Code (law)

A code is a type of legislation that purports to exhaustively cover a complete system of laws or a particular area of law as it existed at the time the code was enacted, by a process of codification. Though the process and motivations for codification are similar in different common law and civil law systems, their usage is different. In a civil law country, a Code typically exhaustively covers the complete system of law, such as civil law or criminal law. By contrast, in a common law country with legislative practices in the English tradition, a Code is a less common form of legislation, which differs from usual legislation that, when enacted, modify the existing common law only to the extent of its express or implicit provision, but otherwise leaves the common law intact. By contrast, a code entirely replaces the common law in a particular area, leaving the common law inoperative unless and until the code is repealed. In a third case of slightly different usage, in the United States and other common law countries that have adopted similar legislative practices, a Code is a standing body of statute law on a particular area, which is added to, subtracted from, or otherwise modified by individual legislative enactments.

Hamming space

In statistics and coding theory, a Hamming space is usually the set of all binary strings of length N. It is used in the theory of coding signals and transmission.

More generally, a Hamming space can be defined over any alphabet (set) Q as the set of words of a fixed length N with letters from Q. If Q is a finite field, then a Hamming space over Q is an N-dimensional vector space over Q. In the typical, binary case, the field is thus GF(2) (also denoted by Z₂).

In coding theory, if Q has q elements, then any subset C (usually assumed of cardinality at least two) of the N-dimensional Hamming space over Q is called a q-ary code of length N; the elements of C are called codewords. In the case where C is a linear subspace of its Hamming space, it is called a linear code. A typical example of linear code is the Hamming code. Codes defined via a Hamming space necessarily have the same length for every codeword, so they are called block codes when it is necessary to distinguish them from variable-length codes that are defined by unique factorization on a monoid.

Code (album)

Code (stylized as C O D E) is an album by British electronic band Cabaret Voltaire. The track "Don't Argue" was released as a single, as was "Here To Go".

The lyrics (and title) of "Don't Argue" incorporate verbatim a number of sentences from the narration of the 1945 short film Your Job in Germany, directed by Frank Capra. The film was aimed at American soldiers occupying Germany and strongly warned against trusting or fraternizing with German citizens.

Ten-code

Ten-codes, officially known as ten signals, are brevity codes used to represent common phrases in voice communication, particularly by law enforcement and in Citizens Band (CB) radio transmissions.

The codes, developed in 1937 and expanded in 1974 by the Association of Public-Safety Communications Officials-International (APCO), allow for brevity and standardization of message traffic. They have historically been widely used by law enforcement officers in North America but due to the lack of standardization, in 2006 the U.S. federal government recommended they be discontinued in favor of everyday language.

History

APCO first proposed Morse code brevity codes in the June, 1935 issue of The APCO Bulletin, which were adapted from the procedure symbols of the U.S. Navy.

The development of the APCO Ten Signals began in 1937, when police radio channels were limited to reduce use of speech on the radio. Credit for inventing the codes goes to Charles "Charlie" Hopper, communications director for the Illinois State Police, District 10 in Pesotum, Illinois. Hopper had been involved in radio for years and realized there was a need to abbreviate transmissions on State Police bands. Experienced radio operators knew the first syllable of a transmission was frequently not understood because of quirks in early electronics technology. Radios in the 1930s were based on vacuum tubes powered by a small motor-generator called a dynamotor. The dynamotor took from 1/10 to 1/4 of a second to "spin up" to full power. Police officers were trained to push the microphone button, then pause briefly before speaking; however, sometimes they would forget to wait. Preceding each code with "ten-" gave the radio transmitter time to reach full power. An APCO Bulletin of January 1940 lists codes assigned as part of standardization;

Pareto principle

The Pareto principle (also known as the 80–20 rule, the law of the vital few, and the principle of factor sparsity) states that, for many events, roughly 80% of the effects come from 20% of the causes.Management consultant Joseph M. Juran suggested the principle and named it after Italian economist Vilfredo Pareto, who, while at the University of Lausanne in 1896, published his first paper "Cours d'économie politique." Essentially, Pareto showed that approximately 80% of the land in Italy was owned by 20% of the population; Pareto developed the principle by observing that 20% of the peapods in his garden contained 80% of the peas.

It is a common rule of thumb in business; e.g., "80% of your sales come from 20% of your clients." Mathematically, the 80–20 rule is roughly followed by a power law distribution (also known as a Pareto distribution) for a particular set of parameters, and many natural phenomena have been shown empirically to exhibit such a distribution.

The Pareto principle is only tangentially related to Pareto efficiency. Pareto developed both concepts in the context of the distribution of income and wealth among the population.

LAW 80

The LAW 80 (Light Anti-armour Weapon 80), sometimes erroneously referred to as LAW 94, is a man-portable, disposable anti-tank weapon currently in use by the British Army and a few other militaries.

Description

The weapon consists of an extendable launch tube with an integrated 9mm spotting rifle and 1× sight. The spotting rifle has five rounds of ammunition, and is ballistically matched to the rocket. The rounds it uses are quite unusual, consisting of a 9 mm tracer bullet loaded in a necked up 7.62mm NATO shell casing, with a .22 Hornet blank mounted in the base of the larger case, providing the propellant charge. Upon firing, the .22 cartridge case pushes out of the back of the 7.62 mm casing, unlocking the breech of the spotting rifle in a form of primer actuation. The spotting rifle on the USMC Mk.153 Mod.0 SMAW was derived from the LAW 80.

To launch the rocket the firer removes the large protective end caps and extends the rear of the launch tube, opens the sight, and moves the arming lever to "armed". The weapon is then in spotting rifle mode. To fire the rocket, the firer moves a charge lever forward with his firing hand thumb. The rocket motor burns out before it leaves the launch tube, the resulting blast being directed rearwards from the launch tube. The rocket then coasts to the target, arming itself after it has passed a certain arming distance. The warhead is a HEAT shaped charge and could penetrate 700mm of Rolled Homogeneous Armour at 90 degrees, as was taught to soldiers trained on the weapon system in the British Army, Royal Navy (Royal Marines) and RAF Regiment. It was also taught that sloped, composite and ERA, would reduce the penetration and would be an important factor when selecting the aiming point.

Law360

Law360 is a subscription based, legal news service operated by the Portfolio Media company, a subsidiary of LexisNexis.

Marius Meland founded Portfolio Media in October 2003 and in 2004 began publishing a daily online newsletter on intellectual property law which he later named Law360. On March 20, 2012, the company was acquired by LexisNexis with Meland and Hoglund serving as co-CEOs. The publication has 11 news bureaus across the U.S.
