Flock is the ultimate web browser based on the popular Firefox.
Welcome to the Flock Developer Preview, aka the Flock 0.5pre developer snapshot. If you have made it this far, chances are that you are aware of the risks associated with software that is nestled somewhere between the alpha and beta states.
While we are very excited about what we are doing, we want to make sure that you have been fully forewarned that this browser will crash from time to time and that any settings you save in this browser may quite possibly be erased, lost, or overwritten! Please have a backup of your blog posts and your shared bookmarks! Given that, we strongly recommend that you proceed with caution. Still here? Great!
So before you get started, please read through these release notes. This will give you some of the relevant information you will need to get up and running. Also, if you have general questions about Flock, who we are, what we do, and how we get away with it, please check out flock.com. Thanks for your interest in Flock; we hope you enjoy your stay.
Flock Developer Preview includes a number of features and services that make it fun and easy to talk back to the web and organize, share and retrieve interesting web pages.
Main features:
- The Blog Manager
- The Flickr Topbar
- RSS integration
- Favorites with del.icio.us integration
- The Shelf
- History Search
Flock Developer Preview is now available.
Our code couldnt wait any longer to be free!
But! This preview aint for the faint of heart! If youre the bleeding-edge type and dont mind a few scrapes and busted knees from time to time, feel free to give it a whirl.
Weve got interesting ideas in this thing. We want to know what weve done right how we could improve. And weve got a lot of work ahead of us!
- Flock still doesnt import your Firefox or IE favorites
- Flock does support Flash, but other plug-ins have NOT been tested
- While we have ten or so of the most popular Firefox extensions working, we need to come up a way to make most Firefox extensions working in Flock and/or cajole extension authors to make their extensions work with Flock
- A weird timestamp/debug window shows up when you publish a blog post. Were on the case. But your post will get published just fine
- Firefox themes do not work with Flock
- Choice! We like it as much as you do, but we must crawl before we can walk. While we support a number of blogging platforms, we dont yet offer a choice of social bookmark services or photo sharing services
- Blogging platforms: WordPress and Blogger work pretty well. There are some problems still with Movable Type. We havent tested any other blogging platforms
- Bad things happen if you say "Yes, share my bookmarks" and then dont enter del.icio.us account info
Finally, there is a list of several hundred bug reports and ideas for feature improvements, including some bugs that will make your browser crash. So consider this software experimental, and be prepared for crashes and occasional data losses. We do not recommend that you use Flock 0.5 as your main web browser.

File::Flock 104.111901
File::Flock is a Perl module for file locking with flock. more>>
File::Flock is a Perl module for file locking with flock.
SYNOPSIS
use File::Flock;
lock($filename);
lock($filename, shared);
lock($filename, undef, nonblocking);
lock($filename, shared, nonblocking);
unlock($filename);
my $lock = new File::Flock /somefile;
lock_rename($oldfilename, $newfilename)
Lock files using the flock() call. If the file to be locked does not exist, then the file is created. If the file was created then it will be removed when it is unlocked assuming its still an empty file.
Locks can be created by newing a File::Flock object. Such locks are automatically removed when the object goes out of scope. The unlock() method may also be used.
lock_rename() is used to tell File::Flock when a file has been renamed (and thus the internal locking data that is stored based on the filename should be moved to a new name). unlock() the new name rather than the original name.

Flock of Birds Library 1.0.2
Flock of Birds Library (libfob) provides an interface to the Flock of Birds hardware. more>>
Flock of Birds Library (libfob) provides an interface to the Flock of Birds hardware. Tedious and error prone tasks such as configuring the flocks data mode, sending commands to the flock, and decoding the data received from the flock are all hidden behind libfobs interface.
Programming the flock hardware can be hard. The programmer has to worry about in which format the flock returns data (pos/quat, quat, mat, pos, angles, pos/angles, etc.) Configuring the flock is error prone and hard to get correct. For older version of the Flock of Birds hardware, simply starting the flock can be a chore.
In contrast, libfob has been designed to be easy to use. The programmer simply tells the library the following:
- Serial port the flock is attached to (ex: "/dev/ttyS0").
- Hemisphere the flock should operate in (ex: "DOWN").
- Maximum speed the flock can operate ("FAST" for newer flock hardware "SLOW" for older hardware).
The programmer can then configure the flock on a per bird basis. Any combination of the following information can be retrieved from a bird in the flock:
- Position
- Orientation
- Buttons
At any time, the programmer can retrieve the above information in any of the following formats:
- Quaternion (represents orientation)
- Vector (represent position)
- 4x4 Matrix (represents position/orientation)
The programmer pays no penalty for retrieving data in one format over another. Internally libfob configures the flocks hardware to send data as fast as possible. libfob maintains multiple representations of the data for fast retrieval by the programmer.
libfob also provides facilities to correct orientation information for incorrectly installed bird sensors.

