问题 I would like to move down my entire data by a factor of two months. For example, if my data starts on Jan 01, i want to move the data in such a way that the data corresponds to March 01. Likewise, November data would become January data for the next year. Here is my sample code DF <- data.frame(seq(as.Date("2001-01-01"), to= as.Date("2003-12-31"), by="day"), A = runif(1095, 0,10), D = runif(1095,5,15)) colnames(DF) <- c("Date", "A", "B") I tried DF$Date <- DF$Date + 61 but this moved the

问题 Using VisaulVM, I'd like to obtain this as data, without image processing algorithms being applied... How can I do that? I think this won't come out of a snapshot. I am not sure how VisualVM and jVisualVM vary, the naming is sure confusing, but I'm running the Oracle supplied one ( Version 1.7.0_80 (Build 150109) ) Thanks! 回答1: You can use Tracer plugin with various probes. Tracer can export data in CSV, HTML or XML. 回答2: All this information is available through JMX. That's how VisualVM gets

问题 I keep reading documentation that gives parameters for kube-proxy, but does not explain how where these parameters are supposed to be used. I create my cluster using az aks create with the azure-cli program, then I get credentials and use kubectl. So far everything I've done has involved yaml for services and deployments and such, but I can't figure out where all this kube-proxy stuff fits into all of this. I've googled for days. I've opened question issues on github with AKS. I've asked on

问题 I want to filter the rows of a dataframe that contains values less than ,say 10. import numpy as np import pandas as pd from pprint import pprint df = pd.DataFrame(np.random.randint(0,100,size=(10, 4)), columns=list('ABCD')) df = df[df <10] gives, A B C D 0 5.0 NaN NaN NaN 1 NaN NaN NaN NaN 2 0.0 NaN 6.0 NaN 3 NaN NaN NaN NaN 4 NaN NaN NaN NaN 5 6.0 NaN NaN NaN 6 NaN NaN NaN NaN 7 NaN NaN NaN 7.0 8 NaN NaN NaN NaN 9 NaN NaN NaN NaN Expected: 0 5 57 87 95 2 0 80 6 82 5 6 33 74 75 7 71 44 60 7

问题 I have created a custom property dedicated to holding properties of the view that require invalidate() call for one of my projects: class InvalidatingProperty<T>(private var _value: T) { operator fun getValue(thisRef: View, property: KProperty<*>): T { return _value } operator fun setValue(thisRef: View, property: KProperty<*>, value: T) { _value = value thisRef.invalidate() } } In another project, I wanted to reuse some of my previous work, so i copied the views and their dependencies,

问题 I'm working on a C application that interacts with a mssql database running on Windows 2008 R2. I'm able to connect to the database and run specific queries, but when i use SQLBindParameter things fall apart. I found a post on stackoverflow that appears to be the same problem, but the solution doesnt appear to be the same (Problems getting SQLBindParameter to work in C++). According to C Data types SQL_C_CHAR is correct (https://msdn.microsoft.com/en-us/library/windows/desktop/ms714556(v=vs

问题 I want to use a background for my buttons. But when I use a png it slows down the app. Therefore I want to use a xml shape but I do not know how to make the corner cut (like on the picture). By now I have the following shape which is just a rectangle: <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"> <solid android:color="@color/blue_semi_transparent"/> <padding android:bottom="10dp" android:right="10dp" android:top="10dp" android:left=
