Which design guidelines should software follow in order to run reliably? Which guidelines do you use in your day-to-day work? Error handling is a significant complexity in real-world projects, but programming textbooks are often giving very little advice on how to think about it at the higher level. This article tries to fill that gap: We will define what an error is. We will find out that each error has a human stakeholder. We will d....

I’ve decided to learn how the Go runtime allocates memory and this is the first in a series of posts that are going to cover what I learned (and also the process itself: how I learned). These posts are based of my notes for the talk I gave at Gophercon UK in 2018: Slides are available here . In this first post we are going to cover: Memory allocation 101 How the allocator is invoked An overview of the tcmalloc algorithm An overview ..

Continuing my stroll through the FASTER codebase, I want to try to get to the core stuff, not just the periphery. This is a bit hard, because there is a lot of code here and it seems to be hard to find where the real action is happening. I decided to find how FASTER is handling Get and Put operations. There is something called InternalHashTable inside FasterKv, which seems promising, so I’m going to follow up on that. Interestingly enoug....

Would you book a hotel without seeing the images first? No, right? Hence, it's vital to make sure the images are available all the time. In a scenario where a lot of images were deleted, we must have an efficient way of recovering them. This is how we achieved that with Amazon S3 Versioning.

The most secure password in the world is the one that doesn’t exist. You remove the user from the equation with a completely random key. To be fair this has some drawbacks and a password still exists somewhere (in your phone/email) but generally this works rather well… The trick is simple, if we want to authenticate a user we can email him a single use URL e.g. mycoolapp://act-32548b09-d328-4330-8243-d7d30c322e40. As you can see that’s p..

It can be difficult to disassociate the idea that dynamically typed programming languages are tied to byte-code interpreters (e.g. YARV Ruby, CPython, V8, Zend Engine, etc.). But for many languages, a compiled implementation also exists. Cython, Chicken Scheme and SBCL are good examples. In this post I will briefly describe how I built a compiler for my Scheme implementation using artifacts from the interpreter. In doing this, I learned....

The conundrum of choice rears its confusing head during the early days of a big data project. The splintered nature of the data ecosystem inevitably leaves end-users spoilt for choice - right from picking out the platform (Cloudera, Hortonworks, Databricks) to choosing components like the compute engine (Tez, Impala) or an SQL framework (Hive).

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. […]

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....

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..

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..
