tilde

This question already has an answer here: What does the “~” (tilde/squiggle/twiddle) CSS selector mean? 5 answers I want to know what does (~) mean in css. #img1:hover ~ #img2 { opacity: 0; } In visual studio, i get 'unexpected character sequence' error when i use this symbol. what is the actual meaning of this in CSS. what does it do? MarcinJuraszek http://www.w3.org/TR/selectors/ 8.3.2. General sibling combinator The general sibling combinator is made of the "tilde" (U+007E, ~) character that separates two sequences of simple selectors. The elements represented by the two sequences share the

I'm a web application development noob. I have a function that opens a file and reads it. Unfortunately, the directory structures between the test and production servers differ. I was told to "use a path relative to ~". I haven't been able to find any resources on the '~', though! How do I use the tilde character in the context of paths? EDIT: This is in Python. I fixed the problem, using os.path.expanduser('~/path/in/home/area') . it is your $HOME var in UNIX, which usually is /home/username . "Your home" meaning the home of the user who's executing a command like cd ~/MyDocuments/ is cd

I was looking at this example that uses map . Here it is: mtcars %>% split(.$cyl) %>% # from base R map(~ lm(mpg ~ wt, data = .)) What is the meaning of the first tilde in map(~ lm... ? That is, how does R interpret the first tilde? (I understand that the second tilde indicates a function...) . Another way of asking is, why doesn't the following work? mtcars %>% split(.$cyl) %>% # from base R map(lm(mpg ~ wt, data = .)) As per the map help documentation , map needs a function but it also accepts a formula, character vector, numeric vector, or list, the latter of which are converted to

I was reading through some JMockit examples and found this code: final List<OrderItem> actualItems = new ArrayList<~>(); What does the tilde in the generic identifier mean? I know it's the unary bitwise NOT operator, but I don't see an operand here. Also, I tried compiling it and got an error. Am I just missing something? openCage It is just a shorthand for "same as in declaration". Some IDEs, e.g. IntelliJ use this too. The files on disk do not have this notation, which is only a compaction in the IDE GUI. If there wasn't a tilde, I'd say, the code was already Java 7. Java 7 allows the

I'm trying to get my head around the use of the tilde operator, and associated functions. My 1st question is why does I() need to be used to specify arithmetic operators? For example, these 2 plots generate different results (the former having a straight line, and the latter the expected curve) x <- c(1:100) y <- seq(0.1,10,0.1) plot(y~x^3) plot(y~I(x^3)) further, both of the following plots also generate the expected result plot(x^3, y) plot(I(x^3), y) My second question is, perhaps the examples I've been using are too simple, but I don't understand where ~ should actually be used. The issue

what is the use of ~ tilde in URL? I am using cPanel, and have link including tilde, why is tilde there? When we buy server space but do not have dns or don't want to use it for development purposes,we use the like http://serverip/~foldername . vkrams Actually tilde '~' represents home directory. When you place tilde in url, It will access from home directory T.E.D. Well, a webserver is free to use any character after the leading URI part for whatever purpose it wants. That being said, the use of ~ generally hearkens back to the early days of the web, when just about every web server ran on
