The Simplest Of Things Can Spoil An Image
by: Florie Lyn Masarate
But using simple techniques combined with a bit of care, you can easily give you images the attention that will do them justice.
The materials used in printing your images play an important factor in the quality of the finished print.
1. Printer.
When buying a printer think about the materials that you use. If you are planning to print large format images, choose a printer that can handle rolls of photographic paper. These printers are usually more expensive, but great savings can be made when buying paper.
2. Paper.
Photographic paper comes in many different sizes and textures. No harm in testing out a few different papers from different manufacturers to see which one suits your needs best.
3. Ink.
It is strongly recommended to buy inks from your printer’s manufacturers. Third party inks may mean greater savings on your part but it does not guarantee that they will be suited for your printer.
It is advisable also to plan well in advance when you plan to buy a printer. If you are only going to print a small amount of images it may be better using a local photo lab.

Cisco CCNP Certification / BSCI Exam Tutorial: Troubleshooting Route Summarization
by: Chris Bryant, CCIE #12933
As you earn your CCNA and CCNP certification, you’re going to have to get comfortable with manually summarizing routes. This isn’t just another reason to learn binary math (although it’s a good one!), but summarizing routes is a true real-world skill that can help your network operate more efficiently. So the question isn’t just how to summarize routes, it’s why.
When you summarize routes in RIP, IGRP, EIGRP, or OSPF, you’re replacing a series of routes with a summary route and mask. With RIP, IGRP, and EIGRP, this actually lessens the size of the routing update packet itself - multiple routes are replaced with the summary route. For instance, the routes 8.0.0.0/8, 9.0.0.0/8, 10.0.0.0/8, and 11.0.0.0/8 can be summarized as 8.0.0.0 252.0.0.0. Only the summary address will be found in the update packet, making it concise yet complete.
Summarizing routes can also make the routing table smaller, yet still allow for complete IP connectivity when done correctly. Using the above example, the four more-specific routes will be replaced by a single summary route. Since the entire routing table is parsed before the routing process is complete, keeping the routing table as small as possible does help speed the routing process as a whole.
Linux Terminal Control Sequences

Linux Terminal Control Sequences
by: Sitecritic .Net
Linux terminals share alot in common with their primitive ancestors such as vt100 like consoles. These early devices is capable of sending sequences that signaled events outside of the normal flow of typed characters, such as escape, tab, linefeed…etc. Linux uses CTRL key to send out these out of band signals.
This article summarises many of the commonly used control sequences that are used in all Linux terminals.
CTRL-C
This is the most commonly used sequence. In the bash shell, CTRL-C will terminate any currently running process and return you to the bash prompt. For example, if you accidentally run a command that does not stop, use CTRL-C to cancel the command.
CTRL-D
Many Unix commands read their input directly from the keyboard. An example is the WC command. WC counts the number of lines, words and characters that a user types in from the keyboard. So if you tpye WC at the command prompt, the command will wait for your input till you use CTRL-D to signal the end of transmission.
CTRL-Z

Cisco CCNA / CCNP Exam Tutorial: Five Debugs You Must Know
by: Chris Bryant, CCIE #12933
To pass the BSCI exam and move one step closer to CCNP certification success, you’ve got to know how and when to use debug commands to troubleshoot and verify network operations. While you should never practice debug commands on a production network, it’s important to get some hands-on experience with them and not rely on “router simulators” and books to learn about them.
When it comes to RIP, “debug ip rip” is the primary debug to use. This debug will show you the contents of the routing update packets, and is vital in diagnosing RIP version mismatches and routing update authentication issues.
You know how to use the variance command to configure unequal-cost load-sharing with IGRP, but IGRP has no topology table that will give you the feasible successor metrics you need. With IGRP, you need to use the “debug ip igrp transactions” command to get these vital metrics.
Several factors are considered by OSPF-enabled routers when it comes to forming adjacencies, including hello and dead timer settings. If an adjacency doesn’t form when you think it should, run “debug ip ospf adj”. The reason the adjacency isn’t forming is usually seen quickly with this command’s output.

Advanced Link Checks
by: James Mahony
You should be able to find several indispensable facts about SEO in the following paragraphs. If there’s at least one fact you didn’t know before, imagine the difference it might make.
View the source of each and every page: is there JavaScript and CSS on the page? Remember that spiders may not index pages that have more than 10k or so of JavaScript or CSS embedded in them. Spiders don’t enjoy getting tangled up in JavaScript. So as a general rule you should avoid putting out prompts and alerts using JavaScript every time that a page loads. Because of this rule, it is also wise to avoid link partners who do so on the pages that they link to you from. If anything looks fishy, it probably is.

