CLAT for Linux using Jool and ipvlan PoC

CLAT for Linux using ipvlan

This proof of concept uses ipvlan feature of Linux to split up main network interface into two in order to use one in a separate namespace with jool-siit performing CLAT translation.

This way, enabling CLAT is least intrusive to the default network namespace - no need to enable forwarding or touch firewall rules.

This gist shows you how to encode specifically to HEVC with ffmpeg's NVENC on supported hardware, with a two-pass profile and optional CUVID-based hardware-accelerated decoding.

Encoding high-quality HEVC content in a two-pass manner with FFmpeg - based NVENC encoder on supported hardware:

If you've built ffmpeg as instructed here on Linux and the ffmpeg binary is in your path, you can do fast HEVC encodes as shown below, using NVIDIA's NPP's libraries to vastly speed up the process.

Now, to do a simple NVENC encode in 1080p, (that will even work for Maxwell Gen 2 (GM200x) series), start with:

ffmpeg  -i <inputfile> -pass 1 \
-filter:v hwupload_cuda,scale_npp=w=1920:h=1080:format=nv12:interp_algo=lanczos,hwdownload,format=nv12 \

-c:v hevc_nvenc -profile main -preset slow -rc vbr_2pass \

Compress PDF files with ghostscript

This can reduce files to ~15% of their size (2.3M to 345K, in one case) with no obvious degradation of quality.

ghostscript -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf

Other options for PDFSETTINGS:

  • /screen selects low-resolution output similar to the Acrobat Distiller "Screen Optimized" setting.
  • /ebook selects medium-resolution output similar to the Acrobat Distiller "eBook" setting.
  • /printer selects output similar to the Acrobat Distiller "Print Optimized" setting.
  • /prepress selects output similar to Acrobat Distiller "Prepress Optimized" setting.

Setting up Nginx, uWSGI & Python3
======================================
Setting up Nginx, uWSGI and Python3
======================================
First off, I'm traditionally a PHP developer, but am looking at moving across to Python. I really struggled to find decent documentation on how to get a server up and running for deploying Python web applications from the point of view of someone coming from PHP. The main problems I came across with documentation were:
1) Only showed you how to run the server for a single web application.
2) Only showed you how to configure the app, not the server it was running on.
My preferred workflow for development is by setting up a new VM in VMware Fusion and then forwarding through all requests to that VM via /etc/hosts. This might not be the optimal way to get things up and running, but it works for me.
