Transactional programming promises to substantially simplify the development and maintenance of correct, scalable, and efficient concurrent programs. Designs for supporting transactional programming using transactional memory implemented in hardware, software, and a mixture of the two have emerged recently. Unfortunately, conventional debugging programs are often inadequate when employed in relation to code that employs transactional memory and new or modified techniques are needed. We describe techniques whereby certain facilities of a transactional memory implementation can be leveraged to provide replay debugging. With replay debugging, the user can examine a partial or complete execution of an atomic block after it has happened—for example, right before the execution commits. Moreover, in some cases the user can modify the replayed execution, and decide to commit the new modified execution instead of the original replayed one.

A training method and device to suppress sounds caused by sleep and breathing disorders, such as, snoring and sleep apnea. The system records the actual snoring of the subject, modifies it, by time delay and perhaps other sound modifying techniques, and broadcasts it to the subject by a speaker or earphone. This trains the person to attend to his/her own snoring, so that he/she might stop it by moving parts of his/her body or changing breathing patterns. The method and device may include the combination and/or integration of hearing aid functionality and means for detection of snoring sounds.
