Eelo New Open Source Mobile OS by Mandrake Linux Creator

eelo is a new mobile OS based on open source Android distribution LineageOS. Its creator is trying to build an ecosystem which is free from Google and Google related products

eelo is a new project launched by Gael Duval, the creator of now defunct but once hugely popular Mandrake Linux (later known as Mandriva Linux). As per Gael, this is an attempt to free us from corporates like Google and Apple invading our privacy and selling our data to advertisers. 

I’m not happy with this situation because iOS is proprietary and I prefer Open Source Software. I’m not happy because Apple is getting crazy with their latest products. They are more and more expensive, and not really exciting.


Also I’m not happy with Google and others. They have become too big and are tracking us by catching a lot of information about what we do. They want to know us as much as possible to sell advertising. Like millions others, I’VE BECOME A PRODUCT OF GOOGLE.


I want to stop that, at least for myself. People are free to do what they want. They can choose to be voluntary slaves. But I do not want this situation for me anymore.


eelo will be more than just a mobile operating system. It will have its own associated web-services such as email, cloud storage, online office tool etc. eelo is intended for people with a better respect for their personal data and privacy. But at the same time, it wants to give the end-user all the tools that a standard mobile OS provides.

eelo is forked from LineageOS, an open source Android distribution. LineageOS can run mainstream applications so it will be used to put together a consistent mobile and web system.

The project is called ‘eelo’ after eel fish because eels are small fishes that can hide in the sea. That’s symbolic of privacy.

Oh! don’t expect it to be 100% perfect from the privacy point of view at least in the beginning but Gael thinks it will be better and better with each iteration.

“We’re 7.6 billion people on Earth and I don’t see a good reason why they would all accept to have their private data cached by Google, Apple and a few others,” says Gaël Duval, the Europe-based project founder of Eelo. However, Duval told that his approach will be realistic and pragmatic, which means he is not going to make Eelo completely isolated from the rest of the ecosystems.

The first level of his privacy-enabled phone would mean “no Google inside”. “Google is absolutely everywhere. Even in Chromium (the open source release of Chrome web browser), there are low-level code that is sending what the user is doing to Google,” he explains, adding that if “you use a Google DNS resolver such, Google is catching some information about your activity on Internet”.

The same with Google Search, Gmail, Google Maps, Google Drive and so on. Similarly, each time to install an application and or even use an app that is using Google services, you are sending some information to them, he adds. “Apple is catching your data (even health data) and using it for their business, and also they have a deal with Google to have their search engine by default for the user.” Duval promises alternative services “that better respect the user privacy”.

Elon Musk Unveils Falcon Heavy Rocket Photos Ahead of Maiden Flight

SpaceX founder Elon Musk unveiled a tantalizing first glimpse at his company's new megarocket — the Falcon Heavy — which is expected to launch on its maiden flight next month. 

In an early morning Twitter post, Musk revealed several views of the new rocket under assembly inside SpaceX's hangar at Pad 39A of NASA's Kennedy Space Center in Cape Canaveral, Florida. The images show stunning views of the Falcon Heavy from above and one imposing shot of the rocket's 27 first-stage engines, nine on each of its three main boosters.

SpaceX's Falcon Heavy is a heavy-lift launch vehicle powered by two first-stage boosters from the company's Falcon 9 rockets and a central core booster that itself is a modified Falcon 9. The rocket will stand 230 feet (70 meters) tall when complete and is designed to launch payloads of up to 119,000 lbs. (57 metric tons) into space.

The Falcon Heavy is the most powerful U.S. rocket since NASA's Saturn V moon rocket and is capable of launching twice as much payload as the current record-holder, the Delta IV Heavy built by United Launch Alliance. SpaceX's rocket is also designed to be reusable, with the three core boosters built to fly back to Earth and land like SpaceX's current Falcon 9 rockets. The company test-fired the Falcon Heavy's core stage for the first time earlier this year, in May.

Musk has said that Falcon Heavy's first payload will be his own midnight-cherry-red Tesla Roadster, launched on a trajectory aimed for Mars orbit. However, Musk has said that there's a fair chance the rocket could fail on its debut test flight. The Falcon Heavy is expected to perform its first static-fire test on Pad 39A by the end of 2017, SpaceX representatives have said. 

SpaceX also plans to use a Falcon Heavy and Dragon space capsule to launch two passengers around the moon by the end of 2018.

See the Brightest Supermoon of 2017

On the night of December 3 2017, sky-watchers around the world will get a chance to revel under the first—and last—full supermoon of the year.

This December 2017 full moon officially occurs at 9:17 p.m. IST (15:47 UT) on the 3rd. Less than a day later, the lunar orb will make its closest approach to Earth for the month, coming within 222,443 miles of our planet at 3:30 p.m. ET (9:00 UT) on the 4th. That means the moon on the day of December 4 will appear about seven percent larger and 16 percent brighter than usual.

