7 easy tips for cheaper flight tickets





here are some very easy tips to cut down flight costs.

4 simple car safety tips.

Here are some simple tips for your and your co-passenger safety when it comes to driving around. While the technology outstretches itself to provide us with cushions like ABS, EBD, Air bags, etc, old school seat belts still form the major backbone of safety. 

1. An impact at even 48kmph is same as falling from 3rd floor of building(9m)*

Similarly, an impact at around 103 kmph is same as falling from 14th floor and hitting the ground!!!

NEVER think that you need seat belts only at high speeds. Even at low speed collision it saves from injuries. In fact at lower speeds the air bags may not deploy and at high speeds, the seat belts provide you with most of the barrier and aid the air bags considerably and technically they are much more important than any other thing, including air bags. Simply put : always wear a seal belt. 

*You can punch in any height to check the impact velocity here. Note that typical building floor is around 3m high. https://www.angio.net/personal/climb/speed.html 

2. Always, adjust the head restraint to cover your head. 

This will prevent severe head and neck injury in case your vehicle turtles up(goes upside down). The importance of this small little barrier to your safety is such that it's a mandatory requirement in many races around the world to pass a severe impact test otherwise car is deemed unfit for racing. Also never remove the head rest completely, as that may lead to severe fatigue injury to your neck even in course of regular driving.

3. Always be in control of your speed. 

Follow speed limits for your own as well as safety of others. Most of the crash tests including the famous European NCAP tests are done in too optimistic circumstances*. In real world, you can never be sure of safety even with all the advertisement promising you 6 air bags and collision protection systems. Most of the accidents at lower speeds are minor while most high speed collisions make their way into statistics. This does not mean that you need to drive at a snails pace but try to stay within the speed limits and drive in your comfort zone. Added benefit is having lower bills for your fuel costs.

*NCAP tests are done at 64kmph with static target which is 'similar' to 2 cars colliding each other, each travelling at 32kmph.

Don't talk on phone while driving. 

This is lots of potential for safety concerns. Distraction is one of the causes of accidents and could be easily avoided. Even speakerphones can be dangerous as physically you may have hands on the wheel but your mind is somewhere else. Your reaction time may increase or you may not see an approaching danger. Also, the habit of texting or working with an app while driving is even more dangerous than talking over phone. Secondly, and less importantly it's the cellular radiation buildup so you should avoid prolonged conversation while inside your vehicle.

It's best to park and get outside the car and finish your call. This may sound strange but making a call inside your car induces the buildup of cellular radiation inside the car cage, way beyond the SAR limits at times. It exposes not just you but others into harmful radiation and any conversation beyond a few seconds should be avoided.

Get outside and talk>Park and talk>Speaker phone >  handset conversation while driving > Any hand held activity with phone like texting. 

Lower your window pane while reversing and parking in closed spaces.  

At times, you need aural feedback in addition to the visual feedback, especially while reversing your car. The mirrors don't show you everything and there may be parked vehicle in your track right in the blind spot or some people in the worst case. Being able to listen for people calling for help could be essential in these cases. At times I have saved a poor dog that would be sleeping under the wheels or prevented hitting a randomly parked two wheeler outside my initial sight when I heard the cry for caution.

I had witnessed a potential death at an instance. My brother in law was reversing his car from the parking lot, right when he started to reverse, a small girl came in her kid scooter and fell collided with the car. It was invisible as she was too low from the line of sight of the rear view mirror. As the car kept on reversing, she came under the wheel and was about to be crushed. Thankfully by this time, we rushed to gesture him to stop immediately and take the car slightly forward and pulled the kid out. She survived with minor injury to the legs.

Easy fix for Marshmallow slowness and battery drain



Once people updated to the new marshmallow, problems started coming in. If you feel stuck with this new update, here are some tips and recommended apps that could help you somewhat.

One of the main issues plaguing the users is battery drain. People have complained about up to 20% less battery backup after the update has come up. There are of course some easy fixes to these battery drain problems. However for someone who is not a power user things have gone downhill in this department. If you are a power user then you could install a custom CPU clock management app like No Frills CPU. It could help you get better backup.

Another complain that is common and also a major pain for users is the sluggishness of the phone. Right from Nexus to Moto G, many phones have become slow. Some speed loss came just after the update and further slowness came after few days of usage. Try to keep all of the  media contents on the external memory card. This can free up your internal memory and keep apps faster. Secondly you could kill apps running in the background using Hibernate app that can freeze auto start apps.
Third common problem is that of app close. Many apps are randomly closing. It's frustrating to see apps freezing without any valid reasons. Another problem is of memory management. KitKat was King of memory and since then things have not been good. You can overcome this with huge amounts of RAM but for phones with 1GB or less RAM, keep using KitKat based ROM. There is no direct way to address this issue. If you know of some way, please post in the comments below.

Final tip is to wipe your system cache. The process will vary from phone to phone but you can Google the process for your specific model.

What are the world's top 10 selling phones?

Surprisingly, none of the phones launched in the last few years feature in this list. Another surprise is absence of "Apple" from the list. Another interesting find is that none of these are smartphones or even a feature phone for that matter.



