It is some like history of USB and System data . i think this feature is in KDE this will really useful in may ways. it provides real time and monitoring utility to monitor USB mass storage devices activities on any machine .

• What is the most concise, unambiguous syntax for operator associated methods (for overloading etc.) that doesn't pollute the namespace?

  - by Doug Treadwell

  Python tends to add double underscores before its built-in or overloadable operator methods, like __add(), whereas C++ requires declaring overloaded operators as operator + (Thing& thing) { /* code */ } for example. Personally I like the operator syntax because it seems to be more explicit and keeps these operator overloading methods separated from other methods without introducing weird prefix notation. What are your thoughts? Also, what about the case of built-in methods that are needed for the programming language to work properly? Is name mangling (like adding __ prefix or sys or something) the best solution here? What do you think about having another type of method declaration, like ... "system method" for lack of creativity at the moment. So there would be two kinds of declarations: int method_name() { ... } system int method_name() { ... } ... and the call would need to be different to distinguish between them. obj.method_name(); vs obj:method_name(); perhaps, assuming a language where : can be unambiguously used in this situation. obj.method_name() vs obj.(system method_name)() Sure, the latter is ugly, but the idea is to make the common case simple and system stuff should be kept out of the way. Maybe the Objective-C notation of method calls? [obj method_name]? Are there more alternatives? Please make suggestions.

• Where, in an object oriented system should you, if at all, choose (C-style) structs over classes?

  - by Anto

  C and most likely many other languages provide a struct keyword for creating structures (or something in a similar fashion). These are (at least in C), from a simplified point of view like classes, but without polymorphism, inheritance, methods, and so on. Think of an object-oriented (or multi paradigm) language with C-style structs. Where would you choose them over classes? Now, I don't believe they are to be used with OOP as classes seem to replace their purposes, but I wonder if there are situations where they could be preferred over classes in otherwise object-oriented programs and in what kind of situations. Are there such situations?

• Myths: Does Deleting the Cache Actually Speed Up Your PC?

  - by The Geek

  Every time you ask somebody with a reasonable level of tech skills what you should do to speed up your PC, they start jabbering on about running ccleaner and clearing the cache. But does the act of clearing a cache really speed things up? Nope. Most people assume that all temporary files are just clutter created by lousy applications, but that isn’t actually the truth. Cache files are created by apps to store commonly used information so it doesn’t have to be generated or downloaded again.

• Composer support

  - by Tomas Mysik

  Hi all, today we would like to introduce you our Composer support which will be present in NetBeans 7.3. If anyone of you does not know Composer yet, please be informed that: "Composer is a tool for dependency management in PHP. It allows you to declare the dependent libraries your project needs and it will install them in your project for you." So, what support do we have in NetBeans? The first step, as usually, is to open the Composer IDE Options panel: Once it is configured properly, it is time to create composer.json file where we can define dependencies (libraries) of our PHP project: The generated file is opened so we can review it and add any libraries:  Now, you are ready to install, update or validate library dependencies of your PHP project: We hope that you enjoy this initial support and that we will be able to improve it in the next version of NetBeans.    That's all for today, as always, please test it and report all the issues or enhancements you find in NetBeans Bugzilla (component php, subcomponent Composer).

• Webcam Q&A page with guest "speakers" ideas?

  - by myladeybugg

  I want to host one way webcam Q&A's/AMA's and embed it on my sites webpage. I must be able to have specified hosts for these Q&A's connect quickly and easily to the webpage, and read user posted messages (questions) for interaction. I know there are some systems out there, like tinychat, but I'm unaware if there is anything exactly used for what I am looking for. Perhaps requiring a specific account/password before allowing streaming on the page, where I can email the host a password or directions to create an account to begin live streaming. Most of these people doing the question and answers on webcam will have little technical knowledge, so extra cookie points goes to ease of use! Thanks for ideas in advance! PS: I apologize if this is the incorrect section for posting this question, this is my first.

