  • What might make "Xclients" be executed twice when boot system?

    - by ablmf
    For some special purpose, I modified /etc/X11/xinit/Xclients to start firefox instead of start Desktop Environment. # Argh! Nothing good is installed. Fall back to twm { # gosh, neither fvwm95 nor fvwm2 is available; # fall back to failsafe settings [ -x /usr/bin/xsetroot ] && /usr/bin/xsetroot -solid '#222E45' # if [ -x /usr/bin/xclock ] ; then # /usr/bin/xclock -geometry 100x100-5+5 & # elif [ -x /usr/bin/xclock ] ; then # /usr/bin/xclock -geometry 100x100-5+5 & # fi # if [ -x /usr/bin/xterm ] ; then # /usr/bin/xterm -geometry 80x50-50+150 & # fi if [ -x /usr/bin/firefox ]; then /usr/bin/firefox -chrome http://127.0.0.1/ -width 1280 -height 768 fi # if [ -x /usr/bin/twm ] ; then # exec /usr/bin/twm # fi This used to work fine until today I tested it on another computer. Firefox reports that there's another running instance of firefox which stops responding. Thus, firefox could not autostart as I expected. I connected the computer with SSH and I found there are 2 firefox processes: [root@my113 xinit]# ps -ef | grep firefox root 4479 4371 0 17:34 ? 00:00:00 /bin/sh /usr/lib/firefox-3.0b5/run-mozilla.sh /usr/lib/firefox-3.0b5/firefox -chrome http://127.0.0.1/ -width 1280 -height 768 root 4600 4479 0 17:34 ? 00:00:01 /usr/lib/firefox-3.0b5/firefox -chrome http://127.0.0.1/ -width 1280 -height 768 root 4940 4906 0 17:35 ? 00:00:00 /bin/sh /usr/lib/firefox-3.0b5/run-mozilla.sh /usr/lib/firefox-3.0b5/firefox -chrome http://127.0.0.1/ -width 1280 -height 768 root 4963 4940 0 17:35 ? 00:00:00 /usr/lib/firefox-3.0b5/firefox -chrome http://127.0.0.1/ -width 1280 -height 768 root 5717 5345 0 17:51 pts/2 00:00:00 grep firefox I guess, for some reason, "Xclients" is executed twice. But I really knows very little about XWindows, so if anyone here could give me some clues, I will appreciate!

  • How to replace openSSL calls with C# code?

    - 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# code that doesn't depend on external programs. 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?

  • Accessing WebKit Devtools JavaScript library

    - by VLostBoy
    I noticed something in Chrome the other day- I had opened Developer Tools, and then hit view source and was initially surprised to notice that apparently the developer tools window is coded in HTML and JavaScript- you can see that by putting the following into the Chrome address bar: view-source:chrome://devtools/devtools.html Two things struck me- first, the codes copyright belongs to Apple (considering their backing of WebKit, thats not too surprising), and secondly, it appears that you cannot access the JavaScript, CSS or Image files directly through Chrome by clicking on links in the source code. So two questions: Where are the DevTools assets stored on my computer or how can I otherwise access them? Or even better, can someone identify the library that is used and let me know how its licensed? I'm always on the look out for a well implemented UI toolkit- and Devtools looks great.

  • How can a Firefox extension inject a local css file into a webpage?

    - by Evgeny Shadchnev
    I'm writing a Firefox extension that needs to inject a css file into webpages. The css file is bundled with the extension, so I can access it using a chrome url chrome://extensionid/content/skin/style.css I'm trying to inject css like this when the page is loaded: var fileref = document.createElement("link"); fileref.setAttribute("rel", "stylesheet"); fileref.setAttribute("type", "text/css"); fileref.setAttribute("href", "chrome://extensionid/content/skin/style.css"); document.getElementsByTagName("head")[0].appendChild(fileref); However, the css isn't loaded and Firebug shows 'Filtered chrome url' message instead of the file content, when I inspect the link element I created. If I try to load this css file from an external server, everything's fine. Is there are way to load a css file bundled with the extension?

