  • Open a file with su/sudo inside Emacs

    - by Chris Conway
    Suppose I want to open a file in an existing Emacs session using su or sudo, without dropping down to a shell and doing sudoedit or sudo emacs. One way to do this is (require 'tramp) C-c C-f /sudo::/path/to/file but this requires an expensive round-trip through SSH. Is there a more direct way? [EDIT] @JBB is right. I want to be able to invoke su/sudo to save as well as open. It would be OK (but not ideal) to re-authorize when saving. What I'm looking for is variations of find-file and save-buffer that can be "piped" through su/sudo.

  • How to keep an Hibernate's Session open until the page is rendered

    - by Neuquino
    I'm having the following problem: I'm using Oracle ADF for the view and controller of my app. With OpenSessionInViewFilter, I intercept the request and open an Hibernate's Session, and it is closed as soon as the bean's method finishes. What I need is to keep the Session opened until the page is rendered, because in my JSP y use the lazy attributes of the object i load from the DB. For example: When I enter index.jspx the IndexBean#main() is executed: public class IndexBean{ private DBObject myDBObject; public String main(){ this.myDBObject = this.myDAO.loadObjectFromDB(); return null; } } in index.jspx I have: ... <af:inputText value="#{myDBObject.lazyAttribute}" /> ... I'd like that the Hibernate's Session keeps open until the af:inputText is processed. Is this possible? How? Thanks in advance

  • Mac: Cannot open the parent directory Library

    - by rolandbishop
    I really am about to go crazy because nothing worked out. I'm trying to access the Library folder on my OS Lion however all the tutorials related to this subject involves opening the user library however I would like to access the Library where the 'WebServer' folder is located when you enable web-sharing. Whenever I try to access it it gives me the error that I am not allowed to see what's inside and I checked my status, saying that I am an admin but it still occurs. Any help?

  • Text Formatting toolbar continuously disappears in Impress (open office)

    - by Davide
    This is a very weird and annoying problem. Not sure if it's a bug or a "feature" I'm using OpenOffice 3.2 (within Ubuntu 10.04). The Text Formatting toolbars disappear in many circumstances, e.g. each time I click out of a writing area. It's becoming very time consuming to go to View-Toolbars-TextFormatting to re-enable it each time. 3 questions: is this expected behavior, and if so, is there any setting where I can change it? (note this wasn't happening in the past with other presentation I made)? is there a workaround, such as defining a shortcut like CTRL-whatever that would make the toolbar appearing without menu joggling? is anybody experiencing this too, especially someone using LibreOffice?

  • change browser to open weblinks in thunderbird

    - by Bevor
    Hello, because it's almost obvious that either Thunderbird or Firefox freeze my whole system after some time, I'd like to not use FF at the moment and let Thunderbird run only for a short time as long as I check e-mails. Thunderbird web links should be opened with opera from now. For that I went in Thunderbird to Preferences-Advanced-General-Config Editor and set the following: network.protocol-handler.app.http -> /usr/bin/opera network.protocol-handler.app.https -> /usr/bin/opera network.protocol-handler.warn-external.ftp -> true network.protocol-handler.warn-external.http -> true network.protocol-handler.warn-external.https -> true Moreover I changed in Gnome in System-Preferences-Prefered Applications Opera as webbrowser and I checked in FF that it should warn if FF is not the default browser (obviously it isn't anymore). Unfortunately all of these settings doesn't work. Thunderbird still opens web links with FF. Any explantions why? (I already restarted Thunderbird although I don't have to, but no effect)

  • Qmail & Open Relay on local domains

    - by Jonathan
    Hello. I have a dedicated server on 1&1 and I manage it with Plesk. The problem is that if I try to send a mail outside the server, I must to authenticate with the email and the password, but if I send an email to a address inside of my server I don't need neither email or password. This is a problem because the spammers are sending mails without any problem to the server accounts. We are receiving about 900 - 1200 emails everyday! What can I do? I use qmail on CentOS Thanks

  • accessing and modifying tab opened using window.open in google chrome

    - by sonofdelphi
    I used to be able to this to create an exported HTML page containing some data. But the code is not working with the latest version of Google Chrome (It works alright with Chrome 5.0.307.11 beta and all other major browsers). function createExport(text) { var target = window.open(); target.title = 'Memonaut - Exported View'; target.document.open(); target.document.write(text); target.document.close(); } Chrome now complains that the domains don't match and disallows the Javascript calls as unsafe. How can I access and modify the document of a newly opened browser-tab in such a scenario?

