Consumer electronics like personal digital assistants are designed to perform tasks that are identical to tasks performed by larger devices but are used more because they are portable and can be enjoyed in many settings where the larger device will seem inconvenient. Many people will own personal computers and use the connectivity devices to download music to the handheld consumer electronics such as MP3 players and PDA's, but they will enjoy the storage space found on the computer and store musical files until they are needed.
A person has the option of installing global positioning devices into the dash of their automobile or using these consumer electronics from portable devices such as PDA's. Some computer software programs will serve the same purpose and a person will find that they can use the internet search engines to find websites that will perform exact distance calculations from one place to another. All of these consumer electronics will perform the same task but consumers are given a choice in which one they want to use and most users will consider the cost of using each method.
Some people use consumer electronics to help with mathematical calculations. A handheld calculator is very useful to a budget conscious shopper, but will prove to be an invaluable tool for someone who is performing intricate equations for algebra. Some users will need consumer electronics while at work because buying materials for a job site will require a building contractor to know the square root measurements of all building surfaces.
Computer software can be used to calculate the cost of every home remodeling project and consumer electronics like flash sticks can be used to store the files safely until they are needed. Computer technicians can use these devices to store many files that are needed for completing compute repairs, and other consumer electronics can be used to verify if electrical connections are energized or not safe to work on.
Other consumer electronics will make tasks simpler and reduce the cost of building projects. Electronic devices such as stud finders allow building contractors to find objects behind drywall that are not visible with the naked eye. A contractor might need consumer electronics such as heaters to make paint dry faster. When the building is finished, the occupant will rely on other electronic devices to maintain a comfortable temperature throughout the building.
While the design of consumer electronics is angled toward accomplishing a specific purpose, many devices can be used to accomplish a variety of tasks. Electronics are meant to simplify life and serve as forms of entertainment outside the home. Radios are one of the consumer electronics that can provide safety information if it is tuned to the right channel, or it can help keep drivers awake while driving for hours on a busy highway. Some consumer electronics are capable of putting drivers in contact with fire, police or ambulance companies in the event that an accident occurs on the roadways.

Cool Designs In Consumer Electronics
Learn About Furnace Torches, Gas Torches, And Soldering Torches
This is perhaps one of the greatest parts of the entire metal casting process like seeing what was once just sketches solidify from liquid iron, or whatever metal is used. All the metal caster needs is an idea and red hot liquid metal.The furnace is the pride and joy for the metal caster.
Most will construct their own furnace tweaking the design here and there to better suit their needs. Many home foundries are based on home made furnaces and if constructed correctly can prove to be highly effective. The crucial part of the furnace is the furnace torch. The torch brings the heat, incredibly high heat, and without it that chunk of metal would just sit in the crucible and never see life as something new and exciting. Except as a paper weight; a very ugly paper weight.When searching for an appropriate casting torch the hobbyist will need to take several things into consideration. The size of the furnace, and what metals you plan to use are chief among the considerations. Many casters will use a torch that uses propane gas as it provides enough pressure and heat to melt most metals. If the hobbyist plans to use natural gas like the kind that is provide in households they may find that the pressure is just not enough and the desired temperatures will not be reached. The same is true for Butane. While natural gas and Butane can be used, propane seems to yield the best results. Oxyacetylene torches are a favorite with many casters especially for casting iron.Price is yet another consideration. While it may be possible to rig a casting furnace it is not always advisable. Torches can range in price from $40 to several hundreds of dollars depending upon the size, the use, and accessories.Many jewelers are able to use small independent casting torches but when dealing with metal casting in furnaces you will need to use a torch that can be mounted and used in such a fashion. Many think that just because you need a furnace torch you are going to need a large furnace. This is simply not true.
A small furnace and furnace torch can produce enough heat to melt aluminum, iron, and a number of other metals. One of the furnaces functions is to help the flame reach optimum temperature and in the case of Reverberatory Furnaces, a furnace torch is an absolute requirement.Casting torches can be found in some hobby shops and in hardware stores. Several online shops also sell torches for the hobby metal caster. When buying a torch hobbyist should shop around in order to find the best deal. Always use caution when dealing with a furnace torch.
