How Does Satellite Internet Work?

Satellite Internet is falling in price these years and is becoming more accessible. Most of us use regular broadband, mobile broadband or just mobile data via mobile when we are going online.

How Does Satellite Internet Work?

But there are other options for getting online, such as satellite Internet, which is brilliant if you need to be on the Internet in remote areas. There are advantages and disadvantages to the technology that we need to look into.

How Does Satellite Internet Work?

In this post, we will look at the technology behind the Internet via satellite.

What is the satellite?

A satellite is a moon, planet or machine that orbits a planet or star. That is, it actually covers both moons and spacecraft that are man-made.

It will usually mean when we talk about satellite Internet, it is the hundreds of communication satellites that are orbiting the Earth to help us communicate with each other. More than 5,000 satellites have been launched. The word satellite comes from the Latin satellites ‘bodyguard, Drabant, servant’, genitive satellite. (The great Danish)

How does satellite Internet work?

The satellites are used for both telephone, Internet, GPS, data, radio and TV, but increasingly also for Internet communication.

First, the signal is sent from a station on the ground up to the satellite. When the satellite receives this signal, it processes the data in so-called transponders, which basically converts the avenue from the received signal (uplink frequency) to a transmit frequency – also called the downlink frequency.

Before the signal is transmitted again, it is amplified so that it can reach the next satellite or down the ground to the receiver unit. If you have a satellite receiver, be sure to set it at the right angle so that it points directly to the satellite. Then it can pick up the signal sent down from the satellite.

That’s why all satellites always point exactly in the same direction when you look at the balconies on a block of flats.

How far can a satellite transmit?

As mentioned, a satellite orbits the earth and can then transmit or forward Internet signal via radio waves down to a satellite dish.

A single satellite cannot transmit signal to the entire earth, but it can cover a very large area that corresponds to the area that can see the satellite if the weather was clear. There must be a free airline from the satellite to the dish for data transfer. If you come across the ground it is not possible to send the signal through the ground (or outside) and up to the satellite.

Here, however, it is possible to forward the signal from a satellite to the next satellite, and thus shoot the signal incredibly long. It can be received on, for example, a ship in Antarctica.

When a satellite forwards a signal to the next satellite, they can either be made via microwaves, infrared light or radio waves.

What are the benefits of Internet via satellite?

The primary benefit is clearly clear that you can receive the internet signal anywhere on earth.
It is particularly useful for ships that travel far beyond the reach of ordinary mobile towers, but also for people climbing mountains, or staying in particularly deserted areas. Communication via satellite is vital for cargo ships, for example, who sail around the Earth.

Ping time is a challenge

The biggest drawback is that Ping time is much higher with satellite communication, compared to regular broadband and mobile data.

For ordinary broadband, one expects about 80 ms in ping time, but for satellite Internet it is typically between 600-1,000 ms. This means that you have to wait longer, every time you load a new page.

Satellite internet is expensive

The other back of these internet connections is that the data is very expensive to receive. It is not uncommon to pay up to several dollars per megabyte if staying in desert areas.

But as always, this price is set by the demand, and as more and more people are traveling and visiting deserted areas, the price is also falling sharply in these years.

When to switch from web hosting to dedicated server or Cloud solution?

When you as an e-merchant or website owner have to choose hosting, you are often presented with several different solutions. Cloud-based server, shared server or dedicated server.
The possibilities are many. But what are the advantages and disadvantages of the individual solutions? We come in here.

What is Shared Hosting?

Shared hosting is what we call a web space in everyday life. As the name indicates, shared hosting is where you share one server with many other websites.
In this way, the server’s resources are distributed to the many different websites, and you therefore do not have as much power to do with.
This, of course, is also reflected in the price you end up paying. You can get an acceptable web space down to 10 DKK / month .
However, there is a big difference between the prices and the performance you get from the various providers. Personally, I always recommend the Bronce package at Unouro (which netkablet.dk also runs on), as you really come a long way with a standard web space with them.
I even have lots of smaller websites that run really well, and I always start on a regular website. shared hosting at Unoeuro.

If your website is reasonably built up and you have few and simple SQL calls for your database, you can easily have about 3,000 visitors a day at a standard web hotel at Unoeuro.

A good example of a website with about 3,000 visitors per day at peak periods, my own blog is GoDownsize.com , which is hosted on a shared web hotel. When we post a new Youtube video on the corresponding Youtube channel, it often hits thousands of visitors at the same time, and it still runs really well and stably.
So it is not necessarily the number of users who decide whether to use a shared or a dedicated server, but to a great extent how technically demanding your solution is.

Benefits of shared hosting

As previously mentioned, you do not have a very high degree of freedom with regard to the technical aspects of your server. However, this can also be emphasized as a significant advantage.
When choosing shared hosting, it does not require the smallest IT skill, and it is often just plug and play.
In addition, many hosts are super skilled at making email setup, installing the most common CMSs and easily linking subdomains.
As mentioned, the prices are between NOK 10-200 / month, and that is an incredibly cheap solution.

