Given the following gun unordered list, how is a machine remove from the list of machines?
let gun = new Gun();
let machineId = 'cool-machine';
let location = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
let machines = gun.get('machines');
let machine = gun.get('machine/' + machineId);
machine.put({machineId, location});
Use gun/unset:
include gun/unset either in node or browser. It is in the lib folder.
machines.unset(machine);

I followed the tutorials from the Forge Data Visualization extension documentation: https://forge.autodesk.com/en/docs/dataviz/v1/developers_guide/quickstart/ on a Revit file. I used the generateMasterViews option to translate the model and I can see the Rooms on the viewer, however I have problems coloring the surfaces of the floors: it seems that the ModelStructureInfo has no rooms.
The result of the ModelStructureInfo on the viewer.model is:
t {model: d, rooms: null}
Here is my code, I added the ITA localized versions of Rooms as 3rd parameter ("Locali"):
const dataVizExtn = await this.viewer.loadExtension("Autodesk.DataVisualization");
// Model Structure Info
let viewerDocument = this.viewer.model.getDocumentNode().getDocument();
const aecModelData = await viewerDocument.downloadAecModelData();
let levelsExt;
if (aecModelData) {
levelsExt = await viewer.loadExtension("Autodesk.AEC.LevelsExtension", {
doNotCreateUI: true
});
}
// get FloorInfo
const floorData = levelsExt.floorSelector.floorData;
const floor = floorData[2];
levelsExt.floorSelector.selectFloor(floor.index, true);
const model = this.viewer.model;
const structureInfo = new Autodesk.DataVisualization.Core.ModelStructureInfo(model);
let levelRoomsMap = await structureInfo.getLevelRoomsMap();
let rooms = levelRoomsMap.getRoomsOnLevel("2 - P2", false);
// Generates `SurfaceShadingData` after assigning each device to a room (Rooms--> Locali).
const shadingData = await structureInfo.generateSurfaceShadingData(devices, undefined, "Locali");
// Use the resulting shading data to generate heatmap from.
await dataVizExtn.setupSurfaceShading(model, shadingData, {
type: "PlanarHeatmap",
placePosition: "min",
usingSlicing: true,
});
// Register a few color stops for sensor values in range [0.0, 1.0]
const sensorType = "Temperature";
const sensorColors = [0x0000ff, 0x00ff00, 0xffff00, 0xff0000];
dataVizExtn.registerSurfaceShadingColors(sensorType, sensorColors);
// Function that provides a [0,1] value for the planar heatmap
function getSensorValue(surfaceShadingPoint, sensorType, pointData) {
const { x, y } = pointData;
const sensorValue = computeSensorValue(x, y);
return clamp(sensorValue, 0.0, 1.0);
}
const sensorType = "Temperature";
dataVizExtn.renderSurfaceShading(floor.name, sensorType, getSensorValue);
How can I solve this issue? Is there something else to do when using a different localization?
Here is a snapshot of what I get from the console:
Which viewer version you're using? There was an issue causing ModelStructureInfo cannot produce the correct LevelRoomsMap, but it gets fixed now. Please use v7.43.0 and try again. Here is the snapshot of my test:
BTW, if you see t {model: d, rooms: null} while constructing the ModelStructureInfo, it's alright, since the room data will be produced after you called ModelStructureInfo#getLevelRoomsMap or ModelStructureInfo#getRoomList.
I have a cytoscape graph with these extensions:
Automove
Expand-Collapse
In my graph I have normal nodes with smaller nodes beside them (here in yellow). These smaller nodes are set with automove to move along with their linked node.
This happens with this function:
private addCircle(nodeId: string, circleText: string): void {
var parentNode = this.graph.getElementById(nodeId)
if (parentNode.data('isCircle') || parentNode.data('circleId')) return
var px = parentNode.position('x') + 10
var py = parentNode.position('y') - 10
var circleId = (this.graph.nodes().size() + 1).toString()
parentNode.data('circleId', circleId)
this.graph
.add({
group: 'nodes',
data: { id: circleId, name: circleText },
position: { x: px, y: py },
classes: 'XorGroup_' + circleText,
})
.unselectify()
.ungrabify()
this.graph.automove({
nodesMatching: this.graph.getElementById(circleId),
reposition: 'drag',
dragWith: parentNode,
})
}
If I move the "parent" its works totally fine, but if I use the collapse function of the "Expand-Collapse" extension, the nodes are seperated from their "parent" and get placed in the upper left corner.
This collapse event is used on totally different nodes.
I tried to use this function:
cy.nodes().on("expandcollapse.aftercollapse", function(event) { var node = this; ... })
Unfortunatelly it fires before the layout is calculated by the "Expand-Collapse" extension.
Does anybody have an idea how to manage, that the smaller nodes are ALWAYS on the same relative position to their "parent"?
