OfflineBrowser
I don’t know when it will appear in the preware feed. If you want to test it, here is the ipk:
de.metaviewsoft.offlinebrowser_1.0.3_all.ipk (567,6 KiB, 229 hits)
Please check Preware for the latest updates of OfflineBrowser.
As some of you might already read on Twitter, I wrote little Offline Browser app which tries to fix some annoyance with the original browser and the whole workflow during reading Twitter, Email or RSS feeds:
* new browser card pops up in the foreground
* sometimes you get a gray browser card with blinking icon
* sometimes you get an orphaned browser window which doesn’t go fullscreen anymore
* sometimes the browser forgets what he has and you have to reload
* some pages are very slow thanks to css/js/files which the browser needs to load before displayingOffline Browser will try to help you to avoid these annoying things. By catching URLs, storing them in a database, downloading the html in the background and storing it in the database too, showing a preview without CSS and JS, but mostly working links.
Discuss it here: http://forums.precentral.net/webos-homebrew-apps/288067-new-app-offline-browser.html

Precaching for webOS
After the last changes on geocaching.com website, the nice app “Geocaching for webOS” doesn’t work anymore. The developer of this open source app isn’t available right now (in fact he hasn’t answered any question etc. since month).
I started to fix the app, as it is a nice companion to MapTool for getting geocaches around you.
I’m not that far yet, login works, but no cache search atm. Geocaching.com switched from GET-based search url to a completely POST-based system.
I put my current state here to give other the possibility to do further work.

MapTool Pro
Follow this link to download the latest version of MapTool Pro on your webOS device.
The main view is a map view with a top status layer and a bottom status layer and a standard command button menu on the very bottom.
The top status layer shows configurable values. The bottom status layer shows time of last fix, accuracy of last fix, current altitude (as reported from GPS), current elevation of ground (based on NASA data), current speed (as reported from GPS), current heading (as reported from GPS), track ID (if tracking is active) and current grid size of the displayed map.
There are 2 other views which you can access by swiping left or right on the touch area (also call forward and backward gesture).
The command button menu on the bottom gives you access to zoom in, map menu (tap on the current zoom number), zoom out, center and follow position, send current position or current track and tracking switch.
From the map menu you can access search, targets, tracks and the dashboard view which you also can access by forward gesture.
From the application menu (on the upper left corner of the screen) you can access the settings screen, a webpage with links for geotools, an option to open geocaching.com, a goto menu for manual entering coordinates, routing from your current position to your current target, cache area to download offline maps for your current position for certain zoom values, a refresh item, clear databases and an help item.
The settings are as follows:
Renderer: from which renderer to download prerendered map tiles
Coordinates: format to display and enter coordinates
Units: metric or imperial
Max. log error: every fix with an worse accuracy are not used for track display, calculations and export
Pos. update: interval to update and store current position
Elev. update: interval to query ground elevation from net
Draw Grid: draw the grid lines on map display
Force Email: exporting tracks or targets as (a couple of) emails instead of backend server use with local saving
Block Screen Timeout: screen stays on
Hide Greeting: hides popup window on start
Photos: Show geo-tagged photos from Flickr and Panoramio on the map: just a marker + name or a small or larger thumbnail
No Smart Caching: always retrieve map tiles from selected server, don’t cache them locally
Top Left: what to display in left part of upper status layer
Top Right: what to display in right part of upper status layer

Terminus on WebOS 2.1
Terminus should now be able to work on every 2.1 device. I’ve updated my previous article here. Please take attention to step 4.a which is the key for the none-working attempts. If you already have a none-working Terminus because of the wrong line endings, try the following:
1. set line endings in internals to ‘linux’ 
2. open the jailusers file again
3. go to the end of the line where the jail for terminus is defined
4. make a new newline
5. remove the previous newline, which is now the empty line beneath the Terminus line
6. save it
If you don’t want to mess around with your phone, you could also wait some short time. In the preware testing feeds there is already a working xterm package and soon there will be a working Terminus too (thanks to rwhitby).

