Hello and welcome to another How-To post. For this post I will uncover the mysterious convoluted PageRank system Google has put in place in order to properly grade ranked results for a specific keyword(s) and list them accordingly. I say this system is mysterious because Google does not enjoy revealing the intricacies behind the calculations of this complex enigma but the monster company does explain things you can do to predictably influence your websites’ ranking on the organic search results page. First however let’s look at what Mr. Ian Rogers has to say on the PageRank.
This gentleman had many interesting guesses as to how one could possibly calculate the PagerRank of their respective website. He takes into consideration other authors’ ideas and obviously incorporates the equation Google showcased once but never again. Please check out his website. Not only do his calculations make sense, he provides many useful links at the bottom of his site such as the first paper on PageRanks published by Google co-founders: Sergey Brin & Lawrence Page. And a neat PageRank Calculator for those of you interested in a machine doing most of the work for you. So here are some points Mr. Rogers makes on pagerank.
Google toolbars show the pagerank rating of a webpage by logs of 10 (i.e. toolbar pagerank= 0, REAL pagerank= 0-10, toolbar pagerank= 1, REAL pagerank= 10-100, etc.)
Ian states Google re-indexes the pagerank of all webpages online every month AND changes the pagerank scale as well making it difficult to accurately gauge the exact pagerank number your webpage currently has, therefore any PR (pagerank) numbers you receive from toolbars or PR checkers are essentially really good guesses not necessarily definitive PR’s.
Mr. Rogers makes a very simple definition for pagerank he states: “In short PageRank is a “vote”, by all the other pages on the Web, about how important a page is. A link to a page counts as a vote of support. If there’s no link there’s no support (but it’s only an abstention from voting rather than a vote against the page). ” I really like this definition. It is very simple to remember.
Another problem in calculating PR of websites is that in order to use the algorithm provided by Google in the original PageRank paper developed by Google founders (Sergey Brin & Lawrence Page), you need to know the PR of the pages linking into your webpage. Then you can’t find out those PRs until you find the PRs of the websites linking to THEM and so on. However that same paper also provides us with the algorithm necessary to duplicate the normalized link matrix of the web and therefore allows us to check our PR without knowing anyone else’s PR!
PR(A)= (1-d) +d (PR(B)/1), PR(B)=(1-d) +d (PR(A)/1), d=0.85. So this is the equation (according to Mr. Roger) one can use continuously to more accurately find the PageRank of his/her respective site. In other words, Page A(PR(A)) links to Page B(PR(B)) and vice-versa and d shows the damping factor for the answer you get. Therefore, assume your webpage is Page A and an inbound link to your site is Page B. Then just plug all the numbers repeating the process using the answer for PR(B) as the PR(B) value in the 2nd run through.
Ian later explains how the arrangement and order of each calculation matters when calculating PageRank. This makes sense because PageRank depends on the quality of inbound links on your site which are essentially “voting” for your page and their respective PageRanks as well. When trying the equation keep in mind the base value for the average PageRank is 1.
With the above equation any page that is online will start off with .15 of a PR or “voting power however, Mr. Roger warns Google supposedly has a post-spidering phase back at their lair which automatically deletes any pages without inbound links! Scary….
Mr. Rogers then illustrates how external sites that your site links to do not help raise your PageRank up by much if they themselves are not inbound links on YOUR website. The value for the owner homepage went from: PR(A)= .92 to: PR(A)= 3.35! That is quite an impressive increase.
Mr. Rogers goes on to give various examples of really interesting ways to structure your website in order to manually focus traffic to the main homepage, or whichever page you want to focus on for that matter. He also explains a couple strategies one can use to greatly improve their PageRank.
Tip #1:Be a Mega-Site. Sites such as Fox News, which has a PR of 8 by the way, have such large amounts of articles contributed by many authors on a weekly basis and so many inbound links from these pages going back to their homepages they conquer the rankings because of the amount of quality content they have at their disposal.
