hoc··on Hand Tracking for Mouse Input (2023)
Tap (tapwithus.com) had a IMU-based solution early on in the current VR hype cycle using a IMU for each finger and some kind of chord-based letter typing system. Was a fancy proof of your geekiness to wear them during VR meetups back then.

I think they have a camera-based wristband version now.

Still doesn't have any room positioning info though, AFAIK.

hoc··on Hand Tracking for Mouse Input
Cool path and write-up. Thank you!

Just because of the use case, and me not having used it in an AR app while wanting to, I'd like to point to doublepoint.com 's totally different but great working approach where they trained a NN to interpret a Samsung Watch's IMU data to detect taps. They also added a mouse mode.

I think Google's OS also allows client BT mode for the device, so I think it can be paired directly as a HID, IIRC.

Not affiliated, but impressed by the funding they received :)

hoc··on A secure embedded operating system for microcontrollers
For that Nordic 52 dongle... the ones I bought early on had locked bootloaders and only allowed apps on top of that, AFAIR, and needed at least some HW debugger connection to remove it.

Is this still necessary, included for TOCK or is not needed at all?

hoc··on Where are the builders?
Why not make your kids do the dishes with some gamification instead of having them play video games and see how it goes.

That builder might just be the wrong suspect in this two-party relationship issue.

Maybe your products need more awe, your attitude needs more respect and you might just give it a try to look at the person and not just see their exploitable potential as a start.

With your kids, reward them with more responsibilty, choice and partial ownership of your household and its direction and decor, and it might actually work out. Share your assets and see what they will be used for by those you see so much potential in.

In a way that is what those interships and simple tinkering allowed when companies were smaller and the industry was less complex. Finding ways to encourage them and supporting their ideas instead of looking for work force for your own projects might just be a real investment in everbody's future.

You might just have to give up the idea that it's now your turn to lead (from that inherited spot).

It just has always been your turn to add value.

Invest your (real) assets.

hoc··on Apple apologizes for iPad 'Crush' ad that 'missed the mark'
Why Microsoft?

Belt holsters in future Apple keynotes just do not seem that impossible anymore.

(Phone holsters, of course.)

hoc··on Decker: A reincarnation of HyperCard with 1-bit graphics
You can increase the zoom factor in Safari's address line, hitting that aA button and then the big A...

That, combined with landscape mode seems to make it usable, at least on the Max models.

hoc··on German public broadcasters open source their streaming platforms
To understand the quality level of their current platforms: they actually manage to recommend the same stream you just watched as the next auto-play entry and even might jump directly into the credits again, giving you a 10 to 20 seconds loop in extreme cases.

While a two-stream recommendation loop is quite common in both systems, the loop above only happened twice for me so far. Still, it might just perfectly highlight the lack of passion and user focus plaguing their current platforms.

So, whatever they come up with in the new and maybe open one... ah, who am I kidding.

hoc··on Fragmented thinking is a bigger threat to flow state than interruptions
Even movies say: Opening invoices and final notices just keeps you from evolving into the hero that you're destined to become.

Bad interpretation: Keeping the flow at any cost might make you drown.

The whole productvity thing seems much more complex situation-wise, and still it boils down to keeping it up.

Everything that nudgingly reminds you of that seems helpful. If it's a person, you even can hate them for it. A little bit at least.

hoc··on The Myth of the Second Chance
Decision tree vs. Turing machine

Variation in overall size, branch angle/length/node distance influence the resulting number of possible steps, as well a the limited run time and state complexity does. This also lets "fail often, fail early" look like that simple approach for a massive wide step zig zag approach to life; only if assuming no life-relevant costs per step, that is.

Still, a state machine with loops allows for second chances in general, while the underlying environment also changes in parallel. So your outlook for the second try might as well be better.

To describe a backwards directed re-play, a decision tree might be a tempting structure. But just because the "truth" is too complex to describe and not visible to you in its entirety anyway.

Don't get discouraged by these kind of undercomplex views on life. There's still lot of environmental problems/limitations to be solved, to make everybody's run a bit smoother and less dependend on their environment, though, even though, or because, all the runs and the environment are basically the same thing.

hoc··on I keep a WTF notebook (2021)
For some this might have a bit of sociopathic creepiness to it which even seems more apparent in that marriage context than it does in the original article of an "deeply" structured coder.

Of course control might be a valid goal, and controlling your need to control might be a good meta step, too, in a professional environment. The issue of the line between caring and controlling just seems not been discussed enough. And not seeing and mentioning that obvious emotional aspect might already make it look a bit weird.

hoc··on Myths about the Anthropocene
Making fire and the wheel considered dangerous, choosing farty animals for our cultivation endeavors stinks while getting down from trees into concrete caves was a bad move. Scaling that up to "everyone"... priceless.

