Overview:
· Virus is a piece of code that is secretly introduced into a system in order to corrupt it or destroy data
Unlike Java, Python does not have a string contains method. Instead, use the in operator or the find method. The in operator finds treats the string as a word list whereas the find method looks for substrings. In the example shown below, 'is' is a substring of this but not a word by itself. Therefore, find recoginizes 'is' in this while the in operator does not.
s = "This be a string"
if s.find("is") == -1:
print "No 'is' here!"
else:
print "Found 'is' in the string."
if "is" in s:
print "No 'is' here!"
else:
print "Found 'is' in the string."
#prints out the following:
Found 'is' in the string
No 'is' here!
Last year, Hewlett-Packard purchased Autonomy for $10 billion, enduring a number of arrows from its competitor Oracle. What a difference a year is!
Since the purchase HP saw the leaving of Autonomy CEO Mike Lynch, which was not on friendly terms. It also saw the departure of the whole original management team and 20 percent of the staff. Now, the question is whether or not HP will see its move compensate or become another WebOS-style fiasco, marking the company needs to stay with hardware.
On March 6 of this year, Microsoft's .NET Foundation released its third preview release of .NET Core 3 — which is its free and open-source framework for developing apps on Windows, MacOS and Linux — with an official release scheduled for later this year. This release brings a wealth of new features and enhancements. This includes the following:
1. Windows Desktop Support
One of the biggest additions to version 3.0 of the framework is the ability to develop Windows desktop applications. The new Windows Desktop component lets you build applications using either the Windows Presentation Foundation (WPF) graphical subsystem or the Windows Forms graphical class library. You can also use Windows UI XAML Library (WinUI) controls in your applications.
The Windows Desktop component is only supported and included on Windows installs.
2. Support for C# 8
The new framework has support for C# 8, which includes not only the ability to create asynchronous steams but features such as:
Index and Range data types
Using declarations
Switch expressions
The Index and Range data types make array manipulation easier, while Using declarations ensure that your objects get disposed once they are out of scope. Finally, Switch expressions extend Switch statements by allowing you to return a value.
3. IEEE Floating-Point Improvements
The new framework includes floating point APIs that comply with IEEE 754-2008. This includes fixes to both formatting and parsing as well as new Math APIs such as:
BitIncrement/BitDecrement
MaxMagnitude/MinMagnitude
ILogB
ScaleB
Log2
FusedMultiplyAdd
CopySign
4. Support for Performance-Oriented CPU Instructions
The new framework includes support for both SIMD and Bit Manipulation instruction sets, which can create significant performance boosts in certain situations, such as when you are processing data in parallel.
5. Default Executables
With the new framework, you can now produce framework-dependent executables by default without having to use self-contained deployments.
6. Local dotnet Tools
In the previous version of the framework, there was support for global dotnet tools. But the current version adds support for local tools as well. These tools are associated with a specific disk location, and this allows you to enable per-repository and per-project tooling.
7. Support for MSIX Deployments
The new framework supports MSIX, which is a Windows app package format that you can use when deploying Windows desktop applications.
8. Built-In and Fast JSON Support
In prior versions of the framework, you had to use Json.NET if you wanted JSON support in your application. The framework, though, now has built-in support that is not only fast but also has low allocation requirements. It also adds 3 new JSON types, which include:
Utf8JsonReader
Utf8JsonWriter
JsonDocument
9. Cryptography Support
The new framework supports AES-GCM and AES-CCM ciphers. It also supports the importing and exporting of asymmetric public and private keys from a variety of formats without the need of an X.509 certificate.
Platform Support
.NET Core 3 supports the following operating systems:
Alpine: 3.8+
Debian: 9+
Fedora: 26+
macOS: 10.12+
openSUSE: 42.3+
RHEL: 6+
SLES: 12+
Ubuntu: 16.04+
Windows Clients: 7, 8.1, 10 (1607+)
Windows Servers: 2012 R2 SP1+
The framework further supports the following chips:
x64 (Windows, macOS and Linux)
x86 (Windows)
ARM32 (Windows and Linux)
ARM64 (Linux)

the hartmann software group advantage
A successful career as a software developer or other IT professional requires a solid
understanding of software development processes, design patterns, enterprise application architectures,
web services, security, networking and much more. The progression from novice to expert can be a
daunting endeavor; this is especially true when traversing the learning curve without expert guidance. A
common experience is that too much time and money is wasted on a career plan or application due to misinformation.
The Hartmann Software Group understands these issues and addresses them and others during any training engagement.
