15 Crore Lines of Code: The Hidden Digital Engine Powering Your Car and Bike.
you will get to know such technology facts about which you would not even have 0.01 idea Digital Ocean of 150 million lines of code 15 crore hand written codes that keep bikes and cars on road. You know the vehicles that you ride daily like your bike or your car, have millions of lines of code in them.
For example, there is ECU inside the bike, electronic control unit, which powers the bike’s AVS, brake system, traction control, fuel etc. Many people are curious to know how many lines of code are there. So, your two-wheeler bike uses approximately 1 million lines of code. There are 10 lakh lines of code in its programming.

But the amazing fact was not this. The amazing fact is that in the control of cars, in the control of four wheels, the capabilities of the car like AIDS, connectivity and other safety features, there are 150 million i.e. 15 crore human written codes in it and the amazing thing is that the 15 crore codes in a car are the highest.
The fighter jets also have around one or two crore lines. Now after hearing this, you might have this question in your mind that the code is not written again and again. So yes, it is true that it is engineered once and of course it is copied and this is the reason that it takes so much time to bring a car model.
The Secret Computer Hiding in Your Wallet: How Credit Cards Boot Up Like Mini PCs.
I bet you don’t know this fact. Your card like credit card, debit card or you must have seen a chip in the driving license. All such cards are small. Seeing this, common people think that there is a chip inside it, it must be some electronic thing, but the thing is that these cards are a complete computer in themselves.
It has a processor inside it. Just like your mobile has a processor of megahertz or gigahertz, similarly it also has a processor and just like there is a file system in a computer, folder files, similarly there are literally files inside it. There is a folder inside the files. Data is there, everything is there, the processor of these cards usually runs at 4 MHz and just like your mobile has 10-12GB RAM or 5-6GB, similarly the RAM of these cards is between 1kb to 8kb, it is so less because that much RAM is required to power it and its ROM size is RAM 2, so the ROM part is from 64 KB to 512 KB.
now the question may be coming in your mind that the cards in which we keep the purse do not have battery, so how will it run if it is a computer, then this is the thing here, when you use that card, swipe it, then it boots up completely for a second and remains on and all the things are running like a normal computer, it boots up in a few milliseconds and as soon as the card is removed, it shuts down immediately and if this question is coming in your mind that
how do the wireless cards work So the wireless cards and the payment taps work with the help of magnetic field. So, it takes power from the magnetic field and gets booted up for a few seconds.
Midway Mind-to-Voice Tech: Speak Without Speaking Using Just Your Thoughts.
I am telling you to say ‘L’. So, you will speak after thinking.
So, when you speak, there is a whole process behind it which is going on. You think that Apple will come. So, this was possible because the brain sent such an electrical signal here which is making you speak. So, there is a technology to capture this electrical signal on the way itself. So, those people who have become dumb in an accident and are unable to speak, they can also speak just by thinking.
Whatever they think, that signal will go here and they will not be able to speak because they are dumb. But, capturing that signal midway and making them speak through the computer’s speaker is the technology. And this is called Sab Vocal Recognition Technology which works by detecting signals, send to vocal cords.
From Ceiling Fans to 300 Billion RPM: The Mind-Blowing Speed Limits of Human-Made Machines.
Look, there are so many machines in the world, the motor in it. It rotates at a revolution per minute or rotation per minute which is called RPM. So, I am revealing to you the RPM of many things. For example, a car engine rotates at 1000 RPM in idle state, which means that a car engine rotates 1000 times in a minute and see in a second, when the car engine is in high speed, it reaches 7000 RPM.
Your motorcycle engine can also go up to 11000 RPM because its size is small. Washing machine 1600 RPM. Ceiling fan. The fan that is rotating above you rotates at 400 RPM. Just look at the electrical drilling machine, it rotates at 3000 RPM. Hard disk 7000 RPM. Wind turbine rotates at 20 RPM. Tortoise jet engine at 20000 RPM.
Here an interesting question arises, what is the highest RPM achieved by man using technology? So, this will blow your mind. Fastest The rotating machine ever recorded was achieved in 2018 by the research team of PURDUE University. 300 billion RPM is a 300 billion RPM machine, actually that means 300 crore rotations, 300 billion, in one minute and this was achieved by a nano particle which was suspended in a vacuum and it was a particle of nano centimeter which was made of silica and in the entire history of earth, the rotation of any one thing is the highest and this is what has been achieved. 300 billion RPM.
Goodbye Dystopia: Artificial Leaves Are Here to Save Our Future with Oxygen.
The scenes of dystopian future that we see in films, that means a future of earth in which there are no trees or plants, only darkness only. You must be watching such movie scenes, but I have brought good news for you, take this sweet and eat it that actually our world can never become dystopian the way it is shown in the movies.
Why is it so because science is guaranteeing that trees and plants will not be destroyed. What is the guarantee of science? What happened is that many such types of leaves have been made which produce oxygen by using only sunlight and water, that means actually the way a leaf of a tree works to keep the air clean, an artificial one has been made like that.
So, the thing is that at any time trees get destroyed due to the wasteful work of any human being, by chance even if the natural trees get destroyed, then by planting artificial ones we will at least be able to keep the air clean. Actually, these silk leaves absorb CO2 and release oxygen in the same amount as an actual natural leaf release.
So, guys, the dystopian future has been finally prevented.
The Silent SMS You’ll Never See: How Your Phone Can Be Tracked Without You Knowing.
This invisible SMS of your mobile is very dangerous and probably the big agencies would not want me to tell you this, but a type of SMS exists which is called silent SMS and this is used by law enforcement agencies to track anyone’s phone. What happened is that when any SMS is sent to you on your phone, then it is sent to you by the law enforcement agencies.
When it comes, you come to know that an SMS has come. Yes, normally there is a kind of SMS which is not visible in the phone but is received by the phone’s network and it is called stealth ping or silent SMS which does not notify the user and you will say that this is a violation of privacy. No, law enforcement people are allowed to use it in majority of countries and when anyone takes a SIM, he agrees that he is not keeping his location private because technically if you are using a SIM of any company, then you are agreeing to share your location.
Because wherever you are, by taking your phone, where is your nearest tower, your approximate location can be found out from that. In simple words, this is often done through stealth SMS only. An SMS which will come to your phone and you will not even know about it and this is not some common thing, it is not discussed much in India but you If you search a bit on the internet, you will find that this is a much-debated topic.
From Touchscreens to Electroceuticals: How Phones Killed Calculators and Tech Is Entering Your Bloodstream.
Look, the revolution of modern phones came around 2010 when new screen touches were coming out. At that time, screen touch used to be a term called cool. So, you know the reports on Edge.
By 2012, the sales of calculators all over the world declined to 90%. That means, most people started using calculators in their phones and the need for physical calculators ended. And by 2015, the sales of wrist watches dropped from 60% because these are tools that are always present in phones.
That means, the revenue of billions of dollars’ worth calculator producing companies went down drastically.
