Is it possible to declare an applet's classpath into the JAR and not into the applet tag ?

- by Laurent K

I'm building an applet with a quite big classpath. (externalLib1.jar, externalLib2.jar, etc.) MyApplet.jar, the applet's jar contains a Manifest.MF including a ClassPath attribute listing all the required jars. ClassPath = externalLib1.jar externalLib2.jar externalLib3.jar externalLib4.jar etc.jar Is there a way to load the applet without listing all the jars in the <applet> tag ? I would like to have : <applet code="MyApplet.class" codebase="mycodeBase" archive="MyApplet.jar"/> and not : <applet code="MyApplet.class" codebase="mycodeBase" archive="MyApplet.jar,externalLib1.jar,externalLib2.jar,externalLib3.jar,externalLib4.jar,etc.jar"/> Is there a way to achieve this ? Did I miss something, somewhere ? Thank you for your help !

Emacs: Define a function which loads the file where the function itself is defined

- by damd

I'm refactoring a bit in my Emacs set up and have come to the conclusion that I want to use a different init file than the default one. So basically, in my ~/.emacs file, I have this: (load "/some/directory/init.el") Up until now, that's been working just fine. However, now I want to redefine an old command that I've used for ages, which opens my init file: (defun conf () "Open a buffer with the user init file." (interactive) (find-file user-init-file)) As you can see, this will open ~/.emacs no matter what I do. I want it to open /some/directory/init.el, or wherever the conf command itself is defined. How would I do that?

How to read from CSS files with jQuery

- by Neurofluxation

Ok, I have a HTML page with jQuery included. I have a CSS file with a good load of lines in, I would like to read all styles for a given element from the external CSS file... Not the inline styles... I have the following code (which looks like it should work...): var styleProperties= {}; var getCssProperties = ['width', 'margin', 'height']; for (c=0;i<=returnStyleProps.length;c++) { styleProperties[returnStyleProps[c]] = $('div#container').css(returnStyleProps[c]); alert(styleProperties); } alert(styleProperties); But this only seems to alert: "[Object Object]" Any ideas you clever people?

Objective-c class initializer executes multiple times

- by apisip

Unless I misunderstood it, this LINK from Apple's documentation clearly states that the class initializer, "+ (void)initialize)", only executes once per class. Here is the excerpt: Special Considerations initialize it is invoked only once per class. If you want to perform independent initialization for the class and for categories of the class, you should implement load methods. However, I'm getting a weird behavior on my project and the initializer is being executed twice. So I have to check if _classContext is null. I only got one class that has this method. What are the possible reasons why this is happening? I'm using XCode 4.5.2 and OS X 10.8.2. I got multiple iOS simulators, iPhone 5.1 and 6.0. + (void) initialize { num++; NSLog([NSString stringWithFormat:@"Times: %i", num]); if(_classContext == nil) _classContext = [[myClass alloc] init]; }

Stop Rails from unloading a module in development mode

- by Gareth

I have a module in my Rails app that lives in /lib module MyModule mattr_accessor :the_variable class << self def setup yield this end end end From my environments/#{RAILS_ENV}.rb file I can then set an environment-specific value for the_variable: MyModule.setup do |my_module_config| my_module_config.the_variable = 42 end This is lovely, and it seems to work (almost) fine. The problem is that in development mode, Rails via ActiveSupport::Dependencies unloads a load of modules, and reloads them in time for the new request. This is usually a great behaviour because it means you don't need to restart your localhost server when you make a code change. However, this also clears out my initialised the_variable variable, and when the next request comes in the initialiser (obviously) isn't run again. The net effect is that subsequent requests end up having MyModule.the_variable set to nil rather than the 42 that I'm looking for. I'm trying to work out how to stop Rails unloading my module at the end of the request, or alternatively find another way to cleanly provide environment specific configuration for my modules. Any ideas? :-/

Random List of millions of elements in Python Efficiently

- by eWizardII

Hello, I have read this answer potentially as the best way to randomize a list of strings in Python. I'm just wondering then if that's the most efficient way to do it because I have a list of about 30 million elements via the following code: import json from sets import Set from random import shuffle a = [] for i in range(0,193): json_data = open("C:/Twitter/user/user_" + str(i) + ".json") data = json.load(json_data) for j in range(0,len(data)): a.append(data[j]['su']) new = list(Set(a)) print "Cleaned length is: " + str(len(new)) ## Take Cleaned List and Randomize it for Analysis shuffle(new) If there is a more efficient way to do it, I'd greatly appreciate any advice on how to do it. Thanks,

How can a Delphi TPersistent object calculate its own deserialization time?

