In my position I often get to play with different sorts of hardware, but occasionally I get multiple of the same product to deploy. In these instances I have to become intimately familiar with the product so that I can best support users and manage deployments, both standard and non-standard. I’ve recently begun rolling out Dell Latitude e7470’s at Royal Holloway, and thought I would share some of what I’ve discovered. Continue reading “Dell Latitude e7470”
Following on from a rather old guide that I wrote about how to create a OS X Mountain Lion USB Stick, I thought I would share the latest method for creating a macOS Sierra USB Stick. Continue reading “Building an macOS Sierra USB Stick”
Apple launched macOS Sierra to the public on September 20th 2016
After being in Public Beta since July, macOS Sierra (10.12) was released on September 20th 2016 to the general public, and is now available as a free upgrade via the macOS App Store, however before you upgrade you may wish to check the following information to see if your software or hardware has compatibility issues, and to see if your Mac is supported.

So last week I updated one of my home servers from Ubuntu Server 14.04 to 16.04. During the upgrade a number of packages got upgraded, many of which I simply glossed over as the server was in a relatively vanilla state and the only service it’s running is Plex. openSSH was one such package that was upgraded, moving from v6.6 to v7.2 .
I completed my upgrade and tested Plex was working fine, and thought no more of it until a week or so later when I tried SSH’ing into my server only to be met with an error from PuTTY stating ‘Server Refused our Key’.
A bit of head-scratching and research later and I discovered that version 7.x of openSSH has made a change to deprecate DSA keypairs. It’s not a recent change, with articles appearing from February 2016, but with version 7.x of openSSH making it into stable distributions, it is worth highlighting before users upgrade their systems.

For those who purchased OS X Mountain Lion through the App Store and wanted to do a Fresh (Clean) install have probably come across many methods of creating OS X Mountain Lion Bootable USB sticks. The one I have previously used for installation of Lion and Mountain Lion on my home Macs has been the Lion DiskMaker. This software automates the creation of a Bootable Mountain Lion USB key (or CD) using a purchased and downloaded through the Apple App Store.
When I attempted to install Lion using the USB Key I created using Lion DiskMaker I discovered that during the installation I would be prompted to connect to the internet, and then to sign on to a Apple App Store account that has Mountain Lion already purchased (this holds true for installations of Lion too).
There is nothing wrong with this process, as it confirms that you have indeed purchased the software you are trying to install (a form of rudimentary DRM), and for home or single user environments this is perfectly acceptable. However, in certain larger environments (such as corporate networks devoid of central Apple Server infrastructure, or on secure networks), this process is untenable.

Adding a NetGear ReadyNAS Pro 4 Storage Array with 4x 2TB drives to handle all my digital asset storage requirements.
I have just purchased and installed a new Storage Array to handle a rather extensively growing photography (Digital Asset) library. Until now, the entire photography library was stored on a RAID 1 array on a Mac Pro (Mid 2010). Three weeks ago, that storage was filled. I had been aware of this for some time, so had to take action.
I analysed various forms of storage, including local, cloud, and distributed, however in the end I decided to go with a NAS. This allows for a centralised storage location which is simultaneously accessible from multiple computers, and includes redundancy in the form of RAID (Redundant Array of Inexpensive Disks).

With my recent experience of building two Core i5 systems on Asus Maximus III Extreme Motherboards still fresh in my mind, I thought I would impart some of the knowledge to the general community to help people with similar or identical setups.
