I will try to stay around in the community because for this 2.5 years Hazelcast has become a big part of my life!

Fri, 09 Sep 2016 00:00:00 +0000

TL;DR

Rejoice, JavaScript people! There are many new features in Hazelcast Node.js Client 0.4.1. In the 10 minutes, you spend reading this blog I will cover "what’s new"! Also, if you read this blog post till the end, you will also learn what’s coming to future releases.

It has been a while since out first blog post on Hazelcast Node.js Client ^[1]. Our brave developers have been very busy adding new features and making Hazelcast Node.js Client faster!

Getting Started with Hazelcast and Node.js

Mon, 18 Apr 2016 00:00:00 +0000

TL;DR

Install the package npm install hazelcast-client, grab a demo app and read API docs. Time To «Hello World!» less than 5 min.

On the behalf of Hazelcast Team, I’m pleased to announce the availability of version 0.2 of the Hazelcast Client for Node.js.

The new version includes following features:

IMap

Node.js client supports following operations of IMap - get, put, remove.
Smart Client

A client connects to each cluster node. Since each data partition uses the well known and consistent hashing algorithm, each client can send an operation to the relevant cluster node. This increases the overall throughput and efficiency. Plus, you don’t need to restart the client when adding or removing nodes from the cluster.

My Year At Hazelcast In Review

Tue, 29 Dec 2015 00:00:00 +0000

TL;DR

It has been an awesome year full traveling (roughly 20 states), POCs for the clients and the prospects, training (including public classes) and conference talks. While I am already looking forward to 2016, here is a quick recap of my 2015 with Hazelcast.

2015 has been a helluva of a year for me, which started off with a new job: the Solutions Architect in Hazelcast - Open Source In-Memory Data Grid company. In addition to travelling to over 20 states, I had numerous opportunities to share my programming experience and how to develop and deploy the distributed systems. I enjoyed the conference talks, blog posts, and podcasts (1, 2, 3 in Russian).

Hazelcast for MongoDB Developers

Mon, 02 Nov 2015 00:00:00 +0000

TL;DR

When I talk to the developers about Hazelcast, many of them ask how Hazelcast is different from NOSQL databases, and particularly from MongoDB. In this blog post, I will try to answer this question once and for all.

Introduction

MongoDB is an open source, document-oriented database designed with both scalability and developer agility in mind. Instead of storing your data in tables and rows as you would with a relational database, in MongoDB you store JSON-like documents with a dynamic schema. In short, MongoDB is an NOSQL data store, primarily concerned with storing/persisting and retrieving schema-free data.

Ground-up Introduction To In-Memory Data

Tue, 27 Jan 2015 00:00:00 +0000

TL;DR

This April, I’m going to deliver half-day workshop «Ground-up Introduction To In-Memory Data» at Code PaLOUsa conference in Louisville, KY.

You’re an architect or a developer with years of experience creating amazing applications. You’ve just been assigned to a gasp low latency project! Because you’re an expert, you’re expected to master a new In-Memory caching/data technology and be productive from day 1. You feel completely lost as you open the JAR files. Not only that, but you have to contend with new topologies and data stores like NoSQL or Hadoop.

Goodbye, Farata. Hello, Hazelcast!

Sat, 13 Dec 2014 00:00:00 +0000

Go for it now. The future is promised to no one.

— Wayne Dyer

TL;DR

Monday, December 15, I’m staring my new role as Solutions Architect at Hazelcast.

I’ve had a great time at Farata Systems over the past 4 years and 3 months. It was my first workplace in US, and it was incredible place to work. During that period, I learned so many technologies, tools, frameworks and even languages so I can say with confidence that it was quite a ride!

I'm speaking at JavaOne 2013

Tue, 09 Jul 2013 00:00:00 +0000

New achievement unlocked - I’m going to deliver the talk at JavaOne 2013! This year I will be talking about very demanding and interesting topic for me - about integration Java and JavaScript.

