Time for a showdown.  In one corner we have the Pyramids of Giza…those ancient structures that have amazed, inspired, and enflamed the curiosity of millions throughout the centuries.  In the other corner is the burrito…that delicious meal of meat, bean, cheese (and various other tasty condiments) snuggled in a delicious encasement of tortilla.  One may think the Pyramid to be the favorite in such a showdown – a collosal monument, the last surviving Ancient Wonder of the World, the Titan of Tetrahedrons versus a glorified snack wrap?  Let’s watch the fight as it unfolds:

Round 1: Portability

Burrito is clearly the winner of this round.  While I am physically able to carry a number of concealed burritos on my person if I see fit (and I do), I don’t think I’ll be carrying a pyramid around anytime soon.  The burrito is testament to the very essence of portability.  Yes the picture seen here is an approximation of what it would look like if I decided to keep a burrito in the back pocket of my (apparently bedazzled) jeans.

Round 2: Halloween Costume Possibility

Round two ends up as a tie.  At first it seems as though burrito would take this round as well, until I saw this picture online.  While a burrito costume allows  you to make such amazing jokes as “Would you care to taste my spicy filling?” and “Dude, check out my costume – I’m a FUCKING BURRITO!”, the Pyramid costume allows you to bump into people ALL NIGHT, chalking your clumsiness up to the fact that you’re dressed as a large tetrahedron. SIDE NOTE: I’m not an expert but I’m pretty sure his use of MASSIVE AMOUNTS of masking tape is historically accurate.

Round 3: Visible From Space

A knockout round for the Pyramids – while not visible from the moon as some had previously speculated, they are visible in orbit which is pretty badass.  I mean, an extra-terrestrial whizzing by our planet wouldn’t think twice about burritos, but they might notice the Pyramids, and realize that there is intelligent life on our planet.   Even if the aliens then stopped by and ate some burritos (declaring them delicious, of course, in a series of clicks or otherwise alieny noises), they would have the Pyramids to thank for the resulting taste explosion.

Round 4: Creepy Embalmed Guy Stored Inside

OH MY GOD burrito wins.   One of the best things about burritos, in fact, is that they are refreshingly devoid of DEAD DUDES.  It may even be a good marketing idea to include that fact on EVERY BURRITO WRAPPER.

Round 5: Geometric Symmetry/Structural Integrity

Round five goes to the Pyramids.  It’s a no brainer – while the burrito is roughly cylindrical and unable to withstand any sort of rough or rapid movement without falling to pieces, the Pyramids are sublime exaltations to the tetrahedron, and have withstood millenia of abuse.

Round 6: Constructed by Slaves

It’s a well known fact that the Pyramids were constructed by slaves who were required to pull, lug, sweat and otherwise toil to the death under threat of whip.  Apparently, however, Chipotle isn’t too far off with the way they treat their tomato pickers, with the result being another tied round.

No post anterior falei um pouco de varargs, e como java escolhe quando tem dois ou mais métodos possíveis de se encaixar , sendo um deles varargs. O segredo foi que varargs sempre será escolhido por último.

Hoje, continuando a falar de escolha de métodos, tenho um novo problema. Digamos que vc tenha o seguinte código, já adianto que ele compila e roda.

O que aconteceu foi que as variáveis do tipo byte e short foram ampliadas para o método recebendo int. E a variável com float, foi ampliada para o método recebendo double. Primeiro ensinamento então foi sobre ampliação.

Agora abrir um parêntese rápido. Olha o seguinte exemplo parecido:

static void method1(Integer a){  System.out.println(“int”); }

static void method1(Long a){  System.out.println(“long”); }

static void method1(Double a){  System.out.println(“double”); }

public static void main(String[] args) {

byte x = 1;

short y = 2;

int z = 3;

float f = 4f;

method1(x); //erro de compilação

method1(y); //erro de compilação

method1(z);

method1(f); //erro de compilação

}

Os erros de compilação acontecem porque java não faz Ampliação e Autobox juntos.

