Hands-on tutorials for Claude Code, AI agents, cloud and system design
A look at how Zoom works. Zoom handles millions of concurrent video meetings per day with sub-second latency, and the architectural decision that makes it possible is the choice of SFU (Selective Forwarding Unit) over the more familiar MCU or peer-to-peer mesh. That one choice is why Zoom scales to 1,000-person meetings while competitors stall… Continue reading
TL;DR 30 sec6 min coredeep dive optional Machine learning lets software work out its own rules from examples instead of following instructions a programmer typed, and every model in the field trains through one repeating cycle of prediction, penalty, and update. Samuel’s checkers program was already learning at IBM in 1949; a paper he published… Continue reading
TL;DR 30 sec6 min coredeep dive optional Artificial intelligence is a capability of computational systems, software that takes in information about its surroundings and works toward the goals it was given; the working definition promises no copy of a person, and the field’s record never delivered one. The field opened with a 1955 bet that… Continue reading
TL;DR 30 sec7 min coredeep dive optional AI history is a hundred-year cycle of hype booms and funding winters, and the current wave is the field’s third boom: founded in 1956, frozen out in the 1970s and again from 1987, revived after 2012 on data, GPU compute and backpropagation. The groundwork predates the name by… Continue reading
