18 tips and tricks for Android 9 Pie


Only about 10.4 per cent Android smartphones run Android 9 Pie as of now, as per Google. Therefore, as time passes, eligible smartphones are continually getting the update to Pie. Additionally, Project Treble has ensured that several phones already have the beta versions of Android 9. Smartphones out there are vying for their own tasty slice of Pie. Android One phones, Samsung Galaxy J series, a number of LG smartphones and many others will be getting the update somewhere around the last quarter of this year. Smartphone users who receive the update the Pie can make the most out of their phone by using some of the nifty tips and tricks made possible by this update. Let’s have a look at 18 such tips and tricks smartphone users can utilise with Android 9 Pie.
Quickly message a contact who didn’t answer your call
If you call a contact and they fail to answer your call, an alert will pop-up at the bottom of the Phone app which will prompt you to send a message to that contact saying why you called. Once you tap that alert you will be taken to a new message screen which also houses some suggested responses and a field where you can type your own message. Once you have composed the message, you can directly send it, without having to open your Messages app.
Rotate your screen even when auto-rotate is off
Smartphones use accelerometers to change orientation depending on which way the device is being held. However, we’ve all witnessed its sensitivity which sometimes causes false switches, especially when you’re lying down. This is why many people turn auto-rotate off. In Android Pie, there’s a fix to this issue which works when auto-rotate is turned off, just as many people prefer it. Suppose you’re using Chrome, like the image above, and you flip your phone to view the website in landscape mode, a small icon will appear at the far right of the navigation bar that resembles an auto-rotate icon. Tap it and the phone’s orientation will be locked in landscape mode. Flip your phone upright and the icon appears again. It’s quite genius!
Select text or images in the Recent Apps window
This feature is exclusive to Pixel devices only, for now, however, it is very useful so we decided to include it in our list. The brand new multitasking or overview window in Android Pie is not just a snapshot of all your recent apps. Instead, it can be used to select or copy text and images which can then be shared or pasted in another app. When you’re in the recent apps window, you need to long-press on a screen of your choice to either select a picture or bring up copying handles without needing to actually launch the app. This copied data can then be brought over to any other app.
Connect five Bluetooth devices at the same time
Previous versions of Android only allowed users to connect to one Bluetooth audio device, however, with Android Pie that number has now been raised to five. So, you will not need to switch between paired devices any longer when you want to use another one. All you need to do is connect to additional devices. In case you actually want to reduce the number of devices your smartphone can concurrently connect to, first enable Developer options by clicking on Build Number in the About Phone section in Settings continuously and then scroll down to Maximum connected Bluetooth audio devices option and select a lower number.
Turn any app action into a permanent shortcut
Android’s App Actions are actually astonishingly useful but can be a pain to access if you want to use them often. To obtain easy access to any app actions that you use regularly, you can simply make it a shortcut on your home screen. Tap and hold an app, and then do the same for an app action that pops up in the list and then simply drag it to your homescreen. This way you can easily access the app action you require, even if the system shuffles around the actions and it is lost from the drop-down list.
Turn on dark theme
Android Oreo did kind of house a makeshift dark theme or mode on Pixel phones, which triggered only when a predominantly dark wallpaper was applied to the home screen. This dark theme was applied in the app drawer and notification shade. Now, with Android Pie, you can enjoy this sought-after feature with any wallpaper. Go to Settings > Display > Advanced > Device Theme. Here you can choose the Dark theme or allow it to change automatically based on your wallpaper.
Quickly put your device on vibrate
The volume slider has changed significantly in Android Pie. It appears on the right side of the screen instead of the top, however, the appearance isn’t the significant change we are talking about. The update has given users a couple of ways to put their phone of vibrate really quickly. The best one, in our opinion, is a key shortcut. Holding down the volume up and power buttons together will trigger the phone to go into vibration-only mode. You should feel a small vibration when this has been activated. Additionally, you can also tap the button on top of the ringtone volume slider on screen to immediately put it in vibration mode.
Gesture navigation
Android Pie has adopted a more iPhone X-style navigation system which ditches the overview button and adds more swipe controls. The controls are - swipe up on home to see all the recently used apps, and then swipe up again to access the app drawer. You can tap the elongated home button to return to your home screen at any time. When in recent apps window or overview, you can swipe right and hold on the home button to slowly scroll between apps and release to open the middle app. You can also swipe right and quickly release on the home button to go to the previous app. This system takes some getting used to, but over time it can prove to be faster than the conventional 3-button layout system.
