What would be the quickest way to construct a Python binding to a C or C++ library?  (I am using Windows if this matters.) What's the difference between adjusting highlights and shadows in the basic panel and in the tone curve in the Develop Module of Lightroom? I wanted to reduce some highlights in a photo and found that there were two possible ways of doing so: one from the basic panel and another from the tone curve. when I reduce the highlights in one pane the value on the other is unchanged. Are both of them the same thing? Which would be better? In my , I provided the following, problematic,  wording (especially bold italic), and I need help to better understand this issue so I can fix my answer:1          The thing is the books. (Reduced form of Sentence 2.a)         Fundamentally, Sentence 2.a (the so-called "correct" answer), is grammatically defective. Recall there is another grammatical rule: the subject and subject's complement should match in number.    A clarification is needed here. I am not suggesting here, in this EL&amp;U question, that there is any such singular grammatical rule as indicated in the quote above.  The quote continues as follows:     The reduced sentence makes the disagreement between the subject's and complement's plurality obvious. What is one to do? Language is linear and we know "The thing is X" is better than "The thing are X", so we go with the former, which is the subject-verb agreement rule. But what is "the books" then? It must be thought of as a collective noun, even if it doesn't look or feel like one. Forcing something to be a collective noun is related to the idea of notional agreement.   Others noted that grammatically defective is too strongly worded.  There is no such "grammatical rule" for subject/complement agreement.  Please help me understand/improve upon my line of thought here.  I'm stating that Sentence 2.1 presents a fundamental "conflict" or "error" (however one might define error) at some level (morphological, syntax, grammatical, semantic):     The thing is the books.  (Or, "The thing is the objects.")   Based on the "obvious" morphosyntactic plurality conflict, the above sentence feels so wrong that I think many native speakers would think it "simply" grammatically incorrect. However, @F.E. gives counter examples:     And here are some more grammatical examples, where the number of subject and predicative complement don't agree: "They were a problem to us all", "That so-called work of art is simply four pieces of driftwood glued together" (CGEL, page 254-5). As CGEL says: "What is required is semantic compatibility, not syntactic agreement . . .". There are more examples on page 512: "The only thing we need now is some new curtains", "The major asset of the team is its world-class opening bowlers", "Our neighbors are a nuisance", "This gadget is five different tools in one".   I think all the examples given above can be explained as notional agreement.    Question 1: If we explain this phenomena in terms of notional vs syntactic agreement, where does "grammatically correct/incorrect" fit in?  Question 2: Can a simple sentence such as "The thing is the objects." be grammatically incorrect while more complex sentences such as "The thing is four pieces of driftwood glued together." be grammatically correct?  (The answer, in my mind, must be no; this is my conundrum.)  Question 3: Would it be better to say that Sentence 2.a has a low level of (linguistic) ?   Question 4: How about a low level of  and that it's semantically difficult to be (linguistically) ?    Question 5: Do we simply draw a hard line and say "The thing is the objects." is 100% grammatically correct?  I didn't particularly like this option based on intuitive notions of "grammatically correct".    1. Please help me and be kind; I'm trying to improve my understanding. I'm looking for cool, objective advice on how to look at this.  I numbered my questions so they can be easily referenced, if desired.  My preference is the final answer would sufficiently answer all the questions, but of course that can be done explicitly or implicitly. Convert HTML entities to Unicode and vice versa The tutorial I read is based on 2.79. So I'm not sure if it's still the same name in 2.8. But I can't find anything providing similar functionalities. ASP.NET MVC 3 localization with DisplayAttribute and custom resource provider MacBook is displaying the message "no hardware installed" when I click on Wi-Fi I have a MacBook Pro 2009 running MacOS El Capitan. Recently the Wi-Fi has stopped working.   When I click on the Wi-Fi icon it displays the message "No hardware installed", but Ethernet still works.   Is there any way of fixing this by using a Wi-Fi dongle or something of the sort, if so do I need a specific dongle and how do I install it?

