Is it possible to run commands from spotlight? I run commands in terminal a lot and i'm wondering if it is possible to run the commands from spotlight. For example in spotlight  would like to run the command(because i have a lot of network issues):   ping google.com   And then spotlight to load terminal and execute the command instead of having to load terminal because it takes so long to load. So is this possible? Having problems with listings and UTF-8. Can it be fixed? I'm having some problems with listings and UTF-8 in my document. Maybe someone can help me?

Whenever I am traveling on foot, imperial ships will fly by and drop down troops for me to fight. In a normal situation, this is no big deal and I will fight or flee to continue with my travels.  However this will also occur when I am doing a quest that requires me to locate and pick up items. This is an inconvenience as I cannot pick up items while in combat and I have to kill them before I can continue.  Is there a way I can "hide" and allow the ships to by pass my location? Stopping all automatic updates Windows 10 I'm asked to show that $a^{61} \equiv a\pmod{1001}$ for every $a \in \mathbb{N}$. I've tried to tackle this using Fermat's Little Theorem and Euler's Theorem, but I can't even get started. My main problem seems to be the "for every $a \in \mathbb{N}$" part, because if it restricted $\gcd(a, 1001) = 1$ I would be able to factor out 1001 and try to show that it's factors divide $a^{61} - a$. I'm kinda lost here. Any help is appreciated. What (if any) countries are either open to or have set definitive plans to allow international tourism? Tasks in custom Environment I need to wrap a tasks environment inside a custom \NewEnviron.

I am pretty sure that a comma goes after the name, but lately I have seen several people (academics) write      Hello, John,       It was fun to see ...   with a comma after the Hello.  I am wondering when a comma there is appropriate.    I see this question  but I am wondering about the situation where you have a comma after the name also. Draw power from a portable mobile charger to power circuits Missing argument 2 for wpdb::prepare() Issue I'm having to update a WP installation for a community organisations from version 2.9.1 to the current 3.9.1.   The installation has a couple of custom built plugins that aren't documented.  I've just performed the WP version update and now I see a warning (Missing argument 2 for wpdb::prepare()) on every page that relates to the following line in the code of one of these custom built plugin:  $rows = $wpdb-&gt;get_results($wpdb-&gt;prepare("SELECT id, name FROM ".$table_name));   From what I've read online, this is due to a change in the coding, that requires 2 values to be sent to wpdb::prepare(), but I've no idea how the line of code given above, needs to be changed.  If someone could help me out, I'd really appreciate it. Media keys not working for iTunes (pause/play, skip buttons) Special Relativity - Regarding the Simultaneity of Events During the Train Paradox Sort order in Windows Explorer The behaviour described below occurs on Windows-7 systems and on Windows XP. We operate in a dual-language environment - English and Hebrew.  When in Windows Explorer we sort files by name, the order in which they are listed is not what we would expect. Here is a list of file names as sorted by Windows Explorer (all of the files have a .pdf suffix):   1G110033H-PP 19C050G-PP-ORB 19C050H-PPRM 19C100H-PPRM 19C-MBPS-PP 19C-MBPS-PP-1 29AAC050-PP 29AAC100-PP 29AAC100-PPUL   29B004064-PP 101AC050-PP 101AC100-PP 101B100-PPE 1091003G-PPFSUL 10108033G-PPSA 10125033H-PPM     It looks to me that first the items are sorted according to the position of the first alphabetic character in the name, and then, within those groups, they are sorted in "normal" alpha-numeric order.  That is, all the files with an alpha character in the first position are on top of the list, followed by those with the first alpha character in the second position, followed by those with the first alpha character in the third position, and so on.  An alternate way of looking at this is that, in a file name composed of numbers and letters, the sort treats the first group of numbers in the name as the major sort node, with the rest of the name being the secondary sort node.
