Here's an eclectic mix of examples from various perspectives across multiple domains. Understanding the representation of knowledge and the fundamental structure that underpins the connective essence of things is one of the prime ideas that drives my thinking, and as a consequence much of what I post about on here is related to that in some way. Below is a brief sampling of examples related to this idea, and for a more extensive list, browse through my postings (and if you can see how they all connect, let me know!).

In general, see the Classification of Finite Simple Groups [0]. In terms of specific examples, the minimal classifications of knots [1], trees [2], and braids [3] are 3 instances that popped to mind. From a number-theoretic perspective, the paper Enumerating the Rationals and its derivative works are interesting reads. In terms of spatial structure and spatial decomposition, look at the classification of crystal structures [4], lattices, polytopes (zonotopes are particularly interesting), periodic and aperiodic tilings, the classification of space-filling curves, and the classification of closed surfaces [5]. From a relational perspective, look at the classification of topological spatial relations [6] and Allen's interval algebra [7]. And the one my intuition finds most intriguing is the classification of Group Theory Single Axioms and its relation to my conjecture that division is primary.

Got any thoughts on the use of pillows?

A pain in the small of my back went away after I started sleeping on a hard floor with a thin mattress-pad underneath. The discomfort was brutal the first week though.

I still love using my big squishy pillow tho, because I like sleeping on my side.

I know that sleeping without a pillow has to be good for me... 2 million years of homo-noid evolution without pillows is all the facts I need.

However, the most I'm able to go without a pillow is 2 nights. I have such terrible sleep, that I give in and use a pillow the 3rd night.

Without a pillow I find I can't sleep on my side (which I love doing), and if I'm sleeping on my stomach then there's too much pressure on whichever face-cheek faces down, causing mild bruising.

I'd love to learn to stop using pillows though.

It's worth noting that in its heyday --- usage on Gab appears to have plummeted, at least measured by the front page, and seems to be dominated today by bots --- the content on that page was absolutely par for the course for the front page of the site. There was even a House candidate, Paul Nehlen, who campaigned using almost identical anti-Semitic rhetoric on Gab.

You wouldn't want to leave anyone the impression that this kind of stuff was somehow buried on individual user pages on Gab. Rather, it is the raison d'etre for the whole site.
Not at all. This is more like judo combined with yoga. Meditation is about youe mind, feldenkrais is more about movement and muscles.

I have no idea to be honest. I just gave a nominal amount, think it was like a hundred dollars. I would happily give a LOT more if I had stronger financial means / if I thought it would actually have an impact.

It seems like they're mostly seeking funding from larger institutions, as crowd-funding such a large research effort isn't really feasible or sustainable.

Gab is a free speech platform.

This really was a very good talk. It was delivered at a speed which I could keep up with and at no time felt overwhelming, but we still covered a huge amount and I learned loads!
I hope that ICOs or some other jobs act legislation will make it easier for ordinary investors to get early access to the market. I also hope for tax legislation that would make exercising options cheaper (e.g. pay the tax at a liquidity event, instead of based on the difference from fair market value at exercise when not liquid. These two things would dramatically improve the current situation.
Gab has been described as Reddit for Racists.

A quick glance at Gab seems to show a large number of hate groups.
Perhaps PayPal simply do not want the fallout that might ensue from that association.

Google has already removed the Gab app for violating their hate group policy. Apple and Twitter have also removed them.

Can AI Find an Alien?
Ha! For my first guess, I randomly picked year 1762, and that year was the first known use of 'entrepreneur': https://www.merriam-webster.com/dictionary/entrepreneur

So I looked up "venture capitalist", which redirected me to "venture capital", which has a first known use in 1943.

"digital" doesn't have a specific year, M-W just says "15th century", but the first known use wasn't for 'fingers', it did originally have to do with calculation: https://www.merriam-webster.com/dictionary/digital

"computer" is 1613, in the form of "one who computes": https://www.merriam-webster.com/dictionary/computer

And, just as important, "coffee" is 1598: https://www.merriam-webster.com/dictionary/coffee

Sounds terrific. However, it feels like a lot of what they have achieved is marketing existing ideas that were already great, with improved packaging, but in a way that ultimately isn't practical.

