For people, who owned a pager before, and want to know how it works, this article will be useful.
The C++ Core Guidelines’ Lifetime Profile, which is part of the C++ Core Guidelines, aims to detect lifetime problems, like dangling pointers and references, in C++ code. It uses the type information already present in the source along with some simple contracts between functions to detect defects at compile time with minimal annotation.

Flutter provides a modern react-style framework, rich widget collection and tooling, but there’s nothing similar to Android’s guide to app architecture.
Indeed, there’s no ultimate architecture that would meet all the possible requirements, yet let’s face the fact that most of the mobile apps we are working on have at least some of the following functionality:
Taking this into account I have created a sample app that is solving exactly the same problem using three different approaches to the architecture.
If you have dabbled into microchip photographing before, then this article will probably not offer much to you. But if you want to get into it, but don’t know where to start, then it’s exactly for you.
Before we start, a fair warning: while the procedure is quite entertaining, at first it’ll probably be physically painful. The chemicals used during the process are toxic, so please handle them carefully – that way it’ll still hurt, but less so. Also, if you have even a slight amount of common sense, conduct the procedure in a fully-equipped chemical laboratory under supervision of trained professionals: we’ve had to deal with people who tried to do it at home immediately after reading the guide. And finally: if you don’t know whether you need to pour acid into water or water into acid without a Google search and don’t realize what this lack of knowledge will entail – stop reading this immediately and go to a chemistry 101 course in a local college or something.
Hi. My name is Michael Kapelko. I've been developing software professionally for more than 10 years. Recent years were dedicated to iOS. I develop games and game development tools in my spare time.
Today I want to share my experience of teaching kids to program. I'm going to discuss the following topics:

I like writing React code. This might be an odd introduction to a story about Vue, but you need to understand my background to understand why I’m here discussing Vue.
I like writing React code and I hate reading it. JSX is a neat idea for assembling the pieces together fast, Material-UI is amazing solution for bootstrapping your next startup’s UI, computing CSS from JS constants allows you to be very flexible. Yet reading your old JSXs feels awful – even with scrupulous code review practices you might scratch your head not once as you try to figure the intricate nesting of the components.
I’ve heard many things about Vue—the not so new kid on the block—and I finally decided to get my feet wet; bringing in all my mental luggage of React and Polymer (and Angular, but let’s not talk about that).
This article contains a brief squeeze from my own experience and that of my colleagues, with whom I had been fighting incidents day and night. And many incidents would never have occurred if all these microservices that we love so much were written at least a little more carefully.
Unfortunately, some programmers seriously believe that a Dockerfile with any team at all inside is a microservice in itself and can be deployed even now. Dockers are running — money are incoming. This approach turns into problems starting from performance degradation, inability to debug, service failures and ending in a nightmare called Data Inconsistency.
If you feel that the time has come to launch one more app in Kubernetes / ECS / whatever, then I have something to object to.
Apple Swift version 5.0 (swiftlang-1001.0.45.7 clang-1001.0.37.7) Target: x86_64-apple-darwin18.2.0 ABI version: 0.6
Swift apps no longer include dynamically linked libraries for the Swift standard library and Swift SDK overlays in build variants for devices running iOS 12.2, watchOS 5.2, and tvOS 12.2. As a result, Swift apps can be smaller when deployed for testing using TestFlight, or when thinning an app archive for local development distribution.Application Binary Interface stability is coming! And this is excellent news. I think this is the one of the most significant issues at the moment with Swift. Not because of side-effects but because of Swift’s failure to deliver on previous promises. Anyway, I even know people who rewrite their Apple Watch extensions to Objective C to reduce the size of binary (something like 15MB vs ~1MB in Objective C). If you want to know more about the state of ABI, follow the links: Swift — ABI Dashboard and Swift ABI Stability Manifesto.
Visual Studio 2019 Preview 2 is out! And with it, a couple more C# 8.0 features are ready for you to try. It’s mostly about pattern matching, though I’ll touch on a few other news and changes at the end.
Have you ever noticed that you were busy all day, however, you've done nothing or at X-mas evening you experience an epiphany that nothing was done during the year? If your answer is "yes", you should improve your time management skills. According to Wikipedia, time management is the process of planning and exercising conscious control of time spent on specific activities, especially to increase effectiveness, efficiency and productivity. Nevertheless, how can we deal with it?
