Environment variables are really nice timesaver feature in Windows. As a quick reminder:
There is a special variable named ‘Path'; you can write paths to the folders that contain some files, for example:
The TLS protocol is designed to provide three essential services to all applications running above it: encryption, authentication, and data integrity. Technically, you are not required to use all three in every situation. You may decide to accept a certificate without validating its authenticity, but you should be well aware of the security risks and implications of doing so. In practice, a secure web application will leverage all three services.
The runtime hosting infrastructure for ASP.NET 5 is currently called the K Runtime Environment (KRE), which is a generic placeholder name until we finalize the official name. The KRE provides an environment that has everything a .NET app needs to run: a host process, CLR hosting logic, managed entry point discovery and so forth. The KRE was built for running cross-platform .NET Web applications, but it can run other types of .NET applications, too, such as console apps. The KRE is based on the same .NET CLR and base class libraries .NET developers have come to know and love, while enabling cross-platform support for running .NET applications on Windows, OS X and Linux.
The world has come a long way from the first context-sensitive C code editor in the early 1980s. Tooling and languages developed initially for desktop apps have been extended to encompass server, cloud and other environments. The Microsoft .NET Framework and Visual Studio provide state-of-the-art tools that greatly increase programmer efficiency. The .NET Framework tools and languages provide rich libraries and collaboration tools, and protect programmers from the most common mistakes.
With all the public open source repositories and cloud services there comes sensitive data ignoration problem. For example we can host our testing environment settings in Azure and save that hosting’s password / keys in configuration file. After some time we can suddenly get a huge bill because someone had used your credentials to install too many bitcoin miners in your cloud. Sure there are some other reasons to hide that information too
In this example we will use git as source control and SourceTree to make the process a bit easier for common routines.
The main idea is to:
1. Commit the file with dummy configuration settings (for example in .NET web project Web.config with database connection strings)
2. Ignore the changes to that file after that.
mm.. Just that simple.
To do that we can run the following command in git console:
git update-index –assume-unchanged FILEPATH
The command updates the index of the repository adding file ignoration without physical file deletion.
If you need to add some changes to the file after ignoring it in the index – you can run almost the same command:
git update-index –no-assume-unchanged FILEPATH
Removing file from indexing can add some problems during merging, but you can deal with them.. Think that’s better then publishing database credentials…
And the last one:
if you want to check which files were ignored from index run (marked as assume unchanged ):
git ls-files -v
If you are one of those kids, who use only GUI applications to complete the tasks here is something you’ll probably like:
for now i think the best tool for working with git or mercurial is SourceTree and it has one nice feature to automate the tasks: Custom Actions.
For the commands above you can do the following:
Then right click the file you want to temporary ignore in SourceTree and select the Custom Action.
The Secure Socket Layer is now essential for the secure exchange of digital data, and is most generally used within the HTTPS protocol. .NET now provides the Windows Communication Foundation (WCF) to implement secure communications directly. Matteo explains the TLS/SSL protocol, and takes a hands-on approach to investigate the SslStream class to show how to implement a secure communication channel
TypeScript provides excellent support for interfaces. For the beginners:
What is the interface?
Lets see if analogy can help here: for example lets take a factory. a factory requires that all the engines being built have a standard “interface” (for example 2 buttons: green/red, start/stop). So that when the new engine comes out we don’t need to study some new technics – there are still that 2 buttons from the mental example. If we change the physical engines with classes – then the consistent behavior in all that classes can be explained in the interface.
For example in TypeScript interface can be used to deny compilation in case some class has not implemented the needed functionality. Interface definition keyword is `interface`.
Any browser. Any host. Any OS. Open Source.
Lets start by checking types that can be used for static typing and special Any type.
There are 3 primitive types in TypeScript: string, number and boolean.
