    I think you've just lowered the risk of a bad hire for the company, which might allow them to "take a chance" on candidates they might otherwise pass on.

    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 ( https://github.com/sgi…

    Show HN: An agent skill that tracks SF city hearings, permits, lobbying etc.

    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? …

    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. I do a lot of green fie…

    To be fair to the agent... 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 …

    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. | As robotics moves toward en…

    In my experience a lot of tech companies, at least in the Bay Area, have all copied this system.

    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. …

    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 a…

    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 b…

    Very cool! shameless self promotion but check out greenwave-monitor[1] for the 'Diagnostics TUI'. I'll get it into the buildfarm soon. [1] https://github.com/NVIDIA-ISAAC-ROS/green…

    I think a lot of people assume they will become highly paid Agent orchestrators or some such. I don't think anyone really knows where things are heading.

    Who is buying the old cards? They can't be used for gaming, if there was money to be made I think they would be doing it.

    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. In our case…

    MIPI CSI, with USB cameras I usually am getting jitter in the millisecond range.

    Comment #46357884

    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 t…

    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, …

    It has a unified memory architecture, so the 128G is shared directly between CPU and GPU. Though it's slower than dGPU VRAM.

    Also interesting in the example shared that 03 thought for 5 seconds for the female case and 46 seconds for the male case. Wish we had access to the chain of thought.

    Robotics is sorely lacking front end devs and UI/UX guys. Most companies won’t hire any until they are already pretty established, but they might hire some. You can check out compa…

    I still think there is value in chats and retaining context. But there is also value in starting clean when necessary. Giving users control and teaching people how to use it is the…

    Compressing existing models is exactly what we are talking about here.
