New Incomes for My Head

2011-08-21T12:23:00.006+03:00

It was a time, when I didn't know a lot of stuff from Software Development. But almost 5 years ago, I started work as PHP developer on @Softjourn company. And day by day I had a chance to improve myself in IT sphere. This year I've started work as JAVA-developer, and it was big chalangeble java-related-year for me.

Considering new incomes for my JAVA oriented head, not exception is recent event - itBooze Meetup #3 organized by local (Ivano-Frankivsk) group @IT_Booze and personally by @grishaster and @halyph who are from @SoftServe IT company.

This meetup was dedicated to "code quality tools" ...

So, first of all, as I always say to myself - "Any other experience can be useful for me me later", on this meetup, I had a chance to listen about other area of IT, like Pex, Groovy, Ruby, etc. And it was great. Why? Because, now I have new ideas how to improve myself and what the best practices has IT community, and I can use it for my Projects.
For example, I want to use 100% code coverage in Java like it is with using Pex. Hope for Java must be the same tools. I want to find find smart tools which will help me develop good code.

New for me is discovering of Sonar server, from Lena (@LenaDSS) speech in scope of Flex. Hope I will have a time to use it on/with Java projects.

Yes, I already use PMD and FindBugs, and they are awesome. New for me was CodePro Analytix which I will try to use on my current java project.

As well as java based, new for me was CodeNarc which works better i think with Groovy projects. And as @grishaster assured all of us, it can be used with Java project. This i want to to try in nearest future.

All of that stuff, I will try to use with My Eclipse IDE as well as stand alone, and hope it will increase quality of my code.

Thanks to all reporters for his work. Good Job :)

PS1. There was mentioned a lot of Tools by @halyph and other in their presentations, and hope all resources will be posted soon on official site of ItBooze.Com.Ua or in Other social networks (VK, FB)

PS2. Regarding next meetups, would be great to hear some kind of news about:

ESB frameworks experiense (GlasfishESB, JBossESB, Oracle ESB, other X-ESB ) and maybe work with XSD-to-JAVA generation with JAXB or another stuff.
Or other possible way how to develop interesting projects almost without coding, using UML, XSD/JAVA mapping or other not known for me ways.
Another topic to discuss would be great to see a battle of Spring/Struts/JSF and other related frameworks. Cause there are a lot of them, and as for me - I want to choose the best one, and use for future (Currently I am using Spring, but still want to be informed about other competitors)
I know there a lot of Java-based frameworks which can generate as final result javascript. AFAIK it is GWT and similar. Recently, I was involved in java-javascript-spring-struts-ejb-hibernate project and there was a huge weakness - simple javascript coding, and I hated this so much. So would be great to hear about Java community experience in development Good Javascript functionality, which will follow MVC and can be very salable in future. Would be great to hear some comparison about existed Javascript-mvc-based frameworks like ExtJS or similar. Or something in this area.
One more as for me (because I am Zero in Groovy/Ruby) to hear about some projects which was migrated from Java to Groovy or another migrated projects. Actually I want to figure out on real projects all benefits of these "X-y" languages.
'Which is the best build tool?' Maven vs Ant vs Gradle - not only comparison table, but how migration was and what exact benefits all of them can give for developers and for entire product in scope of scalability and usability.

PS3. Another resources about Code Quality from Web

WTF Code :

Code Quality! Building code you won’t curse tomorrow :

A high quality product will lead to stronger customer and developer binding.

No substitute for understanding :

Here’s how I conceptualize it. A software development novice — a manager perhaps — hears about “code quality” and that “design” is used to produce it. Design costs money and code quality helps developers write features faster.

MultiSite & MultiGroup system

2010-10-28T19:17:00.011+03:00

There a few viable off the shelf options to use:

Domain Access, Drupal Multi-Site, Spaces and Organic Groups and Development Seed Aegir or Open Atrium.

Drupalers - What is the best way to develop MultiSite platform?

Requirements for Multi-Site would be:

* Ease of use of upgrading and sharing one code base, each site will share core functionality - update once for all sites,

* Can NOT affect performance and scalability -- as we grow into the 100's and 1000's of sites we will need an easy way to deploy these sites across multiple systems for performance reasons,

* Very easy and quick way or rolling out new organization websites as they sign up,

* Sites will not share permissions between users on different sites,

* Single sign-on is not a requirement between sites (no need),

* There will be a need to share common blocks with each site that are controlled by the MainSite admin person (i.e. Me) -- For example a common block for an ubercart store and a common block to display advertising,

* Websites can vary drastically in information architecture and user interface, with similar core functionality,

* allowing an Ubercart store to span multiple domains, storing the originating domain when an order is made and displaying the correct store information on invoices,

* each site can be configured to use a different theme and look and feel,

* each site will have its own url.

