Thanks


For KodiCast,


Is the Android version on Google Playstore?


How do I also get the PC version?

You have to go to the Kodi website for PC version and the Google Playstore for the Android version.

Do you need a job to be successful in life? What happened to being your own boss?

Everyone is not destined to succeed in business, and I do not need a job and if I did it will not be one that discriminates age, gender or tribal affiliations.

By George Dvorsky

Using a computer powered by an off-the-shelf Intel Core i5-6600 processor, a FedEx employee from Tennessee has discovered the largest prime number known to humanity. At 23,249,425 digits long, it’s nearly a million digits longer than the previous record holder.

For those of you who failed or have long forgotten grade 3 math class, a prime number is any number that can only be divided by 1 and itself (e.g. 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, etc.). It’s a freaky quirk of the Universe that has captivated mathematicians for centuries, as their appearance in the roll call of all integers defies prediction (though biases have been detected in the distribution of consecutive primes). Finding prime numbers thus requires a bit of trial-and-error, patience, and a lot of computing power.

The new record-holding prime number, dubbed “M77232917,” was discovered by Jonathan Pace, a 51-year-old electrical engineer living in Germantown, Tennessee, on December 26, 2017. It was discovered as part of the Great Internet Mersenne Prime Search (GIMPS), a group that does exactly what its name implies. Mersenne primes—named after the 17th century French monk Marin Mersenne—are a rare class of primes that are one less than a power of two, expressed as Mn=2n-1. In this case, the new prime was calculated by multiplying the number two 77,232,917 times and then subtracting one (277,232,917-1). The new prime is the 50th known Mersenne prime.

M77232917 contains 23,249,425 digits, which is practically impossible for the human brain to comprehend. You can download a zip file of the number here, which busts open into a simple text file nearly 24 MB in size. Here’s an itsy-bitsy, teeny-tiny glimpse of the first few digits of the number:

4673331833592310999883355855611155212513211028
17714495798582338593567923480521177207484311099

52492202867874992249236396330386193059511707705
22850356011779638644050954128274109548519743273
55101432575324997699380819164104077499060702708
51317808544314827192879270515747600591825011224

You get the point.

According to GIMP, that’s big enough to fill an entire shelf of books totalling 9,000 pages. Or put another way, “If every second you were to write five digits to an inch then 54 days later you’d have a number stretching over 73 miles (118 km)—almost 3 miles (5 km) longer than the previous record prime,” writes GIMP.


Pace, a long-time math enthusiast and a current employee at FedEx, does charity work as a SysAdmin, running Prime95 on all his PCs and servers; Pace is one of thousands of volunteers who are using free GIMPS software in the effort to continually find larger and larger prime numbers. The PC that Pace used to find the prime number required six straight days of computation on a quad-core Intel i5-6600 CPU to verify it.

Indeed, the discovery of new primes is no small task; every candidate prime must go through the time-consuming and rigorous process of being cut-up by any potential divisors. Once a candidate prime is discovered, it has to be verified by outside sources. In this case, the prime was independently verified by four different programs running on different hardware configurations:

Aaron Blosser verified it using Prime95 on an Intel Xeon server in 37 hours.
David Stanfill verified it using gpuOwL on an AMD RX Vega 64 GPU in 34 hours
Andreas Höglund verified the prime using CUDALucas running on NVidia Titan Black GPU in 73 hours
Ernst Mayer also verified it using his own program Mlucas on 32-core Xeon server in 82 hours. Andreas Höglund also confirmed using Mlucas running on an Amazon AWS instance in 65 hours.

The quest to find more prime numbers may seem frivolous, but they hold practical applications as well, such as the generation of public key cryptography algorithms, hash tables, and as random number generators. Further work into primes could also tell us a bit more about mathematics and why it’s so damned good at describing the universe. And as Carl Sagan speculated in Contact, transmitting streams of consecutive primes could also be used as a way of saying “hello” to an alien civilization.

As exciting as this discovery is, the Holy Grail of primes is yet to be found: a prime number containing 100 million digits. The first person to find this elusive number will be awarded $150,000 by the Electronic Frontier Foundation. Good luck!

Correction: A previous version of this article mistakenly calculated how the new prime was reached, sorry about that.

I want to download a CAST-SCREEN App for Tablet-to-Computer

Any Suggestions?

I use Kodi and LocalCast

Meaning anybody still jobless and above 30 is doomed in Nigeria

Cheap, problematic car without a second-user value; not the kind anyone should be proud to boast of or show off. Thing is, he bought it second-hand, so it's pretty much valueless, I look forward to helping him push the car on Lekki Road.

Nah only you get eyes my brother...if to say nah 505 I for say e get collectors value.

Answer these questions!
1.Are you a deltan or live in delta state?
2.Do you live in warri?
3.Do you live in Udu local government area?
4.Do you live in either in Aladja or Ogbe-ijo community?


If your answer to any or all of these questions is No, then just read and Waka pass. I reside in Udu local government and can authoritatively tell you that Ijaws from Ogbe-ijo community has been attacking Aladja community for some time now.

Have you seen an Ijaw attacking or did you hear stories?

Bollocks! Abroad is not heaven...and this story reeks of made up bullshit

Bollocks!

I doubt this story...and would advise others to do same. Nah so recently someone tried pithing the ijaws and itshekiris.

It will cost 6 million naira to build 5 bedroom bungalow.

Thanks man

I thought these lugubrious issues ended in 2017?

Let them increase jaré we are already paying 250.

The dividends of military dictatorship of which our honourable president was part of back to back...

How much will it cost me to build a 5 bedroom bungalow in Bayelsa State.

Somebody is up to no particular good...