- by mjustin

For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": start of the deserialization process after the deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event So the log for TMyForm.Create(nil) could look like: - 00.000 instance created - 00.010 before deserialization - 01.823 after deserialization - 02.340 before OnFormCreate Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions.

What's the proper way to use sqlite on the iPhone?

- by Elliot Chen

Hi, Experts: Can you please give some suggestions on sqlite using on the iPhone? Within my application, I use a sqlite DB to store all local data. Two methods can be used to retrieve those data during running time. 1, Load all the data into memory at initialization stage. (More memory used, less DB open/close operation needed) 2, Read corresponding records when necessary, free the occupied memory after using. (Good habit for memory using, but much DB open/close operations needs). I prefer to use method 2, but not sure whether too many DB opening/closing operations could affect app's efficiency. Or do you think I can 'upgrade' method 2 by opening DB when app launches and closing DB when app quits? Thanks for your suggestions very much!

What can I use the Google App Engine for?

- by Sergio Boombastic

This question possibly doesn't belong here. We'll see how the answers pan out, if this doesn't belong here please move it to where it belongs. I'm following the getting started guide for Google App Engine, and I'm seeing what it can and can't do. Basically, I'm seeing it's very similar to an MVC pattern. You create your model, then create a View that uses that Model to display information. Not only that, but it uses a controller of some kind in this fashion: application = webapp.WSGIApplication( [('/', MainPage)], debug=True) My question is, why would you use this Google App Engine if it's the same as using a number of other MVC frameworks? Is the only benefit you gain the load balancing being handled by Google automagically? What is a good example of something you would need the App Engine for? I'm trying to learn, so thanks for the discussion.

Actionscript 2.0 Functions problem

- by Joshua

I have two problems. The first problem is with the following functions; when I call the function in (enterFrame), it doesn't work: onClipEvent (load) { function failwhale(levelNum) { _root.gotoAndStop("fail"); failFrom = levelNum; } function guardSightCollision(guardName, guardSightName) { if (_root.guardName.guardSightName.hitTest(_x, _y+radius, true)) { failwhale(1); } if (_root.guardName.guardSightName.hitTest(_x, _y-radius, true)) { failwhale(1); } if (_root.guardName.guardSightName.hitTest(_x-radius, _y, true)) { failwhale(1); } if (_root.guardName.guardSightName.hitTest(_x+radius, _y, true)) { failwhale(1); } } } onClipEvent (enterFrame) { guardSightCollision(guard1, guard1Sight); } Why doesn't it work?... The second problem lies in the failFrom variable: function failwhale(levelNum) { _root.gotoAndStop("fail"); failFrom = levelNum; } How do I make failFrom a "global" variable in that it can be accessed anywhere (from actionscript in frames and even movieclips)...Right now, when I try to trace failFrom in a different frame, it is "undefined".

UDF function with library dependencies on MySQL 5.1

- by Fredrik

I'm having a problem with a MySQL UDF function (mychem.sourceforge.net) that's dependent on a large library (openbabel.org) which is in turn plugin based. The problem is that the format plugins to openbabel doesn't seem to load in MySQL 5.1 and I suspect it might be due to the plugin_dir setting. I have set plugin_dir to /usr/lib/ which is the location for both libmychem.so and libopenbabel.so as well as the directory openbabel that contains the format plugins. Is there a way to turn off the plugin_dir restriction in MySQL (preferably without compiling MySQL from sources) so that I can test this hypothesis or do you have a different idea on what might cause the problem? All this is done on Ubuntu 10.04 (but I had the same kind of problems on 8.04, where I managed to get it working after a lot of steps that I unfortunately have forgotten...) I have turned off apparmor during testing and it doesn't help either.

