      wxMaxima is a graphical user interface for the computer algebra system Maxima:
      a program that solves mathematical problems by manipulating
      equations (and outputting the resulting formula), instead of just
      calculating a number. wxMaxima eases the use of Maxima by making
      most of its commands available through a menu system and by
      providing input dialogs for commands that require more than one
      argument. It also implements its own display engine that outputs
      mathematical symbols directly instead of depicting them with
      ASCII characters.
    
      
      wxMaxima also features 2D and 3D inline plots, simple animations,
      mixing of text and mathematical calculations to create documents,
      exporting of input and output to TeX, document structuring and a
      browser for Maxima's manual including command index and full text
      searching.

Android Virtual Pen allows to send pen input data from your android device to a pc host where it emulates a virtual pen. What distinguishes this solution from others, is emphasis on low-latency to provide the best drawing experience.
      The Android app itself can be found on the github repo at github.com/androidvirtualpen/virtualpen/releases/download/0.1/virtual-pen.apk and soon on the Google Play Store if you wish to support further development.
      Features
      
        Adjustable pen pressure threshold such that you can move the pen-cursor without triggering an unintended click/draw action
        Adjustable pen pressure sensitivity such that you can customize the force needed to be applied
        Eraser support
        Switch between stretched and fixed display mode. In stretched mode, the android device screen is stretched and completely mapped to your PC primary screen. Note that this is required to fully reach the boundaries of your PC screen from your device but causes some slight distortion if the screen ratios (android vs PC) are not the same.
In fixed mode, if the android device screen resolution fits into your PC screen, the android device display is centered and mapped on the host at a 1:1 ratio. This mode should incurr no distortion.
        Detects available usb devices and automatically save your settings for each
        Supports both X11 and Wayland
      
      Usage
      Start the android application connected to your PC through usb. It should warn that the link with the PC is not yet established. For the link to be fully establish, you need to start the virtual-pen app on your PC which will set your device in accessory mode.
    On the linux host, launch the Virtual Pen application, select your device (hit refresh if not shown) then enter the device's screen horizontal and vertical resolutions and then press "connect". 
    Upon the first connection, Android should ask you to allow the Virtual Pen app to handle the connection - press ok.
     Once this done, you should be able to use your pen and see your PC cursor move as intended. Note that this software is still in beta stage and still ought to be tested with various devices.

Advertisement: This package contains only TexLive, a spell checker (Hunspell) and a version control. Via addons you can add support for LilyPond, Sweave and Knitr. After installation you must reconfigure, Tools-&gt;ReconfigureLyX combines the power and flexibility of TeX/LaTeX with the ease of use of a graphical interface. This results in world-class support for creation of mathematical content (via a fully integrated equation editor) and structured documents like academic articles, theses, and books. In addition, staples of scientific authoring such as reference list and index creation come standard. But you can also use LyX to create a letter or a novel or a theatre play or film script. A broad array of ready, well-designed document layouts are built in.LyX is for people who want their writing to look great, right out of the box. No more endless tinkering with formatting details, “finger painting” font attributes or futzing around with page boundaries. You just write. On screen, LyX looks like any word processor; its printed output — or richly cross-referenced PDF, just as readily produced — looks like nothing else.

Denemo is a music notation program that lets you rapidly enter notation. Music can be typed in at the PC-Keyboard, or played in via MIDI controller. The typesetting is done in the background by LilyPond while you work, and is generally flawless publication quality. Any final tweaks to can be done on the final typeset score with the mouse if needed. This represents an enormous practical improvement over the most programs which require you to re-position colliding notation constantly as you enter the music.Unique to Denemo are methods to enter music in a musical, rather than mechanical, manner. You play in a phrase or two of the music using the number keys to indicate the note durations. Audible feedback lets you hear what you have entered; playing the phrase a second time on a real instrument adds the pitches to the rhythm. Again, Denemo gives you audible feedback so that you don’t enter E-flat when you meant D-sharp etc.Another great feature is the ability to put links in the score to the original source document that you transcribed from. Clicking on such a link opens the document for you and highlights the bar you are looking at. You can use this to continue work from where you left off, or for looking back at the source to check a doubtful bar.
