I've been on-call for most of the last 11 years. I was on-call for the CS Department at Mudd1. I was on-call at Yelp, in a rotation that at times contained as few as three people. I was on-call at Uber in rotations ranging from one to twenty people. And I've been on-call at EasyPost — initially in a rotation with one other person2, and currently with two other people. I have responded to tens of thousands of pages. I have been woken up in the middle of the night hundreds3 of times. For the last seven or …read more
Until recently1, my job was to synthesize a deep understanding of operating systems, networking, system administration, and my company's application and to use that synthesis to fix our existing systems and design better ones. A lot of folks in the technology industry (particularly in the bubble of Greater San Francisco) use the word "DevOps" when putting out job postings for roughly those tasks, and I just wanted to briefly write about why this word is somewhere between inaccurate and offensive and why you shouldn't use it.read more
It's been a while since I posted, and I've been spending a lot of time fighting with Redis, one of the darling databases of the NoSQL era, at work, so I thought I'd grace y'all with a brief rant on Redis, what it's good at, what it's bad at, and so on.
Redis is an open-source moderately-structured in-memory key-value store. This means that, unlike full relational databases, it doesn't have a fixed schema, and it can't perform server-side operations like joining and filtering data1, and theoretically it's faster. Redis looks an awful lot like memcache, but …read more
Hello dear readers. I just thought i'd give you a life update, since it's been nearly a year since my last post. In no particular order, some things that have happened since then:
One of my co-workers wrote up this gem on why PHP sucks. I don't agree with his points (having a "development server" isn't an important or even particularly useful feature of a framework, much less a language; prepared statements aren't the pinnacle of SQL), but he does do a good job of showing off some of PHP's more spectacular failings.
I'm naming all of my PHP functions
(yes; I do appreciate the irony of linking to his post from a PHP site)
Brief post. I decided to actually use Github once in a while now (not in the least because I use it for open-source stuff at work). My page is up at github.com/Roguelazer, and the work account which I'm a contributor on is at github.com/Yelp. So, uh, feel free to comment on or improve any code that you see thereabouts.
Also, I am thinking about doing a series on git on this blog, since I get to use it rather quite a lot now, and there definitely aren't enough guides to it on the Internet yet. Yes …read more