Mute all repetitive notifications
Android Pie can actually recognise when you have been constantly dismissing notifications from the same app and will ask you if you want to mute them or allow them to keep displaying. This is a nifty little feature since most of us don’t want nonstop notifications from food ordering apps, travel apps and more. However, if you do want to bring back notifications from any app you have muted, you need to open Settings > App & notifications > Notifications. Here you can see how many alerts each app has sent and toggle the notifications on or off as you require.
Reset the Adaptative Battery feature
Android Pie uses machine learning for their Adaptative Battery feature which shuts down unused apps that are running in the background to preserve battery life. In case this feature picks up bad habits, you can reset the feature without having to wait to it to learn the right behaviour. Head over to Settings > System > Advanced > Reset Options > Erase all data. It is a nuclear option, but Google says it is the only way to wipe out everything the Adaptative Battery system has learned over time. However, it will begin learning fast again and enforcing battery-saving knowledge. Use this method as a last ditch effort since it is extreme.
Minimise the distraction your phone causes
In Android Pie, the Do Not Disturb mode has been beefed up quite a bit. Rather than just silencing incoming alerts, like it always has, it can also hide pop-up notifications. This way your phone will not light up at all and will not show anything in the status bar other than critical phone alerts such as battery low indicator. To configure this mode to your taste, you need to visit Settings > Sound > Do Not Disturb.
Take screenshots faster
While the old combination of volume down button and power button still works just fine, you can now use a new technique to take screenshots on Android Pie as well. All you need to do is hold down the Power button and tap Screenshot. This method has proven to be easier when users are taking screenshots with one hand. Additionally, you can also tap Edit on the notification of the screenshot and add text, drawing or more to it later.
Put limits on screen time
Google’s Digital Wellbeing tool is a brand new option which appears in Settings. If you’ve been spending too much time on Instagram or PUBG Mobile and figure out that you should cut that time down, you may not actually know how to get about it. The Digital Wellbeing Tool allows users to see which apps they’re spending excess time on, your total phone unlocks and total notifications for the day. You can set soft time limits on the apps you have been using excessively. They can be disabled again as well, which is counterproductive but at least it is something.
Use Wind Down to gently be pushed to sleep
Wind down is a nifty feature which uses a few tricks to gently push you into going off to sleep and not stay up using your phone. We have all been victims of using our phones excessively before sleeping which often leads to unhealthy sleeping patterns. Wind Down attempts to counteract this issue. You can set your bedtime and as the time approaches closer, your screen will be greyed out, the blue light filter will be turned on and Do Not Disturb will be enabled. All the changes are reversed when you wake up.
Keep your phone on with fingerprint sensor
As long as your phone has a traditional fingerprint sensor and not one of the new in-display fingerprint sensors, you can use this feature on Android Pie. Simply touching your finger to the sensor, even if it is for just a split second, the screen will keep itself from timing out and going dark. This is a trick that is lesser known, so you’re welcome in advance.
Turn off Hotspot directly when no devices are connected
This feature is usually on by default on Android Pie devices. Android 9 will turn off your Wi-Fi hotspot automatically if no devices are connected to it at that point in time, so you don’t have to worry about wasting power. In case the feature isn’t active on your Android Pie device, you can look at the Network and Internet section in Settings and select Hotspot and tethering > Wi-Fi Hotspot > Advanced. Then you need to make sure that the toggle next to ‘Turn off hotspot automatically’ is on.
Lockdown mode
Lockdown mode on Android Pie disables all Smart Lock and biometric security options and then will require you to enter a PIN, password or pattern to enter your home screen. The idea is to keep anyone from being able to force you to unlock your phone with your finger, face or another such method. To activate it, you will have to go to the Security sections in Settings, tap on Lock screen preferences and then activate Show lockdown option. If you need to use it, press and hold the power button and activate the ‘Lockdown’ command.
Find the Pie easter egg
Google has always been hiding a fun Easter egg inside its major Android releases, however, you need to know where to look to actually find it. Here’s how to do it on Android Pie. Go to Settings > System > About Phone > Android Version. Tap Android Version a few times and you will enter a screen which has a giant P that is surrounded by trippy animated circles. You can pinch the screen to resize these circles and you can change colours by pressing the back button.

