Finally, when typing the resulting program into the computer, one might accidentally type a "<" where a ">" was intended, perhaps resulting in the words being sorted into reverse alphabetical order. Most bugs arise from mistakes and errors made by people in either a program's source code or its design, and a few are caused by compilers producing incorrect code. ○ Lettris Embedded systems frequently have workarounds for hardware bugs, since to make a new version of a ROM is much cheaper than remanufacturing the hardware, especially if they are commodity items. The code for attribution links is required. Since the 1990s, particularly following the Ariane 5 Flight 501 disaster, there has been a renewed interest in the development of effective automated aids to debugging.

Others qualify as security bugs and might for example enable a malicious user to bypass access controls in order to obtain unauthorized privileges. More serious bugs may cause the program to crash or freeze. While software products may, by definition, contain any number of unknown bugs, measurements during testing can provide an estimate of the number of likely bugs remaining; this becomes more reliable the longer a product is tested and developed ("if we had 200 bugs last week, we should have 100 this week"). For instance, Thomas Edisonwrote the foll…
