Linux and Unix Training in Atlanta, Georgia

Once again Java tops C as the number one sought after programming language on the internet. According TIOBE Programming Community Index for February 2013 and five search engines: Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu, Java regained its position after being bumped by C in May 2012.

Despite the recent urging by the U.S. Department of Homeland Security of computer users to disable or uninstall Java due to a flaw in Runtime Environment (JRE) 7, Java, has increased its market share of all languages by (+2.03%) in the past six months. The jump in Java’s popularity does not come as a surprise as the Android OS claims massive success in the mobile space. The top twelve programming languages listed in the index are:

Java
C
Objective-C
C++
C#
PHP
Python
(Visual) Basic
Perl
Ruby
Java Script
Visual Basic.NET

Also rising, Python and PHP which are competing to becoming the most popular interpreted language.

.NET Core 3 Release, Major Benefits

[Mar, 26, 2019] |
Tags:

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)

Is Cloud Computing Safe for Your Business?

[Jul, 11, 2013] |
Tags:

As the cloud buzz is getting louder with every passing day you are tempted to take the big leap into the cloud but may have restrained yourself paranoid by ad infinitum cloud security discussions floating on the web. No one can deny the fact that your data is the lifeblood your business. So, undoubtedly its security is of paramount importance for survival of your business. As cloud computing is a paradigm shift from the traditional ways of using computing resources, you must understand its practical security aspects.

Is Cloud Computing Safe?

There can’t be a binary answer (Yes or No) to this question. But with my experience and as an authority on the subject I can tell you that technologies enabling Cloud services are not in any way less secure than the traditional or on-premise hosting model. Also, with the evolution of technology, the cloud providers are getting matured and almost all the providers are offering built-in security, privacy, data backups and risk management as a part of their core service.If you are not a big IT company then you must ask yourself:

· Can an on-premise solution or a traditional hosting provider match the same level of standard security and privacy requirement as provided by the specialist cloud provider whose core competency lies in providing state of the art security and privacy?

Fixing Copy and Paste for Remote Desktop

[May, 31, 2014] |
Tags:

From Brennan's Blog which is no longer up and running:

I use Remote Desktop all the time to work inside of my development systems hosted by Microsoft Virtual Server. I use the host system to browse the web for documentation and searches as I work and when I need to copy some text from the web browser I find many times the link between the host clipboard and the remote clipboard is broken. In the past I have read that somehow the remote clipboard utility, rdpclip.exe, gets locked and no longer allows the clipboard to be relayed between the host and the client environment. My only way to deal with it was to use the internet clipboard, cl1p.net. I would create my own space and use it to send content between environments. But that is a cumbersome step if you are doing it frequently.

The only way I really knew to fix the clipboard transfer was to close my session and restart it. That meant closing the tools I was using like Visual Studio, Management Studio and the other ancillary processes I have running as I work and then restarting all of it just to restore the clipboard. But today I found a good link on the Terminal Services Blog explaining that what is really happening. The clipboard viewer chain is somehow becoming unresponsive on the local or remote system and events on the clipboards are not being relayed between systems. It is not necessarily a lock being put in place but some sort of failed data transmission. It then goes on to explain the 2 steps you can take to restore the clipboard without restarting your session.

Use Task Manager to kill the rdpclip.exe process
Run rdpclip.exe to restart it

The clipboard communications should be restored. My clipboard is currently working because I just restarted my session to fix it, but I wanted to test these steps. I killed rdpclip.exe and started it and was able to copy/paste from the remote to the host system. The next time my clipboard dies I will have to check to see if these steps truly do work.

why take Linux Unix Training with the hartmann software group?

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.
