just upgraded to fedora 25

Δευτέρα 12 Δεκεμβρίου 2017

Η έκδοση που χρησιμοποιούσα, η 23, δε θα ενημερώνεται πλέον μετά την 20/12/2016.

Χρειάζεται οπωσδήποτε το dnf-plugin-system-upgrade
Οπότε, αν δεν το εχουμε, το εγκαθιστούμε με την εντολή

$ sudo dnf install dnf-plugin-system-upgrade

Η αναβάθμιση από το 23 στο 25 [δεν είχα κάνει αναβάθμιση στο 24]
Έγινε με μόνο τρεις εντολές στο τερματικό

1] ενημέρωση
$ sudo dnf upgrade --refresh

2] Κατέβασμα των αρχείων της νεας έκδοσης Fedora 25
$ sudo dnf system-upgrade download --allowerasing --releasever=25

3] Επανεκίνηση και αυτόματη εγκατάσταση, καθάρισμα άχρηστων πακέτων λογισμικού κλπ.
$ sudo dnf system-upgrade reboot

[σε κάποια στιγμή με ρώτησε απλώς αν θέλω τα “κλειδιά” και απάντησα y [=yes]]

Ολόκληρη η διαδικασία πήρε τρεις ώρες.

The Ubuntu team is pleased to announce the release of Ubuntu 14.04.5 LTS

As usual, this point release includes many updates, and updated
installation media has been provided so that fewer updates will need to
be downloaded after installation.  These include security updates and
corrections for other high-impact bugs, with a focus on maintaining
stability and compatibility with Ubuntu 14.04 LTS.

Mythbuntu 14.04.5 LTS, Ubuntu GNOME 14.04.5 LTS, Lubuntu 14.04.5 LTS,
Ubuntu Kylin 14.04.5 LTS, and Ubuntu Studio 14.04.5 LTS are also now
available. More details can be found in their individual release notes:

Maintenance updates will be provided for 5 years for Ubuntu Desktop,
Ubuntu Server, Ubuntu Cloud, Ubuntu Core, Ubuntu Kylin, Edubuntu, and
Kubuntu.  All the remaining flavours will be supported for 3 years.

First use of VOICE TYPING in a Google Document

The service can be used only in Google Chromium.
You open a Google Document and you click
voice typing
then you choose the language ( I prefer US English)
and you click the microphone icon.
It works pretty well if you have a good microphone,
I personally used an external one.

The short text I dictated was from GEORGE ORWELL's book,
"Animal Farm".

Mr. Jones common of the manor Farm, had locked the henhouses for the night, but I was too drunk to remember this to shut the pump house. With a ring of light from his Lantern dancing
from side to side, he lost across the yard taking off his boots at the back door, Drew himself

a last glass of beer from the bottle in the gallery, and made his way up to bed, when mrs.
Jones was already snoring.

As soon as the light in the bedroom went out there was a stirring and a fluttering all through the farm buildings. Word had gone around during the day at all major commands the prize medal Wine Bar, have had a strange dream on the previous night and wished to

communicate it to the other animals. It had been agreed that they should all meet in the Big Barn as soon as mr. Jones was safely out of the way. Of major (so he was always cold
coming through so the name under which he could being exhibited was Willingdon. But I just
was so highly regarded on the farm but everyone was quite ready to lose an hour sleep in order to hear what he had to say.

At the end of The Big Barn, on a sort of raised platform, major was already ensconced on his
bed of straw, under the lantern which hung from a beam. He was 12 years old and had lately grown rather Stout but he was still a majestic looking bigger, with them a Wise and
benevolent appearance in spite of the fact that his touches have never being cut. Before
long the other animals began to arrive and make themselves comfortable under their different Fashions. First game the three dogs, Blue Bell, Jessie, and picture and then the
picture will settle down in the scroll immediately in front of the platform. The hens first

themselves on the windowsills, the pigeons flattered up to the rafters, the sheep and cows
lay down behind the pigs and began to chew the cud. The to cart horses, boxer and clover,
came in to get them walking very slowly and setting down their vast Harry who's with great

The words in red contain a spelling error, or are completely wrong.
The words in blue are the ones that the service SHOULD HAVE TYPED INSTEAD.
As I'm a non-native speaker of English, I suppose I've mispronounced a few.

The service isn't flawless, but it looked like a miracle to me!
I sort of felt like, Scotty, on the spaceship Enterprise, dictating to my computer!
Watch him trying to dictate to a pre-voice typing one
on youtube!

There are a lot of extra things  you can do with the text (e.g edit your text), apart from dictating
that you can see here:
