Slow and steady
Ethereum only processes 10 to 15 transactions per second, in large part because all nodes are required to help process all transactions made through the database. By comparison, a credit card company like Visa can process around 45,000 transactions per second.
2、拿財團來當例子… 上面說政府要退出媒體，這裡討論財團買媒體，假設財團不買媒體，媒體怎麼生存，誰要買？嗯，有人提到那就定下法律媒體必OOXX來保障，這有腦嗎？多想想這件事，就會發現這又是一個很可笑的答案
a. TVBS炒HTC
b. 三立炒牧場
請問別家媒體會跟TVBS、三立一起炒嗎？這又扯到另一個買報導問題
一個獨立思考，有公正能力判斷的人，看媒體只看一家，一直看一家報導？？！！只看自己喜歡看的？那他怎麼會認為自己是有公正能力判斷的人？假如他看了多家媒體，自然怎麼會被洗腦？？！！是自己願意被洗還是怪別人來洗？
這些非常簡單，思考一下，就能得到論述及答案，這支影片怎麼都沒提到，看到這裡，這支影片和它的標題已經漸行漸遠了
If you npm install a Cordova/Capacitor plugin after npx cap add android then make sure you run npx cap update before running from Android Studio again.
If you make html, js, ts, css changes, run ionic build again and also run npx cap copy.
Or when in doubt, run npx cap sync as it does update+copy.
SIEGE 3.0.6
Usage: siege [options]
siege [options] URL
siege -g URL
Options:
-V, --version VERSION, prints the version number.
-h, --help HELP, prints this section.
-C, --config CONFIGURATION, show the current config.
#在屏幕上打印显示出当前的配置,配置是包括在他的配置文件$HOME/.siegerc中,
#可以编辑里面的参数,这样每次siege 都会按照它运行.
-v, --verbose VERBOSE, prints notification to screen.
#运行时能看到详细的运行信息
-q, --quiet QUIET turns verbose off and suppresses output.
-g, --get GET, pull down HTTP headers and display the
transaction. Great for application debugging.
-c, --concurrent=NUM CONCURRENT users, default is 10
#模拟有n个用户在同时访问,n不要设得太大,因为越大,siege 消耗本地机器的资源越多
-i, --internet INTERNET user simulation, hits URLs randomly.
#随机访问urls.txt中的url列表项,以此模拟真实的访问情况(随机性)
-b, --benchmark BENCHMARK: no delays between requests.
-t, --time=NUMm TIMED testing where "m" is modifier S, M, or H
ex: --time=1H, one hour test.
#持续运行siege ‘n’秒(如10S),分钟(10M),小时(10H)
-r, --reps=NUM REPS, number of times to run the test.
#重复运行测试n次,不能与 -t同时存在
-f, --file=FILE FILE, select a specific URLS FILE.
#指定用urls文件,默认为siege安装目录下的etc/urls.txt
#urls.txt文件：是很多行待测试URL的列表以换行符断开,格式为:
#[protocol://]host.domain.com[:port][path/to/file]
-R, --rc=FILE RC, specify an siegerc file
#指定用特定的siege配置文件来运行,默认的为$HOME/.siegerc
-l, --log[=FILE] LOG to FILE. If FILE is not specified, the
default is used: PREFIX/var/siege.log
#运行结束,将统计数据保存到日志文件siege.log中,可在.siegerc中自定义日志文件
-m, --mark="text" MARK, mark the log file with a string.
-d, --delay=NUM Time DELAY, random delay before each requst
between 1 and NUM. (NOT COUNTED IN STATS)
#hit每个url之间的延迟,在0-n之间
-H, --header="text" Add a header to request (can be many)
-A, --user-agent="text" Sets User-Agent in request
-T, --content-type="text" Sets Content-Type in request
** SIEGE 2.72
** Preparing 300 concurrent users for battle.
The server is now under siege.. done.
A permission allows an actor to perform a certain action in a system: Bob is allowed to delete his own photos.
OAuth 2.0 Scope implies that an end-user granted certain privileges to a client: Bob allowed the OAuth 2.0 Client to delete all users.
The OAuth 2.0 Scope can be granted without the end-user actually having the right permissions. In the examples above, Bob granted an OAuth 2.0 Client the permission ("scope") to delete all users in his name. However, since Bob is not an administrator, that permission ("access control") is not actually granted to Bob. Therefore any request by the OAuth 2.0 Client that tries to delete users on behalf of Bob should fail.
When login success, context data be saved .
Can use
GET https://openid.hydra:9002/oauth2/auth/sessions/consent?subject=foo@bar.com HTTP/1.1
check by subject.
This step is different quickstart.yml. Use https and t.tt domain. quickstart.yml start serve --dangerous-force-http
All become http. So last step can callback use http. This production way only use https. And token user only http. So use self OpenID client.
PS：
Here REST Client still return login page. go main server error log:
Post https://openid.hydra:9001/oauth2/token: x509: certificate signed by unknown authority
This is Go Server problem. See main.go Line：55-61 82-94 Fix this problem.
========== old ==========
3、Now have problem is token user. When you run *A, try to open web broswer. http://192.168.99.100:9010 then click "Authorize application" get error.
Because "Authorize application" still is 127.0.0.1. No way to change. So copy Link change it.
F... Now follow step run, Get level=error msg="An error occurred" debug="No CSRF value available in the session cookie" description="The request is not allowed" error=request_forbidden hint="You are not allowed to perform this action."
If you run same broswer and restart docker or clear cookie, do many way. Just try broswer private mode.
Try dex docker or binary failed, it's be pass.

在Ubuntu Server 18.04 LTS下遇到了sudo速度非常慢的问题，具体表现是在提交命令之后大概需要10秒左右才有输入sudo密码或者开始运行，su命令同样也非常慢。这在升级前使用Ubuntu Server 16.04 LTS并没有，显然可能是Ubuntu Server 18.04 LTS版本的问题。
transaction A get nonce 1
transaction B get nonce 2
transaction C get nonce 3
But blockchain package B、C first, then package A. If happen this step, get error.
With truffle？
Because
Normal
const wallet = new HDWalletProvider(mnemonic, url, id);
const AContract = new TruffleContract(Json_contract);
AContract.setProvider(wallet);
wallet.addresses[]
AContract. use contract api
Sometime you call contract "set/write" api two times.
Example：
Create contract first. Write data into contract second. This two step are in one function. This mean is you call two time "new HDWalletProvide". Usually you think “New“ two time is ok, get "new" instance. But