How Google Page Rank Works
by: James Mahony
Are you looking for some inside information on SEO? Here’s an up-to-date report from SEO experts who should know.
A ‘Page Rank’ is a number Google gives to a web page that represents how important Google thinks the page is on the web. When one page links to another, Google considers it to be effectively casting a vote for the other page. The more ‘votes’ there are for a page across the whole web, the more important that page must be. But that’s quite an assumption, isn’t it?
The importance of the page that is casting the vote determines how important the vote itself really is, meaning in Google calculations a page’s importance comes from the votes cast for it. These votes are then taken into account when the page is ranked.
As a general rule of thumb, Google Page Ranks along with Alexa ratings are the best indicators of how well your SEO work has been going. Granted, the ranking that you appear in on the results for your most important key words is the real indicator, but a strong Google Page Rank will help to boost this position substantially. The more links that you have pointing at your site, the better off you are. That’s a basic rule that will apply throughout your SEO operations.

A Guide to Information on Internet Phone or VOIP
by: Ted King
What you are about to read… will reveal to you what you should know about a new telephone communication technology called Internet Phone or Voice Over Internet Protocol (VoIP).
VoIP came about in 1995 when some computer programmers made voice connections between computers. Later that year, a software package was developed, and using the modem, speakers, microphone and sound card, one computer user was able to speak to another.
The process used involves converting the analog voice to digitized form. That involves breaking the voice down into steps that are then assigned numeric values. Then the data is compressed. After compression, the data is divided into packets that are transmitted over the Internet. Identifying information such as origin, destination, etc., are added that allows for reconstruction at the receiving end. At this point the packets are converted back to analog and the person on the other end of the line can hear the caller’s voice.
Online Billing: Save a Call

Online Billing: Save a Call
by: Jeff Downs
If you are looking to save money then look no further than electronic billing or online billing–sometimes referred to as EBPP. National averages per call received in a call center or by a customer service rep can be as much as $5.00. Reduce this by 50% and you save a significant sum of money. The question is how to reduce the number of calls flowing to your call center? The answer: short and sweet, electronic billing or online billing.
National statistics show that 60% of all calls to a call center are billing related. Questions such as, “Can you send me another copy of the bill?” “Why did my bill increase?” “I didn’t get my bill” can send your customer service reps over the edge; however, when you use an electronic bill or online bill solution you will save not only your customer service rep, but also you will save your customers the pain of having to call and ask. You can also use your call center personnel for other more pressing issues. Overall online billing saves you money.

6 Things To Consider Before When Getting A Photo Lab
by: George Williams
Digital cameras are so popular in recent years due to its convenience and capacity. Every event or celebration you go to now has at least several people snapping away. Once you pay for the camera and memory cards, your costs are zero, until you actually have a picture you want to print. You can take 40 pictures of your new child, niece, nephew, grandchild, etc, and if only two good shots came out of that, then you only pay for those two.
In fact, owning your own photo quality printer is definitely faster. There are even people who take a small printer with them and make prints for other guests right away. It is almost as easy as a traditional Polaroid camera. The large chains have jumped into this fray in a BIG way. Wal-Mart, Blacks, Business Depot, and many others. With all this competition comes low, low pricing. A typical 4×6 print from a big chain is cheaper than the retail cost of the do-it-yourself paper that the same chain sells in their photography center. And at home you still have to pay for the ink!

5 Biggest Mistakes Made By Business Owners Getting A Website
by: Ilya Pozin
It’s amazing how many business owners make each of the mistakes listed below. Making these mistakes could cost a company thousands of dollars initially, and take away from tens of thousands of potential dollars they should be earning monthly from their website.
1. Get their website done too early.
2. Pay way too much or too little for their website.
3. Focus on making it too pretty and flashy.
4. Do not get any traffic to their website.
5. Never make any money off their website.
The biggest mistake most businesses owners make is getting their website done too early. A smart business owner will first research their target audience in their specific Internet market, and only then build their website around their research.
A business owner needs to get training on how to find a target web audience in a specific niche market. They need to determine which keywords their website needs to be designed around, in order to bring in customers from search engines and other sources. A huge mistake made by business owners is they get their website formed around very broad keywords which have too much competition.
