I am Saket Patel, an Indian national, studying in France. I have French long stay visa and residence permit (social security). I need to travel to UK for a meeting/conference and I do not know if I need a separate visa for that purpose.  Kindly help me out and let me know if I can travel there with these documents or do I need to apply for visa separately?
I'm an Egyptian citizen, who holds Schengen visa and stay permit in Italy. Can I go to UK for some days with my stay permit and Schengen visa?
How to never "allow this device to access photos and videos"? What's the origin of referring to female superior officers as "sir"? It is well established in Star Trek: The Next Generation that female superior officers are normally referred to as sir.  This is applied to Dr. Crusher, Counselor Troi, Cmdr. Shelby, Maj. Kira, Lt. Dax, and numerous admirals.   This obviously fits in well with the egalitarian ideals of Star Trek. This convention is made explicit in &quot;Thine Own Self&quot;:  DATA: Counsellor, have you been promoted in my absence? TROI: That's right. Which means from now on you can call me sir. DATA: Yes, sir.  In Addition, the first episode of Star Trek: Voyager, &quot;Caretaker&quot; contains this dialog:  KIM: Thank you, sir. JANEWAY: Mister Kim, at ease before you sprain something. Ensign, despite Starfleet protocol, I don't like being addressed as sir. KIM: I'm sorry, ma'am. JANEWAY: Ma'am is acceptable in a crunch, but I prefer Captain. We're getting ready to leave. Let me show you to the bridge.  which again establishes that sir is the norm, although Capt. Janeway doesn't prefer it. Did this usage of the honorific sir start with ST: TNG or does it predate TNG in either sci-fi or the real world?  Related: How would you go about proving that $$\gcd \left(\frac{a}{\gcd (a,b)},\frac{b}{\gcd (a,b)}\right)=1$$  for any two integers $a$ and $b$?  Intuitively it is true because when you divide $a$ and $b$ by $\gcd(a,b)$ you cancel out any common factors between them resulting in them becoming coprime. However, how would you prove this rigorously and mathematically? How do I escape a single quote in SQL Server? I have float raster and now I want to convert it to vector. How is it possible with the Python GDAL library?  I have tried with gdal_polygonize.py of GDAL utilities on the command line and it worked excellently. But this utility is based on GDALPolygonize() of C++ library and I want to C++ method GDALFPolygonize() to be used instead, which manipulates float raster data as far as I know. The set that only contains itself I'm seeing an odd character like a very flat U, where there should be a space, with the listings package. See example below.

AFAIK, you never need to specify the protocol in an onclick:  onclick="javascript:myFunction()" Bad  onclick="myFunction()" Good  Today I noticed in  on Google Anallytics that they are using it:  &lt;a href="http://www.example.com" onClick="javascript: pageTracker._trackPageview('/outgoing/example.com');"&gt;   Is this example just plain wrong, or is there ever a reason to specify javascript: in anything other than a href? How to do binary calculation？ Why should I install hardware drivers if my computer is working fine? I've just installed Windows 7 on my PC.  I went online to look for drivers. For , Foxconn offers LAN drivers, on-board audio drivers, and chipset drivers. And for , Nvidia offers a graphics card driver, obviously.  But then I stopped and wondered... what benefit would I gain from installing them?   The LAN cable is plugged in and I'm online; no problems there.  The on-board audio is working fine.  A quick Google tells me that a chipset is responsible for moving data around my motherboard – which seems to be happening OK!  And my graphics look perfect.    So why should I install the drivers? What would they give me, other than badly designed "management" interfaces, and pointless "notifications" whenever I plug in an audio jack?  If there are different considerations for each of the components – chipset, audio, LAN, and graphics (and any others you think I should be aware of) – please break it down in your answer.     Update: I've had a couple of answers already, saying that I'll get better stability, bugfixes, etc.   Can I slightly expand my question... Can I get all these same benefits if I install the drivers via Windows Update? And if I do this, would I avoid having to install the vendor-specific UIs, which I find so annoying? Make two vector points move together (Sketch or Illustrator) How do I run an application with arguments from the command line without losing the terminal? I use dwm as a window manager on Ubuntu, I like tiled windows and I like them as few as possible. I sometimes need to run an application (let's say it's the pdf viewer mupdf in x11) from the terminal, the application will be launched in a new window but the terminal from which I launched becomes this prompt-less console for that application to log whatever.  I use dmenu to launch applications, but sometimes an application needs arguments (file names) to start. I use uxrvt within x11 managed by dwm. Render looks darker than Look Dev mode I have been texture painting in look dev mode. But when i try to render it, everything looks very dark.

I really like the look of my scene in Look Dev mode, how can i achieve the same look when my scene is rendered too?