• How to properly develop and deploy features for existing asp.net applications on IIS

  - by Tomh

  My question actually consists of multiple questions. I'm frequently reading about companies who deploy a small subset of features for a select amount of customers using the live "database". Ruby on Rails and its ecosystem have deployment tools and database migrations to deploy or rollback such features in a live production or staging environment. My question, how is this done for an asp.net (mvc in particular) application? How do you test your newly released features against live data? Do you have any tools to modify the existing database and roll back changes if necessary? Do you make backups before deployment? Update Maybe I should point out that my question is not really clear, getting more answers here will help me phrase the question better. To make it easier I will describe a situation I'm commonly seeing with some of my clients. My clients have large deployments of popular web applications. They do not have staging/QA/testing servers. (yes this is not optimal). The data their apps consist of are images, xml files, user uploads and data in Sql Server. Having a few records, of their production database and a couple of dummy files is not a substitute of testing against real data in my opinion. How would you design a workflow that can create a acceptable environment to mimic a production environment before going live?

• Chrome targeted CSS

  - by Chris

  I have some CSS code that hides the cursor on a web page (it is a client facing static screen with no interaction). The code I use to do this is below: *, html { cursor: url('/web/resources/graphics/blank.cur'), pointer; } Blank.cur is a totally blank cursor file. This code works perfectly well in all browsers when I host the web files on my local server but when I upload to a Windows CE webserver (our production unit) the cursor represents itself as a black box. Odd. After some testing it seems that chrome only has a problem with totally blank cursor files when served from WinCE web server, so I created a blank cursor with one pixel as white, specifically for chrome. How do I then target this CSS rule to chrome specifically? i.e. *, html { cursor: url('/web/resources/graphics/blank.cur'), pointer; } <!--[if CHROME]> *, html { cursor: url('/web/resources/graphics/blankChrome.cur'), pointer; } <![endif]-->

• problem with phpMyAdmin advanced features

  - by typoknig

  Hi all, I am having trouble putting the final touches on my MySQL/Apache/phpMyAdmin install on a Windows XP system. I am trying to get rid of all the error message in phpMyAdmin and I have gotten rid of all of them except the ones related to "advanced features." The exact error message I have is : The additional features for working with linked tables have been deactivated. To find out why click here. I have read up on the cause of the errors but I must be missing something because I still cannot get the warning to go away. Here is what I have done: Created a linked-tables infrastructure (default name "phpmyadmin") per the phpMyAdmin instructions and enabled "pmadb" in my "config.inc.php" file. Specified (enabled) the table names in my "config.inc.php" file (there are 9 tables total). Created a "controluser" and granted only Select privilages per phpMyAdmin instructions Adjusted "controluser" pma and "controlpass" pmapass in "config.inc.php" file From what I can see these are all the instruction phpMyAdmin gives on this subject, and I am unable to locate any tutorials on the specifics of "advanced features" in phpMyAdmin. Any help would be appreciated, and be gentle, this is my first go with MySQL/phpMyAdmin

• Checkbox alignment in Internet Explorer, Firefox and Chrome

  - by Andrej

  Checkbox alignment with its label (i.e., vertical centering) cross different web browsers makes me crazy. Pasted below is standard html code: <label for="ch"><input id="ch" type="checkbox">My Checkbox</label> I tested different CSS tricks (e.g., link 1, link 2); most solutions works fine in FF, but are completely off in Chrome or IE8. I'm looking for any references or pointers to solve this issue. Thanks in advance. EDIT According to Elq suggestion I modified the HTML <div class="row"> <input type="checkbox" id="ch1" /> <label for="ch1">Test</label> </div> and CSS .row{ display: table-row; } label{ display: table-cell; vertical-align: middle; } Works now in Firefox, Internet Explorer 8, and Chrome on Windows. Fails on Firefox and Chrome on Linux. Also works in Firefox and Safari on Mac, but fails on Chrome.

• OpenLayers eraseFeatures doesn't erase features from map screen.

  - by Jenny

  I'm using OpenLayers, and have a layer for my Map, and a single Vector Layer. In this vector layer, I am using the DrawFeature control to draw a square. I have a listener waiting for a feature to be added, and then deleting any existing features (I only want one square at a time), like so: polygonLayer.events.register("beforefeatureadded", feature, function(evt){ console.log("Clearing existing polygons"); console.log(polygonLayer.features.length); polygonLayer.destroyFeatures(); polygonLayer.redraw(); });//end attempt at events registration When I check my layer.features.size, I can see that it's always 1, just like I expect, but the squares on the screen are still displayed. Even when I call .redraw() on the layer, the squares are still there. Is there some extra step I'm missing? Edit: You can find my code here: http://pastie.org/909644 Edit: Just realized: If I draw a square from previously existing coordinates, I can clear it just fine. It seems to be just the squares drawn from the controller that are an issue?

