From Throw-Away to Recycle-Use

Reuse, Don't Recycle: Transforming Lock-Free Algorithms That Throw Away Descriptors

In many lock-free algorithms, threads help one another, and each operation creates a descriptor that describes how other threads should help it. Allocating and reclaiming descriptors introduces significant space and time overhead. We introduce the first descriptor abstract data type (ADT), which captures the usage of descriptors by lock-free algorithms. We then develop a weak descriptor ADT whi...

Evaluating ‘Throw Away’ Prototyping for Requirements Capture

This paper demonstrates the advantages of extending the scope of prototyping to the requirements capture phase of a project. Prototyping has long been used to elicit users’ responses to ready-formed designs (Boehm, 1988), but only recently has the use of concept demonstrators (Sanderson, 1997) and early throw-away prototypes (Smith et al., 1990) been suggested as a means to capture response to ...

Throw the stethoscope away: a historical essay.

Am I going deaf, or are hearts not as noisy as they used to be? I’ve had my hearing tested, just some high-frequency loss (probably from that Edgar Winter concert). So I think it’s that hearts are more finely tuned than in the past. I can’t remember the last good S4, the one you could palpate. Or the rumble S3 complex or opening snap you called in the medical students to hear. Many of the wonde...

Keysight Technologies Testing 5G: Time to Throw Away the Cables

From Throw-Away Traffic to Bots: Detecting the Rise of DGA-Based Malware

Many botnet detection systems employ a blacklist of known command and control (C&C) domains to detect bots and block their traffic. Similar to signature-based virus detection, such a botnet detection approach is static because the blacklist is updated only after running an external (and often manual) process of domain discovery. As a response, botmasters have begun employing domain generation a...
