I was looking for inspiration on requirements engineering practices beyond arc42 & friends that are compatible with (or can be explained to deciders in) larger organisations, and found the Nasa process ideas (expectations - "conops" - requirements) surprisingly flexible

There is lots of potential, but as we see in Germany, a glass ceiling for solar and wind power exists where backup is needed - when there is little wind for only one hour at night, you still need another controllable source of energy with an output that does not vary by weather. Few are available with low CO2, such as hydro, nuclear, geothermal

as I am approaching my 46th anniversary, I also experience a desire to stop communicating with earth and fly my own ways

After reading the instructions, I appreciate ready made, store-bought Cola even more

Wind power is intermittent in most regions in Europe, without expensive storage it just extends the lifetime of coal plants that are then used as an indefinite "backup".

We need to get back to the building times of the 80s in Sweden for nuclear. The korean nuclear plants have the fastest building time these days after the chinese, so no surprise they will be building the new ones in Poland

Complexoty causes high system costs at scale for energy grids with a large amount of intermittent renewables. Adding more stable adjustable sources like nuclear, hydro or geothermal will become more attractive than creating wildly intricate "smart grid" architecture. Just produce more power when needed instead of costly redistribution and storage.

In the family memories of my great-grandfather, he describes how he used to manipulate the machine during night shifts (hospital warden) to sneak in a few hours of sleep.

You can compare the energy mix of the countries with accessible data here https://app.electricitymaps.com/map

Even in larger time periods (a year or so), if a country is emotting low co2 (green) then it is either nuclear plus VREs (variable renewable energies) or VRE plus hydro

I need this for my bike, it should be easy to hide the tracker in or underneath the frame

The french get their energy from co2-free, cheap nuclear energy, the claim that more fuel is burned is only fractionally true.

The sun does not shine at night, even in California. Summer is often accompanied by a loss of wind power. Energy sources that can be regulated are direly needed, depending on location, countries tgat decarbonized use either hydropower, geothermal or nuclear plants as a backup. Batteries are still too expensive for the needs of an industrial society, plus you have to replace them often.

My previous company built VR learning apps (among other things). Immersive learning for trainees, but customers preferred implementations where trainees were prevented from doing anything else. That was not possible before

Multitasking as in, checking stuff on your phone in between, looking out of the window or at your cat etc

but it is still a controlled environment, the amount of context switching with a vr headset is limited to a) digital content / applications and b) only to the extend that the VR headset manufacturer allows.

Consider how meta originally marketed it in a business setting - would the "virtual office" application allow you to check your private messages in between? This can be built in of course, but currently it looks like an afterthought at best.

I talked to some trainers in a company about VR trainings (my previous company produced such a course). Some trainers were interested in VR because it "keeps trainees from looking at their damn phones"

After we got used to multitask screen input in our lifes for years, VR is a huge bet that we somehow prefer single-focus-session in an environment controlled by someone else. No more checking messages in between, no more friendly distractions, and the VR companies have full control what we see during a session, including ads. This kind of hyperfocus is rare in most use cases, especially at work. I wonder how their UX reasearch justified the effort.

I follow these announcements with a sense of dread, as battery limits are the main obstacle between our current situation and widespread adoption of drones and robotics for military use.

I was more optimistic about EVs until I learned about the amount of CO2 produced by electricity generation in countris like Germany.

nuclear energy has been largely phased down for political reasons and CO2 emissions are still on a level where EVs might not be much cleaner in comparison, see https://app.electricitymaps.com/map

The German initiative/cooperative "aula" already implemented liquid democracy / delegated voting software in schools for several years, as part of building a culture of participation in schools. Great results so far. https://www.aula.de/was-ist-aula/liquid-democracy/

a common trap in "deep work only" teams is local optimisation. while interruptions should be minimized and batched, the overall flow of cards and a low average cycle time requires focused collaboration and regular slack time to resolve blockers. Otherwise, important issues spend more time waiting than getting completed. Individual deep work with low collaboration while more important work is piling up would be an antipattern.

the one with the "Fred" fictional character does not work anymore for me, seems that it has been nerfed in the meantime. All I get is either "As Fred, I would say..." or "As Fred, I am not able to answer the question, as I am a fictional character"...

