Once I started playing with Docker on Windows it quickly turned out that latest version heavily rely on WSL 2, in comparison to an older Hyper-V based approach. One thing that changed significantly during this technology transition was lack of a setting screen to actually define the location (and other params), where the containers and downloaded images should be stored. As the space they occupy grows really fast and default is not always the best place for it!
Read more →As an iOS developer you often hear about dependencies management. Looking into this subject deeper quickly leads towards CocoaPods and Carthage as two very popular solutions, yet build with totally different mindsets and assumptions. First one is a centralized solution, with full list of existing potential dependencies, while the latter one simply downloads the GitHub repo locally and builds it or only references the prepared binaries.
And even if I like and used Carthage in my previous projects, I had to put it on hold for some time, because of its lack of support of XCFrameworks and in general the Xcode 12 style of development.
Read more →It bothered me for a very long time since I fixed my PC - why is StarCraft 2 so slow on Gainward GTX570? I remembered this card to be kinda good. And my suspicious about something being wrong with my setup escalated quickly when I found an older Gainward GTX275, which was performing astonishingly better than the current one. Yes - smooth Medium with 30fps is still far better than Very Low and 12-15fps.
Read more →You have probably heard already a tremendous number of times that unit-testing your Android code is important. It’s all true and still valid. And there is one recipe I tend to forget quite often, which I also found extremely useful, while writing tests exercising (or relying onto) any external data.
In this scenario, all the content is kept outside of the unit-test itself and is simply read at runtime from resources (aka assets).
Read more →Sometimes knowing the current version of Xcode used to build the stuff from command line becomes a useful intel. Here is the recipe on how to obtain this information in a clean manner. Easiest command would be to call:
$ xcodebuild -version That produces output like:
Xcode 12.5 Build version 12E262 As an improvement I could use sed to simply extract the number from a line with the Xcode prefix:

$ xcodebuild -resultBundlePath "$test_results_path" -workspace "$workspace_path" -scheme "$scheme_name" -sdk "$sdk_version" -destination '$destination' -testPlan "$plan_name" -only-testing:'$single_test_path' test Where:
test_results_path - describes the path, where to store test outcomes (.
Read more →This time it won’t be a guide I came up myself from scratch. Recently I joined a totally new Swift project and wanted to quickly understand, what it does. Then I had an idea of navigating and finding issues, that were left there by my fellow previous developers. Those specially marked lines are usually left there and aren’t meant to be brought to light. Mentally they can be ignored for years by their creators.
Read more →Things has been simplified over time and my old guide about Git Commands has been improved a bit. At least in the context of removing remote branches. Now, it’s as easy as passing --delete parameter along with pushing changes to the server.
git push origin --delete <remote_branch_name> Response will look like following:
To github.com:phofman/xyz_project.git - [deleted] <remote_branch_name> What is even more beautiful in this syntax is that it also works for remote tags!
Read more →Finally, at some point in application development cycle there is a need to test it on a big screen. Four months ago we started playing with Philips 55PUS7502/12. Big enough to see all the details. So how to get started?
Press Settings on the remote and navigate to Settings > All settings > Android Settings.
Open System Information.
Click 7 times on Compilation version.
Read more →Another task on the horizon: integrate OpenCV 3.4.9 into an Android application written in Kotlin. Additional requirement complicated this task a bit. Let’s also try to have some C++ code around, that is shared with other platforms and that interacts and configures OpenCV video processing. Of course nobody expects any rough edges nor problems, right…
One might think it’s a typical scenario and lots of mobile apps use OpenCV this way.
