Tahrpup 6.0 CE in my old Acer Aspire 5315

I have recently installed Tahrpup 6.0 CE in my old Acer Aspire 5315. It has some heating issues. It used to power off after 20 mins in my first login. After subsequent reboot, it is stable, even it gets overheating also. I recommend this Puppy Linux for old desktops, which has very small in configuration. It is built with Ubuntu 14.04 packages compatibility.
I wrote this post in the same os with the newly installed Google Chrome32. :)

1. Light weight and easy to use.

1. Laptop overheating problem, especially for Acer Aspire 5315 model.

Ubuntu 15.10 Features

Major 5 features:
1. New Overlay Scrollbars
2. Overlay Scrollbars in Ubuntu 15.10
3. Overlay Scrollbars in Ubuntu 15.10
4. Ubuntu 15.10 features new scrollbars.

Canonical has dropped its own Unity Overlay Scrollbars, which were thin, hidden, and had hard-to-hit pop-out handles, and replaced them with upstream GNOME’s take.

GNOME overlay scrollbars are auto-expand when mouse over so as to save space in applications and have a large ‘grab’ area to make them easier to move.

Unity 7.3.3
‘Unity has received some small fixes and usability improvements’
Unity, the default desktop shell, has been handed a batch of small fixes and usability improvements for Ubuntu 15.10.

For example, you can now drag and drop apps from the Unity Dash to the desktop to create shortcuts, and navigate through Dash results using keyboard navigation keys.

The Unity Dash search box text and BFB tooltip no longer make mention of ‘online sources’ when you have online source searching set to ‘disabled’ under System Settings > Privacy.

Other changes in Unity 7.3.3:

You can now drag and drop apps from the Dash to the desktop to create shortcuts
Page up/down keyboard navigation works as scroll in the Dash
Dash title & BFB tooltip is updated based on your privacy settings
Session exit buttons now have a click effect
Fix to prevent ‘shutdown’ of computer when screen is locked
Active app icons now show unfolded when launcher accordion triggered
Fix for full screen menubar
Fixes issues with ‘show desktop’ that caused window decoration for two windows of same app to vanish
Dash: Non-expandable category headers skipped in keyboard navigation
Dash: Non-expandable category headers are no longer highlighted on mouse over
Dash: screenreader and KeyNav fixes
New setting to control the show-now delay (when pressing Alt key)
Logic tweak to stop adjacent menu opening when moving from an indicator icon to its menu

Linux Kernel 4.2

The Ubuntu 15.10 kernel version is 4.2, released at the end of August.

This brings better hardware support, including initial support for Intel’s 64-bit “Broxton” Atom chips. There’s also new AMD GPU driver supporting recent Radeon GPUs, and F2FS file-system encryption support.

Ubuntu Make
Ubuntu Make, a command-line utility that makes installing popular developer tools easier on Ubuntu, now supports even more platforms, frameworks and services, including a full Android development environment.

Persistent Network Interface Names
Ubuntu 15.10 introduces stateless persistent network interface names — a technical feature that, for most of us, has little bearing on how Ubuntu runs.

In short it allows interface names for networking hardware to be maintained between reboots, kernel updates, driver changes or hardware being unplugged or removed.

Updated Apps
Application updates (naturally) feature.

Firefox 41
Chromium 45
LibreOffice 5.0.2
Nautilus (aka ‘Files’) 3.14.2
Totem (aka ‘Videos’) 3.16
Rhythmbox 3.2.1
GNOME Terminal 3.16
Eye of GNOME 3.16
Empathy 3.12.10
Shotwell 0.22

What is DNF?


DNF stands for Dandified yum. Since DNF is a tech preview in Fedora 18 the Python module names can not be 'yum.*' as that would clash with yum itself.
Why not zif/zypp?

People are asking why we didn't choose to adopt zif (or SUSE's zypp) instead of fixing yum. The reasons are:

    dnf looks for a middle ground between a sane API and some backwards compatibility.
    dnf and hawkey are first steps toward using the same resolver across the entire stack.
    Libsolv is a well tested and proven code base, currently the most sophisticated and optimized dependency solving implementation.

Benefit to Fedora

Hawkey clients will get:

    easier bindings to other languages than Python
    concise, clear package management API
    better performance (through utilizing libsolv)

The set of possible hawkey API consumers:

    dnf (the next generation yum)
    release engineering tools
    graphical package management tools

DNF clients and users will get:

    Faster and simpler package manager.
    Simplified client code.
