When I was a child I heard some advices that were written by one Brit to his son( I don’t know who exactly, I’m even not sure that he was Brit, but I believe he was… doesn’t metter ). I heard it on the radio and found them rather intelligent,  wise, rather laconic and easy to undestand so somehow I keep them in my mind, at least some of them.

Time flows. Now I’m a father and feel like giving the list of this advices to my son. It was a bit difficult to find them but here they are:

• Sing in the shower
• Treat everyone the way you want them to treat you
• Plant flowers in the spring
• Leave everything a little better than it was before you
• Never gave up home-made pastries
• Strive for excellence, not perfect
• Look people in the eye
• Do not wait, that life will be fair
• Learn the three decent jokes
• Return debts on time
• Make a compliment at least three people every day
• Ask a supplement if you feel that you deserve it
• Encourage others to even the smallest improvement
• Never underestimate the power of love
• Smile
• Think about the big and enjoy small
• Do not be afraid to say “I made a mistake”
• Do not forget old friends
• Be very optimistic and enthusiastic of all the people you know
• Have some champagne just so, without reason
• The first to say hello when meeting
• Be where you need
• Stop blaming others
• Always shook the outstretched hand
• Farewell to themselves and others
• Often say “Thank you”
• Often say “Please”
• Wear shoes peeled
• Never missed an opportunity to tell someone that you love him
• Remember the birthdays of other people
• Live as an exclamation, not as a justification

• Take responsibility for every day of my life
• Be committed to continuous improvement
• Sing a chorus
• Plant a tree in her Birthday
• Head of a dog
• To marry only for love

As far as web browsers are concerned, everybody knows that Microsoft IE sucks. It is the slowest one, lacks Web Standards, makes webdevelopers work long hours fixing IE issues.

But here are the Good news -> Google brings power of upcoming HTML5 to Microsoft IE and boosts IE’s JavaScript performance ->

IE8 runs 10 times faster with Google plug-in
Chrome Frame instantly boosts Microsoft browser’s JavaScript performance

here is a developers guide how to force IE using Google Chrome Frame on your sites.

SunSpider benchmark results show IE8 with the Chrome Frame plug-in is nearly 10 times faster at rendering JavaScript than IE8 alone.

Today deploying my rails application on FreeBSD server with just installed RoR I ‘ve got some completely unexpected errors.

>$ruby script/console

>Loading development environment (Rails 2.3.2)

>/usr/local/lib/ruby/gems/1.8/gems/activerecord-2.3.2/lib/active_record/i18n_interpolation_deprecation.rb:23:NoMethodError: undefined method `alias_method_chain’ for I18n::Backend::Simple:Class

Googleing shows that many people gets in the same trouble  - nonworking fresh install of rails on FreeBSD ( probably this problem belongs to other BSD or Linux). (http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/342f99c546440fff/559e5fa694476b0c?lnk=raot)

So if you see this error when trying to execute `rails` command:

>$rails helloappl

>undefined method camelize for app:String

Don’t panic. Everyting ok and  solution is pretty simple. In fact its not a trouble with rails, but  there is a missed unmentioned dependency

all you need to do:

>$cd /usr/ports/converters/ruby-iconv

>$make install clean

Hope this post will help somebody to don’t waste time on sort out the problem.

The goal was to make online calculator that will produce the same results calculations that there was alredy made in  spreadsheet. 

First of all I thought How I do that. It looked quite hard to code all non-transparent logic and data with different formulas that was already done  in xls file that I’ve got from my custumer. But what if just open xls(odf) file change some cells value (input  params )  and read the the result of calculations from others. This thought had crossed my mind. There sould be tools that could work with .xls or .odf files and I need a crossplatform one.  And I start looking up….

Talking about Advanced JavaScript debugging.

First of all about tools. Currently, the most powerful debuggers are the Firebug extension in Firefox and the Opera Dragonfly debugger in Opera.
Firebug is well-known, userfriendly, and its more than enough in most situation. But from my own expierence, sometimes Dragonfly can help to debug code that has been “packed” and needs to be unpacked using eval(), when Firebug can’t. I was faced with such situation about half a year ago when I need to fix an application based on Dojo.

Now about techniques. Here is an particular interesting technique that I found from the article “Advanced debugging with JavaScript” :

…Debuggers for many other programming languages have a “watch” concept that can break into the debugger when a variable changes. Neither Dragonfly nor Firebug currently support “watch” but it’s easy to get the same effect by adding the following line of debugging code at the top of the source of the script you’re troubleshooting:
__defineSetter__('prop', function() { debugger; });
Using getters and setters can emulate “watch” functionality and help you set “smart” breakpoints.

A good news jQuery 1.3. released on January 14,2009. There are quit many changes and improvments. 

These three are very important as for me:

Two month ago I build Glassfish v.2 on my FreeBSD 7.1/i386 . It still works. And no failures.

So here is my expierence. It was based on this articles Building GlassFish on FreeBSD and Compile Glassfish on FreeBSD (JDK 1.5)  (which are primary the same) and some others.

First of all:

1) Don’t try to build it using maven2 . Just use maven (/usr/ports/devel/maven)

2) It ‘s important to specify which BRANCH to checkout cause if you don’t you ‘ll get the newest sources that won’t be compiled.  To Checkout sources of Glassfish v2 use:

 $cvs -d :pserver:YOUR_ACCOUNT_LOGIN@cvs.dev.java.net:/cvs co -r SJSAS91_UR2_BRANCH glassfish/bootstrap

3) Don’t try to build it using jdk1.6 cause you get build errors on step 4 ‘Build the checked out source code. ‘

That’s all. Step by step tutorial you find in  Building GlassFish on FreeBSD just remember my remarks.

Nice arrow in night Sky …

There was no good documentaion but in fact was realy easy.
1) get sources rfunc-2.1.3.1-RC1-unix.tar.gz
2) untar it:  

#tar -xzf rfunc-2.1.3.1-RC1-unix.tar.g 
#cd sources

3)change config file ‘makefile.freebsd’: here is my config makefile
4) run make :

#make -f makefile.freebsd rfunc

5)copy ‘rfunc’ to ‘/usr/local/libexec/firebird/udf/rfunc.so’

#cp rfunc /usr/local/libexec/firebird/udf/rfunc.so
