I dream my painting, and then I paint my dream.

我梦见我的画,然后我画我的梦。

It was a long time after I had a good dream the last time.

I dreamed I was the lucky one who won the lottery, a lot of money.

I dreamed I was capable of dealing with everything well.

That were my dreams and that are the very things I want now.

It seems I should earn what I want through my own dedications, don't figure on those things out of my control.

When you play, play hard; when you work, don't play at all.

玩耍请尽兴,工作勿儿戏。

From Theodore Roosevelt.

Today I tried to compile the ROS-Kinetic for Raspberry Pi 3b with Raspbian.

And I set a deadline for this job, that was today.

Following the instructions in the tutorials, the preparation for the compilation went quite smoothly, despite several trivial revisions to the tutorials according to the environment of my operating system.

And the biggest problem I encountered during the pre-compilation was to download the package of opencv3 from the address provided by the install-script.

Actually it may be not a problem if there was no firewall in my network.

However, during the compilation, I found it was very slow due to the hardwares in the platform.

The computing power and the memory were not enough to process such big program.

When the compiler built opencv3, it seemed the memory was exhausted.

So I had to disrupt the compilation and postpone the task to tomorrow.

The result was not satisfying, but I still got something that I had ignored before.
