Set it in nm-connection-editor. If that program does not exist on your system, install it.

The lvm command line program at least on Ubuntu, is well documented with lots of help inside of the shell that is created when you type sudo lvm

LVM is a way of organizing disk into volumes on i.a. Linux systems

Great quantum breaking overview by Schneier:
"Maybe the whole idea of number theory—based encryption […] is a temporary detour based on our incomplete model of computing"

"Symmetric cryptography is so much nonlinear muddle, so easy to make more complex"

The "Riot route" router of the Riot project, does not work with Riot.js 4 at the time of this writing. It had to be switched out and I settled for Navigo.js.I have not used it extensively , but here are the changes I had to make, including explicitly unmounting components and respecting that riot.compile is now asynchronous and separate. The code below is for the on-the-fly compiling:

Before with Riot3.js and Riot.route

 <!-- Load riot live compiler for on-the-fly compiling, it compiles automatically -->
  <script src="http://cdn.jsdelivr.net/npm/riot@3.13/riot+compiler.min.js"></script>

  <!--   Load riot's router -->
  <script src="https://cdn.jsdelivr.net/npm/riot-route@3.1.4/dist/route.js"></script>

    route('login', function (name) {
      riot.mount('div#mainview', 'login')
    })
    route('profile', function (name) {
      riot.mount('div#mainview', 'profile')
    })
    route('mytasks', function (name) {
      riot.mount('div#mainview', 'mytasks')
    })

    route.start(true)
    route('login')

And now with Riot4.js and Navigo

 <!-- Load riot live compiler for on-the-fly compiling, it does not compile automatically -->
  <script src="https://cdn.jsdelivr.net/npm/riot@4/riot+compiler.min.js"></script>

  <!--   Load the navigo router -->
  <script src="https://cdn.jsdelivr.net/npm/navigo@7.1.2/lib/navigo.min.js"
    integrity="sha256-EfgFBwdiJuG/NJPYFztHuhSHB1BP4y2yS83oTm6iP04=" crossorigin="anonymous"></script>

  <!-- Configure the router and load initial route -->
  <script>
    const router = new Navigo(null, true);

    riot.compile().then(() => {
      riot.mount('#mainview', {}, 'login')
    }).then(() => {
      router
        .on({
          'login': function () {
            riot.unmount('#mainview', true)
            riot.mount('#mainview', {}, 'login')
          },
          'profile': function () {
            riot.unmount('#mainview', true)
            riot.mount('#mainview', {}, 'profile')
          },
          'mytasks': function () {
            riot.unmount('#mainview', true)
            riot.mount('#mainview', {}, 'mytasks')
          }
        })
        .resolve()

      router.notFound(function (params) {
        riot.mount('#mainview', {}, 'login')
      }).resolve()
    })

Up to €/$/£200 I have found these candidates:

• Sony ICD-TX800 at around 200 €/$/£, a bit on the expensive side
• Olympus VP-10 at around 100 €/$/£, great sound according to Youtube videos, but I've tried the clip and it slides off of garments, so it is out of the race
• Sony icd-tx650 at around 150 €/$/£, seems to have built-in compression that gives a weird pumping effect according to a Youtube video. But this video shows it working great

Background

As an extra precaution, I like to mic myself up with an extra device when I do a presentation or lecture that is recorded to video. It should be:

• A self-sufficient unit
• Discrete and small enough to not draw questions or opinions (but can be clearly visible)
• Out of the way enough to not irritate the person who mics me up with the usual gear
• Equipped with a strong enough clip to stay put in different positions

Another use case is for micing up a person I would interview. In that case it should be:

• Easy enough to place on any garment so that a good recording can be obtained
• Look classy enough so that the subject does not feel uncomfortable with say a taped-together contraption

OpenWRT looks better than DD-WRT too.

A cool idea would be to have an app that summons witnesses to wherever you are, and they film, streaming.

About a year ago I worked in a project where the devs wouldn't have had the time to learn a complex framework such as React.js. They can learn it later if needed. Eventually we went with Riot.js .

Here were some of the initial ideas:

• Prefer existing HTML tags over made-up tags
• Separate html pages for separate, well, pages
• Ability to ony partially take over a page
• Ideally for each html tag, you can specify code for it, and on what events that code should trigger
• Or the other way around, specify for an HTML element, what it is bound to

So here is a list of template/app libraries/frameworks and my initial impression of the learning curve compared to what they can do:

On Linux, put the file names with paths and prefix each with "file" in a file called e.g. files.txt:

file ./foo.mp4

file /bar.mp4

Then

ffmpeg -safe 0 -f concat -i files.txt -c copy concatenated.mp4

There might be a file that just silently thwarts your attempts
