      Respect elders and loves from children. Whoever sees evil in his ruler, let him be patient. Allah does not like lies at all so lies should be avoided. Bow down because even the prophets used to bow down, Allah does not like arrogance at all. When you talk smiling, smiling is also charity. Help the poor, give zakat. This is the command of Allah. Feed the orphans; put your hand of compassion on their heads. Obedience to Allah is also included in removing any problem from the path or clearing the path. Whoever obeys the Prophet (s.a.w) obeys Allah, so let us follow the Sunnah and Hadith of the Prophet (s.a.w).

    • 5 Tips Super Simple for Sustaining Strong Immune Systems

      Tahera Irum

      Your health is one of the most valuable things you have — if not the most important. Today more than ever, people across the world are practicing gratitude for health while being vigilant about protecting it. Pandemics and viruses aside, there are ways to give your health the right priority it needs no matter what age you are.

      Strong immunity, while crucial to preventing and fighting illness, is also a key component to living a balanced, happy life. How? The habits and practices you can do to support your immunity all lend themselves to a happy, holistic existence. It’s the best of both worlds; being strong and healthy to combat disease and illness and enjoying your body for the life it’s given you.

      What Does “Strong Immune System” Mean?
      Your immune system is exactly that, a system. The human body is made up of 11 separate systems that do their independent parts to keep your body running at its most optimal.

      The primary purpose of your immune system is to protect against pesky, persistent bacteria that want nothing more than to attack your body, breaking it down to make it more susceptible to injury and illness. Your immune system is the gatekeeper for what gets in and what stays out of your body. When it is working, the viruses and toxins don’t have a chance. When it’s not, the floodgates are wide open.

      Your body shows signs of a strong immune system pretty often. One example is when you get a mosquito bite. The red, bumpy itch is a sign of your immune system at work. The flu or a cold is a typical example of your body failing to stop the germs/bacteria before they get in. However, when you recover from the cold or flu, it’s proof that your immune system was able to eliminate the invader after learning about it and reacting to its defense. If your immune system did nothing, you would never get over the cold, or anything else for that matter. When you are sick, your body isn’t able to perform at its full potential.

      Depending on the nature of what’s got you under the weather, a prescription or over-the-counter medication may be needed if your immune system isn’t reacting or responding quickly enough. That too is normal; antibiotics were created for this very reason. The good news is there are many things you can do to keep your immune system strong and healthy.

      How To Boost Immunity
      Living a healthy lifestyle is your single best option to a strong immune system. Every part of your body functions better when it is fueled with healthy foods, a positive environment, and minimal stress. Sound ideal? Here are some easy tips for a stronger immune system that won’t overwhelm you.

      Daily Exercise

      Yes, daily. Just 30 minutes.

      There are numerous benefits to exercise, including prevention of arthritis, diabetes, heart conditions, and more. Exercise has also been shown to enhance and improve different components of the immune system. Exercise also improves your sleep quality and increases immune function. Go for a walk, become a member of a fitness center, find some fun exercises, and commit to a routine. Exercise also doubles as a mood and mental booster — two benefits in one.

      Let the Light In
      Enjoy moderate exposure to sunlight a few times each week. Vitamin D is imperative for strengthening your immune system. If you’re not able to get outside, consider a Vitamin D supplement as a substitute. Fresh air is good for everyone and a change of scenery is always a plus. Of course, with exposure to the sun, it’s also equally as important to wear SPF — and wear it daily.

      Be Mindful

      Keep stress minimal; meditate or pray, and allow your brain some down time. Nothing good ever comes from worrying. Your body will be in a more relaxed state and feel rejuvenated with some peace and quiet. Stress can be an inhibitor of immunity for the way it creeps in and likes to settle, affecting appetite, sleep habits, even daily routines.

      Promote Gut Health
      Your gut knows when you’re happy … in fact, your gut know nearly everything. Keep it in check!

      Foods with good bacteria, like yogurt, have positive health benefits. Probiotics can help your digestive system function normal and stay balanced. After all, 80% of your immune system is located in your digestive system, so it’s best to keep your stomach healthy and happy.

      Get Enough Sleep

      It’s a simple thing, really, getting a good night’s sleep. It’s your body’s chance to rest and recover. Aim for 7-9 good hours each night. Removing distractions, going to bed when you’re tired, and eliminating sugary foods late in the day will help you when you hit the pillow.

      According to the Mayo Clinic, “During sleep, your immune system releases proteins called cytokines, some of which help promote sleep. Certain cytokines need to increase when you have an infection or inflammation, or when you’re under stress. Sleep deprivation may decrease production of these protective cytokines. In addition, infection-fighting antibodies and cells are reduced during periods when you don’t get enough sleep.”

      Little Daily Habits = Long Lasting Effects
      Replacing bad health habits with good ones can help you keep a strong immune system. Here are a few little daily habits you can easily incorporate:

      Wash your hands frequently — and not just during pandemics!
      Eat more fruits and vegetables
      Laugh more
      Reflect on gratitude
      Use sunscreen
      Drink plenty of water
      Monitor your blood pressure
      Take a multi-vitamin
      Have dessert!

