Which Is Easier to Learn Java or Python

When it comes to learning an object-oriented programming language, you might consider starting with either Python or Java. While Python can be more user-friendly than Java, as it has a more intuitive coding style, both languages do have their unique advantages for developers and end users. However, if you are just beginning your path towards a programming career, you might want to start by learning Python, as it is less complex. On the other hand, you will be ahead of many of your colleagues if you are able to understand both. With that in mind, here are the main similarities and differences.

 

Java

Java is unique in its own way and for an advanced programmer, no problem to use. The first Java version 1.0 was released in 1995. By 2004, Java 5.0 was released; this version saw the insertion of generics into the Java language, providing Java with more efficient code and type safety. To date, the latest version of Java is SE 8, and it made its debut in 2014.

Currently, it is widely used as the key programming platform on smartphones and tablets. Additionally, Java programming language forms a large part of the basis for Android’s operating systems. Java syntax is primarily a derivative from C++ and combines universal, organized and object oriented programming that offers automatic memory management. Using Java byte-code is advantageous to porting since it has similarities to machine code. Other benefits to Java include:

•Static typing
•Curly braces used for noting the start and end of functions
•Programs are larger
•Does not compile native bytecode
•Can be run on any operating system that can run the Java Virtual Machine
•Cannot change data types of variables
•Object-oriented programming is mandatory

 

Python

Python was first released in 1989. As a high-level programming language, it makes a strong case for readable code. In addition to supporting object-oriented programming, it also supports imperative and functional programming. This multi-paradigm language is also structure supportive. It offers ‘meta-programming’ and ‘logic programming,’ as well as ‘magic methods.’ Other features include:

•Duck typing (Strongly typed)
•Uses whitespace to convey the beginning and end of blocks of code.
•Programs are small and therefore run much faster
•You need less code to create a program
•This program is slow in execution
•Compiles native bytecode
•You can assign a string to a variable that once held an integer
•Easier to read and understand relative to Java
•Is not supported across a wide variety of platforms
•Object-oriented programming is optional

 

Variances

Both of these development programs come with their strong suits. While Java allows you to enjoy cross-platform support, you can still execute Python on at least 10 different operating systems. You need to determine what your end goal is before you decide on which program to use. Java, however, is not recommended for beginners as it is a more complex program. Python is more forgiving as you can take shortcuts such as reusing an old variable.

Additionally, many users find Python easier to read and understand than Java. At the same time, Java code can be written once and executed from anywhere. A benefit to the Java platform is that it lets you download questionable code and run it in a secure environment, which cannot affect its host system. Furthermore, Java is network-centric, meaning you can create network-based applications.

Whichever you choose to learn is based upon your preferences, determination, and background. If you already comprehend the basics of Python, you might want to expand upon your knowledge before moving on to Java. However, if you have the time and will, learning Java allows you to program for a wide variety of environments that might make it more fulfilling in the long run.

Performance Testing: Latency, Load, Stress, or Soak?

Written by Natalie Lehrer

5 heavy load

How well does your web hosting perform? Are you sending web pages in a timely way to visitors to your site? Is your application correctly handling simultaneous requests? Do you actually know what can be measured – and which measures are relevant to your situation? Web hosting performance testing can give you valuable information that can let you keep visitors longer on your site, make sure you can accept the right number of simultaneous visitors, handle overload situations and detect possible design or programming deficiencies.

 

Latency or How Long It Takes to Get Back to a Visitor

Let’s start with the case of just one visitor (naturally, you’ll probably be aiming for rather more, but we’ll discuss this below.) Normally, you want the response time for that visitor to be as fast as possible. In other words, between the moment when the visitor clicks to send you a request and the moment the visitor sees your response, the least time possible should elapse. This ‘latency’ can however be determined by several different things, including the power of your web hosting platform, the size of your network connection and the power and network speed of your visitor’s computer. You can improve the first two, but the last two are out of your control (although keeping your web pages simple may help.)

 

Performance Under Load

Ideally, you should have an idea of how many visitors are likely to access your web hosting platform at the same time. If this is not feasible, then you should at least know how many average or typical users can actively work with your site simultaneously, and plan ahead for options to increase capacity if you need to. Different solutions, either free or paying, online or in-server, are available for conducting load tests with up to a few million simulated users or more. Whichever solution you choose, make sure your test is representative of both user numbers and types of activity, including number of pages called per hour, number of requests for database information, ‘think time’ and so on.

 

When It’s All Just Too Much

If your web site is significantly more popular than you imagined, your web hosting facility may not be able to cope with all the traffic. Then what happens? Does your site send out a polite apology about lower performance while stopping any new connections, or does it just crash without warning? Stress tests are designed to find out what (really) happens under conditions of excessively high loads. How much this affects you will depend on what kind of website you operate. A web site for a bird spotting association that simply crashes may just be an irritation. A web site selling hot new fashion articles that simply crashes could lose you important revenue and customer loyalty.