Tip #2:Give Away Something Useful.phpBB was a company that developed a bulletin board system they gave out for free to any interested websites over the internet and basically became so popular it raised their PageRank to an 8/10! (Currently it’s at a 5/10 but that just shows nothing lasts forever!).
Tip #3: Stick with One Page When Raising the PR. Essentially the co-founders of Google stated in their paper that the average PageRank (at the time) is 1.00. Therefore instead of fighting a battle of averages for every page focus on raising the rank of one page in particular (homepage, request quote page etc.). This will concentrate your efforts on one page maximizing their effects and bringing up your site first in the rankings more quickly!
I hope this post was informative as it was interesting (at least to me!). Again these calculations are not certified by Google. But they do give very interesting glimpses into how this ranking system seems to operate. Google does state the equation is ever changing and the equation most people use to figure all this out might not even be used anymore. But interesting to know nonetheless!
Today I really wanted to explore the hurricane category classification system and how it became the warning system that we use today. I really feel its interesting to see how the current scale describes and sizes up these hurricanes especially with Hurricane Irene still attacking the East Coast. Hurricanes have always been forces of destruction terrorizing coastal areas such as the Caribbean and parts of the coastal U.S. But it wasn’t until two scientists, Herb Saffir and Robert Simpson, decided that the old building codes structural engineers were using for determining the resistance of structures to wind related factors was out of date. Shockingly these building codes were unchanged since 1926! Basically costing the United States a lot of money just for not upgrading the codes. So they teamed up and designed this super effective and accurate category system that sums up hurricanes accordingly. Click here for info on the classification system.
The 5 Category System
Category One: Very dangerous winds will produce some damage. This category includes winds that are anywhere from 74 to 95 m.p.h. Category one hurricanes have the ability to kill and maim animals and/or people.Not only can they kill your favorite pet, these hurricanes can completely destroy your mobile home or any building built before 1994!. Even swimming pools might suffer heavy casualties as this heavy hitting hurricane rips across your hometown.
Category Two: Extremely dangerous winds will cause extensive damage. So what’s worse than a category one hurricane? A category two. These bad boys traverse the coast at about 96-110 m.p.h.! That is a semi slow Lamborghini Gallardo! These hurricanes tend to kill slightly more people and animals but it probably isn’t as bad as a category three. Mobile homes are also much more likely to be uprooted and destroyed by these barbaric hurricanes (Can there really be civilized ones?) but post-1994 constructed homes can also be severely damaged in these disasters. Surprisingly during category two hurricanes is when filtration systems for viable water sources begin failing. Essentially in a category two much more things are being thrown around.
Category Three: Devastating damage will occur. This is where hurricanes really start making stronger negative impacts on livelihoods. With these hurricanes the average wind speed will be 111-130 m.p.h. That is mind boggling. Many people and animals will now be at high risk of death just from being within the hurricane. Newer homes might not be completely decimated but most likely will have roof and wall collapses. Even well constructed homes are going to suffer extensive destruction if they are still standing. Both electricity and water sources will be unusable for a number of weeks after this deadly type of hurricane passes.
Category Four: Catastrophic damage will occur. Speeds at this level of hurricane ferocity will hit averages of 131-155 m.p.h. These forces of nature will basically do what category threes do except on a category four scale. In other words apartment buildings will most likely have their rooftops ripped off and weeks after this hurricane passes broken glass and shattered windows will still pose threats to passerby and survivors of this calamity. Additionally, many trees are going to be completely uprooted and block off sections of the residential areas they use to line with their beauty along with destroyed telephone poles. Most of the affected area will be uninhabitable for months!!!
Category Five: Catastrophic damage will occur. Basically category four and five hurricanes are very similar in their potential destructive power with the only difference being category fives are a bit more destructive since the rate of speed for these hurricanes need to be at an average higher than 155 m.p.h. This hurricane is what nightmares are made of. Regardless of being in your house or in a skyscraper, your chances of death are always high. This is because of the sheer force of moving debris and the speed of the winds themselves. Pretty much every mobile or bolted down building will be annihilated with the exception of a few apartment buildings. The area would be inhospitable for months.
