blogging from an iphone

It's not very easy, this is the first phone that is sophisticated enough to support the editing page and easy enough to be usable for that purpose. Uploading does not work. Rich editing does not work. But typing is fast enough and easy enough.

Hibernate, AuditLogging, cannot configure listeners in persistence.xml

First, what's my goal
I want to do an audit log. I read the http://www.hibernate.org/318.html and there two different approaches were mentioned.
The first is using a Listener.
The second is using the new eventing model in Hibernate3.
The author said that he couldn't make the eventing approach work for an unknown reason.

I'm using Hibernate via JPA. I'm using it in an EJB. So the problem with the first approach is that it is difficult (if possilbe) to supply the same transaction to the interceptor so that it can write an entry in the audit log. There is a solution with a static field holding a session or an EM, but that seems ugly.

So I chose the second approach. I created a class, inherited few eventhandlers (PreInsertEventListener, PostUpdateEventListener ) and tried to add the class as a listener.

Using the API, it worked (the callback methods in the listeners were called):

AnnotationConfiguration configuration = new AnnotationConfiguration();

configuration.setListener( "post-update", new Test1() );


configuration.addProperties( hibernateProperties );
EntityManagerFactory factory = new EntityManagerFactoryImpl( configuration.buildSessionFactory(),
   PersistenceUnitTransactionType.RESOURCE_LOCAL, true );
EntityManager result = factory.createEntityManager();


Using properties (as if using persistence.xml) failed(the callback methods in the listeners were NOT called):

Properties hibernateProperties = new Properties();
...

hibernateProperties.put( "hibernate.ejb.event.pre-update", "package.Test1" );
hibernateProperties.put( "hibernate.ejb.event.pre-insert", "package.Test1" );
 
AnnotationConfiguration configuration = new AnnotationConfiguration();
configuration.addProperties( hibernateProperties );
EntityManagerFactory factory = new EntityManagerFactoryImpl( configuration.buildSessionFactory(),
   PersistenceUnitTransactionType.RESOURCE_LOCAL, true );
EntityManager result = factory.createEntityManager();


Ideas why?

A new challenge - a dog

I have to keep it alive for 24 hours. It's gonna be hard




Update: It's done - I successfully returned the dog alive, unharmed and in good condition.

Category A in my driving license

Today I passed the exam for category A (motorcycles above 50cc). Very happy.

'Sucks' category

There's a trend - there are a lot of articles here in which I bitch about something. So there should be a category called 'Sucks'.

Update: reviewing the articles I found a lot of candidates for the category, it comes out that all I'm doing is bitching about stuff - I should change the subtitle of the blog :)

@Override in eclipse

When one implements an interface, the template in Eclipse puts an @Override and it does not complain about it. Ant javac task also compiles without warnings.

Sometimes other Eclipse instances start to complain exactly for that @Override stating that there's no method that's overridden. Well, Eclipse, please do make up your mind.

http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Override.html
"Indicates that a method declaration is intended to override a method declaration in a superclass. If a method is annotated with this annotation type but does not override a superclass method, compilers are required to generate an error message."

Well, that's not very clear. As far as I remember an Interface is a pure abstract class, right? So, which one's correct.

P.S. Sometime ago I was having a similar problem with Eclipse and generics - Eclipse only gave a warning about something (can't remember what exactly), but the javac said that it was an error - Google said something like "eclipse uses jikes, you use javac". So what, aren't there specs?!

Referrers from live.com

All the referrers to this blog from live.com come like that:
http://search.live.com/results.aspx?q=class&form=QBHP or
http://search.live.com/results.aspx?q=interface&form=QBHP

The search word seems to be only 'class'. I can't believe that I come out in a search for only the word 'class'. I guess all the other words from the search are stripped which, if on purpose, is stupid, and, if not, ignorant.

Разговор за софтуера и бизнеса в него, дори за бизнеса като цяло

Той: em toq html nema izmestvane 100 godini veche

Той: mn tapo

Той:  It can make direct calls to JavaAPIs that are on the platform.

