I find it such fun to draw upon it in conversation:<\/p>\n<p style=\"padding-left: 30px;\">&#8220;Dave, you know how when Apple transitioned from the PowerPC to Intel, they ran a binary translator, Rosetta (in addition to dual binaries) to keep the the old apps running on their OS. Now that Intel x86 is running out of steam and ARM architectures are looking good &#8211; do you think binary translation will be the answer for backward compatibility or should they just go to virtual machines for emulation?<\/p>\n<p>Dave didn&#8217;t miss a beat:<\/p>\n<p style=\"padding-left: 30px;\">&#8220;Well in a former life I had worked in this. The solution that is the best of both worlds is really register machines. A company that has now folded that came close to that was Transmeta. ARM architectures do look good in terms of power consumption and CPU power. I expect that if they do go down that path virtual machines may solve that problem. But really they can push people to just recompile their apps for the new platform, and that would help them clean all the old apps off their platform that hold them back.&#8221;<\/p>\n<p>I had the privilege of attending the speaker dinner &#8211; and without prompting several people stood up and said kind words about Dave. The one that struck me most was this:<\/p>\n<p style=\"padding-left: 30px;\">&#8220;Dave has a heart for the developers in Australia. There is so much going on in technology, and he wanted to be able to bring that to Australian developers, so they wouldn&#8217;t be left out.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Summary\"><\/span>Summary<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>So your highly caffeinated boss asks you with a sharp-eyed expression on the day after you got back from the conference:<\/p>\n<p style=\"padding-left: 30px;\">&#8220;So.
