I have had a section called Philosophy on my very first website, and I have maintained a page called Principles or Our Approach ever since. It sounds as if those principles had been decreed at one point in time. As if aliens from outer space had dictated them.

However, I could simply say this: Since decades I play with technology, science, engineering, IT and everything in between. I worked in different industries. Each of them had good and bad aspects - regarding the actual subject matter and re the way of working. My main goal and hidden agenda was to every evolve but keep the good and interesting aspects of each of them. I could spin a story about how everything fits into a grand and big picture, and it is not even wrong.

But it's a good exercise to look at everything as disjointed pieces. At some point in your life that stories should speak for themselves. I am running my own business now for a long time; I don't have to explain and justify how everything fits together - as if it was part of a great plan.

In no particular order, and without aiming at completeness...

Like the Cobol mavericks at the turn the last millennium, I support legacy Windows Public Key Infrastructures. I have migrated them over and over and over. I don't pretend I know all the latest buzz words but it seems I can catch up quickly and connect the dots.

I am herding all the software tools related to sizing heat pump systems, related numerical simulations, and data analysis - the so-called Data Kraken. I could call myself a software developer - I use languages from VBA to C++, and I use pointers and recursion now and then. But I don't mind if somebody insists this on this being 'just scripting'.

I have been doing down-to-earth IT system administration for one small business - my second ever customer, loyal since more than two decades.

I get Ask-me-anything questions related to How Stuff Works and If That Stuff is Secure or If That Stuff Can Work at All. For some of that advice people even want to pay.

If you ask what real physics I actually use, I'd say Heat Conduction. Accidentally (?) it was one my specialties at the university, a long time ago.

I work mainly remote. It's more efficient, it's cheaper for clients, I don't have to travel, everybody is more focused. I don't do political projects (anymore).

I enjoy to find the pragmatic middle ground. I don't take as gospel: Software design patterns, methodologies, engineering standards, compliance guidelines, best practices, 'what everybody says', 'what everybody does just to be on the safe side'.

I believe in simple tools and dinosaur approaches. You can do project management with text files if you stick to the really necessary. I am wary of websites turning into little operating systems running on Javascript. I marvel at the explanatory power and elegance of textbooks from the last century like The C Programming Language or Landau/Lifshitz' Course of Theoretical Physics.

Taking stock of what I had done so far, I found that two things were part of all my endeavors: Teaching/training and software development. I have also been a student in parallel, most of the time. After I gave an academic lecture about PKI for a few years, I ditched formal teaching, and having completed another master's degree I also stopped collecting degrees and certificates.

Since a while I am catching up on computer science basics in self-study mode, and this year I have discovered the joys of pen-testing.

Happy Dinosaur

Best of 2017

(elkement. Last changed: 2017-12-14. Created: 2017-12-10. Tags: Life, Looking Back, Garden, Heat Pump, Introspection, Learning, Philosophy, Simulations, Thermodynamics, Work. German Version.)

I did not have ambitions 2017. It should have been a year of taking stock - and it was, in a good way.

  • I time-travelled and re-lived some history of software engineering, and finally learned basics of computer science. This was philosophical delight, but also useful and necessary: I was able to boost the performance of my simulations (above a level of what was, maybe, embarrassingly slow).
  • I tinkered a lot with numerical simulations of our heat pump system. Main thing I learned: The more modern the building, the more you'd need to simulate humans' behavior, rather than physics or control logic.
  • Reverse engineering and troubleshooting is what finally connects all the fields of science and engineering I love: Troubleshooting, ferreting out hidden causes and effects in hydraulics feel the same as sniffing and debugging software and networking protocols.
  • Theoretical physics reading: I returned to classical thermodynamics and statistical mechanics; I find it fascinating and beautiful in its own right, even if only at the pre-1960s level. I took stock of my writing on heat transport - and I am happy I can actually really use physics on a daily basis, in down-to-earth engineering projects.
  • I was thinking about automation, standardization, and big social media platforms. I struggled with this blog post about the future of small business for a long time, but optimism won. I might frame this even more positively today: There is a place for artisanal service delivery despite or because of Everything Being Offered As A Service by Omniscient Data Krakens.
  • My blog turned 5 in spring, and I allowed myself to return to a more philosophical blogging style (briefly). Otherwise, I finally and subconsciously made the elkement.blog my main resources of technical content - or at least content related to my professional domain, and content edited for clarity and entertainment. Whereas on elkement.subversiv.at I let my stream of consciousness flow. It seems that the pattern that finally emerges is: elkement.blog = elkement's tech / science magazine and platform for personal research news, with an ever growing focus on fields I have training in and daily practical exposure to. elkement.subversiv.at gravitates against the same focus, but I allow myself to focus on my personal perspective only. So here you find 'what I am doing with [insert: heat pumps, security,...]', over there you find the useful content as such.
  • Tomato harvest was great. I tried to grow late varieties - like Ox Heart - directly outside, and it worked.
  • Dinosaur Kale tastes good. And it is able to recover from a at attack of a bug that targets kale (and radishes' seed capsules). Don't try to keep seeds of radishes in the land of canola.

