Today (in the morning) i have updated my Suse, after the reboot instead of the graphical login appears a X11 black screen. With CTRL+ALT+F1 i can log in textual mode and see the output of dmesg, seems that not all the NVIDIA packages are updated to the latest version. I found this solution (i hope it can to be useful for other user that have this problem), reinstall all NVIDIA packages already installed. After the reboot i had graphical login.
The UX as humanity
The UX as humanity, as attention to another. I’m thinking these days, thinking about the first meeting of idf benevento. I often think (or we think) to have a good UX to create a winning product. Thinking well, however, to create a good UX means having care for each other, put aside their own beliefs, their own patterns and step into the shoes of the other. The more we are good at doing that, the more we are good to have this empathy with each other, the more the UX will be better. So UX is humanity.
UX not always is cool
One of my hobbies is to develop educational software for children. In this moment in history, app. When using a new medium is always tempting to use anything that is new, but it is not always a good thing.
In a software in multiple choice, a teacher told me: “use the drag & drop not use the click on the buttons, it’s a tablet is not a PC.”
I was silent, I asked the children to choose trying the two solutions, answer: “is the most menial click, we want the buttons.” (Now the teacher is silent)
It is not always what’s cool is usable. From my experience use the drag & drop when you have a multi choice with multiple answers (see figure).
Qt5.3.1 and IOS
If you have developed for ios with a previous version of Qt, after that you open your project the buttons build and run can to be ghost. In this case i suggest to close QtCreator, to open xcode and run a project.After to close xcode, and run QtCreator. Now should to be all ok. Good work
Play Sound on IOS with Qt App
I wrote this page http://qt-project.org/wiki/IOS_SOUND__IMAGE where i explain how play sound file with a Qt app on IOS. I invite you to look carefully into the. Pro file of the example, to point out the differences with a default pro.
LeapMotion Game
In this video i shown a simple game to learn the colors names (in italian). I used Qt 5.1.1, LeapMotionSDK Leap_Developer_Kit_0.8.0_5300_Linux on OpenSuse 12.3. The code is of 50 C++ LOC and 150 QML LOC.
is it new or old UX?
I waited for the Leap Motion for 8 months. Finally today I tried it, I have to say I think it is fun and also useful in certain activities, not only educational and fun.
This type of interface opens new scenarios, to date the GUI for PC take their cue from the real world as windows, drawers and disfigures them in the virtual world, the drawer of my bedside table does not open by double clicking above, as I do not make the window disappear by pressing a button. I wonder if the leapmotion, (and similar devices that will be), with the new (in the virtual world) way of interaction, which is closer to those we use in the physical world, does not lead to rethink user interfaces and the user experience more modeled on the physical world (in case opening a directory pulling and not pressing).
SailPI = Sailfish + RaspberryPi
I’m developing simple application with SailfishOS to control the GPIO pins of the raspberry (must to be running webiopi on the raspberry). Running this application in the emulator i can turn on/off led and other things.
v-play on opensuse 12.3
To install v-play game engine on opensuse 12.3:
- zypper install mesa-libgl-dev
- zypper addrepo http://download.opensuse.org/repositories/games/openSUSE_12.3/x86_64/ opensuse-games-x64
- zypper install libglfw-devel freeglut-devel libzip-devel
This step is only to resolve installation dependencies.You’ll probably have to change something to compile. Stay tuned
arduino and opensuse 12.3
I modified the arduino yast files for opensuse 12.3
