Correzione

Nel numero di Novembre "La mia storia",
di Jesee Avilés, lui ha commesso un terribile errore.
QGIS (qui sotto)
è un Sistema di Informazione Geografico, non un'applicazione CAD 2D.
Sebbene per molti potrebbe essere lo stesso, essi sono radicalmente differenti.
In un GIS potete creare,memorizzare e visualizzare dati in una varietà di sistemi di coordinate.
Alcuni potrebbero sostenere che un CAD può manipolare dati che essenzialmente hanno un sistema di coordinate.
Questo è in parte vero dato che per esempio un sistema CAD non sa come manipolare dati di zone UTM contigue.
Un'altra differenza è che il dato in un GIS ha una tabella attributi che vi permette di utilizzare in molti modi differenti i vostri dati. Le differenze potrebbero continuare a lungo, il mio punto di vista è che dovete controllare più a fondo questi tipi di articoli.
Personalmente lavoro in ambiente Windows, ma utilizzo Ubuntu per alcuni progetti speciali.
Uso QGIS per introdurre i miei studenti (B.A. in Archeology) alla cartografia e alla cartografia digitale.
QGIS è multipiattaforma, mi permette di espandere il mio pubblico (molti dei miei studenti utilizzano Mac o alcuni sono a favore di Linux) ed è open source, non esistono problemi con la violazione del DRM.

MORE CLI!

n FCM42, Chris Burmajster
pleads for "even less CLI".
Though on first sight one
might agree with this, I really
do sympathise with this, but when
you consider this more closely this
is not what we want. A GUI can only
scratch the surface of the most
often used capabilities of Linux. If
we want to put all the capability of
Linux, in a GUI, that GUI would get
so big and complicated, that no one
would be able to find even the
most common button to
accomplish anything. So his plea for
a "simple GUI in which one can do
anything" is just completely
impossible. Sorry about that.
"manual" (handbook on the hard
disk), and is also a command. If one
chooses not to use the CLI, then
just don't use it, but please do not
ask for a magnificent OS as Linux to
be Window0ized from its real
power.
Jaap Woldringh
If people move from Windows
to Ubuntu, the advantage they get
first is a safe and more reliable
system, in which most things they
want to do can be done using the
GUI, which is simple, I do agree with
that. The real strength of Linux is in
the command line, and anyone who
can use a keyboard to type some
characters can profit from even the
most simple commands, of which it
is not really necessary to learn that
many. There is nothing complicated
in using simple commands such as
cd, ls, mv, cp, except for a
psychological barrier maybe. The
power is that one can vary these
commands in many tens or
hundreds of ways, and that is
daunting if you want to know them
all, which no one does, or needs to.
One can use 'man' to know all that
one needs. Man is short for
22
More Backup Ideas,
Less Excuses
All the highlighted backup
solutions Mr. Mins offered [in
FCM#43] are very good. Dropbox
and Clonezilla are especially good
tools. Unless you are limited to one
desktop device, there are other
options as well. My Linux gateway
box is provisioned with an extra
hard drive just for backups. Under
that scenario you then have two
additional options:
* Rsync 0 an old stalwart that 'just
works' when a little configuration is
applied to it.
* Unison 0 my tool of choice when it
comes to data syncing. One of its

John McGinnis
just read FCM#43, and in the
"Backup Ideas" it really missed
spideroak:
http://www.spideroak.com.
It has great Ubuntu (and other
Linux) support, and the client is
very configurable. They also have a
zero0knowledge approach, meaning
that the Spideroak company and
employees cannot find your
password or decrypt your data.
That gives me real peace of mind.
I am sorry that I don't have time
to write a review myself 0 but
please take a look. The 2GB
accounts are free, and if you want
more data there is 100GB for 100
USD.

noticed the answer to this
question:
Why doesn't the command: ls |
grep *zip do what I want?
and wanted to provide an alternate
reply: The reason is that * means
that the preceding character
repeats 0 or more times and you
haven't specified a character, so it
returns empty. The solutions are:
