Unless you lose state between step 2 and 3.

This can be addressed with a two pill commit protocol.

This is a two-phase commit protocol already. Placing the pill on my laptop constitutes logging the transaction, so that it is guaranteed to be completed even though it hasn't taken place yet.

I noticed the problem on myself on several occasions and kind of invented the same solution. For example, sometimes I would take a medicament mechanically while doing something else and just a few minutes later, forget if I took it or not. Solution: say loud to myself "I'm taking a pill". Another: sometimes I'd lend some amount money to a colleague, and a few weeks later I'd have a hard time figuring whether they gav…

I picked up this nasty habit of leaving the house and feeling compelled to check to make sure the oven and stove top are off. After years of doing this and feeling silly each time I started checking the oven before I left the house and told myself outloud, "Yes, the oven and stovetop is off". I was surprised how effective this was. Interesting to read this article today and other's solutions to the same problem.

It's a common issue, especially if one has a touch of OCD. Your solution is good. Another one is to use a checklist. I ritually go through the house as the last thing before leaving, but it would be better to use an actual written checklist.

I confirm those "out of place object" reminders work great!

I prefer to leave/drop everything I need in front of the door. This way, even if I'm in a hurry, the door just won't open without picking up whatever item(s) it is that I need to take with me (paperwork, umbrella, notepad, etc.)

A couple days before going on a trip, I start making a pile of things to take. As I remember things, I add them to the pile. It has reduced the problem of forgetting things.

It does sound very similar to plane checklists where the pilot has to call every item verbally.

Yes, you're right! My father was an Air Force pilot and then flew a private plane into his 60's. for 40 years he religiously followed the checklists, calling out and pointing to the relevant part of the plane for each item on the list: "windows and doors, check; wing flaps set for takeoff; seats latched; seat belts locked; etc." http://www.mooneyland.com/wp-content/uploads/2012/06/Mooney_...

Maybe copy/pasting. Highlight part of the code, copy. Go to gedit (or whatev) and paste. Doing this while "calling it".

This also applies to aviation. While pilots execute the same checklist several times each day, year after year, it is still required to verbally call the items on the list. It feels a bit strange doing it when you're sitting in a cockpit alone, but it does really improve accuracy and ensures you're following the same procedure every time whether there is a co-pilot, instructor or nobody sitting in the other seat. I'v…

If you watch an old aviation movie, they have a verbale procedure to go through before starting the engine. "Switches off", "contact", "clear", etc.

Slightly off topic but this practice of talking-out-loud to get yourself doing stuff is also beneficial to people with executive dysfunction. If your executive function is impaired you generally don't have the "internal monologue" or the voice in your head. This makes seemingly simpler things like taking a shower, driving, or eating, very difficult! I'd often "forget" to eat, simply because I could not get myself to…

This technique is also useful for software development, and is referred to as rubber duck debugging ( https://en.wikipedia.org/wiki/Rubber_duck_debugging ). Verbalizing your problem lends you another point of view to your thinking and often allows you to discover the problem yourself.

Writing detailed commit notes can be useful in the same way. I have backed out of a commit during the write up more times than I would like to admit because I realized that I hadn't covered some edge case or I completely forgot about something (like the effect of the change on a report or other sub-system). Writing things out in a way that someone else can understand forces you to re-think through the task in different ways.

I think that the root of this goes back all the way to Zen-type of thinking. In Zen, it's often taught that mind is elusive/delusive and action matters. "Mindlessness (mu-shin)" is often thought of the best way of carrying tasks, and I see a similar principle in many traditional martial arts/craftsmanship; a new learner should just do certain tasks without thinking/questioning, and eventually their muscle memory will…

It does sound very similar to plane checklists where the pilot has to call every item verbally.

It's been applied to surgery with 90-99% reductions in line infection rates. Head nurse calls the surgeon out on checklist violations.

Collaborative general purpose editors nowadays show one user's text selection to other users, so this is straightforward to implement.

Extending the metaphor, some of the older Mesoamerican religions are imperative, in that they involve a lot of telling people what to do. Contrariwise, hermetic magic is purely functional, in that the practitioner expresses a series of state transformations with no side effects.

Could you elaborate on the idea that hermetic magic is purely functional? How does a practitioner make a state transformation in oneself?

One example might be that spirits are said to be bound by arbitrary functions (bizarre ritual ingredients being a famous example). That they respond to and recognize cues.

Another aspect of spirit lore is that the more central or higher in the hierarchy, the less different "pointers" or cues may be required for evocation, and stronger expression of those fewer cues may result. The lower/more numerous spirits might require more specificity or larger seed.

Transformations at a minimum: by inducing a receptive trance state, then by self-suggestion.
