The creation of design models as well as visualization of solutions is for some reason always a subject of great interest among all members of a productive team, be it a manager eager to master Sketch, or a developer who wants to make cool interfaces without the need to go to a designer. But we all know what happens when it comes to actually doing stuff.

My way

Hi, everybody!

My name is Anna and I work for an American company Scentbird NY as a product designer. Prior to that I was involved in developing flagship products in Alfa-Bank design team.

I was probably born under a lucky star but all my life I've been working with the developers who suggest the best product solutions, better than a lot of product managers and product owners. But anyway, my observation is that the earlier you involve developers into working on a particular task, the better off you are.

What you are about to read is actually a blueprint on how to conduct brainstorm sessions and generate not-so-obvious yet effective solutions, which are apparently really easy to reach and not that time-consuming.

[Update 15/09/2020: Molto2 is coming]

Our new product currently being finalized, the Token2 Molto-1, will expand on our technology by now supporting up to 10 Time based One-Time Password (TOTP) profiles. Earlier this year, with the miniOTP-2, miniOTP-3, and C301 we introduced the world’s first programmable TOTP tokens with time sync. The aim of these products was to provide a solution to the time drift that affects hardware tokens. We didn’t want to stop there, though! We also recognize the desire for multiple profiles which is why our latest product is a programmable multi-profile hardware token, called Token2 Molto-1. The clue is in the name, at least for anyone who understands Italian — “molto” is “many” in Italian. Having a multi-profile programmable hardware token means you can have only one device for up to 10 of your accounts.

Software development can be very tricky as it requires a lot of hard work and patience. The constant change of trends and technologies are pushing businesses and software development companies to adapt to these changes and ascertain their development accordingly. These sudden and quick alterations often slow down the development and impact of the planning and development of the software application.

However, to cater to these volatile demands, there are various frameworks available for software developers that helps them with the volatile market and user expectations. These software development frameworks are a big help and support to the developers as it quickens the development process and takes measure to cater to changes too. While we already know of the traditional waterfall model, others have been a constant partner in the software development process.

Video conferencing systems, so familiar to us today, have come a long way — more than a hundred years passed from fantastic ideas inspired by belief in unstoppable technical progress to the first mass implementation of video conferencing systems. A lot of dramatic events have come along the way. The way to success wasn’t easy at all.

Microgaming is justly considered a founding father of the online gambling industry as it created the world’s first online casino platform back in 1994. And the first mobile casino was launched in 2004, again by Microgaming. Over the years, the brand’s legendary casino products have gained a high-profile reputation.

For the past two years, there’s been a lot of buzzing about the Internet of Things (IoT). This has to lead to the rapid selection of connected devices over industries and is determined to pass the 11 billion mark by the end of the year. Major Companies including IoT software development as their major services.

All these “things” are now creating their things, namely, lots and lots of data. This data will be at the core of commercial and industrial digital transformation (which is essentially the underlying force behind the fourth industrial revolution).

In other words, life as we know it is about to change forever! How is it going to change? Let’s take a look.

1. AI (Artifical Intelligence) can Effectively Manage Oceans of information

We can’t talk about IoT without AI as the latter has the power to make IoT a whole lot smarter and more efficient.

In fact, consultants believe that AI is the brains behind IoT systems that may facilitate build them run power tool.

For example, as more and more connected devices start communicating with each other, enterprises will need to leverage deep learning, image recognition, natural language processes, and neural-network driven decisions to help them understand each other (and us humans) better.

So far, we can say that IoT has felt like an isolated experience where it was just about simple data. Going forward, businesses will strive to achieve highly integrated experiences by using AI to better understand their employees, customers, and the general public living in smart cities.

Surely you've heard the expression «bug hunting» many times. I dare to assume, you won't mind earning one or two hundred (or even thousand) dollars by finding a potential vulnerability in someone's program. In this article, I'll tell you about a trick that will help analyzing open source projects in order to find such vulnerabilities.

There’s a problem we needed to address in the course of developing our games. It’s complicated to generate a random number in a distributed network. Almost all blockchains have already faced this issue. Indeed, in networks where there is no trust between anyone, the creation of a random number solves a wide range of problems.

In this article, we explain how we solved this problem for our games. The first of these was Waves Xmas Tree.

Many programmers struggle when using formal methods to solve problems within their programs, as those methods, while effective, can be unreasonably complex. To understand why this happens, let’s use the model checking method to solve a relatively easy puzzle:

Conditions

You’re in a hallway with seven doors on one side leading to seven rooms. A cat is hiding in one of these rooms. Your task is to catch the cat. Opening a door takes one step. If you guess the correct door, you catch the cat. If you do not guess the correct door, the cat runs to the next room.

Managing your competition is an important skill that you need to have as a company. The management of competition can either be done by letting go of a market because it is too much to handle. You can also consider either selling yourself to a competition in a particular local market or acquiring them. Different companies adopted varied strategies according to the moment’s and the market’s demands.

Focus on Uber

Uber needs no introduction as a corporate or as a service provider. It has become synonymous with on-demand cab services and is slowly progressing towards providing many other services in the same fashion.