Той: e to pochva da prilicha na aplet ;)

Аз: всичките технологии са аплет-like

Аз: виж кой им е предшественика

Той: da samo ne znam kak opredelqt thin / fat client

Той: to sa razmiva leko

Той: ajax-a e thin i toi uj ;)

Аз: има група хора (аз също съм от тях), които са свикнали да пишат на силно типизирани езици и име е адски трудно да разберат как технологии като perl, php, rss, html, javascript и разни други 'боклуци' придобиват такава голяма популярност - отговорът е в леснотата на употреба и бързината на разработка. А че се жертват разни неща като добър стил и loose coupling - на кой му пука

 Той: awe za html i www kvo mu e lesnotata chovek

 Той: kat v ie raboti po edin nachin u firefox ne

 Той: i staash na lud

 Той: tva e nai-golemiq tashak :)

 Той: prosto ne moa da povervam che sa go dopusnali

 Той: ako imashe pone malko tipizirane :)

 Аз: There is a certain group of people (counting me too) that are used to working with strongly typed languages. It's really hard for that group of people to understand how technologies like php, html, javascript (..., rss, perl, ...) become so popular.

 

The answer is (in my humble opinion) the ease of use and rapidness. Everybody can learn to use them. Sacrificing the good style and the heavy approach (that comes from the heavy books) comes out be (in most cases) an acceptable loss.

Аз: последното изречение го прочети няколко пъти

Аз: :)

Той: :)

Той: awe tva jnlo mn bavno zarejda obache

Той: https://openjfx.dev.java.net/learning.html

Той: skivai tova

Той: http://download.java.net/general/openjfx/demos/tesla.jnlp

Той: ima torque/power curve

Той: a to html i js uj prosto ama vari pravi ajax

Аз: ?

Аз: винаги съм се дразнил на джава приложенията, че нямат райт клик

Той: mi ne e prosto da praish dobar interface (ajax) za www

Той: ich daje

Той: kav right click :)

Аз: explain:

Аз: a to html i js uj prosto ama vari pravi ajax

Аз: mi ne e prosto da praish dobar interface (ajax) za www

 Аз: apletite i сега javaFX нямат right-click

 Той: nali vikash che sa razprostranilo shot bilo prosto

 Аз: zabranen e

 Той: :)

 Аз: da, taka e

 Той: em prosto da praish prosti neshta :)

 Аз: taka :)

 Аз: гмаил, гугъл мапс

 Той: zashto tezi koito iskat da praat ne prosti neshta tria da lejat varhu prosti tech

 Аз: прости ли са?

 Той: shot prostite tech sa sa nalojili

 Аз: защото те са популярни и се поддържат от публиката

 Той: ili shot te samite sa prosti che ne sa nalojili drugo vmesto da praat shitove running varhu prostite tech

 Аз: бизнесът търси размах, дори и да имаш супер технология, ако тя не се ползва, няма смисъл от нея

 Той: mrazq bisnes :)

 Той: i mrazq da mrazq :)

 Аз: трудно е един бизнес да 'налага' технологии (виж на Майкрософт колко им е трудно един стандарт да наложат)

 Той: mi to ako e qko moje da se samonaloji sigurno

 Аз: целият софтуер, който се пише е подчинен на основни бизнес зависимости: (микроикономика 101) търсене и предлагане

 Аз: има доста адекватни технологии, които не са се наложили

 Аз: причини много ()

 Аз: една технология, за да се наложи и трябва много повече от техническа адекватност

 Аз: там отново се намесва мразения от теб бизнес

 Аз: :)

 Той: biznesa razvalq sichko

 Той: vnasq mn izkrivqvane

 Той: ne sa prai shot e qko a shot tekat pari

 Той: i vsichko e shit

 Аз: приятелю мой, забавно е да те слуша човек

 Аз: причината е в развитието

 Аз: смята се, че пазарната икономика води до най-високо развитие. Тя се гради точно тоя принцип с парите, търсенето и предлагането и конкуренцията

 Той: pazarnata ikonomika e shit :)

 Той: vij posokata na razvitieto obache

 Той: tva e edna dosta shibana posoka

 Аз: посоката?

 Той: izkrivena ot bisnesa

 Аз: бъди по-точен

 Той: shit ot sekade :)

 Той: posokata da se pechalat pari

 Аз: разбира се

 Той: razvitie saobrazno taq posoka

 Той: tva e shit

 Той: pitai malkite deca ako ne mi vqrvash :)

 Аз: това е най-важния (ако не единствен) показател колко добре се справяш - универсалният показател

 Аз: хаха

 Аз: кефиш

 Той: toq pokazatel vaji samo taq matrica :)

 Той: v

 Той: v taq

 Аз: така е

 Той: :)

 Аз: другите опитани модели са плановата икономика (комунизмът), която практиката показва, че е не толкова успешна

 Аз: Пазарната икономика е естествен механизъм, който те принуждава да оптимизираш ресурсите, с които разполагаш

 Аз: парите са просто универсално разменно средство, нищо повече

 Аз: :)

 Той: mn poveche ot tova sa :)

 Той: vsashnost

 Той: za neshtastie :)

 Той: ne che i na men ne mi triat ama ..

