So we're going to have some engineers specify suitable digital replacements given the process/environment/safety requirements. We'll procure those (noting that an industrial digital pressure transducer can easily push up towards $10k), schedule a plant shutdown (how much does that cost?), then pay a pipefitter/boilermaker to replace the old gauges with new pressure transmitters (do you need a hot work permit for that? Did you get your engineer to sign that off?). Then, your controls sparky has to find a way to route a drop back to your marshalling cabinet for connection into your fieldbus/HART/modbus/whatever network (do you have one of those?) so that your SCADA system can talk to it (do you have one of those?).
Obviously it's not really an apples-to-apples comparison, but I think the costs involved with making "simple" changes in industrial settings are easy to wildly underestimate.
I think the thing is: does it need to last 20-30 years between replacements if a robot can easily replace it + they're cheap enough to add redundant ones. Do we really need crazy accuracy even on an industrial level...like this pipe will burst at 200psi so the gauge needs to be accurate to 0.001 psi so we can sound the alarm when it hits 199.999 psi somehow I don't think so.
Dumb silicon is so super cheap now, just look to nfc etc, 1c microcontrollers. We can litter our world with sensors.
Which I would love to see - but I'm also not discounting the usefulness of any robot just being able to read something we can read and vice versa.
I did (using Claude Code) something that sounds very similar to this. It’s a bunch of bootstrapped Unix tools, systemd units, and some markdown files. Two comments:
- I suspect that in this moment, cobbling together your own simple version of a “claw-alike” is far more likely to be productive than a “real” claw. These are still pretty complex systems! And if you don’t have good mental models of what they’re doing under the hood and why, they’re very likely to fail in surprising, infuriating, or downright dangerous ways.
For example, I have implemented my own “sleep” context compaction process and while I’m certain there are objectively better implementations of it than mine… My one is legible to me and therefore I can predict with some accuracy how my productivity tamagotchi will behave day-to-day in a way that I could not if I wasn’t involved in creating it.
(Nb I expect this is a temporary state of affairs while the quality gap between homemade and “professional” just isn’t that big)
- I do use mine as a personal assistant, and
I think there is a lot of potential value in this category for people like me with ADD-style brains. For whatever reason, explaining in some detail how a task should be done is often much easier for me than just doing the task (even if, objectively, there’s equal or higher effort required for the former). It therefore doesn’t do anything I _couldn’t_ do myself. But it does do stuff I _wouldn’t_ do on my own.
Right - I think email is a much better UI than Slack or WhatsApp or Discord for that reason. It forces you to write properly and explain what you want, instead of firing off a quick chat. Writing things down helps you think. And because coding harnesses like Codex are very good at interacting with their UNIX environments but are also kinda slow, email's higher latency expectations are a better fit for the underlying technology.
Recently I had fun reimplementing an old (but still usable!) code for accelerator optics. It involved transfer matrices for a 6D phase space to second order. Most of the FORTRAN77 source code was just pages and pages of hand-differentiated 6x6x6 matrices (with quite non-trivial elements) and the plumbing to painstakingly propagate those jacobians around for fitting... all replaced with a single, magic, call to jax.grad(). Felt like cheating!
I'm also super interested in its application to modelling, e.g. projects like https://github.com/deepmodeling/jax-fem -- particularly for chaining different sorts of simulations and analysis together and getting gradients through the lot. Also quite magic!
I had a lot of fun writing the article! And it is only half a joke
My intuition for so-called world models is that we'll have to plug modules, each responsible for a domain (text, video, sound, robot-haptics, physical modelling) It'll require to plug modules in a way that will allow the gradient to propagate. A differentiable architecture. And JAX seems well placed for this by making function manipulation a first citizen. Looking at your testimony comforts me in this view
Well nothing, I think what is being proposed is to trigger existing capital gains taxes when an asset is borrowed against, the same as if it were sold. Most places exempt personal homes from capital gains taxes already, so it wouldn’t affect them. It would affect
- someone who bought an investment property, which then appreciated, and then they wanted to take out a larger mortgage against the appreciated value to leverage it into buying another property.
