Raft and Paxos, for example, only works if the number of failed nodes is less than half the total number of nodes in the system. However if you ever need to work with those directly, an important thing to pay attention to is that they are not perfect. Afterall, they are quite complicated and sometimes difficult to understand. I won't get into details on how these algorithms work. Zookeeper itself uses a consensus protocol called Zab (which stands for Zookeeper atomic broadcast). There are several algorithms that can be used to get consensus, like Paxos or Raft. And in this model, consensus is possible. This is known as the FLP Impossibility.įortunately, in most of the systems in practice, we can workaround this issue by modelling them as "partially synchronous systems", that is, we can apply a boundary on how long it takes to send messages between servers. In fact, it has been mathematically proven that, in an asynchronous system (meaning a system where we don't know how long it takes for messages to travel between servers), there is NO way to guarantee distributed consensus. This is know as the distributed consensus problem, which actually is one of the hardest problems in Distributed systems. So let's try to simplify & generalize the problem: given a set of servers, how do we ensure that all servers agree on a value, even if the servers might fail randomly (the value in this case would be the range assignment). The only way to do that is to make all servers agree on which ranges have been given, and which have not. In this case, when one servers in the Zookeeper cluster fails, somehow the system needs to make sure that the others don't return a duplicate range. That is why when we design systems, we design for failure. Unfortunately, in practice machines do fail, and in fact, they fail all the time. I probably wouldn't need multiple servers either, one beefy machine might be enough to do the job. If I had the guarantee that my servers never fails, then I wouldn't need Zookeeper. it is resilient to failures).Īnd that's the gist of the problem. But how does Zookeeper do that?įirst of all, why is it so hard to generate a unique sequence? Afterall, I can use a single computer to keep increasing a counter, and that would be unique, right? In fact, that solution is mentioned by Tushar in the video, but later rejected, because the counter-generating server might fail (either the machine itself crashes, or the network might go down etc.), and Zookeeper, somehow, magically provides "high availability" (i.e. Instead of answering the question "how to generate a unique sequence?" (or sequence range, in this case), this solution simply says "I'll just ask Zookeeper to give me one". The reason I think this answer is unsatisfying is because, while it works, it simply shifts the responsibility of generating the "unique" part of the sequence, which, is the hardest part of the problem, to Zookeeper. If the each server has a unique range, then they are guaranteed to generate unique sequences. Each server would be in assigned only one particular range to work with, and Apache Zookeeper is used to coordinate the sequence range assignments. To summarize, the most sophisticated solution proposed in the video is to partition all possible short sequences into ranges, and use a set of servers to return a monotonically increasing sequence, which falls within a range. That being said, they are sort of unsatisfying. Tushar's proposed solutions are quite good and I think most interviewers would be satisfied with them (please watch the video before continuing to read this post). The main problem is the createShort() API: How do you generate a short sequence of characters that is unique among URLs (note that uniqueness is an important property, we don't want different URLs to have the same shortcut). The second one is easy, you simply need to do a lookup and return the long URL (or 404 if none exists). This video discusses a common developer interview question, namely, how do you design a service like TinyURL, which allows users to turn long URLs into short ones that are just several characters long ( ).īasically, a TinyURL-like service would have 2 main APIs: createShort(longUrl) and getLong(shortUrl). Recently I came across a Youtube video called: System Design : Design a service like TinyUrl, from the channel Tushar Roy - Coding Made Simple. How would you design a service like TinyURL or Bitly ?

A year later, a spatial modelling study of plains zebras – the most numerous species that range from eastern to southern African – led by Brenda Larison of University of California, Los Angeles, found stronger striping patterns in areas that are warmer or receive more intense sunlight. This seemingly straightforward logic has, however, received mixed support.Ĭaro and his team found only a weak spatial overlap between striping patterns and maximum temperatures. The basic idea is that black stripes would absorb heat in the morning and warm up zebras, whereas white stripes reflect light more and could thus help cool zebras as they graze for hours in the blazing sun. Thermoregulation has long been suggested by scientists as the function of zebra stripes. “Every zebra must avoid getting hot, and biting flies will come at certain places, and certain times of the year, but they are by no means as definite or frequent a threat as overheating,” says Cobb. While Alison agrees with Caro’s findings, she thinks biting flies “seems too unimportant an effect” to have driven the evolution of zebra stripes. They believe that zebra stripes aid primarily in thermoregulation. However, other zebra researchers, like retired animal lab technician Alison Cobb and zoologist Stephen Cobb of Oxford in the UK, aren’t convinced by the parasite-deterring explanation. And in Princeton University, evolutionary biologist Daniel Rubenstein and his collaborators are tackling the question using “fly vision in virtual reality”. “It looks as if they cannot recognise that black and white surface as a good landing spot,” says Caro.Ĭaro says his team is working with “lots of unpublished data” from videos of flies approaching different patterns to learn how the stripes mess up a fly’s landing. The flies would try to land on the stripes, but then fail to decelerate as they normally would approaching a non-striped surface, and bounce off. The horseflies hovered around zebras and horses in similar amounts, but far fewer flies landed on zebras – or horses with striped coats. They observed horseflies around zebras and horses some horses had black, white or striped coats placed on them. The research at Hill Livery earlier this year, shed new light for Caro’s team. “We also found absolutely no support for the other hypotheses.” “ really showed something really remarkable to us,” says Caro. While scientists still debate the exact origins and functions of zebra stripes, their recent efforts have focused more closely on three possibilities protection from biting flies, thermoregulation and protection from predators. These striping differences, coupled with the challenges that zebras face in their environment, have guided our understanding of how the stripes might work. Striping patterns and intensity vary across species as well as location. The three living species of zebras that roam eastern and southern Africa with their coat of dark hair broken by stripes of white, unpigmented hair, are the only striped equids. Zebras, together with horses and asses, are members of the Equus genus. But, for a long time new theories were introduced without rigorous tests. Scientists have put forward at least 18 reasons why, from camouflage or warning colours, to more creative explanations like unique markers that help to identify individuals like a human fingerprint. How and why zebras evolved to sport black and white stripes are questions that have tested scientists for over a century. “People have been talking about zebra stripes for over a hundred years, but it's just a matter of really doing experiments and thinking clearly about the issue to understand it better,” he says. For Tim Caro, an ecologist from the University of St Andrews who has been studying zebra stripes for almost two decades, the livery yard’s relatively tame zebras provided a rare opportunity to stand within metres of them and observe them.

