On average, I pass the airport security four times a month either on business
or as a tourist. Over the years I became a living proof that Pavlov’s
finding about conditioned reflexes were correct.
When I see an airport, I start pulling off my belt, taking off my shoes, and
my hands are unzipping my laptop bag. Everyone knows that keeping the
notebook in a separate tray while passing this X-Ray machine makes your
flight safer. Nobody knows why though.
Last week, the New York Times published an article titled “The Mystery of
the Flying Laptop”, where Matt Ritchel tried to find the reason WHY you
have to pull the laptop from your bag, but tablets or smartphones can sit
inside… in some airports. He was talking to different people from the
Transportation Security Administration (a.k.a. TSA), but no one seemed to
know the answer.
Finally, one security expert offered the f... (more)
Clear Data Builder for Ext JS (CDBExt) is an open source tool that
automatically builds Ext JS/Java EE CRUD applications given one or more
annotated Java interfaces. The generated JavaScript and Java code enforce
best Ext JS and Java EE practices and is deployed on the development version
of the Tomcat ready to run.
A tiny library of Ext JS components accompanying CDBExt – Clear components
– enables transactional data sync with the application server, including
deeply nested hierarchical data transaction, features not supported in native
Ext JS 4.

About six years ago I wrote a blog titled “I have no idea what Web 2.0
means“. That blog had link to a video where IT leaders were helplessly
trying to explain what Web 2.0 means. One guy said something like this,
“Everyone wants to do it, and you can’t find enough people to do it”.
I still believe Web 2.0 was nothing else but a catchy marketing term, which
helped selling such events as Web 2.0 Expo, Web 2.0 Summit, and helped
Forrester in selling their typical 7-page-for-1000-bucks-zero-info reports
(this one was quietly removed).
The Web 2.0 term is fully milked out and the... (more)
JDJ's Enterprise Editor, Yakov Fain (pictured) writes: If you are planning to
hit the job market, you may need to refresh some of the Java basic terms
and techniques to prepare yourself for a technical interview. Let me offer
you some of the core Java questions that you might expect during the
interviews.
For most questions I’ve provided only short answers to encourage
further research. I have included only questions for mid (*) and senior
level (**) Java developers. These sample questions could also become handy
for people who need to interview Java developers (see also ... (more)
Yesterday, I made a trip to Manhattan on some family matters. While walking
by the the Seaport in the lower Manhattan, I noticed a group of asian guys
doing back massage to the tourists right on the street. I’m sure you saw
these special chairs where you kinda sitting on your knees while they work on
your back. Before, I never trusted my precious body to unknown people
unless they were licensed medical doctors or were working in SPA in luxury
hotels.
But about a week I started feeling some pain in the lower back somewhere
above the kidney. First, I thought it was a minor musse... (more)
