I think I am long overdue for writing a post about how we run infrastructure at Zapier. While I admit our setup might be far from perfect, I feel it works well and has served us as we scale the business out. I am also proud of how much we have been able to do with such a small team! Philosophy Since the beginning, we’ve been big on maintaining a philosophy of “Immutable Infrastructure” and treating our instances as cattle, not pets.

I have been working on real time indexes with Sphinx recently for the next version of searchcode.com and ran into a few things that were either difficult to search for or just not covered anywhere. The first is how to implement a distributed search using real time indexes. It’s actually done the same way you would normally create an index. Say you had a single server with 4 index shards on it and you wanted to run queries against it. You ..

Sometimes a small experiment on the side can grow into something valuable. We at Cerner have long used forward-chaining rules engines to express and execute clinical knowledge, but we’ve also had to extend or work around the capabilities of such engines. Engines targeting business users just weren’t expressive enough to model some of our logic. To meet this need we are making Clara Rules an open source project driven by Cerner Engineering.

The most reliable way to evaluate programmer candidates is to hire them to do a bit of realistic work. This is widely understood, but not widely practiced. The biggest barrier is finding projects for them to work on. In most organizations, the overhead of getting a new person started is

I’ve noticed that on my social media feeds a lot of people are deeply upset that Donald Trump was elected President. Well, technically, he hasn’t been elected yet. The Electoral College will meet on Monday, December 12th, 2016 in their respective state capitals to cast their votes, but it’s highly unlikely anyone will be a faithless elector .

Another ShipIt Day was held on September 8th-9th at the Realization Campus at Cerner. ShipIt is a 24-hour hackathon with the goal of building something awesome, usable, and value-adding within a single day. This fall marked our sixth ShipIt, which has has grown significantly since our first event. The event kicked off in the morning at the auditorium of our Realization campus. At this point, teams were already formed, instructions were giv..

This is a continuation of my post about clean tea , except this time I analysed the offerings from Tealyra . Tealyra by the numbers: 490 teas (excluding kits and samplers) 175 contain sugar and/or flavourings 187 caffeine-free So I filtered the list to only show teas with: No caffeine No sugar No stevia No flavourings 86 teas on the Tealyra® menu pass my filter for what I would consider to be “clean” which makes Tealyra the best..

In 2011 I wrote : Travel opens my mind to new perspectives and allows me to recontextualize existing systems of thought. While true for me at that time, for that trip; there is nothing magical about travel itself that opens the mind to new perspectives nor helps to “recontextualize existing systems of thought”. One must be ready and “in the mood” to open ones mind and experience life from a new perspective. The distance travelled ....

Environment variables are declared with the ENV statement and are notated in the Dockerfile either with $VARIABLE_NAME or ${VARIABLE_NAME}. Passing variables at build-time The ENV instruction sets the environment variable to the value. The environment variables set using ENV will persist when a container is run from the resulting image. For example: The Dockerfile allows you to specify arguments […]

TL;DR by learning internals a gotcha is a valid construct in a system, program or programming language that works as documented but is counter-intuitive and almost invites mistakes because it is both easy to invoke and unexpected or unreasonable in its outcome (source: wikipedia ) Go programming language has some gotchas and there is a number of good articles explaining them. I find those articles very important, especially f..

For fixed integers $ r > 0$, and odd $ g$, a Moore graph is an $ r$-regular graph of girth $ g$ which has the minimum number of vertices $ n$ among all such graphs with the same regularity and girth. (Recall, A the girth of a graph is the length of its shortest cycle, and it’s regular if all its vertices have the same degree) Problem (Hoffman-Singleton): Find a useful constraint on the relationship between $ n$ and $ r$ for Moore graphs of ..

Met with B from CoC meetup. Also ran into C from ZP. It was a little awkward, as she hadn’t responded to my emails yet. Selling is tough - these projects aren’t going to pan out for weeks, maybe months. Gotta keep going though. Also got bad news about Nani. more cancer has been found. We decided to fly out tomorrow to see M, who was very shaken. got flights for friday evening.

As I posted on the bug report on the Qt bug tracker : Hi, We ran into this problem recently. In my opinion this is a somewhat serious problem with Qt that should be fixed. We noticed this after fixing a bug in our code. A function was incorrectly taking an int argument instead of a double argument, and we were passing a double in. But the usual warning was not reported The usual warning would be something like: warning C4244: 'initial....