What we once considered pivotal points in our development seems now the source for our declared demise. At least we discovered that via satellites shot into orbit by rockets.

Now, if we accept that as the natural overshooting in a evolutionary jump, we just need to adjust. The undershooting will be painful, the discussion in the next few oscillations annyoing, still, it's the way to go. After all, denial is just a common step in change.

hoc··on Ask HN: What movies changed your perception of reality or life?
Blade Runner, as it was the first one I saw that was about the meaning of memories and beliefs.

I actually liked The 6th Day when it comes to ideas of our "natural" view on identity and ownership of individual assets etc.

Matrix, of course, for its search for reality/truth behind ones inherited perceptions, no matter what consequences (there are more ideas in the movies, though).

hoc··on Experience report: It will never work in theory
First time I heard about the site...

(... was back then, and I was amazed, of course.)

hoc··on Andres Freund and the xz backdoor
With even the NYT on board it should be clear to everyone now that the whole xz thing must be a plot to have that Andres Freund person introduced into government and security circles where he then can finally fulfill that heinous plot. Classic.

Ahh, the voices...

hoc··on Memories are made by breaking DNA – and fixing it
I immediately thought of that too. But also other influences on these reactions might be interesting to look at. From stress levels to metabolic issues including unbalanced supply with nutrients, infections, injuries. How do you remember your last exhausting argument or traumatic experience...

Not sure about the actual mechanisms, but the idea of these kind of influences on individual memory formation is intriguing.

After all, it's hacker news :)

hoc··on The lithium-ion battery may not be the best bet for EVs
There might be other interests, political ideals, economic principles, availability of/access to ressources that might tilt the actual decision making beyond "getting the thing done". Even at additional costs, long before its prime time, channeling research and development budgets in certain directions.

After all the latter part is an important motivation for publishing broader articles and certain studies early.

hoc··on Show HN: OK-Robot: open, modular home robot framework for pick-and-drop anywhere
While I would agree in general, I once slipped on one of those overly steep carved-out kerbs in SF and broke my elbow... I guess if you hit a bad spot you might need a wheelchair afterwards (ok, but it really did hurt!)

So you have to do it right to keep the potential harm as low as possible and not forget about security in the face of rewarding improvements. And watch your step, of course.

Might also be applicable in the context of self-learning household robots and their potential to burn down that house :)

Sleeping much better now with that relaxing clarification for brown noise...

What a great list.

hoc··on Neural Network Diffusion
Hm, so does this actually improve/condense the representation for certain applications or is this some more some kind of global expand and collect in network space?
hoc··on Stop postponing things by embracing the mess
Great. I'll add that to my signaling items options.

Makes me wonder why I see bringing my phone being a safer bet than bringing my hands :)

hoc··on Stop postponing things by embracing the mess
I also suggest to add a physical signal on your typical life accessories like phone or watch.

E.g. swapping or adding a special colored case during productive time to remind you to return to focus on production when you tend to break into "day-dreaming".

Does not make you start the day, but lets you keep going longer (ok, that might sound wrong, but let's keep it for its mnemonic value).

hoc··on I broke IKEA (2023)
That modem comms sound is IKEA's backhacking attempt. Much more advanced than touch tones.

Beware!

hoc··on OpenAI Deal Lets Employees Sell Shares at $86B Valuation
The old industry question is whether it's complex and protected enough (or the separation wanted by the consumer, but that's an old guy's dream) that the owners of the production equipment can't do it on their own.

Azure, AWS, Google are easy candidates, Nvidia might even be proof.

hoc··on Sora: Creating video from text
Everytime OpenAI comes up with an new fascinating gen model it also allows for that bluntly eye-opening perspective on what flood of crappy und unnecessary content we have been gotten accustomed to being thrown at us. Be it blown-up text description and filler talk, to these kind of vodka-selling commercial videos.

It's a nice cleansing benefit that comes with these really extraordinary tech achievement that should not be undervalued (after all it produces basically an endless amount of equally trained producers like the industry did in a - somehow malformed - way before).

Poster frames and commercials thrown at us all the time, consumed by our brains to a degree that we actually see a goal in producing more of them to act like a pro. The inflationary availability that comes with these tools seems a great help to leave some of this behind and draw a clearer line between it and actual content.

That said, Dall-E still produces enough colorful weirdness to not fall into that category at all.
