$ sudo pip install cythonAfter cython installed, then install PyJNIus through php or easy install. In this case I use pip
$ sudo pip install PyJniusAfter PyJnius installed then try import jnius from python, and let learn little thing about calling java from python.
Python 3.4.3 (default, Mar 10 2015, 14:53:35)But on OSX we sometime meet this error when import jnius

a start job is running for create volatile files and directoriesI search internet but I got nothing to solve my problems, then I try to view my manjaro setting then I take look on kernel section, I know that my kernel is need to be upgrade. Manjaro system will notif recommended kernel version for installed system if newer kernel exist.
.steam or ~/.local/share/steam directories, or invoked Steam’s Bash script with the —reset option enabled.UPDATE: Valve gave us the following statement: "So far we have had a handful of users report this issue, after they manually moved their Steam install. We have not been able to reproduce the reported issue, but we are adding some additional checks to ensure this is not possible while we continue to investigate. If anyone else has experienced this or has more information, they should email linux@valvesoftware.com."
rm -rf “$STEAMROOT/“*. That command is a basic Bash instruction that tells the computer to remove the STEAMROOT directory and all its sub-directories (folders).rm -rf “/“*, as first reported by Bit-Tech.
If you’re not familiar with Bash, that command tells the system to
delete everything on your hard drive starting from the root directory.# Scary!.2to3, which takes your actual Python 2 source code as input and auto-converts as much as it can to Python 3. Case study: porting chardet to Python 3 describes how to run the 2to3 script, then shows some things it can’t fix automatically. This appendix documents what it can fix automatically. print was a statement. Whatever you wanted to print simply followed the print keyword. In Python 3, print() is a function. Whatever you want to print, pass it to print() like any other function.

print() without any arguments.
print() with one argument.
print() with two arguments.
print statement with a comma, it would print the values separated by spaces, then print a trailing space, then stop without printing a carriage return. (Technically, it’s a little more complicated than that. The print statement in Python 2 used a now-deprecated attribute called softspace. Instead of printing a space, Python 2 would set sys.stdout.softspace to 1. The space character wasn’t really printed until something else got printed on the same line. If the next print statement printed a carriage return, sys.stdout.softspace would be set to 0 and the space would never be printed. You probably never noticed the difference unless your application was sensitive to the presence or absence of trailing whitespace in print-generated output.) In Python 3, the way to do this is to pass end=' ' as a keyword argument to the print() function. The end argument defaults to '\n' (a carriage return), so overriding it will suppress the carriage return after printing the other arguments.
sys.stderr — by using the >>pipe_name syntax. In Python 3, the way to do this is to pass the pipe in the file keyword argument. The file argument defaults to sys.stdout (standard out), so overriding it will output to a different pipe instead.
os.path.walk method can be awkward to use, so from now on we'll stick to the os.walk method, this way the script will be simpler and compatible with both branches.topdir
variable, but only found files of one extension. Let's now expand that
to find files of multiple extensions in select folders under the topdir path. We'll first search for files of three different file extensions: .txt, .pdf, and .doc. Our extens variable will be a list of strings instead of one:walk function in the os.path module or the walk function in the os module (using Python version 2.x or Python 3.x, respectively).>>> a, b, c = 1, 2, 3 >>> a, b, c (1, 2, 3) >>> a, b, c = [1, 2, 3] >>> a, b, c (1, 2, 3) >>> a, b, c = (2 * i + 1 for i in range(3)) >>> a, b, c (1, 3, 5) >>> a, (b, c), d = [1, (2, 3), 4] >>> a 1 >>> b 2 >>> c 3 >>> d 4
