  2. Error correction code - Wikipedia

    en.wikipedia.org/wiki/Error_correction_code

    The code-rate is hence a real number. A low code-rate close to zero implies a strong code that uses many redundant bits to achieve a good performance, while a large code-rate close to 1 implies a weak code. The redundant bits that protect the information have to be transferred using the same communication resources that they are trying to protect.

    The article also revealed that representatives of the three largest Xbox 360 resellers in the world (EB Games, GameStop, and Best Buy) claimed that the failure rate of the Xbox 360 was between 30% and 33%, and that Micromart, the largest repair shop in the United Kingdom, stopped repairing Xbox 360s because it was unable to fully repair the ...

    en.wikipedia.org/wiki/Check_engine_light

    When the MIL is lit, the engine control unit stores a fault code related to the malfunction, which can be retrieved—although in many models this requires the use of a scan tool. This warning light can indicate almost anything from a loose gas cap to a serious knock or fault in the engine. [4]

  5. Linear code - Wikipedia

    en.wikipedia.org/wiki/Linear_code

    Codes in general are often denoted by the letter C, and a code of length n and of rank k (i.e., having n code words in its basis and k rows in its generating matrix) is generally referred to as an (n, k) code. Linear block codes are frequently denoted as [n, k, d] codes, where d refers to the code's minimum Hamming distance between any two code ...

  6. The Power of 10: Rules for Developing Safety-Critical Code

    The ten rules are: [1] Avoid complex flow constructs, such as goto and recursion. All loops must have fixed bounds. This prevents runaway code. Avoid heap memory allocation. Restrict functions to a single printed page. Use a minimum of two runtime assertions per function. Restrict the scope of data to the smallest possible.

    On the World Wide Web, HTTP 301 is the HTTP response status code for 301 Moved Permanently.It is used for permanent redirecting, meaning that links or records returning this response should be updated.

    Code 1: A time critical case with a lights and sirens ambulance response. An example is a cardiac arrest or serious traffic accident. Code 2: An acute but non-time critical response. The ambulance does not use lights and sirens to respond. An example of this response code is a broken leg. Code 3: A non-urgent routine case. These include cases ...

  9. Rolling code - Wikipedia

    en.wikipedia.org/wiki/Rolling_code

    Simple remote control systems use a fixed code word; the code word that opens the gate today will also open the gate tomorrow. An attacker with an appropriate receiver could discover the code word and use it to gain access sometime later. More sophisticated remote control systems use a rolling code (or hopping code) that changes for every use.
