Wootcrisp - Looking into things
 

I think it is helpful to the global perspective needed to address climate change to actually see the increasing number of northern forest fires from the spaceship perspective. Looking down on these eruptions of flame could remind us of the consequences of the consequences of thoughtless behaviours, in particular, the dangerous overheating you might expect from drunkenly red-lining any spaceship making its way through our universe.

 

The summer forest fire season here in British Columbia has been driving me crazy for many years now, and to alleviate some of the nuisance with it all I have tried out many types of consumer products that seemed like they could help. With each of these products I say whether or not I have tried them and I give a subjective rating out of ten.

1. Personal electric air purifier.

A couple months ago I bought a personal electronic air purifier and I think it might actually be useful this summer. 6/10.

4. Fire extinguisher.

I cannot personally testify to the performance of this particular fire extinguisher, but it’s similar to mine, and listed at a pretty good price given that it has free shipping. It’s your classic “A:B:C class” extinguisher: “For use on Class A (ordinary combustibles), Class B (Flammable liquid) spills or Fires involving live electrical equipment (Class C)”. Untested.

6. Indoor cooling.

I don’t recommend portable air conditioners like the one I have for the reasons detailed here:

i) Low cost solution: evaporative “swamp cooler”.

Consumers typically find these things to be underwhelming for several reasons: they raise humidity and they need to be replenished enough to be annoying. I have never used one, but I thought I would include the highest rated one I could see on Amazon in case it interests some readers.

ii) Expensive solution: window air conditioner. 

MIDEA MAW05M1BWT Window Air Conditioner, 5000 BTU. Untested.

7. Bed cooling.

i) Moderate cost solution: directional attachments for your AC unit. 9/10.

Rather than buy an expensive cooling mattress, I have found it fruitful to jam a rectangular duct connector on to my AC unit and run a hose into my bed or to my laptop dock. 

Imperial Manufacturing Duct End Boot 3-1/4 X 10 X 4In GV0650

POWERTEC 70150 Rectangular Dust Hood for 4-Inch Hose

8. Other things I would like to try.

i) Cooling shirts.

Sony launched the Reon Pocket but it’s not available in North America yet for some reason.

If you want to buy a cooling shirt here in North America, you’ll have to settle for something like this:

A small success story for my week has just wrapped up. There is a large, unpopular, academic publishing company named “Elsevier” that, up until now, I have had to accept as an intimate part of life. Several years ago they acquired the pdf organizing app I was using called “Mendeley“. Mendeley was fantastic really. It did everything you wanted it to do, like: rename pdf file names to a standard format like “<author>_<date>.pdf”, store them where you want them stored, automatically fill-out metadata by extracting the article doi, use browser-like tabs for the pdfs currently open, set the proportion of screen associated with an article versus its metadata, export pdfs with standard pdf annotations, easily switch citation styles for bibliography items, not cost anything, shrug it off when you go over your 2gb account storage, and have a basic phone app that syncs and reads the stored pdfs. So when I read that Elsevier had bought Mendeley, I had a good idea of what I wanted when I looked into alternatives: in particular,  the “open” alternatives Zotero and Calibre. What I quickly saw with them, was that they were indeed promising efforts, but they were certainly not the polished F-35 of Mendeley.

First off, both of these programs made you use the system default program for opening pdfs: that is a bad sign. It means there is a disconnect between the program and how the program is being used: like, you’re not going to be searching your pdf comments using the pdf organizer’s search bar, never mind all the other ways a pdf might be annotated by a separate program that effectively becomes a second life for that pdf as there’s no guarantee your pdf organizer will understand or act on these annotations. But, with the use of some plugins and a bunch of reading of the Calibre and Zotero manuals, I could see that one day I would be back to use them for real.

