Tutorial
Настал третий за 12 лет случай, когда в профессии программист-микроконтроллеров понадобилось вспомнить школьную математику. В этом тексте я представил перевод AppNote(а) «The mathematics of two-way ranging». Также добавил свои комментарии в те места, которые неочевидны при первом прочтении.
Тема нужна для определения расстояния между двумя радио трансиверами, которые могут определять моменты времени прихода и отправки радиоволны. Такое умеют делать UWB трансиверы, например чип DW1000.

Tutorial
Last week, I introduced you to the world of onchain analysis and explored some of the ways it can be used to gain insights into the cryptocurrency market.
Today, we’re taking things up a notch with a tutorial that will guide you through running your own onchain analysis. By the end of this tutorial, you’ll have the skills and knowledge you need to start analyzing blockchain data and making informed decisions about your cryptocurrency investments.
This tutorial is built around the Bitcoin blockchain, but many of the techniques are applicable to any other blockchains as long as they have wallets, balances, and transactions.

In this tutorial we’ll learn how to write cross-platform code in C using the system functions on popular OS (Windows, Linux/Android, macOS & FreeBSD): file management functions and file I/O, console I/O, pipes (unnamed), execution of the new processes. We’re going to write our own small helper functions on top of low-level userspace system API and use them so that our main code can run on any OS without modifications.

Wireless technologies *Conferences Gadgets Computer hardware Lifehacks for geeks
Review
TL;DR: All AI-based noise cancellations suck, only the physical cancellation technique works! And physical cancellation is implemented well only in Jabra devices yet, but other features suck them! All Bluetooth headsets suck too! So, no solution yet, just complaints!
The environment: I work in a pretty talky office room, where sit around 10 people, and all of them have many online conferences every day, including me.
So, silence in the room is a rare situation.
The problem: The main problem is that most of the microphones pick up all side talk pretty loud, which makes it very unpleasant for other people to listen to my voice in meetings!

But when we display content owned by other parties, we can’t fill the form with our data in a simple way.

Python *Programming *Studying in IT
Tutorial
Programming textbooks usually do not indulge us with variety of examples. In most manuals, exercises are similar to each other and not particularly interesting: create another address book, draw a circle using turtle, develop a website for a store selling some kind of «necessary» advertising nonsense. Too far from the authentic imitation of «The Matrix». Although…
How about taking over the control and starting to invent exercises yourself?
Would you like to write your own personal little «Matrix»? Of course, not the one with skyscrapers, stylish phones of the time, and the ubiquitous invincible Agent Smiths. We will need a couple of more months of learning for that. But any beginner programmer can write a model of the cult splash screensaver with the green streams of digits flowing down the screen.
Let’s try to creat it in the «great and mighty» Python.

This is a translation of my own article
The release of NewLang language with a brand new «feature» is coming, a remodeled version of the preprocessor that allows you to extend the language syntax to create different DSL dialects using macros.
What is it about?
DSL (Subject Oriented Language) is a programming language specialized for a specific application area. It is believed that the use of DSL significantly increases the level of abstractness of the code, and this allows to develop more quickly and efficiently and greatly simplifies the solution of many problems.
Conditionally, we can distinguish two approaches to DSL implementation:
- Development of independent syntax translators using lexer and parser generators to define the grammar of the target language through BNF (Backus–Naur form) and regular expressions (Lex, Yacc, ANTLR, etc.) and then compiling the resulting grammar into machine code.
- Development or integration of the DSL dialect into a general-purpose language (metalanguage), including the use of various libraries or special parsers / preprocessors.
We will talk about the second option, namely the implementation of DSL on the basis of general-purpose languages (metalanguages) and the new implementation of macros in NewLang as the basis for DSL development.

