Google's Algorithm for Happiness

Wisdom

Mindfulness Skills Enhance Emotional Intelligence


Chade-Meng Tan, one of the company’s first engineering employees in Mountain View, a few years ago, noticed that several of his colleagues were stressed out and unhappy at work. Hence he decided to work on something in connection with it.

 He convinced his superiors to permit him in creating a course which would teach employees mindfulness skills enhance emotional intelligence and promote well-being and he transitioned to the HR department to run it.

With his employer’s approval he named it Search Inside Yourself, a corny name which also was the title of his book with regards to the course’s techniques. At the festival of 2015 SXSW in Austin Texas, Meng taught the scientifically proven secret of happiness in three easy steps.

Step One – Calm your mind


With the introduction of his first piece of advice, Meng led the SXSW audience through a small collective breathing exercise in order to calm the fluffy particles in the snow globes in our skulls. He believes of finding easy options of taking a pause during the course of the day and be aware of one’s breath.

On a lighter note, he states that if it tends to be too hard then just think about nothing for a little bit. His book provides more details, focusing on what mediation is and how to start practising on it, quoting a study of mindfulness training which reduces reported anxiety by Jon Kabat-Zinn at the University of Massachusetts Medical School. Meng does not seem to be the only one to recommend that meditation and mindfulness is good for mental health.

Matthieu Ricard, the monk, for instance whom the press has named as `the world’s happiest man’, had written a book about himself. There seems to be some evidence that mindfulness could help to fend off negative thoughts and according to a recent review of 209 studies it was found that the practice could help to treat depression, stress and anxiety. It is worth mentioning that handling depression as well as anxiety is not essentially the same as boosting happiness. Meng’s choice of happiness advice seems to have growing scientific acceptance.

Step Two – Log moments of joy


This means saying to oneself while sipping coffee or laugh at a friend’s joke or while purchasing a shirt that `I am having a moment of joy’. When negative things occur in our life throughout the day we simply hold on to them while the good things are more fleeting and momentary.

Meng states that by consciously accepting the good things, we increase our chances and when we reflect on the day’s happenings, we conclude that it was a happy one. The theory of observing positive experiences counterbalances or outweighs negatives, makes instinctive sense. We could relate to the power of single though short-lived event spoiling a whole day but seldom does the opposite seem to be true.

Step Three – Wish other People to be Happy

According to Meng, selfless thoughts are advantageous since we tend to obtain a lot of joy in giving more than in receiving. Meng makes powerful arguments for the - `I think’ self-evident need to pervade your life with compassion but quotes on study on people acting for others, backing his claim that `kindness is a source of happiness’.

Recent research had made attempts in exploring this effect including one by positive psychology researcher Barbara Fredrickson which ended that we require a 3:1 positive-to-negative ratio of thought in order to free our minds from the tar-paper effect of thinking negative. But this study has proved to be debated with some questioning the mathematical claims made in paper.

Snapchat will let Brands Advertise on Your Face

Snapchat

Snapchat – Sponsored Lenses


Snapchat will be launching a new advertising format which will enable brands to advertise on people’s selfies. This features is known as `Sponsored lenses’, a latest attempt in Snapchat in order to get revenue from its audience comprising of the youth.Snapchat has launched its first new lenses feature in September, permitting users to cover animations on their faces comprising of massive heart eyes, wrinkles as well as vomit rainbows.

The lenses feature seems active while taking a selfie. Tapping and holding on the reflected image of the face tends to instantly outline map of it and prompts to pick from eight various interactive filter which ranges from simple Photo Booth-style effects to the ones with animations and sound.

Each new ones tend to replace an old one each day and can be utilised on photos or videos. Snapchat has now signed a number of appealing parties which will be replacing vomit rainbows as well as old people’s faces with sponsored animations. As per The Financial Times, it is said that the first of these lenses would probably make its appearance on the platform in time for Halloween, though there has been no indication on which brands would be on board.

Developing New Sponsored Animation


According to a spokeswoman from Snapchat who informed FT states that `the sponsored lenses enable Snapchatters to express themselves and connect with a brand in a really creative and dynamic way’. Another source had apparently reported that Snapchat has been charging up to $750,000 for brands to reach its whole user-base during the course of a big holiday or $450,000 on any normal day.

Moreover, the addition of sponsored content would be added over the top of selfish with personal snaps that would leave some with a feeling of discomfort. Snapchat would probably be developing new sponsored animation and the FT claims Hollywood studios would probably be the first to sign up.

