If any of you order cheap glasses from Zenni, it's really fun to look at the network tab of your myOrders page to see how not to do website design / architecture.

If you've ordered glasses from them, you can go to: https://www.zennioptical.com/myAccount/myOrders My page just spins. I was curious where my glasses order was after a couple weeks of not receiving them. The network tab shows 30+ css files being downloaded for a very simple website, 10+ trackers and advertising js scripts, and the page still won't load. How about this: SELECT * FROM orders WHERE customer_id = :id ORDER BY order_date Then you can render my most recent orders on the server and at least render some HTML with relevant data. Ok, at scale that might now work. I understand that. Zenni isn't Amazon or Google, but they probably get many requests. In that case we could set up 1+ load balancers that simply forward the request to a sharded server based on userid to balance the load. It's absolutely crazy that we could handle thousands of requests per second in the early 2000s with a few servers in a colo facility and these days everyone has to pretend their facebook or myspace that needs to analyze complex graph connections between people. I just want to see what the status of my order is. It's not that hard. submitted by /u/DrAwesomeClaws [link] [留言]
