How do I set a CSS url to an absolute location?

I'm working on an HTML5 mobile app and I initially have the background of a DIV item set through the CSS as follows: background-image: url('images/ClanSpider.png'); In my app, I have a method that changes the background DIV based on a selection made in a dropdown list from a previous method using jQuery: function ResetMyHonor() { ClanImage = 'images/Clan' + MyClanName + '.png'; $("#MyClanName").html(MyClanName); $("#MyHonorBox").css('backgroundImage', 'url(' + ClanImage + ')'); } All of this works fine when I'm on the root of my page. However, I have some links within the app using hash tags

Decltype of member functions

class A { int f(int x, int j) { return 2;} decltype(f)* p; }; Gives me the error: error: decltype cannot resolve address of overloaded function I can't understand why that error is even speaking of overloaded functions. Similarly I thought that maybe I needed to use the scope operator to access the function: class A { int f(int x, int j) { return 2;} decltype(A::f)* p; }; Which still gives me an error but a clearer description: error: invalid use of non-static member function 'int A::f(int, int)' Why is it that I'm not allowed to use decltype to find the type of a member function

Can we create custom Rust operators?

I know we can implement traits that override the standard arithmetic operators. Can we also create our own traits that overload custom operators? I have come to really enjoy Haskell's system for defining operators.

Cypress: type tab key

I want to test that my forms are accessible and that I can tab between my input elements. I found this github issue asking for the feature here: https://github.com/cypress-io/cypress/issues/299 Currently I try to do .type('{tab}') and I get the following error: CypressError: {tab} isn't a supported character sequence. You'll want to use the command cy.tab(), which is not ready yet, but when it is done that's what you'll use. Is there a current workaround for the lack of tab support?

Trying to Start MySQL Server and Getting "Could not start server: argument 2: <class 'TypeError'>: wrong type"

I just installed MySQL using the community installer in hopes of running a server and creating a database for use in my C++ program. I installed the Server, Workbench, Shell, Router, and Connector/C++ before running the Workbench. Everything appeared to be working properly. The server was running and I was able to connect to it in my C++ program, so I started to create my database, when the power suddenly went out before I could finish. Once the power came back on and my PC rebooted, I reopened the MySQL Workbench to find that I was unable to start the server. I clicked the 'Start Server'

Unique values on multiple columns

I need to get a list of unique values from few columns. The data looks like this: I tried using Unique but it only gives me copy of the list. These 4 lists are already unique values found in another sheet. If getting unique from 4 columns is impossible, how would I go around combining these 4 columns but instead merging data from a row to 1 cell I'd like to append that one column to have one city per row (so add more rows). Another idea I had - pulling data from multiple sheets into 1 row, but as it's an automated report, number of towns in each sheet changes every time, so can't use specific

ValueError: Units 'M' and 'Y' are no longer supported, as they do not represent unambiguous timedelta values durations

I recently upgraded my code from Python 3.3 to Python 3.7, and it's currently throwing an error which says: ValueError: Units 'M' and 'Y' are no longer supported, as they do not represent unambiguous timedelta values durations Which is puzzling, because the code was working fine before the upgrade. Here's the offending part of the code: df['date_modified'] = (df['date_variable']-pd.to_timedelta(df['years_variable'], unit = 'Y')).dt.date And here is the full code: import pandas as pd import numpy as np idx = [np.array(['Jan-18', 'Jan-18', 'Feb-18', 'Mar-18', 'Mar-18', 'Mar-18','Apr-18', 'Apr-18
