Do odważnych świat należy [DSP2017 #01]

Witam wszystkich uczestników ;)

Od jakiegoś czasu chodziło mi po głowie założenie bloga niestety nie miałem do tego wystarczającej motywacji. Wtedy wpadł mi w ręce artykuł zachęcający do wzięcia udziału w DSP 2017. Myślę, że jest to fantastyczna okazja na powstanie (od dawna planowanego) projektu oraz spróbowania własnych sił w tworzeniu bloga :)

Projekt "Nany"
Celem projektu jest stworzenie aplikacji zbierającej dźwięk z pokoju dziecka. W momencie wykrycia dźwięku system powinien informować rodziców o zaistniałej sytuacji. Projekt prowadzony będzie w metodologii Agile, a o wszystkich rezultatach oraz zmianach będę informował na blogu.

Technologie:

Python – aplikacja do zbierania dźwięku i wysyłania sygnału do serwera,

Java – implementacja serwera aplikacji.

Types of tests [DSP2017 #04]

As a java developer with more than 3 years of experience I had opportunity of participating in few projects. To be honest only in a last one a testing strategy is on high level. I encourage you for introduce and put more pressure on testing strategy during a delivery process. As with all new things the beginnings are difficult but I'm sure that it is worth. As almost testers know undermentioned pyramid I need to put it for people who have not seen it. In a big amount of projects we can meet this pyramid in inverted order. What can impact of quality of a system. For example when we have a lot of manual tests it is boring for users and sometimes they can be skipped what can missed bug. So in the lowest level we see the Unit tests and the count of this should be the bigger and on the highest level, there are manual tests. As we can expect the count should of them should be the lowest. A few words about each of them: Unit tests - should be quick and small. They check jus...

Oracle Certified Associate Java SE 8 Programmer I: Exam 1Z0-808 [DSP2017 #05]

Hello and sorry for absence during last weeks. This time was very busy because I had to prepare myself for OCA certification. In this post I want to write few word about: what I've done how it looks what I will improve next time I've read one book from beginning to the end. It was OCA Java SE 8 Programmer I Certification Guide MALA GUPTA I think that it is good book for gain knowledge about base java. There is a lot of examples, very detail description. Form point of exam just reading and making the tests is not enough. The test inside this book are not so easy but they don't cover real exam. Next books which were only source of mock tests: OCA / OCP Java SE 8 Programmer Practice Tests OCA: Oracle Certified Associate Java SE 8 Programmer I Study Guide: Exam 1Z0-808 The mocks in the first position are very easy and so short. In real exam the examples of code was so longer and requires more concentration. During the preparation I was...

How to start with Android development [DSP2017 #07]

In this part I want to show how I started with a first app. My previous experience with creating an Android application was about 4-5 years ago. I've created one or two simple applications during my studies and forgot about this topic. Today when I wanted to create a new app I needed to start from beginning. First of all I need to install tools: Android Studio (I use Intellij with Android extension). Android SDK - I used the sdkmanager but during Android Studio installation sdk should be installed. If you have 64 bits system you need to check: Required libraries for 64-bit machines . If you have installed all above tools you should be able to create simple Android project and run it on your phone. Yes, like always I met few problems with run the application on my phone. #1 The adb can not find my device. Solution : turn phone as MTP mode. 2# Error:Execution failed for task ':app:processDebugResources'. > com.android.ide.common.process.ProcessException:...
