This book is probably about a very different kind of ”engineering” than what you had in mind, but it’s been highly influential to my thinking:

“The Social Construction of Reality: A Treatise in the Sociology of Knowledge.” Berger & Luckmann 1966.

Perhaps the core insight to me is that not only does every practice of engineering exist as embedded in the context of a socially constructed reality, but the practice of engineering itself also fundamentally involves the continual construction of such realities. In other words, for a software engineer to be able to do their job, they must among other things be a kind of applied social epistemologist.

I expect this framing doesn’t make much sense to many readers — I’m hoping the following articles might serve to illustrate:

“Programming as Theory Building.” Peter Naur, Microprocessing and Microprogramming 1985 (https://doi.org/10.1016/0165-6074(85)90032-8)

> … suggests that programming properly should be regarded as an activity by which the programmers form or achieve a certain kind of insight, a theory, of the matters at hand. This suggestion is in contrast to what appears to be a more common notion, that programming should be regarded as a production of a program and certain other texts.

“Interpretation, Interaction and Reality Construction in Software Engineering: An Explanatory Model.” Kari Rönkkö, Information and Software Technology 2007 (https://doi.org/10.1016/j.infsof.2007.02.014)

> Floyd’s paper Outline of a Paradigm Change in Software Engineering requested that we move from a product oriented paradigm to a process oriented paradigm.

> Naur’s paper Programming as Theory Building made it painfully clear to us that exemplary resources in the form of material and available support are not enough when modifying others’ programs. In fact, if Floyd’s claims had been taken seriously by the software developers in Naur’s study, and if the same developers had access to an explanatory model … their difficulties could have been both anticipated and prevented.

> This article … explains from a natural language point of view, how interpretation takes place, and discusses the consequences of this in relation to interaction and reality construction in software engineering practice.

Research citation & abstract, for other PDF-challenged individuals:

Braddy, Jon. “Utilizing the Octothorpe (#).” Exchanges: The Interdisciplinary Research Journal, April 2022. https://doi.org/10.31273/eirj.v9i2.837.

”Felix Guattari’s ‘Schizoanalytic Cartographies’ acts as a methodological blueprint and can be used to explain a subject’s lack of expressivity when confronted by Foucauldian systems of discipline and punishment. Understanding mechanisms of regulation and control within a closed or open system is the purpose of cybernetics. This communication studies tradition emerged from the artificial intelligence work of Norbert Wiener’s data flows with the intentional purpose of steering people, thought, societies, and the cosmos towards—becoming. Using the analogy of the octothorpe (#) as a roadmap explaining the four cartographies (Flows, Phyla, Territories, Universes) as outlined by Guattari, this manuscript will analyze the film, ‘War Games,’ demonstrating schizoanalytic technique. Another layer of power over humanity is not a panacea, rather it ushers forth civilisation’s speedier, and predicted, demise.”

From the comments here, I was expecting to find myself hopelessly out of date, and to end up with a migraine trying to parse through a mindnumbing list of changes. Turned out I was mistaken.

  > Me: oh, cool, they fixed so many tiny things I had bumped up against
  > Some others: oh no, why are things changing
I'm not getting it. Maybe I'm reading this wrong, but to me these seem pretty obvious small issues to smooth over.

Perhaps not many in this audience are dealing with having to mitigate the prospect of dementia. How about something close to the horizon for almost all of us?

> Vitamin D deficiency can cause over‐activation of the pulmonary renin‐angiotensin system (RAS) leading to the respiratory syndrome. RAS is regulated in part at least by angiotensin‐converting enzyme 2 (ACE2), which also acts as a primary receptor for SARS‐CoV‐2 entry into the cells. Hence, vitamin D deficiency can exacerbate COVID‐19, via its effects on ACE2.

