Japan Creates Worlds Fastest Supercomputer

Senin, 24 Maret 2014

When it comes to the most powerful supercomputers in the world, I dont think it is to anybodys great surprise that the most powerful one is located in Japan. This new Japanese supercomputer has just recently earned the top spot among all the supercomputers in the world with a performance that makes other supercomputers look like a TI-82.

Known as the "K Computer", this device is three times faster than its closest rival from China, which previously held the number one spot, according to Professor of Electrical Engineering and Computer Science at the University Tennessee at Knoxville Jack Dongarra. Dongarra also keeps the official rankings of computer performance.

The K Computer, which was created by Fujitsu and is located at the Riken Advanced Institute for Computational Science in Kobe, Japan, represents an incredible step forward in the realm of speed. This computer will also, more than likely, become a great sense of national pride for Japan, especially for computer scientists, who take the race to have the fastest computer in the world very seriously.

According to Dongarra, "Its a very impressive machine. Its a lot more powerful than the other computers." The latest ranking of the top 500 computers is determined with a simple mathematical equation. The computer who gets to take the top spot is able to make 8.2 quadrillion calculations per second which also calculates to 8.2 petaflops per second. The performance of the K Computer is the same as linking around 1 million desktops.

Supercomputers have many uses including earthquake simulations, climate modeling, nuclear research and weapons development and testing. Businesses also use supercomputers for oil exploration as well as rapid stock trading. However, building a supercomputer isnt cheap and it usually involves connecting thousands of small computers in a data center.

The K Computer is made up of 672 cabinets filled with system boards. The K Computer is considered to be energy-efficient even though it uses enough electricity to power around 10,000 homes at an estimated cost of $10 million annually. Id hate to see the statistics for the non-energy-efficient ones. The lab that the K Computer calls home is planning on increasing the size of the computer to 800 cabinets which is predicted to raise the speed of the supercomputer that is already faster then its five closest competitors.

The K Computer received its name from the Japanese word "Kei" which translates to 10 quadrillion, the overall goal for the number of calculations the supercomputer should be able to perform. The previously leading supercomputer was Chinas Tianhe-1A which was located at the National Supercomputing Center in Tianjin, China. The Tianhe-1A was the first Chinese supercomputer to hit the top spot which acted as a beacon of the countrys growing technological prowess.

The fastest supercomputer in the United States is located at the Oak Ridge National Laboratory in Oak Ridge, Tennessee. It placed third behind the K Computer and the Tianhe-1A. Countries in Asia have made sizable investments in supercomputing and currently dominate the upper echelon of the field. Japan and China alone hold four out of the top five spots.

However, when it comes to the top 10, the United States is still the leader, holding five of the top 10 spots. Japans top supercomputer ranking marks the countrys first since 2004. The United States and China were previously the only countries to hold that title. These rankings, issued every six months, are frequently changed and reflect just how fast computer power is advancing.

Multileader Styles

Sabtu, 22 Maret 2014

AutoCAD 2008 gave us Multileaders. I have previously posted on them here and spoke about their general use, multi leadered leaders. Now lets take a look and see how to set up a Multileader style.

Let’s start by creating a new Multileader Style. A Multileader style works just like any other style in AutoCAD. In fact, it has many of the same settings as the dimension styles do. Open up the Multileader style manager. Click the NEW button on the right. It starts you off by copying one of your current styles from the drawing file.

There is a default style called STANDARD. I recommend that you create your own default style that is called anything else except standard. This is true for all styles, if you can help it. The reason is that everyone using AutoCAD has a style called standard because it comes that way. If anyone copies your Multileader (or text, or dimension, or etc.) from your file and places it in theirs, it will take on the style attributes called standard that are in their file. Their STANDARD style might not be set the same way yours is! But if you give it a unique name, it is less likely to take on the wrong attributes.

I will call this one ml-001. No reason, only that it isn’t standard. When you give your new Multileader style a name, you have the option of making it annotative or not (meaning that it will be scaled by the annotative scaling feature.) Don’t worry, you can change this later if you wish.

The style Manager has three different tabs; Leader Format, Leader Structure, and Content.

