BLISS — Service Interoperability

Those of you who have been in the industry long enough know that the vision of SIP is not fully realized because of interop issues between vendors with the most basic of business telephony features. There have been various efforts by industry groups like the SIP Forum and individual vendor initiatives like Sylantro usually results in competitor comments about the implementation being proprietary, etc. The back-and-forth understandably keeps going on. This ends up frustrating customers and end users. There is hope finally! The SIP chairs have now decided to tackle this services interoperability issue head-on by getting together a BOF called BLISS. The name is apt and I would strongly recommend that any of you who are in the industry support this initiative and actively participate in the discussion.

Off for a few weeks

Hi Readers, Just a short post to let you know that this blog just may be quiet for the next few weeks (hopefully shorter). I am in the process of discovering how lovely yet strenous it is to manage our newborn son :-) A Note to my friends from Russia: Thanks for your email – I apologize for not having responded yet – I will certainly put some thought on your questions and write back by next week.

Indexing should get smarter for bloggers

There are several reasons why Bloggers post. A part of it, I believe, is to share technology and for many, including me, it is a great tool to meet like minded technology people, who often respond by private email. But, I’d be willing to go out on a limb and state that the biggest reason most bloggers blog is that they like to have a podium to talk and be heard, albeit virtually. This also means, therefore, that a vast majority of the bloggers (including me) are ‘hitcounter’maniacs. We love to log in and see how high up our ‘hit count’ is for the day, and who referred to us. There. I said it. Nothing wrong with it. I love what I call ‘ego searching’. It’s not a term I invented. PhpBB forums have used this term for many years. And this is where I think major search engines like Google and Yahoo can do a better job. See, both of them give you an option for either searching within other blogs (who in the blogosphere links to you) or the whole web. The former is limited while the latter is problematic. Let me explain. There is a difference between

Burn those virtual calories

“Please change MOV AX,0 to XOR AX,AX. You save bytes. Also, please use shift operators instead of divisions. You save on cycles” Common speak during the days of DOS and protected mode coding – when C and ASM worked hand in hand. Then came the ‘abstract high level programmers’ who never really cared about declaring an int where only a byte is needed, or use multiple structs where a union would suffice.Then came the ‘Object Oriented’ programmers who never really cared for understanding how virtual functions really worked or how they affected performance and/or size and used it pretty much everywhere without blinking an eye.Then came the visual programmers who would love to drag and drop ‘graphic objects’ that would increase productivity by 150% and reduce time to market by 300% ! Woo haa. It’s another matter that each ‘visual object’ generated 300-500 lines of gob.Then there was XML & buddies – the whoopie-doo do it all markup language for representing anything.And DHTML and Javascript to add funky effects and client side programming to increase ‘web interface coolness’.Then came the idea of using the Internet for communications !Then came SIP, a great text based protocol, which generates anything between 500-1000
