Reload sound driver in Ubuntu:
pulseaudio -k && sudo alsa force-reload
I've needed to do this on multiple installs far, far too often.
word = word.translate(str.maketrans('','',string.punctuation))
make sure the service is started:
sudo service mongod start
See ports in use:
sudo ss -plnt
Filter the list:
sudo ss -plnt | grep ':80'
Kill all proccess using a specific port, this will do so violently:
kill -9 $(lsof -t -i:5000)
no ethernet networking
not helpful but good for info
lshw -C network
sudo service network-manager restart
modified
/etc/NetworkManager/NetworkManager.conf
changed managed to true
changed it back
still no internet
lspci -nn | grep 0200
00:19.0 Ethernet controller [0200]: Intel Corporation Ethernet Connection I217-V [8086:153b]
this did nothing
sudo apt-get install build-essential linux-headers-generic
installed net-tools for ifconfig, why doesn't it have it by default?
it seems like it has the driver, that the driver works but that it just doesn't connect
upgrading ubuntu software packages to see if it helps
this seems to be the driver and this command checks it?
sudo modprobe e1000e
grep of log for adapter
dmesg | grep e100
log says it was renamed:
[ 0.943644] e1000e 0000:00:19.0 eno1: renamed from eth0
this might be the cause of the problem?
tried manually setting ip, netmask dns for ip4 for the adapter, tells me it's connected, guess what it's not connected
ethernet adapter is called eno1 for some reason
downloading driver from intel for
Ethernet controller: Intel Corporation Ethernet Connection I217-V
got the info on that from running
lspci
sudo apt install ethtool
get info on adapter
ethtool adapter_name
e.g. ethtool eno1
It is really intermittent though, in using Fedora the same computer has no problems with the network adapter. Like Ubuntu however the sound doesn't work for headphones which is a whole other annoying Gnome3 thing.
while sleep 1; do ls | wc -l; done
rm -r *.srt
ls -alh | grep '\.json$' | sort
Search all files for a specific extension:
find / -name "*.pdf"
Check the adapter state:
sudo lshw -C network
Make the network connection active:
sudo ifconfig eno1 up
Manually set the ipv4 setting for the ethernet adapter
sudo ifconfig eno1 192.168.0.15 netmask 255.255.255.0
Set the default gateway
sudo route add default gw 192.168.0.1 eno1
Set the defualt nameserver:
echo "nameserver 8.8.8.8" > /etc/resolv.conf
THE ABOVE IS BASICALLY ALL YOU NEED TO GET IT WORKING
i now get permission denied doing the above command even as root, permissions for the file resolv.conf are actually for anyone to be able to edit
lrwxrwxrwx 1 root root 39 Jul 1 23:03 resolv.conf -> ../run/systemd/resolve/stub-resolv.conf
so it's a little strange, looking at the file the nameserver is:
nameserver 127.0.0.53
so i'm changing it to: 8.8.8.8
so trying to save resolv.conf i get:
could not save file too many levels of symbolic links
a@a-Z97-D3H:/etc$ ls -al | grep resolv.conf
lrwxrwxrwx 1 root root 39 Jul 1 23:03 resolv.conf -> ../run/systemd/resolve/stub-resolv.conf
i have changed both files in: /run/systemd/resolve
to have a name server of: 8.8.8.8
These two are not that useful
lspci -nnk
lspci -nnk | grep -A2 net
Command to fix problem with wifi dropping on x200
sudo iwconfig wlp3s0 power off
get current driver info:
sudo lshw -c video
current driver:
configuration: driver=amdgpu latency=0
replace AMDs driver with MESA:
https://launchpad.net/~paulo-miguel-dias/+archive/ubuntu/pkppa
So folloing the advice in the above link i first purged and removed then did
sudo lshw -c video
and it's still using the same driver, so i don't think it's actually using the mesa driver at all
after re-adding the packages it still shows the driver as:
amdgpu
seems the right driver is installed you can check with:
glxinfo | grep "OpenGL version"
says mesa there
The mesa drivers are better but I am still getting graphical problems.
Use specific version of python:
mkvirtualenv -p /usr/bin/python3.6 env_name
you can link to any wikipedia page by an id
https://en.wikipedia.org/?curid=23251407
random number in this range seems ok:
232562
https://en.wikipedia.org/?curid=232962
get random stuff (doesn't only return articles):
https://en.wikipedia.org/w/api.php?action=query&list=random&rnlimit=5
one random article (CHAR LIMIT exchars=500):
https://en.wikipedia.org/w/api.php?action=query&generator=random&grnnamespace=0&prop=extracts&exchars=500&format=json
specify an article type (otherwise you get all kinds of non-article things like templates and talks) THE ORDER OF THIS SEEMS TO MATTER
&grnnamespace=0
https://en.wikipedia.org/w/api.php?action=query&generator=random&grnnamespace=1&prop=extracts&format=json
search for articles by a word (here the word is: meaning):
https://en.wikipedia.org/wiki/Special:ApiSandbox#action=query&format=json&list=search%7Calllinks&iwurl=1&srsearch=meaning
/w/api.php?action=query&format=json&list=search%7Calllinks&iwurl=1&srsearch=meaning
Request json: { "action": "query", "format": "json", "list": "search|alllinks", "iwurl": 1, "srsearch": "meaning" }
Adding origin=* fixes CORs errors for requests from localhost for this API.
Use a proxy service which just exposes one key to that service - this is basically like 3
call the API from the back end - i think that mashape is an API proxy? yahoo also run an API proxy where you can use third party proxies - I have found this to be a bit unreliable.
if the API allows it you can tell it to only allow traffic from one domain - this actually seems like the most reasonable approach.
Use env variables if you have a back end and access to the server.
