The new IoT?

I didn't post this because of the news value, but as a reminder that our nifty little gadgets can be used for more than turning on the air conditioner before one goes home from the office. Kids, don't try this at home!

I would hate to think that my code would wind up in a weapon somewhere. Fortunately that's not likely.

Oh I dunno - judging by QA and SO, some "developers" will copy'n'paste anything into their code if they think it might do what they want. Even if that's just a side effect of the original code ... :sigh:

Do you mean to say that your code has never blown up? :)

Those if statements are designed to test your mettle, not to blow up children. :sigh:

I can't even recall a time I've ever run into the problem {} is supposed to solve w/ if statements. Maybe it's you? :laugh:

I have ... back in the days before editors auto-indented for you. And it was a sod to track down, because I tend to read what I meant to write, rather than what I actually did. :sigh:

I'm still using editors that don't. I guess I'm just wired such that it doesn't trip me up. I always read the next line of non-comment code after an if as conditional. That's just how I work, for better or worse.

if(flag.test_and_set());

would screw me up but nobody would do that on purpose. Not even me.

The problem comes when you get this:

if (a == b)
c();
d();

Or you try to add debugging lines to find out what is happening:

if (a == b)
printf("a equals b\n");
c();
d();

And you start scratching your head to work out why adding debug code changes the results ... :laugh: That's why I always use curly brackets:

if (a == b)
{
c();
d();
}

Even I can't muck it up then! :-D Hopefully. :sigh:

I mean, I get it but even skimming really fast I saw that c() and d() always get called. It's probably just me.

I make this clear by writing

if(a == b) c();

I don't see the need for the line break (or a space after control keywords like if, he says, donning his asbestos suit). But if it won't fit in my self-imposed 80 columns, or if I want a line break for debugging purposes, I add braces:

if(a == b)
{
c();
}

Unless, of course, there's an else clause, which also makes things clear:

if(a == b)
c();
else
d();

But if either the "then" part or else part needs braces for multiple statements, the other one also gets them. Aren't you glad you brought this up?!

That's a seriously irritating article. I feel like they are talking to 5 yo's. fwiw, I know I've read where in Syria, one side was using cheap drones to drop C4 on soldiers. It's amazing we haven't had a swarm attack somewhere. And there is another story where some Australian decided to try and build a cruise missile with nothing but off the shelf components. I think he got it to significant range, GPS navigation, and could carry a "payload" of something like 100 Kg. Yeah, genie is out of the bottle.

Gee ... The 5 yo's you are talking to are quite different from those I meet!

The hardware has obviously existed for a few decades, at least. I remember a regular column in Byte back in the '80s, Ciarcia's Circuit Cellar, in which Steve Ciarcia built all manner of interesting gadgets, publishing the circuit diagrams. Building something like a remote-controlled machine gun would have been simple for him.
