When pg published "What You Can't Say" (paulgraham.com/say.html) in the early 2000s, I wrote him to say that it was similar to this piece by Twain.

The hardware setup is not clear. Are you running YCSB client and the database on the same single A3 instance?

This looks great. Any tips on how to terminate mixed-mode protocols like MySQL's SSL mode and IMAP's STARTTLS? Vanilla unwrapper daemons generally don't handle the case of initial unencrypted bit twiddling, and then SSL negot

I have been there. It's a tall rusty sculpture in a courtyard well inside Langley HQ. The only odd thing I noticed is that some letters are over or below the line. Can't take pictures or rubbings so not much else to report.

Nice! A few years ago I made a little program like this, called packet flight, to visualize network flows. It's a nice way to see the magic: https://vimeo.com/17248120

Tricky question. I was working on perf, so I could avoid the tricky philosophical / data science questions like that. FB did say in 2012 that they believe 8.7% of accounts were dupes or fakes. I can't say what the number is now, n

I think so, rereading. But many people assume that simply visiting a page with a widget counts.

I personally audited the entire pipeline, and code, from collection to analysis all the way to the little DAU ("daily active users") graph that informs this number. That experience, and years of working on related data sets inside

Back when I worked there, I "audited" the systems that count Facebook's active users. I needed to analyze code efficiency and feature growth over long periods of time, and so needed very accurate user counts in order to subtr

After all of that discussion of very Postgres-specific limitations, they blame SQL ? SQL is just a notation for relational algebra. It is not the problem here. There are better, distributed, scalable, write-optimized implementations of rea

I'd take this chart with a grain of salt, given the FB paper. Peregrine is no longer in service, IIRC. It was a friendly rival to Scuba, and was eventually replaced by Presto, which is not even mentioned. Also not mentioned are severa

The software took in the thing the user wanted to do as input, and made up plausible excuses for why it should be done. A rationalization engine, as it were. This is a bit different, more of a constraints optimization problem. If you want a