Disadvantages of shared hosting

For new and small websites, there are no significant disadvantages of shared hosting. It is only when your site has grown very large.
If you have a larger website with many visitors and advanced calls to your database, your website will therefore be slow.
This goes beyond user-friendliness as well as your Google placements.
With shared hosting, you also have limited freedom in setting up and configuring software. Some providers have also set up their system so that all websites struggle with each other about the server’s resources.
This is not a good solution, as your website may run very slowly, because other websites on the server draw heavily on all server resources.
There are few shared hosting plans that run this way, and if you choose Unoeuro, you are at least sure there is no site on the same server as you and sucks the whole power.

What is a Cloud solution

In a typical Cloud solution, multiple virtual servers are connected, and you can scale your space and performance as needed without maximum performance.
Your website can therefore draw on several different servers as needed.
A good example of a solution that requires a cloud setup is the shopping portal Katoni.dk , and they have therefore chosen a cloud solution. They collect clothes, shoes and accessories from Danish online stores and have over 200,000 products.
According to Martin Skovvang from Katoni, they have chosen this solution because they give them the flexibility they need for their setup consisting of both web servers, databases and a number of other systems.
He says:
We can adjust everything from number of CPUs to the amount of RAM and set up load balancing as well as firewall rules with a single click.
Flexibility means that we can adjust resources exactly to the need, for example. the web server does not require as many RAM as, for example, the database.
The products can be sorted in many different ways and this is where extra server power is needed. If you look past one of their categories, notice their top filter that allows for quick filtering.
They actually started at a web site at Unoeuro, but gradually the site became more advanced and their filters and other features slowed down. They have therefore chosen a cloud server at Google , because you get much more for your money by purchasing the solution from one of the major providers abroad.

Benefits of cloud hosting

The advantage is that you can scale very quickly and efficiently.
If your traffic suddenly rises, Google and Amazon’s cloud solutions will allow new servers to be automatically started from one second to the next, so your site will not be shut down.
The good thing about cloud is that you only pay for the servers that are active. Ie that if you need 3 extra servers and pumps for a short time while you are running a TV spot for your website, then you do not have to pay for these servers beyond the time they are activated.

Disadvantages of cloud hosting

As with the dedicated server solution, you need an IT expert if you want to run in the cloud.
It simply requires a little more knowledge of servers and setup when switching from a shared solution.
In addition, it is relatively expensive, and therefore you should never start on a cloud solution, because the cheapest and best for new sites is always a cheap shared hosting plan .

What is a dedicated server?

A dedicated server is, as the name also indicates, a server where one should not share its resources with others. This way, you have an entire server’s power allocated exclusively to your site.
However, a dedicated server requires significantly more IT skills and a larger investment.
When investing in a dedicated server, one must have a good idea of one’s future needs. It is possible to expand and scale down with RAM and disk space, but the actual capacity is not just up or down.

Benefits of a dedicated server

A dedicated server gives you the ultimate freedom in choosing software and hardware, expanding the frame and, not least, a significantly larger capacity.
However, this is also reflected in the price.
In addition, a dedicated server can handle a larger number of users and more advanced solutions than a standard web site can.

Disadvantages of a dedicated server

The disadvantage of a dedicated server lies in the reduced freedom that one has in terms of up and down adjustment of needs. If you have very large volumes of traffic (eg webshops that run TV commercials during periods), you can run out of power.
If you’re looking for a more scalable solution, look for a Cloud-based server.
A dedicated server requires a lot from you as an IT man. However, it is possible to purchase a server with SLA (Service Level Agreement). This means that the provider sets up the server and provides maintenance. If you are not an expert in setting up servers, I would definitely recommend that you get help.
Without the right setup, your website may very well run slower on a dedicated server than with shared hosting.
The fact that you can use all the server’s forces is of course also reflected in the monthly price. Typically, it is around 600-4.500 kroner / month depending on how much service you need and the power the server needs.

The conclusion …

Whether one should choose one or the other depends 100% on one’s needs and on how technically skilled one is.
If you have a smaller website or a new website, you always have to start a shared hosting with fx. Unoeuro .

What is 5G? | Understanding 3G, 4G LTE & 5G (explained to beginners)

3G technology made it possible to use the internet for far more things on the mobile. 4G (also called LTE) technology has given us internet that can almost match the broadband we have in the home.
And now there will soon be 5G internet.
What is the 5G Internet? 5G is a next generation of the 4G mobile network, also called LTE. With 5G we get a much faster mobile network, which also has no outcomes. It opens up completely new applications.
In this article, we explain the difference between 1G, 2G, 3G, 4G and 5G. You get the basics around the 5G technology and the difference to the technology we have now.

