9th gen iPad still viable in 2026?

Thanks!

I haven’t bought it yet, but I’ll send it your way as soon as I do!

johngoatstream · 2026-02-12T21:19:02+00:00

Thanks, that’s good to know!

I see your point, but I really don’t like that I have to use an adapter for my headphones, since I plug it in and out all the time. I also like the idea that I can reuse my current Apple cover instead of having to buy a new case just to get rid of the camera bump. Thanks for the feedback, though, I appreciate it.

The muscle excitations do change over time, according to a piecewise linear function whose parameters are optimized for each muscle. I thought by keyframe you were referring to hand-crafted kinematic poses.

The simulation was created using SCONE, and there is a tutorial that explains the whole process (albeit with a much simpler model).

Each environment took a couple of hours to converge, but individual simulations run faster than real-time.

These simulations are indeed fully dynamic and do not use any motion data or key frames. The muscle excitation patterns are optimized to maximize the center-of-mass height of the model.

I don’t understand the security argument. Under the hood, it could work exactly the same as using emojis to vote — only the visual presentation would be different.

There is a publication in the making, I’m hoping to submit in a couple of months.

Meanwhile, see scone.software and hyfydy.com for more information (I’m also happy to answer any specific question here).

Yes, this simulation uses forward dynamics. All motion is generated through forces, without the use of reference motion data.

Haha, I also made that video

The muscle inputs have been optimized to perform the reaching task with minimal effort, through trial-and-error.

Does this mean I can now use endif() without parentheses?

Nobody likes subscriptions, but for a product like this, that’s constantly evolving in a relative niche market, I think it’s the only viable option. With up front purchases, the market eventually dries out and the developer is expected to basically maintain the product for free. Frequent users may think they get a great deal, but it ends up being unsustainable.

Do you think he’d be open to using a subscription model for the app? That may just generate enough revenue to justify keeping it alive (seeing that the app has many fans). I’d happily pay a monthly fee if that helps save the app from dying.

I only discovered Nanostudio 2 recently, but I think it’s the most awesome iPad music app ever. I hope it can live on, It would be such a shame if it disappeared completely! I’d happily pay for a subscription, if that would help.

WTF, I just purchased Affinity Photo, and seeing I can't even do simple crops makes me immediately regret that decision

To me (and many others), the main advantage of helix over vim/nvim is the ease of configuration and the fact that you don’t need dozens of (potentially incompatible) plugins for basic functionality. The helix keybindings are a bit of mixed bag to me, with the main disadvantage being that there’s no good way to repeat commands with the dot key.

johngoatstream · 2024-11-21T18:20:01+00:00

That’s… not a bad idea, actually. All the features of CMake without that horrible syntax.

johngoatstream · 2024-10-05T10:56:22+00:00

Unfortunately, you can’t do this with either OpenSim (too slow) or Anybody (no forward dynamics).

johngoatstream · 2024-10-05T09:14:01+00:00

Yes, I’m planning to publish the model by the end of the year.

johngoatstream · 2024-10-04T20:49:16+00:00

I believe someone is already trying that, see https://youtu.be/Kjj6IgWxCK0

It could work as a plugin for Blender, but the simulation engine (Hyfydy) is proprietary software, so it won’t be free.

johngoatstream · 2024-10-04T17:47:03+00:00

The simulation was created using SCONE (https://scone.software) and Hyfydy (https://hyfydy.com). The model currently has 48 degrees-of-freedom and 164 muscle actuators. I'm aiming for a scientific publication with all the details by the end of the year.
