Convert whole iTunes library to MP3

Ok, to avoid arguments with the kind of people who come on pretty strong screaming about 'why you'd want to do this' and 'how Apple's AAC or Loss-less formats are better' let me just take two seconds to explain my situation.

I am running an Apple iMac 27" with a collection of music stemming about 10 years, not massive; about 50GB-ish.  Now I have decided to purchase an OEM Car stereo which allows me to play my music from a Micro SD Card! :O I hear you gasp, yes technology is wonderful.  My problem of course is, these kinds of players only find and play MP3 formats from these disks...  So, now we have that out of the way; I'm going to let you in on a little trick I thought about which will allow you to achieve this.

My criteria for doing it this way, includes:

* The files MUST be in the same folders as the source - I don't want 1000's of mp3 files exported into the same folder so I can no longer identify tracks or Cd's!
* The original files…

iPhone / MAC can't connect to Exchange Server from inside the network.

I believe this is a relatively simple one in the case I've witnessed anyway.  The scenario is that you turn on WiFi, connect and then lose access to the exchange.  Turn off WiFi go back to 3G and voila you're connected again.

The reason that the phones and iMail (to name a few) cant connect to the Exchange from inside the network is because you will most likely be using an external IP or URL right?  Thus meaning that everytime you try to access this URL from inside the server bounces packets backwards and forwards around the network not truly knowing what to do with them. 

I found that if you create a new DNS zone for (mail.domain.com), create an A record within that zone leaving the host blank (to use parent domain). Then point it at your internal exchange. 

This time if the users phone requests connection to mail.domain.com they get redirected (internally) to 192.168.x.x/24

Simples.. :)

Note - You may not need to make a new zone if your domain is already running as the p…

Reset Windows 7 Local Administrator Password

Ever been locked out of your Windows Vista / 7 Machine. Forgot to enable or create an account for that all important day that you get 'no logon servers available' or 'the trust relationship failed' well this has to be the single most, utterly awesome hack known to the IT world in my opinion!

You will need a Windows 7 CD.

1.Boot from the Windows 7 CD and click repair my computer, then follow the prompts to get through to using Advanced tools for repair and then command prompt.


2.Type C: to change letter from (normally) X: to the active partition.
3.Type the following command:
copy c:\windows\system32\sethc.exe c:\

This creates a copy of sethc.exe to restore later.

4.Type this command to replace sethc.exe with cmd.exe:

copy /y c:\windows\system32\cmd.exe c:\windows\system32\sethc.exe

Reboot your computer and start the Windows installation where you forgot the administrator password.

5.After you see the logon screen, press the SHIFT key five times.

6.You should see a comma…

Biphasic Sleep Experiment - Day 1

Let me bring you into my story first..


So, normally I wouldn't immerse myself into experiments; I'm normally the cautious side-liner that would watch, observe and then when proven will follow! I have however taken on this role of health conscious Haynes and after panning down all those Easter eggs this March, I think it's time to evaluate my fitness regime. The problem I have as an individual; is that when I get home at 6pm, it's time for tea, half 6-7 undress, redress and get ready for the evening and then I either go out to meet friends or go out to my Photography club all of which I enjoy but it does take up a lot of time. By the time I get home, we're normally around 11/12pm and I'm up at 8am very tired, to then shower and run off to work for 9am.


I want to have some time to exercise but finding it around my schedule is difficult. I've done some research and to what I understand, I've been doing this so long that my agenda is written very strongly …

Time Machine Full Not Deleting Backups Mac OS X

See, I said this would happen didn't I.

I managed to break every element of Windows and now I'm even managing the same with MAC OS X!

This one got me for a while though, basically I found that my 500GB External Passport Drive was full, it made sense because the day prior I moved 200GB of data from one location to another, so I guess the time machine simply presumed it would backup the same data but in different locations hence running my drive out of space.

The issue was that Lion (to my understanding) would delete old backups in order to fix the space issues on my drive, apparently this seems like it isn't quite accurate. You have to go into Time Machine and Delete the old files you don't want anymore. So here's how I did it, I spent ages in that stupid Time Capsule Preferences window with barely any settings to change and just shy of chucking the machine through the window i noticed that in the top right where you locate the Time Capsule icon you can actually hit…

iMac 27" WiFi losing connection intermittently

In the aid that this helps anyone I thought I'd post it up there with my normal helpful stuff :).

This week I decided to finally bite the bullet, you can see through my exhaustive blog that I have found and fixed my fair share of Windows OS problems and it's only fair I give MAC OSX it's shot. So I invested in a brand new 27" iMac, Quad Core 3.4Ghz i7 with a 1TB hard drive I was more than looking forward to working on this bad boy.

I was incredibly disappointed when I took it home though, to find that at least three / four times an hour I was having frequent drops in Wireless Connection. I have a decent wireless router (Yes I'm perhaps 30ft away) but I can sit in my car outside (60ft away) and still get a good signal on my iPhone.

I found a few 'hot fixes' online, something about in Network Preferences, set it to a new name and not Automatic. I gave it a try, no joy.  So amongst my troubleshooting steps I took note of every change and tested and tested and…

Renewing a self signed SSL Certificate in Exchange 2007

Ok, so I've actually seen this problem so many times now it's unreal and people are always asking me how to fix it because most other guides on the net make it look way to complicated to properly comprehend. So, here goes. This is how I renew an Exchange 2007 SSL Certificate when you get the notice in Outlook it has expired. N.B - The process for renewing through a verified authority like GoDaddy / 123 Reg is not discussed here.

First thing you'll need to do is logon to your SBS 2008 (Ex2K7) box as the domain administrator and open the Microsoft Exchange Management Shell.

Type the following command:  Get-ExchangeCertificate - This will list all of your existing certificates by Thumbprint and CN (Common Name).

You'll need to know the CN, if you're unsure match it to the certificate error being presented in Outlook. History tells me it's normally the remote.domain.co.uk that controls the Ex Cert on SBS.

Now, using the identified Thumbprint of the certificate you…

Configuring QoS for SIP / VoIP

Unless you have a true understanding of the layer protocols and technologies behind SIP, setting up QoS can actually be quite difficult, as I found out myself.

Interestingly when setting up SIP you often set the firewall port to 5060 and leave it at that, so you may simply assume that 5060 is the only required port. What you forget though, is that this is only inbound; what is going outbound?

So my personal understanding of SIP (and some wiresharking later) is that it tends to use the following protocols.

Signalling via port 5060. ALSO each line after uses upward one port.Line 2 5061, Line 3 5062 etc.
Realtime Transport (RTP) 10,000 - 20,000 varying per call.
STUN 3478/3479

So you see straight away that setting QoS to prioritise 5060 will do next to nothing on your network you need to put in three ranges. 5060-5080 (20 lines), 10,000-20,000 & 3478/3479.

All of the above only need to be UDP.

Putting these ports into QoS makes a huge difference to the quality of a call for me. I'…