File::lockf 0.20
File::lockf is a Perl module interface to the lockf system call. more>>
File::lockf is a Perl module interface to the lockf system call.
SYNOPSIS
use File::lockf;
File-Lockf is an interface to the lockf system call. Perl supports the flock system call natively, but that does not acquire network locks. Perl also supports the fcntl system call, but that is somewhat ugly to use. There are other locking modules available for Perl, but none of them provided what I wanted -- a simple, clean interface to the lockf system call, without any bells or whistles getting in the way.
File-Lockf contains four functions which map directly to the four modes of lockf, and an OO wrapper class that encapulates the basic locking functionality along with an additional utility method that iteratively attempts to acquire a lock.
Lock functions
The following functions return 0 (zero) on success, and the system error number from errno on failure. They each take an open file handle as the first argument, and optionally a size parameter. Please see your system lockf man page for more details about lockf functionality on your system.
$status = File::lockf::lock(FH, size = 0)
This function maps to the F_LOCK mode of lockf.
$status = File::lockf::tlock(FH, size = 0)
This function maps to the F_TLOCK mode of lockf.
$status = File::lockf::ulock(FH, size = 0)
This function maps to the F_ULOCK mode of lockf.
$status = File::lockf::test(FH, size = 0)
This function maps to the F_TEST mode of lockf.
OO wrapper
File-Lockf also provides a simple OO wrapper class around the locking functionality, which allows you to create a lock object for a file handle and then perform lock operations with it. All of the methods return 0 (zero) on success, and the system error number from errno on failure.
$lock = new File::lockf(*FH)
This function returns a new lock object bound to the given file handle. Note that you need to pass a reference to the file handle to the constructor, not the file handle itself.
$status = $lock->lock(size = 0)
This method calls File::lockf::lock on the bound file handle.
$status = $lock->tlock(size = 0)
This method calls File::lockf::tlock on the bound file handle.
$status = $lock->ulock(size = 0)
This method calls File::lockf::ulock on the bound file handle.
$status = $lock->test(size = 0)
This method calls File::lockf::test on the bound file handle.
$status = $lock->slock(count = 5, delay = 2, size = 0)
This method will attempt to lock the bound file handle < count > times, sleeping < delay > seconds after each try. It will return 0 if the lock succeeded, or the system error number from errno if all attempts fail.

libfilo 0.11
libfilo is a small portable library to do userspace file locking, like fcntl(), lockf() or flock(), but within threads. more>>
libfilo is a small portable library to do userspace file locking, like fcntl(), lockf() or flock(), but within threads.
If you want multiple threads to access a file simultaneously, you will probably need some kind of locking to avoid them stepping on each other and corrupting everything. Currently, there is no standard way of doing this:
- fcntl() ignores threads, and only works between processes.
- flock() is not really standard and doesnt work well over NFS.
- lockf(), while it is documented in POSIX, its often implemented using fcntl() so its also useless.
So this library allows you to do read/write file locking with byte granularity and fcntl-like semantics, within threads. Its written in C, in about 600 lines of code, and has no dependencies on external libraries.
Its based on the traditional POSIX API and follows the Single UNIX Specification, so it should be portable to all major UNIX variants without problems; however its developed under Linux, so please let me know if you try it somewhere else.

LockFile::Simple 0.2.5
LockFile::Simple is a simple file locking scheme. more>>
LockFile::Simple is a simple file locking scheme.
SYNOPSIS
use LockFile::Simple qw(lock trylock unlock);
# Simple locking using default settings
lock("/some/file") || die "cant lock /some/filen";
warn "already lockedn" unless trylock("/some/file");
unlock("/some/file");
# Build customized locking manager object
$lockmgr = LockFile::Simple->make(-format => %f.lck,
-max => 20, -delay => 1, -nfs => 1);
$lockmgr->lock("/some/file") || die "cant lock /some/filen";
$lockmgr->trylock("/some/file");
$lockmgr->unlock("/some/file");
$lockmgr->configure(-nfs => 0);
# Using lock handles
my $lock = $lockmgr->lock("/some/file");
$lock->release;
This simple locking scheme is not based on any file locking system calls such as flock() or lockf() but rather relies on basic file system primitives and properties, such as the atomicity of the write() system call. It is not meant to be exempt from all race conditions, especially over NFS. The algorithm used is described below in the ALGORITHM section.
It is possible to customize the locking operations to attempt locking once every 5 seconds for 30 times, or delete stale locks (files that are deemed too ancient) before attempting the locking.

