If it's got bits, I'm up for it. I started computing in the 80's, in the 8bit era and just never quit!

Main focus: Embedded, small scale systems

I have done a lot with CAD, PLM, and enterprise level engineering software, and have more than a passing interest in UX.

Additive Manufacturing is cool, and what I do now. Polymer printing and soon DED metal!

Actually, a fair number of us will see the font change.

People are more aware of typography than you may realize.

...maybe you do!

In which case, this makes real sense: "[almost] nobody will care."

I wouldn't, but I sure would note the font change.

Bullshit, horseshit, cows hot.

The whole win 11 thing is embarrassing.

They are this far in, pushing features nobody asked for and is there any wonder the numbers blow chunks?

None.

Some keyboard apps will input those shortcut combos. Many work on phones. I found out when using a Bluetooth keyboard one day for some emergency doxument create when I got stuck with both a deadline and a dead laptop.
ddingus··on NoLongerEvil-Thermostat – Nest Generation 1 and 2 Firmware
Yeah, I figured as much. Sad day :(

For what it was worth, I really enjoyed helping everyone ramp up on NX. At that time in my career, I was ramping many similar groups up and many came from Apple and were experiencing sticker shock! (They bought the very best and it was not at all cheap!)

We talked about that and those in charge on my end were not at all happy with me showing people how geometry that normally requires a higher tier license to create, can be created with the base tier license, lol. (Mere mortals need that info because having the more expensive tool is not always on the table.)

Anyhow, stay cool. Maybe it will be different one day.

Please tell the others as you may encounter them, "That NX guy from PDX says, "Hi." You all may not know it, but I learned a ton from you guys. It was in the questions you asked and the processes you set up. I am applying some of that to my own projects today. So, thanks! ( way late! )

ddingus··on NoLongerEvil-Thermostat – Nest Generation 1 and 2 Firmware
I really hope this project succeeds. In some small ways I was involved with Gen 1 and Gen 2 and the teams that built those products really cared. I doubt they would have said turn them off.

I am speculating here.

The reason for it being a two level device at present is likely due to it being mostly research and not so much engineering.

They say their next chip will deliver grey scale and many more signal points.

My guess on color is one or more of the following is true:

[0]The color info is normally sent via the color sensitive cells now damaged and we have yet to understand how that signal enters the nerves we can send a signal to.

[1]It may be that we need a far smaller, more precise signal point to achieve color. Current tech stimulates many nerve endings. This was the basis for my interpolation comment above. Basically, each pixel stimulates an area of the damaged retina which contains a great many possible signal points if it were possible to stimulate them individually. Because so many are stimulated all at once, the subject perceives white phosphines rather than colored ones.

An analogy would be the colors on a CRT. A broadband beam would light them all up, yielding monochrome vision. A narrow beam can light up a few or just one, yielding color.

One thing I just realized writing this is our blue sensor cells are scattered about, not well clustered like the green and red ones are.

Maybe current users see a bit of color at the very extent of the artificial visual field due to a failure to hit the necessary blue cells...

[2] It may be some sort of pulse is needed to encode colors. And perhaps the current signaling is continuous.

Hopefully, we get an answer from the team.

The lag would be in signal processing external to the user.

Interpolation would be more transparent, much like it is for you right now. There are no phosphors in tubes in any of this.

I made no such "snow crash" assumption.

Users of devices like this have described their experiences and those are not generally big square pixels.

Think of those more like points the brain can do something with.

The chip stimulates the remaining neuro-signal entities present in the damaged retina. I doubt there is a 1:1 relationship between those and the signaling points on the chip.

When the company can do better than on/off bright/contrast, the overall experience should improve dramatically. There will be more signal points (1024 ish?) and those having variable output levels will give the users visual cortex a whole lot more to work with.

About the only analogous thing I can come up with is cochlear implants. Those have a number of signal points that seems a lot smaller in number than expected. That was certainly my take. The more of those there are, the more concurrent sounds can be differentiated. A greater sense of timbre, in other words, becomes possible.

ddingus··on How the cochlea computes (2024)
Thank you! This is an excellent work. Much appreciated
ddingus··on Eye prosthesis is the first to restore sight lost to macular degeneration
378 pixels, 1bpp

The Phosphenes[0] patients sense will depend on what is left of the retina. People using earlier systems reported some interpolation happened. Maybe that is true of this device too.