Server - Advantages of creating a server

You’ve probably heard at some point that servers aren’t only for those that have a lot of money. In fact, anyone who has a spare box sitting around somewhere in their house can have their very own server, slaving away at whatever whims you may have. Although it sounds very cool, it does take some effort and a little know-how to get it all set up.

You can create your own server - Create Server

Note-you need a powerfull cpu to get a nice and powerfull server

So, before you get all sad and throw that spare box in the dump, here are five reasons why you should take the effort into making your own server.

1. You Control Your Data
If you’re an avid user of the Web, you probably have all kinds of information spread out over multiple servers and websites. For example, chances are you use Dropbox. Although it’s extremely convenient, your files are ultimately stored on their servers, so that means they control your data. You can protect yourself through different methods of encryption, but the storage location stays the same. You can change that by setting up your own server to hold your data. That way, what’s yours stays yours, and it will stay that way as long as you run your own server. With good security, other prying eyes won’t be able to see what you’re storing on your own server, so privacy is included.

2. You Build Your Own Services
make your own server
With your own server, you can do whatever you want with it. Run an email server to handle all your email (although saying goodbye to Gmail would probably be the hardest thing known to a geek), a proxy, FTP server, and many other combinations. You could even run your own version of Dropbox with enough help, or create your very own services that you may be in need of. The possibilities are endless, and you get to choose.

Sparkleshare - A Great Open Source Alternative To Dropbox [Linux & Mac]
There's been quite a few problems that have risen about Dropbox in recent months that is making some people feel uncomfortable about using it and are seeking refuge by means of an alternative.

3. No Surprises
Since you’re in control (this is pretty much the main idea), there won’t (or at least shouldn’t) be any surprises when it comes to your server. Aside from the small possibility of hardware failure, nothing in terms of the services that your server offers should suddenly change without you doing anything. While third party services may change the way their services or products work, yours won’t. You configure it to exactly how you want it, and then it stays that way until you change it again to meet your needs.

4. Have Fun With Your Server
make your own server
In the spirit of control and adding whatever you please, why not install some game servers in the meantime? There are so many different games such as Minecraft and Urban Terror that have software for servers that you can run to host your very own games. These games can have their own rules and customizations, making it even more fun for you and all your friends. Again, the possibilities are endless, and you can run as many different game servers as your RAM will hold and your CPU can handle.

We all know that there is no shortage of first person shooters, so we have to make our choice of which ones we want to play.

5. It’s Pretty Inexpensive
The costs of running a server are actually pretty insignificant, especially when you don’t need it at all times of the day. Your server will more than likely need to be connected to the Internet, but unless your regular Internet connection has major limitations that can’t let you successfully run your server on that connection, you can use the Internet connection that you’re using for your desktop or laptop right now. You can also get a free DNS name from a few different places like DynDNS if you don’t have a lot of needs for your server so that you can connect to your server without having to remember an IP address that might change occasionally.

The software should be free in most cases, and the operating system will more than likely be Linux (it’s recommended, anyways), so no costs will appear there. In the end, it’s really just the cost of electricity, which can be managed if say the server doesn’t have to be on while you’re asleep.

Conclusion
Running your own server brings many advantages that could make your life a lot easier and less stressful. After all the work in getting it set up, you can pride yourself in the fact that you have your very own server that you can do whatever you want with. In the end, it should be well worth it, with a spare box well used. If not, you can always check out this MakeUseOf guide to giving that old box new life.

