Interesting work. Thanks for open sourcing. It would be nice if the "run" script has a bit of documentation, and maybe an "examples" folder the the run script can work with. From what I can see it seems to search the parent directory? I would want for example `./run <dir_with_tests>` to run all tests my specified project repo.

This too is one of the most interesting integration to me. Allows for getting logical deduction from an external source (e.g. wolfram alpha), which can be interacted with via the natural language interface. (e.g. https://content.wolfram.com/uploads/sites/43/2023/03/sw03242...)

For those interested the original Stephen Wolfram post:

It seems they link to a discussion page [1], which references this document (I can't find a published version):

    Computer text line lengths affect reading and learning 
    Peter Orton
    https://cdn.tc-library.org/Edlab/eye-tracking%20article.pdf

But it seems that Peter Orton has published quite a few works in this area [2], [3]. Specifically [3] seems to note that with a less wide text column width readers are not statistically significant faster (but are a bit), but do see that for difficult reading content, the shorter width requires less re-reading then a wider one along with significantly better retention of the contents of the document.

I think this isn't the case for many open source projects I use. The reason I'm drawn to OSS is for the ability to be able to fix it down the line by myself. This also allows me to possibly contribute back those improvements so others can leverage them.

I recently saw this great plugin for OBS which uses Google Speech Recognition api to stream captions to twitch along with your video. Not sure about the quality or delay.

This had the cross origin issue for me. After combining with an above post that uses GM.addElement this looks really nice. Grayscale is the way to go to prevent the site from being more addictive than it needs to be.

It would really help if the author had a list of "features" on the github project. It is a bit difficult to figure out what exact functionality the project supports.

I agree with this. What happens when I got to my bank with this extension? I would rather have either what another commenter suggested (a bookmark) or be able to see the source. I assume they use the "activeTab" permission to give temporary access to the current tab?

From a quick look, it seems to just request access to all pages? I am not sure if chrome really has a elegant way to handle per-website requests (as compared to per-tab).

My thought is why don't the authors use github pages to host their static site with their links to a dedicated server with an unmetered link since their whole project is CC0. Downloading assets doesn't need to be low latency, thus I don't think the caching spatially near the user is important. Having a user login for patreon is something that would be missing and require some more thought I admit.

I think quite a lot of other people have mentioned in the thread that they are getting a lot of other "benefits" from using multiple services, but I don't see how these help solve the problem of data delivery besides taking advantage of the Cloudflare + Backblaze alliance which is $31 if their main website is a static one.

This is a great write up and was really interesting to read. My question is why would the proposed changes are not already included upstream? Isn't a faster boot what everybody wants?

The actual documentation website presents the problem far better then this homepage [1]. I recommend that you hire a web designer for the landing page as this website comes off as a scam at face value currently. The docs seem to have a lot of interesting details that I never knew about the space, thanks for sharing.

My understanding is is that group invariance is just another perspective to look at the original non-linear system transformations as compared to the more traditional "on-manifold".

Really it seems like an easier way to derive a system which the observable properties of the system are well defined as compared to worrying about ensuring observability (and unobservability) properties hold through the non-linear linearization process.

There are quite a few groups that use "invariant filters" in robotics (eg [1]), but I always wonder if this could not be addressed through more traditional means (i.e. designing a better state representations or correcting gains in unobservable directions).

Roumeliotis is referring to Stergios [2] or another scholar? Could you provide full names?

Observability is interested in asking if you, as an external observer, are given a set of inputs and measurements are you able to recover the initial state of the system?

While identiability typically is just a person running an experiment and saying "hey look these state values are unable to be recovered / estimated when I ran the algorithm". This is why I never understood why this analysis was very helpful as it isn't very useful outside of the specific experiment / motion / inputs used.

For example from [1] has these reasonably straightforward definitions.

  Observability is a structural property of a control system dened as the possibility to deduce the state of the system from observing its input-output behaviour

  Identiability is the possibility to identify the parameters of a control system from its input-output behaviour.

  Parameter identiability is a special case of the observability problem.

I think from the original DARPA challenges most researchers knew that while self driving is possible or more correctly "a promising direction", but its application to the realworld and its robustness was a far larger barrier back then.

We have the advantage of retrospect when looking at these claims which now may seem more possible then before due to our better understanding of the difficulties and technologies to address them.

I think many people confuse their excitement for the promise of having self driving cars and the actual technical and political barriers that still need to be addressed to bring this to reality (ranging from robustness, infinite number of edge cases, perception, insurance, or public policies).

While taking two sequential images from the same camera in can provide this depth information also. But simple use of stereo cameras can solve a magnitude of problems (standing still and low parallax motions). Traditional stereo and even machine-learning based methods have have great success and accuracy for many years and could easily be an alternative to LIDAR also.

I really don't know why this isn't leveraged more (maybe it is and I am unaware?).
