  • Most of these files are ".ps.gz", i.e. postscript files (.ps) compressed with gzip (.gz).
  • Since Mon 15/7/02, I have tried to provide PDF alternatives to all postscript files.
  • Since Sun 20/10/02, DJVU alternatives are also provided.
  • If you don't have gunzip on your machine, you can find gunzip executables for various systems here; the msdos executable is also here. Some users report that gsview32 is useful for viewing the ps.gz files.
    Further links about gzip and gunzip: gzip.org, gzip.html.
    Some users of windows machines find that if they download a ps.gz file by http then it does not unzip and display, but if they download it by ftp, it works fine. To convert an http URL to an ftp URL, please use the following pair as an example:

    ftp://www.inference.org.uk/pub/www/mng10/GP/gpros.ps.gz

  • On July 2nd 2009 I gave a talk for CityForum describing a possible road-map for UK energy to 2050. There is a paper ("Plan C", pdf) and a small set of slides (html). This road-map includes timescales and build-rates.

For enthusiasts: One hundred pages of further notes on topics cut from the book while finishing it - including carbon, climate change, and strategies used for misleading people.

Notes:

  • Version 6.0 was released Thu 26/6/03; the book is finished. You are welcome to view the book on-screen. Version 6.0 was used for the first printing, published by C.U.P. September 2003.
  • Version 6.6 was released Mon 22/12/03; it will be used for the second printing, to be released January 2004. In this second printing, a small number of typographical errors were corrected, and the design of the book was altered slightly. Page-numbering generally remains unchanged, except in chapters 1, 6, and 28, where a few paragraphs, figures, and equations have moved around. All equation, section, and exercise numbers are unchanged.
  • Version 7.0 is the third printing (November 2004). Its only differences from the 2nd printing are a number of corrections, and the renaming of the chapter `Correlated Random Variables' to `Dependent Random Variables'.

Copyright issues: The book is copyright (c) Cambridge University Press. It has been available in bookstores since September 2003. The cover price in 2003 was 30 pounds (UK) and $50 (USA); in 2006, 35 pounds and $60 (USA).

Now the book is published, these files will remain viewable on this website. The same copyright rules will apply to the online copy of the book as apply to normal books. [e.g., copying the whole book onto paper is not permitted.]

Runlength limiting codes, & codes for correcting insertions and deletions

`Reliable communication over channels with insertions, deletions, and substitutions.' Paper appeared in IEEE-IT Feb 2001. See also Matthew Davey's web pages
ERRATUM: (19th March 2001) In the published version of the above IEEE-IT paper, figure 15 contained a minor error, now corrected on the file on this website. Both the dotted `Zigangirov' curves were a tiny bit higher than they ought to be. You can see the difference between the old curves and the corrected curves in this figure and you can also obtain the corrected curves or the entire corrected page.
The error has no influence on the substance of the paper.
This error arose because our definition of the deletion rate (pd) differs by a factor (1-pi) from that of Zigangirov, where pi is the insertion rate.

    Dasher - a Data Entry Interface Using Continuous Gestures and Language Models
    by David J Ward, Alan F Blackwell and David J C MacKay

    Existing devices for communicating information to computers are bulky, slow to use, or unreliable. Dasher is a new interface incorporating language modelling and driven by continuous two-dimensional gestures, e.g. a mouse, touchscreen, or eye-tracker. Tests have shown that this device can be used to enter text at around 25 words per minute, compared with typical ten-finger keyboard typing of 40 - 60 words per minute.

    Although the interface is slower than a conventional keyboard, it is small and simple, and could be used on personal data assistants and by handicapped computer users.

    Problems using this archive? Some questions and answers.

    Note : If you prefer to get documents by ftp rather than by clicking in a web browser, then you can get to most of these files by anonymous ftp to wol.ra.phy.cam.ac.uk, cd pub/www/mackay.

    Conversely, if you want to get a document by http rather than by ftp, change the address from ftp://www.inference.org.uk/pub/www/mackay/blah to http://www.inference.org.uk/mackay/blah.

    when I logged into your web address as sent, I got a bunch of nondescript characters which at least my Nestscape 1.12 was not deciphering.
    OK - that means that your Netscape doesn't know about uncompressing files ending in .ps.gz and displaying them with ghostview. The thing to do in that situation is to select "Save As file" from the "File" menu, saving to name.ps.gz, then uncompress (gunzip) it by hand and then view the postscript in your favourite manner.
