• Unable to connect to iFolder server

  - by Sven

  I tried to install iFolder on Ubuntu 10.10 server 64 bit using this guide. Everything "worked" except: If I try to acccess the server with http://myurl/admin I get the error-message "Unable to connect to the iFolder server." Has anyone succeeded with this guide, or is there an iFolder specialist who could help me with the last steps? Update 1: I could connect to the /admin-Interface by not changin anything in the config-script. Changing the ServerName in anything else than localhost brings back the error. And changing username and/or password has no affect.

• iOS 5 fixed positioning and virtual keyboard

  - by jeffc

  I have a mobile website which has a div pinned to the bottom of the screen via position:fixed. All works fine in iOS 5 (I'm testing on an iPod Touch) until I'm on a page with a form. When I tap into an input field and the virtual keyboard appears, suddenly the fixed position of my div is lost. The div now scrolls with the page as long as the keyboard is visible. Once I click Done to close the keyboard, the div reverts to its position at the bottom of the screen and obeys the position:fixed rule. Has anyone else experienced this sort of behavior? Is this expected? Thanks.

• Best solution for a team home server

  - by aliasbody

  I created a home server with Ubuntu 12.04 Server (using an old Netbook with an Atom CPU and 512Mb). The idea is just to be used for a small team (maximum 10 persons) that will have constant access by SSH to the main projects and could add features with Git, and will, as well, have their own directory (with VirtualHost configured) for their own personal projects. Everything is configured and running, but my question is : What is the best solution here for everyone to work? It is to have them on the http group and then all have access as normal users to the /var/www folder (that also contains GitWeb and Drupal), or would be to create a new user named after the project (as an example) where only those with the password could have access to work (configured with VirtualHost). Notice: The idea is to have 1 person responsible of the server directly (since he is the one who is hosting it), 2 more people that will have access to the root from their home in order to configure anything from their home, plus anyone else that joins the group without any root access, but just the necessary access to create personal works and work with Git.

• SQL Server join and wildcards

  - by Ernst

  I want to get the results of a left join between two tables, with both having a column of the same name, the column on which I join. The following query is seen as valid by the import/export wizard in SQL Server, but it always gives an error. I have some more conditions, so the size wouldn't be too much. We're using SQL Server 2000 iirc and since we're using an externally developed program to interact with the database (except for some information we can't retrieve that way), we can not simply change the column name. SELECT table1.*, table2.* FROM table1 LEFT JOIN table2 ON table1.samename = table2.samename At least, I think the column name is the problem, or am I doing something else wrong?

• adjust resolution on Ubuntu Server 10.04?

  - by Mike Grace

  Installed Ubuntu Server 10.04 on an old laptop and I noticed that the system is trying to show the CLI below my screen. This means that if I run a script or a program with a bunch of output, once it is done, I have to press return several times to bring the output to the point where I can actually see it on the screen. I also have to clear the screen to be able to see what I am typing at the current command prompt. The laptop is an EliteGroup 536S with a native screen resolution of 1024 x 768 How can I adjust the resolution for Ubuntu Server 10.04? What file do I need to edit if editing a file is the solution? I've seen posts on how to change the resolution on the desktop version of Ubuntu but not the server version.

• SQL Server ORDER BY/WHERE with nested select

  - by Echilon

  I'm trying to get SQL Server to order by a column from a nested select. I know this isn't the best way of doing this but it needs to be done. I have two tables, Bookings and BookingItems. BookingItems contains StartDate and EndDate fields, and there can be multiple BookingItems on a Booking. I need to find the earliest startdate and latest end date from BookingItems, then filter and sort by these values. I've tried with a nested select, but when I try to use one of the selected columns in a WHERE or ORDER BY, I get an "Invalid Column Name". SELECT b.*, (SELECT COUNT(*) FROM bookingitems i WHERE b.BookingID = i.BookingID) AS TotalRooms, (SELECT MIN(i.StartDate) FROM bookingitems i WHERE b.BookingID = i.BookingID) AS StartDate, (SELECT MAX(i.EndDate) FROM bookingitems i WHERE b.BookingID = i.BookingID) AS EndDate FROM bookings b LEFT JOIN customers c ON b.CustomerID = c.CustomerID WHERE StartDate >= '2010-01-01' Am I missing something about SQL ordering? I'm using SQL Server 2008.

