[SailfishDevel] Battery life without The other half Daemon running
Hi everybody, I read this article today: http://reviewjolla.blogspot.com/2013/12/jolla-battery-life-power-consumption.html And now I trying to measure the difference with tohd on and off. I am using powertop to get the amount of power consumed by the phone. - With tohd on, wlan on, screen off, logged in via SSH - 982mW - With tohd off, wlan on, screen off, logged in via SSH - 552mW This is a great difference I think.

Re: [SailfishDevel] QtContacts available
Hi Marko Thanks, that has deepened my understanding, and confirms what I had guessed / inferred. I will update my blog later with a simplified version of your explanation.

Once you SSH in, zypper is available, but if you zypper at that level, all you are doing is adding stuff to the operating system. Within this VM is SB2, which is the Build Engine itself. Others on this mailist are much better qualified than me to tell you more about it. If you are familiar with the term chroot (change-root) then you could thing of SB2 (Scratchbox2) just as an chroot environment running armv7hl emulated code (through qemu) where you actually build your source rpm package. SB2 comes from the legacy of cross-compiling. The problem with cross-compiling is that you need to tell your compiler not to use the host (x86) tools and libs for compiling but the equivalent tools and libs from the target (armv7hl) system. There are multiple approaches to overcome that. One is to tell the compiler (via e.g. configure, makefile,...) where to find that stuff or you don't tell the compiler that (less work to create a makefile that cross-compiles too) but alter your environment that the compiler thinks it is running on the target (armv7hl) system itself. This is what SB2 actually does. That is very useful if you want to compile just any normal rpm package (from the linux userland stack) without adapting it to the target architecture. (In detail SB2 is not a full chroot system, but it uses fakeroot which enables SB2 to use host tools for speed up compilation instead of running arm binaries in slow emulation mode. It's quite some time ago I used SB2 but I hope I got it right and you got a rough idea... :) Cheers, Marko ___ SailfishOS.org Devel mailing list ___ SailfishOS.org Devel mailing list

Hello,
I also wanted to use a Map in my application, and I am still struggling.
I already figured out that:
- We have to install QtLocation/QtPositioning in the SDK
- We have to manually install them in the emulator (I just found out about
pkcon and zypper)
- We need to use QtPositioning.coordinate instead of Coordinate.
But now, if I try to display the simplest Map, I just get a blank screen. I
have a message telling me that there is an error with the Plugin I use (does

Re: [SailfishDevel] python development
2013/12/19 David Jensen davidjen...@usa.net: Nokia's original book on Meego featured, I think, Python as the development. I do not see this book on Amazon. However, almost none of the articles I have seen relating to Jolla mention Python. I assumed Nokia believed Python was an ideal language for an open system that was easily modifiable by others. I get the impression the language is C++. This is more difficult than Java and possibly also Objective C. How does Jolla expect their system to be adapted as open if the language developers have to deal with is C++, with Python a vague afterthought? Python 3 and a QML Plugin that can be used to call Python code from QML will be available soon in the repositories, we're testing integration and making sure everything works and the API is stable. We use Python 3 instead of Python 2, because Python 2 is going away soon[1]. With that said, the language for native Sailfish user interfaces is QML, which has a built-in JavaScript engine, and support for JavaScript expressions and blocks. You can do native development with QML and JavaScript alone, or go with the C++/QML/JS or QML/JS/Python combo. There's nothing stopping you from linking against any other dynamic language, you just have to write the binding / data passing between QML (the UI layer) and your favorite language manually (in C/C++).

I've added it to the list of libs to be considered. Let's see... Do you think it likely that some python libraries are likely to be considered too? At the moment, I think the best way is to ship any additional Python libraries you need with your app (install somewhere below /usr/share/$APPNAME/). I think it's much work to start pulling in Python libraries into the repositories and difficult to maintain them there. Because of the dynamic nature of Python, it's even harder to verify apps don't break with OS/library updates compared to native C/C++ libraries (where one could at least do a static check for exported symbols, etc..). Just providing the standard library as shipped with Python 3 is relatively easy to maintain, and apps can then ship different versions of modules they need. We can of course provide some guidelines for how to best package/bundle Python libraries (especially more complicated ones that involve C extension modules) into an application's RPM package, and make sure the bundling/packaging experience is as good as possible.

[SailfishDevel] Booting from SD card
Ahoy, Is it possible to boot a rescue system/second os from an sd card with the Jolla phone? I have not yet found good documentation for this. Cheers, Oliver ___ SailfishOS.org Devel mailing list

Thanks for asking this, Winfried ;) I am developing an app that uses QSettings to manage app-spesific configuration and that handless nicely the persistence of settings in default file-system locations. Now, it would be perfect tp expose those settings to system Settings GUI.

This is understandable - having Python available at all is fantastic. We can of course provide some guidelines for how to best package/bundle Python libraries (especially more complicated ones that involve C extension modules) into an application's RPM package, and make sure the bundling/packaging experience is as good as possible. Any guides would be very welcome, as I come from a python and web development background. Packaging is something I don't have much experience at. I've started making some general Sailfish Python Development notes on the Mer wiki: https://wiki.merproject.org/wiki/Sailfish/Python_Development Thanks again!