• jquery: Why do opacity animations only work with FF?

  - by incrediman

  I'm wondering why opacity animations only work with Firefox, and not with chrome or internet explorer. For example, jQuery("#a").fadeTo(1000,1); fades the element in with firefox, but just makes it appear with Chrome or IE. All I want is for the element to fade in. How can I get this to work with IE and chrome? Edit: Same thing if I use fadeIn() or any other similar function, like show()

• looking for overview of readystate and browsers

  - by Matt

  I'm finding a lot of problems with trying to determine readyState between IE8, FF3, and Chrome. so far this is what I find: Chrome, FF do not fire an event for .onReadyStateChanged Chrome, FF support .onLoad IE8 supports .onReadyStateChanged, but does not support .onLoad IE8 has also returned loaded, and complete. Mostly it states loaded, but every now and then it spits out complete. Can anyone point me to a chart or overview of browsers and the way they handle readyStates?

• Python to C# with openSSL requirement

  - by fonix232

  Hey there again! Today I ran into a problem when I was making a new theme creator for chrome. As you may know, Chrome uses a "new" file format, called CRX, to manage it's plugins and themes. It is a basic zip file, but a bit modified: "Cr24" + derkey + signature + zipFile And here comes the problem. There are only two CRX creators, written in Ruby or Python. I don't know neither language too much (had some basic experience in Python though, but mostly with PyS60), so I would like to ask you to help me convert this python app to a C# class. Also, here is the source of crxmake.py: #!/usr/bin/python # Cribbed from http://github.com/Constellation/crxmake/blob/master/lib/crxmake.rb # and http://src.chromium.org/viewvc/chrome/trunk/src/chrome/tools/extensions/chromium_extension.py?revision=14872&content-type=text/plain&pathrev=14872 # from: http://grack.com/blog/2009/11/09/packing-chrome-extensions-in-python/ import sys from array import * from subprocess import * import os import tempfile def main(argv): arg0,dir,key,output = argv # zip up the directory input = dir + ".zip" if not os.path.exists(input): os.system("cd %(dir)s; zip -r ../%(input)s . -x '.svn/*'" % locals()) else: print "'%s' already exists using it" % input # Sign the zip file with the private key in PEM format signature = Popen(["openssl", "sha1", "-sign", key, input], stdout=PIPE).stdout.read(); # Convert the PEM key to DER (and extract the public form) for inclusion in the CRX header derkey = Popen(["openssl", "rsa", "-pubout", "-inform", "PEM", "-outform", "DER", "-in", key], stdout=PIPE).stdout.read(); out=open(output, "wb"); out.write("Cr24") # Extension file magic number header = array("l"); header.append(2); # Version 2 header.append(len(derkey)); header.append(len(signature)); header.tofile(out); out.write(derkey) out.write(signature) out.write(open(input).read()) os.unlink(input) print "Done." if __name__ == '__main__': main(sys.argv) Please could you help me?

• Are there any standard one-click install/lauch mechanisms for the web?

  - by Niklas Bäckman

  The reason I ask is mostly due to how Google Chrome installation works once you click the "Accept and install" button from Firefox. After you click the installation is started directly and when it's completed Chrome itself starts up. Firefox does not show any "Save" or "Confirm" dialogs after you click the Install button (on Chrome install web page). Now, is this standard behaviour? Or might it be due to having an old version of Chrome already on the computer (Note: The new version was still installed from Firefox). Seems a bit risky to me, all you have to do is fool the user to click something and then you can do whatever you want on his machine, or? Personally I thought things like this only worked with IE/ActiveX.

• jQuery: How can I get the HTML from one div to display in another.

