There probably is no way one who stores some crucial data (and well, in particular, using SQL databases) can possibly dodge from thoughts of building some kind of safe cluster, distant guardian to protect consistency and availability at all times. Even if the main server with your precious database gets knocked out deadly - the show must go on, right? This basically means the database must still be available and data be up-to-date with the one on the failed server.

As you might have noticed, there are dozens of ways to go and Patroni is just one of them. There is plenty of articles providing a more or less detailed comparison of the options available, so I assume I'm free to skip the part of luring you into Patroni's side. Let's start off from the point where among others you are already leaning towards Patroni and are willing to try that out in a more or less real-case setup.

I am not a DevOps engineer originally so when the need for the high-availability cluster arose and I went on I would catch every single bump on the road. Hope this tutorial will help you out to get the job done with ease! If you don't want any more explanations, jump right in. Otherwise, you might want to read some more notes on the setup I went on with.

Do you think of taking the PMP exam? Awesome! Do you know how to plan your preparation for the test? Here I’m going to share the plan of how to get prepared for the PMP exam in 60 days.

PMP exam = your own project

To begin with, let’s clarify: you’re ready to work hard and to follow the plan. Otherwise, this journey will take you forever. The key here is to perceive the PMP exam as your personal project and manage it like you're managing projects for your clients. The difference here is that you are your client yourself; and you are the resource to release this project. What is more, you will need not only to plan this project, but to execute the plan yourself too. On one hand, it will add an additional challenge. On the other hand, it will make things even more exciting to get them done.

What do you need to launch this project? First of all, the input data. This is actually what you usually need to start a project. I’m talking about the key performance indicators that we consider while planning a project. They are time, scope and budget. Of course, funds are important. As you have decided to take the test and to pass the certification you should be aware of the process: how much the test costs, how much the course costs, and other relevant expenses. Therefore, let’s move directly to the time and scope.

Time

You have 60 days in order to get prepared for the PMP exam, and that is why you need to define how much time you are able to allocate to get prepared for the tests daily.

Yes, daily, because 60 days is quite an intense period. I know that for some people it takes six months or even a year to get prepared for this test. However, the less period of time you have, the more advantages you finally get.

Here is the thing, for the PMP there is no shortcut. It is quite a big volume of knowledge that you need to obtain in order to pass this test.

Headless e-commerce is a hot topic in the media and industry events. Business owners who learn more about headless eCommerce (usually called “headless commerce”) start feeling uncomfortable, not understanding whether it is sufficiently important to implement it or not. No one wants to stay behind with technology, but retailers do not have money left for unnecessary toys either. Let's have a look for possible benefits and pitfalls.

In this digital world, people prefer to work remotely. There are numerous tasks that each of us goes through every day. If I talk about an application's usage, then it has been predicted that there will be a 25% increase in global app downloads between 2018 and 2022. 

But it can be quite challenging for organizations to maintain and create multiple passwords. Hence, a password management software can be a great choice to manage this effectively. It is like your bank locker, where one can store numerous passwords. The users only need a master password to access the software.

Do You Know? 

The story of Fatal Fight started in 2015. The time when going global and having 5 million downloads on Google Play Store seemed to be a dream of every game developer.

In this article, I will talk about the way we converted the dream into our actual reality. To make it super understandable, find a guide below where I will cover all the stages of development of Fatal Fight and even more.

Research

The idea of Fatal Fight hasn't just come from nowhere. Before understanding what game to develop, we needed to research what are the current gaps in the mobile games market. And, to come to this point, we took several steps.

First, we analyzed what are the most searchable mobile games in the Google Play Store. It turned out, the top 3 mobile games that users were looking for were the following:

• Puzzle Games
• Car Games
• Fighting Games

Here we narrowed down our research. We were playing most downloaded games from each category to figure out if those games meet users’ needs while trying to answer what kind of challenges they have with those games.

As a result, Puzzle and Car Games had a wide range of mobile games with pretty nice UI/UX design and other characteristics. However, during the testing of the fighting games, the picture was quite different.

We were surprised by the fact that we could not find any proper games with satisfactory features. And I believe, not only we but also the dozens of users who were craving for favorable experience while playing a fighting game.

While asking ourselves the question “Why?” we found out that the main reason was the gameplay. The interaction between users and the games was complex. It was not comfortable to manage punching, kicking, jumping and other possible moves separately or even all at once on a smartphone.

