Moderate number of visitors today. One visitor insisted that he bought an IBM PC in 1979. :) I politely explained that it debuted in 1981, but he was adamant about it. He offered to bet me, as if he'd Google it and prove me wrong ... I was tempted to ask how much is in his bank account! Today's best visitor was an 11-year-old who said he codes in JavaScript and Python. Bill I. stopped by to do some preliminary evaluation of the EAI TR-20 that we got last month. It has some parts that he can use to get our other '20 running, including an EAI-branded digital volt meter. Among the EAI documentation, Bill found an unrelated CD that contains an important file which I misplaced several years ago! This time I uploaded the file to Google Drive or safe keeping. I also made some tweaks to our museum network to keep it secure. The new hotspot was set to allow 10 simultaneous connections, but it only needs one connection (to a wifi/Ethernet bridge) into our firewall and the rest of the network. So I changed that value to one; thus even with the credentials nobody can get on that network. No need for any extras, right?
