In the realm of programming, where lines of сode сonvey сomplex instruсtions and ideas, the use of emotiсons and emojis may seem out of plaсe. However, in reсent years, developers have inсreasingly embraсed these visual symbols as a means of enhanсing сommuniсation, expressing tone, and fostering сamaraderie within development teams. In this artiсle, we will explore the power of emojis in сode, examining their role in сonveying emotions, сlarifying intent, and building a sense of сommunity among programmers.
The Evolution of Сommuniсation in Programming: Traditionally, сommuniсation in programming primarily relied on text-based languages and сonventions. While effiсient and preсise, this mode of сommuniсation often laсked nuanсe and emotion, leading to misunderstandings and misinterpretations among developers. With the rise of сollaborative development platforms, suсh as GitHub and Slaсk, developers began to inсorporate emojis and emotiсons into their сode сomments, сommit messages, and doсumentation as a means of adding сontext, сonveying tone, and injeсting personality into their сommuniсations.
Emojis as Visual Сues: Emojis serve as visual сues that сomplement and enhanсe the textual сontent of сode, providing additional сontext and сlarity to developers. For example, a smiling faсe emoji 😊 appended to a сode сomment сan indiсate a friendly tone or express satisfaсtion with a suссessful implementation. Similarly, a thumbs-up emoji 👍 in a сommit message сan signal approval or agreement with a сode сhange, while a сautionary emoji ⚠ may alert fellow developers to potential issues or risks.
Expressing Emotions and Intentions: In addition to adding сontext and сlarity, emojis enable developers to express emotions and intentions that may be diffiсult to сonvey through text alone. For instanсe, a faсepalm emoji 🤦‍♂️ may signify frustration or embarrassment over a сoding mistake, while a сelebration emoji 🎉 сan denote exсitement or pride in aсhieving a milestone or сompleting a projeсt. By inсorporating emojis into their сommuniсations, developers сan humanize their interaсtions, foster empathy, and build stronger сonneсtions with their peers.
Fostering Сamaraderie and Сollaboration: Emojis also play a сruсial role in fostering сamaraderie and сollaboration within development teams. Shared emojis, suсh as high-five 🙌 or party popper 🎉, сan serve as virtual сelebrations of aсhievements and milestones, strengthening team morale and fostering a sense of unity. Additionally, the use of playful emojis, suсh as the winking faсe 😉 or the laughing faсe 😂, сan injeсt humor and levity into disсussions, easing tensions and сreating a more enjoyable and inсlusive working environment.
Navigating Сultural and Linguistiс Differenсes: While emojis сan be powerful tools for сommuniсation, it’s essential to reсognize and respeсt сultural and linguistiс differenсes when using them in a professional сontext. Emojis may сarry different meanings and сonnotations aсross сultures, and their interpretation сan vary depending on individual preferenсes and experienсes. Therefore, developers should exerсise сaution and sensitivity when inсorporating emojis into their сommuniсations, ensuring that they are used appropriately and in line with the сultural norms of their team members.
Best Praсtiсes for Using Emojis in Сode: When using emojis in сode, developers should adhere to сertain best praсtiсes to ensure effeсtive сommuniсation and сollaboration. Firstly, emojis should be used judiсiously and sparingly, supplementing rather than replaсing traditional text-based сommuniсation. Seсondly, developers should strive for сlarity and сonsistenсy in their use of emojis, ensuring that their meanings are understood by all team members. Finally, developers should remain mindful of the professional сontext in whiсh they are сommuniсating, avoiding overly informal or inappropriate use of emojis in formal doсumentation or сlient-faсing сommuniсations.

Сonсlusion

In сonсlusion, the use of emojis in сode represents a powerful and evolving form of сommuniсation in the programming сommunity. By adding сontext, expressing emotions, and fostering сamaraderie, emojis enhanсe the effeсtiveness and riсhness of сommuniсation among developers. However, it’s essential for developers to exerсise disсretion and sensitivity in their use of emojis, reсognizing сultural differenсes and maintaining professionalism in their сommuniсations. Ultimately, when used thoughtfully and appropriately, emojis сan serve as valuable tools for building сonneсtions, fostering сollaboration, and enhanсing the overall development experienсe.

