CustomTkinter is a python UI-library based on Tkinter, which provides new, modern and fully customizable widgets. They are created and used like normal Tkinter widgets and can also be used in combination with normal Tkinter elements. The widgets and the window colors either adapt to the system appearance or the manually set mode ('light', 'dark'), and all CustomTkinter widgets and windows support HighDPI scaling (Windows, macOS). With CustomTkinter you'll get a consistent and modern look across all desktop platforms.

Nbb’s main goal is to make it easy to get started with ad hoc CLJS scripting on Node.js.
Additional goals and features are:
• Fast startup without relying on a custom version of Node.js.
• Small artifact (current size is around 1.2MB).
• First class macros.
• Support building small TUI apps using Reagent.
• Complement babashka with libraries from the Node.js ecosystem.

Jepsen is a Clojure library. A test is a Clojure program which uses the Jepsen library to set up a distributed system, run a bunch of operations against that system, and verify that the history of those operations makes sense. Jepsen has been used to verify everything from eventually-consistent commutative databases to linearizable coordination systems to distributed task schedulers. It can also generate graphs of performance and availability, helping you characterize how a system responds to different faults.

Hex Fiend — is a fast and clever open source hex editor for macOS.

- Insert, delete, rearrange. Hex Fiend does not limit you to in-place changes like some hex editors.
- Work with huge files. Hex Fiend can handle as big a file as you’re able to create. It’s been tested on files as large as 118 GB.
- Small footprint. Hex Fiend does not keep your files in memory. You won’t dread launching or working with Hex Fiend even on low-RAM machines.
- Fast. Open a huge file, scroll around, copy and paste, all instantly. Find what you’re looking for with fast searching.
- Binary diff. Hex Fiend can show the differences between files, taking into account insertions or deletions. Simply open two files in Hex Fiend and then use the File > Compare menus.
- Smart saving. Hex Fiend knows not to waste time overwriting the parts of your files that haven’t changed, and never needs temporary disk space.

Stable Diffusion is a latent text-to-image diffusion model. Thanks to a generous compute donation from Stability AI and support from LAION, we were able to train a Latent Diffusion Model on 512x512 images from a subset of the LAION-5B database. Similar to Google's Imagen, this model uses a frozen CLIP ViT-L/14 text encoder to condition the model on text prompts. With its 860M UNet and 123M text encoder, the model is relatively lightweight and runs on a GPU with at least 10GB VRAM. See this section below and the model card.

Generating secrets in Clojure.

Generating secrets is a very important part of any data-sensitive application. In this article, I’m going to tell you about a low-level library that helps to generate secrets in Clojure.

If you’re familiar with Python, you might have heard of secrets module from Python’s standard library. Well, the secrets.clj is just like Python’s secrets, but for Clojure.

How async/await works in Python.

Code written in the async/await style looks like regular synchronous code but works very differently. To understand how it works, one should be familiar with many non-trivial concepts including concurrency, parallelism, event loops, I/O multiplexing, asynchrony, cooperative multitasking and coroutines. Python's implementation of async/await adds even more concepts to this list: generators, generator-based coroutines, native coroutines, yield and yield from. Because of this complexity, many Python programmers that use async/await do not realize how it actually works. I believe that it should not be the case. The async/await pattern can be explained in a simple manner if you start from the ground up. And that's what we're going to do today.

Beej's Guide to Network Programming.

Hey! Socket programming got you down? Is this stuff just a little too difficult to figure out from the man pages? You want to do cool Internet programming, but you don’t have time to wade through a gob of structs trying to figure out if you have to call bind() before you connect(), etc., etc.

Well, guess what! I’ve already done this nasty business, and I’m dying to share the information with everyone! You’ve come to the right place. This document should give the average competent C programmer the edge s/he needs to get a grip on this networking noise.

Elliptic curves and ECDSA: everything to know to sign a transaction in Bitcoin from scratch.

The elliptic curve is a pretty simple concept. The Elliptic Curves Digital Signature Algorithm (ECDSA), which works on top of its properties, is used in most blockchains like Bitcoin, Ethereum, etc., and is even simpler. But it’s difficult to find a good explanation on the internet and build all the pieces together. But here it is! In this article, we will.

We will go through all the concepts needed to understand and implement this algorithm — one by one. By the end of this article, we will have a fully functioning demo from scratch, which can extract the public key from the private key, sign a message, and verify that the signature is correct. This implementation will only use the concepts described in this article. Moreover, it will take less than 100 lines of code.

This article is targeted mainly at developers, who want to finally understand ECDSA, but it will also be very useful for everyone else. It requires knowing no more than middle school math.

Python Type Checking.

In this guide, you will get a look into Python type checking. Traditionally, types have been handled by the Python interpreter in a flexible but implicit way. Recent versions of Python allow you to specify explicit type hints that can be used by different tools to help you develop your code more efficiently.

The Definitive Guide to Clojure on the JVM.

Clojure runs on the JVM and that is a huge asset to the Clojure language. In addition, Clojure was designed to be hosted. That means its semantics often defer to the underlying semantics of the host platform. All of that boils down to us needing to understand the Java ecosystem in order to get the most out of Clojure.

The Java ecosystem is big and it can be daunting. But fear not! You don't need to learn everything, and once you learn enough, it will be worth it. You will realize that it is not so intimidating.

This guide will be your . . . guide.