In this article, we explain the difference between 1G, 2G, 3G, 4G and 5G. You get the basics around the 5G technology and the difference to the technology we have now.
1G, 2G, 3G, 4G and now 5G – what does that mean?

The G that comes after the given number stands for generation .
So it says that there has been a marked shift in technology from one generation to another. Within each generation there are a number of different technologies, including a number of improvements.
For example, 4G is not the same in the EU as in the United States.
Here you use different technologies to deliver a similar product in relation to download and upload speeds, but also in relation to delays (ping).
1. 1G: First generation of the mobile network enabled one to make calls to each other.
2. 2G. The second generation allowed us to send SMSs to each other.
3. 3G. The third generation allowed us to start using the Internet mobile, but particularly limited in relation to the broadband you had in the homes.
4. 4G / LTE: Fourth generation gave us a clear improvement on third generation mobile networks. This made the Internet much more accessible to mobile users. However, still with disadvantages in terms of delay and speed.
fact
Note: Some believe that 4G was just another version of 3G, and so should just be named 3.5G.
Nevertheless, there is a marked difference to the third generation in terms of usability, price, speed and delay, which justified the name.
Fifth generation (5G) has the potential to make the mobile network the broadband we know from home. This can be done by a combination of technologies that enable you to speed up the speed and down the delay.
If this happens, you will probably see an explosion of new devices using the mobile network.

The Internet of Things helps set demand

Internet of things is the concept of the development that happens when ordinary things like refrigerator, car, lamps etc. are connected to the Internet. This gives the ordinary things new features and increased accessibility.
The Internet of things has gradually begun to be a larger and larger part of our lives and this will inevitably be an even bigger part in the coming years.
This puts more pressure on our internet. Most of the things will be connected to your private home network. But many of the things you take away from home will need cellular networks.

The potential is huge, but it requires that we have a well-developed network.
One of the things that 5G technology people track really will boost the development of self-driving cars. And right here it is incredibly important that you have a fast and stable network with a low delay.
Particularly when it comes to technology such as self-driving cars, a better network is needed.
It is a bit of a no-brainer that it is not possible that self-driving cars lose the connection or are delayed for a second to receive information.
At worst, it can cost human lives.

What can we expect from 5G?

Although the technology has not yet been developed, we can expect that the combination of technologies will contain approximately the technologies we describe further down in the article.
If these technologies become a reality, then we can expect that the 5G internet will be:
– The more robust – the 5G network will be significantly more stable than the 4G network.
Faster speeds and lower delays – With a ping of as low as 1 ms and a theoretical maximum speed of 20 Gbit / s (realistic speed initially will be between 100 and 300 Mbit / s), this network will be able to measure the broadband we have in the homes. And it will be useful for eg self-driving cars, Virtual Reality and much more.
More people can use the same network – the 4G network has limitations on the number of users in the same location. Which we can for example experience for concerts, festivals and the like. The 5G network can handle up to one million units per unit. square kilometers.
All in all, this means if the outcome is as predicted that we will see much more for the internet of things.
Far more common everyday things could be connected to the Internet.
It can be a huge step in the development of new technologies that can be in line with the development of the smartphone.

When can we experience 5G?

Already you are already experimenting a lot with 5G networks, but that does not mean that the launch is just around the corner.
Compared to 4G, it was not available to anyone for a long time either. Even now, there are a number of areas in Denmark where 4G is still not an option.
So there are probably many years before the technology is available to all Danes regardless of where you live.
But..

Because technology is not yet developed, you can only predict when it will become available. The most positive predictions say 2-5 years, but the more negative say 5-10 years.
But let’s hope that the technology will be ready within the next half decade.

What is 5G and what makes it special?

This is harder to answer than as so.
As the 5G technology is not yet fully developed, we can only look at the range of potential technologies that can be included in the overall 5G technology.

The technologies that are likely to constitute 5G each have advantages, but also disadvantages. And, as we elaborate further below, there is potential for the technologies to address some of the disadvantages that may be.
It does just that this combination of technologies seems likely if you can get them to work together.

Higher frequency – millimeter waves

We start with this technology, which is probably indisputable whether it becomes part of 5G or not. For one of the major future problems is predicted to be interference between the various signals.
If one can remember the physics lessons at the end of the elementary school or from the time at high school – then one of the waves’ properties is that they can make interference.

Browser Extensions | You must know how to install thease?

Browser extensions have thus been available for a long time – although many do not know about this type of software.

Browser Extensions | You must know how to install thease?

What is a browser extension?

A browser extension is an extension of a piece of software (the browser) you have already installed. The browser is the program that you use to navigate the web.
Some extensions give you faster browsing while others add features or remove advertisements.
The most common browsers are Internet Explorer, Safari, Chrome and Firefox. Read more about browsers for mobiles (iPhone) .

Most browser extensions are developed by private individuals and companies that do not make the browser itself. There are also browser extensions developed by the company behind that browser.

