One of my readers had a mysterious problem: the WordPress Editor was not showing up under Appearance or Plugins. It’s a handy tool for quick edits to any plugin or theme file, and I’ve relied on it more times than I can count. Having it enabled is a double-edged sword of course, because with great … Read more
Hidden files start with a . on UNIX like systems and OS X is one of them. While we can show hidden files in a Ternimal session by using something like ls -a, it’s not so easy to convince the Finder to show such files. If ever you need to see them, execute the following … Read more
Parallels have announced this week that they’ve changed their name to brand cloud services from Parallels to Odin. This blog post has more details: http://blog.odin.com/serviceprovider/2015/3/24/weve-changed-our-name-parallels-service-provider-business-is-now-odin#.VRVXAVz-_68= While I dislike change for the sake of change, I believe that it makes a lot of sense in this case. I have been working with Parallels products since 2008, … Read more
There are two ways I know of which will print the UUID of all disk drives attached to the current system: blkid /dev/sr0: UUID=”2014-12-02-19-30-23-00″ LABEL=”CDROM” TYPE=”iso9660″ /dev/sda1: UUID=”ae55a647-3c57-4ab5-9651-1389703fe6fe” TYPE=”ext4″ /dev/sda2: UUID=”bMtCfO-zpDU-7U1t-DcHg-Fe9p-Cy1K-Se0e1I” TYPE=”LVM2_member” /dev/sdb1: UUID=”0982ce66-537a-497b-baaf-99136594f3e8″ TYPE=”ext4″ /dev/mapper/VolGroup-lv_swap: UUID=”8f0652a8-d79b-453f-aa2d-0ff0b5d0ae7b” TYPE=”swap” /dev/mapper/VolGroup-lv_root: UUID=”5afc1b25-e6cd-45b2-ad20-69f0fed323b9″ TYPE=”ext4″ /dev/mapper/VolGroup-lv_home: UUID=”94e15e98-1cff-49a9-b76a-a8f3a948e2ea” TYPE=”ext4″ or ls -la /dev/disk/by-uuid total 0 drwxr-xr-x. 2 root root 160 … Read more
I passionately *H*A*T*E* the startup chime that my Mac makes when I switch it on. At least on my MacBook, if the volume is turned down before I shutdown, the system restarts silently. I guess it’s somehow linked to the internal speakers. Sadly on my Mac Mini this approach doesn’t work: due to the lack … Read more
There’s a built-in command line tool in every Mac called caffeinate that prevents your computer from going to sleep, even when the lid is closed. This is the default behaviour if an external monitor is attached, but if that’s not the case, MacBooks just go to sleep as soon as you close the lid. While … Read more
It’s never good if your server is working fine, but the domains that resolve to it are down for one reason or another. This has happened to me TWICE this year already, and both times it was out of my hands (yes @ENOM, I’m looking at you). Many of my clients use websites for data storage, … Read more
It’s easy to establish an FTP connection using the ftp command from the Linux Command Line. Sadly this command does not accept login credentials as parameters – which means that if we use it in a script, our script will pause and wait for us to type those credentials in manually. Not really suitable for … Read more