A supermoon is the popular term for a full or new moon that coincides with the lunar orb making an especially close approach to Earth. The moon’s orbit around Earth is not a perfect circle but is somewhat elongated. That means the moon changes its distance to Earth by a few thousand miles over time, reaching a closest point (perigee) and a farthest point (apogee) in any given month.

Technically, this will be the fourth supermoon of the year, but it’s the only one we’ve been able to see with naked eyes. That’s because the other three supermoons of 2017 coincided with new moons, when the lunar disk shows a totally darkened face.

Tree Grows 40 Kinds of Fruit

Sam Van Aken, an artist and professor at Syracuse University, uses "chip grafting" to create trees that each bear 40 different varieties of stone fruits, or fruits with pits. The grafting process involves slicing a bit of a branch with a bud from a tree of one of the varieties and inserting it into a slit in a branch on the "working tree," then wrapping the wound with tape until it heals and the bud starts to grow into a new branch. Over several years he adds slices of branches from other varieties to the working tree. In the spring the "Tree of 40 Fruit" has blossoms in many hues of pink and purple, and in the summer it begins to bear the fruits in sequence—Van Aken says it's both a work of art and a time line of the varieties' blossoming and fruiting. He's created more than a dozen of the trees that have been planted at sites such as museums around the U.S., which he sees as a way to spread diversity on a small scale.

Tomorrow Time Stops for a Second

Why Time Will Stop For a Leap Second

Time will stop on June 30, but don't worry: It will only be for a second. Researchers will add a sliver of time—a leap second—to the world's clocks.

Just as leap years keep our calendars lined up with Earth's revolution around the sun, leap seconds adjust for Earth's rotation. This kind of fine-tuning wasn't much of an issue before the invention of atomic clocks, whose ticks are defined by the cycling of atoms. Cesium-based clocks, one kind of atomic clock, measure the passage of time much more precisely than those based on the rotation of our planet, so adding a leap second allows astronomical time to catch up to atomic time.

Atomic Clock

An atomic clock based on cesium ticks away at the German National Metrology Institute in northern Germany.

Most of us won't notice the addition, which happens at 23:59:59 coordinated universal time (UTC), or 7:59 p.m. ET, unless we deal in timescales shorter than a second, or if we use a computer program that crashes because it can't handle the leap second. It's happened before: The 2012 leap second brought down Reddit, Gawker Media, and Mozilla.

"It's a major interruption mostly because there are a lot of systems that aren't prepared to handle the leap second correctly," says Judah Levine, a physicist at the National Institute of Standards and Technology (NIST) in Boulder, Colorado. Leap seconds occur irregularly, which makes it hard for programmers to test their fixes, he explains.

Levine is responsible for making sure the nation's timekeepers at NIST can handle the leap second. When it comes time to adjust their clock, NIST will transmit 23:59:59 UTC twice, Levine says. "Once when that time arrives, and once again for the leap second."

So 6 p.m. mountain time—the NIST offices in Colorado are seven hours behind UTC—on June 30 will be stressful. "There's a full panic mode just before and after 6 p.m.," he says.

Even if all goes well during the addition, Levine and his team are usually greeted the morning after by a deluge of emails concerning various problems.

Not everyone recognizes the leap second, although Apple does so on its devices. Google mobile devices sync with internet time services that are usually tied to atomic clocks. But "if you have a standard Windows system, [it] just ignores the leap second," Levine says.

Financial markets like the New York Stock Exchange also take the leap second into account. The exchange will close the market a half hour earlier than normal, at 7:30 p.m. ET on June 30, to help their systems deal with the addition.

IRNSS-1C launched by PSLV-C26 successfully placed in orbit

Indian Regional Navigation Satellite System (IRNSS) 

IRNSS-1C is the third navigation satellite of the seven satellites constituting the IRNSS space segment. Its predecessors, IRNSS-1A and IRNSS-1B wre launched by PSLV-C22 and PLV-C24 in July 2013 and April 2014 respectively. IRNSS-1C has a lift-off mass of 1425.4KG. The configuration of IRNSS-1C is similar to the of IRNSS-1A and IRNSS-1B. the satellite has been realised in less than six months after launch of its predecessor.


IRNSS is an independent regional navigation satellite system being developed by India. It is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary, which is its primary service area. IRNSS will provide two types of services, namely, Standard Positioning Service (SPS) and Restricted Service (RS) and is expected to provide a position accuracy of better than 20 m in the primary service area.

