dynamic server time

由 吃可爱长大的小学妹 提交于 2019-12-11 02:37:26
问题 As I understand there is no way I can get dynamic server time in IE with settimeout() in script.. I found this example: function timeExam(){ $.ajax({ url : "inc/clock.php", success : function (data) { $("#clock_time").html(data); } }); var func = function() { timeExam(); } setTimeout(func, 1000); } <body onload="timeExam();"> bla bla bla </body> Maybe it is possible to make it work? If not, could you please suggest me a dynamic clock with server time that works in all browsers?! I tried a

How can I produce a table of transition types in R?

由 喜夏-厌秋 提交于 2019-12-11 02:36:29
问题 I have some data which has a number of different id's in it and a list of their states at different times (t1, t2, t3 etc) and I'd like to generate a table that gives information about the different types of state change that happen, so something that would look like this for the sample data (copied below). x y z x 0 2 0 y 1 2 1 z 1 0 2 Which would show, for example, that x changed to y twice and y changed to x once. Does anyone know how I might be able to do this in R? SAMPLE DATA: id <- c(

Use python to dynamically create bash aliases

由 佐手、 提交于 2019-12-11 02:34:17
问题 I'm attempting to use python to dynamically create bash aliases (like, for example, aliases to log in to a set of servers). I'd love to be able to do something like this: from subprocess import call SERVERS = [ ("example", "user@example.com"), #more servers in list ] for server in SERVERS: call('alias %s="ssh %s"' % (server[0], server[1]), shell=True) The problem is that subprocess launches the jobs in a separate shell session, so the program runs fine, but does nothing to the shell session I

Rust dynamic cast trait object between different taits

由 老子叫甜甜 提交于 2019-12-11 02:09:14
问题 I was wondering if it is possible to cast a trait object to another trait object. I tried the following code: trait TraitA { fn say_hello(&self) { self.say_hello_from_a(); } fn say_hello_from_a(&self); } trait TraitB { fn say_hello(&self) { self.say_hello_from_b(); } fn say_hello_from_b(&self); } struct MyType {} impl TraitA for MyType { fn say_hello_from_a(&self) { println!("Hello from A"); } } impl TraitB for MyType { fn say_hello_from_b(&self) { println!("Hello from B"); } } fn main() {

Create Dynamic Proxies objects

由 混江龙づ霸主 提交于 2019-12-11 02:05:48
问题 Is there a way to create WCF proxy objects on the fly without using codedom? By on the fly I mean during runtime. So lets say I have a smart client application that is accessing a WCF service. The Data Contract for the WCF service is changed while the client is running. I want to dynamically create a new proxy object that reflects the changed data contract. 回答1: You should read this article: WCF the Manual Way… the Right Way And look into using the ChannelFactory class. You are going to have

Polynomy function with changing number of parameters

由 不羁的心 提交于 2019-12-11 01:59:26
问题 is it possible (in Python) to define a polynomial type of function that has changing amount of parameters? Number of parameters should change according to number of data series that I have in my input file. Currently I have something like this: def y(x, a0, x2, x3, x4): y = a0 + a1*x + a2*x**2 + a3*x**3 return y I could of course set parameters of higher order to zero by extra parameter but would there be some better way. 回答1: You can loop over the arguments and evaluate the polynomial using
