[04:03] <bill_> someone know how to login this irc software, 
[04:04] <bill_> I need to have off-lined feed back info 
[07:48] <gnrp> bill_: What do you need?
[07:49] <gnrp> bill_: Sorry, I don't understand your problem
[07:49] <gnrp> bill_: Sorry, I'm not a native speaker, so my understanding is limited. I suppose you want to read answers in an IRC chat even when you are offline?
[08:15] <bill_> @gnrp thanks for your response
[08:16] <bill_> I have not use the irc for very long tine
[08:16] <bill_> I forget how to login to it
[08:17] <bill_> currently the bill_ is my PC's username 
[08:22] <KBar> bill_: never reveal your credentials over Internet. You could be a target now, since someone knows your username, IP address. 
[08:23] <KBar> bill_: check out these guides and articles: https://help.ubuntu.com/community/InternetRelayChat & https://libera.chat/guides/basics
[08:23] <gnrp> KBar: To be fair, you see the username and address of most people when they log in anyway... ;)
[08:24] <KBar> gnrp: yes, but not the username on their PCs.
[08:24] <bill_> @KBar thanks
[08:24] <gnrp> KBar: Depends on the client. But whatever
[08:25] <bill_> @KBar I will try to strengthen my firewall
[08:25] <gnrp> bill_: If you want to login to IRC, you need to register with nickserv or with libera, respectively. But that is only required when you want to protect your nick
[08:25] <KBar> gnrp: I don't understand your point. No matter how you feel, it's not a good idea to say "hey guys, this is my LOGIN TO MY PC. and here is my password".
[08:25] <KBar> Anyway, this is not the right channel for such discussion.
[08:26] <gnrp> otherwise, not caring about login would also be ok. If you concern is how to read messages when you are offline, then look up IRC bouncers. There are free services for that available as well
[08:26] <gnrp> KBar: indeed
[08:26] <bill_> @gnrp I remember I did have register before with email address and password
[08:26] <KBar> bill_: you can join #libera for questions.
[08:27] <gnrp> bill_: Registrating to libera at least is only required if you want to have ea protected nick (i.e., nobody can take that nick when you are online) or if you want to join certain channels that only allow registered users inside (often done for spam protection)
[08:27] <bill_> Libera is very new, 
[08:27] <bill_> I dont have it previously 
[08:28] <gnrp> bill_: Check out https://libera.chat/guides/registration
[08:28] <gnrp> this tells you how registration etc. is handled in libera
[11:42] <bill_> hello to All here, I come back
[11:42] <KBar> welcome back bill_ how can we help you?
[11:49] <bill_> I have 2 Ubuntu, one is Ubuntu 18.04 and anther is Ubuntu 20.04,  
[11:50] <bill_> the Ubuntu 20.04 is XUbuntu desktop 
[11:50] <KBar> bill_:  that's awesome. 
[11:50] <bill_> I found they have different default sudoer setting internally
[11:51] <bill_> I do nothing in /etc/sudoers in the both machine
[11:52] <KBar> bill_: that's possible since their versions differ.
[11:54] <bill_> I create /tmp/t.sh: #!/bin/sh
[11:54] <bill_> echo $HOME
[11:55] <bill_> on the both machines
[11:55] <bill_>  run "sudo /tmp/t.sh" on the both 
[11:55] <bill_> the result is different
[11:56] <bill_> for 18.04 machine, the result printed is: /home/bill
[11:56] <bill_> on the 20.04 machine, the result is: /root
[11:57] <bill_> I know the principle of sudo 
[11:58] <bill_> I am thing they should document us for that change as in a list
[11:58] <bill_> I have use them so long time, and just start to know that
[12:00] <KBar> bill_: updates come with changelogs. Check /usr/share/doc/sudo/changelog.Debian.gz or 
[12:00] <KBar> similar files
[12:06] <bill_> no info about that , decided by search "home" string
[12:11] <KBar> bill_: probably documented somewhere upstream
[14:27] <melodie> hi
[20:33] <xu-irc66w> Hi