Mars Mission Mangalyaan India comes last but still defeats the toppers - US, Russia, Europe

angalore, Sept 24: India's mission Mars -- Mangalyaan entered the Mars orbit, the latest entrant. It created history on Wednesday, Sept 24. The fact, which shocked many, is that Mangalyaan is the cheapest mission for Mars so far. Mangalyaan, which means "Mars craft" in Hindi, took off from the island of Shriharikota, off India's eastern coast, 10 months ago. The 3,000lb (1,350kg) device first headed for an elliptical orbit around Earth, after which a series of manoeuvres and short burns of its rocket engines sent it on towards Mars. India defeated US, Russia, Europe, the other countries which had already placed their satellite on Mars orbit. While big Asian giants -- China, Japan failed to join them, India joined the elite club of Martian explorers with United States, European Space Agency and former Soviet Union. 

Here are the comparative costs of travel to the red planet in recent years:

NASA's Maven USA Nov 18, 2013 Sept 21, 2014  -- $671million

Mars Express Orbitor Europe June 2003 December 2003 --- $386 million

Nozomi Japan July 1998 Mission failed, Dec 2003 --- $189 million

Phobos-Grunt With Chinese satellite Russia Nov 2011 Mission failed --- $117 million

Mangalyaan India Nov 5, 2013 Sept 24, 2014  --- $74 million

Want to ward off allergies Pick food up off the floor says scientist who claims our obsession with cleanliness has weakened our immune systems

Picking food up off the floor, keeping a dog and regularly kissing your relatives are some of the best ways to ward off allergies, according to a leading immunologist.

Professor Graham Rook also advised that when a baby spits out its dummy, mums should just lick it clean and put it straight back in their mouth.

Modern society has become so obsessed with cleanliness that we no longer come into contact with some of the crucial bugs that keep our immune systems working well, he said.

Just eat it: Modern society has become so obsessed with cleanliness that we no longer come into contact with some of the crucial bugs that keep our immune systems working well, a scientist said

It means that when the body meets a substance it does not know, a ‘trigger happy’ immune system will over-react, attacking the body in the process.

Professor Rook, speaking at the Cheltenham Science Festival last night, said the issue was a ‘generational problem’, with children in Britain and other Western nations more susceptible to allergies than older people.

Professor Rook, a professor in medical microbiology and immunology at University College London, said a simple way to keep the immune system working well is to pass germs between family members. That includes not rushing to sterilise a dummy when a baby spits it out.

Professor Rook said: ‘If a parent picks up the dummy right away and sterilises it or replaces it with a new clean one, that child has a considerably greater chance of having eczema and asthma.

‘But if you are the sort of parent that sucks it clean and it sticks it back in the baby’s mouth, then it actually protects them from allergic disorders.

‘It’s because they have better bacterial development in the mouth and gut. And this is what protects them.’

Conditions such as asthma, hay fever and food intolerances are on the rise.

Hospital admissions for allergic reactions jumped by 8 per cent last year, following a steady increase over the past three decades.

Data from the Health and Social Care Information Centre published this week shows there were 20,320 admissions in 2012/13 compared to 18,860 in the previous 12 months.

GSLV-D5 India's first Indigenous Cryogenic Stage GSAT-14

GSLV-D5 with Indigenous Cryogenic Stage successfully launches GSAT-14 from SDSC SHAR.

GSLV-D5 is the eighth flight of India’s Geosynchronous Satellite Launch Vehicle (GSLV). It is also the fourth developmental flight of GSLV. During this flight, the indigenously developed Cryogenic Upper Stage (CUS) will be flight tested for the second time. GSLV-D5 will launch 1982 Kg GSAT-14, a communication satellite, into Geosynchronous Transfer Orbit (GTO). After reaching GTO, GSAT-14 will use its own propulsion system to reach its geostationary orbital home and will be stationed at 74º East longitude. GSAT-14 will help provide many satellite based communication services to the country including tele-education and telemedicine. GSLV-D5/GSAT-14 mission will be launched from the Second Launch Pad at Satish    Dhawan Space Centre SHAR (SDSC SHAR),Sriharikota. The flight duration of GSLV-D5 is 17 min 8 sec.


GSLV is a three-stage launch vehicle with solid, liquid and cryogenic stages. It is designed to inject 2 Ton class of communication satellites to Geosynchronous Transfer Orbit (GTO). The four liquid L40 strap-ons as well as the second stage of GSLV use storable liquid propellants. GSLV-D5 vehicle is configured with its first and second stages similar to the ones flown during earlier GSLV missions. The third stage is the indigenous cryogenic stage. The metallic payload fairing with a diameter of 3.4 metre is adopted for GSLV-D5. S-band telemetry and C-band transponders enable GSLV-D5 performance monitoring, tracking, range safety / flight safety and Preliminary Orbit Determination(POD).

