If you download and install untrusted code extensions, you’re screwed. Not like it’s rocket-science.

What if you end up with a child who likes maths AND crying?

Smart move. Now you know who to blame if Siri tells you to put glue on your pizza.

Got a couple of 50ft, high-speed Ethernet cables delivered today. Spent the whole afternoon moving boxes and furniture so I could hide them from view.

I could have volunteered for this study… but put it off.

A long time ago, I turned a PC in my basement into a web server. No DNS. Just a static IP address. Within 15 minutes, the logs showed it was getting scanned.

SSL encrypts traffic in-transit. You need to set up auth/access control. Even better, stick it behind a Web Application Firewall.

I helped set up many households with kids on Pi-2s and 3s, running Raspbian and Kano. All you needed was a keyboard, mouse, and a monitor. It all worked fine with Scratch, Minecraft, LibreOffice, Web, and email.

At least, until the kids outgrew them.

Super-Intelligence has been achieved.

Arduino is based on the ‘giant loop’ model, where you initialize settings in the setup() function, then wait for events (inputs, timers, handlers, etc) in the loop() function.

Each time, the loop() function has to finish before it can be called again. So if there are timing related actions, there’s a chance they may fall out of sync or stutter. If you want to advance an animation frame, you’ll need to maintain all the state, and hope the loop gets called often enough so the frame can advance. If you want to sync up the animation to an RTC, then you’ll want to track whether the current loop syncs up with a time code before deciding whether to advance the animation (or not). Pretty soon your giant loop will likely get complicated and messy.

Another option is to look at something like SoftPWM for controlling LEDs and see how they set up animation timing. Or to use the millis() function instead of delay() to manage timing. Adafruit has a nice tutorial on that: https://learn.adafruit.com/multi-tasking-the-arduino-part-1/using-millis-for-timing

To get more asynchronous activity going, the next option is to move to a more task-based system like FreeRTOS. Here you set up ‘tasks’ which can yield to each other, so you can have more asynchronous events. But the mental model is very different than the Arduino loop. The toolchain is also completely different. Here’s a decent primer: https://controllerstech.com/freertos-on-arduino-tutorial-part-1/

If your target device is an ESP32, the underlying OS is actually FreeRTOS. Arduino is a compatibility layer on top. So you can use the Arduino IDE and toolchain to write FreeRTOS tasks. Many peripheral device drivers can also be shared between the two. However, the minute you switch to tasks, the Arduino loop doesn’t work any more. Examples here: https://randomnerdtutorials.com/esp32-freertos-arduino-tasks/

From your description, it sounds like you may want to switch to FreeRTOS tasks.

When do we get to try it out against the creative, destructive power of a hangry toddler?

Hol’ up. Coffee and red wine OK to give cats?

OK, just tried it with one of those old forms. Added a text field overlay and a signature. Even flattens before saving. Works great. Awesome, thanks!

Sounds like he’s on-the-fence about it.

Went to look up what XFA forms were (https://experienceleague.adobe.com/en/docs/experience-manager-learn/forms/document-services/pdf-forms-and-documents).

Most of the non-fillable forms I encounter are what that document lists as “Traditional” PDF forms, likely generated using older tools from print streams. For example, a school athletics release form, or a membership application for a small organization. None of them have any fillable PDF fields. The original expectation might have been to download and print out the PDF, hand-fill it, then fax the result back.

I’ll dig up a form like that I had to fill a few weeks ago and give it a try.
