  • Is there a way to get the uid of the other end of a unix socket connection

    - by yuyichao
    Is there a way for a unix socket listener to only accept connection from certain user (chmod/chown does not work for abstract socket afaik), or in another word, get the uid of the incoming connection (on Linux)? Dbus, which uses abstract unix socket on Linux, has a function GetConnectionUnixUser which is used by polkit to determine the caller. So I suppose the dbus-daemon must have a way to do that. Does anyone know how that works? THX

  • Scala: can't write setter without getter?

    - by IttayD
    This works: class ButtonCountObserver { private var cnt = 0 // private field def count = cnt // reader method def count_=(newCount: Int) = cnt = newCount // writer method // ... } val b = new ButtonCountObserver b.count = 0 But this doesn't class ButtonCountObserver { private var cnt = 0 // private field def count_=(newCount: Int) = cnt = newCount // writer method // ... } val b = new ButtonCountObserver b.count = 0 I get: error: value count is not a member of ButtonCountObserver Is it possible to create a setter (with the syntactic sugar) without a getter?

  • TextImageRelation Implementation

    - by BobPelotas
    Hello, Does anyone know any information on implementing the TextImageRelation property on a button? Since it is impossible to paint a custom background without having to also paint the foreground, I need at least an idea of how the algorithm works. I can't find any info on it. Thanks

  • Help with HQL Query (find duplicates)

    - by BRhodes
    I am trying to convert this native sql into an HQL query. Basically it returns all the contacts that are duplicates (by company, firstname, and lastname). The query below works great, but performing a joined subselect seems impossible in HQL is it not?! Select c.* from contact c join ( Select c2.* from contact c2 group by c2.company, c2.firstname, c2.lastname, c2.teamId having count(c2.contactId)1 and teamId=1 ) dupes on c.company=dupes.company and c.teamId=1 and c.firstname=dupes.firstname and c.lastname=dupes.lastname order by c.company, c.firstname, c.lastname

  • Java, let CookieHandler work on only one instance.

    - by user435657
    Hi all, I don't know how CookieHandler works system wide, I did view the source of CookieHandler but found no more information except the get/set methods. Where do TCP/HTTP connections use instance of CookieHandler, which I set by CookieHandler.setDefault(...) Which source file I should refer to? URLConnection & HttpURLConnection don't seem have things to do with it. Help, thanks in advance.

  • Makefile - How to save the .o one directory up?

    - by nunos
    Imagine the following folder structure: project src code.c makefile bin How can I compile code.c to code.o and directly put it inside bin? I know I could compile it to code.o under src and the do "mv code.o ../bin" but that would yield an error if there were compile errors, right? Even if it works that way, is there a better way to do it? Thanks.

    Hi All, I have successfully signed my elevated trust xap file with a cert bought from comodo. This works great on my local machine but when I transfer my xap to our server it is as if the xap had not been signed. Am I missing something that I need to do on the server to allow this to work? Thanks for any questions or input.

    - by Prithis
    Hi, As you are aware Oracle 11g has new facility of case sensitive password. We want to make use of it. When my C# application connects to oracle databse using ODP.Net 2.111.7.0 I am getting ora-1017 error. When we switch off this case sensitive feature it works without any change to the connection string. Any idea what is missing? is there any escape sequence we can use to specify lowercase characters in password? Thanks

  • jQuery: load refuses to get dynamic content in IE6

    - by user260157
    jQuery refuses to load my dynamic content in IE6. All in FireFox & Safari works fine. Only IE6 is being a pain. When I try the a html with <p>Hello World</p> that works. Properly. But when loading a PHP it doesn't work! As you can see it's doing multiple things. <script type="text/javascript"> // When the document is ready set up our sortable with it's inherant function(s) $(document).ready(function() { // Sort list & amend in database function sortTableMenuAndReload() { var order = $('#menuList').sortable('serialize'); $.post("PLUGINS/SortableMenu/process-sortable.php",order); $("#menuList").load("PLUGINS/SortableMenu/sortableMenu_ajax.php"); } function sortTableOrder() { var order = $('#menuList').sortable('serialize'); $.post("PLUGINS/SortableMenu/process-sortable.php",order); } function sortTableOrderAndRemove(removeID) { $('#listItem_'+removeID).remove(); var order = $('#menuList').sortable('serialize'); $.post("PLUGINS/SortableMenu/process-sortable.php",order); $("#menuList").load("PLUGINS/SortableMenu/sortableMenu_ajax.php"); } $("#menuList > li > .remove").live('click', function () { var removeID = $(this).attr('id'); $.ajax({ type: 'post', url: 'PLUGINS/SortableMenu/removeLine.php', data: 'id='+removeID, success: sortTableOrderAndRemove(removeID) }); }); $("#menuList > li > .publish").live('click', function () { var publishID = $(this).attr('id'); $.ajax({ type: 'post', url: 'PLUGINS/SortableMenu/publishLine.php', data: 'id='+publishID, success: sortTableOrder }); }); $('#new_documents > li').draggable({ addClasses: false, helper:'clone', connectToSortable:'#menuList' }); $("#menuList").droppable({ addClasses: false, drop: function() { var clone = $("#menuList > li#newArticleTYPE1"); $(clone).attr("id","listItem_newArticleTYPE1"); } }); $("#menuList").sortable({ opacity: 0.6, handle : '.handle, .remove', update : sortTableMenuAndReload }); }); </script>

  • jQuery UI problem: why do the elements go flying around the screen?

    - by George Edison
    Yes, I know the title sounds a little suspicious. I will try to explain this the best I can... The code below is supposed to have the blue div slide down beside the red div. The first time you hit the Show the div button, it works. Also, the Hide the div works. Then when I click to show the div again, it appears to the right of where it is supposed to be! Why is this?!? Note: You can find a live example of the code here <html> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Demo</title> <style type='text/css'> #red { background-color: red; width: 200px; height: 150px; position: absolute; } #blue { background-color: blue; width: 150px; height: 200px; position: absolute; display: none; } #tester_1 { top: 300px; left: 300px; position: absolute; } #tester_2 { top: 350px; left: 300px; position: absolute; } </style> </head> <script type="text/javascript" src="jquery.js"></script> <script type='text/javascript'> function Show() { $('#blue').position({ of: $('#red'), my: 'left top', at: 'right top'}).slideDown(); } function Hide() { $('#blue').hide(); } </script> <body> <div id='red'></div> <div id='blue'></div> <button id='tester_1' onclick='Show()'>Show the <kbd>div</kbd></button> <button id='tester_2' onclick='Hide()'>Hide the <kbd>div</kbd></button> </body> </html>

  • JQuery.ajax(): Problem with parameter data when consuming a WCF Service

    - by Torben H.
    Hello, I'm using JQuery to consume a WCF Service. Actually this works fine: var para = ' { "Parameter" : { "ID" : "5", "Name" : "Peter" } }' $.ajax({ type: "POST", contentType: "application/json", data: para, url: url success: success }); But I don't want to pass the data parameter as String and I think it should be possible to pass ist as array in any way. Like that: var para = { "Parameter" : { "ID" : 5, "Name" : "Peter" } } But when I try this I'm getting an error. What I'm doing wrong? Thanks

  • LaTeX verbatim that can break too long lines?

    - by kotlinski
    I want to generate a PDF of user-submitted text using LaTeX. To handle crazy user input, I first thought about using the verbatim package, but of course it doesn't break up too long lines. Is there some package that works similar to verbatim (i.e., accept any input) but formats the text nicely?
