@Mateo you around?

Mateo

@hbdgaf yep

hbdgaf

@Vader unicode

@Mateo so i was thinking about how many of the moving parts for this thing sound like a user-mode rootkit...

what language are you using it in.. that doesn't look like any sublimetext i've ever seen...

Mateo

@hbdgaf so would it detect as malware or something?

hbdgaf

no. it's just amusing how similar it is.

Vader

@hbdgaf what cab I do about it?

hbdgaf

00:31

install font packs for the languages you are using...

Mateo

@Vader are you using a language other than english on it?

Vader

nope

Q: Error loading shared library libSDL-1.2

I've compile ToME 3 game but I can run it, I've got: tome3: error while loading shared libraries: libSDL-1.2.so.0: cannot open shared object file: No such file or directory I have installed libstd1.2 both devel and runtime packages. I have that library $ ls /usr/lib/x86_64-linux-gnu/libSDL* /...

hbdgaf

@Vader there's a unicode or foreign character in the mix somewhere... it's in the file-open dialog, so it's probably in a file-name. the buttons getting hit is weird, but not altogether inappropriate.

Vader

okay thanks

Mateo

01:09

@Vader hm, I'm not sure how to use that plugin, any pointers?

was trying to run it to see if it worked here

Lucio

does somebody here use facebook?

The horrible fb like button wants to set me user to get the horrible code.

developers.facebook.com/docs/plugins/like-button

I prefer to destroy it.

But if someone have a functional code, let me know.

hbdgaf

01:27

boo - finally found a source for a song i've seen everywhere youtube.com/watch?v=LdpmOwGO-TY&list=RD9z1PztsGvE8

Lucio

@hbdgaf you always scaring me with your songs :)

hbdgaf

what? it's a good song.

Lucio

I'm listen, I'm..

hbdgaf

there now you can be scared

Lucio

wait, it is a remix

ciao

hbdgaf

01:29

yes. the entire playlist is cryptex remixes. he's a glitch artist that does a fine job of mashing things together and making it all awesome...

@Lucio later

Braiam

@Lucio use as dev, right? and... umm.... I don't think there's alternative...

Nathan Osman

02:06

Lightworks isn't half bad, actually.

hbdgaf

I've heard some rave reviews. Anything in the OSS/FOSS sphere that gets a "not bad" is a win in my book.

I'ld really rather see the features of lightworks in kdenlive though. I mean it's SOOO close already...

Nathan Osman

Not in my case - Kdenlive doesn't run on Windows yet.

Lightworks does.

Just uploaded this:

►

hbdgaf

do you have to have significant speed for the loop or are you using track-gravity?

also nice... but i'm an exclusively linux/bsd guy

Nathan Osman

No, you need significant speed.

There's no "artificial" gravity in this game.

Seth

@NathanOsman yet?

hbdgaf

02:14

@NathanOsman so world gravity, not track gravity. nice.

Nathan Osman

@Seth It's probably the single most requested feature.

And it should be able to be ported to Windows.

KDE libs are already available for Windows.

Seth

@NathanOsman Really? Wow. I agree, it should definitely get ported, it would be the best free video editor for Windows (besides maybe lightworks)

Anyone used zoneminder?

hbdgaf

nope

i have a friend that was wanting something to watch his yard for him though... is it light enough to run on a pi?

Seth

@hbdgaf That's one of the things I wanted to know.. Was thinking about using the pi + pi-cam + zoneminder.

'course I don't have a pi.

hbdgaf

i have a pi, but no external cams... only built-ins on the laptops

Seth

02:18

@NathanOsman btw, when you said you couldn't get a webcam to work with the pi, are you sure you provided the pi enough current to one the cam + anything else you had plugged in?

Webcams can use a lot of power..

Nathan Osman

@Seth I have a really powerful power supply for the Pi.

hbdgaf

defs... all reports indicate if you want anything to work with a pi, you should use a powered hub.

it takes the pi power out of the mix

Seth

@NathanOsman ok

Nathan Osman

...and it was working. Just slowly.

