Moving to Canada (2)

This is one out of three blog posts I’ve planned for my immigration to Canada. This post will primarily be about my dog Yumi and how he relocated to Canada with us. Yumi was born September 8th 2015 - by the time we travelled he was close to his 2nd birthday. We did plenty of research to make sure that his immigration went as smooth as possible. First, we had to organize a properly sized transport box for the flight, and secondly comply with the Canadian dog import regulations. Read more

Moving to Canada (1)

As mentioned earlier 2017 will be a hectic year - I’m looking forward to immigrating to Canada. I’ll be relocating to Vancouver, British Columbia, to start working at Amazon. Living abroad and working at one of the big five tech companies (Amazon, Apple, Google, Microsoft, Facebook) have been two of my goals for a long time, and both will be reality end of August. I can’t articulate how excited I am - it’s a huge opportunity to growth for me, and it puts me well outside of my comfort zone. Read more

Modifying binaries to replace proprietary APIs

Note This is a follow up post on exploring private apis from late May. Soon I want to use the Things 3 macOS application with my own API. To achieve this goal I have built a working SDK for the things cloud to understand the structure of the communication between client and server. This time I want to modify my Things 3 binary so it actually talks to an API of my choice. Read more

Moving Forward

Everything changes and nothing stands still. Heraclitus And 2017 will be quite a hectic year for me because of this. I’m looking forward to sharing more non-technical things in the next few months, too. Mostly pictures I guess, but we’ll see what I’ll find interesting enough to share (:

Exploring private HTTPS apis

Today I want to take a look at how you can explore private HTTPS APIs. I’ll be using @culturedcode Things Cloud as an example: it’s the main engine behind keeping Things for iOS and Things for macOS in sync, and as there is no web version available it’s a little more tricky to take a peek behind the scenes. First off some requirements: you need to be running macOS for this to work, and you need a Things 3 installation along with a thingscloud account. Read more

Awesome AWS CodePipeline CI

After several talks at work about the feasibility of using AWS Codebuild and AWS Codepipeline to verify the integrity of our codebase, I decided to give it a try. We use pull-requests and branching extensively, so one requirement is that we can dynamically pickup branches other than the master branch. AWS Codepipeline only works on a single branch out of the box, so I decided to use Githubs webhooks, AWS APIGateway and AWS Lambda to dynamically support multiple branches: Read more

Running your own ZNC bouncer

Over the holidays I decided to get ride of the Slack Desktop application, one very RAM hungry application I’m using constantly. Moving to the browser client is no option as I have way too many tabs open in all browsers you could imagine. As I’m constantly using the terminal I decided to replace the Slack Desktop application with a command-line interface IRC client, irssi. Now irssi works great with Slack via Slacks IRC gateway, but I wanted to receive messages while I was offline, too. Read more

Response times percentiles from opentracing

At work we have started using opentracing with a zipkin backend and elasticsearch as storage layer. Zipkin creates per-day indices inside elasticsearch, meaning we can use the raw data to generate correct response time percentiles for individual services grouped by date. After an initial draft which used a HdrHistogram on the client side Zachary Tong, an employee, suggested on twitter to use the build-in HdrHistogram in elasticsearch instead. The resulting code is a little shorter, and runs much faster due to the fact that we cut down the amount of data needed to be transfered. Read more

Scaleway on terraform: remote-exec provisioners

In this blog post I want to explore two options of using terraform and the remote-exec provisioner with the new Scaleway cloud provider. using Scaleway First, signup for Scaleway. Once you have a Scaleway account, export the required credentials to your environment like this: export SCALEWAY_ACCESS_KEY=<your-access-key> export SCALEWAY_ORGANIZATION=<your-organization-id> You can find out both information easily by using the scw cli; it’ll write the information to the ~/.scwrc file. Now you can use the scaleway provider like this: Read more

Learning Erlang #1

after attending dotScale 2016 I finally got enough motivation to properly start learning Erlang. From past experience I know that I need a project to play around with while learning a new language. So I decided to work on an outstanding task for traq, my CLI time-tracking tool: a JSON API to use as a remote storage backend. While rsync (or dropbox, fwiw) would work great as a solid synchronization mechanism I want an API which allows me to write a mobile app for traq someday. Read more
