Not to mention more water resistant, when printing things like envelopes.

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

Isn't that what tee is for? Like

$ prog | tee /tmp/log.txt

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.

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.

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.

Spoiler alert, it’s Postfix. So not really 1984 software. But then again, neither is Linux…

From one of the blog posts:

> 8080 assembly (Altair 8800) > > First time I've heard of binary-coded decimals

I’m really surprised with that, that someone with such broad interests never heard of BCD. I mean, there’s is always something new to learn all the time, don’t get me wrong, nothing to criticize, just plain surprised. Wonder if that is just something older people came across?

“Give at least five rules to be observed in maintaining good health.”

It would be interesting to know what was the “right” answer to this in 1912.

Hope this goes viral in some way. I think it can make non technical people aware of the problem.