Seth

@hbdgaf as in run the pi off a hub or the webcam off a hub off the pi?

hbdgaf

02:19

all peripherals off the hub. pi on whatever source.

Mateo

I think it was the graphics that was the bottleneck on getting a regular camera going on the pi

Seth

ah.

Nathan Osman

I also have a portable lithium-ion battery for the Pi. 12,000 mAh.

Seth

just one more thing I would need to buy :-/

but of course, I want to use the pi-cam, so I'm hoping it would get more than 5 fps.

hbdgaf

These seem neat overstock.com/Electronics/…

Mateo

02:21

@NathanOsman I have a 4 AA to usb pack ;)

Nathan Osman

@Mateo But that... won't provide constant voltage...

Seth

>.< the bridge.

Nathan Osman

As the batteries are expended, voltage will drop.

@Seth I know :P

Seth

@NathanOsman this --^

Nathan Osman

I just got a flag.

Seth

02:22

me too

hbdgaf

@Seth buy them from wherever, it's just the first google shopping result i saw that looked right. i'm waiting for someone to make nipples for those so you can pop them in to an enclosure with no reference to orientation.

Nathan Osman

@hbdgaf What are we talking about?

Braiam

yeah, was from the bridge... someone validate it with a mod there...

hbdgaf

@NathanOsman scroll up. the usb tube battery type

Nathan Osman

Ah, missed that.

The battery I bought is fairly cheap and works amazingly well.

Let's see if I can find it...

hbdgaf

02:24

the beagleboard battery pack performed well for me

Nathan Osman

amazon.com/15000mAh-Portable-Ultra-High-Capacity-External/dp/…

It's even on sale.

(Mine was the 12,000 mAh model, but this is better.)

Seth

@hbdgaf that particular one wasn't especially powerful though..

Nathan Osman

Mine will power a car :P

Braiam

@NathanOsman someone seriously should make amazon oneboxing smaller...

Seth

@NathanOsman $50? You got to be kidding me.

hbdgaf

02:25

3

Nathan Osman

@Seth Nope, it's an amazing bargain.

Seth

@NathanOsman perhaps..

Nathan Osman

It'll charge anything via USB. And it has more than one USB port.

Seth

It doesn't matter what it can do, I don't have $50 to spend on something like that...

hbdgaf

i was more thinking something for hobbyist boards and no cables... so you'ld have a flat piece of plastic with some pads and a couple of slots for tubes or whatever form factor you prefer.

Seth

02:28

@hbdgaf that is a cool idea.

hbdgaf

way cheaper and disposable-ish

Nathan Osman

Let's do some math: the Pi uses 5V and under light use consumes about 500 mA. That's about 2.5 watts.

Unfortunately, I don't know how to get watts => watt-hours.

(My knowledge of electric current is limited.)

:(

hbdgaf

converting power consumption over time and milli-amp-hours so he can tell you how long the pi would run on that thing...

Nathan Osman

I'm trying to figure out the power consumption needs of the Pi.

(I have no idea what I'm doing now... I need to re-read my electricity e-book that I downloaded a while ago.)

On the plus side, Wolfram-Alpha is great for these sorts of calculations.

Seth

@NathanOsman ah.

hbdgaf

02:33

It's not that I don't think whatever power supply is enough to push the pi and something else... it's that I suspect a lot of the flakiness we see in peripherals powered from pi ports is sags in power as load changes for the pi and the peripheral

Seth

hmm.. I bet you're right. Especially if people buy cheap power.

@NathanOsman multiply watts x hours = watt hours (AFAIK)

hbdgaf

i think he mean watts to amp-hours

Seth

oh

probably.

hbdgaf

why he went to watts is beyond me though, since he started with amps, and batteries are rated in amp-hours.

here's a fun one if you're in to electronic music youtube.com/watch?v=yv769K2T6Iw&list=PL8B437430F86D7D37

Seth

technically, running your pi at full power (1A) should last for 12 hours on that thing I think.