Everyone can get into a situation when a loan is absolutely necessary. Loans allow receiving additional money to cover certain purchases or urgent expenses, such as medical treatment or even day-to-day spendings in the event of losing a job. However, many loan types are only accessible to people with a good credit history. In case of having a poor credit score, it might be difficult for borrowers to find convenient and reliable solutions. Luckily, there are a few different kinds of loans that either do not require a credit check or accept borrowers with a poor credit history. This allows everyone to find convenient loan services that will help with receiving the necessary money. Read along to learn more about the best installment loans for bad credit and their advantages.

What Are Loans for a Bad Credit Score?

The loans for bad credit are those accepting borrowers with bad credit histories or those who have yet to build their credit scores. Installment loans are all loan types that need to be repaid in multiple installments as opposed to repaying the whole amount in bulk.

As lenders risk their money with bad credit borrowers, such loans usually come with high interest rates. Nevertheless, this allows everyone to apply for and receive a loan when necessary.

Loan Types for Borrowers with Bad Credit Scores

There are numerous loan types available these days, and they can cover a wide range of needs. From student loans to car loans, people can apply for money and receive different amounts for various purposes. There are also specific types of loans that can be accessible for people with bad credit history. Here are some of these loans:

  • Loans with no credit check. The easiest loans to get are those that do not require any credit check. This means that even borrowers with a damaged credit history have a good chance of receiving such loans. No credit check loans often come with increased interest rates though. They can be both secured and unsecured.
  • Cash advance. It is possible to borrow money from your credit card. Cash advances can be received instantly as long as there is a balance available on your card. Such loans are limited to the amount set by your bank.
  • Payday loans. Unlike many other loans, this type offers a smaller amount of money for shorter periods. Such loans are usually taken to make it to the next payday. They also should be repaid within a month normally. These loans have steep interest rates, although smaller amounts allow paying them off quickly.

Each loan type comes with its unique terms and conditions, and even if you have a poor credit score, it is essential to evaluate each lender carefully.

The Benefits of Loans for Bad Credit

Even though such loans are often more expensive than those available for borrowers with good credit history, they still have numerous advantages. Here are some key benefits of installment loans for people with bad credit scores:

  • Convenience: Most loans can be received online, and it is more convenient than driving somewhere to receive your money. After applying online and receiving the confirmation, the money is delivered directly to your bank account.
  • Accessibility: Of course, the main advantage is that such loans are available for everyone and not only for people with good credit history.
  • Terms: There are different loan types available, and everyone can pick either short-term or long-term solutions. Long-term loans usually come with lower interest rates and fees than quick loans.
  • Improving credit score: Taking bad credit loans and repaying them successfully in time allows improving your credit history. This way, you can start earning access to more beneficial loans with favorable conditions in the future.
  • Speed: Online installment loans can be received quickly. Especially payday loans can be obtained within a day if necessary. This is convenient for funding urgent expenses.

No one is immune to unpredictable situations when you might need some extra cash. Taking a loan is one of the easiest options in this case as you receive money quickly and can pay it back gradually in a few installments. Always check the terms and conditions of different lenders to find the solution that suits you best.

Most popular gambling sites, including real money online casinos in Australia: https://aucasinoonline.com/real-money-casinos/ are employing people across the globe.

This is because technology has made things possible- one can work from anywhere, anytime. However, the casinos should keep training their employees because the online gambling industry is evolving.

That is why we will work with real money online casinos in Australia to create educational video courses for their employees. They will ensure that all employees are abreast with the latest gambling trends. As a result, the casinos will offer quality services to their customers.

Who We Are?

We are IT experts helping companies with video courses. We craft informative course materials and transform them into videos. The employer can then send them to their employees despite their location.

This helps sharpen their skills, especially during this era when a revolution is happening in the gambling industry. For example, we can prepare a video course on how to create a mobile betting app. With the help of such a course, online casino employees can join forces and create a mobile app to offer a better gaming experience.

Steps for Making a Good Corporate Video Course for Employees

We work towards providing quality video courses to Australian online casino employees. Here are the steps that we follow.

Getting the Right Equipment

When creating training videos, we use the right equipment. This helps us to produce the best quality audio and videos. Usually, we use a camera, a lighting set or a tripod, a microphone, and a great video editor.

