Programming has not only given us smartphones, tablets, and extremely useful software programs, it has changed the way electrical and computer engineers are designing circuits. For example, an LED effect such as a blinking light could be built using a 555 timer circuit rather simply. However, using a cheap MCU, the circuitry is less complex and a few lines of code can achieve the same effect. It is even possible to create much more complex lighting effects using just a few more lines of code.
The first general-purpose 8-bit microprocessor in the world was the Intel 8008. After its introduction, MCUs quickly began replacing discrete logic. Due to their small size, ease of use, and programmability, engineers quickly welcomed them into the field. However, in the 80s, memory was scarce and even more important, it was expensive. In January of 1983, memory was approximately $2,396 per megabyte, whereas today it is approximately half a penny per megabyte. Consequently, the cost of memory in the past put a limit on the applications MCUs could be used for. Engineers needed to program with caution, making sure their code used as few lines as possible and did not surpass their memory limit.

Today, MCUs are cheap and memory is abundant. Furthermore, MCUs have been integrated into products we use every day such as: displays, printers, keyboards, phones, washing machines, microwaves, and most importantly, cars. A new luxury car today could consist of hundreds of MCUs.
With all the great development in software and MCUs up to this point, it is imperative that engineers build a strong foundation in programming. Programming not only gives people a deep insight on how computers work, it opens up a large array of new tools you can use your computer for. Overall, programming has made our lives unbelievably technically involved. Programming is the powerful force driving modern day technology, and we still have a long road to drive.
Other notable happenings in 1982:
Sun Microsystems incorporates.
Adobe was founded, placing PostScript description language in the Apple LaserWriter.
Symantec was founded, mostly selling security and information management software.
Hercules, maker of high-resolution screens, was founded.
Maxtor was founded, now absorbed into Seagate.
Commodore 64 sold with 64 kilobytes of RAM for $200, the fastest selling computer of all time.
HX-20, the first notebook-sized portable computer, debuted.
I cut my teeth on an Apple II! Learned programming in assembly language on a Z80 processor. And quickly moved to Fortran and C. I have been out of the electronics and computer programming for over 20 years and am just amazed at what the people can now program. Gone are the days of trying to fit code into 2K of memory!
With my youngest starting college, I am once again getting reacclimated with C++ and am amazed at the extension of this programming language. Then I discovered visual C++. WOW! Even an oldtimer can get into the new stuff!
Virtual Reality (VR) headsets are getting ready to explode onto the market and it appears all the heavy tech companies are trying to out-develop one another with better features than their competition. Fledgling start-up Vrvana has joined the fray.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
While every company might have their own solution for PLM, Aras Innovator 10 intends to make PLM easier for all company sizes through its customization. The program is also not resource intensive, which allows it to be appropriated for any use. Some have even linked it to the Raspberry Pi.
solidThinking updated its Inspire program with a multitude of features to expedite the conception and prototype process. The latest version lets users blend design with engineering and manufacturing constraints to produce the cheapest, most efficient design before production.
