Google maps replace its planisphere with a terrestrial globe.

google earth

Last week, Google updated the desktop version of its online mapping service by replacing the planisphere system with a globe.

With all due respect to flat earth supporters, such as Kyrie Irving from the Boston Celtics, last weekend’s Google maps update gave a much more spherical shape to its virtual planet Earth by offering a world’s planisphere matching the famous Mercator’s projection.

If this modification does not seem to bring any modification within the framework of the traditional use of Google Maps, it is by zooming out that the magic of the cartography service works by proposing not anymore a flat world map, but well a terrestrial globe in 3D.

A desire to represent the earth more realistically.

If Google chose to abandon the planisphere, it is because the giant of Mountain View wishes to propose a vision of the earth much more realistic than the planisphere of the world allows according to the Mercator projection.

Imposed as the standard planisphere in the world thanks to the precision it could bring during sea voyages, Mercator’s projection has the main flaw of enormously distorting the areas that are furthest from the equator, by presenting Europe, for example, as more extensive on earth than South America, when in reality it is almost twice as large as Europe.

To overcome this problem, Google has opted for a representation of the earth in the form of a globe, which provides a representation of the world much more realistic than a planisphere allows.

Google Maps conquering space

However, the introduction of the globe is not the only novelty that the Mountain View giant has brought to its mapping service. By activating the satellite mode, it is now possible to travel in space.

With this update, Google has doubled its efforts by giving its users the possibility to observe live which surface of the earth and planets are illuminated by the sun, the effects of lighting on the earth from space or the possibility to visit other planets or natural satellites.

First iPhone X Plus and iPhone 9 photos unveiled

Today is a big day as it seems that the first pictures of iPhone X Plus and iPhone 9 have just been leaked. We’re letting you know right away as we know there are quite a few fan boys in our audience 😉

We already had a small idea of the look of the iPhone model 2018, especially with some of the few realistic designs of the iPhone X leaked, but a few hours ago, things have been confirmed, through the leak of several photos concerning the brand’s very high-end new iPhone X Plus phone.

This phone will benefit from a 6.5-inch OLED screen, as well as the iPhone 9, which will be the entry level model. This smartphone should integrate this time a 6.1-inch LCD panel. The two phones appeared on Twitter, via the account of the leaker Ben Geskin, which revealed some photos, explaining nevertheless that they were dummy models, intended for the manufacturers of hulls or accessories, so that they can take advantage on the manufacture of their products.

Dummy models were leaked, but which allow knowing a little more about the design of the two new iPhone, and in particular to confirm the presence of a double photo sensor on the iPhone X Plus.

However, we do not know if these new Apple products will be able to charge each other. Up to now, we had mostly been given computer-generated images, but it has to be said that if this new leak proves to be true, the rumours previously revealed were finally quite close to the truth. To have an official confirmation, and hope for answers to all our questions, we will probably have to wait for the keynote of September 2018.

As usual, let’s wait and SEE people !

What are your main expectations regarding this new flagship model?

The Galaxy Watch, a Samsung connected watch?

Is this a complete change of direction for Samsung in the connected watch market? The South Korean company already has a range called Gear, but one cannot say that it is a great success. More and more indications tend to prove that the company would take a new course with a range of Galaxy Watch.

Farewell Gear?

According to the SamMobile portal, Samsung is about to make a significant strategic change. To support this statement, the site relies on a “Samsung Galaxy Watch” logo. A generally well-informed Twitter user goes even further and claims that Samsung would give up his home operating system Tizen in the process. Instead, it would return to WearOS, the system developed by Google, a complete change of direction. According to some rumors, Samsung would also integrate his vocal assistant Bixby.

Reviving a dying market

As for Samsung, no confirmation for the moment and it will probably be necessary to wait at least the end of August to know more about it. A period generally is chosen by Samsung to unveil its new watch models connected during the IFA.

Information which in any case should globally confirm that there is no big revolution to predict. Samsung is probably looking to combine its different products under the Galaxy banner. A label that should be a little more meaningful and more attractive to customers than Gear.

Something to take Samsung out of the niche market and finally compete with Apple, the primary player in the market? If the Swiss giants, specialists in watchmaking, are unable to do so, the task still looks complicated. We’ll have to wait a bit to find out…

Browser: Chrome, Edge, Firefox… Is there a better browser?

browser_wars

We often hear fans of a browser defend it, arguing that it is better than the competition, whether it be Chrome, Edge or Firefox. The question we are therefore entitled to ask ourselves is: which is the best web browser between these three alternatives? Chrome, Firefox or Edge?

Like many, you used a web browser for a while before getting angry at it. Then you tried the competitors and finally choose another one. So finally, which is the best web browser to surf the web serenely and efficiently?

What is the best web browser between Chrome, Firefox, and Edge?

The easiest way to get a more or less precise idea is to submit them to a series of different benchmarks and rank them according to the results.

which browser do your preferHere are 5 benchmarks we selected to see which browser is better:

• HTML5Test, to check efficiency with HTML5 language
• JetStream, to check JavaScript support
• Kraken, also for a little test on the issue of JavaScript
• MotionMark, which studies graphics performance
• Speedometer to get an idea of the overall performance

What came out of these different benchmark tests?

• HTML5Test: Chrome is first before Firefox, then Edge
• Jetstream: Edge ahead of Firefox and Chrome in the third position
• Kraken: Firefox passes Edge and Chrome on the third step
• MotionMark: Edge takes a considerable lead over Firefox and Chrome which show equivalent results
• Speedometer: Chrome crushes by far Firefox and Edge

Note: it is essential to specify with which configuration this series of Benchmarks was carried out because apparently with another model the results could evolve in one direction or another… It is also important to specify which version of the browser was used in each case.

