In my last post I dove into the Epoch implementation. The Epoch is explained very nicely in the paper, and the code follows the paper pretty closely. The code make sense, but I still lack the proper… feeling for how it is actually being used. The Epoch allows you to register code that will be executed when the epoch is updated, which is the key to how FASTER is making progress, but while I can see that this is being called from the alloca....

Governments and corporations realize personal data (consumer, creative, social, etc.) is the most valuable commodity. Tremendous wealth is generated from this, so a type of Universal Basic Income is established whereby people trade their data for a baseline standard of living. The poverty rate plummets and the move is heralded as a huge societal win. […]

In our previous article we looked at the absolute basics: definitions of data structures and algorithms, how to prove our algorithms are sound, and ways to identify the types of objects we’ll want to use when solving problems.

After going over the paper and the managed implementation , I’m ready to start with the C++ implementation. I have higher hopes for this code. As I started browsing the C++ code, it occurred to me that the way the C#’s implementation handles dynamic code generation is pretty much how templates in C++ work. I wonder if this was the trigger for that. The C++ code reads a lot more naturally to me. There are some nice tricks that are used t....

This month we held our quarterly hackathon event- called ShipIt Day. We would like to thank all the participants for making ShipIt Day XII a huge success. With 75 participants, we had associates representing 13 different organizations across Cerner. These associates were given 24-hours to meet the requirements of this hackathon which included making something that was innovative, usable, and value-adding. As the clock ticked down, our assoc..

It’s almost the beginning of September, time to get back to school, everyone! I recently decided to do my Oracle SQL Tuning and Performance & Troubleshooting training classes again. So I will also run some free hacking sessions for promoting these classes, but also for sharing cool new stuff with people who can’t attend the training and of course for fun too! The hacking sessions do not follow a formal training structure, have very ..

Before heading to the C++ implementation, I thought I would take the time to just walk through the FASTER codebase as it is performing a simple operation. The access violation error that I previously run into has been fixed, so I could run the benchmark. Here is my configuration: I got the following results, when running on a single thread. Total 142,603,719 ops done in 30 secs. This is about 4.7 million operations per second, whi....

I wrote before about Crisp and how pleased we are over the migration to their service. Recently they started offering a new service of status page. This service runs on their servers and essentially monitors whether our service is down. Due to the complexity of our service not all of the pieces are monitored but a few of the more important features are already mapped. Hopefully, if you experience service issues you can look in the statu..

This is something that catches me out from time to time, as I have to worry about it so infrequently. When setting up Opengraph metadata on a new site, snippets might display correctly on Facebook's Opengraph debugger but when you share a link on WhatsApp you don't get a link preview (or do and the image is missing). The metadata required is listed below, but 9 times out of 10 it's because I've not included itemprop="image" on the og..

Programming interviews are a major source of anxiety and angst among the software community. Every few months you see a post on HackerNews saying that we need to seriously rethink how we should be interviewing candidates in the software development profession. The primary reason has to do with how programming interviews are structured today.

Last post commented on the FASTER paper, now I’m getting to reading the code. This is a pleasant change of scenery for me, since FASTER is written in C# (there is a C++ port that I’ll also be going through later). As someone who spend most of their time in C#, that make it much easier to go through the code. On the other hand, this was clearly written by someone who spent most of their time in C++. This means that naming conventions and ....

In February I wrote about a new/improved way to build for iOS without the screenshot process . That was a bit ahead of its time as the xib build didn’t disable the screenshot process yet. This is now fixed and it’s turned on by default now. That means that if you send an iOS build it won’t go through the screenshot generation process. This means that apps with native peers in the first screen such as maps, browser etc. will start working..

The FASTER is a fast key-value store from Microsoft. It’s paper was published a while ago and now that the source is available, I thought that I would take a peek. You might say that I have a professional interest in such a project . I decided to read the paper first before reading the code, because I want to figure out what isn’t in the paper.

This article was originally published in 2014. Anniversaries are peculiar things. On the one hand, they are artificial, post hoc pinpricks on time's continuum. On the other, they are a place to stand, to reflect and to make sense of what came before. As it is Thoughtworks 25th anniversary, my colleagues suggested that we revisit an article I wrote that makes its own attempt to slice and dice time for easy consumption.

I try to write about every new feature or capability we introduce but this isn’t always possible. Tasks sometimes weigh me down and as they do so I sometimes find something that I totally neglected as it was released. Such is the case with the CN1Webserver library which we launched over 6 months ago. It got lost and in fact it came out during such a busy period I completely forgot about it.
