iOS6 is here. Is it worth it?

Apple iOS 6 Upgrade available today, is it worth the trouble?

We’ve already upgraded our iPads, iPods, iPhones, well, all of our iDevices and in short, what device gets what?

After 5 minutes the following new features caught our eye…the upgrade is well worth the wait. It is packed with over 200 upgrades (you can read all about them in your ‘more details’ link in your iDevice) however not all features are available on all devices. If you have an iPhone 5 (lucky lucky you!) or an iPhone 4s then you get every new feature.

Siri – Until now, Siri was only available on the iPhone 4S. Well with iOS 6 you now have Siri on the New iPad. Siri is also much improved and can post directly to your Twitter and Facebook accounts. With greater language support Siri has taken a big step in the right direction.

Maps – A huge change and a move away from Google Maps. Apple now use their own Maps app which come with cool new features such as 3D maps, turn by turn navigation, real time traffic information and more.

Facebook Integration – all devices get this upgrade. You can now share photos directly from the camera app or post your current location directly from Maps. Your Facebook events are also automatically synced with your Calendar app.

FaceTime over cellular – for iPhone 4S and the New Ipad only. Use up all your mobile data allowance fast with this cool new feature! More useful for devices with 4G support.

Panorama Photos – A new feature for the iPhone 4S provides the ability to take Panoramic pictures, no longer requiring a third part app. Sadly, this feature is not available on any iPad devices.

If you have an iPhone 4 then there has never been a better time (or bigger requirement) to upgrade to the 4S. Features that the iPhone 4 will not receive with iOS 6 include Facetime over cellular, Flyover, Panorama, Turn by turn navigation and Siri.

If you have an iPad 2 you will not receive Facetime over cellular, Panorama (not on the New iPad either) or Siri.

Well there’s hundreds of new features and fixes, we are excited about the upgrade. So what are you waiting for, start downloading your iOS6 now and get some exciting new features! So, is it worth it…? YES! YES! YES!

Cannot Receive Email from Sender – DENIED_RDNS_MISSING

The sender mail server has no reverse DNS entry. You can verify the reverse DNS setting here: Check rDNS

The reverse DNS of your IP Address is typical of a dynamic/residential IP Address. Please have it updated to something unique like mail.example.com, or use the mail servers your ISP provides for residential customer traffic.

rDNS must be in the form of a fully-qualified domain name. rDNS containing in-addr.arpa are not acceptable, as these are merely placeholders for a valid PTR record. rDNS consisting of IP addresses are also not acceptable, as they do not correctly establish the relationship between domain and IP address.

rDNS that may be similar to dynamic IP space (containing pool, dhcp, dyn, etc.) may be treated as suspect, and should therefore should be changed to reflect a fully-qualified domain name with standard reverse DNS.

Multi year domain registration and renewal periods

Finally it is now possible to register .UK domain names for periods other than 2 years.

Since it’s inception, Nominet (the UK domain registry) have only facilitated 2 year domain name registrations and domain name renewals. It was not possible to register or renew for any other period. Unlike pretty much all other domain extensions which have since the year dot had registration and renewal options starting from 1  to 10 years.

We now support .UK domain name registration periods from 1 year to 10 years. Renewal periods of the same value are now also offered at time of renewal. You can see the official Nominet news release under Nominet to roll out multi-year reigstration periods for UK domains.

To get the best value from your domain name registration or renewal, go for 10 years (or as long as you can afford) as the price is stepped down and discounted for longer term registrations and renewals. Prices drop to as low as £2.99 per year if you register or renew for the longer periods, these terms are set and forget, no need to remember to renew.

Automatically scheduled 10 year renewal orders

Domains can be renewed up to 180 days before the expiry date. However this poses another problem which Nominet are aware of. That is, let say you have 100 days left on your domain name and you want to renew, you choose the 10 year renewal. Sounds ok? Well this will be a big fail. This is because a .UK domain name cannot have more than 10 years remaining. So in this case, if the renewal worked, you would have 10 years and 100 days remaining. No possible, so we automatically schedule your renewal order to execute on the expiry date – this resolves the (annoying) problem of timing your renewal perfectly.

How to delete files older than a specific number of minutes

Re: Use BASH to delete files older than so many minutes

When working with temporary files it is often good housekeeping to clear (delete) files older than a specific number of minutes. Use the following in bash command to achieve this goal:

# find /tmp/file* -type f -mmin +65 -delete

The above command will delete all files older than 65 minutes. Modify as appropriate.

MICROLITE4 IP Switchover (Migration)

Re: Network Migration of MICROLITE4 Server

We will be moving the MICROLITE4 hardware to a new higher performance network which will require a physical relocation and a number of IP address changes to the servers. This process will be completed automatically and no action from yourself is required. Apart from IP changes there will be no data configuration changes on the server.

The migration will take place on 2nd September 2012 between the hours 0900 – 1600

Unfortunately this means that there will be disruption to services during the migration, especially during the physical hardware relocation. We do apologise for this unavoidable disruption to services. We promise to keep the disruption period as short as possible.

Thank you for your patience during this mandatory migration period.
