Facebook fired for asking questions about Trump's remarks


WASHINGTON: Facebook has fired an employee who criticized Facebook founder Mark Zuckerberg for remaining silent over US President Donald Trump's controversial remarks.

An engineer named Brandon Dale was recently fired by Facebook. Dell also announced on Twitter that he had been fired by the company. Despite the recent social and political turmoil in the United States, Facebook owner Zuckerberg has remained silent, and Brandon has publicly criticized him.

Brandon was dissatisfied with Zuckerberg even after Zuckerberg did not respond to the anti-apartheid 'Black Lives Matter' campaign in the United States. Along with Brandon, Facebook has laid off more than a dozen employees. Out of which 6 are engineers.


Zuckerberg has been criticized for political reasons for his silence on the anti-racism movement. Facebook has fired Brandon. But the reason for his dismissal has not been disclosed.

Protests have erupted in the United States over the murder of George Floyd, a black man, by a white police officer in Minneapolis. President Trump has tweeted against the protesters. But Twitter has been checking facts and hiding Trump's latest remarks. Facebook owner Zuckerberg has been criticized for remaining silent.

Use of AI (Artificial intelligence) in Nepal

Artificial intelligence


According to researchers, AI does just what it is designed to do. Scientist Khanal says, ‘Ordinary people cannot recognize the whereabouts of the head and hands of a child in the womb during the ultrasound. If there is software for that, it can be recognized. When trying to post a photo on Facebook, Facebook tries to identify the person and tag them.

How will Artificial Intelligence (AI) affect human creation once it begins its creative work? This question has been raised since the advent of AI as the latest development in science. The question was raised in public when China's state-run Xinhua news agency unveiled an AI news presenter in November 2018.


In 2016, Hanson Robotics, a Hong Kong-based company, built the robot, Sophia. He was even granted citizenship by Saudi Arabia in October 2017. Two years ago, Sofia was brought to Nepal for the UNDP's 'Technology for Public Service' conference, with which many Nepalis interacted. "As Nepal has made good progress in the field of technology, if it is adopted in the right way in the coming days, it can make a big leap forward in development," said Sofia. This sparked the debate on AI in Nepal.

The AI ​​Debate also got a place in the Nepal Literary Festival held in Pokhara in the last week of last December. The debate, entitled ‘Artificial Intelligence and the New Definition of Art’, raised concerns about whether humans would be driven by AI, but researcher Dr. Vinod Bhattarai tried to convince people that the use of AI will make them comfortable.

Before that, the first international AI conference was held in Nepal in October. Research and experience on AI and its various dimensions were presented at the conference organized by British College. The AI ​​conference is being organized by the government next July. Organizing committee member and scientist Suresh Manandhar informed us that the purpose of the conference is to raise investment by giving information about its possibilities and challenges. According to him, international level researchers will participate in the conference.

 

Use of AI in Nepal


Of course, AI is a new topic for Nepal. There has not been enough research on this. The Nepal Applied Mathematics and Information Institute for Research (NAMI) is conducting research in Nepal. Similarly, an organization called Fuse Machine is active in producing and researching AI engineers. The organization, led by researcher and scientist Sameer Maskey, is also active in creating various apps.

Researchers estimate that AI can be effective in Nepal if used properly. As Nepal is multilingual, the use of AI in language translation can be effective. Khanal has a special opinion. He says AI can also be used to study the effects of climate change and human migration. Another area he sees potential in agriculture and health. "At a time when there is a shortage of manpower in agriculture, small robots can be built and used for mining and other purposes," he said.

What is AI?


The founder of Artificial Intelligence (AI) is American computer scientist John McCarthy (1927–2011). He was accompanied by Alan Turing, Marvin Minsky, and Alan Newell Herbert A. Simon. McCarthy coined the term "artificial intelligence" in 1955.

It includes software that can perform intellectual and emotional tasks just like humans. AI includes software that smells, touches, listens, sees, and imagines. Google's language translation software is one of them.


According to researchers, AI does just what it is designed to do. Scientist Khanal says, ‘Ordinary people cannot recognize the whereabouts of the head and hands of a child in the womb during an ultrasound. If there is software for that, it can be recognized. When trying to post a photo on Facebook, Facebook tries to identify the person and tag them. That kind of identification is done by software. But the software does just that. '

Development of AI


From the 1950s onwards, scientists began researching and using machines that could speak, hear, think, and imagine like humans.