XML Within the Enterprise
The last four decades of the twentieth century witnessed the birth of the Computer Age. Computers have become an essential tool for nearly every corporate worker. Personal computers are now found in over 50 percent of U.S. households, and with this proliferation has come the explosion of the Internet. The Internet has not only changed the way consumers gather information and make their purchases, but it has also completely changed the way corporations must do business.
Today corporations must be able to respond quickly to market pressures and must be able to analyze large quantities of data to make appropriate decisions. To be of any use to the corporation, this data must be accurate, relevant, and available immediately. As we will see in this tutorial, a Digital Nervous System (DNS) will provide the corporation with a computer and software infrastructure that will provide accurate, relevant data in a timely manner. One of the most important elements of the DNS is the movement of data. In many circumstances, the ideal way to move this data will be in Extensible Markup Language (XML) format.
XML can be used to create text documents that contain data in a structured format. In addition to the data, you can include a detailed set of rules that define the structure of the data. The author of the XML document defines these rules. For example, you could create a set of rules that can be used for validating Microsoft Exchange email documents, Microsoft SQL Server databases, Microsoft Word documents, or any type of data that exists within the corporation.
An industry initiative called BizTalk, which was started by Microsoft and supported by many other organizations such as CommerceOne and Boeing, provides a standard set of rules that are agreed upon by different corporate communities and individual corporations. These rules are stored in a central repository and can be used to build standardized XML messages that can be sent between applications within the corporation and to applications belonging to the corporation's partners. Both large and small corporations can benefit from using these XML messages because it allows them to do business with a wider range of partners.
XML can do a great deal more than just move data. Data can be included in an XML document and then an Extensible Stylesheet Language (XSL) page can be used with the XML document to present the data in Microsoft Internet Explorer 5 (and hopefully other Web browsers in the near future). Using an XML document and an XSL page allows Web developers to separate data and presentation. tutorial 2 will examine why this technique is essential for corporate Web development.
Another initiative, the Simple Object Access Protocol (SOAP), enables you to use XML to call methods on a remote computer on the Internet, even through a firewall. The SOAP initiative is being developed by Developmentor, Microsoft, and others. For more information on SOAP, visit http://www.develop.com/soap/.
BizTalk, Internet Explorer 5, and SOAP address three of the most important issues facing corporations today:
Creating standardized messages that can be moved inside and outside the corporation (BizTalk)
Separating data and presentation when building Web pages (Internet Explorer 5)
Calling methods through firewalls and between different platforms (SOAP)
The focus of this book will be on the features of XML and how it can be used to address these three issues.
Gather Your Keywords to Improve Search Engine Positioning
We all do this - when we need to look something up on the Internet, we automatically fire up our favorite search engine. For many web surfers, their home page is already set to Google, Yahoo, or MSN. In that search engine we punch in a few words that relate to the information we need. Almost immediately we are overwhelmed with a batch of results. But how much of these results do we actually read through? The majority of web surfers scan through the first page or two, and perhaps even through page three. If a web site is positioned beyond page three they are basically out of luck. When web surfers punch in keywords related to your products and services, does your site come up within the first few pages of the search results? If it does, you're likely running a very successful business in which visitors come to you without much need to advertise.
Most web site owners haven't built their website with reaching search engine users as one of the site's goals. In this article I will pretend that you own a shopping web site called PrettyDresses.com. Your web site is very lovely, full of pictures of dresses in all the latest styles and trends. Anyone who has found your site is very impressed with the selection of products and beautiful pictures. But you ask yourself, why is your traffic so low? Why isn't anybody finding my site? What can I do? The answer is quite clear and the problem is quite easy to solve.
Almost without thinking, web surfers (more specifically web searchers) will pop open their search engine and type in something like 'evening gown'. As this is their first thought, it should also be yours. Does your web site contain the words and phrases that web searchers are using to find your products and services? Are those words found on your website many, many times, only a few times, or not at all?
On regular intervals search engines crawl the web, reading and collecting information on the sites they come across. As they come across your website, they look for what the most frequently used words are phrases are to determine just what it is that your web site is all about. The better your web site does at effectively using the phrases that are being searched, the higher up the list your web site will be displayed on web searches. If your web site's content does not match what is being searched, it will not be found. It is a simple as that.