Fcntl 5.8.8
Fcntl is a Perl module to load the C Fcntl.h defines. more>>
Fcntl is a Perl module to load the C Fcntl.h defines.
SYNOPSIS
use Fcntl;
use Fcntl qw(:DEFAULT :flock);
This module is just a translation of the C fcntl.h file. Unlike the old mechanism of requiring a translated fcntl.ph file, this uses the h2xs program (see the Perl source distribution) and your native C compiler. This means that it has a far more likely chance of getting the numbers right.
NOTE
Only #define symbols get translated; you must still correctly pack up your own arguments to pass as args for locking functions, etc.
EXPORTED SYMBOLS
By default your systems F_* and O_* constants (eg, F_DUPFD and O_CREAT) and the FD_CLOEXEC constant are exported into your namespace.
You can request that the flock() constants (LOCK_SH, LOCK_EX, LOCK_NB and LOCK_UN) be provided by using the tag :flock. See Exporter.
You can request that the old constants (FAPPEND, FASYNC, FCREAT, FDEFER, FEXCL, FNDELAY, FNONBLOCK, FSYNC, FTRUNC) be provided for compatibility reasons by using the tag :Fcompat. For new applications the newer versions of these constants are suggested (O_APPEND, O_ASYNC, O_CREAT, O_DEFER, O_EXCL, O_NDELAY, O_NONBLOCK, O_SYNC, O_TRUNC).
For ease of use also the SEEK_* constants (for seek() and sysseek(), e.g. SEEK_END) and the S_I* constants (for chmod() and stat()) are available for import. They can be imported either separately or using the tags :seek and :mode.
Please refer to your native fcntl(2), open(2), fseek(3), lseek(2) (equal to Perls seek() and sysse

SimpleCDB - A Perl-only Constant Database.
SYNOPSIS
use SimpleCDB;
# writer
# - tie blocks until DB is available (exclusive), or timeout
tie %h, SimpleCDB, db, O_WRONLY
or die "tie failed: $SimpleCDB::ERRORn";
$h{$k} = $v;
die "store: $SimpleCDB::ERROR" if $SimpleCDB::ERROR;
untie %h; # release DB (exclusive) lock
# reader
# - tie blocks until DB is available (shared), or timeout
tie %h, SimpleCDB, db, O_RDONLY
or die "tie failed: $SimpleCDB::ERRORn";
$v = $h{$i};
die "fetch: $SimpleCDB::ERROR" if $SimpleCDB::ERROR;
untie %h; # release DB (shared) lock
This is a simple perl-only DB intended for constant DB applications. A constant DB is one which, once created, is only ever read from (though this implementation allows appending of new data). That is, this is an "append-only DB" - records may only be added and/or extracted.
Course-grained locking provided to allow multiple users, as per flock semantics (i.e. write access requires an exclusive lock, read access needs a shared lock (see notes below re. perl < 5.004)). As (exclusive) updates may be take some time to complete, shared lock attempts will timeout after a defined waiting period (returning $! == EWOULDBLOCK). Concurrent update attempts will behave similarly, but with a longer timeout.
The DB files are simple flat files, with one record per line. Records (both keys and values) may be arbitrary (binary) data. Records are extracted from these files via a plain linear search. Unsurprisingly, this search is a relatively inefficient operation. To improve extraction speed, records are randomly distributed across N files, with the average search space is reduced by 1/N compared to a single file. (See below for some example performance times.) One advantage of this flat file based solution is that the DB is human readable (assuming the data is), and with some care can be edited with a plain ol text editor.
Finally, note that this DB does not support duplicate entries. In practice, the first record found matching a given key is returned, any duplicates will be ignored.

This is a little project I started to practice my OpenGL skillz. My inspiration was Ambient Flocks, which I liked so much I decided to try to clone it for Linux.
Since I did this mostly from memory (I only saw it in action once about a year ago), Im not sure how well I did, but Im happy with my final product anyway.