Indigenous Cryogenic Upper Stage

Indigenous Cryogenic Upper Stage

A Cryogenic rocket stage is more efficient and provides more thrust for every kilogram of propellant it burns compared to solid and earth-storable liquid propellant rocket stages. Specific impulse (a measure of the efficiency) achievable with cryogenic propellants (liquid Hydrogen and liquid Oxygen) is much higher compared to earth storable liquid and solid propellants, giving it a substantial payload advantage. However, cryogenic stage is technically a very complex system compared to solid or earth-storable liquid propellant stages due to its use of propellants at extremely low temperatures and the associated thermal and structural problems. Oxygen liquifies at –183 deg C and Hydrogen at –253 deg C.The propellants,at these low temperatures are to be pumped using turbo pumps running at around 40,000 rpm. It also entails complex ground support systems like propellant storage and filling systems, cryo engine and stage test facilities, transportation and handling of cryo fluids and related safety aspects. ISRO’s Cryogenic Upper Stage Project (CUSP) envisaged the design and development of the indigenous Cryogenic Upper Stage to replace the stage procured from Russia and used in GSLV flights. The main engine and two smaller steering engines of CUS together develop a nominal thrust of 73.55 kN in vacuum. During the flight, CUS fires for a nominal duration of 720 seconds. Liquid Oxygen (LOX) and Liquid Hydrogen (LH2) from the respective tanks are fed by individual booster pumps to the main turbopump to ensure a high flow rate of propellants into the combustion chamber. Thrust control and mixture ratio control are achieved by two independent regulators. Two gimbaled steering engines provide for control of the stage during its thrusting phase.


GSAT-14 is the twenty third geostationary communication satellite of India built by ISRO. Four of GSAT-14’s predecessors were launched by GSLV during 2001, 2003, 2004 and 2007 respectively. After its commissioning, GSAT-14 will join the group of India’s nine operational geostationary satellites. The main objectives of GSAT-14 mission are:

  • To augment the in-orbit capacity of Extended C and Ku-band transponders 
  • To provide a platform for new experiments.

The cuboid shaped GSAT-14 has a lift-off mass of 1982 kg and the dry mass of the satellite is 851 kg.GSAT-14 structure is based on ISRO’s 2 ton class platform (I-2K satellite bus). The two solar arrays (each with two panels) of GSAT-14 together generate about 2600 W of power, while the light weight Lithium-Ion Batteries supply power during eclipse period. 

Some of the new experiments being flown on GSAT-14 are: 

  • Fiber Optic Gyro
  • Active Pixel Sun Sensor
  • Ka band beacon propagation studies
  • Thermal control coating experiments

Lizard Has One-Way Breathing Hints at How Dinosaurs Breathed

Air flows only one way through its lungs—other than the American alligator, it’s the only other known reptile found to have this trait.

That’s surprising, because the unidirectional airflow of birds was thought to have evolved due to the high-oxygen demands of flight: Instead of being partially filled with stale, depleted air like human lungs, avian lungs contain air with a much higher average oxygen content and are much more efficient at getting oxygen to the blood.

So this method of breathing was generally considered to be unique to both warm-blooded animals and birds.

That changed in 2010, when Colleen Farmer of the University of Utah and colleagues found that alligators breathe one way.

Now, Emma Schachner, a postdoctoral researcher in Farmer’s lab, has added another species to that list.

“Finding this trait in a [cold-blooded] lizard means that warm-bloodedness and unidirectional airflow have no relationship whatsoever,” Schachner said.

As I Live and Breathe

When humans or other mammals breathe, the air flows through the same lung passages during both an inhale and an exhale. As we inhale, the air flows in through our nose and mouth and down through the windpipe, where it splits and flows into a bronchi, or passageway, that leads to each lung.

The airways divide and divide again, each time getting smaller and smaller. Eventually, the air makes it to tiny alveolar sacs, where oxygen travels from the air into the bloodstream.

MOM says bye to Earth

Indian Space Research Organisation (ISRO) has said the Mars Orbiter Mission (MOM) will cover 680 million km with no fuel. The velocity required by MOM to reach Mars had already been imparted during the Trans-Mars Injection.

Now, MOM is cruising with a velocity of 32.8 km/second. MOM is expected to reach Mars in September 2014.

MOM doesn’t require any fuel to travel from Earth to Mars in its Mars-Transfer Trajectory. However, a little fuel was required to correct the trajectory and control the orientation of the spacecraft, Isro said.

On December 11, Isro will conduct the first small mid-course correction maneuver. The subsequent ones will be carried out in April and August next year. “In line with our fetish for jargon, the fancy term coined for these operations is trajectory correction maneuver (TCM)!” Isro said.
