kandi X-RAY | Nyx Summary
Nyx code solves equations of compressible hydrodynamics on an adaptive grid hierarchy coupled with an N-body treatment of dark matter. The gas dynamics in Nyx uses a finite volume methodology on a set of 3-D Eulerian grids; dark matter is represented as discrete particles moving under the influence of gravity. Particles are evolved via a particle-mesh method, using Cloud-in-Cell deposition/interpolation scheme. Both baryonic and dark matter contribute to the gravitational field. In addition, Nyx includes physics needed to accurately model the intergalactic medium: in optically thin limit and assuming ionization equilibrium, the code calculates heating and cooling processes of the primordial-composition gas in an ionizing ultraviolet background radiation field. Additional physics capabilities are under development. While Nyx can run on any Linux system in general, we particularly focus on supercomputer systems. Nyx is parallelized with MPI + X, where X can be OpenMP on multicore architectures and CUDA/HIP/DPC++ on hybrid CPU/GPU architectures. In the OpenMP regime, Nyx has been successfully run at parallel concurrency of up to 2,097,152 on NERSC's Cori-KNL. With Cuda implementation, it was run on up to 13,824 GPUs on OLCF's Summit. More information on Nyx can be found at the main web page and the online documentation.

I'm trying to get my api to display the data but it keeps returning the error books.map is not a function. I'm aware my array is empty when the page loads but and it may need a (books || []) but that didn't work either.. any ideas?
I just want to be able to map the data into the table and then manipulate it. When I console.log(books) I get the data I want but the map doesn't work.
My code:

Answered 2019-Jun-18 at 18:28First of all, make sure the div you're trying to make scrollable is wide enough for you to be able to scroll.
Then, you can use a lib like MouseWheel to detect scroll events and return the delta values you're going to use with scrollLeft.
The mousewheel lib: https://github.com/jquery/jquery-mousewheel
The code for that would be something like this:

QUESTION
My aim is to download stock prices using the quantmod library for a large number of ticker symbols (~700) and merge the results in a single dataframe which I will save as a csv file. I have a list of ticker symbols but not all of them are downloadable by quantmod.
So when I pass the list with the ticker symbols to the getSymbols() method, once it encounters a problem with a particular ticker symbol it stops and returns an exception. I am trying to circumvent this behavior with a for loop and the try method, but I fail.
Let's look at some code:
When I try to download two ticker symbols that are downloadable and then merge them into one xts object I succeed:

""" is so the concatenation of empty string "" with unfinished string.
To avoid this error/warning, you might use a variant: """ " and " """.
So you have concatenation of empty string with string with space in C++ and for python, you just have extra quote in your string.
Finally you have:

Answered 2017-Sep-16 at 10:03It turned out that the OWASP method whitelist valve was configured on Tomcat (Catalina) level to only allow GET and POST; this is a webapp that held only SOAP services until now. You do not see this in either web.xml's or server.xml, but it's in Catalina/localhost/webappname.xml.
