How AI can ease the work for UX Designers

Level of difficultyEasy

In the last couple years Artificial Intelligence has taken the world by storm, starting to revolutionize the tech industry in many aspects, including UX. AI can help UX designers to automate some routine tasks that take a lot of time, providing more space for creativity and product quality improvement. It’s not likely that AI might replace human designers in the near future, but it can definitely ease the work of designers in some ways. 

Let’s discuss how AI can be applied in UX Design these days:

The Yes Conditional/Positive Statement

Level of difficultyMedium

So let’s talk about the word yes.  Another way to say it is that, we need to give some positive statements to make a sale. 

I said, in the last article that Russians and Eastern European people are much more reserved with giving the answer of yes. So in this culture, it is normal to wait to have more facts about what the work will be for giving a positive answer. But this creates real problem and an absolute block when it comes to selling your IT software and project development to western cultures!

Let’s break this down into understandable pieces.

GSN vs Account Abstraction: Blockchain Superheroes in Search of Savings

Level of difficultyMedium
Reading time6 min
Views457

In the world of blockchain, where the word "gas" is most often associated not with gas stations, but with fees for transactions in Ethereum, the search for ways to minimize these costs is becoming increasingly relevant. Less heartache for an empty wallet and more time to solve really important issues... for example, what to cook for lunch =)

Similar to the epic Batman vs Superman battle, compare GSN and Account Abstraction. As in any superhero story, each of them has its own unique abilities and disadvantages, which we will look at in detail.

GSN and dApps: A Novel without gas obstacles

Level of difficultyMedium
Reading time8 min
Views386

Imagine: you've just created an incredible decentralized application, and it's so cool that even your grandmother wanted to try it. But once users are faced with the need to pay a commission, the entire UX (User Experience) rapidly slides down like a ball down a slide. Blockchain promises a bright future in which decentralization, transparency and security are our best friends, and it makes us pay for daily operations. Imagine if you had to pay every time you like on social networks or send a message in a messenger. It's terrible, isn't it? But dApps users face something like this every day.

But now, like a prince on a white horse, GSN (Gas Station Network) appears. With its help, developers can make their applications gas-less, and users will finally be able to forget about commissions like a nightmare.

In this article, we will look at what GSN is, how it works, and how to implement it into your projects to please users.

Cloud Communications: Understanding UCaaS, CCaaS, and CPaaS

Level of difficultyEasy
Reading time4 min
Views1K

In today's world, where businesses increasingly rely on effective communication, cloud technologies offer a wide range of solutions to optimize interactions both within the company and with customers. Three of the most popular options are UCaaS, CCaaS, and CPaaS. While they all fall under the umbrella of cloud communications, their functionality and applications differ significantly. Let's delve into the details.

UCaaS (Unified Communications as a Service)

UCaaS unifies various communication channels, such as voice calls, video conferencing, messaging, and email, into a single platform. This allows employees to easily communicate and collaborate with each other, regardless of their location.

Benefits of UCaaS:

Вышел Python 3.13. Что в этом для не знакомых с Python?

Куй железо не отходя от кассы

Иными словами, Вы тут же захотите его попробовать - самое время, это стало (много) приятнее чем когда-либо.

Что делать и кто виноват

Виноват, очевидно, Гугол - запоздал с увольнениями в команде Python. А делать придётся компиляцию из сорцов - даже в AUR сейчас RC1. Как - на примере Arch в форме EndeavourOS.

Python часть системы, но он 12, поэтому 13 нужно держать отдельно. Скачав с python.org и распаковав

./configure --enable-optimizations --with-lto --enable-experimental-jit=yes --prefix=/home/andy/.python
make

Конечно, чего-то да не хватит, но об этом будет чётко сказано, поэтому и например

yay clang
yay llvm
make

Будет чётко сказано чего не получилось, за 12 такого не помню, у меня - без tkinter. Ну и ладненько. Поскольку make test придумали трусы,

make install
~/.python/bin/python3 -m venv Python13Env
cd Python13Env
python

И наслаждаемся новыми фишками - редактируем процедуры и выходим легко, как по мне - самое очевидное. И да, на первом же (дурацком) тесте - на 10% быстрее.

XML parsing into plain Map in Golang

Level of difficultyEasy
Reading time4 min
Views1.6K

While in 2024 using XML looks a bit outdated, it still happens. And sometimes it happens we are to deal with XML having "free-structure", i.e. it couldn't be parsed into tree of user-defined structs. For JSON there still is a way to parse it with a single call into map[string]any and work with it using careful type assertions. Regretfully, there is no similar feature for XML (in Golang). Here I'll draft suitable function and demonstrate it - both for others and for myself if I ever need this again (recreating it from scratch may be somewhat painful).

How to bypass CAPTCHA: Breaking Down a Complex Process in the Simplest Terms

Level of difficultyEasy
Reading time7 min
Views1.7K

CAPTCHA is not just a single word that can be defined; it's an acronym consisting of nine words (and two prepositions): Completely Automated Public Turing Test To Tell Computers and Humans Apart. This mouthful was shortened to the concise CAPTCHA to avoid creating yet another hard-to-pronounce term. Translated into Russian, this abbreviation sounds like "Полностью автоматизированный публичный тест Тьюринга для различения компьютеров и людей" (Fully Automated Public Turing Test to Differentiate Computers and Humans).

Modern X-ray detectors

Level of difficultyMedium
Reading time11 min
Views2K

Wilhelm Röntgen discovered X-ray November 8th 1895, when he did experiments with cathode rays in a vacuum tube. To capture and save images of the shadows from the X-rays, he used ordinary photoplates. Fortunately, sensitive to visible light silver based photoemulsions turned out to be sensitive to the X-ray too. These photoplates became the first X-ray detectors.

More than 100 years of scientific progress led to the creation of a number of various detectors for recording X-ray images. Developments of the microelectronics and semiconductor manufacturing technologies are crucial for development of the modern X-ray detectors. These detectors can transform the energy of the X-ray photon directly to the electrical signal. They allow capturing detailed, digital, high-resolution X-ray images.

Digital images are easy to work with. For example one can merge multiple macro images into an image of the whole object and represent monochrome images in false colors like Simon Procz did with this X-ray image of a flower he did in 2012.

React Native Splash Screen — support for different themes

Reading time5 min
Views1.4K

Hi all! The dev.family team is in touch. In this article, we are sharing a short guide on how to install Splash Screen in a cross-platform app written in React Native with support for multiple themes.

Splash screen is the first screen that users see before loading into the main application. This screen is perhaps the best way to make the name of your app, and in general, its entire name, more memorable.

But this is not the main role of the splash screen. Under it, for example, you can hide receiving data from the API and loading the main application. We do this when we show the loader on the screen when loading the same data. This allows you to improve the UX and immediately demonstrate the finished application to the user. And as a result, remove the extra loader when opening it for the first time.

In this short guide, we will look at installing splash screens for iOS and Android using the react-native framework using the react-native-splash-screen library.
