PHP Operator is a symbol i.e. used to perform operations on operands.
For example: $num=10+20;
PHP Operators can be categorized in following forms:
Arithmetic Operators
Bitwise Operators
Logical Operators
String Operators
Incrementing/Decrementing Operators
Array Operators
Assignment Operators
PHP Comments
PHP comments can be used to describe any line of code so that other developer can understand the code easily. It can also be used to hide any code.
PHP supports single line and multi line comments.
PHP Single Line Comments
// (C++ style single line comment)
# (Unix Shell style single line comment)
<?php
// this is C++ style single line comment
# this is Unix Shell style single line comment
echo "Welcome to PHP single line comments";
?>

Branching / Decision Making Statements
The statements in the program that helps to transfer the control from one part to other parts of the program.
Facilitates program in determining the flow of control
Involves decision making conditions
See whether the condition is satisfied or not
If statement; Execute a set of command line or one command line when the logical condition is true.
It has only one option
syntax with flowchart
If else if ladder; Number of logical statements are checked for executing various statement
If the first condition is true the compiler executes the block followed by first if condition.
If false it skips the block and checks for the next logical condition followed by else if.
Process is continued until a true condition is occurred or an else condition is satisfied.
Switch case; Multiway branch statement
It only requires one argument of any type, which is checked with number of cases.
If the value matches with the case constant, that particular case constant is executed. If not the default statement is executed.
Break statement – used to exit from current case structure
Nested if else; When a series of decisions are involved we use more than one if-else statement.
If condition is true control passes to first block i.e., if block. In this case there may be one more if block.
If condition is false control passes to else block. There we may have one more if block.
The lazy programmer's guide to writing thousands of testsScott Wlaschin
We are all familiar with example-based testing, as typified by TDD and BDD, where each test is hand-crafted.
But there's another approach to writing tests. In the "property-based testing" approach, a single test is run hundreds of times with randomly generated inputs. Property-based testing is a great way to find edge cases, and also helps you to understand and document the behavior of your code under all conditions.
This talk will introduce property-based testing, show you how it works, and demonstrate why you should consider adding this powerful technique to your toolbelt.

Fwdays вединар: Node.js in 2020: Выйди и зайди нормально - Часть 1
Видео: https://youtu.be/GJY2dyE6328?t=480
За последние 5 лет Node.js очень изменился, но знания о платформе у сообщества остались на уровне 2013-2015 годов, все те же подходы, все те же проблемы. Сообщество плохо следит за новыми возможности, а если и узнает про них, то это не влияет на написание ежедневного кода. В Node.js, да и в JavaScript, слабо проникают фундаментальные знания по программной инженерии и архитектуре, параллельному программированию, GRASP, SOLID, GoF, а если и проникают, то не подвергаются адаптации и переосмыслению. Поэтому, среди других языков программирования JavaScript воспринимается, как несерьезный, а Node.js, как платформа для малограмотных людей. Как преодолеть эту тенденцию и как изменить подход к разработке на Node.js в 2020 году, с использованием всех современных возможностей и знаний, а так же, что нужно изменить в ежедневных практиках написания кода, эти и другие вопросы будут освещены в докладе «Node.js в 2020: Выйди и зайди нормально».
A reworking of my 2010 RubyConf lightning talk introducing Go via a concurrent implementation of MapReduce. This code is probably buggy as hell and the design awful but it's also a reasonably good intro to the full breadth of Go.

In addition to blocking CPU-bound tasks, we can use worker_threads to run asynchronous non-blocking domain logic if our main event loop is already overloaded. Now we have perf_hooks API which can be used to create load balancer to spread load in worker pool to provide the most dense event loop utilization. Mentioned machinery can be encapsulated in a simple abstraction with async/await contract to have a solution competing with goroutines in Go for both convenience and efficiency.

If Node.js is your everyday tool, it's almost certain that you use it in the wrong way, Timur will prove that in a very short review, uncover anti-patterns in your daily standard solutions, and show you the way to much better practices. The only thing that creates obstacles in your way to knowledge is your laziness.
Low-code sells great, but in practice, it does not provide the benefits that vendors have claimed. What are the reasons and how can we get an advantage using the Low-code principle? Experience of radical rethinking and use-cases in enterprise applications together with multi-paradigm programming and metaprogramming.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
