A Universal Time Script
I would like to specify somewhere deep in the operating system that any command line command that takes longer than a specified amount of time should automatically be terminated or cancelled and return to the shell prompt.
A Universal Time Script
I have an universal windows app which is deployed to Raspberry PI 3 with windows iOT Core, the PI 3 can have many sensors connected, therefore those sensors need to be registered with Azure IOT Hub, in order to do that I register them manually with Device Explorer, and then on an XML file I created, I put the Device Key and other configuration settings.
However I dont know if this way of configuration is the best practice for universal windows app, first than all, I dont know how to edit that XML file before installing the package, or after its installed I dont know where to find the file and edit it before the app runs.
The Internet is a popular tool for educators. Faculty members can post syllabi and other course materials on websites. They can also provide links to useful resources for students. Much of the Internet's power comes from the fact that it presents information in a variety of formats while also cataloging information in a searchable manner. Unfortunately, due to the multimedia nature of the web, combined with the poor design of some websites, many students and other web users cannot use the full range of resources this revolutionary tool provides.
For example, some visitors cannot see graphics because of visual impairments or cannot hear audio because of hearing impairments. Some users have difficulty navigating sites that are poorly organized with unclear directions because they have learning disabilities, speak English as a second language, or are younger than the average user. Other visitors use older equipment or slow connections or modems that limit access to multimedia features.
It is important to keep in mind that the people in this video might be accessing your website. To create resources that can be used by the widest spectrum of potential visitors rather than an idealized average, website designers should apply universal design principles. They should consider the special needs of individuals with disabilities, individuals older or younger than the average user, people for whom English is a second language, and those using outdated hardware and software.
Designing a product or service involves the consideration of myriad factors that include aesthetics, engineering options, environmental issues, safety concerns, and cost. One issue that designers often overlook is that of universal design.
Universal design is defined by the Center for Universal Design at North Carolina State University as "the design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design." At the center, a group of architects, product designers, engineers, and environmental design researchers collaborated to establish a set of principles of universal design to provide guidance in the design of environments, communications, and products.
General principles of universal design require that the design is useful and marketable to people with diverse abilities; the design accommodates a wide range of individual preferences and abilities; the design communicates necessary information effectively to the user, regardless of ambient conditions or the user's sensory abilities; the design can be used efficiently and comfortably, and with a minimum of fatigue; and appropriate size and space is provided for approach, reach, manipulation, and use regardless of user's body size, posture, or mobility.
Universal design techniques can be applied in the design of packaging, software, appliances, transportation systems, physical spaces, and many other products, services, and environments. Examples of universal design in architecture are ramps, automatic door openers, and Braille labels on elevator control buttons. Following universal design principles in creating a website provides access to all users regardless of their abilities, their disabilities, or the limitations of their equipment and software.
When universal design principles are applied to the design of webpages, people using a wide range of adaptive technology can access them. The World Wide Web Consortium (W3C), an industry group founded in 1994 that develops common protocols which enhance interoperability and guide the evolution of the web, has taken a leadership role in this area. The W3C is committed to promoting the full potential of the Internet to ensure a high degree of usability by people with disabilities.
As stated by Tim Berners-Lee, W3C Director and inventor of the World Wide Web, "The power of the web is in its universality. Access by everyone regardless of disability is an essential aspect." The Web Accessibility Initiative (WAI) coordinates W3C's efforts with organizations worldwide to promote accessibility. Its Web Content Accessibility Guidelines tell how to design webpages that are accessible to people with a wide variety of disabilities.
When it is not possible to use an accessible technology, an alternative version of the content should be provided. However, webpage designers should resort to separate, accessible pages only when other solutions fail. Maintaining a separate page is time consuming. Alternative pages tend to be updated less frequently than "primary" pages and, therefore, often provide outdated information to the site visitors using them.
"The DO-IT pages form a living document and are regularly updated. We strive to make them universally accessible. We minimize the use of graphics and photos, and provide descriptions of them when they are included. Video clips are open captioned, providing access to users who can't hear the audio, and audio described for those who cannot see the visual display. Suggestions for increasing the accessibility of these pages are welcome."
Test your website with as many web browsers as you can, and always test your website with at least one text-based browser, such as Lynx, and with the audio- graphics-loading of a multimedia browser turned off. This way, you will see your web resources from the perspectives of people with sensory impairments.
If universal design principles are employed in website development, other people besides individuals with disabilities will also benefit from the design. They include people working in noisy or noiseless environments; people whose hands or eyes are occupied with other activities; people for whom English is a second language; people using older, outdated equipment; and individuals using monochrome monitors.
I hope this program has given you a clear understanding of the impact that the combination of computers, adaptive technology, and electronic resources can have on the lives of people with disabilities. Faculty and administrators have a legal responsibility to ensure equitable access to resources and services. The information provided in this program should have given you tools to begin implementing universal design principles when developing and updating websites. Applying these guidelines will help level the playing field for people with disabilities.
I stumbled across this yesterday, and was excited to try it. We successfully added the script to our beta environment and started playing, but the fact that you always get kicked back to the Home page means you're not saving a lot of time or clicks with the script versus without. I love the idea, but I'd love it more if it toggled to the student view of the page you're on (which is what our faculty have been asking for), rather than navigating away. Any idea how daunting a scripting challenge that would be?
I am hopeful that Instructure will update/modify their UI/UX in the future, so that there is a persistent Student View button that you can simply click at any time to turn it on/off on the page that you are currently on.
One possibility, not flushed out and probably not worth pursuing, would be to write current location and timestamp somewhere (browser local storage, cookie, or custom user data) and then query that on every page load to see if that information is available and recent. The browser's local storage or a cookie would be faster since it wouldn't require a network call for every page. If the information exists and the timestamp is within a few seconds of when it was set, then you can redirect on the page load. You can destroy the information as soon as you've read it and determined that a redirect is necessary. 041b061a72