Seguindo sobre prioridade em métodos. Digamos que temos dois métodos, um que temos um primitivo e outro seu wrapper correspondente. Qual a jvm escolherá? Ampliação ou Boxing?

static void method1(long a){  System.out.println(“long”); }

static void method1(Integer a){  System.out.println(“Integer”); }

public static void main(String[] args) {

int x = 1;

method1(x);

}

Saída será: “long”

Temos o segundo ensinamento. Entre Ampliação e Boxing, a jvm escolherá Ampliação.

Agora por último. E entre ampliação e vargs?

static void method1(long a){  System.out.println(“long”); }

static void method1(byte… a){  System.out.println(“byte…”); }

public static void main(String[] args) {

byte x = 1;

method1(x);

}

Saída será: “long” . De novo?hehe

Logo temos uma seqüência de prioridades: Ampliação > Autobox > Varargs

Regrinhas para decorar:

• se tratando de primitivos o método escolhido será o  de menor argumento possível
• não pode ampliar de um wrapper para outro
• não pode ampliar e depois boxing (Um int não pode se tornar um Long)
• é possível fazer boxing e depois ampliar. (Um int pode se tornar um Integer , e ser passado para um parâmetro do tipo Object)
• varargs pode ser combinado ampliação ou boxing

Agora só por curiosidade, a razão para ampliação ser o primeiro é simples. Autobox e Varargs são recursos que foram incorporados a partir da versão 5. Logo, como o lema do java é que atualize a jvm e continue com seu legado funcionando (sabemos que na prática não é bem assim, mas eles tentam),  os desenvolvedores tiveram que priorizar a ampliação, para que códigos legados continuem funcionando, e nada de esquisito aconteça.

Essas comparações são fichas certas no exame. É bom ficar com elas na cabeça .

Vargags é um assunto um tanto fácil quando se vê a primeira vez. E de fato é uma feature bem legal admito. Porém, como nada na vida é por acaso, existem umas regrinhas que precisam ser satisfeitas:

1.  Métodos que misturam outros parâmetros com varargs, o varargs deve sempre  ser o último parametro.

ex: void method1(int p1, long p2, String p3, int… p4)

2. Em decorrência da número 1, não pode haver mais de um varargs no mesmo método. Por razões óbvias, se houvesse mais de 1, um deles não seria o último!

3. A sintaxe é tipo + … . Cuidado pois é diferente de array que aceita colchetes ou antes ou depois.

ex:  void method1(Animal a …) //erro de compilação

Até aí regrinhas básicas. Agora vamos para parte interessante da coisa. Se tenho uma situação que o compilador tem que fazer uma escolha, qual critério? Por exemplo:

static void method1(int x, int y){

System.out.print(“1″);

}

static void method1(int a, int… x){

System.out.print(“2″);

}

Os dois métodos compilam sem menor problema. Se eu chamar:  method1(1,2); Qual o compilador escolherá?

Saída será : “1″, pelo simples fato que métodos com vargargs, serão sempre escolhidos por último. Fácil né? Mas, o exame vai usar isso para confundir, para quem já sabe é moleza… hehe

Depois de alguns meses estudando aos pouquinhos, está chegando o momento certo que eu marcarei a bendita prova da SCJP. Depois de ver muitas pegadinhas, vou ter que documentá-las para ficar preparado para prova. E talvez o melhor lugar seja aqui

Começando, falarei um pouco de Wrappers do Java. Não o básico, mas sim o que importa para o exame. Todos primitivos podem ser empacotados em seus respectivos Wrappers usando o autobox (feature do Java 5). Todo classe java por principio extende de Object, e logo tem seu método equals. No caso dos Wrappers não são diferentes, eles sobrescrevem equals, e retornam verdade caso sejam “significamente equivalentes”.

Ou seja,

Integer x = 1000;

Integer y = 1000;

System.out.print(x.equals(y) ) // Imprimirá true

Até aí muito fácil

Um pouco sobre o operador de comparação == . Esse operador retorna true quando usado em comparação de referências de objetos, ou seja, se duas váriaveis são atribuídas para o mesmo objeto.  Sendo assim,

Integer x = 1000;

Integer y = 1000;

System.out.print(x==y ) // Imprimirá false

Opa opa, muita calma nessa hora. Wrappers tentam reutilizar sempre a memória caso a mesma referência já tenha sido criada, assim como é feito com String literais. Só que tem uma condição para isso ser feito:

I’ve wrapped gifts with fabric before, but I never thought to do it like this!  And, it looks super duper easy.  Craziness.  Save on everything by using fabric you already have (be creative!). And, I suggest even including instructions on how to fold it…or at least the YouTube address (http://www.youtube.com/watch?v=Bn6zdyCAwJs)

This idea courtesty of http://craftingagreenworld.com/.

