What is MyBatis

                         What is MyBatis

MyBatis is a Java persistence framework that couples objects with stored procedures or SQL statements using an XML descriptor or annotations.

MyBatis is free software that is distributed under the Apache License 2.0.

MyBatis is a fork of iBATIS 3.0 and is maintained by a team that includes the original creators of iBATIS.

Feature Summary

Unlike ORM frameworks, MyBatis does not map Java objects to database tables but Java methods to SQL statements.

MyBatis lets you use all your database functionality like stored procedures, views, queries of any complexity and vendor proprietary features. It is often a good choice for legacy or de-normalized databases or to obtain full control of SQL execution.

It simplifies coding compared to JDBC. SQL statements are executed with a single line.

MyBatis provides a mapping engine that maps SQL results to object trees in a declarative way.

NASA has in planning to use Ethereum (ETH) Blockchain technology for deep space exploration

NASA has in planning to use Ethereum (ETH) Blockchain technology for deep space exploration

This would be the first time when the blockchain technology will be used for space exploration

A research project funded by NASA is planning on using Ethereum blockchain technology to improve and automate spacecraft navigation and make space communication better. 

The project will be led by Dr. Jin Wei Kocsis, who is an assistant professor of electrical and computer engineering at the University of Akron. She has received a three-year $330,000 Early Career Faculty grant from NASA to develop a ‘Resilient Networking and Computing Paradigm’ [RNCP] that uses the blockchain technology underlying smart contracts, which don’t require mediation during transactions.

The aim of this project is to create a spacecraft that can ‘think’ by itself and ‘automatically detect and dodge floating debris’. This innovation is not only a faster and more effective way of detecting debris but also reduces dependence on the scientists ‘back home’, according to Wei Kocsis. In addition to working towards making the spacecraft ‘think’, Wei hopes to develop technology that will allow the spacecraft to complete tasks automatically and collect more data. 

Wei Kocsis says:

“In this project, the Ethereum blockchain technology will be exploited to develop a decentralized, secure, and cognitive networking and computing infrastructure for deep space exploration,”

She further adds: 

loading…

“The blockchain consensus protocols will be further explored to improve the resilience of the infrastructure.”

Thomas Kacpura, the Advanced Communications Program Manager at NASA’s Glenn Research Center says that this was the first time blockchain technology would be used for space communication and navigation. He also says that if the project is successful it “would support decentralized processing among NASA space network nodes in a secure fashion, resulting in a more responsive…. resilient scalable network that can integrate current and future networks in a consistent manner.”

He further adds: 

“It is expected that the potential is high to contribute to the next generation space networks, and also allow tech transition of these algorithms for commercial systems.”

Stephen Mark, a Twitter user said: 

“The potential of blockchain technology cannot be imagined and NASA proves it.” 

Nemanja, a Twitter user said: 

“Shouldn’t they use something that has HIGH ASSURANCE of working.”

Anthony Pompliano, managing partner at Full Tilt Capital said: 

“Forget the moon, it looks like crypto is going to deep space.”

What is Hibernate and Features

    What is Hibernate and Features

 

Hibernate ORM (Hibernate in short) is an object-relational mapping tool for the Java programming language. It provides a framework for mapping an object-oriented domain model to a relational database. Hibernate handles object-relational impedance mismatch problems by replacing direct, persistent database accesses with high-level object handling functions.

Hibernate is free software that is distributed under the GNU Lesser General Public License 2.1.

Hibernate's primary feature is mapping from Java classes to database tables, and mapping from Java data types to SQL data types. Hibernate also provides data query and retrieval facilities. It generates SQL calls and relieves the developer from the manual handling and object conversion of the result set.

 Hibernate Features

• Hibernate provides Object/Relational mappings. ...
• It provides different object oriented query languages. ...
• It provide transparent persistence without byte code processing.
• It introduces automatic Dirty Checking concept.
• It supports Detached object concept.
• It supports tough concept of composite keys.

NASA transiting Exoplanet Survey Satellite

SpaceX TESS Launch at 6:32 am Today    NASA in search of more exoplanets

            NASA transiting Exoplanet Survey Satellite, Exoplanet,SpaceX                                                                  

Meteorologists with the US Air Force 45th Space Wing have predicted an 80 percent chance of favorable weather for SpaceX Falcon 9 rocket's launch with NASA's payload Transiting Exoplanet Survey Satellite (TESS) aimed at detecting more exoplanets.

The launch is scheduled for Sunday at 6.32 p.m. local time on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida, said NASA in a statement late Saturday.

The launch window is just 30 seconds and weather not favourable, the liftoff will be deferred by two more weeks when the moon comes nearer to the Earth. The launch is linked to moon's gravitation pull, which is essential for placing TESS in its unique orbit that nobody tried in the past, said scientists.

Joel Villasenor, an MIT researcher and instrument scientist for TESS explains, "The moon pulls the satellite on one side, and by the time TESS completes one orbit, the moon is on the other side tugging in the opposite direction. The overall effect is the moon's pull is evened out, and it's a very stable configuration over many years. Nobody's done this before, and I suspect other programs will try to use this orbit later on."

The Transit Exoplanet Survey Satellite is a successor to the Kepler, which has already located thousands of exoplanets over a decade. Unlike Kepler's telephotos aimed at dim targets far in the distance, TESS has an ultra-wide-angle lens to scan the entire visible sky.

All about Artificial intelligence

                               All about Artificial intelligence

Artificial intelligence (AI) is the ability of a computer program or a machine to think and learn. It is also a field of study which tries to make computers "smart". John McCarthy came up with the name "artificial intelligence" in 1955.
In general use, the term "artificial intelligence" means a machine which mimics human cognition. At least some of the things we associate with other minds, such as learning and problem solving can be done by computers, though not in the same way as we do.
An extreme goal of AI research is to create computer programs that can learn, solve problems, and think logically. In practice, however, most applications have picked on problems which computers can do well. Searching data bases and doing calculations are things computers do better than people. On the other hand, "perceiving its environment" in any real sense is way beyond present-day computing.
An example is Deep Blue, the IBM chess program that beat Garry Kasparov in the 1990s. Deep Blue can identify pieces on the chess board and make predictions, but it has no memory and cannot use past experiences to inform future ones. It analyzes possible moves -- its own and its opponent -- and chooses the most strategic move.
