space ship design

hull:
1 layer of carbon nanotubes
and 1 layer boron nitride carbon nanotubes
repeat until hull is formed
i predict this hull will be electrical in nature and can absord the mesh of space and create a semi permeated shield of sorts.
the carbon layer is a super conductive state and the boron nitride http://www.beilstein-journals.org/bjnano/single/articleFullText.htm?publicId=2190-4286-6-9 isnt conductive.
so a super conductor and a resistor forms electrical and magnetic condutor and will i think repell a small portion of space.

rant

a question poped in my head.
if aliens exist wich languange will they use?

well if it is written languange maybe a 3d language based on geometric 3D shapes like a cube or something like that
or maybe the smallest base forms like atom shapped and universal carbon atoms.

life tip for network people

came to a life conclusion you must have at least 4 dns servers on your network and 3 dhcp server in cluster took me 20 years..

wireless sprawl

no i didnt make a mistake...
welcome to the age of mobility and BYOD and collaboration  for the IT manager its not welcome its a waking nightmare, lets start at the beginning:
in our company we recently had to implement a project that required tablet use so i had to implement the wireless access to those tablets, we had some 4 access points for intermittent use, so i did a site survey measured the wireless aps calculated for 9 tablets the use and did web study and contacted suppliers and did those things that normally CIO does, and decided that for 6 ubnt ap-pros that fit the bill Cisco was toooooo expensive and the ubnts proved to be plug install and forget...
that's when the problems started now we have to provided guest access and the employees demand that wireless access to they're smartphones it took 2 months to pass from 9 tablets to 32 devices and growing by the day..
my advice is beware of wireless sprawl... i accounted only for 10 devices and some intermittent use...
but the ubnts proved to be unbreakable and unshaken and i saw one day 48 devices connected and 30 guests not a problem.
just my two cents...

Blackberry with Exchange Server 2013

BES does not work don't even bother you can search everything.. 

you have to change to bis and you thought well there's is always "owa" right? wrong...

you have to enable imap and change my entire network so blackberry server can reach exchange server.

heres how:

go to the firewall and enable 993 and 114 ports from outside to the middle firewall

i have a physical and software firewall.

in the middle firewall you must publish exchange server 2013 imap4 and pop3 and 993 ports

then go to the bis blackberry and you can say bye bye to 2 days work trying to get things to work.

but i did and it works bear in mind there's a 15 second delay between the send and receive in blackberry devices..
