WMS | warehouse management system base on Spring MVC | Object-Relational Mapping library

I made this codepen to experiment with OpenLayers and a WCS layer. I understand there is no WCS support but I do manage to display it using an Image layer and an ImageWMS source since WCS is exposed using the same API as WMS. My question is this : Why is it that whgen I perform an .updateParams({ RANGESUBSET: 'B1995' } for example does my map object does not create a proper request like the initialization request which displays the data for the first step?

I am having really weird issues with memory leak and I cannot find source after long hours of testing, debugging and trial/error attempts.

The source of memory leak is reloading object base on push from subject. On which part I load current database values and add it to SourceCache.

This part is getting the push, to initiate reload

I have a Pandas DataFrame for which I would like to calculate some weighted means, with respect to a group given by a column 'Class'.

I was having fun solving the riddles from the Pythonchallenge website

when I stumbled upon a weird behaviour:

With this input: *g fmnc wms bgblr rpylqjyrc gr zw fylb. rfyrq ufyr amknsrcpq ypc dmp. bmgle gr gl zw fylb gq glcddgagclr ylb rfyr'q ufw rfgq rcvr gq qm jmle. sqgle qrpgle.kyicrpylq() gq pcamkkclbcb. lmu ynnjw ml rfc spj.

We should be able to get the following output: *"i hope you didnt translate it by hand. thats what computers are for. doing it in by hand is inefficient and that's why this text is so long. using string.maketrans() is recommended. now apply on the url." *

Instead what we get when we decipher it with a simple ROT2 script is: i hope you didnt tr{nsl{te it |y h{nd0 th{ts wh{t computers {re for0 doing it in |y h{nd is inefficient {nd th{t)s why this text is so long0 using string0m{ketr{ns+ is recommended0 now {pply on the url0*

My ROT2 script I refer to is as follows:

First, I want to mention that I am very new to WebRTC, so any advice would be very helpful.

Currently I am using aiortc library to build my own WebRTC app. Here is what I am trying to do.

I have 2 peers, one is web browser, which is written in javascript, and another one is python script, which is working as signaling server and peer at the same time. So If you access to my web page, you will send video frame to server and then the server will make modification of that then send it back.

So I finished testing my app on LAN environment and everything worked as I expected. But once I deployed my app to remote server (Google cloud run) , I encountered Ice connection state failing issue. And gets this log on remote server.

enter image description here

(I think it is due to disconnection between peers, not low memory problem. I tried with 16GB RAM and 4 cpus and still didn't work)

Then, I dig into more information, and found that TURN/STUN server is necessary to build WebRTC app over Internet. So I added google STUN server to my RTCPeerConnection like this. [{'urls': 'stun:stun.l.google.com:19302'}, {'urls': 'stun:stun1.l.google.com:19302'}, {'urls': 'stun:stun2.l.google.com:19302'}] (I added both side on javascript and python because both side is working as peer) Unfortunately, it still didn't work.

Now, I am planning to build my own TURN server, but I am afraid if TURN server wouldn't solve this problem. So I would like to have any advice from you since I am quite stuck within my situation.

p.s I have done SSL encryption.(So GetUserMedia is working fine)

I want to change the exception format of Geoserver 2.8.2 WMS from default XML to inimage or blank. The docu states that this is possible (https://docs.geoserver.org/latest/en/user/services/wms/reference.html#exceptions), but does not tell how or where. Could anybody please tell me?

Thanks in advance!

Hi there, I am attempting to build a WebRTC client in Android that subscribes to a video feed that is being broadcast using NodeJS and JavaScript.

The broadcaster code can be viewed in its entirety in this lovely article by Gabriel Tanner.

It works beautifully when running it in localhost under the http://localhost:4000/broadcaster.html in Chrome and then visiting my IP Address from another device on the network. I can see the video and it is near real time.

I have tried this using two different webcam devices, both a built-in and a USB webcam but the Android client does not work even though the JavaScript Broadcaster and Client works fine.

After following the tutorial and getting the example to work I decided to try and implement my own Android application for which the entire source code can be viewed right here on my GitHub.

I have followed various tutorials around the place and the issue always stems from attempting to set the remote description which is done with the following bit of code:

I've been looking everywhere for days about my issue, but still can't find a good solution to this problem.

I had to do a project using openlayers, to create maps that are included in iframes on different cities websites, to show some informations on WMS layers (graves status in cemeteries, trash sorting policy, etc).

Everything works fine, except for one thing. When I zoom in or out, my app does a request to get the new WMS layers, I can see the request coming back, with the good image, but it doesn't render the map automaticaly when the request comes back. It does work perfectly while paning or using the geolocation button.

My current workaround is to add a map.render() in the "moveend" event of the app, with an adjustable delay to wait for the request.

I'm using a config file to transmit the map default coordinates, zoom and layers, so I'm wondering if the problem doesn't come from that, since my WMS layers are all created in an each loop.

Since the informations of that project are confidential I have to hide everything, but here is my code :