* allow for secure transactions (https)

The main, dream - is th have one magic button - to deploy (roll-out) any new sub-site, but I can't imagine this now...

Help me ...

Так вот ... есть такие варианты развертывания мультисайт платформы:

Domain Access
Spaces
Organic Groups
Development Seed Aegir or Open Atrium.

и хочу собрать сравнительный анализ адвантежес и недостатков этих все варианотов.
Есть даже спецификация, точнее требования для сайта, или каков он должен быть:

* Прост в использовании главной функциональности сайта (one code base). Апдейт сайт главного должен быть использован и на саб-сайтах, автоматически

* простой метод создания сайтов для новых организаций, груп. нужно простую систему деплоймента, точнее создания новых сайтов

* Так как планируэтся использоватьь 100-1000 под-сайтов, хотелось бы что их количество не влияло на глобальный перфоменс (работоспособность главного и под сайтов).

* нет надобности делится с правами на уровне пользователей между всемя сайтами.

* нет надобности в совмесной (одновременной) регистрации/аутентификации.

* но есть надобность делится блоками между сайтами, которые контролируются главным сайтом. Для примера общий блок "ubercart store" и advertising (реклама)

* разрешить Ubercart store покривать мульти домены. это нужно использовать в процесе генерирования ордеров. (нужно только хотя бы узнять - может ли Уберкарт работать по мульти саб доменах)

* сайты могут радикально отличатся внешним дизайном, а также информационной структуры, но в рамках одной и той же code base.

* каждий сайт может иметь как общую так и собственную тему.

* как уже истекает из вище сказаного - own url - свой веб адресс.

* вожможность производить защищенные операци (https) как просто на сайте так и через Ubercart

главная мечта - иметь "одну кнопку" для развертывания новых будь каких сайтов.
В Aegir там есть такой контетнт тайп "Site" => "Create Content/Create Site"
Это конешно не кнопка, но через UI .

Так что - хочу выбрать лутчее мултисайт решение, что бы имплементировать все требования клиента.

PermGen space - How To Fix ?

2010-07-15T13:19:00.005+03:00

Short steps to do it.

"How to fix it?"
- Tomcat – java.lang.OutOfMemoryError: PermGen space (переглянути на Google Sidewiki)

Plus here we can find:

"Explaining java.lang.OutOfMemoryError: PermGen space" - how to monitor Memory usage

And here we can read more about OutOfMemory and other Memory ERROR MESSAGES fixing

java.lang.OutOfMemoryError: PermGen space

If you get the error message: java.lang.OutOfMemoryError: PermGen space this means that you have exceeded Java's default 64Mb block for loading class files. This can happen if many plugins are installed. You may want to increase the PermGen memory size to suit your needs.
In the following sample, the blue parameter shows how the PermGen Memory has been set to 192 megabytes. This value should be set depending on your memory requirements. 192m should be sufficient for Confluence even when many plugins are installed.

JAVA_OPTS="-Xms128m -Xmx1024m -XX:MaxPermSize=192m $JAVA_OPTS -Djava.awt.headless=true "

Note: The other parameters in this sample are just shown to give you some context, and are not part of this example.

java.lang.OutOfMemoryError: Java Heap Space

Heap space memory errors occur when the application has to deal with large amounts of data or users. These errors will contain only a java.lang.OutOfMemoryError, e.g. without the reference to PermGen space as above. You should try to increase the heap size to solve this problem. This requires configuring the Xmx and Xms parameters. In the following example, the maximum heap size is set to 1024 megabytes. This should be enough for small to medium deployments.

JAVA_OPTS="-Xms128m -Xmx1024m -XX:MaxPermSize=256m $JAVA_OPTS -Djava.awt.headless=true "

Note: The other parameters are only shown to give you context and are not part of this example.

Deployments with high usage patterns may require additional memory. For high-usage deployments, it is recommended to set both Xms and Xmx as the same value (eg. -Xms1024m -Xmx1024m), provided the memory is available. On the other hand, adding too much memory can also cause problems (see below), so you should increment memory carefully, for example in increments of 128 megabytes.

There's been a lot of talk of lately about the 'new' Cross Site Request Forgery (CSRF) vulnerabilities that are apparently present in nearly every web application in the world. The fact that big name websites (read: yahoo & google) have this vulnerability make people even more scared."

The requirements for a successful XSS exploit requires the following:
1. XSS vulnerability existing on the application (preferably before login).
2. A method to induce the execution of a script (eg. phishing email).
3. An effective script to steal user information.

