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? Read more

  • Модераторы Хабра в лицах: будем знакомы
    HabrHabr
    Я никогда не мечтала быть модератором. Ну то есть, даже мысли не было: хочу или не хочу, в Хабре я занималась совершенно другими вещами. Однако жизнь любит шутить, и 12 июля 2017 года я стала ведущим менеджером по работе с пользователями. Эта должность предполагает кучу функциональных обязанностей, но для пользователей Хабра я именно модератор. Мне казалось, что я неплохо знаю коллег, но изнутри команда оказалась необычной и удивительной, настоящей dream team со своим духом и стилем работы. Мы, модераторы, небольшая команда отдела по борьбе работе с пользователями. Иногда нас спрашивают, а не роботы ли мы. Иногда обижают, иногда сердечно благодарят. С некоторыми пользователями мы дружим, с некоторыми — не очень. Как правило, всё взаимно, всё как у людей. Мы уже рассказывали о том, как работает модерация — подробно, со смешными примерами и ответами на вопросы. Сегодня мы хотим познакомиться с вами поближе, развеять некоторые мифы, ответить на частые вопросы, рассказать о себе, поделиться некоторыми мыслями, советами, инсайтами и инсайдами. Пойдёмте под кат, я вас со всеми познакомлю! Читать далее

  • Building a GPT-like Model from Scratch with Detailed Theory and Code Implementation
    HabrHabr
    Unlock the power of Transformer Neural Networks and learn how to build your own GPT-like model from scratch. In this in-depth guide, we will delve into the theory and provide a step-by-step code implementation to help you create your own miniGPT model. The final code is only 400 lines and works on both CPUs as well as on the GPUs. If you want to jump straight to the implementation here is the GitHub repo.Transformers are revolutionizing the world of artificial intelligence. This simple, but very powerful neural network architecture, introduced in 2017, has quickly become the go-to choice for natural language processing, generative AI, and more. With the help of transformers, we've seen the creation of cutting-edge AI products like BERT, GPT-x, DALL-E, and AlphaFold, which are changing the way we interact with language and solve complex problems like protein folding. And the exciting possibilities don't stop there - transformers are also making waves in the field of computer vision with the advent of Vision Transformers. Read more

  • Payment Village at PHDays 11: pentesting our online bank
    HabrHabr
    Hello everyone! We've already talked in our blog about how the Positive Hack Days 11 forum had a special Payment Village zone, where anyone could look for vulnerabilities in an online bank, ATMs, and POS terminals. Our competition to find vulnerabilities in an online bank is not new, but in recent years it has been somewhat supplanted by ethical hacking activities for other financial systems. In 2022, we decided to correct this injustice and created a new banking platform, making use of all our years of experience. We asked the participants to find typical banking vulnerabilities and report them to us. In the competition, the participants could play for either the "white hats" (participate in the bug bounty program of an online bank) or for the "black hats" (try to steal as much money from the bank as possible).

    HabrHabr
    Most people assume crypto and NFT are the same but both are different. NFTs are based on blockchain platforms that allow the minting and exchange of cryptocurrencies of a specific type.

Meanwhile one 1 crypto coin will be equal to one coin.In this article, we will discuss NFT games, like why they are trending and what features and functions are making them more advanced than traditional games. As the demand for NFT based is increasing day by day, then you can also churn this opportunity by developing your own game with the help of a crypto app development company. Before diving in, let’s know about the blockchain and NFTs.

  • Exploring the Capabilities and Implications of ChatGPT 3 in the Educational Technology Field
    HabrHabr
    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.
