Last week I tried a bunch of different methods to try and upgrade a Dell PE650 BIOS. I finally settled on using a floppy disk to upgrade the BIOS however I initially ran into some issues with various floppy drives and floppy disks. One of the issues was an error message I received when attempting to access the floppy disk located within a floppy drive I had just installed on a Windows XP computer. Below I describe the error and how I was able to get past this specific error.
A couple days ago a CentOS Linux server that I took over administration on had some mysterious files show up in the /tmp and /var/tmp directories. The files were placed in /tmp and /var/tmp by the apache user meaning there is some form of security hole in Apache, PHP, or one of the virtual hosts has an insecure application installed. Before looking into where the issue is I needed to lock things down so no applications could be executed from these directories in the future regardless of a security flaw in the future. Below are instructions on how to secure /tmp and /var/tmp.
Occasionally I get a PC in my shop which has a broken or non working cd drive. One of the mail tools I use is a disk called Hirens Boot CD. Yes I know its considered Warez however it is by far the best collection of tools for a PC tech around so I use it all the time. I will leave finding the actual disc up to you however once you have it you may want to create a USB drive with Hirens for situations when you dont have your cd or the cd option is unavailable.
A friend of mine called the other day and asked if I would stop by to help him setup and configure an external hard drive he had purchased and unsuccessfully setup on his Mac desktop. Upon initial inspection I figured I would just uninstall the WD SmartWare software, reformat the drive, and set it up to simply act as a secondary drive. It turns out that the initial releases of the SmartWare software would require you to configure the drive using SmartWare so I instead of completely wiping the SmartWare software I decided to simply minimize the impact the SmartWare software would have on what my friend wanted to do which was simply have a secondary hard drive that he could copy files to. Below are a couple steps I took to minimize what the WD SmartWare software would do or require you to do before copying files to the external Western Digital hard drive. The first couple of steps are to make sure that the configuration we are starting with is from scratch and sense my friend started the install I wasn’t sure what had been configured so it was better to start over.
I am fairly new to Markdown which is a lightweight markup language. I have really just started becoming more familiar with Markdown while posting or replying to articles in the Question Defense Engage section. Markdown is the markup language used on Engage to format the posted questions, posted responses, comments, and pretty much anywhere that content data is entered. So far I really like Markdown and have been impressed with how user friendly it becomes as you learn the Markdown tricks as I call them including asterisks or underscores for bolding or italicizing, brackets for links/URLs, and numbered lists simply using 1., 2., 3., etc. While the Markdown learning curve has been fairly steep for me the more I use it the more Markdown is sticking with me.
