pIf you own an Apple Watch, you probably noticed something disappointing: 3rd party apps are SLOW./p pIf you#39;ve written a watch app, you#39;ll know that a big part of the problem lies in the bandwidth limitations of phone to watch communication. Architecting a performant WatchKit extension can be difficult due to the write-only nature of WatchKit UI elements and the stringly-typed nature of controllers./p pHow can we decrease traffic sen....

When addressing the question of what it means for an algorithm to learn, one can imagine many different models, and there are quite a few. This invariably raises the question of which models are “the same” and which are “different,” along with a precise description of how we’re comparing models. We’ve seen one learning model so far, called Probably Approximately Correct (PAC), which espouses the following answer to the learning question:

It’s a bit of a sensationalistic title, but hear me out. And sorry for the boring-ish example in this article. This is designed to only excite people who really get it. :) AWS Lambda lets you run NodeJS code or any binary (or code of any language) as a fast starting and stopping EC2 instance. You can use it to, for example, quickly resize an image as a background worker. What I’ll quickly show you here though is that you could even poss....

Why RavenDB isn’t written in F#, or the cost of the esoteric choice

In a recent post , a commenter suggested that using F# rather than C# would dramatically reduce the code size (measured in line numbers). My reply to that was: F# would also lead to a lot more complexity, reduced participation in the community, harder to find developers and increased costs all around. And the data to back up this statement: C# Developers F# Developers Nitpicker corner: Now, I realize that t....

How to install Percona MySQL 5.6 on Ubuntu 14.04 LTS from a script (i.e. without an interactive prompt for the mysql root password)

Ubuntu 14.04 (and various versions of Debian) come with MySQL 5.5. If you need MySQL 5.6 features (such as better join algorithms) you can install the Percona software, as described here . However, the installation process prompts you for the database’s root password. This isn’t convenient if you’re running the installation process from a script e.g. a Vagrant or Docker initialization script. Here’s the whole script to install Percona 5...

Hi, So I’ve recently been working on programming for the Microsoft Band. In particular looking at streaming sensor data back from the band in realtime to process on my Windows Phone phone and, depending on the data, push up to a cloud service. Out of the box the Band SDK will give you a set of SensorManagers to which you can hook up .NET EventHandlers and then do what you will with the output. However, working with streams of data in ..

A while back, I announced that I had moved my blog over to HTTPS. What about HTTP though? Do I serve content over HTTP still, or did I doom existing links to be forever broken? As you could guess by the title of this post, neither of those was satisfactory. Instead, I added four lines to our NGinx configuration telling it to listen on port 80 and respond to every request with a permanent redirect pointing to the same path under https://josh..

If you’ve followed anything I’ve written about Postgres , you know that I’m a fan. At the same time you know that there’s been one feature that so many other databases have, which Postgres lacks and it causes a huge amount of angst for not being in Postgres … Upsert. Well the day has come, it’s finally committed and will be available in Postgres 9.5 . Sure we’re still several months away from Postgres 9.5 being released, anywhere from ....

Have you ever used an iterator adapter in Rust ? Called a method on Option ? Spawned a thread? You’ve almost certainly used a closure . The design in Rust may seem a little complicated, but it slides right into Rust’s normal ownership model so let’s reinvent it from scratch. The new design was introduced in RFC 114 , moving Rust to a model for closures similar to C++11’s. The design builds on Rust’s standard trait system to allow ....

The concept of object safety in Rust was recently refined to be more flexible in an important way: the checks can be disabled for specific methods by using where clauses to restrict them to only work when Self: Sized.

It’s been long enough that a refresher is definitely in....

A while back Peter Norvig posted a wonderful pair of articles about regex golf. The idea behind regex golf is to come up with the shortest possible regular expression that matches one given list of strings, but not the other. “Regex Golf,” by Randall Munroe. In the first article, Norvig runs a basic algorithm to recreate and improve the results from the comic, and in the second he beefs it up with some improved search heuristics.
