I ‘ve been using so many different tools and techniques in the past, but nothing worked as reliable and fast as AJAX. In our family, I ‘m the one who cleans dishes that don ‘t fit in the dishwasher. No other cleanser works as good as AJAX.

I believe that popularity of AJAX chemicals contributes to popularity of AJAX as techniques for development of rich Internet applications. These techniques where known for more than six years, but only after the term AJAX was coined, it took off. Software developers are regular people and working with a tool at work that has the same name as something they use at home on a daily basis helps.

Microsoft came out with their tool for developing RIA called WPF. This acronym is not very familiar to people yet. Bill, if you read this blog, I “ve got an advice for you – purchase the rights for the WD-40 brand. This is a respected household name, and lots of IT managers grew up spraying everything that squeaks with this magic liquid.

Now it becomes clear why Java Swing is having hard times in RIA – people do not swing as often as they use Ajax.

Take Open Laszlo ndash; it sounds like something Hungarian. Guys, you have a nice tool but most of your customers are not from Budapest ndash; re-brand it.

On the same note, I have a suggestion to the newly appointed Adobe head of global sales: purchase a micro-brewery that produces good beer, change its label to Flex and start shipping gift-wrapped cases of this beer to enterprise IT development managers. This is a how you win minds of decision makers. Besides, it “s a lot cheaper than purchasing online banners or real estate in professional magazines for advertisement.

This is what came to my mind after the New Year celebration. No, I did not drink too much.

In his recent post Joel Spolsky writes about whether bloggers should accept gifts from vendors. Here ‘s my two cents on the subject.

Every blogger wants to have large readership of people who trust him or her. If a blogger writes that a product XYZ is good, readers believe that it “s an honest opinion of the blogger at the moment.

Up till today, I have not received and gifts from any vendors. You know why? Because, no one has offered me anything substantial yet. Actually, this is not exactly right. I do receive free books from publishers, and if I like the books, I publish reviews, if I do not – I keep my mouth shut. I ‘ve also received two free IDEs licenses: IntelliJIDEA and FlexBuilder. I really liked the first one (and praised it online), but the second one needs improvements, and I wrote about it without thinking twice.

If someone will send me free stuff in the future, most likely I will accept it. But I can promise that I won “t publish a good review unless I like the product.

So I do not think it “s either good or bad to accept free laptop samples, but if you decide to accept it, do not feel any obligations and write about them what you think.

When I saw the blue screen the first time, I thought that it “s an accident. But then it started happening every ten minutes or so hellip;It “s my second Dell laptop, the first one “s motherboard died when it was 2 years old. I got another Dell just to be able to reuse some remnants from the first one. This one has also lasted for about two years, and the warranty is over. It gave me all kinds of messages about memory failure – I played with memory chips, ran chkdsk ndash; did not help.

Then I called Dell tech support (I still have the phone tech support). When their technician asked me about the error code on my blue screen and said that he needs to do some research on Yahoo, I realized that the case is closed. Then annoying email and automated follow up phone call to show off their “care about customers rdquo;.

Anyway Dell is over. It “s a matter of weeks now. What “s next? This is what I need:

The monitor has to be small 12-13 inches, because when the person in front of you on the bus or plane lowers her seat, I do not want to move the laptop on my roundish belly.

I do not get why people pay top dollars for laptops with 17 inch monitors? It makes a lot of sense (and is a lot cheaper) to by a laptop with a small monitor and separately a large monitor to use at home, if needed. I also need 1Gb of RAM, 1.8Ghz CPU and 40Gb hard disk and DVD drive.

Several people told me that IBM (Lenovo) uses better parts then Dell. Another person I trust told me that Macbook Pro is a way to go. When I asked him why he would not by one for himself, he sadly replied, “Unfortunately I have two laptops that still work rdquo;. Poor thing!

Yes, I “m thinking of Mac laptop. 13 inches monitor, 1GB, dual boot ndash; Windows and OS X. Having this notebook will make me even cooler, and Windows is going to be my safety net if something goes wrong in the unusual territory.

Do you have any experience/suggestions in this regard?

Recently I ‘ve got an email from a person saying that he created his personal blog, and was wondering if I could have suggested a topic to blog about.

IMHO, there is no need to search for topics. Just listen, look and pay attention to what ‘s happening around you. For example, five minutes ago I was passing by a cubicle where one Indian asked another, “How was your Christmas? “. A regular person would not pay attention, but a blogger would immediately blog. It can be something like this:

Any religion (don ‘t confuse with faith) is business. And as such, it becomes a part of our lifes. Retailers capitalize big time on the Christmas season craze – people MUST buy gifts. In New York, you can find tons of small stores own by muslims that decorated their windows with Christmas trees and Hanukah candles. It ‘s business. Technically, every corporation does the same thing in their offices. Christmas is a good topic for a small talk between colleagues. Christmas is a good reason to pick up your ass and get your kids to see the main tree in your town. Finally, Christmas is a holiday, which turns your regular weekend into a long one.

