What (who) is C Programmer's Disease - definition

Programmer's Key; Programmer's button; Interrupt button

C Programmer's Disease

<programming> The tendency of the undisciplined C programmer to set arbitrary but supposedly generous static limits on table sizes (defined, if you're lucky, by constants in header files) rather than taking the trouble to do proper dynamic storage allocation. If an application user later needs to put 68 elements into a table of size 50, the afflicted programmer reasons that he or she can easily reset the table size to 68 (or even as much as 70, to allow for future expansion) and recompile. This gives the programmer the comfortable feeling of having made the effort to satisfy the user's (unreasonable) demands, and often affords the user multiple opportunities to explore the marvellous consequences of fandango on core. In severe cases of the disease, the programmer cannot comprehend why each fix of this kind seems only to further disgruntle the user. [Jargon File] (2001-12-31)

Hemoglobin C (abbreviated as HbC) is an abnormal hemoglobin in which glutamic acid residue at the 6th position of the β-globin chain is replaced with a lysine residue due to a point mutation in the HBB gene. People with one copy of the gene for hemoglobin C do not experience symptoms, but can pass the abnormal gene on to their children.

Programmer's key

The programmer's key, or interrupt button, is a button or switch on Classic Mac OS-era Macintosh systems, which jumps to a machine code monitor. The symbol on the button is ⎉: U+2389 ⎉ . On most 68000 family based Macintosh computers, an interrupt request can also be sent by holding down the command key and pressing the power key on the keyboard. This effect is also simulated by the 68000 environment of the Mac OS nanokernel on PowerPC machines and the Classic environment.

A plastic insert came with Macintosh 128K, Macintosh 512K, Macintosh Plus, and Macintosh SE computers that could be attached to the exterior of the case and was used to press an interrupt button located on the motherboard.

Modern Mac hardware no longer includes the interrupt button, as the Mac OS X operating system has integrated debugging options. In addition, Mac OS X's protected memory blocks direct patching of system memory (in order to better secure the system).