What types of browser extensions are there?

The amount of browser extensions is huge, and more and more are being developed all the time.

The type of browser extensions is also evolving, so it now includes games and more app-like extensions. You can therefore find more of your favorite apps now as browser extensions.

Chromebooks are Google’s laptops, where the browser is the central operating system. That’s why there’s virtually everything you need in the form of apps or extensions. This applies, for example. add-ons, calculator, writing software, imaging programs, multiplayer games, online backup, etc.

The best browser extensions:

Magic Actions for Youtube – Magic Actions helps you to an improved version of Youtube. It contains many options for customizing Youtube. For example, you can do so that Youtube always plays the videos in 720p, 1080p, 2k or 4k.
You can make the white background black so that the white light does not cut you in the eyes. You can use the cinematic view feature if you don’t want full screen, but a larger screen than what Youtube usually offers.

Cite This For Me – As a student who has to write major academic assignments, it is often difficult to keep track of sources and where you are just pushing this specific quote. It helps this extension to you. If you find something on the web, which you have doubts about where it came from, then this extension can guide you to the author at the source.

Adblock – Adblock is one of your most famous add-ons available to all browsers in many different versions. In all its simplicity, Adblock blocks advertisements on websites and in Youtube movies. There are many different add-ons that have this feature, but Adblock is the most widely used.
Bonus info: Are you tired of Spotify advertising? Then you can avoid them without paying for Premium if you install an adblocker and use Spotify’s web player instead of the program.

Grammarly – The extension that spells for you (in English). An absolutely brilliant extension if you write assignments, emails or anything else in English. It corrects both misspellings and sentence errors.
These are just a few of the many brilliant extensions that exist. These are selected to show the wide range of extensions that exist.

A good idea before installing an extension is to check whether the extension has received good reviews or whether it has received any remarks. You can often look at the browser’s official extension page, but otherwise do a search online.
However, you must be aware that extensions have to slow down the speed of your browser, so if you want lightning-fast Internet browsing , be careful with the number of plugins.

8 tips for good internet security on the journey

Internet security is a topic that has really come up on the agenda and it is with good reason. Because when we use the Internet it is with certain risks and it becomes more uncertain when using less secure connections.
When you are traveling you can never be absolutely sure of your internet connections you connect to, therefore we have here gathered the best advice and guides on how to best secure yourself on the journey.

8 tips for safety on the journey

The best thing to do when you are on the go is to be a little paranoid when it comes to Internet connections. Remember to always take your precautions – especially when it comes to sensitive data!

– Use VPN for all internet traffic with personal sensitive data.
– Free and open WiFi spots are the least secure.
– Use a program to hide your codes and credit card information.
– Never log on to an E-box or online bank on non-secure networks and always use a VPN      program.
– Consider using external hard drive rather than online backup for images and video.

# 1 – Use VPN for all Internet traffic

Although it may seem a bit paranoid, consider all networks you encounter on the journey as being insecure. The only exception can be a higher standard hotel, where you get a unique code for the internet that you need before you can sign in to Wi-Fi.
For people who have control over hacking, it is all too easy to get your computer or activity off if you are on a public network.
One way you hide from people with bad intentions is to use a VPN program.
The VPN program hides your internet traffic by camouflaging your IP address. We have made a longer post about VPN programs , where you can also see which free programs are the best.

# 2 – When to use your credit card or online bank

If you have left for a long time, then there is certainly a time when you need to check online banking, E-box, use the Dankort or other person-sensitive data.
Here it is particularly important that you ensure that the connection you use is reliable.
There are a number of excellent programs to hide your sensitive data. One of the programs is MaskMe, which can mask your credit card information, phone number, address and more.
MaskMe is a browser extension that can be downloaded for free for both Chrome, Safari and Firefox.
There are many other similar programs, but even if they increase security, you should always use a VPN program if you need to use your credit card online, log on to online banking or E-box.
Read more about browser extensions in our article on the same topic.

# 3 – Beware of fake networks

When you log on to a network, don’t say yes to it’s home network. If you click yes, your computer will be visible on the network, which it may well be for anyone.
If you want to log on to the hotel network, be sure to ask the hotel staff about the exact name of the network and the code.
Hackers sometimes make WiFi spots with the name of a hotel and free login. They do this to entice you into the network and thus make you vulnerable.
It can therefore be an advantage to use your own mobile broadband network instead of ordinary. broadband if the hotel or hostel does not work safely and reliably. You can buy it via a sim card with data for your mobile.
However, it can be quite expensive in the long run unless your telephone subscription has included foreign telephony. Please note that you cannot use unlimited amounts of data here.
So, using your own mobile broadband network abroad, make it short and only for the most important things.