 Аз: какво друго са?

 Той: te promenqt horata we

 Той: ne samo nekvi hartiiki

 Аз: хаха

 Аз: не перите ги променят, жаждата за материалното ги променя

 Той: e to e sashtoto :)

 Аз: а то, материалното, се измерва с пари просто

 Аз: но не забравяй, че тази жажда (или алчност ако щеш) кара същите тези хора да се стремят към тях и да работят

 Аз: двигателят на прогреса

 Аз: точно тук е гениалността на пазарната икономика естественото желание да купиш най-много с най-малко

 Той: na metrialniq progres

 Аз: ?

 Той: materialniq progres

 Аз: ами духовното е индивидуално, много трудно се измерва с пари и е трудно да се вкара в тая 'матрица'

 Той: to ne moish da go izmervash s pari

 Той: am kvo stana s html i js

 Той: shte gi mahame li ot upotreba :)

 Аз: едва ли скоро

 Аз: :)

 Аз: бтв, мога ли да пусна разговора в блога си?

Strongly-typed vs. weakly-typed

There is a certain group of people (counting me too) that are used to working with strongly typed languages. It's really hard for that group of people to understand how technologies like php, html, javascript (..., rss, perl, ...) become so popular.

The answer is (in my humble opinion) the ease of use and rapidness. Everybody can learn to use them. Sacrificing the good style and the heavy approach (that comes from the heavy books) comes out be (in most cases) an acceptable loss.

Chill the coffee out

Patents pending - don't steal my intellectual (he he) property.

The biggest screen resolution I have ever seen - found in my living room

Have you ever seen a screen that supports that big a resolution? This is (...calculating...) ~4.29 GigaPixels. Quite a lot, huh?

Check out how many options it gave for color depth.



P.S. This happened on a friend's machine after two years of no support and windows update.

README - gramatic rules for the Bulgarian language (priceless).

Although it's short and incomplete it's really a cornerstone read. Every single Bulgarian must be forced to read it and memorize it:
http://www.uni-bonn.de/~manfear/lang_mistakes_bg.php

In a few days

In a few days this adventure (having a blog) is going to have its first birthday. I remember the birthday because it is embedded in the admin password (yea, try me ;).

Today I was reading a few articles about having a blog (here and here) and the impression I got left with was that starting a blog is not always a good idea and to do that you have to have something to share and to follow some rules and most importantly have a goal.

F**k that. (Update: I don't know why I put asterisks, maybe I'm afraid of the moderators ?!)

I don't know if I have something to share. I don't know if I have a goal set for my blog. I didn't know about the rules until today. But I don't care.

What made me start the blog was an article from Joel (I can't find it right now) that simply said that a blog can help you express yourself better, can help you perfect the language you present your blog in, can help you understand yourself better. And one other thing - get more feedback for yourself - and that one is particularly precious for me.

So, do I follow the rules - no. Do I care - I guess not. (yea, sometimes I check the logs to see how 'famous' am I and the good results and some comments boost my ego, but that's pretty much it). Overall, I find it a good experience and the time spent on the blog wasn't completely waisted.

What am I going to do from now on - I guess pretty much the same thing.

P.S. Thank you my one reader for the continuing support and the few comments you left from different IPs (appreciate the effort). I would gladly buy you a beer.


'I'm shocked'

'I'm shocked' is what Charlie Sheen playing Charlie from 'Two men and a half' always says with a beer in his hand when his brother does something stupid.
(Comment to me: I have a problem: cannot produce short sentences.)

Here I am playing the dumb thing Vasko and I gave as a present to one crazy dude:



Update: it's fu*king unpleasant.

the telephone of confidence

Last night I fell into depression, and called "the telephone of confidence".
My call is redirected to Pakistan.
I said that I'm going to suicide.
They rejoiced and asked me if I can drive heavy trucks ...
