So girls think I'm worse than serial killer and child molester? Do you?

Don't be daft.

Also, stop talking about girls like they're some sort of homogeneous group or something. Some girls will probably like you, some won't. That's just how it is with everyone. However, if you want to make it easier on yourself, my advice to you is stop moaning and get on with things.

How do I supplement/complement my RadioShack Electronics Learning Lab with Programming, since software is the direction everything is going?

There's still plenty of electronics design going on, I've just designed a circuit with 1300 components on it, I admit there's also a FGPA and 2 processors as well, but there's a lot of electronics required to support those. Look at a PC motherboard, there's quite a lot of stuff on there to support the CPU, memory, audio etc...

Software is a big arena, it used to be split into 2 main areas, computer programming and embedded programming, the difference being embedded doesn't generally require a screen and interfaces with the real world. My personal opinion is that mobile software is somewhere between the 2, you can develop PC style software but also interface with all the on-board instrumentation. Given that mobile devices are fairly constrained and there are software libraries to do all the instrumentation interfacing hard work for you, mobile programming is closer to PC than embedded.

If you want to combine software with electronics then embedded is the way to go, there are plenty of cheap kits available which give you some analogue and digital I/O. Arduino isn't a bad place to start, but it will be a bit of a shock when you move to something else as Arduino does a lot of stuff for you, making it easy to get going, the 2 processors on my circuit are actually the same ones used in the Arduino Due, allowing me to 'cheat' by developing the software much faster. I wouldn't even have them if I didn't require CAN and Ethernet, the company I work for hasn't put a processor in any control electronics in 30 years, back when the Motorola 68000 was all the rage.

Is this where engineering inspiration comes from:



movies that promote durability, back-up/auxiliary power, and failsafes in technology?

Is this where engineering imagination comes from:



cartoons depicting modular design in robotics ad code?

Does science depend on art to create something new? It seems like the people that design software are not engineers, but artists, writers, and producers. They seem to be the ones with the ideas, and the engineers just implement those ideas. The engineers seem expendable and the artists appear to have job security and the golden parachutes.

Are engineering and creativity two different things, like sex and love?

I guess it could inspire people to some extent, most engineers I know do their best in those areas because it's the right thing to do, not because they saw something in a film.

No, modular design has been around for a long time, depiction of such things is usually some time after its invention simply because it takes the arts a while to understand how to portray it usefully.
Some would argue that shows like Star Trek inspired technical innovation, certainly it has inspired people to attempt to solve some very difficult challenges. Notice though that communicators have been getting bigger again, they have not shrunk to the size of badges pinned to our clothes, can't say I ever saw an iphone in science fiction before it came out.

No, software companies hire artists and writers to create art and stories for games, programmers write the code incorporating the produce of those artists. Unless the artist is also an engineer then they won't be writing code (software is an engineering principle by definition).
Artistry requires the availability to think freely without constraints, engineering doesn't allow this due to either the laws of physics and/or limitations in the code environment.

It depends what you class as an engineer. With a few exceptions, Artists will come up with bollocks that isn't practical or possible, but that's not their fault, they're artists not engineers. The engineer has to actually engineer the solution to the problem that is being solved, you can't Art your way there.

I don't know any artists with job security, except those who are teachers because that's all they can do with their art degree.
Engineering isn't as safe as it used to be either, especially if you're in fashionable engineering like mobile tech and the internet of things, which I have always avoided getting into for that reason.

I think so, but, much like you can make love while having sex, you can be creative with engineering solutions (within the laws of physics!).

This is what I'm working on at the moment:
https://en.wikipedia.org/wiki/Britis...ass_319#Future
There is no way anyone can Art their way to a solution for this, however, it is taking quite a lot of engineering creativity to come up with something that works there's a lot more to it than just shoving in an engine and alternator at each end. I can't tell you the solution but one of the problems is, you have an engine with limited power which is replacing the 3rd rail which effectively has unlimited power available, how do you limit the power taken by the traction system to match the engine power without changing any of the traction electronics? (we are specifically not allowed to modify the existing electronics). Oh, and the available power isn't constant and you have to share the power between the 2 engines on a common DC bus, 70 meters apart.
I don't think I'd enjoy painting fruit as much as this

Aren’t mobile electronics and IoT (ie. the internet of things) the future. Won’t it make us all into Batman?

Mobile electronics and IoT devices are essential to my crime fighting career:



If this railroad system had been software-defined and software-driven, wouldn’t solving this problem just be a matter of writing and modifying some code?

I have my doubts on the IoT, companies are keen to push it because they want to make money, but who really needs an internet enabled kettle? It has already been shown that these IoT companies can't be trusted with security.
It's more likely to turn us all into Forest Gump than Batman, we will forget how to turn a light on because it's all done for us. People will be calling their tech nerds for help when their lights only come on during the day...

The original system does indeed have software controlling it, but, we aren't allowed to modify it, we don't have access to the code anyway. To overcome the problem absolutely requires some bog standard electronics.
Code can do lots of things, but when you add 2 diesel engines and some additional electrical system to support them, you're going to need some hardware to interface with it. Actually, quite a lot of hardware, we've designed 9 different PCBs for this
I will admit, there are processors in the design, but all they do is communications.
