If one had been to Iran after March 2011 but one's passport was replaced in the meantime, how risky would it be to visit the USA without mentioning said trip to Iran? Let me clarify there's no sketchy motives here. The reasons for the question are: 1) Avoiding a $160 visa fee; 2) Decreasing the risk of being rejected on entry, despite having a visa just because visiting Iran could raise flags.  To put it differently: is there any way of telling you've been to Iran other than having a stamp on your passport?
Now that  is in effect, people who have visited Iraq, Syria, Iran, or Sudan since 2011 are banned from entering the US under the Visa Waiver Program. However it's unclear to me how could the US officials prove one has set foot in those countries, unless:   There's a stamp in one's passport indicating so, which can be side-stepped by getting a fresh passport One mentions the fact on the ESTA application form, which is obviously easy to avoid   Is there any other way the US might be able to identify such individuals?  NB: I'm not eligible for the VWP myself and don't plan to travel to the four countries above, so it's a purely theorethical question
When Jedi lose parts of their body, does their midi-chlorian count and strength in the Force diminish? From what I understand, midi-chlorian count is a strong indicator of ability in the Force (though there are other factors as well). So it seems like when Anakin loses his arm or Luke loses his hand, their midi-chlorian counts (and thus their Force ability) should slightly diminish.  Is this the case? How to combine bold and "code sample" in Markdown? How can I make a word in a code sample bold? I only see asterisks around the expected bold text.  sample **sample** sample new array.sty and colortbl.sty incompatibility? I've used "//" and "\" to create this "W", and have made them into outlines, as I'm trying to give the different layers a colour, as well as having a white space where the lines touch and I would like to remove the top of the second "\".   I'm struggling with the white space at the moment and now I've added a stroke, the fill has decreased. Is there another way I could do this?   I've also tried to use my pen tool to remove the top of the "\" but when using "Path Finder" I cannot find an option to "Minus Forward". I'm a newbie so any advice would be lovely :) Why isn't $\mathbb Z [\sqrt{pq}]$ a factorial domain This is exercise 8 on page 147 of Jacobson's Basic Algebra:     Let $p$ be a prime of the form $4n+1$ and let $q$ be a prime such that $ \left( \frac{q}{p} \right) =-1$. Show that $\mathbb Z[\sqrt{pq}]$ is not factorial.   Here, $ \left( \frac{q}{p} \right) =-1$ means that $\overline{q}$ is not a quadratic number in the field $\mathbb Z / (p)$.  In the special case when $p=5$ and $q=2$, $9 = 3 \cdot 3 = (\sqrt{10} +1 )(\sqrt{10 }-1)$, with $3$ and $\sqrt{10} +1$ or $\sqrt{10} - 1$ nonassociates. But I have no idea what can I do with the general case.  I know that primes of the form $4n+1$ can be written in the form $m^2 + n^2$ with $m,n \in \mathbb Z$. But when $q$ is odd and not of the form $4n+1$, $pq$ is not the sum of two quadratic numbers. How can I use the fact $\left( \frac{q}{p} \right) =-1$?  Thanks~ How to set BibTeX bibliography title?

How to prove the following expression does not depend on x? I'm not sure how to approach this question, but I know it has something to do with taking the derivative of this. Can anyone please help me out?  Let x > 0. Prove that the value of the following expression does not depend on x: $$\int_{0}^{x}\frac{1}{1+t^4} dt + \frac{1}{3}\int_{0}^\frac{1}{x^3} \frac{1}{1+t^\frac{4}{3}} dt$$ How to transfer between International T2 to Domestic 1B terminals in Mumbai? I will be arriving in Mumbai Terminal T2 on a Turkish Airlines international flight. I have a separately-purchased IndiGo ticket 5 hours later from Terminal 1B (Domestic). In the past I heard of a free bus to transfer.    Is that still the case and if not how do I get to Terminal 1B from Terminal 2?

How does a phonon cause two electrons to attract each other and form a cooper pair? We know that like charges repel each other. But my professor claimed that two electrons can attract each other as well. What he said was that due to screening an electron travelling at some speed won't repel another electron, but that they will, in some cases, attract each other due to weak phonon exchange. What does that mean? What is phonon exchange? Do two electrons really attract each other? How can I get CSS comments with jQuery? I am wondering how I can read CSS comments out of a linked stylesheet.  I have this sample CSS loaded via:  &lt;link rel="stylesheet" type="text/css" media="all" href="test.css" /&gt;   &nbsp;  #test1{ border:1px solid #000; } #test2{ border:1px solid #000; } #test3{/* sample comment text I'm trying to read */}   I'm testing this in FF3. The following javascript reads the rules but doesn't read the comments in#test3.  window.onload = function(){     s=document.styleSheets;     for(i=0;i &lt; s[0].cssRules.length;i++){         alert(s[0].cssRules[i].cssText);     } } Automatically run commands over SSH on many servers There is a list of IP addresses in a .txt file, ex.:  1.1.1.1 2.2.2.2 3.3.3.3   Behind every IP address there is a server, and on every server there is an sshd running on port 22. Not every server is in the known_hosts list (on my PC, Ubuntu 10.04 LTS/bash).  How can I run commands on these servers, and collect the output?  Ideally, I'd like to run the commands in parallel on all the servers.  I'll be using public key authentication on all the servers.  Here are some potential pitfalls:   The ssh prompts me to put the given servers ssh key to my known_hosts file. The given commands might return a nonzero exit code, indicating that the output is potentially invalid. I need to recognize that. A connection might fail to be established to a given server, for example because of a network error. There should be a timeout, in case the command runs for longer than expected or the server goes down while running the command.   The servers are AIX/ksh (but I think that doesn't really matter. Comparing Arrays of Objects in JavaScript Wikipedia mentions several English words that have been :   Anime comes from animation and has been reborrowed into English to mean Japanese-style animation. Puroresu comes from professional wrestling and is a term for Japanese-style professional wrestling. Kosupure comes from cosplay (an abbreviation of costume play) and refers to the practice of dressing in costumes of anime and video game characters.

Creating a row for each value in a comma-separated string I'm currently trying to create a View from a Table that does the following:  Table A ╔═════════════╦═══════════════╗  ║ PART NUMBER ║   FILE NAME   ║ ╠═════════════╬═══════════════╣ ║  PN0001-01  ║      FOO      ║ ║  PN0002-01  ║      BAR      ║ ║  PN0003-01  ║    FOO,BAR    ║ ║  PN0004-01  ║  BAR,FOO,FOB  ║ ╚═════════════╩═══════════════╝   To create  View B ╔═════════════╦═══════════════╗  ║ PART NUMBER ║   FILE NAME   ║ ╠═════════════╬═══════════════╣ ║  PN0001-01  ║      FOO      ║ ║  PN0002-01  ║      BAR      ║ ║  PN0003-01  ║      FOO      ║ ║  PN0003-01  ║      BAR      ║ ║  PN0004-01  ║      BAR      ║ ║  PN0004-01  ║      FOO      ║ ║  PN0004-01  ║      FOB      ║ ╚═════════════╩═══════════════╝   So, essentially, I need to take records from Table A and insert them into View B, where if the record from A has a LIKE '[,]' property, then that field is split into multiple records in B, depending on the number of times the ',' is present, with the text between each ',' being given its own record in View B.
