• Determine web page draw time via a program

  - by Kevin Burke

  Google Chrome has a nice tool to determine the time the page begins drawing, in the Network tab in Developer Tools. Similarly sites like webpagetest.org can tell you the draw time and give you the whole waterfall of page loads for a given web page. I was wondering if I could automate the process of finding the time it took to the first page draw, for all of the pages on my site, so I can share this data within my company. Obviously the page draw time will depend on the latency and throughput of your connection, but I'm more concerned with the relative data about pages on our site. Can I get this data from Selenium or another tool? Thanks, Kevin

• Why do [flush-8:16] and [jbd2/sdb2-8] occasionally use 99.99% disk IO?

  - by ændrük

  Approximately twice a week, the entire graphical interface will lock up for about 10-20 seconds without warning while I am doing simple tasks such as browsing the web or writing a paper. When this happens, GUI elements do not respond to mouse or keyboard input, and the System Monitor applet displays 100% IOWait processor usage. Today, I finally happened to have GNOME Terminal already open when the problem started. Despite other applications such as Google Chrome, Firefox, GNOME Do, and GNOME Panel being unresponsive, the terminal was usable. I ran iotop and observed that commands named [flush-8:16] and [jbd2/sdb2-8] were alternately using 99.99% IO. What are these, and how can I prevent them from causing GUI unresponsiveness? Here is dumpe2fs /dev/sdb2, if it's relevant.

• GWT - How to define a Widget outside layout hierarchy in uibinder xml file

  - by mr_room

  Hello, this is my first post. I hope someone could help me. I'm looking for a way to define a widget in UiBinder XML layout file separately, without being part of the layout hierachy. Here's a small example: <ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" xmlns:g="urn:import:com.google.gwt.user.client.ui"> <g:Label ui:field="testlabel" text="Hallo" /> <g:HTMLPanel> ... </g:HTMLPanel> The compile fails since the ui:UiBinder element expects only one child element. In Java Code i will access and bind the Label widget as usual: @UiField Label testlabel; For example, this could be useful when you define a Grid or FlexTable - i want to define the Labels for the table header within the XML layout file, not programmatically within the code. Many thanks in advance

• How to tell the Browser the character encoding of a HTML website regardless of Server Content.-Type Headers?

  - by hakre

  I have a HTML page that correctly (the encoding of the physical on disk matches it) announces it's Content-Type: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv="Content-Type" content= "text/html; charset=utf-8"> <title> ... Opening the file from disk in browser (Google Chrome, Firefox) works fine. Requesting it via HTTP, the webserver sends a different Content-Type header: $ curl -I http:/example.com/file.html HTTP/1.1 200 OK Date: Fri, 19 Oct 2012 10:57:13 GMT ... Content-Type: text/html; charset=ISO-8859-1 (see last line). The browser then uses ISO-8859-1 to display which is an unwanted result. Is there a common way to override the server headers send to the browser from within the HTML document?

• How to implement SAML SSO

  - by A_M

  How is SAML SSO typically implemented? I've read this about using SAML with Google Apps, and the wikipedia entry on SAML. The wikipedia entry talks about responding with forms containing details of the SAMLRequest and SAMLResponse. Does this mean that the user has to physically submit the form in order to proceed with the single sign on? The google entry talks about using redirects, which seems more seemless to me. However, it also talks about using a form for the response which the user must submit (although it does talk about using JavaScript to automatically submit the form). Is this the standard way of doing this? Using redirects and JavaScript for form submission? Does anyone know of any other good resources about how to go about implementing SSO between a Windows Domain and a J2EE web application. The web application is on a separate network/domain. My client wants to use CA Siteminder (with SAML).

• How do I install pepper-flash on Chromium?

  - by user209900

  I have Chromium web browser on my Lubuntu 13.04 (pre-installed). I use LX Terminal (pre-installed) to write commands. I am trying to download flash player on Chromium using instructions on this site : sudo add-apt-repository ppa:skunk/pepper-flash After typing in my password, this worked. Now sudo apt-get update I didn't need to type in my password, as I continued on the same terminal, but got W:/ and E:/ fetch file errors sudo apt-get install pepflashplugin-installer I continued on the same terminal despite the fetch file errors... and they said pepflashplugin-installer could not be found. Is the last error because of fetch file errors, or because I need to download pepflash-plugin-installer somewhere? Or is it because of something else? I cannot download the Chrome browser, and not looking to use flash player on my Firefox web browser (installed using lubuntu software centre).

• How to geocoding big number of addresses?

  - by user308569

  I need to geocode, i.e. translate street address to latitude,longitude for ~8,000 street addresses. I am using both Yahoo and Google geocoding engines at http://www.gpsvisualizer.com/geocoder/, and found out that for a big number of addresses those engines (one of them or both) either could not perform geocoding (i.e.return latitude=0,longitude=0), or return wrong coordinates (incl. cases when Yahoo and Google give different results). What is the best way to handle this problem? Which engine is (usually) more accurate? I would appreciate any thoughts, suggestions, ideas from people who had previous experience with this kind of task.

• Where is a good place for a code review?

