Is it okay to say      "a big news"   for example,     "I am telling you a big news"   or is it wrong? I heard a non-native English speaker say that.  The word "news" is mystery to me. It has a plural form, but it's singular non-countable. I have no idea how to use it properly.
This is a good news.    This is good news.    Which one is correct? Clarify the difference
Linking search box to dataset column in Carto? The search box in a published map of CartoDB isn't linked to the dataset which is shown in the CartoDB map. How can I link the search box to a certain column of a dataset? Careers: create PDF is not handling properly the sections Writing and Reading Scenario #1: no items in the section Writing, a few items in Reading   click on create pdf in the PDF you get your readings under the title "Writing" (should be "Reading")   Scenario #2: one item in the section Writing, a few items in Reading   click on create pdf in the PDF you get:   your readings under the title "Writing" (should be "Reading"), as in scenario #1 there are no writings (there should be one)    Hope it to be clear. Let me know in case it isn't.  Thank you! Can I take clear night sky photographs with my smartphone? is it possible to take clear night sky shots with stars/ planets visible from Redmi Note 4? what settings do I use? when I try to take it just comes black, unless on full moon day with HDR, though stars like Orion's belt won't get captured. Would using a telescope make celestial objects much clear to capture? How to enable root login again after changing password? I had enabled root login before and tried to change its password using this . But after successfully changing the password and locking it via sudo passwd -dl root. I cannot login back to SSH, it says Access is denied.  I have two users on my machine. root and admin, admin does not have su permission. When I try to use sudo on admin user, it says that admin is not in the sudoers file. That is why i need my su user back. I'm trying to identify a novel about an alien race coming to Earth. They are rabbit-like.    I thought it was Niven or Pournell but I cannot remember the title.  It was Quotzal or something like that. Motivation for Kolmogorov distance between distributions There are many ways to measure how similar two probability distributions are.  Among methods which are popular (in different circles) are:   the Kolmogorov distance: the sup-distance between the distribution functions; the Kantorovich-Rubinstein distance: the maximum difference between the expectations w.r.t. the two distributions of functions with Lipschitz constant $1$, which also turns out to be the $L^1$ distance between the distribution functions; the bounded-Lipschitz distance: like the K-R distance but the functions are also required to have absolute value at most $1$.   These have different advantages and disadvantages.  Only convergence in the sense of 3. actually corresponds precisely to convergence in distribution; convergence in the sense of 1. or 2. is slightly stronger in general.  (In particular, if $X_n=\frac{1}{n}$ with probability $1$, then $X_n$ converges to $0$ in distribution, but not in the Kolmogorov distance. However, if the limit distribution is continuous then this pathology doesn't occur.)   From the perspective of elementary probability or measure theory, 1. is very natural because it compares the probabilities of being in some set. A more sophisticated probabilistic perspective, on the other hand, tends to focus more on expectations than probabilities. Also, from the perspective of functional analysis, distances like 2. or 3. based on duality with some function space are very appealing, because there is a large set of mathematical tools for working with such things.  However, my impression (correct me if I'm wrong!) is that in statistics, the Kolmogorov distance is the usually preferred way of measuring similarity of distributions.  I can guess one reason: if one of the distributions is discrete with finite support -- in particular, if it is the distribution of some real-world data -- then the Kolmogorov distance to a model distribution is easy to compute.  (The K-R distance would be slightly harder to compute, and the B-L distance would probably be impossible in practical terms.)  So my question (finally) is, are there other reasons, either practical or theoretical, to favor the Kolmogorov distance (or some other distance) for statistical purposes? How to pass argument to script which is input to bash Who were the hooded people in The Rise of Skywalker? Near the end of Star Wars Episode IX: The Rise of Skywalker there are several hooded figures that are shown chanting stuff (in Sith?) and just hanging out with Palpatine. Who were these people? Why is SQL Server losing a millisecond? I have a table structured like this:  CREATE TABLE [TESTTABLE] (     [ID] [int] IDENTITY(1,1) NOT NULL,     [DateField] [datetime] NULL,     [StringField] [varchar](50),     [IntField] [int] NULL,     [BitField] [bit] NULL )   I execute the following code:  BEGIN     INSERT INTO TESTTABLE (IntField, BitField, StringField, DateField)     VALUES ('1', 1, 'hello', {ts '2009-04-03 15:41:27.378'});       SELECT SCOPE_IDENTITY()   END   And then   select * from testtable with (NOLOCK)   and my result shows:  2009-04-03 15:41:27.*377*   for the DateField column.  Any ideas why I seem to be losing a millisecond?? Python __str__ and lists Make file in linux readonly How to ensure only a single instance of my application runs? Does Python have a ternary conditional operator? If Python does not have a ternary conditional operator, is it possible to simulate one using other language constructs? What exactly is a hat?  I have seen a lot of people arguing the significance of hats and the limited edition hats. I know the hats are sort of linked to the Winterbash stuff, but what exactly is a hat, what does it do, how do I get one?  Is there a full list of hats? Why do we think of light as a wave? I've read that light travels in a straight line and has a wavelength of 400nm to 700nm. But I don't understand why does it have a wavelength and what creates its wavelength? I agree with the concept of sound which also has wavelength, thus called sound waves which are created by the vibrational movement in air. I'm not aware of calling light a wave. Does the light vibrate too? If so, then how? Is there a way to access an iteration-counter in Java's for-each loop? Is there a way in Java's for-each loop  for(String s : stringArray) {   doSomethingWith(s); }   to find out how often the loop has already been processed?  Aside from using the old and well-known for(int i=0; i &lt; boundary; i++) - loop, is the construct  int i = 0; for(String s : stringArray) {   doSomethingWith(s);   i++; }   the only way to have such a counter available in a for-each loop? What is the concept of erasure in generics in Java? whether it be vs whether it is I brought the sentences from the speech about conversation tips.     They don’t just want to know about news and the weather.   They want to know about you.   So what are three things that you have going on right now, that you can talk about.   Whether it be school, whether it be a personal relationship, whether it be a hobby that you’re involved with.   My questions:     What is the difference in nuance between 'whether it is' and 'whether it be'?   Before posting this question, I googled, and some websites say 'whether it be' is subjunctive. I don't get why it is called 'subjunctive'. Because from what I know about subjunctive, it's supposed to be past of be verb.    If I say 'whether it should be' or whether it would be', is the meaning same? Work done in adiabatic process Does measurement, quantum in particular, always increase the total entropy?
