Suggested January 2024 All Android Smartphones Will Soon Be Able To Connect To Satellites

You can communicate from anywhere in the world if you can see even a small patch of sky. Francesco Grilli, the Qualcomm vice president in charge of satellite technologies, has made this commitment. He demonstrated how this technology would soon be available in Android smartphones at CES 2023. Thereby responding to Apple. Which in September 2023 with the release of its iPhone 14 launched the era of emergency satellite communication.

If Qualcomm trails Apple in the race, it is primarily due to Qualcomm’s later debut date for processors. Qualcomm typically introduces its SoCs at the end of the year. However, Qualcomm’s “delay” primarily pertains to the software rollout and launch of the services. The vast majority of high end Android devices this year that incorporate Snapdragon 8 Gen 2 CPUs are already compatible. But the choice of the satellite partner sets Qualcomm’s technology apart from Apple’s in a significant way.

The satellites connection of Android smartphones will be much better than iPhone

In contrast to Apple, who contracted with Globalsat, Qualcomm turned to American Iridium, another satellite expert. Who is unquestionably the field’s heavyweight in the industry. Most people who work in fields that need them to think creatively outside the box, such as mountaineers, humanitarians, explorers, journalists covering armed conflicts, and government officials, are likely to have a satellite phone. It is often an Iridium-based device because of this network’s main strength: its global reach.

A device compatible with the Iridium network can successfully send and receive messages from the North Pole to Point Nemo in the Pacific Ocean as soon as a patch of sky is available – bidirectionality which will also be on the agenda with smartphones. The Globalsat network is not like that. The two networks’ technical architecture is to blame for this. Iridium is a constellation with inter satellite communications. Whereas Globalsat relies on ground relays (there are several dozen on the earth).

Sattelite connection will be available for all Qualcomm smartphones

Gizchina News of the week Strengths of Apple: integration and investments

As we’ve seen, Globalstar does not provide the same level of comprehensive coverage as Iridium. The network is secondly dependent on a small number of ground stations. Because the satellite industry, which includes Iridium, Inmarsat, Globalstar, and Thuraya, is small and doesn’t produce much revenue. Without the “debauchery” side that an actor like Space X can portray, all launches are controlled. Apple is completely aware of everything. Without a doubt, this is the reason the American giant has chosen to improve the network. By digging further into its pockets.

Therefore, since the release of the iPhone 14, Apple has been quite insistent in its marketing about the feature. To discuss its investment in the system. Thus, the Americans will invest 450 million dollars over the course of five years to strengthen the ground station network. In the beginning in the states of Hawaii, Alaska, Florida, Nevada, or Puerto Rico in the United States (first market where the service was deployed). Since so few people actually require Iridium’s global coverage, many American states continue to be sparsely populated, untamed, and occasionally lacking in adequate network infrastructure. Thus, it appears that Apple’s answer is already appropriate for a larger audience.

Last but not least, Apple will also stand out on the integration side. Because the service is (as usual with Apple! ), planned out from A to Z. The ease of signing up for a protection plan when the time comes. Right now it’s free for two years, and time will tell what Apple has chosen, etc. Pre-recorded messages in the terminal (which automatically encompass GPS position) to software integration, etc. The American has everything set up already.

Qualcomm’s Android partners will need to start from scratch to develop not only a software offer. But also a technical and commercial offer that is tailored to each country. Where the devices are sold if they want to compete with Apple. The Achilles heel of Android devices is typically their finishes. Hope Qualcomm has already set the stage for its partners; if not. It will likely be necessary to wait a little while for its solution. Which is superior in terms of space, to truly challenge Apple’s.

8 Most Iconic Chinese Smartphones Of All Time!

Meizu M8

Launched at around the same time as the original iPhone and with a similar design, it is easy to see why some journalists were quick to tag the Meizu M8 as a clone, a label we really don’t believe the M8 deserved.

The Meizu M8 ran a highly modified version of Window’s CE mobile OS which was transformed to look more like the iOS inspired Android themes we are used to seeing. The display measured 3.4-inch which a resolution of 720 x 480, there were options of either 8-16GB of internal memory and a 667mhz Samsung ARM11 CPU ran things.

