Paysend invites you to its first Paysend Connect meetup, which will take place on September 22 in Belgrade at Karbon space.

At our first meeting, we will talk about the company, the technology stack, the architecture solutions, and show a couple of demos.

Getting a task from a client, UX designers tend to pay attention to the design goals, not the contents of the website/app itself. There’s something completely wrong with it because the visual part might be superb, but when it frames a vague or wordy message, the client's goals won’t be reached.

To avoid this, a UX designer should dive deeper into the content, analyze it, and restructure it in an interface-friendly way. It doesn’t mean doing the copywriter’s job, it means collaborating. The reality is that sometimes the writing team is used to praising the product (because clients like that), or there is no copywriter involved in the project at all.

Provide proof instead of opinion

An impression is more powerful when the customer can conclude the product’s benefits on their own. Instead of a colorful line of adjectives like “ultimate” or “leading” you should aim at what exactly makes the product that cool. The trick is to be precise, preferably with an example.

In this article, we will look at a way to give the user the ability to upload any files, such as textures. And let's touch on the topic of launching JS functions from C# within Unity. As a result, we will get a script that, by calling just one function, will open a window for selecting files.

First mentions of micro service architecture application go back to the previous decade. Today this approach became the industry standard. Alexander Solyar, Lead software architect at Innotech, dives into details, shares professional insights and practical rules for working with micro services .

It feels like everything about LPs has already been said, however, I still keep seeing the same mistakes being made over and over again both by start-ups and established companies. Here are some tips, backed up by my 10-year experience as a UX/UI Director in agencies and product-led companies. These alone will give a nice increase in your conversion rate, I guarantee. 

Use a descriptive, not a salesy hero header 

Answer the questions “What?” and “For whom?” as early on the page as possible. A very common pattern is the largest copy being an inspirational abstract slogan and below it in smaller font the actual statement about what the product is and what it does. 

The present invention relates to an analog signal capturing devices generally and monochrome or color image capture sensors, such as a scanner or a Charge-Coupled-Device (“CCD”) for video and photo camera in particular, which are almost free from moiré and aliasing. The present invention relates to methods for enhancing the resolution of an image capture device and device for digital color/grey image displaying also.

Electronic payment systems have existed on the Internet for a long time, and some bugs in them are twenty years old. We've found critical vulnerabilities allowing us to steal money and drive up the balance. Today we will analyze typical implementations of payment processing and related security issues.

This tutorial will guide you step by step in building an Android chat app in Kotlin with the help of third-party messaging SDKs. The reason I chose Kotlin for this tutorial is that - it is a lightweight programming language suggested by Google for building apps that work on Android devices. 

In the steps ahead, I’ll show you how to develop an app in Android Studio, with messaging features that can integrate using SDKs. I use MirrorFly’s chat SDKs throughout this tutorial.

This technical note is devoted to covering information regarding all primary C++ programming language standards: C++03/98/11/14/17/20.

I am glad to share a technical note with some details regarding the C and all primary C++ programming language standards based on my experience and materials from the Reference Section of this document.

As of August 15, 2022, this technical note in PDF format consists of 72 pages.

Queries in PostgreSQL. Hashing

So far we have covered query execution stages, statistics, sequential and index scan, and have moved on to joins.

On average, online store users make 64 clicks before adding a product to the cart. Some clicks are useful - so-called discovery clicks that help lead to users finding a product they wish to buy, and some are useless that come as the result of poor UX. With great competition for convenience and increasingly reducing attention spans of users, each useless click reduces the number of visitors that will reach checkout.

Konstantin Kotelnik, an analyst at Innotech, ponders over making technical documentation easier to understand for developers and helping the clip-thought generation work effectively with large quantities of data. Read the article to find out about the potential emergence of a graphical IT-Esperanto and the standardisation of technical language.

Hi y'all, my name is Labertte and I use Arch btw.
Probably like every other Linux user, I'd like to buy a ThinkPad, put some lightweight distribution like Arch or Gentoo on it, and then go to Starbucks, get a soy latte and tell everyone that I use "linux". But I decided to go a little different route and give a chance to my old laptop that I was using about five or seven years ago.