  • Problem making local copy of a webpage

    - by Claudiu
    I want to run this chrome experiment locally. I copied the .html and .js files, along with the two .jpgs that the demo uses. However, when I run it off my local drive, Chrome gives this error: light.js:89 - Uncaught Error: SECURITY_ERR: DOM Exception 18 Line 89 returns the image data from the canvas after drawing the image to it. What's causing this security exception? It seems to not be Chrome-specific, as Firefox gives the same error.

  • Problems with GData Request Token

    - by Dan Delgado
    We have successfully used GData libraries to access a user's Google Docs. But we encountered problems when many users log in to our site and authorize our web app at the same time or successively. Here's what happens: First user successful logs in, authorizes our web app via OAuth and is able to add rubric (or google spreadsheet). Second user, immediately after first user adds a rubric, successfully logs in then webapp fails on authorize (Token not given. I tried to log it.) Third user fails on login. Fourth user was able to log in, authorize via OAuth, and create rubrics successfully. Fifth user was able to log in but like the second user, gets an invalid token on authorize (Token not given.) And the list goes on. Results were unpredicatable. Below is an excerpt of the stack trace we get when the fail scenario happens: Nested in org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.NullPointerException: java.lang.NullPointerException at com.google.gdata.client.authn.oauth.OAuthUtil.normalizeParameters(OAuthUtil.java:158) at com.google.gdata.client.authn.oauth.OAuthUtil.getSignatureBaseString(OAuthUtil.java:81) at com.google.gdata.client.authn.oauth.OAuthHelper.addCommonRequestParameters(OAuthHelper.java:649) at com.google.gdata.client.authn.oauth.OAuthHelper.getOAuthUrl(OAuthHelper.java:592) at com.google.gdata.client.authn.oauth.OAuthHelper.getUnauthorizedRequestToken(OAuthHelper.java:276) at com.projectrix.controller.OAuthController.authorize(OAuthController.java:59) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Method.java:40) Help!

  • How do I use Google's Gson API to deserialize JSON properly?

    - by FK82
    Hi, In short, this is a sketch of the JSON object I want to parse in JAVA: { object1: { item1: //[String | Array | Object] , item2: // ... //<> more items object2: { // } //<> more objects } These are the POJO s I created for parsing (I'll leave out the import statements for brevity's sake): (1) The representation of the complete JSON object public class JObjectContainer { private List<JObject> jObjects ; public JObjectContainer() { // } //get & set methods } (2) The representation of the nested objects: public class JObject { private String id ; private List<JNode> jObjects ; public JObject() { // } //get & set methods } (3) The representation of the items: public class JNode { private JsonElement item1 ; private JsonElement item2 ; //<> more item fields public JNode() { // } //get & set methods } Now, creating a Gson instance (FileReader for importing the jsonFile), Gson gson = new Gson() ; JObjectContainer joc = gson(jsonFile,JObjectContainer.class) ; I get a NullPointerException whenever I try to access the parseable object (e.g. through a ListIterator). Gson does however create an object of the class I specified and does not throw any subsequent errors. I know that this has been done before. So, what am I missing? TIA

  • What is Repo and Why does Google use it?

    - by Osama Gamal
    When I wanted to get Android source code, I knew that I have to use "repo". So what is repo? Why do they use repo and not just use GIT?, and is there a GUI for repo that enables me to pause/resume syncing, because every time I get disconnected occasionally it seems that repo starts syncing from the beginning!

  • Will news ticker using overflow:hidden cause Google to see site as spam?

    - by molipix
    In the hope of tempting Googlebot with fresh content, I've implemented a homepage news ticker which displays the 20 most recent headlines on our site. The implementation I have chosen is a <ul> with each headline being a <li> Initially all the <li> elements have no style but Javascript kicks in on page load and gives all but one of them a display="style:none" attribute. Javascript then displays each of the other 19 headlines in a loop. So far so good. However, in order to prevent a visually unplesant page load where the 20 items display and then immediately collapse, I am using overflow:hidden on the <ul> element. Anyone got a view on what Googlebot is likely to make of this? Does the fact that I'm using overflow:hidden make the content look like spam?

