    KaNaPi

    KaNaPi

    Educational Linux Distribution

    Main goals: * Prepare operating system based on Linux kernel and free software for use at home from scratch by building sources. Binary packages/images are also available. * Each package is installed in separate directory, so you can use different versions of applications and libraries by design. * There is only one user 'kanapi' with root permissions, so you don't have to login, remember passwords, etc. * Simple configuration * Automatic compilation.

    QSquidClassRoom

    QSquidClassRoom

    QSquidClassRoom is a GUI for a specific squid3 configuration

    QSquidClassRoom was designed to make teacher's control over student Internet access fast and simple. A couple of mouse clicks allows you to control black and white access lists, ports, host allowed to access Internet. You can easily connect or disconnect any user or even block any media downloads. QSquidClassRoom may be a simple user without root rights. Recomended squid3 configuration file is included in the distribution. Also detailed description (in russian) included in documentation. For advanced uses it should be said that QSquidClassRoom is a complex of squid3 configuration file and access control lists, GUI tool and a program to reconfigure squid3 using user id substitution. Using this complex you can manage up to 7 access control lists in easy way. Note, that for use QSquidClassRoom v1.1 you need a libvcr library of mine, which you can get at https://sourceforge.net/projects/libvcr

    Bat2015

    Bat2015

    Bachelor of Science (Informatik)

    The toolkit glpk supports methods for mixed integer linear programming (MILP). These methods solve Capital Budgeting Problems (CBP). Unfortunately, glpk does not support any multithreading and there is no feature to distribute problems via network connections. Today, this is a pitiable sight, because modern computer systems are coupled by networks and support multi threading. We create a distributed system with Apache thrift and the C-API of glpk. Now, it is possible to use as many cores in a network as you want. With a focus on the MILP methods we implement a load balancing and speed up the solving process in a multiplicative way. Sometimes we have super-linear speedup with a small set of hardware. With a splitting of problems, parallel computing and distributing the actual best solution to all running processes we solve CBP much faster than a sequential processing can do.
