JSIG session : Java Development on Mac OS X

Sam Dalton and I are running a JSIG session about Java development on Mac OS X next month...

Java Development on Mac OS X
The Mac OS X platform is gaining ground with developers because of its stable UNIX based architecture, easy to use UI and integrated Java runtime. This session discusses experiences of Java/J2EE development on Mac OS X, talking about the advantages and disadvantages of adopting the platform. The session also demonstrates some of the open source and commercial development tools that the speakers use on a regular basis, discussing any "gotchas" that have been encountered along with way. If you�ve never seen a Mac or are thinking of buying one then this session is for you.

The session is taking place on the 26th of March in Sun's offices near London Bridge, between 12 and 2pm. Full details (including how to sign up) can be found on the JSIG website. As the abstract implies, it's a good opportunity to see what Mac OS X looks like if you've not seen it before. Besides, it's also a good excuse for us to demo our shiny Macs. ;-)

• Any chance of a writeup of how it goes?
  I am in Atlanta, but would love to hear how this goes and read a writeup or minutes of the meeting if possible.

  Will do - and we'll also post some slides somewhere. I'm toying with the idea of capturing some of the session on my iSight. ;-)

• Macs on the Job
  How many Java developers use Macs at their jobs? The first Java programming job I held was at a small Mac-based shop. My second job, I had to smuggle my own PowerBook in. For the last three years, alas, I've been Windows based, at a Mac-hostile (or at the best, Mac-ignorant) company. Which is ironic considering the last three years have seen Mac OS X grow as a fantastic Java environment.

  So, for Mac weilding Java developers, how'd you do it? Was your company Mac friendly from the outset? Were you successful in requesting a Mac even if it weren't the norm? Or did you smuggle in your own laptop?

  I'd particularly like to know about Mac friend shops in the Atlanta area. :)

• Macs on the Job
  I've definitely had good success using my Mac on the job. To be honest, I work for a smaller company and my position has more freedom to choose my own tools -- but I use it in many customer environments including a Fortune 500 company -- everyone normally reacts the first time I bring it out, then once they see how well it works and all I can do, they just accept it as a tool equal to theirs, or occasionally people become interested in OSX which they've never seen before.

  The power of having MS Office, VirtualPC, Keynote, Omnigraffle, Eclipse, 4 or 5 difference Appservers, Mysql etc all running on my Aluminum 15" laptop allows me to do business and development that I just couldn't do nicely before on Windows or Linux. I've been on OSX for 3 years now and so far nothing comes close... even though I'm on Linux, Windows and Solaris machines all the time.

  As for your question about requesting a Mac -- I had my own when I first came to this company and everyone thought I was a little weird, but my newest one was purchased by the company, and a colleague in the company also got one, and now others are eyeing them closely as they continue with their normal issues and I just keep working.

• A very good one
  I use Mac OS X 10.3.2, I was an adept of Linux and in
  another way of XP. From the pure OS point of view, Mac OS X is far away, the best o.s I meet. It is fast, incredibly simple, reliable and with a very good vectorized look.

  From the Java point of view, the JDK is always integrated to the OS (dixit microsoft). Morever, there's a special application format called .app that makes any java application very similar to any other application. And for the best, the JDK 1.4.2 has a better swing performance than for linux and XP.

• Macs on the Job
  jimothy,
  Mac smuggler here, in Atlanta. I have to use Win2K for my main job development activities. The stuff I do on the side is on Mac OS X (Panther). I know at the Atlanta Java User Group (AJUG) there are a few people who use Macs, but the majority of members dismiss Mac as a Java platform out of hand - which I find funny.

• No mac at work
  I use my Mac for all of my home-based development work but, alas, am barred by corporate standards to even request a Mac at work.

  I can get Eclipse and other Java tools to work faster on my work PC, but my Mac is pretty old and has a quarter of the clock speed. I think it does well, all things considered.

  One thing that really impresses me about OS X (Panther) is that memory paging performance/characteristics seem to be much improved over WinXP. On both machines I have 512MB of RAM with the same releases of JDK (1.4.2). I typically have Eclipse, jEdit, and a Java serer or two running (as well as mail, terminal, etc). This uses a fair amount of virtual memory, but OS X seems to take it in stride and my apps are always responsive. On WinXP, though, it really sucks. Even though the total memory usage sits below the amount of physical memory (meaning that no app should EVER be paged completely off to disk), I constantly have to wait for a minute plus when switching to a new app that I haven't used in a while, watching it slowly thrash with the disk and bring itself back into physical memory (I think Windows is paging the unused apps out in favor of maintaining a large file cache or something). Watching and testing this behavior over time has lead me to believe that no matter how much memory I give the WinXP machine, it is still going to page my "inactive" apps out. Is it too much to ask that if I have the memory and leave the app open that I possibly don't want the OS to write it back to disk at the first chance???

  
  Anyway, I said all that to say that I am really starting to hate using the Windows machine. Cygwin just doesn't cut it when you COULD be using a real Unix system with all of the extras.

  I'm about ready to purchase a PowerBook and start smuggling.

  I definitely feel you on the paging issue. Glaciers melt while I switch applications on Win2K. Granted, my machine could use a virtual memory boost.

  A neat trick of Java on Mac OS X is that memory for the standard libraries is shared between JVMs. So, Eclipse, jEdit, and WebLogic (for instance) running simultaneously use less memory. Apple gave some of their code to Sun to support this on other platforms; perhaps it is part of Tiger?
