How’s life without social media?

Social media has now become a crucial part of everyone’s life mainly youngsters nowadays. In this big world where all that we are worried about today is how better we can portray ourselves on Instagram, Facebook or other social networking sites. Living without one of them would be really very awful. Right? Agreed, as social media now is extensively used by everyone from youngsters to adults and we tend to post each and every activity we do on the same. From drinking our morning coffee to hanging out with friends at night we like to share everything. Well enough of thinking of how we spend our time on social media, let’s take some time to imagine and examine life without it. It would definitely differ from how we live now. Most of the interaction throughout the day would be in person. We would waste less time surfing on the internet and engage more in conversation with others. We would be less worried about how our Instagram Passwort Hacken looks like; maybe we would accept our self as we are as we won’t get a chance to envy others for how fantastic their profile is on social networking sites. So yes there would be no more daily uploading pictures of you or how you carry out your day. It means that no more waiting for approval on your daily feeds by getting likes comments from your friends. There would be no need to work so hard Make your profile appealing to others. As in real life, we are captured by the real human eye which needs no filter.

We all would be freer to just be our self and also enjoy the moment we are living in rather being busy in clicking pictures to show it up on social networking sites. We would interact with others more as there would be nothing we would keep fidgeting with. Life would be simpler maybe because we would not have to manage completely two different worlds together that is the real and the virtual world. It would mean expressing what you feel verbally to your loved ones instead of posting those awful kinds of stuff on Facebook and Instagram. We would communicate with others which would sharpen our communication skills and also would be able to meet the real person behind the screen. We would make better and long lasting connections.

Aren’t you also checking your notification simultaneously while you’re reading this if not definitely keeping a note at it? So yes there would be no more checking up phones the first time in the morning and the last time you go to bed as there would be no more fear of missing out something.

Life will be more peaceful like that, won’t it?

Wondering about how scary or how peaceful your life will turn? You don’t need to. Because at the same time we should always remember that social media is made for us and we are not made for social media. So always keep in mind to monitor yourself to spend less time and make the most of it by taking the positive aspect of the same. When social media has so many negative points it also has some of the useful features which had made life easier and better for many for eg. Instagram bloggers or Influencer. Every coin has two sides; Social media also has the same. It’s on us to use it in a judicial way and yes always keep in mind never let it control us in any possible way.

The transparency of Netflix. How the platform works

Netflix is the best-known multimedia content platform in the world that aims to position itself as an alternative to the worrying piracy of series and movies, offering flat-rate access to all its contents without a limit for a very competitive price. For 3 weeks, this platform is now available in Spain where we can access its complete library of series and movies for less than 10 euros per month, however, do we know how this platform works for servers?

Netflix is not a new platform but has been in the market since 1997. Since not long ago, those responsible for it began to open up to more services with which to offer their content to different countries in the world (each country with an own catalog), currently reaching more than 50 countries around the world.

The company, since its inception, has always been very transparent in its operation. Although a complete guide-summary with all the technical aspects of its operation has not been published, it has been providing information every so often, whenever the opportunity arose, about how the platform was built. The Scalescale portal has decided to collect all this information to be able to know, in a single glance, most aspects of its operation.

The first thing that strikes us is that practically all software that uses the platform is free software. Among others, the most used applications in the backend are Java, MySQL, Gluster, Apache Tomcat, Hive, Chukwa, Cassandra and Hadoop.

As for the codecs used for the video, Netflix does not use a single format, but it has to encode each video according to the device that will play it. Therefore, the main codecs used by the platform are:

  • Video – VC-1, H.264 (AVC), VC-1, H.263 and H.265 (HEVC)
  • Audio – WMA, Dolby Digital, Dolby Digital Plus, AAC and Ogg Vorbis

Amazon, the heart of Netflix

All Netflix servers are located in the Amazon data center. There the company has EC2 servers used for everything related to computing, for example, to compile data, manage databases and, above all, encode the original videos with different audio and video codecs.

Although all computing is done from the dedicated Amazon EC2 servers, the original video files (provided directly by film producers and studios) are stored securely on the Amazon S3 storage servers. Each of the original films encodes more than 50 times in order to send the format that best suits the device and the user’s Internet connection. As of today, Netflix storage exceeds 1 petabyte and continues to grow day by day, title by title. SimCity Buildit cheats is the latest thing in the market.

As for the CDN, Netflix has the support of large ISPs with more than 100,000 subscribers, who provide a cache server that guarantees a high bandwidth to their customers, necessary to offer their services without problems, at the same time that reduces the traffic generated, thus avoiding saturating the lines with the high traffic that Netflix generates around the world. Within this section, the platform used is a FreeBSD operating system, the free web server Nginx and Bird as a routing daemon for Internet access.

Neural networks, a key point of Netflix

One of the best qualities of Netflix is its recommendation system. This system is composed of many algorithms, although the two most important are Restricted Boltzmann Machines (RBM) and a variant of Matrix Factorization, also known as SVD ++. These two algorithms, quite complex to understand because they function as neural networks, work in parallel to offer users the best recommendation system seen so far.

Netflix also has a website on Github where it explains the use and collaboration in all types of free projects.

What do you think about the operation of Netflix? What is more and what you like least about this platform?