@AmithKK I was talking about the 15000mAh one.. at full power :P

Mateo

02:40

and not just a workday ;)

hbdgaf

My workday is about 18 hours between the work I have to do and the work I want to do...

@Mateo Given lopping off 10% for safety, it's about one workday ;P

Amith KK

xD (No offence to IE users)

hbdgaf

shouldn't the opera circle be smaller?

Mateo

yeah, but they did jump to webkit....

hbdgaf

about time... took them long enough to catch on that developing your own engine is a bad idea

Mateo

02:45

it was good, but they kept trying to reinvent their own wheel.

Thomas W.

any of our moderators around? This post needs edit-locking (so that even the poster can't make changes)

Mateo

@ThomasW. wow "accepting answers" ?

Thomas W.

exactly.

Mateo

as if someone wouldn't if a solution worked...

Thomas W.

the fact they rolled back a MODERATOR'S rollback means the user is just... well...

kinda stupid.

my comment should help them realize they should stop though:

DO NOT edit your topic to add "[Accepting Answers]" again. Until this question has an answer marked as "Accepted" it is assumed you are accepting answers. Adding "Accepting Answers" to your title only bumps this thread, and you should not do that. (The fact that both me and a moderator have had to reverse this means that you should listen to this comment. Check the revision history to see what I mean by me and a moderator both reversing this change.) — Thomas W. 2 mins ago

unlike our moderators, I actually comment as to why i reverted the edit

especially when someone undoes a moderator's edit

(which usually means the user needs to be edit-locked so they can't edit their post like this again)

hbdgaf

02:48

I suspect bumping it was the intention. I don't think it had anything to do with... well... soilent green. IT'S PEEEPAAAL!!! yes possibly a dim OP

Seth

no mods around at this time.. of course :-/

Mateo

@hbdgaf spoilers! (kind-of since it is misspelled ;))

Thomas W.

well, i can flag the post for mod attention if needed, but i'll just keep an eye on that thread

hbdgaf

i do wonder if the tabakisp and OP accounts are related, now that it was bumped though... seems like an indicator to me

Thomas W.

well, if they ignore the comment, bad things, I guess, will happen

so meh

hbdgaf

02:53

just let them laze themselves for the airstrike. you pointed out the obvious bluntly enough.

Lucio

How can be plausible that a link does nothing??

FEichinger

@ThomasW. Oh for heaven's sake, they're still doing that?

Braiam

let it rain askubuntu.com/q/418349/169736

Lucio

@Braiam him should change "for future experience" to "for past experience"

Braiam

@NathanOsman watts = watt-hours / hours hence watts * hours = watt-hours so, 1 watt in 1 hour is 1Wh

or is it motto

Braiam

Motorola?

Lucio

lolllll

too much advertising for you ;)

@Braiam ~Moto en ingles se refiere al lema de alguien/algo

Braiam

04:05

meh...

Lucio

@NathanOsman do you know which of both is right?

Nathan Osman

Depends on context.

"Motto" is a slogan or expression that characterizes something.

"Moto" is a line of phones manufactured by Motorola :)

Lucio

@NathanOsman that one!

so, what is your Motto :P

Nathan Osman

A "motto" is usually associated with a product or company.

Firefox's motto is "rediscover the web" for example.

Lucio

> Don't be evil

Nathan Osman

04:10

Ubuntu's motto is "Linux for human beings".

Lucio

'nough said

Nathan Osman

@Lucio I know who uses that one... :)

Lucio

yep, the evil one.

Nathan Osman

I'm thinking of upgrading my PSU from 300 watts to 700 watts.

Then I'll throw in a decent video card.

Lucio

what is PSU?

Nathan Osman

04:24

Power supply.

(The thing that supplies power to the PC's components.)

