A Brief History of Parallel Programming in Java

Concurrent programming was part of the initial Java specification, although most of the 1.x JDKs available at that time only supported concurrency at the JVM level (using so called green threads) without being able to fully benefit from the multi-core hardware. The Java language already contained the basic primitives (Thread class, wait() and notify() function calls, and the ‘synchronized’ keyword) that are still used nowdays to program modern many-core and multi-core hardware architectures.

Then progressively the JVMs evolved in order to improve mapping of to native threads (beter I/Os, faster context switching). .

As part of JSR 166, Java 5 introduced the java.util.concurrent package, which provides concurrency utilities (concurrent collections, atomic variables, locks) to ease development of concurrent programs and increase maintainability. On the performance front, the newly provided execution framework introduce a pool of reusable worker threads in order to reduce the cost of creating new (native) threads.

The next release, Java 6.0 received a small update as part of JSR 166x: mostly bug fixing and polishing, but also a few new APIs like ConcurrentSkipListMap and ConcurrentSkipSetMap.

Java 7.0, scheduled for mid 2011, will bring some new tools for parallel programming (JSR 166y), a fine-grained concurrent computation framework, some new concurrent data-structures and a new concurrent random number generator (ThreadLocalRandom). The new concurrency framework is based on the fork/join metaphor and can be used for algorithms that can be expressed using divide-and-conquer techniques. Then the work-stealing policy implemented in the framework will ensure that all the concurrent tasks are dispatched efficiently to all available threads (and thus to all available processor cores). It is also worth noticing that some other areas of the JVM are also following this trend (see for example the new thread-safe concurrent class loaders).

Some other features previously scheduled for Java 7.0 were postponed to Java 8.0 after the acquisition of Sun by Oracle (this late split is known as ‘Plan B’) and JSR 166z is supposed to cover these new enhancements. One of the main feature would be the introduction of lambda-like expressions (previously known as Project Lambda and described in JSR 335) and their use in combination with the new ParallelArray framework which provides an integration of data parallelism into the Java language.

Avoiding Downtime Via Computer Support

One of the things that operations managers would loathe is downtime. A downtime in business can be defined as a situation wherein operations could not continue. One of the leading causes of business downtime is the failure of equipment, specifically computer equipment. For example, if your offices email servers would go down then interoffice communication would usually cease. Even simpler, printer malfunction could lead to downtime as you wait for the paper jams to clear up.

Thus, businesses are often in the lookout for methods to be able to curb the downtime. A way that they would be able to do that is by contacting a Computer support firm. Computer support firms can help you solve this issue through a variety of ways such as:

24/7 support:

More often than not, breakdowns happen in times when people are not actively monitoring the situation. This would occur late into the shift and would often cause troubles the next day. If you have contacted a computer support firm to provide you with round the clock service, then you would not have to wait until the next day to detect or even fix the problems.
They could easily monitor your systems even if your own staff is not actively checking or guarding them. This would lead to a quicker response time than having to do next day fixes, avoiding he lengthy down times that managers hate.

Expert assessment:

Another common cause for downtime is the assessment and investigation that occurs whenever an issue is found. Usually operation is stopped as the IT experts would have to do a thorough checking on how the problem came up.

By contacting a computer support firm, you would be able to bank on their expert knowledge of handling the various computer systems. This means that investigation and assessment time is narrowed down as they would already have prior experience in solving various computer issues.
The help of the computer support team streamlines the time needed to be able to provide a solution for your computer problems.

Quick access to parts:

Lastly, a computer support company would have a much wider network from which to access replacement parts and accessories for your busted equipment. Usually, in house purchasing would have to go to a single supplier and hope that they have the parts that are needed for the fixes.
A computer support partner would have more options as they would usually have more connections.

Hardware MIDI Sequencer Making music easier

MIDI stands for Musical Instrument Digital Interface, and these MIDI Sequencers have become vastly popular among many musicians, professional and those who just do it as a hobby, because it makes music so much easier, especially if you don’t have a full band to back you up. Even if you are trained to play multiple instruments, typically, you won’t be playing them all at once, and having a full band to back you up is ideal. This is difficult for many people though, especially those who don’t make a living by being in a band, many people who are even in a band have scheduling issues, creative control struggles, and a variety of other issues that can often make the band either dissolve or their practices few and far between. With a hardware midi sequencer, you are able to simulate the parts of the band that might not be present via electronic instruments. Having an electronic band can help you practice and make your music more intricate and complex than it would be with simply one instrument. A hardware midi sequencer can do more than just mimic instruments electronically as well, it can read what you are playing, and break down audio into tones and musical notes, as well as manipulate or amplify sounds giving you total control over the way the music sounds when it is recorded and produced, or even as it is being played. Keyboard sequencers are another form of MIDI hardware and they can help adjust the audio of your music and perfectly hone the sound of the many electronic instruments you’ll have access to when utilizing this kind of hardware audio generation. As the years have gone on, MIDI technologies have enhanced and progressed greatly, and now multiple musical instruments can all be generated and augmented with a common sequencer. Then this sequencer can transmit the amplified data, with all the electronic instruments to the synthesizer. Postproduction audio software also allows you to manipulate your music even more. Keyboard sequencers are an easy and intuitive way to manipulate the audio of your music before it is sent to the synthesizer. If you purchase a MIDI controller, a hardware midi sequencer, and a midi synthesizer, you will be able to use them hand in hand to create an entire virtual band to play along to your music, as well as adjust their sounds on the fly and in post-production. You will also have the options to manipulate the sound of your own instrument through these devices and make creating professional sounding music easier than ever. Hardware midi sequencers are more advanced and common place today than ever before. They have provided a way for many artists, no matter how popular or at what level, to record and produce their music easier and quicker.

How is 3D printing technology used in Architecture and Medicine

D printing technology is used to manufacture prototypes, tools, and end-user parts directly from a CAD design. This printing technology offers unprecedented flexibility as it can create a part of any dimension out of any material. Some of the used include metals, polymers, ceramics, composites, and many more. The 3D printing technology has complete control over material composition, surface texture, and micro-structure of the prototype. 3D printing technology also allows the user to construct prototypes using two different materials. >

Lets take a look at this amazing technology and how it has affected the field of architecture and medicine:

3D printing for Architecture

Architects know that there is nothing like a physical model of a building when it comes to displaying their work or design concept. Physical models also play an important role when it comes to explaining and convincing the customer while selling a project.

3D printers are affordable and high quality solutions for architects. Building a physical model requires great deal of expertise, precision, and time. help designers focus on their building design, while the devices make 3D models of the project.

Many architects are not tech-savvy and are not used to operating complex devices. 3D printers do not require human intervention at any stage of the printing process. Architects just need to need to draw a CAD diagram of the project and instruct the 3D printer to build a 3D model. The 3D printer can print the model within a few hours, which can then be presented to the client.

3D printers are capable of producing of 3D models with accuracy and speed without compromising on the finer details of the architectural project. The price of desktop 3D printing machines is not that high and independent architects can also afford them.

3D printing for Medicine

The application of can also be found in the production of medical devices. There are different 3D printing materials available that can be used to build real parts. For example, manufacturing hearing aids is a complex process because they are custom-fit devices and cannot be mass produced. 3D printing greatly helps in such matters where medical devices need to custom-fit a patient.

The future of the 3D printing technology is very bright. Market experts state that 3D printing technology will be affordable to the masses by the next decade. The prices of 3D printing devices are falling rapidly, and it is believed that the prices of 3D printers will drop by as much as 80% in the next 5-10 years. It will not be a surprise to see 3D printing devices in each household just like refrigerators, washing machines, and televisions.
