GoPro Hero4 Black Review: The Best Action Cam Gets Upgraded

The main difference between a normal camera and an action camera lies in its form factor. The action camera can be placed on a surfboard out on huge waves, strapped onto dogs, ceiling fans and flying drones without the risk of damage. In fact, they are made for such purposes, where the use of a normal camera will be bizarre and impractical.

The GoPro is a tiny box like action camera with an amazing picture quality and other features added by GoPro and other third party companies. There are two models: the GoPro Hero4 Black and the GoPro Hero4 Silver. There are subtle differences between the two. The Silver costs a 100 dollars less than the Black, as the Black one has additional features and a faster processor. It has the best video quality and more shooting options, as it supports a wide range of mounting options.

The History

This series of action camera has been in existence since the year 2004. The GoPro Hero range of action camera has been the capture of adventure sports since that time. Initially the photographs used to be captured on still shots on 35mm film. GoPro can be called a pioneer of sorts of the action camera. The years hence has only resulted in advancement of the original idea.

The Exterior

The main aspect of the exterior of action camera is that it should be inconspicuous. Therefore the core design and the ergonomics haven’t seen much change throughout the years. Its dimensions can be measured as 41X59X30mm. The camera weighs 88g with the exclusion of its waterproof cover. After the cover is added on, it weighs around 152g.

A small LCD is located at its left side and the lens protrude from the front. Next to the LCD, there are two LED indicators- the top one blinks blue to indicate the WiFi signal and lower one shows the camera status and also works as the battery indicator. The power up button is located beneath the LCD and it also can change the modes.

There is another camera status indicator located on the rear of the action camera and a port, for the purpose of accessorizing the camera with an external LCD monitor and LCD Touch BacPac.

The right side plays host to the Micro-HDMI port, Micro-USB Port as well as the MicroSD card slot and a speaker. The battery door is at the bottom, a tiny slip of paper which is attached to the battery to pull it out.

The Interior

This action camera is equipped with a 12 megapixel 1/2.3 inch CMOS sensor as well as an F2.8 aperture ultra wide angle lens. It can capture 4K (3840X2160) footage at 30fps and also shoot 1080p video at up to 120fps and 720p footage at 240fps. It has a mono microphone for the purpose of recording audios, plus there is a provision of an optional 3.5mm input accessory for a better external mike if required. For recording better audios, there is an added integrated analog-to-digital converter present.

Producing Valuable Content: How to Get Stared

Every SEO expert will tell you that the key to a successful SEO campaign is valuable content. What they often forget to mention is the very definition of valuable content and how we can make them. Producing valuable content doesn’t have to be difficult as long as you know the basic guidelines to follow. To help you get started, we are going to discuss some useful tips on how to produce valuable content in this article.
Useful and Informative

The two aspects to consider when writing contents for your site are usefulness and the information you are adding to the contents. First of all, the article needs to offer some use to the visitors. A good way of making sure your site’s contents are useful is by placing yourself as a visitor and asking these questions:

• Did I get tips and tricks from the article?
• Is the article amusing?
• Can I do something new with the information I get from the article?

Aside from being useful, an article should also be informative. News, updates and other contents that fall in the same category may not always be useful, but they can always be informative.

Concise and Readable

Here’s another set of aspects to keep in mind when developing valuable contents. Long articles are not always good, especially if most of the actual contents are not useful or informative enough to your users. Keep it short and concise to maximize the value of the content itself.

I’m not saying you can’t write long articles; as a matter of fact, you can. However, long articles need to be kept readable for them to be as valuable to users as shorter, more compact articles with a lot of information. To help make long articles more readable:

• Divide the article into paragraphs and state what the paragraph is all about in the first sentence. Most of your users will scan through paragraphs quickly, so mentioning your point at the beginning of the paragraphs really helps.
• Furthermore, divide the long article into parts with subtitles and pointers. An article that has subtitles are much easier to scan and are often more readable than those that only include long paragraphs.
• Use images and visual elements to keep users engaged. Reading long articles online can be quite boring, so visual cues are needed to keep users glued to the screen. It will also make your site more appealing.

Credibility Matters! 

