Peacock launched in April for some Comcast cable customers, and will be available to the general public starting July But most of its shows can also be seen on NBC, for free, and many are also on Hulu until their licensing contracts expire, at least.

Peacock will launch with a handful of originals, and all three scripted original series are, oddly enough, British-made. Users will also get early access to late-night shows and live sports.

The coronavirus pandemic has hit Peacock hard. Its centerpiece attraction for launch was supposed to be the Tokyo Olympics, which has been postponed, and the bulk of its original programming has been delayed until due to production shutdowns.

Rex Sep 23 '08 at Video telephony -- or video calls -- has been around since the s, but it was too cumbersome and expensive for the general public to use until very recently.

Improvements in video technology, as well as the wide availability of high-speed internet, have made video chat and video calls accessible and affordable for just about anybody.

Although it's not the only service available, Skype is one of the most popular video call services. You don't need a lot of equipment and the software is user-friendly, enabling you to make video calls within minutes of downloading it.

If the person you want to talk to also has Skype, it's free to use the service minus the cost of your Internet connection, of course. There is a fee if you're calling a regular landline or cell phoneand there's also a cost associated with some of the more advanced services.

In addition to video and voice calls, you can also hold teleconferences, instant message, share files of all kinds, text and make low-cost international calls using a special cell phone program called Skype to Go. This means that the program distributes the running workload across Skype users' computers via background processing, instead of running off a traditional server.

It's part of why Skype is so inexpensive. The company was founded in and operates out of Luxembourg. Up until recently, Skype was owned by an investment group that had eBay as its biggest holder; in Maythe company was acquired by Microsoft. InSkype had more than million users worldwide.

In reality, recycling can get pretty complex -- how it interacts with our environment, our politics, our economy and even our own human behavior patterns will play a major role in the future of our planet. In this article, we'll look at what recycling is, why and how it works and some criticisms of the practice.

What is Recycling? Recycling can take many forms. On a small scale, any time you find a new use for something old, you're recycling. One example is making old cereal boxes into magazine holders [source: All Free Crafts ].

At this level, used consumer goods are collected, converted back into raw materials and remade into new consumer products. It's rare for a recycled product to be exactly the same as the original material from which it was recycled.

Recycled paper, for example, contains ink residue and has shorter fibers than virgin paper paper made from wood pulp.

Because of this, it may be less desirable for some purposes, such as paper used in a copy machine. Eventually, goods move so far down the recycling stream it isn't feasible to recycle them any further. After being recycled a few times, paper is no longer usable. In some cases, goods can be up-cycled -- made into something more valuable than the original product.

How Landfills Work. Photo courtesy morgueFile.At its most basic, DNS is a directory of names that match with numbers. The numbers, in this case are IP addresses, which computers use to communicate with each other.

Most descriptions of DNS use the analogy of a phone book, which is fine for people over the age of 30 who know what a phone book is. Then multiply that contact list by everyone else on the planet.

In addition to creating a directory for all of these devices, words were used to let people connect to different sites; for most people, remembering words is easier than remembering specific sets of numbers. It is still possible to type in a specific IP address into a browser to reach a website.

Like the internet itself, the directory is distributed around the world, stored on domain name servers that all communicate with each other on a very regular basis to provide updates and redundancies.

With more than million domain names listed at the end ofa single directory would be very large indeed. Each named site can correspond to more than one IP address. In fact, some sites have hundreds or more IP addresses that correspond with a single domain name. For example, the server your computer reaches for www. Another reason for the distributed nature of the directory is the amount of time it would take for you to get a response when you were looking for a site if there was only one location for the directory, shared among the millions, probably billions, of people also looking for information at the same time.

Instead, DNS information is shared among many servers, but is also cached locally on client computers. Chances are that you use google. With so much caching going on, the number of queries that actually make it to DNS name servers is a lot lower than it would seem. DNS is organized in a hierarchy that helps keep things running quickly and smoothly. The initial request for the IP address is made to a recursive resolver, a server that is usually operated by an ISP or other third-party provider.

The recursive resolver knows which other DNS servers it needs to ask to resolve the name of a site networkworld. This search leads to a root server, which knows all the information about top-level domains, such as. Root servers are located all around the world, so the system usually directs you to the closest one geographically. Once the request reaches the correct root server, it goes to a top-level domain TLD name server, which stores the information for the second-level domain, the words used before you get to the.

The request then goes to the Domain Name Server, which holds the information about the site and its IP address. Once the IP address is discovered, it is sent back to the client, which can now use it to visit the website. All of this takes mere milliseconds. When the resolvers respond, the victim receives a flood of unrequested DNS data that overwhelms their machines.

DNS cache poisoning can divert users to malicious Web sites. Attackers manage to insert false address records into the DNS so when a potential victim requests an address resolution for one of the poisoned sites, the DNS responds with the IP address for a different site, one controlled by the attacker.

Once on these phony sites, victims may be tricked into giving up passwords or suffer malware downloads. DNS Security Extensions is an effort to make the communication among the various levels of servers involved in DNS lookups more secure.

ICANN became aware of weaknesses in the communication between the DNS top-level, second-level and third-level directory servers that could allow attackers to hijack lookups. That would allow the attackers to respond to requests for lookups to legitimate sites with the IP address for malicious sites. These sites could upload malware to users or carry out phishing and pharming attacks. This creates a chain of trust so that at each step in the lookup, the integrity of the request is validated.

The growth of big data and analytics also brings a greater need for DNS management. Keith Shaw is a former senior editor for Network World and an award-winning writer, editor and product reviewer who has written for many publications and websites around the world.