 

A More Technical Test

The soak test is done by starting your web site or application and leaving it to run (normally) for an extended period of time to see whether this produces any abnormal conditions either in the application or in the web hosting platform it runs on. One example would be memory leaks, a common enough problem when an application uses some main memory, but fails to return it for general use when it’s finished with it. Testing for these kinds of conditions typically requires technical expertise, for example by the person or team designing the application in the first place.

 

Finally, Who is the Judge of ‘Good Performance’?

Performance, ultimately, is all about making sure customers or end-users are satisfied with what they experience. Your web hosting platform may be supercharged in processor power and memory, yet they may still complain. Or it may be far more modest and still reply adequately to user expectations. Falling traffic and user comments on your blog (or similar) may indicate a problem, but prevention is always better than cure. There’s only one way to find out what users really want, and that’s to ask them. Armed with this information, you can then do the right performance tests and confirm or tweak afterwards, as appropriate.

Google Apps Work HostGator

What do you do when one of the world’s most innovative companies of all time reaches out to you and your business and says, “We want to help?” Here’s a hint: take their hand and say “thank you” without any hesitation. Some things just make sense… and sometimes saying “no” makes no sense at all.

Cue, the mighty Google. What can be said about the company whose name has not only become synonymous with Internet searches but has actually become a verb; an honor reserved for only the most creative and unique individuals and entities in existence. Google has long been a standout for more than what they bring to the table; who they invite to the table with them is of equal importance. And, this time, they are inviting you.

Google Apps is a suite of tools, most of which you’re likely already familiar with (Gmail, anyone?) that are designed to streamline your business. HostGator now uses Google Apps internally for our email, document sharing, video conferencing, calendars, and so forth. Google Apps has literally changed the way we function, day to day.

Here is a brief snapshot of the things Google wants to do for you, aside from provide you with an excellent suite of fully useable tools:

  • Help ensure your business is HIPPA, PCI, SOX compliant
  • Provide you with their SLA for your internal AND external mail
  • Reduce your required IT costs
  • Improve your communications with conference functions
  • Establish a secure backbone for your internal and external interfacing
  • Maximize your project management efficiency with synced calendars
  • Bolster your branding and SEO efforts
  • Facilitate editing in multiple document formats without purchase of a license

 

This is a very big deal. In short, these benefits are amazing. Whether for your independent consultancy, your medium sized growing business or if your company has recently gone public, Google Apps for your business is possibly the best and arguably the most important move you can make. The biggest benefit of all? Making your life more simple. Now HostGator can help as well. Not only are we customers of Google ourselves, but we’ve now partnered with Google to offer Google Apps for business directly to you.

Google Authorship Dead In 2014?

Written by Kyler Patterson

authorship-featured
If you’ve searched for anything on Google in the last month or so (who hasn’t?), you may have noticed slight changes in the results. First, the author pictures next to the results conspicuously disappeared. Then, videos started to vanish for most results (except those of YouTube and other sources where video is a primary source of content). Now, author names have disappeared. According to John Mueller from Google’s Webmaster Analytics team, Authorship has indeed been removed from your search results.

Is Google Authorship Dead

A few months ago, the same search would have displayed the associated Google+ profile picture and related information, as shown in the image below from our prior Authorship blog post:

What Authorship Looked Like

 

Now the posts are stripped down to provide you the content that you’re looking for without the fluff.

 

Why Was Authorship Removed?

If you ever set up authorship, then you know it was not the easiest process to start with. There were several steps involved, including an update your site’s code to add the markup. If you were using a CMS like WordPress, the markup wasn’t too hard, but HTML sites were a little harder to modify. Since the entire ordeal wasn’t an easy 1-2 step process, it had a low adoption rate.

As stated in Mueller’s post, and speculated by many, Authorship simply did not have any direct impact to an increase in clicks or rankings. A direct quote from the post:

“If you’re curious — in our tests, removing authorship generally does not seem to reduce traffic to sites. Nor does it increase clicks on ads. We make these kinds of changes to improve our users’ experience.”
 

Is Authorship Completely Dead?

From search results, it appears to be mostly (though not entirely) gone. As explained by Mueller, search queries will still show relevant posts from your Google+ connections with their information. So if you were connected with an author and searched for information pertaining to them, then you may see something like this:

The Google Authorship Update

Keep in mind, the rel=author markup didn’t just affect search; social media displays this information as well. With Pinterest, you can stand out with rich pins. As you see in the picture below, you will still see the author markup:

Pinterest-Tips-Tricks

 
You can also see it on Twitter with Twitter cards as shown below. If you’re able to edit the author Twitter handle, you’ll also get another spot in the author section.

 

Conclusion

Although authorship has been mostly removed from Google search, it still does serve a purpose and cannot be entirely considered dead.. perhaps undead… zombie(?). You don’t necessarily need to go through the process adding the authorship through Google+ to include the rel=author tag, but who wouldn’t want a good branded back link on a Google product?

What do you think? Is authorship just dead and should never be touched again or will you still be including it on your blog? Let us know in the comments!