Writing an article for the web is not like writing an article for magazines or papers. Site owners tend to ‘forget’ about citing their sources and providing valid data. This will greatly damage the article’s credibility; of course, it will also damage the site’s credibility.

When you do present data from other sources, site the sources properly. Your users will automatically associate citations with better credibility, causing them to trust the contents you are displaying even more. According to SEO experts from Blue Hat Marketing, using inner-linking to cite other pages on your site is also a great for getting your site’s SEO performance up.

Build A Mars Base with A Box of Engineered Bugs

Travel to Alien Planet – Bug Boxes – Engineered Microbes

The next time humans intend to set foot on an alien planet, they may not have to travel alone but travel along with small lightweight `bug boxes’ that could be full of engineered microbes that would make life on these planets much more liveable.

The pioneering settlers would be needing food, fuel as well as shelter in order to survive on a distant world and tugging along bulky supplies from the Earth could be costly. Another option has been offered by Synthetic biology.

It is said that microbes weigh less and the space taken is next to nothing on a spacecraft though once the mission lands on Mars it is said that they could multiply by feeding on the materials that may be available there. The outcome of their labour could provide the essentials for human settlement.

A research has begun by NASA to realise this vision, according to Lynn Rothschild at the Ames Research Centre in Moffett Field, California. Rothschild who is the leader of NASA’s new Synthetic Biology Initiative, aims to build designer microbes for future crewed space missions and shared her vision at the BioDesign Forum, last week in Cambridge, UK.

Synthetic Biology – At Crossroads of Biology/Engineering 

Synthetics biology lying at the crossroads of biology and engineering has its practitioners building a biological toolkit comprising of chunks of genes, known as biobricks, each performing a certain function of making a bacterium generate natural antifreeze molecule, for instance: Biobricks could be inserted into other microbes to provide that function.

With this approach, a microbe having the capabilities of surviving on an alien planet could become one that can endure human life there. With regards to energy, several earthly microbes would have died in extra-terrestrial environment that are rich in carbon dioxide and nitrogen, the two main elements of Martian air. Anabaena, an ancient cyanobacterium tends to thrive in these conditions though metabolising both gases in order to make sugar.

Rothschild states that `as long as it has warmth and some shielding from ultraviolet light radiation, it could do well on gases in the mars atmosphere’. Anabaena utilises most of the energy produced, from carbon dioxide and nitrogen but synthetic biologist could encourage the cyanobacteria to share its supplies.

Waste – Feed the Microbes

At a synthetic biology competition last year – International Genetically Engineered Machines – iGEM, a team from Brown University in Providence, Rhode Island and Stanford University in California portrayed how inserting genetic machinery from E.coli made Anabaena excrete more of its energy as sugar.

 Moreover they also showed that they tend to support colonies of other bacteria as well on sugar. Such microbial colonies, in theory tend to make oil, plastic or fuel for the astronauts. The team which was led by Andre Burnier, a recent Brown graduate who had been advised by Rothschild had also come with options of supplying human settlers on Mars with mortar and bricks and had started with a bacterium known as Sporosarcina pasteurii that unusually tends to break down urea which is the main waste product in urine, excreting ammonium, making the local atmosphere alkaline enough for calcium carbonate cement to form. The waste created by the astronauts could feed the microbes and they in turn could help strengthen fine rocky material on the planet’s surface to create bricks.

Logitech Bluetooth Adapter : Gadget Review

Logitech Bluetooth Adapter Offers Simplicity Backed By Performance

In the world of gadgets Smartphones are the most talked and bought gadgets which are ruling the world right now. Still there are companies which are making huge sum by providing such gadgets which are necessary yet a buyer doesn’t know it. Logitech, JBL and other have invested a lot in creating high end Bluetooth speakers which offers impressive sound.

Usually the better sounding Bluetooth speakers are expensive and find very few takers. Most of the people are still using the 2.1 or 5.1 channel speaker system which offers perfect sound. Logitech is all set to bridge this gap of reliance of the old technology with its Bluetooth adapter which can easily turn any speaker system into a wireless system.

