bitcoind立ち上げ方

Bitcoind側の立ち上げ方

Bitcoindを入れたファイルにある、srcというファイルに入ってから、

cd $HOME/bc2/bc2/src

ターミナルで以下。
./bitcoind -printtoconsole

 

立ち上がったら、ターミナルで(他のタブで)

./bitcoin-cli getnewaddress などのコマンドを打つ

GethとMeteorのセットアップメモ

 

gethのセットアップ

1:Ethereum(geth)でプライベート・ネットワークを作る手順 - Qiita

2:

Creating a Private Chain/Testnet | Ethereum Tutorials and Tips by Hudson

3: 

Private network · ethereum/go-ethereum Wiki · GitHub

 

エラー:

flag provided but not defined: -genesis

解決:

geth --fast -natspec -networkid="2" -nat "none" --nodiscover -port 0 console

エラー:

Fatal: Error starting protocol stack: chain db corrupted. Could not find block 0.

Genesis blockが見つからないという問題

解決:

1: $ geth --dev --datadir ./data init genesis.json
2: $ geth --datadir /Users/HOkaniwa/blockchain_projects/geth_test --fast -natspec -networkid="2" -nat "none" --nodiscover -port 0 console

 

Meteorセットアップ

 

Meteorのインストール (参照: Meteor)

$ curl https://install.meteor.com/ | sh

Downloading Meteor distribution
######################################################################## 100.0%

Meteor 1.5.1 has been installed in your home directory (~/.meteor).
Writing a launcher script to /usr/local/bin/meteor for your convenience.

To get started fast:

$ meteor create ~/my_cool_app
$ cd ~/my_cool_app
$ meteor

Or see the docs at:

docs.meteor.com

 

例えばtest_projectという名前のサンプルプロジェクトを作るコマンド:

$ meteor create test_project

または

$ meteor create ~/test_project

作成されたフォルダに行き、meteorと打つとサーバーが立てられて、ウェブブラウザでみることができる。

If you notice problems related to these missing modules, consider running:

meteor npm install --save babel-runtime

=> Your application is crashing. Waiting for file change.

1: flac ファイルをダウンロード

Speech to Text | Getting started | IBM Watson Developer Cloud より、以下でデモデータとして扱うファイルをダウンロードする。

 

2: BluemixのCatalogから、使いたいSpeech to Text機能を検索して選択

Speech to Textの検索画面

If you find the same file in another location then symlink it:

For ex: I have it in /data/mysql_datadir/mysql.sock

Switch user to mysql and execute as mentioned below:

su mysql

ln -s /data/mysql_datadir/mysql.sock /var/lib/mysql/mysql.sock
