Speculation – Does There Exist Feeling Based Optimization?

This idea is inspired by painting. My experience is that when you paint. You make alterations based on feelings. If the drawing doesn’t feel quite right you make an alteration until everything feels right. Thinking about feelings. Everything we do generates a feeling within us. I don’t think that it’s just for show. When a person designs a product he looks at it and feels. If he then makes a prediction on what the changes should be to amplify that good feeling. Is he not optimizing that product with a feeling as a base? My idea is then that we might be able to capture or computer recognize that feeling and others with machine learning. Then we could have the computer make optimizations based on feelings. That is. The computer makes alterations to the design to maximize the specific “feeling” we want.

Idea – Healthy Cookie Singles As Candy Replacements

The idea is very simple. Divide the large cookie containers into singles or dual cookies wrapped in some foil paper. Sell this beside the chocolate bars and you can get a much healthier alternative to ordinary candy. Healthier because of the real ingredients like real sugar and flower. I believe this will be a win win for the consumers and for the cookie manufacturers. Single cookies will yield more money per cookie and the consumers will feel more healthy eating a non chocolate health-cookie.


Idea – Make Your Own Language Training Program On The Smartphone

The need for education for refugees are large. With the Internet we now have vast amounts of learning opportunities in the English language. I have read that smartphones are rather common in refugee camps. Then why not make e-learning programs on the smartphones for English learning. The programs need not be very complicated. A simple web page with a little JavaScript will do. I made such a “program” that takes a local text file with Arabic and English words and lets the user train by translating these words. The “program” or web page is loaded in the chrome web browser. Just enter file:///sdcard/ and find the index.html file from there. With a text editor on the phone I don’t need a laptop. Just use that for making new collections of words. I took the Arabic translations from google translate.

Idea – Basic English Training From Running Linux

As a non native English speaker learning English is one of those things I really appreciate. The idea I had was if the operating system could help in the English training. Could we have a language setting that mix English with the persons native language? I’m thinking several advantages. One problem I’ve encountered is to support a person who has set his system language to something I don’t understand. It would be good if we both could see what’s going on in those situations. With this getting over that first hurdle learning your first words would be much quicker. Also searching for a problem solution is generally done in English so here there is a problem if the system is only in the native language. You don’t know exactly what English words were used.

Another related idea to get more translations for software in Linux would be to let the user input their own translated words. This would mean that for every English word you see in the program you can add a translated word.

Idea – Webpage eSport?

I don’t know if this idea will work. But if it does it will give the youth something useful later in their life. What if they could compete with each other making webpages. The idea is to make a website from instructions and images. Upload that to some server and compare it with contributions from other people or groups. With free online MOOC’s and courses the required knowledge is obtainable. The Internet will be in the hands of the youth. Why not make it very good.

Idea – Solar Powered Thermo Electric Cooling For Drinking Water In Emergencies?

To battle heatwaves we need to drink plenty of water. In my experience cold water is much more effective. Then why not use our wits to create cool water. I’m suggesting a product that uses a simple peltier device powered by a solar panel that is then used to cool water for drinking. I’m not thinking of a portable refrigerator. I guess you can make it more effective by creating a contact area with the water and the peltier device.

Example image just to clearify the idea. Here maybe one should use two water containers. One that you cool and one water container you transfer heat to. Here the chilled water container is small compared to the heated container. Showing both ideas.

Idea – Product Exchange To Enable Stores With New Products Every Week

The idea is simple. Maybe there should exist cooperation among small businesses for certain products sold in our stores. The idea is that the stores could with some help have a section of new products every week or so. If so. People passing by would be inclined to go into the store just to see whats new. I don’t know how to implement this idea but maybe one could rotate popular products among several stores not located close to each other.

Idea – Bug Fixing Exercises For All School Subjects?

The idea is simple and obvious. I believe you need to isolate and train specifically the task of correcting errors in all subjects for the students. Not only in the combination with finding the solution from scratch. The idea is that they could gain ”bug fixing” knowledge which they could then use for their own advantage when finding a solution to a problem. Similarly to be able to collaborate better with others. The thought error with todays system is that the errors encountered by the students are there owns. Meaning they will loose training on many errors they don’t usually make themselves.

Idea – Phone Feature

Taking inspiration from the Yota phone being a dualscreen phone maybe its enough to have two displays. One big and one little. The idea I had was if you could have scrolling display like the old mp3 players had as the little low energy information display and one ordinary big display. The reason is that people don’t need to turn on the phone to check the time, the latest sms or some other frequently checked information.

Idea – Big and little display /

Idea – Smart Tools For The Benefit Of Vulnerable EU-Migrants?

In a previous blog post I was wondering how vulnerable EU-migrants could be helped. I think I got the starting answer. Information. I believe those EU-migrants can benefit from information to them and from them. If they get access to devices like smartphones we could make Internet software that could benefit them. What if they could post suggestions themselves to the challenges. If you have a dedicated employment service in the phone maybe they could find employments, job and language training.

Idea – Memory Game

As a twist on the classic memory game I came up with this idea. The idea is to pair two images on the tablet or phone let the computer check if they are related. A simple relation could be the same face or an object that has been rotated. I think maybe this could help older people who have trouble remembering faces. They could just pair the same person from two different angles. Anyway I think it could be a fun game to create.

Philosophical – Freewill

A post for the possible existence of human freewill

Even if absolute freewill is impossible. Nature can simulate it. Meaning that we need not look at an absolute perfect version of freewill. Just one that can improve, change or evolve. This means we are looking for a practical freewill system that helps make choices that are somewhat efficient. A system that makes choices coincide or at least not go against your will. Since otherwise it will be very inefficient.

Where does freewill come from?

