SudoBike?!?!?!!!! I don't know what this is, but it sounds pretty neat! I sure do
<3 SudoRoom & SudoMesh, and bikes. Looking forward to having some time to
regularly visit again!!!
I've been saying how bad we need a folding bike over here biweekly for awhile, so if
there's no immediate use/room, I'd be ecstatic to house & attempt to upgrade
it for however long.
How often is the Sudo/Omni wish list is updated? In my nonexistent spare time, I would
love to make a little web app* that community users could update with various
needs/wants/haves. While I don't have much in the way of spare time right now, I do
have a lot of potentially useful "assorted randoms" on hand that I'd be
happy to contribute.
Miss coming by; hope to be able to come soon & check out all the amazing things
everyone has been up to.
Speaking of which- how does Sudo feel about field trips? I'm working part time with
an org who is teaching CS/Intro to Web Dev in public high schools. We are piloting in the
schools with the highest number of free & reduced lunches. In addition to our attempt
to bring CS education to economically marginalized communities, we are also attempting to
disrupt the tech divide and school to prison pipeline. One program is in Oakland this
semester.
We take field trips, and I think a hackerspace trip could be an invaluable experience to
include, along with all of the intimidatingly glossy, alternate universe style corporate
digs we will visit. I'd like to bring my class to Noisebridge, as it's a < 5
minute walk to there from school and NB allows field trips. However- nothing against NB,
I fully support them/think they're awesome, and these may have been totally isolated
incidents involving non members- I have some concerns due to past personal experiences
there. Since our classes consist largely of underrepresented minorities in tech
(including myself and the Oakland instructor), I might feel more comfortable bringing them
to Sudo/Omni, if we could arrange it.
Does Omni/Sudo have a field trip policy &/or has this ever happened? They are small
(20) classes of high school kids who are great to be around (and more respectful/mature
than a lot of adult, professional engineers I've met), so I don't think it would
be a huge burden on the space. Likely, our only ask would be a volunteer to show us
around and explain things. Figured I should ask before bringing up the possibility to any
of the other instructors.
So grateful for everyone's hard work in keeping this community (and similar endeavors)
going & growing.
best,
Elizabeth Biddlecome
*I do have something I made over the past couple of days, in the course of a Sisyphean
ordeal (I mean "job search process"), where I spend days without going outside
or adequate self care performing a lot of uncompensated work. I think I could actually
make this into a nice little SudoApp, without a ton of complications- plus I specified MIT
licensing, of course. On a personal note, it would great to direct at least some of the
massive amounts of energy expended throughout this frustrating hamster wheel process
toward a positive end. There may be/probably is something already in place for Sudo/Omni
that I don't know about, other than the wiki wishlist pages, IRC, here etc.
