Re: [Rails-core] basE91 in Rails
Hello, There is no evidence that it is being used a lot. But there is this, https://www.npmjs.com/package/base91 ( 100 downloads till now). And this, a research paper, http://www.iiis.org/CDs2010/CD2010SCI/CCCT_2010/PapersPdf/TB100QM.pdf Seems pretty interesting. there is 7.7% (of Base64’s encoded data) cut off in data traffic, transfer time, transfer cost, at the same time there is saving our society some energy, if employing Base91 instead of Base64 as encoding for network data transfer with huge data We never know how much of a performance boost it provides or what downsides this has, unless we try it out ourselves. Let me know what you guys think.

Instead of adding this directly to Rails, why don't you create a gem that adds support for this encoding? Many of the features we use today (strong_params, turbolinks, ARel...) started this way, and it’s worked fine so far (it allows us to test features without adding extra complexity/impacting a large number of users). -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Core group.

Re: [Rails-core] basE91 in Rails
Hello Federico, Seems like a good first step. But I just want to get a general idea, if this is something that the developers will use at all ? ᐧ On Mon, Mar 9, 2015 at 10:58 AM, Federico Builes federico.bui...@gmail.com wrote: Hi Sushruth, On Mar 8, 2015, at 11:00 PM, Sushruth Sivaramakrishnan sivsushr...@gmail.com wrote: There is no evidence that it is being used a lot.

Re: [Rails-core] How does ActiveRecord::TestFixtures::ClassMethods#run_in_transaction? work?
On Mar 6, 2015, at 12:59 AM, Brandon Weiss bran...@anti-pattern.com wrote: Here's the method: def run_in_transaction? use_transactional_fixtures !self.class.uses_transaction?(method_name) end I'm super confused. What is `method_name`? And where does it come from? It's not a local variable. I can find two instances of `def method_name` in the repo and neither seem to be related. If I try to call the method directly and `use_transactional_fixtures` is false I get `NameError: undefined local variable or method `method_name'`. How is this working normally? `ActiveRecord::TestFixtures` is mixed into the test case class itself. `method_name` is an alias for the `Test::Unit::TestCase#name` method, which the test harness sets up every time an individual test is started up. The data maintained by `uses_transaction?` and friends is used to tell the fixture system that a particular test uses transactions internally (after_commit hooks, etc) and therefore *shouldn’t* be wrapped with a transaction. You’d specify this by saying `uses_transaction :name_of_test_that_uses_transactions` in your test case. —Matt Jones -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Core group.
