Free temporary software for linux

Disposable Temporary E-mail project provides the user with disposable e-mail addresses which expire after a certain time. The user can read and reply to e-mails that are sent to the temporary e-mail address within the given time frame.
Main features:
- Users can generate e-mail addresses
- Users can see their incoming e-mails
- Users can reply to e-mails
- Completely template driven
- Installation routine
How the script works:
With a click on a button the user generates a new e-mail address. That address will be stored in the database along with its creation time. The e-mail address is assigned to the user by a session cookie.
The user then uses the e-mail for any purpose where an e-mail address is required. Most commonly that will be some kind of registration.
In the background the script checks continuously for arriving e-mails. Once an e-mail that has been sent to a generated e-mail address arrives, the script displays it.

Better Weather contains a couple of scripts using normal KDE and Linux tools to provide better display of weather info than KDEs weather applet. It downloads the information from the US national weather service and maps from weather.com. Two launchers on the main menubar bring up the window separately. Full details and instructions are in the readme.

This is a solution that worked for me, not being a coder. You have to make it work for you. Its an idea and a set of tools. Its also US-centric, but someone may take the idea and make it work just as well anywhere. I hope someone finds it as useful as I do.

WHAT IT DOES

The tools I wrote are two *very* simple bash scripts. The script, localwx.sh, invokes the python weather utility, and downloads the current weather conditions and forecast in text format from the weather service. It stores the information temporarily in a text file (I chose the desktop as the directory in which to save it.) It then "reads" the text file into a kdialog box. When the "ok" button is clicked, the temporary file is deleted.

The other script, wxmap.sh, downloads a current local weather map image using wget, saves it temporarily to the desktop, and calls Kview to display it. When Kview closes, the temporary image file is deleted.

HOW I DID IT

The man pages for "weather," "kdialog," and "wget" were useful for determining which options to use. The script for weather forecasts has to be edited to receive the data for the users current location. My nearest airport is PDK, so my ID was "KPDK." The rest is straightforward enough. To make the weather map script work, you can go to weather.com or your local tv station website and copy the image location for the weather map they use. It can be pasted into the script.

Once the scripts were edited to suit, I made them executable (chmod +x filename), copied them to /usr/local/bin, and created a launcher for each in my main menubar. Describing the process is a lot more difficult than actually doing the work!

Tmpf is tiny script (written in Ruby) to write standard output to a temporary file, run an application with the name of that file as an argument, then delete the temporary file when done.

The project is useful when you want to pipe output to a program that only accepts files, not standard input. Example: cat myfile.ps | tmpf gv (equivalent to: gv myfile.ps). Despite the incredible simplicity of this script, there is nothing quite like it provided among the standard Unix tools.

tngCalendar is a Web calendar addon to the TNG software for online genealogy.
I have a fairly large family and often have trouble keeping track of birthdays, anniversaries, and the like.
Ive also started keeping track of my familys genealogy via a web-based package, so the solution seemed obvious: add the component I needed so the software I was already using.
The result is called tngCalendar. The calendar is a simple monthly view with birthdays, wedding anniversaries, and dates of death overlaid.
tngCalendar operates in conjunction with the TNG package, but can (and should) be installed separately. Simply download the package, and uncompress in a temporary directory. Edit the php file according to the directions contained inside, and copy the pieces into place.
Note that tngCalendar may circumvent your security setup by "giving away" birth and marriage dates relevent to living persons. However, since the exact year of a persons birth or marriage is not shown on the calendar (it only shows anniversaries, the year is only used for dFixed a bug in the anniversaries.php links (the day numbers on the calendar).
Enhancements:
- This release fixes a bug introduced in 1.2 that caused anniversaries to fail to display.
- It fixes a bug that caused links to point to the wrong entries in some cases.
- It adds support for nickname, lnprefix, and suffix when available.

pwho is a parallel whois tool for programs.
Programs that need to do whois lookups to test availablity (because names can be registered that have no NS records) can interface with pwho.
The input is simple:
name[ whoisserver]
Where "name" is a query without spaces for "whoisserver", which MUST be an IPv4 address. input is line-separated.
The output is simple:
q 0 st
Where "q" is the input-line number in sequence-space, and "st" is one of:
permfail - name is not registered
remotefail - temporary error; (try again later?)
ok - name IS registere
Enhancements:
- pwho.c: poll now waits- this causes kernel blocks but at least keeps load down

GMP compiler tool simplifies the use of GMP, the GNU multiple precision library. It scans a C source file for specially marked GMPS arithmetic expressions and replaces them with plain C.
The abbreviation gmpc stands for GMP compiler, or alternatively GMPS-to-C compiler. GMPS arithmetic expressions are straightforward infix expressions which transparently support the special types mpq_t, mpz_t and mpf_t as defined by GMP. GMPS means, rather unimaginatively, `GMP script.
No dependencies are added to the resulting C source, so there is no need to include additional header files or link with special libraries other than GMP.
Invoking gmpc
To translate a .gmpc file to C source, at least the input and output files must be given. The most concise invocation would look like this:
gmpc -o foo.c foo.gmpc
This will translate foo.gmpc into foo.c.
It is highly recommended to enable all warnings with the -Wall switch:
gmpc -Wall -o foo.gmpc foo.c
Other switches can be used to change the default behaviour of gmpc. They are listed in the following sections.
Enhancements:
- Added support for C-like compound assignments, increment and decrement operators.
- Fixed an assignment precedence bug.
- Temporary variables and constants are grouped together to make generated code more readable.
- Added Doxygen comments and configuration file.

EasyPG is yet another GnuPG interface for Emacs. EasyPG package consists of two parts:
- The EasyPG Assistant - A GUI frontend of GnuPG
- The EasyPG Library - A library to interact with GnuPG
Main features:
The EasyPG Assistant provides the following features:
- Cryptographic operations are usable from dired mode.
- Keyring management interface.
- Transparent encryption/decryption of *.gpg files.
The EasyPG Library provides the following features:
- The API covers most functions of GnuPG.
- Designed to avoid potential security pitfalls around Emacs.
Passphrase may leak to a temporary file
The function call-process-region writes data in region to a temporary file. If your PGP library used this function, your passphrases would leak to the filesystem.
The EasyPG Library does not use call-process-region to communicate with a gpg subprocess.
Passphrase may be stolen from a core file
If Emacs crashes and dumps core, Lisp strings in memory are also dumped within the core file. read-passwd function clears passphrase strings by (fillarray string 0) to avoid this risk. However, Emacs performs compaction in gc_sweep phase. If GC happens before fillarray, passphrase strings may be moved elsewhere in memory. Therefore, passphrase caching in elisp is generally a bad idea.
The EasyPG Library dares to disable passphrase caching. Fortunately, there is more secure way to cache passphrases - use gpg-agent.