      Use these tips to boost your immunity and be well. These habits will also help you to live a happy, healthy life.

    • Microsoft’s Windows 10X takes a lot of design cues from Google’s Chrome OS

      zareen

      Windows 10X was originally meant for foldable and dual-screen devices, but last year Microsoft announced it was reworking the software for single screen PCs. The result looks to be an experience that will provide users with access to Microsoft services in a more affordable package.

      We’re expecting the first Windows 10X devices to launch later this year, but an exact timeframe hasn’t been revealed. Similarly, we’re not sure how much these devices will cost, but if we had to venture a guess they’ll be in the $400 to $700 range.

      In Windows Central’s video, we get a good idea of what using Windows 10 will be like, from the reworked taskbar to running progressive web apps (PWA). The video demonstrates some of the software’s settings, the process of installing a PWA, and running apps side-by-side. It’s an interesting glimpse at what Microsoft has planned for those who want a more lightweight, tablet-esque experience.

      Windows 10X isn’t something you’ll be able to upgrade to. Rather, the software will come pre-installed on new machines similar to laptops that run Chrome OS. If you’ve been tempted by a Chromebook but are embedded in Microsoft’s ecosystem, the arrival of Windows 10X will be exactly what you’re looking for.

    • YouTube Top Creator Tips for 2021 ft.

      zareen

      Creators, happy new year!
      However you felt about 2020, the fact is it’s in the history books. To help you venture into 2021 I asked a few really successful creators for one piece of advice for your channel in the new year.
      Here’s what they had to say.
      My advice is to pre-film your content. You never know when something unexpected is going to pop up in life.
      When things get busy, you’ll be so happy you have a bunch of videos in the bank. One thing that’s really helped Annoying Orange’s longevity is the fact that we stick to a schedule.
      Fans know exactly when they can come to the channel and see new videos and that’s really valuable because it creates a trust with the audience. When you build that expectation and deliver it creates trust, and that trust will keep the audience coming back.
      But it’s important to be consistent in more than just your regular uploads. Try to be consistent with your editing, your content, your style and your overall brand.
      My advice is get others involved. While no one will ever be as passionate or dedicated to your channel as you are
      by getting others involved, whether as employees or even just friends it can help improve your content allow you to focus on the things you’re best at and give you somebody else to hold you accountable when trying to achieve your goals.
      From what I learned in 2020 myself it would probably be don’t put yourself in a box. I was just trying way too hard
      to make sure I was doing exactly what my followers wanted to see exactly what my subscribers wanted to see.
      I was afraid that if I did anything different that they wouldn’t like it.
      But at the end of the day, I didn’t know that until I tried it.
      That risk pays off a lot of times. I watched so many of you put out ridiculous content every single day. However, you take the comments for granted. Get in there, reply, engage, build relationships. This is not just consumption, this is community. You are an influencer. You influence!
      So, when you’re creating your content, think not only about yourself but about others and how you want to influence their life.
      Make sure you’re inspiring them in a way that you would like to see the world evolve into whether you’re making them happy after a long day of work or maybe you’re turning into creatures and monsters to inspire them to be creative.
      That’s what I do! You are an influencer and you will influence the people that watch you.
      Be that good inspiration.
      My advice is to find balance.
      Don’t just work all year.

      Make sure you schedule time in to play and find hobbies. because if you show up to work and you’re burned out your audience will sense it and you’ll struggle to create new, authentic, and exciting content that your audience will love and want to keep coming back for.
      So, take good care of yourself so that you can take great care of your content and it will continue to motivate and inspire your audience.
      My advice is to think big and try not to be discouraged by short-term hurdles. In the long run, the only things that matter are making good content and staying consistent.
      Good luck to you.
      I’ll see you in the frickin’ interwebs.
      I’ll see you out there!
      All right, I’m done.

    • Are the vaccines halal or not?

      kiran Naqeebi

      Are the vaccines halal or not?
      Gelatin derived from pigs is used as a stabiliser in some vaccines but the consumption of pork is forbidden to Muslims, who make up some 90% of the Indonesian population.And messages have been circulating on social media in Indonesia saying that the Sinovac vaccine contains elements of monkeys.

      President Widodo, a Muslim himself, has said it shouldn’t matter because it’s a heath emergency, but some have been looking for religious guidance.

      The Indonesia Ulema Council or (MUI), whose job it is to decide such things, held long discussions and after an in-depth audit, it announced that the Sinovac vaccine is halal.

      Previously, 30-40% of people surveyed by the Ministry of health had expressed doubts about the Covid-19 vaccine, and 7% said they did not want to be vaccinated.

      Concern about whether the vaccine was halal or not was one of the key reasons, said Dr Nadia.

      “Praise be to God, that has been cleared up,” she said.

      The Waterfall model is the earliest SDLC approach that was used for software development. The waterfall Model illustrates the software development process in a linear sequential flow. This means that any phase in the development process begins only if the previous phase is complete.

