Database selection cheat sheet: SQL or NoSQL?

PostgreSQL *Java *SQL *NoSQL *Go *

This is a series of articles dedicated to the optimal choice between different systems on a real project or an architectural interview.

This topic seemed relevant to me because such tasks can be encountered both at work and at an interview for System Design Interview and you will have to choose between these two types of DBMS. I plunged into this issue and will tell you what and how. What is better in each case, what are the advantages and disadvantages of these systems and which one to choose, I will show with several examples at the end of the article.

Building a GPT-like Model from Scratch with Detailed Theory and Code Implementation

Open Data Science corporate blog Python *Machine learning *Artificial Intelligence Natural Language Processing *

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.

Payment Village at PHDays 11: pentesting our online bank

Positive Technologies corporate blog Information Security *Payment systems *Entertaining tasks Web services testing *

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).

Important Role of Cryptocurrency in NFT Game Development

Artificial Intelligence

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. The basic difference between crypto and NFTs is that two NFTs can not have equal value. 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.

BGP Route Leak prevention and detection with the help of the RFC9234

Qrator Labs corporate blog Information Security *Network technologies *Network standards *

All the credit is due to the RFC’s authors: A. Azimov (Qrator Labs & Yandex), E. Bogomazov (Qrator Labs), R. Bush (IIJ & Arrcus), K. Patel (Arrcus), K. Sriram.

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.

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

Artificial Intelligence

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.

Creating UITableView with a dynamic header

Xcode *Swift *

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?

Make first deb-src package by example cri-o

Configuring Linux *Open source **nix *Development for Linux *


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.

Codepast people – programmers’ sunset

Programming *Science fiction

— 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.
