should a verb after the phrase "a series of" be singular or plural?   A series of incidents has taken place since the accident. A series of incidents have taken place since the accident.
Formally, is it correct to write:     A number of questions has been asked here.   or:     A number of questions have been asked here.   As a non-native speaker of English, I would prefer the former: the subject seems to be "number", therefore the verb ought to be singular, I'd say. However, the latter seems more common, and therefore I believe that my gut feeling is just plain wrong — but I would really like to have a definite answer.  Moreover, is it the same for "a myriad of", "a plethora of", and so on?
I am trying to animate a change in backgroundColor using jQuery on mouseover.  I have checked some example and I seem to have it right, it works with other properties like fontSize, but with backgroundColor I get and "Invalid Property" js error. The element I am working with is a div.  $(".usercontent").mouseover(function() {     $(this).animate({ backgroundColor: "olive" }, "slow"); });   Any ideas? Visiting Greece with back-to-back Schengen visas (One from Germany, other from Italy) I have a Schengen Visa issued by Germany, which expire on 11th Jan 2014, and I can remain in the zone till 11th Jan 23.59 PM. I have already visited Germany in the past with this visa, so I can travel whenever in Schengen zone directly from my country (Turkey).  I have a second Schengen Visa issued by Italy, which START on 12th Jan 2014, such that I can remain in Schengen zone from 12th Jan 00.00 AM onwards (I'm putting times to clarify which dates are inclusive).  I would like to travel to Greece with this visa: Entering the country on 6th January, and leaving the country on 19th January.  Is this allowed? Or do I have to leave the country first, and then re-enter through Italy? How to print variables without spaces between values I want to construct a complex power series with the radius of convergence $R=1$ that diverges in:  1) $k$ points on the circle $\{|z|=1\}$.  2) countable number of points on the circle  I have already crafted series that converges on the whole circle and diverges on the whole circle.  Can anybody help with the problem?  Update: I have googled a series $\sum{\frac{z^{kn}}{kn}}$ that is an answer for 1). Though I still need help for the countable case. Standard packages for compact SMT crystals There is an old and bog standard form factor for SMT crystals - HC49/US. The problem is that HC49/US takes a lot of real estate on the board.  It's 12mm long.  Another problem with crystals and oscillators in general is that they often become long lead time items.  [This is my experience.]  There are lots of small form factor crystals from various manufacturers.  But, at a glance, it seems that there is no standardization of form factor.  It’s nice when packages are standardized.  It alleviates the long lead time problem.  Crystals from manufacturer B may be used, if crystals from manufacturer A are out of stock.  Are there standard form factors for compact SMT crystals?  Update  Armed with the insights from Gribo and Gustavo, I did a more focused survey.  Found that 12MHz in 3.2x2.5mm package are produced by: Abracon, Citizen, Epson, Fox, ECS, TCS, NDK.  To be included in this list, the part had to be in stock at DigiKey.  It turns out that 3.2x2.5mm package is common across many manufacturers. For f continuous on $[0,1]$, show that there exist points $\alpha_k$ such that $\sum \limits_{k=1}^n \frac{1}{f'(\alpha_k)} = n $ WordPress and Git Workflow I know this question has been asked a thousand times, but I'm really trying to work out how to get the best out of Git when working with WordPress.  I've scoured the web and read dozens of articles, all that seem to cover the topic briefly. Here's a few of the most notable one's I've read recently.        Currently, my workflow looks like this.   Install WordPress locally Develop Theme Export WordPress Databases from local server Import WordPress Database to remote server Upload WordPress files and theme via FTP Client makes changes Download WordPress files and theme via FTP and export WordPress Databases from remote server Replace files locally Make development changes Re-upload via FTP, export and import database to remote server   I realise Git can streamline this process. It seems the best way to do this is to have a .gitignore file that ignores certain directories that don't need to be tracked, as well as having both a local and remote wp-config.php file.  But how do you handle the databases? Clients will usually make changes (posts/pages/plugins). Do I still need to export from the remote database and import back on my local server?  Can someone suggest the best workflow for me here? And walk me through the steps.  Also, I'd probably like to use Bitbucket as private repos with them are free, unlike GitHub.  Any help would be appreciated.  Thanks in advance! Why sometimes evidence is said to be too complex to compute and other times is negelected cause it is fixed? How to prevent unification when animating in photoshop? I am trying to create an animated gif where text drops down and smashes into the background and cracks it. Whenever I try and transform it though, the transformation is applied to all frames. How do I prevent this? I'm using Adobe Photoshop CS6 (64-bit) How to truncate a file in C? How can I make schematic of this board? I think the title says it all. Let's say you're mastering a game without the benefit of miniatures, maps, or any kind of physical representation of the environment. How would you keep track of details like line-of-sight, ranged attack viability, and all the other small nuances which go with creating a "believable-enough" environment in which your PCs live and thrive?  (I admit that @LoganMacRae, who is my own DM, is an inspiration for this question. He does this with panache, and in my one-off, I feel like I have some mighty big shoes to fill!) Why don't the Ubuntu repositories have the latest versions of software? Why are packages in the official Ubuntu repositories older than the latest (upstream) versions from Debian Sid, PPAs, the authors, etc.? What is $\sum_{n=1}^{\infty} \frac{n}{2^{\sqrt{n}}}$? I read that     A typical stream cipher encrypts plaintext one byte at a time, although a stream cipher may be designed to operate on one bit at a time or on units larger than a byte at a time.   (Source: , William Stallings.)  A block cipher encrypts one block at a time. The block may be of size one byte or more or less. That means we can also encrypt a block of one byte by help of a stream cipher as a stream.  So, what exactly is the difference between a stream cipher and a block cipher? How do I set the default program? How do I set the default program that I use?  I have tried to open System Info → Default Program → change my program, but it won't work,  Any idea? Or should I use Terminal?   I want to replace the default movie player with VLC media player, because the current movie player is useless to me. Or "Why is Ant-Man the last movie of Phase 2, rather than Avengers 2?"  The Marvel Cinematic Universe is the series of movies involving characters from Marvel comics and produced by Marvel Studio/Disney Studio. The series of movies is decomposed into phases, that are different steps in the studios' production plan.   Phase 1, entitled Avengers Assembled, is composed of all movies from Iron Man (2008) to The Avengers (2012). This phase relates the origins of each Avenger and how these mighty superheroes came to fight as a team.   The narrative purpose of Phase 2 is less clear to me. At first, I thought it was about Thanos' story arc but Thanos doesn't seem to appear in Ant-Man, the last movie of the Phase 2. Actually, Thanos will most likely be the main antagonist of Infinity War, which is a part of Phase 3.   Therefore, what story arc will be concluded at the end of Ant-Man? I believe it can be answered before the movie is released, as the purpose of Phase 1 was clear before the release of The Avengers. Marvel Studio may also have commented about the organization of the movies. In other words, what narrative elements unify the movie of Phase 2? Does a card that affects 'each' creature affect creatures that enter the battlefield after it resolves? Is there a max array length limit in C++? Is there a max length for an array in C++?  Is it a C++ limit or does it depend on my machine? Is it tweakable? Does it depend on the type the array is made of?  Can I break that limit somehow or do I have to search for a better way of storing information? And what should be the simplest way?  What I have to do is storing long long int on an array, I'm working in a Linux environment. My question is: what do I have to do if I need to store an array of N long long integers with N > 10 digits?  I need this because I'm writing some cryptographic algorithm (as for example the p-Pollard) for school, and hit this wall of integers and length of arrays representation. Why is this sentence correct?     She suggested that he go to the cinema.   I would definitely use goes instead of go.
