Canon’s site for the LiDE 50 does not list any Windows 7 drivers for download, nor Vista 64-bit drivers. However, I did find that you can use the CanoScan LiDE 60 drivers in place of the LiDE 50 drivers, and they do have options listed for Windows 7/Vista in both 64-bit and 32-bit varieties. Do do this, you download the appropriate driver (either the Windows 7 64 or 32 drivers) which is contained in an executable file. Use a program such as 7zip to uncompress this file into another folder. Within this folder, there are no drivers but further cabinet files. Use 7zip to decompress the _winzip_ file, which actually contains the driver you need to install. In your device manager, locate the scanner and select the option to update the driver. You will need to select the driver manually, then specify the device type and driver, then click the “Have….

EDID stands for Extended display identification data and is what many computer monitors and televisions with a VGA/HDMI use to tell the PC what resolution they support. Which, in theory at least, is great. However what I recently found out is that many LCD and Plasma televisions do not broadcast the correct 16:9 resolution via EDID, and therefore the computer doesn’t know what resolution to display and you have a stretched image.

We recently did some speed testing on a few of the servers on our network, and we were not receiving the speeds expected considering they were sitting on a physical 100mbps ethernet port. The servers were indeed on physical 100mbps connection, however wget (TCP/IP, HTTP Port 80) download tests showed only a max of about 1.5MB/sec (note the 8bit/byte conversion, so this translates to about 12mbits).

I put this together for a project in a class I am taking, and thought it would be handy for others as well. The goal is to access a Windows filesystem and reset the password for a user, for example if someone forgot the Administrator password or the account is locked out from too many bad password login attempts. This works on all modern Windows Operating Systems: Windows 2000, 2003, XP, Vista, Win7 etc. Make sure to create a backup if you want to make sure you don’t corrupt your Windows install, as it can happen. Tools used: Unetbootin Ubuntu 9.10 Desktop ISO One flash drive, 1 gig or larger chntpw Accessing the Filesystem First we use unetbootin to install Ubuntu 9.10 to a flash drive. The flash drive needs to be at least 1GB to install the image. Select “Diskimage” and then the .iso file we downloaded of the….

Did you ever have a situation where you needed to access a website that had an IP restriction in place? I recently had a situation where I needed to access the web via my university connection (due to IP restrictions placed on accessing databases of research papers). They do not have a VPN setup so it is hard to do this off-campus. I do however have access to a linux machine on campus. I am familiar with port forwarding using SSH but I had never used it to actually tunnel web traffic using a web browser on Windows. Turns out it is surprisingly easy! The ssh command to use is: 1ssh -C2qTnN -D 8080 username@remote_host This command sshes to the remote_host, and creates a tunnel on your localhost, port 8080. Note that you need to have private key authentication already set up for this host – it will not work….

I was recently tasked with copying speaker’s presentations, files and handouts onto 100s of USB Drives (key drives) for a conference that work is hosting down in Washington, D.C. My first thought was that it was going to be a pain to have to copy/paste the files to each drive. I thought about creating a batch script to copy the files with a double click. But really, who wants to be doing all of that clicking and/or typing? Work smarter, not harder. Then I remembered a neat feature that SyncBackSE, a program I use at home for backups, has available. The backup program – which is basically a file copy process – can be triggered based on the insert of a drive, whether that be a USB Key Drive or an External Hard Drive. Using the program, the only action you need to do to trigger the copy process is….

You’ve flashed your old WRT54G or other vanilla router with the Tomato firmware. This itself turns your router into a lean, mean routing machine with QOS, SSH and more, but let’s say we want to take it a bit further. What it we want to get some more stats out of it? In order to do this, we first need to set up a way to pull this information from the router. The best way to do this is to install an SNMP (Simple Network Management Protocol) daemon on the system. The main roadblock we face here is that the system mainly runs in volatile system memory, meaning that every time the system is rebooted the filesystem is reset. Fortunately Tomato provides a way to get around this using CIFS shares. Follow the steps below (as modified from here) to install an SNMP server on a Tomato router. Create a….
