Privacy Badger - Stop Third Party Trackers

Privacy Badger is a browser add-on that stops advertisers and other third-party trackers from secretly tracking where you go and what pages you look at on the web.  If an advertiser seems to be tracking you across multiple websites without your permission, Privacy Badger automatically blocks that advertiser from loading any more content in your browser.

Its in Beta but I have been running it in Firefox and Chrome and its working well, limiting the tracking for Ads and webpages are loading faster so check it out!

Forget the Nexus 6001 the Nexus 5600 just replaced it! well kind of....

Cisco look to have rebranded the Nexus 6001 in to the Nexus 5672 platform but added Fibre Channel support.

They have also released a 2U logical replacement for the Nexus 5596 called the Nexus 56128, somewhat confusing for the customer and kind of brakes there numbering schema they have been running, Cisco a bit more planning, Prior Planning Prevent Poor Performance? Bit harsh but hay, they were announced at Cisco Live Europe, the Data Sheet is out at but the from my CCO login I can’t get a price on anything other than software upgrades as yet!

Well the upshot, can’t see why you would buy a Nexus 5500 or the Nexus 6001 over the new Nexus 5600’s once you can actually get a price for them ;-)

Also announced the Cisco Nexus 3172 it’s a 10-Gbps SFP+-based ToR switch with 48 SFP+ ports and 6 QSFP ports, allot of forwarding power to Top of Rack!

Nexus 5548 vs 6001

The Cisco Nexus 6001 provides higher port density, 48x10G & 4x40G, throughput, built in Layer 3 and 40G uplinks, although it only supports FCoE not Native Fiber Channel as the 5548UP.  The lack of FC on the 6001 Leaf switch however is not a big problem as I'm sure that Cisco will be building a 1/2/4/8 Gbps SAN Fiber Channel card for the 6004 allowing for converged networking in the future at the Spine.
