GeoToad is a geocaching query tool to help speed up the boring part of geocaching: choosing the cache and collecting the data. It allows you to generate any kind of complex query you want, and the program will go and poll the Geocaching query, grab the data, and output it to any format you want. The Geocache info can be synced straight to your GPS, iPod, PDA, or cell phone in over 20 different formats.
Unifdef is useful for removing #ifdef'ed lines from a file while otherwise leaving the file alone. You specify which symbols are defined or undefined with -D and -U flags, and unifdef removes the corresponding ifdefs, and the enclosed code if appropriate. It's especially useful for removing those "#ifdef BROKEN" and "#ifdef PRIVATE" clauses from code before you release it. Unifdef acts on #if, #ifdef, #ifndef, #elif, #else, and #endif lines, and it knows only enough about C and C++ to know when one of these is inactive because it is inside a comment or a single or double quote.
fupids (the fuzzy userprofile intrusion detection system) is a user-profile based IDS for the OpenBSD kernel. It modifies certain syscalls in order to detect suspicious behavior. For example, it watches for network devices being set to promiscuous mode, and it watches for the creation of listen() sockets by users. fupids also handles a program profile for your local users, and it can find attackers who overtake existing accounts.
Scala is a modern multi-paradigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages including mixins, algebraic datatypes with pattern matching, genericity, and more. It is well integrated with Java and .NET: the Scala compiler produces standard Java class files or .NET assemblies, and Java/.NET libraries and frameworks can be used without glue code or additional declarations.
