  • what's the javascript "var _gaq = _gaq || []; " for ?

    - by parvas
    The Async Tracking in google analytics looks like this: var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-XXXXX-X']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })(); About The first line var _gaq = _gaq || []; I think it ensures that if _gaq is already defined we should use it otherwise we should an array. Can anybody explain what this is for ? Also, does it matter if _gaq gets renamed ? in other words does google analytics rely on a global object named _gaq ? Thanks Parvas

  • Should I use Ruby version 1.8.7 or 1.9.2 to start developing Rails apps?

    - by BeachRunnerJoe
    Hello. I'm diving into RoR and I see that the current version of Rails (3.0.5) works with both 1.8.7 and 1.9.2. Currently, I have both versions of Ruby installed using RVM, but I'm wondering which version I should be using as I dive into Rails and start developing apps. I suppose I'd prefer to use the newest version (1.9.2), but I don't know the technologies well enough to know pros/cons of using either. Thanks so much!

  • Which is the best method to install/uninstall apps in Ubuntu?

    - by Mujahid
    While apps can be installed with the apt-get command, Synaptic Package Manager or Ubuntu Software Centre, can anybody throw some light on which is the best method? I recently installed kubuntu-desktop and as a result even Ubuntu Software Centre showed that it was installed. When I tried uninstalling it with Ubuntu Software Centre, the package didn't actually uninstall until I used Synaptic once again.

  • How Google Web Starter Kit serves adaptive image for mobile?

    - by 5argon
    My website weirdly (in a good way) serves smaller images when viewed on mobile. I wanted to know what cause this? As far as I know this is not the default behaviour, so I think it must be Google Web Starter Kit's doing.Here is the debug information when debugging on device. All images became 231 B size no matter how large it actually is. (On desktop debugging the size varies.) I tried using Google Web Starter Kit (https://github.com/google/web-starter-kit) recently. The tools in it are made of Ruby, Node.js, SASS and Gulp to help you 'build' website. Pre-build you can enjoy automatic reload because the Gulp script will watch all files for you. When build it will run various tools to minify HTML,CSS and compress images. According to this page https://developers.google.com/web/fundamentals/tools/build/build_site the gulp-imagemin was used. So I guess the imagemin is doing the mobile optimization for me? What kind of compression can serve automatically resized image on mobile? And why is the size 231 B? Is this related to my screen size?

  • Chrome does not re-draw properly on Windows 8

    - by Akshat Mittal
    There are a lot of problems with Chrome (24.0.1312.14 beta || But all this happened before update also) on Windows 8. Problems and explanations are listed below: Google Chrome re-draw time: When I switch tabs, the window retains the content of the previous tab and displays that even if I move my mouse, if only refreshes (re-draws) when there is a change on the webpage (like on hover) or I do a select all (or scroll). One thing to note is that the hover and select happens on the real page and not the retained image-like thing of the older webpage. Chrome is slow and laggy: Websites such as Facebook and Twitter (and more) have gone extremely laggy on Chrome (Win 8). When I was using Windows 7, I never experienced a lag or something. Also when using HTML-5 Websites, the transition (the -webkit-transition in CSS) goes extremely slow at times. Plugins Crash: Plugins like Flash Player, Shockwave Player, and more that are in-built into Chrome Crashes a lot, even when doing simple tasks like playing YouTube Videos, displaying ads or something. Chrome Crashes: Chrome has crashed over 100 times in the past month. Google Chrome just crashes randomly or I don't know the reason. Random Page crashes: Chrome results chrome://crash/(Copy-Paste this in address bar) on random pages even when the page is just loaded, I understand that this can happen on heavy HTML5 or JS websites but what about HTML only websites? Computer Freeze: Chrome sometimes, randomly, freezes my computer. Freeze in the sense, none of the other apps are also working. It's like the whole system freezes, I can not even switch to other apps. I am sure that this is because of Chrome since this happens only when Chrome is active. Most of the things above happens on Super User also, Super User never had any problem when using Chrome on Windows 7. UPDATE 1: @magicandre1981 Commented for trying to disable Hardware Acceleration. I tried it, it somewhat solved the problem but din't fix it. I am still experiencing all the above issues but less frequently (maybe because Chrome Restarted Completely) UPDATE 2: @avirk asked me to try a Stable Version of Chrome and Firefox, I din't experience any lag in Firefox, a little (negligible) lag in Chrome 22 (Maybe because its a new copy of Chrome, I haven't used it much). UPDATE 3: @NothingsImpossible said that He is also experiencing the same problem on Windows Server 2008! This seams to be a major issue now. He also said that GPU load is also high at the same time! Even I saw the same thing. UPDATE 4: Recently, Chrome updated to v24 Stable (I am using stable from a long time now). I was experiencing this problem a lot less in Chrome 23, but this is back in Chrome 24. Seams like Chrome 24 is the most affected from this bug, as this same problem was high in Chrome 24 beta also. UPDATE 5: Chrome was updated to v25 Stable. This problem is 99% Gone, it is still there in 1% of the cases. One such example is when I leave chrome inactive for a while with a few tabs open, the tabs go black and no activity can get them back to active state. If I open a new tab, the new tab is OK but the others are still black, I need to close all those tabs. UPDATE 6: Chrome updated to v27 Stable channel, this problem is nearly gone. This does happen occasionally, but not as frequent as in earlier versions of Chrome. UPDATE 7: I am on Chrome v35.0.1916.114 Stable, Windows 8.1 Pro Update 1. Some of the other problems appears to be back. Chrome is slow and laggy again. Re-draw time is getting worse. Is anybody else experiencing such issues? Does anybody have a solution to any of these?

