An offline version of Khan Academy.

A free lightweight solution providing high-quality education where you need it most.

Though this software is unofficial, it is known of and approved by the official website.

disliked - because it has no concept of building a larger topic of things to work on, and showing an easy path to progress through them. Needing to pick through a large number of topics, sub-topics and quizzes and then manually and repeatedly going back into that list is inexcusably frustrating.

Installation notes ∞

• I am required to install python, and when I select yes it takes a very long time for it to begin.

  • Perhaps it's downloading it. If so, I want that archive.

It installs:

Python 2.7.10 (default, May 23 2015, 09:40:32) [MSC v.1500 32 bit (Intel)] on win32

.. as of now, the latest versions are:

• 2016-06-25 - 2.7.12

• 2016-06-27 - 3.5.2

It errors with

Could not find pip.exe. Please select the location of pip.exe to continue installation.

Since I installed python to C:\Program Files (x86)\Python27\ I had to select pip.exe from C:\Program Files (x86)\Python27\Scripts\

During install, I got

You are using pip version 7.0.1, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

.. install takes fucking forever, and has no progress indicator.

• I upgraded pip, in case it mattered:

cd  "C:\Program Files (x86)\Python27\Scripts"

pip.exe install --upgrade pip

.. whatever, I'm ignoring this upgrade.

Usage notes ∞

• This is a server/client model. Neat.

• Right-click the tray icon > Options >

  • [_] Run KA Lite when the user logs in.
  • [_] Run KA Lite at system startup.
• When using the desktop icon, nothing happens.. only the tray icon appears.
• Double-clicking the desktop icon create a second tray icon. What god damned amateur night is this?
• I had to read the 0.16.x user manual to find a reference to using http://127.0.0.1:8008/.. but that doesn't go anywhere.
• Exiting and re-starting the tray icon doesn't change this, although I notice the options I selected are not saved.

• Presuming that I broke everything when I fucked with Python, I'll re-do this all from scratch.

Re-installation notes ∞

• I'll manually install python-3.5.2-amd64
• KA Lite requires Python 2.7
• I'll manually install the latest python-2.7.12.amd64 and keep it's default installation directory of C:\Python27\
• KA Lite didn't complain about my manual Python installation.

• When it says it's installing "source files", I presume this doesn't mean the source code to this application.

.. I guess Python's install didn't set the PATH, because during KA Lite's install, I got this:

C:\Python27\Scripts\kalite:129: RuntimeWarning: Could not determine Python in your path, defaulting to c:\python27\python.exe
  warnings.warn("Could not determine Python in your path, defaulting to {0:s}".format(python_executable), RuntimeWarning)

.. oh god this install is outrageously slow.

• http://127.0.0.1:8008/ does nothing, fuck this.
• What the hell.. after some time I get a Windows notification at the bottom-right saying it's running. ARGH
• I have to fucking create an admin account? Oh god dammit, just make this thing go!

• The steps to make this thing go are stupid. I have to register myself? Just go. Just fucking go.

Usage notes ∞

• There's no sound when successful.
• Drag-and-drop requires me to click and drag the icon. It would be nice if it gave me a larger area to click-drag from.
• There are points, but tests don't have a progress or an "end".. they just go on infinitely.
• I had to log out as the admin, then make a user.
• I assumed I'd be logged in as the user, but after doing some more testing with no tracking I noticed I wasn't logged in.
• Logging in as the user, I was able to begin tracked testing, but my first submission gave me some sort of "unable to complete the request" error. Things seem to have worked out since then.
• I can infinitely continue testing, and although my points counter goes green, it keeps giving me more quizes. There's no completion notification and no hint / link to get to the next lessons.
• If I click my username at the top-right, I can click progress, which gives me something like what I'd expect as a progression helper.
• At the bottom of lessons, there is a review feature, but there is no submit button after the comment field. Sigh.
• After learning a whole segment, such as the three parts for "Counting small numbers", there is no easy way to get to the next set of items. I have to go back to the main learning menu. Even then, there's no hint of my progress for any item in any field.
• Wow, apparently mousing over items in the flyout menu will give a wall of text. Bad interface guys. Bad.

• Items which have a radio button and then a number are not lined up correctly. This is annoying as hell.

  • At least I can vaguely click the row and select that radio button.
• Going through a complete segment, I can press back to return to my student report and continue with a segment. This is reasonable, but doesn't help me easily continue on to another major segment or topic.

• The user report should grow from the bottom-up, because it's going to become an astonishingly large list as I progress through many grades worth of items.

  • I don't mind that each item in this list is comically big, but having to scroll through it to find things I'm working on is annoying as fuck.
  • A "shit you're working on" checkbox would be helpful.
• "Make 10 (grids and number bonds)" provides questions which count up incrementally, but should instead have random answers.

• I really like being able to press enter in a text field to answer the question, then press enter again to go to the next question. This means I don't have to reach for the mouse for most questions.