How Electromagnets Work

What do a wrecking yard, a rock concert and your front door have in common? They each use electromagnets, devices that create a magnetic field through the application of electricity. Wrecking yards employ extremely powerful electromagnets to move heavy pieces of scrap metal or even entire cars from one place to another. Your favorite band uses electromagnets to amplify the sound coming out of its speakers. And when someone rings your doorbell, a tiny electromagnet pulls a metal clapper against a bell.
Mechanically, an electromagnet is pretty simple. It consists of a length of conductive wire, usually copper, wrapped around a piece of metal. LikeFrankenstein’s monster, this seems like little more than a loose collection of parts until electricity comes into the picture. But you don’t have to wait for a storm to bring an electromagnet to life. A current is introduced, either from a battery or another source of electricity, and flows through the wire. This creates a magnetic field around the coiled wire, magnetizing the metal as if it were a permanent magnet. Electromagnets are useful because you can turn the magnet on and off by completing or interrupting the circuit, respectively.Before we go too much farther, we should discuss how electromagnets differ from your run-of-the-mill "permanent" magnets, like the ones holding your Popsicle art to the fridge. As you know, magnets have two poles, "north" and "south," and attract things made of steel, iron or some combination thereof. Like poles repel and opposites attract (ah, the intersection of romance and physics). For example, if you have two bar magnets with their ends marked "north" and "south," the north end of one magnet will attract the south end of the other. On the other hand, the north end of one magnet will repel the north end of the other (and similarly, south will repel south). An electromagnet is the same way, except it is "temporary" -- the magnetic field only exists when electric current is flowing.

This is the simplest electromagnet.

The doorbell is a good example of how electromagnets can be used in applications where permanent magnets just wouldn’t make any sense. When a guest pushes the button on your front door, the electronic circuitry inside the door bell closes an electrical loop, meaning the circuit is completed and “turned on.” The closed circuit allows electricity to flow, creating a magnetic field and causing the clapper to become magnetized. The hardware of most doorbells consist of a metal bell and metal clapper that, when the magnetic charges causes them to clang together, you hear the chime inside and you can answer the door. The bell rings, the guest releases the button, the circuit opens and the doorbell stops its infernal ringing. This on-demand magnetism is what makes the electromagnet so useful.
In this article, we’ll take a closer look at electromagnets and discover how these devices take some pretty cool science and apply it to gizmos all around us that make our lives easier.

Cloud Forests

What Is A Tropical Montane Cloud Forest?

There is not an agreed upon definition of what makes a cloud forest a cloud forest. However, cloud forests are generally defined by their constant immersion in a layer of clouds. Here, we are interested in cloud forests that form along mountainsides (generally between 1,000 and 3,000 meters (3,300-9,850 feet), but as low as 500 meters (1,650 feet)) in the Tropics (between the latitudes 23°N and 23°S).

How Do The Clouds Form?

The process of forming clouds takes several steps. First, water evaporates off the sea or land surface, forming a warm mass of air. Next, the air mass is carried by winds until it strikes the side of the mountain. As the wind forces the mass of air and water vapor up the side of the mountain, it cools, and the water vapor begins to condense, forming water droplets that appear as clouds.

Where Do They Occur?

Tropical montane cloud forests are very rare and represent only a fraction of the world's remaining tropical forests. The best current estimate is only 0.14% of the entire land surface of the planet. In addition to Central America, tropical montane cloud forests are found in South America, Africa, Southeast Asia, and the Caribbean. There's even cloud forest on the side of Mt. Kilimanjaro in Tanzania.

Since they are almost always covered in clouds, tropical montane cloud forests have very unique climate conditions. This affects the plants and animals living in the forest and the ecosystem as a whole.

What Makes Them Special?

Tropical montane cloud forests are home to an incredible number of plant and animal species. In Monteverde, Costa Rica alone, there are approximately 750 tree species, and this number will likely grow as rare new species are discovered. In comparison, all of North America (north of Mexico) has approximately 1000 tree species. Many tropical montane cloud forests have high rates of endemism (species that don't occur anywhere else).

Why Are They A Conservation Priority?

