How do I find a dual DVI-D (dual link) graphics card for 2560x1440 resolution?

I have a Dell Optiplex 3010 computer which has 1 x VGA and 1 x HDMI (they are only capable of displaying 1920 x 1050 resolution). I've opted to shop for a new graphics card, but it wasn't easy to choose one as descriptions of the products shown on major websites weren't clear enough to ensure compatibility.

How to edit Windows hosts file (C:\Windows\System32\Drivers\Etc\hosts)?


Windows users have a trouble saving plain TXT files without extensions on a Windows machine. For example, if you have to edit C:\Windows\System32\Drivers\Etc\hosts file and save as a plain text file, Windows will automatically add .txt file extension to the file and save it as hosts.txt. Also, Windows does not allow you to edit the file directly in the system folder such as the C:\Windows\System32\Drivers\Etc.

How to share a folder between the VMware host and guest?


If you need to share a holder between your Windows host and Linux guest, you may use native VMware folder sharing available on VMware Workstation or VMware Player.

My serial printer doesn't work. What shall I do?


Serial printers generally do not require a device driver to work in a desired software application. If POS software cannot print directly to the serial printer, it is preferable to make sure we can print from the running operating system such as Windows or Linux. Here are a few things to do to diagnose serial printer problem.

Copy and Paste Word document to HTML form


Many users without computer knowledge copy contents from a word document, and paste them into a HTML form (<textarea></textarea>) and expect to retain formating as well as special characters such as smart quotes and emdashes. You may opt to translate smart quotes to regular quotes and emdashes to regular dashes with a PHP script. If any user submits a non-ASCII character contents, you'll probably see weird characters in the database and HTML page. Finding and fixing just a few of them (curly quotes and em dashes) isn't going to solve the real problem.
