1 year agoI was an embedded developer for years for critical applications that could not go down. While I preferred avoiding dynamically allocating memory, as it was much less risky, there were certainly times it just made sense or was the only way.
One was when we were reprogramming the device, which was connected to an fpga which would also require reprogramming. You couldn’t store both the fpga binary and the new binary for the device in memory at once, but there was plenty of space to hold each one individually. So allocate the space for the fpga, program it, free and allocate space the new processor code, verify and flash.
What am I missing? Have things changed?
I was originally a chip designer. Then I shifted into embedded development. Now I’m mainly a C# guy.
But when I shifted into embedded development, I also shifted into doing power engineering. I grabbed a couple of books on the topic at hand, taught myself a lot, and designed the electronics to meet the need. We sold the product to city utilities.
I remember one time I was in a room with probably 10 engineers from one of the utilities. After having described the product to them, and went through a lot of our settings and stuff, I was explaining the difference between two of algorithms we put in (because different utilities use different algorithms, and I just wanted one device that could do both). At some point I was like “which of the two algorithms do you use?” and one responded “well, which do you recommend?” So I talked about why I thought one was better than the other.
They all started looking at each other and nodding and saying “Yeah, that’s the one were going to use.” I realize I could have said anything at that point and they would have agreed. They thought I was expert. And that was my “last two frames” of this comic moment.
Now as a senior dev, I’ve seen enough shit to realize that most people have no idea what is going on, and are flying by the seat of their pants. So I figure my ignorance is a little less than theirs, and that gives me a lot of confidence, but I also realize that I can learn a lot from most people.
