There’s a well-understood phenomenon in machine learning called overfitting. The idea is best shown by a graph: overfitting Let me explain. The vertical axis represents the error of a hypothesis. The horizontal axis represents the complexity of the hypothesis. The blue curve represents the error of a machine learning algorithm’s output on its training data, and the red curve represents the generalization of that hypothesis to the real world..

SIMD instruction processing is just icing on the cake. Let’s dig deeper. This is a long post, you’ve been warned. Test Environment I will cover full test results in the next article in this series.

At SoundCloud we have been building for the Android platform since 2010. Much has changed since then: the team has grown, the list of features has grown, and our audience has grown. Today, eight engineers are working full time on the official SoundCloud app, across various areas, with contributions pouring in from other parts of the organization. Due to the growing complexity and number of contributions, the app’s size has grown substantial....

If you get caught in the rush between Newport court and Newport place, you'd likely fail to notice some the awesome street food stands. Chilly squid I've walked past this place many times and never noticed it. They serve a handful of items, but the grilled chilly squid skewers caught my attention. They're grilled, brushed with chilly sauce and finished w....

Roughly a year ago I posted what I expected to be the last entry in my Fiddler series. Each of the seven entries had focused on various ways that Fiddler could help improve our development life cycle. They represented the highlight reel. All isn't perfect though, and where there is a highlight reel, there tends to be outtakes as well. So, here goes: here's a few ways you can use Fiddler to slow down your development process.

SnailLife snail stables have always lived in the ether - in some virtual universe with no physical location. Since I’m trying to make SnailLife based in reality, users’ snail stables should also be based in real locations. This is why now, upon registration, the user’s physical location is used as the location of their snail stable.

So I’ve got a nice and simple NodeJs app and I want to have a CI build which builds my Docker image and pushes it to my docker hub ready for deployment. I’ll look at deployment in a future post, this time round we’ll focus on the build process. To get this setup we’ll need to go through two bits, basically VSO uses agents (machines used to execute builds) and a build, which defines some steps that output an artifact (in this case a docker i....

PostgreSQL has a great feature called Foreign Data Wrappers (FDW) that allows it to connect directly to outside systems. Although the setup can be a little complicated, once it’s available you can run queries with joins or subqueries against them, insert data, create views, etc. Heroku has dramatically simplified the process of using FDW with PostgreSQL and Redis thanks to Data Links. Let’s try it out.

Composition goes beyond the mechanics of type embedding . It’s a paradigm we can leverage to design better APIs and to build larger programs from smaller parts. It all starts from the declaration and implementation of types that have a single purpose. Programs that are architected with composition in mind have a better chance to grow and adapt to changing needs. They are also much easier to read and reason about. To demonstrate thes....

Okay so this is part 2.5 in my series of posts combining my two favorite things, Docker & Tor. If you are just starting here, to catch you up, the first post was “How to Route all Traffic through a Tor Docker container” . The second was on “Running a Tor relay with Docker” . I thought it only made sense to show how to set up a Tor socks5 proxy in a container, for routing some traffic through Tor; in contrast to the first post, where I e....
