Le Minitel, c'est fini ...

0 commentaires
Le fameux 3615 ferme ses portes. Lancé par France Telecom en 1982, le Minitel sera définitivement abandonné par Orange le 30 juin 2012.

Techniquement et économiquement, ce fut un véritable succès qui marque l'histoire de la technologie et des télécommunications : 20 milliards d'euros de recettes, des innovations majeures comme la prise Péritel, ou la mise au point de l'ADSL (avec Alcatel). 

Malgré un certain nombre d'innovations, Orange n'est pas parvenu - à ce jour - à réitérer l'exploit du Minitel. 

Respect pour les Ingénieurs de cette merveilleuse invention.

Read on SAP Newsroom
PALO ALTO — This week marks the one-year anniversary of the SAP HANA platform becoming generally available. To celebrate this occasion, SAP today announced the launch of the SAP HANA Distinguished Engineer program. The SAP HANA Distinguished Engineer program is a new group of community-driven, hands-on technical professionals focused on promoting SAP HANA expertise in the market. SAP is also honoring major milestones achieved with SAP HANA in the last year at an event being held this morning at SAP Labs in Palo Alto.
“In January, SAP HANA became the fastest-growing technology in SAP history, and this week we are celebrating its first anniversary,” said Dr. Vishal Sikka, member of the SAP Executive Board, Technology & Innovation. “Not only is SAP HANA revolutionizing our industry, it has also shown the power of technology to transform lives. In less than a year, SAP HANA has gained tremendous momentum with more than 350 customers, more than 150 implementations and more than 64,000 end-users. SAP HANA’s delivery of amazing business and technical value would not have been possible without the vision and support from innovative customers, startups and partners who have put their confidence in SAP HANA, but most importantly from an incredible team of warriors, who have done what once seemed impossible, in such a short period of time. SAP HANA is truly the embodiment of our intellectual renewal.”
Over the last year, SAP HANA has achieved major customer achievements and performance milestones[1]. Here are a few of the highlights:
Customer Achievements
  • 354 customers
  • 150+ implemented projects
  • 16 customers with more than 10,000-times performance improvement over disk-based databases
  • More than 64,000 end-users
  • 2,000 Amazon Web Services (AWS) instances
  • 1,791 trained consultants
Product Performance
  • One platform for OLTP and OLAP, structured and unstructured data, fresh data and “big data”
  • No tuning, no indices, no materialized views, no caching
  • 33 SAP solutions powered by SAP HANA
  • 100 TB benchmark on 16 node IBM X5
  • 20-times compression
  • Business warehouse (BW) query: 300-500 milliseconds
  • Ad-hoc query: 800 milliseconds-2 seconds
  • Insert rate: 770,000 records per second
  • Bulk: 1 GB per minute
  • Data services: 2.5 TB per hour
  • Scale out to 500 TB in main memory for real-time processing of “big data”
SAP HANA Distinguished Engineer Program to Foster Innovation, Promote Technical Skills
The SAP HANA Distinguished Engineer program was founded by SAP in collaboration with some of the foremost SAP HANA technologists and Mentors from Bluefin Solutions, Deloitte Consulting, IBM Global Business Solutions and independent consultants. It is open to all developers, database administrators and other SAP HANA technologists who have an interest in pursuing and promoting technical skills in support of SAP HANA-based customer solutions.
“We want to congratulate Vishal and the SAP team on the first anniversary of SAP HANA,” said Vijay Vijayasankar, head of SAP Forward Engineering, IBM Global Business Services. “The traction of SAP HANA in the market this past year is beyond anything else I have seen from SAP in my career. I also want to commend SAP specifically for supporting the fast-growing SAP HANA community – especially with the innovative idea of working closely with a community of SAP HANA experts to keep the skills in the ecosystem on the bleeding edge. This is key to ensure that customers and partners get the maximum benefit of SAP HANA. I am looking forward to even more collaboration and co-innovation with SAP in the future.”
With broad industry and partner support, SAP is committed to fostering innovation not only in software and hardware technology, but also in the growth and development of people and skills. SAP will work closely with program members to ensure skilled technologists stay up to date with the rapid pace of development of SAP HANA. The program will also help members gain access to resources from within SAP and cross-promote their efforts to drive new solutions and best practices based on SAP HANA.
