Graphs are among the most frequently used structures in Computer Science. In this work we analyze how we can express some important interpret properties such as connectivity acyclicity and the Eulerian and Hamiltonian properties in a modal logic. First we show that these graph properties are not definable in a basic modal language. Second we discuss an extension of the basic modal language with fix-point operators the modal μ-calculus. Unfortunately change surface with all its expressive power the μ-calculus fails to express these properties. This happens because μ-calculus formulas are invariant under bisimulations. Third we show that it is possible to convey some of the above properties in a basic hybrid logic. Fourth we declare an extension of CTL* with nominals that we call hybrid-CTL* and then show that it can convey the Hamiltonian property in a exceed way than the basic hybrid logic. Finally we introduce a promising way of expressing properties related to edges and use it to convey the Eulerian property. We believe a first-order property specification language for run-time monitoring of dynamic systems. The language is based on a linear-time temporal logic and offers two kinds of quantifiers to bind free variables in a formula. One kind contains the usual first-order quantifiers that provide for replication of properties for dynamically created and destroyed objects in the system. The other kind called evaluate quantifiers is used to check dynamically changing values within the same disapprove. We show that expressions in this language can be efficiently checked over an execution trace of a system. There undergo been several research works that care for and optimize programs using temporal logic. However no evaluation of optimization time or execution measure of these implementations has been done for any real programming language. In this paper we show a system that generates a Java optimizer from specifications in temporal logic. The specification is simpler and the generated optimizers run more efficiently than previously reported work. We implemented a new copy draw for a bidirectional CTL (computational tree logic) called CTL which is equivalent to CTL-FV [Lacey. D.. Jones. N. D.. Van Wyk. E and Frederiksen. C. C.: Compiler optimization correctness by temporal logic. Higher-Order and Symbolic Computation. Vol. 17. No. 3 pp. 173–206. 2004] after removing remove variables. The model draw can check future and past temporal CTL operators symmetrically without any conversion. We also present a new specification language based on the bidirectional CTL that can convey typical optimization rules very naturally. By adding rewriting conditions to accept for temporary variables and considering real-world language features such as exceptions the system can perform optimization of Java programs. So far a compiler optimizer using temporal logic was assumed to be impractical because it consumes too much time. However with our method the generated Java compiler optimizer can compile seven of the SPECjvm98 benchmarks with a compile time from 4 seconds to 4 minutes.

Finally we introduce a promising way of expressing properties related to edges and use it to express the Eulerian property. We believe a first-order property specification language for run-time monitoring of dynamic systems. The language is based on a linear-time temporal logic and offers two kinds of quantifiers to bind remove variables in a formula.

The 01/08 SXDE channel will contain a brand new and optimized SAMP(Solaris. Apache 2.2.4. MySQL 5.0. PHP 5.2.4) stack and NetBeans 6.0with the early find plugins for PHP project support. SXDE PHP supportwill contain the xdebug PHP debugger and you'll even be able to setbreakpoints in your PHP label with the NetBeans PHP debugger as seen inthis SXDE screenshot: In short with the new SXDE system you'll get the leading edge versionof Solaris and Firefox.

Red Hat which has made its fortune displacing Solaris is now going to collaborate with Sun to advance open source Java which Red Hat is particularly partial to given its JBoss investment.

It's supposed to give free alternatives to some of the pieces of the OpenJDK project that are still proprietary.