I hope this descriptive listing of hurricane warnings has enlightened you and opened your eyes to just how devastating a hurricane can really be. I really never knew how the government scaled hurricanes and on what basis they determined the category levels but after researching them for this post they have my respect that’s for sure. Hopefully Hurricane Irene starts dying down so we don’t see anything close to a category 3-5. Currently I believe it is a Category 2. For more information click here.
Hi everyone welcome to the Void of interesting Things! I have been pondering a question all of this past weekend that should be pretty self explanatory (especially for me since I do work at an electronics recycling center) but isn’t. Basically I really wanted to know what makes e-waste such an international threat. obviously it’s a problem in developed countries with a lot of technology and pollution because of all these urban areas we have but why would the e-waste problem be just as bad or worse in countries located in Africa for example, where they have cities that aren’t as big as ours and don’t have most of the technology we do? It would make sense to me that those areas would not be so affected by e-waste but it’s actually the opposite. Click here for more info.
It turns out the first world has been using the third world as its international landfill for quite some time. I’m assuming the idea behind this was to get the trash far enough away from us so that we wouldn’t get hurt by it. Well the problem with this is that many of the materials present in common products that make up the e-waste we have been dumping into third world countries (i.e. cathode ray tubes in monitors, mercury lamps in LCDs) are poisonous to the environment AND basically get dumped back into the ocean by the residents of the countries we use as landfills. The article added above sums this up very clearly.
Essentially this is the problem and I feel it probably won’t stop because it has become a sustainable business that is profitable. The only way to really impede this momentum of ruin that we have propagated might be to spark a trend to increase the lifespan of our technological products. This website called www.ElectronicsTakeBack.com (quickly becoming a fave website of mine!), explains how companies tactically plan out how long they want your cell phone or computer to last see here. The list they have is really insane to see such common occurrences with electronic issues being summed up as a planned deficiency by the hardware manufacturer or cell phone distributor. But it makes a lot of sense. Working in an electronics recycling center I see anywhere from 50 to thousands of dead cell phones come in daily or weekly. That is the same for computer parts that aren’t even necessarily broken just one year, two years old. I think supporting the Electronics Take Back Coalition or at least having the presence of mind to wonder to yourself “I wonder why I have a drawer full of functional cell phones in my house?” will go a long way in moving towards the right step to make this world a better place. Thanks for stopping by my blog to read my rants! Over and out.

A shocking surprise statement was made yesterday from top Apple CEO Steve Jobs regarding his retirement from his CEO position. Statement excerpt: “..[I] always said if there ever came a day when I could no longer meet my duties and expectations as Apple’s CEO, I would be the first to let you know.” For more info on this article click here. Unfortunately, that day has come. This development marks the end of the career of a man that has arguably redefined Apple as a fighting contender to Windows operating systems with commercials such as the “Are You a PC or Mac?” campaigns and products like the iMac. Mr. Jobs has recently recovered from pancreatic cancer which has prevented him from showing up at various recent Apple presentations. He has been on medical leave since January 2011 and has been elected to continue acting as chairman of the board at Apple but is sadly resigning the CEO position to former COO, Tim Cook. Article info: click here.
What This Means for Apple.
In Apple’s most recent Q3 period earning statement it has broken its own record by raking in $28.57 billion in revenue. Apple sold 20.24 million iPhones and 9.25 million iPads. Both were products innovated and introduced into the market by Steve Jobs. Article info: click here. On Thursday Apple stock fell about 1% due to the retirement announcement. In addition to affecting these financial numbers in the future, the resignation of Steve Jobs is being foreseen to affect the feel of future product introductions from Apple. According to PCMag.com contributing writer, Sara Yin, Jobs has been responsible for giving Apple a charismatic, confident face in the presentations of its newest product lines. She continues to outline several downright hilarious and noteworthy moments in Steve Jobs career that show just how difficult it is going to be to fill the recent CEO’s shoes.