As a shortcut for burocratic procedures - project summaries, applications, "letters of intent", checking contracts or writing parts of them, translating techno-speak to presentation-comparible language etc. I already found a few uses in just a few days. Most importantly, it helped me to translate a doctors letter for elder relatives

option + < on german systems/keyboards. keyboard shortcuts are not very accessible to the beginner user though. When my older relatives open youtube videos in fullscreen mode, they do not find their other browser window anymore

this hypothetical best case is an exception to the reality of factory farming and animal "products" included in most dishes ("1% milk powder"). And in even then it would still include animal suffering. For those not too set on their habits, considering the arguments in https://veganspeak.info/ (e.g. #29) might be inspiring.

It is a personal decision in the end, our society allows for mass-producing and killing living beings despite better alternatives. As with other personal choices that are harmful and arbitraty, this is not something I see as worthy of further appreciation, or beneficial for further discussion.

in weeks with more spontaneous requests I use https://calendly.com/ and put a link in my profile to announce daily meeting slots

the "meat" in "meatless meat" describes a texture and taste profile, not an ingredient. It is easier to communicate than, say, "chewy but soft, fibrous proteins which taste is usually determined by umami and maillard reaction flavors".

There is a large community around new recipes for this taste profile, e.g. https://seitansociety.com/ .

compared to the logistics (animal farming and slaughter pipelines), artificial inseminations, medical interventions (antibiotics), storage and food safety concerns around meat, plus the incredible daily amount of animal suffering caused by this consumption, I don't see meat as a "natural" product. all the steps in the "production" process can introduce factors that can degrade the quality and be risky to health (e.g. not cooled at appropriate temperature, antibiotics treatments to animals etc), while with plant proteins, you have far less processing steps between field and table. to vegans and people concerned with reducing global warming, the benefits outweigh the different composition by far.

This would enable a much appreciated Obsidian plugin, it seems a natural fit

In addition to the omission of studies about plant based diets, it glosses over the main concern.

"Veganism is a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of animals, humans and the environment. In dietary terms it denotes the practice of dispensing with all products derived wholly or partly from animals." https://www.vegansociety.com/go-vegan/definition-veganism

You could make a similar argument about slavery, the reason we abolished it has nothing to do with productivity estimations.

I have a similar approach, I found some kanban concepts useful to prevent queues

- board structure to aid sorting before a "commitment point", e.g. "Options/New" - Later(6 weeks) - Soon (in the next 7 days)

- Now (usually just the top or highlighted item in "soon") - Done - Closed

- Closed" to place items that are dismissed

- Work in Progress (WIP) - Limits on all columns - maximum number of items

Throughput

- average capacity: number of cards completed or closed in a typical week

- useful to keep track of: when I complete a card, I add a dot somewhere (usually on a "note card") to count it for the week, and add info when blocked by sth

- this number varies, but is a useful indicator how much I can realistically process in a week - for example, 5 items/cards

WIP (Work in progress) limits

- visualize expectations - what can realistically be achieved in this timeframe

- set per column limits - when more cards are in the column, I have to remove some or transfer them to a wishlist

- wip limits determined by average number of cards closed or done per week (throughput); e.g. "Later (WIP 20)"; "Soon" - WIP 5;

Managing Flow / preventing queues

- planning with smaller steps (could each be done in a day) to enable learning

- avoiding a situation when too many things are started but not completed

- understanding the cost of queues: nothing gets done for a long time, and then all at once (unpredictable patterns); or the value diminishes (cost of delay)

not quite, the most important part of my todo list checking is manually moving items to the current days' list. This action is easily done in tick tick by drag and drop, but I feel like I have to do it manually, to create a memory impression strong enough that I remember the task as something important. The whole todo list 'system' is just an artefact of repeated actions that have a higher chance to create helpful memory paths.
