This is a lesson that I wished I learnt when I first started using AWS Lambda in anger, it would have made my life simpler right from the start. But, we did get there before long, and it allowed us to track and include correlation IDs in our log messages (which are then pushed to an ELK stack)which would …

When I discuss AWS Lambda cold starts with folks in the context of API Gateway, I often get responses along the line of: Meh, it’s only the first request right? So what if one request is slow, the next million requests would be fast. Unfortunately that is an oversimplification of what happens. Cold start happens once for …
I’m afraid you’re thinking about AWS Lambda cold starts all wrong Read More »
In the last post I compared the coldstart time for Lambda functions with different language, memory and code size. One of the things I learnt was that idle functions are no longer terminated after 5 minutes of inactivity. /2017/06/aws-lambda-compare-coldstart-time-with-different-languages-memory-and-code-sizes/ It is a fantastic news and something that Amazon has quietly changed behind the scene. However, …

Read the whole series: Part 1 — type inference Part 2 — traits Part 3 — case class/object (ADTs) Part 4 — apply & unapply functions Part 5 — implicits <- you’re here Having looked at case class and extractors recently, the next logical thing would be partial functions. Since Andrea pointed me to a really well article on the subject I don’t think …
Read the whole series: Part 1 — type inference Part 2 — traits Part 3 — case class/object (ADTs) Part 4 — apply & unapply functions <- you’re here Part 5 — implicits Last time around we looked at Scala’s Case Class in depth and how it compares to F#’s Discriminated Unions. F# also has Active Patterns, which is a very powerful language …
Read the whole series: Part 1 – type inference Part 2 – traits Part 3 – case class/object (ADTs) <- you’re here Part 4 – apply & unapply functions Part 5 – implicits Continuing on from where we left off with traits last time around, let’s look at Scala’s case class/object which can be used to create Algebraic Data …
Read the whole series: Part 1 — type inference Part 2 — traits <- you’re here Part 3 — case class/object (ADTs) Part 4 — apply & unapply functions Part 5 — implicits Continuing on from where we left off with type inference last time around, let’s look at a language feature in Scala that doesn’t exist in F# – traits. Scala has …
Read the whole series: Part 1 – type inference <- you’re here Part 2 – traits Part 3 – case class/object (ADTs) Part 4 – apply & unapply functions Part 5 – implicits It’s a new year, a new job, a new language (Scala) and runtime (JVM) to work with. After a week of learning …
ps. look out for all my other solutions for Advent of Code challenges here. Day 25 See details of the challenge here. Today’s input looks like this: cpy a d cpy 7 c cpy 362 b inc d dec b jnz b -2 … At last, we’re at the end of this year’s Advent of …
ps. look out for all my other solutions for Advent of Code challenges here. Day 24 See details of the challenge here. Today’s challenge is a mix of Breadth-First Search (or Level Order Tree Traversal) and the Travelling Salesman Problem. First, let’s parse the input file into a 2D array to make it easier for …
