Whether you agree with Myers-Briggs personality profiling or not, like fellow BBC’er Ian Forrester I have found them a useful frame of reference from which to discuss my personality, because I see similarities between my perception of me, and the classification.
I took the Myers-Briggs personality profiling, and it has labelled me on several occasions an INTP:
INTPs are marked by a quiet, stoic, modest, and aloof exterior that masks strong creativity and enthusiasm for novel possibilities. Their weaknesses include poor organization, insensitivity to social niceties, and a tendency to get lost in abstractions. Keirsey referred to INTPs as Architects, one of the four types belonging to the temperament he called the Rationals
I – Introversion preferred to extraversion: INTPs tend to be quiet and reserved. They generally prefer interacting with a few close friends rather than a wide circle of acquaintances, and they expend energy in social situations (whereas extraverts gain energy).
Is this bad news for me? Introversion can be seen as a negative in today’s hyper-communicative world, especially for a team-based work environment. However I don’t think it need be a problem in an organisation that prioritises abstract thinking and creativity, because introverts are often very strong in both. The technology and R&D side of the BBC, I would argue, is such an organisation.
I know a few people from Imperial College London, one of the top universities in the world for Computer Science (and Science Technology Engineering and Medicine in general) and have found it full of technically gifted introverts. Now, I didn’t go to Imperial myself, but it does seem that there is a correlation between introversion and high amounts of technical ability. I have found this also with a lot of software engineers that I have worked with.
I am not saying necessarily that all good software engineers are extreme introverts, in fact I would say that this is untrue in a number of cases. This is because Agile software engineering often uses techniques such as pair programming from Extreme Programming, and it helps to have extroversion when dealing with hyper-social practices such as programming as a pair every day all day (which I have done, and found it very draining).
In fact, I have noticed that technical ability is less important than your ability to work in a team at the BBC. I generally have fairly good social skills and tend to like introverts so I personally have not had a problem with dealing with people who were very introverted but were technically quite brilliant. However it was clear that these types of people just didn’t seem to fit in quite as well in BBC teams with high collaboration aspects. I think this may be down to cultural fit rather than something we can extrapolate over all software engineering organisations.
Indeed, aside from my anecdotal evidence, in the book ‘Making Software’ Jo E. Hannay analyses the academic research on what type of personality programmers have, and what effect this has on their work. She writes;
We found that programmers deviated from a reference group in that they are lower on Extraversion, lower on Emotional Stability, and higher on Openness to Experience [Hannay et al. 2010]. See also [Moore 1991], [Smith 1989], [Woodruff 1979], [Capretz 2003], and [Turley and Bieman 1995] for related results. Programmers are also more homogeneous than the population as a whole; that is, programmers vary less in personality than do people in general.
So programmers tend to be introverts. Not really hugely suprising is it? However, she also notes:
We investigated .. in the context of 198 professional programmers pair programming over one day [Hannay et al. 2010]. We found that personality was a weak predictor of pair programming performance. Even crude measures of expertise, task complexity, and even the country in which the programmers where employed had greater predictive power than personality. The study also included an analysis of personality on individual programming and whether the effect on performance of pairing up had anything to do with personality. Again, expertise and task complexity are stronger predictors than personality.
Therefore an introverted personality is a poor predictor of pair programming performance across the industry. She goes on to say:
In ethnographic studies focusing on personality issues and disruption in software engineering team collaboration, it was found that disruption is bad, but lack of debate (which is a mild form of disruption) is worse [Karn and Cowling 2006], [Karn and Cowling 2005]. It is argued that pairs or teams with personalities that are too alike will lead to lack of debate. This finds empirical confirmation in [Williams et al. 2006] and [Walle and Hannay 2009]. In particular, differences in Extraversion has the largest effect: pairs whose peers have different levels of Extraversion collaborate more intensely (that is, engage in more discussion) than those with more similar levels.
She is saying that a pair of extroverted and introverted personalities collaborate more strongly than a homogenous pair. To me, this is good evidence that introversion and extroversion have their place in modern software development teams across the industry, and both types of personality should be culturally valued for collaboration, not just extroverts, even at hyper-collaborative organisations such as the BBC.
I’ve finished my 6U Eurorack case. It took me 9 months to build, buying a couple of modules a month.
I wanted to make a self-contained dual voice synthesizer that would interface with my 2x Doepfer Dark Energy MK1s and my Microbrute, on a budget. I also wanted to add some random sound generation features.
I chose to make the synthesizer out of Doepfer modules because they are easy to find cheap second-hand, and also because they are well-engineered. (If they’re good enough for Kraftwerk, who am I to complain?)
Oscillators and Sound Generation
- 2x standard Doepfer A-110-1 VCOs with pulse-width modulation. I am no expert, but find these oscillators sound good enough for the money.
- A-118 Random Noise module, which outputs white and coloured noise. This has been useful for adding noise to a patch, as well as feeding the random noise generator through the quantizer and S&H modules for interesting random effects.
LFOs and Envelopes
- A-143-3 Quad LFO, which has been very useful in modulating my external gear, such as my Microbrute and Doepfer Dark Energy synths. I find it’s a good utility module to just patch something up for modulation, even though I rarely find myself using all 4 LFOs at once.