Humans can act upon information. That doesn’t mean I think we all would behave ideally. This because its a difficult problem to generate good information to act upon. But its probably better to rely on your own generated information then to always be dependable on what the outside world will give you.

A guess. Everything that can be recognized can also be generated

I therefore wonder if the choices we make growing up are evaluated. If they are then its possible to classify them into groups under some circumstances. I’m sure there there will be a group that we can say are examples of human freewill. Since the neural net can recognize these type of choices then it can generate them as well.

What about the illusion of free will?

Because you can recognize the feeling of freewill. Your brain can use this feeling as the target for your neural network (similar to a machine learning target). If  your actions then helps generate this feeling over a longer period of time. Then you can say that your actions follows your will and there is no illusion. Possibly you need to generate the “idle” state in the brain also with the freewill feeling as a target.

Free will despite all kinds of resistance

Idea – Smart Random Numbers

This is another food for thought item.

I think there is potential improvement in the random number system we use for searching solutions to various problems. We humans are not very good at outputting random numbers. I think we just output educated guesses. Then perhaps we could innovate the random number system to a smart system. That is we use educated numbers generated from a neural network. The strategy could then be to progressively work down from educated guesses to completely random numbers. Use only complete random numbers when a solution is not quickly found.

Idea – Engage Parents With Own Pace Free Online Courses

The idea is simple. To give every child equal chances in school why not have national online courses in the subjects for the parents. I believe you can gain a lot for the child by refreshing the memory of the parents. The courses should be free massive open online courses which they can take at their own pace. That is without any start dates or other deadlines. Here it would also be possible to adapt the short courses with useful information for parents.

Found A Good Idea – Borrow Home Internet From The Library

Found the article Borrow the internet? Berkeley Co. library offers new service . Here people could borrow the Internet. I think this could work for Sweden also. For especially elderly people that are afraid they don’t know how an Internet dongle or portable wifi router works. They could get help in the library and try for free at home. Borrowing a free Internet dongle for some period could perhaps then help to close the digital divide. I believe this is important for them because if you are connected you are less alone.

Idea – Handmade 3D Effect Paintings?

The idea is simple. With the help of computers it should be possible to select the 3D depth of the layer in which you will paint. Different layers of the drawing could then have different depths and thus display a 3D-effect when combined. The display could be done on big 3D TV screens until something else is invented. I haven’t seen such a computer program but maybe in the future we could have 3D-effect art.

Guessing – A Cool Idea?

The idea I had was to use a device like a Peltier generator together with an air conditioner. The problem I have living in an apartment is that its hard to install conditioners. If I could convert some of the heat energy from the air conditioner outlet to electricity. I would have an easy way to transport and burn that energy in electrical wires outside the apartment. If this worked I would be able to install many small conditioners in each room so that I don’t need to cool the whole apartment. Just the room I’m in. Further if we do not place restrictions like direct current does on electricity maybe one can achieve a higher efficiency from the Peltier generator. Maybe there should exist a device that generates an alternating current from heat. Perhaps you would not put restrictions on the frequency either.

Idea – Empower Refugees With Smart Markets


Feel free to modify or just take inspiration from this idea. To empower refugees why not give them the opportunity to create a market for their products. Here they could use todays modern tools to enhance the traditional market. For instance one could with little money create a wifi web server with software that would make this market more consumer friendly. The costumer could get various information this way. What products are the most popular at the moment and possibly get sms notifications for when the products they requested are available. Here maybe one could make delayed deals. A notification is sent later if the seller accepted the bargained price. I think you can do the same for time of the day dependent prices also. Here you could send a notification when the price of the products which the buyers are interested in have gone down. The idea is that the product sellers collaborate trough the software so that the consumers only have to connect to one of a few servers but still be able to access all the sellers. You would not need the Internet for this to work. The smartphone can connect to a wifi webserver without the Internet. Even if the market would not cost millions of dollars the virtual space created in the phone could be quite advance.


Philosophical – Thinking In Terms Of Believability

I wonder if we make it to hard for our brains thinking about theories. Either in biology or physics. What if we aim to show why the theory is believable. I think this would give room for further advancements and if there exists something like truth recognition in the brain. This would then give perspective and relax the brain in trying to understand it.

Idea – Spoken Questions In Schoolbooks

I’m thinking an easy solutions to teacher anxiety. The problem where you under perform because your not used to getting questions verbally. Would be to incorporate audio version of written exercises or questions in digital textbooks. The audio version is not meant to be exactly as the text. Here you can use your imagination to guide the student. Give them a sense of direction, encourage or otherwise engage them. I found a good set of information which could be used to enhance the spoken questions on ”Using Questioning to Stimulate Mathematical Thinking” – .

Idea – Should There Exist Two Person Team Employments?

I was wondering if you can make the job market easier and more efficient. As of now you get a job as a single person. What if you could team up with a friend and apply for the job? I’m thinking this might work for online jobs. The employer would get the benefit of a pair that has already worked together before and enhance each others abilities. Since they get graded as a team it would mean that they would teach and improve each other. Why put a team together based only upon their skills. With two person employments you know they can already work together. If the had the same skills they could ask each other. I think this would greatly improve the quality of the work.

Update :

Thinking about this further. Could this idea be used to employ more people in wheelchairs?

Great TIP – Try zRam In Ubuntu MATE For The Raspberry Pi2

Here is a really good tip. Since the Raspberry Pi2 only got 1GB memory I thought why not try compression. After installing zRam on my Ubuntu MATE setup I can only say WOW. That is some difference. The Iowait is gone. No waiting even with lots of tabs in the browser and multiple programs running at the same time. Everything feels snappy and the Pi2 gets to be even more awesum.

Info taken from

installing in the terminal :

sudo apt-get install zram-config

Turn the RPi2 to a proper desktop with Ubuntu MATE and zRam