GIMP (GNU Image Manipulation Program) is a free and open-source image editing software that provides users with a wide range of tools for editing and manipulating digital images. Python is a high-level programming language that is often used for scripting and automation tasks. The combination of GIMP and Python provides a powerful platform for users to create custom image editing plugins that can automate repetitive tasks, extend the functionality of GIMP, and customize the software to suit their specific needs.
Python provides a flexible and easy-to-learn language for writing GIMP plugins. GIMP provides an API (Application Programming Interface) that allows Python scripts to interact with the image editing program Python plugins for GIMP can be used for a wide range of tasks, including automating repetitive tasks, enhancing the functionality of GIMP, and customizing the software to suit specific needs.
Some examples of tasks that can be automated using Python plugins include batch processing of images, resizing and cropping of images, and converting file formats.
Plugins can also add new features to GIMP, such as custom brushes, filters, and effects. Additionally, plugins can be used to create custom user interfaces that enable users to interact with GIMP in new and unique ways.

As a Product Manager who has worked on the development of delivery route optimisation software for 10+ years, I see that modern technologies can significantly improve the optimisation process and deliver better solutions.
AI, machine learning, and other modern technologies have the potential to revolutionise the way delivery routes are optimised in the future.
With the increasing availability of data and the advancement of AI and machine learning algorithms, it is becoming possible to develop more sophisticated prediction models that can be integrated into optimisation algorithms to make more accurate and informed decisions about route planning and scheduling. Machine learning algorithms can be trained to predict customer demand based on historical sales data and other market trends, allowing businesses to optimise their delivery schedules and routes accordingly. AI can also be used to optimise delivery schedules based on customer preferences and other relevant factors.
Blockchain technology could be used to create a secure, decentralised database of information about deliveries, including information about the products being shipped, the route they are taking, and the status of the delivery.
This could help increase transparency and accountability in the delivery process as well as reduce the risk of fraud and theft.
Internet of Things (IoT) devices, such as sensors and GPS trackers, may collect real-time data about delivery vehicles and their surroundings. This data could be analysed and used to optimise delivery routes in real time, as well as to track the location of deliveries and monitor the condition of the products being shipped.

I believe listicles have a huge potential for testing demand hypotheses.
Have you tried using listicles for your demand validation? If so — let us know in the comments how this worked for you.
Do you know these «Top N something something» kind of articles? Like:
— 5 best GPS vehicle trackers
— The 14 hair growth products that actually work
— Top 10 Best CRM Software Tools in 2023
They are often referred to as «listicles» — articles presented in the form of a list.
I love them — they make picking a new phone, a movie to watch, an app to install much easier. I also use them at work all the time while looking for solutions to everyday challenges.
So what if we use one of them to benchmark our product against the best available alternatives?

Яндекс не сканирует индекс карты сайта

Изменено 2 года, 5 месяцев назад
Просмотрено 78 раз
Я отправил файл индекса карты сайта (тот, который ссылается на другие карты сайта, содержащие фактические URL-адреса, которые поисковые системы должны сканировать). Он сжат GZip.
Используя инструмент проверки карты сайта Яндекса, он сообщает мне, что она действительна, имеет 202 ссылки и не содержит ошибок.
Однако в Яндекс Вебмастере он отображается маленьким серым значком в колонке статуса. При нажатии пишет «Не проиндексировано».
Яндекс не индексирует URL-адреса, указанные в файле, все новые. Хотя он заявляет, что ознакомился с картой сайта.
Есть идеи, что может быть не так?
ОБНОВЛЕНИЕ
В этом случае мои карты сайта были заблокированы от Яндекс Бота. Убедитесь, что ваши карты сайта можно сканировать с помощью инструмента анализа robots.txt. Валидатор карты сайта скажет, что они хороши, и не покажет ошибку, если они не доступны для сканирования.
- yandex
- yandex-webmaster-tools
Яндекс перечисляет некоторые причины, по которым карта сайта будет отображаться как не проиндексированная здесь. Может просто еще не обработано.
Файл Sitemap может быть не проиндексирован по нескольким причинам:
- Робот недавно просканировал файл Sitemap и еще не обработал его.
