Initial development of Hello Hubs is being supported by Projects For All. To learn more about Projects For All's use of Hello Hubs in education and community development, see Project Hello World. 3 Overview Overview A Hello Hub is a community-built & owned internet kiosk that provides education, communication, and community development resources. Each Hello Hub has two computer “terminals”, one server, one WiFi access point, one charging shelf, and one workbench. The Internet terminals provide a computer workstation that any student or community member (or group of community members) can use for a wide range of activities. There are a wide range of educational applications built into the kiosk system, as well as standard applications such as an office suite, media editing tools etc. Each terminal will have a fixed bench seat, where up to 4 users can comfortably access the terminal at one time. Each terminal will also have a built-in camera (for still, video and web video conversations), microphone, and speakers. The server's function is to load the system to the terminals, manage the Internet connection to the world, route traffic from the WiFi access point, conduct regular backups, provide administrative notifications about the health and status of the Hello Hub system, and record usage data for the community and its partners. (It should be noted that no recording of data will be conducted without the explicit consent of the community and users). Each Hello Hub will have a 24/7 WiFi access point providing an Internet connection for community members’ own devices, such as mobile phones, tablets, computers, or other devices that require WiFi access. Each Hello Hub will have a built-in electronics workbench with equipment for the maintenance of the Hello Hub itself. The workbench can also be used for community-led technical experimentation and innovation. Internet connection will vary with each Hello Hub, depending on the location and options available. The kiosk is powered by an off-grid solar power system. 4 Standard Design Standard Design This section outlines a standard Hello Hub "reference" design. The intention is to lay out a common design that can be easily altered to take into account local conditions and availability of materials. Standard Design Statement The Hello Hub will be a stand-alone structure, accessible from all sides. The central structure will be square or rectangular in shape, and will be covered by a overhanging roof to reduce weather and sun-glare during use. The roof will also serve as a mounting platform for the solar panels that provide power to the Hello Hub. The two opposing short sides will each contain a computer terminal, with the features described here (link is external). Set-back from each terminal will be a bench that can seat 4 users. One long side will contain access to the Hello Hub systems and control components, and the other long side will contain an electronic workbench and charging shelf. Each Hello Hub has two computer “terminals”, one server, one WiFi access point, one charging shelf, and one workbench. The Internet terminals provide a computer workstation that any student or community member (or group of community members) can use for a wide range of activities. There are a wide range of educational applications built into the kiosk system, as well as standard applications such as an office suite, media editing tools etc. Each terminal will have a fixed bench seat, where up to 4 users can comfortably access the terminal at one time. Each terminal will also have a built-in camera (for still, video and web video conversations), microphone, and speakers. The server's function is to load the system to the terminals, manage the Internet connection to the world, route traffic from the WiFi access point, conduct regular backups, provide administrative notifications about the health and status of the Hello Hub system, and record usage data for the community and its partners. (It should be noted that no recording of data will be conducted without the explicit consent of the community and users). Each Hello Hub will have a 24\/7 WiFi access point providing an Internet connection for community members’ own devices, such as mobile phones, tablets, computers, or other devices that require WiFi access. Each Hello Hub will have a built-in electronics workbench with equipment for the maintenance of the Hello Hub itself. The workbench can also be used for community-led technical experimentation and innovation. Internet connection will vary with each Hello Hub, depending on the location and options available. The kiosk is powered by an off-grid solar power system. 5 Standard Design Design Files: SketchUp File - Rapid Build 4-post structure 6 Standard Features Standard Features Rugged, site built structure: Built by community users, from local materials Wide roof providing shade and basic protection from the elements Fixed bench seats providing up to 4 spaces per terminal (8 seats per kiosk, with room for bystanders to participate) Easy access to internal equipment cabinets Stand-alone and self-sufficient 2 computer terminals consisting of: rugged and waterproof touch panel monitors mounted to opposite sides of the kiosk panel mounted rugged and waterproof keyboard below the monitor speakers, microphone and webcam The computer terminals provide a computer workstation that any student or community member (or group of community members) can use for a wide range of activities. There are a wide range of educational applications built into the kiosk system, as well as standard applications such as an office suite, media editing tools etc. Community WiFi access point: Each Hello Hub will have a 24\/7 WiFi access point providing an Internet connection for community members’ own devices, such as mobile phones, tablets, computers, or other devices that require WiFi access. Device Charging: Each Hello Hub will have a shelf for plugging in and charging user devices such as mobile phones and tablets (with 5VDC USB power requirement) Electronics workbench: Each Hello Hub will have a built-in electronics workbench with equipment for the maintenance of the Hello Hub itself. The workbench can also be used for community-led technical experimentation and innovation. Independent power and communications: solar or wind (or both) powered satellite network connectivity w\/ mobile network as backup Unified and personalized user experience: Each user will have a personal login to the system which will load a personalized desktop. Personal settings, files and activities will be saved to the individual user's login. The users personalized desktop is accessible from either terminal (by logging in) and from any terminal that is connected to the kiosk (in the case of an expanded roll-out to an adjacent community or learning facility. Modular systems: 7 Standard Features The kiosk systems are designed in a modular fashion, components can be easily deactivate, replaced, upgraded without the need for the whole kiosk to be taken offline. Built-in education and community tools The terminals will run a customized version of Edubuntu, which contains a large number of built-in educational resources. In addition to the base system resources, the kiosk will provide easy access to a community developed list of resources, both built-into the kiosk and internet-based. Remote access for maintenance and assistance Each Hello Hub is remotely accessible by community authorized support personnel, who can assist with any maintenance or systems problems, or upgrade requests! 8 Build: Structure & Hardware Structure & Hardware Build Guide This chapter contains instructions for building the Hello Hub structure and installing the system components. Preparing the site Building the structural frame. Installing the Solar PV power system Installing the Hello Hub kiosk components to the structure and connecting everything together! The Hello Hub is designed to be mostly built from off-the-shelf parts, as well as to allow for flexibility and local conditions. 9 Preparing the Site Preparing the Site In most cases, the Hello Hub will be build on top of a small concrete slab. The concrete slab provides a stable base for the Hello Hub structure to attach to, as well as a foundation for the benches to be built upon.

  • Ultumix GNU/Linux 0.0.1.7 32 Bit!
    Welcome to Ultumix GNU/Linux 0.0.1.7 32 Bit! What is Ultumix GNU/Linux 0.0.1.7? Ultumix GNU/Linux 0.0.1.7 is a full replacement for Microsoft©s Windows and Macintosh©s Mac OS for any Intel based PC. Of course we recommend you check the system requirements first to make sure your computer meets our standards. The 64 bit version of Ultumix GNU/Linux 0.0.1.7 works faster than the 32 bit version on a 64 bit PC however the 32 bit version has support for Frets On Fire and a few other 32 bit applications that won©t run on 64 bit. We have worked hard to make sure that you can justify using 64 bit without sacrificing too much compatibility. I would say that Ultumix GNU/Linux 0.0.1.7 64 bit is compatible with 99.9% of all the GNU/Linux applications out there that will work with Ultumix GNU/Linux 0.0.1.7 32 bit. Ultumix GNU/Linux 0.0.1.7 is based on Ubuntu 8.04 but includes KDE 3.5 as the default interface and has the Mac4Lin Gnome interface for Mac users. What is Different Than Windows and Mac? You see with Microsoft©s Windows OS you have to defragment your computer, use an anti-virus, and run chkdsk or a check disk manually or automatically once every 3 months in order to maintain a normal Microsoft Windows environment. With Macintosh©s Mac OS you don©t have to worry about fragmentation but you do have to worry about some viruses and you still should do a check disk on your system every once in a while or whatever is equivalent to that in Microsoft©s Windows OS.

  • A Platform for Benchmarking and Comparing Outcome Prediction Methods in Precision Cancer Medicine Noah Eyal-Altman1* , Mark Last2 and Eitan Rubin1
    Eyal-Altman et al. BMC Bioinformatics (2017) 18:40 DOI 10.1186/s12859-016-1435-5 SOFTWARE Open Access PCM-SABRE: a platform for benchmarking and comparing outcome prediction methods in precision cancer medicine Noah Eyal-Altman1* , Mark Last2 and Eitan Rubin1 Abstract Background: Numerous publications attempt to predict cancer survival outcome from gene expression data using machine-learning methods. A direct comparison of these works is challenging for the following reasons: (1) inconsistent measures used to evaluate the performance of different models, and (2) incomplete specification of critical stages in the process of knowledge discovery. There is a need for a platform that would allow researchers to replicate previous works and to test the impact of changes in the knowledge discovery process on the accuracy of the induced models. Results: We developed the PCM-SABRE platform, which supports the entire knowledge discovery process for cancer outcome analysis. PCM-SABRE was developed using KNIME. By using PCM-SABRE to reproduce the results of previously published works on breast cancer survival, we define a baseline for evaluating future attempts to predict cancer outcome with machine learning. We used PCM-SABRE to replicate previous work that describe predictive models of breast cancer recurrence, and tested the performance of all possible combinations of feature selection methods and data mining algorithms that was used in either of the works. We reconstructed the work of Chou et al. observing similar trends – superior performance of Probabilistic Neural Network (PNN) and logistic regression (LR) algorithms and inconclusive impact of feature pre-selection with the decision tree algorithm on subsequent analysis.
