Black Box Puzzles is one of few websites that actually can help you become better tester.
On centenary of Polish independence, I noticed that my spendings on rogale świętomarcińskie (St. Martin Croissants) follow peculiar pattern.
I grabbed a list of blogs aggregated on Association for Software Testing website, so you don't have to.
Mark Blyth is economist-turned-political scientist that you should definitely check out.
This is software release announcement disguised as impressions on pop culture phenomena.
Head on to Michael Bolton blog to read about fundamentals of Rapid Software Testing.
Testerzy.pl, one of the biggest websites for testers in Poland, published short article about problems with system behind SAF-T. It's in Polish, but Google Translate does not-terrible job at translating it to English. The bottom line is: application does not allow to input numbers with more than two significant digits. Testerzy.pl claim that system was "not tested enough".
Luke Oakden-Rayner, PhD candidate in field of radiology, explains why certain X-ray images database is not really fit to task of training medical systems to do diagnostics. His observations stem from questions that apply to pretty much any dataset used to train machines.
Yesterday, I tried to register for TestingCup competition and conference. Number of issues I have encountered is well outside of my comfort zone.
Last week I have written about automated translation system gone awry in the midst of Polish international relations crisis. Today I have discovered extremely good article explaining important parts of artificial intelligence in layman's terms.
In the middle of Polish international relations crisis, we can see why robots won't take our jobs anytime soon.
This is supposed to be tech-oriented blog, but since I rarely write anything anyway, let's talk about Star Wars instead. Spoilers ahead.
Protractor is test framework for web applications written on top of Angular. Unfortunately, installing it on Debian is non-obvious, as it has not yet found its way into repository and existing documentation is catered to needs of Mac OS users. This guide will help you to get through this process without messing up your entire system.
StackOverflow user seakyourpeak asked if R can be used to verify whether given string is a word in English or not. This is interesting problem that gives us opportunity to explore different kinds of correctness.
97 years ago Poland regained independence after being partitioned for well over a century. The date coincidences with St. Martin Day, a holiday with pagan roots that somehow managed to be more important here in Poznań. We celebrate by having a parade on one of main streets and eating ungodly amounts of rogal świętomarciński (St. Martin Croissant), a local cake with PGI status in European Union. In this blog post I will show how to plot locations of bakeries that are allowed to sell products with that name.
Reddit user alignedletters asked how to read data stored in custom format into Microsoft Excel. The problem was twofold - each record was represented by two lines, there was no clear delimiter between fields and one of issues mentioned so far is actually more complicated than that. In this post, I show how that data can be read in R.
One day I was wondering whether anyone actually reads that blog. A thought about setting up Google Analytics crossed my mind, but legitimate concerns about users privacy made me hesitant. Then I wanted to try out Piwik, but installation and configuration requires some effort and I wasn't sure if I want to make that investment. Eventually I figured out that I should probably do whatever other R and python bloggers are doing. But first I had to learn what it is.
The other day I was trying to fetch some data from XML file using R package
xml_find_one function kept returning
Error: No matches. Here's what was wrong, why it was wrong and how to fix it.
Every now and then I stumble upon book that disguises itself as website - it has table of contents and spans multiple interlinked pages, each dedicated to one coherent piece. Sometimes I like to take them offline, so I can read them on travel. Sometimes I like to take them off computer, because reading long passages of text on screen is not that convenient. Sometimes I would prefer to have them in ebook format, because that's what they really are. Here's how I do that.
Earlier this year, bad PR stunt by SourceForge caused many users to reevaluate their relationship with website. Recently, Google turned Google Code to read-only mode, with promise to pull the plug completely in foreseeable future. Source code hosting services landscape changed immensely, with GitHub being about the only major player left. There are reasons to not be happy with that situation. Hopefully, you will keep them in mind the next time you wonder where to host your new open source project.
