The dbus-daemon manual makes several references to "well-known" things. Examples:
On platforms other than Windows, unix-based transports (unix, systemd, launchd) are the default for both the well-known system bus and the well-known session bus
This is the default for the well-known system bus and for the well-known session bus.
Rules with the own or own_prefix attribute are checked when a connection attempts to own a well-known bus names.
I get the feeling "well-known" has a kind of legalistic meaning in the context of the manual but i cannot find any reference it.
The documentation for the pydbus library explains it as:
The bus name. This identifies which application you want to
communicate with. You’ll usually identify applications by a well-known
name, which is a dot-separated string starting with a reversed domain
name, such as org.freedesktop.NetworkManager or
com.example.WordProcessor.
you can see these listed if you busctl e.g:
$ busctl list

D-Bus has two ways of naming "buses" (connections): unique connection names and well-known bus names.
Speaking in networking terms, unique connection name is like an IP address while well-known bus name is like a DNS entry for that. The application requests/registers well-known bus name and clients can later use it to find the application.

I am trying to setup and connect to a Cassandra single node instance using docker and Golang and it is not working.
The closest information I could find to addressing connection issues between the golang gocql package and Cassandra is available here: Cassandra cqlsh - connection refused, however there are many different upvote answers with no clear indication of which is preferred. It is also a protected question (no "me toos"), so a lot of community members seem to be having trouble with this.
This problem should be slightly different, as it is using Docker and I have tried most (if not all of the solutions linked to above).

Admittedly, I am a little shaky on what listening addresses I should pass to Cassandra in the environment section, so I just passed 'home':
- CASSANDRA_RPC_ADDRESS=127.0.0.1
- CASSANDRA_BROADCAST_ADDRESS=127.0.0.1
- CASSANDRA_LISTEN_ADDRESS=127.0.0.1
If you try and pass 0.0.0.0 you get the following error:
cassandra00_1 | Exception (org.apache.cassandra.exceptions.ConfigurationException) encountered during startup: listen_address cannot be a wildcard address (0.0.0.0)!
cassandra00_1 | listen_address cannot be a wildcard address (0.0.0.0)!

Overall, however I think that I am getting the correct start up procedure for Cassandra (afaict) because my terminal outputs that Cassandra started up as normal and is listening on the appropriate ports:

In my golang code I have the following package that is being called (simplified to show relevant section):
package data
import(
"fmt"
"github.com/gocql/gocql"
)
func create_userinfo_table() {
<...>
fmt.Println("replicating table in cassandra")
cluster := gocql.NewCluster("localhost") //<---error here!
cluster.ProtoVersion = 4
<...>
}
Which results in the following error in my terminal:
app_1 | [21:52:38][WEBSERVER] : 2018/09/10
21:52:38 gocql: unable to dial control conn 127.0.0.1:

I have tried several variations on the connection address
cluster := gocql.NewCluster("localhost")
cluster := gocql.NewCluster("127.0.0.1")
cluster := gocql.NewCluster("127.0.0.1:9042")
cluster := gocql.NewCluster("127.0.0.1:9160")
These seemed likely candidates for example, but no luck.
Does anyone have any idea what I am doing wrong?
Use the service name cassandra00 for the hostname per the docker-compose documentation https://docs.docker.com/compose/compose-file/#links
Containers for the linked service are reachable at a hostname identical to the alias, or the service name if no alias was specified.
Leave the CASSANDRA_LISTEN_ADDRESS envvar unset (or pass auto) per https://docs.docker.com/samples/library/cassandra/
The default value is auto, which will set the listen_address option in cassandra.yaml to the IP address of the container as it starts. This default should work in most use cases.
Setting up JanusGraph i noticed the following in the console:
09:04:12,175 INFO ReflectiveConfigOptionLoader:173 - Loaded and initialized config classes: 10 OK out of 12 attempts in PT0.023S
09:04:12,230 INFO Reflections:224 - Reflections took 28 ms to scan 1 urls, producing 2 keys and 2 values

and then i see the following:
Exception in thread "main" java.lang.IllegalArgumentException: Could not instantiate implementation: org.janusgraph.diskstorage.es.ElasticSearchIndex
How do i stop using elasticsearch and switch to Solr?
My properties file is as follows:
index.search.backend=solr
index.search.directory=/path/to/directory/for/solr/index/something
index.search.index-name=something
index.search.solr.mode=http
index.search.solr.http-urls=http://127.0.0.1:8983/solr
storage.backend=cassandrathrift
storage.hostname=127.0.0.1
cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-time = 180000
cache.db-cache-size = 0.25
The answer to this basically the same as this one for Titan. JanusGraph was forked from Titan.
You are probably trying to connect to an existing graph that was previously configured to use Elasticsearch. By default, the keyspace is named janusgraph.
1) You could connect to a different keyspace by updating conf/janusgraph-cassandra.properties
gremlin.graph=org.janusgraph.core.JanusGraphFactory
storage.backend=cassandrathrift
storage.hostname=127.0.0.1
storage.cassandra.keyspace=mygraph
2) You could drop the existing keyspace. If you used bin/janusgraph.sh start from the quick start directions (which starts a single node Cassandra and a single node Elasticsearch),
bin/janusgraph.sh clean
Or if you have a standalone Cassandra installation:
$CASSANDRA_HOME/bin/cqlsh -e 'drop keyspace if exists janusgraph'
Then you would be able to connect with the default conf/janusgraph-cassandra.properties.
I am using sonar-runner-2.4 on sonarqube server 4.5.6 ( Windows 7-32 bit).

Is there anything that I am still missing in terms of configuration or anything in general?
Thanks in advance...
As per Issues Report Plugin documentation:
To get an HTML report, set the sonar.issuesReport.html.enable property to true
You can also enable this by default in the SonarQube General Settings ('Issues Report' section).
Im new to graph db and I'm totally lost since few days. Im trying to run rexster with titan db 0.5.4 with berkeleyje storage backend.
but I'm not sure if the rexster.xml configuration is correct.
if I follow the rexster docs I got in the doghouse empty db with no vertices or edges while actually there are. screenshot

From a fresh salt stack installation on server and client, the goal is to serve a file with a number inside:
SERVER
$vim /etc/salt/master
...
file_roots:
base:
- /srv/salt
...
$echo 1 > /srv/salt/tmp/salt.config.version
$cat /srv/salt/top.sls
base:
'*':
- tmpversion
$cat /srv/salt/tmpversion/init.sls
/tmp/salt.config.version:
file.managed:
- source: salt://tmp/salt.config.version
- user: root
- group: root
- mode: 644
CLIENT (minion)
$vim /etc/salt/minion
...
master: <masterhostnamehere>
...
I'm using salt '*' state.sls tmpversion to apply the configuration. I don't know how to get the changes applied automatically..
Salt doesn't do anything until you tell it to. So that means that you have to run the salt command on the cli when you want a state to be applied, or you can use Salt's internal scheduler or your system's cron to run the job regularly.
