NPD: VoIP Traffic Isn't Just Normal Traffic
VoIP traffic has additional performance requirements and real-time characteristics. It uses the Real-time Transport Protocol (RTP) which rides on top of UDP. UDP is a connectionless protocol - there's no retransmission of data, there's no re-ordering of data. RTP applications typically send packets at a fixed rate. If a packet is lost, it's lost, and there's no chance to retransmit it. Voice conversations are interactive in nature, and thus not very tolerant of large delays. The network causes a certain level of delay and if this delay is large enough (usually more than 150 milliseconds), it's going to be very difficult to talk to someone.

After all, the cellphone guy doesn't say: "Can you hear me 150ms ago?"

Blue Flavor: Project Management Made Easy
Look at what you need to do. Break it down. As a project manager you’re probably not going to have to do all the work yourself. You just need to make sure that it gets done, is done right, is done on time, etc. What are the tools you need to do that? A proper plan, good people, clear expectations, good communication, a timeframe, deadlines, a budget, etc. If you really take the time to look at it all, you’ll likely see that with a little thought it’s pretty manageable. Whatever you do, don’t go making a mountain out of a mole hill.

Unless of course, the project is literally creating a mountain out of a mole hill...

Lifehacker: Turn your $60 router into a $600 router
Of all the great DIY projects at this year's Maker Faire, the one project that really caught my eye involved converting a regular old $60 router into a powerful, highly configurable $600 router. The router has an interesting history, but all you really need to know is that the special sauce lies in embedding Linux in your router. I found this project especially attractive because: 1) It's easy, and 2) it's totally free.

This is geared more towards consumers than networking pros, it's still useful to have a few cheap "backup" routers laying around in a "worst case" scenario - to bandage the wound until the real replacements can arrive.

IT Business Edge: The Elusive Quest for Intranet Search
From a technology point of view, there are three keys to effective intranet search: metadata, taxonomies and controlled vocabulary. Unfortunately, all three impose huge – some would say unworkable – burdens on the people who are meant to use the systems based on these technologies.

Metadata: Data that's so self-aware, it's ironically hip.

Enterprise Archetecture: Why aren't folks from large enterprises blogging?
You can take an arrogant stance and simply ignore us by labelling us as enterprisey or you could do something more thoughtful by embracing us and more importantly the capital we can bring to the table. Keep in mind that the demographic you eschew happens to represent 90% of all IT people on the planet, so in not participating with us you are ignoring the masses.

Dude. I'm like... standing right here...
