internet kaspersky security: You should follow Polar Bear Farm

During the Kiwi Foo Camp 2008 I had a chance to meet Layton Duncan. He's quite active on Geekzone, mainly in the Mac OS X Mobile forum, helping others with their iPhone and iPod touch questions and comments.

He is also involved with Polar Bear Farm and I think you should follow the company.

Why you should follow Polar Bear Farm? Because it's a New Zealand company creating application software for the Apple iPhone and iPod touch.

They are the guys behind the PBF Search and PBF ShowTime - this one brings video recording to the Apple iPhone.

I just wanted the guys added more posts to their blog - I know they were shoing off their stuff during the MacWorld but it would b good to hear more of their experience of going to that big show.

Changing MAC address
I was asked this and didn't know the answer, as the boxes I have had always have unique mac address, so it was never a problem... however it was pretty easy to change as detailed below:

Telnet to the DM, and type the following commands:

cd /var/etc
rm init
echo \#!/bin/sh >> init
echo ifconfig eth0 down >> init
echo ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx >> init
echo ifconfig eth0 up >> init
chmod 755 init
reboot

You need to change the xx:xx:xx to the mac address you want. Then the box will reboot... and the MAC address is changed. Easy!

Ojo videophone: can you see me now?

If you are one of the people who bought an Ojo videophone from Telecom New Zealand (announced down here back in November 2006) then start worrying.

It seems Worldgate is in the path to bankruptcy:

Accordingly, on January 30, 2008, the Company shut down its operations as a first step to winding down its business, which will occur if the Company is not able to secure payment of the monies believed to be owed and/or new financing. The Company continues to explore potential financing opportunities and is also pursuing legal recourse against the customer. Thus, bankruptcy may be coming shortly, which would be another black eye for the VoIP industry...

And just minutes ago I read on Engadget that the service has gone dark.

Is anyone here in New Zealand still using the Ojo through Telecom New Zealand?

Dual booting Vista and Windows Server 2008??
I have Vista Business in one of my machines and thought of dual booting with Windows Server 2008. And the end result? - Excellent! I installed Windows Server on top of Vista and after installation of Windows Server 2008, the boot menu was shown with options to boot into Vista or Server 2008 Cool

A beginners guide to DIY structured cabling in a new house - Part I
There has been quite a bit of discussion on Geekzone lately discussing structured cabling for voice, data & TV. There is a great thread here that talks about home wiring with GZ's resident expert cyril7 providing some great advice on the topic. As my family are currently building a new house (that is for sale if you're after a place in Lower Hutt!) I thought I'd give a quick DIY guide for anybody who's looking at options for a new house or renovating an existing one.

Now I must confess that I am no expert when it comes to wiring and I don't do this for a day job! I'm sure there are probably a few others out there who can probably give me a few tips or advice and correct me on some things! :-)

So why install a structured cabling system? My answer? Why would you not install a structuctured cabling system! Telecom have recommended now for several years that all new houses be wired with a minimum of cat5e cable in a star configuration back to central point to replace the conventional method of running phone cabling in series between jackpoints. There are still a surprising number of "experts" in the trade who are still stuck in the dark ages and continue to stick to this but the reality is no new home should be wired like this any longer.

With multiple phones, multiple internet connected PC's and cable or satellite TV now the norm in many homes a structured cabling system is a logical approach and also doesn't need to cost the earth - for an average new house the cost of an entire fitout consisting of cable (cat 5e and RG6), patch panel, and all sockets shouldn't cost you more than $500. Right now wireless is still nowhere near as fast as Ethernet for computer networking and cat5e cable can also carry a myriad of signals ranging from phone, ethernet right through to component video and HDMI with appropiate baluns. With the VoIP era also about to approach you've got to be crazy to not be prepared while you have the opportunity!

This is a 3 bedroom house with open plan kitchen and lounge with a semi detached dining room which could easily be used as a study or kids play area or converted into a bedroom. My plan has been to use 12 cat5e jackpoints around the house and F connectors for RG6 for TV in all rooms. This is all run back to a 16 way patch panel in a hallway cupboard. The lounge has 3 RG6 sockets allowing for a terrestrial aerial, satellite dish and a return feed so the output from your STB can be viewed on any other TV in the house.

Master bedroom: TV + dual RJ45 + single RJ45 next to bed for a phone
Bedroom 1: TV + dual RJ45
Bedroom 2: TV + dual RJ45
Dining/Study: TV + dual RJ45
Kitchen: Single RJ45 for phone
Lounge: TV + dual RJ45

The choice of a 16 way patch panel allows 12 sockets wired back to jackpoints with the last 4 jumpered back to the incoming phoneline so they can be patched as required. The incoming phoneline is terminated in a standard jackpoint on the wall (which also serves as a test point as required by Telepermit regs) and this is then connected to port 16 on the patch panel and jumpered across to 15,14 and 13.

This house will have TelstraClear cable service provided to it so there is no provision for a central ADSL line splitter however this could obviously easily be retrofitted if needed. If you're like most of the country and rely on ADSL for your broadband this is something you will want to factor in as it's so much simpler and tidier than requiring filters on every jackpoint that will have a phone on it.

This layout is probably about the bare minimum you would want to install in a house, it's certainly much cheaper to run extra cable when a house is being built than later on wish that you had done it so!

Choose a logical place to wire all your cable back to. A garage makes a great place but a hallway cupboard is really your only choice if you don't have an internal access garage. Remember to also install a power point nearby as you'll need this for your modem/switch and things such as a VoIP ATA. A wall mounted rack cabinet makes things look nice and tidy if you have space and remember that you may want to have your network running off a small UPS since they are so cheap these days so factor options such as this in when you're working out the dimensions.

So on with the pictures. First up is a quick view of the inside of the house with most of the electrical wiring now done.

Use 25mm drill bits for all wiring holes. Be wary of any structural walls if you're drilling multiple holes in the same beams - ask a builder for advice if you're unsure. Also remember that flush boxes need to be flush - if they stick out you'll have trouble attaching the jib to the wall. Also try and avoid running cable near power, if at all possible try and stay a minimum of 200mm away with the main cable runs. Running plugs on the opposite side of a stud is an easy way to keep cables seperate at the jackpoints. If you do need to cross power cables (and there are times where this can't easily be avoided) ensure the cables cross at right angles and do not run parallel to each other.

Use electrical tape to bundle cat5e cable together. While solid cable is fairly robust it is not invincible. Do not staple this cable or run it at extreme angles. Cable ties stapled to beams are a good way of attaching cable but again do not tighten these up fully as it could easily damage the cable.
