Not only robot

In this period the figure of Isaac Asimov is very present, for the laws of robotics. There is another book That I think is very timely: “The Nacked Sun”. In this book, in addition to being present robots with their problems, there is a world where humans communicate only look through a screen, trying to bother even to not stay in the same room with other people, because they do not want to breathe the same air. The same procreation is just artificial. Is it a science fiction book?

Are we all copies?

In these days i see a lot of peoples that want to think as Jobs or Gates or others, but these are originals because are themselves, no copy. I see a lot of books to think as Jobs or similar, with all the respect for Jobs, but i think that he is not the best mind of the world. Copernico, Galileo, Leonardo, Einstein, Turing, Tesla. Ritchie, were stupids? Don’t have they improved the world? Maybe we think what Genius does not require effort, but Edison told: “Genius is one percent inspiration, ninety-nine percent perspiration”, it is harder than reading a book.

Philosophy?

In these days we talk a lot of coding as the new critical thinking and as new literature. I want to go besides, perhaps with the coding you are back to the old science, That before the French Revolution (from That moment onwards Scientists have always Been More classified in sectoral almost confused with the “technical” disciplines). Prior to this  (the two World Conflicts completed this change) the Scientists were multidisciplinary, think of Galileo, Leonardo And Others; they were philosophers, inventors, hackers (curious) Today with the coding maybe we again individually purchasing this multidisciplinarity,  Returning to take care of the diversity of Humanity aspects (the software must Solve a Problem (reduced to mathematical formulas – pure coding) but must interface with Being Human (psychology visual, emotional, etc.), dropped in the context (sociology.) What the machines push us to rediscover humanity That we were losing?

OpenSuse Leap 42.1 Nvidia failure after update

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.

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

v-play on opensuse 12.3

To install v-play game engine on opensuse 12.3:

 

  1. zypper install mesa-libgl-dev
  2. zypper addrepo http://download.opensuse.org/repositories/games/openSUSE_12.3/x86_64/ opensuse-games-x64
  3. 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

Mobile Autologin Pattern

I’m thinking if is usefull to use autologin pattern for mobile application. If i have a application that has need of authentication, is correct to give to user  the possibility of auto login and to give to user  the possibility to disable this function ?
A browser that remembers authentication info isn’t more secure (for me).

Alice on SailfishOS

I ported my application “Alice” 0.1 (from BB10) to SailfishOS. The application is used to check the status of growth of children. Obviously, the execution Screenshots have taken on the emulator. The porting was fairly simple. One thing that  has misled me is that BB10 uses  selectedIndex for groupbox instead sailfish use currentIndex. To be an alpha version seems like a good start.

Portable Body

Martin Fowler talk in this article (“http://www.martinfowler.com/articles/mobileImplStrategy.html” )of portable body (slide 23). He talk thinking a web, i instead think to Qt/Qml, where Qml is the native gui and c++/javascript is the portable body. Is exsisting a benchmark between qml/Qt vs Hybrid(web+native; javascript+native) applications? For me this is an interesting point. If someone wants to help me in this comparison, I would be happy.
