Careful with the 2650's. The PERC3 has been a sore dissapointment and the aacraid has a bug that is fairly well documented causing undeterministic crasshes.
We are in the processes or trying to work with dell to send our 2650's back and getting 1750's intead. (Note: we run RHEL 3.x)
Ya the Mac store here had a PowerBook for me to try. I think it was $100 for the week or something (that's Canadian Dollars).
I have not done a lot of really detailed analysis to see why build times are 25 minutes as opposed to 5, I just set up the nfs mount. I do think that I/O is a big bottleneck though, I didn't try RAM disk as I didn't have enough memory for weblogic, IDE and the RAM disk.
I too look forward to picking up a G5 powerbook sometime in Dec of this year as well... or a G5 workstation, still trying to organize what will work best for my needs.
Developing on the Mac is a pleasure though (for the little that I do), but if you are simliar to my situation but intend to do real work I think I would hold off or just split the load between your two machines - which isn't great for being totally mobile.
IDEA is the most responsive IDE I have used so far.
My experience is as follows (Disclaimer - I do almost all PHB stuff now) with a J2EE app running on Weblogic against an application that has 400+ tables, 200+ EJB's and 400,000+ reallines of code.
Our developers work on P4 2.6GHz machines (Linux and Windows) - so this will be what I compare to.
It doesn't compare - my Mac (1Ghz G4 with 768MB RAM) can not come close to being as productive as they are. The IO is way to slow and we use XDoclet and some other code generation tools (12,000+ files can get generated in a build). IDE's (IDEA and Codeguide) are slower but IDEA works quite well.
In order to be productive I use nfs to a Linux machine that is a Dual 1Ghz with SCSI drives. My mac build times are 5-7 times slower than the server I use (and more than that compared to the real developers in the office) and as such I just have Weblogic on the Linux server and the IDE on my laptop.
I love my mac and won't give it up, if I need to develop more I would move to a new G5 or a Linux workstation, I still need my PowerBook as I am on the road lots and manage my iLife with it:). [Course the integration with Exchange sucks except for classic Outlook]
Apple stores have demo's they will charge you but at least you can go out and and try it. I still don't think we have a large app, and am interested in the distributed build that XCode could offer as we can spend a great deal of time some days compiling and redeploying - but giving up something like IDEA would probably be more costly from a timing perspective.
It is really gonna depend on what you are looking for in your application server.
If you application is not going to be high load, or you won't need to worry about clustering then your options are more varied.
Also you should know if you are going to use Bean Managed Persistence or Container Managed Persistence. If you plan to use CMP then you need to make sure that the application server you use has good OR mapping tools. TopLink is a well repected OR mapping tool.
We chose Weblogic 4.5.1 as we needed to cluster and scale the application. Weblogic doesn't have good OR mapping tools but links really well with Toplink, we are using BMP anyway.
Webshpere is a bitch to install unless you understand Oracle or DB2 quite well.
Oracle's application server ties you to close to one vendor so we stayed away.
Enhydra looks really cool and it is OSS so you can get in and tweak stuff if you need to. I am not sure what kind of performance it can achieve though.
The biggest thing before you start to make decide is define what aspects of EJB's and such you will need and need to work well and what won't matter, this should help narrow the field down for you.
This pdf is a very good research article and i reccomend it as a starting point EJB Comparison.
Lets all step back 50 feet and see what is happening at/. the great Open Source/Free Software forum.
We gets endless complaints about stuff not being open source, not being free, companies that gets patents on software, proprietary (sp?) software, etc. (Crowd screams) "Give me the source, I need the source code".
Netscape sucks, it crashes, Mozilla will never be out, M$ has won the browser war, blah blah blah.. (Crowd Sreams)"I want a standards complant browser that is better than IE"
I could go on but I won't, i assume you get the point. This is an opportunity to get into the source that everbody must have according to the posts before. Ya it might be dirty work, coding is not glamourous it is work and sometime it is tedious. So instead of being a bunch of hypocryts (sp?) either SHUT UP about wanting stuff to be open source, or take the advantage of an opportunity to further a software project that can make a difference.
Come on people, decide which side of the fence you sit on. You want the source so you can help, OR you can't be bothered to actually help nor do you plan on it.
When you write a line of code for teh kernal you are doing someone work.. When you write a line of code for apache you are doing someones work.. When you help with Mozilla youare doing someones work..
I am also from Calgary and perhaps he is not doing it for 'Celeb' status. Perhaps he doesn't care about words printed..
Its not always about being a 'celeb', he does good work and is respected in the industry that matters to him. Calgary has lots of technology and perhaps you could focus on the positive and not the negative.. Ever heard of Jaws.. They get lots of print in the local paper.
If you purpose is to be a pessimist then so be it, if that tickles you fancy. Some of us are doing cool work in Calgary even if your not.
I have it working and it is as simple as setting up the proper classpath variables and such.
Just get the JDK from blackdown working and then download swing, set up your classpaths and your gold. (Swing is written completly in Java so getting platform implementation is not necessary, ah the beauty of java.)
