Solaris 10 End of Life
Solaris 10 end of life Continue Oracle Solaris 10 has had an amazing OS update, including ground features such as zones (Solaris containers), FSS, Services, Dynamic Tracking (against live production operating systems without impact), and logical domains. These features have been imitated in the market (imitation is the best form of flattery!) like all good things, they have to come to an end. Sun Microsystems was acquired by Oracle and eventually, the largest OS known to the industry, needs to be updated. Oracle has set a retirement date of January 2021. Oracle indicated that Solaris 10 systems would need to raise support costs. Oracle has never provided migratory tools to facilitate migration from Solaris 10 to Solaris 11, so migration to Solaris has been slow. In September 2019, Oracle decided that extended support for Solaris 10 without an additional financial penalty would be delayed until 2024! Well its March 1 is just a reminder that Oracle Solaris 10 is getting the end of life regarding support if you accept extended support from Oracle. Combined with the fact gdpR should take effect on May 25, 2018 you want to make sure that you are either upgraded to Solaris 11.3 or have taken extended support to obtain any patches for security issues.

Support for Mobile Augmented and Synthesized Worlds
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Illinois Digital Environment for Access to Learning and Scholarship Repository Support for Mobile Augmented and Synthesized Worlds December 17, 2007 Won J. Jeon and Roy H. Campbell {wonjeon, rhc}@uiuc.edu Department of Computer Science University of Illinois at Urbana-Champaign Abstract Virtual worlds provide 3D-immersive experiences to users and some of them already have already launched commercial service to users. As computing environment becomes more heterogeneous, more mobile users are anticipated to access the virtual world with their mobile devices. However, still there are challenges and problems to be addressed for mobile users. In this report, state-of-art virtual world platforms are presented and their key features are compared. We compare possible approaches to tackle these problems to support virtual worlds for mobile devices. Transcoding scheme at the proxy is presented and evaluated for a given computing and networking environment. 1. Introduction A virtual world is a computer-simulated or synthesized environment where multiple users inhabit and interact to each other via avatars. The world mimics the real world via simulated real world physics and the persistence of the world comes from maintaining and updating the state of the world around the clock. Historically this concept is rooted from distributed interactive simulation (DIS) and massively multiplayer online role- playing game (MMORPG). DIS is used mainly by military organizations whereas MMORPG has gained huge popularity among general users or gamers. The world is typically represented as 2D or 3D graphics to multiple users. -

After all, developers are a demanding audience. But the article received hundreds of comments on Reddit, Slashdot, Hacker News, and Twitter, and it inspired many letters to the editor. The piece even received happy social media posts from those who made the list, including the US National Security Agency and a.i. solutions. The US National Security Agency was secretly pleased we noticed its Ghidra binary decompilation tool. The team from a.i. solutions was happy its DSTE trajectory design tool made the list. The tenor of conversation was both positive and polite. That speaks volumes about the excellent character of Java developers, don’t you think? But, developers being who they are, opinions on what should have made the list abounded. The good news is, Java has transformed the world. The bad news is, my list didn’t represent enough of the world beyond the United States. For example, there’s the Java code written to manage the Brazilian Healthcare Information System and the Brazilian tax system (Duke’s Choice Award winner in 2005). -
Dream Center for Lunar Science: a Three Year Summary Report

Abstract. In early 2009, the Dynamic Response of the Environment At the Moon (DREAM) lunar sci- ence center became a supporting team of NASA's Lu- nar Science Institute specifically to study the solar- lunar connection and understand the response of the lunar plasma, exosphere, dust, and near-surface envi- ronments to solar variations. DREAM especially em- phasizes the effect extreme events like solar storms and impacts have on the plasma-surface-gas dynamical system. One of the center's hallmark contribution is the solar storm/lunar atmosphere modeling (SSLAM) study that cross-integrated a large number of the cen- The Solar-Lunar Connection studies by DREAM.

A number of other key studies were performed, including a unique ground-based observation of the LCROSS impact-generated sodium plume, exo- atmosphere modeling studies, and focused studies on the formation and distribution of lunar water. The team is supporting ARTEMIS lunar plasma interaction stud- ies via modeling/data validation efforts, especially ex- amining ion reflection from magnetic anomalies and pick-up ions from the Moon. -

Specifically, which of these are active and capable display walls, video projectors, a haptic input device (e.g., a of helping us to engineer a collaborative, virtual environment “wand” to provide touch capabilities), and multidimensional (CVE)? A review of the literature and numerous project websites indicates an array of both overlapping and disparate approaches sound. The computing platforms to drive these systems also to this problem. In this paper, we review and perform a risk differ: desktop-VR requires a workstation-class computer, assessment of 16 prominent desktop-VR technologies (some mainstream OS, and VR libraries, while a CAVE often runs on building-blocks, some entire platforms) in an effort to determine a multi-node cluster of servers with specialized VR libraries the most efficacious tool or tools for constructing a CVE. and drivers.

However, with the advent of the Constellation Program, NASA plans a triumphant manned return to the moon, and the establishment of a permanent lunar base near the south pole. One goal of the base is to further exploration and research of the lunar surface. With the installation of a permanent outpost, a transportation infrastructure must be developed in order to efficiently travel, research, and explore the Moon’s surface. Since a permanent outpost has never been developed, one can use the Antarctic base infrastructure as an analogue to what means of transportation must be made available in such an uninhabitable, unexplored environment. For example, in Antarctica, scientists have the means to travel short distances between buildings and around the base using snowmobiles, and the ability to conduct longer research missions using closed cabin vehicles. The use of helicopters and aircraft enables unsurpassed range and speed for long distance missions.
