QUESTION
I have two large-ish data frames I am trying to append...
In df1, I have state codes, county codes, state names (Alabama, Alaska, etc.), county names, and years from 2010:2020.
In df2, I have county names, state abbreviations (AL, AK), and data for the year 2010 (which I am trying to merge into df1. The issue lies in that without specifying the state name and simply merging df1 and df2, some of the data which I am trying to get into df1 is duplicated due to there being some counties with the same name...hence, I am trying to also join by state to prevent this, but I have state abbreviations, and state names.
Is there any way in which I can make either the state names in df1 abbreviations, or the state names in df2 full names? Please let me know! Thank you for the help.
Edit: dput(df2)

QUESTION
The goal for my code is to make a rough roadmap using the latitude and longitude of the exits on the pennsylvania turnpike drawing a line between each exit.
I am using a for loop to plot a line on the map every time it loops. This works if i hard code the latitude and longitude but as soon as i plug in my variables nothing gets plotted. Since the coordinates are in order I am just increasing the index every time it loops to get the next coordinates. I have printed the variables inside the loop and verified they have the desired value. I have tried putting the values in ordered pairs but the plot function didn't like me using nparrays. I'm not sure if there is something simple i am missing, but I appreciate any input.
...ANSWER
Answered 2022-Apr-17 at 19:11Okay, based on the discussion above, see below for a solution.
Notes:
- Am using pandas DataFames to easily work with the
.csv
file. thenames
field is the column names. - Am not using orthographic projection at all.
- Am iterating through the list of highway exits one exit at a time; at each index, am extracting the current and next exits' data - am sure there's a more 'pythonic' way to do this, but this is readable at least.
- edit: the final index in the loop is length-1

I have:
...ANSWER
Answered 2022-Mar-31 at 09:50The easiest way to do that is adding a new attribute to the div
that you want to toggle.
I added new attribute which name is data-target
to your fl-module divs
. So, you can easily define your real target about that div
in the Javascript part.
The another problem in your code was self
. To define the element that has action, you need to use this
. I changed that part and also I made some improvements and simplifications in your Jquery code.

I am confused with this behavior, I have the following script:
backup.sh
ANSWER
Answered 2022-Feb-12 at 12:10It's not a bug, just a feature!
When you use the bash -c 'code …'
style, actually the first CLI argument is passed to the inline code as $0
, not $1
.
Furthermore, if the 'code …'
itself invokes an external script such as ./script.sh
, then you should not forget to pass the arguments using the "$@"
construct.
So you could just write (as pointed out in the comments):

I am trying to save Multiple Choice Fields in an array inside my database
I have no idea how to do this, I have a working solution by using the standard ChoiceField but it only saves one option at the moment
I want my values inside the database to show as for example "Beavers, Cubs" or "Scouts, Cubs"
How can I change my current code to do this?

QUESTION
I am trying to show only the first two rows of a CSS GRID.
The width of the container is unknown therefore it should be responsive.
Also the content of each box is unknown.
My current hacky solution is to define the following two rules:
- use an automatic height for the first two rows
- set the height of the next 277 rows to 0 height
grid-auto-rows: auto auto 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0;
I tried repeat() like this: grid-auto-rows: auto auto repeat(277, 0px)
but unfortunately it didn't set the height to 0.
Is there any clean way to repeat height 0?

Paragraph text is not 400 weight as expected, it renders at 600 weight the same as h1. If I switch my @font-face declarations then both the h1 and p render at 400 weight. So the last @font-face declaration is the only one that gets rendered.

QUESTION
I've been struggling with this for longer than I care to admit and would really appreciate some help.
I'm trying to do a project which involves building a linker and scheduler, and thought if I could use some of the functionality that's already been build into LLVM that would be great. I'm using LLVM 10. To get started I did some reading and tried to build this example. Because I plan on embedding LLVM into another project, used this as a reference for 'how to build' the example (see below). I figured the dependencies are just the components from the example CMakeLists.txt.
If I'm not mistaken, I'm getting a linker error and that the component list is the problem, but I'm struggling to resolve it. The way it seems LLVM does linking is by mapping a component name to an library file, but since I don't know which missing library might be causing it I'm stuck. Also, I don't know what llvm_libs is, but adding it to the component list seemed to resolve some of the linker errors I was getting originally. Also also, changing the order of the component list will give me different amounts of errors, which absolutely confounds me.
CMakeLists.txt
