image1460411941.jpgWhen installing stuff in an HP rack or another rack that uses those pop-in pem nuts in the square rack holes, don’t waste time and beat up your hands trying to pinch the pem nut tabs into the holes. That little flat piece of metal they put in the bag is a mini crowbar. Just put the bottom tab of the pem nut in the hole, catch the top with the lip of the crowbar thing, and lever it in. Fast, easy, and saves your fingers.

I was recently faced with having to make a copy of a bunch of data — nearly a terabyte — to backup a server before a major software upgrade on it. A test run of the copy looked like it’d take about 24 hours for the data to copy using “cp -Rp”. I wasn’t happy with that and wanted to cut it down, so I tried making a compressed tarball of the data instead, using “tar czvf”. Guess what? Creating the tarball took about half the time, just over 12 hours. If you think about it, this makes sense… you can’t change the amount of data you read in during a copy, but you can change the amount you write out through compression. By trading disk I/O for CPU, I was able to nearly cut the copy time in half. This also works for restoring the data too, just remember that you’re trading disk I/O for CPU. :)