Many of us grew up reading a classic, that was a staple of many home libraries. However, it doesn’t seem to be as prominent as it once was. To understand the ongoing shift in tech coverage, we need to explore its roots.

An eCommerce platform empowers startups, SMEs, and large enterprises to manage multiple online business processes such as website, marketing, sales, and operations.

The top eCommerce platforms handle online business tasks efficiently, and this finally helps enterprises in expanding their productivity.

We are proud to announce that we have built from ground up and released our high-quality (i.e. on par with premium Google models) speech-to-text Models for the following languages:

• English;
• German;
• Spanish;

You can find all of our models in our repository together with examples, quality and performance benchmarks. Also we invested some time into making our models as accessible as possible — you can try our examples as well as PyTorch, ONNX, TensorFlow checkpoints. You can also load our model via TorchHub.

Sales and operations go hand in hand if you wish success for your organization. Even a hint of compromise in any of the aspects could be the reason for the downfall for your business, which is a scenario that no one would welcome. Keeping such a situation at a distance is possible if you have a data-driven business strategy.

«Nothing makes you feel stupid quite like reading a scientific journal article» — writes the TV presenter and molecular biologist Adam Ruben. In a way, he's right — many of us get lost in the often confusing language of peer-reviewed papers. But the situation does not have to be hopeless. A bit of effort on the readers' part can go a long way. We looked at the techniques actual scientists use to navigate academic content. And compiled them into this two-part guide (Part 1: Getting Better at Understanding Academic Papers).

In his book «INSPIRED: How to Create Tech Products Customers Love,» Marty Cagan mentioned that successful teams put the following principles at the forefront when working with feature stories:

• Risks are analyzed in advance, not at the end.
• Products are defined and designed collaboratively, not sequentially.
• The team works on solving the problem, not on implementation.

The first two are more or less clear. Any well-educated manager knows that risks should be identified and assessed in the upfront. Besides that, many modern teams work or try to behave themselves on Agile's principles. But there are not so many companies in the world that follow the third principle.

Let us see what we can do.

Global Blockchain solutions spending is expected to surpass $15.9 billion in 2023. At the same time, this expenditure was $1.5 billion in 2018. Indeed, this is a huge influx in global spending, which depicts how companies will be investing more in blockchain solutions and blockchain-based mobile apps.

In this group, the major contribution will be seen from industries including finance, banking, healthcare, agriculture, and more. Amidst, outsourcing Blockchain development companies will also gain prominent attention.

If you are thinking about having Blockchain integration within your business solution, you must be having several questions in your mind, such as: what are the benefits of blockchain? Which are the best companies to hire? And more.

In modern business the need of automation in various processes have already become commonplace. It is already becoming difficult to imagine a warehouse or accounting without the use of specialized software. The representatives engaged in trade use a special application for registration and sending the order to office directly from pads or mobile phones. Mostly the orders that are ordered from the website are delivered in the form ready for processing. But at the same time customer relationships, at least in the medium and small business for some reason, very often maintain without the integration of automation and sufficient attention to the account.

Sometimes, tired of endless code review and debugging, you start wondering if there are ways to make your life easier. After some googling or merely by accident, you stumble upon the phrase, "static analysis". Let's find out what it is and how it can be used in your project.

If you use static analyzers, you will have, sooner or later, to address the task of making their integration into existing projects easier, where fixing all warnings on legacy code is unfeasible.

The purpose of this article is not to help with integration but rather to elaborate on the technicalities of the process: the exact implementations of warning suppression mechanisms and pros and cons of each approach.

It feels like Scrum has been around forever and everybody knows what it is and has interacted with it in one way or another.

Indeed, there were times when everything around scrum was innovative, valuable and efficient: from planning to sprints and so on.

However, recently the number of negative reviews has been escalating.

Why do you need a CRM system? Well, it’s at least more convenient than keeping your client database in Excel. Why do you need CRM with VoIP? If you have ever interacted offline, you know you cannot do it without telephony (orders, delivery, support etc.).

But what prevents 80% of companies from trying out a CRM tool? If prices is the matter, we are offering a free CRM system integrated with the phone system and free PBX.

To anticipate questions about installation difficulty, CRM setup and contact import doesn’t take more than 5 minutes.
