Yes, I meant that I don't think they're holding an entire web index in RAM.

I had missed that sentence, but also I never said it's impractical.

Read the last part of my comment, I suspect they don't use it for the main web index but only for the fresh subindexes. A search engine like Bing can have multiple indexing systems in production for different use cases.

I'm one of the authors of the paper they compare against (Partitioned Elias-Fano), and since I saw the StrangeLoop talk I've been curious to see a more detailed description of the index, so I was very eager to read the paper as so

I agree with the overall sentiment, but I don't think that any WYSIWYG alternative exists yet that: - Interacts well with version control: it is trivial to maintain a LaTeX document in a git repo, and the diffs are readable (especially

Yeah, it's something that needs to be tuned per-service. It is quite easy if the service is X-bound for some local resource X (CPU, disk, flash, network card), but if it is bottlenecked on external service calls it can be quite challen

A classical solution is to use a control algorithm (for example PI or PID) to avoid having to estimate the overload threshold: the server will just start shedding a fraction of the requests to maintain some metric (CPU utilization, latency,

If you look at the actual papers [1, 2] they don't mention security even once. I believe the security angle was just a PR spin added to the blog post. This is a tool for compiler writers to reason about the correctness of optimizations

Well of course, they're different trade-offs. Here we don't care about flexibility, we're talking about a specific syntax (JSON). Also SSE will be beneficial only if your strings are long enough. I'd be curious to benchm
