Ho creato questa applicazione ispirandomi a Il Libro Ritrovato di Richard Bach.

Il famoso scrittore, autore de Il gabbiano Jonathan Livingston e Illusioniha creato questo libro delle risposte per trovare soluzioni, o almeno suggerimenti, ai dubbi che ci assaltano continuamente, siano essi esistenziali o del momento. 

Il libro raccoglie, uno per pagina, aforismi, profezie, proverbi, massime.

L'autore ci invita a chiudere gli occhi, pensare a una questione della nostra vita che dobbiamo risolvere, aprire a caso il libro e leggere la frase che ci appare davanti agli occhi, applicandola al problema che ci sta a cuore.

Allo stesso modo, pensate intensamente a una domanda. Ora chiudete gli occhi e aggiornate la pagina facendo click qui...

Tutte le distribuzioni hanno un file di configurazione della rete, ma il formato e il posto in cui risiedono è differente. Modificare direttamente i file di configurazione può essere impegnativo, quindi ogni distribuzione mette a disposizione anche l'interfaccia grafico per effettuare la configurazione specifica.

L'utility Network Manager uniforma tutte le distribuzioni. Elenca tutte le reti disponibili (wired, wireless e mobile broadband), ne permette la scelta, getisce le password, e permette la configurazione di una VPN (Virtual Private Network).  

 

Collegamenti Wired e Wireless

I collegamenti di tipo wired non richiedono generalmente particolari configurazioni. L'interfazzia hardware e la presenza del segnale sono avvertiti automaticamente e il Network Manager  configura la rete grazie al DHCP (Dynamic Host Control Protocol).

Per configurazioni statiche che non utilizzano il DHCP il Network Manager fa ugualmente una configurazione manuale. Si può anche modificare il MAC address (Ethernet Media Access Control) se l'hardware lo permette. Le reti  wireless non sono collegate di default. Si può vedere l'elenco delle reti disponibili sempre utilizzando il Network Manager.  

 

Gli ambienti desktop più popolari sono GNOME, KDE (default di SUSE), Unity (da Ubuntu, basato su GNOME), Xfce, e LXDE. Molti desktop environment seguono la struttura di GNOME.

 

GUI Startup

Quando si installa un ambiente desktop il display manager X si attiva al termine del processo di boot. Il display manager X permette l'attivazione del sistema grafico. Quando si fa il login si può scegliere fra dispasati ambienti desktop disponibili. 

Il display manager di default per GNOME è chiamato gdm. Altri sono lightdm (utilizzato in Ubuntu) e kdm (associato con KDE).

 

Questo è un estratto del capitolo 3 Webcam and Video Wizardry del libro Raspberry Pi for Secret Agents di Stefan Sjogelid.

Attenzione: nel capitolo precedente abbiamo cambiato il parametro dwc_otg.speed in /boot/cmdline.txt settandolo a 1
per migliorare la qualità audio. Ritorniamo ad impostarla a 0. 

Questo capitolo utilizza una webcam USB anziché la Camera Pi. 

Ci sono due importanti componenti di Linux per gestire la camera:

 

Linux USB Video Class (UVC): sono i driver per far funzionare la videocamera

Video4Linux (V4L): è un framework utilizzato dalle applicazioni che registrano video dalle webcam, TV e altri dispositivi. C'è una versione aggiornata V4L2. 

 

 

 

Watch at least 20 minutes per day of video in English. You can watch clips on the internet or DVDs. If you watch a 10 minute video twice, that is 20 minutes! If you watch a 5 minute video 4 times, that counts as 20 minutes. I encourage you to experiment with your watching techniques: with subtitles in English, without subtitles, films you have already seen, rewinding, re-watching, turning on the subtitles, turning them off, etc.

Make a note of what you watched and any of your reactions or reflections.

  • Summary:

    the English coffeehouse was crucial to the development and spread of one of the great intellectual flowerings of the last 500 years, what we now call the Enlightenment. In fact, one important cause of the Enlightenment was the  switching from the previous use and abuse of alcohol - people was used to drink alcohol every time, because drink water was unsafe - to the inclination to coffee and tea (stimulant instead that depressant like alcohol). Furthermore, coffeehouses were important because of their architecture. A coffeehouse was a space where people would get together from different backgrounds, different fields of expertise, and share. Ideas got together there.  An idea is a new network of neurons firing in sync with each other inside your brain. It's a new configuration that has never formed before.