Some studies suggest that December 25 is not actually the DOB of JC. Is this important? Is your religion (or its abscence) important? Not at all. Chrismas puts all of us into good holiday mood. Crusades are forgotten, and today ‘s Christmas is represented by a kind looking Santa, twenty portions of Jingle Bells a day, Let it Snow and all other non-offensive stuff.

So Merry Christma-hanu-kwanza!

That ‘s all folks. The blog is ready. The subject is not well researched. But it ‘s an easy read and easy write.

Fine print: I blog over here on more serious and technical issues

I “ve received Fedex with two documents: instructions on how to pee in the cup and a letter of consent to sign that I agree to do this. As a consultant working for financial clients, I have to go through the drug test quite often ndash; this is my third time during the last 12 months. This made me thinking (again and again) about the freedom that exists in theory here in the USA, and most likely the situation is the same in other countries.

Let “s see. I have a freedom of not peeing in the cap, but, if I exercise this freedom, I won “t get this job. But I want this job to support my family and my current life style. This means that even though theoretically, I have a freedom of not peeing when I “m being told to do so, I “d better pee.

The situation is the same with all kind of background checks. Last year, I had to go through a criminal background check in the sate of Georgia (sure enough I “ve signed the paper that I agreed with this). I have no idea why this firm is particularly interested if I did not kill anyone in Georgia. I firmly believe that killing people is bad in any sate, city or country.

The USA citizens are not required to have passports, which is praised by many non-Americans as a great sign of true freedom. Is it, really? Yes, you do not have to have a passport if you are not planning to cross the border for business, travel or any other reason. In many cases though you need a state photo id, like driver license. Just try to get it ndash; there is a point system of other documents you have to provide proofs that you are who you say you are. You need to present documents that worth six points, for example, American passport (worth only 3 points), a utility bill (1 point), a credit card (1 point) etc.

So having a freedom of not having any id does not exist in the real world.

You have a freedom to say what you really think to you boss. You may lose your bonus, but who cares, if you want to be free hellip;

Americans are ready to trade their freedom easily for something more tangible. They like borrowing money. Most of the people who live in “their ” houses do not own them – up to a 100% of the money for the house were “given ” by the bank. And because of this, people will put up with all BS around them, will be polite and smiley , but not free…

I know of only one group of people who are really free in the USA: homeless. They do not have anything to lose, most of them have chosen this way of life voluntarily, and they can say anything to anyone, without thinking twice.

People in the USA are free to live anywhere they like. Some time ago I “ve been driving in Manhattan with a friend, and she said, “I “d love to live in Manhattan, but it “s so expensive! rdquo; Sure enough, we saw a homeless person sitting on a sidewalk. I said, “Look, people who really want to live in Manhattan, do not try to find any excuses ndash; they just live here rdquo;.

Blogging hellip;Is blogging is really free? When I blog, I try not to engage any brakes, but is it possible? Where is the line between using my freedom of blogging and offending someone? Typically, I blog about whatever comes to my mind or whatever I see now. This is my attempt to exercise my freedom. Unfortunately, I have to admit that once in a while I re-read my old blogs and either delete or modify them to make them more appropriate according to the current common understanding of what appropriate is.

What did I write all this? I have no idea. I have a freedom of writing it, and you have a freedom of not reading it.

The New Year 2007 is almost here. But let ‘s look back for a moment. This is my list of five most annoying things of 2006.

1. The batteries. There ‘s gotta be a way to seriously extend the life of the batteries on my laptop and cell phone. Can someone take care of this in the 21st century?

2. The Internet is sloooooow. You can call it broadband, cable modem, DSL, you can give us as many fixed benchmarks you like, but it ‘s slooooow. There is a hope though – Verizon offers optical connection in some areas, and Chinese made a discovery .

3. Commute. Typically, I spend a little more than three hours a day commuting to/from work. I found my ways to make it a little less annoying by using my laptop (see annoyance #1 above) with the broadband Internet (see annoyance #2 above) on the bus. But why do I have to physically be there every day? I can and should work from home. Do you think that if you let me do this I ‘ll be taking care of some personal stuff during business hours? I ‘ll do it anyway, but I personally work more when I work from home

4. Junk mail. I casually delete tons of junk mails every day. Guys and gals, I do not need any loans, viagra or stocks. They won ‘t listen…

5. Firewalls. They make the annoyance #2 even more annoying.

Other than these five little unavoidable realities of life – no complains.

What annoys you the most (other than this blog)?

Update: when I came home tonight, I found a Fedex envelope and realized that I forgot to mention one more annoying thing – peeing in the cup. As a consultant working for financial companies, I ‘m going through a drug test third time during the last 12 months. This Fedex had special forms and a list of the closest labs where I can do this…

The book “RIA with Adobe Flex and Java ” is written. Check out the book site. Do you know why we are smiling? Because the book writing is over! It took us longer than planned because we had to work for a living, and the time for writing this book was just stolen from our families and our sleep.