# 4 – Use External Hard Drive over cloud backup

If you take many pictures or movies that you would like to save, it may be a good idea to wait for it to be transferred to a cloud server until you get home.
Often, these are large files, which (depending on the connection) can take a long time to upload. And when you transfer the files, you risk that others are included.
Again, a VPN program can help you with security, but if you use a free VPN program then there is either a limit on the amount of data you can use with it actively or the speed of internet traffic.
So unless you have paid for a VPN program, it is often safer and faster to use an external hard drive as a backup.

# 5 – Secures your logins with a strong code

Change your logins before traveling so you don’t have the same code for all your sensitive pages.
If you already have an easy code, you should change it to a more difficult code with both upper and lower case letters and preferably numbers. It is important that you do this, even though it may be difficult to remember long codes. Here’s how to make a secure code .
Be sure to memorize it and save it if necessary. in printed form at home so you do not forget it.

# 6 – Camouflage iPad / Computer with Creative Wrapping

With a little creative thinking, you can prevent people from seeing you have an iPad or ultrabook on the journey.
Check eg. This Bible cover that makes the iPad look like a Bible:Bibles will probably never be stolen

# 7 – Make sure the screen locks after a very short time

Under system settings, be sure to set the time down for the time before the screen freezes and asks for your password to unlock.
This way, you minimize the risk of other people accessing your information.

# 8 – Don’t send personal info via email

Everything you use online is more vulnerable when it is a network you do not know.
Therefore, do not send personal data in emails, especially while traveling. Never ever send your credit card details by email. The same applies to codes for online banking and CPR numbers, etc.
If the accident is out…

If you were to be so unlucky to lose your computer on the trip, or to have an important PIN stolen, then it is important that you contact your bank quickly and cause them to block your payment cards.
In addition, make sure that the damage is limited as much as possible by changing all the passwords you have.

That’s why it’s a great idea to keep track of your passwords and make sure you find the codes, a place that is not stored with your computer, your purse or your mobile.

 

How old is the internet and who invented it?

The World Wide Web (www) is from 1994, but the Internet technology itself is much older. Denmark has always had a strong international position when it comes to digital infrastructure.

The first Danish internet connections were the universities, as has been the case in many other countries.

Roots back to American scientists and the Cold War
Let us first take a look back at the emergence of the Internet before we look at how it works. The road to the internet we know today with lightning fast broadband has been a development rather than an isolated invention.

The need and the idea of ​​sharing information via the Internet arose in the 1960s among researchers and in the US military.

The computers of the time were large and immobile, so to share information one had to either move to the computer’s location or send data on magnetic storage devices with the traditional mail system.

During the Cold War, the US military considered ways to communicate even after a nuclear attack. The existing telephone network seems to be too vulnerable.

It led up through the 1960s to the establishment of the APRANET (Advanced Research Projects Agency Network), which in 1969 first established a stable connection between two computers.

There were very few computers connected to the network at the start. Up through the 70’s, more and more networks were created. The idea of ​​getting all computers and networks to communicate together was the dream scenario – but how?

This was resolved on January 1, 1983, which is considered the internet’s birthday
The introduction of a new protocol system (TCP / IP) invented by Vinton Cerf allowed different computers on different networks to communicate with each other.

In 1991, the foundation stone was added to the internet we know today, as Swiss Tim Berners-Lee invented the World Wide Web. The groundbreaking thing was that this not only could send information from A to B, but in itself was a platform for information.

Who invented the Internet?

Electro engineer Robert Elliot Kahn first connected 20 computers to the International Computer Communication Conference in the fall of 1972, which later formed the basis for he and Vinton Gray Cerf (the two basic) to invent the two primary protocols (set of rules) that became the basis of the Internet :

IP (Internet Protocol)
TCP (Transmission Control Protocol
It all accelerated in the late 1980s.
In the mid-1980s, Danish Network for Research and Education was established , which in 1987 cursed the Danish universities via NORDUnet , a non-profit collaboration between Denmark, Norway, Sweden, Finland and Iceland.

The website NORDU.NET is also the oldest active domain name. It was registered January 1, 1985.

Today, NORDU is still working on even better digital infostructure, inter alia through an intercontinental connection between Europe and North America with dizzying fast internet speeds.

The first broadband connection in Denmark

The first broadband connection in Denmark, Stofa can take credit for. Already at that time, Stofa Denmark’s second largest cable TV provider was, and it was just a single city that was connected to the fast connection. Read more about Stofa’s history here .

It was not until the year 2000 that TDC launched their competing broadband product.
The first time you referred to the so-called internet, was in 1974 As for someone marking the birthday of the Internet.

But it has of course been a lot of people and dates involved in the creation of the Internet, as we know it today, and therefore there is also wide discussion about when the internet was actually created.

Some believe it is from 1969, others say 1973 and again others 1983 ( source ).

On April 3, 1993, one could for the first time make use of www, and thus, the acquisition of domains and the creation of websites on the premier internet came a real boost.

What is status today in Denmark?

