I am using the module "Rhea" (https://www.npmjs.com/package/rhea) which has the typings for typescript in their own /typings folder (so /node_modules/rhea/typings) of the module instead of delivering a @types module I can install by NPM.

QUESTION
ANSWER
Answered 2020-Oct-22 at 09:30I think a lot of what you did, specifically around data wrangling, was not necessary, especially since you called d3.hierarchy()
and d3.cluster()
afterwards. I've replaced this with d3.stratify
(which deals with hierarchical data that is not yet in the right format).
I've also replaced d3.cluster
with d3.tree()
because it was unclear to me why you'd want to use d3.cluster
here. Your data has multiple parents, multiple roots and even floating nodes, and d3 is not meant to deal with that. My workaround has been to attach pseudonodes to every level, so as to make sure that there is only one node and that all nodes are at the right level at all times. To make sure the links were drawn correctly, I've written a custom getLinks
function, that can deal with multiple parents.
I've also written a custom link generator that draws the links somewhat in the way that you want them. d3 doesn't offer much of flexibility here, but you can use the source code for inspiration.
Edit
I've changed the logic to be more focused on which "partners" got a child, so both links to the same child are on the same level - like in your picture. I've also drawn the nodes based on how many partners they have, and have given every link an offset so the lines are more distinct.
I've sorted the nodes so that the real pro-creators are at the top (Zeus), which gives a more balanced and less crowded view.
QUESTION
I have bitbake a recipe in which I need to check for the availability of a remote server before downloading some packages from it. For that, I'd use ping as below:
...ANSWER
Answered 2020-Oct-07 at 07:31bitbake uses the safer set -e
by default: the script execution stops on first error.
You could disable this (with set +e
) but I suggest handling the single known-to-fail command specifically instead. There's a few ways you can do it, here's an example (this also fixes a bug in your code where you used the exit value of echo as your exit value):
QUESTION
enter image description herethis is the data structure of the table.
...ANSWER
Answered 2020-Sep-30 at 10:03You have a multiple problems in your statement:
- you have single quote character inside this string:
lname:'O'Reilly'
- this lead that it's thinking that line is continuing. You need to escape it correctly with either additional'
character:lname:'O''Reilly'
, or using$$
for string boundaries. - you're using incorrect quotes for strings in the map - you're using double instead of single
- you have incorrect data types for some fields, like,
reviewer_id
, etc. - you don't need to put column names into the double quotes - this is required only when you want to have case-sensitive names
The working query is following:
QUESTION
This is just a bit of a nonsense example but it perfectly describes my problem.
The following call of the object's function gives undefined
for bird
property:
ANSWER
Answered 2020-Jun-04 at 10:38In a regular function, this
is the object from which the function is called. If you call birds.func()
, then inside this function this === birds
. If the function is called just like func()
, then the context will be window
(undefined
in strict mode). In the callback function that you passed to map, this
is window
or undefined
. The arrow function works differently - it inherits this
from the context where it is declared.
Use () => {} for inherit this

QUESTION
From the ActiveMQ documentation (https://activemq.apache.org/consumer-priority), it seems that broker does support Consumer prioritization. I'm trying to use this feature using nodejs and rhea library. The problem is, that there is no clear documentation how to do it - I can't even find a place to see if I managed to change priority of a consumer. The dashboard (localhost:8161) does show priority of messages, but nothing is said about priority if consumers..
...ANSWER
Answered 2020-Apr-06 at 18:43An AMQP Receiver can set the priority of the internally created Consumer the broker creates by adding the same options as an Openwire client adds to the JMS destination. In this case it'd be done by adding the option along with the desired destination name to the address given by the Source when creating a receiver link.
QUESTION
I need to find my data that matches the particular type. Say, I have an array of objects in my DB, with each object having it's leadType : all
or leadType: blacklist
. Each object has a different kind of leadType
value associated with it.
I want to get the complete data that matches the particular leadType, like leadType: 'radar'
.
I tried using the following query but along with the documents it matches, it also returns the empty documents that do not matches the specified projection.
This is what I tried:
...ANSWER
Answered 2020-Apr-02 at 05:27If you want to match only the documents with leadType
equals to radar
you should specify this in the find condition.
QUESTION
I'm currently working on a macro enabled excel sheet, with multiple tabs (there are 9 tabs I would like to do this on, but for the purposes of the question I'll include only 2), and for each tab I would like to add a password prompt that matches what I specify in the code.
This is working ok, but my issue is that when two sheets are located next to each other on the actual worksheets tab, it will go through them both rather than hiding the first one until i input the correct password.
For example, on my sheet I have a tab named Cascada, followed by a tab named Cascada2. If I were to put a blank tab inbetween these two, then my code would work correctly. However when they are in sequence, it seems to go through the sequence of password prompts regardless of whether I input the correct string or not.
See code below, any advice would be appreciated.
Thanks.