Firefox Showcase 0.9.3.2
Firefox Showcase is an extension that provides a new way to manage tabs and windows by showing them as thumbnails. more>>
Firefox Showcase is an extension that provides a new way to manage tabs and windows by showing them as thumbnails in a single window, tab or sidebar.
Includes a find bar that will filter the thumbnails, and the capability to select the thumbnails in the same way you would select files in your system.
Main features:
- Support for Firefox 2 beta 2.
- "Only current tabs" mode: toggle with CTRL+U. Will show only the current tab of each window. Can be enabled by default.
- Added selection area, making it easier to select thumbnails with the mouse. Works exactly as any file manager.
- Thumbnail caching. If enabled, a small capture of the different tabs will be cached, and used by Showcase when invoked. Disabled by default, can be enabled in the "Advanced" settings tab.
- Full screen plugins are now detected, and will show an icon instead of trying to render the thumbnail. Specific icons have been added for PDF, Quicktime and Flash. Other plugins show a generic plugin icon.
- Showcase can now be invoked using Firefox command line ("firefox -showcase"). This is useful when used together with an automation tool like AutoHotKey (http://www.autohotkey.com).
- Added option to hide the tab bar while using Showcase sidebar.
- Find bar state is now synchronized in Showcase tab, so its not possible to have 2 find bars at the same time. Can be disabled if necessary.
- Added new contextual menu actions: Showcase This Window, Duplicate Tab In New Window, Move Tab To New Window and Page Info.
- Added message when no thumbnails are being shown.
- All Showcase instances are updated when configuration is changed.
- Better support for custom themes. Also, looks better in Flock.
- Fixed IE Tab detection (was not working in 0.7.0).
- Improved close tab code. Focus in Showcase window will be retained when closing thumbnails.
- Focus is retained when Showcase creates a new window (for duplicating or merging tabs).
- Added new option: "Set thumbnail as the current tab when mouse cursor is over it". If activated, and in sidebar mode, a thumbnail will be selected just hovering your mouse cursor in its thumbnail. Consider deactivating the "Close Showcase sidebar if a thumbnail is opened" option if used.
- Added an independent version of Showcase for SeaMonkey ("SeaMonkey Showcase"). Also, solved the configuration panel problem, and the contextual menu actions that were not working.
- Solved Showcase sidebar title cosmetic bug when statistics where activated.
- Fixed key shortcuts with modifiers bug.
- Change Showcase sub-menu position in the "View" menu. Now its located under the "Sidebar" sub-menu.
- Added id attribute to menu items.
- If a thumbnail is focused, scroll will adjust automatically to show that thumbnail completely.
- In find bar, cursor and page keys can be used to scroll the thumbnail area.
- Added locales for Dutch (nl-NL, by Mark Heijl)and Hungarian (hu-HU, by Bernat Peter).

PasswordMaker 1.6.2
PasswordMaker is a small, lightweight, free, extension for Internet Explorer, Firefox, Mozilla, Netscape, Flock. more>>
PasswordMaker project is a small, lightweight, free, extension for Internet Explorer, Firefox, Mozilla, Netscape, Flock, and Yahoo! Widgets which creates unique, secure passwords that are very easy for you to retrieve but no one else. Nothing is stored anywhere, anytime, so theres nothing to be hacked, lost, or stolen.
How It Works:
You provide PasswordMaker two pieces of information: a "master password" -- that one, single password you like -- and the URL of the website requiring a password. Through the magic of one-way hash algorithms, PasswordMaker calculates a message digest, also known as a digital fingerprint, which can be used as your password for the website.
Although one-way hash algorithms have a number of interesting characteristics, the one capitalized by PasswordMaker is that the resulting fingerprint (password) does "not reveal anything about the input that was used to generate it." In other words, if someone has one or more of your generated passwords, it is computationally infeasible for him to derive your master password or to calculate your other passwords. Computationally infeasible means even computers like this wont help!

Log::Dispatch::File::Alerts 1.00
Log::Dispatch::File::Alerts is a Perl object for logging to alert files. more>>
Log::Dispatch::File::Alerts is a Perl object for logging to alert files.
SYNOPSIS
use Log::Dispatch::File::Alerts;
my $file = Log::Dispatch::File::Alerts->new(
name => file1,
min_level => emerg,
filename => Somefile%d{yyyy!!!!}.log,
mode => append );
$file->log( level => emerg,
message => "Ive fallen and I cant get upn" );
ABSTRACT
This module provides an object for logging to files under the Log::Dispatch::* system.
This module subclasses Log::Dispatch::File for logging to date/time stamped files. See Log::Dispatch::File for instructions on usage. This module differs only on the following three points:
alert files
This module will use a seperate file for every log message.
multitasking-safe
This module uses flock() to lock the file while writing to it.
stamped filenames
This module supports a special tag in the filename that will expand to the current date/time/pid.
It is the same tag Log::Log4perl::Layout::PatternLayout uses, see Log::Log4perl::Layout::PatternLayout, chapter "Fine-tune the date". In short: Include a "%d{...}" in the filename where "..." is a format string according to the SimpleDateFormat in the Java World (http://java.sun.com/j2se/1.3/docs/api/java/text/SimpleDateFormat.html). See also Log::Log4perl::DateFormat for information about further restrictions.
In addition to the format provided by Log::Log4perl::DateFormat this module also supports $ for inserting the PID and ! for inserting a uniq number. Repeat the character to define how many character wide the field should be.
A note on the !: The module first tries to find a fresh filename with this set to 1. If there is already a file with that name then it is increased until either a free filename has been found or it reaches 9999. In the later case the module dies.