  • Open folder in new window in vista

    - by lagerdalek
    In XP, to ensure a folder opened in a new window, I held down CTRL when I opened (by mouse or keyboard) the folder. This action is so ingrained to me, I pretty much don't even realise I'm doing it at a conscious level. Unfortunately, this action apparently hasn't made it to Vista. Is there a new way to do this, or am I just missing something obvious?

  • Minimum Requirements for (open) Solaris?

    - by Electrons_Ahoy
    I'm thinking about knocking together a Solaris box at home to act as a combination server and learning exercise. What are the minimum hardware specs I can throw at it such that it'll be actually usable? I'd be cobbling the machine together from a stack of various x86 PC spares/leftovers. Does anyone have experience with Solaris at the lower end of the spectrum? The Sun site, for example, claims it'll run with as little as 255 megs of ram, but is it worth the exercise with less than a gig? Will my old Pentium II 450 cut the mustard? (I'm willing to throw a couple of bucks at pricewatch/mwave/newegg on this, but if I need to build a better rig than my main PC, I may not bother.)

  • Force applications to open in the foreground when launched from iexplore

    - by Earls
    I have a slight problem with my project I've working on... I have replaced explorer with iexplore in kiosk mode. iexplore loads a speeddial type of webpage for a set of windows programs. I launch those programs with PHP's system(). The problem is, when the programs launch, they launch BEHIND iexplore instead of in front of it. How can I force the programs being launched to ALWAYS load in the foreground?

  • Does an updated 'vimtutor' exist?

    - by Glennular
    vim comes with a nice built-in interactive tutorial. You can access this tutorial by just running: $ vimtutor It is very easy to use because it creates working cases for basic commands. Is there a more advanced tutorial? Has any one though to build one to help uses take their VIM skills to the next level. Most tutorial and cheat-sheet sites out there for vim only show commands but not necessarily specific uses and examples. Is there an advance tutorial out there? Is this the type of project that could be an open source document that everyone can add examples to? Like a Vim Interactive Wiki or similar to the RegEx sites that have the built in regex testers.

  • Keeping connection to APNs open on App Engine using Modules in Go

    - by user3727820
    I'm trying to implement iOS push notifications for a messageboard app I've written (so like notification for new message ect. ect.) but have no real idea where to start. Alot the current documentation seems to be out of date in regard to keeping persistent TLS connections open to the APNs from App Engine and links to articles about depreciated backends I'm using the Go runtime and just keep getting stuck. For instance, the creation of the socket connection to APNs requires a Context which can only be got from a HTTP request, but architecturally this doesn't seem to make a lot of sense because ideally the socket remains open regardless. Is there any clearer guides around that I'm missing or right now is it a better idea to setup a separate VPS or compute instance to handle it?

  • Unable to open a file for writing

    - by asdasdas
    I am trying to write to a file. I do a file_exists check on it before I do fopen and it returns true (the file does exist). However, the file fails this code and gives me the error every time: $handle = fopen($filename, 'w'); if($handle) { flock($handle, LOCK_EX); fwrite($handle, $contents); } else { echo 'ERROR: Unable to open the file for writing.',PHP_EOL; exit(); } flock($handle, LOCK_UN); fclose($handle); Is there a way I can get more specific error details as to why this file does not let me open it for writing? I know that the filename is legit, but for some reason it just wont let me write to it. I do have write permissions, I was able to write and write over another file.

  • XCode won't open: "Mac OS X platform is missing"

    - by Jan Hettich
    XCode won't open. I had it running fine a couple of weeks ago. Now I get the following error message when XCode tries to open: Internal Error File: /SourceCache/DevToolsBase/.../XCPlatformSpecification.m Line: 438 Object: <XCPlatformSp(ecification> Method: loadAllPlatforms The Mac OS X platform is missing - cannot set a default platform. Any idea what caused this or how I can recover? Changes I have made to my system (Snow Leopard) in the last couple of weeks include (a) allowing Software Update to run and (b) installing Eclipse IDE. But the problem may or may not be related to these changes.
