  • LIST of NOSQL DATABASES [Currently 150]
    Your Ultimate Guide to the Non - Relational Universe! [the best selected nosql link Archive in the web] ...never miss a conceptual article again... News Feed covering all changes here! NoSQL DEFINITION: Next Generation Databases mostly addressing some of the points: being non-relational, distributed, open-source and horizontally scalable. The original intention has been modern web-scale databases. The movement began early 2009 and is growing rapidly. Often more characteristics apply such as: schema-free, easy replication support, simple API, eventually consistent / BASE (not ACID), a huge amount of data and more. So the misleading term "nosql" (the community now translates it mostly with "not only sql") should be seen as an alias to something like the definition above. [based on 7 sources, 14 constructive feedback emails (thanks!) and 1 disliking comment . Agree / Disagree? Tell me so! By the way: this is a strong definition and it is out there here since 2009!] LIST OF NOSQL DATABASES [currently 150] Core NoSQL Systems: [Mostly originated out of a Web 2.0 need] Wide Column Store / Column Families Hadoop / HBase API: Java / any writer, Protocol: any write call, Query Method: MapReduce Java / any exec, Replication: HDFS Replication, Written in: Java, Concurrency: ?, Misc: Links: 3 Books [1, 2, 3] Cassandra massively scalable, partitioned row store, masterless architecture, linear scale performance, no single points of failure, read/write support across multiple data centers & cloud availability zones.

It also provides helpful tools to constrain or pin versions in recipes. Building a conda package requires installing conda-build and creating a conda recipe. You then use the conda build command to build the conda package from the conda recipe. You can build conda packages from a variety of source code projects, most notably Python. For help packing a Python project, see the Setuptools documentation. OPTIONAL: If you are planning to upload your packages to Anaconda Cloud, you will need an Anaconda Cloud account and client.

  • Luarocks Past, Present and Future
    LuaRocks past, present and future Hisham Muhammad Prologue: what is LuaRocks? ● A package manager for Lua modules ● Modules written in Lua (.lua), binary Lua modules (.so/.dll) and Lua scripts ● Usual features you would expect from a package manager ○ luarocks install <module> ○ luarocks remove <module> ○ ... Rocks and rockspecs ● Rock: a LuaRocks package ○ archive files (actually .zip files) ○ *.src.rock - contains source code ○ *.win32-x86.rock - “binary rock”, contains compiled binaries for a given platform ● Rockspec: a package specification file ○ A declarative Lua script, with rules on how to build and package rocks ○ *.rockspec - a Lua file containing some tables A rockspec Part I The past: a short history of LuaRocks Origins ● Kepler Project: research project to develop a platform for web development using Lua ○ combining modules that already existed (LuaSocket, CGILua) and adding the missing pieces ○ For more of the story, read Yuri Takhteyev’s book, “Coding Places” :) ● I started (re)writing Unix makefiles to automate the packaging/install process ● Common patterns emerged LuaRocks 0.x-1.x: a bumpy start ● 0.x was a gradual evolution ○ the goal for 1.0 was for it to be able to build all Kepler modules ● The rockspec format is unchanged since 1.0 ○ We really care about compatibility ○ Learning the format and writing a rockspec are not disposable efforts ● We got many things right, but we also got some of them wrong... Annoyances in LuaRocks 1.x ● LuaRocks 1.0 did not use the standard Lua layout for modules ○ It wasn’t clear that

  • An Efficient Algorithm for Type-Directed Structural Diffing
    An Efficient Algorithm for Type-Directed Structural Diffing VICTOR CACCIARI MIRALDO, Utrecht University, The Netherlands WOUTER SWIERSTRA, Utrecht University, The Netherlands Effectively computing the difference between two version of a source file has become an indispensable part of software development. The de facto standard tool used by most version control systems is the UNIX diff utility, that compares two files on a line-by-line basis without any regard forthe structure of the data stored in these files. This paper presents an alternative datatype generic algorithm for computing the difference between two values of any algebraic datatype. This algorithm maximizes sharing between the source and target trees, while still running in linear time. Finally, this paper demonstrates that by instantiating this algorithm to the Lua abstract syntax tree and mining the commit history of repositories found on GitHub, the resulting patches can often be merged automatically, even when existing technology has failed. Additional Key Words and Phrases: Generic Programming, diff, Version Control, Haskell 1 INTRODUCTION The UNIX diff [13] is an essential tool in modern software development. It has seen a number of use cases ever since it was created and lies at the heart of today’s Software Version Control Systems. Tools such as git, mercurial and darcs, that enable multiple developers to collaborate effectively, are all built around the UNIX diff utility, which is used to compute a patch between two versions of a file. It compares files on a line-by-line basis attempting to share as many lines as possible between the source and the destination files.
