Why the computing world chose PKI

Why the computing world chose PKI

In Phil Zimmermann's response to "Does Phil Zimmermann need a clue on VoIP", Zimmermann offered a blistering attack on PKI based solutions and offered his own PGP solution as the superior alternative.  There is just one little problem: the computing world chose PKI for the most part while PGP barely makes a dent in the email world.

Does Phil Zimmermann need a clue on VoIP?

Updated: 8/5/2005 @ 4:06 am Phil Zimmermann of PGP fame, a legend in the cryptography world, was cooking up a new secure VoIP brew at last week's Black Hat conference--but could he be just a little bit out of touch?  As much as I respect the man's intellectual prowess and his contribution to the field of cryptography, I don't think I can say the same about his product design skills.

Are FCC radio spectrum policies obsolete?

Are FCC radio spectrum policies obsolete?

In my previous blog on "Getting beyond the WiMAX hype", I tried to put WiMAX in to some proper perspective of what it can and cannot do.  From some of the responses that I've gotten, it appears that my WiMAX blog has thrown some cold water on the dream of running a private long range wireless LANs with WiMAX.

Is the XP SP2 firewall getting a raw deal?

Is the XP SP2 firewall getting a raw deal?

A recent report on a new denial of service vulnerability involving Windows RDP (Remote Desktop Protocol) blaming the Windows XP SP2 (Service Pack 2) firewall has touched off a rash of sensationalism from other media outlets that gets blindly regurgitated in the forums.  This has caused some unwarranted confusion and fear in the IT industry.

So much for Oracle never breaking

So much for Oracle never breaking

A few weeks ago, I wrote this piece on absurd marketing claims in the latest Oracle TV ad that claims "never breaks".  After seeing these ads almost every other night since then, we get news that Oracle just released their latest mega patch that addressed 49 security issues.

Clarifications on Intel Centrino branding

Clarifications on Intel Centrino branding

In my last blog on Centrino in response to David Berlind's blog, I weighed in on the issue of Centrino branding.  After further discussions with David Berlind, I realized that I may have been a bit unclear about some things and misused the word Centrino in the context of a product rather than a brand.

Chiming in on Centrino

Chiming in on Centrino

Fellow blogger David Berlind has been on a crusade to add a little truth-in-advertising to the Centrino marketing campaign and I've been following it over the years.  Centrino is a massive marketing campaign to make wireless LAN synonymous with Centrino when in reality it just isn't so.

The war for the living room PC has begun.

The war for the living room PC has begun.

Pundits have been predicting the demise of the personal computer in favor of the TV set-top box for more than a decade, but history has proven the PC to be very resilient with many homes owning more than one PC.  While the PC as we know it won't be going away anytime soon, a new war may be opening up in the living room with Microsoft XBox360 and Sony PS3 facing off.
