What’s the coolest technology you worked on?
Throughout your programming career what was the most coolest technology did you work on ?
And how did it helped you progress in your career
A military guy visited our place to give us a plaque of appreciation. He also had a picture. At the base, they asked people whose lives had been saved by our product, to come out for a quick picture. They had over 100 people show up. Being a part of a product that clearly saved all of those lives, plus many more, filled me with pride.
Hard to beat that for compensation, not all salaries are measured in cash.
Early in my career (as a co-op student) learning C on the job, I had to implement the HP PCL interpreter for a printer. The trick was it had so little memory (no page frame buffer) that you had to be very efficient and render into a short-height band across the page as the laser beam is rastering over the moving paper. Luckily I had hobby experience doing similar things on the Atari 8-bit. Some other student did the macros. A magazine did a benchmark test of a bunch of HP and compatible printers. Ours won most benchmarks except for storage efficiency for user-uploaded fonts which HP did better. They may have used more advanced compression. Partway through the project they took the hardware blitter out of spec to save like $12 so I had to replace it all in software including 0.25x,0.33x,0.5x,2x,3x,4x scaling which was also fun.
Not the coolest, but the one I enjoyed working on was a project to port Mortal Kombat: Dead Alliance game from GBA to a puny(but interesting) linux mobile phone. The linux phone had no graphics hardware acceleration where as GBA has. And I am no graphics expert, I am a generalist software engineer and there was no support or documentation* of the original source code and platform so it was super fun ;)
* Don't ask me why, there were some business reasons.
Nothing - I work at a bank it's boring af.
Nothing that cool but did stuff interfacing with hand readers and touch devices in 2002 when that was a new thing.
