Knowing where the problem lies is only a half-success. The other half is having the knowledge to fix it. Recently our colleague Adam was tasked with getting to the bottom of an issue in one part of a system we were developing for a client. It required quite a bit of detective work, some experimentation, and ultimately learning. Here's the story of his journey.
It’s great to see the experts in all fields taking their events online over the past few weeks. There are plenty of excellent events out there, with new ones popping up every day. We gathered a list of some upcoming online-events below. We hope you find it beneficial!
In part one of this series we introduced the concept of hypothesis testing, and described the different elements that go into using the various tests. It ended with a cheat-sheet to help you choose which test to use based on the kind of data you’re testing. In this second post we will go into more detail on proportion-based samples.
The inaugural DataViz Live was held in London in late February this year, and we hopped on a plane to London to absorb everything we could from the experts. We attended a good mix of talks and want to share some of our learnings with you.
We’ve certainly found JHipster to be very useful for certain types of projects but found that we needed to add multi-tenancy support to the JHipster applications on more than one occasion. With that in mind, and given that multi-tenancy is quite a common requirement for us, we took the opportunity to learn more about JHipster Blueprints and developed our own for creating multi-tenant applications.
Network congestion is a widespread problem for telcos. Most of them rely on the guesswork of experienced operators and to our knowledge a completely automated solution does not exist. This post focuses on our recent developments in the area of predicting mobile network congestion, with the aim to prevent service degradation.
From building a data analytics team to choosing the right UX tool, let’s reflect on our most popular articles of 2019.
Back in November I, along with some other Sonalakers, attended FrontEnd Con in Warsaw. The speaker lineup was impressive, with some very well known industry names in attendance, and an agenda with no filler. After the conference, we got back together at SonalakeHQ to reflect on our biggest takeaways from the two days.
We want to help users make decisions when looking at data. Sometimes though it’s too expensive to check all of it or it’s so complicated that you can be led into taking the wrong decision by making an assumption about it. In cases like this, hypothesis testing can help us by giving us a degree of confidence that either our observations are real, or the changes we’ve made have, in fact, made a difference.
We were delighted to host the November Java User Group (or JUG) meetup in our Poznan office. This was our second time hosting and we had a fantastic attendance, with over 120 tickets distributed.
