The 8 Nights of Java – Night 1

Posted on by
1

Given the holiday season, we thought it would be fun to share our favorite (or least favorite) features from all 8 versions of Java that have been released to date. Some features, like generics and autoboxing/unboxing, were met with a lot of fanfare and have since changed the way we as developers write code. Others, like NIO.1 and RMI, are not nearly as popular today as originally envisioned. With that in mind, we’ll be posting one entry each night on a different version of Java, starting tonight with Java 1.

Oh, we want to wish all of our readers a Happy and Healthy Holiday, as well as a Wonderful New Year!

Java 1.0/1.1 Notable Features
Sun introduced Java 1.0 (codename Oak) on January 23, 1996, with a more stable Java 1.1 released in February of the following year. These versions included:

  • Compiler and JVM runtime environment
  • JDBC
  • The beginnings of reflection
  • Inner classes
  • Thread class

From Scott:

Java 1.0 released.. well, Java! We all take for granted the ability to execute Java code on nearly every platform but back when Java was first released the idea of compiling source code into byte code and running inside a virtual machine was absolutely revolutionary. It was one of the first languages to allow developers to work freely in any environment and deploy to any other environment. Before Java, programmers tended to use the same operating system, same IDE software, and same compiler to write software that often could only run on a handful of environments. Java helped foster the open source movement allowing developers to work in Linux, Windows, MacOS, etc and deploy to any system. At a time when hardware and software systems were much more heterogeneous than they are today, Java helped improve productivity and sharing across a wide variety of landscapes.

Of course, early on there were some problems. Microsoft released Visual J++ alongside Sun’s implementation which contained only a subset of Sun’s features, as well as additional features Microsoft wrote themselves. These differences almost splintered the Java landscape within the first few years, since Visual J++ was so different from Sun’s implementation. Luckily for us, Sun intervened, successfully suing Microsoft on the basis that it violated Sun’s license agreement by releasing a version of Java not compatible with other versions of Java, helping to solidify Java as a standards-based language. In hindsight, articles like “Microsoft’s J/Direct called death of Java” written in 1997 (and comical now) would be the first of many (including a famous interview with Steve Jobs) to incorrectly predict Java’s demise. Today, Java is used in over 3 billion devices worldwide.

My favorite part of Java 1.0? The fact that the Thread class was included right away. Multi-threaded programming was still somewhat new, especially since multi-core processors were still in their infancy. Providing a new language in which developers could process tasks in parallel was pretty forward thinking, even if our thread-base implementations weren’t always perfect. Today, we tend to rely on the Concurrency API given its feature-rich convenience and stability, but never forget it’s is built entirely upon the Thread class.

From Jeanne:

Version 1.0 included Vector. While we no longer use Vector for new code, it paved the way for ArrayList and the Collections framework. JDBC is one of my favorite libraries. I use a mix of raw JDBC, ORM and Spring JDBC template these days, but JDBC started all of this. And then we have the parts of the language that stood the test of time. Plus since Sun/Oracle find it hard to actually get rid of anything from the language, we also have such fond deprecated memories such as Date’s getHours() methods. I was still in high school when Java 1 launched. I never actually worked with it directly as Java 1.2 was out before I started even reading about Java. When Java turned 10, it was cool to read Hello World(s) – From Code to Culture and see how Java got started. Or should I say how Oak got started?

FIRST robotics 2017 background check and social security number

This year, when you register to volunteer with FIRST Robotics in VIMS, you get prompted to register in Verified Volunteers so they can do a background check. In particular to determine you don’t have a criminal history and aren’t a sex offender.  For the most part, this is straightforward. You give some minimal information about yourself. And FIRST pays the cost of the background check.US FIRST - V2

 

Wait? They want my Social Security Number?

The only thing in the background check that could be considered sensitive is your Social Security Number. FIRST doesn’t get this information if you choose to provide it. But Verified Volunteers does.

I have a “real” background check for my job. So I don’t have a problem with the concept of a background check. I’m not a big fan of providing unnecessary information though. Especially given the number of data breaches lately. Luckily, FIRST says you don’t have to provide it in their volunteer screening guide:

Wait, does this work?

Yes. I chose to check the “No SSN” button. I was screened within 48 hours.

How much does it cost?

As a volunteer, it costs nothing. It costs FIRST money though. $8 for the national screening. And since I am in New York State, they also paid $65 for a state one. This adds up fast. Which means FIRST is spending many thousands of dollars on background checks.

There is a thread on chief delphi about this. It’s hard to find the relevant info without reading the whole thread so putting up this blog post for easy reference.

Sometimes I blog about a conference when I attend it. Today, I attended a number of sessions at the 2014 First Championship Conference. It was my first time attending these talks. There was a good level of quality.
