  • The article says:

    The photons travel through a resonant metasurface, where they mingle with a pump beam.

    From that, I think it’s suggesting it needs a separate beam of photons to amplify the signal, much like a transistor needs a supply current to amplify the signal it gets.

    They also say:

    This new tech also captures the visible and non-visible (or infrared) light in one image as you look through the ‘lens.’

    Which sounds like it produces an image showing both the IR and visible spectrum in the visible range.

    Mind you, re-readind it, most of the article just talks about IR, so I’m not certain what it’s actually doing. It could just be transparent to the visible spectrum. It wouldn’t be much good for driving if it did that though, the windscreen blocks a lot of IR and you’d need IR headlights!

    If you have a stove I can definitely recommend heating your pizza in a dry (with no oil) frying pan. Set the temperature medium-low and heat a slice or two at a time for a few minutes. It comes out like it was freshly cooked.


  • The internet in it’s heyday, when it was a genuinely thrilling place to find information, and quite a lot of weirdness, and before it was swamped by corporate interests.

    I remember starting out with gopher and a paper print out of ‘The big dummies guide to the internet’ which was a directory of almost every gopher and ftp site (pre web) along with a description of what you’d find there. Then the web came along and things got really good for a while. Once big corporations got involved it all went down hill.




  • Tmux is a very helpful terminal multiplexer, meaning it can split your terminal into multiple panes. So, create two side by side panes, then one way of doing it is:

    • on the left, run your cmd | tee >(grep 'denied' > error.log)
    • on the right, run tail -f error.log

    The tee process takes it’s standard in, and writes itbto both standard out, so you see all the lines, and the path it’s been given. The >(...) operator runs the grep in a subprocess, and returns the path to it’s standard input pipe, so grep receives every line, and writes the denied lines to a log file which you display with tail in the other pane.

    Rather than using a file for error.log you could also use a named pipe in much the same way.


  • I’m not sure if you’ll see this, as federation seems to be playing up on lemm.ee, but first I wanted to congratulate you on your attitude to life, it’s an inspiration.

    As to your question; I think Obsidian is an excellent tool for you to do this in. As it uses a fairly standard type of markdown for formatting you have plenty of options.

    I’d suggest a two pronged approach to make sure your writing is accessible. In the first place, for the more personal stuff, just print it out. Put the printout in an envelope, write instructions on it that it is only to be opened after you pass away and then mail, or give it someone you trust (a friend, family member, solicitor etc). You can update it by jyst giving then a new copy, or just extra pages to add. I’d suggest making a couple of copies to be sure they get to the people who you want to read them.

    For the general stuff, as Obsidian uses markdown and so does the wiki function on github, you should be able to just commit the vault to your wiki repository and have it rendered reasonably. That way it’ll reflect your changes with little effort. If you’re worried you might do something to it, ask a friend, or acquaintance to fork the repository and regularly sync it. That way you can’t remove all the copies.

    Let me know if you need more detail.
