In this tutorial, we will learn how to select photos in a React Native application using the popular library react-native-image-picker. We will cover setting up a new React Native project, installing the library, getting permissions for the camera and library, and selecting and taking photos.

A BGP route leak is an unintentional propagation of BGP prefixes beyond the intended scope that could result in a redirection of traffic through an unintended path that may enable eavesdropping or traffic analysis, and may or may not result in an overload or complete drop (black hole) of the traffic. Route leaks can be accidental or malicious but most often arise from accidental misconfigurations.
From language translation and virtual assistants to self-driving cars and personalized recommendations, AI has been a buzzword for a while now, but it seems that it is only now with the new ChatGPT 3 being released to the public that it is so close to revolutionizing the educational technology field as well. In this article, I would like to give my first impressions, test results, and insights on the new technology.
ChatGPT is a chatbot by OpenAI that can write texts, code, answer questions, and solve various problems. It can even write college essays that, although lacking heart and personal touch, are still pretty good.
It somehow reminds me of the times when distance learning started captivating different fields and what started as a tool for kids with special needs (about 15 years ago, it was a major theme in pedagogical universities, at least) turned into massive online open courses from top universities available to anyone with access to the internet. In corporate learning culture, it went from "e-learning is a cheap and less effective replacement for offline trainings" to being a part of a complicated educational system where we can have the best qualities of offline and online learning for employees.
Right away, serious discussions emerged on the threats to the usage of ChatGPT. Since the beginning of December, many educators have been giving their opinion on its ability to write essays, code, and find correct answers for tests and on the studying culture that will probably need to change.
Hello there! Recently, I had very cool experience at my work. I needed to set tableView with a dynamic header. The information in the header was complete in the initial state, and when the user was scrolling the table, some part in the header was smoothly hiding and the main part remained on the top. Cool, right?
Once every true-linux engineer gets a trouble: there is no any software in his distro or it's built without needed options. I am keen on the phrase: "Only source control gives you freedom".
Of course, you can build this software on your computer without any src-packages, directly (with simplification: configure, make, make install). But it's a non-reproducible solution, also hard for distribution.
The better way is to make distro-aligned package that can be built if needed and that produces lightly distributed binary-packages. It's about debian-source packages(debian,ubuntu,etc), pkgbuild (for arch), ebuild for gentoo, src-rpm for red hat-based, and many others.
I will use cri-o like a specimen.
Before reading the text below I strongly recommend to get familiarized with the official Debian policy manual placed here and debhelper manpage.
Also you will be required to setup some variables like DEBMAIL and DEBFULLNAME for proper data in changelog and other places.

— Glitchy couch! — Anton exclaimed, yet another time crushing down his fingers by heavy coach he and Sergey were pulling for 14 storeys already.
— ‘Glitchy’? — Sergey asked — have you been coder in the past too?
They’ve been working almost a week together, but Sergey would have never suspected he was coder in the past. Lean and muscular Anton did not look the part at all.
— I had to in my student years, — Anton answered, abashed.
— Relax! One of us. Layout, three years and JS for every browser out there, — Sergey perked up, pushed the couch and pressed it a bit forcefully on Anton.
Global corporations became a part of our everyday life for a long time ago, their products often don’t leave an alternative option for users. Either is it exist? This article touches an issue of dominating big companies in certain areas, but also contains a row of useful tips. Spoiler of one of them: if you’re a user of Android then the tips will help you increase time between charging your phone and improve your privacy.
List of plugins that change the game. Great mix of famous and unknown plugins, that will make your life in 2023 easier.

We are the first year students studying Computer Science in Innopolis University and we would like to share our experience in developing a Verilog program to create the greatest Memory Game (MemGame) that has ever existed on the FPGA board.
In this article, we decided to create a game for extending human memory. You will read the background theory and the incredible story of creation.
The goal of paper is to demonstrate non-trivial approaches to give statistical estimate for forecast result. Idea comes from probability cone concept. A probability cone is an indicator that forecasts a statistical distribution from a set point in time into the future. This acticle provide alternative approaches using machine learning, regression analysis.
During the last years, one of the modern directions of technology development is computer vision. The main task of this direction is the classification of objects from a photo or video camera. In usual problems, it is solved using case-based machine learning methods. This work presents the application of computer vision for traffic sign recognition using machine learning algorithm. A road sign is a flat artificial object with a fixed appearance. There are two applied problems in which road sign recognition algorithms are used. The first task is to control an autonomous vehicle. Self-driving cars are cars that can drive on roads without a driver. A key component of an unmanned vehicle control system is object recognition. Objects of interest are primarily pedestrians, other vehicles, traffic lights and road signs.
Traffic signs are a fundamental portion of our day to day lives. They contain critical information that ensures the safety of all the people around us. A road sign is a flat artificial object with a fixed appearance. There are two applied problems in which road sign recognition algorithms are used. The first task is to control an autonomous vehicle. Self-driving cars are cars that can drive on roads without a driver. A key component of an unmanned vehicle control system is object recognition. Objects of interest are primarily pedestrians, other vehicles, traffic lights and road signs. The second task that uses traffic sign recognition is automatic mapping based on data from DVRs installed on cars. The task is relevant, because currently, compiling and maintaining detailed roadmaps requires either significant financial costs or a large amount of human time.
Let’s say you want to send an encrypted message to your friend in order to avoid it being intercepted and read by a third party. You generate a random secret key and encrypt the message with it. Let’s say you use AES. But how do you let your friend know the key to decrypt it?
In this article, we will explore how the Elliptic-Curve Diffie-Hellman algorithm works under the hood. The article includes the implementation of this algorithm from scratch, written in Python.
Games can give positive emotions and provide relaxation to a person. However, the main purpose of my project is to get a better understanding of the Verilog language. In addition, coding a game into FPGA will help to define the bounds of this programming language.
The following text consists of two logically connected parts. The first part constructively rules out the assumption that untraceability supposes anonymity. The second part enumerates specific practical tasks in the form of various scenarios when digital signatures (DS) do not provide correct solutions to the task. It is demonstrated that a complete solution can be obtained through a special combination of DS and an interactive anonymous identification protocol.
