Use the command ncdu. It is a console program to display disc usage. It has a ncurses GUI. I usually run ncdu -x <some folder>, the x switch is there to not cross filesystem boundaries. apt-get install ncdu ncdu man page

I have set up my pi for use as a web and mail server and it works just fine. So far I have been running from a standard 4GB SD card (with a few modifications described below) and it has had an uptime so far a little over three months. It is not hard and there are many tutorials out there for setting these things up. Incidently I used most of the Ubuntu ...

Yes it is possible; I saw a YouTube video of the Pi reading the news using festival. Use the following command to install festival using Debian $ sudo apt-get install festival festival-freebsoft-utils To make it speak simply pipe it the text or file you want it to read, like so echo "Hello World"| festival --tts References: http://forums.debian.net/...

Raspbian Linux For a long-term OS installation, I would recommend using the Raspbian Linux Distribution, which officially recommended by the Raspberry Pi Foundation. This distribution has the added advantage of having tens of thousands of pre-existing packages, and is based off of Debian, which is one of the most popular (and stable) Linux distributions. ...

You could install espeak: $ sudo apt-get install espeak # For Debian $ sudo pacman -S espeak # For Arch Linux To make it speak: $ espeak "Hello World" # Replace Hello World with your text, must be enclosed by "" $ espeak -f <file> # Read out file <file>

flite is a cut-down version of festival which I have found to work very well on small ARM hosts.

I chose x64 for phone Nope. The pi is not an x86-64 machine. Microsoft has not released a version for the pi yet, but has expressed the intention of doing so. [Later: They have now, follow that same link.] In other words, you will just have to wait. Note there will likely not be a GUI desktop; it will be some sort of headless "embedded" OS.

Arch Linux I'm a relatively new user of Arch, but have been using Linux - mainly Debian and its derivatives - for a few years now. I would highly recommend Arch, for someone who wants to tinker and learn - Debian is too easy... Arch gives you a basic working system, with a package manager. What more do you need? It doesn't even ship with Vim! You can ...

Just mount their shares on the PI - that's your quickest option: pi@raspberrypi /mnt $ sudo mount -t cifs //192.168.0.107/music -o username=sasha,password=somepassword /mnt/music pi@raspberrypi /mnt $ ls -la music/ drwxr-xr-x 0 root root 0 May 20 2007 _ drwxr-xr-x 1 root root 65536 Dec 2 2007 . drwxr-xr-x 3 root root 4096 Feb 12 23:57 .. ...

JIRA will run with a 6-8 second load time on a Raspberry Pi 2 Model B. This is probably too slow for most people and, as such, I was only loading JIRA to see if it could actually be done. Also, the times are on a fresh install. I'm not sure what would happen when you started filling up the database, but I am definitely sure that it would slow to a painful ...

I'd use: du -s * | sort -nr | head -s prevents a lot of unnecessary output, -nr sorts numerically in reverse order and head cuts only the interesting part, you may omit it if you prefer all the results. Also, if you need just an overview of your file system you may use $ df Filesystem 1K-blocks Used Available Use% Mounted on rootfs ...

I would not recommend to do this. Unattended e-mail server very quickly becomes a spam machine, and proper taking care of it very quickly becomes a full-time job. To get a working e-mail server you'll need to acquire a domain name, set up DNS records for your mail exchanger, set up reverse DNS pointers (most internet providers will NOT do that and will NOT ...

feh is a simple image viewer that should do what you want. feh requires X11. You can give it a list of files or directories or URLs. It looks like you might be able to use the --info option to display the IP address. For displaying images on the console (without X11) you can use fbi. It is not a full featured as feh but it will do a simple slideshow. ...

I was going to just add a comment but did not have enough reputation. I use code:blocks (currently version 13.12 in the repository) for C++ development which can be installed via the terminal using: $ sudo apt-get update $ sudo apt-get install codeblocks Then run from the command line with $ codeblocks or from the menu Start > Programming > code::...

We are able to play a version of Minecraft on the Raspberry Pi because the developers of Minecraft ported a version of the game to run on the Pi. After doing some quick research on DayZ using Google; all indications show that DayZ is a Microsoft PC based game at this time. There was some discussion about Bohemian Interactive supporting game consoles (XBox) ...

Since you are using Linux as the remote system, you could use baobab to monitor the file system: If you select Analyzer > Scan remote folder you should be able to remotely build a graphical tree map of the Raspberry Pi's file system, I have tested this using the SSH option and it does seem to work, but also seems a bit slow to generate the tree (I assume it ...

For displaying just static images you can use fbi. You probably want to have some control via your remote ssh session. The method below gives you that. sudo apt-get -y install fbi to install fbi sudo nano /home/pi/slideshow to create an easy slideshow script: #!/bin/bash if [ $1 = "stop" ]; then sudo kill `ps aux | awk '/fbi \-T/ { print $2}'` else ...

You can not monitor voltage, because the Pi has no analog capability. (You could, of course, add an ADC to monitor the voltage.) The under-voltage warning is produced by a chip, and is ON or OFF. SeeRaspberry Pi Power Limitations for details. vcgencmd get_throttled will show the current state. You may be able to write something to monitor this, but AFAIK ...

I've been playing with VLC on a desktop computer the last few weeks. Now, please bear with me a moment... VLC can play natively the FLV and MP4 files that Youtube uses. You just have to know the correct URL. And for the last few years, VLC has had this functionality where you can script it to take the URL of some arbitrary webpage and extract the video ...

First this first: Will your home network support it? You will need a static public IP address and the ability to setup a port forward (port 25) going to your Pi. Your connection will also need to be always up (not dialup, probably not an issue, but worth mentioning.) You will probably have to pay your service provider for the static address. From there, ...

I've been using SVN and WebSVN for more than two years with a (old version 256 MB RAM) Raspberry Pi in my local network, and it worked OK for me - I liked the setup guide Setup a Subversion Server in 4 Minutes. Git on Raspberry Pi is faster with compression turned off. I can recommend gitosis to administer project users, gitweb, and from GitHub, git-...

svn+ssh will likely perform a good deal better than using Apache + mod_svn (i.e. HTTP) as there's simply less that the Raspberry Pi needs to do to handle the requests. You'll probably also find that the whole thing will be more reliable and faster if you keep the repository on a hard disk rather than the SD card. If you do keep it on the SD card then you'll ...

What is the use of Mathematica? Ok, so Mathematica is quite a powerful tool for computational mathematics. The list of its features is too long to be repeated here. While coming from symbolic computation it was developed to include significant functionality in numerical mathematics, statistics, visualization and so on and so on. It's not for no reason ...

Press and hold left alt key, then you can click and drag windows around from anywhere (as opposed to having to click and hold top bar to move windows) Now...

You could use my software info-beamer. Is a software to build all kinds of visualizations. I have example code ready that displays all jpeg files in a directory. Just put the node.lua together with all images into a single directory, then start info-beamer giving that directory as argument. It will automatically pick up new images that are put into the ...

I think the "nano" project - or parts thereof - (that soundly beat me in the Christmas Prizes for Best project of 2015) - might be of interest. It does feature both text-to-speech and speech-to-text if I recall correctly - and Patrick Cook is a currently active member here. Once your reputation gets to 20 (I think) you might catch him in The Bakery (the ...