This website is an old-school non-interactive site. My blog technically isn't, but looks like one now, for the lack of visible comments. However, messages have reached over covert 1:1 channels, so I do now that there is a small but sincerely interested group of readers. I thank you all for reading my stuff!

Cheers!

My Philosophy (?)

(elkement. Last changed: 2016-05-02. Created: 2016-05-01. Tags: Learning, Life, Looking Back, Meaning, Philosophy, Profession, Technology, Work. German Version.)

Once upon a time this category was intended to comprise what I had learned about philosophy. I had even aspired to study philosophy. Then came the dawn of the web and of unconventional philosophers of web culture.
I had also followed common wisdom, and my first FrontPage-generated business website had a section called Philosophy.

What's left of that, or what has been my conclusion?

I believe - in a pang of cheeky self-assurance - that I ought to have my own philosophy. Experience, business and otherwise, should be good for something. My philosophy does not focus on the grand questions of life. I might have had an argument with my former self, the idealistic student of science who aspired to change the world as a physicist, a profession I pictured as a cross-over of hands-on MacGyver theorist-philosopher-mathematician, ad-hoc-inventing smart tools whole mulling upon deep insights on universe and everything.

The unexciting truth is that my personal philosophy is explained best by summing up the different roles I have ever seen myself to take on, no matter what my job title was. None of them was about making profound changes to the world or being any sort of thought leader.

1) The Reverse Engineer

I have been told that I dismantled (tech) stuff already at a time I have no conscious memory of. I wanted to know how things worked, and I found a way to get there. Some of these activities morphed into a career later, the obvious one having been IT Security - the stereotype field for lone maverick nerdswho reverse engineer stuff. Even as a white hat hacker and so-called security consultant you have to indulge in the relentless black hacker's mindset - or you become a security bureaucrat, ticking off checklists and following rules. (Which dies not mean you should not know the rules).
But I could as well have turned into a tax advisor or lawyer, given my pleasure in finding out how such systems work.

I disagree with Keep To Your Core Skills, and I have often used 'wasted my precious time' by 'not delegating'. I hope or believe - delusionally - that 'actually' everybody has this pleasure of finding things out ((c) Richard Feynman). I am wary of marketing (tech) stuff to allegedly dumb or stressed out end-users who don't want to understand anything about underlying technology. Perhaps I am talking to less than 10% of people, but after all this is about my personal credo.

2) The Mediator

One of my first ever fantasies as a child that came close to something like a career was being kind of a negotiator or diplomat. I am not kidding: I dreamt about settling peace treaties between Mickey Mouse and his sinister opponents in his cartoon world.
This has impacted any of my jobs, but it finally surfaced expicitly when a client booked me 'for another mediation', which was in fact the follow-up of a very technical meeting.

I had considered yet another training or degree, in coaching, psychology, or the like. However, I am glad that I never left technology for good (see 1). There is a paradox: People want such 'tech project psychology' services. However, they will not buy it if labelled as such yet happily use them if they come as a hidden by-product of technical consulting.

3) The Communicator

Maybe principles 1) and 2) can only co-exist if you bridge them with a lot of talking. During most of my career 'teaching', 'training', or 'lecturing' had been part of my official duties or a side-project done in moon-lighting fachion. I stopped teaching when I became a moonlightung student again. I have also realized that I am not cut out for over well managed, structured, quality-assured educational systems. I suck at keeping to my own agenda, and I beg for being carried away by hard off-script questions.
I was not the best class-room teacher, but I think I was good at informal, jam-session-style train-the-experts sessions.

Projects I remember most fondly were those where clients were not only interested in The Tech Guy Who Will Fix Everything but also in my pontifiating on fundamentals, even if that was not required to get the job done. But as I said above (1) - I believe it's always worth it.

4) The Organizer and Automator

When I was a child, I was not called upon to tidy up my room: Not only was I self-motivation to clean it - Mr.Monk-style - but I rather re-organized my cabinets quite frequently. It was Feng Shui of Decluttering meeting obsession with structure, and it has not changed to this day.

I have extended these principles to the virtual world as soon as I had 'data'. Writing a tool, script, program to automate something is second nature. Some sort of software development has always been part of my jobs - just as teaching was, but I found out only recently that I like data analysis and programming much more.

Proficiency with interpreting and manipulating data, and with using or fixing software is part of our culture and should be trained and valued just as other basic technologies and skills. And of course I believe that we, each of us, really needs them! But perhaps it is just my bad luck or my high standards... Every time I just to use and application or service as a normal end-user I end up with low-level troubleshooting.

 

I am aware of the picture of the obsessed nerd that I have painted here. I don't underestimate subtleties and human nature though. But nowadays soft skills are so often praised to the skies and people with 'big ideas', rather than nitpicking detailed persons, so as Subversive Element the contrarian stance comes natural to me. Even the most empathic coach who tells burnt out IT guys not ot overdo perferctiomism will be very happy if a neuro-surgeon or airplane engineer are totally obsessed with flawless technology.