It should be clear by now that you should be starting to put together a list of keyword phrases to include within your web site. This list should include your products and services and any related items. There are many people searching for dresses as you are reading these words. Do they all use the exactly same phrases - of course not. Your mission is to discover as many of these phrases as possible and which phrases or words are used most frequently. The list should be prioritized based on which words are used in searches most frequently.
Brainstorm. Sit and think about what your web site is really all about. Close your eyes and picture your website as a store with customers looking around. What are they looking for? What are they asking you for? "Excuse me, I'm looking for a...”
Think about which words relate to your products and services. What is another name for dress - a gown, evening gown, sun-dress, a cute black dress, etc.
Be sure to ask family and friends, and clients and associates. Which phrases or words might they use when looking for your products and services? You are soon to discover a pattern. The most commonly used search terms will start to emerge.
Which keywords do high end competing web sites use, that carry products and services that are similar to yours? Their research may save you some of your own.
Pretend to be different types of customers. Be a customer that knows exactly what they want and jot that down. Also be the customer that is just looking around, or looking for ideas. This second customer may use more generic terms, while the first customer may refer to specific items. What other types of shoppers can you pretend to be? What about a wealthy shopper versus a bargain hunter?
Are some of the words on your list often misspelled? If so make sure to jot down the incorrect spelling as well. Poor spellers also have money to spend.
Are your products or services focused on a specific geographical location? If so, be sure to jot down the neighborhood, quadrant, city, state, and even country. A visitor may not want to drive too far from home and may therefore search for 'dresses in south Dallas'.
Also be sure to include the different variations of your selected keywords - for example: dress and dresses.
Remember to keep a balance between keeping your pages readable by both visitors and search engines. An over-optimized page will include many, many keywords which will improve your positioning with search engines, but may sound like nonsense and unprofessional to a real human visitor. Don’t turn away potential customers after they’ve found you. Some search engines have been known to punish web sites that attempt to trick the system with keyword spamming on their web pages.
Now its time to get to work. Use these ideas in this article to optimize your web site's content. Be sure to include the words and phrases that your potential visitors have in mind. Don't forget about your web site's title and description meta tags, which are only read by search engines. With some hard work and careful analysis you'll be sure to see a lot more traffic in your future.
Bad SEOs? What about Bad SEO Clients?
As an SEO, I can see things from the other side of the table. You see, despite trying hard to make it clear I'm a good, ethical, results-oriented, smarter marketing, white-hat SEO, I have gotten no end of inquiries from bad prospective SEO clients. Sure, no one who gets cheated is ever entirely to blame, and some cheated businesses are entirely blameless. But the bad SEOs would have too small a market to stay in business if it weren't for almost-as-bad clients.
Shades of Bad SEO Clients
First, let me make clear what I mean by "bad" SEOs. Bad SEOs are bad because they either do unethical things to get e-marketing results, or because they consistently fail to deliver results. A good SEO delivers results and does it without trampling over other people's rights (like submitting automated comments to their websites or trying to get good sites de-indexed).
A bad SEO client, in turn, is someone who will only be satisfied (albeit temporarily) with a bad SEO. Because they refuse to consider ethical web consultants or smarter marketing strategies, they are creating markets for the e-marketing charlatans and black-hats. There are two basic types of bad SEO clients: crooks and fool--oops, I mean, ethically challenged and judgmentally-challenged.
Ethically-Challenged SEO Clients
I haven't gotten so many inquiries asking for out-and-out unethical services. Still, I've been asked about blog-sp@mming software and other shady internet marketing tactics a couple times. A colleague shared this gem with me: "Have you thought about just scanning a book from the library and using it for web content? Or is that too high-risk?" (Seriously, someone asked him this.)
Of course, judging from the amount of comment sp@m and SEO-motivated hacking on the web, there is plenty of demand for this stuff.
Judgmentally-Challenged SEO Clients
A much larger group of bad SEO clients are simply those who insist on putting themselves in the way of fraud. Yes, that's right: I'm blaming the victim. Someone who goes looking for a $5 gold watch can't cry too long if the watch turns out to be fake or hot. With SEO, there are a few more nuances, but it's the same essential idea.