Today, we have one of the world’s best and most stable networks of copper cables from TDC and Fiber from the power companies, which means that together with our neighboring countries, we are at the top 10 over internet speeds.
Especially the Netherlands, Sweden and Norway have really good and fast Internet, and because we stagnate a little in the roll-out of the Fiber network in recent years, we are lagging a little behind.

What is Artificial Intelligence | What can we (and is it dangerous?)

The Matrix, Westworld, I, Robot, Terminator, Bladerunner and so on. Common to these films and series as well as many others is the theme of the robots (trying) to take over the world.

The idea that robots can take over is made possible in the films by having invented AI, which makes the robots independent thinkers.

If you follow a little bit in technology news, you will know that Google, OpenAI and several major companies have made some major steps in the development of AI. But does this mean that we have to worry about robots taking over the world?

I say in this article why we do not think we need to worry about robots taking over the earth. And why we should be concerned about a number of other areas.

What is artificial intelligence?

There is a lot of confusion in this area, so let’s start with a definition.

What is artificial intelligence?
Artificial intelligence is a field of computer science that deals with getting the computer to perform tasks, based on calculations reminiscent of human thinking. Work is being done to enable the computer to perform more advanced tasks than the computer can do today.

It is important to define some different technologies if we are to become wiser or discuss artificial intelligence in a well-informed manner.

First, artificial intelligence is not the same as artificial emotion. Emotions are what we humans use as a motive for acting as we do, whether it is the desire to become richer, become more loved, and so on, so most of our actions have a rationale in our feelings.

It is, of course, somewhat simplistic, because humans also have drives and general rationals that defy our feelings and drives. It acts as a motive for our actions. But to make things easier, we call it emotions.

Why won’t the robots take over the world?

Machines do not have the ability to feel for themselves and thus the machines do not have the opportunity to self-motivate their own actions. A robot will well be able to make predictable actions, but it is based on the people who have made those who have made mistakes or missing limitations.

In the movie “I, Robot” the problem arises with the robots, because their limitation on always protecting man is compromised because humanity is the greatest threat to itself.
However, robots or machines do not work – at least not unless artificial emotions can be invented.

It’s hard to imagine if it is possible to create artificial feelings, but it is quite trivial to discuss whether there is more to human emotions than just a small electric charge in the right places in the brain. Independently of what you think about the dilemma, we are very far from the scenario.

There are two branches within the thinking of artificial intelligence:

Soft AI – here you don’t think the computer will be able to do everything a person can do.
Hard AI – here you mean that man alone is atoms and chemistry, and that it is therefore possible for the computer to do everything that a human being can do 100%. Eventually.
As you can see, it belongs to those who think hard AI is not possible.

The biggest AI problem is data!

Facebook, Google, Microsoft, the American net doctor and so on …. The scandals are many in relation to data security. There are so many different cases where data has been leaked, sold or passed on. And data is no longer just a question of what advertisements you get on Facebook.

Data can change election campaigns, data can predict diseases, pregnancies, when you die and so on. And when data can, companies that have these data can do so.

It seems surreal, but there are examples from the US, for example, where young women have felt a little lean. Then they visited the American version of the online doctor. This site has sold information about their visitors to eg Walmart, after which some of these women were sent baby packages.

Because of this data, the companies could find that the women were pregnant before they even knew it.
It is not for us to find the silver paper caps and move far away from all technology, but that means we have to decide on our movement on the web and how far we will allow the companies to use the data they have.

Lack of ethical rules for the use of AI
The new personal data law in the EU is a clear improvement for private people’s privacy, but there is still room for much improvement in the rest of the world, but also in the EU.

It’s not for appointing Google as the big bully at the moment, but because Google is a leader in terms of AI, it’s two cases from those we highlight here.

Example 1:
Google has enabled AI to assess the likelihood of a patient dying.

Example 2:
The new version of Android comes with an improved version of the Google Assistant. The new Google assistant has become the focal point of a major ethical discussion because the assistant, using machine learning, has learned to imitate people to such an extent that it is virtually impossible to know the difference between man and machine.
Specifically, it is a feature where you can get the assistant to book eg a time at the hairdresser for you. It will happen in the way that you say “Hello Google book a time by example Frisør Hansen on Nørrebro on Thursday between 10 and 14. Then the assistant finds the number himself and does not call the hairdresser with your number but with the assistant’s own.
Here it presents itself as your assistant and book a time.
This is not a problem in itself, but because Google has had so much data available in combination with machine learning, one cannot hear the difference between an ordinary person and Google’s machine.