Choosing a Topic

The second thing that we focus on is the training course topic. What does the employer want their employees to get from the video course? For example, an online casino operator would like to teach their support team how to handle their customers. Therefore, we can name the video ‘Professional customer service in an online casino’.

Selecting a Format

Training course videos can be in different formats. Therefore, we need to understand the structure we will use before recording. For example, employers may want their employees to watch the video on their smartphone or from a YouTube channel. This will help to optimize the recording and editing processes.

Planning

Every project requires planning to accomplish it. Therefore, we prepare the script, design the storyboard, and set the background. This helps to ensure that we cover every detail in the course for the employees to reap the maximum. It also ensures that we deliver the videos on time.

Recording the Video

It is time to record the video. First, we set up the equipment. Then we start recording the visuals with the camera and the audio with the microphone. Usually, we work with Aussie online casino experts to ensure that we provide the correct information. In case of mistakes during recording, we ensure that we rectify them.

Editing the Video

After recording, we sit down and edit the videos. We have creative video editors who use video editors apps such as Animoto for great video training courses. We add texts, transitions, and music melodies to make the videos entertaining and memorable. This helps the employees to concentrate even as they train independently from different locations.

Distributing the Video

After editing and ensuring everything is in order, we help the real money online casinos send the videos to their employees. We can use email, post it on their communication channels, or any other recommended medium.

Getting Feedback

Getting feedback about our training video is key to our growth. We like to hear whether the video was helpful or not. It helps us to serve real money online casino operators better every time we work together.

Tips for Making Effective Video Training Courses

Creating a valuable video course for employees needs some tricks. Here is how we go about it.

Connecting with Our Audience

Before we start working on the videos, we first understand the casino employees. We know whether they have been trained on that topic before or if they are starting afresh. Besides, we engage them during recording by asking them questions and addressing them directly.

Focusing on the Information

We don’t add anything that can distract the viewers from the training videos. We keep the visuals clean and eye-catching so that they can pay attention.

Making It Fun

Sometimes watching training videos alone can be tedious. However, we add music, jokes, graphics, and other entertaining elements to keep them lively. This is to ensure that the employees learn in a fun environment.

Keeping Them Short

We understand that no one wants to watch a lengthy training video. Therefore, we keep them as short as possible. If a topic requires much to be covered, we divide it into small parts and create a video series. This helps to keep the learners engaged without losing them along the way.

Benefits of Video Training Courses for Employees

Why should real money online casinos use video courses to train their employees?

They Are Flexible

These courses can be used anywhere across the globe. Therefore, the casino doesn’t have to pay for flights to transfer employees from different countries for training. They only need to create the courses and send them to their employees. This helps to save on money and time.

They Enhance Knowledge Retention

The purpose of training employees of real money online casinos in Australia is to sharpen their skills. However, when one learns something, they may forget with time. With video training, the retention rate is better compared to other forms of training. Besides, one is likely to watch an exciting video repeatedly. This enhances the retention capacity.

They Engage Learners Better

Sometimes, employees can be busy with the things of this life, and when they are being taught, they may not absorb the knowledge. However, videos can help to grab their attention through the help of creative elements such as graphics. Besides, video training breaks the monotony of a lecture setup, which can be boring sometimes.

They Help in Being Consistent

Through video training courses, all employees are trained the same way and get the same information. This helps them to be on the same page while on duty. As a result, it reduces mistakes and issues between them.

They are More Comprehensive

Although videos are visuals, they also have an audio component. Therefore, the employees will see and hear as they learn, making it easy to absorb what is being taught. Besides, some of the complex ideas are better explained with the help of visuals. This makes them get the most out of the training videos.

Conclusion

Employee training is a crucial aspect of every company for quality delivery. It is even more critical in evolving industries such as online gambling. Therefore, real-money online casinos should frequently commit their resources to training their employees.

The best training method to use for online casinos is video training. This is because it accommodates all employees despite their location. Besides, it is cost-effective and promotes better knowledge retention.

If you are a real money online casino operator looking for quality video courses to train your employee, we got you.

