How to enable Linux wifi hotspot for android devices

This is some trouble I faced. When I create a wifi hotspot from my laptop, I couldn't connect my phone to it.

Normally it allows when you create an open wifi hotspot, but with a password protected one you can't.

This is because Ubuntu based OS's create ad hoc wifi networks, and they are not compatible with connecting to other devices. We can fix this with a simple trick.

1. Create a new wifi connection

 This is nothing big, most of the Ubuntu based OS's have a GUI to do this via a network icon the top etc.
Remember create it as WPA & WPA2 Personal network. This is the type of the network that we're gonna create, and it allows you to set a password for that.

2. Make it accessible to other devices

 After you creating the wifi network it will create a file in the /etc/NetworkManager/system-connections/ directory

I created mine as mynetwork so here is the file I got. You might need sudo permission to access that.
The file is there, so I just wanna edit it so i'd open it up with my favorite text editor, and edit the line which has the attribute mode..

 I'm using gedit to show here, but i'd rather use vi.  

 $sudo gedit /etc/NetworkManager/system-connections/mynetwork

It'll open up the the file in the text editor. Find the line for the mode.


Replace the value adhoc with ap

Save it and close out the text editor. 

3. Start the wifi hotspot again and it'll be available for your android device!

VLC skins

It's been a while from my first blog post, so today I thought to make a blog post about skins in VLC player. I think you all are familiar with VLC player if not, here's the link for the website www.videolan.org/vlc/index.htm l In brief, VLC player is a free and opensource player that can play almost all the types of media formats. Even though it is a such a nice player, it looks kind of old and rusty, like the windows classic look. But you can make it prettier by just adding some new skins to it.  You can download skins for the player from here http://www.videolan.org/vlc/skins.php Then place the downloaded skin file (.vlt file) in the " skin " folder in the installation directory.           eg:- in windows:    C:\Program Files\VideoLAN\VLC\skins           or in linux systems:  ~/.local/share/vlc/skins Then, open the VLC player and go to the preferences. ...

Java, how to create a list with a single element

 I wanted to create a Java List with a single element. Yet, I wanted to add more elements later. So, I was looking for a couple of ways to do this. So far there are multiple elegant ways to create a list with a single element with a one-liner. Not so much for a modifiable list though. Here's what I gathered so far. Followings are a few ways of creating a list with strictly a single entry. Can't add more elements. 1. Collections.singletonList() This returns an immutable list that cannot be modified or add more elements. // An immutable list containing only the specified object. List<String> oneEntryList = Collections. singletonList ( "one" ) ; oneEntryList.add( "two" ) ; // throws UnsupportedOperationException 2.  Arrays.asList() This returns a fixed-size list consisting of the number of elements provided as arguments. The number of elements provided would be an array hence the size is fixed to the length of the array. // Returns a fixed-size list List...

Ubuntu DNS issue fix DNS_PROBE_FINISHED_BAD_CONFIG

Issue  I've been playing with a VPN and somehow it messed up my DNS resolution configurations. Chrome gives  DNS_PROBE_FINISHED_BAD_CONFIG  error and can't ping google. So it seemed to be an issue with the DNS. Of course, restarting didn't fix it. I tried DNS lookup which gave me below. To make sure this is somehting to do with my DNS confgis, I ran the same by providing the google DNS servers.  It works, which means my default DNS is not working for some reason. To make sure this, ran the below command. systemd-resolve --status Output has an entry for DNS Servers, which was  ::1 Fix 1. Edit the file /etc/systemd/resolved.conf. sudo vi /etc/systemd/resolved.conf 2. Add new DNS entries. I added 2 google DNS and the cloudflare DNS sever. [Resolve] DNS=8.8.8.8 8.8.4.4 1.1.1.1 3. Restart the systemd-resolved and check the configuration is persisted in /run/systemd/resolve/resolv.conf file. sudo service systemd-resolved restart cat /run/systemd/resolve/resolv.co...
