I have a small app on heroku. Whenever I want to see the logs I go to the command line and do
heroku logs
That only shows me about 100 lines. Is there not a way to see complete logs for our application on heroku?

I'm using logback in my current project.
It offers six levels of logging: TRACE DEBUG INFO WARN ERROR OFF
I'm looking for a rule of thumb to determine the log level for common activities.
For instance, if a thread is locked, should the log message be set to the debug level or the info level.
Or if a socket is being used, should its specific id be logged at the debug level or the trace level.
I will appreciate answers with more examples for each logging level.

How can I show a git log output with (at least) this information:
* author
* commit date
* change
I want it compressed to one line per log entry. What's the shortest possible format for that?
(tried --format=oneline but that does not show the date)

When logging in C#, how can I learn the name of the method that called the current method? I know all about System.Reflection.MethodBase.GetCurrentMethod(), but I want to go one step beneath this in the stack trace. I've considered parsing the stack trace, but I am hoping to find a cleaner more explicit way, something like Assembly.GetCallingAssembly() but for methods.

Can anyone tell me how to enable logging of all SQL executed by PostgreSQL 8.3? Thanks!
Edited (more info)
I changed these lines :
log_directory = 'pg_log'
log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log'
log_statement = 'all'
And restart PostgreSQL service... but no log was created...
I´m using Windows Server 2003.
Any ideas?

I would like to grep for a string, but also show the preceding five lines and the following five lines as well as the matched line. I'm scanning for errors in a logfile, and want to see the context.
Is it possible?

SVN's log has a "-v" mode that outputs filenames of files changed in each commit, like so:
jes5199$ svn log -v
------------------------------------------------------------------------
r1 | jes5199 | 2007-01-03 14:39:41 -0800 (Wed, 03 Jan 2007) | 1 line
Changed paths:
A /AUTHORS
A /COPYING
A /ChangeLog
A /EVOLUTION
A /INSTALL
A /MacOSX
Is there a quick way to get a list of changed files in each commit in git?

Python 2.6 introduced the str.format() method with a slightly different syntax from the existing % operator. Which is better and for what situations?
The following uses each method and has the same outcome, so what is the difference?
#!/usr/bin/python
sub1 = "python string!"
sub2 = "an arg"
a = "i am a %s" % sub1
b = "i am a {0}".format(sub1)
c = "with %(kwarg)s!" % {'kwarg':sub2}
d = "with {kwarg}!".format(kwarg=sub2)
print a # "i am a python string!"
print b # "i am a python string!"
print c # "with an arg!"
print d # "with an arg!"
Furthermore when does string formatting occur in Python? For example, if my logging level is set to HIGH will I still take a hit for performing the following % operation? And if so, is there a way to avoid this?
log.debug("some debug info: %s" % some_info)

By default, the Requests library writes log messages to the console, along the lines of Starting new HTTP connection (1): example.com etc. I'm usually not interested in these messages, how do I disable them?
