Ollie's Follies. Ollie's Follies is a platform game designed by Frank Cohen and published in 1984 by Americana for Atari 8-bit computers and Commodore 64.

Gameplay

The object of the game is to guide the titular "Ollie" through a series of increasingly difficult levels. In each room, the player must make his way through a series of platforms and ramps to an exit that leads to another screen. Some platforms are patrolled by robots, and if Ollie touches one of them, he loses his life. There are energizers scattered throughout the room, which give Ollie the power to touch and destroy robots with impunity.

The screens become increasingly difficult with additional hazards and features. There are large fans that cause Ollie to get blown off ramps, sliding ledges, trampolines, teleports and laser walls. There are a total of 24 rooms. The player wins by getting Ollie through all of them.

Reception
Ollie's Follies was met with fairly good reviews. Zzap!64 reviewers were "pleasantly surprised to find that Ollie’s Follies isn't all that bad", and rated it "Oldie, but goodie platform game". Electronic Games reviewer noted that "Ollie's Follies is a very good game", but he also expressed doubts about how the game would fare in the crowded platform game market.  Bob Chappell writing for Atari User concluded: "Ollie's Follies is very enjoyable and likely to keep you coming back for more until you've cracked it. At the low price it's too good a bargain to miss."

Empowerment (artificial intelligence). Empowerment in the field of artificial intelligence  formalises and quantifies (via information theory) the potential an agent perceives that it has to influence its environment. An agent which follows an empowerment maximising policy, acts to maximise future options (typically up to some limited horizon). Empowerment can be used as a (pseudo) utility function that depends only on information gathered from the local environment to guide action, rather than seeking an externally imposed goal, thus is a form of intrinsic motivation. 

The empowerment formalism depends on a probabilistic model commonly used in artificial intelligence. An autonomous agent operates in the world by taking in sensory information and acting to change its state, or that of the environment, in a cycle of perceiving and acting known as the perception-action loop. Agent state and actions are modelled by random variables () and time (). The choice of action depends on the current state, and the future state depends on the choice of action, thus the perception-action loop unrolled in time forms a causal bayesian network.

Definition 
Empowerment () is defined as the channel capacity () of the actuation channel of the agent, and is formalised as the maximal possible information flow between the actions of the agent and the effect of those actions some time later. Empowerment can be thought of as the future potential of the agent to affect its environment, as measured by its sensors.

In a discrete time model, Empowerment can be computed for a given number of cycles into the future, which is referred to in the literature as 'n-step' empowerment. 

The unit of empowerment depends on the logarithm base. Base 2 is commonly used in which case the unit is bits.

Contextual Empowerment
In general the choice of action (action distribution) that maximises empowerment varies from state to state. Knowing the empowerment of an agent in a specific state is useful, for example to construct an empowerment maximising policy. State-specific empowerment can be found using the more general formalism for 'contextual empowerment'.  is a random variable describing the context (e.g. state).

Application 
Empowerment maximisation can be used as a pseudo-utility function to enable agents to exhibit intelligent behaviour without requiring the definition of external goals, for example balancing a pole in a cart-pole balancing scenario where no indication of the task is provided to the agent. 
Empowerment has been applied in studies of collective behaviour and in continuous domains. As is the case with Bayesian methods in general, computation of empowerment becomes computationally expensive as the number of actions and time horizon extends, but approaches to improve efficiency have led to usage in real-time control. Empowerment has been used for intrinsically motivated reinforcement learning agents playing video games, and in the control of underwater vehicles.

Henschel P.87. The Henschel P.87 was a proposed single-engine Schnellbomber design put forth by German aircraft manufacturer Henschel for the Luftwaffe during WWII. It was to utilize the then seldom-used tail-first canard arrangement, swept wings, and two vertical fins mounted on the wingtips.

Design 
In general design, the P.87 was a single-engine, tail-first monoplane design. The unusual arrangement allowed for the crew to all be placed in the nose of the aircraft, ahead of the powerplant & propeller, which would have been quite novel for a propeller-driven aircraft of the time. The P.87 was to be powered by a single rear-mounted Daimler Benz DB 610 engine (the same type used on the Heinkel He 177 heavy bomber) in pusher configuration, driving a single or contra-rotating propeller. It featured an unconventional tail-first canard layout, with the tailplane being located towards the nose of the aircraft and the primary wings being at the rear of the fuselage, along with the vertical fins at said wings' tips. The mainplanes were swept at 30°. The landing gear was of tricycle configuration, with a nosewheel positioned directly below the crew and rear wheels retracting into the wing roots. Offensive armament would have most likely consisted of multiple 30mm MK 108 autocannon in the nose, with bombs either being carried directly underneath the fuselage and wings, and/or in an internal bomb bay.

Cancellation 
The P.87 was theoretically a sound design, but a combination of a lack of experience among German pilots in flying pusher-configuration aircraft, and the unconventional and relatively untested layout, lead to the whole project being dropped to focus on higher priorities. No mock-up or prototype was ever constructed, and no RLM number was designated, with only paper design work ever being done.

Pick glass. A pick glass also known as a piece glass is a magnifying glass helpful in counting thread count. It is used to determine the number of yarns in warp and weft in woven fabrics and courses and wales in knitted fabrics. Compact constructions of fabrics may have a higher thread count. That is also called "cloth count".

Function 
Pick glass aid in measuring the following.

Ends and picks 
Ends per inch is the number of warp threads per inch of woven fabric.

Picks per inch is the number of weft threads per inch of woven fabric. Pick is a term that refers to a single weft thread. By and large, the more ends and picks per inch, the finer the cloth. Balanced plain weave fabrics have warp and weft threads that are the same weight (size) and have the same number of ends and picks per inch.

