NewsForge | Linux to the rescue: A review of three system rescue CDs: "System Rescue CD is the largest download at 110MB. It includes:
Linux-kernel-2.4.27-xfs
GNU-Parted-1.6.11 -- This reliable text-based partition editor is the best Linux partition tool.
QtParted and PartGui are regarded as the best free PartitionMagic clones for Linux, and you can use these two graphical partition tools without XFree86. They work with QtEmbedded and allow you to see a chart of your hard disk, create, format, delete, and modify partitions.
Partimage-0.6.4 is a Ghost/DriveImage clone for Linux.
GRUB-0.94 / LILO-22.5 -- These tools are the most common bootloaders used with Linux. You can restore your bootloader from this System Rescue CD. For example, if Windows removed GRUB, you can run GRUB from this CD and reinstall the bootloader.
File system tools
Evms 2.3 is a powerful logical volume manager.
Archiving tools tar/gzip/bzip2 are provided for Unix users. Zip/unzip, while rar/unrar/unace are provided for Windows users. "

Why Smart People Have Bad Ideas
Why Smart People Have Bad Ideas: "If you want to learn what people want, read Dale Carnegie's How to Win Friends and Influence People. [8] When a friend recommended this book, I couldn't believe he was serious. But he insisted it was good, so I read it, and he was right. It deals with the most difficult problem in human experience: how to see things from other people's point of view, instead of thinking only of yourself.
Most smart people don't do that very well. But adding this ability to raw brainpower is like adding tin to copper. The result is bronze, which is so much harder that it seems a different metal."

Cooking with Lisp
Cooking with Lisp: "Robert W. Floyd's 1978 Turing Award Lecture, hosted by Markus Fix here, and he has a great quote about Lisp:
I have seen numerous examples of the programming power which Lisp programmers obtain from having a single data structure, which is also used as a uniform syntactic structure for all the functions and operations which appear in programs, with the capability to manipulate programs as data. Although my own previous enthusiasm has been for syntactically rich languages like the Algol family, I now see clearly and concretely the force of Minsky's 1970 Turing lecture, in which he argued that Lisp's uniformity of structure and power of self reference gave the programmer capabilities whose content was well worth the sacrifice of visual form.

Supported System Configurations
Supported System Configurations: "J2SE 5.0 does not provide support for Itanium 2 -- Itanium 2 support may be added in subsequent update releases"
Myrinet Overview
Myrinet Overview: "Messages can be sent and received without system calls, resulting in measured message latencies at the MPI level with the 'E card' and 'F card' NICs of ~2.7�s with MX, and ~6.5�s with GM. Message latencies using the popular, low-cost, 'D card' NICs are ~0.8�s higher. Thanks to the OS-pass mode of operation and to protocol processing being offloaded to the firmware, the host-CPU overhead is minimal, ~0.15�s per message for sending or receiving.
For either GM or MX, and with single-port NICs, measured, user-level, one-way, data rates are ~1.98 Gb/s (248 MBytes/s), and two-way (summed bidirectional) data rates are ~3.92 Gb/s (490 MBytes/s). With the high-end, dual-port NICs, the firmware takes care of distributing and reassembling packet data across the two ports. The measured, user-level, one-way data rate of ~3.9 Gb/s (~490 GBytes/s) approaches the capacity of the two links. On hosts with good PCI-X throughput, the two-way (summed bidirectional) data rate approaches 6.4 Gb/s (800 MBytes/s)."

Peeking Into Google
Peeking Into Google: "Google replicates the Web pages it caches by splitting them up into pieces it calls 'shards.' The shards are small enough that several can fit on one machine. And they're replicated on several machines, so that if one breaks, another can serve up the information. The master index is also split up among several servers, and that set also is replicated several times. The engineers call these 'chunk servers.'
As a search query comes into the system, it hits a Web server, then is split into chunks of service. One set of index servers contains the index; one set of machines contains one full index. To actually answer a query, Google has to use one complete set of servers. Since that set is replicated as a fail-safe, it also increases throughput, because if one set is busy, a new query can be routed to the next set, which drives down search time per box. "