Hello, hopefully today is a bright and beautiful day for you full of UV ray soaking action!. Or if you’re by chance trapped in a cubicle (like myself) then I hope you have had a chance to step outside for a stretch or a walk according to this other list article, it is healthy for you! (Hurry before you get abducted.) So I love the idea of intelligent extraterrestrial civilizations scattered among the universe. I think the innate human desire to not want to be alone is what gravitates people to pondering this idea. Compounded by the fact that we, as a species, do not consider any animals on Earth as our equals makes this notion all the more widespread among the populous (In my opinion). I really felt these articles were insightful on the speculation of the effects other sentient beings would have on us and our planet: Aliens Might Save Earth? & Aliens Could Attack Earth to End Global Warming, NASA Scientist Frets. They are both covering the recent Penn State/NASA Study. *** If you really want the full scientific breakdown for every scenario here is the full report!.
5 Reason Countdown
1.Destroy us to liberate the terrestrial and intergalactic ecosystem. According to one scenario from the study Extraterrestrials could outright destroy us because of how damage our polluted Earth will cause to other planets in the solar system. Elevated greenhouse gas emissions (from the expanding of the human civilization) are changing the spectral signature of Earth which is detectable from space. I never knew pollution could be THAT bad.
2.Selfishness of wanting the universe all to themselves. This scenario actually made me smirk. It is funny to think you can manipulate gravity to the point of stopping your craft in mid flight to reverse direction or fly up from the atmosphere to space and still not have the common decency to share!.
3. They want to eat our brains. Another scenario pondered in the project was aliens would come to Earth because of their desire to breed and feed on us like we feed on cattle.
4. They need more “lab humans”. In much the same way our scientist use animals to test chemicals and products that might otherwise be harmful to humans, aliens might come to Earth to take people in order to test out their newest ray gun technology. Ouch.
5. (Personal Favorite) To enslave the whole human race. Extraterrestrial intelligence might come land on Earth to collect our species for intergalactic construction projects. I like this one because it would give us an incentive to finally work together. Maybe they’ll offer great retirement benefits.
Hope you enjoyed this brief synopsis on alien invasions on Earth!
About one month ago (June 28th, 2011 to be exact) the Supreme Court decided to overturn the law passed by the Governator, I doubt he will be back, Rep. Arnold Schwarzenegger. The law prohibited minors from purchasing video games across the state and got many people upset especially the ESA (Entertainment Software Association). Personally, being an avid gamer myself I feel it should be up to the parents to decide whether or not Batman: Arkham Asylum is appropriate for their children not the government. But I guess that’s one man’s opinion. What’s yours?

This question really bothered me after watching a History Channel documentary on plastic pollution and how drastic of a negative impact it has been having because of marine life thinking it’s food. I am not a “tree hugger”. However ever since getting a dog (Akita/German Shepard Mix; very smart/fun puppy) I have inexplicably gotten more attached to the natural environment. The U.S. Census Bureau has a population clock stating the U.S. & World Population at this very moment. Right now, 2:23 p.m. Pacific Standard Time, the world population is at 6,957,210,733 people.

But back to the issue. 83% of the Earth. That’s an unbelievable amount of land. This statistic is from an article on National Geographic’s website, you can see it here. It is very old, 2002, which makes this even more shocking. The article goes on to give more statistics just to wrap your head around the 83%: In Ghana, 98% of discrepancies in extinction numbers over a 30 year period were attributed to the national park’s size and the people affecting it’s ecosystem within 30 miles of it. Ghana is nowhere near as advanced as more privileged countries: the E.U. or the U.S. Yet this footprint shows a reach extended by the technology advancing our civilization from the more advanced countries on Earth. This reach is both direct and indirect. Obviously pollution is an indirect factor and hunting down rare exotic animals is a direct one. But being 83% influential can be a positive thing too. Why don’t we move our weight around to dominate this planet in a good way? (possibly increasing our dominion for a little while longer in the process) It would not hurt to prevent one extra piece of plastic from going into the public drainage system and ending up choking “Nemo” (clown fish) to death because he thought it was delicious food. It’s just something to think about. Hope you don’t feel too bad after all we are only human.
