Can’t stop programming after 60 years so have been writing open-source Python (great language) shareware. What’s interested me are tools to measure network quality and especially tools which Windows users can use since they are unlikely to curl, wget, and sudo when all else fails. I was an early Starlink beta user – 13 months ago – and am still running Starlink although now also have fiber.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>During the late (I hope) pandemic the plight of rural people without adequate broadband for teleconferencing was acute. I am hopeful Starlink will be part of an answer and am both intrigued by its ease of deployment and disappointed by its shortcomings. I am also afraid that the billions the feds are pouring into “broadband” will not result in building the QoS people need to prosper in the hybrid digital world. As all of you know, QoS is much more than up and downlink speed and tough-to-quantify jitter is a huge part of it. My measurement tool zoomready (at <a href="http://freecheckip.com/">freecheckip.com</a> and <a href="https://github.com/tevslin/zoomready">https://github.com/tevslin/zoomready</a>) makes a more or less continuous measurement of jitter but is quite crude; so I’m hoping to learn how to make that better and also how to calibrate zoomready ratings with actual teleconferencing performance. Also would love to learn a way from within the network to determine when obstacles like bufferbloat are in the router and when they’re in the ISP’s network.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I also play with a Raspberry PI for more nerdy stuff but think I add more value making tools available to less experienced users than digging deep into the technologies where many are more knowledgeable than me.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I look forward to lurking on the list but will certainly respond to ideas.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Nice to meet you.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Tom<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Tom Evslin<o:p></o:p></p><p class=MsoNormal>twitter: <a href="https://twitter.com/tevslin">@tevslin</a><o:p></o:p></p><p class=MsoNormal>blog: <a href="https://blog.tomevslin.com/">fractalsofchange.com</a><o:p></o:p></p><p class=MsoNormal>github:<a href="https://github.com/tevslin"> https://github.com/tevslin</a><o:p></o:p></p><p class=MsoNormal>website: <a href="http://freecheckip.com/">freecheckip.com</a><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
