Too bad the infographic didn't include the number of bugs we can expect from all that code...

@AlPothoof: On a slightly different note: if 2013 is such a great time to be in software, why are so many software engineers either unemployed or worried about their current job?


That's a great (if sad) question ... I wonder if we can persuade the folks who created this infographic to answer it :-)

Modern optimizing compilers can do amazing things and, when they're working properly, will probably generate an executeable that is faster and more compact than I could hand code.  Having said that, there are times they will do amazingly BAD things to my code: a simple bit of code to turn a bit on, wait a while and then turn it back off may go away entirely.  A number of my younger colleagues eschew looking at assembly-level output to see how the compiler has morphed their code, then wonder why things don't work properly...

On a slightly different note: if 2013 is such a great time to be in software, why are so many software engineers either unemployed or worried about their current job?  I know way too many in both catagories, at least in the embedded realm.

Click on the link just above the graphic -- the one that says "Click Here" (which I intended to be a clue :-)

@kfield: ...a large number doesn't necessarily mean a good thing...

I'm not a software guy (thank goodness -- I'm a hardware man through and through), but when I was a lad we used to hone our software to use as few bytes in memory and as few clock cycles as possible.

A lot of the "old school" software guys still do this, but I'm not sure about their younger colleagues...

I find it interesting that the measure for comparison is "lines of code," when a large number doesn't necessarily mean a good thing. The really interesting comparison would be showing some modern day product using less lines of code today than in the past, due to better programmers.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
