One of the problems with software these days is when developers knowingly or (more commonly) unknowingly develop insecure solutions. Saying "it's an architect's problem" is buying into the culture that enables this. If--as you've mentioned--you've analyzed the problem and determined you don't need to know something, then move on. But be aware of the issue and remember that you may not be around to explain (or remember) today's decisions for the eventuality that scalability necessitates a modification.
Saying that the solution doesn't merit security because of its lack of ubiquity is ignoring the fact that cyber-criminals can easily gather formidable bases of data by taking advantage of lack of security across the multitude of solutions that didn't think security was merited. In fact, most sensitive data available to criminals these days is not gathered in one fell swoop, but combined from many sources that have been compromised.

I think understanding at least basically how it works will make your code better. For example, if you send a message and expect a response - understanding some of the things that might make it take longer - such as the effects of latency for example will make the difference between something that works, and something that works well - even on slower networks.
There's a lot of developers who get by without these skills - and if you have a good relationship with you sysadmins, then you can make it work.
By way of analogy - you don't need to understand how your car works to be a good driver, but you do need to know something about the car - or when it needs fixing, to safely make an interstate trip in it. Otherwise you might make it - or you might become friends with the RACV.

I'm staying in digs in a tiny town (pop: about nine, give or take three), next to a church and graveyard, whilst working in a nearby city.
As always, I leave my laptop in the room, with the camera running to take pictures when anything moves.
The desk is in the middle of the room, away from any curtains, etc, that could blow in front of it, and nothing in the room can move of its own accord. And the window was closed.
But something moved, today. I got over 400 pictures, compared to the usual 50-100.
I've cut out all the pictures that were taken because of changes in lighting (there's a picture window less than eight feet behind the laptop, so clouds trigger the motion detector).
But that still leaves 318 pictures -- which are pretty big (over 20meg), so I've dumped them in a RAR file, and uploaded it to Mega.
This is not a spoof, and I am not taking the p1ss (I do do spoofs, and I do take the p1ss, but I don't lie). The laptop was set to take snaps when it detected movement, and no humans entered the room (if they did, there would be pictures of them). They are real photos, taken automatically today, by a laptop camera that was not malfunctioning in any way.
Download only if you want the sh1t scared out of you.

I suppose the obvious explanation of an insect, probably a fly, crawling around over the lens would be just too prosaic to consider?

Damnit!
Let the tension build up a little, eh?
My initial reaction was "WTF!!!" (because until you realise what it is, you can't figure the distance from the camera), but there were two flies trapped in the room, so it was pretty obvious what had happened.

i was just about to ask if you ever noticed any smells like sulfur or if it sometimes feels like it's cold...
but it could be bugs too i guess...

What did you have to do to set up your laptop like this?
If it's not broken, fix it until it is

I use YawCam[^], and a desktop manager.
I open it in a background desktop, and it saves the photos to both a local directory and a web location (a domain that I use for this and this alone).

Grew up in a large family (9 children), so, there was usually someone entering or leaving the house.
I can hear my parent yelling at us, "In or out! But shut the door!"
In regards to Brexit, that thought just made me smile.

I read a lot and I really enjoy technology so when I find a well-written book that describes a technology in a fun way I really like to talk about it.
I'm attempting to build a bluetooth-based controller so I can open my garage door from any bluetooth enabled smart phone (with a code) and I'm reading a book on Atmel AVR Programming.
Have any of you read this fantastic book on Atmel AVR Programming?
AVR Programming: Learning to Write Software for Hardware, Elliot Williams, eBook - Amazon.com[^]
I really like how the author states the purpose of the book.
And so we come to my sincerest goal in writing this book instead of simply another blinky-LEDs-on-an-Arduino manual — to turn you into a true microcontroller type. Although the Arduino environment is good for getting people hooked on microcontrollers, it’s a cheap high. Arduino/Wiring goes to great lengths to abstract away from the microcontroller’s hardware. Here, I want to teach you about the hardware — because it’s useful — so getting further away from it won’t help. (My friend Ash once described working with the Arduino environment as being “like knitting in boxing gloves.”)
The open source hardware community is so cool and you can buy these little components and experiment so cheaply now. Have any of you tried some projects?

Yes, I absolutely knew about the first one you mentioned.
Really great article. Enjoyed that immensely.

Listen to some good music? Enjoy a good movie? Perhaps something that civilized people do is a nice change from sports

Well, that's a problem, right there! And I'd have to sign up to some streaming service or other and ... well, it ain't happening.
On the plus side, I have had a shave a whole day early!

You would need somebody to recommend some decent music also, and we don't have anybody that does that.

Just backed for movie(I'm 2026th backer). Here Jan Svankmajer works' wiki page[^]. If you're fan of Svankmajer's or Stop-motion animation or Surrealism, this campaign is for you. I always liked his works, both shorts & features. Unfortunately People like me won't have a chance to see his movies in theatres in our country because here local distributors bring only blockbusters & commercial Hollywood garbage. At-least these kind of campaigns let me give them something directly which is great.
I rarely share campaigns here, I think this is 2nd time after shared Jodorowsky's[^] last year. I think after a decade or two, we won't have film-makers like these unique indie guys any more 
Thanks for checking the campaign.
