Generate keys:

KeyPairGenerator kpg = KeyPairGenerator.getInstance("EC");
kpg.initialize(new ECGenParameterSpec("secp521r1"), new SecureRandom());
KeyPair keyPair = kpg.generateKeyPair();
ECPrivateKey privateKey = (ECPrivateKey) keyPair.getPrivate();
ECPublicKey publicKey = (ECPublicKey) keyPair.getPublic();
byte[] privateKeyS = privateKey.getS().toByteArray();
byte[] publicKeyX = publicKey.getW().getAffineX().toByteArray();

byte[] publicKeyY = publicKey.getW().getAffineY().toByteArray();

How to Set up an Ethereum Dev Environment

So you want to be an Ethereum developer! Congrats, much treasure awaits you. Developing Ethereum dapps benefits from having a well-crafted development environment. This can often be daunting to beginners, so I'm giving you my favorite dev environment to help get you started.

Once your code fortress is constructed, you'll be able to

程序行为：
这一小时里，gc线程的cpu都是100%，占用系统大量CPU，不停的进行full gc，但是进程没有oom error退出。大概一小时左右会oom error退出。

程序在干什么：
Hive客户端程序，有一些SQL需要上亿的文件，所以这个程序需要启动，去遍历所有文件，并且缓存到内存，产生SQL job所需要的计算，
因而文件数太多会导致堆内存不足。希望这种情况下直接报oom退出即可。

jdk：
jdk是1.7.0_55，不过换到jdk1.8.0_91，症状类似，都是1小时才报错oom。

Step 1 - Make a Discord Webhook

1. Find the Discord channel in which you would like to send commits and other updates

2. In the settings for that channel, find the Webhooks option and create a new webhook. Note: Do NOT give this URL out to the public. Anyone or service can post messages to this channel, without even needing to be in the server. Keep it safe!

Step 2 - Set up the webhook on Github

1. Navigate to your repository on Github, and open the Settings