Because truly plug-and-play components are an awesome idea. However they are not a new idea at all. As far as I can tell the real reason they are not more popular is because us programmers are worried we will be accused of being users if we use tools that are interactive. See Visual Basic 6 (which was an amazing system). Of course programmers do not realize this psychological issue exists and will not admit it is a possibility.

But in the context of Bret Victor's lab with the projectors and little pieces of paper, that puts plug and play components in a different category that makes them more palatable.

Also, projector based AR is much more convenient for people to demo than HMDs, but also not very practical for widespread deployment. But AR is amazing in general and this allows them a friction free way to demo its power with components.

But I think that multiplayer real-time collaborative interactive component based AR programming should definitely be a more common thing. It combines the advantages of all of those techniques. I also think though that all of those things are useful in lesser combinations. I believe a big part of the reason at least some of those things are not used more or more effectively is cultural or psychological rather than technical or practical.

The thing is the more you take advantage of components and interactivity the less you use the complex colored encoded text. That means programmers can spend a significant amount of time snapping together components and configuring them. Unfortunately programmers are not able to recognize this as programming. We have a feeling the more we do it the more we may lose our special incanter status and be classified as users.
Sure, vw can do it, match tesla. So can audi, gm, bmw, mercedes, etc. Yet these companies haven't done it. Even the new ipace is less that my 2012 Dec Tesla 85kwh S. It's 6 years later and they haven't matched them.

> Wouldn't this proposal cause nations that adopt it to shift their weekdays from nations (and religions) that don't, at the rate of one a year?

Yes, and this is the primary problem with the 13mo/yr proposal, even more intractable than the constant month/day conversions between countries that would result. The "1 day of rest per week" (which is inseparable from the 7-day cycle) is very important to a large segment of the world's population, especially Muslims, Jews, and Christians.

I'm with you on that, but in this specific case people are using Edge exactly once on a new machine in order to download Google Chrome. It's reasonable to assume they aren't going to bother installing an ad blocker on Edge for this use.

Both concepts are definitely being misused/overused, one is "dated" and the other "modern", but surely the middle ground where best usage of both can be attained is prefered.

This really works. I had lower back pains from working on laptop with head looking down. Took two days workshop and on the second day all the pain was gone. Now every time I feel minor back pain, ten minutes of certain pelvis exercises and all is gone. Feldenkrais method birthed many more modern, specialized methods for example Anat Baniel for kids with mobility issues. I was really thinking its crackpot stuff until I tried it.

I cured 30+ years of back pain caused by walking recently by... standing up straight when I walk. Not trying to be funny here. Sitting has never caused problems because since the early 80s I developed perfect desk posture to avoid back pain. However, I never noticed until recently that I stooped over a little when I walked, which I do for at least an hour a day. Straightened up and boom, no more pain after walking.
It's funny you say that. This is something Alan Kay talks about at length. For example, watch the first 20 mins of this talk - https://www.youtube.com/watch?v=FvmTSpJU-Xc

Essentially, he asserts that computing (or computer science even) isn't a real field (like biology or physics). Most people can't name the early computing pioneers whose work they build on (not true in Physics or Biology, we celebrate the pioneers) nor are they familiar with the work that was done in the Xerox PARC days.

It's gotten so bad that a lot of computer science research just assumes that what we have now is what's going to remain forever. In the 70's, all kinds of interesting ideas and experiments were tried.

Hardware implemented VM's, direct manipulation programming, OS-free computing environments, highly re-configurable computing a la FPGA's, and hundreds more.

Nowadays, we think that creating custom ASIC to run machine learning algorithms quicker is innovative and novel.

All this to say that many of the ideas in Dynamicland aren't new. They're rooted in ideas that are decades old. If you look at Bret's papers he uses as references frequently, you'll notice how many of them are over 10 years old - http://worrydream.com/refs/

Explanation for the spoofed domain name: https://twitter.com/sephr/status/1055751684146655232

Bing can easily fix this domain spoofing vulnerability. I've reported this vulnerability to MSRC previously but received no response.

