comment How do I detect SD card insertion (just the SD card, not the card reader) in Linux?
@WoJ: 3.2.0-27; I currently don't have a SD card to try this and post the exact message.

comment How do I detect SD card insertion (just the SD card, not the card reader) in Linux?
Hmmm...the card insertion event generates a "detected capacity change from 0 to 123456789" line in syslog for me (where 123456789 is card capacity in bytes, IIRC); not sure what is generating this (logged as "kernel").

comment Weird porn searches showing up in history (NSFW)
@EBGreen: Quite the opposite. Gone are the olden days when people wrote viruses to show off; most malware these days aims for commercial gain - be it ad popups, clickjacking, identity theft, ransom, corporate espionage or something else. Perhaps those searches might have been inserted by malware trying to promote some shady site?

comment How to take the screenshot in windows XP on virtualbox?
Great find, thanks! Looks useful - in addition, this should probably work for any combination of VM host/VM guest.

comment VirtualBox + Windows XP Machines + Bridge Mode
Check the network card settings in Virtualbox - you may want the "bridged" mode on both machines, and set it to bridge on the same card: virtualbox.org/manual/ch06.html

comment How to view the contents of .dat file in linux
That depends on what the file is. .dat is such a generic extension that it could be anything. Where did you get the file from? What type of data do you expect to be contained in the file?

comment Sending files through ssh
"It always returns some kind of error, and so." Be specific - can you, possibly, copy and paste both the invocation, and the error. (If you're on Windows, perhaps try the WinSCP client? It's free and it has a quite useful GUI; I found it much easier to use than the command-line tools available for Windows)

Also, "doesn't work" is the least useful description that you could provide. Be Specific.

comment Turn off drive after “Safely Remove”?
"How does cutting the power at the port differ from unplugging the cable?" - when "cutting the power" through software commands, the 5V power line remains on; whether that affects behavior is undefined in practice (I've seen devices where the software power-down had different effects than physically cutting off power after unmount - as long as the line was on, capacitors remained charged, behavior was based on that).

comment Is it possible to recognise hardware (router or network card) just by its MAC address?
Note that most NICs allow modification of their MAC address. Although this is not too common a practice, it means that you can't positively identify the device just by its MAC address. If you're looking for 90% certainty, the MAC address is good enough.

comment Does Oracle VirtualBox have any power management features?
Note well the difference between acpipowerbutton and poweroff - one sends the "shutdown" ACPI signal, the other yanks the (virtual) power plug.

comment How does one change a PS/2 mouse's polling/refresh/sample rate in 64-bit Windows 7?
Yup - why throw it away if it works? (My brand-new computer still has the venerable PS/2 mouse and keyboard ports; I guess it's cheaper to keep manufacturing them than to design a board without them.) @MBraedley: Low-speed USB devices (as most mice are) introduce input latency which is never less than 8ms, usually more - add in the complexity of the USB stack (compared to the extremely straightforward PS/2 - no hotplugging, no chaining, no power management, has its own line into southbridge) and it adds up to a noticeable delay. (This may not be enough of an issue outside e.g. pro gaming)

comment Which RAID configuration should I go with for fault-tolerance?
"if two drives fail, which is extremely rare" - this is only rare if your disks are uncorrelated. Example: we bought a server with 4 disks, all were from the same batch, one failed after ~1000 hours, another a few hundred hours later. A bad batch, probably (manufacturer replaced them without any opposition at all, I suspect we weren't the only ones affected; the other two are still in service AFAIK).

comment Which RAID configuration should I go with for fault-tolerance?
"raid5 is a bit of a waste on 4 disks" - more than that: on an array this small, it's outright dangerous ( en.wikipedia.org/wiki/RAID_5_write_hole et al) when compared to RAID 10.

comment downsides to running RAID on unmatched drives?
@Scott McClenning: SMART is not very useful in this regard. Of all the drives that have failed me, SMART has actually warned me (and I've been watching the stats pretty closely) in some 10% of the cases - in the remaining 90%, the drives might as well be on fire (heads audibly banging into the enclosure, i/o errors way through the roof, platters trying to spin up and down, smoke pouring out), and SMART would insist they were fine.
