LFE (programming language)

LFE (Lisp Flavored Erlang) is a functional, concurrent, general-purpose programming language and Lisp dialect built on top of Core Erlang and the Erlang Virtual Machine (BEAM). LFE builds on top of Erlang in order to provide a Lisp syntax for writing distributed, fault-tolerant, soft real-time, non-stop applications. LFE also extends Erlang to support meta-programming with Lisp macros and an improved developer experience with a feature-rich REPL.

History

Initial release

Initial work on LFE began in 2007, when Robert Virding started creating a prototype of Lisp running on Erlang. This work was focused primarily on parsing and exploring what an implementation might look like; no version control system was being used at the time, so tracking exact initial dates is somewhat problematic.

Robert Virding announced the first release of LFE on the "Erlang Questions" mail list in March 2008. This release of LFE was very limited: it did not handle recursive letrecs, binarys, receive, or try; it also did not support a Lisp shell.

Micro-PGA2

The Micro-PGA2, also known as the μPGA2, is Intel's pin grid array package for their Pentium III and some later Celeron mobile processors. It replaced its predecessor, Micro-PGA1, which was used in Pentium II and early Celeron mobile processors.

3-Phosphoglyceric acid

3-Phosphoglyceric acid (3PG), or glycerate 3-phosphate (GP), is a biochemically significant 3-carbon molecule that is a metabolic intermediate in both glycolysis and the Calvin cycle. This chemical is often termed PGA when referring to the Calvin cycle. In the Calvin cycle, 3-Phosphoglycerate is the product of the spontaneous split of an unstable 6-carbon intermediate formed by CO₂ fixation. Thus, two 3-phosphoglycerate molecules are produced for each molecule of CO₂ fixed.

Calvin cycle

In the light-independent reactions (also known as the Calvin cycle), two 3-phosphoglycerate molecules are synthesized, one of which continues through the Calvin cycle to be regenerated to Rubisco and the other is reduced to form one molecule of glyceraldehyde 3-phosphate (G3P). This is the first compound formed during the C3 or Calvin cycle. It is a reactive biomolecule that is easily reduced.

Socket 370

Socket 370 (also known as the PGA370 socket) is a common format of CPU socket first used by Intel for Pentium III and Celeron processors to replace the older Slot 1 CPU interface on personal computers. The "370" refers to the number of pin holes in the socket for CPU pins. Modern Socket 370 fittings are usually found on Mini-ITX motherboards and embedded systems.

Technical specifications

Socket 370 was originally used for the Intel Celeron, but later became the socket/platform for the Coppermine and Tualatin Pentium III processors, as well as the Via-Cyrix Cyrix III, later renamed the VIA C3. Some motherboards that used Socket 370 support Intel processors in dual CPU configurations. Others allowed the use of a Socket 370 or Slot 1 CPU, although not at the same time.

The weight of a Socket 370 CPU cooler should not exceed 180 grams (6.3 ounces). Heavier coolers may result in damage to the die when the system is not properly handled.

Proposed top-level domain

The Domain Name System of the Internet consists of a set of top-level domains which constitute the root domain of the hierarchical name space and database. In the growth of the Internet, it became desirable to expand the set of initially six generic top-level domains in 1984. As a result new top-level domain names have been proposed for implementation by ICANN. Such proposals included a variety of models ranging from adoption of policies for unrestricted gTLDs that could be registered by anyone for any purpose, to chartered gTLDs for specialized uses by specialized organizations. In October 2000, ICANN published a list of proposals for top-level domain strings it had received.

Geographic proposals

MED28

Mediator of RNA polymerase II transcription subunit 28 is an enzyme that in humans is encoded by the MED28 gene. It forms part of the Mediator complex.

Function

Subunit Med28 of the Mediator may function as a scaffolding protein within Mediator by maintaining the stability of a submodule within the head module, and components of this submodule act together in a gene-regulatory programme to suppress smooth muscle cell differentiation. Thus, mammalian Mediator subunit Med28 functions as a repressor of smooth muscle-cell differentiation, which could have implications for disorders associated with abnormalities in smooth muscle cell growth and differentiation, including atherosclerosis, asthma, hypertension, and smooth muscle tumours.

Interactions

MED28 has been shown to interact with Merlin,Grb2 and MED26.

MED6

Mediator of RNA polymerase II transcription subunit 6 is one of the subunits of the Mediator complex. It is an enzyme that in humans is encoded by the MED6 gene.

Protein family

This family of proteins represent the transcriptional mediator protein subunit 6 that is required for activation of many RNA polymerase II promoters and which are conserved from yeast to humans.
