How to Debug Chez Scheme Programs R. Kent Dybvig August 2002 When a program fails to operate as it should, it is said to have a bug. A bug is the root cause of an observed behavior, such as failure to terminate, failure to perform some action, termination with an error message, or merely producing incorrect results. The process of debugging a program is one of finding all of the bugs and "exterminating" them. This process first requires feeding the program a representative set of test cases,

Samsung HW-Q990F Soundbar System Review: Glorious Atmos

wired.com Parker Hall 2025-09-21 12:09:00

It’s hard to convince anyone to spend over a thousand dollars on a soundbar system. Ask a home theater nerd or Redditor, and they’ll say spending real cash on anything other than a receiver and dedicated speakers and subwoofer is a fool's errand. As an A/V reviewer, I see this as a hilariously case of gatekeeping. These arguments are predicated on the fact that everyone has the room, know-how, and desire to deal with cables, speakers, and the associated setup. For those of us with partners who

AI Regulation Moratorium Idea Isn't Dead as Ted Cruz Pushes Sandbox Act

cnet.com See Full Bio 2025-09-29 18:28:00

US Sen. Ted Cruz has introduced a bill, the Sandbox Act, aimed at giving companies developing AI technologies a way to bypass regulations by requesting a government waiver. According to the bill, the act would "establish a Federal regulatory sandbox program for artificial intelligence, and for other purposes." In introducing the bill, Cruz said it would allow AI tech to be unhindered by "outdated or inflexible federal rules." In addition to establishing a program for this, the bill, if passed,

Being good isn’t enough 06 Sep, 2025 Giving good career advice is hard. Maybe it’s because careers can look more alike than they really are. Two people can have the same title but what helps one could be rubbish for another. Or maybe it’s that “good advice” itself is fuzzy. It depends entirely on the person receiving it. For some people it means finding work they love. For others it’s about meaning. For many it’s just getting promoted. Still, here’s what I usually say. You have to be good at
