Recently I have been interviewing and it is eye opening to be the other side of the interview table/Zoom chat! Having been an iOS developer for 14+ years, I think there are things you learn very early on in your career that you never question or need to revisit it again and it can catch you a little off-guard. One of those areas that I got asked about recently was about the relationship between the frame, bounds and transforms in a `UIView`.
New Mac App – Text Calculator is live
2020 was a hectic year and somehow I didn’t manage to post on my blog, however I was hard at work finishing some of my side projects. One such side project has now been approved and is live in the Mac App Store – Text Calculator.
A guide to learning how to 3D Print
One of the latest trends that does not show any sign of fizzling out yet is 3D printing. The technology isn’t mainstream enough for everyone to have a 3D printer but I’ve had many interested people when talking about the things I’ve printed. Surprisingly squirting melted plastic through a hot-end and getting a good print is hard and is more of an art form. Here are some of my learnings and tips on 3D printing.

Making a Psion Series 3a/c/mx USB power cable
After my previous success recovering data from my old Psion Series 3a palmtop, I decided I needed to bring some of the cables into the 21st century. While batteries usually last weeks with the Psion, using it on my desk was frustrating as it powered down after 5 minutes to save battery power. Therefore I decided the first cable to work on was the mains adapter and what better way to update it than make it a slim ultra-portable cable powered by USB – I could then use USB wall plugs, my MacBook Pro or even a humble USB power bank to power my Psion. Time to get out my wire snippers and wait for the soldering iron to warm up!

Psion Fever – Breaching a digital data island
I recently decided to dig out my old Psion 3a palmtop from a storage box at home and I’ve been somewhat obsessed with it lately. When deciding to chuck something away, the tidy- living guru Marie Condo asks “Does it spark joy?”. So I looked at my 25-year-old obsolete Psion and thought yes… Yes it does, it sparks considerable joy.
Ahead of its time
The Psion was way ahead of its time with many features that the iPhone has only just recently received in the last 5 years or so. Features such as copy & paste, file management, printing, multi-tasking and all powered by 2 AA batteries! Something that is incredibly refreshing is the flexibility of the OS – just about anything can be tweaked with a specially written Assembly driver which is a huge contrast to the iron-clad security of iOS. This flexibility might also just be its salvation from an e-waste recycling future.
