GuiA··on Personality Vectors (2019)
Rederived from... what? A comfy armchair? The blog post chose to use vector math as its starting point but I’m not seeing any data that validates the approach in anyway, or anything that justifies it besides the assumption that “ You can take preferences and combine them into a single value/point on a vector” - which you can, but how meaningful is it really to say that my “dog preference” is 0.9? Why not model people with irrational numbers, regular n-gons in 24 dimensions, or a directed acyclic graph instead?
GuiA··on Personality Vectors (2019)
Which is all very silly since OKcupid will incorporate dealbreaker questions like “how important is your partner’s religion to you” with ones like “do you like horror movies”, and thus you may end up matching at 90%+ with someone whom you would never consider dating.

GuiA··on I'm Married to an ER Doc in NYC
Streets were crowded in SF's mission tonight too, with many people 1) not wearing masks (or wearing the mask on their chin (!?!)) 2) being in close knit groups.

Fingers crossed I guess, but given that 1) the virus is still around AND 2) we do not have a vaccine AND 3) we do not have herd immunity, I can't say I feel very optimistic about the next month or so.

Ah, thank you. That's handy phrasing.

GuiA··on How the Magic: The Gathering Color Wheel Explains Humanity
“When you light a candle, you also cast a shadow.”
GuiA··on How the Magic: The Gathering Color Wheel Explains Humanity
The human brain loves finding patterns, meaning, and explanations ("the platonic rises to the top", per Taleb), so you'll be able to do something like this for pretty much any configuration of objects (all numbers are interesting after all! [0]).

One could write a similarly convincing post about how the Terrans, Zergs, and Protoss embody the 3 core pillars of humanity, complete with esoteric looking diagrams. Read some Carl Jung, some Joseph Campbell, some TVTropes, and you too can make your own grand unifying theory of human psychology at home!

The real insight for me came when I learned to hear what people were really saying, when on a first date or job interview or meeting at a party, they were telling me they were INWP or enneagram 14 second wing or a Capricorn rising Gemini.

GuiA··on Human-Level Intelligence or Animal-Like Abilities? (2018)
We have billions of examples of babies growing up to learn to spell and tie their shoes, therefore it's very reasonable to assume that that's a skill most babies will get to.

There are 0 examples of a man made construct reaching "general" intelligence (whatever fuzzy meaning you may attach to it); there is no reason to believe that because we can reach some arbitrary human milestone today ("be a world class Go player"), any other human milestone ("start and run a company, and be a mentor and inspiration to others") is plausible.

This is a very different case from e.g. "we built a prototype plane that can lift 15 ft off the ground for 10 seconds, we should be able to build one that can lift 10,000 feet for 10 hours", because in the former case we were beginning to have an understanding of aerodynamics that made that path plausible. We do not have such an understanding backing current ML work. That's well illustrated by the fact that only 6 years elapsed between the first manned flight and crossing the Atlantic by plane - practice caught up to theory really fast, as it tends to do in those cases. We are about 6 years in the current ML revolution - what is its equivalent to crossing the Atlantic?

The logic you're advocating for here is more along the lines of "I taught my dog how to sit - shouldn't be too hard to get him to sit in front of a computer and start writing Python code now that I've got the first half figured out".

(or - I taught my dog how to fetch - shouldn't be too hard to train him to be a full time food delivery employee, etc).

GuiA··on Ask HN: I implemented the life I designed: perfect but I feel lost. What now?
Life is like a piece of music. The "point" of listening to it lies in the listening - not the getting to the end of the track. If you build and optimize your life around "getting to the end" - whatever that has meant for you, getting a degree, reaching a certain amount of wealth, a certain amount of success, a certain kind of partner, etc. - you will eventually find that there is no more "end" to get to.

Well, the way out of this is really stupid - you just have to learn to enjoy the music instead of always looking forward to reaching the end of the track.

GuiA··on Most tech content is bullshit
I took a grad level course on data mining/machine learning back in the early 2010s, before the current gold rush, and while there was some level of theory and programming, the professor spent a lot of his time discussing these finer points. The (apocryphal) example of armoring planes in the wrong spots [0] sticks with me to this day.

It’s human nature to focus on the more immediate, tangible outcomes - eg going through a pytorch tutorial - over spending time trying to really understand the problem they are trying to solve. Great teachers try to guide their students there, and great students are perpetually calling themselves out mentally to try and stay on the track of understanding rather than rote repetition. But it’s very hard.

GuiA··on Life as Thermodynamic Evidence of Algorithmic Structure in Nature (2012)
There are pretty compelling reasons to believe that life/physics are strongly tied to computation. See eg the slime molds experiments for some of the more visually impressive cases of that.

The question of how to turn these loose inklings into actionable, falsifiable, reproducible science- rather than Aristotelian armchairing - is a hard one.

GuiA··on Avoiding the Global Lobotomy
What resonates with you as a reader is a pure function of what you’ve read in the past though. There’s an argument for trying to stick with movies/books/articles/etc you find difficult precisely to keep the mental torpor described at bay.
GuiA··on Why I don’t usually meet startups in person (2019)
This insight is somewhat echoed in the post itself:

"At the end of the day, doing VC right is actually much more about portfolio construction and modeling than picking."

GuiA··on Words that don't translate into English
From an epistemological point of view, the word "cat" is as untranslatable as the word "sobremesa". That's the absurd part that gets people in arguments on the internet.

In practice, we get by mostly fine (partly because, as you point out, we have footnotes).

