IPFire
From a technical point of view, IPFire is a minimalistic, hardened firewall system which comes with an integrated package manager called Pakfire. The primary task of Pakfire is to update the system with only a single click.
It is very easy to install security patches, bugfixes and feature enhancements, which make IPFire safer and faster – or simply, better.
Another task of Pakfire is to install additional software that adds new functionality to the IPFire system.
Some useful of them are:
- File sharing services such as Samba and vsftpd
- Communications server using Asterisk
- Various command-line tools as tcpdump, nmap, traceroute & many more.
Smoothwall.org
The goals of the project can be summed up as:
- Be simple enough to be installed by home users with no knowledge of Linux
- Support a wide variety of network cards, modems and other hardware
- Work with many different connection methods and ISPs from across the world
- Manage and configure the software using a web browser
- Run efficiently on older, cheaper hardware
- Develop a supportive user community
- Use sponsorship from Smoothwall Limited to further these goals
The Smoothwall Open Source Project is funded and supported by Smoothwall Limited.

Runs Linux
Fantastic show, keep up the good work.
I wanted to share my own small runs Linux with you. I’m an IT Tech working in a secondary school in the UK. I got fed-up of our old outdated lesson change bell system from the 70’s so i made a pi powered one. It uses cron to run a python script that turns the relay on for a set amount of time. The cron file is edited via the UI that runs on php, MySQL on top of Apache. Photos of the UI and the project build attached.
its been in production since feb and still going strong.Hope you like it
Thanks

Organize files into libraries. A library can be selectively synced into any device. Reliable and efficient file syncing improves your productivity.
A library can be encrypted by a password chosen by you. Files are encrypted before syncing to the server. Even the system admin can’t view the files.
Sharing into groups and collaboration around files. Permission control, versioning and activity notification make collaboration easy and reliable.
The core of Seafile server is written in C programming language. It is small and has a fantastic performance.
Upgrade can be done via running a simple script within a few seconds. Seafile records very few items in database. No huge database upgrade is needed.
AD/LDAP integration, group syncing, fine-grained permission control make the tool easily applied to your enterprise environment.

BONUS SPOTLIGHT
Online tracking has become a pervasive invisible reality of the modern web. Most sites you load are likely to be full of ads, tracking pixels, social media share buttons, and other invisible trackers all harvesting data about your web browsing. These trackers use cookies and other methods to read unique IDs associated with your browser, the result being that they record all the sites you visit as you browse around the internet. This sort of tracking is invisible to most web users, meaning they never get the option to agree to or opt-out of it. Today the EFF has launched the 1.0 version of Privacy Badger, an extension designed to prevent these trackers from accessing unique info about you and your browsing.

Firefox exploit found in the wild | Mozilla Security Blog
Yesterday morning, August 5, a Firefox user informed us that an advertisement on a news site in Russia was serving a Firefox exploit that searched for sensitive files and uploaded them to a server that appears to be in Ukraine. This morning Mozilla released security updates that fix the vulnerability. All Firefox users are urged to update to Firefox 39.0.3. The fix has also been shipped in Firefox ESR 38.1.1.
LibreOffice 5.0 Released!
It is also the first version to come in 64 bits for Windows. As such LibreOffice 5 serves as the foundation of our current developments and is a great platform to extend, innovate and collaborate with!
LibreOffice 5.0 ships an impressive number of new features for its spreadsheet module, Calc: complex formulae image cropping, new functions, more powerful conditional formatting, table addressing and much more. Calc’s blend of performance and features makes it an enterprise-ready, heavy duty spreadsheet application capable of handling all kinds of workload for an impressive range of use cases.
New icons, major improvements to menus and sidebar : no other LibreOffice version has looked that good and helped you be creative and get things done the right way. In addition, style management is now more intuitive thanks to the visualization of styles right in the interface.
LibreOffice 5 ships with numerous improvements to document import and export filters for MS Office, PDF, RTF, and more. You can now timestamp PDF documents generated with LibreOffice and enjoy enhanced document conversion fidelity all around.
LibreOffice 5 combines innovative features and long term efforts towards enhanced stability. As a result, expect both improvements in performance and in stability over the lifetime of the 5.0.x series.
LibreOffice under the hood: progress to 5.0
Gtk3 backend: Wayland
An very rough, initial gtk3 port was hacked together long ago by yours truly to prototype LibreOffice online via gdk-broadway.
However thanks to Caolán McNamara (RedHat) who has done the 80% of the hard work to finish this, giving us a polished and complete VCL backend for gtk3.
His blog entry focuses on the importance of this for running LibreOffice natively under wayland – the previous gtk2 backend was heavily tied to raw X11 rendering, while the new gtk3 backend uses CPU rendering via the VCL headless backend, of which more below.
OpenGL rendering improvements
The OpenGL rendering backend also significantly matured in this version, allowing us to talk directly to the hardware to accelerate
much of our rendering, with large numbers of bug fixes and improvements.
Many thanks to Louis-Francis Ratté-Boulianne (Collabora), Markus Mohrhard, Luboš Luňák (Collabora), Tomaž Vajngerl (Collabora), Jan Holesovsky (Collabora), Tor Lillqvist (Collabora), Chris Sherlock & others.
It is hoped that with the ongoing bug-fixing here, that this can be enabled by default as a late feature, after suitable review, for LibreOffice 5.0.1 or at the outside 5.0.2.
LibreOffice 5.0 Is a Milestone Release for Ubuntu Touch
LibreOffice will land on Ubuntu Touch
The developers from The Document Foundation haven’t gone into much detail about their plans, but they have said that the office suite is coming to Android. Coupled with the things we already know about Ubuntu Touch, we can safely say that LibreOffice 5.0 will bring some very interesting changes to the mobile platform from Canonical.
“A new version for new endeavours: LibreOffice 5.0 is the cornerstone of the mobile clients on Android and Ubuntu Touch, as well as the upcoming cloud version. As such, LibreOffice 5.0 serves as the foundation of current developments and is a great platform to extend, innovate and collaborate!” reads the announcement from The Document Foundation.
Jolla Tablet – First Batch out of Factory
Last week was very busy for Jolla, but few issues delaying the process by couple of days were catch up during the weekend by hard working Sailors. The first batch of Jolla Tablets is now complete and is told to look great! This batch is pre-production batch delivered to selected developers and internal test personnel
July 27th all the components were ready to be mounted on the circuit boards in China. All that was missing was the circuit boards themselves, as the flight delivering them was delayed by couple of hours. This delay was short, and assembling the boards was started as planned without major issues.
Earlier delays with material preparation and board delivery forced Jolla to agree on a new schedule with the assembly factory. July 30th, circuit boards were tested and the batch was sent to factory to be assembled on the next day. Surprise came with a glue machine, display assembly wasn’t possible
White House Petition to use FOSS whenever possible
We believe that the federal government, for the security of the information it manages and the efficient allocation of the public’s funds, should divest itself of costly proprietary software contracts wherever possible.
Healthcare.gov’s initial failings had much to do with the old, proprietary infrastructure that government contracting details required the application be built on. The US Navy recently spent considerable amounts of taxpayer money to extend support for Windows XP and Office 2003, both inherently obsolete and insecure.
Use of proprietary software costs our taxpayers needless money. It’s become clear that governments such as those of the UK and much of the European Union can adopt open source software and be better off for it. We should join them.
