问题 Suddenly I can't add an RDS to my EB environment, not sure why. Here's the full error message: Unable to retrieve RDS configuration options. Configuration validation exception: Invalid option value: 'db.t1.micro' (Namespace: 'aws:rds:dbinstance', OptionName: 'DBInstanceClass'): DBInstanceClass db.t1.micro not supported for mysql db I am not sure if this is due to the default AMI that I am using or something else. Note that I didn't choose to launch t1.micro RDS instance. Seems like eb is

问题 I'm making a React app and trying to use Auth0 to authenticate. After trying to log in, it returns this: XMLHttpRequest cannot load https://my-domain.auth0.com/usernamepassword/login. Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Credentials' header in the response is '' which must be 'true' when the request's credentials mode is 'include'. Origin 'http://localhost:3000' is therefore not allowed access. The credentials mode of requests

问题 I've implemented a C++ Exception and throw this exception on errors without catching it. In linux I do see the exception text ("what") on console and the application exists. This is my expected behaviour. On windows (compiled with Visual C++ 2015) however a popup window opens and states a generic error. I do not see the exception message on console or anywhere else. Is it possible to log thrown/uncaught exceptions to console/stdout (or stderr) on Windows, too? Thank you 回答1: Throwing an

问题 I'm playing with building a vscode extension, using the TreeDataProvider API. I have a list of things showing, each TreeItem a composed label string, all works fine. What I am missing is a way of reacting to click events on any of the items. VSCode selects the item when you click on it, but I'd like to listen to that event, get the item in question etc... It's not obvious to me from the docs. In general, customizing the TreeItem is severely lacking, e.g. being able to colorize the label or

问题 bool bRet=LogonUser(strUserName, L"", strPassword, LOGON32_LOGON_TYPE_NEW_CREDENTIALS, LOGON32_PROVIDER_WINNT50, &phToken) bRet always returns true even if I enter a wrong password when there is no domain. Is there any work around like if I enter a valid password it returns true and false for a wrong password when there is no domain. 回答1: I assume that by LOGON32_LOGON_TYPE_NEW_CREDENTIALS you actually mean LOGON32_LOGON_NEW_CREDENTIALS . In which case the behaviour is exactly as would be

问题 The Gmail and Calendar APIs return a nextPageToken value in the response from the users.messages.list and events.list endpoints when pagination is required. If the value of the nextPageToken is provided in the next request to these endpoints, the next page of results is returned. My question : How long are these nextPageToken s persisted behind the Gmail and Calendar APIs? Context : I am building an abstraction on top of both the Gmail and Calendar APIs to return a list of Activities, and

问题 Is it possible to define as private the aggregate initialization for an aggregate class? I would like that the class can only be aggregate-initialized by its own static private members. Example: struct Size { const unsigned int width; const unsigned int height; static const Size big; static const Size small; private: Size( ) = default; // something to declare the aggregare initialization as private }; const Size Size::big = { 480, 240 }; const Size Size::small = { 210, 170 }; 来源： https:/

问题 Is there possibility to override publicPath in react-scripts for dev env. I use symfony and I include react app inside twig so I had to change assets to serve from http://localhost:3000/static/js/bundle.js - this works fine but I have problem with static files because they are rendered in browser as '/static/media/logo.813ua.png' and my current url is http://localhost:8000 What I did is I run yarn eject and modify in webpack.config.dev.js: var publicPath = 'http://localhost:3000/' and

问题 I have several dataframes with identical shape/types, but slightly different numeric values. I can easily produce a new dataframe with the mean of all input dataframes via: df = pd.concat([input_dataframes]) df = df.groupby(df.index).mean() I want to do the same with harmonic mean (probably the scipy.stats.hmean function). I have attempted to do this using: .groupby(df.index).apply(scipy.stats.hmean) But this alters the structure of the dataframe. Is there a better way to do this, or do I
