In the age of bloated resource hogs, I was pleasantly surprised that this rendered with no perceptible lag or stuttering, even on my phone. Impressive how everything is drawn so efficiently.

I wonder how loudness factors into that. Maybe ideas which make their "host" express them loudly have a higher chance of "infecting" others?

Interesting to see the Law of Leaky Abstractions at work: https://www.joelonsoftware.com/2002/11/11/the-law-of-leaky-a... I admire this kind of low-level, first principles exploration which I personally don&#

All-around great product - the best part for me is how there's an offline option, no mandatory app or subscription BS. There's too much of the latter nowadays.

Neat little products, but the graphic design is quite... something. I've got nothing against old-fashioned HTML, but text on a high-contrast image background is pretty hard to read.

"Certain backgrounds"? Any particular examples?

OFDM is one of those technologies that I haven't been able to conceptually grasp. Thinking in a frequency/phase space instead of a (DC) voltage/time space hasn't quite "clicked" for me yet.

For those interested, it's also worth taking a look at the time-integrals (or "lower derivatives") past displacement: absement, absity, abseleration, etc. https://en.wikipedia.org/wiki/Absement

Reminds me of the hours I spent messing around on Tux Paint. For some reason, the canvas is rendering to the right of the top toolbar instead of below it (Firefox stable).

Fun little sandbox. Interesting how when in "yin/yang" mode, the balls seem to stop changing state when the tab is not in focus - is this a feature? I only found this by filling up the screen with a cacophony of balls, and th

I reckon it's a combination of simplifying it and assuming that anyone capable of setting up a VLAN knows enough to sort this one out. That might not hold for more exotic networks (businesses, schools...)

The company (XREAL) behind the glasses they're using seems to be doing that. They have a USB-C version: https://developer.xreal.com/?lang=en

At least the page after clicking the long link tells you where you're actually going, making this about as risky as a regular phishing link. URL filters may have a hard time though.

Agreed. I was about to ask why it didn't seem to work on mobile - that would be it.

Also see the infamous Wii tweezer attack which could dump the system ROM with just a pair of tweezers. Sometimes I wonder how these sorts of exploits are discovered. It must take some serious in-depth knowledge of the target system and a lo

Could someone please explain why the low frequency means the bandwidth is limited to 1 bps? Why can't the signal be turned on and off more times per second to transmit at a higher rate?

Do you have said domain expertise? Of course it would seem obvious if you did. Personally I'm less familiar with IR technologies than RF, so I was expecting some radio-controlled design inside (with an overpowered IC). What they actual

They're using the directionality of the IR transmitter for "addressing", so to light up an area they just point the transmitter towards it and broadcast a command that all the receivers run. Quite an elegant method, in my opi

In embedded systems watchdog timers are often used as a crash mechanism outside of the software itself, which will crash the program if it is not reset. I found this concept of crash-only software pretty neat - time to see if I can apply it

My first contact with ESPHome revived an old ESP32 sunrise alarm clock project of mine whose hardware was all complete but software was half-baked shoddy C++. It has adjustable color temperature (to wake me up with blue light) and can play

Fun little project, wonder if DDC could be used as a way to control devices like HDMI capture cards or KVM switches? Honestly surprised that bare i2c interface is exposed to the OS and not hidden by some firmware...
