Free watching software for linux

mswatch project is a command line unix program that keeps two mailboxes synchronized more efficiently and with shorter delays than periodically synchronizing the two mailboxes.
mswatch watches mailboxes to know when to initiate mailbox syncs. Using mswatch, your mail synchronization program can be called on demand instead of through polling, resulting in prompter mail delivery and lower bandwidth usage and server load.
mswatch is designed to work in conjunction with mailbox synchronization programs, currently supports watching Linux (2.4+) hosted Maildirs (including Maildir folders, Maildir++), and is licensed under the GNU GPL. Future support for additional mailbox formats, especially for mbox, is planned.
Why mswatch
Keeping a set of mailboxes on multiple computers means keeping the copies synchronized (eg on ones desktop and laptop or on a personal computer that can not be reached while on the road an always-reachable server). While the IMAP protocol is designed to support this and is widely used, IMAP clients can only detect mailbox changes by querying the server.
Thus clients generally either sync when the user requests or sync periodically. However, because each mailbox sync uses server and network resources and because users often have a number of mailboxes, many of which receive mail infrequently, one must compromise between prompt message delivery and low server and network resource usage. Typical practice is to sync only when the user requests or to sync periodically with 5-10 minute frequencies. Nonetheless, it is often helpful for users to see new mail fairly soon after its arrival (eg notifications, group meeting changes, or active conversation threads).
mswatch addresses this speed of delivery vs resource usage tradeoff using interrupt-based instead of polling behavior to detect mailbox changes. mswatch asks each of the two mailstores to send mailbox change notifications; when mswatch receives a notification it in turn invokes the users mailbox synchronization program for the changed mailbox. Thus, idle mailboxes do not use active resources and prompt mailbox synchronization is efficient.
Version restrictions:
- Because mswatch abstracts mail changes and synchronization to the mailbox (instead of message) level and because mail watcher communication is one-way, extra mailbox syncs occur. While it would be great to avoid this extra work, it is in the noise compared to the number of empty syncs that polling accumulates.
For example, the case of new mail delivered to the mail servers INBOX:
(1) mswatch detects the changed server INBOX
(2) mswatch invokes the mail syncer for INBOX, which adds the mail to the local INBOX
(3) mswatch detects the changed local INBOX
(4) mswatch invokes the mail syncer for INBOX, which detects no changes
Thus two syncs occur in this case instead of the single necessary sync.
Enhancements:
- Per-mailbox inter-sync delays were added to rarely sync high volume mailboxes and quickly sync important mailboxes.
- Inter-sync delays are allowed to be greater than the maximum error delay.
- mswatch now prints the names of pending mailboxes upon receiving SIGUSR1.

loadwatch project allows a single child process to run only when the load on a machine is within certain bounds. When the machines load passes the high load mark, then the child process is stopped.

The process is only restarted when the machines load drops below the low load mark. The load is checked at a user definable interval. loadwatch is distributed under the GNU GPL.

Usage:

loadwatch [-d < time>] [-h < load>] [-l < load>] [-n < copies] [-p < pid>] [-- < command>]
-d < int> load sampling interval (10 seconds)
-h < float> high load mark (1.25)
-l < float> low load mark (0.25)
-n < copies> number of children to fork (1)
-u < filename> file that will be used to externally control a
loadwatch process.
-p < pid> pid of process to control (loadwatch will actually
send signals to the group containing this pid)
NOTE: -p and < command> are mutually exclusive, but one has to be
specified.

Example:

loadwatch -d 10 -h 1.25 -l .25 -- ./rc5des

which means: check the load every 10 seconds, stop rc5des when the load is
greater than 1.25 and restart rc5des when the load drops to .25.

lw-ctl < filename> < cmd>
< filename> is the control file, this corresponds to a unix domain
socket.
< cmd> is the command to send to the loadwatch process.
RUN -> put loadwatch into RUN mode, that is the child process
runs regardless of the load.
STOP -> put loadwatch into STOP mode, that is, the child
process will not run regardless of the load.
WATCH -> WATCH mode, the normal load watching mode.

Example:

lw-ctl ./fooey RUN

Causes the loadwatch process (if it was started with "-u ./fooey") to go
into RUN mode. you could put lw-ctl in a cron job that runs in the
morning to put the job in STOP mode and then again in the evening to put
the job back into WATCH mode.

The children which loadwatch forks are all part of the same process group.
loadwatch stops and starts the processes by signalling the process
group with SIGSTOP and SIGCONT respectively.

Send suggestions and bug reports to . if you do anything
interesting with loadwatch, let me know. i use it for controlling the
distributed.net clients, but i figure itd be good to control thinks like
crack as well.

Play What I Mean project allows a user to, from a single commandline or terminal, enter a string, or list of strings, that represent what he/she wishes to have played by whatsoever media player he chooses, the default being MPlayer, and then having that particular item be found and played.
What this essentially means is that if I were to have a sudden hankering to listen to a particular song or video, lets say Ice Pick by The Pillows, which happens to be the song to a particular music video that I enjoy watching. Under the traditional methods of video viewing I would be stuck with two potential courses of action for playing this particular file:
- Change directories several times to that one folder somewhere that I "know" its in, or
- Point and Click my mouse until I find that same directory and then search through what could be countless files to find it.
Each of these prospective choices have their own inherent difficulties and ire. Using the commandline often requires alot of typing to arrive at the desired directory, often times nestled deep within the tree.
Once there your problems only multiply by the number of files you actually store in your "media" folder, try ls | moreing through a heavily populated folder looking for the name of that file you wanted to play sometime, it isnt too fun and further is a waste of my valuable time.
You may be thinking at this point that the second option, the graphical one, must be easier since its exciting, full of pictures, and frankly novel, I disagree. I may not be the best judge on this matter, seeing as how I cant see out of my right eye however, I feel that scanning through a large folder, or folders, full of files is quite a strain on the vision, and more importantly an unnescesary burden on what should be a simple matter.
Main features:
- Nestable Playlist support
- Multi-string arguments
- Transparent command option passing
- Cache for faster access of frequently played files
- Graphical configure

Trailerfetcher is video conversion application.

As an owner of a small home-cinema system I got an idea: Wouldnt it be neat if before every film you play, mythtv would automatically show you a few trailers of other cool films too come (or already there)?

Trailers would also allow you to "ease into" actually watching the film and cover the whole "lets get the popcorn"-phase, etc.

But I already knew what a hassle it is to download _one_ trailer from sites like yahoo or apple.com. So I decided to make it easy:

This application provides an easy to use interface for downloading trailers. It fetches a list from a trailerpage (currently only yahoo.com) and lists all avalible trailers.

It then summarize the found trailers and displays info about the title, the genre and a short describtion of the plot. All this is fetched and extracted automatically.

You can than mark the trailers you want to download and simply press "Download" to save them to your harddrive.

Ok this was the marketing talk. I wrote this software because I needed it (probably the reason for most open-source-projects), but it is far from feature-complete. It is usable though (it loaded all 73 currently avalible trailers from yahoo.com last night).

AFAIK it is perfectly legal to download these trailers. If anyone thinks it isnt: please feel free to delete the project.

Usage notes: Set the settings before retrieving the list! Some settings (e.g. the resolution) will not take effect if you dont.
