[Stripes-users] What notebook would you recommend for working with Stripes and whole JavaEE stack?
Maybe it's not directly Stripes-related, but I find Netbeans and Glassfish quite memory and CPU resource hogs, more and more with each new version. My desktop development machine is quite powerful with overclocked Intel i7-920 and 12GB of RAM, but I found myself in the need of buying a notebook for part of my development. With my current old old laptop all I can do is use remote desktop to access my desktop, but it's not a convenient solution.

I'm happy with a Thinkpad t410, 4GB RAM, Intel Core i7 M620 and a OCZ Vertex 2 SSD. If you want to have fun, use a fast SSD for OS and your workspace - Backup on a daily basis(!). I promise you: If you ever developed webapps on a SSD you will never develop using a HDD again. If you have to switch back... ...it will be hard!

Substantially cheaper than getting top of the line SSD (tried some cheaper ones and they were worse than HDDs) and performance is on par. Just work one week on a SSD.

Damn, perhaps I should be asking about _software_ stack, not hardware one. Eclipse and Tomcat seem to be better for a PC than Netbeans and Glassfish are. Not at all. It really depends. Tomcat is no full stack JEE container like Glassfish. Netbeans, Eclipse or IntelliJ is out of scope. What I can tell for sure is that IntelliJ has the best web support. I think Netbeans had some problems running maven projects on tomcat and where eclipse wtp is much better. But the editor support in Netbeans is better than the support in eclipse.

Re: [Stripes-users] What notebook would you recommend for working with Stripes and whole JavaEE stack?
I run a MacBook Pro 17 early 2008... Core2 Duo CPU with a 7200RPM Seagate HDD but the primary and secondary SATA controllers are held back to 1.5 and 1.0 Gb/s respectively from 3.0 Gb/s on later models. The stock system is OK but not great for development so I supercharged it :-) About a month ago I found out that I could theoretically get 6GB of RAM in this thing (Apple still only supports 4GB) and I picked up a stick of 4GB (adding it to my 2GB) of RAM from Other World Computing and it REALLY makes a difference. Running w/ Eclipse, GlassFish, MySQL (not so hungry), Firefox and it really helps not to have to swap anymore. I wouldn't run a dev box with anything less than 6GB today. The 2nd major performance improvement is getting a SSD. True - compilation is CPU intensive not disk intensive - but starting up Apps almost instantaneously (in comparison to an HDD) is something to behold. Firefox pops open. Eclipse launches in around 5 seconds. The system launches so fast. But you do need to get a TOP end SSD in my opinion - preferably SLC over MLC though the new rave is eMLC - and although prices are coming down I wanted to get one of the best SLC SSD's I could find so I picked up an Intel X-25E 64GB (I know you said cheap and at $800 you could pick up another laptop but reliability is huge for me). I then swapped out my HDD for the SSD and then picked up an Optibay replacement for my DVD drive and put my HDD in the DVD drive bay; i.e. SSD is primary drive; HDD is secondary; and DVD drive ends up in a DVD enclosure (came with the kit). One needs a DVD less and less these days so getting an SSD and an HDD in a system is ideal IMHO. The system CPU and SATA controllers are now my bottle neck but when I upgrade to a newer Mac the SSD is going into the next system and CPU will be better :-) Personally I like to get at least 2 if not 3 years out of any given laptop.

Re: [Stripes-users] What notebook would you recommend for working with Stripes and whole JavaEE stack?
Yes. Speed is about the same and they are cheaper. They are MLC... NO... AND if so, how about reliability? Fast and cheap and having to backup your SSD every day are fine if your into that... not me... ;-) I have read too many negative stories on MLC drives and the premium on the Intel X-25E is definitely VERY high but I am extremely happy with it. IIRC you can write something ridiculous like 100GB per day for 5 years and the Intel X-25E should hold up. In any event the new trend is towards eMLC which is so new that I'm not sure I want to step right into that without waiting a little while. Hence the choice of an SLC drive. IN any event... just check out the SSD you are getting and don't just go with fast and cheap ONLY is my advice... reliability is huge for SSD... and whatever works for your pocket book and tolerance is great... I'm NOT going to get into this SSD is better vs. another as they all have PRO's and CON's. ASIDE: We are considering launching w/ servers with these SSDs (w/ SoftLayer) so there's slightly more to why it was selected.

Do you happen to have a .hs_err_BLAH (IIRC the name) file when the OOM occured... b/c if you do then you should be able to easily see what filled up... if it indeed was perm gen space or something else? It's quite common practice to have on production app servers the min and max of memory settings the same and maxed so that things don't grow i.e. set permSize AND maxPermSize to your max perm size... set -Xms AND -Xmx to your max JVM heap size... otherwise new blocks of memory will need to be allocated, copying, etc... . In development I set the min to at least 1/2 my max for the heap and set min and max perm gen to the max value as there is a lot of class re-compilation / re-loading... 256MB is usually sufficient and if that fills up its probably best to restart the app server in any event. Then there are other JVM settings to tune as well... like GC algorithm, GC threads, etc... setup your gc to print out periodically and review the data. What OS are you running on and what is your -Xss JVM setting? On Solaris for example 1MB is allocated to the stack for each thread which is overkill for almost any production app... 128k is typically more than sufficient. Performance tuning is a big area in itself and there are many things to adjust / tweak. It amazes me how many times I have seen client production app's fall over on a 32bit JVM with say 2.5GB of allocated heap... yes... if you get enough load and your app server is worked hard enough... it will fall over at 3.5 - 3.8GB (at least on Solaris).
