Your DNS Server Is Helping DDoS Attacks [30984]
Information Week, May 5th, 2013
"In the first quarter of this year, it was reported that the Internet experienced a 700 percent DDoS bandwidth increase. As DDoS attacks force more bandwidth onto a target, it means that even the largest enterprise networks can succumb to over-utilization.
DDoS attacks are growing increasingly sophisticated and take advantage of dozens, hundreds, or even thousands of compromised machines that form enormous botnets. But more importantly, they increasingly make use of non-compromised, but misconfigured, public DNS servers. Your enterprise might be responsible for these servers..."

So You Want To Be A Unix Sysadmin? [30606]
ITWorld, April 8th, 2013
"After several decades of administering Unix systems, I know more than I'd like to admit about 'the good, the bad, and the challenging' of Unix systems administration. I've worked in companies with as few as four employees and others with tens of thousands.
I've spent weeks doing routine, repetitive work and weeks grappling with such incredibly complex assignments that I've wondered if my brain was about to explode. I've had years in which I actually looked forward to Monday mornings and those in which I just couldn't wait for Fridays..."

An old IT ninja learns new Unix tricks - vim [30233]
InfoWorld March 11th, 2013
"It was with some fascination that I happened across Ian Langworth's "VIM after 11 years" post last week. As a vi/vim user for more than 20 years, I wasn't expecting to learn much. But to my surprise, Langworth revealed many features and tweaks I never would've sought out on my own because -- well, why would I? My vim reflexes have been built up like calluses over decades, long before many of these features and plug-ins were a glimmer in anyone's eye.
Yet I found some very old features that I either never knew about or used so sparingly that they've been archived..."

The Benefits of Hardware Neutral, Server-side Caching [30143]
Storage Switzerland, March 7th, 2013
"Caching has been around as long as computers have. Theres a cache in the CPU, at the OS, in applications like databases, even disk drives have a small cache area. Basically any device which handles an I/O operation typically uses a cache to buffer an I/O data stream. However, caching in a storage context is a little different and caching with flash as a faster storage area for improving application performance is newer still.
Storage caching has become more popular lately because of the availability of NAND flash devices. .."

How to Stress-Test Your PC Hardware [30144]
PCWorld, February 22th, 2013
"Modern-day PCs are more reliable than ever before, but that doesnt mean they're infallible. Equipment failures still happen, however rarely, and even the beefiest of computer components aren't worth their weight in silicon if they aren't dependable. Thankfully, the hot and heavy world of stress testing can help to identify critical faults before your PC craps out in the middle of a critical operation.
Whenever you buy or build a PC, swap out a major component, or overclock a piece of hardware, it's a good idea to stress-test (or "burn in") the fresh gear, which is not the same as benchmarking your rig..."