GuiA··on Words that don't translate into English
It’s an absurd argument. Either everything is translatable because language allows for any arbitrarily complex construct that lets you circumlocute your way around, or nothing is translatable because everything is steeped in a unique cultural context which you either are a part of or aren’t.

What OP is ranting about is websites glorifying certain words as “untranslatable”, imbuing them with esoteric cultural meaning. As a polyglot and linguistics enthusiast it frustrates me too but we all have to come to terms with people being wrong on the internet some day.

GuiA··on Germany, France launch Gaia-X platform in bid for ‘tech sovereignty’
There has been no better example of this mindset recently than the development of the StopCovid app. It makes no sense on a number of levels, but there are so many government officials pushing it in the name of “la souveraineté de l’État sur la santé”.
GuiA··on Kerbal Space Program 2 release disrupted by corporate strife
"Poaching" is terminology used by recruiters/executives precisely to control the narrative, and justify the kind of employee-hostile decisions that OP is referring to.

It makes sense to reconsider the use of that word given that employers competing on wages and benefits does benefit the employees.

GuiA··on Designing UI for VR Hand Tracking Applications
Kinect offered good full body skeletal tracking. Saying that it could “only recognize dancing” is objectively wrong. And even if that was the issue, look at eg Magic Leap, which had excellent finger tracking. What compelling things were built for it?

The issue is that “gestures” are not a binary thing that you do or not; they live on a continuum. What is waving vs raising your hand to swat a fly? Categorizing these “gestures” in a meaningful way and layering effective gameplay on top of it is the challenge, that pretty much no one solved despite the huge incentives.

Gestures on two-dimensional multitouch screens are not what we’re talking about here (and even then, you can’t expect people to remember much more beyond the 5/6 core ones).

GuiA··on Designing UI for VR Hand Tracking Applications
Beat Saber is a great example - it asks you to do something tiring, but it’s super fun and you have immediate feedback so the effort is worth it.

Games can ask players to do almost anything as long as they’re having fun in return - but that means that the more outlandish things you ask them to do, the more fun they must have.

GuiA··on Designing UI for VR Hand Tracking Applications
That’s actually a very neat line of thinking! If you could model it in terms of gait (slow and heavy vs light and limber) rather than specific gestures, it could make for a compelling system.
GuiA··on Designing UI for VR Hand Tracking Applications
The examples you mention work well because there is a real world affordance (the wheel, the act of throwing) that the gesture maps to. I agree that rotating a wheel gesturally makes more sense as an interaction in VR than the same action does with a mouse pointer.

The grenade example is a good one, because throwing/flicking doesn't require much feedback, unlike say rotation or fine grained manipulation. Of course the interaction would feel nicer if you could feel the weight of what you're throwing - the physics of throwing objects always feels kind of off in VR games - but it still works well enough. Note that many games did this with the Wiimote, and there is nothing about that interaction that is singular to VR.

However, the moment you lose that affordance based in a real world object, and ask your user/player to make gestures in mid air based on recollection, things really do start to fall apart. There is a host of HCI literature/projects around this - e.g. check out papers/demos from the Kinect era. An RPG game like the one you describe could be made with Kinect, and I vaguely recall a few in development - but Kinect demonstrated well that the only kind of gestural interaction that works in long term sessions is dancing.

Btw, this is why if you go to e.g. the VR center in Tokyo, almost every booth has physical props for you to hold/grip/sit on while you're fishing/golfing/shooting a gun/riding a bike in VR.

GuiA··on Designing UI for VR Hand Tracking Applications
Step 1: Make an amazing game with gestures

Step 2: ???

Step 3: Profit!

Joke aside, such game mechanics, albeit with cursor gesturing rather than hand gesturing, have been tried many times before. See Arx Fatalis, Black & White, etc. Jonathan Blow has a pre-Braid prototype about that as well that he shows in some detail in a talk he gave.

The reality is that sure, it sounds cool when you describe it like that, but there are many design issues to contend with:

- how does the player remember all these obscure symbols ?

- how do you deal with the frustration when a symbol isn't recognized? When it's confused by the system with another symbol?

Etc. On top of that, there is the fact that drawing squiggles to cast spells is not a game mechanic that is inherently extremely fun. Why are people going to the bother of doing that vs pressing a button?

It's all a lot of work to make it make sense, and there is little reason to believe that gesturing with your hands instead of your mouse would solve some of the more fundamental problems.

GuiA··on Microsoft now credits maker of AppGet but offers no apology
Oh wow, what is even the point of this blog post? It boils down to:

- we released a thing

- yes we spent time courting the guy who made a version of the thing that ours looks suspiciously like, turns out he’s really good

- well yes our thing has a lot of features taken from the other thing!

- we’re excited for the future!! Maybe that guy can even help us out since he loves open source so much hahaha

Tone deaf at best, implied fuck you at worst.

GuiA··on How many people did it take to build the Great Pyramid?
Totally agree with you, with the one caveat that Youtube is not operated with long term accessibility in mind. Videos routinely are removed by their creator, or get taken down for silly reasons. And one day Youtube will disappear as well.

Archive the channels you care about - they might otherwise be impossible to find in a few decades, or a few years. Youtube-dl is one of my favorite pieces of software.

Digital artefacts could be, paradoxically, less durable going in the future - if you write and publish a physical book, it might get forgotten in a library somewhere and rediscovered 200 years after you die.

If you publish an ebook on your website and die and no one cares, the probability of anyone discovering it by happenstance 200 years later goes down to 0.
