European Conference on Object-Oriented Programming. The European Conference on Object-Oriented Programming (ECOOP) is an annual conference covering topics on object-oriented programming systems, languages and applications. Like other conferences, ECOOP offers various tracks and many simultaneous sessions, and thus has different meaning to different people.

The first ECOOP was held in Paris, France in 1987. It operates under the auspices of the Association Internationale pour les Technologies Objets, a non-profit organization located in Germany.

ECOOP’s venue changes every year, and the categories of its program vary. Historically ECOOP has combined the presentation of academic papers with comparatively practical experience reports, panels, workshops and tutorials.

ECOOP helped object-oriented programming develop in Europe into what is now mainstream programming, and helped incubate a number of related disciplines, including design patterns, refactoring, aspect-oriented programming,  and agile software development.

The winners of the annual AITO Dahl-Nygaard Prize are offered the opportunity to give a keynote presentation at ECOOP.

The sister conference of ECOOP in North America is OOPSLA.

Windows Filtering Platform. Windows Filtering Platform (WFP) is a set of system services in Windows Vista and later that allows Windows software to process and filter network traffic.  Microsoft intended WFP for use by firewalls, antimalware software, and parental controls apps. Additionally, WFP is used to implement NAT and to store IPSec policy configuration.

WFP relies on Windows Vista's Next Generation TCP/IP stack.  It provides features such as integrated communication and per-application processing logic. Since Windows 8 and Windows Server 2012, WFP allows filtering at the second layer of TCP/IP suite.

Components 
The filtering platform includes the following components:

 Shims, which expose the internal structure of a packet as properties. Different shims exist for protocols at different layers. WFP comes with a set of shims; users can register shims for other protocols using the API. The in-built set of shims includes:
 Application Layer Enforcement (ALE) shim
 Transport Layer Module (TLM) shim
 Network Layer Module (NLM) shim
 RPC Runtime shim
 Internet Control Message Protocol (ICMP) shim
 Stream shim

 Filtering engine, which spans both kernel-mode and user-mode, providing basic filtering capabilities. It matches the data within a packetas exposed by the shimsagainst filtering rules, and either blocks or permits the packet. A callout (see below) may implement any other action as required. The filters operate on a per-application basis. To mitigate conflicts between filters, they are given weights (priorities) and grouped into sublayers, which also have weights. Filters and callouts may be associated to providers which may be given a name and description and are essentially associated to a particular application or service.
 Base filtering engine, the module that manages the filtering engine. It accepts filtering rules and enforces the security model of the application. It also maintains statistics for the WFP and logs its state.
 Callout, a callback function exposed by a filtering driver. The filtering drivers provide filtering capabilities other than the default block/allow. Administrators specify a callout function during registration of a filter rule. When the filter matches, the system invokes the callout, which handles a specified action.

Diagnostics
Starting with Windows 7, the netsh command can diagnose of the internal state of WFP.

Hotfix
Microsoft released three out-of-band hotfixes for WFP in Windows Vista and Windows 7 to address issues that could cause a memory leak, loss of connectivity during a Remote Desktop Connection session, or a blue screen of death. Later, these hotfixes were rolled up into one package.

Schoepite. Schoepite, empirical formula  (UO2)8O2(OH)12·12(H2O) is a rare alteration product of uraninite in hydrothermal uranium deposits. It may also form directly from ianthinite. The mineral presents as a transparent to translucent yellow, lemon yellow, brownish yellow, or amber orthorhombic tabular crystals. Although over 20 other crystal forms have been noted; rarely in microcrystalline aggregates. When exposed to air schoepite converts over a short time to the metaschoepite form (UO3·H2O, ) within a few months of being exposed to ambient air.

The hardness is 2.5, density is 4.8 g/cm3, and it streaks yellow. 

It was first described from specimens from Shinkolobwe mine in Belgian Congo in 1923, several additional localities are known.

Schoepite was named to honor Alfred Schoep (1881–1966), Professor of Mineralogy at the University of Ghent, Belgium.

Japanese destroyer Hanazuki. was an  destroyer of the Imperial Japanese Navy. Her name translates as "flower (sakura) moon", or an alternate name for "March".

Design and description
The Akizuki-class ships were originally designed as anti-aircraft escorts for carrier battle groups, but were modified with torpedo tubes and depth charges to meet the need for more general-purpose destroyers. The ships measured  overall, with beams of  and drafts of . They displaced  at standard load and  at deep load. Their crews numbered 300 officers and enlisted men.

Each ship had two Kampon geared steam turbines, each driving one propeller shaft using steam provided by three Kampon water-tube boilers. The turbines were rated at a total of  for a designed speed of . The ships carried enough fuel oil to give them ranges of  at speeds of .

The main armament of the Akizuki class consisted of eight 10 cm Type 98 dual-purpose guns in four twin-gun turrets, one superfiring pair fore and aft of the superstructure. Hanazuki was equipped with 41 Type 96  anti-aircraft (AA) guns in seven triple-gun mounts and twenty single mounts. The ships were also each armed with four  torpedo tubes in a single quadruple rotating mount amidships for Type 93 (Long Lance) torpedoes; one reload was carried for each tube. The later batches of ships were each equipped with two depth charge throwers and two sets of rails for which 72 depth charges were carried. Hanazuki was equipped with a Type 13 early-warning radar on her mainmast and a Type 22 surface-search radar on her foremast.

Construction and career

In June 1947, Hanazuki was turned over to United States as "DD-934", and was later sunk as target off Gotō Islands, Japan on 3 February 1948.

Yoizuki was equipped with a Type 13 early-warning radar on her mainmast and a Type 22 surface-search radar on her foremast.