Presenter for WebOS
Wouldn’t it be cool if you could just send the screen of your webos device to your desktop computer and view it on your monitor or show it on a video projector? Maybe you want present your next big thing a couple of customers? Well, you could install the emulator and show this, but maybe you want to integrate things which aren’t available on the emulator? Maybe you want to showcase multitouch or use the shaker? Well then presenter might help you.
It’s far from perfect, especially PDK apps aren’t always visible. Web apps sometimes aren’t complete, that’s why it’s more a prove of concept at the moment.
Presenter consists of 2 parts: an app on your WebOS smartphone and a java application on your desktop computer. As a java application it should run on Windows, Linux or Mac without problems.
The image you will see on your desktop has a kind of watermark at the moment. You will see the address of my website rolling over the screen. Soon I will submit the app to catalog and also have a paid version without watermark there. Until then you can find the package for your Pre and desktop server here:
Presenter for WebOS (147,5 KiB, 583 hits)
Server part for Presenter for WebOS (1,9 KiB, 684 hits)
Here are videos which show what you get:

Get shell access on your webos 2.1.0 device
If you are an experienced Linux user or just like to dig inside the core of your webos phone, you probably had a couple of advanced homebrew apps installed on your webos phone:
* Internalz for anything related with file activities (although an hex viewer is still missing)
* Terminal, Terminus or xterm for shell access directly on your phone
Terminal, Terminus and xterm are created/ported by the experienced members of the great webos-internals crew. Don’t forget to support their work with a kind donation.
In the early days of webos 2.x, none of them where available.
In the time between, Internalz reappeared in Preware and runs better then ever. Don’t forget to send a donation to JayCanuck!
xterm was fixed by rwhitby the founder of the webos-internals group. You can directly support his work by buying the Preware Homebrew Documentation
Terminal is using an undocumented plugin mechanism which obviously was changed in 2.x.
Terminus is a standard PDK app created with the WIDK and just like xterm can be fixed to run on webOS 2.x. Most of the following is based on a discussion with rwhitby on IRC and his findings described here.
1. Install Terminus on your phone
2. Run it once
3. Install Internalz
4. Open Internalz and enable “Master Mode” in the settings (last entry)
4a. Enable Linux lineendings in Internalz! It will not work without.
5. Use Internalz to open the file /var/palm/data/jailusers
6. find the line with terminus and change jail_game.conf to jail-native_palm.confjail_native-palm.conf (thx to AUDEMARS02 for the correction)
7. save the file
8. run Terminus and enjoy
I got different reports about this how-to. Chances are that it only works on a Pre2. If you follow it on your device, please leave a comment telling me which on which device you tried it and what the result is.
Even if it doesn’t work on your device, nothing will break. It’s just that Terminus still refuses to work correctly.
With step 4a it now works again on all devices.
And now something completely different:
I’m just creating a small app which allows you to present the screen of a Pre on a projector or any computer monitor. I used it to capture this little video:

Crimson Fields for WebOS Source Code
Nobody did request it, but anyway, before trying to fix the issues with campaign mode, I’m going to release the adjusted source code of Crimson Fields for WebOS version 1.2.1, based on the original source code from version 0.5.3.
Download it from http://www.metaviewsoft.de/crimson-0.5.zip
You need to install the current SDK/PDK for WebOS from HP/Palm. For easier debugging, I used Visual Studio to debug on my Windows computer.

