   I went from performance work / data science tools at Facebook to PM at MemSQL. A big part of my job is enterprise sales engineering (SE) work, pairing with account executives (AEs) around the country as we fill out our SE team. The fun

   Not quite. Demand is going up faster than supply. Add in rent control and other local oddities, and you get some absurd situations, ike perfectly qualified people leaving the area. My rent is about 40% of the going rate for the identical ap

   All I can say is "it's on the roadmap." :) I used to do a lot of analytics at Facebook and am now a PM at MemSQL, so it's one of my priorities.

   This is a fantastic article from Boz. I have to be blunt in my criticism, however, as I imagine Boz would expect and appreciate. I had a few run-ins with him in the early 2010s and I don't see much evidence that he learned from these e

   Good work! when I was at FB I rolled my own, called "gitsh": https://gist.github.com/aristus/2304335 One of the most useful features is range selection syntax, eg, run git rm on items 4-16.

   Progress isn't just about the upper bounds of human achievement, but also the average. I think it's a mistake to confuse the two, or to place one too high above the other. Of all people you should appreciate that. :) If the next g

   Fair enough; though I'm intrigued by the mention of trillions of polygons. How complex are they? 10 points? 100? 1000? What benefit does the raw data give that centroids can't?

    I respect the author's experience, but "Database Engines Cannot Handle Real-Time Geospatial" is probably not true. We (MemSQL) have developed geospatial on top of our existing skiplist indexes, and can deliver thousands of in

    This is a good post, Thomas. From this I think I could make an efficient test for the kind of person who'd make a good performance engineer. Developing a more general work-sample for developers is a harder problem, but still feels doab

    It has all of the trappings of a successful slogan: definitional, pithy, & ambitious-sounding enough to make everyone ignore the bad math. Berkshire itself is on that list, so surely there are only 489.5 to go. :)

    1. Never use a metaphor, simile, or other figure of speech which you are used to seeing in print. 2. Never use a long word where a short one will do. 3. If it is possible to cut a word out, always cut it out. 4. Never use the passive where

    I have a copy of this, reprinted in 1940s sandwiched into another work by MacDougall. Lots of fun for a bored child. I still shuffle cards in the rather striking way he describes: Cut the deck perfectly in half. This is easier than it sound

    I don't know about that but it helps to ask your CPA (also, get a CPA), and have proof (eg, lease / mortgage, etc) of residency handy. CA once went after me for income I had earned years before I'd ever lived there, and sorti

    This is a feature, not a bug. :) Uber has created a market with dynamic pricing, but manages to keep both ends of the transaction in the dark until the last possible moment. This information asymmetry is precisely why they are making money

    Or, perhaps, companies should become smarter about recruiting and hiring the large-but-unknown "false negatives" that are generated by their current process. Easier to implement, a competitive advantage, and you don't have to

    I'll refrain from gushing about grandma's pan coated with 70 years of lard & love, etc. :D It's not for everyone. But I will say you should skip the teflon and buy an enameled pan instead. They can be quite cheap and are

    At a guess, they are using MLC (or even TLC) transistor configurations, which effectively packs more bits into on transistor, but is slower to read. Good SLC has read cycles of 20-25 usec.