Trying to make my leaflet map work on internet explorer

I have been tearing my hair out of late trying to get my web map working on internet explorer. It's working flawlessly on every other major browser but none of the content will load in IE. Anyone out there who's good at browser testing that could help out? I know the leaflet javascript api, which I'm using for this project, supports IE in theory. In practice this isn't working out too well... Link to a live version of the web map: https://mywebspace.wisc.edu/axler/SLRE_Deep_Map/index2.html Let me know if there is anything else I could add that would help in deciphering this problem...

access models and forms within modules

- by sims

Hi Stackers, What is the best way to access my models and forms from a controller of a module? Let's explain with "pictures": /application/module/storage/controllers/IndexController.php needs to call readAction in the class called storage_Model_Files in /application/module/storage/models/Files.php I've made this app's dir structure and these forms and models with zf.sh (Zend_Tool). I've read about all sorts of ways of manually including these files. I want to lazy load them much like everything is done automatically with the default module. I can't seem to find how in the docs. Does that make sense? I have: resources.frontController.moduleDirectory = APPLICATION_PATH "/modules" in my application.ini file. So I can access my controllers fine. Thanks for your help!

Most common software development mistakes

- by hgulyan

Inspired by Dealing with personal failure, I remembered my own failed software development experience. Finally I agreed to rewrite existing application. It took me less than a week to rewrite existing app and more up to 2 months to write from zero my own. That 2 months were really hard and interesting. It was my first big software development process. I researched almost everything concerning to my application. Read Code Complete. Even some articles on how to create user interface. Some psychology stuff. Typography, Colors. DAL, DB Structure, SOA, Patterns, UML, Load testing etc. I hope, that after a month or 2 I would get opportunity to continue working on my failed project, but before that, I would like to ask: What are common mistakes in software development? What you shouldn't do in any case?

Managing the localization of Java properties files

- by andri

I have a Web application written in Java that is targeting several countries, all of which speak different languages (and more often than not, several languages -- that's Europe for you). We have a bunch of .properties files that hold the localized strings, and our current procedure is to e-mail the language-specific files to our partners for updating before doing major updates. However, this process is rather error-prone, as sometimes people forget to translate new strings and sometimes new strings don't get added to every language file, thus small mistakes get through very easily. Does anyone know of any existing software that could help us clear this mess? At a bare minimum, I'm thinking of something that would allow you to load a master file (for example, in English), a localized file and then would highlight the keys that were added to or removed from the master file.

Why is display:inline killing IE 8.0 performance?

- by monstermensch

I have an image gallery based on this jQuery plugin: http://jqueryfordesigners.com/demo/slider-gallery.html This works really well in Firefox, Chrome and even IE 7.0, but when I try it with more than 50 images in IE 8.0 the performance is incredible slow. Just hovering over the thumbnail brings the CPU load to 100%. At first I thought it's a Javascript problem, so I used the IE profiler, but the results were normal. Next I checked the CSS and finally found the cause: .sliderGallery UL LI { display: inline; } This gets the thumbnails to align horizontally. If I chance it to display:block, performance is fine and the scroller is still working but obviously it looks funny, because the thumbs are aligned vertically. My questions: Why does IE 8 have this problem with many display:inline elements What can I do to solve it I'll gladly provide more information if necessary.

why does $.ajax(..) not work for me?

- by dr jerry

I'm running jquery from a file. And I'm trying to load a svg file from my localhost to populate a svg canvas. However that does not work as expected. What I do from filesystem: $.ajax({ url: url , timeout: 1000, complete: function(xml) { alert('complete'); }, success: function(xml, status, xreq) { alert('success'); }, error: function() { alert('error'); } }); the url reads: http://localhost/image.svg, when I read this url directly from an addressbar from the browser, the pages remains white but the pagesource displays the source of image.svg. Debugging the $.ajax code above, reveals that the success: method is hit, but xml response remains empty. Any help is greatly appreciated. regards, jeroen.

Why browser doesnt recognize jquery when <script src="...jquery.js> is on a html page served by Goo

- by indiehacker

jquery.js source code is not being recognised by browser using my page.html served by Google App Engine as a http:some_request to the SDK, BUT when I load the exact same page.html into the browser directly from my local hard drive as jquery.js all works OK, it is recognized, so I know my path is OK.... I don't understand? In the header of my page.html I have the following: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js" type="text/javascript"></script> I also tried without success in the header this: <script src="/static/jquery.js" type="text/javascript"></script> I am working along with the examples in the [Jquery tutorial][1]. I am sure there is something simple I dont understand about how .html pages served to the browser from app engine interact differently with the browser than what I normally would expect....but I frustratingly just cant get it.....everything else I have with my app engine app is working fine......would love some help so i can move forward....
