The release of the Porteus Kiosk 4.8.0 distribution kit, based on Gentoo, is designed to equip stand-alone internet kiosks, display booths and self-service terminals. The boot image of the distribution is 93 MB.

The basic build includes only the minimum set of components required to launch a web browser (Firefox and Chrome are supported), which is reduced in its capabilities to prevent unwanted activity in the system (for example, setting changes are not allowed, application download / install is blocked, access to selected pages). Additionally, specialized Cloud assemblies are offered for comfortable work with web applications (Google Apps, Jolicloud, OwnCloud, Dropbox) and ThinClient for working as a thin client (Citrix, RDP, NX, VNC and SSH) and Server for managing a network of kiosks.

Setup is done through a special wizard, which is combined with the installer and allows you to prepare a customized version of the distribution for placement on a USB Flash or hard drive. For example, you can set a default page, define a white list of allowed sites, set a password for the guest login, define an inactivity timeout to end a session, change the background image, adjust the browser design, add additional plug-ins, enable wireless network support, configure keyboard layout switching and more. 

When loading, verification of system components by checksums is performed, and the system image is mounted in read-only mode. Updates are installed automatically using the mechanism of formation and atomic replacement of the system image as a whole. It is possible to centrally configure a group of typical Internet kiosks remotely with configuration loading over the network. Due to the small size, the default distribution is loaded entirely into RAM, which allows to significantly increase the speed of work.

Nuitka 0.6.6 to be Released

This compiler allows to translate a Python script into a C ++ representation, which can then be compiled into an exe file using libpython

Nuitka 0.6.6 has been released. This is a compiler that allows you to translate a Python script into a C ++ representation, which can then be compiled into an executable file using libpython to ensure maximum compatibility with CPython (using regular CPython tools for managing objects) . Fully compatible with current releases of Python 2.x and 3.x. Compared to CPython, compiled scripts show up to 312% higher performance in pystone tests. Project code is distributed under the Apache license.

The new version adds experimental support for Python 3.8 and provides compatibility with libraries and applications sklearn, osgeo, gdal, dill, scikit-image, skimage, weasyprint, dask, pendulum, pytz and pytzdata. Distutils adds support for individual modules (py_modules, not just packages) and packages with separate namespaces. Work with variables in loops has been optimized and optimized options for the abs and all built-in functions have been implemented, as well as accelerated operations with int and long types. Numerous improvements have been made to reduce memory consumption.
In addition, it is possible to postpone the end of support for the Python 2 branch from January to April. In April 2020, the last final update of the Python 2.7 branch will be generated, after which the corrective releases will not be published. At the same time, work on fixing vulnerabilities in Python 2.7 will be continued by community representatives who are interested in continuing to support this branch in their products. For example, Red Hat will continue to maintain packages with Python 2.7 throughout the entire life cycle of RHEL 6 and 7 distributions, and for RHEL 8 it will generate package updates in the Application Stream until June 2024. Recall that the Python 2.7 branch was formed in 2010 and it was originally planned to stop supporting it in 2015, but due to the insufficiently active migration of projects to Python 3, the lifetime of Python 2 was extended to 2020.
