Re: Getting up and running with the Kinect in Ubuntu 12.04

Thanks for pointing that out, Antonio!

It seems version 0.1.2 is available in the current development release of Ubuntu (12.10 -- Quantal Quetzal). Version 12.04 ships with version 1:0.0.1+20101211+2-3 which is a snapshot from late 2010, I guess. I just found a PPA by Florian Echtler with up-to-date packages though. I'll try that and see whether it works!

Recent libfreenect can detach the kernel driver itself, we have this version 0.1.2 in Debian, but I don't know what version ubuntu is shipping.

Hi Erik,

Thanks for your comment!

I didn't mention those because I mainly looked at archival publications (full papers or notes). Nevertheless, it's indeed nice to see that participation at CHI by Belgian groups/researchers is increasing each year!

Heading a Belgian HCI group, this of course caught my interest: you seem to have not spotted our three contributions to CHI2012 though ;-) Seems like we're making some progress...

One of the core SimpleCV (http://simplecv.org) developers here. Just upgraded to ubuntu was happy they are packaged now, but seems not quite. Thanks for the help and mention for simplecv.

Thanks, Tom! It was a lot of fun, so if all goes well, I'll try to participate again next year.

Great write-up. Better luck next time!

You're very welcome! I mostly wrote this post to document how to get libfreenect to work on Ubuntu, so I wouldn't forget myself :) I'm glad you got it to work eventually, at least it's easier to work with libfreenect on UNIX systems than on Windows :)

Thank you so much for figuring out the "Could not claim interface on camera: -6" problem Jo. I have been fighting this problem for a couple of weeks and searching blogs and help sites and nothing I ever tried worked. I had tried "sudo modprobe -r gspca_main" but it wouldn't execute the command because it said gspca_main was in use. I had not found anything that stated you had to do the "sudo modprobe -r gspca_kinect" as well ... and to do it first! This instantly solved my problems, and freenect-glview works now. I had tried creating a blacklist, but the person whose instructions I was following said to blacklist "gspca_main" not "gspca_kinect". When I did so, it actually prevented my Ubuntu load from booting up! I have a dual boot set up where I can boot to Windows7 or Ubuntu 11.10, and after setting up the blacklist of gspca_main it would just sit and spin while trying to load and never come up. I had to boot to a sort of "safe mode" and remove the blacklisted file to get back up and running.

That piece of code tries to load the OpenCV 1.0 library. This might not work with newer versions of OpenCV.

tried the code from this
blog. In the second line it's given: "from CVtypes import cv". I even
downloaded CVtypes and pasted it in the same folder where the program
is. Even when I type "from CVtypes import cv" in interpreter mode, it's giving the same error. There is one thing about the "Wrappers" that I don't seem to follow. Here is the error: ">>> from CVtypes import cv Traceback (most recent call last): File "<stdin>", line 1, in <module> File "CVtypes.py", line 38, in <module> _cxDLL = cdll.LoadLibrary('libcxcore.so.1') File "/usr/lib/python2.7/ctypes/__init__.py", line 431, in LoadLibrary return self._dlltype(name) File "/usr/lib/python2.7/ctypes/__init__.py", line 353, in __init__ self._handle = _dlopen(self._name, mode) OSError: libcxcore.so.1: cannot open shared object file: No such file or directory" Can't make anything out of it even when I tried to...</module></module></stdin>

Re: Thoughts on speed reading

Rex Tang — Thu, 29 Sep 2011 08:05:38 -0000

I've tried with free programs but features are limited. I've actually invested into a speed reading program and it was actually worth it. I've had a great improvement with
regards to my speed in reading. It's an investment that's worth it
since you get what you pay for.

cv.DestroyWindow("camera") should solve the problem with exiting the program.

Re: Anniversary lecture by Gerard ‘t Hooft @UHasselt

Deb789 — Mon, 29 Nov 2010 17:33:59 -0000

I find it fascinating that a leading theoretical physicist and Nobel laureate like ‘t Hooft is realizing the potential of fractals. I recently read in a Chinese site a paper on fractal black holes and information. The site is http://wenku.baidu.com/view/3e.... It is only now that I realize that the author of this paper is a close friend of ‘t Hooft. It speaks for ‘t Hooft that he is open minded enough to be persuaded by an expert in nonlinear dynamics to incorporate fractals and deterministic chaos into his work. Modesty and open mindedness are the true unmistakable signs of a great scientist.

IIRC, I was still using version 1.0 or 1.1 back then.
