Colossus, the Second World War computer, today successfully deciphered a coded message transmitted from Germany, recapturing the drama and excitement of Bletchley Park’s code-breaking legacy.
Experts using the newly-rebuilt machine at the National Museum of Computing in Bletchley Park, Buckinghamshire, managed to beat a number of rival code breakers using modern-day computers.
But, more than 60 years on from when it helped secure the Allied victory in the war, today’s Colossus team had to doff their caps to an amateur enthusiast from Germany. Joachim Scheuth, a computer enthusiast from Bonn, was first to crack the message using a program he wrote specifically for the National Museum of Computing Cipher Challenge.

“Extraordinary news for computer scientists and the Open Source community was announced over the weekend, as the source code of the MULTICS operating system (Multiplexed Information and Computing Service), the father of UNIX and all modern OSes, has finally been opened. Multics was an extremely influential early time-sharing operating system and introduced a large number of new concepts, including dynamic linking and a hierarchical file system. It was extremely powerful, and UNIX can in fact be considered to be a ’simplified’ successor to MULTICS. The last running Multics installation was shut down on October 31, 2000. From now on, MULTICS can be downloaded from an official MIT site (it’s the complete MR12.5 source dumped at CGI in Calgary in 2000, including the PL/1 compiler). Unfortunately you can’t install this on any PC, as MULTICS requires dedicated hardware, and there’s no operational computer system today that could run this OS. Nevertheless the software should be considered to be an outstanding source for computer research and scientists. It is not yet known if it will be possible to emulate the required hardware to run the OS.”

El valor inicial para AUTO_INCREMENT para la tabla. En MySQL 5.0, sólo funciona para tablas MyISAM y MEMORY. También se soporta para InnoDB desde MySQL 5.0.3. Para inicializar el primer valor de auto incremento para motores que no soporten esta opción, inserte un registro de prueba con un valor que sea uno menor al deseado tras crear la tabla, y luego borre este registro.

Para motores que soportan la opción de tabla AUTO_INCREMENT en comandos CREATE TABLE puede usar ALTER TABLE tbl_name AUTO_INCREMENT = n para resetear el valor AUTO_INCREMENT .

SELECT LAST_INSERT_ID();
