Sauropod neck posture is a subject occasionally debated among scientists, with some favoring postures closer to horizontal whilst others a more upright posture. Research has looked at various avenues of evidence and analysis including: attempting to reconstruct the neutral posture of their necks and estimating range of motion by studying the bones; attempting to reconstruct sauropod metabolism and the energy requirements of sustaining incredibly long necks in various postures; and comparing sauropod neck anatomy to those of living animals.

🔗 Judaism

Tza'ar ba'alei chayim (Hebrew: צער בעלי חיים‎), literally "suffering of living creatures", is a Jewish commandment which bans causing animals unnecessary suffering. This concept is not clearly enunciated in the written Torah, but was accepted by the Talmud as being a biblical mandate. It is linked in the Talmud from the biblical law requiring people to assist in unloading burdens from animals (Exodus 23:5).

Lord Buckethead is a satirical political candidate who has stood in four British general elections since 1987, portrayed by several individuals.

The character, an intergalactic villain similar to the Star Wars character Darth Vader, was created by American filmmaker Todd Durham for his 1984 science fiction film Hyperspace. British video distributor Mike Lee adopted Lord Buckethead to stand in the 1987 UK general election and again in the 1992 general election. The character went unused until comedian Jonathan Harvey stood as Lord Buckethead in the 2017 general election; his televised appearance standing next to prime minister Theresa May went viral, drawing media coverage and an online following.

After the 2017 election, Durham asserted his ownership of the character and displaced Harvey. With Durham's authorisation, Lord Buckethead returned in 2019, now played by David Hughes; he appeared at People’s Vote rallies calling for a second Brexit referendum, and stood in the 2019 general election representing the Monster Raving Loony Party. Harvey also stood, using a new character, Count Binface.

The Communications Over Various Feeds Electronically for Engagement Act (COVFEFE Act) is a bill introduced into the United States House of Representatives in 2017 (on June 12), during the 115th United States Congress.

The bill would amend the Presidential Records Act to preserve Twitter posts and other social media interactions of the President of the United States, and to require the National Archives to store such items.

U.S. Representative Mike Quigley, Democrat of Illinois, introduced the legislation in the wake of Donald Trump's routine use of Twitter, stating "In order to maintain public trust in government, elected officials must answer for what they do and say; this includes 140-character tweets. If the president is going to take to social media to make sudden public policy proclamations, we must ensure that these statements are documented and preserved for future reference." If enacted, the bill "would bar the prolifically tweeting president from deleting his posts, as he has sometimes done."

If the bill were enacted, it would see US law treat US presidents' personal social media accounts (such as Trump's "@realDonaldTrump" Twitter account) the same as "official" social media accounts (such as the "@POTUS" Twitter account).

The Volfefe Index is a stock market index of volatility in market sentiment for US Treasury bonds caused by tweets by President Donald Trump.

Bloomberg News observed Volfefe was created due to the statistical significance of Trump tweets on bond prices. ABC News Online posited Volfefe could help analyze interest rate risk in the face of "unpredictable" activity on social media by Trump.

A plasma antenna is a type of radio antenna currently in development in which plasma is used instead of the metal elements of a traditional antenna. A plasma antenna can be used for both transmission and reception. Although plasma antennas have only become practical in recent years, the idea is not new; a patent for an antenna using the concept was granted to J. Hettinger in 1919.