Many business owners and marketers wonder if and when their organization would benefit from a mobile app, but it can be hard to know what circumstances warrant the time and budget to create that app. The first question you need to answer before moving on any further is “Do I have a website?”. If that answer is “Yes” then continue to consider an app, if the answer is “no” then stop thinking about an app and create a really high-quality mobile-friendly website.

But let us examine why many businesses including esports bookmakers are switching to esports betting apps.

Easy Reach to The People

With smartphones and tablets becoming the hardware of the choice, there has never been a better time to consider creating your own app. The accessibility of these devices is surprisingly high and this is very appealing to many businesses including esports bookmakers which is why they switch to esports betting apps. Unlike a website, an app is very specific and contains directional information. People don’t like to waste their time lingering on a website trying to figure out how to carry on a simple function, hence an app with an extremely user-friendly interface will support the growth of your business.

Helps in Targeting The Audience

There are a lot of surveys and forms that can be passed out these days on various online platforms. Filling out these forms takes less than a minute which is why customers or potential clients fill out these surveys with a smile on their faces. With the help of this, you can work towards building a specified and personalized app that reaches out to the interests and issues of your target audience only.  This is one of the major reasons why you should switch to an app.

Help in Generating Additional Revenue Streams

Coming up with an idea is actually the easier part of the plan, getting it downloaded enough to turn a profit is a tricky part. Bear in mind that the reason apps are downloaded in their millions is because they are incredibly useful to people and serve an important purpose. Being creative with your revenue model can make all the difference between profit and loss. There are various new and potential possibilities for you to diversify the general purpose of your app and turn it into something much more useful and applaudable thus helping in creating additional revenue streams.

Useful Pictography

We understand from the above points that an app serves a meaningful purpose in the life of most businesses, but how does it help the esport bookmaker business? The sports betting business requires pictorial representation of data and more importantly, it requires customer feedback so that you can make the amends according to the needs of your users. And various apps have been successfully developed that cater to these very needs of the people you can check this application. All of these facilities have been squeezed down into one esports betting app and the results are wonderful.

Conclusion

It can be fairly concluded that a mobile application is a much better place for a business to grow and interact with its user base when compared to a website. There is a wide range of things that one can do with his app and turn it into a garden of profit.

The digital world has taken over nearly every industry and a smartphone is a perfect example of that. Just think of all the tools it has replaced; GPS devices that used to be bulky contraptions stuck to car windshields with suction cups, glove compartments full of paper maps that were frustrating to fold, answering machines were clunky devices that used actual cassette tapes and sat on tables next to the phones mounted on walls, and if you wanted to click a picture or record a video you needed a camcorder and a camera.

Every one of those tools is now an app, which means someone saw a need for a piece of software designed for that specific purpose. We use apps for almost everything because they are convenient, helpful, and extremely user-friendly. But have you ever thought about the process of making them so easy to use? When you imagine all of the ways a user might interact with an app from creating their own profile to communicating with the other users, there is a lot to consider but it all starts with the app’s visual design. We will talk all about that here in this article and if you stick through it, you will learn about the most effective ways in which you can create a user-friendly app

Effective User Interface

The visual parts of an app that a user interacts with are called the app’s user interface. Consider all the types of interactions that a user interface might need to accommodate. The first and foremost being a profile photo and personal details or maybe they’ll use their phone’s camera to scan items through the app, or the app could be a simple game that they can play while waiting for the bus in which case they’d wanna share high scores on their favorite social network. Or it could be as complex as keeping a detailed monthly budget with up-to-date banking information. For every one of these scenarios, developers need to create a ‘Test Case’ to make sure that a specific function flows smoothly for the user.

Develop A Prototype

An important task in implementing a user-friendly app is to first create a prototype and make sure there are no loopholes. To ensure this you will have to proceed step-by-step, first starting by creating a paper prototype and quickly testing your ideas. Developers can share these paper prototypes with potential, users of the app without having to write any code.

Highlight The Importance

It is important to ensure that the app you are designing has an actual real motive and intends to address an issue faced by the target audience. You must highlight the importance of your application so that people get to know about it and are genuinely interested in using your app. So, make a useful app and then highlight its importance.

Safety is Foremost

 The last thing you want is your app to be compromised by swindlers. This will question your authenticity and users might hesitate before using it. The whole point is to create a safe environment that will promote user-friendliness and in order to do so, you must ensure safety and security on your platform.

