  • How do I read the cache of Chrome and Firefox programmatically on the Mac?

    - by John Gallagher
    Background I want to access the cache of Chrome and Firefox in my Cocoa application. I need to get the HTML for pages accessed recently. Safari is a piece of cake - all this information is available in SQLite data stores, but not so in Chrome and Firefox. The Problem For Firefox, the cache is in /Library/Caches/Firefox/Profiles/xxx.default/Cache with filenames _CACHE_001_ _CACHE_002_ _CACHE_003_ and _CACHE_MAP_ For Chrome, the cache is in /Library/Caches/Google/Chrome/Default/Cache with filenames data_0 data_1 data_2 and data_3 What I've tried The only article I can find that sheds any light on what format these caches are in is here. It recommends a Cache Viewer tool, but doesn't explain how one might do this programmatically. Questions Is there any way of reconstructing this data using command line tools or the Cocoa framework? Or is it much too low level? Is there another way of getting at the HTML of recent web pages that I don't know about?

  • How to deal with databases for websites written in Java, more specifically Wicket?

    - by John
    Hi there. I'm new to website development using Java but I've got started with Wicket and make a little website. I'd like to expand on what I've already made (a website with a form, labels and links) and implement database connectivity. I've looked at a couple of examples, in example Mystic Paste, and I see that they're using Hibernate and Spring. I've never touched Hibernate or Spring before and to be honest the heavy use of annotations scare me a little bit as I haven't really made use of them before, with the exception of supressing warnings and overriding. At this point I have one Connection object which I set up in the WebApplication class upon initialization. I then retrieve this connection object whenever I need to perform queries. I don't know if this is a bad approach or not for a production web application. All help is greatly appreciated.

  • Java String Replace and null characters

    - by praspa
    Testing out someone elses code (of course it was ...) , I noticed a few JSP pages printing funky non-ascii characters. Taking a dip into the source I found this tidbit. // remove any periods from first name e.g. Mr. John --> Mr John firstName = firstName.trim().replace('.','\0'); Does replacing a character in a String with a null character even work in Java? I know that '\0' will terminate a c-string. Would this be the culprit to the funky characters? Thanks PR

  • Workaround for richfaces combobox hotkey bug

    - by John
    Hi, Does anyone know a workaround for the bug https://jira.jboss.org/jira/browse/RF-8076 ? Just to clarify things, we have a form with multiple inputs, one of them being a combobox with auto complete features. We've setup a hotkey via <rich:hotKey key="return" ... /> It works great everywhere except in the combobox, and I would really like to get it working on the combobox as well. The behaviour I want when the ENTER key is pressed inside the combobox is: If the combobox context was modified by auto complete then do nothing Else action the event on ENTER key pressed We're running on seam/richfaces. I'm open to any workaround, but simplicity is much sought for. Thanks!

  • Seeking References To MSVC 9.0's C++ Standards Compliance

    - by John Dibling
    I "know" (hopefully) that MSVC 9.0 Implements C++ 2003 (ISO/IEC 14882:2003). I am looking for a reference to this fact, and I am also looking for any research that has been done in to how compliant MSVC 9.0 is with that version of the Standard. I have searched for and not been able to find a specific reference from MicroSoft that actually says something to the effect that MSVC implements C++ 2003. Some of the out-of-date documentation says things like "this release achieves roughly 98% compliance" (when referring to MSVC .NET 2003's conformance to C++ 1997). But I want a link to a document from MS that says "MSVC 9.0 implements blah," and another link to an independent group that has tested the conformance of MSVC 9.0. Do you know of any such links?

  • PHP - Plesk - Cron - Allowed memory size exhausted?

    - by John
    ini_set('max_execution_time',0); ini_set('memory_limit','1000M'); These are the first two lines at the very top of my script. I was under the impression if I ran something via cron memory limits didn't apply, but I was wrong. Safe mode is off and when I test to see if these values are being set they are but I keep getting the good ol' "PHP Fatal: Memory exhausted" error. Any ideas what I may be doing wrong? And whats the "more elegant way" of writing "infinite" for the "memory limit" value is it -1 or something?