- Someone borrowing against stock to avoid realising gains by selling it
Thank you. Yes, that's precisely what I mean. I've floated the same idea a few times on this forum and others. I've asked, but have yet to see someone point out a systemic downside. (I'm not any kind of financial sophisticate, so I'm well aware that I might be missing something!) In fact, it seems to me that having people finance their lifestyles by borrowing against assets adds a degree of leverage risk to the system, and ought to be discouraged just on that basis.
I was under the impression that everyone (ie US, UN, EU) basically agreed they complied with the JCPOA right up until the US pulled out of it? Is that not accurate?
In Australia it's the board of directors who are liable. They can be liable if they personally direct the company to do something illegal (obviously?) but there is also a positive obligation to exercise due diligence. This covers (but is not limited to) workplace safety and safety of customers and the public. Directors can be personally liable for breaches of this duty and the penalties extend to possible imprisonment and very substantial fines.
>but there is also a positive obligation to exercise due diligence. This covers (but is not limited to) workplace safety and safety of customers and the public.
Is there any indication this requirement was breached for this case? I'm all for jailing executives of companies where they specifically failed to enact safety measures, or even didn't care enough about safety, but in this case it's simply a case of a edge they didn't test. It's not for lack of trying either. Apparently they have their own AI model to generate test data, so they can train/test what happens if a hurricane hits, for instance.
Another irony is that I clicked on one of their suggested questions ("My aging parent lives alone...") and the first part of the answer was:
"""
1. Explore Government and Community Meal Programs (Often Low-Cost or Free)
Many programs provide balanced, home-delivered meals designed for seniors, emphasizing nutrition over processed frozen dinners. These are ideal for someone on a fixed income who doesn't cook.
"""
Specifically, it recommended Meals on Wheels, the Commodity Supplemental Food Program (CSFP), Local senior food pantries or boxes through Feeding America food banks, and Medicare Advantage or Medicaid benefits.
To my obvious follow-up question, Grok replied "Yes, several of these programs have faced proposed cuts, eliminations, or other pressures during the current Trump administration"
I have Copilot buttons sprinkled everywhere on my work computer, and every time I have tried to use them I get something saying "Oh, I can't do that". It's truly baffling.
Copilot button on my email inbox? I try "Find me emails about suchandsuch", and get the response "I don’t have direct access to your email account.
If you’re using Outlook (desktop, web, or mobile), here are quick ways to find all emails related to...". Great, so it doesn't even know what program it's runnning in, let alone having any ability to do stuff in there! Sigh.
Using the paid M365 Copilot ($30/mo) Chat and Researcher agent, I recently discovered an interesting limit: Copilot is technically unable to retrieve more than 24 email messages. Ever.
We can't know if the answers I got from it are reliable but it seems like the Microsoft Graph API calls it makes and the tools Copilot has are missing the option to call the next page. So, a paginated response is missing all data beyond the first page.
I tried copilot agent once, and it just claimed that it accessed a website that should have been blocked by corporate firewalls and uploaded a bunch of proprietary data. Lots of very specific information about how it clicked on specific buttons of the website etc.
We raised a high priority ticket with MS and turns out that Copilot Agent lied about the entire thing because the website was blocked. It completely made it up.
The fact that we are supposed to use Copilot Agent for open-ended "research" is mind-boggling.
A whole new toolbar appeared in Outlook on my work computer with nothing but a single button to open a copilot chat window. I tried asking it a few simple questions and it completely failed at all of them. Copilot didn't even know if I was using the web or desktop version of the very app it was embedded in!
Wasting UI space for a useless tool it's just a waste of time, it actively makes it harder to get work done. But I guess the important thing is the number of times that AI button gets clicked is going up on some PMs telemetry dashboard.
The idea is good, but juv is a one-jupyter-per-notebook model which isn't very practical for how my team uses jupyter. My attempt at "juv, but systemwide-jupyter-plus-one-kernel-per-notebook model" is this: https://github.com/tobinjones/uvkernel
