Re: Making Javascript Application embedded in a small gtk window.
I paid good money for this cool little nokia tablet and will run whatever I can get to run on it. Javascript has a bad rap as an ugly thing used for annoying popups. It's gotten much better, especially when using APIs like dojo and jquery. If it helps: Android, iPhone, and blackberry developers can use the opensource Phonegap ( http://phonegap.com ) . It creates apps that are simply wrappers for the web browser but with a common javascript API to use the location, acclerometers, vibration, etc. Would be nice to see a maemo port of phonegap.

And remember that ARM has zero interest in helping the maemo project utilize those CPU extensions. Simply purchasing the hardware is not good enough for them.

Re: web based local application GUIs
local search will not talk to the GPS unit connected to a 770,800,or 810. You can go to local.google.com and put in a location, then do something like search for the nearest pizza point. Works great. Also some windows mobile and j2me phones/PDAs can download a google maps app that talks to the gps device. But what I'm talking about is a standard that any website can use automatically by embedding something like
Re: web based local application GUIs
Meanwhile, Microsoft teamed with Sprint 3 months ago to provide web applications that are location aware: http://www2.sprint.com/mr/news_dtl.do?id=18020 The same sort of thing is attainable on an N810 using open standards when the connection is live, but the point still stands that the local service should be available offline.

Re: web based local application GUIs
How about a GPS daemon similar to gpsd but with the capabiltiy to speak HTTP? Would be nice if people making webapps could include a javascript source from the localhost that would give back an object with GPS info. I've already written very lightweight implementations of this in Java and Python, however both rely on gpsd. I'm guessing one for the n810 could just call to the GPS APIs. I'm sure there will be security concerns, but it should be easy to turn off and on, and wouldn't be a big deal for a mobile device. The daemon also doesn't need to give a highly accurate latitude and longitude to still be very useful. Luis Zoran Kolic <[EMAIL PROTECTED]> wrote: > > 1.) Rpc (aka web services) > > 2.) Dbus > > 3.)

Re: [maemo-developers] Status of Java on the N770 ??
There isn't an open source J2ME implementation out there. I'm currently trying to implement one but could use a bit of help :) I think a derivative of GNU Classpath and jamvm could work. The archives on this list show that jamvm/classpath(J2SE) can be compiled for the device, but there are some GTK bindings problems. Once fixed, it may still not be practical given the limited hardware on the 770. The J2ME CLDC 1.1 and MIDP 1.0 specs are pretty small. I think it would be nice to implelment CLDC1.1 as a subset of classpath .20, and the MIDP1.0(or the much larger MIDP 2.0) as jni calls to GTK/Hildon. Once that is complete, jbluez or a bluetooth package on top of javax.comm(rxtx's implementation) could be added to support JSR82. I know the screen is larger than what most J2ME targets are, but there is no reason we can't use all the pixels in new development, or do some kind of zooming on older Midlets. Nokia could also give us a hand by replacing the jamvm component with something of their's that could use the ARM Jazelle extensions to really speed up java on the device. Having j2me on the device would instantly get us hundreds more applications and games. It would also open it up for cross-platform development and other IDE's like eclipse. thoughts? -Luis > > From: Fabrice DI MEGLIO <[EMAIL PROTECTED]> > Date: 2006/02/01 Wed PM 07:05:13 EST > To: maemo-developers@maemo.org > CC: maemo-users@maemo.org, Fabrice DI MEGLIO <[EMAIL PROTECTED]> > Subject: [maemo-developers] Status of Java on the N770 ?? > > Hi, > > I have just bought a nice 770 a couple of days ago and would like to > develop / port some Java applications on it (as probably some other > developers). > > My first experiments with finding something usable has been not very > successful: > > - blackdown Java 1.3.1 for ARM processor does not seems to install nor > run correctly > - jamvm seems to start but is very restricted due to current GNU > classpath implementation and does not provide any JIT. > > So could I get a status, infos and your experience about Java running on > the 770 ?? > > Unfortunately, if it is not possible today I will probably need to give > it back :-(( > > Best, > > Fabrice > > PS1: yes , I have already installed scratchbox and looked at the C/C++ > way of developing application for it but I really need running Java. > > PS2: sure it would be great to run a Java VM CDC 1.1 with Personal > Profile on it ;-)) > ___ > maemo-developers mailing list > maemo-developers@maemo.org > https://maemo.org/mailman/listinfo/maemo-developers > ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
[maemo-developers] Java Question for the Nokia guys.
Not sure if this is the right place to ask, but I've seen some emails on this list from people with @nokia.com addresses. I've read the archives, and so far don't see anything conclusive with regards to a working java implementation J2ME or J2SE. I noticed a post in the archives about this output from /proc/cpuinfo Processor : ARM926EJ-Sid(wb) rev 3 (v5l) BogoMIPS: 125.03 Features: swp half thumb fastmult edsp java CPU implementer : 0x41 CPU architecture: 5TEJ CPU variant : 0x0 CPU part: 0x926 CPU revision: 3 Cache type : write-back Cache clean : cp15 c7 ops Cache lockdown : format C Cache format: Harvard I size : 32768 I assoc : 4 I line length : 32 I sets : 256 D size : 16384 D assoc : 4 D line length : 32 D sets : 128 Hardware: Generic OMAP1510/1610/1710 Revision: 17100016 Serial : 033302008b5f702f Does the Features line mean the 770's ARM chip has the potential for hardware acceleration for java? If that's the case is Nokia working on a JVM for the device? I like writing applications more than hacking at JVMs, so I don't want to spend too much time doing hildon specific bindings or trying to get a slim enough version of gnuclasspath and kaffe/gcj/jamvm working efficiently.
