<p>I've only been playing with it recently ... I have mine scraping for SF city meetings that I can attend and public comment to advocate for more housing etc (<a href="https://github.com/sgillen/sf-civic-digest" rel="nofollow">https://github.com/sgillen/sf-civic-digest</a>).<p>It also have mine automatically grabs a spot at my gym when spots are released because I always forget.<p>I'm just playing with it, it's been fun! It's all on a VM in the cloud and I assume it could get pwned at any time but the blast radius would be small.</p>

<p>I was frustrated not knowing where decisions that affect me were being made, or how my city government actually works. Why has 400 Divisadero been an abandoned car wash for years? Who decides what art to put in Golden Gate Park? I didn't know, but I wanted to, and I wanted to move the needle on issues I care about. I wanted to show up and advocate for more housing.<p>So to help with that I built this OpenClaw skill, it pulls from 22 government data sources and synthesizes them according to my own interests. It has allowed me to understand better how my local government actually works, and now gives me a weekly update on upcoming town halls, trash pickups, and other events I might want to attend.<p>I'm relatively new to the world of civics, discussions and contributions are more than welcome.</p>

<p>I use it all the time now, switching between claude code, codex, and cursor. I prefer CC and codex for now but everyone is copying everyone else's homework.<p>I do a lot of green field research adjacent work, or work directly with messy code from our researchers. It's been excellent at building small tools from scratch, and for essentially brute forcing undocumented code. I can give it a prompt like "Here is this code we got from research, the docs are 3 months out of date and don't work, keep trying things until you manage to get $THING running".<p>Even for more production and engineering related tasks I'm finding it speeds up velocity. But my engineering is still closer to greenfield than a lot of people here.<p>I do however feel less connected to the code, even when reviewing thoroughly, I feel like I internalize things at a high level, rather than knowing every implementation detail off the dome.<p>The other downside is I get bigger and more frequent code review requests from colleagues. No on is just handing me straight up slop (yet...)</p>

<p>To be fair to the agent...<p>I think there is some behind the scenes prompting from claude code (or open code, whichever is being used here) for plan vs build mode, you can even see the agent reference that in its thought trace. Basically I think the system is saying "if in plan mode, continue planning and asking questions, when in build mode, start implementing the plan" and it looks to me(?) like the user switched from plan to build mode and then sent "no".<p>From our perspective it's very funny, from the agents perspective maybe it's confusing. To me this seems more like a harness problem than a model problem.</p>

<p>Can you say more about the nav stack? I thought nav2 was considered one of the better more mature packages in ROS2, but it's not my area of expertise.<p>| As robotics moves toward end-to-end AI systems, stuff needs to stay on GPU memory, not shuttled back and forth across processes through a networking stack.<p>NVIDIA actually is addressing this with NITROS: <a href="https://nvidia-isaac-ros.github.io/concepts/nitros/index.html" rel="nofollow">https://nvidia-isaac-ros.github.io/concepts/nitros/index.htm...</a><p>And ROS native buffers: <a href="https://discourse.openrobotics.org/t/update-on-ros-native-buffers/51771" rel="nofollow">https://discourse.openrobotics.org/t/update-on-ros-native-bu...</a></p>

<p>Not sure if I agree with the christian references being incidental ... the first book is literally a retelling of the The Canterbury Tales, all the characters are on a pilgrimage. there are a bunch of religious groups with at least one being central to the story, there are cross shaped parasites that grant eternal life.<p>I still think you can enjoy it without caring much about religion.</p>

<p>This is very interesting because I see a lot of AI detractors point to the original study as proof that AI is overhyped and nothing to worry about. In this new study the findings are essentially reversed (20% slowdown to 20% speedup).</p>

<p>The study was designed to have devs who are comfortable with AI perform 50% of tasks with AI and 50% without. So the problem is the population of "Developers who use AI regularly but are willing to do tasks without AI" is shrinking.<p>>> Are they worried that by splitting devs into groups of AI experience they might be measuring some confounder that causes people to choose AI / not AI in their careers?<p>The developer sample size was small (16 people in the original study) and the task sample size is larger (~250 tasks). I think the worry is variance in developer productivity would totally wash out any signal.</p>

<p>In addition to what the other responses said:<p>1. Share a cohesive and inspiring vision for the project.<p>2. Understand your skills, strengths/weaknesses etc and try to give you work that challenges you / help you grow / are interesting.<p>I think these are rare and can be hard to do (I'm now trying to do it myself!), but when it happens it's very motivating.</p>

<p>You are correct, NTP prefers to jump first (if needed) and then slew afterwards (which is exactly what we want!), although it can jump again if the offset is too large.<p>In our case the jumps where because we also have PTP disciplining the same system clock, when you have both PTP and NTP fighting over the same clock, you will see jumping with the default settings.<p>For us it was easier to just do a one time NTP sync at the beginning/boot, and then sync the robots local network with only PTP afterwards.</p>

<p>We don't use NTP, but for robotics, stereo camera synchronization we often want the two frames to be within ~10us of eachother. For sensor fusion we then also need a lidar on PTP time to be translated to the same clock domain as cameras, for which we also need <~10us.<p>We actually disable NTP entirely (run it once per day or at boot) to avoid clocks jumping while recording data.</p>

<p>Late to the party here, but you should definitely be using pytorch 25.09 (or whatever is latest when you go to check) rather than 24.10. That's a year old pytorch on new hardware, I suspect a lot of these bugs have been fixed.</p>