Early practical examples of the technology used discharge tubes to contain the plasma and are referred to as ionized gas plasma antennas. Ionized gas plasma antennas can be turned on and off and are good for stealth and resistance to electronic warfare and cyber attacks. Ionized gas plasma antennas can be nested such that the higher frequency plasma antennas are placed inside lower frequency plasma antennas. Higher frequency ionized gas plasma antenna arrays can transmit and receive through lower frequency ionized gas plasma antenna arrays. This means that the ionized gas plasma antennas can be co-located and ionized gas plasma antenna arrays can be stacked. Ionized gas plasma antennas can eliminate or reduce co-site interference. Smart ionized gas plasma antennas use plasma physics to shape and steer the antenna beams without the need of phased arrays. Satellite signals can be steered or focused in the reflective or refractive modes using banks of plasma tubes making unique ionized gas satellite plasma antennas. The thermal noise of ionized gas plasma antennas is less than in the corresponding metal antennas at the higher frequencies. Solid state plasma antennas (also known as plasma silicon antennas) with steerable directional functionality that can be manufactured using standard silicon chip fabrication techniques are now also in development. Plasma silicon antennas are candidates for use in WiGig (the planned enhancement to Wi-Fi), and have other potential applications, for example in reducing the cost of vehicle-mounted radar collision avoidance systems.

The IBM 7030, also known as Stretch, was IBM's first transistorized supercomputer. It was the fastest computer in the world from 1961 until the first CDC 6600 became operational in 1964.

Originally designed to meet a requirement formulated by Edward Teller at Lawrence Livermore National Laboratory, the first example was delivered to Los Alamos National Laboratory in 1961, and a second customized version, the IBM 7950 Harvest, to the National Security Agency in 1962. The Stretch at the Atomic Weapons Research Establishment at Aldermaston, England was heavily used by researchers there and at AERE Harwell, but only after the development of the S2 Fortran Compiler which was the first to add dynamic arrays, and which was later ported to the Ferranti Atlas of Atlas Computer Laboratory at Chilton.

Since the 7030 was much slower than expected and failed to meet its aggressive performance estimates, IBM was forced to drop its price from $13.5 million to only $7.78 million and withdrew the 7030 from sales to customers beyond those having already negotiated contracts. PC World magazine named Stretch one of the biggest project management failures in IT history.

Within IBM, being eclipsed by the smaller Control Data Corporation seemed hard to accept. The project lead, Stephen W. Dunwell, was initially blackballed for his role in the "failure", but as the success of the IBM System/360 became obvious, he was given an official apology and, in 1966 was made an IBM Fellow.

In spite of Stretch's failure to meet its own performance goals, it served as the basis for many of the design features of the successful IBM System/360, which shipped in 1964.

🔗 Computing 🔗 Computing/Computer hardware

Rekursiv was a computer processor designed by David M. Harland in the mid-1980s for Linn Smart Computing in Glasgow, Scotland. It was one of the few computer architectures intended to implement object-oriented concepts directly in hardware, a form of high-level language computer architecture. The Rekursiv operated directly on objects rather than bits, nibbles, bytes and words. Virtual memory was used as a persistent object store and unusually, the processor instruction set supported recursion (hence the name).

The project originated in an initiative within the hi-fi manufacturer Linn Products to improve its manufacturing automation systems, which at the time ran on a DEC VAX minicomputer. This resulted in the design of Lingo, an object-oriented programming language derived from Smalltalk and ALGOL. Due to the poor performance of Lingo on the VAX, a subsidiary company, Linn Smart Computing Ltd., was formed to develop a new processor to efficiently run Lingo.

The Rekursiv processor consisted of four gate-array chips named Numerik (32-bit ALU), Logik (instruction sequencer), Objekt (object-oriented memory management unit) and Klock (processor clock and support logic). A small number of prototype VMEbus boards, called Hades, comprising these four chips plus 80 MB of RAM were produced. These were intended for installation in a host system such as a Sun-3 workstation.

Although the Rekursiv was never fully developed and was not a commercial success, several Hades boards were used in academic research projects in the UK. The last known copy of a Rekursiv computer ended up at the bottom of the Forth and Clyde canal in Glasgow.

Pourquoi Pas? IV (English: Why Not? IV) was the fourth ship built for Jean-Baptiste Charcot, which completed the second Charcot expedition of the Antarctic regions from 1908 to 1910. Charcot died aboard when the ship was wrecked on 16 September 1936, off the coast of Iceland. Of the forty men on board, only one survived.
