Install Lightworks 15 on Ubuntu 17.10

Posted by MD     Category: Informatica

Hi, the Lightworks video editing program on the official website has two versions: 14 and 15,
now on ubuntu 17.10 for the 14 there are tricks to do to make it work and find various guides googolando, while instead the version 15 is designed for ubuntu 18.04 and 18.10.
Trying alone I found this solution that I share with you:
1) go to the official website https://www.lwks.com login or register

2) download the beta version
3) open a terminal (ctrl + t) and write to us
sudo apt-get install libcurl4-openssl-dev
give and send the password even if you can not see it and send it again
4) assuming that you have downloaded Lightworks-145RC4-105935-14.5.0.0.deb in the download folder we give in the terminal
cd Download

dpkg-deb –extract Lightworks-145RC4-105935-14.5.0.0.deb estrazione-deb
dpkg-deb -e Lightworks-145RC4-105935-14.5.0.0.deb estrazione-deb/DEBIAN
5) DO NOT CLOSE THE TERMINAL; now let’s go with the file manager in the Downloads / extraction-deb / DEBIAN folder and open the file controll,
now let’s replace libcurl4 with libcurl4-openssl-dev
save the file and close
6) we return to the already opened terminal and we give
dpkg-deb -b estrazione-deb
sudo dpkg -i estrazione-deb.deb

7) now in the main ubuntu menu we search and start Lightworks
here we enter our login data as in the site! #END

Good video editing

Rename PDF based on the title tag data

Posted by MD     Category: Informatica



Hello,
after several attempts I present a new script for Nautilus (file manager present in most linux distributions): allows you to rename all the PDF files, within the same folder, according to the internal tag of the title (for instance right click, property, document, title); very useful in various cases !!!
first of all download this file:

move the file to
/home/YourName/.local/share/nautilus/scripts/
then by right clicking on the file
go to property > permissions
and put the check mark on “Allow file execution as a program”
Now just select the file or pdf files that interest you and right click
script > renam-Port-title-tag-in-name.sh
NB: ATTENTION the script renames all the PDFs contained in that folder
NB: ATTENTION If the PDF file has no title tag the PDF will be deleted
I hope you come back useful !!!

View mp4 videos in ubuntu 17.10 gnome+nvidia

Posted by MD     Category: Informatica





Hello everyone,

after several searches on the web I did not find a working solution to see the video mp4 with H.264 encoding on Video (default program Video, internal name Totem).

The MPEG-4 AAC sound was heard but the video was not displayed!

In fact, if you open a terminal and write

totem namevideo.mp4

we will find a mistake like this:
libva error,driver_name=(null)

This happens above all with those who have the double graphic card in optimus intel + nvidia managed by prime

Premise: guide for those with ubuntu 17.10 (with new gnome shell interface 3.26 and later) and nvidia proprietary drivers and then xorg graphics server

Resolution:

I open a terminal (ctrl + alt + t) and copy and paste the following lines

rm ~/.cache/gstreamer-1.0/*

sudo apt-get install libde265-0 libgstreamer-plugins-bad1.0-dev libde265-dev libavcodec-dev libavformat-dev libdvdnav4 libdvdread4 gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly libdvd-pkg ubuntu-restricted-extras

sudo apt install vainfo vdpau-va-driver libvdpau-va-gl1

sudo chgrp video /dev/dri -R
sudo chmod 666 /dev/dri/*
sudo chmod 755 /dev/dri
sudo usermod -a -G video username

change username with your login name

NB: in these operations you will delete nvidia-libopencl1-384, accept changes when requested

Now DO NOT immediately open a video to see, you must first reboot the system completely !!

Once reopened you will have mp4 videos that can be viewed;)

Fix Microsoft font problem on Ubuntu 17.10

Posted by MD     Category: Informatica





The problem jumps out as an unsuccessful update called ttf-mscorefonts-installer ie fonts (fonts) used by Microsoft, it is better to install them to have compatibility on World documents in Libre Office.
Returning to the problem here is how to solve the problem on the fly without long tricks:
Let’s open a terminal with ctrl + alt + t or by looking it up in the main menu and make the copy paste of

sudo sed -i ‘s#http://downloads.sourceforge.net/corefonts#https://github.com/pushcx/corefonts/raw/master#g’ /usr/share/package-data-downloads/ttf-mscorefonts-installer
sudo /usr/lib/update-notifier/package-data-downloader

Obviously put your password when requested even if you do not see the typing of the same !!
Simple, no?

