Dear me it was tough finding the right way to get my latest paper ready to submit to the ACM.

What they needed was basically are PS and PDF files created from TeX that had all the fonts embedded in them.

For PDFs, there were a lot of webpages that talked about adding the following line to: /usr/share/texmf/web2c/updmap.cfg


pdftexDownloadBase14 true


This did not work for me.

What did work for me was to use ghostscript to embed all the fonts in the PDF:

1) Generate PDF with pdflatex:


pdflatex in.tex


2) Embed all fonts with ghostscript


gs -sDEVICE=pdfwrite -q -dBATCH -dNOPAUSE -dSAFER -dPDFX -dPDFSETTINGS=/prepress -dAutoFilterColorImages=false -dColorImageFilter=/FlateEncode -dAutoFilterGrayImages=false -dGrayImageFilter=/FlateEncode -sOutputFile=out.pdf -c "<</NeverEmbed []>> setdistillerparams" -f in.pdf -c quit


3) Make sure all the fonts are embedded


pdffonts out.pdf



For generating a Postscript file:

1. Add the following lines to /usr/share/texmf/web2c/updmap.cfg


sudo vi /usr/share/texmf/web2c/updmap.cfg

dvipsDownloadBase35 true
dvipsDownloadBase14 true


2. Update font map files for TeX output drivers.


sudo updmap


3. Create the .dvi file


latex file.tex


4. Create the .ps file


dvips file.dvi -o file.ps



You might not have to do steps 1 and 2, but I had a figure with an embedded Helvetica font in it, and the first two lines were necessary to properly embed that font as well.

micro/macro




From : ocn506

Micro and Macro Readings Main ideas (excerpted or paraphrased) and page number:
detail can add clarification
39 - graphical indexing can be useful instead of tables to show how science changes over time
43 - consider innovative ways to order information
50 - Tufte is really wordy sometimes :)
51 - high density of information is good, clutter is a design flaw

38 - micro/macro designs report immense detail, organized complexity through multiple and hierarchical layers of contextual reading
46 - micro/macro designs have multifunctioning graphical elements
49 - micro/macro designs portray large quantities of data at high densities
50 - micro/macro designs enforce both local and global comparisons and at the same time, avoid the disruption of context switching
51 - clutter and confusion are failures of design, not attributes of information; seek instead a rich texture of data, a comparative context, an understanding of complexity revealed with an economy of means.

spring




Spring-Loaded Modes - A spring-loaded mode is one that persists only as long as the user explicitly does something to keep it active. The most typical example is a state that exists as long as the user holds down a mouse button. As soon as the user releases the button, the system exits the temporary state.

This is a nice solution to a user-interface problem I've been trying to solve. The spring loaded mode will be triggered by the user holding down the control key. Nice.

numeric




I had a string field in a MySQL database connected to Rails that contained a long series of mostly numbers:


001
002
010
023
100_1
200


And I wanted to order them numerically. I found the answer at How to do natural alpha-numeric sort in MySQL and the code I use is:


@recordings = Recording.paginate :page => params[:page], :per_page => 10, :order => 'tape + 0', :conditions => { :year => params[:id] }


That little:


:order => 'tape + 0'


Is what was needed. Neat!

Sadly, mozex isn't working anymore for Firefox 3.0. I was looking at hacking it to make it work, and make it work better with Emacs, but then I found:

Unfortunately, this didn't seem to work with my emacsclient setup, until I found:

So, I just editted my "firefox-emacsclient" script to look like this:

Goregous plotting out of Python with matplotlib


fft



spectro




Matlab spectrogram code


function X = spectrogram(x,nfft,fs,window,noverlap,doplot,dbdown);

