Tesco Mobile add Personal Hotspot for iPhone after 3 years

April 27th, 2014

The option to share internet access through your mobile data connection (3G or 4G) from your phone to a laptop, tablet or other device is now know as tethering (for those with long enough memories it was called a “data modem” in the Ericsson T39 days but worked via a cable rather than with WiFi).

With the Apple iPhone the ability to tether (worked on iPhoneOS 3) is now known as Personal Hotspot (introduced in March 2011) as the internet connection from the mobile data contract is shared by WiFi.  In iOS 7.1 the use of tethering has been tightened up by Apple. However, this feature can be disabled by the mobile phone carrier as was the case with Tesco Mobile when iOS4.3 introduced the feature.  The Tesco Mobile website FAQ stated for several years that they were working on adding the feature.  With iOS 7.1 Tesco Mobile have added the Personal Hotspot feature to the iPhone.

Configure a Virtual Private Server (VPS) for a Virtual Private Network (VPN)

October 12th, 2013

I purchased a years worth of Virtual Private Server (VPS) from httpzoom.com for the purpose of setting up a Virtual Private Network (VPN).

The VPS costs £12/year and comes with 500GB bandwidth.  It runs CentOS and I installed a PPTP server to connect iPhones, iPads and Macs through the VPN.  I will look to add OpenVPN later and a method of supporting Apple TV and PS3 in the future.  I soon leart that I needed to protect the server somewhat better on the internet so I installed fail2ban on CentOS to protect from bot hacking attempts.

La Fonera hack for Raspberry Pi network connectivity

September 10th, 2013

Adding a Wi-Fi router to a Raspberry Pi to provide wireless connectivity but through the ethernet port rather than by a USB dongle.

The La Fonera 2100A/B/C routers were given away for free by Fon to grow the number of Fon Wi-FI Hotspots.

You need to put DD-WRT onto the router but first you need to hack La Fonera to get at the firmware.  Enabling SSH access on a La Fonera 2100A/B/C.

CalendarAgent error in OS X Console for Google Calendar

August 24th, 2013

On viewing the Console in OS X I discovered I was getting lots of CalendarAgent errors:

CalendarAgent[437]: AOSKit ERROR: (-) RAF: Invalid url -- https://<username>%40gmail.com@www.google.com/calendar/dav/<username>%40gmail.com/

It turns out that a bug in the Mail, Contacts & Calendars section of System Preferences causes a Google Calendar to be misconfigured.

Punnet for Raspberry Pi

The Punnet is a cardboard case for the Raspberry Pi that you can print yourself from the PDF and cut out.  You can print to paper and then glue that onto card if your printer isn’t really up to it.

 

Inspired by the Fusion Drive

June 30th, 2013

Apple Fusion Drive

Adding an additional SSD to OS X and retaining the original HDD in a MacBook Pro.

By adding a small SSD to OS X congaing the Operating System and Applications an increase in performance can be achieved. Boot times can drop by as much as 50% when compared with a standard 5400 RPM HDD as fitted to a MacBook Pro.

A 64GB SSD can hold OS X Mountain Lion and a reasonable sized Applications folder. However, it is not a suitable size to hold much user data in terms of photos, music and films. Retaining the internal HDD of 750GB allows all that information to be stored on the slower but larger volume.  A MacBook Pro with an SSD and HDD performs much like the new Apple Fusion Drive but without the dynamic data tiering.  Moving the OS X Users folder to the SSD from the HDD may be required due to space constraints.

Clone the HDD to the SSD and then use the old User folder on the HDD.