What is clear is that today the manufacturers face stiff competitions and cannot eat up a large part of the market share. Another reason for today's phones not being on the list is that. Phones from each manufacturer have internal competitions and there are so many Galaxies that you can't count on your fingers.

Lets give you the list of top 10 phones right away:


Top 10 best selling phones in the world
Rank Model Release year Sales to date
1 Nokia 1100 2003 250m
2 Nokia 1110 2005 250m
3 Nokia 3210 1999 160m
4 Nokia 1200 2007 150m
5 Nokia 5230 2009 150m
6 Nokia 6600 2003 150m
7 Samsung E1100 2009 150m
8 Nokia 2600 2004 135m
9 Nokia 1600 2006 130m
10 Moto RazR 2004 130m



You can see clearly that Nokia takes 8 positions in the top 10. Yes, there was a time when it did seem invincible and that was not too long ago!

Closer to today, Samsung Galaxy S4 sold over 80 million phones and i Phone 5 model had over 70 million buyers around the world.

Xiaomi In Ear 2016 review



Xiaomi has been known to introduce disruptive products offering an unmatched cost to quality. Taking the journey forward from the cellphones, they have made a range of products right from power banks to wrist band to earphones to even air purifier.

When they introduced the first version of Piston earphones, it was an instant hit. Mass oriented sound signature with plenty of bass, excellent finish and durability most importantly it was priced much below it's class. It was sold like a hot cake. In the Piston 2, they revised the sound signature to have a more controlled bass(better quality than quantity) with added benefit of a spacious sound stage. This became the new budget favourite at Head-fi. Post this there was another leap forward with introduction of the hybrid model which was the cheapest hybrid earphone ever made. Sadly it was not a perfect implementation of twin drivers and was not liked that much. Piston 3 changed that with significant shift towards a flat sound signature(no bass bloat), using a single high quality dynamic driver. This review is about the latest edition of MI IEM which was labelled simply as "MI in ear". Only buy from official website at from Mi India. There is usually no discount on this site for these earphones and buying from any other source may be risky as there are counterfeits of Xiaomi everywhere.



The design

This IEM is a design marvel. Getting a prize from Red Dot for it's remarkable design later last year, this earphone is one of the best engineering earphones we have seen lately. It comes in a beautiful white package that opens easily once you remove the transparent round stickers holding it together. Inside that you will find a plastic case, which is another highlight of the design. You will find the earphone wrapped in a silicone organizer which sits over the array of 3 sized eartips. These tips are beside the pair of M sized ones already mounted on earphones. 



The instructions to recoil the earphone on the silicone organizer is shown in inner side of the white package. 

The earphone cable is made of kevlar up to the split, where there is soft silicone coated bi wiring. The right earphone cable has the microphone which is discussed in microphone section below. It is made of brushed aluminum and quality is remarkable at any price point.

The eartips are angled which are done to improve the sound staging, making the earphones sound more 'spacious'.

The diaphragm is made from a sandwich of metal(probably Beryllium) and two layers of PET. This is done to get a good response both in lower frequencies as well as higher frequencies(at least in theory). For those who think this "aerospace grade" metal as claimed by Xiaomi is out of sci-fi fantasy, it is not. However other companies such as Sony and Vsonic have been using exotic materials for making earphone diaphragms such as Bio-cellulose.


The sound


This in ear has a very flat sound. Which means that the bass, vocals and treble are all well balanced out without emphasis on one single section. Initially out of the box they sound a bit boring with touch of bass boost but using them(search for earphone burn-in) for about 30-50 hours will make them sound natural. Right now it sounds quite balanced after the initial burnin is over. The strong point of sound is that nothing is bad in this earphone signature. Treble does not hurt with sibilance, bass is not bloaty, mids are not subdued. However the minus point is that there is no particular area where this earphone shines. It may sound boring to those coming from bass heavy Piston 2 or even other earphones. There is dearth of detail in the higher frequencies which sound a bit dull. This would not be problem if you are upgrading from any bundled earphones or cheaper ones but prominent if coming from more premium earphones/headphones. Overall it gives a pleasant presentation and at this price it is as good sound as it can get. Definitely better than all mass produced earphones at this or lower price.

The microphone unit


Besides a good sound quality, this is another selling point for this earphone. In fact some testers specifically liked this because it's controls in the mic unit make it a complete android headset. 


There are three unlabelled buttons which can be used for both calling as well as for controlling music player. It is extremely convenient to switch back and forth tracks(double/triple click on middle button), pause and resume(single Middle button click) and increase or decrease volume (the outer two buttons). These controls come handy while commuting. 

Please note that some feature like volume control will not work in iPhone. Some android phones too are not fully compliant to volume control. This works perfectly on all Xiaomi phones. 

Apart from music controls, it also controls the calls. As seen in the above image, you can recieve, reject calls, put on hold and mute microphone. 


Final verdict

Xiaomi in ears are perfect companion to your phone and shall work flawlessly for a long time, given the build quality. Sound is good but beaten by audiophile grade earphones like Dunu Titan, Soundmagic E50, E80, Vsonic GR series, etc. However these are not headset with controls and cost three to eight times the price of Xiaomi.