I shrewdly put Calibre on “book pdf duty” since books were too large to keep in the Mendeley library. The basic functionality for organizing the library was there, and the <epub/mobi/pdf> conversion plugin always did me right whenever I would have to immediately kill an “epub” or “mobi” by converting it to pdf.  However, it was absolutely out of contention as my daily driver for journal articles simply based on the fact that doi lookup based file renaming didn’t work out of the box, making new additions to the the library look like a list of “Unknown” and “<!DOWNLOADED FROM EBOK>” titles. Zotero was similarly advertised as an open project, but whatever it may have done better than Calibre, the account you make for syncing was limited to something like 300mb. As it was a problem to configure around this right out of the box I put it aside, but I did decide to keep it, as though it may have felt like riding a wildebeest at the time, it also felt closer to one day learning from Mendeley’s panther style.

Then a few months ago, my Mendeley Android app notified me that it was being discontinued soon, and then it was discontinued and would no longer open. Just like that. I spent years with this app.

Fast forward to this week, and I have now spent months living with the consequences of this amputation. I attempted to put the Calibre database in a Nextcloud folder to sync with my phone, but the weirdness of syncing the database folder while another device is also synced and might also be doing something else to that file was ultimately an insurmountable hurdle for the few hours I had to figure it out.  Was the Calibre Android app really even a good replacement for the Mendeley Android app? A recent sense of urgency pushed me to look into the existence of self-hosting packages for Zotero that might work around the 300mb limitation. There were in fact several options I could see, like a Docker server or one that runs an npm server on port 8081, but as you can imagine I was stoked for neither of those options. And then I found the just released “Zotero beta“, which allows you to sync files privately without storage limits using “webdav” which my Nextcloud server is able to use. So I imported my Mendeley library, synced it to my phone, and in mere minutes Elsevier had finished expelling me as a user.

 

 

The faster I run, the faster my to-do list grows, and the faster I see I must run. Every day I swat angrily at the varyingly important tasks that past me has given to present me.

The task list is in chronological order, chunked by day, using a “*” prefix to indicate complete. Had I proper foresight I tell myself, I would have at least used Markdown when I started it, where instead of a * I would have used “* [ ]” and “* [x]” to prefix each line. There are legitimate pros and cons to consider using Markdown however. In this case the most practical benefits of it are that you can denote headings with # or ## or ###, and a strike-through with ~~[item]~~ but you can also make basic tables and embed images the same way you would with html. However, that latter stuff is a little too fine-dining for a personal to-do list in my opinion, as time is really of the essence.

If you’re needing a professional looking to-do list for work or something, then the trade-offs are slightly different. Pure Markdown has some issues. First, you’ll notice that you need to put two spaces at the end of each line for a line break. That’s not very “time is of the essence” in my opinion. And then you will note that rendering Markdown requires a text editor that can do that, and I will not seriously suggest using pandoc terminal commands for a simple to do list, and for a more exaggerated form of that same reason I do not recommend reStructured text for a to-do list. So for text editing I recommend Atom  as it has quite a buffet of packages that are easy to install and allow you to do things like mix Markdown with Latex. While this can tempt you into breaking convention—and therefore portability—because of the idiosyncratic set of packages that will be needed to properly interpret your document, it is easy to imagine recovering that portability with a series of package installation calls at the start of your document like so:

apm install language-latex
apm install language-markdown

I should also note that QOwnNotes  has treated me well for many years as it is very specifically designed to sync with Owncloud/Nextcloud and I’m hesitant to uproot that system for something like “atom-ownsync” which doesn’t seem to get updated very often.

 

It’s about that time of year where I check in with my mirror dance progress by dancing to the same music that was in my first videos.

2020 original (bad audio): 

2020 director’s cut: 

Last year’s: https://wootcrisp.com/2019/03/05/three-year-mirror-dance-progress/

At first I wasn’t sure what to think about this dance, but now that I’ve just given these videos my undivided attention, while sitting comfortably in the bath with my new bath shelf, and using some nice new headphones I was given for Christmas, I will indeed say that that the dance has its quality moments.

Also, in exchange for a free battery, I will also say that the particular Bomaker “CA-Dolphin Ⅰ” headphones I just watched the video with were worth doing business with, given that I don’t know anything about how they were made. I really would like to believe the company is wholesome, but in this matter I haven’t got a clue as to how I could actually learn something about the company “Bomaker“.

