Isn't that what tee is for? Like

$ prog | tee /tmp/log.txt

When I submit a process to bg, I mostly use cron and I do not care about seeing output during runtime.

So, tail suites my needs in the rare cases something unexpected seems to be happening.

That's if you start the process with advance knowledge that you'll want to tail the output and log it. Not if you want to view the output of an existing process

Yes, but I was replying to the above, using redirection and tail -f.

As others have said, it is easy enough for a child in the 80s, with only a BASIC manual to come up with it. Been there, done that. Didn't even had a name for it. Later I read a magazine explaining several algorithms and found the name of what I had implemented.

For the curious, the ZX Spectrum microdrive listed files on the cartridges by order found on tape. I wanted to display it in alphabetical order like the "big" computers did.

Ha ha, yeah, it was in high school, in BASIC, on an Apple II that I learned how to write a bubble sort.

If cassettes are still around, then the standard icons for 'play', 'rewind', etc will still make sense for a younger generation :-)

The Spectrum did feel slightly better, but the most annoying thing of the ZX81 was the lack of autorepeat. Moving the cursor on a long line was real physical exercise :-)

There should be a t-shirt for that ;-) I remember paying insane prices that year.

Version 1 of Time Machine was great, you could travel to the past and see how your documents looked like! Too bad that they never released version 2. Would have been great to be able to travel into the future and see how your documents would look like.

My first email usage was at University, pre-WWW. After that I briefly used some ISP email service, but that was on a time of very limited storage and POP only accounts, so I started hosting my own email even before having an always-on internet connection, using a relay and dynamic DNS to receive email when online. Now a days, I use a small VPS to route and receive email, but final destination and storage is on my home server. Over the years, I had, like others here, to ask Outlook and other providers to unblock my IP or domain, but it has been rare.

I really don’t want to live in a world where only two or three companies run email for the entire world, and this is my little act of resistance.

outlook.com keeps sending me dmarc reports with failed dkim... while every single other provider gives pass to all domains. at this point I don't even care anymore.

why Microsoft is so crappy?

They have a crappy internal DNS caching server in the email infra that times out early and returns NXDOMAIN for timeouted requests, causing permfail for DKIM instead of tempfail as RFC suggests in case of DNS timeouts. This crap has been going on for years.

They want you to use outlook.

Those wore the days :-) I remember playing on a University lab with half a dozen Unix workstations, sending an email with the path of server1!server2!server3 etc and hearing the email flowing from server to server by the noise of the disks!

Ironic that a big telecom does not believe in decentralized protocols. Oh wait….

Not really, SMTP relays will only send messages once, to one server.

But it’s not receiving that is the problem, that is generally fine, if ports are open at ISP / network level. It is the sending that is often tricky. Sending email on the other hand can be done from multiple servers (if SPF correctly configured) And nothing prevents you from sending email directly from your own relay. You could try that, and reception would not be affected.
