• The role of division in mathematics

    Posted in Mathy Stuff, Postinfinity Tergiversation on May 02, 2019

    I've written about a certain little-known role of division in mathematics before, so when a friend recently posted an article I enjoyed (having posted a link to it here before), I was pleasantly surprised while re-reading to see that Cohl Furey is also intrigued by division... in a way that sorta links to my own observation. Take a look at this highlighted snippet, from this article:

    Then if you're brave, take a look at my recent adventure with division in a blog post I made a month ago. It's pretty far out there. Have fun.

    [Edit, a little later, after more review of Clifford Algebras, I'm fi...

  • A simple Asterisk and Nexmo setup for a softphone with a remote virtual number

    Posted in Developing Software on Apr 23, 2019

    If you're new to Asterisk, you can spend many hours and even days figuring out how things work before you get something working. And then as soon as you have it working, you'll get slammed by hackers trying to break in. I recently spent those hours and days getting asterisk working. So I have written a quick guide, this one for a connection to Nexmo, where you can sign up for a free account and use it as a SIP trunk to get going.

  • Getting Fail2ban and VoipBL working with Asterisk on Ubuntu 18.04

    Posted in Developing Software on Apr 15, 2019

    The information on installing and configuring Asterisk, fail2ban, and VoipBL is all over the map. It is hilariously not easy to find what actually works. Way more confusing typos and important pieces left out on numerous sites, like there is some sort of conspiracy to make it difficult to install this trio. After trying to install Asterisk from source a number of times and failing for about a dozen different reasons, I finally gave up and used the simple "apt install asterisk" which does not install the latest version of Asterisk, but DOES install a stable, working version -- which ended up be...

  • A fix for apt install asterisk on Ubuntu 18.04

    Posted in Developing Software on Apr 12, 2019

    After using "apt install asterisk" on Ubuntu 18.04.2, I noticed when running "service asterisk status" that there was a problem with the radius radcli configuration. It looked like this:

    radcli: rc_read_config: rc_read_config: can't open /etc/radiusclient-ng/radiusclient.conf: No such file or directory

    The full stack trace looks like this:

    root@:/etc/asterisk# service asterisk status
     asterisk.service - Asterisk PBX
    Loaded: loaded (/lib/systemd/system/asterisk.service; enabled; vendor preset: enabled)

  • An inside-out way of thinking about math

    Posted in Mathy Stuff, Postinfinity Tergiversation, Pre-Preprint Stuff on Apr 01, 2019

    This peculiar thought experiment captures the first time I've been able to completely flip the idea of counting, with a rather original approach. Other attempts have been more high-level, with fewer details, and couldn't be pursued very far. But this time I got to the bottom. Please be patient with this idea. It gets messy at points, but I think the underlying restructuring can be done, even if only as a novelty.

    Note, I do not think my proposal below is a sensible one. It is composed of pieces which don't yet fit together well -- and one of them is completely absurd -- but I'm leaving it in ...

  • An elegant and concise summary of the Cloud of Unknowing

    Posted in Everything on Mar 28, 2019

    I found this brief summary of a well-known mystical work to be compelling. I found it while researching an obscure subject. I set aside the article, and went on with my day. The narrative was so compelling, though, it worked on my unconcious for many hours after I read it. My mind stayed on it through the night, and the next day I awakened still thinking about it. I immediately got out of bed and, no longer remembering where I originally found the information, I searched all my recent history for the tiniest clue for a reference to this linked article, before remembering "apophatic prayer and ...

  • The Place of Humility in Science

    Posted in Everything on Mar 22, 2019

    Always nice to see someone talking about the place of humility in science, as it requires making connections which tend to deepen the general narrative. For example, the article points out where science is being abused by many of its own adherants. This is a thought-provoking perspective, and seems well-defended. Consider this, for example:

    It is impossible for science to obtain a true theory of everything. And the reason for that is epistemological. Basically, the way we acquire information about the world is through measurement. It’s through instruments, right? And because of that, our measu...

  • More on the something and the nearly-nothing and structure

    Posted in Everything, Postinfinity Tergiversation on Mar 10, 2019

    This thread has some very intriguing comments. I particularly like the following two insights, which give empirical evidence relavant to some ideas explored in this recent post by me.

    Penetrating to the origin of structure itself as related to the low entropy at the beginning of the universe

    The Biggest Question in the Universe

    "I personally think that the biggest question in the universe is the one asked by Roger Penrose, which is "How is it that the Universe came into existence with such an incredibly low entropy?" It's the biggest question, in my mind, because that extremely low entropy whi...

  • A parsimonious and fairly logical contemplation on the nature of the beginning

    Posted in Everything, Mathy Stuff, Postinfinity Tergiversation on Mar 08, 2019

    It is utterly impossible for something to arise from true absolute nothing. This can be seen immediately by anyone imagining an infinite expanse of nothing... first comes the paradox of where this nothing exists. It has no dimension, size, shape, form, feature, nor attribute of any kind. It is pure, absolute nothing, nowhere. If this can be imagined, then imagine something coming into being from that nothing.

    It cannot be done.

    There is absolutely no way that something can arise from nothing. Although the mind can actually imagine something appearing out of nowhere, remember, this is happening...

  • On Graduating from Kabbalah

    Posted in Everything on Mar 05, 2019

    It is normal to encounter ideas which we entertain briefly and sincerely, but upon close inspection, later reject or lay aside one way or another. This happens so often that it's hardly a big deal when we reject an idea or constellation of ideas we once thought attractive, although it can be a big deal if we believed an idea for a long time. Like friendships, antiques, and wine, truly good ideas get more precious over time -- and bad ideas more pernicious.

    I will admit it was a big deal to reject an idea which fascinated me for a while early in my intellectual journey when, for example, I rej...
