We make a system for assisting self-evacuation from tunnels using directional sound effects: https://norphonic.com/products/evacsound/ Most of the userspace work including the planner, fire detection, resource scheduling and distributed execution is done in Common Lisp.

Fascinating. Our Volvo does this for backing up and getting warnings from sensors. It uses the individual speakers from the direction of the issue. Works great.

Earlier quoted context omitted.

I guess I would say that subcontractors are more like hourly workers (who are time tracked meticulously in almost all industries) - not salaried like software engineers, who would deserve the respect and absence of tracking.

Not really, in the housing industry, it is generally job bid instead. The contractor taking longer just means they get paid later and don't get as many jobs done. Also, Unions hate this right?

It's less about tracking how long they're there and more about when they showed up. We do the former because we can, but the GC really wants to know if and when their subs are showing up without having to be on site 24/7 waiting for them.

For example, they can look back through yesterdays events to see that their plumber showed up - and then they'll know they need to go check on the work. The alternative is trying to get the plumber on the phone to figure out if the work had been completed or not - which is difficult in 2023.

There's not a lot of unioned workers in most states for residential construction. But autoworkers, and anything else in manufacturing would be used to the constant monitoring. Commercial construction also typically has fulltime site superintendents, who would do this anyway.

As someone who used to work at an IoT company the consumer space is brutal. Unless you've got something you can sell for 10x BOM, or there's naturally a subscription based model then it's not worth the blood, sweat, and tears.

10x BOM? Why is the bar so high for profitably? There are manufacturing costs, marketing and inventory risk. But still… what am I missing?

The math is this: BOM + cost to acquire a customer + cost to sell the unit Otherwise you don't have a business. Please don't ask me how I know this.

10x is a rule of thumb, YMMV. You just need to make the above inequality evaluate to true. You can (maybe) raise money to deal with the various non-recurring expenses. Oh and you should pay your employees too.

If this were a camera that identified when and for how long a software engineer showed up to the office and notified their employer of "unwanted behavior", how long would it take for that story to end up on the front page of this site and torn apart as invasive and infantilizing?

I think if these got to the point of "worker stared at floor for 7 minutes" it would be invasive. If it tracks when a vehicle shows up to site and leaves. That being said, as someone with digestion issues, tracking bathroom habits is offensive. In short, yes this is invasive. But much like AI, this type of thing isn't going away, there is just going to be more lawsuits about it in the future.

We should make it illegal by law.

We develop huge 32" interactive display touch screens for trade shows and conferences that allow users to interact with apps and websites that a company wants to show. They look amazing and are always a show stopper for booths. They run a custom os based on AOSP which allows companies to use there pre made android app for the display instead of having to build anything custom. We also offer a website module that will display your website in full glory and interactivity.

For more information or to rent a display you can send us an email isaac@bigtopdisplays.com

I come from a traditional full-stack engineering background (web frontend + backend) and recently founded a smart toy company[1], the first product built on ESP32-S3. I took a few weeks for me to get comfortable writing firmware (although there is another more experienced engineer doing the primary work and electrical). I'm really excited for Espressif (the chip maker) to roll out newer versions of their microcontrol…

I have a similar background as you. How are you finding handling the mechanical side of things? I assume your toy is more than a PCB.

We make a camera system for construction sites. Using computer vision, we can identify when and for how long subcontractors show up as well as notify our customers of unwanted behavior on site. https://bedrockwireless.com/ Fun fact, we probably have the best port-o-potty detector in the world.

Looks neat, is your core product the AI for the construction site object detection?

We don't track port-o-potty use, just if they move. Vandalism is at an all time high on construction sites, tipping port-o-johns is a common teenage prank and the GC needs to know if and when this is happening on sites (and hopefully catch the perpetrators).
