The Apache Software Foundation Announces Apache(tm) Mesos(tm) as a Top-Level Project

The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of nearly 150 Open Source projects and initiatives, announced today that Apache Mesos has graduated from the Apache Incubator to become a Top-Level Project (TLP), signifying that the project’s community and products have been well-governed under the ASF’s meritocratic process and principles.

Apache Mesos is a cluster manager that provides efficient resource isolation and sharing across distributed applications, or frameworks. It can run multiple frameworks, including Apache Hadoop, MPI, Hypertable, Jenkins, Storm, and Spark, as well as other applications and custom frameworks.

“It was our goal all along to see Mesos become a kernel of the infrastructure stack of the future,” said Benjamin Hindman, Vice President of Apache Mesos. “The project’s graduation from the Apache Incubator is recognition that the software is mature and has brought together a diverse community to sustain it in the future.”

Initially created at the University of California at Berkeley’s AMPLab (the research center also responsible for the original development of Apache Spark) to manage resource sharing and isolation in data centers, Mesos acts as a layer of abstraction between applications and pools of servers. Mesos helps avoid the necessity of creating separate clusters to run individual frameworks and instead making it possible to optimize how jobs are executed across shared machines.

Whilst in the Apache Incubator, Mesos had four releases, and established an Open Source community according to The Apache Way of governance. Additional improvements to the project includes its flexibility to support several application framework languages, and scalability that has been production tested to thousands of nodes and simulated to tens of thousands of nodes and hundreds of frameworks.

Apache Mesos has proven to be reliable for use in production, and has already been adopted by several organizations for cluster management.

“Mesos is the cornerstone of our elastic compute infrastructure,” explained Chris Fry, Senior Vice President of Engineering at Twitter. “It’s how we build all our new services and is critical for Twitter’s continued success at scale … one of the primary keys to our data infrastructure efficiency.”

“We’re using Mesos to manage cluster resources for most of our data infrastructure,” said Brenden Matthews, Engineer at Airbnb and Apache Mesos Committer. “We run Chronos, Storm, and Hadoop on top of Mesos in order to process petabytes of data.” (Chronos is an Airbnb-developed Mesos framework as a replacement for cron, and an example of how custom frameworks can be developed

SanDisk microSDHC and microSDXC Fastest Presents for 4G Smartphones

JAKARTA, WEDNESDAY – For owners of smartphones, tablets and digital cameras, microSD memory card with a large and fast-performing highly preferred. Especially if its a lot of HD video recording.

SanDisk listen to the demands and released what it claims is a world’s fastest memory card. Extreme SanDisk microSDHC and microSDXC UHS-I mentioned it is able to transfer up to 80Mbps and 50Mbps write on, or allow shooting shot-to-shot and faster continuous burst mode. This card, SanDisk said, is designed to support HD video and imaging in the future 4G smartphone. tablets and digital cameras.

The presence of this new card, SanDisk said, triggered by two things. The first is the smartphone. Because expected in the next year or the next, there will be about a billion new smartphones sold., And the average capacity of 6GB up in 2010 to 24GB in 2015. The smartphone users will begin using video and camera features are embedded in a smartphone. And 4G smartphones need faster memory.

The second driving force is the growing number of tablets being used as a personal device. And embedded memory in tablets will clearly be inadequate if the tablet is widely used for digital imaging activities.

Extreme Sandisk microSDHC memory cards and microSDXC available in capacities of 16GB, 32GB and 64GB. Price, depending on the capacity, range from U.S. $ 60 to U.S. $ 200.

Toshiba Ultrabook Presents Stylish Dual Function

JAKARTA – Toshiba introduced the latest generation ultrabook, named “Portege Z10t”. This super-thin notebook is presented in order to meet the needs of professionals who require a technology to carry anywhere but still stylish.

Channel Manager of the Computer Systems Division of Toshiba Singapore Pte. Ltd., Albert Susilo, said that now the tablet has become a popular gadget. Many of the professionals who always move with a laptop and a tablet.

“This is why we re-present the latest generation of ultrabook Portege Z10t, which has two dual function,” said Albert the introduction Portege Z10t in Jakarta, Thursday (4/7).

This Ultrabook has advantages over its predecessor, which is designed with a water-resistant keyboard. “Water resistant up to 55 ml, both mineral water, coffee, tea to sodas,” said Senior Manager Marketing Service Toshiba Singapore, Tay Choon Song.

Portege Z10t is a 11.6-inch touch screen notebook with full HD IPS, which has a dual function. Weighing just 850 grams and a thickness of 24 millimeters, Portege Z10t notebook can function as well as tablets.

With 4GB of RAM, Portege Z10t available in two sophisticated processors, the Intel i5 and i7. Unfortunately, Toshiba Portege Z10t only just released in a choice of colors, namely gray metallic.

In that event, also introduced also a special gaming laptop, the Qosmio X70. Latop which was created specifically for the game lovers is equipped with Nvidia GeForce GTX770M graphics technology, the memory capacity of up to 1TB. “This is an extreme laptop for enthusiast gamers,” added Tay Choon Song.

Variabel di Shell Script

In the previous issue we’ve become acquainted with a shell script and managed to create a very simple shell script. If we look, we did not perform any processing on the shell script. We only show a message on the screen and execute commands on the shell through shell script. What if we want to make the program more interactive shell script?

As with any programming language, shell script also serves to recognize the variables that can hold information temporarily for a variety of purposes, for example to compute or determine the output results. You may make as much as possible or use a variable in your shell script. Name the variables are independent, large and small letters should, but make it easier to remember, make it a habit to create standard rules in the manufacture of the variable name. At this writing, all variables will be written in lowercase.

Variables can be divided into two types, namely environment variables and user variables. Environment variables are variables that have been previously determined as a part of the shell used (bash). By default, the name of this variable using all capital letters. Example of this is the $ USER variable that will contain the user name you are currently using, $ HOME home directory which contains the address of the user that is used, and so forth. To display the entire value of an existing environment variable, you can use the set command in the terminal (Figure 1). User variable is the variable name specified by the user themselves and not by the shell used.

Variables can be accessed by using the dollar sign ($) before the variable name, for example, we have a variable named “my name”, to access the value stored in the variable, we use the $ my name. To give value to a variable, we use the sign “=” is immediately followed by the value we give without any spaces, for example my name = Willy. What if the value that we want to give is a sentence? Use double quotes as the opening and closing value of a variable, such as my name = “Willy Sudiarto Raharjo”. For example, see listing 1 and try running on your computer. Seen that the value of the variable Sudiarto be regarded as a command and not part of the variable because it is not enclosed in double quotation marks. Please be careful
