How to work with itFocus on content and be attentive to your audience.

The sooner you abandon ineffective tools, the sooner you'll get the results you want.

Once you fall into Instagram's disfavor because of a complaint about a single post, the profile is permanently off your subscribers' radar.

Adam Mosseri talks about it as a kind of abstract concept.

At the same time, restrictions imposed on a single post do not affect the account as a whole, unless you systematically violate the rules and knowingly publish false information.

How to deal with itFirst and foremost, it's worth accepting that most subscribers don't see what you share because they view less than half of your feed.

Some of these shortcomings can be eliminated in the near or distant future, with the rest, apparently, will have to be reconciled.

For some studies, these limitations are critical; in others, they can be neglected.The main  disadvantages and limitations of sociological research  via the Internet include the following:Sample offsets1)  Lack of representativeness... One of the most serious problems of Internet research is that the sample made up of users of the World Wide Web is not representative of the general population - the inhabitants of the region under study as a whole.

More or less free access to the Internet is now available only to about 10% of the country's population.

Obviously, the results obtained on the basis of a survey of these citizens will differ markedly from the opinions of the rest, therefore the magnitude of the systematic measurement error is extremely high here.Thus, the political preferences of the Internet audience are fundamentally different from the preferences of the population as a whole, so there is a high probability that the opinion of Internet users on other important issues will not coincide with the opinion of all Russian citizens.2) The  spontaneity of the sample.

Thus, the most commonly used sampling method is the “self-selection method”.

Nevertheless, it should be noted that at present, even in face-to-face polls, the number of refusals to participate in interviews has increased so much that it accounts for more than half of all requests from the interviewer.

If it were easy to win from bookmakers, they long ago ceased to exist due to the lack of profit, but betting is flourishing and the number of BKs is growing, which indicates not only the interest of users in this type of entertainment, but also the commercial perspective of this business.It is difficult to compete with the bookmaker on equal terms, but it is possible, and there are some tips to increase your chances of winning:Take it easy when you lose.

Record all bets made in a separate file or on paper, so that you can study them later and identify successful and unsuccessful deals.The main attention should be paid to winning disciplines, championships and types of bets, for example, after the analysis you can find out that almost all totals give profit, but predictions on the main outcome bring losses.Choose your bookmaker carefully.

Take the time to understand the rules and features of the chosen sport, otherwise you will not be able to accurately predict the results of matches.

In addition, you need to study at least the basic types of bets - singles, systems and expresses.Act on the basis of calculations, not intuition, and avoid betting on your favorite teams.

Be careful with sports betting forecasts published in social networks, messengers and forums.Much of the information on the Internet is irrelevant, not confirmed by any calculations, and in general, instead of listening to someone else's opinion, it is better to master the skills of statistical analysis and choose the best bets yourself.

Learn to control your emotions, so you won't take unnecessary risks and try to win back a big loss.Activate promotions and bonuses only after you carefully study their conditions.

Scaling the Application BackendBackend is the backend area of applications, where business logic is handled and where user actions and events are handled in response to them.Scaling the backendThe backend is responsible for everything that happens on the server side of the application.

For example, one server handles the posts and comments of a website; another server handles the statistical data and advertising banners.

This approach is used for the simplest scaling bacend.In the case of horizontal scaling, we add a few more servers to the existing one.

That is, as already mentioned, to divide it into separate components, a piece of each of which will be responsible for processing a certain action.There's no need to spread the actions over the whole backend.

For example, to get some data, let's say ordinary posts on the site, a user makes a request to the page.

At this point, the frontend connects - a script that processes all requests and launches the core of our application.

For example, kabbadi, netball, rowing, cycling, and the like.

Bookmaker analysts superficially study events in such disciplines and adjust the odds with a delay, resulting in a lot of value.

For popular and prestigious soccer leagues, bookmakers offer the highest odds, as well as an extensive roster, high limits, good live conditions, and special promotions.

In addition, it is very easy to find information to analyze, everything is disassembled in detail in thousands of sites.High motivation of opponents.

It is wise to skip games where there is a lot of uncertainty.

Let's take soccer as an example, but the same technique can be used for other sports as well.Gather information about the matchThe first step is to find as much information as possible about the upcoming soccer game.