  • OAuth in Rails - google, twitter, facebook, connect for login like stackoverflow login

    - by Sam
    Rails has the rest autho plugin which works well but is there a solution for incorporating twitter, facebook, google, yahoo, etc... Seems like each on has its own plugin and demands and mixing them is going to be a mess. This is for logging in users like how Stackoverflow gets things done not for using the robust features of the APIs. What I want to do is do what stackoverflow did for login but in rails.

  • Thrift / Google Protocol Buffers on Windows

    - by S73417H
    Hi All, Looking at Thrift and Google Protocol Buffers to implement some quick RPC code. Thrift would be perfect if the generated C++ code compiled on windows (which is what I need). And of course, GPB creates RPC stubs, but no implementation. Is there a way to get Thrift Windows friendly? Or, even better, are there any RPC implementations available freely for generated C++ protobuf stubs (a Java counterpart would be nice too, but is not necessary). Thanks

  • Google API to check number of indexed pages?

    - by Probocop
    Is there a Google API similar to Yahoo and Bing's API's to check for the number of indexed pages on a specified domain? For example, for Yahoo if I type in the following URL: http://search.yahooapis.com/SiteExplorerService/V1/pageData?appid=MTSlade&query=http://www.dave-sellers.co.uk&domain_only=1&results=1 Then it will return some XML detailing the number of pages indexed as 'totalResultsAvailable' Any idea? Thanks

  • "Android 2.x" vs "Google APIs" for Android AVD Setup

    - by Adam Haile
    In the Android AVD manager (or a new project for that matter), it will give two options for the same API level. For example, for Level 7 (2.1) it will show "Google APIs - Level 7" and "Android 2.1 - Level 7" in the selection drop down. What, if any, is the actual difference between these two and why would I want one over the other?

  • Google gadget to read https rss feeds?

    - by Carl
    Anyone run across a Google Gadget RSS reader that can read https feeds? I haven't been able to find any, and I'm not sure if this is because a) I'm the only one that needs one and/or b) there is something nasty about the browser security model here that I'll find out if I try to roll my own. Thanks much in advance.

  • Javascript Uncaught Error: INDEX_SIZE_ERR: - Google Chrome - Canvas

    - by Gart
    I am drawing on a canvas with the following line: ctx.drawImage(compositeImage, 0, 0, image.width, image.height, i, j, scaledCompositeImageWidth, scaledCompositeImageHeight); This code has executed error free on Safari, Chrome, Firefox (and even IE using google's excanvas library). However, a recent update to Chrome now throws the following error: Uncaught Error: INDEX_SIZE_ERR: DOM Exception 1 This code often positions part or all of the drawn image OFF the canvas, anyone got any idea what's going on here?

  • Microsoft CDN for JQuery or Google CDN?

    Does it actually matter which CDN you use to link to your jquery file or any javascript file for that matter. Is one potentially faster than the other? What other factors could play a role in which cdn you decide to use? I know that Microsoft, Yahoo, and Google all have CDN's now.