Original Palm Pre auf WebOS 2.1 updaten
Hier wollte ich mal kurz beschreiben, was ich machen musste um meinen Palm Pre, gekauft im November 2009, auf das gerade veröffentlichte WebOS 2.1 upzudaten.
Als Vorbereitung sollte man dafĂŒr sorgen, das
1. Die WebOS-interne Datensicherung auf aktuellem Stand ist.
2. Mit Save/Restore aus dem Preware-Katalog die meisten Anwendungseinstellungen gesichert sind.
3. Ein Backup aller Anwendungen z.B. mit meinem kleinen Tool mybackup durchgefĂŒhrt wurde.
4. Die USB-Partition komplett auf dem Desktop-PC gesichert wurde.
Im weiteren beschreibe ich die Vorgehensweise auf meinem WindowsXP-System.
1) Die Benutzung von mybackup ist ein wenig tricky. Man kopiert sich die kleine Anwendung (aus dem Zip entpacken) auf das USB-Laufwerk des Pre. Dann braucht man einen Shellzugang zum Pre. Novaterm oder Putty auf localhost:5522 bei eingeschaltetem Developerzugang sollte funktionieren.
Zum Backup geht man einfach auf den Pre, wechselt ins Root-Verzeichnis “cd /” und gibt “/media/internal/mybackup” ein. Dann öffnet sich auf dem Pre eine PDK-Anwendung bei der man auf Backup tippt. Nun dauert es etwas und man kann in der Shell und auf dem Bildschirm verfolgen, was er alles einpackt.
Das Backup liegt dann im Ordner MyBackups auf der USB-Partition vom Pre.
Zum Restore muss man a) das Dateisystem schreibbar machen “mount -o rw,remount /”, ins Root-Verzeichnis wechseln “cd /” und dann “/media/internal/mybackup” aufrufen. Dann auf Restore und alle Anwendungen sollten wiederhergestellt werden.
2) WebOS Doctor herunterladen: Unter http://kb.palm.com/wps/portal/kb/na/pre/p100eww/o2/solutions/article/71380_de.html#21 bzw. http://palm.cdnetworks.net/rom/preplus/p210r0d02212011/eudep210rod/webosdoctorp101ueude-wr.jar
kann der WebOS-Doctor fĂŒr 2.1 heruntergeladen werden.
3) Cygwin installieren: Unter http://www.cygwin.com die install.exe herunterladen und dann mindestens die folgenden Pakete auswÀhlen:
1. Python
2. Make
3. Patch
4. Git
5. Zip
6. Unzip
7. wget
4) Den MetaDoctor von webos-internals herunterladen. Den MetaDoctor gibt es hier:
http://www.webos-internals.org/wiki/Application:MetaDoctor
Das Verzeichnis vom MetaDoctor am besten ins cygwin-Verzeichnis kopieren.
5) Den WebOS-Doktor in das Verzeichnis meta-doctor\downloads kopieren und in webosdoctorp100ueu-wr-1.4.5.jar umbennen.
6) Im MetaDoctor Verzeichnis das makefile mit einem Editor (Notepad++) öffnen.
6a) Wenn man unter Windows als Administrator arbeitet, kann es nötig sein, die Zeile 839 durch diese zu ersetzen:
${TAR} –no-same-owner -C build/${PATIENT}/webOS \
6b) Im oberen Teil der Datei die folgenden Optionen einschalten (# entfernen)
ENABLE_DEVELOPER_MODE = 1
AUTO_INSTALL_PREWARE = 1
REMOVE_CARRIER_CHECK = 1
REMOVE_MODEL_CHECK = 1
DEVICE = pre
CARRIER = wr
6c) Cygwin starten und in das Verzeichnis meta-doctor wechseln: “cd meta-doctor” und dort den MetaDoctor starten: “make”
7) Wenn der MetaDoctor fertig ist (das kann etwas dauern) ins Verzeichnis build gehen und den neuen WebOS-Doctor durch einen Doppelklick starten.
Siehe auch:
http://www.webos-internals.org/wiki/Application:MetaDoctor
http://www.webos-internals.org/wiki/Application:MetaDoctor#Using_Cygwin
Problem:
Ich konnte mich nicht wieder bei meinem Palm-Profil einloggen. Ich habe jetzt erstmal ein temporĂ€res Profil erstellt. Dank des Backups habe ich aber alle Apps auch auf meinem neuen System. Jetzt warte ich mal ab. Vielleicht gehe ich auch wieder zu 1.4.5 zurĂŒck, der Pre ist stellenweise doch deutlich zĂ€her geworden. DafĂŒr sind Features wie Just-Type einfach nur Klasse. SpĂ€testens, wenn Pal mir einen Entwicklungs-Pr2 schickt, werde ich den Pre wohl wieder auf 1.4.5 zurĂŒcksetzen, und dann den Pre2 als Entwicklungs- und HauptgerĂ€t verwenden.