The configuration:

The five benchmarks were run on an Intel Core-i5 laptop, supported by 256GB SSD and 8GB RAM, all under Windows 10 (64-bit).

In conclusion, as you will have noticed all alone, there is not a big winner concerning the Internet navigation and the three browsers are globally equal. We can slightly give an advance to Chrome this time, but remember that in 2015, the same test gave Edge the winner. The tests depend mainly on the optimizations that each publisher performs in its new versions before the competition aligns itself…

And you, which browser do you use every day and why?

The blockchain revolution : how does it work ?

blockchain tech

The blockchain is often associated with Bitcoin, the virtual currency created in 2008. It is a sort of decentralized account book controlled collectively, on the peer-to-peer principle, from a distributed database. It is the blockchain that ensures the security of transactions by sharing trust. A system reputed to be transparent and tamper-proof, the scope of which goes far beyond currency alone.

What is the blockchain and why are we talking about a revolution about it ? Behind this system for securing Bitcoin transactions lies a concept that bases its reliability on transparency and mutual trust. Some think that the blockchain is led to play a central role in our existence by replacing trusted centralized third parties such as banks, notaries, insurance companies and more.

The blockchain was born with Bitcoin

The blockchain was born at the same time as the cryptographic currency called Bitcoin and appeared in 2008. Bitcoin is used to purchase goods and services ; it can also be exchanged for other currencies. Unlike traditional currencies, Bitcoin is not administered by a single banking authority, it operates in a decentralised fashion through a set of nodes. These form the network through which all transactions are made. A secure public register keeps the history of all these operations. It is considered forgery-proof since it is based on the principle of shared trust.

« Mining » form the nodes to the blockchain

Each transaction is encrypted and stored in a block, which may contain several separate transactions. A block contains a numerical marking from the previous block that attests to its validity. This marking operation is carried out by voluntary users, who are called “miners”. The latter make their time and the computing power of their machines available to administer the blockchain. The miners form the nodes, or rather the links of the blockchain.

This operation called “mining” allows these people to be paid, in Bitcoin of course. The Bitcoin value is maintained by software that adapts the intensity of the calculations to the number of active miners. The more bitcoin miners there are, the more complex the calculations are and the safer the blockchain is.

The future of the blockchain beyond Bitcoin

The blockchain has many advantages. First of all, it reduces bank transaction costs and even eliminates banks as trusted third parties. In addition to digital payments, this technology can be used to transfer other assets, such as securities, bonds, shares, voting rights…

Furthermore, the transparency of the system and its decentralised architecture give it a potential for applications that go beyond the financial sphere. The blockchain being a register, it can be used to establish a traceability on all kinds of products and services. It can also be used to ensure the application of intelligent contracts, programs that automatically execute the terms of a contract.

 

How OBD Scanners Work in Cars

obd scan tool

If you own a car made from 1996 going forward up until today, you might have noticed that the vehicle has some standardized computer systems. The computer systems are responsible for monitoring emissions and electrical sensors within your car as you drive. This has been a major innovation in the automobile industry over the last 2 decades!

However, after recording the information, you will require an On-Board Diagnostics popularly known as OBD tool to retrieve it. OBD scanners can detect problems in your car before you even notice so they can be essential. In this article, we focus on how these OBD scanners work and how they are essential for your vehicle.

How the Scanners Work

If your car is not working correctly, usually there would be a dashboard warning or the Malfunction Indicator Light (MIL) will illuminate to indicate that something is not right. However, these signals only tell you that something is wrong but do not say what exactly is wrong with your car. That is where the OBD scanners come into use.
By plugging the scanner into your car and reporting a code, the device will give you detailed information on what is wrong. Given that today’s cars are far more involved in both electrical and mechanical systems, it can be hard to detect a problem in your car without an OBD scanner.

What are the different types of OBD Scanners?

diagnosing car issuesTwo types of OBD scanners are available, the “code reader” and the “Scan tool” scanners. The code reader scanners can read and clear necessary codes in your car while the scan tool scanners can perform functions that are more advanced.

It is advisable you have the scan tool OBD scanner because with it you can view both real-time and recorded data. What is more is that the advanced scanners can provide advanced troubleshooting information. Even though most people use ODB scanners to test for emissions, the devices have more uses that include measuring different aspects of your car’s performance.

Using a vehicle scanner

The ability of these devices’ ability to provide accurate information, however, depends on how well you use them. For instance, once you get a code, you must define it correctly. If not careful, you might mistake a P0303 code for a P0455 with the first code meaning that you have a misfiring cylinder while the second one means that you may not have screwed the gas cap correctly.

Why Having a car engine scanner is Important

Regardless of how you want to use your scanner, it is essential that you have one in your car. As aforementioned, the scanner can be very critical in testing your car’s performance and possible troubleshooting problems. Moreover, the scanners are very active and suitable bearing in mind that the cars manufactured in this era are far more complicated.

Conclusion

For cars manufactured from the year 1996 going forward, they computerized systems that have made it possible for the use of OBD scanners. The scanners help to measure the car’s performance, troubleshoot problems and provide you with detailed results. However, you should be very careful while defining the codes while using the scanners or you will end up getting the wrong information. An OBD scanner is one that you should have in your car at all times because you can never tell when disaster will strike.