      The spiral model is a risk-driven software development process model. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as incremental, waterfall, or evolutionary prototyping.

      Triggered MAN

      Topic :
      Major Highlights of Agriculture Sector of Pakistan in (2019 to 2020)
      Introduction:
      Agriculture constitutes is the largest sector of our economy.

      Majority of the population, directly or indirectly, dependent on this sector.

      It contributes about 24 percent of Gross Domestic Product (GDP) and accounts for half of employed labour force and is the largest source of foreign exchange earnings.

      It feeds whole rural and urban population. Realizing its importance, planners and policy makers are always keen to have reliable area and production statistics of agricultural crops well in time.

      Policy makers primarily need accurate and timely statistics for the important crops such as wheat, cotton, rice, sugarcane, maize etc.

      Agriculture contributes 18.5 percent to country’s Gross Domestic Product (GDP) and provides 38.5 percent employment to national labour force.

      But it remains backward sector of the economy while high performing agriculture is a key to economic growth and poverty alleviation.

      Over the last decade, the performance of agriculture sector has fallen short of desirable level, mainly because of stagnant productivity of all important crops.

      Cropped area of the five traditional crops has also largely remained unchanged.

      Climate change also poses a serious challenge to Pakistan’s agriculture and threatens country’s water availability and food security.
      The government of Imran Khan is trying its best to help the farmers by providing agriculture inputs at affordable prices and ensuring better prices of their produce.

      To guarantee food security, it is necessary to enhance domestic agricultural production through increased productivity (increasing per acre yield).

      Although Pakistan has rich production potential in agriculture, livestock and fisheries, yet for sustainable economic growth and prosperity, the development of these sectors on long-term basis is of fundamental importance for country’s growth and prosperity.

      This calls for efficient utilization of production resources by adopting modern technologies and establishment of realistic marketing system.

      The Prime Minister’s taskforce on agriculture has taken a holistic view of the issues faced by the agriculture sector and has made some sound recommendations for improving productivity of agriculture sector.

    • Motivation

      Triggered MAN

      What is motivation?
      Motivation is the process that initiates, guides, and maintains goal-oriented behaviors.

      Motivation involves the biological, emotional, social, and cognitive forces that activate behavior.

      In everyday usage, the term “motivation” is frequently used to describe why a person does something.
      It is the driving force behind human actions.

      Motivation doesn’t just refer to the factors that activate behaviors;

      it also involves the factors that direct and maintain these goal-directed actions (though such motives are rarely directly observable).

      As a result, we often have to infer the reasons why people do the things that they do based on observable behaviors.1

      Types of motivation:
      Different types of motivation are frequently described as being either extrinsic or intrinsic:
      Extrinsic motivations are those that arise from outside of the individual and often involve rewards such as trophies, money, social recognition, or praise.
      Intrinsic motivations are those that arise from within the individual, such as doing a complicated crossword puzzle purely for the personal gratification of solving a problem.

      Relational data model
      As a database designer, I’ll choose relational data model for the database designing because the relational model represents the database as a collection of relations. A relation is nothing but a table of values. Every row in the table represents a collection of related data values. These rows in the table denote a real-world entity or relationship.
      The table name and column names are helpful to interpret the meaning of values in each row. The data are represented as a set of relations. In the relational model, data are stored as tables. However, the physical storage of the data is independent of the way the data are logically organized.
      Relational Integrity constraints are referred to conditions which must be present for a valid relation. These integrity constraints are derived from the rules in the mini-world that the database represents.
      Four basic update operations performed on relational database model are
      Insert, update, delete and select. The Relational database model represents the database as a collection of relations (tables)Attribute, Tables, Tuple, Relation Schema, Degree, Cardinality, Column, Relation instance, are some important components of Relational Model Relational Integrity constraints are referred to conditions which must be present for a valid relation. The relational database is only concerned with data and not with a structure which can improve the performance of the model

      File transfer systems normally use hybrid cryptosystems, i.e. a combination of symmetric and asymmetric key encryption, to provide secure file transfers. Symmetric keys facilitate faster file encryptions, while asymmetric keys simplify the key distribution process.

      Relational data model
      As a database designer, I’ll choose relational data model for the database designing because the relational model represents the database as a collection of relations. A relation is nothing but a table of values. Every row in the table represents a collection of related data values. These rows in the table denote a real-world entity or relationship.
      The table name and column names are helpful to interpret the meaning of values in each row. The data are represented as a set of relations. In the relational model, data are stored as tables. However, the physical storage of the data is independent of the way the data are logically organized.
      Relational Integrity constraints are referred to conditions which must be present for a valid relation. These integrity constraints are derived from the rules in the mini-world that the database represents.
      Four basic update operations performed on relational database model are
      Insert, update, delete and select. The Relational database model represents the database as a collection of relations (tables)Attribute, Tables, Tuple, Relation Schema, Degree, Cardinality, Column, Relation instance, are some important components of Relational Model Relational Integrity constraints are referred to conditions which must be present for a valid relation. The relational database is only concerned with data and not with a structure which can improve the performance of the model