  - by rockinthesixstring

  I've got a small script that detects if the user is using Google Chrome var is_chrome = navigator.userAgent.toLowerCase().indexOf('chrome') > -1; if(is_chrome){ $('.ifChrome').attr('style', 'display:block;'); $('.ifChrome').html($('noscript > div').html()); }; If they are using chrome, we want to display a div tag and show the HTML from a different div tag inside. <noscript> <div class="note"> Your browser does not properly support the WMD Markdown Editor.<br /> Please use <a href="/about/markdown" target="_blank">Markdown<.a> to style your input. </div> </noscript> <div class="hidden ifChrome note"></div> What I'm trying to do is show the "not supported" text from inside my <noscript> tag to users who are using google Chrome (because WMD Markdown doesn't work properly with Chrome). My existing Javascript is not working. Any help would be greatly appreciated.

• How to enable 'playback follows cursor' / 'skip silence' in itunes?

  - by xor_eq

  foobar has got two pretty simple, yet very useful features (at least for me) that iTunes seems to be lacking: Playback follows cursor - Playback continues at the selected track Skip silence - Those 25 minute songs, containing 20 minutes of silence and then some final brainfart that's called "hidden track"... this feature just skips the silence, plays the final bit and continues with the next song Is it possible somehow to enable those features in iTunes?

• Using 'Copy as cURL' from Chrome in windows command line

  - by user2029890

  So, Google Chrome as this great 'copy as cURL' option under 'Network' of the Chrome DevTools. Works great in command lines for linux but not in windows. Apparently it has something to do with the single quotes as the error I get is protocol 'http not supported In other words its reading that single quote. Is there a simple way to make this formatable for windows? I tried replacing all the single quotes with double quotes but then nothing happens at all. The command is: curl 'http://www.test.com/login/' -H 'Cookie: PHPSESSID=7dvb25maaaaaa9d7bbbbbc3f6' -H 'Origin: http://www.test.com' -H 'Accept-Encoding: gzip,deflate,sdch' -H 'Host: www.test.com' -H 'Accept-Language: en-US,en;q=0.8' -H 'User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.36' -H 'Content-Type: application/x-www-form-urlencoded' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8' -H 'Cache-Control: max-age=0' -H 'Referer: http://www.test.com/login/' -H 'Connection: keep-alive' --data 'loc=&login=user%40test.com&password=password&submit1=Sign+In' --compressed Thank you

  Here's the example: http://jsfiddle.net/sammy/RubNy/ Scroll down in the div container. Then click anywhere in the window to hide the element. Then click once more to show the element. You'll notice in Chrome/IE that the scroll is reset, but in Firefox, the scroll remains how you left it. Which is the standards behavior, Chrome/IE or Firefox? Should I report this to the Chrome issue tracker? Thanks in advance for any help on this, and happy new year, and thanks again, and cheers, and stuff. =D

• JQuery div tag has children in FireFox but not Chrome

  - by John Edwards

  I am using JQuery ajax to load images from a url, display them, and then place a button on top of each image. The code works in firefox, but in chrome, the div parent "photos" that should have all the children(one child div "photo" for each image received from the url) is 0. I have tried read() and load(), but nothing seems to work. If I run alert($('#photos').children().size()); in the Chrome console it returns the children. But at execution it returns 0. Any ideas? $(window).load(function () { $("p").text("The DOM is now loaded and can be manipulated."); //returns 0 in chrome, but 10 in firefox alert($('#photos').children().size()); $('#photos').children().each(function() { //do stuff

• DIV appear differently in chrome only.

  - by DreamWave

  I have a website at bgflirt.com that appears differently in FireFox and Chrome. This is how it looks in firefox: and here's how it looks in chrome: As you can see, in chrome (and safari) the page is not stretched to fit the entire screen. I'm using this code for positioning the div containing the flash on the right: <div style="width: 200px; position: absolute; right: 0px; top: 10px; overflow: hidden;"> </div> The page should look the way it does in firefox, in all browsers. Any ideas on how to fix this will be greatly appreciated !

  How can I get the Google Chrome web browser on my TV for under $100? ($200 MAX) I have a TV with HDMI and component inputs (but no bluetooth so firmware modding is out.) I want the solution to work with bluetooth peripherals--I already have a wireless Apple keyboard and Magic Mouse. I don't want a laptop or a desktop computer, unless it's in the general form factor of an HTPC or Mac Mini. Is there a way to make this happen?
