Free and Open Source solutions

Ugo Vallauri
Computer Aid International

Computer Aid International
 The world's largest not-for-profit provider of
practical ICT solutions for development

More than 155,000 PCs shipped in over 100
countries
 Currently providing 100% Pentium 4 PCs

Working on projects with local
partners across Africa
 Telemedicine (with Amref in East Africa)

 Rural access to ICT and the Internet
(with LinkNet in Zambia)

Support to users with visual disabilities
(with Kenyan Union of the Blind)

The reality

Millions of potential computer users
across Sub-Saharan Africa
Can not afford proprietary solutions
screen readers and magnifiers

An alternative model:

Free and Open Source Software

Why is it relevant?
Users can download, share and freely copy the
software

The code can be improved by a community of
developers

 Low-priority features can be added by external
programmers (ie. Support for local languages)

An example: NVDA
 It started as a small project

 Today it is the best portable, freely available
screen reader for Windows

 Not “perfect” but it keeps improving

 Download it at www.nvda-project.org

What's missing: A Free and
Open Source Magnifier
 Native Screen Magnification in Operating Systems
is poor

 Great potential for integration with NVDA

Computer Aid is working with partners to develop it

The big picture:
A free and portable solution
Integrate free and open source Magnifier, Screen
Reader, Browser adapted for disabilities, anti-virus

 Make it available as download and distribute it as
a USB stick

 A solution targeted to the Global South, but useful
in the UK as well

A little voluntary based, self financed Open Hardware PowerPC notebook motherboard project could attract important changes in the Electronic Industry, inducing a Butterfly Effect. Open Hardware, Free Software and 3D Printing are game changer in the electronic industry; they could decentralize and democratize electronic manufacturing, acknowledgment and evenly distribute advantage factors. Starting with concrete examples, the OSWH PowerPC Notebook motherboard based on Cern Open Hardware License v 1.2 will be included. Fine tuning and fixing PowerPC 64bit Debian packages and FreeCad for design the Open Hardware Notebook Chassis will be presented.

Global problems need global solutions! In a time when humanity needs to work together to find solutions for a crisis, we cannot afford to reinvent the wheel again and again. Global problems need global solutions! It is Free Software that enables global cooperation for code development. Any proprietary solution will inevitably lead to countless isolated solutions and waste energy and time which we as humanity cannot afford in such a critical situation. Free Software licences allow sharing of code in any jurisdiction. Solutions developed in one country can be reused and adapted in another one. International development agencies and humanitarian movements can help to contain the spread of COVID-19 in any country around the world with the availability of Free Software solutions. Already before this crisis hundreds of organisations and tens of thousands of people demanded that publicly financed software developed for the public sector must be made publicly available under Free Software licences. It is now even more important than ever before to tackle this crisis. Do you want to promote Free Software as well? Then the campaign framework of “Public Money? Public Code!” might be the right choice for you; no matter if you want to do it as an individual or as a group; no matter if you have a small or large time budget.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.

Why Teams call analytics are critical to your entire business

With more memory available, system performance of three Dell devices increased, which can translate to a better user experience Conclusion When your system has plenty of RAM to meet your needs, you can efficiently access the applications and data you need to finish projects and to-do lists without sacrificing time and focus. Our test results show that with more memory available, three Dell PCs delivered better performance and took less time to complete the Procyon Office Productivity benchmark. These advantages translate to users being able to complete workflows more quickly and multitask more easily. Whether you need the mobility of the Latitude 5440, the creative capabilities of the Precision 3470, or the high performance of the OptiPlex Tower Plus 7010, configuring your system with more RAM can help keep processes running smoothly, enabling you to do more without compromising performance.
