and when I ran
adb uninstall io.appium.uiautomator2.server; adb uninstall io.appium.uiautomator2.server.test; adb uninstall io.appium.unlock (was throwing error); adb uninstall io.appium.settings
I got the following error

NWJS (Node Webkit) app is not responding on Linux systems when I use it with Web Workers

NWJS Version: v.0.32.1 (Tested on different 0.31 versions also and 0.32.beta)
Operating System: Linux only. Tested on Ubuntu 16.04 LTS x64 and Elementary OS 0.4.1 Loki x64
Expected behaviour
The program must respond.
Actual behaviour
The program not responding and if I break it (Ctrl + C) i seen in console that messages:
[14399:14410:0802/142733.750943:ERROR:broker_posix.cc(104)] Error sending sync broker message: Broken pipe (32)

But if I'am using nwjs-builder-phoenix and running SDK - working correctly.
How to reproduce
Prepare
Download and extract fake data to parsing: https://github.com/trofivan/myq-jobs-archive-parser/releases/download/v0.1.0/fake-data-big.zip
git clone https://github.com/trofivan/myq-jobs-archive-parser.git
cd myq-jobs-archive-parser
npm i
Working correctly (only with nwjs-builder-phoenix SDK)
npm start
In the opened window click Select folder to parse
Select folder with fake data
Wait some time while data will have parsed.
Use filters
Close the program
Working not correctly
npm run build.dist
cd dist/myq-jobs-archive-parser-0.1.3-linux-x64/
./myq-jobs-archive-parser
Select folder to parse and waiting some time.
The program does not respond.
Close program (Ctrl + C or [x] on the window) and see console output:
Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.

killall exe - to stop the process
PS:
If download nwjs from the official website, working not correctly with SDK version also.
On Linux system program not responded when comes to the game Web Worker: https://github.com/trofivan/myq-jobs-archive-parser/blob/master/src/middlewares/fetchJobs.js
When program not responding I'm can not open Chrome dev tools and get more info.

Azure-IoT - Raspberry pi3 Forever script exited with code: 7

I'm running a forever script sending data from raspberry pi 3 to azure-iot-hub, using the following,
root#raspberrypi3:~# forever start /home/pi/azure/iam/ble_azure.js
After working for about 1.5 days, I stopped getting messages at auzre-iot-hub, when I checked forever list I got the following:
root#raspberrypi3:~# forever list
info: Forever processes running
data: uid command script forever pid id logfile uptime

When I checked the log file I get this error message:

[IoT hub Client] Connect error: mqtt.js returned premature close error
Through the log file, mqtt error keeps happening multiple times and forever handled it successfully, what I can't understand why after 1.5 days, I get this error:
**error: Forever detected script exited with code: 7
error: Script restart attempt #34**
Also why I keep getting such mqtt error, why it keeps disconnecting?
**NotConnectedError: mqtt.js returned client disconnecting error**

If you're using Client.fromConnectionString to instantiate the client object the SDK disconnects and reconnects every 45 minutes to renew the shared access signature token. (it doesn't happen with AMQP that uses a different authentication mechanism). It might be that when re-establishing the connection the client hits this "premature close" error that we've been tracking in this issue.
There are 2 things that could help limit potential errors linked to disconnecting/reconnecting:
Use X509 certificates instead of connection strings to authenticate.
Create a client object using Client.fromSharedAccessSignature and build a long-lived signature that does not require disconnecting and reconnecting as often.
Last but not least, the next release of the SDK (1.2.0) will include a retry/reconnect logic that is way more robust than what was there before. I'll update the issue to point to it when it is released.

Nodejs to Couchbase Server timed out

My app is actually running fine when I started it and keep an eye on it for few hours.
BUT later time(I'm not sure what exact time of inactivity), It does show "Server timed out" (I crop some logs below)
[ERROR] (server - L:463) <node.mycouchbase.server:11210> (SRV=0x2111c60,IX=4) Server timed out. Some commands have failed
[INFO] (confmon - L:166) Not applying configuration received via CCCP. No changes detected. A.rev=152466, B.rev=152466

[INFO] (cccp - L:110) Re-Issuing CCCP Command on server struct 0x2185e30
All just working fine again when I restart my Node.js app (Expressjs app).
This problem seem regularly happening
Please give me some suggestion what could be actually problems behind.
Thanks

Debug error when debugging OpenGL program remotely

I can use gdb to debug my OpenGL program on the server locally. But when I Debug it remotely. some errors come out in glutCreateWindow() function. And I can run my program remotely. Just can't debug .
freeglut (/home/fshen/samuel/project_self/GLSL-learning/teapotshader/teapotshader):
ERROR: Internal error <FBConfig with necessary capabilities not found> in
function fgOpenWindow
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 4 (X_DestroyWindow)
Resource id in failed request: 0x0
Serial number of failed request: 20
Current serial number in output stream: 23
PS:
First I can't run my program remotely. After setting export LIBGL_ALWAYS_INDIRECT=yes (I put this command in .bash_profile),I can run my project. Just can't debug it remotely. So I think i should add export LIBGL_ALWAYS_INDIRECT=yes into the GDB. But I don't know howto do it?
