With millions of refugees needing education. Maybe we should think about multiple ways to improve it. What if we had a primary and secondary curriculum preloaded on a tablet that is adapted for teaching. Here a grown-up non teacher could teach a single class with the tablet as a teaching aid after some training. I don’t know what the content would be but surely it should contain lesson plans for each day, videos, exercises all adapted for a teacher.
I think the content could be useful for parents also as a way to help their children.
My idea is pretty simple. Just by changing the name of an existing battery from a direct current battery to an alternating battery. I wondered, what would an alternating battery mean?
Now an alternating current battery might not make much sense. However after seeing the below image showing the current density in a particular battery. I thought why not make the current density more even over time across the surface.
Maybe one solution would be to use one or more extra pairs of plus and minus which you then let an electronic switch alternate between. Those pairs are connected at smart locations around the battery so you get a more even distribution over time. However only a single pair is active at one time.
Another example battery showing an active pair in red and a pair in black. The second pair is activated after the first.
The idea is that an electronic switch alternates between the different pairs. Creating a more even current density in the battery over time during discharge and possibly charging. The optimal time between active pairs is something I don’t know though.

I was thinking. There should be an online cooking course that teaches you how to make good nutritious foods or dishes that are environmentally sustainable. Since its such an import subject there should be much information. I believe the course should be self paced, have videos and assignments. For fun photos of the foods from the learners could be shared. I believe maybe such a MOOC could make a difference. For the environment and maybe for all of those who need to loose weight.
I think there should be more information on climate change adapted dishes. My guess is that they contain less amounts of meat than we are used to. What I figured out is that our plate model is not really good for this. If you divide the food into groups you are likely to get equal amounts of each. What I’m suggesting is that the meat should be distributed on the other groups so that if we need to eat less meat it will still look good.

The idea is simple. The reason I don’t want paper advertising is that it generates a lot to be thrown away. From this I got the idea that for electronic advertising email maybe the delete part could be made into a feature. The idea is then that serious companies could make life easier for people by adding a code to their emails that tells the mail server when to delete or hide their message. For instance how long the mail should reside on the server if it has not been viewed. Here the reason could be that the mail is advertising some low prices that is only valid for a week or so.
I wonder if this could work. Perform some statistics on a lot of existing code divided into several types of categories. Be it games or utilities. Python or any other code for that matter. By scoring how frequent a module and it’s submodules are you get an overview of what is important for that type of program. Then if you as a learner want to make a program in such a category you can then start to read about the most used modules and submodules first.
Example statistics of submodules in pygame from 15 simple python games.
The idea is simple. Using ssh you can login and run commands on your wifi connected Raspberry Pi. In the image below I use a simple USB soundcard that I have connected to my amplifier. From the terminal you then play music with mplayer and change some of the volume with alsamixer. Choosing Raspbian from NOOBS works just fine.
To get the usb soundcard selected at boot then edit /etc/modprobe.d/alsa-base.conf with
I had the idea to replace my desktop computer with the hardware similar to that found in a mobile phone for a long time now. I think this is important because the Internet is a part of every day life and you should be able to buy cheap computers. What I can say is that I really like this little quad core computer. Youtube will work depending on the browser. In Epiphany I got a working html5 player. The best part is that it worked wonders with my little external USB Xonar U3 sound card. With mplayer * and ALSA the sound in the headphones sounded very good. I would not take a chance in buying an expensive sound card for the raspberry pi 2 at this time but if you have one extra it will be worth testing.
I previously surfaced the idea of an International Employment Service For Refugees at my blog at peroglyfer.se. Then I thought since we have MOOC’s and other forms of online education for Linux maybe we can have a Linux Employment Service also. To cover more job opportunities. Could the Linux community come up with software solutions that would better match employers to employees?
With cheap 8TB drives it should be possible to provide simple wifi web servers in rural schools with a good portion of the internet. Even if you send them per boat it will be way faster than some satellite solutions. If the shipment takes one month thats 267GB/day. With such massive storage also schools with unreliable internet connection could provide a better experience for their students.
Youtube is a place where a lot of content is stored. I’m thinking content owners who wish their videos to be shared easily can attach a creative commons license to their videos so that they can be copied.
Another excellent portion of the web are all the courses that exists. MOOC’s and such. What if some of these courses with their videos and grading software could be stored on these harddrives. Here we have an opportunity to give access to higher education for those with an unreliable internet connection or non at all.
The idea is regardless of your financial situation there should exist a place similar to that of a tech hub. A physical meeting ground where people can cooperate, learn and generate ideas and startups. I think adding this functionality to libraries makes sense today because books and other written text are now Internet based or electronic. They do not take up important space. Making this place for the public is important because everyone have something to contribute.
