Mark where you will drill in both with a permanent marker. The spots you mark are the areas you plan to concrete the concrete and wood with the hammer-set concrete fasteners. This will keep your drill holes precise so your fasteners will fit securely into the wood and concrete. You will need hammer-set concrete fasteners to connect the wood and concrete, which you can get online or from most home improvement stores. Drill a hole into the concrete approximately 14 inch (0.64cm) deeper than your concrete fastener. When you're finished drilling, blow any remaining concrete dust out of the hole with a small vacuum. Take all necessary safety precautions while using a drill, and put on safety goggles and professional-grade earmuffs beforehand. In a pinch, you can also use a syringe blower to remove the dust. Using your screw markings as guides, align the wood with the concrete object and drill through the wood into the drilled concrete hole. This will help you make sure that the holes are aligned. Unlike the concrete, where you only have to drill 14 inch (0.64cm) deeper than the fastener's length, you should drill completely through the wood. Keeping the wood and concrete holes aligned, position the fastener into the hole and hammer it through. After driving it through the hole, the concrete fastener should expand at the back and wedge itself tightly into the concrete.

Using a screw extractor involves drilling into metal. The last thing you want is a flying shard of metal in your eye. Wear safety goggles made with polycarbonate lenses. A center punch is a metal cylinder that looks like a pen. You can find them at any hardware store. With one hand, hold the metal tip against the center of the screw head. Pick up a hammer in your free hand and use it to tap the top of the punch. Strike it very lightly. If you did it right, you'll see a small divot in the screw. This guides your drill bit into the center of the screw. If the screw is in a tight space, use a small metal drill bit and a right angle drill. Be careful that the bit doesn't slip while you're drilling. Thread cutting oil is sold in big jugs at hardware stores, but you only need a drop. Tip the bottle over to splash a little bit onto the screw head. Cutting oil lubricates the metal, which means less time spent drilling and less wear and tear for your drill bit. If you don't have this oil, you can try a drop of motor oil, WD-40, or another lubricant. Household oils will help but offer less protection to the drill bit. Penetrating oil is needed for rusted screws or ones attached to metal surfaces. It loosens the screw, making it easier to remove. Add a drop of it onto the screw head on top of the thread cutting oil. If you don't have penetrating oil, acetone may work too.

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.