This does not seem to be the first move into in-app advertising of Snapchat. It had teamed up earlier in the year, with communication super group WPP and the Daily Mail to operate on a content marketing collaboration known as Truffle Pig. Besides this, it has also been trailing advertisements in Discover news services such as CNN and Cosmopolitan since January 2015.

Launched Around Halloween


The latest sponsored lenses would be launched on or around Halloween and the prices would be high according to Financial Times report. Taking into account that Snapchat tends to have hundreds of millions of active users every month, the money could ideally go a long way.

Though there is no information on how different or same it would be to the prevailing lenses, Snapchat would be developing them in-house and according to the report it says that the first would probably be from Hollywood studios. This is the fourth revenue stream for Snapchat, besides Discover and the ads placed in daily stories as well as paid replays.

 However, this seems to be unique from the others and rather than passively observing, sponsored lenses are about engaging with brands which will exactly be in your face. Probably as Snapchat has put it across the Financial Times as `sponsored lenses enable Snapchatters to express themselves and connect with a brand in a really creative and dynamic way’.

System by Affective – Pick up Hidden Emotions


A software has been developed that can sense how much one tend to get swayed by marketing by analysing the face as one watches the advertisements. Ad companies seems interested in assessing the reactions of the consumers to their latest TV spots and this is done by bringing in few customers in the office and pose queries to them.

However, the system adopted by Affective, a start up in Waltham, Massachusetts, has the capabilities of picking up hidden emotions by monitoring face movements. The approach according to Daniel McDuff, Affectiva’s principal scientist enables you to find out what the consumer generally thinks from time to time as the ad tends to run and not what they say once it is ended.

He has commented that that `it provides a way of getting at those more genuine, spontaneous interactions and this is their instinctive response. It is not sent through a cognitive filter where they have to evaluate how they feel’.

The software of Affectiva tends to first identify important facial signs like the mouth eyebrows and the tip of the nose. The machine learning algorithms tends to watch how these areas move or how the skin texture and the colour alter in the course of the video. These alterations are then broken down into distinct expressions portraying shifting emotions.

Focus on Emotions – Surprise/Confusion/Happiness


McDuff together with his colleagues, in a study which had been published recently, has asked 1223 people to give his team access to their home webcams while they watched a series of ads for pet supplies, groceries and sweets.

Prior and after the running of the ads, the subject filled out on online surveys was on how likely they would purchase the products shown.As they watched, the software focused on the lookout for emotions like surprise, confusion and happiness.

The researchers then found that they could utilise the facial data to predict precisely, the survey results of someone indicating that they could depend on the analysis of the computer to know if an ad was successful.

McDuff is of the belief that in the future, the system could plug in TV services like Netflix. He states that one can imagine suggesting TV programmes or even movies which people could watch or ads which they would find enjoyable.

Subtle Disparities in Emotional Responses


The team at Affectiva had accumulated a database of more than three million videos of people of various ages, ethnicities and gender. McDuff is of the opinion that there could be subtle disparities in emotional responses.

For instance women seem to have more positive facial expressions than men. However on understanding the respond of various groups, companies could put together ads which could be fine-tuned for certain audiences. Similarly, the data could also be helpful to advertisers to pull their adverts to draw closely the emotions of the viewers.

Michel Wedel, studying consumer science at the University of Maryland in College Park states that automated emotion analysis systems seems to be promising enabling advertisers to cut down an ad, to find out what exactly works and what does not. He adds that it is particularly unobtrusive and does not depend on introspection or recollection.

To do the research through the viewer’s home webcams is an added advantage though it would not be fool-proof. People could be eating a sandwich or turning at the computer or turning their head and so unable to classify their emotions consistently.

Making Liquid Fuels From Sun And Air

Liquid Fuel for Internal Combustion Engine – Inefficient


Liquid fuel for internal combustion engines is inefficient due to various explosions leading to kinetic work to be done as well as loads of heat together with various other reasons. With the same quantity of energy put in an electric motor and an internal combustion motor, it could produce more usable work for the earlier than the later.

 Moreover, electric motors tend to operate at the same efficiencies over a range of speeds where internal combustion motors need more messing around to alter the speed, besides the torque. Torque is probably at the core of coolness for several vehicles enthusiasts.If one could get the hot car or a motorcycle to go from zero to fast within a second or two, it is considered to be cool even if it tends to have no day to day application.

An electric motor has that potential and internal combustion motor need to be a super motor to perform well. Besides, liquid fuels tend to spill and smell bad and there could be chances of explosion. Electricity on the other hand has its own limitation. We would need to change most of the moving things, in the long run, like vehicles, planes etc. to electric, though fuel would still remain to be important to certain extent.