Construction and career
In March, 1946, Yoizuki was used to transport over 1,000 Formosans, Filipinos and Japanese prisoners of war from Sydney, Australia. The conditions aboard ship and the obvious distress of the repatriates prompted controversy in Australia. On 29 August 1947, Yoizuki was turned over to the Republic of China. Renamed CNS Fen Yang, she was scrapped in 1963.

Islands in the Sky: Bold New Ideas for Colonizing Space. Islands in the Sky: Bold New Ideas for Colonizing Space (Stanley Schmidt and Robert Zubrin, eds., Wiley, 1996, ) is a book composed of a collection of factual articles on space colonization, several from recognized experts in the field.

The articles range from colloquial to fairly technical, occasionally deriving results after a series of calculus equations. Their subject matter ranges from colonization of the inner Solar System to the outer Solar System and interstellar colonization, and from novel application of well-understood engineering principles, to speculative physics theories. It includes five articles authored or co-authored by Zubrin; other notable authors include Robert L. Forward, Martyn J. Fogg, and Christopher McKay. The book is also notable for including a publication of Robert Zubrin's Mars Direct mission architecture (first formulated in 1990), which was soon expanded into a book of its own, The Case For Mars: The Plan to Settle the Red Planet and Why We Must, and which provided the impetus for the founding of the Mars Society.

National Robotics Challenge. The National Robotics Challenge is an annual robotics competition in the United States, established in 1986, in which robot contestants compete in one or more of a number of different disciplines.

History
The National Robotics Challenge was originally known as the Society of Manufacturing Engineers Robotic Technology and Engineering Challenge (SME-RTEC). SME-RTEC was established in 1986, making it the first and longest running robotics contest in the United States, by Tom Meravi, Associate Professor from Northern Michigan University and James Hannemann, co-chairman of the event. The first edition of the competition had two work cells and two pick-and-place competitions, and over the next 15 years, Meravi and Hannemann oversaw the growth of the competition to 17 different contests by 2002. Hannemann died in July 2001, after which the SME announced, at the 2003 awards ceremony in Rochester, New York, that it would discontinue its sponsorship of the event.

Following this announcement, three educators from Marion, Ohio: Ed Goodwin, Ritch Ramey, and Tad Douce, took over the organization of the competition. The 2004 event was held at the Veterans Memorial Coliseum in Marion, with over 200 students participating from several states. The 2005 event grew in both participants and sponsors, and concluded with the addition of 2005 judge Brad Pottkotter, a teacher at Ridgedale High School, as a fourth committee member.

The 2006 National Robotics Challenge included 300 students from five middle schools, 27 high schools, and four post-secondary schools from Ohio, Indiana, Virginia, Pennsylvania, Connecticut, South Carolina, Michigan and New York, with over 180 robots competing in 11 different contest categories. In 2008, Mark Robinson of Marion Harding High School was added to the organizing committee.

The three-day event in 2009 included college students participating from Iowa, Arkansas, New York, Indiana, Michigan and Ohio. Ohio Northern University contributed an automated Ice Cream Sundae machine, which made over 1,000 sundaes for those present. That year saw the largest field of entries to date, and the addition of: the Math Machine challenge, which involved middle school and high school teams compete to complete a maze using Ti-83/84 programmable calculators; the Vex Robotics regional contest; and the AgBot contests for elementary and middle school students. The event also included booths and displays from various robotic industry companies, and various other robotics-related attractions.

Lockheed L-301. Lockheed  L-301 (sometimes called the X-24C, though this designation was never officially assigned) was an experimental air-breathing hypersonic aircraft project. It was developed by the NASA and United States Air Force (USAF) organization National Hypersonic Flight Research Facility (NHFRF or NHRF), with Skunk Works as the prime contractor.  In January 1977, the program was "tentatively scheduled to operate two vehicles for eight years and to conduct 100 flights per vehicle."  NASA discontinued work on L-301 and NHRF in September 1977 due to budget constraints and lack of need.

Development
The X-24C-L301 was a scaled-up derivative of the Martin X-24C project that was to have been a hypersonic follow-on to the X-15 and X-24 (specifically the X-24B) programs, to take lessons learned from both and integrate them into an airframe capable of at least reaching Mach 8 and engaging in hypersonic skip-glide maneuvers for long range missions. The vehicle would have used both air breathing ram or scramjet propulsion as well as a rocket engine, carrying both RP-1 and LH2 propellant as well as on-board stores of LOX. The X-24C-L301 languished at the design phase when the X-24C project was shelved in September 1977 due a tight NASA budget.

Design

Propulsion
Originally intended to carry the same XLR-99 engine used by the X-15, the primary engine was changed to the LR-105, which was the sustainer engine used on the Atlas launcher. This rocket engine, burning RP-1 and LOX, was intended to accelerate the X-24C to hypersonic speeds in order to ignite the hydrogen fueled, air breathing ram/scramjet mounted in the belly of the airframe with which it would attain cruise speeds of at least Mach 6 and peak velocities of Mach 8+ at altitudes of  or more. As such, this vehicle was plainly not intended to reach orbit.

Airframe
Design of the aircraft in various wind tunnel models and contractor drawings seems to follow variations of the FDL-5 and FDL-8 lifting body shapes originally developed by the USAF Flight Dynamics Laboratory in the 1950s, which were used in the earlier X-23 and X-24A/B programs. With a radically swept delta wing, and 2, 3, or 4 vertical stabilizers, as well as several body flaps (depending on the model), the vehicle did not lack for control surfaces. The vehicle measured  long,  wingspan, and  height.

Various drawings show a payload bay  long and perhaps  diameter.
