Valentina – Open Source Pattern Making Software for Clothing

Last updated: March 26, 2015

Valentina is an open source pattern making program for clothing. It allows pattern creation using either standard sizing tables or an individual’s set of measurements. It blends new technologies with traditional methods to create a unique pattern making tool.

Currently, there is a lack of affordable software tools designed for creating patterns. Some people faced with this problem resort to using CAD tools or graphical editors designed for other purposes. However, these tools are inadequate when performing certain pattern making tasks (e.g. adding seam allowance, truing a dart, walking a seam). Moreover, these programs are good enough to create a pattern in a single size, but when you want to make changes for another person, you can’t do it quickly. You need to create the pattern from scratch. This is where traditional methods of pattern drafting can be very useful. Why can’t you tell a program how to change the pattern so you don’t need to do it ever again?

How to install Valentina in Ubuntu:

Open terminal from the Dash/Menu or by pressing Ctrl+Alt+T on keyboard. When it opens, run commands below one by one to install the software from PPA:

sudo add-apt-repository ppa:dismine/valentina

sudo apt-get update

sudo apt-get install valentina

Or you can download the .deb binary from PPA packages page and install it via Ubuntu Software Center.

Ubuntu 14.10, Ubuntu 14.04, Linux Mint 17 are supported so far!

Install 3D CAD Model Creator ‘OpenSCAD’ 2015 in Ubuntu 14.04

Last updated: March 22, 2015

OpenSCAD is a software for creating solid 3D CAD objects. It focuses on CAD aspects rather than artistic ones.

OpenSCAD is not an interactive modeller. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script. This gives the designer full control over the modelling process and enables him to easily change any step in the modelling process or make designes that are defined by configurable parameters.

While Ubuntu repositories provide a very old version, the most recent OpenSCAD 2015.03 was released with a number of new features, improvements and fixes:

Language Features

Added text() module for 2D text
Added offset() module for 2D offsets
Added list comprehensions and let()
Added concat() function
Added chr() function
surface() can now take PNG images as input
min() and max() can now take a vector argument
2D minkowski can now handle polygons with holes
Variables can now be assigned in local blocks without using assign()

Program Features

Added Toolbar icons
New code editor based on QScintilla
Added Splash screen
Added SVG export
Added AMF export
Added --viewall and --autocenter cmd-line parameters
GUI is now translated into German, Czech, Spanish, French and Russian
MDI (Multiple Document Interface) is now available on all platforms
Color schemes for viewer and editor can be user-edited using JSON files
GUI components are now dockable
Added Tickmarks on axes

Bugfixes/improvements

Performance improvement: 2D (clipper), preview, hull, minkowski, surface
Performance improvement: Reduce duplicate evaluation of identical expressions
Better recursion behavior
STL export and import is now more robust
Internal cavities are better supported
New examples
Windows cmd-line behaves better
Better mirror() and scale() behavior when using negative factors

Deprecations

polyhedron() now takes a faces= argument rather than triangles=
assign() is no longer needed. Local variables can be created in any scope

Twitter Client ‘Corebird’ 1.0 Released [PPA for Ubuntu 15.04]

Last updated: March 21, 2015

Open-source GTK3 twitter client ‘Corebird’ 1.0 was released recently with lots of improvements. users of Ubuntu 15.04 can now install it from PPA.

Corebird is a native GTK+ Twitter client for Linux which has a modern and responsive design that looks kinda similar to the official Twitter app for Mac.

It’s one of the few remaining Twitter apps still in active development for Linux. With the advantage of the latest GTK+3 features, the application makes use of the new Header Bars. With the gstreamer and gstreamer plugins, corebird allows to view any videos, animated GIFs (added in 1.0 release).

Changes in Corebird 1.0:

All dialogs now use client-side decorations if the environment dictates it, otherwise they fall back to server-side decorations (compose dialog is excluded).
Many layout updates
The compose window now allows for up to 4 pictures to be uploaded.
now save additional information about the account which makes it possible for blocked users to be actually blocked, i.e. streamed tweets won’t appear in your timeline anymore.
When (un)following someone, now also correctly show/hide their retweets in the stream.
The DM page now sorts threads with unread messages first.
The @handle completion known from the compose window is now also available when composing Direct Messages, as well as in the account settings for the description.
Everything app-specific should now be hidpi ready, the only thing missing are assets loaded from Twitter directly, i.e. avatars and media.
Notifications should now get withdrawn whenever it makes sense, i.e. if you read a Direct Message before dismissing the notification, it should get withdrawn automatically.
The hover buttons moved to a right-click menu on every tweet.
Plurals are properly localized.
We now also respect muted users (even though there’s no UI to mute someone)
A user’s verification status is now also shown in the tweet info page.
Everything should now work when the user’s @handle (aka screen_name) changes.
Switching to the same page (i.e. going to a profile from the profile page) now works much better, including the swipe transition as well as proper equality checking.
Invalid inline media (file size too big, 404, …) should now be properly detected and reacted upon (i.e. remove the widget in the stream, add the link back).
Underlines in @handles are now properly displayed in the app menu (i.e. the “open account” submenu)
Animated gifs from Twitter are now also handled (just like other videos).
Tweets in timelines are now single-click activated. This unifies the behavior with all other lists in the application. Since this interferes with certain user behaviors, there’s a setting to switch back to double-click activation.
Based on a user’s protection status, we now disable (or hide) retweet buttons of tweets.

Install Corebird 1.0 in Ubuntu:

Due to the updated dependencies (GTK >= 3.14), Corebird 1.0 only available in PPA for Ubuntu 15.04 Vivid.

Open terminal (Ctrl+Alt+T) and run below commands one by one to add PPA and install Corebird:

sudo add-apt-repository ppa:ubuntuhandbook1/corebird

sudo apt-get update

sudo apt-get install corebird

Above commands will also install an old version (Corebird 0.9) for Ubuntu 14.10 Utopic.

How to Restore The Default Login Screen in Ubuntu 14.04

Last updated: March 17, 2015

After installing another desktop environment (e.g. KDE, MATE, Cinnamon) in Ubuntu Unity, the default login screen may be replaced after restart.

Here’s the quick tip for those who want to restore the default login screen, Unity Greeter, in Ubuntu 14.04 and/or Ubuntu 14.10, so it looks like:

1. By default, Ubuntu Unity uses Lightdm display manager to handle its login screen. But installing Gnome Shell or Cinnamon Desktop also installs the GDM or MDM display manager.

So you may first run below command in terminal (Ctrl+Alt+T) to make sure LightDM is in use by choosing it from the prompt:

sudo dpkg-reconfigure lightdm

2. LightDM also supports “themes”, some DEs use LightDM-GTK-greeter instead of the default Unity-Greeter as its theme.

The easiest way to restore LightDM theme is:

Open terminal from the Dash or by pressing Ctrl+Alt+T on keyboard. When it opens, run command to edit (or create) /etc/lightdm/lightdm.conf:

gksudo gedit /etc/lightdm/lightdm.conf

If need, install gksu from Ubuntu Software Center

When the file opens, change its content to (or paste below content):

[SeatDefaults]
greeter-session=unity-greeter

Save the file and you’ll see the default login screen at next boot.