Oppo A121

One of the earliest Oppo smartphones is the Oppo A121, aka the “small phone” due to the cute smiling design on the rear which hid the rear camera in one of the ‘eye’s of the phone.

Oppo developed their own OS for the A121 based on Java which allowed additional apps to be installed, although not many were made available. Specifications included a 2.4-inch 240 x 320 display, physical keyboard, 2 mega-pixel camera and 900mhz battery.

Vivo X1

BBK, the company behind the Vivo brand (and the company which kick started Oppo) have a great following here in China, but it wasn’t until 2012 when international phone fans sat up and took notice of the rising smartphone star.

In 2012 Vivo launched the then world’s thinest Android smartphone (beating the Oppo Finder by just a hair). The 6.65mm Vivo X1 shocked the world for not only becoming the thinnest smartphone, but for its high-end specifications, and the quality of materials it was manufactured from.

In the 6.65mm alloy body of the Vivo X1 they had managed to cram in a 2000mAh battery, Cirrus Logic CS4398 digital analog converter, CS8422 sample-rate convertor for audio, dual-core Mediatek MT6577T processor, 1GB RAM and 8 mega-pixel main camera.

The Vivo X1 remained in production as the Vivo X1S which received dual-SIM support and a more powerful quad-core processor.

JiaYu G3

The JiaYu G3 can remembered for a number of reasons. It was one of the best looking and highly spec’d Chinese smartphones available of 2012 and it also suffered from the most delays of any Chinese Android smarpthone to date and was the phone that catapulted JiaYu in to the heart and minds of customers around the world.

The JiaYu G3 was, and still is, a great looking phone with a similar design to modern Blackberry devices. The front of the phone was made of a brushed alloy material available in silver or black, while the was removable to get at the battery.

JiaYu originally launched the JiaYu G3 as a 1.2Ghz dual-core smartphone using the Mediatek MT6577 chipset with 1GB RAM. The phone also boasted a 1280 x 720 display, 8 mega-pixel rear camera, and dust just 999 Yuan ($160). The JiaYu G3 didn’t go out of production until last year, in it’s finally months of manufacture the G3 received an updated quad-core processor.

Newman N1

2012 was also the year digital audio manufacturer Newman decided to take the leap from making MP3 and MP3 players and start to produce Android smartphones. The first smartphone produced by Newman was sold as the Newman N1 in China and abroad, but international customers could also pick up the Freelander i10 which was basically the same phone.

Like phones produced at the same time as the Newman N1, the phone came with a dual-core MT6577 chipset, 1GB RAM, 8 mega-pixel rear camera and Gorilla Glass display.

The N1 was only in limited production and continued to sell out so fast that many customers at home and abroad were never able to get their hands on the first generation Newman phone.

Since then Newman have continued to make new smartphones, however more recent phones have struggled to receive the same scale of excitement that the earlier N1 and later N2 were able to achieve.

Xiaomi M1

2012 was a great year for Chinese smartphone makers, and for companies wanting to diversify and include smartphones in to their range, but why? There are a number of possible reasons but we believe the launch of the original Xiaomi M1 in 2011, was the major factor which shook the Chinese phone scene.

At a time where most people looked down on the idea of a Chinese smartphone, one plucky team of investors decided that a Chinese phone with high-end hardware and a low-cost is exactly what the world needed.

In August of 2011 Xiaomi first made headlines with the launch of it’s first phone, the Xiaomi M1. The M1 blew away everything we had come to expect from a phone costing just $300. It packed a powerful Snadpragon dual-core processor, 1GB RAM and a large 4-inch display.

Ever year since the M1 launched, Xiaomi have launched new models at the same 1999 Yuan price point but have continued to improve the hardware, design and the MIUI OS.

Meizu M9

Meizu released its first Android phone in 2010. The Meizu M9 was an affordable device with great hardware, and actually the first Chinese Android smartphone I owned.