[0] - that is the name for the image the brain manifests in response to signals received by the visual cortex. Most of us experience them when we close our eyes and rub them, or maybe just see stuff that is unreal.

ddingus··on Why can't transformers learn multiplication?
Achieving agi is not a requirement to working well.
ddingus··on Why can't transformers learn multiplication?
I am not sure it needs to scale.
ddingus··on Why can't transformers learn multiplication?
Yes, and unlike the LLM they can iterate on a problem.

When I multiply, I take it in chunks.

Put the LLM into a loop, instruct it to keep track of where it is and have it solve a digit at a time.

I bet it does just fine. See my other comment as to why I think that is.

ddingus··on Why can't transformers learn multiplication?
A while back I saw a post where people ran a model over and over to accomplish a code base port from one language to another.

In their prompt, they told it to leave itself a note and to accomplish something each time.

Then they put the model in a loop and it worked. In one instance, a model removed itself from the loop by editing a file or some other basic means.

To me, iterative tasks like like multiply and long divide, look an awful lot like the code port experiment.

Putting models into loops so they get more than one bite at the task seems to be a logical progression to improve capability.

It may default to 9600... tons of devices will fall back to that, given no other instruction
ddingus··on Your very own humane interface: Try Jef Raskin's ideas at home
My take on his book is it contains many tools one can use to reason about UX issues effectively. Parts of the book are dated, but that does not seem to take away from otherwise solid user interface discussion.
ddingus··on Nest 1st gen and 2nd gen thermostats no longer supported from Oct 25
This crap is exactly why I do not ever purchase devices like these.

Yeah, I don't have a smart home, but all my old stuff works great and that will continue until after I have left this place.

Maybe I do have a smart home.

ddingus··on We should have the ability to run any code we want on hardware we own
Perhaps. It is a little hard for me to gage.

The non criminal part in all this does carry serious weight with me, and on that basis I agree more with you.

It is harsh. It does not need to be.

ddingus··on We should have the ability to run any code we want on hardware we own
Oh, not lifetime then. Good. Seems quite reasonable. Thanks for the details.
ddingus··on No clicks, no content: The unsustainable future of AI search
They can be excellent, but only in the moment.

The excellent communities I have been a part of can be searched. People can read it and learn. The Discord ones, unless they publish to a wiki or something, just don't exist.

ddingus··on We should have the ability to run any code we want on hardware we own
Painful!

How does one get shut out?

Perhaps a story of his life now could be told to whatever politician may make sense? (I just do not know that for your part of the world)

Seems to me there must be some basic government run thing to manage this. Using corporations has too many problems.

And you may tell me BankID is government! Hope not.

ddingus··on We should have the ability to run any code we want on hardware we own
Give Google and Apple anything they want, in exchange for a reasonable life.
ddingus··on No clicks, no content: The unsustainable future of AI search
I hate that about Discord. It is a fun comms application, but it is severely lacking as a community.

Once, before I realized this, I recommended users of a forum use Discord. The impact was severe and fortunately brief. We all realized we would not be leaving the usual, often high value info for others, and ourselves to benefit from in the future.

We unwound that mess and now carry on in the usual way.

Discord has carved out a huge chunk of discussion people will wish was available in the future.

It is easier that way. Less to manage.

Apparently nobody! I misread. Good grief, subtle problems related to this overall discussion are chronic.

Sorry all. The short comment parent to mine tells a very suggestive story with high brevity. This is similar to Hemingway writing a story in a few words: "For Sale: Baby Shoes."

The hook aspect of these appears similarly suggestive and brief and I thought that intriguing and thought provoking given the overall subject matter.

And that just gave me some reference to the speed this whole tech branch has.

ddingus··on Why do people keep writing about the imaginary compound Cr2Gr2Te6?
The URL is formed using the date, just FYI. :)

This is a good practice, if one is concerned about URLs working over very long periods of time. "Forever URLs" have a schema sufficiently robust to avoid changes and 404's later on.

ddingus··on Why do people keep writing about the imaginary compound Cr2Gr2Te6?
Summary: Because they are not writing!

They are copying data and placing it into documents.

Obviously, these are not the same thing.

This whole discussion is blowing my mind!

When I hit your comment:

1. I thought, "YES! Indeed!"

2. Then, "For Sale: Baby Shoes."

3. The similar feel caused me to do a rethink on all this. We are moving REALLY fast!

Nice comment
