I hold both a British and Russian dual citizenship, holding two passports. I am soon going on a flight to Russia and am not sure what passport to enter in the Advanced Passenger Information section.  What passport do I enter?
I am a citizen of two different countries, and have two passports.  How should I use my passports when traveling?
Custom thumbnailers don’t work on Ubuntu 18.10 and 18.04 Recently I had a bunch of my own scripts for the thumbnails in Nautilus: , , office documents and so on.  Seems like either I’m doing something wrong (thumbnail generation behavior changed), or custom thumbnailes don’t work in latest GNOME at all, even my previous scripts, which worked smoothly on previous versions of Ubuntu.  I’ve done some research, tried to run a simple script (see below) and it didn’t work out.  My test thumbnailer in /usr/share/thumbnailers/z.thumbnailer:  [Thumbnailer Entry] Exec=/home/maximal/thumb.sh %s %i %u %o MimeType=image/webp;image/x-webp   Where /home/maximal/thumb.sh is:  #!/bin/bash echo $0 &gt;&gt; /home/maximal/thumb.log echo $1 &gt;&gt; /home/maximal/thumb.log echo $2 &gt;&gt; /home/maximal/thumb.log echo $3 &gt;&gt; /home/maximal/thumb.log echo $4 &gt;&gt; /home/maximal/thumb.log   Then, when I remove thumbnail cache rm -rf ~/.cache/thumbnails and restart Nautilus nautilus -q, my log file doesn’t contain anything and ~/.cache/thumbnails/fail/gnome-thumbnail-factory contains all the failed thumbs (looks like corrupted/empty PNGs):    So, apparently, Nautilus even didn’t try to execute my thumbnailer script. When I try to run thumb command itself, it works perfectly. For example convert through cwebp|dwebp package:  convert -thumbnail 256x256 file.webp png:file.webp.png   When I wrap this command to a thumbnailer, it looks like it wasn’t even requested to run by Nautilus.  [Thumbnailer Entry] Exec=convert -thumbnail %sx%s %i png:%o MimeType=image/webp;image/x-webp;   Exactly the same situation occurs with other my thumbnailers: audio waveforms, office documents, photoshop files and so on.

Python/Matplotlib - Is there a way to make a discontinuous axis? Evaluate the limit      $$ \lim_{n\rightarrow \infty}\left(\frac{n+1}{n}\right)^{n^2}\cdot \frac{1}{e^n} $$   My Attempt:  $$ \lim_{n\rightarrow \infty}\left(\frac{n+1}{n}\right)^{n^2}\cdot \frac{1}{e^n} = \lim_{n\rightarrow \infty}\left(1+\frac{1}{n}\right)^{n^2}\cdot \frac{1}{e^n} $$  How can I solve the problem from this point? Inertial forces and centre of mass Is inertial force always attached to the centre of mass of the object? Why? What rules cause this to happen?  See the  below of the leaned bike in a corner.    The force $m\frac{v^2}{r}$ pointing to the right is the centrifugal force (inertial force - because it's a rotating reference frame, therefore a non-inertial reference frame). It is attached to the centre of gravity of the bike.  I'm thinking that inertial force is attached to the centre of mass because of the fact that it should simply avoid creating a torque on the object. That's intuitive, but there must be a general rule that allows us to conclude that. For example:  "Last week, I found out that NASA stands for 'National Aeronautics and Space Administration.'"  or  "Last week, I found out that NASA stood for 'National Aeronautics and Space Administration.'" I wanted to take a sneak peek at Windows 7 so I thought of installing it. I have Windows Vista on my laptop which came pre-installed with it. I didn't want to mess with it.  So I created a partition (20 GB) in my USB external hard disk and tried to install Windows 7 on that partition. But when I booted from a Windows 7 DVD and selected the target partition on USB hard disk, it said it cannot be installed.  Is there any way to install Windows on an external USB hard disk?

In the , the key $k = (a, b)$ should have the following property, i.e. GCD of $a$ and the modulus should be 1:     $\gcd (a, m) = 1$, where $m$ is the set of possible moduli   My question is, why it is required that $a$ should have the above property? What is the significance of this? And why is $b$ excluded from this condition? When to use an object pronoun or a possessive adjective before a gerund Problem in installing Python 3.3 in Ubuntu 12.04 Predicator vs. Predicate BACKGROUND According to Oxford Dictionaries Online:   means &quot;(In systemic grammar) a verb phrase considered as a constituent of clause structure, along with subject, object, and adjunct.&quot;  means &quot;The part of a sentence or clause containing a verb and stating something about the subject (e.g. went home in John went home).&quot;  In the latter example of John went home, it seems, the predicate is went home whereas the predicator is went, home being an adjunct and thus not part of the predicator as defined. Now, I looked further in  to better understand the difference. The article recognizes two competing notions of the predicate in theories of grammar:  (1) Predicates in traditional grammar (e.g., went home in John went home) (2) Predicates in modern theories of syntax and grammar (e.g., went in John went home)  Which, according to the article, causes confusion as to what exactly the term predicate mean, and some grammarians came up with a new term &quot;predicator&quot; specifically for use (2), says the article. No problem thus far. What bothers me: The article in its explanation of (2) says, &quot;Other function words -- e.g. auxiliary verbs, certain prepositions, phrasal particles, etc. -- are viewed as part of the predicate.&quot; (Emphasis mine.) Now, remember this definition of the predicate, i.e., (2) above, corresponds to the new term &quot;predicator&quot;. I understand that auxiliary verbs are part of this definition of predicate, because an auxiliary verb can be part of a verb cluster. But can certain prepositions and phrasal particles also? The article has these example sentences (Words belonging to &quot;predicate&quot; (2) are boldfaced as in the article itself; My comments in parentheses.):  The butter is in the drawer. (preposition in being part of the predicate) You should give it up. (particle up being part of the predicate) Susan is pulling your leg. (I don't know why leg is marked as part of the predicate. Maybe a typo?)  QUESTION Except for the last one, which I suspect is a typo, I'd like to know whether the preposition in and the particle up belong to the predicate as presented in (2) and thus belong to the new term &quot;predicator&quot;. What is the difference between logistic regression and Fractional response regression? As far as I know, the difference between logistic model and fractional response model (frm) is that the dependent variable (Y) in which frm is [0,1], but logistic is {0, 1}. Further, frm uses the quasi-likelihood estimator to determine its parameters. Normally, we can use glm to obtain the logistic models by glm(y ~ x1+x2, data = dat, family = binomial(logit)). For frm, we change family = binomial(logit) to family = quasibinomial(logit). I noticed we can also use family = binomial(logit) to obtain frm's parameter since it gives the same estimated values.

A blinding light / blinding sunlight / a blinding sunlight "Mornings came and cast a blinding sunlight over everything, and he felt like nothing worthwhile could be accomplished."  For some reason, I feel like "a blinding light" is ok, but if its sunlight, then I should drop the "a" and write "cast blinding sunlight", but I'm not sure why I feel this way.   Can anyone offer some enlightenment?  edit - alternate phrasing, closer to being a literal translation: "Mornings came without warning, flooding the day with a strong sun, and he felt like nothing worthwhile could be accomplished."   I would still like an answer to the technical question of whether I should drop the "a", but would also appreciate knowing if anyone thinks option #2 is a better choice.
