Can anyone doing Phoenix in production share their typical HTTP response times? I built a small Phoenix project about a year ago, and compared to Rails it wasn't quite as fluent but still pretty nice. But ever since then, I've bee

Okay, I appreciate the reply! I admit they had some good points about problems they found in some TSQL2 edge cases (mentioned in that paper of theirs). I will reconsider how quickly I get to their temporal book. I agree knowing a more pure

Thank you for range types! They are awesome and I have lost count of how often I've used them. I even have a blog post you might enjoy about defining an inetrange: http://illuminatedcomputing.com/posts/2016/06

I saw your note in the post apologizing for making up your own terminology. I wouldn't feel too bad. In the SQL world no two authors I've read use the same terminology for these things! :-) Perhaps some terms are more "standa

Temporal tables are a pet interest of mine, so here are some links that people might find useful: Richard Snodgrass, Developing Time-Oriented Database Applications in SQL . Hugh Darwen & C.J. Date, "An Overview and Analysis of Pro

I watched your video and I am tempted to sign up (as a freelancer). I guess Toptal is a competitor, as someone who claims to offer elite talent. I like how unlike them you don't seem to require lots of CS algorithm quizzing and a big u

Indeed after ruling out HLL I decided that was the way to go. :-) I guess an HLL is more appropriate when you can't so easily keep track of which items have already been added to each set. For example if you were counting unique visito

I was interested in using HLL for a project where I had ~20 million objects and each had a "status" with about 6 possibilities. I wanted to get fast counts of how many objects were in each status. But their status can change over

I'm reading this book right now too. It is sort of my bedtime reading. I've used Linux since 2000 and Solaris before that, and I do occasional C but mostly Ruby/Python/Java. At first a lot of it was stuff I knew, but rea

I've only glanced at this, but I love the idea of making your API be SQL. I did this recently for a company whose customers have a lot of "power users" who are not professional programmers but use tools like R, Excel, Tableau

Something that has tripped me up a bit with service workers is this: I can use the service worker to cache all the things, and I can embed their hashes in the service worker so it knows when to refetch code that has changed, but how do I te

I've used Vue for a couple projects now and it's my favorite SPA framework by far. But I liked Knockout too, and now that feels abandoned, and I'm afraid Vue will suffer the same fate. Will it really stick around in the face

I wrote the initial patch for the UUID support! It's my only Postgres contribution so far (except for docs), and I really only write C a few times a year. I made a few revisions but as I fell behind others picked it up and got it over

No, and I've set it up many times. It's just . . . whenever I talk to people about this I get the impression they think it secures them against more. Non-technical people especially (but not just them) worry about someone "ha

Totally agree about the encryption. I've set up databases to run on encrypted disks (LUKS or nowadays on AWS you can get encrypted EBS), but I feel like that is really just to tick the "encrypted at rest" compliance checkbox,

Another breakthrough I recall was understanding that there are three alternatives: move, copy, borrow. I don't know about the docs nowadays, but when I was starting it seemed like explanations would always pick two of these and describ

That is true, but personally I think about that as coming "after" all the ownership stuff checks out, and as an implementation detail that I can usually ignore. I do keep it in the back of my mind though. Btw I have a saying: when

Yep, trusting every submission initially is fine, and we do use tricks like you suggest to flag suspicious accounts. For instance if you submit "11111" then "11112" then "11113" on up through "99999"