To start off, here's my main bot.js code (Sorry if it seems like code spaghetti. I'm not the best with javascript):
const fs = require('fs');
const Discord = require('discord.js');

I'm creating a bot that should be pretty simple:
The bot is a RankBot (at least that's what i dubbed it as), which is supposed to track the amount of wins in battles (since this is for a discord about a fighting game) using a special role that manually increments those wins with a command, then being able to pull up a leaderboard embed showing the people with the most wins. I'm testing it in a discord separate from the one it's for with a friend, and it seemingly worked until we commanded the bot to open the leaderboard. Nothing was shown. We thought it was strange, since it worked before when only one user was in the database, and I went to the PowerShell Command Line to see if there was an error message, and this showed up.
C:\Users\USER\Documents\OF_RankBot\bot.js:89
battleleaderboard.addField(client.users.get(data.user).tag || client.members.get(data.user).tag, `${data.points} Win(s)`);
^
TypeError: Cannot read property 'tag' of undefined
We were confused by what happened, so I removed the tag part of the command and used it again. The embed showed up this time, but it looked like this.
I assumed that what went wrong was that since they both had the same number of wins listed, the part of the bl command that sorts the users was confused. I then went and used bl_add_point on me and tried again. The near exact same embed was shown.
My guess as to what went wrong was that I messed up at some point when setting up the bl_add_point command, but I'm not sure how to fix the issue.
This isn't part of the main problem, but I can't seem to get bl_delete working either. No errors are shown when I use it. In fact, seemingly nothing happens. I'm not sure if these issues are connected, but I really only need the main issue fixed.
Thanks in advance.
edit: I found out partially what happened with the bl_delete issue, which was I simply put the prefix into the case when the prefix was already defined. Now when I put in the command, the PowerShell responds with:
C:\Users\USER\Documents\OF_RankBot\bot.js:72
client.removeScore.run(`${member.guild.id}-${member.id}`)
^
TypeError: Cannot read property 'id' of undefined
I want to get my coordinates in every 1 minute even app close or background. But what ever I did, I couldnt do that. I used background-task but it works minimum in every 7m30s so it doesn't help me.
I used 'react-native-geolocation-service' like this :
this.watchID = Geolocation.watchPosition((lastPosition) => {
this.setState({ initialPosition: lastPosition });
Latitude = lastPosition.coords.latitude;
Longitude = lastPosition.coords.longitude;
var lat = parseFloat(lastPosition.coords.latitude);
var lng = parseFloat(lastPosition.coords.longitude);
console.log("lat2 :",lat);
console.log("lng2 :",lng);
},
(error) => alert(JSON.stringify(error)),
{enableHighAccuracy: true, maximumAge: 0, distanceFilter: 1, useSignificantChanges: true});
to get coordinates when I move in every 1 meter but it keeps continue to give coordinates and never stop. And also it doesnt work when app closed.
Expo SDK v32.0.0 release includes initial support for background location.
I'm new to Stackoverflow and this will be my first question. My HTML5 player works fine on Internet Explorer but doesn't work on google chrome. I'm using a PlayReady stream which is encrypted with CENC. How can I let this work on chrome? I don't have access to the servers, they're run by third parties.
Thanks
Technically it is possible to support Widevine while you're stream is PlayReady. This is possible since you use CENC. Since you don't have access to the servers like you mentioned you can use a technique called PSSH Forging. It basically replaces the pieces to make chrome think it's Widevine, since it's CENC the CDM will decrypt the video and the stream will play.
For the sake of ease i'm going to assume you use DASH.
We have here a PSSH Box:
const widevinePSSH = '0000005c7073736800000000edef8ba979d64acea3c827dcd51d21ed0000003c080112101c773709e5ab359cbed9512bc27755fa1a087573702d63656e63221848486333436557724e5a792b32564572776e64562b673d3d2a003200';
You need to replace 1c773709e5ab359cbed9512bc27755fa with your KID.
And then at the part where you insert you'r segment in the SourceBuffer (before appendSegment) you can do the following:
let segment = args[0];
segment = new Uint8Array(segment);
const newPssh = widevinePSSH.replace('1c773709e5ab359cbed9512bc27755fa', psshKid);
const subArray = new Uint8Array(DRMUtils.stringToArrayBuffer('70737368'));
let index = 0;
const found = subArray.every((item) => {
const masterIndex = segment.indexOf(item, index);
if (~masterIndex) {
index = masterIndex;
return true;
}
});
if (found) {
return originalSourceBufferAppendBuffer.apply(this, [].slice.call(args));
}
segment = DRMUtils.uInt8ArrayToHex(segment);
// Inject the forged signal
// 70737368 = pssh
segment = segment.substr(0, segment.lastIndexOf('70737368') - 8) + newPssh + segment.substr(segment.lastIndexOf('70737368') - 8);
// Fix the MOOV atom length
// 6d6f6f76 = moov
const header = segment.substr(0, segment.indexOf('6d6f6f76') - 8);
const payload = segment.substr(segment.indexOf('6d6f6f76') - 8);
const newLength = Math.floor(payload.length / 2);
segment = header + DRMUtils.intToHex(newLength, 8) + payload.substr(8);
segment = decode(segment).b;
Sadly i can only share bits and pieces but this is roughly what you should do to get it working.
