[20:30] I've been working on revitalizing the flavor, and have been the driving force behind some of the innovations in Ubuntu Studio apparent in 18.10. [20:31] it's ONLY been that long???? [20:31] I was gonna say [20:32] A lot done for the time frame. [20:32] Any questions for Eickmeyer? [20:32] I've been an administrator for the Ubuntu Studio Facebook and Twitter accounts as well. [20:32] I've been doing all webpage posts on ubuntustudio.org since April. [20:32] bashfulrobot: +1 [20:32] random question with no bearing on your membership: what's the future for studio? [20:33] Eickmeyer: How do you see yourself moving forward within the Ubuntu ecosystem? Plans? ideas? (high level) [20:33] Right now, we're focusing on bringing Wacom tablet configuration to ubuntustudio-controls, and making ubuntustudio-installer a utility that anybody can install from any flavor to gain all of the benefits of Ubuntu Studio. [20:33] That way, they can use thier desktop environment of choice. [20:34] OOOOH [20:34] Eickmeyer, any loco teams around? I am wondering why you are not involved into? [20:34] bashfulrobot: I see myself continuing the lead for Ubuntu Studio and brining it back into the spotlight of being the multimedia distro of choice. [20:34] nzoueidi: Currently, the loco teams in my area are inactive, afaik. [20:35] valorie would know more about that than I, however. [20:35] Eickmeyer: If you had to suggest one improvement for Ubuntu as a whole, what would it be? [20:35] i can confirm they are, afaik, too [20:35] there's been some talk of bringing ubuntu pnw back but i need to revisit that topic again, so blame me [20:35] DO IT :D [20:37] Eickmeyer: What do you see as on of the hardest things when getting involved in Ubuntu? [20:37] tsimonq2: Tough one. I'm not sure I have a concise answer to that, but I think figuring out a way to get packages from Debian updated easier would be nice, but I really don't know. [20:37] Cool. [20:37] Eickmeyer: What do you see as *one* of the hardest things when getting involved in Ubuntu? [20:37] I'm ready to vote as soon as bashfulrobot's question is answered. [20:38] tsimonq2: works for me. [20:38] me too, I need another mug of coffee [20:39] ditto [20:39] I am looking into the bugs in your LP account, keep it up [20:39] bashfulrobot: Probably one of the hardest things is finding a place where one's skills are best used. I have a degree in leadership, so I found a leadership opportunity with Studio once I saw the need. However, leadership spots seem hard to come by, which makes sense. [20:39] Honestly, it ended my days of distrohopping. [20:39] :-) [20:40] for now. Wait until your installer is out.

[20:43] Thanks nzoueidi [20:43] in fact, it's completely ridiculous [20:43] wxl: shush XD [20:43] xD [20:43] *throws @tsimonq2 back over to telegram* [20:46] * bashfulrobot looks up modulo [20:46] wait what? tsimonq2 that was odd [20:46] ha ha [20:47] i don't think he knows what he's talking about [20:47] in fact i'm sure of it XD [20:48] Yeah, I looked it up and cannot make heads or tails of what he meant. [20:49] the only thing i can think is perhaps he means is there anyone remaining that's not divided between the choices of supporting or not supporting it?