  • t’s a very nice feature for us users of the Google Assistant, but it requires a question of morality; must a machine pretend to be a human?
  • Example 3:
    A researcher has developed a program that can, with pretty good accuracy, assess whether a person is homosexual. The program can use data from eg public cameras to assess the likelihood of homosexuality. The researcher has developed it without a normative project, so as such it should not be used positively or negatively. But the program can have some terrible consequences especially if it is improved.
    Homosexual rights are already squeezed in several countries and in some there are even prison or death sentences to be homosexual. If such a country or dictator gets its hands on this program, it could mean greater persecution of homosexuals and such a case would most likely mean loss of life.

How can a problem arise with the AI ​​technology?

The problem with AI, machine learning and deep learning is that we are now starting to use machines to process data in much larger quantities than we have previously been able to.

Previously, we have had to process data even with human power, but more advanced computer programs have made this much easier. The Internet is a land for collecting data because we entrust most of our private data to businesses behind apps, computers and mobiles.

It is therefore important that we have whistle blowers and people who dare to question the use of data.

iPhone GPS: How Good Does It Work? 9 facts and good tips

GPS function on iPhone works incredibly well and often provides better data than other known GPS systems.

But how good is it compared to the big GPS brands, we look more closely at this article.
First, we just have to fully control how we use the GPS part on our iPhone.

How to turn on and off GPS on iPhone
Settings> Anonymity> Location Services.

Here you can set whether your location services should be turned on (or off) for all apps at once. You do this by turning the top menu on or off. See the photo below by the number “1”.
When you click this menu, you can also choose exactly which apps access your location services (GPS data). See the figure “2” on the menu below.
It is important to check these settings, as many apps have access to your GPS data. It doesn’t make much sense that, for example, a browser and a memo app must have access to your GPS data.
Here you have the opportunity to decide for yourself which apps have access and when they can access your location.

How much data does GPS use on the iphone?

If you use your GPS for example the Google Maps app, it draws approx. 1 Mb per 20 minutes or 0.5-1 Mb data per 15 km. However, it may vary somewhat depending on which other apps you also use that have access to your GPS.

Many of us use quite a few different apps, with access to our GPS data, and it can quickly become a power outlet. Here are some of the apps that most often use data in the background to track GPS data:

Speed ​​control apps
Google Maps
Health app ( iPhone Pedometer )
Camera app
The Itinerary
etc.
It is important that you set these settings yourself so that you choose whether they have access to your GPS data at all times, using the app or never. These are the three options you have. You can look at the picture above how to set these privacy settings.

As a starting point, there are a whole bunch of apps that use your GPS data, and then you can quickly use a lot of data on this!

Which GPS app for iphone?

There are many different apps for iPhones that can help you find your way with your GPS. I personally personally am a fan of Google’s Google maps App, which has really many fine features built into.

It can eg. show you where the queue is on the highway, and it also has data for gas stations, eateries and many other user-added information.

However, there are also many other apps that can provide an interface for your GPS.
Gaia GPS for cycling and hiking
The Gaia GPS app is a pretty excellent GPS app that gives you a lot of routes if you, for example, love to ride mountain bikes. It also great if you love to walk in nature on the walk.

It costs approx. $ 20 a year, and then you have access to a lot of routes, courses and maps of areas.

It also features a number of routes made by National Geographic Trails. They are great if you like to hike in American National Parks.

How much battery does the GPS use?

When it comes to battery consumption , it’s another matter. Here, the mobile can quickly be drained of power when, for example, you have Google Maps turned on.

My little old iPhone 6S typically lasts only 60-90 minutes on a full charge if I actively use GPS with the monitor on all the time.
This happens partly because a lot of GPS data is received and sent, but this typically also happens because the screen is switched on all the time when you use it as an active GPS.

It can therefore be a great idea to turn off the screen and just get to know the roads and instructions through your headphones. That way, you save a lot of power because the battery does not light up the screen and update all your pixels all the time.

It varies greatly from app to app, how often GPS data is sent and received. You can see the small GPS icon at the top of your iPhone screen every time the GPS is turned on. Often, an app will only ask for GPS data if, for example, you move to a new location.

But if you are actively using a program like Google Maps, it will constantly be sending and receiving.

How good is the iPhone’s GPS for Garmin, Tomtom etc?

Garmin and Tomtom are the two big (and old!) GPS providers for cars, motorcycles and so on.

But how does their performance compare to the GPS built into the iPhone? We’ll look at that here.

I even bought a Garmin GPS app and drove it parallel to my iPhone’s Google Map apps all the way to Pisa in Italy. Here are the advantages and disadvantages I found with the two systems.

I was really happy to see how fast I had to drive on European highways.

These data were not available on my iPhone’s Google maps app, but I could see them on my Garmin GPS. It probably saved me from more than one fine along the way.

In addition, the Garmin GPS was also better at delivering traffic data along the way. Sometimes it could show where it was queuing, but at other times it was Google maps that were better at showing the red roads along the way.

