Tips about drawing digitally

I asked on https://www.facebook.com/groups/1014974001864957/permalink/1252338398128515/ and these were the main points:

Set the tablet settings, on the driver and on the software used for drawing. For example, pressure sensitivity.
Check the projection: what screen you're using to project the table and ensure the "constrain proportions" setting is checked.
Consider line stabilizing software like Lazy Nezumi Pro (only Windows so far). Sketchbook Pro has this sort of line as well.
Use Mischief rather than Photoshop for line drawing. It's simpler and produces more natural line drawing, which can be later exported for rendering in Photoshop.
Get comfortable with using undo constantly.
Use hard felt nibs for the tablet, the have increased friction and feel more like a pen on paper.

belongs_to:

Assigning an object to a belongs_to association does not automatically save the object. It does not save the associated object either.

has_one:

When you assign an object to a has_one association, that object is automatically saved (in order to update its foreign key).
In addition, any object being replaced is also automatically saved, because its foreign key will change too
If either of these saves fails due to validation errors, then the assignment statement returns false and the assignment itself is cancelled.
If the parent object (the one declaring the has_one association) is unsaved (that is, new_record? returns true) then the child objects are not saved. They will automatically when the parent object is saved.

As a global platform for creativity and self-expression, Tumblr is deeply committed to supporting and protecting freedom of speech. At the same time, we draw lines around a few narrowly defined but deeply important categories of content and behavior that jeopardize our users, threaten our infrastructure, and damage our community.

What Tumblr is for:

Tumblr celebrates creativity. We want you to express yourself freely and use Tumblr to reflect who you are, and what you love, think, and stand for. What Tumblr is not for:

Malicious Speech. Don't encourage violence or hatred on the basis of things like race, ethnic origin, religion, disability, gender, age, veteran status, or sexual orientation. We encourage you to dismantle negative speech through argument rather than censorship. We will, however, remove anything that is overtly malicious.
Harm to Minors. Be thoughtful when posting anything involving a minor. Don't post or solicit anything relating to minors that is sexually suggestive or violent. Don’

My job, explained so my mom can understand it

"I am a freelance Ruby and Rails developer". When I talk with my geek friends, everyone understands what I do and they have a reasonable understanding of how I spend my day. But sometimes, less technical people ask me what I do for a living and then I tend to dumb down the answer: "I am a programmer, I usually build websites.". Oh -they say- my nephew also make websites, he even built me a blog in Blogger.

Err... yes, but that hardly has anything to do with what I do for a living.

There are many different kinds of websites, built with different technologies, and depending on the site and the technology used to build it, they are made by one kind of professional or another. The craft of building a website comprises many different disciplines, and professionals usually specialize in just one part of the process. Although I do many different things, my specialization is mainly programming dynamic websites using Ruby and Rails.