Conclusion

It can be easily concluded that in order to promote the use of your user-friendly app you must address the needs of your primary target audience and make them believe that it is something useful and not a hoax controlled by swindlers and scammers.

Programmers, go to interviews. https://www.dnrtv.com/programmers-go-to-interviews/ Mon, 11 Apr 2022 16:38:55 +0000 https://www.dnrtv.com/?p=127 A programmer is a person who writes and tests code for software.

A programmer is a person who writes and tests code for software. The term “programmer” can apply to a variety of positions, including developers, programmers, engineers, etc.

Programmers usually spend their time writing programs and applications in different computer languages like C++ and Java. They also design new operating systems, such as iOS or Android, сode developers are working on all different types of projects at the same time. You need to be able to create & test code, as well as fix errors and broken lines or code, do general maintenance work and oversee development for websites or programs. And all of this needs to be done in an integrated development environment (IDE) too.

When looking for a job, you can do so by what languages ​​programmers work with (C++ programmer, Java programmer, PHP programmer), the task type (1C programmer, web program, front-end and back-end developer) or their level (intern, junior or senior).

However, programmers often work from home and can struggle to find new job opportunities. Interviews could help them in their job search because there are many different facets of this line of work. One of the challenges of remote assistance work is an inability to gauge your level of expertise. You might not know what you’re good at, or be terrible at something, but there’s no way to tell without experimenting. You’ll need to try many different projects and take on a lot.

A system programmer is a jack-of-all-trades: you code, debug hardware, and solder things. Occasionally, the adjustments for the iron are then transferred to developers. To work in the field of digital circuitry and programming, you need a fairly broad knowledge. You’d usually have to go through interviews where they test your knowledge in both areas.

Going to interviews is a good idea if you love your job. You will understand your level and be able to compare if it’s worth looking for other opportunities. You might not think this, but people often see the most valuable interviews as those that failed. These ones give an accurate representation of where you need to work on improving.

Another interesting feature is interviews. A vast majority of interviews are pretty straightforward, but if it seems like you’re going through 12 circles of hell- an interview with HR, and one with programmers, the CEO and more assignments before you accept a job offer- then there’s a good chance that these people were just not for you. As a general rule, extensive bureaucracy and long hiring procedures usually occur for companies that have similar processes.

One of the best things you can do when you’re interviewing a candidate is to ask them to show code that they’ve done. This makes it easier for you to get an idea of their level of experience out in the field. When it comes time to select people, this is one of the most effective methods. In reality, you can’t push yourself to do your best when interviewing. You’ll either get too excited or too nervous. But it’s different in the workplace, where you need to work continuously on priority tasks.

Programming tasks are especially valuable during interviews and often test your skill under pressure. The first test is to solve a problem quickly and accurately in stressful situations- so if you can do it during an interview, you’ll be capable of doing the same while under time pressure later on. The second one highlights your abilities and shows that you can solve current problems.

I’m always grateful to the people who have taken their time to speak with me, and for giving me the chance to realise what it’s like trying to work in a new environment. The topic I found the most interesting is what, specifically, an interviewer will be looking for when they invite candidates over. People often ask about bit operations when it comes to programming for a system or microcontroller. So if you’re looking for that position, prepare yourself accordingly in this field.

Another example of polarity is pointers, which should help you to remember everything. This will make them *bounce* off your teeth, so that it wakes you up in the night and you can show and tell everything.

How do failed interviews help us? For me they’re the most important part of learning to program. It shows how easily I can mess up, which might not be clear if all my tests passed. For example, a specialist before this interview was very familiar with each of the questions and they were constantly practicing in advance, but for some reason they weren’t given much thought and you don’t understand them at 5. That’s why this exam is. And this will act as soberingly as possible. You think that you are a cool specialist, you know circuits, interfaces, work with the kernel. And then you have real questions and you swim.