One of the biggest disadvantages of GPS devices is that they have not always updated the latest map data. This means, for example, that you do not necessarily know all the routes when you drive off the major roads. The same goes for my built-in GPS in my Ford Mondeo. It does not know the new bypasses around Silkeborg, for example, as I have not figured out how to update its map data.
Is there gps in my iphone?
Yes, there is GPS in your iPhone. The first model did not have GPS, but all models have had GPS and it has your new iPhone as well.

If you do not find that your iPhone will receive and send GPS information, it is either because you have disabled the feature in Settings> Anonymity> Location Services or because the sensor in your iPhone has broken.

How the GPS works on the iPhone

GPS stands for “Global Positioning System”, and as the name suggests it is used to GEO tag the location for the mobile.

There is, physically, a small GPS chip in your iPhone that communicates with satellites around the globe. By contacting at least three satellites, your iPhone can always locate exactly where you are.

This is primarily done through a number of American satellites, and there are approx. 30 of the kind.

See where the iphone has been
With the “Find my iPhone” function you can find your iPhone if you have lost it, but where do you see where it has been?

You can check with two different systems:

Google map part and
Apple also has control over where your iPhone has been.
With Google’s “Places You’ve Been” they keep track of your location history. Ie they have control over where and when you have been in different places.

With Apple, you can also see exactly where you’ve been through your GPS, but keep tight because this data is well saved!

Here you will find them:

Go to settings
Tap on “Anonymity”
Touch “Location Services”
Press “System Services”
Tap on “Essential Locations”
(Here you need to use your code or touch ID to move on)
Here you have your history of where you have been, or rather where your iPhone has been.

Who has access to my GPS data?

Everyone who has access to the iCloud account has access to see where you are via the find my iPhone feature. It is therefore important that you do not give your code to iCloud to other people.

Google Chrome browser overview and comparison with other web browsers

Browser Google Chrome without exaggeration can be called the most popular web viewer at this time. According to statistics, more than 750.000.000 people use this browser.

When Google thoroughly won the search market worldwide (only in Russia and some countries of the former Soviet Union, Yandex still leads by a large margin), it became necessary to expand business with various additional and related services.

NEW GOOGLE CHROME BROWSER

In sincere concern for the satisfaction of the smallest needs and wishes of its users, Google has developed and presented to the world The Internet Brand new, own web viewer.

Google Chrome browser is a combination of speed, security, user-friendly, minimal design.

At the time of entry into the market, Chrome was a completely unusual, one might even say, innovative solution.

In those days, the general trend was to create complex interfaces and programs with a huge number of functions, for the most part not needed and even incomprehensible to the majority of users.

Take, for example, known to all Firefox. It should be added to the browser a few toolbars and from the main screen there is only a narrow strip. This problem was solved by the developers in the new Chrome browser.

Find out how easy it is to clear cookies in Chrome.

Google’s browser has the most liberated interface. In fact, there is only an omnibox, a combined address and search bar, and the rest of the space is occupied by the viewing window.

At first, Internet users did not realize their happiness. There were numerous critical reviews in the direction of Google Chrome. Gradually, the numerous squad of users got used, and the browser quickly began to conquer the audience. If you are interested in information, how to clear the cache in Google Chrome, then look at the information here .

Despite the fact that Chrome is not part of the standard Windows programs, Google managed to convince a decent part of the Internet market to love this particular browser. And today, Google Chrome is among the top four most popular web browsers, along with Internet Explorer, Operand firefox .

Despite the outwardly poor interface, Chrome is second only to the number of widgets and extensions Firefox. If desired, from a simple browser you can create a multi functional machine that can satisfy the most demanding tastes. The special advantage of Google Chrome in the use of a multiprocessor engine. Each window, each event in the browser is provided by a separate process. So, if one of the windows hangs, the rest continue to work fine. The browser can not stop completely. This fact makes Сhrome the most reliable browser of all.

In addition, as in Windows , Chrome has in its functionality a process manager, with which you can disable any hanging process or simply disable unnecessary ones in order to speed up the work of the program, reduce memory consumption.

Since Chrome has already appeared in the field of other popular browsers, competitors were taken ideas useful options.

For example,Internet Explorer borrowed the ability to create shortcuts to favorite sites for quick access on the desktop. Enormous possibilities for modifying and improving the browser appear to the user after opening the so-called “App Store”. The choice of a wide variety of widgets and add-ons, perhaps, even exceeds the famous collection of extensions of the Opera browser .

The only thing Opera superior to Chrome, it is the presence of a convenient built-in email client. For its part, Chrome is focused on the use of numerous services of Google. It has its own mail, cloud disk, joint documents, social services, YouTube video hosting . Access to all services is easily provided from the Google Chrome browser itself.

The further progress of Google Chrome was expressed in the active development of the mobile market. The Internet. Unlike other browsers, which in mobile versions are much inferior in functionality to desktop versions, mobile Chrome is in no way inferior to the fixed version. For webmasters who create and promote their websites, this browser will be very useful in that it has a lot of analytical extensions.
