    I'm probably missing something obvious here, so apologies in advance! Using Rhino Mocks, how do I set an expectation that a method taking an Action will be called, but I want to use IgnoreArguments. Obviously I can't specify null as that isn't an Action, and I dont want any meaningless code in the test. As I said, it's probably obvious by the syntax is eluding me at the moment!

  • How to strip a GET property from the URL using PHP

    - by James
    I have the following function that get's the current page URL: <?php // get current page url function currentPageUrl() { $pageURL = 'http'; if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";} $pageURL .= "://"; if ($_SERVER["SERVER_PORT"] != "80") { $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; } else { $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; } echo $pageURL; } ?> Which prints: http://localhost/gallery.php?id=23&type=main I want to remove "&type=main" which is present in the url. So before echoing $pageURL I add the following line: $pageUrl = preg_replace("&type=main", "", $pageURL); But it still returns the full url including type=main. How can I get rid of that from the url?

  • Cocoa framework development: sharing between projects

    - by e.James
    I am currently developing a handful of similar Cocoa desktop apps. In an effort to share code between them, I have identified a set of core classes and functions that can be common across all of these applications. I would like to bundle this common code into a framework which all of my current applications (and any future ones) can link against. Now, here's the hard part: I'm going to be developing this framework as I go, so I need each of my desktop apps to have a reference to it, but I want to be able to edit the framework source code from within each of the app projects and have the framework automatically rebuilt as required. For example, let's say I have the Xcode project for DesktopAppNumberOne open, and I decide that one of my framework classes needs to be changed. I would like to: Open and edit the source file for that framework class without having to open the framework project in Xcode. Hit "build" on DesktopAppNumberOne, and see the framework rebuilt first (because one of its sources has changed), then see parts of DesktopAppNumberOne rebuilt (because one of the frameworks it links against has changed). I can see how to do this with only one app and one framework, but I'm having trouble figuring out how to do it with multiple apps that share a single framework. Has anyone had success with this approach? Am I perhaps going about this the wrong way? Any help would be appreciated.

  • When to use MVC Scaffolding via NuGet vs MVC Scaffolding via MVC3 Tools Update

    - by James
    I am a little confused about the various different "mainstream" scaffolding options for MVC3. There is a NuGet package called MVCScaffolding. It first showed up in Jan 2011, but seems to be active and have recent updates, and be developed by Scott Hanselman, among others. Then in May 2011 came the MVC3 Tools Update. This seems like it incorporated the original scaffolding ideas into an "out of the box" scaffolding options. However, this has not been updated since. So - what is the relationship between these two scaffoldings (if any). Are there cases when one should be used over the other, or is it just a matter of taste? Does Visual Studio 2012 or MVC4 change the game on any of this? Thanks for any input.

  • Adding events to ScatterViewItems when implicitly creating them

    - by James Hay
    Not sure there's too many surface developers on here but hey ho... If i have a scatterview which implicity creates the ScatterViewItem objects (see below), is it possible to retireve the contact events for each scatterViewItem? Also when i wrap tyhe image object in a ScatterViewItem explicitly the item no longer works. Could anyone advise as to why this is the case? <s:ScatterView ItemsSource="{StaticResource DummyData}" > <s:ScatterView.ItemTemplate> <DataTemplate> <Image Source="{Binding Path=ImagePath}" /> </DataTemplate> </s:ScatterView.ItemTemplate> </s:ScatterView>

  • Read a specific range of lines from a file using c

    - by James Joy
    I have the following content in a file: hhasfghgsafjgfhgfhjf gashghfdgdfhgfhjasgfgfhsgfjdg jfshafghgfgfhfsghfgffsjgfj . . . . . startread hajshjsfhajfhjkashfjf hasjgfhgHGASFHGSHF hsafghfsaghgf . . . . . stopread . . . . . . jsfjhfhjgfsjhfgjhsajhdsa jhasjhsdabjhsagshaasgjasdhjk jkdsdsahghjdashjsfahjfsd I need to read the lines from the next line of startread till the previous line of stopread using a c code and store it to a string variable(of course with a \n for every line breaks). How can i achieve this? I have used fgets(line,sizeof(line),file); but it starts reading from the beginning. I don't have the exact line number to start and stop reading since the file is written by another C code. But there are these identifiers startread and stopread to identify whereto start reading. Operating platform is linux. Thanks in advance.

  • How to have multiple instances of jQuery plugin on single page?

    - by James Skidmore
    I'm writing a simple jQuery plugin, but I'm having trouble being able to use multiple instances on a page. For instance, here is a sample plugin to illustrate my point: (function($) { $.fn.samplePlugin = function(options) { if (typeof foo != 'undefined') { alert('Already defined!'); } else { var foo = 'bar'; } }; })(jQuery); And then if I do this: $(document).ready(function(){ $('#myDiv').samplePlugin({}); // does nothing $('#myDiv2').samplePlugion({}); // alerts "Already defined!" }); This is obviously an over-simplified example to get across the point. So my question is, how do I have two separate instances of the plugin? I'd like to be able to use it across multiple instances on the same page. I'm guessing that part of the problem might be with defining the variables in a global scope. How can I define them unique to that instance of the plugin then? Thank you for your guidance!

  • How Do I Add Value To All Previous Values In Array

    - by James
    Lets say I have the following array: my_array = [1, 5, 8, 11, -6] I need to iterate over this array and add the values prior to the current value together. An example will probably be easier to understand. I need to return an array that should look something like this: final_array = [1, 6, 14, 25, 19] I have tried doing something like this: my_array.collect {|value| value + previous_values } But obviously that doesn't work because I can't figure out how to get the previous values in the array. I am a programming noob so this might be easier than I am making it. I am pretty sure I need to use either collect or inject, but I can't seem to figure out how to do this. Any help would be appreciated.