Meizu hoped that the M9 would be able to compete with the iPhone 4 which officially launched in China at around the same time. Both the M9 and iPhone 4 saw huge crowds, limited supply and were often compared to one another during reviews.

Other specification highlights included a 5 mega-pixel rear camera, removable battery and 3.5-inch Sharp AVS 960 x 540 display. Meizu game Android 2.2 a full make over to create their own OS which eventually became Flyme in later updates.

Although the Meizu M9 had a great specification it suffered from a number of issues including overheating, poor battery life, and app compatibility, details which were finally sorted by the time the first MX phones went on sale.

Oppo Find

The Oppo Find was the first and only Oppo device with a slide out Qwerty keyboard and 3.9-inch touch screen. The body was manufactured for alloy and specs included a 1Ghz Qualcomm Snapdragon MSM8255 CPU, 512mb RAM, 8 mega-pixel camera and their companies own Oppo NearMe app store and tweak Android OS.

Honrable mentions

Phones which were also considered for the list were the:

Oppo Finder.

GooPhone i5.

Nubia Z5.

Vivo Xplay.

Zopo ZP998.

Xiaomi Hongmi.

Will Linux Emit Event When Monitor Connect With D

Introduction

Linux is an open-source operating system that is popular among developers and system administrators. It is known for its flexibility, reliability, and security features. One of features that make Linux stand out from other operating systems is its ability to interact with various hardware components seamlessly. In this article, we will discuss whether Linux emits events when a monitor is connected with a D-sub connector. We will explore various methods that can be used to detect and manage connection of monitors to Linux-based systems.

What is D-sub connector?

Before we dive into details of how Linux interacts with monitors connected with D-sub connectors, let us first understand what a D-sub connector is. A D-sub connector is a type of electrical connector commonly used for video signals. It is named after its D-shaped metal shell that provides mechanical support, electromagnetic shielding, and grounding. D-sub connectors come in various sizes and pin configurations, depending on their application.

Does Linux emit events when a monitor is connected with a D-sub connector?

The short answer to this question is yes. Linux does emit events when a monitor is connected with a D-sub connector. However, events that are emitted may vary depending on version of Linux and desktop environment being used.

In Linux, when a monitor is connected or disconnected, system generates a corresponding event. These events are called “hotplug events” or “plug and play events.” hotplug events are used to detect and manage connection of various hardware components to Linux-based system, including monitors connected with D-sub connectors.

Detecting monitor connection with udev

udev is a Linux subsystem that manages device nodes in /dev directory. It is responsible for detecting and configuring hardware devices as they are plugged into system. udev can also be used to detect connection of monitors to system.

To detect connection of a monitor with a D-sub connector, you can use following udev rule −

ACTION=="change", SUBSYSTEM=="drm", ENV{HOTPLUG}=="1", RUN+="/path/to/your/script.sh"

This rule will trigger execution of chúng tôi file when a monitor is connected or disconnected from system. chúng tôi file can contain commands to perform various actions, such as configuring monitor’s display settings or adjusting system’s resolution.

Detecting monitor connection with xrandr

xrandr is a Linux command-line tool that can be used to detect and manage connection of monitors to system. It provides an interface to X RandR (X Resize and Rotate) extension, which allows for dynamic configuration of screen layout, resolution, and orientation.

To detect connection of a monitor with a D-sub connector using xrandr, you can use following command −

This command will return a non-zero exit code if a monitor is connected to VGA-0 port. You can then use conditional statements in your script to perform actions based on exit code.

Managing monitor connection with xrandr

Once a monitor is detected using xrandr, you can use same tool to manage its connection. For example, you can use xrandr to adjust resolution, orientation, and screen layout of connected monitor.

To change resolution of a connected monitor, you can use following command −

xrandr --output VGA-0 --mode 1280x1024

This command sets resolution of monitor connected to VGA-0 port to 1280×1024. You can change mode to any supported resolution of connected monitor.

Other desktop environments such as KDE and Xfce also provide their own tools for managing monitor connections. These tools can be customized to fit specific needs of your Linux-based system and provide a seamless and intuitive user experience.

