How the Internet of Things is changing mobile development. What's new in mobile development in connection with the development of the "Internet of things"

We all know about options with a “free cash desk!”, distribution of leaflets near the metro, a meeting with an important view right at the department of our own university, and many, many others. All these formats of work, of course, have been actively used by students as additional income for many years.

But we decided to find out what professions the 21st century gave us, the century computer technology and life online. Almost all new and modern part-time jobs are remote work. In other words - a very convenient freelancing, which practically does not distract from study.

1. Work with the word

Finding such a vacancy is easy: either on specialized sites, or directly in specific editorial offices. The second way is more efficient. In the letter, write that you are well acquainted with the publication, what you would like to do, indicate several possible topics for future articles. The texts themselves do not need to be written in advance, it is better to think about what they can be about and make an annotation.

2. Programmer

A programmer is a specialist who develops software (software) for personal, embedded, industrial and other types of computers, that is, programming. It can be either the manager of large software development projects or a single student writing the code for a specific program.

Almost every month new versions of programs are released, equipment characteristics are updated. It turns out that specialists in the field of information technology should always be aware of these changes. Therefore, the ability to self-learn is one of the main skills that a programmer should have.

This profession is in demand at all times. In addition to the usual job search sites for a programmer, there are also specialized ones, such as: Jobit.ru, IT-rabota.ru, 1clancer.ru. Therefore, if you understand the programming language, enjoy!

3. Posting

In fact, posting is giving life to sites. The content of the resource with small messages-posts of about 150-200 characters.

Everyone can write posts, because it is much easier than copywriting or rewriting. The forum involves live communication, so there are vernacular, slang and the like on the sites. All these techniques are used to be closer to the interlocutors, but there is one condition - the poster must be literate.

All messages are written concisely and understandably for everyone. And within the framework of the rules of the resource (the use of obscene words, insults, and so on are prohibited). Posts should be informative and unique. They are checked with the help of special programs.

Also in posting it is forbidden to copy or write off information. And when creating a topic, a loud title is created that will reflect the essence.

4. SMM-manager

This relatively new profession is rapidly gaining popularity. There are not so many people who skillfully handle social networks. If more than a thousand people subscribe to your blog on Instagram, this does not mean at all that you understand the management and promotion of social networks. You still have to master certain skills.

Your main tasks will include increasing the reach of the audience that is interested in the product or service of the client, and strengthening the image of a particular brand. You will also have to decide for yourself which in social networks the brand will be promoted, how, how the work will be built to find and neutralize the negative, how the work will be carried out to increase the audience, and much more. In short, it is difficult, but interesting.

5. Selling something interesting on Instagram

If you have not only the makings of a cool SMM manager, but also resources for sale, then go straight to Instagram. Everything is sold here: from earrings handmade to hairdressing. The most popular is, of course, the sale of clothing and accessories. If you are a needlewoman, sell your author's things. The principle of "buy low - sell high" has not yet been canceled.

As for selling your own services, it is difficult to imagine a more convenient and effective method. You post a photo of your work, a potential buyer immediately sees not only an excellent service, but also rave reviews, respectively, the degree of trust in the content goes off scale. Stylists, makeup artists, photographers, personal chefs, bakers, trainers, consultants - they all actively use the power of social networks.

In August 2016, Gartners published the Gartners Hype Cycle 2016 study, which shows the cycle of technology maturity and shows which are at the peak of attention, which will be in demand in the near future, and which are gradually disappearing from view.

The Internet of Things and various smart hardware technologies have been at the peak of popularity for the second year. But what is it? How can we use this in Everyday life? And what can we expect in the future?

Halfway to the finish line

The concept appeared in 1999 as part of an MIT project for Procter & Gamble. They implemented RFID tags to improve their supply chain management system. As Wikipedia says, “IoT is the concept of a network of physical objects that interact with each other without human assistance. They exchange data, analyze statistics, sometimes even make their own decisions.”


Back in 2008-2009. The number of connected devices has exceeded the population of the Earth. We can say that we already live in a connected world, just so far it is not very noticeable. McKinsey University predicts that by 2025 the IoT will contribute between $3.9 trillion and $11.1 trillion to the global economy. For comparison, the global level is about 80 trillion. significant share.

Analysts draw such exponential growth in the number of connected devices. We are now in the middle of this curve.

The concept has penetrated into all spheres of life: systems for managing road traffic, connected cars, power grids, devices for analyzing medical indicators, household appliances, user trackers. Even outdoor advertising is already becoming “smart” and allows you to personalize the message on billboards.

In many areas, the application of the Internet of things is already very successful and cost-effective.

Mobile applications and "smart things" - our company for the near future

The central interface for human interaction with “smart systems has become mobile applications. This can be seen in the example of custom products. For example, a "smart" toothbrush. Where else, if not on the phone, will we look at data on the quality of brushing our own teeth? You can brew coffee without getting up from the sofa in a smart coffee maker or see what's left in our smart fridge right from the store. But the concept does not only penetrate the b2c segment.


Many gas pipeline networks are already hung with control sensors, and it is not enough for engineers to have a single central control point - they need to be equipped with mobile applications. So they can get up-to-date data and interact with the system “in the fields”.

Even seemingly conservative companies like Russian Railways install sensors on track sections to analyze the load on the rails. And there is an application to work with all this.

What can you do with a mobile IoT app?

  1. Observe (readings of instruments, sensors, video).
  2. Analyze (build graphs and reports).
  3. Manage (open / close, turn on / off, trigger an alarm, send messages and perform many other actions).

As an example of applications, we will give several projects that we developed for different companies.

  • There is a hypothesis that the quality of driving is related to the number of accidents. And this, in turn, affects the cost of insurance. Therefore, it is proposed to build a special device into the car that collects data from the CAN bus. This data is transmitted to the server, where the user is scored: how well he drives the car (how he slows down, accelerates, exceeds the speed limit). The application allows the user to analyze their driving style and adjust it to get a good discount.
  • Security systems are also becoming smart, cloud-based and mobile. We worked with the Sea-Nord company, which serves hundreds of facilities in different cities. There is no web interface here. But with mobile phone you can arm and disarm objects, take readings with a temperature, fire, gas, leak sensor. And all this allows you to make a mobile application.
  • There is another interesting type of application - those that act as a server. That is, they are a full-fledged routing and data processing center, they independently implement business logic. For example, a cafe automation system operating on the counter service model with service at the checkout. At first glance, this looks simple.

The system consists of dozens of devices that are connected to a local network and controlled using the iPad. The network works autonomously without access to the Internet, but, if there is a network, it is synchronized with the "cloud". Some iPads are at the checkout, some are in the kitchen and at the bar, others are at the waiters. Checkout gadgets are responsible for routing orders between devices and getting back execution statistics. They interact with peripheral devices: printers, fiscal registrars, cash drawer, card reader. Even reporting to the tax office is sent online through a specially connected fiscal registrar.

What are the subtleties of the development of "smart" systems?

Scary picture? But you have to maintain this system in order to understand which devices to connect to what and manage access rights in conditions where you cannot rely on remembering a password by a specific user (for example, a password from a medical device by a nurse).

Another nuance is the problem with energy efficiency. This year we worked with the St. Petersburg bicycle rental system Velogorod. The idea is that you don't need to use a terminal to rent. A person comes with a mobile application, presses a button and takes a bike. I want everything to happen quickly. But the problem is that the stations are not connected to the city's power grid. They are powered by the sun. And there is little sun in St. Petersburg. A charge is rarely enough for a whole day.

In the development of such systems, it is necessary to optimize the interaction of applications with hardware and think over the cunning schedule of their modems, day and night modes. And user requests should not be sent in real time, but every few seconds (depending on the time of day). This method is more energy efficient, but not easy to develop. Numerous tests have ensured the stability of the system: delays are not significant for users and stations do not run out of power.

What's new in mobile development in connection with the development of the "Internet of Things"?

An interesting trend has been the integration of machine learning algorithms into mobile applications. They allow you to classify data based on neural networks in order to form various action scenarios.


We are developing now. It is a sheet of sensors. A person lies down on it and after 10 seconds the doctor receives a cardiogram. In this case, he can lie on his side, back or stomach. It depends on how he lies down, which sensors we will take readings from, and we are required to use real-time machine learning to recognize how a person lay down and moves, constantly choosing the right signal for building an ECG signal.


Among the total number of heart attacks, a fairly large percentage happens at night, when no one expects it. Using such a system, you can analyze a continuous stream of data directly on your mobile device and see critical changes in cardiac activity an hour or two before a heart attack. During this time, you can have time to call an ambulance and save a person.

What awaits us in the future?

  • Lots of cool gadgets in the b2c segment. We'll see how "smart" everything becomes: toothbrushes, combs, devices for animals - the imagination is endless. The development of IoT devices is getting cheaper every year. With ready-made boards today, any enthusiast can create their own "smart" systems and connect them to the network.
  • Hundreds of platforms for storing and working with IoT data. They already exist, but there are more and more of them.
  • Startups "on the knee" and products of corporations of the level, SAP and. Funds have been created to support startups in this area and new companies are constantly appearing.
  • Big data and machine learning. Working with big data and machine learning will become increasingly relevant. In the future, we are waiting for "huge data".

"Smart" systems have an impact on all spheres of life and sectors of the economy. And everywhere they become a link mobile devices. Will it always be like this? It is hard to say. But creating mobile applications is becoming more and more interesting.

What is the danger of being a musician? Every day he faces such moments as stress, lack of sleep, a busy schedule and being in constant noise. The sudden death of a talented musician has always been widely reported by the press and mourned by fans. The reasons for the death of creative people were both accidents and their way of life, which goes beyond what is permitted.

We can say that thanks to Eazy-E, in musical environment a new genre emerged - gangster rap. Eazy-E was drug related. With the money received from the sale of a large batch of heroin, he helped the group N.W.A. climb the musical Olympus. The influence of the musician on the revolutionary ideals of black people is very significant.

At a time when the name Eazy-E was on everyone's lips, he fell ill and ended up in the hospital. This happened in 1995. It was rumored that the musician entered the medical center with asthma. In fact, he was diagnosed with AIDS, from which he subsequently died.

Aaliyah died in a plane crash

This girl was known in musical circles as an R&B singer. When she was 5 years old, she moved with her family to Detroit and started dancing there. At the age of 14, Aaliya was able to release her first album, which was produced by R. Kelly.

With her help, he learned to overcome physical problems and became less shy. Within six years, Williams was able to record 66 songs, 37 of which became hits.

But success "broke" Hank. The stress of touring exacerbated his back problems. In an attempt to relieve emotional stress, the musician became addicted to alcohol. And then everything went downhill. Williams started skipping shows. In 1952, he went to the doctor, who, at the request of the musician, prescribed dangerous prescription drugs for him. In December of that year, Hank died on his way to a show organized in honor of the New Year holidays.

Selena Quintanilla-Perez was killed by a fan

She was a singer, actress, model, designer. Selena Quintanilla-Perez was considered a significant figure among Latin American musicians. In 1989 it was released debut album. And songs from the second collection were at the top of the music charts for eight months in a row. During this time, Selena was a well-known activist.

In 1995, the singer released her new album on the English language. In the same year, 23-year-old Selena was shot dead. The murderer turned out to be Yolanda Saldivar, the head of the fan club, who was fired for embezzling the general funds.

Within two years of her death, The New York Times compared her to Marilyn Monroe and Elvis. Selena's influence on contemporary fashion and pop music is still felt today.

Otis Redding's revolution ended too soon

This man was not just a successful musician and artist, but also a revolutionary. Born in Georgia in 1941, he grew up among "whites". Even in the 60s, a black artist used his physical data and sexuality when performing on stage. Often his manners were copied by colleagues in the shop. He toured America, Great Britain, France, Scandinavia, recording more and more hit works. All glory ended in one moment when Otis got into a car accident. The tragedy occurred in 1967 in Wisconsin. Five teenagers - members of the Bar-Kase group, which supported the musician on the tour, also died. At the time of his death, Redding was 26 years old.

The murder of Sam Cooke

This is a musician who has overcome the barrier that separates the white and black audience. Sam became one of the first black artists to find a record label and became a major figure in the civil rights movement.

Sam Cooke's career began in the 1930s when he sang in his father's church choir. Already by the 50s, he was able to release the most successful hits of the decade. The musical direction in which Sam worked combined R&B, gospel and pop genres, which was unique for the era in which he lived.

