Free subtle software for linux

Subtle application is a another tiling window manager with a slightly different approach to place the windows, in contrast to other tiling window managers like Wmii or Ion. The placement in subtle is done by tiling windows which arrange every child-window either in a horizontal or a vertical manner. Client or even tiling windows can be moved/dragged into a tile and will be arranged according to the tile type. Every window can be swapped too and shaded inside of it’s parent tile. (view)

This behaviour is mostly inspired by Wily, an emulation of ACME – the well-known Plan9 “editor”.

Configuration and theming is done with the help of Lua. Furthermore there is an extendable “statusbar” attached to the main tile. Sublets, small Lua scripts, provide features like a customizable clock or even a small progressbar for the battery capacity of a notebook.

The initial code was based on Aewm, but is meanwhile completely re-written.
Simplicty and flexibility are the goals of this project – besides not to be bloated of course. Controlling can be done either with the mouse or the keyboard – just as the user prefers.

ZynAddSubFX is a opensource software synthesizer capable of making a countless number of instruments, from some common heared from expensive hardware to interesting sounds that youll boost to an amazing universe of sounds.
ZynAddSubFX project started in March 2002, and I had written it because I wish to make a synthesizer that produces very beautiful sounds, but which is freely available to anybody who needs it.
Main features:
- realtime synthesizer
- polyphonic (allows playing more than one note at once), mutlitimbral (allows playing more than one instrument at once) synth
- Microtonal capabilities with any scale, any number of notes per octave (well... the no. of notes per octave must be less than 128) and keymapping
- 3 synthesiser engines: 1) first (called "ADsynth" or "ADnote") is a complex engine which makes sounds by adding a number of voices. Each one has filters, envelopes, LFOs, morphing, modulation (Ring Modulation, Phase Modulation... the modulators can have any shape), resonance, etc. Each voice includes a very powerful waveform generator with up to 128 sine/nonsine harmonics. You can use Fourier synthesis or if you dont like it you can waveshaping/filtering of functions. This engine includes antialiasing.
- 2) second (called "SUBsynth" or "SUBnote") is a simpler engine who allows to make sounds by subtraction of harmonics of sounds from white noise
- 3) third (called "PADsynth" or "PADnote") is engine that makes very beautifull pads and other instruments.
- Instruments can be orgainzed in kits, which alows you to make drum kits or layered(mixed) instruments; this makes possible to use more than one instrument for a single part. It is possible to choose what items from the kit should be processed by the Parts effects.
- Effects: Reverb, Echo, Chorus/Flange, Phaser,AlienWah (its a kind of vocal morpher), Distorsion(Waveshaping), EQ, DynamicFilter
- The effects can behave as System Effects or as Insertion Effects; this allows to use many effects at the same time. You can put any insertion effect on any part(or more insertion effects to same parts, if you like so) or you can put the insertion effect to Master output (very usefull if you use the EQ effect). Also, you can have instruments effect (that is saved with the instrument).
- Filters up to 60dB/octave (or more..); filters can be analogic (LPF,HPF, BPF,etc.), formant(advanced formant filters) and state variable (SVF)
- Envelopes can have ADSR (or ASR, etc..) modes or can be free modes (with any shape)
- Many settings has a "randomness" option, which you can make instruments that every time produces a subtle different sound; this produces a very pleasent effect (like analogue synths or natural instruments that cant produces exactly same sound twice). Because of this, even if it is digital synthesis, it sounds "warm". Listen the ogg vorbis demos from this page to hear this effect.
- the specifications can be easily chaged, so (for example) if you want to change the number of voices or parts to a higher value or to allow a higher number of effects at the same time, there is necessary to chage only a single value from the source file (globals.h) and to recompile the program
- Intuitive and easy to use User Interface with Clipboard and many objects has user presets
- Midi support (supports many controllers) and (if you want) JACK support
- the program has Virtual Keyboard which let you to use it even if you dont have a real midi keyboard
- the graphical user interface can be completely disabled if the user need so
- it is a free program, licensed under version 2 of the GNU General Public License
- there are over 300 high quality instruments included into the package
- many other features.... It is is impossible to describe all this programs features in just a page
Enhancements:
- made to work with mxml-2.2 (will NOT work on older versions)
- it is possible to remove completely the graphical user interface (e.g. it can run without X). For this you need to modify the DISABLE_GUI option from the Makefile.inc
- added a commandline -L which load a instrument (.xiz) - now it only loads to part 0 (you can use this option with -l to load a master file and after this the option -L to replace the part)

