Interview with Jolla [questions and answers][updated!]

I would like to do a short online interview with Jolla about how the workspace of sailors looks like. I’ll post some questions here and if Jolla wants they can answer the questions in the comments area ;) I’m sure the other fans would like something interesting to read about Jolla while they wait for the first device to launch

[UPDATE]:Jolla has replied to the questions. So you can now read the answers :)

[Question 1]: What OS do sailors (mostly) use during working hours?
[Answer 1]: GNU/Linux (I didn’t expect anything else :D ;) )

[Question 2]: If the answer to question 1 is “GNU/Linux”, what desktop environment/window manager do (most) sailors (mostly) use during working hours at Jolla?
[Answer 2]: Basically the 3 biggest Linux DE’s are about equally used within Jolla and some other DE’s/WMs are also used, but less. It looks like the market share of DE’s/WMs within Jolla pretty much reflects that of the whole Desktop Linux landscape.

[Question 3]: If the answer to question 1 is “GNU/Linux”, what distribution/distro do (most) sailors (mostly) use during working hours?
[Answer 3]: Ubuntu wins, but there are lots of Fedora users within Jolla too. And also other distros. It surprises me that Ubuntu (which is Debian (.deb) and apt-get based) wins, where as Mer and Meego (where Sailfish is based on)is RPM based and uses zypper. I’d expect to see openSUSE usage (which is both RPM-based and uses zypper, just like Mer does). But at least it shows that the Jolla guys are quite flexible and can work with both tools.

[Question 4]: What are the favourite editors/IDE’s from (most) sailors? Qt Creator? KDevelop? vim? emacs? kate?
[Answer 4]: Both Qt Creator and vim/emacs commandline editors heavily used within Jolla. This isn’t too surprising.

[Question 5]: Which programming language do (most) sailors prefer during working hours when programming QML apps for Sailfish, JavaScript of C++?
[Answer 5]: Well basically a bit of everything seems to be used inside Jolla. With C++ and QML/JavaScript clearly leading the pack.

[Question 6]: Which language is primarily spoken inside Jolla during working hours? English? Finnish?
[Answer 6]: English is the language that primarily is spoken within Jolla, which makes sense because Jolla seems to employ people from lots of different countries. Jolla was founded by Finnish people and a lot of Jolla employees are Finnish. Therefore it also makes sense that Finnish is spoken too.

Opera Mobile (possibly using WebKit) spotted on Sailfish OS!

Today while watching one of the recent Jolla Sailfish UI demo/interview YouTube video’s with Marc Dillon, when he scrolled the appscreen, I spotted Opera Mobile with a blue icon between the apps! This is very interesting because it means that Opera Mobile is already ported to Sailfish OS, on the Slush event (last year 21/22 November) Jolla had already revealed that Opera Software was one of their partners.

So far Jolla didn’t show the default web browser app of the Sailfish OS, but because Opera is a Jolla Partner (or friend as they prefer to call it) and Opera Mobile is already running on Sailfish, it wouldn’t be suprising if Opera Mobile will be the default browser on Sailfish OS.

But that’s not quite the big thing: what’s even more interesting is the combination of the blue Opera Mobile icon (Opera always uses a lot of read and their app icons are always red) and Opera’s recent switch to the WebKit rendering engine.

Recently the web was quite shocked by Opera’s announcement that it was switching to WebKit and ditching it’s homegrown Presto rendering engine, which Opera has been using ever since it released it’s first web browser product. Many people asked theirselves why Opera decided to switch to WebKit. But what I had already suspected when I read the news, seems to be true: Jolla seems to have asked Opera to ditch it’s closed source Presto for the open source WebKit engine! But why would Jolla want to let Opera use WebKit instead of Presto for it’s default mobile Sailfish OS browser? Well maybe Jolla really wants it’s Sailfish OS browser to be open source!

Want the evidence? Well here it is ;):

Still not convinced, well here’s the link of the YouTube video:

Pause the video at 1:54 and you’ll see when I toke the screenshot
Also notice the blue color of the icon: the WebKit logo is also largely blue.

Version 1.0 of Pythagorean Python released!: complete rewrite, more functionality

Hello everybody I’m proud to release version 1.0 of my little Python 3 script: Pythagorean Python. Version 1.0 is a complete rewrite of version 0.4 and more functionality is added. Here’s the change log:

-Rewritten (pythonic and correct design)
-Functionality to track score added (if “myscore” is given as “answer” the program will print your current score)
-Functionality to check if the OS is compatible with the script (Pythagorean Python currently only runs on Linux)

-Layout of output was changed for the sake of better readability.

-If “exit” is given as “answer” the program quits

Why this version wasn’t named version 0.5? Well it is rewritten to be pythonic and correct and tested again. I think it contains the necessary parts to be mature enough to get labeled 1.0

Planned for version 1.1 is functionality to save a high score. Planned for version 2.0 is GUI. Planned for version. Planned for version 2.1 is a built-in calculator. Planned for version 2.5 is a drawing area where the triangle is visually represented.

Learning Python 3

Hi everyone,

I recently started learning Python 3 (as my first programming language) and I’m now reading the book: “Beginning Python Using Python 2.6 and Python 3.1″(ISBN: 978-0-470-41463-7). I must say it’s really good book so far. It teaches you the absolute basics and once it’s done with that it starts teaching you interesting things like letting Python 3 create and communicate with databases (for example MySQL and Sqlite), reading, editing, etc. XML files, working with files and directories, text processing, network programming (TCP/IP and also IMAP, SMTP etc.), writing basic GUI programs with Tkinter and even more things. I would really recommend it.

 

I myself am currently at the part of learning the basics of OOP (Classes and Objects) and as exercise I’ve written my own class. I’ve tried (and am still trying, as the class is not done yet) to use as much of Python’s functions and keywords as possible to teach myself Python. In the class I used the “try: except:” statement for the first time. Also used the “pass” keyword for the first time and used the “os.system()” function to start firefox with as parameter a weburl. I also used the “for in”-loop for the first time and used the replace function to replace spaces with “%20″ in an Google Search url.

 

My class is called car and it’s objects/instances store information about the car and can perform a web search with the known information. The class has the following methods:

  • load_basic_info(info_type, info_value) – With this value you can load basic information about the car in a built-in dictionary. Like brand name, model name, color, model year, version etc.
    for example calling it could look like this:
     subimpreza.load_basic_info(“Brand”, “Subaru”) The first parameter specifies the name of the to be created key or the existing key of the value. The second parameter specifes the value in the dictionary.
  • list_basic_info() – lists the available info about the car. For example if I would have specified the brand name, model name, color and model year with the “load_basic_info”-method, the output could look like this:

        Blue

        Toyota

        Corolla

        2006

        Minus the white lines between the values (couldn’t get the formatting right in WordPress ;) )

  • search_info_on_web() – Tries to combine the brand name and model name values in the built-in dictionary and launches Firefox and searches Google with the “<brand name> <model name>
  • If there isn’t a brand name value and/or model name value in the dict a KeyError raises automatically by Python and that KeyError will be caught by a “try: except:”-clause which will print a message on the screen with the message that there is not enough information available to perform a web search and it asks the user to load more information with the “load_basic_info()”-method.

The source code of my class can be download below. I recommend to start the script with “python3 -i” so you can mess around with the class and it’s methods in interactive mode after Python has loaded and read the script. The code is available in public domain and maybe used by anyone, everywhere for any purpose. If you reuse the code I will be happy if you were so kind to credit me for the code and include a link to my blog.