Leader

This is where you set the type, color, linetype, arrowhead, and break size.Most of these items are pretty easy to understand, so I won’t go over every setting option. But here are what I feel are the most important:

Type:Straight, spline or none.The straight setting creates a “straight” lined leader.The spline creates a curved lined leader.
Color, Linetype, Linewight: use these to set the color, linetype, and lineweight for the leader.
Arrowhead Symbol/Size: This works just like the dimension style setting for arrowhead. Choose one or choose a to use a block you created. That is what your arrowhead will be and what size it will be.
Leader Break Size: Controls the settings used when adding a dimension break to a multileader.

Leader Structure

This tab is where you can set the constraints, structure and scale of the multileader:

Constraints-Maximum Leader Points: Specifies a maximum number of points for the leader line.
First Segment Angle: Specifies the angle of the first point in the leader line.
Second Segment Angle: Specifies the angle of the second point in the multileader landing line.
Landing Settings: Controls the landing settings of the multileader.
Automatically Include Landing: Attaches a horizontal landing line to the multileader content.
Set Landing Distance: Determines the fixed distance for the multileader landing line.
Scale: Controls the scaling of the multileader.
Annotative: Specifies that the multileader is annotative.

When the multileader is not annotative, the following options are available.

Scale Multileaders to Layout: Determines a scaling factor for the multileader based on the scaling in the model space and paper space viewports.
Specify Scale: Specifies the scale for the multileader.

Content

This tab contains the controls for the content of the multileader style.

Multileader type: You can choose from Mtext, Block, or None.

Here are the options associated with the Mtext type Multileader:

Default text: this text will be inserted in to the leader by default. You can always change it.
Text Angle: Always right reading, As Inserted, or Keep Horizontal.
Style, Color, Height: set the text style, color and height.
Always Left Justify: well, check this box and your multileader text will always be left justified.
Frame Text: Check this box and your text will have a frame around it.
Leader Conection – Left Attachement: if your text is on the left, then this setting tells AutoCAD where to place the landing, center, top, bottom, etc.
Leader Connection-Right Attachement: same as above, but when on the right.
Landing Gap: the gap between the landing and the text.

Here are the options if BLOCK is set for the multileader type:

Source Block: choose form several premade blocks, or create your own.
Attachment: sets how the block will be attached to the leader.
Color: set the color

Most of these settings are obvious and are easily figured out. Some might be a little tricky. Just set these the way you want them and save the style.

Happy CADDING.

What is a Class

Selasa, 18 Maret 2014

Welcome back to Java Code Online. Class is the most commonly thing in Java. Having a good understanding of class is essential for getting a firm grip on the Principle of OOPS and Java itself. A class is called the blueprint of an Object. Everything that is done in Java, has to be enclosed within a class.

As I said before that the class is a blueprint of an Object, it is used for making Objects. I Java we know that everything is an Object, and if we dont know then we must know this. Java is built on the Principle of OOPS and is totally Object Oriented. So Java see everything as an Object.

I will take you through a through understanding of this concept. A class is used to define a new data type, and normally a separate class is used to make Objects of this new data type. Think of a class as something which defines what an Object knows and what an Object does. Therefore a class is also called a template for an Object and an Object is called an instance of the class. Thus a class contains the instance variables (things which an Object knows) and methods (things which an Object does).

A class is just like a blueprint and it covers every intricate detail about the Object that will be made from it. The normal structure of class is that it defines everything about an Object, so suppose that your application consists of some Objects, and so you make classes for each. Now you define a main class which will initiate all the calling procedure.

The main class always contain the method "main". This method tell the JVM that this is the main class and it need to start execution from here. Once in the main class, you can define Objects of other classes that you have made. I will take a simple example to clarify my point.

// This program declares two Car objects.
class Square {
int width;
int height;
}

class SquareDemo2 {
public static void main(String args[]) {
Square mySquare1 = new Square();
Square mySquare2 = new Square();
int area;
// assign values to mySquare1s instance variables
mySquare1.width = 10;
mySquare1.height = 20;
/* assign different values to mySquare2s instance variables */
mySquare2.width = 15;
mySquare2.height = 15;
// compute area of first Square
area = mySquare1.width * mySquare1.height;
System.out.println("Area is " + area);
// compute area of second box
area = mySquare2.width * mySquare2.height;
System.out.println("Area is " + area);
}
}

The first System.out.println results in:- 200
The second System.out.println results in:- 225

Now you must be wondering about so many new things, I have shown above. I will cover each of them.