Borealis provides a "better feel" through use of the subtle aural notifications.
The goal of this sound theme is to provide "better feel" through use of the subtle aural notifications. The test I always have in my mind while designing the desktop sounds is to imagine having half-dozen (or more) computer stations in the same office or studio and consider whether their simultaneous use (and resulting desktop sounds) would pose as distraction on users and their productivity. Therefore, in order to minimize the "distraction factor" this theme associates many of the common desktop events with brief, mostly non-pitched, but nonetheless pleasing sound sources (a.k.a. effects).
All of the sounds included have been composed (if applicable), recorded, and mastered by me (although a few of them bear resemblance to other OSs sounds). Some of them are leftovers from my previous compositional and production endeavors, while others are entirely new creations.
All sounds are designed and mixed at CD-quality (stereo, 16-bit, 44.1KHz). Ogg version is distributed as 192Kbit stereo files.
Main features:
- Includes sounds for:
- KDE WM
- KDE System Notifications
- Kdevelop
- Kopete
- KDE Sysguard
- KMail
- Konsole
- Proxy configuration
- K3b (missing 1 sound)
- 4 startup sounds
- 2 exit sounds
- Automated installer and uninstaller
Enhancements:
- Couple improvements to the install and uninstall scripts (thanks to Kirk Strauser for the heads-up!)

THCcalc program was originally written for Un*x-type systems. That current branch is still accessible and will occasionally be updated. This old code is in C and under a BSD license. This does not apply for the new code.

The program calculates the THC content in a persons blood based on their usage pattern over a specific period of time.

It is text based and menu driven at the moment. It will be both a command-line utility and an emacs package when finished. The new code is in LISP (currently common lisp only).

The old version of the code has several subtle bugs which should not affect usability but could cause an issue for some users. This is why I recommend the lisp version. Many Linux distributions come with a lisp interperter or can easily get one. When the emacs verion of the program is complete you should have no problem using this on any *nix system as emacs is "almost" universal.

This program will offer many advantages over the program it was written to replace (the original THC Calculator not the previous version of this code) including: date association, data files, database management, and daily output that can be used to drive a graph or other database. It can also be configured based on how paranoid a person is by lowering the cutoff rate or even the rate of decay.

File::Find is a Perl module to traverse a directory tree.

SYNOPSIS

use File::Find;
find(&wanted, @directories_to_search);
sub wanted { ... }

use File::Find;
finddepth(&wanted, @directories_to_search);
sub wanted { ... }

use File::Find;
find({ wanted => &process, follow => 1 }, .);

These are functions for searching through directory trees doing work on each file found similar to the Unix find command. File::Find exports two functions, find and finddepth. They work similarly but have subtle differences.

find

find(&wanted, @directories);
find(%options, @directories);

find() does a depth-first search over the given @directories in the order they are given. For each file or directory found, it calls the &wanted subroutine. (See below for details on how to use the &wanted function). Additionally, for each directory found, it will chdir() into that directory and continue the search, invoking the &wanted function on each file or subdirectory in the directory.

finddepth

finddepth(&wanted, @directories);
finddepth(%options, @directories);

finddepth() works just like find() except that is invokes the &wanted function for a directory after invoking it for the directorys contents. It does a postorder traversal instead of a preorder traversal, working from the bottom of the directory tree up where find() works from the top of the tree down.

B::Concise is a Perl syntax tree, printing concise info about ops.

SYNOPSIS

perl -MO=Concise[,OPTIONS] foo.pl

use B::Concise qw(set_style add_callback);

This compiler backend prints the internal OPs of a Perl programs syntax tree in one of several space-efficient text formats suitable for debugging the inner workings of perl or other compiler backends. It can print OPs in the order they appear in the OP tree, in the order they will execute, or in a text approximation to their tree structure, and the format of the information displayed is customizable. Its function is similar to that of perls -Dx debugging flag or the B::Terse module, but it is more sophisticated and flexible.

EXAMPLE

Heres an example of 2 outputs (aka renderings), using the -exec and -basic (i.e. default) formatting conventions on the same code snippet.

