OT-Just passing this along
by Hopkins, Justin 22 Jan '26

22 Jan '26

I bought a DB25 switch off ebay from a guy in Rochelle Park. Turns out the seller's late father was an electrical engineer and there are "boxes and boxes" of electrical stuff in the house that he has no idea what it is. He put out a few things on ebay, but that is probably 1% of what there is. Here is the description of a few things. Mini-Circuits Attenuator Dynage Power supply TE connectivity 2-221128-1 Pomona BNC to test leads connector Email me off board if you recognize anything and have any interest in it and I'll give you his contact info and he can send you some pictures of whatever else there is. (he is open to getting rid of it in one big lot) There was not any kind of vintage computer stuff except for dual use cables.

Paul Shaffer is the ENIAC Historian at the University of Pennsylvania, where he serves as a steward and interpreter of the world's first general-purpose electronic digital computer. He has spent more than three decades championing the ENIAC artifact - researching its history, preserving its story, and translating its technical significance. A helicopter pilot, Paul brings an aviator's perspective on systems, risk, and disciplined procedure to his work in technology and public history. He is also a commercial UAS (drone) instructor. Paul is known for making ENIAC both legible and vivid: not only as a landmark machine, but as a human achievement shaped by ingenuity, constraint, and collaboration. As ENIAC approaches its 80th anniversary in 2026, he continues to help ensure the machine's technical and cultural impact remains accurately understood, widely shared, and meaningfully remembered.

OT: Why New Jersey Has No Major City
by Herbert Johnson 10 Jan '26

10 Jan '26

I've lived near Trenton for decades but was not born in NJ. So I see the state as an outsider. I appreciated the video. The second half of the video was about "boroughitis", that I figured out by experience, I didn't realize it was driven by policy. But the first half about the (pre)colonial history was new to me and very informative, made sense. I knew previously, that Ben Franklin referred to New Jersey as "a barrel with two corks at either end", being opposite Phila and NYC. And I also knew before, the geography, more than in the video. The state is split north-south by "hills" and rocky lands north, clay and sand and forest soils to the south. I know in particular, the economic value of the southern farms, clays for pottery, sand for glass - a lot of economic value a century or two ago. Trenton was a world pottery center, from vases down to sinks and toilets. Also pine for construction. Even the Pinelands had "bog iron", washed down from the north into the clays. Not in the video, is the fact that ridges run across the north half of the state, from southwest to northeast. They are the ancient foothills and worn-down Appalachian Mountains (mined for coal and iron, other minerals). Rivers and roads run in those directions. They are physical obstacles to north-south commerce, until powered vehicles and asphalt highways were created, except for the Delaware. The Delaware River cuts through these ridges, from northwest to south east in the north half, as the video called out. In the south half, the Delaware bends to the southwest. Roads in either half follow in parallel, or perpendicular-to, the river. Thus there's no "cardinal directions" in the the state - you can't drive "north", you drive roughly parallel or perpendicular to the Delaware. Thus a compass is useless for travel in most of New Jersey. The video called out greater Newark as a single sprawling metropolitan area of millions, bigger than Chicago - that was a surprise. regards Herb Johnson -- Herbert R.

OT: Why New Jersey Has No Major City

*"If you go by pop culture alone, you might think the entire state of New Jersey is just one long turnpike exit—a grey, industrial corridor connecting New York City to... well, anywhere else. It’s the butt of every joke about the state. But if you actually look at the map, and I mean really look at the physical reality of the land, you’ll realize that New Jersey isn’t just a paved-over parking lot. It is actually a geographic marvel that, by all rights, shouldn't exist as a single political entity."* This video talks about it: https://www.youtube.com/watch?v=mzohouMgODo&t=36s Enjoy!

For those arriving at InfoAge for the MARCH Workshop event this weekend, you can open the door to the 9010-D building simply by pulling on the door handle. Even though the door has a code lock, the door is not locked. It's just closed for climate control inside. Jeff Salzman

Re: [vcf-midatlantic] Site-wide wireless for VCF East?
by Neil Cherry 10 Jan '26

I think this is getting way off track and posting blame isn't going to change the network. I take exception with the understanding of what it takes to build a network. I've built very large networks (Corp 50 type networks). I haven't built exhibition networks. Those are two different things. This network is not designed to handle an expo center network, especially on a campus env. Remember this network was built with volunteers and a lot (if not all) was donated. Not a cheap thing, expecially with 10G fiber between the building. If someone wished to cough up the dollars and volunteers to build an expo network, please step up. -- Linux Home Automation Neil Cherry ncherry(a)linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies KD2ZRQ
