gloryhole, a drawer in whichthings are heaped together without any attempt at order or tidiness;

Writing permanent notes was time consuming as f***. On one side writing them helped me grasp the concepts they described on a deep level. One the other side I think this would have been possible without putting an emphasis on referencing, atomicity, deep linking, etc.

One of the first things that was discovered about building complicated technical hypertext is that you don’t know what the structure will be in advance. And as you’re adding information, you know you want to keep the information, but you frequently don’t know what the information you’re adding is. You can’t describe its type or its nature or its importance in advance. You just suspect that it’s going to be pertinent somehow. Or you see a terrific quotation that you know will be great to use, but you don’t know when that quotation will fit or even if it’ll fit in this book, or if you’ll have to save it for something else. Finding ways to say, “I think these two things are related somehow, but I don’t want to commit myself yet as to exactly how,” turns out to be quite an interesting design problem. Hypertext people started out, in fact, by inventing the outliner very early — 1968. And outliners are terrific if you already know the structure of your information space. But hierarchies are not good if you’re just guessing about how things fit together because you tend to build great elaborate structures that turn out to be wrong, and you have to unbuild them, and then you’ve got a terrible pile on your desk.

If you can’t talk yourself into using your energy to write or type something out, it’s probably not worth capturing.

Most men's notes are useless stuff to others, useless even to them-selves with the passage of time, and useless especially because ofchaotic arrangement.

As Francis Bacon warned long ago, ‘One man’s notes will little profit another.’

The awful warning is Lord Acton, whose enormous learning never resulted in the great work the world expected of him. An unforgettable description of Acton’s Shropshire study after his death in 1902 was given by Sir Charles Oman. There were shelves and shelves of books, many of them with pencilled notes in the margin. ‘There were pigeonholed desks and cabinets with literally thousands of compartments into each of which were sorted little white slips with references to some particular topic, so drawn up (so far as I could see) that no one but the compiler could easily make out the drift.’ And there were piles of unopened parcels of books, which kept arriving, even after his death. ‘For years apparently he had been endeavouring to keep up with everything that had been written, and to work their results into his vast thesis.’ ‘I never saw a sight,’ Oman writes, ‘that more impressed on me the vanity of human life and learning.’

Newspaper clippings were usually placed in boxes or file storages dependingon their scientific or otherwise valuable content. This procedure is inadequate as it means thatone forgets about the clipping when it might have been useful, or, if one does not forget aboutthe clipping, it is nowhere to be found in the ever growing pile of collection folders (or canonly be found after hours of searching for it).

Don’t let it pile up. A lot of people mark down passages or fold pages of stuff they like. Then they put of doing anything with it. I’ll tell you, nothing will make your procrastinate like seeing a giant pile of books you have to go through and take notes on it. You can avoid this by not letting it pile up. Don’t go months or weeks without going through the ritual. You have to stay on top of it.

AS PAPER became ever more abundant from the fourteenth century onward, note-taking proliferated, expanding from erasable wax tablets (the method used by Cicero and medieval wool merchants) and erasable donkey skin to permanent slips of paper and notebooks. An early-modern term for notes was “scraps.” Piles of them were called scrap heaps, and tragically for historians, most notes ended up there. Yet notes made in the margins of great printed books survived, and they are like rare seashells in the sands of the libraries.

Thus the lessonto be learned is that when designing algorithms that operate on trees, it is important to be most efficienton the bottommost levels of the tree (as BuildHeap is) since that is where most of the weight of the treeresides.

Merge is a recursive operation.

In order to maintain this property, each node has a rank, which indidates the length of the path between the node and the right most leaf. For example,