Logitech Brings Elegant and Compact Design

For a Bluetooth adapter it is size which matters and Logitech has craftily designed an ultra compact and handy adapter. Logitech Bluetooth Adapter measures just 50x50x23mm which can easily fit within the palm and it can easily kept hidden away from the view.

Tough plastic has been used to make it highly durable. This Bluetooth adapter supports Bluetooth v3.0 which a range of 15m and make sure that the connected devices are within the line of sight. A single button for Bluetooth had been placed at the top for pairing with other devices. The rear side of the adapter has 3.5mm and RCA outputs and a power socket. Furthermore a relatively small blue LED light is on the bottom side which blinks at the moment of pairing and remains constant once paired.

Logitech Bluetooth Adapter Brings Splendid Performance

In order to staring pairing process long pressing on Bluetooth button is required. Adapter requires to get paired for the first time only after which it connects automatically. It works splendidly across a wide range of devices like the home theatre system; Bluetooth enabled music players, Apple products like Macbook Air, iPhone and other smartphones.

Furthermore this adapter also gives the freedom of pairing with two different devices at the same time as audio source and users can actively switch between them. Once the connection is established the adapter simply converts the Bluetooth wireless data into analog signals which are transmitted to the connected speakers.

Whether you play music in the device or through speakers connected by the adapter the quality is almost same except for little which can only be picked when listened very closely. The Bluetooth connection remains firm when the connected device is placed in the clear line of sight while being away certain anomalies appear. Hence it will be wise to keep the devices in sight in order to enjoy music.

Give A New Life To Old Speakers With Bluetooth Adapter

The Logitech Bluetooth adapter was initially launched at the price of Rs. 1,999 but in the online sphere it can be easily bought at just Rs. 1,200. Now price shouldn’t be a concern for the enthusiastic individual who is looking for an alternative to enhance the capability of their age-old music systems.

Leaked Details, If True, Point To Potent AMD Zen CPU

It has been more than a year that the potential new about the next-generation CPU architecture from AMD, and it has been code named which known as Zen however it is running in the fantasy of the fans of the company as well as among the people who are looking for more efficient competitor when compared to Intel. The technical configuration can differ, but all geeks should be ready to see the next generation chip full of wallop. The leaked slide is only a part of the highest-end part.

Even though the slide has manage to capture more than required focus, details of the chip might have drastic changes in terms of what it appears now and how it will be at the time of the launch. For instance, the leaked slide itself might not be accurate.

Reports from Fudzilla indicates that this new CPU will be able to offer nearly 16 Zen cores, in which each of the core will be further supporting 2 threads out of the total 32 threads. Rumors also suggest that this new core will be using Simultaneous Multithreading, which is completely opposite to the Clustered Multi-Threading on which the AMD has debuted as part of the Bulldozer family and has been in use for the past 4 years.

Every core has been backed up by 512K of L2 cache and with 32MB of L3 cache will be seen throughout the entire core. This clearly depicts that the L3 structure has been inspired from the Bulldozer. If AMD will be come over from the cache there might be a improvement in the performance. The new integrated GPU will also be offering double-precision floating point at every 1/2 single-precision speed.

Is it too good to be believed? 

The CPU layout shown in the leaked slide makes a lot of sense to everyone. People can clearly see at the modular part and AMD part wherein the Zen module consists 8 threads and 2MB of L2, some unbelievable L3 cache as well as of 4 CPU cores,. Nevertheless, what has been able to raise eyebrows among all the fans includes 64 lanes of PCIe 3.0, HBM interface, and quad-channel DDR4.

The reason being, the highest end servers from Intel pack comes with 32 PCI-Express lanes and even though the Quad-channel DDR4 is available, Intel can only support 4x DDR4-2133. You have to believe that HBM has arrived and the day is not far when it will integrate with servers and desktops since 16GB of HBM memory makes a whole lot of difference. However the Zen’s 512GBs memory interface is one of the most important achievements. This CPU is expected to be unveiled in another 12 to 18 months in the world of server.

AMD will be able to create history if they are able to meet the power consumption and IPC targets. Still the details have not yet been confirmed. It is expected that in coming days it will be big if company will be able to launch the device with 64 lanes of PCI-Express, a totally revamped CPU, integrated graphics processor and 16GB of HBM memory.
