قبل از هر چيزي بايد از دوستاني كه در وبلاگ نظراتشان را ارسال كرده بودند تشكر مي كنم. اين كار مرا تشويق به نوشتن بيشتر خواهد كرد چون تاثير آن را مي بينم. دانشجويان رشته هاي مهندسي بايد در انتهاي دوره كارشناسي خود درس پروژه (و نه پايان نامه) را بردارند . معني اين نام اين است كه بايد يك كار عملي كه بزرگتر از پروژه هاي درسي مي باشد را ارائه دهند. اولا براي ...

At Google we are fanatical about organizing the world's information. As a result, we spend a lot of time finding better ways to sort information using MapReduce, a key component of our software infrastructure that allows us to run multiple processes simultaneously. MapReduce is a perfect solution for many of the computations we run daily, due in large part to its simplicity, applicability to a wide range of real-world computing tasks, and natural translation to ...

This is, without a doubt, the most interesting thing I have read in quite some time. Google's operations are so epic...48000 hard drives to sort 1 PB a data across 4000 computers in 6 hours. That is totally out of the realm of normal experience. And they said they processed 20 PB/day in January 08 - I wonder what it is now...

Dayamn! Google sorts a terabyte in 68 seconds and a petabyte (1,000 terabytes) in six hours!

We are excited to announce we were able to sort 1TB (stored on the Google File System as 10 billion 100-byte records in uncompressed text files) on 1,000 computers in 68 seconds. By comparison, the previous 1TB sorting record is 209 seconds on 910 computers.

Now this is useful information. How to intelligently and correctly implement NAND Flash (ugh maybe in SSDs) and or RAMSAN systems for this as well. It depends on large data so really hard drives must be the optimal media of choice.

Eighteen days ago, I published an entry titled "Conflict in Congo, refugees on the move", which showed some of the initial chaos resulting from the war erupting once again in the eastern Democratic Republic of Congo (DR Congo). In the days since, the civilian population has endured more continued fighting amongst multiple factions, cholera outbreaks, separation from family members, hunger, and further losses (of life, property, safety and trust) as both rebel forces and government ...

How did Internet Explorer become the number one browser in the world? Simple - it came with every new computer you purchased, pre-installed and ready to go. Now it seems Google is contemplating doing the same with their browser, Google Chrome. According to Google VP, Product Management, Sundar Pichai, the browser's beta period will end in January and then they "will probably do distribution deals," he says. Sponsor In an article that ran in yesterday's ...

This is pretty scary--Google would take the monopolistic late 90s Microsoft approach to distributing their search. Another scary point is that if Netbook uptake is high, Chrome could be distributed with both the Linux and Windows versions. This is quite far from the idea of open web platforms that Firefox had intended and effectively locks users into only one search provider and platform.

While I really love Chrome it still has some time needed in the oven. The security issue needs to be patched as well as I know I personally would love to see them integrate Google Bookmarks into Chrome to offer a way to take your bookmarks to any Chrome browser you sit at.
