Jak uruchomić testy dla Javy pod NetBeans

 Generalnie NetBeans włącza biblioteki testowania z sygnaturą 5.****. Te biblioteki NIE DZIAŁAJĄ z Antem. 

https://stackoverflow.com/questions/54161715/netbeans-10-junit-jar-not-found

I'm running netbeans 10 as well, in xubuntu if that helps. I have no idea what is going on, so I had to revert to junit4. EDIT: To be perfectly clear, ant needs junit.jar which is nowhere to be found in the default netbeans 10 installation. Until someone brings a better solution, revert to junit4:

1) in your test libraries, right click and import the junit 4.1.2 ones.

2) remove the junit 5.3 ones.

3) scrap all the imports in your test file and use the junit4 ones. ie your imports will look like:

import static junit.framework.Assert.assertEquals;
import org.junit.Test;
import org.junit.*;
/*import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.Test;*/

4) scrap the beforeAll and other test tags. Only leave the @Test one.

5) save all, close and re-open the project. It will complain that the hamcrest libraries for junit4 are not imported. Allow netbeans to fix it for you.

With that done, I was able to test successful and failing tests. I guess when you generate the junit tests with the template generator, it will generate the junit5 ones, so, a bit annoying. But you'll have tests!

calendar disappeared from thunderbird

Ubuntu 16.04. Thunderbird 60.2.1 (64 bits) Calendar has disappeared.

That change in Thunderbird, which is automatically updated, costed me 1 hour of research and work. How many hours these guys took from ppl around the world? Is seems they just don't care. Because, maybe, they become big.

For now: 
1. Remove Lighting from Thunderbird.
2. Close Thunderbird
3. sudo apt install xul-ext-lightning
4. Start Thunderbird again.

Calendar is here again.

Or... you may try to download and install appropriate version of Lighting:
- versions: https://developer.mozilla.org/en-US/docs/Mozilla/Calendar/Calendar_Versions#Stable_Releases
- downloads: https://ftp.mozilla.org/pub/calendar/lightning/candidates/

For tomorrow, seriously consider different pim tool, because you may find yourself in not comfortable situation.

Idea: This is a search graph task. A used this explanation of the algorithm LINK.

In first step you check all possible single jumps from start point. This creates a new "row" of starting positions.
In next step you check all possible single jumps from every start position in the "row".
Sum of found new positions create another row.
You skip if you find a possible jump to the position which was "visited" previously, because there is a shorter or equal path to that position.
You stop when any jump will reach "end position" or you cant find a position to jump anymore. Code:
