System-level soft errors occur when the data being processed is hit with a noise phenomenon, typically when the data is on a data bus. The computer tries to interpret the noise as a data bit, which can cause errors in addressing or processing program code. The bad data bit can even be saved in memory and cause problems at a later time.
The PDP-10 uses word addressing with 36-bit words and 18-bit addresses. Most Cray supercomputers from the 1980s and 1990s use word addressing with 64-bit words. The Cray-1 and Cray X-MP use 24-bit addresses, while most others use 32-bit addresses. The Cray X1 uses byte addressing with 64-bit addresses. It does not directly support memory ...
Python has array index and array slicing expressions in lists, denoted as a[key], a [start: stop] or a [start: stop: step]. Indexes are zero-based, and negative indexes are relative to the end. Slices take elements from the start index up to, but not including, the stop index.
Canaries or canary words or stack cookies are known values that are placed between a buffer and control data on the stack to monitor buffer overflows. When the buffer overflows, the first data to be corrupted will usually be the canary, and a failed verification of the canary data will therefore alert of an overflow, which can then be handled, for example, by invalidating the corrupted data.
Variable length arithmetic represents numbers as a string of digits of a variable's length limited only by the memory available. Variable-length arithmetic operations are considerably slower than fixed-length format floating-point instructions.
On Mac OS X 10.4-10.7.x, IntelliPoint features can be accessed by opening Microsoft Mouse in System Preferences. [ 2 ] Depending on the software version and specific mouse product, users can define mouse buttons to run any executable program or file they desire (or a control key + letter combination) and can even define buttons for different ...
In most of today's popular programming languages and operating systems, a computer program usually only has a single entry point.. In C, C++, D, Zig, Rust and Kotlin programs this is a function named main; in Java it is a static method named main (although the class must be specified at the invocation time), and in C# it is a static method named Main.
A soft hyphen is only used to indicate where a word can be split when breaking text lines and is not displayed. By placing this halfway in a word, the word gets broken up and will in some cases not be recognised by the wordfilter. Some more advanced filters, such as those in the online game RuneScape, can detect bypassing. However, the downside ...
