Finally Got RESTful

REST is a web-site architecture paradigm. One that's used in Rails and that for the longest time seemed to involve some mumbo-jumbo. But it's way simpler than I originally thought, but also easy to confuse.

So what is REST? REST stands for Representational State Transfer.

But basically what this means is that instead of there being a digital asset in a location all there is a representation of that digital asset. Or in other words instead of finding a file in a particular location, all there is is a file-path-location that is interpreted as a command for a digital asset that lies elsewhere. This has two consequences: the file you are seeking does't have to exist, the Rails server can create it ad hoc, and you don't have to go to one page to view an asset and another page to modify it. The server can interpret different commands along with the path as a way of manipulating that asset.

How REST works is kinda besides the point. I already got that, but not why it did what it did. Now that gives you insight into it. The rest is part of the Rails magic and how it translates requests for locations with the web protocols of GET, POST, DELETE and PUT, into commands Rails understands.

What Medieval Economics can teach us about tariffs.

As a teen, I used to play Dungeons and Dragons (D&D) with my friends. This started an interest in the medieval period that led to me taking a medieval history class in college just to understand the period more. Over the years I've also read great books like " Dungeon, Fire and Sword " about the crusades (I recommend the book) and yet with all that knowledge it wasn't until recently that it occurred to me I had a completely wrong understanding of economics in the Medieval Period. "Viking helmets, sword and footwear" by eltpics is licensed under CC BY-NC 2.0 In my D&D games, players who are adventures battling monsters and creatures would need equipment and on the trips to town, they'd get resupplied with their adventuring necessities. I'd run these moments referencing my imagination of what it must have been and fantasy books I'd read. There be an inn with a raucous bar, a gruffly black-smith, if a city also a weapon and armor sm...

Multiple Assignments in Ruby

In this Rails project I'm running I need to set a whole bunch of individual variables to 'disabled' at once depending on the group the current user belongs to. We can use multiple assignment in this case but with a caveat. Multiple assignments are a quick way of setting a lot of variables at once. h, k = 1,2  => [1,2] h => 1 k => 2 but   h, k = 1      => 1 h => 1 k => nil In that case we can do this: h = k = 1   => 1 h => 1 h => 1  Beware this sets them to the same object. So if you change one you change both. h = k = [] h << 1 h => [1] k => [1] While we're at it here is how to reverse two variables: h = 1 k = 2 h,k = k,h h => 2 k => 1

Best Tech Books

Best Tech Books for Programming Language Learning I'm a bit of a polyglot no only in human languages (English, Spanish, Japanese) but also with programming languages. I found that the best way to get a deep understanding of the programming field, I needed to be broad. I got introduced to Bruce Tate's 7 languages in 7 weeks series right when I was starting to learn Ruby and found the cross-language trends to be very useful in knowing what to learn for the future.  So here is a list of Programming Books that I found good for learning a language. These are the must have books in my opinion to "get" or "grok" the language. Most of these books I have not finished but they're so good I can recommend them for other language learners and polyglots. All these books should accelerate your learning dramatically.  Poignant Guide to Ruby Ruby: POODR and _why's Poignant Guide to Ruby .  Okay, so _why's Poignant Guide to Ruby is the reason I fell in love with ...
