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.
Stroustrup suggests that the origin of the name C++ is related to George Orwell's "Newspeak" described in the appendix to his novel 1984: "any word ... could be strengthened by the affix plus-, or, for greater strength, doubleplus-." This is part of a soi-disant "C" language. See Orwell, 1984, pp 315 and 322.
Siemens released Intosite, a cloud-based, location-aware SaaS app that lets users navigate a virtual production facility in much of the same fashion as traversing through Google Earth. Users can access PLM, IT, and other pertinent information for specific points on a factory floor or at an outdoor location.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
