When I was trying to download dependencies for my go project in an old Ubuntu machine I was getting this error all the time: "go: gopkg.in/alexcesaro/quotedprintable.v3@v3.0.0-20150716171945-2caba252f4dc: Get "https://proxy.golang.org/gopkg.in/alexcesaro/quotedprintable.v3/@v/v3.0.0-20150716171945-2caba252f4dc.mod": tls: failed to verify certificate: x509: certificate signed by unknown authority" Which the main part of it was go get failing to authenticate: " tls: failed to verify certificate: x509: certificate signed by unknown authority " I tried many things but couldn't make it work until I found the way: export GOINSECURE="proxy.golang.go" This will tell go get to ignore certification validity.

This system was running on Windows Server 2012, with php version 5.5.6 and Apache 2.4. Very old versions of software. The system was sending emails using the php smtp package and old libssl.dll which supports only TLSv1.0. The smtp service they were using (AWS SES Simple Email Service) has recently dropped the support for SMTP connection via TLS version 1.0. Now in order to support TLS v1.2 for emails on smtp I have to upgrade the whole system. Windows version, php version, Apache version and more - this would have taken me a very long time with many obstacles on the way. Amazon support:  https://docs.aws. amazon.com/ses/latest/dg/ security-protocols.html The solution I have chosen was to write this proxy, so calls fro

If you wish to create a virtual camera in Linux and stream "fake" videos during calls: To install the loopback camera: sudo apt update sudo apt install v4l2loopback-dkms v4l2loopback-utils To add the loopback camera module: sudo modprobe v4l2loopback card_label="My Fake Webcam" exclusive_caps=1 or sudo modprobe v4l2loopback devices=1 video_nr=1 card_label='MyWebCam' exclusive_caps=1 Now to stream the video: First find the list of videos device available: v4l2-ctl --list-devices You can check the videos by playing: ffplay /dev/videoX ffplay Rick_Astley_Never_Gonna_Give_You_Up.mpg Now you can stream the video to the free one: ffmpeg -re -i Rick_Astley_Never_Gonna_Give_You_Up.mpg -map 0:v -f v4l2 /dev/videoX Or ffmpeg -stream_loop -1 -re -i video.mp4 -vcodec rawvideo -threads 0 -f v4l2 /dev/videoX To remove the module from the kernel: sudo modprobe --remove v4l2loopback Software for streaming: sudo apt-add-repository ppa:obspro
