I went looking for a remote-controlled power switch (the wireless christmas kind, not the modern IoT kind) and didn't find it, but I did find this thing I bought just to figure out why it exists.
It's a timer outlet, but you program it from your phone... but it's not wireless.
probably because iphone dropped the headphone port and they had to get with the 21st century and make it bluetooth
I guess the thing saves settings when turned off, because you have to unplug it to push the reset button.
Specs: up to 10 amps for a resistive load, and up to 5 amps for a tungsten load.
That's putting some serious trust in your SEO, man
although it tries to sell me a bunch of unrelated movies first?
one of my favorite things to do is to look up the ratings on IoT apps... they're never good.
make calls, and access all your files.
and if you deny it, it just dumps you in the settings page to fix permissions, with no message.
We've got a CPU and two smaller chips. Probably one is some kind of communication chip, and the other is a flash chip for storing settings?
L isn't connected... I think that means there's a version of this that can control two outlets at once, not just one.
I do like that they keep all the high-voltage AC stuff separate from the low-voltage DC stuff.
Cheaper versions of this would have just had one PCB.
AND IT'S AN 8051! EVERYONE TAKE A DRINK
because it has a battery, yeah.
because it can tell it's not connected properly, in this emulator I'm using
it sounds like (NO PUN INTENDED) it has a protocol of simple tones that it plays at the device.
android historically has had a AudioManager.isWiredHeadsetOn api which tells you if the 3.5mm jack is connected.
So it may just be detecting there's no headphones plugged in to my emulator.
CT is "current time" as an integer of how many minutes it is into the day, and CD is the day of the week.
(it's using Monday = 001, and counting up from there)
uhhh. I'm not sure I'm awake enough to figure this out, but... it starts by padding up to a multiple of 8 bits.
then it converts that to a binary number, and pads it out (on the left this time) to 8 bits
if it is, it adds a 1?

A fun fact on the wikipedia page for the metal–oxide–semiconductor field-effect transistor:
it is the most frequently manufactured device in history, and the total number manufactured from 1960-2018 is 13 sextillion.
That's 13,000,000,000,000,000,000,000.
Though this picture is a bit misleading.
Even with devices this small, we couldn't make 13 sextillion of them in 60 years.
So imagine a chip like this. It's the 555 timer, which is one of the most popular integrated circuits ever made.
In 2017, it was estimated a billion are made every year.
And at the heart of it is the die, which looks like this:

And that's fundamentally a bunch of CMOS transistors (along with some diodes and resistors), which are a type of MOSFET. How many of them are on a 555?
about 25. Not many, but it's a very simple chip.

On Wednesday, The New York Times published a blockbuster report on the failures of Facebook’s management team during the past three years. It's.... not flattering, to say the least. Here are six follow-up questions that merit more investigation. 1/
1) During the past year, most of the anger at Facebook has been directed at Mark Zuckerberg. The question now is whether Sheryl Sandberg, the executive charged with solving Facebook’s hardest problems, has caused a few too many of her own. 2/ https://t.co/DTsc3g0hQf
2) One of the juiciest sentences in @nytimes’ piece involves a research group called Definers Public Affairs, which Facebook hired to look into the funding of the company’s opposition. What other tech company was paying Definers to smear Apple? 3/ https://t.co/DTsc3g0hQf
3) The leadership of the Democratic Party has, generally, supported Facebook over the years. But as public opinion turns against the company, prominent Democrats have started to turn, too. What will that relationship look like now? 4/
4) According to the @nytimes, Facebook worked to paint its critics as anti-Semitic, while simultaneously working to spread the idea that George Soros was supporting its critics—a classic tactic of anti-Semitic conspiracy theorists. What exactly were they trying to do there? 5/

I think about this a lot, both in IT and civil infrastructure. It looks so trivial to “fix” from the outside. In fact, it is incredibly draining to do the entirely crushing work of real policy changes internally. It’s harder than drafting a blank page of how the world should be.
I’m at a sort of career crisis point. In my job before, three people could contain the entire complexity of a nation-wide company’s IT infrastructure in their head.
Once you move above that mark, it becomes exponentially, far and away beyond anything I dreamed, more difficult.
And I look at candidates and know-everything’s who think it’s all so easy. Or, people who think we could burn it down with no losses and start over.
God I wish I lived in that world of triviality. In moments, I find myself regretting leaving that place of self-directed autonomy.
For ten years I knew I could build something and see results that same day. Now I’m adjusting to building something in my mind in one day, and it taking a year to do the due-diligence and edge cases and documentation and familiarization and roll-out.
That’s the hard work. It’s not technical. It’s not becoming a rockstar to peers.
These people look at me and just see another self-important idiot in Security who thinks they understand the system others live. Who thinks “bad” designs were made for no reason.
Who wasn’t there.
The tragedy of revolutionaries is they design a utopia by a river but discover the impure city they razed was on stilts for a reason.
