Wow. So, I was preparing for technical interviews I came across that post from 2009. And the values in the tables seemed relevant but potentially dated. And so the question to HN is directed toward whether those values are still valid, and whether other values are relevant now. The title of the post is a reference to the title of the OP.
- dahart 7y agoOh, I think I completely missed that it was a question. Having this comment in the original question probably would have helped. So, to answer the question, there are definitely some numbers in that chart that are closely related to the speed of light, so they can’t ever change. Most other numbers are still reasonably close due to the end of Moore’s law. But, the list itself feels a little dated since it references spinning disks and doesn’t mention SSDs. These days, I’d maybe include something about modern GPUs, number of flops & typical memory/bus bandwidth. It’s also fun to extend your posted chart with longer times like around the world, or out to geosynchronous orbit or the moon and back. I do sometimes ask an interview question about what is the fastest way to get a terabyte of data from LA or NY with specific assumptions, or something along those lines.
