Comment: It limits what your debugger can do (Score 1) 174

For simple manual stepping, etc. debugger speed is probably not that important. Have you ever tried to really use watchpoints? Given up after your program slowed to a crawl?

We had a debugger that could run many watchpoints at almost full program speed some time ago, see http://www.netilium.org/~mad/dtj/DTJ/DTJK07/ for details. The key point is that Parasight was fast enough to make tools like this useable.

Natural Gas "Cleaning" Extracts Valuable Waste Carbon 73

The process involves using a plasma reactor to separate hydrogen and methane in the gas. The procedure also turns carbon emissions into high-purity carbon black, a substance that is used to make inks, plastics and reinforced rubber products. Utility companies could potentially sell the carbon black, making the process more financially attractive."