In the 1990s, AI was used in chess, where human intelligence was used extensively. Then I started thinking about the unlimited dimensions of AI. However, the development of AI accelerated only in the decade of 2010. Deep learning and machine learning also became ubiquitous in the 2010s. Just as a small child learns things when he or she grows up, the machine also has a human-learning AI phase, called 'machine learning'. Deep learning is used to teach something in depth.


Autonomous driving is the latest achievement of AI. It includes the concept of driverless driving. Similarly, chat but AI is also being used. This AI is considered to be effective in informing the service recipients about their services.

Along with AI, researchers have started thinking about Artificial General Intelligence (AGI) and Super Intelligence. Under this, a machine that can think beyond the human mind is being conceived.

Challenges and possibilities in AI


Surveys have made many feel insecure and challenged by the development of have been made public. The opinion that employment will collapse after all the work is done through AI has also come together. However, the bright side of AI is very visible. Researchers say that this will help in the rapid development of sectors such as trade, education, and transportation. Scientist Khanal says, ‘There are many companies that have achieved success by combining AI with entrepreneurship. In the context of Nepal itself, by using it, Nepal can participate in the fourth industrial revolution and accelerate the pace of development.

A new era of sound recording

A new era of sound recording


Worldwide, thousands of songs are recorded and produced in a single day. So sound recording has become a natural process for us. It can be felt that the world of recorded sound is different now. The new technology of sound collection that has come in recent times is introducing novelty in the recording method. Looking back to 1983, it can be said that there has been a revolution in music or sound recording and new instruments of preservation.

Since then, along with CDs and digital audio, new devices have gained momentum. The 'MP3' that came in 1996 came into vogue for a long time. Its use can still be seen. It is considered a quality and reliable record medium. Digital monitors in 1999 added another feature. It included both a media player and a library. Developed by iTunes, the company allows users to download, organize, and store a myriad of files.

Major Transitions, which came out in 2006, set huge tower records, which played an important role in saving and archiving. Nowadays, various means including memory, pen drive, or online apps are used to save audio. With the development of YouTube, the content has also started to be kept safe on YouTube. We have no problem finding a wide range of sound recording and protection options. However, going back to the early stages of song recording, we find it strange.

To get back to the early days of the record, it's important to know about the world's first recorded song. Edward Leon Scott de Martinville, a French citizen, first invented the phonograph, which he invented.

On April 9, 1860, he recorded the sound. The first recorded song in French was "Junelima" (A Clear the Le Lun). The phonograph converted sound into a picture of waves, engraved on paper or glass. However, its sound could not be heard and could not be reproduced. After the invention of the phonograph, soundwave graphics could be transcribed into audio files that could be heard again.

The invention of the phonograph can be traced back to the invention of the recording technology in 1877. Since then, various technologies have been developed including wax cylinders, flat discs, RAC Victor, mass production, radio broadcasts.

With the advent of the digital age, the sound recording has gone through various eras. Experts say that sound recording has been started to be heard again in the future. According to scientists, the sound is an intangible thing. The various methods and steps for recording this abstract thing were as follows:

The ecstatic and mechanical age


This recording method was used from 1890 to 1925. During that time all sound recordings were made by mechanical means without microphones or electrical amplification.

Before 1925, for sound recordings, singers and instrumentalists performed live performances in front of the horn, from which sound waves were collected and transmitted to the diagram. The energy of the sound waves vibrated the diagram.

This caused waves to form on the empty 'wax' rotating cylinder or disk. This method had no electronic control. At that time, recording songs using this method was considered a great skill. However, the record range of this recording method was limited.

Electric age


During this time electrical recordings appeared as a result of scientific experimentation and innovation. This electrical method 'replaced' the ecstatic method.

It was first used by the Columbia Record Company and the Victor Talking Machine Company in 1924. This improved the sound quality. At this stage, the sound was recorded on an electronic device, using a variety of instruments, including microphones and amplifiers.


Electronic microphones have dramatically changed the way singers perform, and electronic promotions have had a profound effect on many areas, facilitating development in radio, public address systems, and electronically.

At the same time, practical methods of providing sound came into use. The technology at this stage was such that audio sources could be heard simultaneously.

One of the most famous examples of composite sound at this stage is the famous 'Tarzan Scream' made for a series of Tarzan films starring Johnny Weissmलरller. However, this technology did not change the group's direct performance. It lasted until 1945.

Magnetic age


After the invention of the magnetic tape recording in Germany in 1950, a new change took place in audio recording. This is the technology used in the period from 1945 to 1976.

