Fedora 24 alpha - VirtualBox and FreeCAD software.

Today I tested the FreeCAD under Fedora 24 alpha with VirtualBox.
First I update my system using the standard updater for your desktop:

sudo dnf update --refresh
sudo dnf install dnf-plugin-system-upgrade
dnf install freecad freecad-data

About this software the official webpage told us: FreeCAD is a parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. FreeCAD is open-source and highly customizable, scriptable and extensible.

Is working well and you can read more from here.
I have some problems with sound under my VirtualBox.

I think something block the memory when I try to make some screenshot.
See this video:

LibreOffice Viewer - tested.

I like LibreOffice because is opensource with a great team development.
Can be used with Windows and Linux.
Today I will told about the Android OS and LibreOffice.
LibreOffice is now available on Android as a native application with this formats:
• Open Document Format (odt, ods and odp);
• Microsoft Office 2007/2010/2013 (docx, xlsx and pptx);
• Microsoft Office 97/2000/XP/2003 (doc, xls and ppt).
Named LibreOffice Viewer comes with a first preview of the editing functionality and is sized to APK:48 MB / App installed:81 MB.
I think is need to improve this application with viewer for epub and some ebook document formats.
This will remove some applications.
Note: Microsoft Office come with 1GB of RAM and also can be used.

News: The new Google Spaces from google.

Google Space it's a way for groups to quickly share text, images, videos or links.
This news was announced yesterday by Google and is available as a web service and in form of native applications for Android and iOS.
If you want to access Spaces then this is not protected.
The only security that prevents uninvited users from accessing a Space is a random invite string.
The customization options let you change the header graphic, change colors, and add a name to space, but that is about it.
Google Spaces is part Google Plus and part Wave and will come with new features.

Fedora 24 alpha - Twine software.

About the Twine - you can read from official website:

News: About Fedora 24 Alpha.

I used Fedora 24 Alpha because is a great operating system.
First I will share some links with more info about Fedora 24 Alpha.

If you want to read about the release schedule for Fedora 24, then take a look at Fedora 24 - Releases Schedule.
What is Alpha a release?
A release contains all the features of Fedora editions in a form that anyone can help test.
Where you can get it?
You can read and download this release from here.
...now about testing the new Fedora 24.
You can make one Live DVD /CD or just use one virtual machine software like Virtual Box.
The Virtual Box software from Oracle it is an x86 virtualization software not just for Linux distro but also for any operating system. You find many tutorials about how to do that.

So, I install the new Fedora 24 Alpha and I test it. 
First, the team makes a great job with this features:
- not many packages ;
- the speed of my VirtualBox is good with virtual Hyper-V, enabled 3D - Acceleration and 64 Mb on video was under 1 min to see the first screen and almost 2 min to start the GUI install on a hard disk with my old Intel(R) Pentium(R) CPU 2117U has 1.80GHz;
- the design starts with a beautiful wallpaper; 
- the installation GUI is simple;
- the size on disk to make the first update I used is 15Gb - is too much for me;
- the initial size of the installation comes with ~6Gb;
- the last Virtual Box version 5.0.18 r106667 come with full network settings so you can use the internet to update Fedora packages and use the browser.
I don't use this distro with Live DVD or install on my HDD but you can do that...
I want to make this article more complex but is enough for now ...

Regards. 

 

Tested the Libre Office software.

Today I tested Libre Office suite. The last version is 5.1.2.2 and has many features.
I like to used because I can export my work under Microsoft Office and also to open document.
You can download it from libreoffice official page.
This software can be used with many ope systems, like:

• Linux x64 (deb)
• Linux x64 (rpm)
• Linux x86 (deb)
• Linux x86 (rpm)
• Mac OS X x86_64 (10.8 or newer required)
• Windows
• Windows x86_64 (Vista or newer required) 

You have LibreOffice come with Impress, Calc , Writer, Math and Draw to deal with any type of issue.  I don't like for example the way to rename the macro. You need to go to : Tools -Macros -Organize Macros -LibreOffice Basic.. the Organizer button and finally double click to the name of the macros , rename and close. I think this come from permisions of the macros.
Also You can deal with macros what do you want. For example in this example I delete some fields from one document - one matrix make from A3 to B10.

  Dim myDoc As Object
  Dim mySheet As Object
  Dim myCell As Object
  Dim myRange As Object
  Dim myFlags As Long
 
  myDoc = ThisComponent
  mySheet = myDoc.Sheets(0) ' Refers to Sheet1 as in 0, 1, 2 etc
  myRange = mySheet.getCellRangeByName("A3:B10")
 
  myFlags = com.sun.star.sheet.CellFlags.VALUE + _
      com.sun.star.sheet.CellFlags.DATETIME + _
      com.sun.star.sheet.CellFlags.STRING + _
      com.sun.star.sheet.CellFlags.ANNOTATION + _
      com.sun.star.sheet.CellFlags.FORMULA + _
      com.sun.star.sheet.CellFlags.HARDATTR + _
      com.sun.star.sheet.CellFlags.STYLES + _
      com.sun.star.sheet.CellFlags.OBJECTS + _
      com.sun.star.sheet.CellFlags.EDITATTR
 
  myRange.clearContents(myFlags)

This is a simple type of macro using LibreOffice Basic language. You can also use Python , BeanShell, JavaScript.
So if you like this software and you want to survive this software, you can make a donation of at least 5 USD.

LibreOffice is Free Software and is made available free of charge. Your donation, which is purely optional, supports our worldwide community.If you like the software, please consider a donation.
