Using the async/await in typescript, you can flatten the callback in node, which is more readable than the promise-type chain call. Personally, it is the preferred solution to the callback hell.

Microsoft SQL Server is becoming more and more friendly for developers of data platforms. For example, it has been natively supporting XML for many years, and in this trend, it is now possible to use the built-in JSON in SQLServer2016. This is especially valuable for the parsing of some big data interfaces. Compared to what we do now, such as using CLR or custom functions in SQL, the new built-in JSON can greatly improve performance, while optimizing programming and adding and removing changes and other methods.

But I always feel the shortcomings of what! "On paper to get the final feeling shallow, know this matter to preach", yes, is the actual combat! This time let's take a look at some of the operation of the file directory skills, may lead us to think from different angles, and thus out of the corner of thinking!

Holographic applications need to be able to run smoothly in a wide range of environments, while maintaining stable performance and better user comfort at all times. This article mainly discusses the content of this aspect.

Presumably every person who configures spring has more or less learned some basic knowledge of SPRINGMVC, maybe some people use myeclipse or eclipse to build a project, I will tell you that the steps here are very similar, In MyEclipse you need to build a Web project, then add Spring support, follow the jar package yourself to download the import, other configurations and this article indistinguishable. But I recommend that you use idea, this compiler is recognized as the best Java compiler, presumably writing code will be more comfortable and fast!

A series of meanings is that the elements have a fixed order of arrangement, so the operation of the elements must be in order: the previous operation is completed and then the next element is calculated. In this way, stream should not be a good parallel computing tool. However, the parallel operation supported by FS2 is not a data element but a Stream is an arithmetic unit: and our Assembly code does not provide a definition of the main function. The last line shows that these error hints are reported by LD. So if we use GCC as a link, GCC is actually calling LD to link the target file crt1.o with the hello.o we wrote. http://www.cnblogs.com/nyctu/

In the context of web development, "middleware" usually means "a part of the application that wraps the original application and adds some additional functionality". The concept doesn't always seem to be understood, but I think the middleware is great.
First of all, a good middleware has a responsibility to be pluggable and self-contained. This means that you can embed your middleware at the interface level and he can run it directly. It doesn't affect the way you encode, it's not the framework, it's just a layer of your request to process it. There is no need to rewrite your code, if you want to use a function of the middleware, you can help him to plug in there, if you do not want to use, you could directly remove.
Throughout the go language, middleware is very common, even in standard libraries. Although it will not be so obvious at first, the function Striptext or Timeouthandler in the standard library is what we want to define and what the middleware looks like, processing requests and corresponding when they wrap your handler, and handle some extra steps. http://www.cnblogs.com/xdrtuj/
Typically a session holds a lock on a resource, and another session is blocking (blocking) when it requests the resource. This is a situation that DBAs often encounter. When a SQL statement is blocked, many people want to see the source of the blocking (which SQL statement blocks which SQL), which makes it easy to locate the problem intuitively and concisely. But many times, in many scenarios, we can't or cannot easily locate the blocker SQL statement through SQL statements, and of course we can easily find the blocked SQL statement and the lock resource it waits for. Let's take a look at this type of scenario for the SQL Server database and then analyze this scenario for the Oracle database. If there are deficiencies, please note.

The data file itself is created in a single primary filegroup. By default, in the primary filegroup, SQL server stores the data (user tables, system tables, and so on) that are known. What is the purpose of the additional files and filegroups? Let's see.

Does that mean we can discard the XML and start using JSON? Of course not, it depends on the purpose of the data output processing. If you have an external service that interacts with external data through XML and the schemas inside and outside are consistent, then you should use XML data types and native functions. If you are targeting a micro-service architecture or dynamic metadata and data storage, you should take advantage of the latest JSON functions.