The technology was invented in the 1930s but was limited to Germany until the end of World War II. The magnetic tape took another leap in audio reliability. Magnetic tape has rapidly become the standard medium for audio master recording in the radio and music industries since the 1950s and led to the development of the first hi-fi recording for the domestic market.


Multitrack tape recording was developed for music. Disc for sound ended. The magnetic tape also brought the original shape of the recording process. This made the recording possible for a much longer period than before and made it much easier for recording engineers.

Easily manipulate, edit, and record disc sounds captured on tapes made the impossible possible. Large "virtual" sounds and devices were created in the 1950s. Magnetic tape promoted the rapid expansion of popular music and other genres.

Digital is the new age


Sound has been collected through digital technology since 1975. The current phase is in the digital age, which is the biggest leap in the history of recording. The Japanese electronics corporation Sony first used the PCM encoder PCM-1 audio unit in the 1970s.

In 1979, unlike previous technologies, it captured a continuous analog recording of sound. Many short-term hybrid studios and consumer technologies appeared during this period. For example, digital audio tapes or data, which began recording digital signal patterns on standard magnetic tapes.

Sony introduced the development of its new digital recording system with Philips using today's most advanced consumer audio format Digital Compact Disc (CD).


By the end of the 20th century, compact discs had almost completely dominated the consumer audio market. The rapid development of computing technology in its last decade marked the most important era in the history of audio recording, greatly reducing file size.

Extensive licensing of audio and other digital media files began to take place. Free -ware technologies such as Napster and BitTorrent upload and download large volumes of digital media files at high speeds. Fast internet signals and data storage have consistently improved devices.

Music broadcasting services have gained popularity since 2000. Streaming audio does not require listeners to download or own audio files. Streaming services offer an alternative way to listen to music. At the same time, more and more voice recording technologies are being introduced.

The growing trend of e-books

The growing trend of e-books

With the development of printing presses in the world, letters printed on paper began to be read. In the last eight centuries, many printing presses have opened in the world, and millions of books have been published. People became accustomed to reading published books. However, with the development of technology in recent times, the style of reading books has changed. The number of people reading books on laptops, tabs, and Kindles has increased more than the number of printed books. That is, readers are attracted to e-books.

Geographer Professor Pitamber Sharma, who has been reading books continuously for six decades, has changed his reading style. Sharma, who reads books printed on paper, now studies through Kindle. "I've been reading my favorite book on Kindle for a few years now," says Sharma. He has experience.

Sometimes they move books found online to laptops or smart TVs. And, they read books while they are asleep. Sharma, who has read more than a dozen books through Kindle, is currently reading Pankaj Mishra's Age of Anger and The John Adams' People, Power and Profit.

Authors Ujjwal Prasai and Ganes Poudel also read books online using modern technology such as mobile phones, tablets, Kindles, or laptops. Prasai, who has been reading the book through Kindle for 7 years, says, "The Kindle given to me by a friend while studying in India has been very effective for me."

Author Poudel, who used to carry previously printed books in his bag, does not forget to carry a tablet or Kindle when he goes on a journey. "The Kindle has become so much easier to read," says Poudel. "The Kindle has become my friend since I don't have to carry a lot of books and read wherever I can." He understands that it is effective.

Not only Sharma, Prasai, and Poudel, but also writers and readers have recently started using technology for study. Mainly with the development of the Kindle, the style of reading books has changed.


What is Kindle?


The Kindle is an electronic device developed by the Amazon company, used to read books and textbooks online. Users can purchase and download books as well as newspapers, magazines, websites, blogs, and electronic editions. You can also study books online by downloading the PDF.

The Kindle version of the e-book can be purchased from the Amazon website. Most users connect to WiFi to download books. The Kindle can store more than 1,400 books. The user claims that reading the letters on the Kindle is as enjoyable as reading the hardcopy.

The Kindle makes it easier for the reader to bookmark than a printed book. Because Kindle has an automatic bookmarking facility. Kindle also makes it easier to find the meaning of words you don't understand as you read. It is also becoming popular among the readers as there is a password facility for the security of the book.


History and status of the Kindle


The Kindle was launched on November 19, 2007. Over 12 years, it has come up with various developed versions. Kindle can publish a book in 5 minutes. The book will be available at Kindle stores from June 24 to 48. Authors receive 70 percent of the royalties from the sale of books published by Kindle.