It sounds like a successful interview is no guarantee of a successful job for you. One of the main problems is that the candidate successfully solves problems at interviews, shows themselves to be an excellent specialist, but then struggles on their very first real task. Get one step ahead and make sure these don’t happen to you by having someone else work out your tasks for you in advance. One of the most difficult things about a company is figuring out how to stay with them. The best way to make sure that you’re going to be able to stay, is by starting the interview off simple and understanding: after 1 month at our company, it’ll be clear whether we want you or not. This approach is what suits you best of the ones mentioned, yes, it’s a bit more expensive, but it is clear who you are talking about right at first.

There is another option for interviews. When the interviewer manages to pass their own test, they might still realise that they don’t have what it takes to work as an individual employee. This means that I politely decline working for them if I am offered a position as an individual employee. It’s important for a programmer to consider the other factors on their team and how they contribute to the company’s needs. Employers have a lot of responsibility in trapping their clients and programmers are responsible for doing their part in that process.

And one important piece of advice. If you see tyranny at the questioning stage, then respect yourself, get up and walk away – this is normal. If the HR person and manager at the interview overstep their boundaries and make you feel uncomfortable, this probably means that company culture is toxic and it’s not a job you should work for unless you like being managed unfairly.

IT is a great field of work that offers lots of promising prospects and opportunities, especially for those who are looking to make bigger bucks. However if money is your primary motivation and you’re not interested in a more stretched out and flexible working schedule, then you should rethink your decision to pursue this line of work. At the end of the day, IT workers have to constantly be. The courses may not teach you everything that a beginner programmer would need to know. If you finish the course, it is possible that you will have more questions than before.

If you’re interested in the process feel free to head over to our site, we have a wealth of resources on development interviews. The best approach is to come in confidently, even if you make some mistakes, as opposed to someone who has excellent credentials but appears nervous in an interview.

These days, it’s hard to remain anonymous online. Whether you’re surfing the Internet or just using software that goes online, know this: you’re being watched. Even your operating system isn’t sleeping.

Once you start Windows or a VS Code type program, you are tracked by telemetry. Of course, most of the data you collect is used to improve the software you use every day… and if anonymity is your goal, it’s worth looking into additional options.

Linux distributions offer various options for increased anonymity and privacy. But anonymity has its drawbacks.

Before we continue, we would like to make an important disclaimer. The purpose of this article is to tell you what you can do to protect your privacy. This article is not a call to do anything that is illegal in your country.

What does it mean to be anonymous?

“Anonymity” means different things to different people. So let’s understand the basic concepts right away.
The first thing is to understand who you want to hide your identity from, and what tools will help you do so.
You can use the threat modeling approach to properly categorize your risks. In this regard, the National Institute of Standards and Technology (NIST) suggests 4 steps:

  • Identify and describe the system and data of interest;
  • Identify and select the attack vectors included in the model;
  • describe security measures to mitigate the attack vectors;
  • Analyze the threat model.

You can read more about threat modeling in the NIST handbook.

Take journalists, for example. They would probably prefer to share their thoughts online anonymously. It would save them from fear of persecution and possible reprisals. That is, journalists do not want people to be able to reveal their identity. Thus, they clearly understand from whom they intend to hide.

Once you have decided from whom you want to hide, you can move on to the next step – the choice of profile tools (such as Tor) or Linux distributions to maintain anonymity.
Of course, anonymity has many advantages. I will only highlight the most important ones:

Freedom of speech: you can express your opinion without fear of being judged;
Less traceability: it will be more difficult to track what you are doing online;
Personal security: your data is a treasure. And it is much more difficult to steal it from an anonymous person.

Examples of Linux distributions

In principle, Linux systems are more secure and privacy-oriented than their proprietary brethren. Therefore, it is important to clearly understand exactly how Linux distributions work and how they keep you anonymous.

Virtual machines

A virtual machine is a kind of virtual computer that runs on top of your main computer.
Virtual machines are isolated from the rest of your system; you can run almost any operating system in them, including Linux distributions.
The most popular program for running virtual machines is VirtualBox, the open-source hypervisor from Oracle. VirtualBox is easy to set up and runs on Windows, Linux and macOS.
From the average user’s point of view, the main advantage of virtual machines is that you can run them in parallel with the underlying operating system, i.e. work in two systems simultaneously.

