  • Certificate Authentication

    - by steve.mccall1
    Hi, I am currently working on deploying a website for staff to use remotely and would like to make sure it is secure. I was thinking would it be possible to set up some kind of certificate authentication where I would generate a certificate and install it on their laptop so they could access the website? I don't really want them to generate the certificates themselves though as that could easily go wrong. How easy / possible is this and how do I go about doing it? Thanks, Steve

  • Configuring zsh in OSX to auto start processes

    - by calumbrodie
    I've recently converted to using zsh instead of bash in OSX and was wondering if it is possible to do the following: When I launch my terminal I would like to start various tabs and have each tab run a different process e.g tailing logs, running ruby scripts etc. Currently I need to cmd+n multiple tabs and then manually start each process. While this doesn't take long I would like to be able to just launch my terminal and have these various tabs start and run those commands automatically. Is this possible?

  • HVM virtualization with PV drivers on XenServer

    - by Nathan
    Is it possible to create an HVM guest in XenServer 5.5 that uses PV drivers for disk and network without being fully paravirutalized? This should give me decent performance from the VM without having to jump through hoops to create a PV guest when a pre-built template doesn't exist. Since PV drivers exist for Windows, and XenServer provides templates for windows that use HVM virtualization this must be possible, I just don't see how to configure this myself.

  • Can I set up multiple accounts on DD-WRT? [closed]

    - by Greg Ros
    Possible Duplicate: Can I set up multiple accounts on DD-WRT? I want to set up multiple accounts on DD-WRT (accounts meaning, username-password pairs). Specifically, I want one to be used primarily for remote web management (though there is no reason to restrict the account to such). Is this possible? If so, how do I go about it? I'm running: Router Model TP-Link TL-WR1043ND Firmware Version DD-WRT v24-sp2 (08/07/10) std - build 14896

  • Redirect XMPP with DNS

    - by Andrew Koester
    Is it possible to redirect XMPP using DNS records? I have a domain hosted on a shared host that does not have Jabber support. If possible, I'd like to still have XMPP on this domain, but have it connect to another IP (configured to support the first domain) without user intervention. I'm using ejabberd on the second server, if that helps.

  • iPad app store visibility

    - by Jameson
    So I created my iPad app and submitted it to the store, the app is called photogoo. I now have the iPad and I am finding that it is not possible to browse to the app in any way, confirmed by the zero downloads from yesterday. It is only possible to find by searching.. I also noticed that the apps in entertainment were being listed alphabetically and stopped at "F" Am I really being excluded because my app starts with the letter "P" or is it possible there is some reason that I am not being listed under "all apps"?

  • Defragment a file or folder? Windows 7

    - by acidzombie24
    Is there a built-in way to defragment a folder? I am using VM Player so I would like my 3 GB disk image to be defragmented if possible. FYI my disk partition that the image lies in has 12 GB left and has roughly 90% of the disk used. I probably would not need a defrag but I would like to do it if it's possible.

  • Hiding privates from Javascript Intellisense

    - by Robert Koritnik
    Is it possible to hide certain functions/fields from displaying in javascript intellisense drop down list in Visual Studio 2008? Either by javascript documentaion XML of by naming privates in a certain way? I've seen <private /> in jquery vsdoc file that implies exactly this behaviour, but doesn't meet my expectations { __hiddenField: 0, /// <private /> increment: function(){ /// <summary>Increments a private variable</summary> __hiddenField++; } } But since fields can't contain documentation (because they have no body) they have to be documented at the top. But still doesn't work: { /// <field name="__hiddenField" type="Number" private="true">PRIVATE USE</field> __hiddenField: 0, increment: function(){ /// <summary>Increments a private variable</summary> __hiddenField++; } } Impossible is a perfectly possible answer and will be accepted if you have the knowledge that it's actually not possible.

  • How to set WCF threads to schedual differently

    - by Gilad
    Hi, I'm running a winservice that has 2 main objectives. Execute/Handle exposed webmethods. Run Inner processes that consume allot of CPU. The problem is that when I execute many inner processes |(as tasks) that are queued to the threadpool or taskpool, the execution of the webmethods takes much more time as WCF also queues its executions to the same threadpool. This even happens when setting the inner processes task priority to lowest and setting the webmethods thread priority to heights. I hoped that Framework 4.0 would improve this, and they have, but still it takes quite allot of time for the system to handle the WCF queued tasks if the CPU is handling other inner tasks. Is it possible to change the Threadpool that WCF uses to a different one? Is it possible to manually change the task queue (global task queue, local task queue). Is it possible to manually handle 2 task queues that behave differently ? Any help in the subject would be appropriated. Gilad.

  • Can I pass data via JQUERY to ASP.NET MVC controller action and have a view rendered in new browser

    - by Simon Lomax
    Hi, Can anyone advise if its possible to pass data via JQUERY to an ASP.NET MVC controller action and have a view rendered in new browser tab based on the model data passed to the action method. My scenario is that I have a Jqgrid populated with product info on a page. The user would tick the items in the grid that they would like a label produced for. After they've made their slection they would click a button and I would like (if possible) to render a view of that contains a label for each selected item and have the view render in a new browser tab. All the code to allow the selections and post the relevant data back to the action method is all working fine and I know its easy to use the Jquery $(selector).load() command to populate an element on the current page with the HTML returned from the action. But is it possible to populate an element on a page in a new browser tab. If it is how would I go about it? Hope this make sense.