- A-145 LFO – I actually find myself wishing this was a VCLFO so that I could make midi-synced LFO sweeps, and might replace it with one eventually. I like the reset feature though.
- 2x A-140 ADSR – Standard envelopes, I bought two so I can modulate the VCA and filter separately at the same time, as is standard in synthesizers.
Mixers and VCAs
- A-132-3 Dual VCA – Another standard module, this is particularly useful as it has two VCAs, so I can feed each oscillator into its own separate VCA. I would like another one of these so I could amplify the output of the noise module separately from the VCOs.
- 2x A-138 Exponential Mixers – I have two so I can mix multiple waveforms from the VCOs with the white noise output from my noise generator module. The mixer in the bottom right corner of the case has rubber no-slip knobs, and I use it for the main output from my synth.
Quantizer and S&H
- A-156 Dual Quantizer – This is a really fun module which I use with LFOs, envelopes and my noise generator to make musical sounds from non-musical sources. I think it will come into its own when I get the Make Noise Maths module, which is on my ‘next steps’ list.
- A-148 Dual Sample & Hold – This is a module I haven’t quite grasped the utility of yet, I currently use it wired up to filters and a LFO for S&H filter effects.
I love filters.. so I got quite a few!
- A-120 VCF1 Low Pass Filter (Moog style) – The standard moogy filter, nothing wrong with it. I like the sound but mostly use it for filter sweeps.
- A-127 Triple Voltage Controlled Resonance Filter with Breakout Box – This is the key element of my setup. It allows for some really nice multiple filter chaining effects. I have the top filter set to ‘Low Pass’ mode, and the second and third filters set to ‘Band pass’ mode. Since I already have a LP filter in the Moog style A-120 I may change this back so it becomes a triple BP filter, which is the default. You can make some really nice patches with the inbuilt LFOs modulating the filter sweeps, but usually I will wire it up to my Quad LFO for modulation. As a unit, it is really good at making vowel-like sounds for eerie ‘almost human voice’ effects. The breakout box, which I haven’t soldered in yet, so haven’t actually used, will expand the possibilities of the unit even more, allowing me to put separate filers on each oscillator, for example. Love this module.
- A-106-1 Xtreme Filter – I haven’t used this much yet, but I just had to have the MS-20 style LP/HP filter in my case, and this filter ticks all the boxes.
MIDI Interface and Multiples
- Kenton Pro Solo MIDI-to-CV interface – I use this with my computer, allowing me to send CV for the oscillators through the Intelligel Buff Mult. It has clock out and a bunch of different features, such as portamento and even a LFO.
- Intelligel ‘Buff Mult’ – My only non-Doepfer module. This is a buffered multiplier, meant to make sure that fast pitch changes are duplicated correctly over the oscillators. I also wire up my Doepfer Dark Energy Mk1s to this, so I can have 4 oscillators playing at once.
- A180-1 Multipler – Just a standard multiplier which I use because I don’t use stackable cables (can’t afford them).
Some things I have been meaning to investigate in my own time, but haven’t, because life just gets in the way.
- Music Theory
– It might surprise a few people that, as a software developer, I never took maths to A-level. I picked up a bit of maths in my CS degree, but I never really got a firm grounding in it. This has prevented me from understanding and coding advanced stuff in game development, understanding audio to a decent level, and generally doing things in which I consider the more interesting fields of computing.
– I have been getting better at playing the piano/keyboard by ear, but I have never fully learned to read music, and I would like to.
– I would love to be able to build simple DIY synthesiser module kits for my Eurorack setup. I imagine I’d have to start on something small though.
It would be great if I could take courses in these subjects, via the OU or something similar. I just have to find the time.
Now that I am midway through the year, I thought I’d revisit the goals I set myself at the start of the year, to see what has changed.
- Settle into my new role at the BBC as Test Manager – I suppose this has not been achieved. I will have more updates soon (hopefully) but a change of direction is likely to happen.
- Pushing for a place to be opened up in Platform Test to employ someone from the Extend Scheme – This has been achieved, and someone will be joining Platform Test from the Extend scheme in October, I’m happy to say.
- Get better at music production – This has been achieved. I have been working with my friend I will call ‘G’, which has massively improved my production skills. I have posted music that I see as much better to Soundcloud.
- Getting married – Well.. things didn’t work out with that. But I have a new girlfriend who will hopefully be moving to live with me, so things seem to be recovering there.
- Making friends with more people that share the same interests – Partly achieved. G is a good example of someone that I have met through looking for friends with the same interest.
- Saving more over the course of the year – Partly achieved. I have bought a house, so now I am in a quite a bit of debt, but the money I will be putting towards my mortgage will be money I am effectively ‘saving’ because it will be put into the value of the house.
- Joining a pension scheme – Achieved.
- Adopt a regular form of keeping fit – Not achieved. I have a gym even closer to where I live, 5 minutes walk, so hopefully I will use it more soon. It is difficult for me, as the medication I’m on makes me feel tired all the time, but they do say that exercise improves energy levels.
Although I’ve achieved the majority of my goals, I haven’t achieved two of the major goals – around my job and around exercise, which are both things I need to work on. There is still time left this year to make a difference in these areas.
