The two Books of Chronicles (Hebrew: דברי הימים Diḇrê Hayyāmîm, "The Matters of the Days"; Greek: Παραλειπομένων, Paraleipoménōn) are the final books of the Hebrew Bible in the order followed by modern Judaism; in that generally followed in Christianity, they follow the two Books of Kings and precede Ezra–Nehemiah, thus concluding the history-oriented books of the Old Testament. In the Christian Bible, the books are commonly referred to as 1 Chronicles and 2 Chronicles, or First Chronicles and Second Chronicles.
The English title comes from the 5th century scholar Jerome, who referred to the book as a chronikon; in Hebrew it is called Divrei Hayyamim "The Matters [of] the Days", and in Greek, Paralipoménōn (Παραλειπομένων), "things left on one side".
Chronicles begins at the beginning of the history of humanity, with Adam, and the story is then carried forward, almost entirely by genealogical lists, down to the founding of the Israelite monarchy (1 Chronicles 1–9). The bulk of the remainder of 1 Chronicles, after a brief account of Saul, is concerned with the reign of David (1 Chronicles 11–29). The next long section concerns David's son Solomon (2 Chronicles 1–9), and the final part is concerned with the kingdom of Judah with occasional references to the kingdom of Israel (2 Chronicles 10–36). In the last chapter Judah is destroyed and the people taken into exile in Babylon, and in the final verses the Persian king Cyrus conquers Babylon, and authorises the restoration of the Temple in Jerusalem, and the return of the exiles.
A 3char is a domain name or AOL Instant Messenger (AIM) screen name with only three characters.
Since AIM screen name must start with a letter, there are only 33,696 valid three-character screen names (), and 46,656 valid three-character second-level domain names per top-level domain (
).
Since all of these screen names were registered in the middle 1990s, mostly by America Online members, these are a form of online "rarity", sought after by youths, hackers, or anyone wanting their screen name to appear impressive. 3chars are regularly sold or traded online. Many people have cracked the password of 3char accounts through brute-force search or using AOL Exploits and hacks to obtain the accounts.
Additionally, complex methods of screen name theft have been developed over time to allow AOL crackers to gain unauthorized access to rare screen names, including 3chars. In late 2000, one AOL cracker reportedly developed software which used an AOL security glitch to gain access to all three-character screen names vulnerable to that security issue, effectively bringing many thousands of these screen names under his control. This resulted in numerous long-time users losing their accounts, and began a cottage industry of screen name barter and sale.
85 Ceti is an older Flamsteed designation for a star that is now within the borders of the northern constellation of Aries, the ram. In the present day it is known by star catalogue designations such as HD 16861 and HR 797. It has an apparent visual magnitude of 6.30 and is approximately 410 light-years (130 parsecs) distant from the Earth. This is an A-type main sequence star with a stellar classification of A2 V. It has 2.4 times the mass of the Sun and shines with 48 times the Sun's luminosity. This energy is being radiated into outer space from the star's outer atmosphere at an effective temperature of 8,810 K. This heat gives it the white-hued glow of an A-type star.
In computing, a data segment (often denoted .data) is a portion of an object file or the corresponding virtual address space of a program that contains initialized static variables, that is, global variables and static local variables. The size of this segment is determined by the size of the values in the program's source code, and does not change at run time.
The data segment is read-write, since the values of variables can be altered at run time. This is in contrast to the read-only data segment (rodata segment or .rodata), which contains static constants rather than variables; it also contrasts to the code segment, also known as the text segment, which is read-only on many architectures. Uninitialized data, both variables and constants, is instead in the BSS segment.
Historically, to be able to support memory address spaces larger than the native size of the internal address register would allow, early CPUs implemented a system of segmentation whereby they would store a small set of indexes to use as offsets to certain areas. The Intel 8086 family of CPUs provided four segments: the code segment, the data segment, the stack segment and the extra segment. Each segment was placed at a specific location in memory by the software being executed and all instructions that operated on the data within those segments were performed relative to the start of that segment. This allowed a 16-bit address register, which would normally provide 64KiB (65536 bytes) of memory space, to access a 1MiB (1048576 bytes) address space.
DATA were an electronic music band created in the late 1970s by Georg Kajanus, creator of such bands as Eclection, Sailor and Noir (with Tim Dry of the robotic/music duo Tik and Tok). After the break-up of Sailor in the late 1970s, Kajanus decided to experiment with electronic music and formed DATA, together with vocalists Francesca ("Frankie") and Phillipa ("Phil") Boulter, daughters of British singer John Boulter.
The classically orientated title track of DATA’s first album, Opera Electronica, was used as the theme music to the short film, Towers of Babel (1981), which was directed by Jonathan Lewis and starred Anna Quayle and Ken Campbell. Towers of Babel was nominated for a BAFTA award in 1982 and won the Silver Hugo Award for Best Short Film at the Chicago International Film Festival of the same year.
DATA released two more albums, the experimental 2-Time (1983) and the Country & Western-inspired electronica album Elegant Machinery (1985). The title of the last album was the inspiration for the name of Swedish pop synth group, elegant MACHINERY, formerly known as Pole Position.
The word data has generated considerable controversy on if it is a singular, uncountable noun, or should be treated as the plural of the now-rarely-used datum.
In one sense, data is the plural form of datum. Datum actually can also be a count noun with the plural datums (see usage in datum article) that can be used with cardinal numbers (e.g. "80 datums"); data (originally a Latin plural) is not used like a normal count noun with cardinal numbers and can be plural with such plural determiners as these and many or as a singular abstract mass noun with a verb in the singular form. Even when a very small quantity of data is referenced (one number, for example) the phrase piece of data is often used, as opposed to datum. The debate over appropriate usage continues, but "data" as a singular form is far more common.
In English, the word datum is still used in the general sense of "an item given". In cartography, geography, nuclear magnetic resonance and technical drawing it is often used to refer to a single specific reference datum from which distances to all other data are measured. Any measurement or result is a datum, though data point is now far more common.
Selcall (selective calling) is a type of squelch protocol used in radio communications systems, in which transmissions include a brief burst of sequential audio tones. Receivers that are set to respond to the transmitted tone sequence will open their squelch, while others will remain muted.
Selcall is a radio signalling protocol mainly in use in Europe, Asia, Australia and New Zealand, and continues to be incorporated in radio equipment marketed in those areas.
The transmission of a selcall code involves the generation and sequencing of a series of predefined, audible tones. Both the tone frequencies, and sometimes the tone periods, must be known in advance by both the transmitter and the receiver. Each predefined tone represents a single digit. A series of tones therefore represents a series of digits that represents a number. The number encoded in a selcall burst is used to address one or more receivers. If the receiver is programmed to recognise a certain number, then it will un-mute its speaker so that the transmission can be heard; an unrecognised number is ignored and therefore the receiver remains muted.
