online Join thE convErsation Comments, thoughts, and opinions shared by EDN’s community In response to “Runaway lithium-ion batteries,” an entry in the Dave’s Powertrips blog at www.edn.com/4407381, emc_eng commented: “Lithium-ion battery fires are old news. So, also, is the fact that they are in wide use without problems ... Remember the wing and rudder separation problems experienced on the 787 development? The military side of Boeing tried to advise the 787 commercial folks on the proper way to join composite airplane sections. They have been accomplishing that for years, but their advice was brushed aside. [More than three] major innovations ... at once in a major new commercial airframe project are not recommended risk management. If you are going to innovate on such a scale, you can expect the unexpected, unless you suffer from hubris.” In response to “The current differencing transconductance amplifier,” an article by Jun Xu and Chunhua Wang at www.edn.com/4405810, atemp commented: “Until somebody starts sampling and shipping actual chips that are practical, repeatable, and stable, with lots of competition and drop-in equivalents, CDTAs will join current conveyors and ‘perfect’ OTAs in being purely SPICE or lab curiosities—impractical and irrelevant.” In response to the 5 Engineers question “What’s the most idiotic question you’ve ever been asked during a job interview?” at www.edn.com/4407394, georgegrimes commented: “I was asked, ‘What do you want inscribed on the headstone of your grave?’” EDN invites all of its readers to constructively and creatively comment on our content.