The requirements for a CSRF exploit are in fact more stringent:
1. A form that is vulnerable to CSRF.
2. A method to induce execution of the request.
3. A successful form submission method.
4. A vulnerable form that provides an attacker with a useful attack vector.
5. Access to the form (since forms often exist after login).

Drupal Camp 2010 (Kyiv)

2010-06-14T12:41:00.001+03:00

Отож Кемп відбувся, час пройшов, інформація в голові поки що не систематизована, тому треба братись за систематизацію.

Загалом для мене вийшло навіть дуже не погано.
А саме:
10 червня, я все таки приїхав до Києва, хоча там і був нульовий день кемпа, я найшов чим занятись.
Власне пішов по капец жаркому Києву глянути як живе Дарницький район (там в мене був готель)
Тут можна побачити фото Києва

11 червня почався 1 день кемпу - Як завжди реєстрація, зустріч з старими друзями, знайомство з новими друзями, ну і звичайно потік Друпал-інформації :)
Ось власне пару фото з 1 дня.
Виступив я з доповіддю про Друпалівські ДТП... - хоча власне вже на початку доповіді зрозумів що тема була вибрана не дуже вдало.
Це ж програмісти всі - їм треба точні дані, а не розмиті теми з глубоким підтекстом...
На майбутнє врахую.

А тут перша частина доповідей з кемпу.

Приємно вразило те що було після закриття 1 дня - AFTERPARTY :)
Тут (а також поряд з цим тут є ще пару тут :)) можна глянути відео мастерінга від DJ, а також можна глянути пару фото захватів тут
Ладно вговорили ...

12 червня відбувся 2-й день кемпа. Власне я очікував більше народу, і пришов швидше ніж початок реєстрації, адеж я думав що ентузіазму буде більше ніж того року.
Фото з Дня 2-го

Також є відео виступу @BrunIF про Drush модуль і з чим його їсти. Але воно важить 700м, і хз коли я його викладу в нет.

Відносно місця проведення.
Давно хотів попасти на МВЦ, адеж тут багато ДЖїв проводять свої виступи.. І цього разу не виняток.

DJ Paul van Dyk, International Exhibition Centre (Brovarsky 15), 12 June at 19.00

Прикольно, споглядати як відбувається процес підготовки залу та сцени
Ось пару фото та відео

І саме головне що всі так довго чекали... - DRUPAL.UA
Я очікував більш офіціозно та пафосно.. але приємно вразила мене простота і "невинність" цього процесу... раз два і всьо :)

Ось лінк з твітера, його вже напевно всі передивились.. але все ж таки...

Отже....

Хочу виразити подяку організаторам кемпу, особливо @neochief (@ShvetsGroup) та @podarok
Слід відзначити всіх спонсорів, список яких є на сайті кемпу. :)
Хіба що окремо виділю SWB, головним представником якої є @maximzelevski наш франківчанин, який бороздить терени ІТ-сфери в Києві :)

Як завжди результативна поїздка до Києва принесла багато вражень та нових думок в житті пересічного програміста-ітшніка :)

Живемо далі.. чекаємо наступних івентів та різноманітних перфоменсів.

Щоб багато не писати.... Ті хто знають ті знають, а інші гляньте сюди:
Chernivtsi InTouch

Враження як завжди позитивні - нового не багато, але якісно.
Гарна і успішна організація, а особливо місце проведення - Чернівецький універ в архітектурному дуже гарному стилі.
В Твітері люди писали свої думки:
#cvintouch
А також якщо була можливість переказували що відбувалось в двох залах, адже не всі могли попасти на всі перзентації, тому твітер допомагав зорієнтуватись. Не скажу що було дуже інформативно, але в любий момент можна було перейти з залу в зал, і глянути що ж там діється.

Фотокусочки я поки що розмістив тільки тут(Picasa)

< load-on-startup > 1 < /load-on-startup >

2010-04-19T17:46:00.000+03:00

This is very important to XML validation where to put this code:

< load-on-startup > 1 < /load-on-startup >

in web.xml during Java/Spring development.

More infor will be later.

This is bad when we have :
Cause we have XML validation warring:
Checking file:/...../web/WEB-INF/web.xml...
cvc-complex-type.2.4.a: Invalid content was found starting with element 'init-param'. One of '{"http://java.sun.com/xml/ns/j2ee":run-as, "http://java.sun.com/xml/ns/j2ee":security-role-ref}' is expected.

And this is bad markup:



spring-ws
org.springframework.ws.transport.http.MessageDispatcherServlet
       1 


transformWsdlLocationstrue

This is good:

spring-ws