These rare ecosystems are valuable for their beauty and biodiversity conservation, but they also have value to those living around them. They maintain water cycles, provide food sources, and are often attractive centers of tourism and thus provide people with their livelihoods.
Unfortunately, tropical montane cloud forests are threatened by a number of pressures. These include the cutting of forest for wood and cattle grazing, climate change, hunting, and tourism. As people need more and more resources to survive, the threats to these forests increase.
Climate change is among the biggest concerns in the tropical montane cloud forests. New research suggests that the timing, strength, and frequency of cloud cover is changing due to rising temperatures. These cloud cover changes have been associated with local extinctions and changes to populations of rare bird, frog, and salamander populations. New climate models suggest that in the next 50-100 years, cloud forests may get warmer and drier at rates that they have never before experienced.

Do flying fish really fly?

As the name flying fish heard we think of this
But it is actually this

so the question is do they fly.YES flying fish flies.There are about 50 species of flying fish. They are found in tropical and warm temperate oceans, moving into temperate seas with seasonal warming of water.
They are members of family exocoetidea and have large pectoral fins which spread wide and used as wings to glide once they break out the sea surface.
Flying fish can be seen jumping out of warm ocean waters worldwide. Their streamlined torpedo shape helps them gather enough underwater speed to break the surface, and their large, wing-like pectoral fins get them airborne.
Flying fish are thought to have evolved this remarkable gliding ability to escape predators, of which they have many. Their pursuers include mackerel, tuna, swordfish, marlin, and other larger fish. For their sustenance, flying fish feed on a variety of foods, including plankton.
Gliding Ability
The process of taking flight, or gliding, begins by gaining great velocity underwater, about 37 miles per hour. Angling upward, the four-winged flying fish breaks the surface and begins to taxi by rapidly beating its tail while it is still beneath the surface. It then takes to the air, sometimes reaching heights over 4 feet and gliding long distances, up to 655 feet. Once it nears the surface again, it can flap its tail and taxi without fully returning to the water. Capable of continuing its flight in such a manner, flying fish have been recorded stretching out their flights with consecutive glides spanning distances up to 1,312 feet.
Fishing
Flying fish are attracted to light, like a number of sea creatures, and fishermen take advantage of this with substantial results. Canoes, filled with enough water to sustain fish, but not enough to allow them to propel themselves out, are affixed with a luring light at night to capture flying fish by the dozens. There is currently no protection status on these animals.

CYBERCRIMINAL- Explained by DreTron Tech

A cybercriminal is an individual who commits cybercrimes, where he/she makes use of the computer either as a tool or as a target or as both.
#Subscribe my youtube channel-DreTron mods for some gameplay and technology videos.
Cybercriminals use computers in three broad ways:
  • Select computer as their target: These criminals attack other people's computers to perform malicious activities, such as spreading viruses, data theft, identity theft, etc.
  • Uses computer as their weapon: They use the computer to carry out "conventional crime", such as spam, fraud, illegal gambling, etc.
  • Uses computer as their accessory: They use the computer to save stolen or illegal data.
  • Cybercriminals explained by dretron tech
  • Cybercriminals often work in organized groups. Some cybercriminal roles are:
    • Programmers: Write code or programs used by cybercriminal organization
    • Distributors: Distribute and sell stolen data and goods from associated cybercriminals
    • IT experts: Maintain a cybercriminal organization's IT infrastructure, such as servers, encryption technologies and databases
    • Hackers: Exploit systems, applications and network vulnerabilities
    • Fraudsters: Create and deploy schemes like spam and phishing
    • System hosts and providers: Host sites and servers that possess illegal contents
    • Cashiers: Provide account names to cybercriminals and control drop accounts
    • Money mules: Manage bank account wire transfers
    • Tellers: Transfer and launder illegal money via digital and foreign exchange methods
    • Leaders: Often connected to big bosses of large criminal organizations. Assemble and direct cybercriminal teams, and usually lack technical knowledge.
    Clearly, there is much overlap between roles, but as cybercrime becomes a greater issue, more specialization is being seen as organized crime gets in the picture. For example, hackers were once more often than not hobbyists who broke into systems for personal gratification. While white-hat hacking hasn't disappeared, it's much more common now to see hackers as professionals who sell their services to the highest bidder.
