问题 I'm using jwilder/nginx-proxy with separate docker-compose.yaml . It looks like this: proxy: image: jwilder/nginx-proxy restart: always volumes: - /var/run/docker.sock:/tmp/docker.sock:ro - ./nginx/conf.d/proxy.conf:/etc/nginx/conf.d/proxy.conf:ro - /Users/marcin/Docker/local_share/certificates:/etc/nginx/certs:ro ports: - "80:80" - "443:443" container_name: proxy I'm using it for quite a long time and it's working fine when my project docker-compose.yaml looks like this: web: build: /Users

问题 I have several dataframes in a list in R. There are entries in each of those DF I would like to summarise. Im trying to get into lapply so that would be my preferred way (though if theres a better solution I would be happy to know it and why). My Sample data: df1 <- data.frame(Count = c(1,2,3), ID = c("A","A","C")) df2 <- data.frame(Count = c(1,1,2), ID = c("C","B","C")) dfList <- list(df1,df2) > head(dfList) [[1]] Count ID 1 1 A 2 2 A 3 3 C [[2]] Count ID 1 1 C 2 1 B 3 2 C I tried to

问题 I've had trouble with keeping my users logged in, so I did some testing and I noticed that the function viaRemember always returns false . This is my login controller function with all the irrelevant code stripped off: public function postSignin(Request $request, AppMailer $mailer) { $this->validate($request, [ 'email' => 'required', 'password' => 'required', ]); $username = $request->get('email'); $password = $request->get('password'); $field = filter_var($username,FILTER_VALIDATE_EMAIL)?

问题 I am interested in creating a 3D visualization of network packets. A few years ago these things sold for tens of thousands of dollars, but now I think that I can hack one together in a few hours using an open source 3D kit. I've looked around and have found two kids that look good --- one is Panda3D and the other is CrystalSpace. My requirements are: Fast to learn Able to run from python or C++ Able to work with 50,000 polygons. (I want to represent each packet as a little brick in 3D space.)

问题 I started learning OpenCV today and I wrote a short code to upload (I don't know, if it's the right term) a random image: 1 It works fine, and I can open the image, but what I get is a big window and I can't see the full image unless I scroll it: 2 So, I'd like to know a way that I could see the whole image pretty and fine in a shorter window. 回答1: You can resize the image keeping the aspect ratio same and display it. #Display image def display(img, frameName="OpenCV Image"): h, w = img.shape

问题 I'm having some trouble getting a working Camel Spring-Boot unit test written, that tests a simple SNMP route. Here is what I have so far: SnmpRoute.kt open class SnmpRoute(private val snmpProperties: SnmpProperties, private val repository: IPduEventRepository) : RouteBuilder() { @Throws(Exception::class) override fun configure() { logger.debug("Initialising with properties [{}]", snmpProperties) from("snmp:0.0.0.0:1161?protocol=udp&type=TRAP") .process { exchange -> // do stuff } .bean

问题 I currently have a python file that I have to run for different excel files on a daily basis. The steps are : Open .py file change directory of excel file run python file write to .xlsx This takes in a excel file as a pandas dataframe does some manipulation and other things and spits out an excel file. The problem is that I have to change the directory each time manually in the code. I would rather build a nice GUI for me to pick the source file that I want to manipulate, pick the output

问题 I'm trying to implement a program that returns the number of existing partitions of an integer n as part of an assignment. I wrote the code below, but it returns the wrong number (Partitions n returns the result of Partitions n-1). I don't get why this happens. I've tried many things and still don't know how to fix it, can anyone please help me? [edited code out to avoid plagiarism from my colleagues :p] m stands for the biggest number allowed in a partition, so partition(4,4) would be 5 = 4,

问题 From C++ Primer 5th edition By Stanley Lippman et al(19.5): A nested class can have the same kinds of members as a nonnested class. Just like any other class, a nested class controls access to its own members using access specifiers. The enclosing class has no special access to the members of a nested class, and the nested class has no special access to members of its enclosing class . Is there any truth to the bolded part? I could find no mention of the nested class being restricted access