The book is about 650 pages, and here ‘s the brief TOC:

Foreword by Bruce Eckel

Foreword by Matt Chotin

Chapter 1. Architecture of RIA

Chapter 2. Introduction to Flex Framework

Chapter 3. Flex Builder Development Environment

Chapter 4. Learning Flex Through Applications

Chapter 5. A Complete Application with RPC Communications

Chapter 6. End-to-End Rapid Application Development

Chapter 7. How to write your own data services

Chapter 8. Enhancing and Extending Flex Controls

Chapter 9. Trees with Dynamic Data Population

Chapter 10. Working with Large Applications

Chapter 11. Data-Driven Approach To Flex Programming

Chapter 12. Application logging and debugging

Chapter 13. Building a SlideShow Application

Chapter 14. Developing Custom Charts

Chapter 15. Integration With External Applications

The book should be printed in February 2007. Most of the book is a heavy duty stuff that will be useful for any real-world Flex developer. The first four chapters go easy on you, but then we start going deep under the Flex 2 skin. We are sure that this book is going to be useful for any Flex practitioner. We hope that this book will be appreciated by Java developers, even though a reader with any object-oriented background will be able to use it.

This was my fourth book. And it ‘s the fourth time when I say, “Never again “. Let ‘s see if I ‘ll be able to keep the promise this time.

I ‘ve got the following message in one the online forums: “I think you need to get over your hatred of Javascript Yakov “. This is my quick response:

Let me remind you an old joke:

-Joe, do you like tomatoes?

-I like to eat them, otherwise…not really

I do not love or hate programming languages – I use them. Having the need to execute ten pounds of code of any interpreted/platform dependent language in a non-standardized environment such as a Web browser is bad. In the case of Ajax, it ‘s a lot of JavaScript per Web application, and I do not like THIS USE of JavaScript.

I do not have anything against JavaScript when it comes to beautifying the user ‘s Web page, nice visual effects, some client-side validation, passing data between various applications that are part of a Web page. But I ‘d prefer running my programs in a VM, being that JVM, Flash Player, or anything else.

This was a five-week Adobe Flex evening class at New York University, one of the top-tier schools in the USA. When I found out that eighty percent of my students were Java programmers, I decided to turn this class into an intensive training experience. This was a hands-on class, plus students were working on their own on home works (complete working applications) between the sessions. For each class I ‘ve given 15-page custom-made handout, and here ‘s a quick summary of what I ‘ve covered:

Session 1. Architecture of Rich Internet Applications. Hands-n demo of an …AJAX application. Flex Builder. Development of a calculator.

Session 2. States, ActionScript, List-based controls, Data Binding – multiple use cases

Session 3. XML with E4X, Namespaces, Five different ways of programming in Flex depending on your background, Regular Expressions.

Session 4. Flex-JSP communication, Events, custom components

Session 5. A lab on custom events. Detailed code review of an application utilizing Flex remoting with RemoteObject, HTTPService

In the beginning of each class I ‘d ask students to stop me if I was moving too fast. They ‘d say, “We ‘re fine, go ahead “. At the end of the class students asked for the next, more advanced class. Universities do not add new classes to their programs too often, but NYU deserves lots of credits for being an early adopter of Adobe Flex 2. They did not include advanced class in their program yet, but I ‘ll re-run the same class in April. Re-run is a wrong word here, because I always teach something different. Money-wise, this class was an absolute bargain – only six hundred bucks for five evenings with me. Hmm, does it sound like a whore ‘s statement? Nope. Pretty Woman? Yakov, stop it, we are talking about EDUCATION here, get serious, will you! OK, OK. Sorry. No, just one more…singing…We do not need no education…Pink Floyd…

Beside NYU I ‘ll be co-teaching one day Flex Workshop at a famous AjaxWorld conference in March and private corporate gigs in the USA and Europe (btw, would love to go to India while it ‘s not too hot there). I ‘m also wondering if there is a huge demand in Adobe Certified Flex Instructors in Hawaii, Paris, Tokyo and Bangkok?

We are approaching 2007, I ‘ll try to take my guess about what ‘s going to happen in the IT world.

1. Open sourcing Java won ‘t matter – it ‘s a non-event.

2. Ruby and Ruby on Rails won ‘t make it in 2007 either. I still do not see a compelling reason to switch.

3. Ajax hype is stronger than I thought mainly because of the life support offered by frameworks like GWT. But still, I ‘m not going to recommend enterprise IT shops make any serious investments in AJAX.

4. We are going to watch some interesting competition in the RIA arena between Adobe ‘s Flex and Microsoft ‘s WPF/E. Adobe has more mature technology, while Microsoft is an established player among enterprise developers. I won ‘t be surprised if Adobe will dramatically drop the licensing fees for their Flex Data Services.

5. Java remains the best choice for the server side enterprise development, but it won ‘t be able to compete on the desktop.

6. IT outsourcing remains a part of our lives despite (or because of) the poor management by American corporate IT staff, and the reason is not the lower labor cost of overseas programmers, but the abcence of programmers in the USA.

7. Switch from plain stateless text-based to rich internet applications will slowly continue. But this won ‘t be an easy process – it ‘s not that easy to get rid of these annoying but familiar habits of dealing with one-page-at-a-time applications. The fight for the Back button on the Web browser will continue.

8. I ‘m not going to afford an early retirement. Let me go and buy this lottery ticket for tonight ‘s mega millions…
