Analogous storage constraints will be reached in 2106, where systems storing Unix time as an unsigned (rather than signed) 32-bit integer will overflow on 7 February 2106 at 06:28:15 UTC. Computer systems that use time for critical computations may encounter fatal errors if the year 2038 problem is not addressed.
On 5 January 1975, the 12-bit field that had been used for dates in the TOPS-10 operating system for DEC PDP-10 computers overflowed, in a bug known as "DATE75". The field value was calculated by taking the number of years since 1964, multiplying by 12, adding the number of months since January, multiplying by 31, and adding the number of days since the start of the month; putting 2 12 − 1 ...
Integer overflow can be demonstrated through an odometer overflowing, a mechanical version of the phenomenon. All digits are set to the maximum 9 and the next increment of the white digit causes a cascade of carry-over additions setting all digits to 0, but there is no higher digit (1,000,000s digit) to change to a 1, so the counter resets to zero.
The overflow flag is thus set when the most significant bit (here considered the sign bit) is changed by adding two numbers with the same sign (or subtracting two numbers with opposite signs). Overflow cannot occur when the sign of two addition operands are different (or the sign of two subtraction operands are the same). [1]
For example, adjusting the volume level of a sound signal can result in overflow, and saturation causes significantly less distortion to the sound than wrap-around. In the words of researchers G. A. Constantinides et al.: [1] When adding two numbers using two's complement representation, overflow results in a "wrap-around" phenomenon.
An accidental overflow may result in data corruption or unexpected behavior by any process that accesses the affected memory area. On operating systems without memory protection, this could be any process on the system. For example, a Microsoft JPEG GDI+ buffer overflow vulnerability could allow remote execution of code on the affected machine. [1]

Does not work on the MonoBook skin when the browser width is 550 pixels or less due to the body.skin--responsive .monobook-body {overflow: auto;} style that can't be overridden. On Android phones, table headers aren't top-sticky if at least one table using this template is wider than the screen, which is more likely in portrait orientation. The ...
