JSONB in Postgres is absolutely awesome, but it’s taken a little while for libraries to come around to make it as useful as would be ideal. For those not following along with Postgres lately, here’s the quick catchup for it as a NoSQL database. In Postgres 8.3 over 5 years ago Postgres received hstore a key/value store directly in Postgres. It’s big limitation was it was only for text In the years after it got GIN and GiST indexes to ma....

AdRoll uses large-scale machine learning to bid intelligently in internet advertising auctions. In this post, we explore some of the engineering behind the data pipelines that feed our learning algorithms, in particular our real-time system that constructs features from event streams. #Overview If you have been served a banner ad on the internet in the past few years, there is a good chance that ad was served through a process known as....

Note: this post was originally written for the Go Advent 2015 series, but I discovered that a post with almost exactly the same subject (and even similar code!) already planned :) That’s amazing. Golang is often used for writing microservices and various backends. Often these type of software do some computation, read/write data on external storage and expose it’s API via http handlers. All this functionality is remarkably easy to impl..

Dart SDK ships with an analysis server . Very handy if you'd like to write a completion plugin for your favorite editor. The API is well documented . Of interest, there's LocalDartServer.java , part of dartedit . $ dart path/to/bin/snapshots/analysis_server.dart.snapshot --sdk=path/to/dart-sdk NOTE: The server reads requests from standard input. Either escape or execute the following as one-liner json requests. { "id": "1\n", "me..

Part One: Bow to Your Sensei These tips are the dojo ground rules you must learn before even the most basic command line work can get done. If you haven't got these down, everything is going to take much longer than it needs to. These are also definitely a prerequisite to any command line activity while pair programming if you don't want your pair to pull their hair out during the session. tab completion The shell can help you out wit....

This is the first year that I’ve been to the World of Commodore event in Mississauga, Ontario. It’s a yearly gathering of Commodorks who create new software and hardware for vintage Commodore computers. I had no idea that it even existed until someone I knew told me about it. Since it’s relatively close to me, I just had to go. Plus, I have many Commodore computers in my vintage computer collection.

Since Docker 1.9, the multi-host networks can be used very easily. All you have to do is just setup your Swarm cluster and use docker network create -d mynet and voila: Your multi host network is ready. I want to do a benchmark of this new feature, however, the official multi host networking examples are in Virtualbox and local performance can be misleading. I created an image called mustafaakin/alpine-iperf just has the Alpine image plus i..

Desiccant . I really enjoy the way that word sounds. It’s like a discount version of decadent , except that it hasn’t been soiled by rampant overuse in chocolate commercials. I was curious as to its etymology which, as you’ll see above, isn’t nearly as exciting as I’d hoped. I had never even heard of the word until a reader, known only to me as “BoscoBob”, brought it up in an email.

I’m excited to announce Snyk is now live! Snyk helps you find and fix known vulnerabilities in your Node.js dependencies. These are publicly documented security holes, making them easy for attackers to track and exploit.

It’s been a while (six months almost to the day) since I did my last big Home Improvement post , and I think it’s about high time we changed that. Not only because a lack of Home Improvement posts signals stagnancy on the front of truck-progress, but also because there is much to be improved upon truck-wise, and I should be more proactive and motivated to work on it. This, as is likely evident from the title, is just a “Mini” Home Improv..

The advances and growth of our Selenium based automated testing infrastructure generated an unexpected number of test results to evaluate. We had to rethink our reporting systems. Combining the power of Selenium with Kibana's graphing and filtering features totally changed our way of working.

First some background–I’ve always had a bit of a love hate relationship with ORMs. ORMs are great for basic crud applications, which inevitably happens at some point for an app. The main two problems I have with ORMs is: They treat all databases as equal (yes, this is a little overgeneralized but typically true). They claim to do this for database portability, but in reality an app still can’t just up and move from one to another. They do....

If you haven’t read the previous parts of this series yet, here are the links: [ Part 1 | Part 2 ]. A Refresher In the first part of this series I said that RAM access is the slow component of a modern in-memory database engine and for performance you’d want to reduce RAM access as much as possible. Reduced memory traffic thanks to the new columnar data formats is the most important enabler for the awesome In-Memory processing perf....

Trainspotting Definitely not the word I’m looking for, but it sounds cool I noted early on that I wasn’t the only sketchy-looking vehicle on campus. And the longer I’ve been doing this, the keener my eye has gotten to the subtle, but telltale signs of “unconventional” or otherwise “alternative” living situations: windows tinted a little too deeply, parking just slightly farther away from a building than everyone else, a f..
