I have an ancient #Thinkpad that just is not taking to #Gentoo well. I could probably coax it to work eventually, but I don't want to bug the Gentoo IRC channel too much. I can't get X or Wayland running. I tried an #Arch derivative which "works" but is very buggy.

I don't want #Ubuntu with it's crappy snap everywhere setup. I might fall back to #Slackware or #Debian

I just want something that has most #hamradio software in its repos and can run #Wine for #Winlink support.

Would #Forth be good for DSP work? Think implementing an over the air ham radio digital mode protocol, either voice or data. What about SDR firmware?

If I have a properly grounded and bonded shack with a lightning arrester where the coax comes into the house, must I also attach a lightning ground to my antenna as well?

I'm just talking about lightning safety here, not an RF ground or counterpoise, etc.

Is there something like #haveibeenpwned but for banking account info?

I don't mean a credit monitoring service that can (sort of) give you a heads up if bad guys leverage your credit, I mean the hash of [account number] is part of a data set readily available over #Tor or the like.

In Raku this is how I operate on every line of a multiline string:

for $string.split("\n") -> $line {
    foo($line);
}

In Perl, I'd probably do it like this:

my @lines = split /\n/, $str
foreach (@lines) {
      foo($_);
}

The Raku code works, yet somehow it feels less than idiomatic. Thoughts?

@smonff I know you're big into #Perl and know it better than I do. I'm not sure if you know Raku well enough to comment but I figured I could ask.

Feel free to reply with a Perl-lish example, even if it isn't valid Raku. 😀

[#]Rakulang grammar question. Given something like:

[#] Ex. 1
grammar CSV {
    TOP {} # ??
    token column { [ '"' ]? .* \, [ '"']? }
}

[#] Ex. 2
grammar USD {
    TOP {} # ??
    token dollars { \d ** 3 [',']? } 
    token cents   { \. \d ** 2     }
}

1. How do I tell the grammar's TOP that a given token could potentially repeat an arbitrary number of times?

2. Can I mix in range validation somehow? So that 1,234.56 is a valid capture but 0,123.45 is not.

A long time ago, I found several files that discussed connecting the #C64 to #hamradio equipment, typically via the user port. What sorts of things could you do with a C64 and a ham radio back in the day? The details are lost on me, this really was a few decades ago and the files tended to have ASCII diagrams. #retrocomputing #packetbbs #packetradio

I want to run some wire antennas between two trees. If I put a steel I-hook on each tree 20-25 ft up, how do I simultaneously keep the EFHW antennas from drooping and allow for the trees to sway independently in the wind and not snap the wires? #hamradio #amateurradio #antennas

If you were tasked with refactoring the #TMNT #NES game -- the first one -- into a better game, what changes would you make? Assume you're reworking the original codebase on the same mapper as the original NES cart.

Would you drop more B&W TMNT comic references or stick to the Saturday morning cartoon?

Discuss...

Can someone recommend an FRS radio that doesn't suck? I have a pair of Midland FRS radios with 10 minute battery lives and dodgy PTT buttons.

I need:

• As much battery life as possible.
• A PTT button that a child (or a boomer) can work reliably.
• USB-C charging would be a nice bonus.

A bunch of end-fed half-wave questions:

• Is it possible to make a multi-band parallel EFHW? Would that work the way parallel dipoles do?
• Would I have to slope the EFHW? I think that's the only EFHW configuration I've seen.
• How much of a PITA would it be to tune and cut to length?
• Can some wires e.g., 80m/160m, be coil loaded while others are not?
• Would it matter which end had the counterpoise in clothesline-like configuration?

Those of you with an #sbitx do you like it? Unlike the #ubitx does it have an S-meter built in? Is there anything I should know before buying one? I may replace my g90 with it. #hamradio #raspberrypi

Can someone explain why #system76 has open source UEFI firmware but #framework does not? Is open source firmware a goal for framework or is that not really on their radar? It seems like it would be.
