There are several methods you could use to generate a file filed with random data under Linux. In the example below dd has been used to generate 1,000,000 bytes of random data.
dd if=/dev/urandom of=./randI.hex bs=1MB count=1
If you want a file filed with zeros you could substitute /dev/urandom with /dev/zero.
To get details and the value of emacs variables such as the load-path variable enter the following:
‘C-h v load-path RET’where C-h represents pressing the <ctrl> key followed by the character ‘h’.
MiniDLNA is a piece of server software implementing the DLNA/UPnP protocols. The software serves media files (music, pictures and video) to clients on a network. THe software discussed here has been used along a number of Roberts Istream Radios, as well as the VLC app running on android phones, Ipad tablets and PC
There are several sources for the code on the internet. Alternatively you could use the sources given below. These have been modified to include support for composer and author tags. The code as compiled here has been in use for many months. We can however take no responsibility for any problems you may have as a result of it.
To begin with you may need to install some additional packages as shown below. So long as these dependencies are met the following should be sufficient for building the sources on fedora30, ubuntu 18.04 and the Raspberry Pi. I used the following sequence on ubuntu and the Pi, and the one below that on fedora30.
Ubuntu/Raspberry Pi
$ sudo apt-get install autoconf $ sudo apt-get install autopoint $ sudo apt-get install libavutil-dev $ sudo apt-get install libavcodec-dev $ sudo apt-get install libavformat-dev $ sudo apt-get install libjpeg-dev $ sudo apt-get install libsqlite3-dev $ sudo apt-get install libexif-dev $ sudo apt-get install libid3tag0-dev $ sudo apt-get install libogg-dev $ sudo apt-get install libvorbis-dev $ sudo apt-get install libflac-dev $ sudo apt-get install gettext
Fedora30
$ sudo dnf install autoconf $ sudo dnf install automake $ sudo dnf install gettext-devel $ sudo dnf install \ https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm \ https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm $ sudo dnf install ffmpeg-devel $ sudo dnf install libjpeg-devel $ sudo dnf install sqlite-devel $ sudo dnf install libexif-devel $ sudo dnf install libid3tag-devel $ sudo dnf install libogg-devel $ sudo dnf install libvorbis-devel $ sudo dnf install flac-devel $ sudo dnf install make
Extract the sources using tar and switch to the directory. You should now be in a position to compile the code using the following sequence of commands.
$ tar -xjf minidlna.tar.bz2 $ cd minidlna $ ./autogen.sh $ ./configure $ make
To install and then check the installation you can enter the following commands
$ sudo make install
$ sudo checkinstall
Once you have built the application you will need to point MiniDLNA at your files by altering the contents of the minidlna.conf file, and the fire the whole thing up with a command similar to the one given below
sudo /usr/local/sbin/minidlnad -R -f ~/.minidlna/minidlna.con
To get the full benefit of the code you may need to set the tags associated with your mp3 files. The following screenshot shows how an audiobook has been configured for use here.
For instructions on how to start minidlna automatically when the system is powered have a look at Minidlna: How to Auto Start.
At the time of writing the default ubuntu installation of Umbrello was version 2.24.3, whilst umbrello built from downloaded sources was 2.31.70.
You can download the umbrello sources from github using the following command
$ git clone https://github.com/KDE/umbrello.git
In order to build on my ubuntu 18.04 setup I first had to install the following packages.
$ sudo apt-get install cmake $ sudo apt-get install -y extra-cmake-modules $ sudo apt install libqt5svg5-dev $ sudo apt-get install libqt5webkit5-dev $ sudo apt install kinit-dev libkf5crash-dev libkf5notifications-dev libkf5notifyconfig-dev libkf5parts-dev libkf5kcmutils-dev libkf5newstuff-dev libkf5coreaddons-dev libkf5i18n-dev libkf5dbusaddons-dev libkf5config-dev -y $ sudo apt install libkf5activities-dev libphonon4qt5-dev -y $ sudo apt install libkf5baloowidgets-dev libkf5filemetadata-dev libkf5kdelibs4support-dev -y $ sudo apt install baloo-kf5-dev -y $ sudo apt install libkf5texteditor-dev -y $ sudo apt install libxml2-dev $ sudo apt install libxslt-dev
You should now be able to build the application using the following command sequence
$ mkdir umbrello/build $ cd umbrello/build $ cmake -DCMAKE_INSTALL_PREFIX=$HOME/umbrello -DBUILD_KF5=1 -DCMAKE_BUILD_TYPE=Debug ../ $ make
and then run with the command
$ umbrello/umbrello5 &
