<p>Related: I've been pretty frustrated with cursor that you can't call any APIs directly, and it all has to go through their backend. Along with this, they have essentially refused to fix bugs in their custom API key page for months, forcing you to use their "1st party" tokens.</p>

<p>Here’s the simple reason why this is not the case:<p>If you provide the 6DoF trajectory (+ gripper joints), a lot of robotics (manipulation in particular) is basically solved. The problem is, we don’t have these good trajectories.<p>Sure, joint space is commonly used for learned policies, but cartesian space isn’t uncommon either.<p>IK is really just not a major focus on the learning side of robotics because it’s not the problem. The problem is we don’t know what to do even at the slightly higher level.</p>

<p>The challenge here is not IK. Sure, you don’t need IK if your policy directly operates in joint space but this isn’t the motivation for doing RL.<p>IK to my knowledge is well known in every setting I am aware of.</p>

<p>It’s less reproducible than docker (assuming the pip usage is correct). Docker specifies a lot of OS properties that UV ignores.<p>That being said, UV is great.</p>

<p>I tried out uv a bit ago and dropped it. But about two weeks ago, I switched to it and migrated two projects with no issues.<p>Things like pypi sources per dep are there finally.<p>I still find rough points (as many others pointed out, especially with non sandboxed installs), that are problematic, but on the whole it’s better than Mamba for my use.</p>

<p>Clusters and supercomputers are able to fully control the hardware & OS. environment modules are useful in that setting but do not solve OS differences, not to mention themselves need to be installed/maintained. lots of time developers do not work on your same cluster (say, for any open-source code) and environment differences can be significant.<p>I regularly use large clusters and even there docker/singularity are very helpful at times (very simple example, glibc requirements).<p>When you are talking about well-written code that only requires posix (and nothing beyond) and does not interface with hardware, etc. etc. then virtualization seems crazy.</p>

<p>For a start, any suite that takes >X hours on a single node, especially compounded if you have a large team of developers.<p>> At least as long as you're running your own code on your own hardware<p>Assuming you keep a consistent env/OS across all nodes you will want to run said code. Which can be difficult, even just between two users on a single node.<p>Not to mention the fact that a lot of (most?) code needs to (A) interoperate with other people's code and (B) at least sometimes run on other hardware.</p>

<p>I think it’s just super handy to know where you’ve been. Great to be able to find places (“Oh I loved this Thai place I went to 4 years ago in X city”)<p>Also to be able to find photos in specific locations (if you integrate it with geotagged photos like google does).<p>It’s one of those things I don’t actively care a ton about in the short term but is useful data to have in the long term if it can persist without a lot of effort.<p>Edit: I think form is “irrelevant” as long as it’s well supported and can be useable in different services later on. Same thing with notes imo (and why I use markdown). Has enough features but importantly is and will be well supported.</p>
