Free twilight stuff software for linux

cpulimit is a simple program that attempts to limit the cpu usage of a process (expressed in percentage, not in cpu time). This is useful to control batch jobs, when you dont want they eat too much cpu.

cpulimit project does not act on the nice value or other scheduling priority stuff, but on the real cpu usage. Also, it is able to adapt itself to the overall system load, dynamically and quickly.

LMMS is a project trying to create a gui for TV that can be used with a gamepad/joystick. In future there shall be various applications for playing audiofiles (Ogg-Vorbis, MP3, WMA, CD etc) and videofiles (DivX, MPEG, DVD, TV etc). Games and other stuff (recording TV etc) are planed too.

For now the whole project is written in python/pygame and there are some applications available:

Menu - for choosing another application
Image-Viewer - as the name says, it will allow you to watch some images
CD-Player - for playing Audio-CDs
Audio-Player - with support for Ogg and MP3

Actually the following gamepads/joysticks are supported:

Gravis Gamepad Pro
Microsofts X-Box pad
Nintendos SNES pad

The mii-tool command provides an tool for checking and setting ethernet cabling parameters.
It is normally included in Bernd Eckenfels net-tools package, but this is an single distribution which only contains mii-tool. This package also comes with cleaned makefile and allows build-time relocation and cross/sysroot-compiling.
Enhancements:
- removed evrything whats not mii-tool
- removed I18N stuff
- added support for specifying an installation root via the DESTDIR environment variable
- removed the config stuff (not needed for mii-tool)

kfilewatcher project watches for file changes and allows you to react on them.

Example:

kfilewatcher /tmp/test 2>&1 | while read a; do echo "File has changed - doing something"; done

This command does something every time kfilewatcher detects a change. At the moment, the only action is to output "File has changed - doing something", but you can write anything there, e.g.

- backup stuff as soon as it changes
- publish files on your homepage everytime they change
- keep directories in sync

PHAT is a browser-based network management solution with a heavy lean toward switches, routers, and other traffic handlers which can be used to control either a single node, subnet, or vlan.
As you can probably see if youre reading this, PHAT is not the worlds most useful tool... yet. The reason I released this code in the first place was because I found myself in a vicious cycle: I didnt want to release the code until it was a little cleaner, a little more useful, and less dependent on site-specific stuff (currently, PHAT is quite reliant on NIS for example). However, I really havent had all the time in the world to devote to coding (Im also a sys/network admin), so getting PHAT to this presentable state has been tough (obviously, as I still dont consider it very presentable). I realized the only way to be useful was if I just released it for better or worse, and let people have at it.
Right now, the only things PHAT can really do depend on NIS, and MySQL. However, the NIS stuff should go away soon, and its not very hard to understand whats happening. Anyone with a decent level of networking and PHP expertise should be able to rip out the NIS stuff and replace it, or abstract the stuff altogether. The MySQL stuff will go away too, but not tomorrow or next week. As more people get involved who have more experience in dealing with ADODB or the PEAR DB stuff well move toward one of those.
In addition to reading this file, you really should read the source files as well, as I have a tendency to write really verbose stuff in there.
So, in a nutshell, I picked the release name "pseudocode" because thats exactly what PHAT currently is. Its a proof of concept. Everything has been done in a very brute force manner and has been tested just enough that theres some evidence that this stuff can work and I can demo it for a few interested local parties :)
At this stage in the game, ideas reign supreme. The only thing that rules over talking about ideas is coding prototypes for them.
Enhancements:
- PHP 4.x: As far as I know, any 4.x version works. I always use the latest version of PHP, and the version I used initially was 4.1x, I dont exactly remember which one.
-
- Apache: This has only ever been tested on Apache. UNIX/Linux: PHAT, at this stage, still makes a couple of systemcalls that are *nix specific. Its been tested on Linux and
- Solaris. This dependency should eventually go away.
-
- NIS: This dependency really has to go away. Abstracting the things PHAT uses NIS for right now is the first order of business.
-
- MySQL: I want to use the PEAR or ADODB stuff, but havent been overjoyed with either one. I dont want to have PHAT be dependent on any one database.

What I wanted was something lightweight and flexible, a simple way to carry and maintain my tasks around on a USB stick.

The program needed to be capable of running on different platforms and must not depend on any data format or any web connection.

yaGTD incorporates major features from Allens Getting Things Done philosophy and notion of urgency and importance preached by Stephen Covey (cf Seven Habits of Highly Effective People book).

To resume, if you are comfortable at the command line a simple plain text is an age-old but perfect method for tracking your stuff, and yaGTD can help you to manage efficiently this file.

The project is released under the GPL so anyone can try it and make their own modifications.

DateTime::Astro::Sunrise is a Perl DateTime extension for computing the sunrise/sunset on a given day.

SYNOPSIS

use DateTime; use DateTime::Astro::Sunrise; ^

my $dt = DateTime->new( year => 2000,
month => 6,
day => 20,
);
my $sunrise = DateTime::Astro::Sunrise ->new(-118,33,undef,1);
my ($tmp_rise, $tmp_set) = $sunrise->sunrise($dt);

This module will return a DateTime Object for sunrise and sunset for a given day.

USAGE

my $sunrise = DateTime::Astro::Sunrise -new(longitutide,latatude,ALT,Iteration);>
inter is set to either 0 or 1. If set to 0 no Iteration will occur. If set to 1 Iteration will occur. Default is 0.
There are a number of sun altitides to chose from. The default is -0.833 because this is what most countries use. Feel free to specify it if you need to. Here is the list of values to specify altitude (ALT) with:

0 degrees

Center of Suns disk touches a mathematical horizon

-0.25 degrees

Suns upper limb touches a mathematical horizon

-0.583 degrees

Center of Suns disk touches the horizon; atmospheric refraction accounted for

-0.833 degrees

Suns supper limb touches the horizon; atmospheric refraction accounted for

-6 degrees

Civil twilight (one can no longer read outside without artificial illumination)

-12 degrees

Nautical twilight (navigation using a sea horizon no longer possible)

-15 degrees

Amateur astronomical twilight (the sky is dark enough for most astronomical observations)

-18 degrees

Astronomical twilight (the sky is completely dark)

Notes on Iteration

The orginal method only gives an approximate value of the Suns rise/set times. The error rarely exceeds one or two minutes, but at high latitudes, when the Midnight Sun soon will start or just has ended, the errors may be much larger. If you want higher accuracy, you must then use the iteration feature. This feature is new as of version 0.7. Here is what I have tried to accomplish with this.

a) Compute sunrise or sunset as always, with one exception: to convert LHA from degrees to hours, divide by 15.04107 instead of 15.0 (this accounts for the difference between the solar day and the sidereal day.
b) Re-do the computation but compute the Suns RA and Decl, and also GMST0, for the moment of sunrise or sunset last computed.
c) Iterate b) until the computed sunrise or sunset no longer changes significantly. Usually 2 iterations are enough, in rare cases 3 or 4 iterations may be needed.

($sunrise, $sunset) = $sunrise->($dt);

Returns two DateTime objects sunrise and sunset. Please note that the time zone for these objects is set to UTC. So dont forget to set your timezone!!
