Hey ho đź‘‹

I’m Lukasz and here I irregularly collect thoughts of mine, that I wanted to capture for one reason or another. Want to know more about me?

A change / next step

Back in 2013, I was building a system to help with pediatric kidney transplant research while also trying to write a PhD at the same time. That split did not work out. I liked building the system and the team around it way more than writing papers and the dissertation work itself. Still, it took me a while though to actually acknowledge that. To allow myself to say: I like the one thing more than the original goal....

Java Frameworks in 2020 ?

Java/JVM ecosystem is extremely mature and vast. It comes with a palette of production-ready choices for libraries solving problems that we face developing all kinds of services: be it from logging/metrics to async messaging or access to all the major sql and nosql data stores. Add the big talent pool (Java is very often used as the programming language used during CS-courses)[1] and it’s no wonder that this particular language and ecosystem is on the top or among the top 5 in the programming language statistics [2][3]....

My first UHK layout

I ordered the UHK with the linux layout as I thought that I will be moving towards a linux laptop as the main driver for my work. Somehow this didn’t happen :confused: and therefore I ended up using the UHK with a Mackbook Pro. Thus, I changed few settings and love my setup even more. UHK is really a spectacular keyboard. I quickly decided to just align the Fn, Ctrl, Option and Cmd key with the mac layout so that my mussle memory doesn’t suffer too much....

Using your yubikey as ssh key provider / Quick(est) guide

I figured it’s time to write up the quickest guide about using the yubikey as the source of your ssh key. This assumes that: You have a yubikey and it’s in your usb port You’ve configured gpg on you machine (I’m running gpg (GnuPG) 2.2.7) You’re using the gpg-agent with enabled ssh support Here are the steps: gpg --card-edit > admin > generate > [enter the requested PIN] > quit And now you’re done....

why hugo?

As you can see looking at the frequency of my posts, I’m more of an occasional writer. Therefore whenever I drag myself in front of my notebook, to write something up I’m feeling like sharing, I should really not have any reason to do something else instead. Sadly, although I was really happy with my octopress setup, more than once I found myself fighting the currently installed ruby versions and some conflicts with the gems that octopress was requiring....

bff

A while ago I wrote a ThoughtWorks insights post about the Backends for frontends pattern and the story behind its adaption at SoundCloud. It generated interesting discussions and resulted also in some further content and I thought it would be good to have a place with links to all this resources for the future reference. BFF @ SoundCloud - the original post talking about the pattern and journey towards it BFF pattern definition - comprehensive pattern definition Moving to Microservices at SoundCloud - Software Engineering Daily podcast - a podcast talking about microservices in gerneral, SoundCloud’s journey towards this style of architecture and usage of BFFs BFF @ SoundCloud (podcast) - an interview about UI composition in a microservices world in general and the BFF pattern

express testing

After we managed to set up our basic web application, let’s get our hands dirty writing some code. And as we want to do it in a test-driven manner (TDD), we need a proper test setup. This piece is all about our initial test pyramid. Test, what? Yes, pyramid: At the base of the test automation pyramid is unit testing. Unit testing should be the foundation of a solid test automation strategy and as such represents the largest part of the pyramid....

bootstraping a node.js webapp

Together with few friends we started building pace - a web application for organizing and managing running events & competitions. We are a colorful bunch of people with different backgrounds, therefore we wanted to choose an approachable tech stack, as some of us wants also to learn one or two things about JavaScript, web applications or programming in general. And then, somebody suggested to write one thing or two, about our technology decisions and accompany it with some HowTo information....

build monitors

During my last four projects or so, the teams I worked with were always using GO.CD as the CD tool of their choosing. Although the pipeline state visualisation GO.CD comes with is quite nice, it still doesn’t cut it as a proper, obvious build monitor enabling everybody in the team to quickly recognize what is the pipeline status. Burstah in action Therefore first cidar, a simple sinatra based build monitor, has been born....

scoopcamp hackathon

Last Thursday I was a part of the Scoopcamp hackathon and it was so great that I just couldn’t resist to write down some of my thoughts about it. Our team ThoughtWorks and friends a colorful mix of journalists, students and developers had a rough idea for a modern - more agile - journalism, where the journalist reporting about an ongoing event writes the background story and live updates from his perspective, but can also incorporate content written by the readers who create their own streams representing their own take on the particular event....