Here is quick abstract of my [BOF5793] session:

"" There is a perception in the Java community that JavaScript is a second-rate interpreted language whose main purpose is to make Web pages a little prettier. But JavaScript is actually a powerful, flexible, dynamically typed language. And today the language has been experiencing a revival driven by the interest in HTML5. Nashorn is a modern JavaScript engine available on the JVM, and it’s already included with JDK8 builds. This presentation is about building polyglot applications with Java and JavaScript. ""

Productive Enterprise Web Development with ExtJS and Clear Data Builder

Tue, 05 Feb 2013 00:00:00 +0000

It will not likely that you will start developing an enterprise HTML5 applications without using one of the JavaScript frameworks. One of the most feature-complete frameworks is ExtJS from Sencha, but its learning curve is a bit steep. Our company, Farata Systems, has developed an open source software Clear Toolkit for ExtJS. Clear Toolkit includes an Eclipse plugin called Clear Data Builder (CDB). It is a productivity tool - a code generator - that can create a CRUD application for you in no time. This application will have HTML/JavaScript/ExtJS client and Java-based server. In this article, you will learn how jumpstart development of such Web applications.

I did an overview of the servers (including upcoming JavaEE 7 RI - Glassfish 4) and frameworks that support WebSockets and showed some use cases where WebSockets shine. At the end we had short conversation about various approaches for the server- and client-side implementations of WebSockets that can be used in the Web applications today.

Alfred Extension: Show/Hide desktop icons on Mac OS X

Mon, 21 May 2012 00:00:00 +0000

For some reasons, I’m using desktop as temporary storage of files - downloaded from internet, in-progress documents, screenshots and code snippets. Time after time I create screencasts and I need to have clean desktop. First, I tried to find available solution and have found Desktop Curtain. I don’t need all this fanciness (different desktop wallpapers, customization) so $2.99 is overkill for me and for this taks. So, I decide to create my own solution with help of shell and Alfred. Googled for Mac OS X command and I created simple script what I wrapped after as Alfred Extension. You can download Alfred Extension for my Dropbox. To use it you need to have Alfred PowerPack purchased. Cheers

WebJars for assets management in your project

Wed, 16 May 2012 00:00:00 +0000

Usage automatic build tools for dependency management is best practice in Java world and usage of tools such as Maven has been proven by the years. But what if utilize existing Maven knowledge of Java dependencies management for JavaScript projects. Hopefully, some Java and JVM frameworks (like Grails or Play2) provided their own way of dealing with static resources. But in most common situations, you don’t have lot of options for deployment your application.

From my humble opinion, InfoQ is one of best resources for developers nowadays. You can find lot of IT related stuff - interviews, articles, presentations slides and videos. And today I would like to talk about videos from InfoQ in particular. Is always good to have offline version to watch it during long commute, for instance. Unfortunately, InfoQ administration for some reasons not allow to download videos.
However, I found very elegant solution how to do that. I did it on my MacOS X with Safari, probably it will work with Safari for Windows as well.

Last weekend spend in setup of environment for eclipse plug-in development. I have task to fix and update one plugin. This is add-on to Flash Builder. But before adding something, it’s good to run that plugin before. My environment is Mac OS X 10.7 Lion, Eclipse 3.6 (32bit because FB not supported 64bit version of Eclipse) and Flash Builder 4.5. But I faced with odd exception

Mac OS X shipped with 2 versions of JVM - 32 bit and 64 bit accordingly. So, First I tried to change order of JVM preference from /Application/Utilities/Java Preferences but it didn’t work.

Building and Testing with Gradle - My Book Review

Sun, 10 Jul 2011 00:00:00 +0000

Last month I participated in JAXConf conference on San Jose, CA. There was many talks related to agile development and code quality stuff. And after that event I started looking to Gradle - next generation build tool. Couple weeks later I found a Building and Testing with Gradle written by git evangelists Tim Berglundand ( @tlberglund) and Matthew McCullough (@matthewmccull).

Book very focused and easy to read. I got my dirty cheap ebook version on thursday night, read this book during my commute to work and now come up with this review.
