Run Java Runtime on 256KB RAM

image
Indeed, with the release of Java ME Embedded 8.1, a full Java-runtime is now available on the Freescale K64F Board, which carries on Board 256KB RAM and has a processor based on the architecture of ARM Cortex M4. Another important feature of the new release of Java ME SDK is the support Eclipse IDE. Page new release of Java ME Embedded 8.1 here: http://www.oracle.com/technetwork/java/embedded/javame/embed-me/overview/index.html

/ > Platform Java ME Embedded 8.1 is specially designed to transfer all the useful functionality of Java on devices with limited hardware capabilities, and even microcontrollers. The emergence of platform Java ME Embedded, largely due to the development of a new direction in information technology, the Internet of Things (IOT). The development of the IoT is associated with new opportunities and new challenges. Part of tasks like security, network connectivity, communication with external interfaces UART, I2C, SPI, GPIO successfully solves the Java ME Embedded 8.1. The use of Java instead of native tools reduces the time of product release, and provides access to significant labor resources. By the way, did you know that the development team Java ME Embedded is almost entirely in Saint-Petersburg? What else made our developers you will learn more...


Some companies are already building on the basis of Java ME Embedded commercial products. For example, Gemalto launches 3G EHS5 and EHS6 modules http://m2m.gemalto.com/products/industrial/lga/ehs6.htmland the company ProSyst announced the creation of the mPRM — cloud service management and updates devices based on Java ME Embedded http://www.prosyst.com/about-us/news/detail/?tx_ttnews[tt_news]=51&cHash=c52a9db34219b226c722b9d7b08b9f0a Interest to use Java ME Embedded as a flexible alternative to native software platforms is growing since the release of Java ME Embedded 8, and version 8.1 is a logical continuation of success.

As I said, the new version brings Java ME Embedded world of microcontrollers processors with ARM Cortex M. Freescale K64F is a prototyping platform for Freescale Kinetis K64 series with a very attractive cost. Form factor K64F is compatible with Arduino R3 and allows you to use a lot of expansion cards. FRDM-K64F is built on the basis of the MK64FN1M0VLL12 MCU (120 MHz, 1 MB Flash, 256 KB RAM, low-power, crystal-less USB, and 100 Low profile Quad Flat Package (LQFP)). FRDM-K64F has a three-color diode and two buttons connected to the GPIO ports and the accelerometer-magnetometer FXOS8700Q. All built-in peripherals available and can be used in Java ME applications. As usual, the best way to start working with the platform to read the Getting Started Guide Getting Started Guide

About a week ago, all formal parties to the Eclipse PMC (Project Management Committee), Eclipse IP Team and the EMO (Eclipse Management Organization) approved release of the plugin Mobile Tools for Java TM (MTJ) 2.0, which is a Java ME SDK. Now to create applications in Eclipse Java EE to deploy and debug them on embedded platforms as simple as writing applications on Java SE for desktop.

Another nice new Java ME SDK 8.1 is the built-in programmers Java runtime for Freescale K64F. You can use it immediately after installing the Java ME SDK.
1. КликнитенаDevice Manager in Windows 8.1 Tray2. Click Flash and select your device in advance is connected via USB, K64F.
3. Enjoy: Java ME SDK independently flash your device with latest version of runtime Java ME Embedded 8.1

A Bunch Of MODx Revolution + LiveStreet

When going to write your topic, puzzled where to write it? On the one hand part of the site written in MODx, on the other hand the other part written on LiveStreet, and on the third hand these are crutches that at the time of Abnormal programming to write. It turned out that the Habr was preparing for such an eventuality and made the ability to write to multiple blogs, separate respect! :-) Well, now actually to the basic question: At the time I wrote and launched coupon service itself is written in MODx Revolution (of course, because I am an ardent fan of this engine and whatever you read, always write on this framework). So, the project grew and developed a lot of functionality, it was written (the benefit of MODx allows to solve any problem), but that's just me zamisliti on the site and more social programs-blog a La ... run, yeah to all of our users were there, Yes to reviews stock there got, the reviews were in stock, and in the social sphere, and here and there t...

Monitoring PostgreSQL with Zabbix

Изображение
PostgreSQL is a modern, dynamic DBMS with a very large set of possibilities which allow to solve a wide range of tasks. Using PostgreSQL as a rule refers to a very critical segment of the it infrastructure associated with the processing and data storage. Given the special place of the DBMS infrastructure and the criticality of tasks, the question of monitoring and appropriate control of the DBMS. In this respect, PostgreSQL has a wide internal means of collecting and storing statistics. Collected statistics allows to obtain quite a detailed picture about what is happening under the hood during operation of the DBMS. These statistics are stored in special system tables, views, and constantly updated. Performing regular SQL queries to these tables it is possible to obtain a variety of information about databases, tables, indexes and other DBMS subsystems. Below I describe the method and tools for monitoring PostgreSQL monitoring system Zabbix. I love this monitoring system becaus...

PostgreSQL load testing using JMeter, Yandex.Tank and Overload

Изображение
a Few words to start so, this manual is suitable for those looking for a versatile Toolkit for testing large pool of systems and solving most problems on stress testing. This article is intended for beginners in this business, so I will try to Refine and simplify the process. Discuss briefly each of the elements in our bunch and move on to their primary installation and configuration: the Apache JMeter – load testing tool, which is able to carry out tests for JDBC connections, FTP, LDAP, SOAP, JMS, POP3, IMAP, HTTP and TCP out of the box and many other protocols and solutions using various plugins. the Yandex.Tank is a cloud – based tool for load testing uses different load generators, including and JMeter. the Yandex.OverLoad – the service for easy monitoring and analysis of servers under load. the Installation and configuration the key to success for proper installation of JMeter is the correct java installation. At this stage it is worth saying that all the manip...
