latr | A scala macro for reasonable lazy semantics | Functional Programming library

I did something to mess up my DNS on my virtual ubuntu 16.04 box. Can you help me diagnose what the problem is and get DNS working again. I am able to connect to servers using an ip address. However, when I use hostnames, my box can't resolve them. This used to work - I did something to mess it up, but don't remember what file I edited.

I am making a page with responsive layout. I can not manage to put 2 DIVs under one DIV element. I tried Flexbox, Float and other solutions from here.

col-1,col-2 and col-3 are all inside .three-col div

Here is the CSS:

I am trying to setup my project to deploy a go applicaiton. When I try to use sed with a parameter that is passed in from the job - it works fine When I try to use sed with a paramater that is passed in from the job which is referenced as a context variable it is not working. See this example

I've filtered all the messages I want to request into a label in Gmail and I'm successfully getting mail back by using this bit of code in their quickstart.py script:

I have written a MS Access VBA function to calculate new latitude/longitude co-ordinates from a bearing and distance. However it is returning the wrong results and I can't see why. I used the formulae on https://www.movable-type.co.uk/scripts/latlong.html However when I test it against the calculator on that page, it gives the wrong results. For example NewLatLong(0, 0, 500, "K", 45) gives a latitude of 5.54656612024095E-02 and a longitude of 0. The latitude is correct after converting to degrees to compare with the calculator on the page, but why does the longitude come back as zero? The parameters for NewLatLong are original latitude and longitude in degrees, distance, distance unit (K = kilometers) and bearing clockwise from north in degrees.

MS Access does not have all the trigonometric fuctions required. I have provided new ones. These have been separately tested and appear to function correct.

I can't see what is wrong with my code. Can anyone help.

I was performing some experiments in Docker and found a strange behaviour.

I was able to override the ownership of a file created with the root user inside the Docker with another user without root permissions.

Below are the steps to reproduce it:

I'm interested in retrieving latitude and longitude data corresponding to the points listed both on the map and within the downloadable files on the links I've listed. I'm looking for this data so that I can find co-located EPA sites.

Currently, there is no latitude and longitude data openly available on the website, but when you download the files their titles end up being like the following example:

This is my first question here, so point me out if I do something wrong.

I was implementing the equation to calculate an spherical angle (https://en.wikipedia.org/wiki/Solution_of_triangles#Solving_spherical_triangles). As math.acos and np.arccos are only defined for [-1,1] I hat to code a try/except statement. It worked well with math.acos, but I keep getting

RuntimeWarning: invalid value encountered in arccos

when I use np.arccos. As I want to do calculate the spherical angle for a very long file, I need np.arccos so I can get the benefits of vectorizarion. Any ideas on why this is happening or how I can imprrove the code?

Here is my attempt:

I have different data which were created at different date and time shown below.
