Our stacks and frameworks run over an operating system abstraction layer called “Common Core“. This allows us to be able to port our products in a relatively short timeframe to other operating systems – sometimes really esoteric ones. In some cases, our customers do the porting to their operating systems on their own – especially when they use a proprietary one that is only available to them. I’ve even met a customer or two that have taken some of our

Yesterday, a project that I have been involved in for a long time now has been publicly announced for the first time. This might not surprise you, if you have been following this blog for a while, but here’s my latest pride and joy: a high definition videophone SDK optimized for the TI DaVinci HD system-on-chip. This announcement fills me with pleasure – I’ve been part of this effort for a very long time, from its very consumption through the

Up until not long ago, Skype was solely a downloadable VoIP client for a PC. Nothing more, nothing less. They even allowed third parties to tap in and add their own functionality to their Skype by using an SDK for developers. One thing, however, always remained closed – the communication protocol. While the rest of the world is using H.323, SIP and sometimes XMPP to do VoIP, Skype did… Skype. What does this mean? That Skype needed to conquer the

The greatest challenge of my work is to explain exactly what our business unit is doing: Friend: “What exactly it is that you’re doing?” Me: “I am a Product Manager” Friend: “Yes, but of what products?” Me: “Well, we cater for VoIP developers” Friend: “VoIP?” Me: “You know, when you use Skype to call people over the internet? That’s VoIP” Friend: “Oh, so you do Skype?” Me: “No. Not exactly. We enable companies who want to develop products like Skype to do so. But not Skype. Skype is proprietary.” Friend: “So what do you do again?” You get my drift. The TBU (Technology Business Unit) develops standard compliant VoIP protocol stacks and SDKs for developers, who then develop their own products. That’s a mouthful. And now that we have a new video clip, it should make it a lot easier to explain what I do to my friends: Hope you’ll like it as much as I do.

MobileCrunch recently compared Android OS with LiMo. Both are viewed as Linux-based platforms for handsets. However, I think they missed a crucial point – Android OS is simply not Linux.I’d like to first fix the comparison table on MobileCrunch’s post based on the interesting comments found in that specific post. Here is a list to summarize the differences: An SDK will be available in LiMo “soon”. Probably later on this year. With Android having one, I am sure

A lot of reviews have been done on Office 2007 – this is not going to be one of them. I just had the questionable opportunity of working with Microsoft Office 2007. It can be a very frustrating experience to anyone used to previous Office versions. Office 2007 can serve as a great lesson on how to plan new versions – especially when the customers are engineers. Our company has just migrated to Office 2007 this week. It has

[I've had a chat the other day with a colleague of mine, Danny Loeb, who is the Product Manager for our SIP Server Platform. As part of his work, he needs to deal with the multi-core trend and how that changes the architecture of his product.] Multi-core is all the rage these days. Or at least this is what Intel tell us – almost every month Intel arranges a seminar, workshop, training or some other session about multi-core here in

No company today is capable of developing its products in-house without using 3rd party software. In most cases the process starts from outsourcing the operating system itself, continues with outsourcing specific protocol stacks and user interface engines, etc. These come from vendors which are sometimes called ISVs (Independent Software Vendors), middleware vendors or various other types of manufacturers.I came across Åse Stiller’s guest post on VisionMobile, where he recommends vendors build an end-to-end flowchart of how source codes of their
