comment How to properly use the the MegaCli command for a LSI Megaraid Secure erase for an SSD?
+1. The MegaCLI help is pretty awful. As an alternative, LSI now publish a tool called StorCli, which replaces MegaCLI. Might be worth looking at.

comment Signal Root to Execute a Program
If you do this, also make very sure that the new user doesn't have write permission to /scripts/myscript or /scripts/. If they have write permission, they can modify the script to run arbitrary code, which defeats the point of locking things down this way.

comment Batch rename files that end in a dot
@CristianCiupitu: That might be it. I pulled my example from the link I referred to on askubuntu.com, and I tested on ubuntu. Looks like dash is sufficiently similar to bash in this case, but it might not be on other systems

Nice, I didn't know about rename. Much simpler.

comment Diagnosing disk health with smartctl
I'd like to clarify your point about early warning: If SMART (error log/attribute/overall health check) give you evidence to suggest the drive is not healthy, you can be very sure the drive is not healthy and you should replace it. But the absence of these indicators doesn't mean the drive won't have issues in the near future. SMART is a perfectly good indicator of a failing drive, it's just not a good indicator of a healthy one.

comment Ubuntu 12.04: apt-get “failed to fetch”; apt is trying to fetch via old static IP
Braiam is on the right track, but you may need to look in other files in /etc/apt to see where you set the proxy. I suggest grep 8118 -r /etc/apt as a wider search.

comment Ubuntu 12.04: apt-get “failed to fetch”; apt is trying to fetch via old static IP
That option might be set in /etc/apt/apt.conf directly (eg, the file, not the include directory). I'd try 'grep 8118 -r /etc/apt/' as a wider search

comment MacBooks are destroying SSDs
SMART on SSDs doesn't show the same parameters as a spinning drive, because the ones it doesn't show aren't relevant to an SSD (head fly height, for example, is meaningless when you don't have heads). However, your SMART app doesn't have the latest drivedb, which is why you get all those 'Unknown Attributes'. They will be useful to you, if you can work out what they are. I don't know what app you're using, so I can't comment on how to update them, but if you install the latest version of smartmontools it should be fine.

comment Filesystems for webserver with SATA and Solid State disk,
SSDs do have a limited number of write cycles, however this is very predictable and can be monitored over time. Also, if you're careful about SSD selection (and you don't need to speed thousands of dollars these days), you can get SSDS that won't practically wearout.

comment Filesystems for webserver with SATA and Solid State disk,
Any modern (Sep 2013, but for a good year or so prior to now at least) SSD will massively outperform a SATA drive for both sequential and random throughput. Current consumer grade cheap SSDs can sustain 400MB/sec sequential access easily, whereas the best 7200RPM SATA drive will peak at around 180MB/sec on the outer edge of the drive and around half that on the inner edge.