The musician achieved his popularity with a show at the Harlem Square Club (Miami). In 1964, Sam Cooke was killed in a confrontation with a hotel manager who claimed he wanted to attack her. The circumstances of the musician's death were subsequently questioned. It still remains a mystery what happened on that ill-fated night.

Duane Allman died under the wheels of a motorcycle

The name of this musician has become the most famous in the world of rock and blues. He started his career with his brothers in 1961. The Allman Brothers Band, whose lead singer was Dwayne, became the most influential rock band in the 1970s. The musicians achieved significant success after the release of the album At Fillmore East.

In 1971, the rock band took a vacation. Dwayne celebrated the birthday of the bassist's wife, Berry Oakley. On that day, he returned home on a motorcycle. On the way there was an accident - a truck collided with a biker. Dwayne was under the wheels of a motorcycle. He died in the hospital 3 hours after the operation.

Marc Bolan died in a car accident

He started his musical career inspired by Lonnie Donegan. In the late 60s, he formed his own group T.Rex and by the beginning of the next decade began to improve the psychedelic sound that made him so popular. In the mid-70s, Bolan was one of the most famous glam rockers. He released more than half a dozen hits, and gave concerts throughout the country.

For some time, Bolan suffered from drug addiction. But by 1977, the musician was able to cope with addiction. He appeared before the public in great shape in the evening television show on ITV.

1977 was also a fatal year for the musician. His climbing career was cut short sudden death Bolana in a car accident.

Currently, fashion is so multifaceted that trends from the 70s, 80s and 90s can easily coexist in it. From year to year, designers bring forgotten things back into fashion, present them in a new light, and they resonate with customers.

Turtleneck- the basic element of clothing that was cult thing. In the 70s, they were worn with skirts, trousers, sundresses, jumpers, and also worn under shirts and dresses. This year, the trend is back, and the turtleneck is also worn with almost everything - the layering trend in full glory.

Trousers-pipes and bell-bottoms- very popular clothes of that time, nowadays they are also at the peak of popularity, and are presented in the collections of many designers. Pants wide from the hip will help hide figure flaws, suitable for owners of any physique.

Suits with both skirt and trousers in the 1970s were the staple in every fashionista's wardrobe. The color palette and designs at that time were varied, however, as they are now: tweed, leather, suede, check, bright colors. Now suits are also rapidly returning to fashion and, it seems, for a long time.

Geometry. In the early 70s, the influence of the 60s was still felt, and everyone wore a vertical stripe and a square. This season, many designers have built a cult of a check in all sizes and colors, to which mass-market stores and fashionistas around the world quickly reacted.

Neckerchiefs- an important final part of the image of the fashionista of the 70s, they look graceful and elegant. Now neckerchiefs are so popular among fashionistas that they are worn not only around the neck, but also on the wrist, bag, and even decorate their hair. This trend is gaining momentum, neckerchiefs are made by almost all famous fashion houses.

And after the young performer recorded his no less good clip to Timati's song "Don't Go Crazy" Then he was noticed in the production center " Black Star Inc." And already in 2015, his song "The Most-Most" becomes best song of the year at the RU.TV award. Now Yegor Creed is the youngest sought-after artist of the Timati production center.

7. Elena Temnikova


Russian singer Elena Temnikova began to seriously engage in music at the age of 10. Then the girl actively participated in regional music competitions and won first places. As a result, in 2002, Temnikova was sent to a competition in Moscow, where she took the Grand Prix. After that, she took part in the Star Factory project, where she met producer Maxim Fadeev.

In 2006, Fadeev created the Silver group, where he invited Temnikova as a soloist. And already in 2007, the female trio went to Eurovision, where he got third place. Then the songs of the Silver group became hits and were played on all radio stations and TV channels.

In 2009, there were rumors about the departure of Elena Temnikova, but they did not come true: the singer performed as part of the group for another five years. Truly Temnikova left the group in 2014, according to official version, for health. But the singer managed to stay afloat: Temnikova began her solo career and released her debut mini-album this year.

8. Anna Pletneva


Sexy musical performer Anna Pletneva dreamed of becoming a singer since childhood. Anna began to take her first steps in show business in 1997, when the girl took a place in the very popular Lyceum women's group at that time. Pletneva stayed there for eight years, and then went into a solo career.