  • Assign click event to addon icon on navigation bar

    - by Charsee
    We have created a chrome extension for our app. Where we call a METHOD from a "js file" on CLICK event of the "extension icon" placed on the navigation bar. For this we use message passing between the app.js (file containing the METHOD to be called on icon click) and background.html (using a js file included in this html). The script used to pass message is:(from background.html) chrome.browserAction.onClicked.addListener(function (tab) { chrome.tabs.sendMessage(tab.id, "showPopup"); }); and to listen the message :(in app.js) chrome.extension.onMessage.addListener(function(request) { if (request === "showPopup") { showPopup(); } }); The click event works as expected. But now we want to do same thing in mozilla extension. and we can't pass message to app.js on the click of the icon,so that it can execute the containing methods. We have also added the app.js using pageMod, something like this exports.main = function(options, callbacks) { pageMod.PageMod({ include: ["*"], contentScriptWhen: 'start', contentScriptFile: [data.url('jquery-1.7.1.min.js'),data.url('app.js')] }); createAndAddNavBarButton(); }; function createAndAddNavBarButton() { var navBar = document.getElementById('nav-bar');//assume document has been defined if (!navBar){return;}; var nbBtn = document.createElement('navbaricon'); nbBtn.setAttribute('id', 'navButton'); nbBtn.setAttribute('image', data.url('icon_16.png')); nbBtn.onclick = function(){ showPopup(); return true; } navBar.appendChild(btn); } But the click event does nothing and showPopup() is undefined. When a new page loads event associated with it in the app.js executes without any error but the click event doesn't work. Is there a method from where we can assign click event directly to this icon, as we have done in the case of chrome extension.

  • Why is Firefox so bloated? [closed]

    - by bvandrunen
    First off I am a developer who loves firebug and other development tools (and no Chrome firebug lite does not cut it) and am just utterly frustrated when I have been using Firefox lately. It is at the point where I use Chrome for absolutely everything but web development but am still frustrated that I had to switch where half a year ago or more Firefox was fine. Why can't there be a Firefox lite? One that is free from all the bloat that has been plaguing Firefox recently. Also if there are any tools or tips that I can free up my Firefox that would be great. I am using the newest version + as few add-ons as possible. EDIT: I have tried Chrome Developer Tools and I do like them...but I can't get passed the firebug lite extension of Chrome. Some of the developer tools are great but sometimes they just have too much information. I extensively use Firebug/myphp admin. Both of these work much much better in Firefox then Chrome. But I hate that it takes me so much longer to load and use everything.

  • Custom onsynctopreference for XUL textbox

    - by Alexey Romanov
    I wanted to enable custom shortcuts in my Firefox extension. The idea is that the user just focuses on a textbox, presses key combination, and it's shown in the textbox and saved to a preference. However, I couldn't get it to work. With this XUL <?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> <?xml-stylesheet href="chrome://mozapps/skin/pref/pref.css" type="text/css"?> <!DOCTYPE window SYSTEM "chrome://nextplease/locale/nextplease.dtd"> <prefwindow id="nextpleaseprefs" title="&options.title;" buttons="accept, cancel" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <prefpane id="nextplease.general" label="&options.general.title;" image="chrome://nextplease/skin/Sound Mixer.png"> <preferences> <preference id="nextkey" name="nextplease.nextkey" type="int"/> </preferences> <vbox flex="1"> <hbox align="center"> <label value="&options.general.nextKey;" /> <textbox id="nextkey" flex="1" editable="false" onkeyup="return nextplease.handleKeySelection(this, event);" preference-editable="true" preference="nextkey" onsynctopreference="alert('syncing'); return nextplease.syncKeySelector(this);"/> </hbox> </vbox> </prefpane> <script type="application/x-javascript" src="chrome://nextplease/content/nextpleaseCommon.js" /> <script type="application/x-javascript" src="chrome://nextplease/content/nextpleaseOptions.js" /> </prefwindow> the event in onkeyup works. But when I click the OK button, I don't see a "syncing" alert. Why isn't onsynctopreference working? Is it impossible to have custom onsynctopreference attribute for a textbox?

  • How to (legitimately) access files after putting self into chrooted sandbox?

    - by unknown google user
    Changing a Linux C++ program which gives the user limited file access. Thus the program chroots itself to a sandbox with the files the user can get at. All worked well. Now, however, the program needs to access some files for its own needs (not the user's) but they are outside the sandbox. I know chroot allows access to files opened before the chroot but in this case the needed files could a few among many hundreds so it is obviously impractical to open them all just for the couple that might be required. Is there any way to get at the files?
