  • There are at least three legal ways to do this. CB radio, ISM frequencies and amateur radio. I say legal because the radio spectrum is heavily regulated because every transmitter affects everyone else to more or lesser extent.

    You can buy CB or ISM band radios and get started.

    Amateur radio is a better option in my opinion. There are many more frequencies to experiment with, people who can help and people to talk to.

    Amateur licensing is different in each country, but an introductory licence is often no more than a weekend course and exam. I know of nine year olds who have done this. It’s not hard. No Morse code required either.

    With such a licence in hand you can use things like JS8Call, CODEC2, Olivia, WSPR and hundreds of other protocols to communicate using just a radio and a computer.

    Disclaimer: I’m a licensed amateur in Australia and have been since 2010. I hold an introductory licence, here it’s called a Foundation licence, and have been having an absolute blast with all that I can do.

    If you have specific questions, don’t hesitate to ask.



  • I read that you’re manually tagging them, so your process can be whatever you want to do.

    For example, you can leave the images in their current folder structure and create a separate folder structure with symbolic links to an image, so in the character folder would be symbolic links to all the images like that. They also don’t have to be unique, an image can be in multiple categories.

    Alternatively you can use a spreadsheet and generate lists there.

    Finally there are plenty of photo album applications that allow you to tag images.








  • Multiple camera angles are used for two reasons:

    1. Added visual interest. People tend to want variety and colour and movement offered by different views can provide that. This is the obvious reason it’s being used.
    2. Ability to edit without it being obvious. Often a presenter will require multiple takes to “get it right”. If you edit in the take, the picture “jumps” because humans move around. If you have multiple cameras you can edit and switch cameras without it looking like an edit. If you then also look at a different camera when you make a mistake, you can keep recording and fix it when you edit it together.

    My first recommendation is to become familiar with one flavour of Linux. Debian is a solid choice and it will give you a good understanding of how a great many derivatives operate.

    The command line is a tool to get things done, it’s not an end to itself. Some things are easier to do with a GUI, many things are easier to do with the command line interface or CLI.

    Many Linux tools are tiny things that take an input, process it and produce an output. You can string these commands together to achieve things that are complex with a GUI.

    Manipulation of text is a big part of this. Converting things, extracting or filtering data, counting words

    For example, how many times do you use the words “just” and “simply” in the articles you write?

    grep -oiwE "just|simple" *.txt | sort | uniq -c

    That checks all the text files in a directory for the occurrence of either word and shows you how many occurred and what capitalisation they used.

    In other words, learning to use the CLI is about solving problems, one by one, until you don’t have to look things up before you understand why or how it works.





  • In my understanding, deleting (and moderation) are pretty much unsolved mysteries on this platform.

    For example, last I heard, an administrator has to drop into a command line to delete media from removed posts, otherwise they’d still be accessible if the URL was known. (Think illegal material.)

    Filtering is similarly done at the client end, so that’s fun.

    Note that I’m not associated with the source code, only as a user and am repeating things I’ve observed, read, or have been told. YMMV.
