Honolulu , Hawaii net Training

This section of our beginning python training class always stumps students. Firstly, because they need to know the difference between a function and a method. Secondly, they need to understand object oriented programming concepts. Thirdly, they need to realize that python has three types of methods. Then they need to know how to use each method, which means they need to know the purpose of each method type. Then they have to understand mutable versus non-mutable types. The list goes on. As part of our python tutorial, I hope to shed some light on this confusing topic.

To begin, the difference between a function and a method in python is that a method is defined within a class. Here is an illustration:

#function

	def greeting():
	                print "Hello, I hope you're having a great day!"

	class HSGPrinter(object):
	                #method
	                def greeting(self): 
	                                print "Hello, I hope you're having a great day!"

As should be obvious, the second definition of greeting is encapsulated within the HSGPrinter class and is , therefore, refered to as a method.

The astute reader will notice that the greeting method contains one parameter named self. For those who know C++ , Java or C#, self is equivalent to this i.e. it is a reference to the invoking object:

How to add an item to a dictionary

To add to a python dictionary is very easy. First create a dictionary, and then associate a key with a value.

a = {'cat',"furry thing"}
a['dog']="typically likes to run and is very loyal"
print a

Here is what is printed:

{'cat':'furry thing', 'dog':'typically likes to run and is very loyal'}

	Here is a list of the organizations that use Python. This list is periodically updated by HSG’s software fans as well as the community at large.

	 

	Web Development

	1.       Yahoo Maps

	Yahoo acquired Four11, whose address and mapping lookup services were implemented in Python. Yahoo Maps still uses Python today, as can be seen by examining its URLs.

	 

	2.       Yahoo Groups

	A comprehensive public archive of Internet mailing lists that was originally implemented in pure Python. At one point Scott Hassan, one of the founders of Findmail/eGroups (the company that was later acquired by Yahoo), reported that they had 180,000 lines of Python underlying everything from their 100% dynamic website to all email delivery, pumping out 200 messages/second on a single 400 MHz Pentium.

	 Technology is wonderful. It helps us run our businesses and connects us to the world. But when computer problems get in the way of getting what you need to get done, you can go from easygoing to mad-as-a-hornet in 3 seconds flat. Before you panic or give in to the temptation to throw your computer out the window, try these easy fixes.

	5 Common Computer Problems 

	
		Sluggish PC


	A sluggish PC often means low disk space caused by an accumulation of temporary Internet files, photos, music, and downloads. One of the easiest fixes for a slow PC is to clear your cache.

	The way you’ll do this will depend on the Internet browser you use:

	
		Chrome– On the top right-hand side of the screen, you’ll see what looks like a window blind. Click on that. Click on ‘History’ and hit ‘Clear Browsing Data’.


	
		Safari– On the upper left-hand side, you’ll see a tab marked ‘Safari’. Click on that. Scroll down and hit ‘Empty Cache’.


	
		Internet Explorer– Click on ‘Tools’ and scroll down to ‘Internet Options’. Under ‘Browsing History’ click ‘Delete’. Delete files and cookies.


	
		FireFox – At the top of the window click ‘Tools’ then go to ‘Options’. Select the ‘Advanced’ panel and click on the ‘Network’ tab. Go to ‘Cached Web Content’ and hit ‘Clear Now’.


    
        
            
                
                    Tech Life in  Hawaii
                     
Learning complicated languages such as java, C++, and Linux becomes a bit of a challenge when your every-day life constitutes living in paradise! However, Hawaiian consumers ultimately bear huge expenses when transporting goods to the island.  Deliveries of consumer goods to Hawaii are subject to the extremely high operating costs imposed by the Jones Act. This also makes Hawaii less competitive with West Coast ports as a shopping destination for tourists from home countries with much higher taxes (like Japan).  Alas, for those that want to catch up on the latest technologies, the University of Hawaii sports a Center for Cultural and Technical Interchange between East and West on the Manoa campus. The university maintains institutes of astronomy, geophysics, marine biology, and biomedical research and the Lyon Arboretum in Manoa Valley. 

                    
                            
                
                         The trouble with programmers is that you can never tell what a programmer is doing until it's too late. Seymour Cray

                Software developers near Honolulu have ample opportunities to meet like minded techie individuals, 
                collaborate and expend their career choices by participating in Meet-Up Groups.  The following is a list of 
                Technology Groups in the area.

                        A successful career as a software developer or other IT professional requires a solid 
                        understanding of software development processes, design patterns, enterprise application architectures, 
                        web services, security, networking and much more.  The progression from novice to expert can be a  
                        daunting endeavor; this is especially true when traversing the learning curve without expert guidance.  A
                        common experience is that too much time and money is wasted on a career plan or application due to misinformation. 
                    
                    
                        
                            The Hartmann Software Group understands these issues and addresses them and others during any 
                            training engagement.  Although no IT educational institution can guarantee career or application development success, 
                            HSG can get you closer to your goals at a far faster rate than self paced learning and, arguably, than the competition.
