I tried to create a PC-BSD start up/install on my usb flash drive using dd to try dual booting with it, and now I am left with a USB with only 1GB available instead of 16GB.  The command I used was:  dd if=PCBSD10.1.1-RELEASE-01-31-2015-x64-DVD-USB.iso of=/dev/sdb bs=1M   I was advised on their forums to use bs=1M on linux instead of bs=1m in the PC-BSD manual.  Gparted only sees 1Gb now and there seems to be no way to re-format.  However, when I run startup disk creator on Ubuntu, it seems to see that it is a 16GB flash but has a red x indicating that I can't install to it, nor can I use the erase disk function.  Trying:  mkfs.vfat -I /dev/sdb   didn't help either.  Thanks.
I recently made my pen-drive bootable with Ubuntu 14.04. But I need to unboot my pen-drive now. I formatted my pen-drive once,But the size of the pen-drive still shows 2.25 MB. Whereas,this is an 8GB pen-drive. How can I get rid of this problem. I'm still using Windows 7.
Closure of a certain subset in a compact topological group When should I use velocity versus addForce when dealing with player objects? A lot of strange loop devices appear in my Kubuntu OS.

Easy way to change apache www location I have always argued adamantly, as long as the issue has been around, that gift should never be used as a verb. However, someone whose English knowledge I quite respect disagrees.  I’ve done some searching and I haven’t found a consensus; should gifting be shunned? Several airline and trip planning sites will allow you to check "I am flexible with my dates" or a similar option.  Is there any way to also search more broadly for location?  For example, if you wanted to leave from YYZ or YKF and arrive at any airport in California, can a search for such flights be done somehow?  I ask because when I plan plane trips, I want the lowest price.  I'm OK with leaving a day or two later if I save $200 (same with the return trip).  There are 3 airports within 80 km of me, I'll leave from the one with the cheapest flight. And I'm also OK with changing the trip to spend time exploring San Francisco instead of lying on the beach near San Diego, and that sort of thing.  Normally this would take dozens of searches, but I'd like to see it all at once. Is there a list of Windows special directories/shortcuts (like %TEMP%)? I'm looking for a reference list of shortcuts like %TEMP%.  When I'm using Windows+R or Windows Explorer and type %temp%, the Windows Explorer takes me to the Temp directory. Are there more of these shortcuts?  UPDATE: . T-SQL: Selecting Column Based on MAX(Other Column) What is the grammar behind "Thanks be to God"? What does "65" mean? What is port forwarding and what is it used for? There are a lot of questions on , but there doesn't seem to be one that clearly states what it is and what it's used for. So:   What is port forwarding? What is it used for, and why would I need it? What exactly is a photon? Neatest proof that set of finite subsets is countable? Does disabling root login enhance security? If virtual particles sometimes add more mass/energy to a system then was inputed or comes out in the output, how do they not violate conservation of mass/energy. Could there be a bit of reputation leakage between the sites, please? Is there a way to check if a file is in use? Earlier this year, I read a huge (1000+ pg) novel about a cloistered group of monks that sort of worshiped math. The story involved alternate dimensions or time travel or something. A big thing in the book was coordinates, containing data like for speed or something as an alternate axis. There were several rings of the monastery.   At some point the main character was called out of his monastery to never return. I'm hoping to figure out the name so I can discuss it with my book club. Prove the following inequality:   $$\dfrac{e^x + e^{-x}}2 \le e^{\frac{x^2}{2}}$$   This should be solved using Taylor series.  I tried expanding the left to the 5th degree and the right site to the 3rd degree, but it didn't help.  Any tips? As per the following example, and as in  In bash, where has the trailing newline char gone?, I want to know "why" it happens    x="$(echo -ne "a\nb\n")" ; echo -n "$x" | xxd -p  # Output is: 610a62  # The trailing newline from the 'echo' command #   has been "deleted" by Command Substitution   I assume there must be some very significant reason for a shell action, namely Command Substitution, to actually delete some data from the command output it is substituting... but I can't get my head around this one, as it seems to be the antithesis of what it is supposed to do.. ie. to pass the output of a command back into the script process... Holding back one character seems weird to me, but I suppose there is a sensible reason for it...  I'm keen to find out what that reason is...