%SPECTROGRAM Calculate spectrogram from signal.
% B = SPECTROGRAM(A,NFFT,Fs,WINDOW,NOVERLAP) calculates the
% spectrogram for the signal in vector A.
%
% NFFT is the FFT size used for each frame of A. It should be a
% power of 2 for fastest computation of the spectrogram.
%
% Fs is the sampling frequency. Since all processing parameters are
% in units of samples, Fs does not effect the spectrogram itself,
% but it is used for axis scaling in the plot produced when
% SPECTROGRAM is called with no output argument (see below).
%
% WINDOW is the length M window function applied, IN ZERO-PHASE
% FORM, to each frame of A. M cannot exceed NFFT. For M<NFFT,
% NFFT-M zeros are inserted in the FFT buffer (for interpolated
% zero-phase processing). The window should be supplied in CAUSAL
% FORM.
%
% NOVERLAP is the number of samples the sections of A overlap, if
% nonnegative. If negative, -NOVERLAP is the "hop size", \ie, the
% number of samples to advance successive windows. (The overlap is
% the window length minus the hop size.) The hop size is called
% NHOP below. NOVERLAP must be less than M.
%
% Thus, SPECTROGRAM splits the signal into overlapping segments of
% length M, windows each segment with the length M WINDOW vector, in
% zero-phase form, and forms the columns of B with their
% zero-padded, length NFFT discrete Fourier transforms.
%
% With no output argument B, SPECTROGRAM plots the dB magnitude of
% the spectrogram in the current figure, using
% IMAGESC(T,F,20*log10(ABS(B))), AXIS XY, COLORMAP(JET) so the low
% frequency content of the first portion of the signal is displayed
% in the lower left corner of the axes.
%
% Each column of B contains an estimate of the short-term,
% time-localized frequency content of the signal A. Time increases
% linearly across the columns of B, from left to right. Frequency
% increases linearly down the rows, starting at 0.
%
% If A is a length NX complex signal, B is returned as a complex
% matrix with NFFT rows and
% k = floor((NX-NOVERLAP)/(length(WINDOW)-NOVERLAP))
% = floor((NX-NOVERLAP)/NHOP)
% columns. When A is real, only the NFFT/2+1 rows are needed when
% NFFT even, and the first (NFFT+1)/2 rows are sufficient for
% inversion when NFFT is odd.
%
% If DOPLOT is nonzero, the spectrogram will be plotted in any case.
% DBDOWN (default=100) sets the clip level below the maximum in dB.
%
% See also: Matlab's SPECGRAM function.

I'm going to use Protocol Buffers for doing my data serialization in my new projects. protobuf is from Google and is a way of encoding structured data in an efficient yet extensible format. Google uses Protocol Buffers for almost all of its internal RPC protocols and file formats. There is an overview of Protocol Buffers that is good reading.

You know, for years I promoted the use of XML for data interchange, but now I think that XML is too heavyweight for doing most kinds of data interchange, and should be instead used for data archiving. That's too bad, XML looked really sweet there, but really, performance does matter.

paper




An excerpt from my latest paper:

"Instead of viewing these pitches to be deviations
of pre-existing ``normalized'' scales our method defines a more
differentiated scale from the outset. With our approach the scale
tones do not require ``normalization'' and thereby exist in an
autonomous microtonal environment defined solely on statistical
occurrence of pitch within a temporal unfolding of the given melodic
context."

translation




The indeterminacy of translation:

"Consider Quine's example of the word 'gavagai' uttered by a native upon seeing a rabbit[1]. The linguist could do what seems natural and translate this as 'Lo, a rabbit.' But other translations would be compatible with all the evidence he has: 'Lo, food'; 'Let's go hunting'; 'There will be a storm tonight' (these natives may be superstitious); 'Lo, a momentary rabbit-stage'; 'Lo, an undetached rabbit-part.' Some of these might become less likely ? that is, become more unwieldy hypotheses ? in the light of subsequent observation. Others can only be ruled out by querying the natives: An affirmative answer to 'Is this the same gavagai as that earlier one?' will rule out 'momentary rabbit stage,' and so forth. But these questions can only be asked once the linguist has mastered much of the natives' grammar and abstract vocabulary; that in turn can only be done on the basis of hypotheses derived from simpler, observation-connected bits of language; and those sentences, on their own, admit of multiple interpretations, as we have seen."

"Q: when running Weka, we get "Train and test set are not compatible" error.
A: 1. Make sure that the train and test sets have EXACTLY the same attributes (fields),
including last entry:
@attribute Class {MED,MGL,RHB,EPD,JPA}
2. If the attribute descriptions appear to be identical but you still get the same error, you may have an invisible control character in one of the files. Remove the attribute descriptions from the test file and replace them with the attribute descriptions from the train file. That may help.
