Updating linux time
In this article we will look at some basic time-related commands, verify that timesyncd is active, and learn how to install an alternate network time service.
Before starting this tutorial, you will need an Ubuntu 16.04 server with a non-root, sudo-enabled user, as described in this Ubuntu 16.04 server setup tutorial.
Plus the terminal remains available for monitoring commands while plotting.
See or https://pypi.python.org/pypi/joystick (use pip install joystick to install) Just replace np.random.random() by your real data point read from the serial port in the code below: import joystick as jk import numpy as np import time class test(jk.
Click i DRAC Settings Update and Rollback in the left pane.
When the Firmware Update page opens, click Choose File Navigate to your update and select it.
Given that you say that your data arrival time is uncertain your best bet is probably just to do something like: import matplotlib.pyplot as plt import numpy hl, = plt.plot(, ) def update_line(hl, new_data): hl.set_xdata(numpy.append(hl.get_xdata(), new_data)) hl.set_ydata(numpy.append(hl.get_ydata(), new_data)) plt.draw() Since there is no call to show(), the plot never appears on the screen.
If I call show(), it blocks and doesn't perform the updates. gist.github.com/daviddoria/027b5c158b6f200527a4import matplotlib.pyplot as plt plt.ion() class Dynamic Update(): #Suppose we know the x range min_x = 0 max_x = 10 def on_launch(self): #Set up plot self.figure, = plt.subplots() self.lines, = plot(,, 'o') #Autoscale on unknown axis and known lims on the other set_autoscaley_on(True) set_xlim(self.min_x, self.max_x) #Other stuff grid() ...
Each method basically sets the property can simply be extended, so you can keep the previous points and just keep adding to your line (or image or whatever you are drawing).
The most basic command for finding out the time on your server is , the time at zero degrees longitude. 16 p - 64 0 0.000 0.000 0.000 -makaki.2.77 2 u 45 64 3 248.007 -0.489 1.137 -.7 220.127.116.11 3 u 43 64 3 90.551 4.316 0.550 static-ip-85-25 130.1 2 u 42 64 3 80.044 -2.829 0.900 gg 1.108 2 u 40 64 3 83.331 -0.385 0.391 flag asks for information about the NTP servers (or peers) ntpd has connected to.