Players have dozens of betting options at their disposal, their types depend directly on the sports discipline.

For example, by choosing cybersport, it is possible to predict how many opponents the team or athlete will manage to kill, in what time the round will be completed, whether it will be possible to kill the main villain, to complete the mission, etc.In traditional sports, the most common are the following types of bets:Single - allows you to determine the outcome of a single event: victory of the first or second team or a draw.

The calculation of winnings is made by multiplying the odds and the amount bet.

When making a bet, you can specify the total more or less than a certain number (2.5, 3.5, etc.)

BK has a team of analysts who carefully study each match and set the odds in such a way that they always stay in the black.

On the other hand, there are all chances to win in the long run, and mathematics will help.

Now people are increasingly sitting at the computer in online casinos, trying to hit the jackpot.

In the casino, everyone can launch a slot, roulette or play cards for money.

Everything is simple and clear, such entertainment is comfortable, interesting and winning.

At the same time, they smoothly move to the Internet.

In particular, in Egyptian tombs, archaeologists have found images of animals throwing bones.

The deck had 96 cards.

An effective strategy, constant monitoring of indicators, a bookmaker with favorable conditions of the game, luck - all this will be useless for a bettor who has no idea about the psychology of sports betting.

It is the stability of the psyche and the right mindset that is the key to winning, and you need to control yourself constantly, otherwise there is a risk of losing all the money in the account.

If it is only about having a good time and releasing adrenaline to relieve stress and get new impressions, then you can not fill your head with unnecessary information and just trust your intuition.It is very likely that one or two times you are really lucky, but then you will still lose money, not guessing the outcome of the event.If you are aiming to make a profit with the help of successful bets, you need to be ready to work on yourself, because every action affects the final result, so you should not be emotional and bet at random.Becoming a true professional is not easy, but it is possible if you perceive the process of betting as a job that requires a responsible approach, attentiveness, focus on the final goal and constant improvement of abilities.

In this case, the basic skills of self-control and discipline that allow you to:process large amounts of statistical information; analyze odds and other indicators;select a productive strategy for the game;evenly allocate time and available financial resources; track transactions and bets made to weed out unprofitable deals;evaluate expert predictions and make your own assumptions of how a particular match will end, based on the study of the characteristics of opponents and their past games;see the real situation, without embellishing anything;determine the most promisingOnly he who gambles never loses, and the bettor's task is to make sure that the number and amount of successful trades is greater than the amount of unsuccessful ones.It is definitely not worth even starting to gamble for people who:think that they can win solely thanks to their own luck;are not stress-resistant and can hardly tolerate defeats; are not able to take risks and make quick decisions;are inclined to trust other people's recommendations instead of understanding the matter and making a conclusion themselves;were previously addicted to gambling; are not ready to allocate time and effort to work with statistics;are not able and do not want to count money;are panically afraid of losing;do not recognize their own weaknesses;are not able to control their own actions when finding Mistakes not to make when betting on sportsThe most common psychological mistakes beginner bettors make are:Striving by all means to win back after a series of losses.

Orientation to deals, where it is possible to snatch a large sum at once, but to do it, it is necessary to risk the entire deposit.

Finally, let us give you a few recommendations from brokers with many years of experience:Avoid inflated expectations.

Some respondents may take part in the study several times, having a significant impact on the final distribution of answers.

The likelihood of this increases if there is material reward for participating in the study, or the survey participant is interested in distorting its results.

Accordingly, it is necessary to identify the respondent, which prohibits the possibility of multiple responses to the questionnaire from the same computer.To avoid repeated participation in the survey by the same people, identification of the IP-address of the computer from which the respondent logs in (in this case, however, respondents who can log in from the same IP-address “drop out” from the sample).

Identification and control is carried out using special cookies.Also, in addition to identifying the IP address, access to the electronic questionnaire is often organized using unique codes, passwords, etc.

Although these measures are not always 100% effective (if you want to take the survey again, you can do it with computer or re-register under a different name and using a different password), however, they reduce the likelihood of re-participation in the study.Lack of data on the general population.

The probability of deliberate distortion of information is high.