See it’s all about the chocolate this week! Cadburys want you to design a new Cadbury Dairy Milk wrapper with an Irish theme. The best five wrappers will go to a public vote on this website in January 2010. If everyone loves it you’ll win €10,000 and see your wrapper in shops across Ireland. If nobody loves it: you’re fired!

What you use to design your wrapper is up to you: draw it, paint it, stencil it, paste it, photograph it, stitch it, knit it or do it on a computer. It’s all up to you so the €10,000 is yours to win or lose.

There are three ways to enter:
1. Pick up a leaflet in your nearest store, cafe or college campus. Design your wrapper using the template on the back, then post it to: Cadbury Apprentice Promotion, 6 Ely Place, Dublin 2, or scan it and submit it below.
2. Download and print the template then post your design to the address above.
3. Design your wrapper in the Cadbury Studio and submit it on and submit it online.

Qt Designer is an important tool for designing and building graphical user interface from Qt components. However, if you are a Java programmer and want to use Qt Designer with Qt Jambi in Mac, you can’t simply double-click the Designer app bundle shipped with Qt Jambi SDK. If you do so, you can still invoke the Designer, but… with the C++ environments, it’s useless for Java programmers. Instead, if you want to use Qt Designer with Qt Jambi. You have to start the program from a `designer.sh` script placed in your Qt directory. It’s pretty annoying because you’ll need a Terminal to run this script until you turn it off. Also, it’s not intuitive.

So, I checked the script code and found what it does is simply to set some environment variables and then execute the Designer binary within the Designer app bundle. Therefore, I decided to make a “real” app bundle for the Qt Designer with Qt Jambi. It’s pretty easy to do this job by using Jump, one of my open source projects. Here’s the instructions.

1. Go to the `QTDIR/bin` directory in Finder.
2. Right-click the `Designer` app bundle, select `Show Package Contents`, and it will open a new Finder window.
3. In the new opened Finder window, go to the `Contents/MacOS` directory, then copy the `Designer` binary back to `QTDIR/bin`.
4. Now pick a location to start writing our wrapper. I simply make a directory called `designer` in my home directory, then open a Terminal and switch to it.
5. Back to the new opened Finder window, copy the `Contents/Resources/designer.icns` file to our new created `designer` directory.
6. Create a Python module named `designer.py` in `designer` directory, and its content looks like this:

   import os
   # Replace this path to your QTDIR
   qt_home = '/Users/olliwang/workspace/qtjambi-mac-lgpl-4.5.2_01'
   
   def main():
       os.environ['QTDIR'] = qt_home
       os.environ['DYLD_LIBRARY_PATH'] = os.path.join(qt_home, 'lib')
       os.environ['QT_PLUGIN_PATH'] = os.path.join(qt_home, 'plugins')
       os.environ['PATH'] = os.path.join(qt_home, 'bin')
   
       classpaths = []
       for filename in os.listdir(qt_home):
           if filename.endswith('.jar'):
               classpath = os.path.join(qt_home, filename)
               classpaths.append(classpath)
       os.environ['CLASSPATH'] = ':'.join(classpaths)
       os.system(os.path.join(qt_home, 'bin/Designer'))

7. Create a `config.jp` file with following content:

   dist_name = Designer
   main_entry_point = designer:main
   icns = designer.icns

8. Run `jump app` in your Terminal, and you’ll see a new created directory called `dist`, our new app bundle is in there.
9. Copy the created app bundle back to the `QTDIR/bin` directory, now double-click the `Designer` app bundle and everything should work fine. Cheers!

I use Python to write this wrapper for easy, you can of course do the same thing in Java. Just remember to modify the `main_entry_point` to the `Main Class` in config file.

Estas clases fueron diseñadas para poder envolver (wrap) los valores primitivos en objetos. De esta manera, los primitivos pueden realizar operaciones que se dan solo entre objetos, por ejemplo, agregarse a un objeto de tipo Collection.

