Starting from ArcGIS JS 4.x, under some special conditions, the MapView will have a blue border when the MapView is focus, who genius get this geneless idea? To get rid of this stupid box, style the following: .esri-view-surface--inset-outline::after {        outline: none !important;     padding: 0px !important; } So when this stupid design will come out? When ever your HTML got the following conditions, that stupid box will be shown when MapView is on focus: body {     margin: 0; }  #mapDiv {     width: 100% } ... The most weird API ever encountered

Esri still don't have a clue on how to modify a graphic in GraphicsLayer directly at version 4.8. You still need to clone the graphic, remove the existing one, and add the new one to realize the modification. Ref: https://developers.arcgis.com/javascript/latest/guide/functionality-matrix/index.html#graphicslayer Stone age API.

QEMU is a quick and clean solution for emulation. However, when compare to its alternatives like Virtualbox, it requires much more attention on its settings and tweak in order to get things work. The followings are some nice resources to make our life easier with that tool: QEMU setting

Starting from ArcGIS JS 4.6, the map server URL should not have any query parameters. Any query parameters exists in the map server URL will be removed. To handle this issues, you can override the urlUtils.removeQueryParameters() as below require(["esri/core/urlUtils" ], function(urlUtils) {    urlUtils.removeQueryParameters = function(a){       return a;    }; }); But somehow that's a bad trick. A better way is to use the TileLayer._set()  to get rid of the parameters stripping action when setting the URL. i.e. TileLayer._set('url', 'map_server_url')

For servers without CORS enabled. We can use proxy mechanism to access the services. This is done by modifying the proxy.ashx . You can also add any parameters before sending the request to the actual server. More references could be found at: https://developers.arcgis.com/javascript/latest/guide/proxies/index.html

The 'hosts' file in Windows allows user to add hostname to IP entries. When you modify the entries in hosts, the file explorer might not reflect the changes immediately. This is because the mapping is already cached in the Workstation service. Consider the following situation, you may hosts file with the following entry: 192.168.1.100   my_nas Then you can use \\my_nas\share in the file explorer to view content in \\192.168.1.100\share. Next, you try to modify the entry as following: 192.168.1.101   my_nas While the command ping my_nas tells you my_nas is now 192.168.1.101, but the file explorer cached the entry, hence \\my_nas\share still points to the old IP (i.e. 192.168.1.100). To clear this cache, apart from rebooting the machine, user can consider to restart the "Workstation" service instead.

To use LineDashedMaterial in three.js: var geometry = new THREE.Geometry(); geometry.vertices.push(new THREE.Vector3(590058.52, 231354.16, 766.42)); geometry.vertices.push(new THREE.Vector3(589941.68, 231476.67, 736.52)); geometry.vertices.push(new THREE.Vector3(589781.32, 231491.91, 757.73)); geometry.vertices.push(new THREE.Vector3(589711.88, 231445.56, 768.16)); geometry.vertices.push(new THREE.Vector3(589702.04, 231336.49, 772.91)); geometry.computeLineDistances(); let material = new THREE.LineDashedMaterial( {     color: 0xff0000,     linewidth: 1,     scale: 1,     dashSize: 5,     gapSize: 3, } ); let line = new THREE.Line(geometry, material); scene.add(line); Note:  You need to call geometry.computeLineDistances() to make the dash work computeLineDistances( ) only works with Geometry (Not work with BufferGeometry) The linewidth has no effect in Windows, it is always equals 1