Live USB bootable USB stick

Live USB launches an operating system without installing it on your computer. With the Live USB you can install the Linux distribution and get right into a working environment. For the sake of clarity, here is the Parrot OS working environment (see below).
The main advantage of the Live USB is that you don’t have to waste time installing it. You just plug it into your computer, run the Linux distribution, unplug the USB stick and get on with your familiar operating system.
If you want an example of a full-fledged operating system on a VM, take a look at Qubes.

Installing on a computer without an operating system

If you’re aiming to be invisible, then installing a Linux distribution on your main OS is not a good option, because you will have to run many sessions on your computer.
Whenever you work on your computer, you leave a trail of data about the sites you visit, the files you open and even the Wi-Fi network you use.
That’s why working through Live USB flash drives and virtual machines is more secure.
Let’s say you’ve done everything you need to do in your work environment. You turn off that environment, and all the data is gone. It’s the same with virtual machines – when you’re done, they’re simply deleted.

Webhooks are used to integrate various services when coding. But what is a webhook? In this article we’ll explain what webhooks are and what they are used for.

A webhook is a POST request handler. It waits to be called to perform a certain action.

I will explain more clearly on an example. I sell my courses through Paddle. When someone signs up for a course, a webhook is called with JSON data. This data includes the customer’s mail and name, as well as the name of the product.

The webhook is responsible for adding the customer to the Airtable database and sending a confirmation email with the necessary information.

In my case, the webhook is a Node.js application with the Express framework, but in general it can be any application that is accessible via the Internet and is capable of receiving network requests. I placed the webhook on a VPS, although I could have limited it to serverless function.

Basically, all payment systems offer webhooks to process the payment and perform the actions you want.

Another example of using webhooks is to run certain tasks on your computer. For example, all deployment platforms offer webhooks that are called to start a new deployment.

I use one in Netlify or Cloudflare Pages. I have an IFTTT task: every day at 8am it triggers a deployment to publish a scheduled blog post (trigger condition: publication date passed).

We have all encountered various digital viruses. The Internet is now full of them! But did you know that sometimes they can harm not only individual devices, but entire countries!

We will go on to talk about these, the most malicious of all existing computer viruses.

CryptoLocker

This dangerous software was released in 2013. It was distributed via email in the form of an ordinary letter with an attached program. When you open the message, the file automatically launched, and then encrypted all the files stored on your computer. In order to regain access to their documents, the victim had to pay a large sum of money, in bitcoin. Having done so, the user received a key that was of no use to him at all: the data infected by CryptoLocker were lost forever.

Zeus Gameover

The Zeus application became known 10 years ago. It targets Windows operating systems. The infection occurs in two main ways: via spam and downloaded files. Zeus Gameover aims to get to the user’s bank details and withdraw all the funds from his accounts. The virus is great at scanning sensitive information and can even download ransomware that encrypts files and then demands money to unlock them. For the capture of the Zeus creator, Russian hacker E. Bogachov, the FBI in ’15 offered a record-breaking reward of $3 million.

PlugX

Our third sample is a Trojan that has been infecting PCs worldwide since 2012. It has remote access capability and affects mostly government organizations by spreading via email. The malicious attachment exploits vulnerabilities in Adobe Reader and Microsoft Word. It has several spyware modules that perform various tasks. In 2016, the Japanese travel agency JTB Corp was attacked by PlugX, and it gave nearly 8 million user records into the hands of cybercriminals. The incident was caused by an email that a company employee received and opened.

Stuxnet

Stuxnet was first discovered in ’10. It originally targeted Iranian nuclear facilities. On one occasion, the virus destroyed over a thousand centrifuges at a large Foolad Technic facility. The way Stuxnet spreads is via USB sticks. It is also known that Siemens, a German firm, was once severely affected by it.

Mydoom

This worm was spread via email and peer-to-peer networks. It was written in the Russian Federation in C++. MyDoom embeds a flawed algorithm in the operating system and triggers a DDoS-like mechanism. In its first year it flooded the Internet and infected about 20% of all e-mail messages. MyDoom’s carrier file has a line with the words “I’m just doing my job, nothing personal, sorry.” By infecting the operating system, the worm blocks antivirus sites and Microsoft resources.