Here we have defined two classes Square and SquareDemo2. The first class is used for making an Object of type Car. The second Class uses this new data type for making new Objects. Now as told before, the execution begins from the class containing the "main" method.

Now as you can see that there are two different outputs for the two Objects, this shows that both the Objects are unique and are independent of each other. Here System.out.println is used for displaying the results at the console or output screen.

The lines starting with // are skipped by the Java compiler. Infact the // is the syntax for Comment in Java. These are very helpful in explaining the functioning of the code.

If you have any problems with the code that I have explained right now, then do leave me a comment and I will try my best to clarify your doubt.

The most important thing that you must have noticed here is the parameter "new". This is the magic keyword of Java and is used for creating new Objects. I will discuss more on creating a new Object in my later posts.

I hope the article was helpful in explaining you about What is a Class. If you like this article then do leave a comment. For more information on Java, keep buzzing Java Code Online.

Best Practices to write JUnit test cases in Java

Sabtu, 15 Maret 2014

JUnit best practices in Java

No doubt writing good JUnit test cases is a rare skill just like writing good Code. A good, well thought and well written JUnit test can prevent several production issues during initial development or later maintenance in Java application. Though one can only be perfect in writing JUnit test by practice and a level of business knowledge which is important to envision different scenarios on which a method gets called, some best practices or experience of other developer may help to guide other programmers. In this Java article I am sharing some JUnit tips and Junit best practices which I have learned and follow while writing unit tests using JUnit for Java programs. One of the book which helped me a lot is Pragmatic Unit Testing in Java with JUnit by Andrew Hunt and Dave Thomas, This book shares lot of JUnit best practices which is worth reading and learning if you are serious about Unit testing using JUnit. Never undermine importance of automated testing and test cases written by Developer who writes the code and that's the reason many company are asking programmer to design, code and provide unit tests during there Java interviews. These JUnit best practices not just apply to JUnit but to any other testing framework as well like TestNG, they are more on testing and writing test cases which is more important skill than tool like JUnit or TestNG.

Remove Snap do

A concerned reader asks: Snap.do has hijacked my web browser. Is it safe? How do I get rid of it? Heres what you need to know about this so-called Snap.do hijacker malware.

Snap.do is a browser help object. Authors of this web browser plug-in say that they want to enhance your web browser and simplify the way you search the web, share favorite information, work or even play. Sounds good, right? It seems that they really care and want to help you. But hold your horses, Jack! :) Things are often not what they seem to be and thats particularly true for snap.do web browser hijacker. It comes with a cost and the main question is: are you willing to pay the price?

First of all, snap.do and some other Resoft products are considered to be potentially harmful or even malicious, not to mention how annoying they can be. For example, TrendMicro, an antivirus company, classifies snap.do toolbar as spyware and web browser hijacker and they have a good reason for that. According to Resoft privacy policy, their products, including snap.do collect the following information:

1. The Internet domain and IP address from which you access the Resoft Products;
2. Screen resolution of your monitor;
3. The date and time you access the Resoft Products;
4. The page you are visiting with the Resoft Products
5. If you linked to a Resoft website from another referring website, the address of that website.

By using the Resoft Products, you are consenting to have your personal data transferred to and processed both within and without the United States of America

Typically, snap.do installs itself as a web browser toolbar (BHO) but it may be installed with additional functionalities as well. This browser helper object can be downloaded from its official website and may also arrive bundled with other software, usually freeware. We havent seen any questionable routines or drive-by downloads that might be related to malicious software and snap.do. Whats interesting, though, installers downloaded from free video streaming sites and other shady or rogue websites are very aggressive and even if users made sure that the check boxes asking to install add-ons were disabled, snap.do virus was still installed on their computers.

