In this article, we will learn about autofill methods for input fields/forms in WebView used inside of an android app. I’d like to stress that the main topic is the autofill in WebView, because, when filling standard EditText views in the app — no issues arise. 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.

Programming *Algorithms *

Opinion

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,

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?

Open source *PostgreSQL *Java *OpenStreetMap *

Translation

I will continue the story «How to put the whole world into a regular laptop: PostgreSQL and OpenStreetMap» with secrets about OpenStreetMap geodata, on which many companies have built their business, but not everyone shares the details. .. Well, today we will open crucial details.

The OSM database in PosgreSQL after loading from the dump takes up more than 587 GB. This is already a large database by the standards of a DBMS, and one huge table for each type of object will not work. For manageability, such data must be partitioned, it’s good that PostgreSQL supports declarative data partitioning. It remains only to figure out how to split geographical data. After searching and comparing, the h4 hierarchical hexagonal geospatial indexing system came to rescue. All this was implemented in my openstreetmap_h4 project for fast processing and loading of the world dump into the PostGIS database.

I considered following options from geopartitioning systems…

10 кодов HTML и CSS, которые должны знать все блоггеры

В сегодняшней статье я познакомлю вас с наиболее распространенными кодами HTML и CSS, которые вы должны знать как блогер.

В WordPress отличный редактор, а с появлением блочного редактора Gutenberg он стал еще лучше.

Но иногда просто необходимо немного знать HTML! Это очень легко узнать. Вам не нужно быть веб-разработчиком, чтобы это понять.

Вы можете использовать необработанный HTML в следующих ситуациях:

• Добавление таких элементов, как окно обо мне, на боковую панель
• Изменение стиля или толщины шрифта для определенного текста
• Очистка HTML-кода, скопированного в ваше сообщение откуда-либо еще
• Добавление дополнительных стилей, которые редактор блоков не предоставляет

Что такое HTML?

HTML означает H yper T ext M arkup L язык. Это язык кодирования, используемый для создания веб-страниц.

Каждый элемент на веб-странице начинается с открытой тег и заканчивается соответствующим закрывающим тегом / . Теги должны быть окружены < и > .

Например:

• Это впереди

• Это абзац

Теги могут содержать атрибуты, которые позволяют предоставлять дополнительную информацию, например в качестве исходного URL-адреса изображения и текста ALT для ссылки.

Что такое CSS?

CSS означает C ascading S tyle S heet и является языком, используемым для стиля HTML .

Код CSS обычно содержится в файле, на который есть ссылка в разметке HTML, например:

Вы также можете добавить CSS непосредственно в HTML. Здесь мы сообщаем браузеру, что все 9Элементы 0023 h2 должны иметь размер шрифта 28 пикселей.

 <стиль>
ч2 {
размер шрифта: 28px;
}
 

Другой способ добавить CSS — встроенный , который влияет только на текущий элемент. Здесь мы сообщаем браузеру, что конкретный элемент h2 должен иметь размер шрифта 48 пикселей.

  
Это заголовок
 

Вы можете добавлять классы к элементам, на которые есть ссылки в связанном файле CSS. Здесь мы превращаем обычную ссылку в кнопку, добавляя button class:

Как начать блог

Как просмотреть и отредактировать HTML

Вы можете просмотреть HTML любого блока, щелкнув его, а затем выбрав Редактировать как HTML в меню.

Оттуда вы можете вносить дополнительные изменения в HTML, которые не предусмотрены в настройках блока.

Чтобы вернуться к визуальному представлению, выберите Редактировать визуально из меню.

Добавление изображений

Добавьте изображения с помощью тега . Где атрибут src содержит ссылку на изображение.

Вы можете указать высоту и ширина изображения в пикселях с использованием атрибутов height и width .

Рекомендуется добавьте атрибут ALT для улучшения SEO, например:

Связанное чтение: WordPress Blog SEO — контрольный список из 17 пунктов перед запуском

Базовая ссылка

Добавьте ссылки, используя тег:

 Начните свой блог сегодня! 

Начните свой блог сегодня!

Где href — исходный URL-адрес ссылки, а текст между тегами и — отображаемый текст.

Ссылка на адрес электронной почты

Если вы добавите адрес электронной почты в атрибут href , вы можете открыть почтовое приложение своего пользователя, просто добавьте mailto: перед почтовым адресом.

 Напишите мне сегодня! 

Напишите мне сегодня!

Ссылки на изображения

Вы можете превратить изображение в большую ссылку, окружив его тегами привязки, например:

Не забудьте указать «nofollow»

Если ссылка предназначена для внешнего сайта, вам следует добавить атрибут «nofollow», чтобы предотвратить потерю рейтинга страницы.

 Поиск в Google 

Узнайте больше о nofollow и о том, как можно автоматически добавить атрибут ко всем внешние ссылки здесь: Этот твик может немедленно улучшить SEO-рейтинг.

Заголовки и параграфы

Для заголовков используйте формат x 9Тег 0023 > , где x — число от 1 до 6, соответствующее уровню заголовка, где

Это заголовок верхнего уровня:

 
Это заголовок сообщения
 

Это заголовок второго уровня:

 
Это подзаголовок
 

Для абзацев используйте

.

 
Это абзац текста.
 

Списки

Списки отлично подходят для выдвижения аргументов за или против аргумента. Читатели любят видеть список! Списки могут быть маркированы или пронумерованы.

Для маркированных (неупорядоченных) списков используйте теги

 

Элемент 1
Элемент 2
Элемент 3.
Элемент 4.