Okay being curious I have listened to most of the episodes and this one was by far the worst.. perhaps you guys could come in to the show with a little bit of a plan.. It can still be adlib but this was really poor.. Something technical must have happened at the conference.. or at least discuss some issues.. Peeing in a cup is NOT funny, It may have been in high school (So I ask myself, prehaps I am just the wrong audience for this 'radio' show, this might be the problem.)
Try doing something a little more worth while.. The stories posted have substance. Let your radio show follow suit. Would you post a story, Hemos pees in cup! I think not.
Anyway, I will still listen to the next one.. Who knows you might read this and agree that a bit of planing might not be a bad thing.
Interesting I see this on Ask/. cause i was gonna submit the same question. We are currently in the process of setting up a web app for our clients and are trying to decide which db will run the app. We currently develop using postgres but the speed of MySQL is very attractive.
I have done as much research as Google could point me to and as far as i can see MySQL screams but it is not feature rich. Here is the summary of an afternoon (last week) of research (Disclaimer: I still have to do benchmarks myself but this is a start.) MySQL is fast but it lacks some important stuff that we decided we couldn't live with out.
Doesn't support inner selects - I tried to convince my self that I could live without these but today while doing some data cleaning i was using them all over the place.
no support for transactions, they suggest table locking but when you are updating several tables at once locking all of them maynot be the best thing to do. They are going to implement some sort of transaction process but rollbacks won't be incorporated.
Postgres on the other hand was developed in a very academic enviroment and is extremly feature rich. The major draw back to postgres I could see was that it doesn't scale very well and i am not sure if 6.5 addressed any of these issues. That being said if the db won't scale then it really doesn't matter how many features you have.
They guys who developed MySQL have a really cool and usfull tool on there web site that runs a script and lets you know exactly (It is VERY detailed) what features each db has.
I strongly suggest anyone insterested in benchmarking features of dbs check this out. db compare
We decided that we would use postgres until we do our own benchmarks. It may scale enough for what we need, the load shouldn't be too high for our use.
more info would be great, also the timeline for MySQL to incorporate inner selects would also be handy cause i know they havbe it at the tops of the features they are going to implement.
I always found X to be faster than Timbuktu... and other win stuff. I have never done any real tests but that was my impression. Could you expand further on the differences there..
There is a difference between bloatware and options..
Although many distro's are now adding third party software as part of their distribution, this is not bloatware of Linux. This is Linux trying to service many different types of end users.
prgrammers
regular users
power users
servers
workstations
(choose your use)
Such being the case, they include distribtuions that will allow the user to acomplish all of this with out having to go out and get more software. The base Linux OS is still relatively small, especially compared to Windows.
So if Suse wants to give there users an option of trying Vmware, so be it, if this does not suit your need you simply do not install it.
I do agree this is veering from the Free Software Movement that started this whole ball rolling, and if you are really concerned about having only Free Software on your computer then install Debian. (I know they have some un-free software in their tree but it is segregated in the non-free section.)
I have not tried SUSE, but i am assuming it is similar to RH and Debian in that it will allow you to select what you wouldlike installed.
I agree with the previous post about the debain package management being quite a bit more sophisticated(sp?). RPM seemed to cause me quite a bit of grief with failed dependedcies and stuff.. But with Debain i simply select the package i want and it will let me know what i am missing give me the choice to install it and then will configure it for me (to the best it can).
NOTE: I am using an ftp install for debian and am not sure if this was available for rpms so that it would preform the same.. either way
RH seems to be doing a wonderful job and the fact they keep hiring key guys is fine by me.. At least these guys get to work for a place that lets them do what they are good at so the rest of can benifit.
(if rpms do have the same features let me know. that would be swell)
I have also tried to talk to rational about porting there stuff to Linux and they are not into it at all! It should be fairly easy for them to port to another *nix as they have it runing on a bunch already..
Lets all mail rational and see if we can get them to port some of there products to Linux..
Here is the person I dealt with, send a polite email expressing your interest in their products and hoping they get ported to Linux. (If you are interested in there products.) Franco, Kathryn
I can't believe someone is still flogging Hurd. FreeBSD, OpenBSD, NetBSD, Linux, blah blah blah - who needs *another* OS?
I hope you were trolling when you wrote this. Without continued development in different directions by people with different needs Linux would not be around. Who knows a new better operating system might be jsut around the corner.. Oh but i forgot why would anyone use another OS what ever you use must be the best and we should all just use that and be happy.. Many of us are excitd to see Hurd and I don't mind people talking about different technologies. Some day i may have to use one of those technologies and if people didn't talk about them then I may never have know about them.
Lets encourage different OS's, editors, compliers; who knows we might end up with something we like. -7021
I have been using emacs for 5 years now and although it may be a bit large if you just use it for an editor, but many don't as explained before.
In fact I was on contract this summer and was asked to choose the IDE (Java was the implementation language) of my choice. The company had set aside 1G. After some heated discussions i broke down and agreed i would spend one week trying different IDE's on the market. I tried JBuilder, VisualAge, Cafe, and basically they all stunk.
I choose emacs with JDE cause it was by far the most powerful. While it is not for everyone (including Linus apparently) I consider it one of the most usefull programming tools i have, and to me Linux without emacs is only half as useful.
