Sometimes you want to exclude a directory and/or files from a search. This alias:

cfind=’find . \( -type d -name .svn -prune -o -path ./stock-data/tests/data -prune \) -o \( -type f \! -name “*.csv” -print0 \) | xargs -0 grep’

…means:

“Recursively loop through all of the files and directories in the current directory and below. If it’s a directory named .svn or it’s in the stock-data path, or it ends in .csv ignore it. Otherwise, search for your keyword in the file.”

Type the following in the python interpreter:

help()
modules
[name of module]

You should see a list of the methods in the module with their descriptions.

Suppose you want pass in a complex query to a command line sql interpreter from within a shell script. You can do so with a command like this:

sql92 <<EOF 
    connect to db1 as LASTTRADES user eouser; 
    set format row; 
    select  p.fundkey as fundkey, 
        max(t.closed) as last_trade 
    from    mposition p, mtrade t 
    where   p.primarykey=t.positionkey 
     and    t.createdbycorporateaction=0 
    group by fundkey; 
EOF 

But for the life of me, I can’t recall it, or find it on the web. Anyone know this off hand?

If you want to use a newly installed rubygems, and you don’t want to require ‘rubygems’ for every program that uses a gem, you need to set the RUBYOPT environment variable. For example, if you’re using tcsh, you should put the following in your .tcshrc file:

setenv RUBYOPT rubygems

This will cause the rubygems module to be loaded every time your run a ruby script.

If you call an external python script from within ruby, make sure you have any pdb.set_trace() lines commented out. When the ruby script tries to run the program, it will just hang at the point you set the trace, without giving you any output. For example, if test.py script has a pdb.set_trace() set, and you run the following command from within irb, the line will never finish executing. You’ll have to interrupt it with a CTRL-C command.

dfi_result = `/Users/build/crasch/PythonScripts/test.py -positions -total -infile /MData/Data/vyslf.csv -MStderrLoggingThreshold 3`

I’m using Thunderbird (version 2.0.0.0) on a 2.16 GHz Intel Core 2 Duo (1 GB Ram) running Mac OS X 10.4.9. When I connect to my account at fastmail.fm via IMAP, it frequently takes several minutes for each folder to open, and when I send mail, it often takes several minutes to copy the sent mail to the Sent folder (and sometimes it fails altogether.) Has anyone else experienced this problem? Any suggestions for what I might do to debug it?

[Edit: This has been going on for a couple of weeks, and happened when I was running the previous release of Thunderbird. If I stop and restart Thunderbird, it goes away for a while. ]

Thanks!
