Can you do a design for versions control system?

I'll add it to the backlog :)

[@CristianAbrante]

Hello! Which app do you use in your iPad to draw diagrams and explain the concepts?
Great video! 👏

[@interviewpen]

Thanks! We use GoodNotes.

[@Zmey5656]

You always need to think about replicas

[@abhibhagat7767]

Why not enable RAID and set the correct level?

[@shabarinathk8954]

my thought exactly. but people these days need to complicate everything

[@ralphard]

Assume you have to store across multiple computers, RAID doesn’t save you from the host attached to the RAID card dying

[@interviewpen]

When we're dealing with a single node, RAID is of course a great way to implement the concepts we discussed. When dealing with more than one node, we have to do replication over a network, which requires software solutions. Thanks for watching!
