So many useful tools have been upgraded, like the wallet, and the access to so many things are at your wrist. You even need not take your iPhone out of your pocket. In addition, this Update comes with nearby smart devices. Well, it'd be better if we discuss all these things in detail.

We have covered all the new updates you get in your wrist after OS 8 Update, and your doubts in this article will be clear. So, let's break the ice and determine the benefits of this new watchOS 8 Update without any further due.

Release Date of WatchOS 8

It is expected that this version update will be officially launched with the new Apple Watch 7 and iPhone 13 in September. If you create a developer account or you've, you can easily access the beta version, and the public one will be launched in July.

What's in New WatchOS 8?

Apple has bought a bunch of new features in their latest software update. Let's go through all the exciting updates!

• More Access With Wallet

After syncing with the new iOS15, you will have complete control over all the digital keys you have for the office, home, hotel etc. Just by using your watch, you would make the payments on the shops. In fact, till the end of this year, US users will be able to attach their Driver's License or State ID to the wallet.

• Redesigned Home App

Whenever there is any smart device in your range, you will get automatic suggestions such as unlocking the door or turning off the lights. You can even control the CCTV just with the help of the watch OS 8 on your wrist.

• New Workout Types

This Update has bought two new kinds of workouts - Tai Chi Vs. Pilates. These exercises are so relaxing for the mind and physique.

• New Approach to Mindfulness

Yoga has brought a complete change in the thought process of today's world. Now people are eager to find that one moment where they can be mindful. And for this, Apple has contributed through their new breathe app, Reflect. This takes a small session of only 1 min. With each passing session, you enter into a completely different frame of mind.

• Sleeping Respiratory Rate

People are busy and don't have a good sleeping cycle. Here Apple helps users set a pre-bedtime, and during the whole sleep, it monitors your sleeping respiratory rate. Apple Watch has an accelerometer to this rate.

• Portraits Watch Face and Photos

Now, after this Update, your apple watch will have the portrait mode that the iPhone has. You will even be able to share the photos via messages and mail without taking your iPhone out of your pocket.

• Message and Contacts

We've already discussed the above paragraph; you will even send messages through just your watch. But, of course, you'll have emojis and GIFs, too and will also be able to correct the errors with the help of a digital crown.

• Focus

This feature will help you to remove all the distractions while you're doing something important. You will have several features like Do not disturb, fitness, work and sleep. You can even sync with the customer focus according to your requirement. When someone tries to contact you, you'll get a notification that you're in "Focus Time."

Watch OS 8 Supported devices.

After the Apple Watch 3, update OS 8 is compatible with each device. So all you need to have is at least an iPhone 6s with the latest iOS 15. Exact requirements are valid for the developer and beta version as well.

What is PHP? - Mono-live

What is PHP?

It is the short- form of Hypertext Pre-processor.

It is a popular scripting language and open-sourced. It is apt for web development and comes embedded in HTML.

It comes in handy as they can manage

• Session tracking 
• Databases 
• Dynamic content
• Build e-commerce sites

Also, this language integrates well with a few databases, such as

• Oracle 
• PostgreSQL 
• MySQL 
• Informix 
• Microsoft SQL Server and 
• Sybase.

A Brief History:

It was Rasmus Lerdorf, the Danish- Canadian programmer who inspired it in the year 1994.

Even though the earlier but unreleased versions existed, Rasmus used them for his purpose. He kept track of those who used to visit and read his online resume.

In 1995, the first version was released, and it was called 'Personal Home Page Tools. ' The first version had a simple parser engine that could make sense of a few macros along with several utilities. These utilities were quite common on Home pages way back in 1995.

In Mid 1995, yet another version named PHP/ F1 Version 2 with a freshly written parser was released and would consist of a

• Guestbook 
• And a counter.

Rasmus combined the F1, which he was using in another package, with this, and with that, Html data could be interpreted.

It required mSQL to add to the existing combination of Personal Home Page and the form Interpreter to give PHP/ F1 its birth.

Over fifty thousand users existed in 1997, and it was time for a change.

The project to develop it was now entrusted with a team, and two people named Andi Gutmans and Zeev Suraski found a new parser that was written from scratch. This was called PHP version 3. To make it more effective and complete, utility codes from PHP/ FI were transferred and rewritten completely.

Scripting Language:

It is a programming language and automatically executes tasks during system runtime.

Difference between Scripting & Programming language:

• Scripting language does not require compilation step as they can be interpreted. 
• C programming requires compilation wherein scripting language need not. 
• Scripting programs run faster compared to the other. 
• Programming languages are used traditionally with compilation step that could be C, C++ whereas scripting language explicit step of compilation is VB Script, JavaScript and PHP.

• Importance of it-Web Development and PHP- An ideal combination.

Here are some features that reflect how vital PHP is in web development.

• Performance:

No user has the patience to wait for more than a few seconds for the site to load fully. So the question is how to keep the user engaged in these precious moments? Luckily, it has the feature 'JIT,' which accelerates compiling its code to machine language and enhancing the results.

