Caffeine might just affect SEO

With so much emphasis on search engine optimization (SEO) in recent years, companies have worked hard to get their keywords to rank high in SERPs, but will all that be for naught if Google adds “Caffeine?”

On their company blog, Mike Dobbs and Martha Mukangara of 360i write that a change to Google’s Caffeine would “substantially” affect search rankings for keywords.

By comparing 40 retail keywords in Google “Decaf” versus the beta version of Google Caffeine, 360i found that there was about a 15 percent shift in first page rankings.

There also appears to be more relevance placed on Universal results, meaning that SERPs will contain more instances of videos, news, images, books, blogs and local search results, according to 360i.

When looking at the Universal results from Caffeine, it appears that an increasing emphasis is being put on news. 360i notes that currently news makes up about 1 percent of web listings but in Caffeine, news jumps to 5 percent.

Since it was first introduced earlier this month, SEOs have argued that Caffeine will mark a dramatic change in rankings if it were to go live. In a post for PC World, David Coursey called Caffeine “potentially a very big deal” for businesses that rely on their search rankings in Google.

Portable Document Format

PDF Conversion is quiet popular now. Portable Document Format is a file format created by Adobe Systems in 1993 for document exchange. PDF is used for representing two-dimensional documents in a manner independent of the application software, hardware, and operating system. Each PDF file encapsulates a complete description of a fixed-layout 2D document that includes the text, fonts, images, and 2D vector graphics which compose the documents. Formerly a proprietary format, PDF was officially released as an open standard on July 1, 2008, and published by the International Organization for Standardization as ISO/IEC 32000-1:2008.

PDF’s adoption in the early days of the format’s history was slow. Adobe Acrobat, Adobe’s suite for reading and pdf creator , was not freely available; early versions of PDF had no support for external hyperlinks, reducing its usefulness on the World Wide Web; the additional size of the PDF document compared to plain text meant significantly longer download times over the slower modems common at the time, and rendering the files was slow on less powerful machines. Additionally, there were competing formats such as Envoy, Common Ground Digital Paper and even Adobe’s own PostScript format (.ps); in those early years, the PDF file was mainly popular in desktop publishing workflow.

Adobe soon started distributing its Adobe PDF Reader program at no cost, and continued supporting the original PDF, which eventually became the de facto standard for printable documents on the web.

Google helps predict hot search topics

Google has developed a formula to predict the hot topics of online search in what promises to be a boon for companies wishing to target ads that accompany search results on the Internet. Engineers at Google’s laboratory in Israel came up with a forecasting model, while the study of past and current search patterns are reliable clues to what people seek online in coming months. The findings resulted in a new function of the forecast this week for analysis of search in Google.

“We see many search trends are predictable, Yossi Matias, Niv Efron, Yair Shimshoni and the Google Labs in Israel, wrote in a message on the California titan’s website online. “We characterized the predictability of a number of trends on the basis of their historical development.”

Google Trends is a free online search shows what subjects are gaining in popularity or collapse. Outlook for search uses the same data, but is designed for advertisers and researchers who want to deepen. More than half of the most popular search queries on Google are predictable to the extent that a year earlier, with a margin of error of about 12 percent, according to the laboratory engineers Israel.

Categories such as health, travel, food and beverages are particularly predictable, while searches in connection with the entertainment and social networks have proven more difficult to predict, the team said.

Did anyone try Caffeine?

From Google Blog

For the last several months, a large team of Googlers has been working on a secret project: a next-generation architecture for Google’s web search. It’s the first step in a process that will let us push the envelope on size, indexing speed, accuracy, comprehensiveness and other dimensions. The new infrastructure sits “under the hood” of Google’s search engine, which means that most users won’t notice a difference in search results. But web developers and power searchers might notice a few differences, so we’re opening up a web developer preview to collect feedback.

Some parts of this system aren’t completely finished yet, so we’d welcome feedback on any issues you see. We invite you to visit the web developer preview of Google’s new infrastructure at http://www2.sandbox.google.com/ and try searches there.

How Device Drivers Work?

Device drivers are used by the operating system to interact with hardware. The operating system uses functions in the driver to carry out actions on the hardware. Each driver has different functions, and each function corresponds to different hardware.For example, sound drivers helps take care of audio hardware and video drivers take care of the display.

The computer drivers create DOs, short for device objects, for each piece of hardware that it controls. To the driver, the DO is a representation of that specific hardware. The device objects are contained in a device stack. The are the FDO-upper level filter driver, FDO-function driver, Filter DO-bus filter driver, and PDO-bus driver. The stack is made up of DOs for handling an input/output (I/O) for each device.

The physical structure of a device driver is made up of a user mode, I/O manager, and a kernel mode.Breakdown of modes:API–programming application the operating system uses to start the I/O manager.Ntdll–Function library that uses stubs to start the operating system.NtReadFile–System used to create and control I/O requests.I/O Manager–Subsystem in charge of all devices that decides what each driver is allowed to do.IRP–Request packet used by the I/O to ask for information from drivers.IoCallDriver–Sends IRPs to the correct driver that is associated with each DO.In the user mode, the application connects to the API, which connects to the Ntdll. The application request then moves into the kernel mode through the I/O manager. The I/O mangers uses a NTReadFile to process the request and sends it to the IOCallDriver, which in turn sends the information to the correct driver. The driver then decides what to do with the request. It will queue it for later, send it to a hardware port or send it to another driver.

Computer Virus, Spyware and Malware

A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the owner. The term "virus" is also commonly but erroneously used to refer to other types of malware, adware, and spyware programs that do not have the reproductive ability. A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.

Spyware is a type of malware that is installed on computers and that collects information about users without their knowledge. The presence of spyware is typically hidden from the user. Typically, spyware is secretly installed on the user’s personal computer. Sometimes, however, spywares such as keyloggers are installed by the owner of a shared, corporate, or public computer on purpose in order to secretly monitor other users.

Malware, short for malicious software, is software designed to infiltrate or damage a computer system without the owner’s informed consent. The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code. The term "computer virus" is sometimes used as a catch-all phrase to include all types of malware, including true viruses.