Lucio

I don't have that, AFAIK.

But mine keeps working :D

Nathan Osman

In my country, a PSU takes 120V AC and converts it to various voltages for the components (typically 12V DC).

@Lucio You can't operate a computer without a power supply.

Lucio

@NathanOsman lol I see

@NathanOsman In my zone, 220V

Nathan Osman

Right, it's different in different countries.

Lucio

I can give you 50V if you want to :)

@NathanOsman I was lucky with that

Thanks to a client, got 600W for free.

Journeyman Geek

Mateo

@hbdgaf would be awesome, would be just perfect for the digital advertising

hbdgaf

oh @Mate pastebin.com/mnKumiyp

using v4l2-ctl and screenscraping until such time i write a reusable abstraction layer with python + C + Ctypes

Mateo

@hbdgaf ooo, listing the cameras?

hbdgaf

not completely done, but that was like - fine i'll screenscrape + 15 minutes. getting resolution options that way too... and rewriting the video marshaling to manually connect the pads in the pipeline so i can provide parameters for resolution and allow resolution selection (v4l2src uses max by default... which could be bad if you have a 1080p camera)

Mateo

12:54

ah, yeah- that much rez is pointless if you are squishing it down to under 1/4 of that size.

hbdgaf

yeah, and if you're doing multi-camera - there's no reason to force a video card to do that much scaling/eat that much RAM to hold the image buffer.

also, python-Xlib for python3 installs just fine via pip in a venv - tested it so we should be able to support 12.04

had to unbreak my venv/python3.4 mucking around to test it with 3.3

Mateo

@hbdgaf cool, that is what I installed with pip when testing the last snippet, right?

hbdgaf

might have been... seems like it was a "not in repo" and you installed it with pip globally. i tested venv so we don't step on anyone's toes on the "cluttering things up" note

i agree that everything in /usr should be from repo or ppa.

@Mateo - style question: scrape each command procedurally in the code or break it out in to a v4l2-ctl scraping wrapper? Do you think anyone would use it?

Mateo

the key commands?

hbdgaf

the camera management - get resolution, set resolution, etc commands

I mean, opencv basically says "camera management is your problem... not ours". might help nudge them in the don't be a d*** direction...

That and if I ever get around to wrapping it in Ctypes, I could do it incrementally instead of all at once

Mateo

13:08

oh, so things the camera would support

@hbdgaf so for the first would just do a limited set? and the second make a way of geting a dynamic set? am I understanding this right?

hbdgaf

yes. all of the stuff i was looking at doing with the hasn't been ported to python3 direct interface to v4l2 i have "sort of working" on my box. the direct interface probably shouldn't be ported until 3.4 is standard anyway because ctypes gets direct enum support in 3.4 anyway

@Mateo first screenscrape only the commands i use, but make it a class so people can use it other places instead of inlining the functionality. then maybe later when i'm doing the ctypes thing, replace a command invocation at a time as a function call.

hi guys... thoughts on the last 10 or so messages ^^

what it looks like now: pastebin.com/78aJiucG

Mateo

13:24

@hbdgaf I think it might be a handy tool - could it work to manage a device for a different camera program?

hbdgaf

yes...  it would be more like this:
class V4l2Dev:
  def __init__(self):
    pass
  def get_current_mode(self):
    pass

class V4L2Ctl:
  '''
  Convenience class to access V4l2 device configuration...
  '''
  def __init__(self):
    pass
  def devices(self):
    pass
  def get_mode(self, device):
    pass
  def get_modes(self, device):
    pass
  def set_mode(self, device, mode):
    pass

innards to be populated with things i'm already using and making it all class attributes so you can access it directly instead of with a bunch of function calls. then others could rip it out and reuse it instead of pasting in 3 lines.

anything you could reasonably push down to the device level would be and change device to =False to make it iterate over all devices in the case of a missing argument would probably make it a little more pythonic too.
