What does a router flood to the network in link-state routing?
The cost of the links directly attached to it.
Upload a lecture’s slides. AI drafts a card for every key fact, you keep the good ones, then study them right here or take them to Anki.
Got an invite code? Redeem it to get started.
Press the card to turn it over.
Every slide is read closely, and each key fact becomes its own card: one fact, one clear question, written for active recall.
One project per course. Add each lecture’s PDF and every slide is read, figures included.
The AI writes cards from the slides, each linked to the slide it came from. You see the cost before it starts.
Go through new cards one at a time: keep it or bin it. Nothing you bin is gone for good.
Review here with spaced repetition, or export an .apkg for Anki. Or both.
Every card sits beside the slide it came from, so checking one takes a glance. Pick another slide and the list follows.
The AI writes every kind of card Anki has, formulas included.
Pictures, charts and tables are cut out of the page, so a card about one diagram shows that diagram, not the whole slide.
The same fact asked on slide 7 and again on slide 19 is found for you, and so is a card with a gap in it.
Next card, new card, edit, cloze, save: all without reaching for the mouse.

What does a router flood to the network in link-state routing?
The cost of the links directly attached to it.
A link-state router runs Dijkstra's algorithm over its topology database.
Routing
The process of routing in a network.
Which algorithm does a link-state router run over its map of the network?
Dijkstra’s shortest-path algorithm.
It finds the shortest path from one node to all the others, and it is named after the Dutch computer scientist who published it.
Distance-vector converges slowly after a link fails because of count-to-infinity[…].
Think about what neighbours keep telling each other about a route that no longer exists.
What does BGP put in every route advertisement, so that a loop can be seen?
The whole AS path the route has travelled.
BGP is a path-vector protocol. The name gives most of it away.
Each one comes back when you are about to forget it, from minutes to months later.
Study in the browser, on your laptop or your phone. Spaced repetition decides what comes back and when, so your time goes to what you are about to forget.
Each answer schedules the card’s next review, from minutes to months, using the same method as modern Anki.
Study one lecture, one course, or everything that is due today at once.
An AI tutor beside the card gives you a nudge without the answer, or explains it once you’ve seen it.
Export cards together with what you’ve learned, or bring your review history over from Anki.
Gemini, Claude or GPT: use the model you prefer. Before anything is generated, you see what it will cost.
Upload a PDF, draft its cards, keep the good ones and start learning. Your first deck is a few minutes away.
