negation

问题 I realize the title is crazy, but it really is the best I could think of. If anyone has better suggestions please leave them in the comments and I'll edit. This question is a followup to the question asked here : Drools Constraint object other than P is found in collection For those who don't want to click, that post describes the solution to the situation in which you want to know if there is a fact of CustomType which has a member field containing a value other than P. The Solution to this

问题 Hi and thanks for looking! I'm searching for articles which contain certain strings with full text search, something like this: SELECT * FROM Articles_fts WHERE body MATCH 'monkey OR banana OR "hungry gorilla"'; My real search is much longer (22 terms) and probably not the smartest way of doing this but it's working so no problems there. What I need help with... Now I want to return the OPPOSITE of what this search returns. In other words I want all the articles that don't contain monkey,

问题 In my application I use several profiles to make certain beans eligible for autowiring. What I'm missing is the possibility to make a bean eligible for autowiring when a certain profile is NOT active. The best way of doing it that I thought about is like this: Let's suppose we have a list of all possible profiles, e.g. {A, B, C, D}. Profiles active for particular execution are {A, C}. What I do is I create artificial profiles for all possible profiles which are not active. In the example case

问题 I was wondering if anyone was familiar with any attempts at algorithmic sentence negation. For example, given a sentence like "This book is good" provide any number of alternative sentences meaning the opposite like "This book is not good" or even "This book is bad". Obviously, accomplishing this with a high degree of accuracy would probably be beyond the scope of current NLP, but I'm sure there has been some work on the subject. If anybody knows of any work, care to point me to some papers?

问题 I realize this is a simple question, but I am finding a hard time getting an answer due to the finnicky syntax requirements in bash. I have the following script: if ! [ [ -z "$1" ] || [ -z "$2" ] ]; then echo "both arguments are set!" fi I get the following output when I run it without arguments: ./test: line 3: [: -z: binary operator expected both arguments are set! I am not expecting any output - neither argument is set. What am I doing wrong? 回答1: The test shell builtin [ supports the

问题 I'm trying to negate the max-device-width media query (the reason for this is I don't won't both (max-device-width: X) and (min-device-width: X) to fire if the device has precisely that width). Unfortunately, the not (min-or-max-some-width: X) media queries never fire. Here's a small fiddle. I expect two yellow lines on the desktop and two red lines on mobile. What I get is only one yellow line on the desktop (the last one) and only one red line on mobile (the first one). What am I doing

问题 I want to select spans that are not the descendants of a specific class, let's call it "no". Here's my CSS: div:not(.no) span{background-color:#00f;} Here's the HTML <div> <span>yes 1</span> </div> <div class="no"> <span>no 1</span> </div> <div class="no"> <div> <span>no 2</span> </div> </div> Two questions: Why does my CSS apply to both yes 1 and no 2? Why does the whole thing break if I switch to a universal selector? *:not(.no) span{background-color:#00f;} Here's the code in JSFiddle: http

问题 I was asked to do a query in sql using double negation. The question itself is asking for all the "sigla" and "disciplina "where the semestre_id is 21 and has at least 1 attribute "resposta"=5 table query Now despite posting all this my question is mostly that I am not too sure if this is the way of doing a proper double negation in sql, since I am getting as an answer all the lines of the table which is wrong. Since I am having an hard time searching for examples online could anyone clarify

问题 Some language grammars use negations in their rules. For example, in the Dart specification the following rule is used: ~('\'|'"'|'$'|NEWLINE) Which means match anything that is not one of the rules inside the parenthesis. Now, I know in flex I can negate character rules (ex: [^ab] , but some of the rules I want to negate could be more complicated than a single character so I don't think I could use character rules for that. For example I may need to negate the sequence '"""' for multiline