I came up with this idea when thinking about ordinary painting. Here you make alterations and adapt so that the whole of the painting looks good. From this I can imagine there will be times when you don’t know exactly in advance how a blueprint for a product will look like at the time of manufacturing. Like the way you need training to paint maybe you could train a computer program to make smart alterations to the blueprints under the manufacturing process. I speculate that if a small error is made under a 3D printing process the software will decide on an adaptation. With this I believe waste will be less and perfection will be easier to achieve.
Reading is as important in this century as in the previous one. Since reading will begin to take place on tablets I suggest the following idea.
The idea is to make tablets or smartphones easy and comfortable to read on. Since LEDs are small why not have two types. One ordinary backlight for perfect colors and one additional ”warm” backlight adapted for reading. With warm backlight I mean backlight similar to warm LED bulbs. Then using an optional switch in android for the tablet people wont strain their eyes trying to read a school textbook.
Inkscape is a vector illustration software that you can download for Linux, Mac or Windows. I thought why not use this for making small changes to documents that have been exported to the PDF format. Since you edit one page at a time a software to join the pdf files is then used. I used pdftk for this.
In the example below I will change some text and a photo.
Here is an idea that would give the possibility of variations from the same clipart. With cliparts existing as a 3D models you can rotate. Change camera angle for the scene. Maybe change material, color or textures. This way you get a unique clipart image to be used in your text every time. The simple way to implement this is to use Blender (3D program) to render the cliparts you like from a site where people upload their free 3D versions of the typical clipart images. The 3D versions should be finished scenes in Blender so that they could easily be rendered.
The idea is simple. With many time consuming games on PC, Playstation or Xbox. Having control over the time your child is playing can be important. Since today many games require an Internet connection. One could therefor have two online accounts at the game site. One special account for parents who could then see how much time the child is playing a particular game. Here you could set at what time the game is allowed to be played simply by logging into your account from your own computer.
I might have an idea for refugee employment. If this is suppose to scale maybe there is a need for an ‘International Employment Service For Refugees’. Where companies, organizations and ordinary people could post distance or regular work for refugees across the globe. With the Internet this should not be totally impossible.
I thought I focus this blog post on the possibility of creating Internet jobs. The idea I had in mind was to add entertainment to sites selling electronics, clothes and other items. It’s pretty simple. If the idea is good companies will then hire people to do interesting blogs and podcasts. I think a photo podcasts will be more interesting since you can advertise with photos or short videos of products. A photo podcast can be done the easy way by adding the audio track to a video of still photos. I believe this idea could generate some new jobs and at same time help to sell products. It doesn’t have to be a retailer either maybe a podcast recorded at a restaurant could work as a way to promote that place.
I’m wondering how you can improve the tents for the refugees. The idea I had was if material access to wood and tools could be provided. With this they and others could construct tent platforms and other supportive solutions. I think it makes sense to make use of the ingenuity of the refugees.
What if you can charge a battery by an alternating current directly. What would such a battery construction look like? At what frequencies would this work? Where would you use it? Would it carry any advantages from todays batteries?
The idea is to improve blogs for those writers who want to create more interesting articles by involving more people in the writing process. Other peoples opinion and input can take time to get so maybe this could be solved with a site on the Internet. Here you post a draft of your post and then collaborate. For those who help out there could be a credit list together with the writers name. I believe this a good way for those who participate to learn how an article could be put together and maybe get more people blogging.
Here I want to take advantage of knowledgeable people with experience of entrepreneurship for generating new startups. My hunch is that there exists people who are very good at finding business ideas. Why then can’t you have a company that generates startups? The main idea is then to train and as a company provide lots of different ideas that are likely to succeed. Then match those business ideas with the best and most motivated people. They in turn will do their best to make them into successful businesses.
In a previous blog post I wrote that you could probably filter out and practice the most commonly found difficult words before you read the book. Here I’m going to present an idea where you combine the latest technology to practice reading. The idea is to encourage and challenge yourself by reading together with others offline and online. Offline you can mix every other page with an audio book. It doesn’t have to be a commercial recording. A teacher might record her own voice reading the book. So here you have the student reading one page and the next page the teacher recording is playing. If you have a tablet then it makes it easier and can then be adapted to the students individual pace. For those who want more you could have a internet community where you connect with a group and take turns reading online. Maybe something like Google Hangout could work for this. I think this could be an awarding experience for the readers as well as the listeners.
This idea is meant as an increase in cooperation among poor store owners and other product producers. Basically the idea is that the producer who might be a refugee can still benefit from stores or little shops by renting space in those. This way they need not do big investments. They can sell their gods in a shop anyway.
Here I’m going to write about one of the many possibilities that exists in making textbooks digital. The idea is simple. In a digital textbook for tablets one could have for each theory section or for certain exercises a link to a hidden collection of frequently asked questions and answers. Those questions could very well be crowd sourced. The idea is then that you first read the theory and if you don’t understand you go to the corresponding FAQ for that section. Hopefully this would make the book easier to understand and let you study better.
