It is mostly short stories on a VERY wide swath of technical issues. Seems to be UK based. It is a weekly of about 40 pages, and the 12/29 article had this article on the cost of AI computing and the way in which computers use so much money erasing data. I only partially understand it but it appears to be well worth reading. Then someone with more knowledge that I can explain it at a meeting.</p><p class="yiv9090076993MsoNormal"> </p><p class="yiv9090076993MsoNormal"><a rel="nofollow noopener noreferrer" target="_blank" href="https://www.newscientist.com/article/mg26435231-300-how-to-fix-computings-ai-energy-problem-run-everything-backwards/">https://www.newscientist.com/article/mg26435231-300-how-to-fix-computings-ai-energy-problem-run-everything-backwards/</a></p><p class="yiv9090076993MsoNormal"> </p><p class="yiv9090076993MsoNormal"><span style="font-size:10.0pt;font-family:Arial, sans-serif;">John Rudy</span></p><p class="yiv9090076993MsoNormal"><span style="font-size:10.0pt;font-family:Arial, sans-serif;"> </span></p><p class="yiv9090076993MsoNormal"><span style="font-size:10.0pt;font-family:Arial, sans-serif;">781-861-0402</span></p><p class="yiv9090076993MsoNormal"><span style="font-size:10.0pt;font-family:Arial, sans-serif;">781-718-8334 cell</span></p><p class="yiv9090076993MsoNormal"><span style="font-size:10.0pt;font-family:Arial, sans-serif;">13 Hawthorne Lane</span></p><p class="yiv9090076993MsoNormal"><span style="font-size:10.0pt;font-family:Arial, sans-serif;">Bedford MA</span></p><p class="yiv9090076993MsoNormal"><span style="font-size:10.0pt;font-family:Arial, sans-serif;"><a rel="nofollow noopener noreferrer" ymailto="mailto:jjrudy1@comcast.net" target="_blank" href="mailto:jjrudy1@comcast.net">jjrudy1@comcast.net</a></span></p><p class="yiv9090076993MsoNormal"><span style="font-size:11.0pt;"><img border="0" width="124" height="115" style="width:1.2916in;min-height:1.1927in;" id="yiv9090076993Picture_x0020_1" src="cid:NDZlJpkey4KwtzTeiltl" yahoo_partid="1.2"></span><span style="font-size:10.0pt;font-family:Arial, sans-serif;"></span></p><p class="yiv9090076993MsoNormal"> </p></div></div></div>===============================================<br>::The Lexington Computer and Technology Group Mailing List::<br>Reply goes to sender only; Reply All to send to list.<br>Send to the list: <a ymailto="mailto:LCTG@lists.toku.us" href="mailto:LCTG@lists.toku.us">LCTG@lists.toku.us</a> Message archives: <a href="http://lists.toku.us/pipermail/lctg-toku.us/" target="_blank">http://lists.toku.us/pipermail/lctg-toku.us/</a><br>To subscribe: email <a ymailto="mailto:lctg-subscribe@toku.us" href="mailto:lctg-subscribe@toku.us">lctg-subscribe@toku.us</a> To unsubscribe: email <a ymailto="mailto:lctg-unsubscribe@toku.us" href="mailto:lctg-unsubscribe@toku.us">lctg-unsubscribe@toku.us</a><br>Future and Past meeting information: <a href="http://LCTG.toku.us" target="_blank">http://LCTG.toku.us</a><br>List information: <a href="http://lists.toku.us/listinfo.cgi/lctg-toku.us" target="_blank">http://lists.toku.us/listinfo.cgi/lctg-toku.us</a><br>This message was sent to <a ymailto="mailto:bobprimak@yahoo.com." href="mailto:bobprimak@yahoo.com.">bobprimak@yahoo.com.</a><br>Set your list options: <a href="http://lists.toku.us/options.cgi/lctg-toku.us/bobprimak@yahoo.com" target="_blank">http://lists.toku.us/options.cgi/lctg-toku.us/bobprimak@yahoo.com</a><br></div>
