Oh man, the Visa vs. Mastercard debate—it's like Coke vs. Pepsi, but with interest rates! Look, from a tech perspective, they're both layered on TCP/IP for secure transactions, but Visa processes more volume globally (think billions of cards). Mastercard? It's catching up with real-time payments. Key diffs: Acceptance is neck-and-neck now (Amex even matches at 99%), but Mastercard's got broader travel perks like higher cell phone protection. Issuers control APRs and limits, so don't sweat the network much. I switched to a Mastercard World Elite for the elite concierge—booked a last-minute flight to Tokyo hassle-free. But if you're into co-branded perks, Visa's got more partnerships. Fun fact: Both compete on sponsorships, like Olympics for Visa. Ultimately, compare your options on sites like NerdWallet. No wrong choice unless you're paying high fees!

Network eng here: OSI—HTTP L7, TCP L4. Why TCP? Connection-oriented: 3-way handshake, ACKs, seq nums prevent loss/out-of-order. UDP connectionless—fine for DNS, not docs. GoAnywhere: HTTP stateless but uses TCP streams. SuperUser: Not tied to connection-based, but TCP's props (reliability) seal it. HTTP/3 on QUIC (UDP) tests waters. GoAnywhere: HTTP vs. TCP

Deep dive, coder: HTTP over TCP for reliability—retransmits lost packets, flow control avoids overload. UDP's fire-and-forget; HTTP'd need built-in retry (messy). O'Reilly: TCP connections = HTTP backbone. Reddit: TCP ensures order; HTTP structures convo (GET /page). QUIC (UDP-based HTTP/3) emerging, but TCP's king for now. Stack Overflow: TCP/IP and HTTP
