Drummond stresses that the system is designed to safeguard privacy. For example, when a user visits a page--nominating it for Wowd's index in the process--that page is actually accessed and indexed by a different user's computer. This process protects against accidentally collecting information that is protected by passwords or cookies. The site also does not index any pages protected by encrypted Internet protocols.
Wowd doesn't simply report on what its users are doing in real time, as some Twitter search engines do, for example. Instead it uses its own algorithms that balance a page's freshness against its apparent popularity. When searching in Wowd, a user can choose to see results ranked by popularity or by freshness. In either case, the page will automatically update and adjust its results over time if the user leaves it up.

Securing the web

MIT WebTech Programming

Resin, which automatically calls up security checks whenever they're required, even in unforeseen circumstances.
Typically, web programmers will associate security checks with particular application functions. If you belonged to a social-networking site, for instance, you might be able to e-mail your friends, or post remarks on their pages, or comment on their own posts, or tag their pictures, and so on. Each of these operations executes its own chunk of code, and the developer will usually attach a security check to each chunk, to ensure that the user is authorized to invoke it. (These types of security checks operate in the background: they don't require you, for instance, to reenter your user name and password.) Many web applications also "sanitize" data posted by their subscribers: if a friend posts something to your social-network page, the application probably won't show you the post without inspecting it for malicious code.

- a system that associates security checks with particular chunks of data rather than with particular chunks of code. Any attempt to access the data, by any imaginable route, invokes the check.
- For programmers, the new system should be easy to adopt. They're already writing code for security checks and sanitization anyway; now, they'd have to write it only once, instead of pasting it into their programs in hundreds of different places.
- But the MIT system relies on additional software that tracks data as they flow through an application, to make sure that security rules remain associated with the information wherever it's being stored and however it's being used. And the data tracker presents the biggest obstacle to commercial adoption.
- Web applications need to run on any type of computer, regardless of the operating system or web browser being used, so web languages like Python and PHP require an extra layer of software called a "runtime" to translate code into the language spoken by a given machine. Generally, the organizations that develop new programming languages also maintain the runtimes, which undergo sequential releases, just like any commercial program. The MIT system's data tracker would have to be incorporated into several different languages' runtimes, which could be a hard sell.

Technology Explained: Understanding The Internet Speed

Internet WebTech

It’s like you sending a Smart Car to request that they send you a fleet of tractor trailers. You only need one lane for the Smart Car, but you might need 14 lanes for the tractor trailers. This is known as asynchronous communications. This is why your upload speed is usually less than your download speed.
those speed tests don’t measure jitter! Yes, jitter is a real technical term. Imagine a train coming into the station. Each car on that train arrives at the station at the same intervals, because each car is the same distance apart. However, if each car came in with different distances between the cars, well, you can imagine what a mess that would make!

It’s the same thing for packets of information on the Internet. The fluctuation of the time between those packets, even if ALL the packets are traveling at 3Mbps causes jitter. Significantly high jitter levels can cause your VoIP to not work. When we talk our voice is a continuous stream of information, so the data needs to be continuous too! Same with video!

- Another cause of Internet speed not being what it seems, is the number of hops a communication needs to make to get to the final server.
- Your Internet router may be capable of less speed than your Internet connection. That’s a bottleneck. Your Network Interface Card may be capable of less speed than your router. That’s a bottleneck. Your video card may only be capable of processing the information at a lower speed than your NIC card can deliver it to your computer. There’s another bottleneck.
- your bandwidth may be getting divided amongst a number of computers in your home.

Looking ahead, new Web sites will be created that pull together clusters of information that are tightly linked. The network of networks that we find on Facebook will be applied to the Web. No longer will you need to go to a dozen car sites or an aggregator like Autobytel or even Google to find information about the best hybrid SUV. Instead, the Internet will create a page with only the most interesting and relevant information across the Net.
An example of what Stibel means is start-up called Kosmix.com, which touts the idea of “dynamic portals.”

ITS Traffic WebTech

The website presentation layer relies on Google Maps – a well-known web utility - and the use of cutting-edge AJAX (Asynchronous JAvaScript and XML) techniques, while the underlying core technology is RACC traffic aggregation server. The server applies several ad hoc algorithms to normalise traffic data feeds, both for dynamic (road congestion, road works, accidents, mountain pass reports, weather events) and static data (black spots, speed cameras, risk mapping per road stretch and tunnels as provided by the EuroRAP and EuroTAP programmes).
The website is characterised by its highly accurate real-time information about situation of the traffic incidents (dynamic data), useful points of interest (static data), compatibility with all major PND’s for static data downloading, ease of use (the well-known Google Maps user interface), customisability (different layers of data available by request) and performance (AJAX allows the website to be highly interactive and behave like a local application).

Representational State Transfer - Wikipedia, the free encyclopedia

WebTech

Representational state transfer (REST) is a style of software architecture for distributed hypermedia systems such as the World Wide Web. The term Representational State Transfer (REST) was introduced and defined in 2000 by the doctoral dissertation of Roy Fielding,^[1]^[2] one of the principal authors of the Hypertext Transfer Protocol (HTTP) specification versions 1.0 and 1.1.
