The best way to keep the VM responsive is to take a page from Gauss' notebook and pay attention to the numbers[1]. Let's consider the first four squares and extrapolate from there. In binary, the squares hold the following grains: 2r1, 2r10, r2100, and 2r1000. When we add them up, we get 2r1111. If we use Gauss' tricks, we can notice that 2r1111 is equal to 2r10000 - 1. So, the sum of the grains on the first 4 squares is 2^5 - 1. You can easily generalize that pattern, of course. Then your program can calculate the answer quickly. [1] The story goes that Gauss' teacher was frustrated with his student's abilities and set him a challenge to occupy him for some time: sum the numbers from 1 through 100. Gauss immediately answered 5,050, much to his teacher's chagrin. > Regards, > > Roelof > > >

You can wrap the whole thing in a block and execute it in the background. Look for uses of fork: or forkAt: Joachim > Am 04.01.2020 um 18:46 schrieb Roelof Wobben via Pharo-users <pharo-users(a)lists.pharo.org>: > > <mime-attachment>

can I make this so the vm would not be not responsibe when running the tests

by Roelof Wobben

Hello, For a exercism challenge I need to calculate the total grains on a chessboard. So I did : atSquare: anInteger Â Â Â self validateInput: anInteger. Â Â Â ^ anInteger = 1 Â Â Â Â Â Â ifTrue: [ 1 ] Â Â Â Â Â Â ifFalse: [ 2 * (self atSquare: anInteger - 1) ] but when I run the tests , the vm seems to be not responsive for some 4 - 5 seconds. Is there a way I can use this code and take care that the vm stays responsive. Regards, Roelof

Yes, I added it by using localhost:8080/config and then choose for the application. In the tutorial Im following that was the way the application is registered and the library. So where should I add the code you are saying to use.
