Transiting from Heathrow (LHR) to Newark (EWR) to La Guardia (LGA) to Toronto Pearson International Airport (YYZ) I have a valid Canadian Study Permit - Visa and will be travelling to Toronto Canada this summer via British Airways and I've booked and paid for my flight ticket, which has 2 connections from Muritala Muhammad Airport in Lagos to Heathrow Airport London and to Newark Liberty International (EWR) to LaGuardia Airport (LGA) in order to board my final flight to Toronto. My question goes thus: do I need a Transit Visa to board the US bound plane from Heathrow to Newark International and transiting from Newark Liberty International to LaGuardia Airport to board my last flights to Toronto?
Do I need a US visa to transit (or layover) through an American airport? In Europe usually you don't need to go through immigration to change planes (unless you are entering/exiting Schengen). Is it the case in the US as well? May I catch a connecting flight on one of the US airports if I don't have US visa?
ISP blocking port 25 indentation of a whole paragraph My problem is that I would like to write something like in LaTeX:   But I can't seem to do it wihtout reading like:   Which is pretty anoying to do all the time, in the middle of writting. Is there a code to do it for a whole paragraph without written \hspace*{1,5 cm} in middle of a sentence I have two partitions, one of them has a file system and the other is unallocated.  How to merge two partitions? I read this book in the mid-nineties, probably written in the 80s or 90s.  It’s set in the near future, where the world has experienced a sudden glaciation.  Most of the United States and Europe is now covered with ice.  Civilization has collapsed for the most part. The protagonist is a drifter with strange-colored eyes (yellow, I think).  Because of his weird eyes, he’s never really fit in anywhere.  He moves from place to place just trying to survive, but somehow he discovers that the new ice-age did not occur naturally.  It was engineered by extraterrestrials, to make their work easier.  They’re looking for the plans for a super-weapon - a weapon that can cause any star to go nova.  A rival group of aliens hid the plans for this weapon by encoding the information in the human genome millions of years ago.  The marker to identify humans who carry this gene is - you guessed it - yellow-colored eyes. What is wrong with using inline functions? While it would be very convenient to use inline functions at some situations,  Are there any drawbacks with inline functions?  Conclusion:  Apparently, There is nothing wrong with using inline functions.  But it is worth noting the following points!   Overuse of inlining can actually make programs slower. Depending on a function's size, inlining it can cause the code size to increase or decrease. Inlining a very small accessor function will usually decrease code size while inlining a very large function can dramatically increase code size. On modern processors smaller code usually runs faster due to better use of the instruction cache.  The speed benefits of inline functions tend to diminish as the function grows in size. At some point the overhead of the function call becomes small compared to the execution of the function body, and the benefit is lost  There are few situations where an inline function may not work:   For a function returning values; if a return statement exists. For a function not returning any values; if a loop, switch or goto statement exists.  If a function is recursive.   The __inline keyword causes a function to be inlined only if you specify the optimize option. If optimize is specified, whether or not __inline is honored depends on the setting of the inline optimizer option. By default, the inline option is in effect whenever the optimizer is run. If you specify optimize , you must also specify the noinline option if you want the __inline keyword to be ignored. Gamma Distribution out of sum of exponential random variables I have a sequence $T_1,T_2,\ldots$ of independent exponential random variables with paramter $\lambda$. I take the sum $S=\sum_{i=1}^n T_i$ and now I would like to calculate the probability density function.  Well, I know that $P(T_i&gt;t)=e^{-\lambda t}$ and therefore $f_{T_i}(t)=\lambda e^{-\lambda t}$ so I need to find $P(T_1+\cdots+T_n&gt;t)$ and take the derivative. But I cannot expand the probability term, you have any ideas? Why couldn't River Song's memories bring back The Doctor in the rebooted universe? In the season 5 finale of Doctor Who, in the wedding ceremony of Amy, River Song showed up outside the door. Moments later, we discovered that she gifted Amy her blank diary which was supposed to contain information about The Doctor. It means River Song remembered The Doctor.  Memories of The Doctor was able to bring The Doctor back to existence in the rebooted Spacetime. Why couldn't River Song's memories work? Formatting each part/section/subsection Are there some magic lines to be placed in the preamble that would, like in CSS,  specify how each generic section or subsection in the whole document should be formatted? Suppose I have a document with multiple include or input statements  \input{fileA} \input{fileB}   etc.   Is there an easy way to generate a single .tex file where \input{fileA} is replaced by the actual content of fileA etc. without copying it manually? How to create a custom UI? I was watching this  on making a custom UI tab using Python, and in the line from bpy.types import Menu, Panel, UIList, I see the names of objects that look like they can all be used to make different UI elements. Does bpy.types contain all the objects that people use when they want to make custom UI elements? I applied for a B1 visa to attend a conference in the USA in 2013. I had another nationality (Non- VWP) at the time and my B1 application rejected under section 306 of border security. I now can apply for ESTA under my new nationality. Can my ESTA application get approved? If not and I need to apply for visa is it every time I need to travel to stated or is it just the first time? VBA Hide Rows that contain N/A What does “pull sb. out of the hat” mean? I found the phrase, “pull her out of the hat” in the following sentence of the quote from Frank Bailey, the most relied-upon former aide of Ms.Sarah Palin, whose memoir, “Blind Allegiance to Sarah Palin: A Memoir of Our Tumultuous Years” is due out on Tuesday this week.  “I doubt if there's anything new in this book, just more detailed views of the gruesome story of her rise and fall. What would really be interesting is an account of who made the decisions in the GOP to pull her out of the hat. It certainly wasn't McCain.”  I don’t find the idiom, “pull one out of the hat” in any dictionaries at hand. Does it mean to “pick up” (Sarah Palinfor (vice) presidential candidate) or “remove her from (the candidate seat)? Can somebody teach me the meaning of this phrase? How does similar_text work? The origin of spin is some what a puzzle to me, everything spin from galaxies to planets to weather to electrons.  Where has all the angular momentum come from? Why is it so natural?  I was also thinking do photons spin? we always think of the wave as a standard 2d sin wave but could this rotate in 3d? What implications would this have?   And what about spacetime how does all the spinning effect?  This has always been avoided in all lectures and classes I ever went to. Given a pointed category $X$, is $|N(X)|$ contractible ($N(X)$ is the nerve of $X$)? Or are there counter-examples? Capacitor discharging through no load? What exactly would happen in the ideal case where a capacitor were to discharge into a wire with zero resistance?  Like in here:  There is still charge on one plate of the capacitor, which will try to go to the other plate to make $\Delta V = 0$ across the capacitor, so there has to be a current $I$.  But as more charge goes to the other side of the capacitor, the more repulsion these will cause to more coming towards them. So I am assuming current cannot just be constant?  I am starting from $$ I = C \frac{dV}{dt}, $$ but I know neither $V(t)$ nor $I$. Why is my find not recursive? I am running the following command, but it is not performed recursively:  find . -name *.java   I know there are java files further down in the current directory but it is performing the find on the current directory only. I am using OS X, 10.9. How to insert a figure between two texts? I'd like to create something similar to what is give below: text on either side of a vertically centred image: Can the jQuery UI Datepicker be made to disable Saturdays and Sundays (and holidays)? I use a datepicker for choosing an appointment day.  I already set the date range to be only for the next month.  That works fine.  I want to exclude Saturdays and Sundays from the available choices.  Can this be done?  If so, how?