Existe una Wrapper Class por cada valor primitivo en Java. La siguiente tabla enumera todas las Wrapper y sus valores primitivos asociados:

Todas las Wrapper Classes poseen dos constructores, uno que trae como argumento el valor del primitivo (i1) y otro que tiene como argumento un valor String del valor primitivo que se pretende envolver (i2).

Integer i1 = new Integer(42);

Integer i2 = new Integer(“42″);

En el caso de la clase Character, solo existe un proveedor y el mismo toma como argumento un objeto de tipo String

Character c1 = new Character(‘c’);

Los constructores para los objetos Boolean pueden tomar un valor booleano (true o false) o un valor String. Hay que tener en cuenta que cuando se construye un objeto Boolean pasandole como argumento un objeto String, el argumento es case-sensitive. Es decir, si nosotros pasamos como argumento

Boolean b1 = new Boolean(“True”);

El valor del objeto Boolean sera falso.

Desde Java 5, los objetos Boolean pueden ser evaluados en una expresion booleana:

Boolean b = new Boolean(“false”);

if(b) // si estamos usando Java 5 o superior este codigo compilara.

Esto es posible, ya que a partir de Java 5,  el compilador utiliza el ‘unboxing’ y permite que el objeto Boolean sea tratado como un valor booleano primitivo.

I’ve had a lot of discussions over the years about maduros and I’ve found many smokers have some misconceptions regarding these beauties. I am going to address some of those here.

The first item I want to discuss is strength versus the darkness of the wrapper. You cannot say with certainty that a cigar with a darker wrapper is stronger than a cigar with a lighter wrapper. For example, the Joya de Nicaragua Serie C is a strong cigar with a Connecticut wrapper. It is much stronger than the Torano Casa Torano Maduro, even though it has a nice dark wrapper. If you are a fan of stronger cigars, don’t limit yourself to dark wrapper cigars. Do the research and you will find others to try.

Secondly, the is a lot of confusion when discussing maduros- are we talking about a maduro color or the maduro process? There are about 50 color classifications to wrapper colors, usually reduced to six broad categories (thank goodness) presented below with all of their equivalent names:

• Double claro, candela, American Market Selection (AMS), jade
• Claro, natural
• Colorado claro, English Market Selection (EMS)
• Colorado
• Maduro, Spanish Market Selection (SMS)
• Oscuro, double maduro, maduro maduro, negro, black

Some of the cigars marketed as maduros are actually oscuros, or even colorado, when talking about color. Even worse is that a few manufacturers have added dyes to their cigars to make them nice and dark and labelled them as maduros. And technically, they are right- they are maduro in color.This practice was much more common in the cigar boom of the 90s, but I’m sad to say a couple of cigars at the last IPCPR show also had the dye treatment. I’m sure many of the retailers did not order them once they discovered the black stains on their mouths and fingertips. At least I hope so.

To get cigar wrappers dark naturally without dyes requires an intense and expensive fermentation process. “Maduro” translates to “ripe” in Spanish. As tobacco leaves are harvested from the fields, they are placed in curing barns for around 45 days. The leaves change from green to brown. For darker leaves, the tobacco is stacked in large piles called pillones. Heat is generated as the leaves ferment, and the pillones have to be rearranged from time to time to keep the all of the tobacco fermenting at the same rate and to inspect the progress. Leaves can spend several years (usually 3-5) in the pillones before they are finally ready. The fermentation brings out the natural sugars in the leaf causing the darkening color change. The longer this fermentation process goes the milder the wrapper becomes. The extra time and storage required for producing maduro wrapper is what leads to the maduro-wrapped versions of cigars being more expensive than their natural-wrapped counterparts.

There is another common way to create maduro wrapper. It is usually called “cooking.” It is really a steaming process where the wrapper leaf is placed in a steam chamber until the desired color is achieved. Obviously this is a quicker and cheaper method than the first method I described. The problem? It doesn’t really bring the sugars out like the natural process. The result is a maduro-colored wrapper without much of the maduro sweetness. These wrappers are usually used only on milder maduro cigars.