Liquid Fuel in Flying Machines


Mission critical backup generations which are not needed much but are life or death,are apparently run best on liquid fuels stored long term such as the one at the South Pole research station or in any hospital. We would eventually see electric airplanes though for long time we would apparently have to put liquid fuel in flying machines.

A present issue of Science has a write-up on recent research on machine that takes sunlight, CO2 from the atmosphere and some water producing burnable liquid. The write-up conveys about several alternative research projects which have approached this issue with various levels of success that is very early research though promising.

The job tends to boil down to run combustion in reverse, inserting energy from the sun or other renewable into chemical bonds. According to John Keith, chemist at the University of Pittsburgh in Pennsylvania states that `it is a challenging issue since it is always an uphill battle’. It is what plants tend to do in making sugars they require to grow.

Methanol – Converted to Variation of Products


However, plants only convert around 1% of the energy into chemical energy and to power the industrial society, researchers need to do much better. Keith compares the challenge to putting a man on the moon. The simple method tends to be almost the same in all cases. One could take CO2 molecule and change it to CO by knocking off one Oxygen atom and then combing the CO with H2 to get syngas that can be changed to methanol.

Methanol is a type of alcohol which can be converted into a variation of products. Same process in the widespread use utilises fossil methane as a base molecule rather than atmospheric CO2. A paper is to be published in Advanced Science informing the process which utilises CO and H2 together with photovoltaic generated electricity.

This focuses on a band of sunlight on to a semiconductor panel converting 38% of the incoming energy into electricity at a high voltage. The electricity is shifted to electrodes in two electrochemical cells. One tends to split water molecules while the other splits CO2. Most of the remaining energy in the sunlight is trapped as heat and utilised to preheat the two cells to hundreds of degree, which helps to lower the amount of electricity essential to split water and CO2 molecules by 25%.

Unhackable Kernel could Keep All Computers Safe from Cyberattack

Boeing

Unhackable Operating Systems – Kernel


An autonomous helicopter gunship which seems to be flying over a military base in Arizona suddenly tends to lose radio contact. This is due to hackers taking control of an on-board computer. New Scientist can reveal that US Defense Advanced Research Projects Agency – DARPA utilised a similar scenario in a drill to test the cybersecurity of an unscrewed Boeing Little Bird helicopter.

Inspite of the hackers having unbound access to the computer, and making great attempts to disable the helicopter, crashing the computer, they were unable to disrupt the critical system. DARPA which is focusing in developing an unhackable drone by 2018 as a part of its High Assurance Cyber Military System – HACMS programme, the drill seemed to be successful.

It is said that the software which had kept the helicopter’s computer secure was at the core of its operating system and could be the most appropriate thing what could make everything from pacemakers, insulin pumps, power stations, cars immune to hacking.

Gernot Heiser from the newly formed Australian national research agency, Data61 had commented that his hope was that in 10 years, anything which could be security critical would be running on the system or some other one built on the principles established. One of the predecessors had developed the crucial component of the unhackable operating systems – its kernel.

Central Staple of the Operating System of the Computer


The kernel is said to be the central staple of the operating system of the computer. If the hackers tend to gain access to it, for instance, they could perform actions which could be meant to be prohibited such as turning a mobile phone into a signal jammer. Heiser’s team last year had proved mathematically that their kernel is unhackable.

The kernel, known as seL4, has some highly secured properties and can do only do what it is developed to do. Its code cannot be altered without permission and its memory together with the data transfers cannot be read without permission. Earlier version of it was known as OKL4 which is now on millions of smartphones. Heiser has informed that the two features support seL4’s security and one of it is a new way of isolating data within the kernel.

 However, the main development was making the code proficient of being checked mathematically. The other kernels may tend to have these properties though it would be impossible to know precisely without mathematical proof according to Heiser.

seL4 – Keep the Systems Separate


Two of the hackers in the month of July had played a prank by accessing remotely the computer of a Chrysler Jeep, making it stop abruptly on a highway and then crash it into a ditch. The consequences were that the company recalled 1.4 million vehicles.

The question that arises is – could seL4 prevent such an incident in the future?Heiser informs that one cannot stop hackers from gaining access to things like a car’s entertainment system, if it communicates through Wi-Fi. Hackers often tend to use non critical systems as a springboard to critical areas such as steering as in the case of the Jeep prank.

However, the seL4 kernel could keep the systems separate. According to Heiser,there are attempts occurring to roll this out to cars in order to protect them. It seems a big deal for cybersecurity according to Iman Shames from the University of Melbourne in Australia who states that there are ways to attack hardware even if the software is secure. Hackers could be capable of tricking the sensors of a device or jam incoming communication or any other signal which could be quite overwhelming.