— Vitamin D and COVID-19: Role of ACE2, age, gender, and ethnicity. J Med Virol. 2021 https://pubmed.ncbi.nlm.nih.gov/33990955/

> Angiotensin-converting enzyme 2 (ACE2), a part of the renin-angiotensin system (RAS), serves as the major entry point into cells for SARS-CoV-2 which attaches to human ACE2, thereby reducing the expression of ACE2 and causing lung injury and pneumonia. Vitamin D, a fat-soluble-vitamin, is a negative endocrine RAS modulator and inhibits renin expression and generation… Therefore, targeting the unbalanced RAS and ACE2 down-regulation with vitamin D in SARS-CoV-2 infection is a potential therapeutic approach to combat COVID-19.

— A brief review of interplay between vitamin D and angiotensin-converting enzyme 2: Implications for a potential treatment for COVID-19. Rev Med Virol. 2020 https://pubmed.ncbi.nlm.nih.gov/32584474/

Here’s a caveat to remember when taking vitamin D:

> Majority of the adults are deficient in both vitamin D and magnesium but continue to go unrecognized … Mg is essential in the metabolism of vitamin D, and taking large doses of vitamin D can induce severe depletion of Mg. Adequate magnesium supplementation should be considered as an important aspect of vitamin D therapy.

FWIW, I think the article agrees.

> vitamin D effects were significantly greater in females versus males and in normal cognition versus mild cognitive impairment.

> vitamin D effects were significantly greater in apolipoprotein E ε4 non-carriers versus carriers.

Translation: If you’re already cognitively impaired, vitamin D can do little to fix that. Same goes for if you’re at high risk for Alzheimer’s genetically (ApoEε4), or generally at higher risk for neurovascular diseases (male).

However, as I’m sure others in the comments will point out — supplementing vitamin D will at least ensure you’re not getting cognitive impairment due to vitamin D deficiency, which seems to absolutely be a thing.

Great information & a good summary, thank you! If I’m looking to get more in-depth with the known mechanisms of locus coeruleus and episodic memory, would you be able to recommend any sources of yours?

To try and tickle your interest, here’s why I’m looking into it: I have no episodic memory. I have aphantasia. I have hypotheses for explanations that I’m looking to correlate with different pieces of research, and locus coeruleus interactions is one area I have yet to look sufficiently deeply into.

I do often share this sentiment, even if I’m not in agreement with your tone. But I’m curious —

  > Specific qualia have a higher cortical resonance, due to overarching reinforcement over time, and they are picked out.  
  > The more a single stream of information is focused on, the greater degree of resonance that may occur with less endowed qualia (slow down, notice more shit due to neuro-satiation).
How did you come upon these conclusions, or this framing? I’m surprised, because what you’re saying meshes well with some details of a model for the neurophysiological basis of conscious experience I’ve been working on… and I don’t think I’ve ever seen anyone else point out these exact connections before.

For all I know this could be general knowledge in some community; or something believed widely at one time, now discredited. I’m operating in a vacuum and have been putting things together from what to me appear to be first principles. I might be reconstructing common knowledge, or just unknowingly restating things I’ve unconsciously absorbed in the past… The potential for which bothers me now that I’m seeing your comment.

Where’s your perspective coming from? :) Pointers to your sources would be much appreciated.

Oh, this was a new one for me.

In case you like narrow but Victor’s not your thing, I can enthusiastically point you towards Iosevka. (That’s also available in Victor’s comparison picker. Nice!)

> the compact camera market is dying. > Olympus just sold off their camera division.

And someone _bought_ that camera division. With the intent to continue designing, manufacturing and selling cameras under the Olympus brand. Sure, Olympus wasn’t doing great, but someone paid money because they thought they could run the business better. And their consumer business is in selling compact cameras, right? There appears to be at least some faith in the market.

> We probably won't see many new models from Canon

Personally I sure hope so. Their less-than-full-frame offering has been pretty lackluster afaict, other companies are doing the job better. We’ve lately seen some surprisingly kickass tech innovation in the full frame market from Canon, though. I hope they continue to focus their efforts.
