Once you start trying to add complex functionality–such as HTTP communication between different applications–you will often find yourself working in well-defined problem domains that have well-known solutions.
So while it might be a good learning exercise to write your own solution to one of these problems, ultimately your application would be best served by using one of these pre-existing solutions.
You can then ensure that your code operates with a common interface that matches community development standards.
Thanks for following along with this how to: Adding Ruby Gems and Gem Sources.
Please note, we are currently updating the 2018 Journal Metrics.
GEM – The International Journal on Geomathematics publishes peer-reviewed mathematical papers that deal with (i) modelling of the system Earth (geosphere, cryosphere, hydrosphere, atmosphere, biosphere) (ii) analytic, algebraic, and operator-theoretic methods, (iii) computational and numerical analysis methods necessary for the mathematical treatment of geoscientifically relevant problems, and (iv) survey articles bridging Geosciences and Mathematics.
This requires a little bit of work: applications should be called with Quarry is an opensource tool (GPL3 license) that allows to maintain rubygems binary repository for Arch Linux, as an easier alternative to building packages manually from the AUR. The repository is maintained by Arch developer anatolik at and is currently for the x86_64 architecture only.
It contains many popular gems and new gems can be added upon request.
You can mitigate this issue by encapsulating the code into separate classes–which solves the reuse problem–but this solution only scales to a certain point.
Mathematics concerned with geoscientific problems, i..e., geomathematics, is becoming increasingly important, as first, modern high speed computers and satellite based techniques are entering more and more all geodisciplines, and secondly a growing public concern about the future of our planet exists, its climate, its environment and about an expected shortage of natural resources.
Efficient strategies of protection against threats of a changing Earth and the exceptional situation of getting terrestrial, airborne as well as spaceborne data of better and better quality explain the strong need of new mathematical structures, tools and methods to be published, for which GEM serves as adequate forum.
Figuring out which gems are currently installed on your machine can be daunting, and in a worst-case scenario would involve navigating to the RVM install directory for your current version.
Luckily, we have access to Sometimes a gem outlives its usefulness, or it is superseded by a superior alternative.