This kind of endorsement uncertainty reminds me of a website I developed about a decade ago: GreenAds.org. The success of a product submitted to this site was based on a combination vote_count and a green_score to rank products similar to something like Reddit. Individuals were incentivized to submit good products because they could include their affiliate id in the url, and publishers could serve a feed of popular items in their banners, swapping in their own affiliate codes in the product feed:

I recently managed to misplace all the code from GreenAds but that’s okay since it was garbage code anyway. The project that motivated GreenAds was Vidipedia.org, and there’s a bit more information about both projects at this Patreon I’ve been trying to work on when I have time: https://www.patreon.com/vidipedia

One of the ways I’ve been procrastinating recently is by thinking half-heartedly about Rubik’s cubes. I’ve never solved one, and don’t want to learn the algorithms, so I slog through some trial and error with it every now and then. To inspire a recent attempt, a few months ago I opened up the chapters on “Cubology” in “Metamagical Themas“, skimmed through some of it, then put on the Go Pro, and gave a newly acquired 2x2x2 cube the old college try. In what seemed like the blink of an eye the Go Pro was out of battery and I was sitting on near 18GB of boring footage from several attempts.

This scared me enough to not try again for a few months, but my mind has returned to the topic twice since then, and it recently led to a possible coincidence.

The first time my mind returned to the Rubik’s cube is an aside from this story, but I think worth mentioning and should be of interest to the general reader. I was trying to think of a more dynamical way to connect a set of neural fields such that each field doesn’t have to be fully connected to each of the other fields in order for them to be jointly capable of representing their entire space of combinatorial possibilities. The “dynamic neural field theory” (DNFT) approach to cognitive representation can already incorporate something like this in two ways. Multidimensional representations are typically decomposed into a set of fields that maintain bidirectional projections with each other through a common field. This is very useful because neural fields with more than 2 dimensions are challenging to simulate [1]Possibly the only “integral” 3-dimensional construct that we have is “colour”, according to \textcite{Shepard2001}: “We may need three dimensions of color not because the surfaces of objects vary in just three dimensions but because we must compensate for the three degrees of freedom of natural lighting in order to see a given surface as having the same intrinsic color regardless of that illumination”.  It’s a very complex issue, but I often return to the 4-layer colour encoder-decoder network reported in \textcite{Lehky1999} when I’m trying to think about modeling representations of colour: “A particular ratio of activities in the population of wavelength tuning curves is assigned the label “white,” and the distribution of wavelengths that caused it does not matter. The set of all labels forms a qualia space. In this way the system avoids dealing with a difficult inverse problem and instead does something simple but perhaps behaviorally useful. Information is lost in this process, but the information that remains appears useful enough that there are evolutionary advantages to developing such systems.”. In this talk by Sebastian Schneegans we can see  some methods to bind representations across 3 feature dimensions, like, for example, with 3 separate 1-dimensional fields, and a single 2-dimensional field, similar to what’s happening here:

 

In combination with a kind of “use-it-or-lose-it” strengthening and weakening of the connections between these fields—“competitive learning”, “sparse coding”—the computational burden is lessened dramatically. But this is not quite what I had in mind when I was thinking about Rubik’s cubes. Rather, I wanted some way to go from a representational space with a fixed frame of reference for each field, like small-medium-large, to a relative frame of reference like small_fruit-medium_fruit-large_fruit, via a sequence of discrete operations on just the actual set of fields themselves. Naturally, this made me think of the Rubik’s cube again, with the faces being a set of 6, 2-dimensional fields. I think it could be useful to think of each “facelet” location on a face of the cube as having a receptive field centered on a “preferred” distance for the transforms that move that facelet to a location on another face. The decision to rotate the cube in a particular way, would originate from integrating activity for each location, given that location’s rotation distance “preferences”/receptive-field. It’s weird to think of Rubik’s cubes solutions as requiring decision procedures based on this. Now before you say “it’s not weird that the Rubik’s cube solver would need a decision procedure using information like that, and it’s irrelevant to what a Rubik’s cube metaphysically is”, let me discuss the next time I thought of the cubes.

