Topic: Root computing

	List of Abstracts Submitted for ROOT 2001
		ROOT, a physics analysis package developed at CERN, is used in the D-Zero online monitoring as the main analysis tool, providing a graphical user interface that interacts remotely with an analysis executable and tools to monitor informative histograms as they get updated throughout the data taking.
		ROOT is used as the main analysis tool for the monitoring of the performance of each subsystem and its GUI is used to browse the results via socket.
		GRID technology for distributed computing is considered a promising solution for the challenging computing problem of the CERN LHC experiments where petabytes of data recorded every year have to be asinchronously accessed and processed by thousands of peoples geographically distributed all over the planet.

	nedmartin - UNI - COMP3502 - Assignment 1 - Trusted Computing
		The term TC, for trustworthy computing, forms a more apt generalisation of the field, and is the term I shall be using to refer to trustworthy and trusted computing in general.
		The physical aspect of TCG begins with a Trusted Platform Module, or TPM[9], which is typically a hardware device physically attached to a computer in such a manner that it is infeasible to transfer it intact to another computer.
		Using a typical personal computer as an example[14], when first powered on, the TCM starts and the RTM, which is implicitly trusted, verifies the computer’s basic operating system loading code by storing a digest of the code in the update-only RTS, which in turn verifies the operating system itself, which can then verify an application.

	Computing Apportionment
		The multiplier equals (1 divided by (the square root of n(n-1)) [which is called the reciprocal of the geometric mean].
		Computing these values is quite easy using a PC and a good spreadsheet package.
		Once the "multipliers" have been calculated, the next step is to multiply this figure by the population total for each of the 50 states (the District of Columbia is not included in these calculations).

	Embedded.com - Improve your root-mean calculations
		One common method for computing the square root is Newton's method, which iteratively converges on a solution using an initial estimate.
		The root-mean is computed as the square root of the average over time of its input.
		In this case, the average is computed as the weighted sum of the current input and the previous output.

	Attackers Target Internet Root Servers - Computing News - Digital Trends
		Three of the thirteen top-level root servers—one operated by ICANN, one by the U.S. Department of Defense, and one by UltraDNS—were briefly overwhelmed with the flood of bogus traffic pointed at them from hordes of so-called "zombie" computers around the world, although none of the three ever stopped working entirely.
		"These zombie computers could have brought the web to its knees, and while the resilience of the root servers should be commended, more needs to be done to tackle the root of the problem—the lax attitude of some users towards IT security," said Graham Cluley, senior technology consultant at Sophos, in a statement.
		Denial-of-service attacks are typically used by cyber-criminals as an extortion mechanism: they take control of a zombie network and use it to flood a key router, server, or single point of failure for a network provider or business such that the organization's Internet connectivity grinds to a halt or the server's crash under the load.

		The parameters f1 and f1prime would refer to the particular C functions that implement the math function whose root is to be determined.

	Good Math, Bad Math : Computing Square Roots on Paper
		To do a square root on an abacus, you use partitions to do a paper algorithm for square root using the abacus.
		I was curious about how to do roots by hand a while back and found another algorithm, which was basically take a few guesses and average them out and see what you get.
		What I was taught is basically Newton's method as applied to square roots: to find the square root of t, make a guess x and repeatedly take the average of t/x and x as the new value of x.

	Linux vs. Windows Viruses \| The Register
		And since Linux users are taught from the get-go to never run as root, and since Mac OS X doesn't even allow users to use the root account unless they first enable the option, it's obvious the likelihood of email-driven viruses and worms lessens on those platforms.
		The growth of the Microsoft monoculture in computing is a dangerous thing for users of Microsoft products, but also for all computing users, who suffer the consequences of disasters in that environment, such as wasted network resources, dangers to national security, and lost productivity (note: the link is to a 880 kb PDF file).
		By default, Lindows runs the user of the system as root (and it even encourages the user to forgo setting up a root password during installation by labeling it as "optional"!), an unbelievably shortsighted decision that results in a Linux box with the same security as a Windows 9.x machine.
