What does the method getProperty () & # 39; of the class "System"?

String lineSepString = System.getProperty ("line.separator");
char lineSep = lineSepString.charAt (lineSepString.length () - 1);

Can any one tell me what this code does?

In Slack, we start a quoted paragraph with >>>.

Is there a way to finish the quoted paragraph and continue to write more not cited text in the even message?

No sound from the speakers, audio output & # 39; speaker & # 39; Not available

I am under Ubuntu 18.04,
I've had a problem with my sound for a while now. The sound is automatically replaced by the headphones, but the speakers are not displayed as audio output.

But, after restarting the desktop, the audio output is automatically set as "speaker". The speaker works normally.

semantics – Validation Tribulation – Multiple simultaneous meanings for the word & # 39; Cancel & # 39;

I got mixed up with a lot of different Cancel buttons.

In this scenario, the user launches the "Document Packer" and begins adding items to his new pack. Before saving their new pack, they can change their mind and get rid of their current work by clicking the "Cancel" button. [Step 1 in the diagram below]. The validation seems to confirm their premature exit.

However, what words should I use to cancel / confirm this validation? [Step 2 in the diagram below]

I now have two opposite meanings for the word "cancel".

Rather than "cancel", I reformulated the validation confirmation at "Exit Now", but even that sounds a little complicated.

Help me!

unit – error CS1069: the type name & # 39; ZipArchive & # 39; could not be found in the namespace 'System.IO.Compression & # 39;

When I build my project, which references the Compression System.IO. namespace, the build succeeds without problems in Visual Studio.

However, in the Unity editor, the following error appears:

error CS1069: The type name & # 39; ZipArchive & # 39; could not be found in the namespace "System.IO.Compression". This type was passed to the assembly 'System.IO.Compression, version = 4.0.0.0, Culture = neutral, PublicKeyToken = b77a5c561934e089'. Consider adding a reference to this assembly.

I added a csc.rsp file in my Assets folder, with the following line:

-r: System.IO.Compression.FileSystem.dll

Unfortunately, this did not solve the problem.

Here are the properties of the Compression System.IO. DLL I refer in Visual Studio:

How can I fix this error?

r – The call of the Fortran subroutine in Python returns' NoneType & # 39;

I want to write a Python package containing the essential features of the KernSmooth R package managed by Brian Ripley. Most of the code for KernSmooth of R is written in Fortran77 syntax. So, basically, imitating what Brian Ripley did in R, my plan is to import the Fortran subroutines into Python and write the corresponding user interface. For starters, I'd like to put the Fortran77 subroutine rlbin.f (code below) in a Python function.

c Part of the KernSmooth R package

ccccccccccc subroutine FORTRAN rlbin.f cccccccccc

c Get the number of bins for univariate regression data
c via the linear binning strategy. If "trun = 0" then
c the weight of the concluding observations is attributed to
c end of the grid points. If "trun = 1" then end of observations
c are truncated.

c Initialize grid counts to zero

xcnts (i) = dble (0)
ycnts (i) = dble (0)

delta = (b-a) / (M-1)

lxi = ((X (i) -a) / delta) + 1

c Find an entire part of "lxi"

li = int (lxi)
rem = lxi - li
if (li.ge.1.and.li.lt.M) then
xcnts (li) = xcnts (li) + (1-rem)
xcnts (li + 1) = xcnts (li + 1) + rem
ycnts (li) = ycnts (li) + (1-rem) * y (i)
ycnts (li + 1) = ycnts (li + 1) + rem * y (i)
end if

if (li.lt.1.and.trun.eq.0) then
xcnts (1) = xcnts (1) + 1
ycnts (1) = ycnts (1) + y (i)
end if

if (li.ge.M.and.trun.eq.0) then
xcnts (M) = xcnts (M) + 1
ycnts (M) = ycnts (M) + y (i)

I've already successfully compiled FORTRAN code and I've imported it into Python.

I terminal I typed

f2py -c -m rlbin rlbin.f

create a shared library rlbin.so that I imported into Python:

import rlbin
print (rlbin .__ doc__)

Exit:

This module & # 39; rlbin & # 39; is automatically generated with f2py (version: 2).
The functions:
rlbin (x, y, n, a, b, m, trun, xcnts, ycnts)
.
print (rlbin.rlbin .__ doc__)

Exit:

rlbin (x, y, n, a, b, m, trun, xcnts, ycnts)

Wrapper for `` rlbin``.

Settings
----------
x: rank 1 (& # 39;) array with bounds (*)
y: rank 1 (& # 39;) chart with bounds (*)
n: int entry
a: float of entry
b: float of entry
m: int entry
trun: int entry
xcnts: array of entry of rank 1 (& # 39; d & # 39;) with terminals (*)
ycnts: array of entry of rank 1 (& # 39;) with terminals (*)

I have specified the input parameters as follows:

import numpy as np

# create random x and y arrays
x = np.ndarray (shape = (2000,), dtype = float, order = F)
y = np.ndarray (shape = (2000,), dtype = float, order = F)

n = len (x)
a = 0.05
b = 0.995
M = 500
trun = 1

xcents = np.zeros (M)
ycnts = np.zeros (M)

I've checked the data types: a and b are actually floats; not, M, and trun are integers; X, there, xcnst and Ycnts are numpy arrays.

And called the Fortran subroutine

out = rlbin.rlbin (x, y, n, a, b, m, trun, xcnts, ycnts)

which runs without error. Similarly, by calling outside do not throw any errors but do not return anything either.

type (out)returns however No Type and
to print) results No.

I tried the same procedure (compile, import, call) in R and it worked without any problem.

For those interested, the corresponding R call would be (from the ALL.R script, lines 713 through 724):

out <- .Fortran ("rlbin", as.double (x), as.double (y), as.integer (n),
as.double (a), double (b), as.intger (M), as.intger (trun), double (M), double (M))

I've already followed a few tutorials to check if my f2py environment is properly configured and, yes, I have no problem calling other Fortran subroutines in Python:

What irritates me, therefore, is that the call of the same Fortran subroutine in R using exactly the same input parameters works perfectly. Maybe Python handles the input settings differently from R, but I do not see how at this point.

I appreciate any help!

Why do not I download the pdf form when I put this code back $ pdf-> download (& # 39; invoice)

I have searched several places and here is the answer to download an HTML form in PDF format, but when I place it, I display it on the screen and I do not download it, what can I do?

Do you want to control your username for an administrator and an error if you want, go back to the previous list or the tutorial you want, but you should not go wrong.