Sasser and Netsky

Worms created by a 17-year-old German, S. Jashan. They operate in different ways, but similar in code. Sasser is difficult to stop: when it enters a PC, it looks for other vulnerable devices by scanning IP. This worm doesn’t cause any catastrophic data damage, but it slows down the networks and performs a lot of DDoS-attacks. In Year 4, it shut down almost all Taiwanese post offices, 130 bank branches in Finland, and caused the cancellation of several train flights and transatlantic flights.

Netsky works differently. When it gets on a PC, the user is unable to open files. The virus downloads malicious elements into Windows and settles in the autorun. Notably, at the moment of infection it wipes Mydoom from the system, if it is present there, of course.

CodeRed

This malware, after infiltrating a computer, makes several hundred copies of all the data stored on it. As a result, the worm consumes too many resources and causes the system to “crash”. What follows is a standard DDoS attack. The most famous Code Red case was the “attack” on the White House portal. Experts believe that in 2001, the virus infected over 250 thousand computer systems, causing more than $2 million worth of damage.

Nimda

Also in 2001, the Nimda virus appeared on the web. In just 22 minutes after its “release” it became the most popular tool for cyberattacks. The main purpose of this software is to give the hacker full access to the device. Nimda has reportedly infected approximately 160,000 operating systems worldwide.

ILOVEYOU

In May 2000, thousands of Internet users received an e-mail containing the same text: “ILOVEYOU.” A file was attached to it, which gave criminals full access to the operating system when opened. The virus is considered one of the most dangerous, since it infected 10% of all PCs on the planet and caused $10 billion worth of damage. Many governments even had to shut down their email systems for a while to prevent ILOVEYOU attacks.

Strange programming languages?

When developers get bored with standard serious languages, they start inventing new, more unusual and interesting alternatives. And this case is not only fun, but also useful.

Specifically, the benefit of such exotics is that they help programmers learn the limits of languages and sharpen their skills even more effectively. Strange languages usually have a more complicated syntax and therefore are understandable only to a small group of dedicated people.

WHITESPACE

The creations of this category usually have eloquent names. Whitespace is no exception. In 2002, two comrades decided to create a language based solely on non-printable characters. The public at the time thought this idea was just a joke, but the language not only came into being, but also gained some popularity. Meanwhile, the international vocation of Whitespace has not yet won.

CHEF

A very funny language, designed for people who like to cook and want to learn how to program. It looks like a recipe and follows these principles:

the output created by the code should not just be technically useful, but also tasty and easy to prepare;
the recipes should be different in terms of budget;
the code should act like regular code, but at the same time be edible.

SHAKESPEARE

The variable names in Shakespeare are the same as the names of the characters in his texts. Their interaction takes place in scenes where acts of input and output are performed, questions are asked, and answers are received. According to the rules, there can be no more than two Shakespearean characters working simultaneously.

BRAINFUCK

You may be surprised, but it is quite a well-known and popular programming language, although it was created only for fun. BRAINFUCK consists of just these 8 characters:

>
<

+

.
,
[
]

CHICKEN/OOK.

And here you will see only one word – chicken. Apart from chicken, the code page does not contain any other characters. A Swedish developer created this language after a parody of D. Zongker’s scientific papers.

OOK is built on the same principle, but it has 4 variations of the word:

Ook,
Ook!
Ook.
Ook?

It has been reported that this unique tool was created just so it would be available for use by orangutans. Yes, you got that right, and this is no humor.

INTERCAL

If the language algorithms were very obscure in the past examples, here they are quite standard. The only thing that separates Intercal from its more serious brethren is a little “surprise.” The irony is that it implies the use of completely useless words (which, by the way, was a sin of many codes in the early days of programming). For example, in some version it is obligatory to write “please” for each operation, otherwise it won’t do them.

ENGLISH

The easiest of our list of languages because it mimics natural English. The free syntax is very convenient and gives the developer tremendous freedom of expression.

MALBOLGE

This is the moment when it’s not funny at all. The name is taken from Dante’s brilliant work “The Divine Comedy”, in which the word “Malbolge” refers to the 8th circle of hell, where the cheaters were. As you can see from the example, creating even a simple program in this language is almost unrealistic. The funny thing is that most of the code written in Malbolge was created with other programs and trivial searches.

And the interesting thing is that this is not all the crazy and absurd languages you can use to write fun code and train your brain!
