I have a table top computer "Inspiron One" from DELL. I do not know the model number. It has the computer integrated into the large display screen with two feet in front and one in back. The keyboard and mouse are blue-tooth devices (i.e. they use radio rather than wires to talk to the computer). I can see that the screen has a camera lens at the top. When we first got it, the person who installed the computer was able to use Skype to talk to other people. So I presume that the camera worked with Skype at that time. However, I have not been using Skype and the software appears to be obsolete at this time. I would like to be able to use the camera to take pictures of myself and other people who visit here for possible use on Facebook, but I do not know how to do that. I have not been able to find any instructions on how to use this camera. Does anyone know where to look for them? Thank you. JRSpriggs (talk) 05:15, 11 March 2014 (UTC)
This is from China. The question is what's the difference between the word font AvenirLTStd-Black and Avenir-Black? And what's the LTStd stand for?Tiankong411 (talk) 06:39, 11 March 2014 (UTC)
Like many people, I use libjpeg for reading JPEG images into my C++ code. I've noticed that it doesn't seem to take note of the EXIF flags that specify the orientation of the image. I can't seem to find a way within libjpeg to either tell it to pay attention to the flag and load the image the right way up...or to read the flag myself and re-order the data.
Since the documentation of libjpeg is kinda sparse, I'm having a hard time figuring out how to do this.

I access the internet from two different Verizon DSL accounts in the NE US. Forthe last 10 days, between ~6PM and midnight the connection to Wikipedia, and only Wikipedia, over either account, in two different states, has been incredibly slow, often freezing entirely. This is the case on two different computers, using three different browsers. No other site is slowed or freezes. Could this be an issue with Wikipedia, or something to do with the recent net neutrality ruling? I am confounded. Thanks. μηδείς (talk) 22:45, 11 March 2014 (UTC)

There seems to be some issue noted by admins and others affecting the NE US for the last week, see the two discussions at the teahouse. μηδείς (talk) 06:26, 12 March 2014 (UTC)
Our article on Backdoor (computing) could use some attention by our more technically savvy editors. Please add it to your watchlist. Thanks! A Quest For Knowledge (talk) 23:10, 11 March 2014 (UTC)
