Flask (web framework)

Flask is a micro web framework written in Python and based on the Werkzeug toolkit and Jinja2 template engine. It is BSD licensed.

As of 2015, the latest stable version of Flask is 0.10.1. Examples of applications that make use of the Flask framework are Pinterest, LinkedIn, as well as the community web page for Flask itself.

Flask is called a micro framework because it does not presume or force a developer to use a particular tool or library. It has no database abstraction layer, form validation, or any other components where pre-existing third-party libraries provide common functions. However, Flask supports extensions that can add application features as if they were implemented in Flask itself. Extensions exist for object-relational mappers, form validation, upload handling, various open authentication technologies and several common framework related tools.

History

Flask was created by Armin Ronacher of Pocoo which is an international group of Python enthusiasts formed in 2004. According to Armin, "It came out of an April Fool's joke but proved popular enough to make into a serious application in its own right." Flask is based on the Werkzeug WSGI toolkit and Jinja2 template engine, both of them Pocoo projects that were created when Ronacher and Georg Brandl were building a bulletin board system written in Python.

Flask (casting)

A flask is a type of tooling used to contain a mold in metal casting. A flask has only sides, and no top or bottom, and forms a frame around the mold, which is typically made of molding sand. The shape of a flask may be square, rectangular, round or any convenient shape. A flask can be any size so long as it is larger than the pattern being used to make the sand mold. Flasks are commonly made of steel, aluminum or even wood. A simple flask has two parts, the cope and the drag, and more elaborate flasks may have three or even four parts.

Flask Design

Flasks are often designed with bars which extend span two opposite sides. The bars act as reinforcement to the molding sand which is relatively weak in tensile strength. The bars help support the sand through the molding and pouring operation.

Flasks are designed with an alignment or registration feature so that the two flasks can be aligned to one another to insure a casting can be more dimensionally accurate.

Flasks will usually have handles or trunnions designed into their construction which assist in handling the flasks with cranes or other lifting machinery.

Artà

Coordinates: 39°42′N 3°21′E / 39.700°N 3.350°E / 39.700; 3.350

Artà is one of the 53 independent municipalities on the Spanish Balearic island of Majorca. The small town of the same name is the administrative seat of this municipality in the region (Comarca) of Llevant.

Population

In 2008 the municipality of Artà had a population of 7,113 recorded residents within an area of 139.63 square kilometres (53.91 sq mi). This equates to 50.9 inhabitants per km². In 2006 the percentage of foreigners was 13.2% (890), of which Germans made up 3.9% (262). In 1991 there were still 136 illiterates in the municipality. 1,292 inhabitants had no education, 1,675 only a primary school certificate and 1,210 had secondary school leaving certificates. The official languages are Catalan and Spanish (Castilian). The Catalan dialect spoken on the island is known as Mallorquí.

Geography

Location

Artà lies in the northeast of the island of Majorca, around 60 km from the island's capital of Palma. The Massís d’Artà, the highest and most compact massif in the eastern mountain chain of the Serres de Llevant, occupies more than half the area of the municipality. The municipality is located on the western part of peninsula of Artà and is bordered in the west by the Bay of Alcúdia (Badia d’Alcúdia), and in the north by the Mediterranean sea where its coast lies opposite the neighbouring island of Minorca. The coast of Artà stretches for 25 kilometres and, so far, has escaped being developed. Particularly noteworthy are the beach and sand dune formations of sa Canova d’Artà, the flat coastal strip near the settlement of Colònia de Sant Pere, the high rocky coves of the Cap de Ferrutx and a large number of smaller bays that extend from s’Arenalet des Verger to Cala Torta.

ART image file format

ART is a proprietary image file format used mostly by the America Online (AOL) service and client software.

Technical details

The ART format (file extension ".art") holds a single still image that has been highly compressed. The format was designed to facilitate the quick downloading of images, among other things. Originally, the compression was developed by the Johnson-Grace Company, which was then acquired by AOL. When an image is converted to the ART format, the image is analyzed and the software decides what compression technique would be best. The ART format has similarities to the progressive JPEG format, and certain attributes of the ART format can lead to image quality being sacrificed for the sake of image compression (for instance, the image's color palette can be limited.)

Usage by AOL

The AOL service used the ART image format for most of the image presentation of the online service. In addition, the AOL client's web browser also automatically served such images in the ART format to achieve faster downloads on the slower dialup connections that were prevalent in those days. This conversion was done in the AOL proxy servers and could be optionally disabled by the user. This image conversion process effectively reduced the download time for image files. This technology was once branded as Turboweb and is now known as AOL TopSpeed.