Hello everybody

Install Adobe AIR in Ubuntu 17.04 at 64 bit

Posted by MD     Category: Informatica



Since I needed a program made in AIR, I had to work to find the way to install it on version 17.04 amd64.
First of all, you will need the installable dependencies by opening a terminal (ctrl + t) and copying:

sudo apt-get install libgtk2.0-0:i386 libstdc++6:i386 libxml2:i386 libxslt1.1:i386 libcanberra-gtk-module:i386 gtk2-engines-murrine:i386 libqt4-qt3support:i386 libgnome-keyring0:i386 libnss-mdns:i386 libnss3:i386 libxaw7 libnss3:i386 libnss-mdns:i386 libxt6:i386 libnspr4:i386

Now you have to create symbolic links for proper functioning:

sudo ln -s /usr/lib/i386-linux-gnu/libgnome-keyring.so.0 /usr/lib/libgnome-keyring.so.0
sudo ln -s /usr/lib/i386-linux-gnu/libgnome-keyring.so.0.2.0 /usr/lib/libgnome-keyring.so.0.2.0

We now download a part of the program:

cd ~/Download
wget http://airdownload.adobe.com/air/lin/download/2.6/AdobeAIRSDK.tbz2
sudo mkdir /opt/adobe-air-sdk
sudo tar jxf AdobeAIRSDK.tbz2 -C /opt/adobe-air-sdk

We download the AIR SDK

wget https://aur.archlinux.org/cgit/aur.git/snapshot/adobe-air.tar.gz
sudo tar xvf adobe-air.tar.gz -C /opt/adobe-air-sdk
sudo chmod +x /opt/adobe-air-sdk/adobe-air/adobe-air

Now we are in place, now I’ll explain how to install any program with * .air extension
Obviously replace “NomePacchettoProgramma”(ProgramPartyName) end “NomeProgramma”(ProgramName) according to your needs !!

sudo mkdir /opt/adobe-air-sdk/NomeProgramma
sudo cp NomePacchettoProgramma.air /opt/adobe-air-sdk/NomeProgramma/
sudo mkdir /tmp/air
sudo cp NomePacchettoProgramma.air /tmp/air
cd /tmp/air
unzip /tmp/air/NomePacchettoProgramma.air
sudo cp /tmp/air /opt/adobe-air-sdk/NomeProgramma

Now let’s create a pitcher for the main menu (also replace “NomeEseguibile”(exec) and “iconaProgramma”(icon))

sudo su
cat << _EOF_ > /usr/share/applications/NomeProgramma.desktop
[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
Exec=/opt/adobe-air-sdk/adobe-air/adobe-air /opt/adobe-air-sdk/NomeProgramma/NomeEseguibile.air
Icon=/opt/adobe-air-sdk/NomeProgramma/iconaProgramma.png
Terminal=false
Name=NomeProgramma
Comment= quello che vuoi
Categories=Application;Education;Development;ComputerScience;
MimeType=application/vnd.adobe.air-application-installer-package+zip
_EOF_

chmod +x /usr/share/applications/NomeProgramma.desktop

Now just look in the “ProgramName” menu and you will start
Probably the additional settings that will create the program will be found in ~ /.appdata/ProgramName

See you soon. Bye

Guide to install and manage tor on ubuntu 4.16 without vidalia

Posted by MD     Category: Informatica







Hi, as I was accustomed to vidalia, I had to endeavor to better manage tor on the new version! But let’s take it easy, first of all we install tor, open the terminal with ctrl + t:
sudo gedit /etc/apt/sources.list
Now it will open a text editor, copy and paste the following line at the bottom:
deb http://deb.torproject.org/torproject.org xenial main
save and close the editor. Always on the terminal to:
gpg –keyserver keys.gnupg.net –recv 886DDD89 gpg –export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | sudo apt-key add – sudo apt-get update

sudo apt-get install deb.torproject.org-keyring

sudo apt-get update

sudo apt-get install tor

then you have to install the proxy:

sudo apt-get install polipo

sudo gedit /etc/polipo/config
insert:

### Basic configuration
### *******************

# Uncomment one of these if you want to allow remote clients to
# connect:

# proxyAddress = "::0"        # both IPv4 and IPv6
# proxyAddress = "0.0.0.0"    # IPv4 only

proxyAddress = "127.0.0.1"
proxyPort = 8118

# If you do that, you'll want to restrict the set of hosts allowed to
# connect:

# allowedClients = "127.0.0.1, 134.157.168.57"
# allowedClients = "127.0.0.1, 134.157.168.0/24"

allowedClients = 127.0.0.1
allowedPorts = 1-65535

# Uncomment this if you want your Polipo to identify itself by
# something else than the host name:

proxyName = "localhost"

# Uncomment this if there's only one user using this instance of Polipo:

cacheIsShared = false

# Uncomment this if you want to use a parent proxy:

# parentProxy = "squid.example.org:3128"

# Uncomment this if you want to use a parent SOCKS proxy:

socksParentProxy = "localhost:9050"
socksProxyType = socks5

Well now you have to configure:
sudo gedit /etc/default/tor

We’re going to put in place of RUN_DAEMON=”yes”

RUN_DAEMON=”no”

Now to prevent the automatic start giving:
sudo systemctl disable tor.service

sudo update-rc.d tor disable

sudo update-rc.d -f tor remove

Now restart your PC! To graphically manage the start-tor instead of vidalia I created a small program with gui Download it here

Put it in your home or wherever you like is important not to move it if you want that it does not require a password:

sudo gedit /etc/sudoers OR sudo visudo

basically enter:
cacccacc
YourName ALL= NOPASSWD: /home/YourName/Tor-polipo.sh

Here now right-click on Tor-polipo.sh in your home, click properties, permissions enable the execution! For firefox you should get “Proxy selector” by Michele Pezza, to manage the proxy now easily go on plugins, manage proxy , add and copy the following configurations:





Good surfing Tor 😉

Firefox 43 add-on plugins enable disabled for invalid signature

Posted by MD     Category: Informatica




Hi, with the latest update of Firefox we noticed that the unsigned add-ins are not activated and there is a button to activate them.
You are stuck with the plug-in written: “plugin name” is not verified for use in firefox. Proceed with caution.
To overcome this problem and continue to use our old add-ons (seprate you trust those not controlled by the Mozilla team), you need to write the address bar:
about: config
then press enter, consent (I promise I will pay attention) now in the search bar write:
xpinstall.signatures.required
now this parameter is defaulti “ true ” you will put one-click “ false
then restart firefox and you will have your add-ons working

Good firefox 😛

Convert directly from a link in firefox PDF

Posted by MD     Category: Informatica





Hi today I’ll show you how covertire a page you are viewing in firefox pdf, unlike the virtual printers will have a true conversion, that we will find a pdf editable, with lots of opportunity to make a copy and paste of texts written in it.
First you need to download my script from here:Download
Then move the file to where it suits you better (no longer have to delete it) and give it execute permissions (right-click> properties> permissions)!
Now go back to firefox and download the plugin that will allow you to call my script if necessary: :
Download version 5.4 (tested on firefox 29) alternativ:
Download latest version from the official site and install it.
Also in firefox go to: Tools> Add-ons> Open With; click Preferences, once open, click on add (bottom right), now a window will open dovre’re going to choose my script “convert-html-to-pdf” that you downloaded before!
Then close the add-ons and if there is no appearance this icon Icona estensione Open With right-click on the top bar of firefox (the one containing the address bar www) and click on customize: move the icon to where we please!
To create the pdf, page (site) you are viewing, just click the icon and click “convert-html-to-pdf” and your desktop trovere pdf 😉
This system is very useful and in addition to being able to copy text from the created PDF file generated weighs very little (based on pages that will save it is still lighter than pages printed from other programs to the virtual press)

Have a nice day and the next guide;)
