Humble Chronicles: Managing State with Signals
After the previous post, I figured that the best way to decide on the direction for Humble UI is to make an experiment.
And I did. I implemented a reactive/incremental computation engine (signals) and wrote a simple TodoMVC in it. Following are my thoughts on it.

GIMP Tutorial: Colorizing A Black & White Photo
On YouTube, I have found several tutorials for colorizing a photo. Michael Davies Design has one, as well as Logos By Nick and others. I also found one by JBColourisation. I also did an article on colorizing a photo back in 2013, but there are several methods, so we'll do a different method this time.
We'll be using layer masks for this, and I just heard an easier description of a layer mask. It's like "a window that's been blacked out" so you can't see what's inside, and when you paint the layer mask, you're "making a hole" that shows what you want seen.

GIMP Tip: Join Text
When I first registered for PCLinuxOS and started getting more involved in the community, I noticed how in the artwork of the distro logo, two letters in the middle are cleverly 'joined' to look like only one letter or character. The U and the N look like they are merged or magically melted together. Being a fan of graphics, in time when I needed to use the logo, I wasn't sure how to go about joining the two letters. I asked in the forum, but the answers I got didn't yield a good enough result. There was always something sticking out of place, or something didn't look quite right. In time, I eventually figured out how to join the two letters seamlessly. Here, in this Gimp tip, we'll see how I made it work for me. I am sure there are many other different ways to accomplish the same task, but this is how I do it. (See samples A1, A2, A3)