Teaching Experience: Many PhD programs offer opportunities to gain teaching experience by assisting in undergraduate courses or delivering lectures.Here are some of the opportunities you can explore during your PhD: Research is the core focus of a PhD and numerous additional opportunities can enhance your experience and broaden your skill set. Getting to know the PhD full form, educational requirements and concepts, is it the end of learning? NO. Beyond Research: Additional Opportunities during a PhD It is not just about spending countless hours in the library or laboratory it also involves collaboration and networking for professional development and personal development. Throughout the PhD process, it is vital to remember that your journey is unique and may differ from others in your field. During this process, you will present and discuss your research with a committee of experienced academics who will ask questions to test your knowledge and understanding. Oral Defence: The final stage of a PhD involves defending your thesis through an oral examination or defence.This is an extensive document that presents your research findings, methodology, and analysis in a structured and coherent manner. Thesis Writing: As you progress with your research, you will start writing your thesis or dissertation.This typically involves designing experiments, collecting data, and analysing results to draw meaningful conclusions. Original Research: Once you have a solid foundation from your literature review, you will begin conducting your original research.This helps you gain a deep understanding of the current state of knowledge and identifies any gaps or areas for further exploration. Literature Review: The first stage of a PhD involves conducting an extensive review of existing literature in your field.Let us take a closer look at the different stages involved in the PhD process and learn in detail about what is the meaning of PhD: It involves several stages and requires perseverance, resilience, and a strong passion for your subject of study. Learning about the PhD full form and basics is easy but embarking on a PhD journey is no easy task. The Journey towards a PhD: The PhD Process For example, in some countries, you may be able to enter a PhD program directly after completing your undergraduate degree. This depends on the field of study and the country in which you are pursuing your degree. In some cases, it is possible to pursue a PhD without a Master's degree. However, this can vary depending on factors such as program structure, funding availability, and any additional training requirements. The typical duration of a full-time PhD program is around 3 to 4 years. Now that you know about the PhD full form and other related aspects, you might be wondering how long it takes to complete one. Duration and Requirements: How Long is a PhD? In addition to a PhD, there are other types of doctorates available in various fields such as Doctor of Education (EdD), Doctor of Business Administration (DBA), Doctor of Engineering (EngD), and many more. While a PhD full form stands for a type of doctorate, not all doctorates are PhDs.Ī doctorate is any qualification that awards a doctoral degree. You may have also heard the term 'doctorate' being used interchangeably with 'PhD', but they are not exactly the same thing. Understanding the Difference: What is a PhD Degree vs Doctorate Let us now get into deep insights on the PhD full form and its educational background. In simple terms, a PhD is about pushing the boundaries of what is currently known and discovering new insights that can benefit society as a whole. It is the highest level of academic qualification one can achieve in their field of study.Ī PhD involves original research, critical thinking, and making significant contributions to the existing body of knowledge in your field. But what is the PhD's full form in education and its significance? Well, 'PhD' stands for Doctor of Philosophy. So you have probably heard the term 'PhD' being thrown around quite a bit, especially if you are in the field of research.

On top of this fixed-rate fee, PayPal also charges a percentage of each transaction’s total. Some of the most popular currencies and their respective fees include: This fee will vary depending on the transaction’s currency. To start, PayPal applies a fixed-rate fee to each applicable transaction. So how much should you expect to pay each time you receive money through PayPal? And in most cases, these fees are charged to the person or company receiving the money. To do this, PayPal charges a fee for most transactions that go through its system.

Instead of giving your bank account information directly to a company or individual, PayPal acts as a secure third-party.

It’s true that paying out a percentage of your income to get your money in the first place is a pain. However, many freelancers and entrepreneurs are less than thrilled about paying numerous PayPal fees for receiving money from clients. Of these services, none is more popular than PayPal.
