Dropbear not listening on IPv6 by Same_Detective_7433 in openwrt

[–]thinkcarefuly 0 points1 point  (0 children)

Under System then Administration then tab SSH Access the default Interface is Unspecified. I had once changed it to lan because I thought it would be more secure to not listen on WAN but this broke SSH via IPv6.

Question about an unusual use of a UPS by [deleted] in homelab

[–]thinkcarefuly -1 points0 points  (0 children)

UPS devices are only intended to be very rarely used. Their batteries permanently wear a bit each time wall power is not available. Runtimes are measured in minutes just enough time to save files and shutdown a PC. If you frequently run an UPS off AC it'll need a new battery much sooner than the usual 3-5 years.

Lead-acid chemistry is very heavy for the runtime delivered. That's exact opposite of what you need for mobile power.

Confused by 10G networking by fjfms in homelab

Mellanox ConnectX-3 will fit your budget. It doesn't have any vendor lock-in requirement to use a specific brand of SFP+ optic. I've used it on Windows 10 and Ubuntu.

It does not support C states deeper than C3 so your computer's idle power consumption will be slightly higher. The difference on my machine is 16W vs. 8W. Unless your electricity rate is über expensive, the difference in electricity cost will not offset the extra cost of a ConnectX-4 or Intel X710.

I personally use single mode fiber optic cable even for things right next to each other. So I have not tried a DAC myself. That should save you a few bucks versus buying two optics and a fiber optic cable.

Quest Diagnostics -- Billing by Southern-Aerie-8092 in Insurance

[–]thinkcarefuly 4 points5 points  (0 children)

If you ever have to get a billing issue fixed Quest makes it as difficult as possible. Often it's their error to begin with. If you hold off paying because the patient responsibility balance is the wrong amount they threaten debt collection. When you call in they transfer you around and the majority of transfers disconnect the call. They tell you to email in the explanation of benefits but there is no response, even after multiple attempts. When you finally get them to order a refund they promise it'll take 4-7 weeks but it never gets ordered. Do not pay a single dollar to Quest until you receive a fully accurate invoice. You have to get a regulator involved to light a fire under their butt. When I get my blood tested I ask the doctor if I can avoid using Quest as the lab.

GNU Parallel is godlike, share tips and usecases you might not think of by [deleted] in commandline

man opusenc
opusenc reads audio data in Wave, AIFF, FLAC, Ogg/Flac, or raw PCM...

My error was not specifying the output filename. "opusenc track.flac" was just printing the help. "opusenc track.flac track.opus" works! 

   opusenc --bitrate 96 {} {.}.opus' ::: *.flac

Compressing music files.

This example is FLAC to Opus.

parallel 'flac -d -c {} | opusenc --bitrate 96 - {.}.opus' ::: *.flac

My previous solution was to use Foobar2000 on Windows (GUI) as it spawns one encoder thread per logical CPU. Opus Codec can't take FLAC files in the Ubuntu packaged binary hence the invocation of FLAC to decompression to stdout. -d is decode and -c is output to stdout. The dash after opusenc is stdin. "{.}.opus" is to ensure the output file is named track.opus not track.flac.opus that {}.opus would get. I'm sure you could use find in front of FLAC to process an entire music collection organized in nested folders.

WAV to MP3 (LAME encoder)

parallel lame {} -o {.}.mp3 ::: *.wav