In addition to tools provided by desktop environment, there are also third-party tools and applications available for managing monitor connections in Linux-based systems. For example, arandr application provides a graphical interface for managing monitor connections using xrandr. It allows you to easily configure screen layout, resolution, and orientation of connected monitors using a drag-and-drop interface.

Conclusion

In conclusion, Linux does emit events when a monitor is connected with a D-sub connector, and there are several ways to detect and manage connection using tools such as udev and xrandr. These tools provide a flexible and convenient way to manage display settings of monitors connected to Linux-based systems.

It is worth noting that specific events that are emitted and methods used to manage connection may vary depending on version of Linux and desktop environment being used. Therefore, it is important to consult documentation for your specific Linux distribution and desktop environment to determine best approach for detecting and managing monitor connections.

7 Big Battery Android Smartphones For Mid 2023

UMi eMax

Compared to some phones on the list the UMi eMax has quite a dainty battery size of just 3780mAh, but UMi believe this is enough for the phone to give at least 2 days of battery life on a single charge.

It’s not just the battery size of the UMi eMax which is a selling point either though. The phone is a pretty well rounded handset with attractive design, powerful MT6752 chipset, 5.5-inch FHD display and 13 mega-pixel camera. Pricing is very competitive too at just $159.99.

[ UMi ]

Elephone P8000

A 7.2mm metal chassis sounds as though it will be comfy in the hand, surprising too as the claimed battery size of the Elephone P8000 is a 4165mAh battery. Elephone say this is enough for 269 hours of stand by, 21 hours of call time, 30 hours of music and 16 hours of gaming. The Elephone P8000 is due to launch at the end of July for around $209.99.

[ Elephone ]

Gionee M5

The full details of the Gionee M5 are still underwraps as the phone won’t be officially released until the 10th June, still we do know it’s battery size and it is simply massive. The Gionee M5 will actually incorporate dual batteries in the phone for a combined 6000mAh!

Other specs of the phone (to be confirmed) are a 5.5-inch AMOLED display, 1.3Ghz processor, 2GB RAM, 8 megapixel main camera and 5 mega-pixel front. The phone is also said to measure in at only 8.6mm!

Bluboo X550

At $169.99 the Bluboo X55 is slightly more expensive than the UMi eMax, but the extra money goes in to providing an even larger battery. The phone is on presale now, and those of you who manage to get your hands on the phone will enjoy a 5300mAh battery, 5.5-inch OGS display, fast charging, Android 5.1 and 2GB RAM.

[ Bluboo ]

Innos D6000

Innos have also gone down the 6000mAh battery route with the Innos D6000, but rather than 2 cells the D6000 uses a single large battery. The Chinese phone maker has also given their device a Snapdragon 600 processor, 5.2-inch 1080 display, 2GB RAM and even a 16 mega-pixel main camera!

Siswoo C55

Siswoo are on a roll and the Siswoo C55 appears to be the phone that could really put them on the map. Amazingly the stylish Siswoo C55 has a huge 4200mAh battery, a fact that is even more amazing when you realise the phone costs just 119 Euros! The handset will also have a 5.5-inch HD display, 8 mega-pixel rear camera, MT6735 chipset and 2GB RAM. Not a bad set-up for the money.

[ Siswoo ]

Mlais MX Base

Originally known as the Mlais MX, the phone is now called the MX Base and will ship with the same hardware originally promised. Those hardware specifications include an MT6735 chipset, the same as found in the Meizu m2 note, 5-inch HD display, 2GB RAM and 13 mega-pixel rear camera. On the battery the Mlais MX Base boasts a 4800mAh battery behind a green, white or black rear cover.

[ Mlais ]

Those are just a few Android phones with large batteries for the middle of the year, but as the trend continues expect more large battery handsets to launch and the average battery size in our phones to increase!

How To Connect Database To Php?