Courses and Wales 
Loops are the building blocks of knitted fabrics, and courses and wales in knitted fabrics are importantly similar to ends and pick in woven fabrics. The knitting structure is formed by intermeshing the loops in consecutive rows.

 Courses: are the total number of horizontal rows measured in per inch or per centimetre. The course is a horizontal row of loops formed by all the adjacent needles during one revolution. course length is obtained by multiplying loop length with the number of needles involved in the production of the course.
 Wales: are the number of vertical columns measured in per inch or per centimetre.

Nano-Babies. Nano Babies is a science fiction essay film by Swiss director Thomas Imbach, which he realised in 1998 together with Jürg Hassler. Nano Babies follows everyday life in a crèche at a technical university. Two future-creating worlds - the worlds of the children and their parents - collide. Nano Babies was produced for Swiss television.

Plot 
In the 50-minute film, small children are shown in a day nursery: As in Thomas Imbach's previous film Ghetto, fragments of the children's everyday lives, captured in rich detail, alternate with a variety of (cold, forbidding) exterior views and artful sounds (the day nursery is part of a university and the building also houses the laboratories and offices of the parents, mostly high-tech scientists).

Background 
Imbach and his cinematographer Jürg Hassler call their film, shot in Cinemascope, a "science fiction essay", which, in a thoroughly ironic way, pretty much sums up the cinematic argument of Nano Babies.

Eastward Ho 24. The Eastward Ho 24 is an American trailerable sailboat that was designed by Walter McInnis of Eldridge-McInnis, as a cruiser and first built in 1975.

Production
The design was built by C. E. Ryder in Bristol, Rhode Island under contract, then finished and marketed by Portsmouth Yachts in the United States. The first boats were built in 1975, but it is now out of production.

Design
The Eastward Ho 24 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a spooned plumb stem, an angled transom, a keel-mounted rudder controlled by a tiller and a fixed long keel. With the optional bowsprit it can be cutter rigged. The boat displaces  and carries  of lead ballast.

The boat has a draft of  with the standard keel.

The boat is fitted with a Swedish Volvo MD4 diesel engine of , a Universal Atomic 4  or Palmer gasoline engine for docking and maneuvering. The fuel tank holds  and the fresh water tank also has a capacity of .

The design has sleeping accommodation for four people, with two straight settee quarter berths in the main cabin and upper berths above them. The main cabin has a drop-leaf table. The galley is located on both sides of the companionway ladder. The galley is equipped with a stove, an icebox and a sink. The head is in the bow. Cabin headroom is .

The design has a PHRF racing average handicap of 269 and a hull speed of .

Operational history
In a 2010 review Steve Henkel wrote, "the Eastward Ho was available either as a sloop ... or, with a bowsprit added, as a cutter. There was also a choice of motive power, including a Volvo MD-2 diesel (22 hp) or an Atomic Four (30 hp). The designer, Eldredge McInnis of Boston, MA, a firm started in 1926, tended to specialize in large yachts, especially motorsailers. (The firm closed in 1976 when Walter J. McInnis retired at age 83. Albert Eldredge had died in 1936 but was involved in sales, not design.) Even though she's less than 24 feet on deck, because of her displacement of 7,000 pounds she can use the power to punch through waves. Typically, these boats were offered with a yacht finish, teak and holly sole, teak interior, fine jointer-work, and so on. Best features: This is a top-of-the-line yacht for her size range. She is durable, beautiful to look at, and a good sailer, especially when it breezes up. Worst features: When these boats come onto the market, which is rare, they typically command a premium price."

A. T. Stewart (pilot boat). The A. T. Stewart was a 19th-century Sandy Hook pilot boat built in 1865 at the Edward F. Williams shipyard to replace the pilot boat George Steers, which was lost in 1865. She was built for the New Jersey and New York Sandy Hook Pilots Association. The Stewart was in a collision with the steamship Scotia and sank in 1869. She was replaced by the James Gordon Bennett in 1870.

Construction and service 

The pilot-boat A. T. Stewart No. 6, was launched from the shipyard of Edward F. Williams, at Greenpoint, Brooklyn, on October 11, 1865. She was the twelfth vessel of her class built by Williams in the last ten years. There was a large party in attendance. She was built for pilots of the New Jersey and Sandy Hook Pilots' Association. She was built to replace the George Steers, No. 6, which was lost in February 1865. At the launch and naming ceremony, Ellen M. Clark, daughter of Jonah N. Clark, did the christening by breaking a bottle of champagne over the bow. The name of the boat was nominated by the friends of Alexander Turney Stewart, the dry goods millionaire businessman. The ship master was Captain Daniel C. Chapman.

The A. T. Stewart, was registered as a pilot Schooner with the Record of American and Foreign Shipping, from 1871 to 1874. Her owners were the Pilots' Association; built-in 1865 at Greenpoint, New York; and her hailing port was the Port of New York. Her dimensions were 80 ft. in length; 21 ft. breadth of beam; 7.10 ft. depth of hold; and 90-tons Tonnage.

On May 22, 1866, the pilot boat A. T. Stewart, was in a collision with the Delaware schooner Transit, twenty miles east of Cape May Lightship. The Stewart was towed into port and reported damages in the sum of $5,000. On April 9, 1869, a collision case for the A. T. Stewart was brought before the United States District Court. The case was Chapman vs. the Schooner Transit. The court ruled that both boats were equally responsible for the collision and should share the cost for damages. The court also made the decision to remove the wreck of the A. T. Stewart, from the channel outside Sandy Hook.

End of service

On November 30, 1869, the A. T. Stewart sank when she came in collision with the steamship Scotia off Sandy Hook, New Jersey. The pilots and crew were saved and brought to port. When the A. T. Stewart was lost in 1869, the James Gordon Bennett, No. 6 was built in 1870 to replace her.
