Some African-Americans use their hair as means to connect with their roots while others see it as a fashion statement to be changed with the times. In the black community, hairstyles and views about hair care methods vary greatly; from braiding to locking, Afros, wigs for sale and weaves, African-American hairstyles are very diverse.The most popular natural hairstyles for African Americans is the Afro, dreadlocks and braiding. If you have chemically processed hair, it is important to consult with your stylist before attempting to go natural. Your stylist may be able to treat your hair with a soft processing treatment as well as shampooing and conditioning in order to keep it from breaking as you grow it out naturally.

When transitioning into natural you hair, you might want to use a wig or synthetic wigs braids to hide growth. Once your hair is the length you wish to have it, you can achieve the Afro look by trimming the hair evenly all around. Then, use a hair pick to comb out and add volume to hair.When you are purchasing an African American wig, you must be familiar with its care and maintenance. Improper cleaning technique can cause deterioration of it quickly. It is always advised, that it should be washed after wearing it for eight to ten times. But frequent cleaning is required if you stay in a humid place or in a region where lot of smoke is produced. Drip drying is the best of drying that should be followed.

Never squeeze it to drain water as it can ruin its shape and style. After several washing if you find that it has become a little hard then use conditioning spray to add softness to it.Use african american wigs brush to brush through your wig.Be sure to use a wig shampoo. It is important that you do not use regular shampoo, it can damage your wig.Fill up a sink with cold or lukewarm water and add the wig shampoo (generally about a tablespoon... read the shampoo bottle for precise directions).Place your wig in the water and gently swish it around - be gentle! Do this for about a minute.Rinse your wig in cold running water until thoroughly rinsed.

Hallo Herr Salomon,


wir haben eine Frage zu unserem Projekt:


Wir senden mit unserem Programm eine UDP Message und erwarten eine Antwort. Wir bekommen dann aber einen Timeout-Fehler (ERR 56), da wir keine Datenpaket erhalten.


Liegt der Fehler in unserem Programmcode oder müssen wir für die UDP Kommunikation irgendwelche Einstellungen in LabVIEW vornehmen? Das Internet gibt hierrauf keine hilfreichen Antworten.

Dear readers,


there have been some questions on how to create a Visual Studio project from the source files (.cpp) that are attached to some of the posts on this blog. This makes it possible to modify the code to your preferences.

The post will hopefully act as a tutorial in order to successfully create a project using either OpenCV or PCL functionalities. You can setup the project manually of course, but I prefer using Cmake (open-source). This helps you configure all dependencies and libraries with a couple of mouse clicks. You can get it from here:


After installing Cmake, follow the instructions below:


1. create a new folder (I will call it "project folder") and put the source code (.cpp) inside it. Create another folder inside the previously created folder and name it "build".

2. create a file named "CMakeLists.txt", put it in the "project folder" and setup the Cmake variables in the .txt as follows (replacing the bold text with your values):


     2a. using OpenCV


               cmake_minimum_required(VERSION 2.6)

               project(project name)

               find_package(OpenCV REQUIRED)

               add_executable(name source_file.cpp)

               target_link_libraries(name ${OpenCV_LIBS} )


     2b. using PCL


               cmake_minimum_required(VERSION 2.6 FATAL_ERROR)

               project(project name)

               find_package(PCL 1.3 REQUIRED)




               add_executable(name source_file.cpp)

               target_link_libraries (name ${PCL_LIBRARIES})


3. open Cmake and add path to source code (...\"project folder"). Add also the path to the "build" folder.


4. select "Configure" and specify the generator for the project (I use Visual Studio 2010). Use default native compilers. Click finish.


     4a. if OpenCV configuration is giving errors, complaining that OpenCV directory is not found, manually add it. Select "ungrouped entries" and specify the OpenCV dir "...\opencv\build". Click "Configure" again.


5. click on "Generate".


6. the "build" is now populated with the Cmake output. Open the Visual Studio solution.


7. in "Solution Explorer", right click on your project and select "Properties". Under "General" change "Target Extension" to .dll and change "Configuration Type" to "Dynamic Library (.dll)".


8. Apply changes and build solution. I suggest using "Release" configuration for optimized performance. Remember you need to do step 7 for the "Release" configuration also.


Hope this will be useful to people having troubles with building from source code.


Best regards,



As most regular readers will know my prime interest is software design and specifically why a design becomes complex. Since becoming a CLA I have had quite a lot of my fellow CLAs stipulate how important SMORES is when judging a good design.


In the interest of foolishness I going to state now that I don't get it!


So the question I throw back is this.

Is SMORES the only tool you use to judge a good design?


