Selecting The Right Type Of Hard Drive For Your Needs

  When selecting the right type of hard drive for your needs, beyond speed, capacity, reliability, and any manufacturer preference, you should consider how you will use the drive itself.  For example:  Do you need a drive that will be installed in a desktop computer where the drive will be “on” most of the day,… Continue reading Selecting The Right Type Of Hard Drive For Your Needs

Run speedtest.net From the Command Line With speedtest-cli

For years, my “goto” source for measuring internet speed has been speedtest.net. Pointing my browser to speedtest.net, and a with few mouse clicks, I got my internet speeds for the moment. The absence of “flash” has made the GUI of speedtest.net even more usable, and it seems faster. Recently, the good people at Speedtest have… Continue reading Run speedtest.net From the Command Line With speedtest-cli

UFW: The Linux Uncomplicated Firewall

Shhh! LarryTalksTech has a new baby sister.

Recently while monitoring traffic on my LAN, I noticed activity from URL’s and IP addresses that had somehow got past my router, and were roaming my network.  Some immediate tweaks to my router stopped that activity (at least for the time being). The event forced me to rethink security for my networked computers, and one… Continue reading UFW: The Linux Uncomplicated Firewall

Using the Linux “Whatis” and “Man” Commands

Saying the Linux and Unix shell commands are not intuitive is an understatement of epic proportions.  It might be easier to learn Klingon.  There is help for finding out about the Linux and Unix commands however, and it is found in the unassuming commands, whatis and man.  The syntax for whatis couldn’t be simpler:  whatis… Continue reading Using the Linux “Whatis” and “Man” Commands
