Wi-Fi not working on your LiveUSB?

If you need to run a particular LiveUSB on your laptop where the Internet connection through Wi-Fi doesn’t work. I simply find it easier to attach a USB Wi-Fi nano adapter or a dongle. It doesn’t cost very much but be sure to make your Google search first before buying the particular adapter. Choose a stable adapter or dongle that works out of the box. If you make the LiveUSB persistent then you could with the backup dongle install a driver for the internal card if it exists.

I thought this could be valuable information for those taking the MOOC Introduction to Linux.


Photo Podcast

The idea is simple. Combine a number of still images into a html5 slide. Together with the podcast this would create a better experience. One reason to do this is the small bandwidth requirement compared to streaming video. The images doesn’t need to be in sync with the podcast either. Three or four images will answer the basic curiosity. A small bandwidth Audio Codec would be Opus.

Tech Against Stress

Skype has become very easy to use on tablets and smartphones. You can take the conversation with you in every room you like with no hassle. The idea is then that one could use this for some sort of stress counseling. I believe visual communication could have an effect. The suggestion is therefor that there should exist a service for those affected by stress. Calm professionals who can reduce stress.

I hope something like this could be researched.

Enhancement possibilities in a digital curriculum

We can easily convert information to a human understandable form when we speak. Why not take advantage of this when we want to teach math, physics and other subjects. The idea is that in our digitized textbooks we put in links to audio recordings explaining the theory part described in the text form. Because audio recordings are much easier to create than video I imagine cost can be kept down.


Preloaded microSD with Small Business Videos


The idea is to help small business in developing areas with non internet dependable educational videos. Either to improve or to help someone start a business. The videos are to be included on the microSD. The maximum size of the microSD is 32 GB which is more than enough. This way you don’t need an internet connection. Just plug the microSD into the phone or tablet.


Videos could include sewing, haircuts, cooking and more.




Voice Overs for Blogs and Articles

I think you could enhance a lot of sites with voice overs for official articles. Maybe some blogs would also find it interesting. They need not be so complicated. Just someone who reads the article. Clicking on a voice recording would be beneficial especially on mobiles with small screens. With so much to read on the Internet sometimes hearing the text is welcome. It would nice then if adding an audio sample is as simple as adding an image.

A few tips using Audacity.

To remove high pitch noise use the “low pass filter”. Look at “plot spectrum” to see if you got the desired effect. Then apply the “noise reduction” process.


Video Book Reading

I thought it would be a nice idea to have my relatives making video recordings of books. For those with children it could be a fun alternative to the present entertainment. So maybe I could get my grandma to read a couple of children’s books.

These video recordings could be a valuable memory for future generations and perhaps keep an interest in traditional paper book reading.

Refugee Education

As part of an education strategy. I wonder if modern tools such as the preloaded computer tablet can be useful. You don’t need expensive tablets or the Internet for this to work in refugee camps and elsewhere. The idea is that the tablets come preloaded with the whole primary and secondary education curriculum in the refugees own language. Then for those who have missed out on school. With books, videos and exercises they can repeat old material when needed.

Content can be prepared in advance so you have something like the Opon Imo (Tablet of knowledge) for when tablets or other hardware are available.

There are more opportunities than having preloaded tablets. With KA Lite you get an offline version of Khan Academy which I think can be helpful.


To make it more possible I thought I add the idea of Computer Aided Book Exercises.

Looking around I think I have a simple alternative to the usual math exercises found on computers. I don’t think you should waste too much time and resources making them suitable for computer verification. Just provide a link to the answer or solution and let the user compare. Then let the user mark the exercise either successful or failed. If you group together the exercises you can let the user request more of the same or maybe suggest a clarifying exercise. Why you would do this is because it makes it very easy to copy exercises from books. Then with a lot more exercises you can begin to grade them on their knowledge testing and teaching ability.

Improving Email

A while ago I played around with my gmail. The problem I had was that every email from facebook to Linux ended up in the one and only inbox. The solution which has to get a lot easier is to have user rules that automatically puts emails into different folders (labels).

Remembering how many unread emails you have under each label can be difficult. Here you need some additional solution to notify the user of new emails. Since many people have their email with their internet service provider. I hope this kind of solution becomes somewhat of a standard.


Solar Energy Potential For Water Depollution

With the huge progress in solar energy capture there should be a potential for its use in cleaning the environment. Water being essential to life would be a good place to start. I think solar energy could be of use where the location is out of reach from the grid and the otherwise burning of fuel is contra productive. Going from time limited measures to more continuous cleaning would reduce the time and be more effective.

Communities around Open Source Textbooks

I think the next step after the introduction of Internet ready Solar Tablets for developing countries like India and others in Africa is to establish learning communities around Open Source Textbooks. Free books with an open license that makes it possible to keep the book up to date. If successfully implemented these communities could improve the learning experience for the student. Being able download an Open Source Textbook and ask questions on the content of the book, read alternative explanations, view video and cooperate with others on-line would go far.


I think this is where the innovation needs to be, not making the textbook look like something that fell out of a Hollywood movie.
