Greatest Linux Command Ever!

March 11, 2009

This is the greatest Linux command ever! Definitely my favorite.
find ./ -name \*.html -printf '%CD\t%p\n' | grep "03/10/08" | awk '{print $2}' | xargs -t -i mv {} temp/

What it does is look (find) for files that end in .html uses the printf option to format the 'find' output, then passes it to grep for searching for a certain date, then awk for printing a certain field, and finally xargs for executing a certain command.

Let's break it down...

The printf part within the find command has the format '%CD\t%p\n'.

%Cx = File's last status change time in the format specified by x. x=D. D=date in the format mm/dd/yy
\t = Horizontal tab
%p = file's name
\n = newline

So basically it outputs the file's last status change followed by a horizontal tab, then the filename, and then a new line.

String 24 SSDs together for 6TB & 2GB/s throughput!

March 10, 2009

What happens when you string together 24 256GB Samsung MLC SSDs - you get 6TB of storage and 2GB/sec throughput. Sweet mother of ---!

Discovered the news on Lucas Mearian's Computer World blog who writes:

When you've got millions of dollars at your disposal, and access to some of the industry's best hardware engineers, what do you do? Well, if you're Samsung you make a YouTube video showing the speed, capacity and reliability you can get by stringing together 24 solid state disk drives behind a RAID controller to create "the world's most powerful consumer computer".

John Chambers Blogs about Broadband Stimulus on GigaOM

March 4, 2009

Om Malik sent a note saying Cisco CEO John Chambers posted a guest blog entry so I went to check it out.

John begins:

Now that President Obama has signed the $787 billion economic stimulus package into law, the real hard work begins: using that money to create jobs. If spent wisely, this package has a chance at fundamentally reforming the U.S. health-care system, making our economy energy efficient and providing Americans with the training and skills required to succeed in a 21st century global marketplace.

But the country can't accomplish these goals unless it has the infrastructure to support them. That's why the funding for broadband was so vital.

ooma Telo vs. magicJack

February 23, 2009

Rich met with ooma recently to see their latest wares and hear about their current business model. Recently, ooma ditched the 'P2P voice network' idea where users actually "share" their home landline with others and instead became a traditional VoIP broadband provider. Apparently, the privacy issues were too much to overcome, since users were concerns about fraudulent activity happening on their home landline by outside ooma users. I had my own reservations about the business model as well, since they claimed it would take 2,000 strategicly placed ooma boxes in all the various local exchanges to get good local call coverage for free P2P calls.

Besides becoming a traditional VoIP broadband provider, ooma is now going to start offering high-end media phones, that according to Rich Tehrani will in the future feature a picture frame, in-house sensors and cameras.

Atlantis found by Google Earth? No way!

February 20, 2009

According to The Sun, aeronautical engineer Bernie Bamford was browsing through Google Ocean when he came upon this formation showing a perfect rectangle the size of Wales lying on the bed of the Atlantic Ocean nearly 3Â½ miles down. A series of criss-crossing lines that looks like a large city enclosed by the a boundary appears in Google Earth. I launched Google Earth myself to see, entered in the coordinates (N31.381 W24.375) and sure enough, there it is.

Now, it could simply be a series of seams in the topographic scans where areas are being tiled together along with missing scan data that has to be interpolated. However, according to The Sun article, Google responded as follows:

Google today claimed the criss-crossing lines were sonar data collected as boats mapped the ocean floor.

But the internet giant said "blank spots" within the lines could not be explained.

31 Million IP Phones shipped by Mayan 2012 Doomsday, the Media Phone, & Slow Consumer Adoption

February 13, 2009

According to In-stat, nearly 31 Million Business IP Phones will ship in 2012. That's if the Mayan 2012 Doomsday Prophecy doesn't come to pass. You know, the one where the Mayan calendar ends on December 21st, 2012 - the same date as the Winter Solstice and when the Earth will be in galactic alignment with the massive black hole at the center of our galaxy, as well as our sun, resulting in a planetary shift. The date 12-21-12 reads as, A-B-B-A-A-B.

Verizon Hub News

January 23, 2009

As I wrote a few days ago, Verizon plans to launch the Verizon Hub. I just learned the Verizon Hub will launch February 1st. As I also was the first to point out, my source told me that the Verizon Hub is essentially the same thing as the Verizon One (created by OpenPeak), which I wrote about in March 2007. In my post from a few days ago, I wrote, "One of my sources told me that the Verizon Hub is the same thing as the Verizon One, but apparently Verizon changed the name to the Verizon Hub deskphone."

The Verizon Hub is the evolution of the Verizon One. As part of that evolution, I hope they no longer restrict you to surfing specific websites. Or if they do have to limit it, I hope the list of allowed websites includes YouTube, Digg, Yahoo!

President-Elect Barack Obama's $40 billion <strike>Handout</strike> Bailout to Internet Providers

January 15, 2009

President-Elect Barack Obama is planning to send up to $40 billion in grants and loans bailout funds toward improving broadband availability and speeds as part of broader economic stimulus efforts, according to UBS analysts.

According to Telephony Online:

A draft of the proposed $825-billion economic stimulus bill circulating on Capitol Hill today lists $6 billion for expanding broadband "so businesses in rural and other underserved areas can link up to the global economy," adding that this provision could well aid the job-creation goals of the larger economic stimulus effort.

PC World writes: The money will "strengthen the economy and provide business and job opportunities in every section of America with benefits to e-commerce, education and health-care," a House Appropriations Committee document said. "For every dollar invested in broadband the economy sees a ten-fold return on that investment."

10X the return? I'm not buying it. My BS meter just went off the scale.

Avaya acquires Nortel rumors

January 14, 2009

With today's news of Nortel's potential bankruptcy flying, my fellow TMC team members have been trading emails back-and-forth about Nortel's future. (See also Rich's overview).

Brendan Read had an interesting take that I thought I'd share:

This could cause a political firestorm in Canada: Nortel being a Canadian company, Avaya being American, expected more job losses from consolidation, Stephen Harper's Conservative minority government being propped up by the center-left parties including a resurgent Liberal party under its US-educated new leader Michael Ignatieff, and the bulk of Nortel's jobs being in the battleground province of Ontario.

Parliament resumes later this month with a new budget--and his deal could add enough explosives to the mix to ignite another election. Harper is a superb political gameplayer which is why he stopped the sale of the firm that made the Canadarm to an American outfit.

He then pointed to an Industry Week article where the sale was blocked by the Canadian government.

So is an Avaya acquisition of Nortel in the works?

Hard Drives Slow Down With Loud Background Noise

January 2, 2009

Apparently, disk drives are more sensitive to minor vibrations than previously thought. A blog post by Sun Microsystems engineer Brendan Gregg called "Unusual disk latency" discovered unusually high disk I/O latency during a streaming write test. He explains how disk drives latency can shoot up dramatically when someone shouts at them making them perform more slowly.

Yes, that's right, he can make his hard drives slow down simply by screaming at them. We've all been there, screaming at our PCs or Macs, i.e.