Looking at         it says "36% unknown". No user by the name of 'unknown' appears in the  ()  What madness is this? Who is this 'unknown' you speak of? Is it true that the order of $ab$ is always equal to the order of $ba$? As far as I know, those are the only two.  They should be pronounced Soogher and Soor, shouldn't they?  I looked them up on Dictionary.com, and their etymologies reveal no trace of an SH, except where the listing for sugar had:     Middle English sugre, sucre (noun) &lt; Middle French sucre  &lt; Medieval Latin succārum  &lt; Italian zucchero  &lt; Arabic sukkar;  obscurely akin to Persian shakar, Greek sákcharon   I see an obscure kinship to shakar, but the word morphed so many times since then that the SH disappeared pretty much completely.  And sure is even worse, with no sign of SH:     Middle English sur ( e ) &lt; Middle French sur, Old French seur  &lt; Latin sēcūrus   Why are these the only two like this? I need this date format in a visualforce page: "December 14, 2013". I can't seem to find the format options for visualforce. I read that it's the same as the java messageformat class options, but I cannot find a list for that either.  A little help would be much appreciated Case assignment rule is always executed in the test class Proving $R-S$ contains a prime ideal when $S$ is a multiplicative set I'm mainly trying to prove that      If $0\not \in S\subseteq R$ is a multiplicative subset of a   commutative ring $R$ with identity. Then $R-S$ contains a prime ideal.   Now, by using Zorn's lemma, one can show that $R-S$ contains a maximal ideal I. In fact, I is a prime ideal as well, so we need to show this.To do that, I assumed the opposite, i.e $\exists a,b \in R$ s.t $ab\in I$, but $a,b \not \in I$. Then looked each case. However, I stuck when $a,b \in R-[S\cup I]$. The following is what I've done for this case;  Proof:  In this case, our assumptions are $a,b\in R-[S\cup I]$ and $I + (a) = J$, where $J$ is an ideal in $R$ and $J \cap S \not = \emptyset$.   These imply that; $S^{-1}(I + (a)) = S^{-1} J$, but since $J \cap S \not = \emptyset$, by a theorem that we proved in the class, $S^{-1} J = S^{-1}R$.Therefore, it must be true that $\exists (i\in I, r\in R, s_1,s \in S)$ s.t  $$\frac{i+ra}{s_1} =\frac{1}{s}$$ but this implies $\exists s_2 \in S$ s.t  $$ s_2(is + sra -1 s_1) = 0 \quad \Rightarrow \quad (s_1 s )i + (s_1 s r) a = (s_1 s )1,$$ ,so $$(b s_1 s )i + (s_1 s r) ab = (s_1 s )b.$$ Observe that by our assumption $ab\in I$, so $(s_1 s)b \in I$.  Now, at the point, I don't know how to proceed, so I would appreciate any help or hint because I stuck at this point for over a week now.  Edit  Thanks for the great answers; however, but I'm specifically interested in how to continue from the point where I stuck. What is the C# equivalent of NaN or IsNumeric? How to display Trash and Home folder icons? In a particular textbook, the work function of a metal (in the context of the photoelectric effect) is defined as:     the minimum amount of energy necessary to remove a free electron from the surface of the metal   This sounds similar to ionisation energy, which is:     the amount of energy required to remove an electron from an atom or molecule in the gaseous state   These two energies are generally different. For instance, Copper has a work function of about 4.7eV but has a higher ionisation energy of about 746kJ mol-1 or 7.7eV.  I've sort of figured it's because the work function deals with free electrons whilst ionisation is done with a valence electron still bound within the atom. Is the difference due to the energy required to overcome the attraction of the positive nucleus? I have a very strange behavior on an Android device (Nexus 7) when trying to access local network applications. Instead of getting the actual IP of the machine on LAN, the Android device gets the public IP, which means that Chrome, Firefox or any other browser simply shows the web page of the router.  I have an internal DNS server which handles the local networks. Doing ping from a PC works correctly:  $ ping s.pelicandd.com  PING pelicandd.com (192.168.1.15) 56(84) bytes of data. 64 bytes from front.pelicandd.com (192.168.1.15): icmp_seq=1 ttl=64 time=0.524 ms 64 bytes from front.pelicandd.com (192.168.1.15): icmp_seq=2 ttl=64 time=0.578 ms ^C   On an HTC One device (accessed with adb shell), it works well too:  shell@m7:/ $ ping s.pelicandd.com  PING pelicandd.com (192.168.1.15) 56(84) bytes of data. 64 bytes from front.pelicandd.com (192.168.1.15): icmp_seq=1 ttl=64 time=2.56 ms 64 bytes from front.pelicandd.com (192.168.1.15): icmp_seq=2 ttl=64 time=27.8 ms ^C   However, this is what I get when doing the same ping from Nexus 7:  shell@flo:/ $ ping s.pelicandd.com  PING pelicandd.com (90.78.26.42) 56(84) bytes of data. 64 bytes from LFbn-1-2441-42.w90-78.abo.wanadoo.fr (90.78.26.42): icmp_seq=1 ttl=64 time=2.56 ms 64 bytes from LFbn-1-2441-42.w90-78.abo.wanadoo.fr (90.78.26.42): icmp_seq=2 ttl=64 time=8.63 ms ^C   Instead of resolving to the internal IP, it resolves to the public one.  The network configuration is—except the IP address of the device—exactly the same on both devices: IP settings are set to Static, and DNS servers are the internal ones. Both Android devices are connected through Wi-Fi (unlike the PC). A major difference, however, is that Nexus 7 is using Android 6.0.1, while HTC One uses Android 5.0.2.  There is no nm-tool, dig or nslookup on Nexus 7. The device is not rooted.  The problem existed since I bought the device a few weeks ago, so it could hardly be the issue with DNS cache.  What can I do to further inspect this issue?