The overwhelming majority of these judgmentally challenged souls are private individuals whose only business is the business-in-a-kit variety. Yet they are also sometimes representatives of actual successful companies. The real businesspeople tend to be quicker to let their misconceptions go (after all, they can afford the real SEO alternatives), but not always. Let's look at some representative types of this group, straight out of my own inbox (note: these are inquiries from prospects, not actual clients).
1. Something-for-(Little More than)-Nothing Clients
Really, I tend to think these people should be in the ethically challenged group, but maybe that's just the remnant of my work ethic making me be mean There are actually two kinds of these clients:
- The ambitious but cheap client: "I'd like to get to the top of Google for the keyword, 'mortgage' so I can turn over $100,000/month in revenue. I can spend up to $1,000."
-The Adsense-is-my-business-plan client: you wouldn't believe the numbers of inquiries I get from people who only plan to make money off Adsense or other on-site advertising?they don't even have a plan for getting repeat traffic, nor do they have content to synergize with the SEO effort. By buying promotional services, they would essentially be buying advertising in order to make money off advertising?you see where that could be a problem?
Another way of looking at it: why wouldn't I just create a site myself and keep all the profit from my efforts? In fact, most SEOs do have their own project sites, which are often monetized by Adsense. The money we could otherwise get from Adsense is one very low baseline for pricing our services. Legitimate SEO clients are typically selling goods or services at a profit rate that works out to ten or more times what they could get from Adsense.
In addition to the greedy, I also see a few other kinds of less common, but still problematic prospective SEO clients:
2.SEO-Starry-Eyed Clients: "Search engine traffic is definitely the best way for me to get pet-sitting clients in my tiny Himalayan village."
3.The Little-Knowledge-Is-a-Dangerous-Thing Client: "Don't tell me about keyword research, content, anchor text, or natural linking strategy, just get me the PageRank (or links, keyword density, or whatever the fad is)."
4.Gullible-and-Not-Letting-Go Client: "I know of at least two services that will submit my site to thousands of search engines for $29.95. If you can't do that, I'll take my business elsewhere."
5.I-Will-Never-Trust-SEO-But-I'll-Consider-It-Anyway Client: "No one can guarantee a good search engine ranking so this is all pointless?I'll just go with that $29.95 search engine submission package someone just emailed me about. At least it's cheap."
In short, if you are going to find good SEO web consultants, you need: 1) realistic expectations; 2) a realistic budget; 3) solid information. Don't expect something for nothing, do a little reading, and it's much less likely you'll fall victim to bad SEOs.
10 Things We Hate About Apple
Narasu Rebbapragada and Alan Stafford, PC World
The company formerly known as Apple Computer and now called simply Apple, Inc. is unique in many ways--including in its ability to drive even folks who admire it positively batty. It makes great products (usually), yet its secretiveness about them borders on paranoia, and its adoring fans can be incredibly irritating. Of course, its fans have to put up with some irritations, too: Simply being a member of the club still means you must endure unending jabs from the other side of the socio-political-techno aisle. But do they have to wear their suffering as a badge of honor?
Today, we--that's us, Narasu and Alan, veteran Mac users both--are going to get some stuff off our chests. We've enumerated ten things we hate about Apple (or its followers, or simply about the experience of using its products). But in the interest of fair play (not to be confused with FairPlay, Apple's DRM technology) we're also publishing another list--Ten Things We Love About Apple.
Use the Comment link at the end of this article to add your own gripes about Apple--or to defend it.
And so, with protective helmets in place, off we go:
1: Free Speech, Anyone?
Even if you're no Apple fan, this particular issue might not rise to the top of your own personal gripe list--but hey, we're journalists. So sue us.
Er, that's probably not the right turn of phrase to use, considering that in December 2004, Apple filed a lawsuit against the AppleInsider, O'Grady's PowerPage, and Think Secret Web sites for posting information about upcoming technologies that Apple had shared with outsiders under nondisclosure agreements. In the case of O'Grady, the news was of a FireWire interface for GarageBand. In the words of O'Grady himself: "yawn."
Apple pressured the sites to reveal their sources, and even worse, pressured the sites' ISPs. In May 2006, a California court said no way, ruling that online journalists enjoy the same First Amendment rights as "legitimate" offline journalists. Seems silly in today's world, doesn't it? Recently, the court ordered Apple to pay the sites' legal fees--about $700,000.
