Mast ideas and recommendations
  • Have you tried a 1/4 wave vertical with 4 radials sloping towards the ground? (all wire)? or even a vertical dipole fed halfway up? J-poles show significant coupling to their feedline and mounting arrangements and, as you discovered, are taller than they need to be for their gain.

    US should block cheap Chinese auto imports from Mexico, US makers say
  • There’s no way to be viable against a heavily government-subsidized competitor who operates in a country with little to no labor, environmental, or safety regulation.

    Homelab Switches
  • Cisco 2960S that I got for $100 a few years ago. Works great powering my Ubiquiti APs. Somewhat dated, but it’s always fun to feel like a real “IT Pro” and configure with the Cisco CLI.

  • Attended the Dalton, Georgia hamfest today! Anyone else? Snag any great deals?

    I came home with a well-used Astron RS-35A, which I realize now is emitting a strong cigarette tar odor :(

    Overall, lots of vendors. Some pretty good deals and giveaways, and only a few “random cable drawer junk” / “army clothing” type sellers.

    Would recommend.

    Next up: Atlanta Hamfest on June 1 at Jim Miller park in Marietta.

    Htop too
  • yes, it looks at a fine-grained clock, usually a cycle counter provided by the CPU for this purpose, to aggregate total on-cpu time for each process.

  • I think a lot of modern kernels are “tickless” - they don’t use a timeslice timer, and only context switch on IO interrupt, process yield, or when timeouts are specifically requested (including capping cpu-bound processes). https://en.m.wikipedia.org/wiki/Tickless_kernel

    I tried, I really did
  • Probably dedicated vector/tensor coprocessors these days - which don’t have to work with your monitor layout or desktop setup!

    Instances or networks that focus on forums and conversations instead of link aggregation?
  • Maybe the instance I’m on is wonky, because I can’t even find those communities - I just get the “top”/”default” type communities ala reddit: technology, news, etc, which are all linked mass media articles.

    Instances or networks that focus on forums and conversations instead of link aggregation?
  • I have thought for a while that the next “reddit” should be usenet with a client having advanced filtering, local scoring, etc. Maybe where the client reports to/reads from a shared spam database.

    Instances or networks that focus on forums and conversations instead of link aggregation?
  • I dont mean a chat/conversation-specific community, I mean a collection of communities that are more people interacting than links being posted.

    Especially for hobby, parenting, philosophy, politics, technical discussions, etc.

  • It seems like any platform that features link aggregation is soon overrun by bots and self-promoters trying to drive traffic, and pages and pages of link posts versus pages and pages of people talking.

    Are there any lemmy instances or other defederated networks that focus on Q&A, niche communities, and people conversing, instead?

    Digital-only QRP transceivers
  • Digital modes are usually based on an SSB transceiver, unless you are talking about something with specialized hardware radios like LORA. (In the end, all radio is analog!) So, consider SSB radios even if you will only pass digital signals through them

    Can we really fuel planes with fat and sugar?
  • Plant- or algae- derived oils may work better. The key is to not extract hundreds of billions of tons of hydrocarbons that have been sequestered for 100 million years.
