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.

VoiceGear SkyBridge at ITEXPO

February 3, 2009

IndustryDynamics' VoiceGear SkyBridge is a Skype-to-PBX product that works with analog and VoIP PBX systems and connects them with the Skype network. I stopped by their booth at ITEXPO to learn more. They told me that SkyBridge supports up to 60 Skype accounts and up to 4 simultaneous Skype channels. They demonstrated the web interface used to provision Skype accounts and other settings.

TechCrunch Touchpad - Needs 3G/4G/EVDO, Skype, and VoIP

January 19, 2009

TechCrunch has a prototype of their tablet PC featuring a touchscreen, Wi-Fi, an accelerometer, a camera and a four cell battery running on a stripped down version of Linux. Well, actually they're running the prototype on full-fledged Linux, but they promise better performance once they strip out all the extra stuff.

According to TechCrunch:

The device has a 12-inch touchscreen with a 4:3 aspect ratio (which is ideal for web browsing in my opinion). It is powered with a Via Nano processor, which has performed at par with the Intel Atom in our testing. 1 GB of ram (its more than we need) and a 4 GB flash drive to store the OS and browser and any cache.

MovableType Facebook Connect Problems and Fixes

January 7, 2009

I've been testing the Facebook Connect plugin for MovableType 4.23 for the past few days. It's in beta, so I expected to encounter some issues. However, it was so close to working 100% that I stubbornly tried to fix the bugs myself rather than wait for Sixapart to fix them. I thought I'd share what I learned and save you hours of troubleshooting yourself.

trixbox CE vs. Asterisk Downloads

December 23, 2008

As you may have read, Digium announced a sharp rise in Asterisk downloads for 2008 registering in a whopping 1.5 million downloads for 2008. That got me thinking just how does Asterisk & AsteriskNOW compare with Fonality's trixbox CE distro? Arguably trixbox CE is the either the #1 or the #2 downloaded Asterisk-based distribution. But are they #1 or #2?

Logitech QuickCam Vision Pro webcam for Mac

June 24, 2008

Logitech today unveiled its first Mac-compatible webcam with premium autofocus technology and Carl Zeiss optics - the Logitech QuickCam Vision Pro webcam for Mac. The new Logitech webcam of course works with iChat and Skype and features a 2-megapixel camera sensor.

The new Logitech webcam uses a voice coil motor for its autofocus system, instead of a stepper motor. According to the news, "Focusing is fast and fluid - crisp even in extreme close-ups only 10 cm from the camera lens. Logitech's autofocus system compensates for changes in image-edge sharpness and refocuses images in less than three seconds"

What I don't get is why Logitech chooses to make operating system specfic webcams. Isn't USB supposed to be an industry standard?

Asterisk With Office Communications Server 2007

May 27, 2008

Asterisk integration with Office Communications Server 2007 is a popular topic in the unified communications community. You wouldn't think integrating an open source Linux-based solution (Asterisk) with Microsoft's proprietary OCS 2007 UC platform would be popular, but it is. In fact, I have my ear to both the Microsoft OCS 2007 community and the Asterisk community and the integration of these two worlds is something I hear all the time. Some within the Asterisk community poo-poo the thought of integrating with Microsoft OCS 2007.

Hulk Smash Asterisk 1.6!

April 16, 2008

Nerd Vittles had been lamenting the fact that the "Asterisk 1.6 development seemed to be on a collision course with the dinosaurs because of developer insistence on deprecating and removing commands from the application programming interface (API) in the name of technology enhancement."

Nerd Vittles then explains why this is a bad idea.

The problem this poses is that applications and dialplans written for previous versions of Asterisk no longer function even though the code is barely a year old. In the corporate and government sectors, this would mean major, costly (annual) rewrites of code just to keep a functioning phone system. And, as we noted, these organizations buy phone systems to last a decade so such a development strategy would all but rule out use of Asterisk in the Fortune 500, medical, and government sectors.

PIKA T1/E1 and analog boards now compatible with FreeSWITCH

April 15, 2008

PIKA T1/E1 and analog boards are now compatible with FreeSWITCH.

Some good news for PIKA this morning worth reading...

PIKA Technologies Inc., a developer of media-processing hardware and software, today announced that its entire family of analog and digital host media processing (HMP) boards is now compatible with FreeSWITCH, an open-source telephony platform typically used by large telecommunications companies deploying soft switches and other voice applications.

This is the latest partnership that PIKA has announced as part of its mission to support open-source-telephony application developers, having previously announced compatibility with the Asterisk platform.

"PIKA is thrilled to be partners with the FreeSWITCH community. This will mean more options for application development companies across the globe who are building FreeSWITCH-based solutions," said Terry Atwood, vice president of sales, marketing and customer care at PIKA. "Now, FreeSWITCH users will have access to PIKA’s robust media-processing software and hardware, and as a result, be able to stabilize as well as add incremental value to their applications."
FreeSWITCH is designed to facilitate the creation of voice and chat-driven products scaling from a soft phone up to a soft switch. It can be used as a simple switching engine, a PBX, a media gateway or a media server to host IVR applications using simple scripts or XML to control the call flow.

"I was really excited to get PIKA hardware working in FreeSWITCH," said Anthony Minessale, Lead Developer and author of FreeSWITCH.
