Livescribe
The Livescribe paper-based computing platform consists of a digital pen, digital paper, software applications, and developer tools. Central to the Livescribe platform is the smartpen, a ballpoint pen with an embedded computer and digital audio recorder. When used with Anoto digital paper, it records what it writes for later uploading to a computer, and synchronizes those notes with any audio it has recorded. This allows users to replay portions of a recording by tapping on the notes they were taking at the time the recording was made. It is also possible to select which portion of a recording to replay by clicking on the relevant portion of a page on-screen, once it has been synced to the Livescribe Desktop software. Jim Marggraff, inventor of the LeapFrog FLY Pentop computer and creator of the LeapPad Learning System, left Leapfrog in 2005 to form Livescribe. In November 2015, Livescribe announced its acquisition by Anoto for $15m.

BLAST
In bioinformatics, BLAST (basic local alignment search tool) is an algorithm for comparing primary biological sequence information, such as the amino-acid sequences of proteins or the nucleotides of DNA and/or RNA sequences. A BLAST search enables a researcher to compare a query sequence with a library or database of sequences, and identify library sequences that resemble the query sequence above a certain threshold. Different types of BLASTs are available according to the query sequences. For example, following the discovery of a previously unknown gene in the mouse, a scientist will typically perform a BLAST search of the human genome to see if humans carry a similar gene; BLAST will identify sequences in the human genome that resemble the mouse gene based on similarity of sequence. The BLAST algorithm and program were designed by Stephen Altschul, Warren Gish, Webb Miller, Eugene Myers, and David J. Lipman at the National Institutes of Health and was published in the Journal of Molecular Biology in 1990 and cited over 50,000 times.

Right Triangle
A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry. The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (or catheti, singular: cathetus). Side a may be identified as the side adjacent to angle B and opposed to (or opposite) angle A, while side b is the side adjacent to angle A and opposed to angle B. If the lengths of all three sides of a right triangle are integers, the triangle is said to be a Pythagorean triangle and its side lengths are collectively known as a Pythagorean triple.

Bit Manipulation Instruction Set
Bit manipulation instructions sets (BMI sets) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD. The purpose of these instruction sets is to improve the speed of bit manipulation. All the instructions in these sets are non-SIMD and operate only on general-purpose registers. There are two sets published by Intel: BMI (here referred to as BMI1) and BMI2; they were both introduced with the Haswell microarchitecture. Another two sets were published by AMD: ABM (Advanced Bit Manipulation, which is also a subset of SSE4a implemented by Intel as part of SSE4.2 and BMI1), and TBM (Trailing Bit Manipulation, an extension introduced with Piledriver-based processors as an extension to BMI1, but dropped again in Zen-based processors).

List of Mergers and Acquisitions by IBM
IBM has undergone a large number of mergers and acquisitions during a corporate history lasting over a century; the company has also produced a number of spinoffs during that time. The acquisition date listed is the date of the agreement between IBM and the subject of the acquisition. The value of each acquisition is listed in USD because IBM is based in the United States . If the value of an acquisition is not listed, then it is undisclosed. Many of the companies listed in this article had subsidiaries of their own who had subsidiaries who ... For examples, see Pugh's book Building IBM, page 26.