% perl -MO=Concise,-exec -e $a = $b + 42
1 enter
2 nextstate(main 1 -e:1) v
3 gvsv[*b] s
4 const[IV 42] s
* 5 add[t3] sK/2
6 gvsv[*a] s
7 sassign vKS/2
8 leave[1 ref] vKP/REFC

Each line corresponds to an opcode. The opcode marked with * is used in a few examples below.

The 1st column is the ops sequence number, starting at 1, and is displayed in base 36 by default. This rendering is in -exec (i.e. execution) order.

The symbol between angle brackets indicates the ops type, for example; < 2 > is a BINOP, < @ > a LISTOP, and < # > is a PADOP, which is used in threaded perls. (see "OP class abbreviations").

The opname, as in add[t1], which may be followed by op-specific information in parentheses or brackets (ex [t1]).

The op-flags (ex sK/2) follow, and are described in ("OP flags abbreviations").

% perl -MO=Concise -e $a = $b + 42
8 leave[1 ref] vKP/REFC ->(end)
1 enter ->2
2 nextstate(main 1 -e:1) v ->3
7 sassign vKS/2 ->8
* 5 add[t1] sK/2 ->6
- ex-rv2sv sK/1 ->4
3 gvsv(*b) s ->4
4 const(IV 42) s ->5
- ex-rv2sv sKRM*/1 ->7
6 gvsv(*a) s ->7

The default rendering is top-down, so theyre not in execution order. This form reflects the way the stack is used to parse and evaluate expressions; the add operates on the two terms below it in the tree.

Nullops appear as ex-opname, where opname is an op that has been optimized away by perl. Theyre displayed with a sequence-number of -, because they are not executed (they dont appear in previous example), theyre printed here because they reflect the parse.

The arrow points to the sequence number of the next op; theyre not displayed in -exec mode, for obvious reasons.

Note that because this rendering was done on a non-threaded perl, the PADOPs in the previous examples are now SVOPs, and some (but not all) of the square brackets have been replaced by round ones. This is a subtle feature to provide some visual distinction between renderings on threaded and un-threaded perls.

Transcend Game project is a retro-style, abstract, collage-building, musical, shooter game.
The graphics are geometrical, and the pace is sometimes frenzied. Two features set Transcend apart from other games.
First, its dynamic graphical engine, which can smoothly morph from one complex shape to another in realtime, produces striking displays.
Combining these dynamic shapes with subtle randomizations ensures that each new play through a level is visually different from the last.
The second novel feature is the musical power-up system.
As you play through a level, you are simultaneously assembling an abstract visual collage and arranging a unique piece of music.
Enhancements:
- Fixed bugs that caused post-explosion fade factors to become negative, which in turn caused boss explosions to linger on some platforms.
- Fixed zoom behavior when strafing.
- Added fade-in when enemies are created to avoid a visual pop-in.
- Added smooth turning when enemies switch targets.
- Changed so that pieces can be picked up while they are moving as a result of enemy fire. This makes pick up less confusing and frustrating.
- Made bullet fade-out smoothly at end of range to avoid visual pop.
- Doubled piece pick-up radius to make picking up pieces easier.
- Fixed jerky piece pick-up and drop.
- Added mini-explosion graphics to indicate when damage is being done to boss. These graphics also change color to indicate the boss health.

Thin FTP Upload project is an FTP upload applet designed for integration with Web applications.
Do you want to quickly add FTP file upload functionality to your website? Then Thin FTP Applet, a product that can be installed in less than 2 minutes is the product to choose.
To send files using the File Transfer Protocol, all your users have to do is to drag and drop them onto the designated area of the browser. Entire directory tree and a virtually unlimited number of files totalling several giga bytes can be transfered in this manner.
If your server is configued to allow annoymous transfers your users dont even have to login. Else they can login interactively by entering their username and password. Or else you can make it easier for them by using a single predefined username and password for each user so that multiple accounts do not have to be created.
Whats New in 1.02 Stable Release:
- The new version of the applet aims for improved compatibility with a wider range of FTP servers, epecially those servers deployed on Windows.
- The new version includes a subtle change in the way that the applet handles the trailing slash in the URL.
Whats New in 2.0 Development Release:
- Interrupted FTP uploads can now be resumed.
- A new progress monitor has been added.
- The applet loading mechanism has been changed, and the applet can now be configured using HTML parameters.
