Automation can be an exhilarating, albeit exhausting, journey—especially for those just dipping their toes into it. The tasks are often labeled as "interesting" or "non-standard," which, let’s be honest, often translates to "challenging" or even "impossible." Among these challenges, one question halts around 50% of novice automators in their tracks: How to bypass CAPTCHA!

Selenium CAPTCHA Bypass with Tokens or Clicks? Continuing the Speed Comparison
In my previous article, Puppeteer CAPTCHA bypass: Tokens or Clicks? Let’s Break It Down (which I also published on Dev.to), I compared two CAPTCHA bypass methods (clicks and tokens) using Puppeteer. I also announced that in the next article (this one), I would conduct a practical comparison of the same methods using Selenium. This will complete the CAPTCHA bypass picture, so to speak. Well, let’s not waste time and get straight to the point.
The Implicit Reparameterization Trick in Action: Python Library for Gradients Computation
The explicit reparameterization trick is often used to train various latent variable models due to the ease of calculating gradients of continuous random variables. However, due to its peculiarities, explicit reparameterization trick is not applicable to several important continuous standard distributions, such as mixture, Gamma, Beta and Dirichlet.
An alternative method for calculating reparameterization gradients relies on implicit differentiation of cumulative distribution functions. The implicit reparameterization trick is much more expressive and applicable to a wider class of distributions
This article provides an overview of various reparameterization tricks and announces a new Python library, irt.distributions
, for sampling from various distributions using the implicit reparameterization trick.
Advanced CAPTCHA Bypass Techniques for SEO Specialists with Code Examples
Every SEO professional has encountered CAPTCHA. If not, they are either not professionals, misunderstand the term SEO (possibly confusing it with SMM or CEO), or are very new to this challenging field.
One could endlessly deny and argue that CAPTCHA is overrated and does not deserve significant resources. But these arguments end the moment one needs data from a search engine result page, like Yandex, without knowledge of XML requests… Or, say, a client wants to scrape the entire Amazon (just because they do) and offers good pay...

Amazon parsing on easy level and all by yourself
I came across a script on the Internet that allows you to parse product cards from Amazon. And I just needed a solution to a problem like that.
I wracked my brain while looking for a way to parse product cards from Amazon. The problem is that Amazon uses different design options for different outputs, in particular – if you need to parse the cards with the search query "bags" – the cards will be arranged vertically, as I need it, but if you take, for example, "t-shirts" – then the cards will be arranged horizontally, and in such way the script falls into an error, it works out opening the page, but does not want to scroll.

Building blocks in programming languages
Practically all programming languages are built either on the principle of similarity (to make like this one, only with its own blackjack) or to realize some new concept (modularity, purity of functional calculations, etc.). Or both at the same time.
But in any case, the creator of a new programming language doesn't take his ideas randomly out of thin air. They are still based on his previous experience, obsession with the new concept and other initial settings and constraints.
Is there a minimal set of lexemes, operators, or syntactic constructs that can be used to construct an arbitrary grammar for a modern general-purpose programming language?

Reaching Steins;Gate | Amadeus implementation with Gemini API for newbies
Disclamer
Probably, you got here without google'ing, maybe from my profile or habr recommendations, so if you did, you must know that this article is my first experience in pure English technotext. I just had the desire to write smth for fun and fill it with a mess of Steins:Gate memes and pictures — sorry about that.
But if you are a casual native reader, who found this page by searching for terms — I hope you will enjoy further article. Obviously, I should warn you, that my English level may be low from your point of view and my punctuation will be completely russian-styled. Of course, I don't expect any feedback from readers, because of a few english-speaking verified users on this resource)
So, you may be here accidentally only if you are really keen on Steins;Gate series. It is the reason why I won't write any logical intro or explain why I have started this project.

How to Bypass reCaptcha in Selenium Automatically with Code Example
I based my approach on an English manual that caught my eye just a couple of days ago, and I decided to test it (since it's written by a captcha recognition service that I use, why not - by the way, guys from 2captcha - I accept thanks in the form of green bills, if you're interested))))
I've made some tentative attempts at automation and encountered a frequently arising problem: reCaptcha recognition.
Of course, I understand that there are many guides, manuals, and articles written on this topic, but let's agree - it's interesting to describe one's own experience.
Thus, without getting too lengthy and boring about why Selenium is necessary, how important it is for automation, when it appeared and who invented it, let's get to the crux:
To solve the problem, we'll use a demo page kindly provided by reCaptcha itself - https://recaptcha-demo.appspot.com/recaptcha-v2-checkbox.php:

How sqlalchemy uses greenlet to call an async Python function from a normal function
The Python language has two kind of functions — normal functions that you would use in most cases, and async
functions. The latter functions are used when performing network IO in an asynchronous manner. The problem with this division is that async
functions can only be called from other async
functions. Normal functions, on the other hand, can be called from any functions — however, if you call a normal function that does a blocking operation from an async
function, it will block the whole event loop and all your coroutines. These limitations usually mean that when writing an using Python`s asyncio
, you can`t use any of the IO libraries that you use when writing a synchronous application, and vice versa, unless a library supports usage both in sync and async applications.
Now, the question is, in case you are developing a large and complex library, that, say, allows users to interact with relational databases, abstracting away (some of) the differences between the SQL syntax and other aspects of these databases, and abstracting away the differences between the drivers for that database, how do you support both sync and async usage of your library without duplicating the code of your library? The way sqlalchemy is organized is that regardless of what database and driver for it you are using, you will be calling functions and methods related to Engine
, Connection
, etc classes, which will do some general work independent of database, then apply the logic specific to your database and finally, call the functions of your database driver to actually communicate with the database. If you are using Python`s asyncio
, the database driver will expose async
functions and methods, but the rest of the library that is driver‑independent would ideally remain the same. However, the issue is that that you can`t call the async
functions of the driver from the normal functions of the core of the library.
Detection of meterpreter sessions in Windows OS
Introduction
Hello Habr! This is a translation of my first article, which was born due to the fact that I once played with the types of meterpreter payload from the Metasploit Framework and decided to find a way to detect it in the Windows OS family.
Analysis
I will try to present everything in an accessible and compact way without delving into all the work. To begin with, I decided to create the nth number of useful loads (windows/meterpreter/reverse_tcp, shell/bind_tcp, shell_hidden_bind_tcp, vncinject/reverse_tcp, cmd/windows/reverse_powershell) to analyze what will happen in the system after their injection.