Introduction to How to Connect Database to PHP

To make optimum usage of any database, one should be able to manipulate it as required. The best way to manipulate and manage the databases you created is to connect your database with PHP. First, let us understand what PHP is. PHP is like a control panel that can be used to manage your database. Connecting to PHP allows you to retrieve data from databases as needed for a particular query. MySQL is the most popular open-source RDBMS, which can be easily connected to PHP. MySQL organizes data in tables using a row and column structure. As a result, MySQL is suitable for both small and large applications, and it operates on the server.

How to Create a Database?

Creating a database in MySQL is as simple as performing a single command in SQL. For example, an easy query of “[CREATE DATABASE]” can be used for database creation for beginners. Another database creation option is using another query as “[CREATE SCHEMA].”

Adding more parameters and avoiding confusion between existing databases on a single MySQL server can use the command “[IF NOT EXISTS].” This query checks whether any existing database has the same name. If yes, the command will not execute the creation of the database. On the other hand, if there is no such conflict of database names, the below command will execute and create a database. Although “[IF NOT EXISTS]” is non-mandatory, it is a good practice.

This newly created database will be empty, waiting for the inclusion of tables with data. SQL command for tables is a simple query “[CREATE TABLE]” with syntax as below.

Connecting Database to PHP

PHP versions below 5 use MySQL extension. But this extension was derogated in 2012.

The 5th version of PHP and newer versions can work with below:

1. MySQLi extension

2. PDO (PHP Data Objects)

According to their own supremacy and needs, any of the above options can be utilized.

The MySQLi extension can be used only with MySQL databases, whereas PDO can connect with 12 different database systems. So, PDO might be helpful if one is switching databases as it only requires changing a few connections. But in the case of MySQLi, we need to write the entire code and query to switch databases. Enabling MySQLi on PHP is necessary to work with MySQLi. MySQLi also provides a procedural programming interface along with an object-oriented one. PDO and MySQLi support prepared statements, which are crucial aspects of web security.

Working with PHP and MySQL

PHP and MySQL are some of the most common stacks for web development.

Object-oriented MySQLi

Procedural MySQLi

PDO

To start with any of these, you must know some essential details, such as your database system’s server address, username, database name, and password. Mainly, we will be using mysqli_connect in all three procedures. This command sets up a connection between the database and PHP. First of all, we have to create a separate connection file. This saves time in writing code every time you want to insert data and information from the database and insert this data in multiple files.

Let’s look into each of them one by one:

1. Using Object-Oriented MySQLi

This can be used to build an association with the database using PHP script using the following syntax.

Explanation:

Localhost is the location of the server. The host can be something else, but the server runs on the localhost in most cases.

The username is the root, and the password; is the same which you use for php admin.

To establish this link, provide the necessary details such as localhost, username, and password. This will create an instance of MySQLi, resulting in a successful connection.

2. Using MySQLi Procedural

To establish a connection between the database and PHP using MySQLi procedural, you can follow the procedure outlined below:

Explanation:

The main difference for the procedural procedure is that it uses the function mysqli_connect, which fetches the necessary details of the host, username, and password, etc. When successfully connected, it will provide a link identifier.

3. Using PDO

PDO represents PHP Data objects. So in this process of creating a connection, PHP data objects are used as below:

The exception function in PDO assists in throwing and handling any exceptions that may arise while establishing connections, ensuring proper management of any encountered issues.

All the above methods help access and manage the database you need.

Checking the Connection:

Below syntax can be used to check whether your connection is successfully connected.

Db_connection is the php file name.

Ending the Connection:

Once you establish a database connection using PHP scripts, you should close the connection once your work is finished. With an assumption of reference to the connection stored in the $ conn variable, below are the closing syntax used in the above-given procedures.

Using MySQLi object-oriented procedure

Using MySQLi procedural procedure

Using PDO procedure

Conclusion – How to Connect Database to PHP?

Accessing and managing your database becomes straightforward when you establish a connection using PHP. It also offers a variety of ways to establish this connection to suit varying levels of requirements. After establishing the connection, you can actively execute queries to extract data from the tables. You can easily print out this information. Closing the connection is an essential part of connecting the database to PHP, and it should be done once your work is completed.
