I am testing python code performance with uvloop. I am getting 'uvloop' has no attribute 'EventLoopPolicy' error.
I am using python 3.7 and
uvloop 0.13.0
pycharm
I tried changing interpreter reinstalling uvloop but none of them did not work.
Can anyone suggest what is the problem?
Rename your own file to something else than uvloop.py, such as test_uvloop.py.
You're confusing Python's import machinery by having your own file the same name as the library you're trying to use.
I see that you're on a Mac, but I just fixed this problem on my CentOS7.x server by properly setting permissions to the uvloop Python package. It's pesky because (at least on CentOS) some pip-installed Python packages go in /usr/local/lib/python3.7/site-packages and some go in /usr/local/lib64/python3.7/site-packages.
Check out what the files in my lib64 directory looked like before I fixed it:
me#myserver /usr/local/lib64/python3.7/site-packages

Unless I was running as a root user the uvloop files are untouchable and that's what caused the error. On your Mac, try to find where your uvloop package is installed and make sure your script can access it.

I want to connect a PostgreSQL database with a MongoDB by using Mongo_fdw. After following this instruction to install mongo_fdw with the autogen.sh script on Ubuntu 22.04 LTS, I wanted to check the connection and ran CREATE EXTENSION mongo_fdw; in my database, but the following error occured:
ERROR: could not access file "$libdir/mongo_fdw": No such file or directory
Searchig for a solution I found this page on GitHub, where the same error is discussed. Following the recommendations there, I checked pg_config --version, pg_config --libdir and pg_config --sharedir with the following results:
$ pg_config --version
PostgreSQL 12.9
$ pg_config --libdir
/home/qgis/anaconda3/lib
$ pg_config --sharedir
/home/qgis/anaconda3/share
When I check /home/qgis/anaconda3/share/extension I get the following files:
drwxrwxr-x 2 qgis qgis 4096 Feb 1 10:58 ./

I also ran ldconfig as it is recommended on the GitHub page but with no results.
Does someone has an idea how to solve this error?
Thanks in advance!
You have to specify the correct pg_config when building the software, probably
make PG_CONFIG=/usr/lib/postgresql/14/bin/pg_config
That file should exist if you installed the package with the C headers, which is typically called "devel" or "dev" or similar.
I attempted to install node.js/npm onto a macbook running Mojave 10.14.5 so that I can do local development of a web app. From internet research my understanding is the first step is updating homebrew in preparation for installation but I got the error "Error: /usr/local must be writable!" when I ran:
brew update
I searched the internet and other people appeared to have the command below fix the problem, but for me that didn't work and I still got the error.
sudo chown -R $(whoami) $(brew --prefix)/*
Can anyone offer any advice as to what I can do so that I can update brew and install node.js/npm? Is the brew update required or should I just skip that step?
Below is the output from brew --prefix that may help...

I have a website that was set up to use https using a certificate from Let's Encrypt. I am trying to add that certificate to a keystore to use https with a dropwizzard API. The problem I am having is that there are multiple certificates.
My question is how can I figure out which of the certificates my website uses so that I could use that for the API as well?
In /etc/ssl/certs this is what shows up:
lrwxrwxrwx 1 root root 49 Nov 20 2017 ca-bundle.crt -> /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
-rw-r--r-- 1 root root 885625 Apr 12 00:27 ca-bundle.crt.rpmnew
lrwxrwxrwx 1 root root 55 Nov 20 2017 ca-bundle.trust.crt -> /etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt
-rw-r--r-- 1 root root 1059673 Apr 12 00:27 ca-bundle.trust.crt.rpmnew
-rw------- 1 root root 1586 Dec 15 2017 localhost.crt
-rwxr-xr-x 1 root root 610 Aug 17 17:16 make-dummy-cert
-rw-r--r-- 1 root root 2516 Aug 17 17:16 Makefile
-rwxr-xr-x 1 root root 829 Aug 17 17:16 renew-dummy-cert
After looking more closely at the config files like Patrick had suggested I found the config file in /etc/httpd/conf.d/ssl.conf that had the path to where the certificate and private key were.
You can have a look at your vhost file to see the path to the physical ssl cert files being used by the website. The vhost is likely going to be at /etc/apache2/sites-available/ .

My question is what went wrong? To install java-9 i used:
sudo apt install openjdk-9-jre openjdk-9-jdk
I found an issue on idea tracker
https://youtrack.jetbrains.com/issue/IDEA-178743
It's fixed. Also users suggested x86_64- version. Try with it.(source)
Server: SLES v11 sp3
Kernel: 3.0.101-0.47.71-default
Arch: x86_64
So I am trying to build a src package and when I run the "./configure" script it's throwing some errors that required packages are missing. Since it's x86_64 I thought adding "--libdir=/usr/lib64" or "--libdir=/lib64" would help it find the packages it's looking for but I get the same error either way.
The configure Script is failing with this error:
..........
...SNIP...
..........
checking for xgettext... (cached) /usr/bin/xgettext
checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables GEDIT_CFLAGS
and GEDIT_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
I checked to make sure I actually have these packages and it seems as though I do. So I'm not sure if it's just not finding them or what... And it also seems as though I have versions of those packages >= what they are asking for, so I'm kinda stumped...
My Installed packages are:
# rpm -qa | grep -i glib-2

# rpm -qa | grep -i 'gtk2'

# rpm -qa | grep -i 'gedit'
gedit-2.28.3-0.8.1
gedit-lang-2.28.3-0.8.1
Anyone have any ideas what the issue could be here? I'm not sure what else to try..?
I had also tried installing the RPM based package but get similar errors for missing packages. See RPM Installation error below...
warning: gedit-plugins-2.28.0-2.el6.x86_64.rpm: Header V3 RSA/SHA256 signature: NOKEY, key ID c105b9de

If anyone has ANY thoughts or suggestions please feel free to reply, it would be much very appreciated!
Thanks in Advance,

Well I was unable to resolve those errors directly with compiling... However, we have another server with the same OS and everything that already had that package installed (which added more to my confusion why it wasn't working) so to just give it a try I copied that server's directory "/usr/lib64/gedit-2/plugins" to the one I was working on and now everything seems to be working just fine. All the plugins were able to be activated and they seem to work.!
The contents of the directory that I copied over were:
/usr/lib64/gedit-2/plugins # ll

And since all these plugins seem to be working without any issuse I guess the configure script was wrong about the missing requirements as I had thought...
Thanks anyways....!
