Q: Distributed application programming is considered by many to be one of the hardest to learn and requires diverse knowledge in computer and communication technologies. This step is optional. However, it is very useful in understanding network topologies.  You need a good understanding of the Open Systems Interconnection (OSI) model, Ethernet, IP, TCP, UDP and HTTP before you start programming distributed applications.  For Windows-based programming, that would be any script that works with Windows Scripting Host. For Linux-based programming, Bash scripts and Perl will be sufficient. JavaScript is strongly recommended for this in both platforms for the following reasons:  It is supported by almost any scripting host in any operating system (Windows Scripting Host supports JavaScript by default, most Linux distributions has a package for JavaScript scripting console support). It is considered to be easier to learn by many developers. It has an ALGOL derived syntax which familiarizes you with much more other programming languages when you need to choose a second programming language (C, C++, C#, Java and J# all have ALGOL derived syntax). By learning JavaScript, you familiarize yourself with client-side scripting of web pages which is a bonus side-effect! Later, you can use more advanced programming techniques and paradigms according to your scripting language and what it supports. All scripting languages have some procedural programming aspects at some level. Learn what is necessary for doing that. Simple communications will suffice. Preferably, one that is a multi-paradigm language such as Python. Take a simple introduction to that second language. Java is considered by most programmers to be the language of choice for many reasons. However, C# is gaining momentum fast in this field. Java and C# are preferred for the following reasons:  They are object oriented programming languages which shields programmers in large teams from implementation details as they both supports components (units of code, pre-compiled, that perform a certain task and can be used in other programs). They support event-driven programming, as well as OO and procedural programming at some level. The framework that the language is built upon is distributed by nature (in the case of Java). The availability of many ready-made packages that deal with networking, both as open-source code and framework built-in packages; this makes it easier for programmers to build upon the work of others. more on the core features of the language, especially those supporting networking. Pay less attention to user-interface elements such as outputting, window design and techniques, and user-interface elements. This can be done using books, online tutorials or academic courses. However, understanding the architecture of distributed applications and its concepts is necessary.  It is recommended that you get at least an introduction to all of them. Most distributed application programmers do not stop at one or two programming languages, but learn at least one programming language on each operating system. That is because if you want your application to be "distributed", you should provide a version of it at least for each major operating system.  Common Object Request Broker Architecture (CORBA) Simple Object Access Protocol (SOAP) Asynchronous JavaScript and XML (AJAX) Distributed Component Object Model (DCOM) .NET Remoting XML Web Services
A: Tackle distributed applications programming. Take a speed introduction to telephony systems and their hardware. Familiarize yourself with networking hardware architectures and devices such as hubs, switches and routers. Take a course in networking protocols and essentials. Learn the XML language and familiarize yourself with it. Start by learning a shell scripting language. Apply only procedural programming using your scripting language of choice at first. Use the scripting language you learned to write scripts that perform communications between machines. Make a transfer to a desktop scripting/programming language. Concentrate Take a course on distributed applications design and architectures. Learn about building serviced components and services using your programming language of choice. Learn one or more of the following technologies.

Article: If you were the one who ended the relationship, or if you said hurtful things to your ex, you need to explicitly apologize. Don’t try to skirt around the issues that lead to your breakup. Own up to your mistakes and take responsibility for ways in which you may have wronged or offended your ex. On the other hand, you will also need to forgive your ex for any emotional harm they may have done you. If you reconnect with your ex but still harbor resentment or bitterness, the relationship is bound to fail again. While you and your ex will need to discuss and somehow resolve core issues that lead to your prior breakup, there’s no point in dragging one another through the emotionally painful details. Focus on good things about your ex, and express these in conversation. For example, say things like:   “I was out with friends the other night, and I started thinking about how funny you are and how much I love the way out senses of humor work together.” It may help to take some time to process any stressful events or painful details of the past. Over time, your negative emotions will lose their strength, and you can gain a healthier perspective on the contributions of you and your ex to your relationship’s end. An objective third party, such as a couples therapist, can help you and your ex increase your chances of a successful relationship going forward. A counselor can help you move past difficult issues and communicate more effectively. They can also provide support so you don’t fall back into the same old habits that led to the end of your old relationship. If your ex agrees to rekindle the relationship, start making new memories, going on new dates, and re-forging your emotional connection. It can be tempting to bring old relationship baggage with you when reconciling with an ex, but don’t give in. It can be helpful even to form a couple of new friendships that you and your partner both enjoy. This will help you both get over the breakup by interacting with more people socially.
Question: What is a summary of what this article is about?
Apologize for things you did wrong. Avoid re-hashing painful past details. Seek out couples counseling. Move forward, with your focus on the present.

Q: You will be prompted for a password. Example: sudo apt-get install telnet You will be promoted for that users password. Example: sudo bob telnet localhost 22 You will be promoted for a password. Type logout to switch back. You will be promoted for their password. Type logout to switch back.
A:
Type sudo before a command to execute the command as the root user. Type sudo <username> before a command to execute the command as another user on the system. Type su to switch your command line session to the root user. Type su <username> to switch your command line session to another user.