  • How to tell what account my webservice is running under in Visual Studio 2005

    - by John Galt
    I'm going a little nuts trying to understand the doc on impersonation and delegation and the question has come up what account my webservice is running under. I am logged as myDomainName\johna on my development workstation called JOHNXP. From Vstudio2005 I start my webservice via Debug and the wsdl page comes up in my browser. From Task Manager, I see the following while sitting at a breakpoint in my .asmx code: aspnet_wp.exe pid=1316 UserName=ASPNET devenv.exe pid=3304 UserName=johna The IIS Directory Security tab for the Virtual Directory that hosts my ws.asmx code has "Enable Anonymous access" UNCHECKED and has "Integrated Windows Authentication" CHECKED. So when the MSDN people state "you must configure the user account under which the server process runs", what would they be refering to in the case of my little webservice described above? I am quoting from: http://msdn.microsoft.com/en-us/library/aa302400.aspx Ultimately, I want this webservice of mine to impersonate whatever authenticated domain user browses through to an invoke of my webservice. My webservice in turn consumes another ASMX webservice on a different server (but same domain). I need this remote webservice to use the impersonated domain user credentials (not those of my webservice on JOHNXP). So its getting a little snarly for me to understand this and I see I am unclear about the account my web service uses. I think it is ASPNET in IIS 5.1 on WinXP but not sure.

  • R: How can I reorder the rows of a matrix, data.frame or vector according to another one.

    - by John
    test1 <- as.matrix(c(1, 2, 3, 4, 5)) row.names(test1) <- c("a", "b", "c", "d", "e") test2 <- as.matrix(c(6, 7, 8, 9, 10)) row.names(test2) <- c("e", "d", "c", "b", "a") test1 [,1] a 1 d 2 c 3 b 4 e 5 test2 [,1] e 6 d 7 c 8 b 9 a 10 How can I reorder test2 so that the rows are in the same order as test1? e.g: test2 [,1] a 10 d 7 c 8 b 9 e 6 I tried to use the reorder function with: reorder (test1, test2) but I could not figure out the correct syntax. I see that reorder takes a vector, and I'm here using a matrix. My real data has one character vector and another as a data.frame. I figured that the data structure would not matter too much for this example above, I just need help with the syntax and can adapt it to my real problem.

  • SWI-Prolog Semantic Web Library and Python Interface

    - by John Peter Thompson Garcés
    I want to write a Python web application that queries RDF triples using Prolog. I found pyswip for interfacing Python with SWI-Prolog, and I am currently looking into SWI-Prolog's RDF capabilities. I am wondering if anyone has tried this before--and if anyone has: what did your setup look like? How do you get pyswip to work with the SWI-Prolog semantic web library? Or is there another Python-Prolog interface that makes this easier?

  • Fluently setting C# properties and chaining methods

    - by John Feminella
    I'm using .NET 3.5. We have some complex third-party classes which are automatically generated and out of my control, but which we must work with for testing purposes. I see my team doing a lot of deeply-nested property getting/setting in our test code, and it's getting pretty cumbersome. To remedy the problem, I'd like to make a fluent interface for setting properties on the various objects in the hierarchical tree. There are a large number of properties and classes in this third-party library, and it would be too tedious to map everything manually. My initial thought was to just use object initializers. Red, Blue, and Green are properties, and Mix() is a method that sets a fourth property Color to the closest RGB-safe color with that mixed color. Paints must be homogenized with Stir() before they can be used. Bucket b = new Bucket() { Paint = new Paint() { Red = 0.4; Blue = 0.2; Green = 0.1; } }; That works to initialize the Paint, but I need to chain Mix() and other methods to it. Next attempt: Create<Bucket>(Create<Paint>() .SetRed(0.4) .SetBlue(0.2) .SetGreen(0.1) .Mix().Stir() ) But that doesn't scale well, because I'd have to define a method for each property I want to set, and there are hundreds of different properties in all the classes. Also, C# doesn't have a way to dynamically define methods prior to C# 4, so I don't think I can hook into things to do this automatically in some way. Third attempt: Create<Bucket>(Create<Paint>().Set(p => { p.Red = 0.4; p.Blue = 0.2; p.Green = 0.1; }).Mix().Stir() ) That doesn't look too bad, and seems like it'd be feasible. Is this an advisable approach? Is it possible to write a Set method that works this way? Or should I be pursuing an alternate strategy?