You all know our mascot — a unicorn — many people grew fond of him! However, PVS-Studio has a supporting character who is also the antagonist of our product — a bug! Well, a bug is not omnipresent, indestructible evil. It's more like an everyday or a work-related trouble. In this article, you'll learn how we created a new character, and why he looks like a ladybug. Oh, and if you wonder why the hell he has a belly button — keep reading!

There are new challenges that force IT companies to look for non-trivial approaches to solve the problems of their customers every year.  And as you know LANIT-Integration is not an exception. Our team has already managed to work with many products, but we never stop discovering new ones.

In this article I would like to provide an overview of backup and recovery software from Chinese vendors and to compare these solutions with domestic ones.

FL_PyTorch: Optimization Research Simulator for Federated Learning is publicly available on GitHub.

FL_PyTorch is a suite of open-source software written in python that builds on top of one of the most popular research Deep Learning (DL) frameworks PyTorch. We built FL_PyTorch as a research simulator for FL to enable fast development, prototyping, and experimenting with new and existing FL optimization algorithms. Our system supports abstractions that provide researchers with sufficient flexibility to experiment with existing and novel approaches to advance the state-of-the-art. The work is in proceedings of the 2nd International Workshop on Distributed Machine Learning DistributedML 2021. The paper, presentation, and appendix are available in DistributedML’21 Proceedings (https://dl.acm.org/doi/abs/10.1145/3488659.3493775).

The project is distributed in open source form under Apache License Version 2.0. Code Repository: https://github.com/burlachenkok/flpytorch.

To become familiar with that tool, I recommend the following sequence of steps:

Once the Teacher asked the Author:

Are there methods of redundancy introducing at an informational level, other than those that are studied by the theory of error-correcting codes? Emphasizing that he is talking about information redundancy, the Teacher thus made it clear that the question does not imply various ways of energy redundancy introducing, which are well studied in communication theory. After all, the noise immunity of information transmission is traditionally assessed by means of a threshold value that is calculated as the ratio of signal energy to noise energy. It is known that the methods of the theory of error-correcting codes offer an alternative solution, allowing energy saving.

After a cogitative pause, the Author answered in the affirmative, following intuition rather than rational knowledge. Upon hearing the answer, the Teacher noticed that this is a wrong conclusion and there are no such methods.

However, over time, the Author began to suspect that the immutability of the paradigm formulated above could be questioned.

The reversal of Roe v. Wade, which launched a furious debate about abortion rights, has a side — and a very itchy side. In June 2022, the Supreme Court struck down federal protections for abortion rights in the United States, turning the decision on the legality of abortion over to the state level, many of whom had long been waiting for it: they had «trigger» laws banning abortion, and state prosecutors were preparing to prosecute for violating or trying to circumvent them.

Not even a week later, news emerged that the blow to women's rights might come from an unexpected (for naive Americans who are not familiar with the «Yarovaya Package» and other niceties of Russian legislation) side, when the willingness to «leak» personal data even without a decision was confirmed by the developers of major applications for women. Thus, suddenly, own gadgets and all the IT infrastructure that surrounds the modern man for his convenience, suddenly showed its downside: the possibility of total control over human life and actions.

Testing is one of the key processes in development. However, without analysis it is tough to say how effective testers really are. Innotech’s lead tester-engineer Pavel Petrov shared a number of metrics that are being used in project work.

Creating a product startup can be an exciting experience, but it can be a daunting one as well. On average, only 1 out of 10 startups is successful, according to the Global Startup Ecosystem Report. Therefore, to raise your prospects, there are quite a number of important considerations to make in advance. 

Bearing in mind everything you need when launching a startup is a challenging task, so it’d be a sound idea to rely on some well-established methodology. That's why we were inspired by the Systems Engineering methodology, presented in such industry standards as ISO 15288 and CFR21. In this article, we’ll make a brief overview of this methodology and highlight how it can help entrepreneurs to encompass and structure the process of creating and developing a startup.