  - by Carlos Nunez

  Hi, all! A few colleagues and I created a simple packet capturing application based on libpcap, GTK+ and sqlite as a project for a Networks Engineering course at our university. While it (mostly) works, I am trying to improve my programming skills and would appreciate it if members of the community could look at what we've put together. Is this a good place to ask for such a review? If not, what are good sites I can throw this question up on? The source code is hosted by Google Code (http://code.google.com/p/nbfm-sniffer) and an executable is available for download (Windows only, though it does compile on Linux and should compile on OS X Leopard as well provided one has gtk+ SDK installed). Thanks, everyone! -Carlos Nunez

• How to use V8's built in functions

  - by Victor jiang

  I'm new in both javascript and V8. According to Google's Embedder's Guide, I saw something in the context section talking about built-in utility javascript functions. And I also found some .js files(e.g. math.js) in the downloaded source code, so I tried to write a simple program to call functions in these files, but I failed. Does a context created by Persistent<Context> context = Context::New() have any built-in js functions? How can I access them? Is there a way to first import existing js files as a library(something like src="xxx" type="text/javascript" in HTML page) and then run my own execute script? Can I call google maps api through the embedded V8 library in app? How?

• ruby xmpfilter on windows

  - by dreftymac

  Has anyone out there ever gotten xmpfilter to work on windows? xmpfilter "unterminated string meets end of file" is the error. The only Google hit is in Japanese: google://xmpfilter "unterminated string meets end of file" http://www.unkar.org/read/pc12.2ch.net/tech/1249687283 For background, the desired feature from xmpfilter is to get automatic "eval" annotations of Ruby sourcecode: Before: a = "bravo alpha charlie" # => b = a.split # => b.sort! # => After: a = "bravo alpha charlie" # => "bravo alpha charlie" b = a.split # => ["bravo", "alpha", "charlie"] b.sort! # => ["alpha", "bravo", "charlie"]

• Finding an alert in the middle of your javascript

  - by Ariel Popovsky

  I was debugging a script injection issue the other day using some sample code with an alert in it. The alert was popping out meaning the code got executed leaving open the possibility for a hacker to put there some nasty malicious code. I knew my alert was being executed but didn’t know how. So I tried something that worked perfectly for this problem, replaced the native alert function with my own one. All I had to do in Chrome was open the javascript console and type: alert = function(msg){ console.log(msg); console.trace(); }; The next time the malicious code was executed, instead of the regular alert I got something similar to this:   alert("testing") testing console.trace() alert:2 (anonymous function):2 InjectedScript._evaluateOn:312 InjectedScript._evaluateAndWrap:294 InjectedScript.evaluate:288 undefined In my case I was able to see what was going on and find the offending function. This was tested on Firebug in Firefox and it works as.

However I want to eliminate all the urls ending with .dtd . How do I do that? Note that I am saying ending with .dtd should be removed. It means a url like http://a.dtd.google.com should pass .

• Correct install of Android SDK, ADT with Eclipse 3.6.1

  - by macombej

  Following the posted instructions for Eclipse 3.6.1 Classic and Android SDK, ADT (where OS 2.3 is the most current) misses a few steps. Everything seems to work up until the point of loading the ADT in Eclipse. Prior to doing this add the following dependency sites to the list and enable them so that the ADT installer will pickup all the dependencies (thanks MissKaho for the concise list).

• Horizontal "tab"ish scroll between views

  - by Steve Pomeroy

  I'm interested in creating a horizontal scroll view that "snaps" to the viewed item, so only one item is ever shown at a time. The user can touch-drag left/right and will see previous/next views, switching to it if there's enough velocity. This interaction is exactly like what the new weather/news widget that comes with the Nexus One does for navigating between its "tabs". Are there any existing view widgets that do this? Update: found a copy of the news/weather widget (GenieWidget) and they seem to have implemented their own widget to accomplish this which they call com.google.android.apps.genie.geniewidget.ui.FlingableLinearLayout which is part of their own custom com.google.android.apps.genie.geniewidget.ui.TabView. As that source isn't available, that's not looking too hopeful a direction.

• Ubuntu DVD for Africa

  I live in Tanzania Africa and have been promoting Ubuntu for use by NGOs, Schools, and Friends. So far I've got a lot of positive feedback, but do have one huge problem. Internet here is both slow and very costly (up to $1,200 per month) So what I am looking for is a current release of Ubuntu which includes all the updates and popular applications already on it like; Gimp, VLC, Ubuntu Restricted files, Scribus, Inkscape, VirtualBox, Chrome, Audacity, Compiz, Blender, Ubuntu Tweak, Gnucash, Skype, etc... Basically all the 4 - 5 star applications. Does a hybrid DVD exist? I found links to one called Ubuntu Install Box 11.04, but not sure if they are truly legitimate. Any help would be greatly appreciated. Brendon

• IIS7 Serving .mp4s, not playable on iOS devices.

  I've added the proper MIME type to the server, made sure it applies to not only the specific site but even the all of server's sites. The file is accessible and playable in my browser (Chrome) but when trying to pull it up on an iPhone , the debug mode warns me that the "movie could not be played" but on iPad it's "byte_range_error_message" I'm really at a loss here of why iOS devices won't load the video up. I know it's not the video files themselves because I had used the same file on a different server (on a shared hosting package). Any help is appreciated! -Dan
