It seems like one-way tickets are always more expensive than buying round-trip. So I am planning to book a return ticket. For example I would like to go on the following itinerary this May. Myself &amp; my friend are planning to travel.  I have a valid visa for Malaysia and I am going to Vizag on May22nd using another itinerary and will return using below itinerary ( May 28th )   May 12th - Malaysia --> Vizag  ( wont do journey ) May 28th - Vizag    --> Malaysia ( will do journey)   My friend did not visit Malaysia yet, but if I booked below itinerary for him, could he do only the one way journey on May 28th ?   May 12th - Malaysia --> Vizag  ( wont do journey because never visited before ) May 28th - Vizag    --> Malaysia ( will do journey)
I'm looking to book flights from) Philadelphia (PHL) to Detroit (DTW). Direct flights are quite expensive. I noticed, in expanding a search to surrounding airports, that I can book from Allentown (ABE) to Detroit for far less, and the connection is through Philadelphia.  Can I book this flight but board in Philadelphia? I'll be traveling with carry-on luggage only, so on the return, it's obviously no problem. But would I be allowed through security and on to the plane in PHL with out having flown from Allentown?
What are the shell's control and redirection operators? $\mathbb Z_{p^n}$ is not the direct product of any family of its proper subgroups I'm trying to solve this question of Hungerford's Algebra book:     $S_3$ is not the direct product of any family of its proper subgroups.   The same is true of $\mathbb Z_{p^n}$.   The first claim is easy: we note that every subgroup of $S_3$ is of order $2$ or $3$ by Lagrange, since its subgroups are of prime order, they are cyclic, then abelian, but $S_3$ is not abelian, contradiction because $S_3$ is not abelian while the direct product of abelian groups has to be abelian.  My problem is with the second claim, I need help. Can less retain colored output? Can I get less not to monochrome its output?  E.g., the output from git diff is colored, but git diff | less is not. Looking for an appropriate English name to replace my Chinese name Background: I am Chinese, and after living abroad from China for several years, I realize that I need an English name anyway. I’ve seen too many confused faces looking at my Chinese name. My Chinese Name: I am male, my Chinese first name is (IPA): /ʃəʊ/-/dəʊ/, and my family name is: /dʒi/. (Check ipa-reader.xyz if not clear.) Any advice about what could be a good idea of a first name, if the last name sounds like &quot;G&quot;? Something about myself: I'm a introvert, nerdy person. I don't like social, small talk, public area. I enjoy programming, writing, arguing. Physically I am short, slim, with a huge glasses. I have a CSV file where one line looks like this:  Duration, user, lat-start, long-start, lat-end, long-end 298, Casual,38.9101,-77.0444,38.91554,-77.03818   Each row in the CSV has two points and I need to draw a line between those two points for each row.   How can I do this using QGIS 1.8.0?   I have tried using the delimited text file plug-in, but it just draws points and has no line option from what I can see. Transit Visa for Thailand Effect on loading a DC motor - load torque Could someone give a (detailed) explanation (perhaps with formulas) of how the load (torque) affects the armature current of a DC motor (separately excited or shunt or series)?  As the load torque increases the speed of the motor decreases, and assuming the terminal voltage stays constant, the EMF will become lower and thus the armature current will increase.  But could someone give me the formula that shows the relation between load torque and armature current?  Is it something like:   \$T_\text{developed} = T_\text{shaft} + T_\text{friction windage} + T_\text{load}\$ ,   where \$T_\text{developed} = K \, \text{flux}_\text{pole} \,I_\text{armature}\$ ?  But then you have  \$P_d = P_s + P_{f_w} + P_l   \$  where \$P_d = K \,\text{flux}_\text{pole}\, I_\text{armature}  \,\omega_m\$  In the last formula you can't see that as the increase due to \$P_\text{load }\$ the armature current increases because maybe someone can say the speed \$\omega_m\$ increases.  And how come at no-load the armature current and thus the torque developed is zero? Is it really zero, or do I have to assume there is some current flowing?  Could also explain me the principle of torque developed. Because at no load, the shaft torque is equal to torque developed, right? "Give him a box that everyone knows what it contains." "Give him a box that everyone knows what it contains."  Is this correct English? It sounds wrong to me. Where can I download Ubuntu 16.04? I am unable to find the link for downloading Ubuntu 16.04 onto my   desktop/laptop. I am able to see the link only for 18.04, but I need 16.04. Area 51 layout breaks when zoomed to 90% Can we get our personal voting data displayed on the Questions lists? There's been several times where I have been surfing the site, and noticed a question that I am not sure I've checked. Even if I've checked the question before, I can't recall off-hand whether or not I've voted on it or its answer.  Is there a way we can have our personal voting history reflected to some degree or another, in the Questions listing? For example, could there be an indicator as to whether or not we have already voted (up or down) on a question, and perhaps maybe an additional indicator as to whether we've up-voted any of its answers?  It would be very convenient to have some of this data available up-front, without actually having to view the question again. What does kill 0 do actually? In the man page, it says:  kill [ -s signal | -p ] [ -a ] [ -- ] pid ...  pid... Specify the list of processes that kill should signal.  Each pid can be one of five things:           0      All processes in the current process group are signaled   And I tried like this in bash:  $ man kill &amp; [1] 15247 $ [1]+  Stopped                 man kill $ kill 0 $ ps 15247 pts/41   00:00:00 man   Here 0 is used as pid. As I understood, kill 0 will kill all processes in the current process, which includes pid15247. However, it didn't do anything in this example. Does anyone have ideas about how to use it? Can't update drupal core to 7.27 True random generation in Java I was reading the Math.random() javadoc and saw that random is only psuedorandom.    Is there a library (specifically java) that generates random numbers according to random variables like environmental temperature, CPU temperature/voltage, or anything like that? I am using Ubuntu 12.10.  Please outline the different ways I can upgrade to 13.04. Deep Format of a Harddrive on a Linux System I've got an original Asus Eee PC Netbook that I'd like to sell.  When I've sold old computers in the past, I've typically done a deep/secure/zeroing out style format.  How can I do this on a Linux Netbook?  I'm looking for   The command that will let me do this Advice on how I can do this on a device with (seemingly?) non-removable media   Thanks in advance! $x^y = y^x$ for integers $x$ and $y$ is a dove a "she"? how to use "he" and "she" for animals? In the song &quot;Blowing in the Wind&quot; by Bob Dylan, there's a verse that reads:  Yes, and how many seas must a white dove sail Before she sleeps in the sand?  My question is, why he used &quot;she&quot; for a dove? What about other animals and other non-humans? Is there a general rule? Showing that $\Bbb R[x] / \langle x^2 + 1 \rangle$ is isomorphic to $\Bbb C$ question Why are we using the squared residuals instead of the absolute residuals in OLS estimation?  My idea was that we use the square of the error values, so that residuals below the fitted line (which are then negative), would still have to be able to be added up to the positive errors. Otherwise, we could have an error of 0 simply because a huge positive error could cancel with a huge negative error.  So why do we square it, instead of just taking the absolute value? Is that because of the extra penalty for higher errors (instead of 2 being 2 times the error of 1, it is 4 times the error of 1 when we square it).