    - by bporter
    In a Google Spreadsheet, is it possible to take the sum of only the colored cells in a column? I have a column of numbers, where I've changed the background color of some of the cells to blue. All of the other cells in the column have the regular white background. Is it possible to create a formula to add up only the colored cells in the column? Thanks so much!

  • Python-McNuggets problem

    - by challarao
    Hi! I am a student of IIIT.I am new to python.This question is one of the problems in my problem set.Please Help me writing program such as in what I should do it. Show that it is possible to buy exactly 50, 51, 52, 53, 54, and 55 McNuggets, by finding solutions to the Diophantine equation. You can solve this in your head, using paper and pencil, or writing a program. However you chose to solve this problem, list the combinations of 6, 9 and 20 packs of McNuggets you need to buy in order to get each of the exact amounts. Given that it is possible to buy sets of 50, 51, 52, 53, 54 or 55 McNuggets by combinations of 6, 9 and 20 packs, show that it is possible to buy 56, 57,..., 65 McNuggets. In other words, show how, given solutions for 50-55, one can derive solutions for 56-65 6a + 9b + 20c = n

  • Static initializer in Java

    - by Szere Dyeri
    My question is about one particular usage of static keyword. It is possible to use static keyword to cover a code block within a class which does not belong to any function. For example following code compiles: public class Test { private static final int a; static { a = 5; doSomething(a); } private static int doSomething(int x) { return (x+5); } } If you remove the static keyword it complains because the variable a is final. However it is possible to remove both final and static keywords and make it compile. It is confusing for me in both ways. How am I supposed to have a code section that does not belong to any method? How is it possible to invoke it? In general, what is the purpose of this usage? Or better, where can I find documentation about this?

  • Try-Catch-Throw in the same Java class

    - by Carlos
    Is it possible to catch a method in the current class the try-catch block is running on? for example: public static void arrayOutOfBoundsException(){ System.out.println("Array out of bounds"); } ..... public static void doingSomething(){ try { if(something[i] >= something_else); } catch (arrayOutOfBoundsException e) { System.out.println("Method Halted!, continuing doing the next thing"); } } If this is possible how will it be the correct way to call the catch method? If this is not possible, could anyone point me in the right direction, of how to stop an exception from halting my program execution in Java without having to create any new classes in the package, or fixing the code that produces ArrayOutOfBoundsException error. Thanks in Advance, A Java Rookie

  • How to find connected hosts at network (vpn or lan)

    - by Javier Novoa C.
    Hello, I'm looking for possible solutions to the following need: I have a VPN configured (using openVPN over Linux, BTW), and I want to know at any moment which hosts are connected to it. I recognize that it probably is the same thing as trying to know which hosts are connected to a lan, so any of the solutions might do the job... The fact is that I once used a hamachi vpn on linux and with it I had the chance to know which hosts were connected to a particular network where I belonged, so I was wondering if something similar might be possible in openVPN (or even any VPN and/or any LAN). Preferably, I'm looking for opensource/free sw solutions, or maybe the hints to program it myself (in the most simple way if possible, not that I don't know how to program, but I'm trying to achieve this in a simple manner). But anyway, if there are no os/fsw solutions, any other one might do... Thanks a lot! Javier, Mexico city

  • Live video streaming using progressive download (and not RTMP) in Flash

    - by bartekb
    Hi, Is it possible to use progressive download for near real-time playback of a live video stream recorded with a webcam? What I need is that a video stream is recorded on one end, uploaded in real-time to a server and downloaded with a short delay, but in real-time, using progressive download (i.e., HTTP streaming) on another end for playback. Is it possible or does it require the use of RTMP? If it's possible, then does it require that Flash Media Server runs on a server? Thanks!

  • How to efficiently track my geolocation during traveling using iPhone

    - by Peter Kruithof
    I'm going to travel through Thailand and I want to keep track of my location to geotag photos afterwards taken with a digital camera (iPhone's camera is not good enough). There are two things that are important here: I don't want to update manually I want the battery to last as long as possible, since the times I will be able to charge will be scarce I've thought about creating a web page that periodically sends my geolocation to a script that stores it in a database, but I don't know if GPS data is available in Mobile Safari. Second, I want the data I send to be as small as possible, and the frequency this is done s few as possible, because of the pricing of mobile data usage abroad. Any suggestions what would be a good solution here?

  • Rails web app authenticated with windows

    - by deostroll
    Is it possible for a rails web application to make use of the windows authentication features in its code. I am looking at being able to obtain the user's login name and domain in the application. But there is a catch. This particular web application runs off an apache web server hosted on a linux machine which is kind of networked to other windows machines. Is all of this possible?