First I guess I should describe SMORES









I'm going to do my due diligence now and explain each one in turn. Most of this has been stolen from here.


For something to be scalable, it must work the same without modification regardless of how much throughput the system has to manage.  In software, scalable software can handle one or many users, one or many channels of data, one or many reports, etc.


If you use SubVIs you are making modular code, if these modules are designed with some regard to coupling, cohesion and information hiding your code will more pleasant than if you don't.


Software, processes, and systems should be reviewed and streamlined to ensure the best possible output has been achieved. 


To make something "reusable" refers to the extra investment required to take anything originally designed for a specific purpose and add the input and output definitions and refinements to make the same object attractive for use on another purpose.


Extensible refers to the ability to connect new functionality onto an existing system without having to rearchitect whatever you are connecting on to.  A good example of this is a plug-in architecture.


Simplified doesn't always mean the object can or should be "simple".  It means that there is value to be had in making the object you are building as simple as possible without sacrificing scalability, extensibility, etc.


I have several issues with these as design considerations in my problem domain, I'll tackle the easy ones first...


Optimized and Simplified - now these seem a little wishy-washy and hard to measure to my engineering brain, who defines simplified for example. As we have seen from our design discussions here simple for me is not necessarily simple for someone else (more likely the other way round in my experience), so how do we judge it?. Similarly at what point are we happy that a system has been optimized to our satisfaction.


Modular - I've whittered on about modular design a lot here and it is kind of an assumption that if you don't use SubVIs you probably shouldn't be worrying about SORES (see what I did there)


Scalable - We've had several interesting conversations about this and my position is this, we write configurable software, this gives us a certain amount scalability. I would also add that LabVIEW is a high level language (definitely 4GL), some might even call it a Rapid Application Development environment. Should we really be applying this amount of importance to scalability for a language so high level?


Extensible - I think the following quote from an excellent article by avilay sums up a lot of the point I'm trying to make.

“but suppose that tomorrow somebody wants to add X here…”. Be wary of this design principle. Be very wary. Unless “tomorrow” is a real date in the future, and “somebody” is a real person, this design principle can lead you down a deep rabbit hole with nothing but dirt at the bottom.


Re-use - I like re-use, really I do. But I suspect a lot of time is spent polishing code for re-use and it gets stuck away and never touched. There is some very interesting and honest work done on re-use that concludes that the payback of planned re-use is not quite what you would expect.


Arnoud de Kuijper - Test and Measurement Solutions did an excellent presentation at the European CLA Summit, in it he introduced SMURF

A version is linked here





I prefer this mainly because I love the little blue fellas. Also Flexible is very very important to me and Unique is actually a grown up way of describing what we do. We have a couple of standard templates but quite a lot of what we do is unique from system to system.


Now I would like to add a few more to the list.


I can't believe Functional and Robust are not on the list. Readable, Debuggable and Maintainable are extremely important design considerations too. Measurable is also an increasingly important design consideration, especially in RT or control systems. As mentioned earlier Configurable as a sub-set of scalable is a very important design criteria for us.


Now how do our customers mark our software if they have to allocate points and how does this compare to our own marks?

James Shore writes about good and great software design in an article titled Quality with a Name. From the article:


A good software design minimizes the time required to create, modify, and maintain the software while achieving acceptable run-time performance.


Also these requirements don't always play nice together, many of the techniques for extensibility seriously affect readability and so it goes on.


So am I dismissing SMORES out of hand?

I think SMORES is useful if you are designing APIs and toolkits, I think it is less useful for projects.

So perhaps we need acronyms for each type of use case.




Perhaps we should not use acronyms blindly.


Lots of Love

The U.S. Department of Energy is counting on wind power to meet 20% of the nation’s power needs by 2030, up from 3% today. This feat will only be possible if the leading academic and industry experts advance technologies needed to develop offshore wind power, and NI is playing a central role in this collaboration.


Last November, Clemson University unveiled the world’s largest 15-megawatt Wind Turbine Drivetrain Test facility, intended to create new technologies for the energy market. They selected NI LabVIEW and  NI PXI modular hardware for a majority of measurement types. 




The facility has expanded to include a grid simulation lab that allows manufacturers to test both the mechanical and electrical characteristics of their machines in a controlled and calibrated environment. It uses LabVIEW and NI Multisim software, as well as NI PXI, NI R Series, NI FlexRIO, and NI CompactRIO hardware.


With this new and innovative testing center, companies can test a hardware prototype for any energy resource on a utility scale (up to 15 MW, which is HUGE) and gauge the impact of adding this technology to the actual grid before deploying it. This blows away any other wind turbine test facility in the world!
