Craft thy own Bayeux Tapestry Slay mischievous beasts Rule the kingdom. Two German students originally wrote the Historic Tale Construction Kit, with Flash. Sadly, their work isn't available anymore, only remembered. This new application is a tribute, but also an attempt to revive the old medieval meme, with code and availability that won't get lost.

QUESTION
I'm trying to do a chloropeth map following this guide: https://www.r-graph-gallery.com/327-chloropleth-map-from-geojson-with-ggplot2.html
I mixed a bit of the tutorial with this answer(Chloropleth map with geojson and ggplot2), since I wasn't getting the result I expected. The cities were being filled with the same color, and it seemed as R wasn't understanding the data as numeric, and filled every city that had at least 1 user with the default color. (tried using as.numeric, didnt work either)
I downloaded "users by city" data from my website from Google Analytics using
...ANSWER
Answered 2020-Jan-28 at 22:09It looks like you have a couple relatively large values, while most are small. This causes 'skewing' of your color scale in a way that looks less interesting. Instead of graphing number of users, consider mapping based on a quantile .
Here is an implementation of grouping into quantiles using cut2()
from Hmisc
. In this case, values are cut into 5 groups.
QUESTION
I'm trying to use CometD with websocket transport in my webapp, but the handshake with such transport fails with error "Unknown Bayeux Transport", and CometD always fallback to long-polling.
I'm using
- Java 8
- CometD 3.1.8 and Jetty 9.4.14.v20181114 libraries
- Tomcat 8.5 as container
Here is the web.xml
...ANSWER
Answered 2019-May-23 at 14:31In general, CometD recommends to deploy in Jetty and to use the latest release (at this time 4.0.4).
Your web.xml
has incorrect values for the transports
init-param
.
JettyWebSocketTransport
is a CometD transport that uses Jetty-specific API in its implementation; as such, it only works when your application is deployed in Jetty.
I recommend that you remove the transports
init-param
and let CometD pick the proper defaults, which will work in both Jetty and Tomcat.
For the record, the default WebSocket transport is org.cometd.websocket.server.WebSocketTransport
which is based on the standard JSR 356 APIs that are implemented by both Jetty and Tomcat.
Your client is correct, although there also you may want to use the standard WebSocket transport, org.cometd.websocket.client.WebSocketTransport
.
I tried the command to generate a project from the archetypes and works fine for me.
Perhaps you have a hint in the error: URI does not specify a valid host name: http:/cometd.org
- see how there is only 1 slash, not the required 2 slashes.
In summary:
- Move to CometD 4.0.x
- Move to Jetty if you can
- Remove the
transports
configuration and use the defaults. - Re-run the archetypes with the right URL:
https://cometd.org
.
QUESTION
I am working on a Spring-MVC project where I am using Spring-security for authentication and authorization. Along with that, I am using Cometd library for sending messages over websockets. After receiving the message inside a Listener, when I try to get the currently authenticated user, it's always null.
How can I make sure that each request in Cometd atleast contains the JSESSIONID which is required by Spring-security for identifying?
Or is there some setting in Spring-security which can make this possible.
As I looked up, there are many users facing this issue, but no definitive answer or code which is helpful.
Test code :
...ANSWER
Answered 2019-Feb-01 at 12:36Solution for: - CometD 4.0.2 - Spring 4.3.9.RELEASE - Spring Security 4.1.0.RELEASE
In my project we faced similar problem while switching from "long pooling" to "websocket" connection. For clarification - one difference - we were using "user context" only during "handshake".
With usage of "long pooling" Cookie with JSESSIONID was interpreted correctly by Spring and we were working in "user context". After switching to "websocket" it looked like "user context" was lost just before running message receiving code.
We could not find proper solution - following code is in my opinion just a hack. But it worked for us.
QUESTION
I'm trying to determine the URL for SalesForce as it relates to setting up a Kafka Provider. I'm using Bayeux
client that needs a URL to SalesForce for connection:
ANSWER
Answered 2018-Sep-03 at 07:17It seems you are using this Kafka library, which has nothing to do with Salesforce, but you give it a string of your Kafka broker addresses, as shown in the examples there.
Note: That library doesn't look actively maintained and Kafka is not an http protocol so putting http://server:9092
doesn't make sense...
You might want to checkout confluent-kafka-dotnet instead.

I have to subscribe to cometD Salesforce channel and hence building cometD client in python. I am using the below python library.
https://github.com/dkmadigan/python-bayeux-client
And below is the handshake response I am getting
...ANSWER
Answered 2018-May-30 at 14:36I believe that the authorization key is incorrect. It is not your password that is expected but an OAuth access token or session id that you receive after you log into salesforce. See the different OAuth flows, if you are testing you can use the username password flow.
The following method u can use to get the session id when needed

QUESTION
My application is subscribed to some Broadcast Bayeux channel. It also listen's to meta channels to receive any advice in case of any connection failure via /meta/connect. Now my question is do I need to restart my Bayeux client i.e first disconnect() and try handshake() again Or only handshake() call is enough to get the connection back when I get reconnect=handshake as advice ??
Please comment for any further info on this.
This is how I set up the longpolling connection for bayeux client
...ANSWER
Answered 2018-Feb-21 at 17:16You don't need to do anything.
The information carried by the advice
field is handled by the implementation, so your application (or any application) should not perform any action based on the information of the advice
field.
For applications, the advice
field is just informative.