Snap.do works on all major web browsers: Google Chrome, Mozilla Firefox and Internet Explorer. It doesnt work on Windows XP. Installer simply fails to initialize properly. So, XP users are safe. Once installed, Snap.do hijacker modified various web browsers settings. It changes home page to http://feed.helperbar.com and adds additional search engine provider which redirects users to http://search.snap.do. Each time user opens a new tab the web browser goes to http://search.snap.do instead of blank page, Google or any other website of your choice.

Snap.do removal can be a really challenging task, especially when it comes bundled with other software. Even though, snap.do authors ensure that it can be uninstall from a computer very easily, using the programs own normal uninstallation process, but thats not quite true. It leaves so many modified web browser settings and Windows registry keys and you cant ignore them because they simply change the way you use your web browser. For example, even if you removed Snap.do via Control Panel, modified search engine settings remain untouched. As a result, searching directly from web browser address bar returns results from http://search.snap.do rather than Google. By the way, the plug-in modifies Windows registry and enables its automatic execution at every system start-up. What is more, snap.do infection may cause your web browser to stop working.

To remove snap.do from your computer, please follow the removal instructions below. It will show you how to remove this browser hijacker in Mozilla Firefox, Google Chrome and Internet Explorer. Make sure to uninstall snap.do via Control Panel first and only then proceed to the next steps, unless of course its not listed there. Have you been hijacked by Snap.do?

Comparison of Free Vs Paid Internet Security Top 10 Free and Paid Products

Jumat, 14 Maret 2014

First it is useful to point out who is choosing free software vs. paid programs. When new computers are sold, they are typically pre-loaded with at least one full featured security suite - available as a free trial for a month or two. This recommended paid product is optional and is made available for those who are new to computers, and may not be aware that alternatives exist, or where to go to find them - knowing that most who default into this category will opt to follow recommendations and stay with, and pay for the program.

On the other hand, if youve been around the block a few times, you have by now enough savvy to know that anyone will try to sell you anything. Youre likely aware of other options and programs available to achieve the same results - whether self taught, by word of mouth, or doing your own web research. Regardless, you still end up wondering how exactly can free internet security compare or compete with the paid versions?

Contents: Whats the difference?

Paid internet security suites are designed for optimal performance and dependability. They include all the components that make up a comprehensive package for maximum computer protection - and feature live, accessible customer service. These components are a combination of - anti-virus, anti-spyware, ad ware, anti-malware, a firewall, anti-phishing detection, and recently, some form of live, real-time protection - detecting any malware activity - which may already be in progress - by continuous scanning for anything out of the ordinary. Protection like this is found in the full-featured, all-in-one, or premium security suites.

Free versions are individual components used in combination with other free components to custom build a comprehensive security defense. The idea is that combining individual free programs - achieves the same level of protection found in the paid versions. For example, I may start with a free anti-virus, then add a free anti spyware, adware, and malware program, then consider a firewall, and some sort of real-time protection to expose suspicious activity unidentified by all the others. These components together essentially resemble what you will find in an all-in-one security suite. Though I may not have access to customer support, how often really will I need to contact them? Maybe only if their service is unavailable for some reason, which usually means its on their end anyway - and will soon be resolved.

Performance: Is one more effective than another?

The answer is - not by much. Ive reviewed various results published by reliable sources. The trend seems to favor the paid products, but only by about 1% to 10% average, regarding performance and dependability. Ive put together a list consisting of the most highly rated free and paid internet security software offers. According to most resources available, these 2 groups reflect the most commonly agreed upon results. They are not in any particular order - as they seem to vary slightly from year to year. The fact that they are or have been consistently highly rated, and remain in the top 10, supports their reputation. Keep in mind that most free versions of internet security, also offer paid upgrades as well - usually named something like Pro, or Premium. You can search and compare them on your own if interested in knowing more about specific features or details for each.

