Modern Microprocessors - A 90-Minute Guide! WARNING: This article is meant to be informal and fun! Okay, so you're a CS graduate and you did a hardware course as part of your degree, but perhaps that was a few years ago now and you haven't really kept up with the details of processor designs since then. In particular, you might not be aware of some key topics that developed rapidly in recent times... pipelining (superscalar, OOO, VLIW, branch prediction, predication) multi-core and simultaneous multi-threading (SMT, hyper-threading) SIMD vector instructions (MMX/SSE/AVX, AltiVec, NEON) caches and the memory hierarchy Fear not!
But be prepared – this article is brief and to-the-point. More Than Just Megahertz The first issue that must be cleared up is the difference between clock speed and a processor's performance. Table 1 – Processor performance circa 1997. A 200 MHz MIPS R10000, a 300 MHz UltraSPARC and a 400 MHz Alpha 21164 were all about the same speed at running most programs, yet they differed by a factor of two in clock speed. RackTables.

DEVONthink — Smart document management for Mac. Beware of soapy frogs: Using IET (ISCSI Enterprise Target) for Windows Server Backup. Windows Server Backup in win2k8 server is fantastic - it's a consistent, snapshot-based automatic backup system capable of full disaster recovery / bare metal restore. I'm not a huge fan of much of the way the Windows servers work, but the backup setup is fantastic. With one wee flaw... Manual backups may be made to a network share, or to a local volume then copied to a network share. Fuss free, but only with operator intervention.
Unfortunately, automatic scheduled backups require direct access to a drive, they won't work on a mounted NTFS volume or on a network share. This doesn't do me much good for disaster recovery, as even a USB2 or FireWire drive nearby has a good chance of being destroyed by anything that takes out my server. It rained (and hailed) in my server room last month, so I'm taking disaster recovery even more seriously, and a nearby HDD just isn't good enough.
The solution: Win2k8 has a built-in iSCSI initiator. Security notice Configuring the iSCSI target. T E X T F I L E S D O T C O M. Plan 9 from Bell Labs.

NIST uses three NIST Special Publication subseries to publish computer/cyber/information security and guidelines, recommendations and reference materials: SP 800, Computer Security (December 1990-present): NIST's primary mode of publishing computer/cyber/information security guidelines, recommendations and reference materials (SP 800s are also searchable in the NIST Library Catalog); SP 1800, NIST Cybersecurity Practice Guides (2015-present): A new subseries created to complement the SP 800s; targets specific cybersecurity challenges in the public and private sectors; practical, user-friendly guides to facilitate adoption of standards-based approaches to cybersecurity; SP 500, Computer Systems Technology (January 1977-present): A general IT subseries used more broadly by NIST's Information Technology Laboratory (ITL), this page lists selected SP 500s related to NIST's computer security efforts.
