open swimming pool

Refer to https://www.youtube.com/watch?v=X22a7vASHsg&t=566s
0. Open earilier so it's cleaner
1. Remove the safety cover (may need pool cover popper)
screw down the anchors
2. Clean large debris
3. Remove plugs (should see bubbles)
4. Remove a gizmo in skimmer, a plug to the filter
5. Put skimmer bucket back
6. For the filter plug installation
Put the drain plug on the filter bottom
Put on the pressure gauage (if there's any)
Put on the sight gauage/glass
Drain plugs for the pump housing
Check the lid O-ring, no cracks, no brittle or dry (may need teflon based lubricant to seal)
Twist the lid
7. Filter operation
Turn the knob to Filter (first waste)
If your pressure gauge shows a sudden spike, shut off your pump immediately.
Turn it on


To clean the water:
1. Shock for the algae
one pound of shock for 10 thousand gallons of water, should be shocking at night
Put the shock into the bucket, stir nice and pour evenly into the pool

 

pywinauto note

1. start and lookup
backend="win32" is default backend, good for MFC, VB6, VCL, simple WinForms controls and most of the old legacy apps
from pywinauto.application import Application
app = Application(backend="uia").start('notepad.exe')
dlg_spec = app.window(title='无标题 - 记事本')
>>> dlg_spec
>>> dlg_spec.wrapper_object()                   
Actual window lookup is performed by wrapper_object(), it needs the window is on foreground
>>> dlg_spec.print_control_identifiers()

2. magic lookup
app.UntitledNotepad.menu_select("File->SaveAs")
app.SaveAs.ComboBox5.select("UTF-8")
At the 2nd line the SaveAs dialog might not be open by the time this line is executed. So what happens is that we wait until we have a
control to resolve before resolving the dialog. At that point if we can’t find a SaveAs dialog with a ComboBox5 control then we wait a
very short period of time and try again, this is repeated up to a maximum time (currently 5 seconds!)
This is to avoid having to use time.sleep or a “wait” function explicitly.
In some cases, you might prefer disable the magic lookup system, so that Pywinauto immediately raises if you access an attribute
which exists neither on the WindowSpecification object, nor on the underlying element-wrapper object.
In this case, turn off the allow_magic_lookup argument of your Desktop or Application instance:
app = Application(allow_magic_lookup=False)

3. sample notepad in Chinese
from pywinauto import application
app = application.Application()
app.start("Notepad.exe")
app['无标题 - 记事本'].draw_outline()
app['无标题 - 记事本'].menu_select("编辑 -> 替换(&R)...")
app['替换'].print_control_identifiers()
app['替换'].取消.click()
app['无标题 - 记事本'].Edit.type_keys("Hi from Python interactive prompt %s" % str(dir()), with_spaces = True)
app['无标题 - 记事本'].menu_select("文件 -> 退出")
app['记事本'].不保存.click()

4. Huatai
import time
from pywinauto import application

app = application.Application()
app.start("c:/htwt/xiadan.exe")
#app['用户登录'].print_control_identifiers()
app['用户登录'].主站测速.click()

time.sleep(1)
app['<华泰证券>委托连接测试'].开始测速.click()
while True:
try:
app['<华泰证券>委托连接测试'].开始测速.wait("enabled")
break
except RuntimeError:
pass

print(app['<华泰证券>委托连接测试'].开始测速.is_enabled())
app['<华泰证券>委托连接测试'].确定.click()

app['用户登录'].Edit1.set_focus()
app['用户登录'].Edit1.type_keys('******')

5.
dlg = app.window(title_re="Page Setup", class_name="#32770")
app['dlg']['control']
app[u'your dlg title'][u'your ctrl title']

6.
# call ensure_text_changed(ctrl) every 2 sec until it's passed or timeout (4 sec) is expired
@always_wait_until_passes(4, 2)
def ensure_text_changed(ctrl):
    if previous_text == ctrl.window_text():
        raise ValueError('The ctrl text remains the same while change is expected')

7.
from timings import Timings

Timings.defaults()
Timings.slow() # double all timings (~2x slower script execution)
Timings.fast() # divide all timings by two (~2x faster)

8.
DELAYED RESOLUTION FOR SUCCESS Taking the example
app.dlg.control.action()

Python Flask

Python Flask restful web service

1. Install Python3 and flask (my python is 3.8.0)
2. Make a hello.py accordign to the flask quick start
https://flask.palletsprojects.com/en/1.1.x/quickstart/#quickstart

from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello, World!'

3.On windows, from command line, run "FLASK_APP=hello.py"

 and flask run --host=0.0.0.0 --port=80

4. Other computer on the same LAN now is able to access the service (virtualbox needs to be 

bridge adapter)

股票软件比较

股票软件比较：
1. 网季风
   下载网季风行情接收器和飞狐交易师，可以全推接收行情，盘后可用免费账号连入。
   问题：自己制作的DLL不能使用
2. 飞狐交易师V5.1版
   百度搜索 “飞狐交易师V5.1版”并下载
   http://www.pc6.com/softview/SoftView_135985.html
   安装后点“免费登录”即可连接行情使用（不用额外下载任何行情接收器）
   问题：定制的DLL可以使用，但行情接收速度不稳定
3. 大交易师
   基于飞狐交易师的现代化图形界面，速度快，对定制DLL和股票公式的支持好
   缺点：不能批量导出数据（可用定制DLL一个个导出）
4. 金魔方
   和大交易师几乎完全相同，除了速度更慢之外，也不能批量导出数据

总结：
需要一个网季风（虚拟机）和一个大交易师（主机）

Remove a file within the dependency jar from moven ear

https://stackoverflow.com/questions/2830837/remove-file-from-dependency-jar-using-maven

Parent pom has multiple children and all children refers to a scheduler task except 1. Child 1 is deployed to VM1 JBoss, child 2 is deployed to VM2 JBoss ..
For JBoss configuration, it contains the item for scheduler tasks (like cron information) which is not needed on child 3. In this case, needs exclude the spring-tasks.xml from the core*.jar.
