In Germany, selling goods for less then the one bought them for can be illegal if its used to push competition out on a large scale.


I played with this extensively on hobby projects (music visualizer Wayland widget for example) and I like the idea. I like coming up with cool stuff and solutions. The problem is I'm just not disciplined enough, it makes me lazy. The longer I uses it, the less code I read myself and just fire quick /implement loops and go do something else, thinking it should be straight forward. As other have pointed out, AI still needs a lot of hand holding and there are a lot of necessary decisions to make that one usually only realizes while actually building it.


That looks awesome! Do you have any metrics on storage space and query/insert performance for large amounts of data? Building something that has couple of million rows.


We used to do that with device that where in difficult to reach places with harsh uptime requirement! Think industrial routers and protocol converters. I think it pays for itself very quickly. Sending someone for such a device can get expensive.


Only half a data point: I played around with it for a private project. It works but the documentation is far from good enough for production. I was even considering getting the book, but it's not out yet. In my humble opinion, normal documentation should be enough to understand a framework, otherwise you can't expect anyone beyond hobbyist and enthusiast to pick it up. "Break out" is definitively part of the design goals, so I always felt like they put a hatch.


When I was first getting started with Ash I also found the documentation to be frustrating at times. It's less of an issue for me now that I'm more familiar with it. I asked a lot of questions in the discord and found them to be super responsive.

Also, the book is out now.


I wouldn't let the fact that the book is in beta dissuade you from getting it. It's mostly feature complete and is a _fantastic_ resource - it really helped get Ash to click for me, and I've found it a joy to work with after getting that initial ah-ha moment.

I know the Ash team is aware of the documentation challenge, and they are working on it. I feel like the book is an answer to that, and hopefully a lot of the greatness of the book is able to make its way back to the docs.


With the caveat that I’m still learning elixir+ash and just building a small private project, I’ve bought the beta book and it really helped get my head around the concepts even though it’s not finished. I’d recommend it, it’s even on sale at pragprog this week.

Ash itself is fantastic so far. I haven’t worked with anything so productive before. Loving it.


There seems to be the notion in a lot of comments that Stoicism is about acting against one's nature or surpressing ones emotions.

For me, on the other hand, it was very freeing to encounter Stoicism, because I felt like it was okay that I didn't feel or react as strongly as people around me expected me to.


An interesting side effect of that is one can use the grid frequency to coordinate emergency power response - individual nodes (batteries, peaker plants, etc.) can react directly to the frequency measurement with generation or load, thus stabilizing the grid. Too much energy is equally an issue. Usually it's called fast frequency response these days.


Good point... oversupply lightens the load on the generator meaning not as much angular momentum is converted to magnetic flux then to an electric field. Unopposed the torque is able to increase the rotor's speed which directly determines grid frequency.

My grid tie solar system does exactly what you say. It monitors the frequency of grid power and matches it dynamically. There are defined parameters for how out of spec it can get and for how long. I don't recall the exact numbers but imagine 0.2Hz for 100ms, 0.5Hz for 1ms, 1Hz for 500ns. Same thing for voltage though that allows a much wider range.

In CA all grid tie solar also requires communication with the utility (through the manufacturer) with a backup connection source (Internet and LTE in my case). This is so if the grid is nearing capacity or going unstable the utility can command the inverters to allow a wider band of voltage and frequency. The last thing the grid needs in an unstable scenario is everyone's solar panels tripping off at the same time.

Technically the utility can also command the panels to stop production if there is an excess supply but they are limited in how long and how often they can do that.

Fun fact: The interconnect operators used to keep track of the average frequency over time and would run the grid slightly fast or slow to ensure the grid averaged 60Hz over time. This allowed clocks and such to maintain time by relying on the grid. That is no longer the case though. I think they still roughly aim for a 60Hz average but if they're behind by 0.01Hz over the past week they no longer run the grid at 60.05Hz for a while to "catch up".

Fun fact number 2 I just learned recently: Southern California used to be on 50Hz! That's right, the USA had split cycle just like Japan. Most of the country on 60Hz, SoCal on 50Hz. Right after WW2 they made the switch apparently. I guess a lot of stuff was dual frequency capable at the time but the utility provided assistance where required.

Fun fact number 3: Ever wonder why we have 110/220 or 115/230 or 120/240? Because every local utility picked their own standard: 110 (from Edison's DC system carried over into AC world), 115, or 120. It was not until relatively recently that we really standardized on 120/240 (+/- 5% which is 114 - 126 but with brief excursions allowed). That's why some old appliances might say 110 or 115 on them.

Fun fact number 4: 120/240 is a backwards compatibility hack. It was too late to change to 240 and 120 is (for physical reasons) better for electric lighting applications (thicker less fragile filament for same light output). How to solve this? Change your MV-LV transformers to 240 but center tap them. Instead of Line-Neutral you provide customers Line 1 - Neutral - Line 2. Connections across L1/L2 give you 240 volts, connections across L1-N or L2-N give you 120 volts! Everyone's happy! There is a NEMA plug standard for low-amp 240V. It has both blades horizontal (looks like the unimpressed smiley face). I wish it were more popular in kitchens for boiling water and such.


Could you elaborate on that? How come it requires being an insider? What constitutes an insider?


Someone who does things not because he read about them on the Internet, but because they were invented or co-invented, or owned by people he went to school with, or family connections. When "system" is not something you fight with, but it's YOU and people who are your family or treat you as a family. Elizabeth Holmes is a prime example but only because she was caught.
