A selection of datasets for machine learning:

• Data deaths and battles from the game of thrones — This data set combines three data sources, each based on information from a series of books.
• Global Terrorism Database — Over 180,000 terrorist attacks worldwide, 1970-2017.
• Bitcoin, historical data — Bitcoin data with an interval of 1 minute from selected exchanges, January 2012 — March 2019

This week I spent coding my very first public pet-app based on Telegram chat bot which acts as a Bitcoin wallet and allows to send and receive tips between Telegram users and other so-called “Lightning Apps”. I assume that you are familiar with Bitcoin & Telegram in general, i’ll try to post short and without deep jump into details. More resources about Bitcoin can be found here and Telegram is simply an instant messenger that allows you to create your custom apps (chat-bots) using their platform.

What are the key points of such app?

• Allows to rate other users ideas and answers with real value instead of
  ‘virtual likes’. This brings online conversation to completely new level
• Real example of working micro-payment app which can act with other entities
  over internet using open protocol
• All the modules are open-source projects and can be easy re-used and adjusted
  for your own project. App does not relay on third-party commercial services.
  Even it falls under e-commerce field, which is currently almost closed, the app
  is based on open solutions.

What are the use-cases?

something like this…

We used to think of Telegram as a reliable and secure transmission medium for messages of any sort. But under the hood, it has a rather common combination of a- and symmetric encryptions. Where's fun in that? And anyway, why would anyone trust their messages to the third-party?

TL;DR — inventing a private covert channel over users blocking each other.

• PyBuilder
• pynt
• Paver

RUM

• Take «yum» or «apt» package from the PGDG repository. For example, if you installed PostgreSQL from «postgresql-10» package, also install «postgresql-10-rum».
• Build from source code on github and install on your own (the instruction is there as well).
• Use as a part of Postgres Pro Enterprise (or at least read the documentation from there).

We are beyond excited to announce Windows Terminal! Windows Terminal is a new, modern, fast, efficient, powerful, and productive terminal application for users of command-line tools and shells like Command Prompt, PowerShell, and WSL.

Windows Terminal will be delivered via the Microsoft Store in Windows 10 and will be updated regularly, ensuring you are always up to date and able to enjoy the newest features and latest improvements with minimum effort.

There is a story about an experience of using Actor Model in one interesting project of developing an automatic control system for a theatre. Below I'll tell my impressions, no more than that.

Here is tree with 3 levels to start your journey as web developer.

Introduction

Ever since we announced Template IntelliSense, you all have given us great suggestions. One very popular suggestion was to have the Template Bar auto-populate candidates based on instantiations in your code. In Visual Studio 2019 version 16.1 Preview 2, we’ve added this functionality via an “Add All Existing Instantiations” option in the Template Bar dropdown menu. The following examples are from the SuperTux codebase. 

Here at Visual Studio App Center, we try to incorporate customer obsession in our day to day. Earlier this year we started an effort for widespread customer outreach to understand our users and guide product prioritization. The effort helped us gain a lot of insight and helped our prioritization last quarter. However, as we continue to grow, we unfortunately don’t have the capacity to reach out to as many customers as we would like.

To continue to engage with as many customers are possible, we created a GitHub repo specifically for this purpose. We’ve been using the repo to track monthly iterations from the team, feature requests, and community interest for certain features. We are making changes to align our priorities for the upcoming quarters based on what our customers are requesting.

I wanted to highlight some of the changes we’ve made to the Distribution service based off what we learned from customer outreach and feedback. All of these changes are available now:

• Distributing releases to multiple destinations
• Distribution releases to individual testers
• Turning off email notification for releases
• Disabling a release
• Make releases sortable

Code search and navigation are important features of any IDE. In Java, one of the commonly used search options is searching for all implementations of an interface. This feature is often called Type Hierarchy, and it looks just like the image on the right.

It's inefficient to iterate over all project classes when this feature is invoked. One option is to save the complete class hierarchy in the index during compilation since the compiler builds it anyway. We do this when the compilation is run by the IDE and not delegated, for example, to Gradle. But this works only if nothing has been changed in the module after the compilation. In general, the source code is the most up-to-date information provider, and indexes are based on the source code.

Finding immediate children is a simple task if we are not dealing with a functional interface. When searching for implementations of the Foo interface, we need to find all the classes that have implements Foo and interfaces that have extends Foo, as well as new Foo(...) {...} anonymous classes. To do this, it is enough to build a syntax tree of each project file in advance, find the corresponding constructs, and add them to an index.
