I'm running a custom version of raspbian on my raspberry pi, it has no X server running only in text mode with only basic services installed. i got a usb monitor that i want to plug in and use to show the console, i plugged it in it's detected and showing a green screen but i'm not sure what i can do to achieve my goal if that's even possible. Any of you can give some pointers ?  dmesg log:  [ 1606.712232] udlfb: DisplayLink LILLIPUT USB Monitor - serial #70873920033 [ 1606.724237] udlfb: vid_17e9&amp;pid_02a9&amp;rev_0130 driver's dlfb_data struct at b8d6d800 [ 1606.741459] udlfb: console enable=1 [ 1606.749754] udlfb: fb_defio enable=1 [ 1606.757827] udlfb: shadow enable=1 [ 1606.766183] udlfb: vendor descriptor length:17 data:17 5f 01 00 15 05 00 01 03 00 04 [ 1606.782954] udlfb: DL chip limited to 1500000 pixel modes [ 1606.794348] udlfb: allocated 4 65024 byte urbs [ 1606.885797] udlfb: 800x480 @ 59 Hz valid mode [ 1606.894588] udlfb: Reallocating framebuffer.

So I have a Palm Pre (original P100EWW) model that I enabled developer mode on, and installed a Debian Squeeze chroot.  Works great.  I have plans to use this for ANYTHING (bittorrent peer, web server) but a phone.  I noticed if I do a cat /dev/urandom &gt; /dev/fb0 it actually writes random pixels to the screen until a No space left on device error is generated.  Awesome, now I can use the display.  So what kind of utilites are there that will either A) let me use /dev/fb0 as a console I can output text to or B) render text on /dev/fb0 from the command line.  I don't know about recompiling the kernel for this yet (I'd love to eventually strip WebOS off entirely and turn this into a minimal ARM server) so userspace tools if they exist is what I'm asking about.  Also would prefer to render directly to /dev/fb0 and not use X.
How to implement a tree data-structure in Java? How can I check if the Active Object has a specific modifier so that when I run my code, it doesn't add the modifier again to the object? It should add the modifier only to the object which does not use that modifier. I have a 4GB DDR3 800Mhz recently I installed another 4GB. It turns out it's  DDR3 667MHz. Does it really matter I should own both rams 800MHz?    Slot1 shows recent RAM installation. ALSO I don't know if this is 1600MHz (it shows 800x2 and 667x2 for other) or just 800MHz ram. Let $ D = 2^\mathbb{N} $, i.e., D is the set of all sets of natural numbers.   What's the meaning of this definition? Intuitively, I would suggest that $ D = \{1,2,4,...\} $ but the explanation "set of all sets" leads me to the guess that this is wrong. My csv export displaying html, how to get rid of?

I'm currently using Debian 7 Wheezy, and I've noticed that the colors palette on terminal (which might be useful to identify among a large set of files and folders) are not enabled once I log as root.  Same, I've noticed the tab completion doesn't work the same in this situation.  How can I configure these issues? How to watch videos in Amazon Prime Instant Video? How to preserve custom number formatting after closing a workbook? I have created a custom format ##,##0.0,,, CTRL+J %% in Excel 2010 to display  10000 as 0.1 100000 as 1.0 1000000 as 10.0 10000000 as 100.0 100000000 as 1,000.0 and so forth.  The problem I am facing is that once I apply this format, save and close the workbook, the next time I open it the format gets changed by multiplying by 10 (100000 is displayed as 10.0).  I don't understand how it is getting changed automatically the next time I open it. However, when I apply other formats they remain unchanged. How to install PHP from source with latest cURL package on Linux? I simply have to use the latest cURL version (7.21.3) with PHP on my webserver. (Has to do with specific bug fixes)  It is not available by default on most current Linux variant repositories. (Natty Narwhal by Ubuntu is the only one and it's still in beta stages) - so I cannot simply run "aptitude install php5-curl" or similar to get it (the very latest version of cURL) installed.  How would one go about installing the very latest PHP + cURL packages?  Is it as simple as changing the to-download file for cURL in a repository somewhere? (ie. changing a text file's entry somewhere from  to  or something..?)  Basically I need the very latest cURL library running with PHP on Linux. How would you personally go about doing that?

Where can I download Windows 7 (legally from Microsoft)? I just bought a serial for Windows 7 on-line from the Microsoft store (the most painful shopping experience EVER!). I selected that I wanted to download my version of Windows 7 after purchase. After payment, I have listed a Product Key but no download link in sight.   Where do I download my Windows 7 ISO to burn to disk?  Note: I'm not a Technet or MSDN subscriber. More options when flagging for migration I think there should be more Stack Exchange networks available when flagging a question to be migrated. For example I'd think that the following question:    ...would be a better fit on unix.stackexchange.com instead of Stack Overflow. But without the option to mark it so, I feel hesitant to mark it. Disable flagging on old chat messages In response to the effect  is referring, I am proposing one of two possible scenarios:   Disallow flags on chat messages older than X hours, or Remove old flagged posts from the transcript, but no suspension occurs (as in the aforementioned question). I wonder whether it is possible to draw the three following quadric surfaces (cone, hyperboloids)  x^2+y^2-z^2=0  x^2+y^2-z^2=1  x^2+y^2-z^2=-1  (and the axis)   using pgfplots 3d or TikZ as it is done in the following image Space ship manned by only AI returns home to a different earth, back in time What do all those cryptic number and letter codes in a lens name mean?

In my native language, double negations "cancel out". I have been trying to learn English using movies and such things, but double negation confuses me. I see instances when double negation cancels out, and some when they do not.  For example, "I haven't got no money" is interpreted as "I have no money." "There wasn't anyone who didn't enjoy the party" is interpreted as "Everyone enjoyed the party."  Is this context dependent? If so, how does one decide which interpretation is correct? Quotient groups of D10 How do I find the groups D10/N where N is the normal subgroups to D10?  I know that the definition is aN for all a $\in$ D10. But I am unsure what the group, for example, D10/ D10 looks like? Any help would be much appreciated.
