Dessie is located along Ethiopian Highway 1. It has postal service (a post office was established in the 1920s), and telephone service from at least as early as 1954. The city has had electrical power since at least 1963 when a new diesel-powered electric power station with a power line to Kombolcha was completed, at a cost of Eth$ 110,000. Intercity bus service is provided by the Selam Bus Line Share Company. Dessie shares Combolcha Airport (ICAO code HADC, IATA DSE) with neighbouring Kombolcha.
Dessie is home to a museum, in the former home of Dejazmach Yoseph Birru. It also has a zawiya of the Qadiriyya order of Islam, which was the first Sufi order to be introduced into north-east Africa.
The original DES cipher's key size of 56 bits was generally sufficient when that algorithm was designed, but the availability of increasing computational power made brute-force attacks feasible. Triple DES provides a relatively simple method of increasing the key size of DES to protect against such attacks, without the need to design a completely new block cipher algorithm.
The Triple Data Encryption Algorithm (TDEA) is defined in each of:
ANS X9.52-1998 Triple Data Encryption Algorithm Modes of Operation (withdrawn)
FIPS PUB 46-3 Data Encryption Standard (DES) (does not include keying options) (withdrawn)
NIST Special Publication 800-67 Revision 1 Recommendation for the Triple Data Encryption Algorithm (TDEA) Block Cipher
In 2008 the municipality of Artà had a population of 7,113 recorded residents within an area of 139.63 square kilometres (53.91sqmi). This equates to 50.9inhabitants perkm2. In 2006 the percentage of foreigners was 13.2% (890), of which Germans made up 3.9% (262). In 1991 there were still 136illiterates in the municipality. 1,292inhabitants had no education, 1,675only a primary school certificate and 1,210had secondary school leaving certificates. The official languages are Catalan and Spanish (Castilian). The Catalan dialect spoken on the island is known as Mallorquí.
Artà lies in the northeast of the island of Majorca, around 60km 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 25kilometres 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.
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.
