Free sep 2 software for linux

QGolf is a project that simulates the transmission of a signal on a rope.

QGolf was developed for radio amateurs to clarify the behaviour of a signal on an antenna.

It demonstrates the forces that act on a rope if you move one end of it: you can see how waves are reflected, how resonance occurs, and how multiple pulses coexist on the same rope.

Various parameters can be updated during the simulation.

Smartmenu is a menuing application for Lirc. Its purpose is to make use of an infra-red remote controller with a Linux box as easy and smart as possible.
It handles displaying and browsing menus in a way that is usable for typical user of a remote controller.
Such a user must be able to use the menus when he is a few meters away from the monitor or even with monitor turned off.
Enhancements:
- This release provided better control of lirc key repeating.

The NIST Implementation of the Ad-Hoc On Demand Distance Vector protocol is a kernel-level driver for Linux . AODV is a routing protocol for ad hoc networks designed with mobile wireless devices in mind. For a quick overview on AODVs basics, check out our Quick Guide to AODV page. If you are interested in running a simulation of AODV, NIST has developed a simulation in OPNET.
Kernel AODV is a loadable kernel module for Linux. It implements AODV routing between computers equipped with WLAN interfaces.
This software was developed at the National Institute of Standards and Technology by employees of the Federal Government in the course of their official duties. Pursuant to title 17 Section 105 of the United States Code this software is not subject to copyright protection and is in the public domain. Kernel AODV is an experimental system. NIST assumes no responsibility whatsoever for its use by other parties, and makes no guarantees, expressed or implied, about its quality, reliability, or any other characteristic. We would appreciate acknowledgement if the software is used.
This software can be redistributed and/or modified freely provided that any derivative works bear some notice that they are derived from it, and any modified versions bear some notice that they have been modified.
Enhancements:
- Corrected LINK_LIMIT #ifdefs (Fix from Peter Barron)
- aodv_neigh.c
- hello.c
- module.c
- Add Packet Queuing back in (Fix from Peter Barron)
- Send queued messages when recieving a route, aodv_route.c
- Drop packet from queue if RREQ fails, rreq.c
- Added packet_queue.c back in, packet_queue.c
- Added init and cleanup of packet_queue, module.c
- Added additional check to packet_out.c to determine if packet is going to external subnet on a gateway.
- Shouldnt be neccesary since a route should be created for the external destination anyhow. Have to look into this. (Fix from Peter Barron)
- Removed annoying message printed when signal strength can not be read. Instead only prints when can not be set. signal.c
- Fixed the undefined symbol STRCHR problem for real this time. The problem is doing strstr() with a singlecharecter results in it being converted to strchr(), but for some reason it is not properly imported. The solution it to simply use stchr() instead. module.c
- Changed it so that find_aodv_route() will return valid routes that have expired. When it didnt return expired routes two routes would sometimes be created. Also, now kernel routes are only removed when an expired route is removed. find_aodv_route() will also invalidate expired valid routes.
- Had some trouble with duplicate kernel routes. Now we are always deleting before inserting a new route. Should fix it, fingers are crossed.
- Changed delete_neighbor() so that we send out an RERR even if the route is no longer valid. Also change gen_rerr() so that is will send out a RERR even if the route is not valid. It has to be better to send out a few extra rather than not enough. Just cause you have timed a route out doesnt mean others have.
- Compared the Metrics wrong in update_route() if the seq numbers were equal.

ModSecurity is an FREE and GPL lincesed software for intrusion detection and prevention engine for web applications.
Operating as an Apache Web server module, the purpose of ModSecurity is to increase web application security, protecting web applications from known and unknown attacks.
Enhancements:
- This version fixes the issue with subrequests, a problem with full-width Unicode encoding, and a few other small issues.
- It also bundles the most recent version of the Core Rules (which contains many improvements over the previous version) along with the updated documentation.

