The on-line textbook: Information Theory, Inference, and Learning Algorithms, by David J.C. MacKay, contains chapters on elementary error-correcting codes; on the theoretical limits of error-correction; and on the latest state-of-the-art error-correcting codes, including low-density parity-check codes, turbo codes, and fountain codes.
Each steam locomotive was allocated to a particular shed and an oval, cast metal plate (usually 4 + 5 ⁄ 8 in × 7 + 1 ⁄ 2 in (120 mm × 190 mm)) [3] with the depot code was bolted to the smokebox on the front of the locomotive. When a locomotive was reallocated to a different shed the plate was taken off and replaced with one from the new shed.
The locomotives of type 21a were delivered to Vossebanen and are mostly similar to the type 15c . Due to the Vossebahn's many sharp curves, especially the harbour tracks in Bergen, the fixed wheelbase had to be reduced from 12ft 6in (3810 mm) on the type 15c to 10ft 11.97in (3352 mm), and the boiler had to be raised 5.2in (13.4 cm) so the firebox could fit between the two rear driving wheels.

systemd, a software suite providing system components for Linux operating systems, implements a blue screen of death similar to that of Microsoft Windows using a systemd unit called systemd-bsod since August 2023, which was fully added on December 6, 2023 starting with version 255 of systemd. [38]
The speed (or baud rate) includes bits for framing (stop bits, parity, etc.), thus the effective data rate is lower than the baud rate. For 8-N-1 encoding, only 80% of the bits are available for data (for every eight bits of data, ten bits are sent over the serial link — one start bit, the eight data bits, and the one stop bit).
That is the satellites' clocks are slower than Earth's clocks by 7214 nanoseconds a day due to their velocity. Note that this speed of 3874 m/s is measured relative to Earth's center rather than its surface where the GPS receivers (and users) are.
[106] [153] In some cases, police focused on driving while "influenced", pull over slower quartile sober night-time drivers moving no faster than they can stop within the radius of their headlights; [1] this discourages adjusting speed downward from anything but the posted "maximum speed" permitted by law—which is determined as previously ...
