On June 5, I arrived at the airport in Frankfurt and intended to fly to my final destination, with an intermediate connection in Vienna. Because of not having a Schengen visa, I wasn't permitted to continue my flights and my passport was stamped as you see below. Fortunately, I was allowed to buy tickets bypassing Schengen zone and reach home. If I had known about the visa requirement beforehand, I never would have bought the tickets that caused so many problems. What the codes &quot;C&quot; and &quot;I&quot; in the rights below corner of the stamp mean and what are the implications of these codes?
I was held at the Polish borders when I attempted to enter by train. They took my fingerprints and sent me back with a written document. I respected the decision and returned immediately.   The document is in Polish concerning the decision taken, and I don't understand it. I am from Cameroon. My limited understanding from what was explained in English at the time was that the asylum status I requested was denied me. I only realised later that I asked the wrong authorities (border guards instead of immigration officers).  This was exactly one year and three months ago now. Do I still have access to any Schengen country?
Prove $\phi^n = \phi F_n + \text{(another Fibonacci number)}$ using mathematical induction. Where can the last FSTrim be seen as successful or not? (log files) Where are the NetworkManager logs? A previous poster on the regular forums (  ) said /var/log/daemon.log, but I don't seem to have such a file. Do I need to enable logging? When editing a post and using the image uploader, any unused link references are completely removed.  For example, this post has three image references, only one of which is used ([3]) in the body of the post:        After uploading a fourth image, references [1] and [2] are completely removed (and the remaining references are renumbered to become [1] and [2]):        I sometimes write link references before using them in the body of the post and sometimes remove images temporarily before reinserting them elsewhere in the post so this is inconvenient.  (Note: this also applies for the iOS app, having the same behavior) How does the Performance Index work? In one of Dota2's recent patches, Valve has added a new feature called "Performance Index" visible in your own in-game profile.  It is not clear how it works. Is there any information available, what "performance" it monitors?  Does it rely on K/D, K/D/A, Gold per minutes, Experience per minute, or all of them? My Mac is getting really slow, what should I do? From all the hard drives I have bought, they never seem to be as large as the advertised size; from 320 GB down to 290 GB, from 500 GB down to 450 GB, etc. Is there a technical reason for this? Is $\operatorname{lcm}(a,\gcd(b,c))=\gcd(\operatorname{lcm}(a,b),\operatorname{lcm}(a,c))$ What are the differences between Generics in C# and Java... and Templates in C++? C# 4.0 optional out/ref arguments How do I create an Ubuntu live USB using a Mac? I'd like to create an Ubuntu live USB stick on a Mac to use to install Ubuntu on another machine. How do I accomplish this? How to prove $\gcd(a^2, b^2) = (\gcd(a, b))^2$?  My attempt:  Let $\gcd(a, b) = d$.  Then $d|a$ and $d|b$ then $d^2|a^2$ and $d^2|b^2$. i.e $d^2$ divides $a^2 ~~\&amp;~~ b^2$. Basically the question is how to get from this:   foo_id   foo_name 1        A 1        B 2        C   to this:   foo_id   foo_name 1        A B 2        C change caption in list of tables I would like to change the caption in the List of Tables in a way it is different from the caption in the corresponding table. How can I do that? Does there exist a command to do that? How to create a function to sum the required multiple column I have a scenario where i want to sum the multiple column   The data in the file is :  ID|NAME|SAL|COST|PER|TAG  1|A|10|10|20|10|  1|B|10|15|20|10|  1|C|10|17|25|80|  1|D|115|110|20|100|  1|E|10|10|10|10|   i want sum of COLUMN - SAL | COST | PER | TAG   one i did with simple command but how to do by creating function  awk '{FS="|"}{s+=$3}END{print s}' file.txt   The function should be parameterised so that when i pass column name it should calculate sum for that column   The sum column's may differ. their may be requirement like only two column sum needed then it should take the two column names and process the sum for that There is a badge named Electorate which is going to be awarded on "Voted on 600 questions and 25% or more of total votes are on questions". Can somebody explain this to me?  Voted on 600 Question and 25% are on Question? is this  means   Voted on 600 Posts and 25% are on Question  Can't SO place some easy text or Definitions for average users? How do I protect Python code from being read by users? Okami is now reborn in High Definition for PS3. The graphics are obviously better, sharper and yet preserves the gist of the original game, however I can swear some of the texts have changed as well.  My PS2 console is no longer available to me so I can't test it myself, but does anyone know whether there are any changes to the game (aside from graphics) or not? Is there a way of setting culture for a whole application? All current threads and new threads? Is there a way of setting culture for a whole application? All current threads and new threads?  We have the name of the culture stored in a database, and when our application starts, we do   CultureInfo ci = new CultureInfo(theCultureString); Thread.CurrentThread.CurrentCulture = ci; Thread.CurrentThread.CurrentUICulture = ci;   But, of course, this gets "lost" when we want to do something in a new thread. Is there a way of setting that CurrentCulture and CurrentUICulture for the whole application? So that new threads also gets that culture? Or is it some event fired whenever a new thread is created that I can hook up to? Error when using apt-get update
