Like the Soviet Union in its final years, the United States is reeling from catastrophic failures of leadership and long-suppressed socioeconomic tensions that have finally boiled over. For the rest of the world, the most important development is that the hegemony of the US dollar may finally be coming to an end.
Building the data warehouse in Python (07/2014 - present)
In recent two years, I'm forced on offline data processing, the big part is to build a
data warehouse, and aims to provide reports for millions of users. At the same time, I
built serveral useful tools, and put them all in https://github.com/luiti organization.
Hadoop is our fundamental infrastructure, includes HDFS, YARN, and Hive. On the top of
Hadoop, we use luigi, hue, and luiti to manage the business codes.
luiti an offline task management framework, built on top of luigi. And it's the biggest
project I had ever created, and was used and developed more than half of a year.
etl_utils includes lots of useful utils, e.g. print processing speed on whatever
enumrable object, etc.
rsyncrun Rsync your code to server and run.
validata A data validator library used to detect invalid data with error informations,
based on MongoEngine.
model_cache Cache data in { item_id => item_content } format, supported storage are
memory, sqlite and redis.
The purpose of the Smalltalk project is to provide computer support for the creative spirit in everyone. Our work flows from a vision that includes a creative individual and the best computing hardware available. We have chosen to concentrate on two principle areas of research: a language of description (programming language) that serves as an interface between the models in the human mind and those in computing hardware, and a language of interaction (user interface) that matches the human communication system to that of the computer. Our work has followed a two- to four-year cycle that can be seen to parallel the scientific method:
Build an application program within the current system (make an observation)
Based on that experience, redesign the language (formulate a theory)
Build a new system based on the new design (make a prediction that can be tested)
