bitcoin wallet is `1Nk9j9PwVVDL5sud6B3WcusjkJv2UirEtg` . Your donation
with product name will motivate me for sure. See my `Github
<https://github.com/kuenishi>`_ or `Bitbucket
<https://bitbucket.org/kuenishi>`_ account for all personal software.

- `Apache Ozone <https://ozone.apache.org>`_
- `cppetcd <https://github.com/kuenishi/cppetcd>`_ - a tiny `etcd
  <http://etcd.io>`_ v3 client in C++ (2018 -)
- `ChainerMN <https://github.com/chainer/chainermn>`_ along with Deep
  learning framework `Chainer <https://chainer.org>`_ (2017 -)
  Distributed Deep Learning Framework (in 2018 it was merged to Chainer v5)
- `Retz <https://github.com/retz/retz>`_ (2016 - 2018) Job scheduler as
  Apache Mesos framework
- `baccounts <https://github.com/kuenishi/baccounts>`_ (2016) - a tiny
  CUI password and account manager built with PGP encryption
- `A small piece of my work
  <https://github.com/erlang/otp/commit/966e9e7ed0951db306c3c5dc4b1fd4c6eac25cf9>`_
  is included in `Erlang/OTP 18.0
  <http://www.erlang.org/download/otp_src_18.0.readme>`_ !
- `meddatum <https://github.com/kuenishi/meddatum>`_ (2013-2015) : A
  tool to import/search/handle medical record formats with Riak
  Search 2.
- `fluent-logger-erlang <https://github.com/fluent/fluent-logger-erlang>`_
- `Riak <https://github.com/basho/riak>`_ , `Riak CS <https://github.com/basho/riak_cs>`_ (2012-2016)
- `fluent-plugin-riak <https://github.com/kuenishi/fluent-plugin-riak>`_
- `presto-riak <https://github.com/kuenishi/presto-riak>`_ : A `PrestoDB <https://prestodb.io>`_ connector of Riak.
- `Jubatus <http://jubat.us>`_ (2009-2012) is a distributed
  online machine learning framework and library. Jubatus is a joint
  work of `Preferreed Infrastructure <http://preferred.jp>`_ and `NTT
  Information Sharing Platform Laboratory
  <http://www2.pflab.ecl.ntt.co.jp/>`_. I designed the architecture
  the "mix" - softly synchronizing data for parallel machine learning
  and the server framework to make it applicable to various machine
  learning algorithms.

 - Modified Python generation of `msgpack-idl
   <http://hackage.haskell.org/package/msgpack-idl>`_ to use in
   Jubatus
 - Added Erlang generation of `msgpack-idl <http://hackage.haskell.org/package/msgpack-idl>`_
 - A small patch sent to `msgpack-rpc-python <http://pypi.python.org/pypi/msgpack-rpc-python/>`_ to use in Jubatus

- `MessagePack (Erlang) <http://msgpack.org>`_ (2010-)

 - MessagePack is a binary-based efficient object serialization
   library. It enables to exchange structured objects between many
   languages like JSON. But unlike JSON, it is very fast and
   small. Participating as a committer of Erlang-binding of both
   MessagePack and MessagePack-RPC.
 - In 2012, MessagePack-RPC/Erlang are updated to `ranch <https://github.com/extend/ranch>`_ -based system from a system with its own transport layer.

- Yatce: yet another TokyoCabinet-Erlang binding (2009)

 - Erlang's built-in key/value storage system (dets) is very slow and
   its performance is bad. While TokyoCabinet is a blazingly-fast
   key/value storage system written in state-of-art C, Yatce connects
   it with Erlang. It is built into some proprietary software and
   being sold (Yatce itself is dual-licensed as LGPL/MIT).

- Mercurial Message Translation (2009)

 - Mercurial is a Python-based distributed version control
   software. My contribution was next to project leader, flying-foozy
   (Mr. Fujiwara) - Almost 200 messages.

- Japanese translation of *CouchDB: the Definitive Guide* (2009-2011)

 - As the book's script is open by CC-3.0 license, I started
   translation project with same licence. Many people participated on
   translation and finally got `finished
   <http://couchdb-jp.github.com/couchdb-guide/editions/1/ja/index.html>`_
   (`the project page
   <https://github.com/couchdb-jp/couchdb-guide/>`_).
