2.1 Gnosis Dashboard

The first thing new users should familiarize themselves with is ‘gnosis-dashboard’, which you can access via M-x gnosis-dashboard.

You can start a review session from the dashboard by pressing r or with M-x gnosis-review.

NOTE: Gnosis supports reviewing specifics topics for notes of ‘org-gnosis’ with M-x gnosis-review-topic

You can add new themata from the dashboard a or with M-x gnosis-add-thema

2.2 Linking Themata to Note Topics

We can create a demo note topic for Vancomycin, an antibiotic, with M-x org-gnosis-find RET Vancomycin. For this demo, just save the buffer contents by pressing C-x C-s.

Back to the dashboard M-x gnosis-dashboard, we can view all our themata by pressing n or we can press s to search our themata. For this demo, we are looking for a thema from the demo deck we imported, that contains a questions about ‘Vancomycin’.

To link that thema to the note topic we created before, press e to edit the thema. In the ‘Keimenon’ section delete “Vancomycin” and press M-x org-gnosis-insert RET Vancomycin.

After saving the thema with M-x C-c C-c, you can review all themata linked to that topic by M-x gnosis-review-topic.

3.1 Cloze

A cloze note type is a format where you create sentences or paragraphs with “missing” words. A fill-in-the-blanks question.

You can create a cloze note type using ‘M-x gnosis-add-thema’ and selecting Cloze.

Example format:

• Default cloze format
• Using anki-like syntax

* Thema                      :pharmacology:antimicrobials:penicillin:

:GNOSIS_ID: NEW

What is the treatment for Actinomyces infection?

Penicillin

** Hypothesis
- drug type

** Answer
- Penicillin

** Parathema
Sulfonamides → Nocardia
Actinomyces → [[id:680ca944-8ee9-4513-92d6-25696ee01f48][Penicillin]]
(treatment is a SNAP)

** Keimenon
A 60-year-old man comes to the physician with chills, nausea, and
diffuse muscle aches for 3 days. His niece had similar symptoms 2
weeks ago and H3N2 influenza strain was isolated from her respiratory
secretions. He received his influenza vaccination 2 months ago. His
temperature is 38.5°C. A rapid influenza test is
positive. Which of the following mechanisms best explains this
patient's infection despite vaccination?

** Hypothesis
- Random point mutations within viral genome
- Complementing with functional viral proteins
- Exchange of viral genes between chromosomes
- Reassortment of viral RNA segments
- Acquisition of viral surface proteins

** Answer
- Random point mutations within viral genome

** Parathema
Random point mutations within the viral genome are responsible for
antigenic drift, which creates a new virus strain.

5.1 Typos | String Comparison

You can adjust ‘gnosis-string-difference’, this is a threshold value for string comparison that determines the maximum acceptable Levenshtein distance between two strings, which identifies their similarity

Let’s illustrate with an example:

(setf gnosis-string-difference 1)

In this scenario, we set ‘gnosis-string-difference’ to 1. This implies that two strings will be recognized as similar if they exhibit a difference of at most one character edit.

To demonstrate, ’example’ and ’examples’ will be recognized as similar, considering that the latter involves just one additional character."

6.1 Anagnosis Event

Anagnosis, which means comprehension & recognition of knowledge, is triggered when the consecutive successful or failed recalls are equal or greater to anagnosis value.

When anagnosis is triggered by consecutive successful recalls, epignosis value is added to gnosis-plus. Epignosis means accuracy of knowledge.

When anagnosis is triggered by consecutive failed recalls, agnoia value is added to gnosis-minus. Agnoia means lack of knowledge

You can set specific values for each deck and tag of the variables mentioned above by adjusting ‘gnosis-custom-values’.

6.2 Lethe event

The Lethe event triggers after a certain number of consecutive failures to recall an answer correctly.

When this threshold is reached, the next interval is reset to 0.

For example, with lethe value of 2, upon having 2 consecutive failed recalls the next review will be set for the current day.

6.3 Proto

The default initial interval is defined at ‘gnosis-algorithm-proto’, you can define a custom initial interval for each deck as well.

‘gnosis-algorithm-interval’ is a list of numbers, representing the first initial intervals for successful reviews. There is no limit on the length of the list.

Example:

(setq gnosis-algorithm-interval '(0 1 2 30))

Upon each successful note review, the algorithm will increment to the next interval value: 0 days (0), 1 day later (1), 2 days later (2), and 30 days later.

Upon failing to review a note without completing it’s proto successful reviews, it’s next review date will be on the same date.

9.1 emacs-no-littering

If you are a user of emacs-no-littering, you can theme Gnosis to fit its standards by adding the following snippet to your configuration:

(setq gnosis-dir (no-littering-expand-var-file-name "gnosis/"))

This sets ‘gnosis-dir’ to ‘~/.emacs.d/var/gnosis’, in line with the folders of other packages.

10.1 How to create a patch

Example:

$ git clone https://git.thanosapollo.com/gnosis.git && cd gnosis
$ emacs something
$ git add something
$ git commit -m "Fix something"
$ git format-patch HEAD^1
0001-Fix-something.patch

You can sent the patch to “Thanos Apollo”, the email of which you can find on the git log.