On the impact of physics on my life

(elkement. Created: 2016-03-12. Tags: Looking Back, Physics, Science Communications, Technology, Theoretical Physics, Troubleshooting, Work. German Version.)

I renamed my blog elkement.wordpress.com last November:

Theory and Practice of Trying to Combine Just Anything

became

elkemental Force

The original tagline was

Physics versus engineering
off-the-wall geek humor versus existential questions
IT versus the real thing
corporate world's strangeness versus small business entrepreneur's microcosmos, knowledge worker's connectedness
versus striving for independence.

until it became

I mean it

and finally turned into

Research Notes on Energy, Software, Life, the Universe, and Everything

This means that my blog elkement.wordpress.com has found its purpose, and I am able to distinguish blogging better from publishing to this website elkement.subversiv.at. My actual research and 'science writing' is featured on my blog. Over there I am using wordpress.com features I have no desire for developing them myself for - and this website will remain my 100% home-grown self-developed pseudo-blog with a very limited feature set and no interactivity. The blog has LaTex support and allows me to present galleries of technical figures and diagrams.

These recent blog articles showcase what elkemental Force has been and is covering now (the end of a journey that started already two years ago - when heat pumps and thermodynamics replaced quantum physics):

Rowboats, Laser Pulses, and Heat Energy (Boring Title: Dimensional Analysis)
How Does It Work? (The Heat Pump System, That Is)
Half a Year of Solar Power and Smart Metering

My personal website, on the other hand, should be just this: A more self-indulgent site that provides status updates, meta-information and About-Me-style summaries. Because of that I will keep not sharing articles here to any social network.

And so yes: The hands-on engineering, physics, math and data analysis will be done over there on the blog. But there really are personal meta-thoughts on physics - so I don't have to change categories here.

(Theoretical) Physics and Me

Over the Christmas holidays I have been nearly offline from social media. I used the internet as I believe it was intended for me: To learn about something in depth and not necessarily sharing my insights or my 'progress'. I indulged in theoretical physics lectures just for the joys of it. I can rationalize: Yes, a bit of mathy gymnastics also serves me well when I deal with more mundane physics as a professional - such as toying with the heat transport equation.

But the real reason is unrelated to work: Theoretical physics and mathematical modelling of a small part of a complex world gives me the pleasure - and/or the illusion - of being able to understand and solve, well, something. Whenever I had been very stressed out in the past, close to burn-out, I got up even earlier - as 4:00 AM sometimes - to plow through Feynman's Physics Lectures or my favorite German volumes of theoretical physics by my late professor, W. Macke.

Not only did it help me to focus onto abstract details of a logical clear universe and to enter a more detached state of mind, but amazingly it also made me work more efficiently and focused later - on whatever technical challenge I had to solve. In those days, I was mainly concerned with Public Key Infrastructure, networking security, and applied cryptography.

With hindsight - and hopefully not too much hindsight bias - I feel that a rigorous training in a mathy subject boosts your results in any endeavor that needs an analytical approach. Perhaps only your physics training makes your realize that you need a more analytical approach at all, in addition to soft skills, practice, and familiarity with culture in certain industry sectors. I am thinking about project management, for example.

I believe that in any 'STEM' job, e.g. in IT, it is soothing to re-learn fundamentals often. One should know more than seems necessary about 'theory', before or in addition to knowing how to google, where to look up things, or whom of your tech buddies to call. Success in technical troubleshooting always gave me most contentment when I was doing it in my head mainly - like walking through a networking protocol the way it was designed, comparing that to messing reality, and uttering an educated guess about the root cause of an issue which was finally correct.

Whenever I had been blogging about a field of physics not related to my work - like quantum field theory - it was these mental connections I had in mind. I was trying to convey the joys of physics, but my main focus was different from most science writers' ones, so I think my writing was not engaging enough for the interested lay audience and sometimes oblique owing to too much references to math (whereas it was very basic for experts, of course).

My science writing is often a covert and feeble attempt to encourage others to tackle the real thing, that is the fundamentals and the math, and then to feel the same effects. I have seen that more books seem to have been released recently that try to bridge this gap between classical science writing (following the mantra of: Every formula will half readers) and text books.

I want to be part of that movement.

Not much happened in 2015

(elkement. Created: 2016-01-11. Tags: Edible Wildflowers, Administration, Garden, House, Infrastructure, Life, Looking Back, Nostalgia, Photovoltaics, Projects, Remote Work, Work. German Version.)

The most existing things, in no particular order:

Infrastructure updates - 'real'

Solar panels, before installation

Infrastructure updates - 'virtual'

  • We migrated three bank accounts, and I learned what I never wanted to know about different ways to setup debit orders. My favorite: an anonymous form on the vendor's website. Security = knowing your client account
  • Our village has changed its zip code. I learned what I never wanted to know about how organizations store addresses. Goodie: Opening 'support tickets' turned interactions with big platforms into something human.

Work and Life
