We also have some Pis running Snappy. I'm think about making the students build arcade cabinets as a club project, but that's been done. What else could we do with Snappy?

jrg

@DonaldBrown Build them!

the reason I say build them is that while it's been done, it's still a challenge.

Particularly if they haven't done this kinda thing before.

user139252

Last semester they built "black boxes" out of them using wood I made them cut themselves and usb microphones.

user139252

Arcade cabinets could be a good next step.

user139252

5:30 PM

Neither of those projects, though, really used Snappy. They could have been done on any distro.

Terrance

That would be an awesome next step!

user139252

I was looking for something that really used the Ubuntu core

Terrance

We built an arcade cabinet at my old job when I worked for a game studio, and we put over 8,000 MAME games on it. Played extremely well. :D We used an old Metal Slug cabinet for it.

user139252

I work at a charter high school that's in the same parking lot as a Home Depot, so I always have them build everything out of wood :p

Terrance

@DonaldBrown You should too! Maybe have them build one for a Raspberry Pi arcade cabinet.

user139252

5:35 PM

That's what we're doing. Most creative design gets a $50 gift card to Best Buy. But, as I said, I also want to get them into using the Snappy core so that we can get into Snappy app development. Focus more on software development than just building cool things.

Terrance

@DonaldBrown That's really cool!

Good skills for them to have!

user139252

cough Any project ideas, then?

user139252

I'm stumped.

user139252

App development is hard to be original in.

Terrance

Any time I think of any, there is always an app that has already been made. :( I have done TONS of scripting for servers to detect different hardware and RAID levels. Take snapshots of them. Break the array, scrub the drives, then re-create the arrays so the servers can be redeployed ready to be reimaged, reused, etc.

user139252

5:46 PM

I could have them make an app version of that Yggdrasil board game.

user139252

Then make it work on lan

user139252

So Svartelfheim can actually battle against Asgard!

user139252

Good idea, Terrance!

Terrance

I think that sounds like a great idea for you Donald! Do it!!

jrg

6:42 PM

@DonaldBrown a better instagram kiosk.

I dunno. There's a bunch of different things you could do.

Terrance

Put it on the line.

:)

jrg

So these high school students are going to be the most experienced snappy developers out there.

I kind of want to see a drop target web file server - open webpage to snappy box and send/download files

Nathan Osman

[cough] NitroShare [/cough]

Mateo

@DonaldBrown Ooo, yeah a browser game that multiple players play through LAN would be awesome

@NathanOsman yeah, you just need to make a snap, then do a web portal to send stuff back out, would be amazing

Nathan Osman

I'm frantically working on the IPC component now.

It's nearly complete but I'm debugging a possible Qt bug.

...on Windows :P

Mateo

Oh, that and I would like to see a webcam streamer, the current webcam demo just takes snapshots

Which could make an easy diy boxcast

Oh, owncloud is on snappy on the pi now, extremely easy to setup

Fabby

@Mateo: confirmed not delivered... :(

Nathan Osman

7:35 PM

So I've got an idea for Kickstarter.

Fabby

Am I so wrong that this is a terrible answer???

Nathan Osman

A "selfie drone" - it hovers about 6 feet off the ground and follows you around, pointing its camera at you and snapping pictures when instructed.

Obviously it would need a sufficiently capable camera and battery, so making it airborne would be a bit difficult.

But these are all technical problems that we could solve, amirite?

Mateo

@Fabby aw, almost

Fabby

@Mateo :/ Is there anything you can verify from your side?

Mateo

Interesting trying to interpret an Italian tracking page

I'll email you what I have, maybe it is the online system getting ahead of it's self - I once had the usps site say they were out for delivery - when in fact they just put it on the truck and didn't send the trucks out because of snow

Q: Why does writing to this socket discard the read buffer (and is that really what's happening)?

Consider the following snippet: QTcpServer server; server.listen(QHostAddress::LocalHost); QTcpSocket clientSocket; clientSocket.connectToHost(server.serverAddress(), server.serverPort()); // ...wait for connection to succeed... QTcpSocket *serverSocket = server.nextPendingConnection(); serve...

@A.B. yessir, landed yesterday at midnight, having coffee right now and waiting for my buddy to come over to hang out

Fabby

@NathanOsman I used to be able to read C++ code...

I'm getting older!

Nathan Osman

I don't always ask questions on Stack Overflow, but when I do... they're always very, very specific :P

Fabby

@NathanOsman :D Do you ever get any very, very specific answers???

Nathan Osman

8:23 PM

Occasionally.

Terrance

I used to work with a ton of C++ programmers. I bet my buddy Evil would know.

Fabby

This looks like me asking a question on AU, then setting a bounty and then still no one finding a solution to the problem...

Nathan Osman

I based it off my bug report: bugreports.qt.io/browse/QTBUG-47073

Fabby

Ah!

@Serg Back home!

Q: how to set cpuset/cgroup.clone_children flag to 1

I am trying to set the cpuset/cgroup.clone_children to 1 so that whenever I create a cgroup, it should by default copy all values from the parent cgroup. Also I am curious if there is a way to copy all values from parent cgroup to a child cgroup. For e.g. if I created a cgroup like: sudo cg...

I can access my external. But the directory that I want to access is readonly and I can't access. I tired to change the ownership as well as permission but I can't do so. Any suggestions?

Fabby

8:55 PM

@psimeson Erm, very vague... Could you provide the link to your question?

Does that contain more info?

psimeson

@terrance Hi. I can access my external. But the directory that I want to access is readonly and I can't access. I tired to change the ownership as well as permission but I can't do so. Any suggestions?

@fabby I have anold HDD. I want to extract from file from this drive. So, I mounted it to my ubuntu machine using external HDD dock. I can see the directories but I can access files inside of those directories

Terrance

@psimeson Hi. Give me a few here. I am presently working on another project, but in a bit we could run a teamview so I can see it.

psimeson

@terrance sounds good.

@fabby : when I do ls Desktop I get ls: cannot open directory Desktop/: Permission denied

Fabby

@psimeson close all file manager windows, then run from a terminal: gksudo nautilus and try again!

Terrance

@psimeson I am going to go with @Fabby at the moment. I believe he is on the right track there. :)

Rebooting system. Back in a bit.

@Terrance Mail server, unix command etc... ;-)