This is also why open redirects can be so dangerous. Even if this domain spoofing vulnerability is fixed on Bing's end attackers can abuse open redirects to achieve the same result.
That's pretty dismissive and combative. From a neutral perspective, it looks like one of the intrinsic characteristics of Gab is that it is host to more hateful expression than other platforms. Can you give something in the way of an explanation as to why you're so confident that can't be the real reason?

Nobody wants to hold their money at 90% for perpetual timelines without returns as the issuers plays 'Dirty' regulatory game of 'partially subscribed' gateway. Me lost precious investment under such scam (legit as law permits)- better buy shares direct from the market; when companies bleeds with outright /TITLE/, than waiting for the mercy of issuers. It was a rampant practice in 90ies and 2YK decades. We are still suffering.
How is yoga going to strengthen the muscles? I thought it’s for relaxation, no? Unless you are talking about some non traditional yoga.

I think this implies that degrees in history or philosophy and such are always worth very little and a degree in eg mathematics is always worth a decent amount.

In terms of the money the students earn in their later life, this is definitely correct. Society simply does not fund jobs not "contributing" to the economy in a sustainable way - for example, caregivers for both young and old people, teachers or social workers are paid shit, while a total dumbass can earn tons of money as a "consultant"...

Instead of using brackish regions like river deltas, wouldn’t it make more sense to setup clusters of floating “lily pad” style DC power plants in tropical areas where the coast experiences regular heavy rainfall? The fresh water would sit atop the surface membrane due to its’ lower density and slowly filter through to the ocean surface. DC could be converted to AC onboard floating stations and transmitted to coastal regions using ocean floor cables.

And I think your comments come to the real problem for people with controlling greenhouse gases. My dad is in this boat. He might say "I deny that my actions hurt the earth. I don't want to look at the evidence, and I don't trust anyone who says I might be doing damage by driving a gas guzzler. I deny I could be hurting things. I refuse to believe anything that leads to that conclusion".

You can usually disable atime if you have performance concerns, so it's not really that big of a deal.

I'd say a clear failure of the unix legacy is that file creation time wasn't tracked. You only had atime, ctime, and mtime.

On macOS you can only access st_birthtimespec with stat(2) if the `_DARWIN_FEATURE_64_BIT_INODE` macro is defined.

A quick search shows most newer filesystems support birth or creation time:

* Btrfs: otime
* ext4: crtime
* UFS2: st_birthtime
* ZFS: crtime

Torba had an unrelated YC startup during the batch that was running during the 2016 election season. He was ejected from YC for harassing batch-mates; there's an HN thread about it you can find in the search bar. He started Gab at just about the same time as he was kicked out of YC.
I think this is missing the forest for the trees. The audience for these tools is people who have never written in a text editor in their life! They literally might not even recognize that some fonts are fixed-width and not know what textedit is.

That is to say, emacs might be over-kill. But literate programming is a pretty powerful concept in general, and rmarkdown and Rstudio (along with simliar tools in Python, Julia, etc.) make this super easy, and I think its a great way to introduce people to programming.

Getting people to use Git is the fight worth having imo, but its still hard. I was talking to someone the other day who didn't like git because tough to have comments about the work: they didn't use code reviews on github to get consensus, just comments in the code.

Plus there is the whole data-management problem. Quilt, SQL connections, and DataDeps for Julia are good solutions, but there isn't a single one answer that we've coalesced behind.

These are all really tough problems. I'm actually really interested in MS's acquisition of github for this reason. Maybe they can put some money towards the obstacles that have prevented mass adoption of scripting and git.
There is some truth in those comments, but it's also true that climate change is real and we are accelerating it with our choices to burn more carbon based fuels. It's basically undeniable at this stage, yet people whose lives are inconvenienced by it deny the truth. You cannot and should not use problems in certain papers as an excuse to deny the inexcusable.
