I am running Ubuntu 14.04. When I run   sudo apt-get install gazebo2   apt-get complains it cannot find libsdformat(&lt;=2.0)  apt-get doesn't provide libsdformat(&lt;=2.0), so I have built libsdformat1.4 from the source.  How can I make apt-get find a dependency I have built myself?
Being an early adopter and using 11.04 daily builds I sometimes meet a situation when some packages require earlier versions of other packages than those I have installed. Usually newer (but refused) versions of needed packages provide all the functionality of their older versions.  If I use dpkg -i --force-depends-version to install dependent packages everything works fine, I've never seen a problem.  Instead of manually downloading and installing every package, can I just make the system pretend there is a specific package version installed when there is a newer? Or is there a --force-depends-version key equivalent for apt-get?
Is there a conventional wisdom to what gear a bike should be left in, when used infrequently? In what order should the Star Wars movies be watched? Please don't lynch me, but I've never sat through an entire Star Wars film. I'm aware that the 3 (new) films are technically prequels, but I feel strange watching 3 new films then 3 old films?  Do I need to watch the new ones then the old ones? Adobe Reader and xcolor within a table breaks the line render I'm using the xcolor package to colour the top row in a table. This is displayed properly using PDF viewers such as Preview or Skim (Mac). But using Adobe Reader 10.1.3 (either Windows or Mac) doesn't display the table line properly.   But removing the colouring for the table fixes it. Here is the example that works as expected:  \begin{table} \caption{Table showing Feature 5's Functional Tests} \hspace*{-0.5in} \begin{tabular}[h!]{|p{0.6cm}|p{4cm}|p{5cm}|p{4cm}|p{1.5cm}|} \hline {\bf Test ID } &amp; {\bf Task } &amp; {\bf Expected} &amp; {\bf Actual} &amp; {\bf Outcome} \\ \hline    5.1 &amp; Something &amp;  Something &amp; Something &amp;  Success \\ \hline    5.2 &amp; Something &amp;  Something &amp; Something &amp;  Success \\ \hline    5.3 &amp; Something &amp;  Something &amp; Something &amp;  Success \\ \hline    5.4 &amp; Something &amp;  Something &amp; Something &amp;  Success \\ \hline \end{tabular}  \end{table}   And here is the example with a coloured row:  \begin{table} \caption{Table showing Feature 5's Functional Tests} \hspace*{-0.5in} \begin{tabular}[h!]{|p{0.6cm}|p{4cm}|p{5cm}|p{4cm}|p{1.5cm}|} \hline \rowcolor{gray!25} {\bf Test ID } &amp; {\bf Task } &amp; {\bf Expected} &amp; {\bf Actual} &amp; {\bf Outcome} \\ \hline    5.1 &amp; Something &amp;  Something &amp; Something &amp;  Success \\ \hline    5.2 &amp; Something &amp;  Something &amp; Something &amp;  Success \\ \hline    5.3 &amp; Something &amp;  Something &amp; Something &amp;  Success \\ \hline    5.4 &amp; Something &amp;  Something &amp; Something &amp;  Success \\ \hline \end{tabular}  \end{table}   Removing the \rowcolor{} command replacing it with \cellcolor{} creates the same view. Any idea how to fix this?  I've tried printing it out of Adobe and the lines print fine, but as this will be read on as a soft copy it's pretty important. .  Any idea how to fix this? Enable Careers and Jobs in app Universal type tranformer in Haskell Should OK button be on left of Cancel button or vice versa?   Are there any studies suggesting either of the solutions? Dual edge detector I am designing a hobby project that will run on a battery so I am trying to reduce power consumption. The SoC I am using has the ability to go into a deep sleep mode where it consumes very little power, and then can be interrupted by a falling edge on a pin.  I want to generate a high-low-high pulse when the state of a reed switch changes in either direction. I have been reading a lot and it seems that a one-shot monostable circuit can be built from a couple of transistors and an RC circuit to generate an output pulse when an edge is detected. I understand how that works. However, I can't figure out the best way to also pulse on the opposite edge.  One thought, was to just combine two one-shots that are configured to trigger on rising and falling edges respectively, and use the transistors at the output to pull the common pull-up low (kind of like a NOR gate).  Since I am a hobbyist, I am mostly using passive components. What is the "real" way of doing this in a low-power configuration using logic devices?  Edit: I figure I should mention something about the timing requirements. Normally the reed switch will be either open or closed for many seconds at minimum before changing states.  Edit: Here is an example of the circuit I was using for detecting only the falling edge:    And here is the ~20ms pulse it was producing for ~200ms button press simulating the reed switch (Channel 1 is Vbe for T1 and Channel 2 is measured at RST): What's wrong with this division?

I recently downloaded a torrent directly onto an external hard drive, (using a 2009 MacBook Pro and 1TB Seagate Expansion portable Drive) somehow during the download the drive was accidentally ejected, since this incident when I plug the drive back in it’s having problems reading.  The drive works fine for about 10 minutes, I can read/copy/paste and access files but then starts to wreak havoc; apps hangs, it hangs the Finder, etc.  I’ve tried repairing it in Disk Utility, which reads and repairs this disk but problems inevitably continue as described above.  I’ve deleted the Torrent file also. All my files on this external drive so re-formatting is not an option until I can retrieve them.
