What is DDS?

The Object Management Group, the same folks who gave us UML, CORBA, and SysML, created DDS (Data Distribution Service) as a standard for interoperable middleware. DDS is designed to be used for both high level systems integration, like ROS, and real-time applications on embedded devices. It is architecture-independent, scalable, asynchronous, and uses a publish-subscribe communication pattern.

It can be implemented in several languages using a thin, language idiomatic C API. The XML and IDL specifications are also language agnostic. This allows the DDS application, including Domain Participants and data samples, to be defined in a programming language of choice without requiring a common software interface. This approach has led to a wide variety of low-level implementations, but DDS applications are still interoperable because they are defined in a common specification.

Another feature of DDS is that it provides control over the reliability of data transfer. This can be tuned to be essentially TCP for soft real-time applications or made more robust with guaranteed latency and dropout tolerance.

DDS has a history of being used in aerospace and defense, which may explain its more closed ethos. It is also relatively old and has a very different community to that of modern projects like ZeroMQ. However, the LGPL options from RTI and OpenSplice are encouraging, and research into ros_dds has shown that a feature-complete, DDS-specification compatible C API can be wrapped in other languages with reasonable effort.

Foods For a Bigger ButtFoods For a Bigger Butt

It is a fact that you can build bigger muscles in your glutes with exercise and the right nutrition. However, you do not get foods for a bigger butt from eating more food. The muscle building comes from training, the nutrition feeds the muscles and the proper rest is key to recovery. The foods that are best for a bigger butt are protein-rich, high in carbohydrates and include healthy fats.

How to Identify and Safely Dispose of Expired Protein Shakes

Quinoa is a great source of complex carbs and contains eight grams of protein in one cup. It provides the body with all the essential amino acids it does not produce naturally. The carbohydrates in quinoa will fuel your muscles during resistance workouts and reduce the onset of muscle damage and glycogen depletion.

Eggs are a great source of protein and the amino acid leucine. Leucine is an essential amino acid and helps to stimulate muscle growth in your glutes. Eggs are also rich in vitamin B6, choline, lutein and zeaxanthin.

Another protein-rich food is chicken. It is a good source of vitamins and minerals, including potassium and zinc. Zinc promotes muscle growth and recovery, while the potassium in chicken balances blood pressure and regulates blood sugar levels.

Other proteins that are helpful for a bigger butt are turkey, fish and poultry. Fish is high in omega-3 fatty acids, which are beneficial for muscle growth and reduce bodily inflammation and stress. Poultry is another good protein source, particularly dark meat, which is rich in iron.
