Ah, you're back. So I've been thinking about page tables.
I'm Srinath. I write C/C++, and I care about software quality and UX, which is a different question from whether it's popular. I like to yap about what I understood or read, cuz then I won't forget it. I also have opinions, so be careful.
Virtual memory, still. Six posts in, starting with one address holding two values, and it hasn't run out of ways to surprise me.
Learning LLD, and also realizing why OOP is not that bad.
Doing C++ drills where I predict what the compiler will do before I run it. A wrong prediction teaches more than a right one.
Taking notes on CSAPP: making programs fast, then the memory hierarchy.
- Is it in Swap or RAMWhere a page goes when it's evicted, and how the kernel gets it back.
- The Fault That Isn't ?Not an error. Your machine handles thousands a second, including right now.
- The Skyscraper Inside Your ProgramHow the stack works, floor by floor.
- SSD & File SystemsWhat happens when you save a file. Grab something to drink.
- Will software Suck ?Stop hiring juniors and you run out of seniors. The short-term saving has a long-term invoice.
- Build || !BuildNo-build used to mean no build.