The second time I thought of the cubes since my failed attempt at solving the 2x2x2, was this evening, as I tried to wrestle my mind into focusing on something properly erudite. I opened Metamagical Themas once again and began reading “Magic Cubology” in earnest. In particular I was looking for the page containing that most interesting of anecdotes about Rubik’s Cubes that I had never forgotten: Rubik’s cubes are thought to be a model of quarks. I wanted to photograph this page for a new collection of curiosities that I’m putting together, possibly as a daily picture site.

It was just at this point, that my girlfriend came in the room and asked if I wanted to finish watching “Planes, Trains, and Automobiles” with Steve Martin and John Candy. This is where the coincidence happens. A few minutes into the movie, my mind conjured up an old picture of Steve Martin holding “Metamagical Themas”:

 

What are the chances? We had been watching the movie a bit last night, so Steve Martin likely activated the idea I have of him as being an erudite celebrity, and I think he does look a bit like Douglas Hofstadter, but…Metamagical Themas was also laying next to my bed from where we watched the movie so that might have suggested the movie in conjunction with Thanksgiving time. Alternatively, I had been humming and hawing over whether to make a “daily curiosity” site or just a montage of curiosities as part as an art piece in an upcoming gallery I’d like to release in time for Christmas. This humming and hawing may have provoked me into opening the book this evening, and the memory of Steve Martin’s picture may be a genuine coincidence.

Human beings face doom if they do not quickly reorganize society to improve their chances of survival. Inexplicably, business as usual—where we create, for example, arbitrary amounts of drones for personal amusement, deep-fakes to obliterate any definitive notions of accountability for what we may or may not have said and done, and a plethora of smaller and more exciting recording devices that, intentionally or not, record everything going on around them—is challenging our notions of “survival beyond 2030”. 

Given this state of affairs, it is infuriating that the public discourse has yet to realize that VR has all the answers. So, as an exasperated response to the numbing number of “How to survive/cope” articles I see all the time, e.g., [1][2], I thought I would explain why VR is providing the means to search for the right answers to many of society’s interminable problems. 

Simply stated, the problem is that we must somehow engage ~8 billion people with a role they can play in what Buckminster Fuller called the “operating manual for spaceship earth”. There is no formula for this, so it is easy for a society to start playing nihilistic language games based on the relativity of “solutions” to “our” problems. From here, Fuller tells us only that “you never change things by fighting against the existing reality. To change something, build a new model that makes the old model obsolete”.

Well, in this case, the old model of societal decision making can be likened to an optimization process called “grid search”: we imagine a space of possibilities, and we expand this space to make an “informed” decision only when something in particular doesn’t seem to be working. Like how we collectively addressed the hole in the ozone layer through specific multinational agreements when it was clear how dangerous the situation was.  

Grid search is passé. Bayesian search theory (BST), changes everything, from how we look for lost nuclear submarines in the Atlantic, to making evidenced-based changes to how we teach professions as esteemed as radiology. The principles of BST can be understood simply using the toy game “Battleship”, where it is obvious that random firing is not the best way to play. It is much better to integrate what you know about the number and size of the ships you need to hit,  along with where you’ve already fired, in order to maximize the probability of a hit:

 

From Vsauce2 and a blog post.

We know from work like \textcite{Kahnmen1973, Holmes2014} that human beings often do not do the “optimal thing”, yet they also seem to “succeed” nonetheless. This is because there is always an ad-hoc “optimal” way to have arrived in a situation, but to give the term any kind of prospective meaning requires specifying a commitment to a goal in advance. BST methods tell us that this specification requires a kind of “imagination”. An ideal search must occasionally check out strange places—called “exclusion saccades” in vision research—as part of committing the searching agent to an imagination that makes some locally “non-optimal” decisions in order to find a more optimal global solution. 

The optimal global solution for human life in this moment requires that academia in particular unifies behind the outlandish goal of global adoption of virtual reality headsets. 

From Terrarium VR, and my own Virtual Explorations

The easiest way to get billions of people to commit to achieving something, while not moving around and causing so many problems, is with a seductive and self-reinforcing technology like VR, that can satisfy a range of goals by maximizing creative potential as well as the freedom to be totally uncreative. With this incredible tool, people can at least have the option of managing their habitat with surrogate devices and try to make a positive difference by learning about, and applying, principles of optimality with their neighbours in the process.