Free Internet Security:

1. Avast.com - Antivirus
2. Avira.com or Antivir
3. AVG.com Antivirus
4. ZoneAlarm Firewall - Checkpoint.com (formerly Zonelabs)
5. Adaware - Lavasoft.com
6. Microsoft Security Essentials - microsoft.com/security_essentials
7. Comodo.com
8. Threatfire.com - (compliments most other components with real-time protection)
9. PandaSecurity.com - Panda Cloud
10. SUPERAntiSpyware.com - Super Antivirus

Paid Internet Security Suites:

1. Symantec.com - Norton Antivirus
2. McAfee.com
3. Avast.com - Premium
4. Kaspersky.com - Kaspersky Lab Internet Security
5. Gdatasoftware.com - G-Data.
6. Bitdefender.com
7. PCTools.com - Internet Security
8. F-Secure.com
9. Webroot.com - Webroot Internet Security Essentials
10.Trendmicro.com - Trend Micro

There are very good reasons supporting both decisions:

The consensus seems to validate that free versions are as reliable as the paid ones. People who tend to know more about internet security and are more computer/internet savvy in general will recommend the free products hands down. But their preferences are based on knowledge that many of us neither have, nor are even interested in - which is a solid argument for: go ahead and pay - they know more than I do. So it really comes down to what kind of operator are you? Do you have work to do and dont mind paying for reliable protection and piece of mind? Or are you more inclined to decide for yourself which components to include in your customized defense? There will always be choices - free alternatives to just about anything you can install on your computer.

Autodesk Homestyler App for iPad Released

Kamis, 13 Maret 2014

Autodesk has released another free iPad design app. This time it is their Homestyler home design software. Homestyler has been around since 2010 as a browser based program. This program provides a 2D or 3D design tool that helps in interior design and floor layout. Contractors can use it for remodels, architects can use it to quickly generate a floor plan, and interior decorators can choose from a multitude of commercially available appliances, furniture, doors, windows, and other finishing touches in a range of colors and designs.

Homestyler allows for real time design that can blend high-quality 3D models from popular products. It is very simple to use and is now an iPad app. This is a great platform for this type of design tool. Designers can take their iPad to a client meeting or on the job site and quickly generate a design plan. One of the great benefits to using Homestyler is the fact that users can access a library of design items that actually exist in the real world.

“ Weve taken home design to a new level of ease with the Homestyler app for iPad. The app is unique because it can transform a single snapshot into a virtual home design playground,” said Samir Hanna, vice president of Consumer Products at Autodesk. “Extending this technology on iPad lets our users express their creativity on the go, tap the existing vibrant community to find inspiration for their home and showcase their personal style with greater ease than ever before.”

“The Homestyler app lets users tap into more than 1,500 Sherwin-Williams colors for inspiration as they create their perfect space," says Jackie Jordan, director of color marketing, Sherwin-Williams. "Color is a critical element of design, and the new iPad app is a great way to explore the impact of different hues and the relationship between wall colors and furnishings."

You can read more about this new app from Autodesk’s Press Release.
You can try the Homestyler app on iTunes.
No iPad, you can go to the browser based version.

Now Autodesk, release this for Android.

Want to ask Autodesk a Question

Selasa, 11 Maret 2014

My last post, Does Autodesk Listen to its Users?, asked you if you thought Autodesk listens to its users, as the title implies. If you havent already, participate in the poll. Select the percentage that you feel Autodesk does listen at.

I want to steal (I mean borrow) another idea from Steve Johnson and give you a chance to ask Autodesk a question.

Keep it reasonable, and like Steve said, they wont be able to answer pricing questions. But what do you want to know? Release cycle issues, major bugs, whats in store for AutoCAD, Revit, Civil3D, etc.

I am going to San Francisco in two days for a meeting with Autodesk. There will be many bloggers there, members of the press, and Autodesk officials. I will be able to speak with several officials, so if you have a simple enough question post it here as a comment and I will see what I can find out. I can not make any promises except that I will try. I know, there is no try, only do or do not, but I will see what I can do!

What do you want to know?

Does Autodesk Listen to its Customers Part 2

Senin, 10 Maret 2014

I asked on a previous post if you thought Autodesk listened to its customers. I just spent a day at the Autodesk office in San Francisco taking with several people from Autodesk. I was also able to spend some time with fellow blogger Steve Johnson. He took the time to interview three key people at Autodesk. They were: Shaan Hurley, Eric Stover, and Jon Page. I wanted to make sure you had to opportunity to watch Steves video interview. There are two of them and they provide a detailed response to this question.

Thank you Steve for conducting these interviews and for providing us with this valuable info. Great job as always Steve.