To do any of these methods, you must have a leaf that can take the intense process. You must use tobacco leaves that are particularly thick and hearty. Usually only leaves from the top two-thirds of the plant are used. The leaves near the top have more sugar, as the top leaves received more sunlight to fuel photosynthesis. The leaves at the top of the plant also produce more oils, which are used by the plant to help protect it from the sun. The stronger maduro wrappers are made from the top leaves of the plant, and the milder ones from the middle of the plant.

In part 2, I’ll discuss which tobacco varieties can handle this harsh process and how the region they are grown in affects their taste.

Working on a project, a requirement was for widgets to be placed on the main view. These widgets where required to be moveable and resizable.

In the past, I have used FlexLib’s MDI Canvas to accomplish this. In this instance however, I wanted to use pre existing components, and didn’t want to have to extend other classes.

My solutions was to create a wrapper for MXML for TitleWindows that would turn any container into bounds for the TitleWindows.

Here is the Widget Manager that I’ve come up with.

* Some clean up required.

Вот обернул ScrollBar в класс. Реализовывалось под свои нужды, поэтому работа ведется только со стандартными скроллбарами контролов(т.е. с вертикальным, горизонтальным или сразу с обоими). Выкладываю код:

class ScrollBar : Window
{
public:
	ScrollBar(HWND hParent)
	{
		_hParent = hParent;
	}

	void enableScrollBar(UINT wSBflags, UINT wArrows)
	{
		::EnableScrollBar(_hParent, wSBflags, wArrows);
	}

	void getScrollBarInfo(LONG idObject, PSCROLLBARINFO psbi)
	{
		::GetScrollBarInfo(_hParent, idObject, psbi);
	}

	void getScrollInfo(int fnBar, LPSCROLLINFO lpsi)
	{
		::GetScrollInfo(_hParent, fnBar, lpsi);
	}

	void scrollWindow(int dx, int dy, const RECT *prcScroll, UINT flags)
	{
		::ScrollWindowEx(_hParent, dx, dy, prcScroll, NULL, NULL, NULL, flags);
	}

	void setScrollInfo(int fnBar, LPCSCROLLINFO lpsi, BOOL fRedraw = TRUE)
	{
		::SetScrollInfo(_hParent, fnBar, lpsi, fRedraw);
	}

	void showScrollBar(int wBar, BOOL bShow = TRUE)
	{
		::ShowScrollBar(_hParent, wBar, bShow);
	}

	static WORD getScrollingReguest(WPARAM wParam)
	{
		return LOWORD(wParam);
	}

};

В принципе дополнить класс для работы со скроллбаром как с отдельным контролом не проблема, может быть как-нибудь займусь(что там заниматься: пару строчек дописать и все )

  We are nothing if not our associations. Constructs and connections, web of thoughts. A prime heron establishes itself on a prominent rock upstream of the overpass. Commanding attention, commanding a view. The rock upon which it stands is split-level and big enough to be a small island. Someone has left behind a candy wrapper, to sustain my existence. It is a BIG BOL wrapper, something you don’t see every day. SUPER is encircled or surrounded by an oval line. Combines with a crushed hickory hull – six pieces – that has a football shape. BIG BOL, super bowl, Notorius B.I.G., the rapper, BIG GLO, BIG BLO, BIG BLOW, fellatio or a crush. Crush proof box, New! BIG OIL, big oil producers. Big lob or a big glob. Bigeloil and Bigelow and a great big globe. Super. Super. Very BIG. GO. Pass go, collect 200 dollars and go outside and play.

This week, we have another guest review from our friend Danny Principe. Hope you enjoy!

I dont really know what else to say about this cigar other than it is absolute perfection. This is quite possibly my desert island cigar. I have been very lucky in my life. I have been able to sample the finest Cubans, some of the most elusive NCs, but this takes the cake. Very few cigars are of this caliber, though some do come to mind.

The Verdict:
Appearance: 14/15
Beautiful wrapper. No visible veins whatsoever, the only flaw was a slight hole in the wrapper. But this did not effect the enjoyment of the cigar whatsoever. Really the only flaw.

Flavor: 25/25
Unreal. Coffee, cocoa, at times leather, nuts, toast, some sweet cedar. Very typical Padron flavors, but so remarkably smooth that it really is hard to pinpoint anything standing out above the rest. Everything was in perfect harmony. The cigar was in the full bodied category, but it was just so smooth I did not seem to notice.

