Ericson 25. The Ericson 25, also called the Ericson 25 Mark I is an American trailerable sailboat that was designed by Bruce King as a cruiser and first built in 1973.

The design was replaced in the company product line in 1978 by the Ericson 25+, also called the Ericson 25 Mark II.

Production
The design was built by Ericson Yachts in the United States, from 1973 until 1978, but it is now out of production.

Design
The Ericson 25 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, an angled transom, a transom-hung rudder controlled by a tiller and a fixed fin keel or an optional keel and centerboard combination.

A tall rig was also available, with a mast about  taller, intended for areas with lighter winds.

The boat is normally fitted with a small inboard engine or a  outboard motor for docking and maneuvering. The fuel tank holds .

The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two straight settee quarter berths in the main cabin, around a drop-leaf table. The galley is located on both sides of the companionway ladder. The galley is equipped with a two-burner stove, an icebox and a sink. The head is located just aft of the bow cabin on the starboard side. Cabin headroom is  and the fresh water tank has a capacity of . There is an anchor locker in the bow.

For downwind sailing the design may be equipped with a spinnaker.

The design has a PHRF racing average handicap of 234 and a hull speed of .

Variants
Ericson 25 fin keel
This model displaces  and carries  of lead ballast. The boat has a draft of  with the standard keel.
Ericson 25 keel and centerboard
This model displaces  and carries  of ballast. The boat has a draft of  with the centerboard down and  with it retracted.

Operational history
In a 2010 review Steve Henkel wrote, "when she came out in 1972, this vessel was seen as remarkably roomy for a 25-footer, as indeed she was ... The Ericson 25 Mk I ... is well-finished and nicely laid out for comfortable alongshore cruising, She is also designed to race, with testing done in the Davidson Laboratory at Stevens Institute and a hull rated as a quarter-tonner. Best features: She cleverly combines a high aspect ratio centerboard with a trunk almost totally beneath the cabin sole, eliminating the nuisance of a protruding trunk splitting the cabin in two. Her sales brochure touts her easy trailerability, and shows a photo of the boat on a four-wheel trailer, her 7,700 pounds of load towed by a Cadillac sedan—something that today no ordinary car, including a Cadillac, could come close to doing. Worst features: We could not come up with any significant negative features."

Authentication and authorization infrastructure. Authentication and authorization infrastructure (AAI) refers to a service and a procedure that enables members of different institutions to access protected information that is distributed on different web servers.

Traditional approaches to authorization and access control in computer systems are not sufficient to address the requirements of federated and distributed systems, where infrastructural support may be required. Authentication and authorization infrastructure solutions address such limitations. With an AAI, access control is not managed by a central register, but by the respective organization of the user who wishes to access a specific resource.

In Switzerland, the SWITCH Information Technology Services Foundation is developing a Shibboleth-based AAI system that helps Swiss universities in particular to make their e-learning offers accessible to students beyond their own institutional boundaries. Based on the success of SWITCHaai, other countries are following with their own AAI projects.

Rio de Janeiro Petrochemical Complex. The Rio de Janeiro Petrochemical Complex, (; abbreviated as COMPERJ), is a petrochemical facility in Itaboraí, Rio de Janeiro, Brazil built by Petrobras on a 45 km2 piece of land making it the largest single enterprise by Petrobras and one of the largest industrial facilities in the world. It was heavily involved in Operation Car Wash, a large and widespread criminal investigation by Brazilian police, to which its license of operation was revoked leading to high numbers of unemployment and debt.

Operation 
The facility contains a refining unit with a processing capacity of 165,000 barrels of oil per day. Initially, it was planned to use heavy oil from the Marlim oil field located in Campos Basin, a few kilometers north of Rio de Janeiro. In addition to the refining unit, a first-generation basic petrochemicals unit (ethylene, benzene, p-xylene and propylene) and six second-generation petrochemicals units were planned to be built. The main thermoplastic resins to be produced by the second generation petrochemical units will be polypropylene (850 thousand tons/year), polyethylene (800 thousand tons/year) and polyethylene terephthalate.(600 thousand tons/year).

In addition to the production units, a large utility center will be built, responsible for supplying water, steam and electrical energy necessary for the operation of the complex.

Stealth (1984 video game). Stealth is a pseudo-3D rail shooter designed by Tracy Lagrone and Richard Sansom. The game was published in 1984 by Broderbund for the Atari 8-bit computers and Commodore 64.

Gameplay

The player's mission in Stealth is to pilot a low-level bomber-fighter ship to infiltrate enemy territory and travel a distance of 10,000 miles to reach and destroy the Black Tower (enemy citadel). The ship uses pulse energy for power, so the player must keep an eye on the fuel supply in addition to avoiding obstacles and shooting enemies. Energy fields are randomly scattered around the planet. The yellow ones contain fields of positive energy that can be used to refuel the player's ship. On the other hand, there are also red, negative energy fields that will drain the ship of energy. On the way to the Black Tower, the player has to watch out for enemy bunkers, tanks, rockets, reconnaissance planes and fighters. Additionally, the player must destroy the radar towers, because a failed attempt to destroy them automatically triggers the launch of a homing missile.

The game has five levels, and each successive level is much more difficult.

Development
An early version of the game was called Landscape. Stealth uses excerpts of Johann Sebastian Bach's Harpsichord Concerto in D minor as its title music.

Reception
The game has been met with positive-to-mixed reviews. Writing for Commodore Power/Play, Tom Benford praised the game: "Stealth is software par excellence. Everything, and I mean everything, about the game is positively top-notch: sound, color, graphics, breathtaking animation, play action, challenge level, continued interest—I'd really have to give it a "10" in all of these categories." Antics Jack Powell called the game "a welcome fix for the shoot-'em'down arcade freaks who have been wondering where the next serious laser-zap would come from," praising its graphics for "creat[ing] an excellent sense of place and dimension." Gregg Keizer of Compute!'s Gazette called it graphically "outstanding," stating: "It has one of the best 3-D views we've seen." They furthermore described the gameplay as "addicting", stating that "it's hard to tear yourself away from the screen" and calling it "one of the best [shoot-'em-up-arcade games] around."

Steve Panak was less positive in his review for ANALOG Computing and stated: "It is a shame that a game with such nice graphics denies you equally fine playability. Stealth is fascinating the first time around, but you'll tire of it quickly." Likewise, Zzap!64 gave the game an overall score of 56%, largely praising the graphics but criticizing the sound and lastability.