2. More Secretive Than Homeland Security
Those feds are secretive, but they're no match for Apple reps' infuriating stock answer: "We don't comment on future product plans." Being an Apple adherent means never knowing for sure if the shiny new MacBook or iPod you just bought is about to be rendered obsolete by a Steve Jobs keynote.
Of course, Apple is merely the most famous secretive Silicon Valley company, not the only hush-mouthed one. And tight lips make for explosive buzz when the company does decide to drop a bombshell. But contrast Apple's secrecy with Microsoft's lack thereof--Bill Gates, Steve Ballmer, and company love to talk about their company's upcoming products, and they still get their fair share of buzz. Even though many of those plans have a tendency to not actually come true.
3. Ain't Too Proud to Blame
When Apple shipped iPods containing a worm last year, instead of issuing a humble mea culpa, Apple took a swipe at Microsoft, saying, "As you might imagine, we are upset at Windows for not being more hardy against such viruses, and even more upset with ourselves for not catching it." As you can imagine, that didn't fly with security experts. How about an apology to the folks who were unlucky enough to buy the infected iPods, period?
4. iHate iAnything
Apple first floated the idea of product names with a leading lowercase letter in 1994 with eWorld, an ill-conceived online service that went belly-up after a year and a half. But when it introduced the original iMac in 1998, it hit on a phenomenal success--and prompted hundreds of third-party manufacturers to follow with sickeningly cute Bondi Blue products with names that also began with a lowercase "i." Now dozens of Apple and third-party product names begins with "i." Their manufacturers are all jumping on the bandwagon, hoping that a single letter will sway us to buy their stuff. Meanwhile, you can't even start sentences with the products' names.
Is it any wonder that we're inclined to like Apple TV in part because it turned out not to be iTV? Or that we're kind of sorry that Apple was able to strike a deal with Cisco to share the name iPhone?
Principal Guilty in Microsoft Piracy Case
The trial of Alexander Ponosov, who was charged with violating intellectual property rights by using classroom computers with pirated versions of the Windows operating system and Microsoft Office software installed, has attracted wide attention.
Russian officials frequently allege that foreign governments, including the U.S., are meddling in Russia's internal affairs, and Russian media reports have portrayed the case as that of a Western corporation bringing its power to bear on one man -- in this case, a principal who also teaches history and earns $360 a month.
Microsoft, however, has said repeatedly it has nothing to do with the charges, which were brought by Russian prosecutors in the Ural Mountains region where Ponosov's school is located.
The case "was initiated by Russian authorities under Russian law," the company said in an e-mailed statement after the verdict. "Microsoft neither initiated nor has any plans to bring any action against Mr. Ponosov."
Prosecutor Natalya Kurdoyakova said in televised remarks that Ponosov knew he was violating the law "and illegally used these programs in computer classes."
Ponosov has maintained his innocence, saying that the computers at the school came with the software already installed.
"I had no idea it wasn't licensed," Ponosov told The Associated Press by telephone. He said that he planned to file an appeal.
"Prosecutors made a lot of mistakes starting from the moment they checked the computers," he said.
Ponosov was found guilty of causing $10,000 in damage to the company, RIA-Novosti quoted judge Valentina Tiunova as saying.
In February, the court in the Vereshchaginsky district of the Perm region threw out the case, saying Ponosov's actions were "insignificant" and presented no danger to society. Both Ponosov and prosecutors vowed to appeal in hopes of forcing a clear decision, with Ponosov saying he wanted a full acquittal.
In March, the regional court ordered Ponosov to stand trial a second time.
Despite government pledges to crack down on Russia's rampant piracy, the country remains the No. 2 producer of bootlegged software, movies and music after China.
In April, the Bush administration put Russia, China and 10 other nations on a "priority watch list," which will subject them to extra scrutiny and could eventually lead to economic sanctions if the administration decides to bring trade cases before the World Trade Organization.
The designation was made in an annual report the administration is required to provide to Congress each year that highlights the problems U.S. companies are facing around the world with copyright piracy. The report said that the United States will be closely watching to see how Russia fulfills the commitments it made to upgrading copyright protection as part of a U.S.-Russia accord reached last year which was seen as a key milestone in Russian efforts to join the WTO.