Construction: 25/25
Flawless. The cigar cut like a hot knife through butter. It lit up instantly, I used one match and it honestly lit up in 1/4 of a second and did not require a single bit of attention for the entire 3 hours I took to smoke this beauty. The draw was perfect. Like a razor the entire time. And every 80 Years I have smoked has been EXACTLY the same in this regard.

Overall Impression: 35/35
The price point is high, but I have to say, it is damn near worth it.

Final Score: 99/100

I know it seems a bit high, but if you have smoked one, and you love Padrons as much as I do, I am sure you will agree. Cant wait to see how the 45ths I just picked up do in comparison.

I always have trouble talking about 9/11—mostly because that day, for me, was defined by an abundance of emotion coupled with a scarcity of words. On a day when an entire nation was at a loss for words, there was nothing to do but feel, think and wonder.

For all its tragedy and somber, 9/11 was one of our generation’s most poignant events. Living through it moved our nation to redefine its identity and rediscover its pride. Experiencing it as a New Yorker moved me to fall in love with the city that’s always been my home all over again.

So, today, instead of awkwardly fumbling for words to commemorate all that was lost on 9/11, I’m celebrating a city that refused to let tragedy rob its spirit and virtue. Today, I’m eating for the Big Apple.

My Big Apple Breakfast:

I got the idea for fruit cereal from Katie at Yes, I Want Cake and couldn’t wait any longer to try it.

In my bowl:

• massive Ginger Crisp apple
• figs
• raisins
• slivered almonds
• ground flax
• cinnamon
• almond milk

I let it sit in the fridge for 5 minutes because I like my real cereal soggy—and figured the same preference would likely apply here.

Oh my god. Genius. The raisins and the figs were the perfect addition, and apples in almond milk? What an unlikely badass duo? This breakfast will be making frequent appearances.

I sort of wanted it again for lunch, but in an attempt avoid both monotony and physical transformation into a green apple, I went for this:

That’d be Jenny’s best wrapper alive, which I’d previously remixed. I used all the original’s components this time: tuna, garlic & herb LC, plain greek yogurt, diced apple and salt & pepper on a whole wheat wrap.

Lil’ Wayne’s got some competition because this is, indeed, the best wrapper alive. I loved my remix, but the apples really were the key ingredient. The wrap was  sort of overflowing—all the good ones do—but I managed to salvage any of its lost innards. Si, by that I do mean that I licked the plate.

Ok, I’m off to jumpstart my weekend (yes, weekends are still weekends when you’re unemployed because that’s when your employed friends come out to play!). I hope all your weekends are fun and food-filled!

T.G.I.F. (I wish Sabrina was still on),

When working on different projects, you have to use time-consuming mysql commands every now and then. Same was the case with me and i had really got sick of all those commands, so i decided to create my own mysql wrapper with ability to perform the similar tasks far more quickly and easily than their mysql counterparts. I have used it in many projects i have developed and it has saved me about 50% of the time as compared to using mysql default functions.

You can download the file whole class with example here.

.

.

So here is the code for the sample file, name it quickdb_example.php

	// Online Class Location:
	// http://www.phpclasses.org/browse/package/5318.html

	/*

	In order to use the example here, you need to create a table,
	just execute the following SQL lines using your MySQL client:
	-------------------------------------------------------------

	################################
	CREATE TABLE `quickdbtest` (
	  `catid` int(11) NOT NULL auto_increment,
	  `catname` varchar(255) default NULL,
	  PRIMARY KEY  (`catid`)
	);
	insert  into `quickdbtest`(`catid`,`catname`) values (1,'Big'),(2,'Small'),(3,'Average'),(4,'Light'),(5,'Huge');
	################################

	*/

	// This file uses most of the functions of QuickDB MySQL wrapper.
	// It is very easy to use these funtions (methods), see below examples.
	// Once you know how to use this, i bet you are gonna use it in future as well  

	require_once "quickdb.class.php";

	// it can run any query whether select, insert, update or delete like mysql_query function

	// returns:
	// 1) resource identifier for "Select query" that can later be used with mysql_fetch_array or mysql_fetch_object
	// 2) number of rows affected for "insert, update or delete" queries
