Cryptocurrency market valuation to hit $1 trillion this year. The market cap of cryptocurrency seems to just increase. Even though some of the individual ones are falling but cumulatively, the market cap seems to increase year-on-year.

According to the CEO of Kraken, Jesse Powell, cryptocurrencies would see accelerated growth. They would be able to pull back from the bottom to new highs.

According to him, there are many businesses revolving around cryptocurrencies now. Also, there are many people in the know-how of cryptocurrency is no

The Object base type and implementation of interfaces. Boxing

It seems we came through hell and high water and can nail any interview, even the one for .NET CLR team. However, let's not rush to microsoft.com and search for vacancies. Now, we need to understand how value types inherit an object if they contain neither a reference to SyncBlockIndex, not a pointer to a virtual methods table. This will completely explain our system of types and all pieces of a puzzle will find their places. However, we will need more than one sentence.

Now, let's remember again how value types are allocated in memory. They get the place in memory right where they are. Reference types get allocation on the heap of small and large objects. They always give a reference to the place on the heap where the object is. Each value type has such methods as ToString, Equals and GetHashCode. They are virtual and overridable, but don’t allow to inherit a value type by overriding methods. If value types used overridable methods, they would need a virtual methods table to route calls. This would lead to the problems of passing structures to unmanaged world: extra fields would go there. As a result, there are descriptions of value type methods somewhere, but you cannot access them directly via a virtual methods table.

This may bring the idea that the lack of inheritance is artificial

Most people assume that I studied computer science in university and that I’ve been coding since I was young. They’re usually surprised when I tell them that in fact I studied Marketing and Spanish and that although my brother taught me how to build a very basic web page in the early 2000s, I didn’t really start to learn to program until I was an adult with a job.

The truth of the matter is that my story isn’t unique. It’s simply not true that you have to be a whiz kid who’s been coding since they were 6 years old in order if you want to be able to program as an adult. There are tons of examples of people who also don’t have a technical background who either became full time programmers or just learned a new skill they enjoy using.

In this post, I’ll give you some advice that has served me well on my journey. My path is by no means the only path and depending on the situation you’re in might not be practical or right for you, but it is certainly a path, and I hope it helps you on your path to learning to computer.

Why do so many programmers hate UI work? Because it is tedious. Especially, for the Web, but other types of UI are only slightly easier. Layouts, margins, paddings — neverending stream of little tweaks to make it look OK on all sane environments, and somehow this freaking button sometimes overlaps that input field. Rrrr! And yes, it should not hang on button clicks, which means a lot of asynchronous programming, which is a nightmare.

And don’t even speak about aesthetics and usability! Choose right colours, element sizes and locations, find/draw images and put them where they fit, think about user workflows — isn’t it a designers’ or Ux specialists’ job?! Leave me alone, I’m a programmer. I work with backend layers, where everything is straightforward and linear, there are no buttloads of different environments to adjust to, and design is guided by mere logic without pesky fussing with ‘user friendliness’ and ’beauty’!