In an interview with The New York Times on December 5, 2009, Amazon CEO Jeff Bezos stated that e-book sales would account for 65 percent of revenue. The remaining 35 percent said there would be an agreement between the publisher and the author. Amazon reports that the Kindle version of British author AL James's novel Fifty Shades of Gray has more than doubled in print sales. Between 60,000 and 100,000 books are published each year in the United States. More than half of them are published online.

According to statistics, Kindle currently has 48.5 million books stored. In which you can find various rare books including world-famous and best sellers.


Where unlimited books hang


At one time, Professor Pitamber Sharma had built a library of printed books at home. Now he has started distributing those books. "With tens of millions of books available online, there is no need for a library at home," he says. "I have started donating my books to the village library." The practice of establishing traditional libraries has decreased now that ample books can be collected online.


More than 2.6 billion e-books are stored in the Good Readers e-library. Founded in 2007, the e-library is considered to be the largest in the world. The library, which currently has 90 million readers, has published reviews of more than 90 million books. It even has the facility to read hundreds of books for free.

The Gutenberg Digital Library was established in December 1971 by American author Michael S. Hart to facilitate the production and distribution of e-books. In which more than 60 thousand books and documents can be obtained free of cost.

In the online library called Open Library, millions of books can be read with various documents including picture books, fantasy, biography, science. In the Jet e-library of the 'B OK CC' site49,059,396 books and 77,194,989 articles can be read.

Similarly, books and articles from around the world can be read and published from many e-libraries including Open Library, Book Bone, Free eBooks.

Writers earn millions from e-books


Many writers in the world earn millions by writing. In which the role of online publishing is important. Amanda Hawking, a 35-year-old American author, has made a lot of money from online publishing. At first, the publishing house refused to publish his book. I didn't even have the money to publish it myself. She later launched her book online. He has sold more than 1.5 million books online. Since then, she has written 17 novels. "I never thought I would make so much money from an e-book," she says.

Stephen Ladder, a well-known British writer, is also one of the highest-paid writers in e-book publishing. Last year alone, he earned 11,000 euros a month from e-books. HP Mallory, an author of Urban Fantasy and Paranormal Adventures, sold 70,000 copies in the first two months of last year. His book is one of the best-selling e-books in a short period. Authors like John Locke and Oliver also make a lot of money through e-books.


Reference to Nepal


Readers of e-books are increasing in Nepal. However, most Nepali books are not available in e-books. Author Kailash Rai says that it is compulsory to read Nepali books on the hardcover. She says, ‘I read foreign books online. Nepali books do not have this facility. '

Nepalis living abroad are facing more difficulties as Nepali books are not available online. "It is difficult to send Nepali books abroad," says storyteller Denman Gurmachan. "If there was an arrangement to read online, Nepali books would be accessible to all."

This is not to say that Nepali books cannot be read online. Some limited books on Nepali literature, non-literature, and curriculum can be read and listened to at Library.org. Open Learning Exchange Nepal (OLE Nepal) has been providing e-library since 2009. So far, 6,800 books, 2,319 audiobooks, and 561 videos have been stored. Recently, some publishing houses have started online editions. But that is not enough.

History of the printing press


The writing was not a tradition when human civilization began. It was customary to listen and recite what the ancestors or teachers said. The script was invented when the process was cumbersome and undocumented. Initially, the writing was done on stone and leaf bark through signs. Tustin Lun, a Chinese citizen, invented paper with the help of cotton and linen. Then limited and clear block printing started in China. A wooden block was made for this. The world's first book, The Diamond Formula, was published in China in 650.

The world's first printing press was established in China, which used wood paper. According to a study, the art of making a paper has spread from China to Europe via Arabia. Some researchers have speculated that the printing press may have originated in Europe in the 15th century. According to him, before 1440, there were a few thousand manuscripts in Europe. Later, German goldsmith Johannes Gutenberg founded the press for the first time.

Gutenberg is said to have invented the one-handed machine for improving grape-squeezing machines. Handpress is an improved form of it. Which was made in Colombia, USA? It is only after the commercial development of the printing press in the world that it is found that it entered Nepal. This is the first time that a Colombian printing press has entered Nepal. It is called Giddhe Press in Nepali. The then Prime Minister Jung Bahadur Rana had brought the press to Nepal from the United Kingdom in 1908 BS.

He had the press given as a gift by the then Queen Victoria of the United Kingdom to be attached to his own palace in Thapathali. V&J The press is called 'Vulture Press' in Nepal as it has the shape of a winged vulture on the front of the machine which is written 'Physicians Makers'. Before that, I had to travel to India to publish a book.
