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.

Once installed it’s seen at 127.0.0.1:8008

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

error

.. 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 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.

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.