• Minimum to install for a visual web browser in Ubuntu Server

  - by Svish

  I have set up a machine with Ubuntu Server. Some of the server software I want to run on it has web based user interfaces for setting it up et cetera. I know I could connect to it from a different machine which has a graphical user interface, but in this case I would rather do it on the box. So, from a fresh Ubuntu Server installation, what is the minimum I need to install to be able to launch a web browser I can use for this? For example chromium, firefox or arora.

• ASP.NET MVC thinks my virtual directory is a controller

  - by kmehta

  I have a virtual directory under my MVC website in IIS called "Files". This directory is at the same level as my Views directory. When I link to a file from my MVC app to a file under my Files directory, I get the following error: The controller for path '/Files/Images/1c7f7eb8-5d66-4bca-a73a-4ba6340a7805.JPG' was not found or does not implement IController. It thinks that my Files VD is a controller. How do I access my files like a normal VD without MVC interfering? Thanks.

• NTFS-compressing Virtual PC disks (on host and/or guest)

  - by nlawalker

  I'm hoping someone here can answer these definitively: Does putting a VHD file in an NTFS-compressed folder on the host improve performance of the virtual machine, diminish performance, or neither? What about using NTFS compression within the guest? Does using compresssion on either the host or the guest lead to any problems like read or write errors? If I were to put a VHD in a compressed folder on the host, would I benefit from compacting it? I've seen references to using NTFS compression on quite a few VPC "tips and tricks" blog posts, and it seems like half of them say to never do it and the other half say that not only does it save disk space but it actually can improve performance if you have a fast CPU and your primary performance bottleneck is the disk.

• Application loses authentication when performing redirect to a virtual directory

  - by nuhusky2003

  I have the following setup: http://www.example.com/dir1/ and http://www.example.com/dir2/ Each virtual directory is configured on IIS6.0 as an application with own AppPool. When redirecting authenticated user from dir1 to dir2 using response.redirect I lose authentication information for the user and the user is being redirected to the login page. This issue was not coming up with each app (dir1 and dir2) were configured under subdomain, ex: http://dir1.example.com and http://dir2.example.com. I have resolved the issue by adding a machine key to the machine.config file. Can someone explain to me why it's not working on a http://www.example.com/dir1 configuration?

• SQL Server 2012 Cumulative Update #1 is available!

  - by AaronBertrand

  While I joked earlier this month that SQL Server 2012 Service Pack 1 was released on the same day as General Availability (hey, it's Microsoft's fault since they decided to GA on April 1), this time it isn't a joke. Today Microsoft has released Cumulative Update #1 for SQL Server 2012 . About half of the fixes affect the database engine. Analysis Services and Data Quality Services make up the bulk of the remainder. If you're running SQL Server 2012 now, I suggest you apply the update. This would...(read more)

• Unwanted virtual keyboard in Blackberry app

  - by matkas

  I have developed a Blackberry app for the 4.5 os series. It works fine on all device except on the storm 1 (storm2 untested). The problem (on the storm) is that the main screen of my application (and all other screens in fact) is shown with the virtual keybord. But there is no text field displayed on the screen that would justify the VK to show up. I have bitmap fields and button fields only on that screen. The use of a single program for all devices (4.5 and up) is seriously preferred. What is causing the VK to show up and what can I do to prevent it (in JDE 4.5)?

• Java on Ubuntu server 12.04?

  - by Sean Dunwoody

  I'm a little confused at the moment. My back story in short, is that I'm trying to set up a Minecraft server on an Ubuntu server I've recently set up, obviously to do this I needed Java, but after googling for a short while I wasn't entirely sure whether it is possible (or legal?) to do so in Ubuntu 12.04 due to licensing type issues - so I installed open JDK instead which appears not to work properly with the Minecraft server software (I half expected this) I'm now considering uninstalling open JDK and instead trying to get proper Java on there instead, my question is, is this possible? Is it Legal? And if so how do I go about doing it? Because I'm finding it very difficult to find any instructions on how to do so for 12.04 . . .

• asp.net Web server control with child controls, event not firing

  - by bleeeah

  I have a simple web control (TaskList) that can have children (Task) which inherit from LinkButton, that can be added declaratively or programatically. This works ok, but I can't get the onclick event of a Task to be fired in my code behind. The code ..
