Philip Greenspun's Weblog:: "Java is the SUV of programming tools
Our students this semester in 6.171, Software Engineering for Internet Applications have divided themselves into roughly three groups. One third has chosen to use Microsoft .NET, building pages in C#/ASP.NET connecting to SQL Server. One third has chosen to use scripting languages such as PHP connecting to PostgreSQL and sometimes Oracle. The final third, which seems to be struggling the most, is using Java Server Pages (JSP) with Oracle on Linux. JSP is fantastically simpler than 'J2EE', which is the recommended-by-Sun way of building applications, but still it seems to be too complex for seniors and graduate students in the MIT computer science program, despite the fact that they all had at least one semester of Java experience in 6.170.
After researching how to do bind variables in Java (see the very end of, which turns out to be much harder and more error-prone than in 20-year-old C interfaces to relational databases, I had an epiphany: Java is the SUV of programming tools.
A project done in Java will cost 5 times as much, take twice as long, and be harder to maintain than a project done in a scripting language such as PHP or Perl. People who are serious about getting the job done on time and under budget will use tools such as Visual Basic (controlled all the machines that decoded the human genome). But the programmers and managers using Java will feel good about themselves because they are using a tool that, in theory, has a lot of power for handling problems of tremendous complexity. Just like the suburbanite who drives his SUV to the 7-11 on a paved road but feels good because in theory he could climb a 45-degree dirt slope. If a programmer is attacking a truly difficul"
