I just got Scott Hanselman's chat app with SignalR working with ASP.NET MVC 4. After hours of configuration, trial and error, and getting different versions of Windows to talk to each other on my home network, it's all working except that I'm left with one issue that I'm not sure how to handle.
This line of javascript has to change, depending on…
I have a table view with a list of categories and each category (understand table cell) has a different icon.
I would like to use one big image (sprite) and render different part of the image (single icon) for each row.
Any efficient ideas...
Hello,
I was wondering is there an easy way to communicate between iphones over the Internet(Not LAN/Bluetooth) or must there be a dedicated server in which all the iphones running an application needs to connect to?
For instance, suppose I'm writing a game which works on the Internet. Once four clients joins a room, game starts. must I…
Hi!
I used a western digital mybookworld (SOHO NAS storage using Linux) as backup for my Linux box. Suddenly, the mybookworld does not boot up any more. So I opened the box, removed the hard disk and put the hard disk into an external USB HDD case, and connected it to my Linux box.

I'm trying to budget for my dev shop and compare our budget items to industry expectations. I'm hoping to find some information on what percentage of a dev's salary is generally spent on tooling, both hardware and software. Where can I find such information?
If instead there is a source that looks at raw…
I have created a Linux kernel and for some reason an extra drive is always added at bootup.
My hard drive is listed as /dev/sdb. /dev/sda is created too, and it is 8 MB in size. I can't find anything in the kernel config that is creating this, but if I use a different kernel it is not there. Kernel…
One of my server's drives failed and so I removed the failed drive from all three relevant arrays, had the drive swapped out, and then added the new drive to the arrays. Two of the arrays worked perfectly. The third added the drive back as a spare, and there's an odd "removed" entry in the mdadm…
I just upgraded Ubuntu 14.04, and I had two ZFS pools on the server. There was some minor issue with me fighting with the ZFS driver and the kernel version, but that's worked out now. One pool came online, and mounted fine. The other didn't. The main difference between the tool is one was just a…

I have a volume group consisting of 5 RAID1 devices grouped together into a lvm and formatted with xfs. The 5th RAID device lost its RAID config (cat /proc/mdstat does not show anything). The two drives are still present (sdj and sdk), but they have no partitions. The LVM appeared to…
After my lastest update for Ubuntu and Windows XP, I got a Grub error on booting the next day. ls lists the following (without () ):

Okay, this is starting to get pretty frustrating. I've read most of the other answers on this site that have anything to do with this issue but I'm still not getting anywhere. I have a RAID 6 array with 10 devices and 1 spare. The OS is on a completely separate device. At boot only three…
Attempting to add a disk to mirror an LVM volume on CentOS 7 always fails with "Insufficient free space: 1 extents needed, but only 0 available". Having searched for a solution, I have tried specifying disks, multiple logging options, adding 3rd log partition, but have not found a…
I'm running the lastest Ubuntu 12.04 AMI (ami-a29943cb) from Canonical on Amazon EC2 and quite often when I log in I get the message:

I have read a bunch of documentation on this and seem to understand that every so…
I have this small bash script which helps use Infinality font rendering options via a more user-friendly Zenity window.
But whenever I launch it I have this "Color Picker" title on Unity Panel together with the icon assigned for "Color Picker" utility.
I wonder why and how…
This is the current state of my partition table. As can be seen, the boot is very small, and I cant upgrade the kernel, because the update-manager tells me there isnt enough space on /boot :( Which effectively means that I cant update my kernel. Can I change the size of my…

I'm facing with a pretty easy problem in my opinion.
I've extracted a working disk from a RAID1 and I'm looking to copy only data (FS and RAID configuration doesn't matter) into another location (another FS).
My problem is I'm not able to mount properly this disk…