The phrase ‘Let's book an Uber’ has become common. In a decade, Uber has gained the status of a monopoly and has marked a prominent presence in more than 70 countries ever since its inception in 2009. However, it hasn't always been a bed of roses for Uber.

Uber has faced a lot of legal issues, some of them because of the legislature of the country, local drivers and passengers.

And our homeland's pushing us For reaching knowledge higher heights.

The available and interesting literature on science is a magic wand that helps the progress not to slow down and move forward. Thanks to interesting science literature, children begin to study voluntarily and with interest, while adults expand their horizons and do not allow the brain to relax. Biology, astronomy and mathematics supplant the saga about the elves and intergalactic ships. But while Western countries' nonfiction was always in smooth progress from Jules Verne to Eliezer S. Yudkowsky, then opposite it experienced both ups and downs in Russia.

Magento

Magento is an open-source PHP based platform for building e-commerce solutions. Built by the Magento company (now part of Adobe), it is used by over 350,000 developers all over the world. It enables the creation of highly customizable digital storefronts for Business-to-Customer and Business-to-Business purposes. Magento 2, the transformed version of the Magento E-commerce Platform, comes with brand new architecture, coding structure, and database design.

a) General overview

Magento’s platform is built upon PHP and MySQL. During its lifetime of 10 years (the version 1.0 released in March 2008 and the version 2.0 in November 2015, it has undergone changes in terms of structure and development patterns and is now in its second major version, Magento 2.

Magento’s structure is comprised of two main parts, one being the back-end, with the database and MySQL, and Model, Data and Service interfaces, as can be seen in figure 3. These are directly connected and used in Magento’s Blocks, Layouts, and Templates, which would be defined as the front-end of the application.

This is an English-language summary of two absolutely outstanding articles written by Vitaliy Malkin from «Informzashita» whose team, True0xA3, became the winners of the prestigious black hat competition The Standoff during Positive Hack Days 9 in May of 2019.

Vitaliy has published three detailed articles on Habr, two of which were dedicated to the description of the strategies that True0xA3 team used before and during the competition to secure this team the title of the winners. I felt that the only thing that those two articles were lacking was a summary in English so that a wider audience of readers could enjoy them. So, below is the summary of two articles by Vitaliy Malkin, together with images Vitaliy published to clarify his points. Vitaliy has OKed me doing the translation and publishing it.

There’s a lot of IoT SCADA solutions for factories and other manufacturing needs. Yet, there are cases (and quite a lot), when you need to develop your own SCADA system to cover specific needs of your project.

Original article — IoT dashboard library: visualize SCADA at a snap [Free IoT library]

We often use awesome Qt framework for implementing complex IoT solutions. For a bunch SCADA and SCADA-like projects, we came across the need for quick tool for developing device dashboards. That’s why we developed super lightweight unofficial Qt library. The library is open source, customizable, and free to use under MIT license. We also share a small set of developed widgets.

When mulling over the best programming language to use for data science, Python and R ring a bell (very quickly). While there are a lot of languages like C, C++, Java, Julia, Perl, and Scala, it's protected to state that Python and R are the harbingers in data science.

While a great deal of data researchers will discuss the customary shortcomings like data wrangling in R or data representation in Python, ongoing improvements like Altair for Python or R have adequately reacted to these shortcomings.

So which one would it be a good idea for you to decide for your next data investigation venture?

R has been ruling this space for a long time now. This bodes well as this programming language was explicitly intended for analysts.

Human pose estimation

A few months ago I came across one interesting open source project on the Internet — Openpose the aim of which is to estimate a human pose in real-time on a video stream. Due to my professional activities, I was interested to run it on the latest iOS device from Apple to check the performance and figure out if it is possible at all. It was also interesting to see how the performance of the neural network framework for iOS has been changed in the last years.

Whether you are a project management guru or just a beginner, you’ve definitely heard about Gantt charts. At first sight, these diagrams might seem chilling and complicated, however, they are not as mystifying as you may think.

Gantt Charts assist project managers and their teams to improve their productivity and efficiency of workflows and ensure timely tasks execution. The charts can be applied to small projects and the most complex ones. What are the secrets of the diagrams developed by Henry Gantt and what people in project management used before they were created?

Preface

What is ageing? We can define ageing as a process of accumulation of the damage which is just a side-effect of normal metabolism. While researchers still poorly understand how metabolic processes cause damage accumulation, and how accumulated damage causes pathology, the damage itself – the structural difference between old tissue and young tissue – is categorized and understood pretty well. By repairing damage and restoring the previous undamaged – young – state of an organism, we can really rejuvenate it! It sounds very promising, and so it is. And for some types of damage (for example, for senescent cells) it is already proved to work!

Today in our virtual studio, somewhere between cold, rainy Saint-Petersburg and warm, sunny Mountain View, we meet Aubrey de Grey, again! For those of you who are not familiar with him, here is a brief introduction.

Some time ago, the creator of Lua programming language, Roberto Ierusalimschy, visited our Moscow office. We asked him some questions that we prepared with the participation of Habr.com users also. And finally, we’d like to share full-text version of this interview.