Rekall is a database front-end, somewhat in the style of MicroSoft Access. However, Rekall is not itself a database, and does not include a database.
By this we mean that data is stored somewhere else in an SQL server, and Rekall is fundementaly just a tool to extract, display and update that data (of course, it does lots more than that, it does forms and reports and scripting and .... you get the idea).
It is database agnostic, and does not have any preferred database in the sense that Access(tm) uses the Jet. database engine (although the Windows version can use the Jet database engine via an ODBC driver).
Rekall can do lots of the things that you would expect of a database front-end (or if it cant, let us know!). You can design and use forms and reports, you can construct database queries, and you can import and export data (actually, you can copy data, import is just copy file to table, and export is just copy table to file). You can also create reusable components which you can use in forms and reports, to reduce application development time.
Rekall can be scripted using the the Python language. You can arrange that a script is executed when various events occur (for instance, when the user changes the value of a control).
Scripts can be associated directly with the event, but you can also store scripts in script modules for more general use. And, of course, you have full access to all the modules that are available for Python. Plus, Rekall has an integrated Python debugger with syntax highlighting.
RekallRevealed is run as a community website to support the GPL version of Rekall. Rekall is being included by some of the Linux distributions, and commercial components and support are available from TotalRekall and from theKompany.
Enhancements:
Dynamic Layouts
- Dynamic layouts allow you to create forms where controls automatically resize depending on settings such as font sizes, and as the user resizes the form. This is based on QTs layout engine, althougn only a restricted set of functions are available.
Tool Boxes
- Personally, the author is not a fan of tool boxes, but they seem to be popular, so Rekall now supports them. If you still prefer the old context menu mechanism, you can turn tool boxes off.
Wizards
- Lots of the controls now have control wizards which prompt you for the important settings. Hopefully wizards will be avaialble for all controls by the time 2.3.x becomes 2.4.0
Stock Databases
- Stock databases. Rekall will come with some stock databases (actually there is only one at present, the demo database, but more will be added over time) which can be used to create your own database. In addition, you can download stock databases from the web. See the Rekall section on downloading the database that runs this website!
Manual
- The manual can now be accessed via a dedicated manual viewer (loosely modelled on QTs assistant program).
Other stuff
- Lots of bug fixes, lots of other smaller additions.
Enhancements:
- 2.2.6 is the now latest stable release.
- Mostly bug fixes since 2.2.4, particularly a problem related (I believe) to the default style used by Fedora Core 4

pBeans project is a Object/Relational (O/R) database mapping layer. It is designed to be simple to use and automated.
The idea is that you save time and effort by simply focusing on writing Java classes, and not worrying about maintenance of matching SQL scripts, schema evolution, XML based schemas, or generating code. The pBeans framework takes care of persisting JavaBeans with little assistance from the developer.
Main features:
- Automatic Table Creation and Schema Evolution- Tables corresponding to JavaBean classes are created on demand. Field types are based, by default, on JavaBean compile-time types. Field type changes and new fields are detected. Manually changing tables (user-managed mode) is also supported.
- Based on Annotated JavaBeans- You define a getter and setter for each bean property. Persisent bean classes only need to be tagged with a @PersistentClass annotation.
- Transitive Persistence- If object A is persisted and it refers to Persistent object B, then object B is automatically persisted. If Persistent object C also refers to B, and C is also persisted, the record for object B in the database is not duplicated.
- Instance Consistency- If you retrieve an object from persistent storage that is already known to exist in main memory, you get a reference to the object in main memory. (Garbage collection is allowed to happen via weak references.)
- Near-Zero Configuration- There is no need to define schemas or anything of the sort in a language other than Java, and there are no code generation steps of any kind. No XML or SQL need to be written, except the necessary to create a database and grant user permissions. However, you can instruct pBeans to let you manage database modifications manually.
- Database features- Transactions and auto-increment IDs (MySQL only) are now supported.
- Flexibility- Via annotations users are allowed to define their own table and field names, the name of the primary key, whether fields are nullable, whether tables are user-managed (not automatically modified), table indexes, unique or otherwise, whether unused fields should be deleted, whether a field is nullable, whether it is renamed from another field (to prevent loss of data when a property is renamed), etc.
- Servlet support- A pBeans store may be easily configured using servlet context parameters (see ServletAccess.)
