Cache 901 is an advanced paperless geocaching program, allowing easy maintenance of a large number of caches locally. It is especially designed to work well on netbooks, allowing them to be taken on the trail and provide any assistance that can be gotten from the data you store. This can include advanced searching capabilities, logs, photos, and personal notes for any cache. License: GNU General Public License v2 Changes:
This version maps out cache locations. It provides advanced searching capabilities. It has logging of caches, along with personal notes and photos for each cache. It supports integration with GPSr's. The new Cache Day feature is not found elsewhere.
Hi All,
could any one point out any open source test-suites for "File cache" testing and as well as performance test suites for the same. Currently my system is up with Linux/ext4.

Hi all
I saw in Microsoft web site www.SysInternals.com a tool called CoreInfo from able to print out on screen the size of the Data and Instruction caches of your processor, the Locigal to Physical Processor mapping, the number of the CPU sockets. etc..
Do you know if in Linux is available a... (2 Replies)

Cache::Historical - Cache historical values
SYNOPSIS
use Cache::Historical;
my $cache = Cache::Historical->new();
# Set a key's value on a specific date
$cache->set( $dt, $key, $value );
# Get a key's value on a specific date
my $value = $cache->get( $dt, $key );
# Same as 'get', but if we don't have a value at $dt, but we
# do have values for dates < $dt, return the previous
# historic value.
$cache->get_interpolated( $dt, $key );
DESCRIPTION
Cache::Historical caches historical values by key and date. If you have something like historical stock quotes, for example
2008-01-02 msft 35.22
2008-01-03 msft 35.37
2008-01-04 msft 34.38
2008-01-07 msft 34.61
then you can store them in Cache::Historical like
my $cache = Cache::Historical->new();
my $fmt = DateTime::Format::Strptime->new(
pattern => "%Y-%m-%d");
$cache->set( $fmt->parse_datetime("2008-01-02"), "msft", 35.22 );
$cache->set( $fmt->parse_datetime("2008-01-03"), "msft", 35.37 );
$cache->set( $fmt->parse_datetime("2008-01-04"), "msft", 34.38 );
$cache->set( $fmt->parse_datetime("2008-01-07"), "msft", 34.61 );
and retrieve them later by date:
my $dt = $fmt->parse_datetime("2008-01-03");
# Returns 35.37
my $value = $cache->get( $dt, "msft" );
Even if there's no value available for a given date, but there are historical values that predate the requested date, "get_interpolated()"
will return the next best historical value:
my $dt = $fmt->parse_datetime("2008-01-06");
# Returns undef, no value available for 2008-01-06
my $value = $cache->get( $dt, "msft" );
# Returns 34.48, the value for 2008-01-04, instead.
$value = $cache->get_interpolated( $dt, "msft" );
Methods
new()
Creates the object. Takes the SQLite file to put the date into as an additional parameter:
my $cache = Cache::Historical->new(
sqlite_file => "/tmp/mydata.dat",
);
The SQLite file defaults to
$HOME/.cache-historical/cache-historical.dat
so if you have multiple caches, you need to use different SQLite files.
time_range()
# List the time range for which we have values for $key
my($from, $to) = $cache->time_range( $key );
keys()
# List all keys
my @keys = $cache->keys();
values()
# List all the values we have for $key, sorted by date
# ([$dt, $value], [$dt, $value], ...)
my @results = $cache->values( $key );
clear()
# Remove all values for a specific key
$cache->clear( $key );
# Clear the entire cache
$cache->clear();
last_update()
# Return a DateTime object of the last update of a given key
my $when = $cache->last_update( $key );
since_last_update()
# Return a DateTime::Duration object since the time of the last
# update of a given key.
my $since = $cache->since_last_update( $key );