  • Career Choice in JEE, are EJBs standard?

    - by John Baker
    I have chosen to go the JEE route for a career path but I have been having a hard time determining which core technologies that I need to be most familiar with. I'm at the point I can write web apps without a problem with JSP's and regular servlets using JDBC or some basic Hibernate stuff (I know, HTML, CSS and have used MVC extensively on a number of different platforms). What I'm trying to find out is if there is some standard as far as J2EE technologies go. When I look at most of the Job listings, occasionally you will see someone mention Struts or Spring but rarely do I see any mention of EJB's. So my question is really, are EJB's basically required by most JEE employers? Or are most of them working with POJO's? Is it a mix? I have a hard time figuring out if I should put the majority of my time into Struts, Spring/Hibernate, EJB's, etc. And if I do need to master EJB's what version should I learn? 2.1 or 3.0. 3.0 has some obviously better features but I figure a lot of companies probably chose to write their apps in 2.1 just because it was the standard of the time and now migrating would be a big deal. Any advice on this is greatly appreciated.

  • How can I extend a LinkButton to allow HTML text in Flex?

    - by John Isaacks
    I am feeding the label to my LinkButton directly from a string I receive from a Google API that puts html to format the label. I want to extend linkbutton to allow this. I wrote a class myself to allow html text for the label and that aspect of it works but now the background that appears when you hover is way too big. I tried to override measure() to fix this but I didn't have a clue how. Here is the class I wrote: package com.kranichs.components { import mx.controls.LinkButton; public class HTMLLinkButton extends LinkButton { protected var _isHTML:Boolean; public function HTMLLinkButton() { super(); } [Bindable] public function set isHTML(value:Boolean):void { _isHTML = value; } public function get isHTML():Boolean { return _isHTML; } override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void { super.updateDisplayList(unscaledWidth, unscaledHeight); if(_isHTML) { textField.htmlText = label; } } } }

  • ASP.NET WebMethod Returns JSON wrapped in quotes

    - by CL4NCY
    Hi, I have an asp.net page with a WebMethod on it to pass JSON back to my javascript. Bellow is the web method: [WebMethod] public static string getData(Dictionary<string, string> d) { string response = "{ \"firstname\": \"John\", \"lastname\": \"Smith\" }"; return response; } When this is returned to the client it is formatted as follows: { \"d\": \"{ \"firstname\": \"John\", \"lastname\": \"Smith\" }\" } The problem is the double quotes wrapping everything under 'd'. Is there something I've missed in the web method or some other means of returning the data without the quotes? I don't really want to be stripping it out on the client everytime. Also I've seen other articles where this doesn't happen. Any help would be appreciated thanks.

  • selecting a row by means of a button ... using didSelectRowAtIndexPath

    - by John Smith
    hey people , I have a question concerning a button I would like to create which selects my previous selected row. This is what I came up so far but since I'm new with the functionality and such I could definately use some pointers I created a toolbar with a button and behind this button is the following action. -(void)clickRow { selectedRow = [self.tableView indexPathForSelectedRow]; [self.tableView:[self tableView] didSelectRowAtIndexPath:selectedRow]; } in my didSelectRowAtIndexPath there is a rootViewController being pushed rvController = [RootViewController alloc] ...etc So what I would like is my function clickRow to select the row and push the new rootviewcontroller (which has the right info since I'm using a tree ). I tried something like this as well -(void)clickRow { NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; NSArray *Children = [dictionary objectForKey:@"Children"]; rvController = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:[NSBundle mainBundle]]; rvController.CurrentLevel += 1; rvController.CurrentTitle = [dictionary objectForKey:@"Title"]; [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController release]; } The last function works a little but a little is not enough;) For instance if I press the middle row or any other it constantly selects the toprow. thnx all for those of you reading and trying to help

  • Packaging an application that uses the ImageMagick C API

    - by John Gardeniers
    I've created a little Windows app that uses the ImageMagick C API but have run into a bit of a brick wall. The app works fine and I'm ready to share it with a few others in our organisation but I can't find documentation on distributing such an app without installing ImageMagick on the target machine. Does anyone here have information, or a link to information, that details how to package this up for distribution? What DLLs are required and which one(s) need to registered with Windows? The target users will be on a mix of XP and Win7.