• Compatibility:

It works like silk with the best of OS, web servers, and databases. The option of choosing the database is, of course, the users, but it would undoubtedly work in most of them.

• Flexibility:

It is known to be a highly flexible web programming language. Additions and deletions of new features and old features are possible even after the code has been written and completed.

• Scalability:

One area where it has been in use predominantly is the websites that experience high traffic all the time. With this added advantage, web developers have the confidence to develop websites or web applications at the best range possible.

the code can be embedded into HTML on simple websites. This can be expanded for the construction of web applications that are large-sized and complex as it does have in it the requisite tools and resources to do so and in a shorter period.

• Open Source:

Businesses that range from small to large-sized prefer open-sourced technologies as it helps curb the project overheads. There is no requirement to pay a fee as far as the licensing is concerned.

Uses of PHP:

• Dynamic websites can be created 
• Makes it possible for the webserver 
• Back-end interacting and data servers are made easier 
• Data encryption is possible 
• Business logical layers can be implemented. 
• The OS and the native file layers can interact 
• Cookies, whether variable or set, can be accessed. 
• Handy in sending and receiving emails 
• Web applications and Databases can be connected 
• You can build a calendar using it.

PHP Extensions:

The library that is specifically formed or a plug-in with at least one function that can be used in more than one application requires a PHP Extension.

The main advantage of Extensions is that time can be saved by not allowing the recreation of the existing codes.

Just connect it to the PHP binary applications for use.

Installation and implementation of it:

•  Make sure XAMPP is installed to install it, Apache, etc., in a single attempt.

Next, go to XAMPP in Windows and wait for it to download.

PHP Security:

Popularity and large-scale use do make it vulnerable. In addition to that, all the applications using it also become equally threatened.

Reasons for vulnerability:

• Bad coding practices 
• Lack of awareness 
• Not using two writing procedures while writing the codes, namely Sanitization and validation. 
• Ensure Object-oriented programming for better security. 
• Not using a reusable code that is well written.

Conclusion:

There is no doubt that PHP programmers have to utilize time and utmost skill to write a web application in it.

Resources and time utilization are essential for its successful implementation. With that done, the output can only be successful.

Sparkplug— JavaScript Compiler Makes Chrome Faster

Recently Google has launched Chrome 91, the latest version of its browser, and modified with advanced features and additions. The new version is accompanied by the ability to freeze Tab Groups and possess PWAs on startup. Moreover, Chrome 91 is 23% faster because of a pair of JavaScript compiler additions. By employing a new compiler called Sparkplug and short builtins calls, it’s saved over 17 years of users’ CPU time each day.

The new Compiler Provides Stability 

The new compilation system is an excellent supplement to the JavaScript pipeline, as it serves as an intermediary between the current Ignition and Turbofan. Ignition interprets the bytecode, and Turbofan optimizes the high-performance machine code. Both do a solid job. However, it takes time to prepare and optimize all the code.

It combines a different compiler and strikes stability between the two in that it generates native machine code but doesn’t depend on information learned while executing the JS code. It bridges the gap between starting to implement code quickly and optimizing it for maximum execution.

The brand-new compilation system stabilizes the engine’s two-tier method. It produces machine code without relying on the data accumulated during the accomplishment of JS code. This enables Google Chrome to “generate relatively fast code and start running quickly,” Google states.

Whereas, Short builtins calls, on the other hand, optimize the space Google places. Code produced to withdraw indirect jumps when “calling a function.” In addition, Google Chrome’s V8 engine is supplement by various compilers that make several trade-offs at distinct levels of administering JavaScript.

Sparkplug is Speedy

The new compilation system is designed to compile fast. It is so speedy that we can pretty much collect whenever we want, allowing us to tier up to Sparkplug code much more aggressively than we can to TurboFan code.

There are a couple of tricks that make the compilation fast. First of all, it cheats; the functions that it compiles have already been collected to bytecode. The bytecode has already done most of the hard work like variable resolution, figuring out if parentheses are arrow functions, desugaring destructuring statements, and so on. It compiles from bytecode rather than JavaScript source, and so doesn’t have to worry about any of that.

The second method doesn’t produce any intermediate representation (IR) like many compilation systems perform. Instead, it compiles straight to machine code in a single linear pass over the bytecode, emitting code that meets the performance of that bytecode.

Differ to Builtins

Sparkplug hardly produces its codes. JS semantics are intricate and extract several codes to function for even minute operations. However, propelling it to reproduce this code inline on each compilation would be bad for varied reasons. Firstly, It would improve compiling from the absolute amount of code required to produce.

Secondly, It would enhance the memory consumption of compilation code. Lastly, it has to Re-implement the code-gen for a group of JavaScript functionality for it, which means more bugs and a more prominent security surface.

Therefore, instead of all this, many compilation codes call into “builtins,” small snippets of machine code installed in the binary to do the actual messy task. These builtins are either the identical ones that the interpreter practices or distributes most of their code with the interpreter’s bytecode handlers.

Consequently, V8 has an advanced super-fast non-optimizing compilation system, which enhances and boosts the performance of the V8.
