Also, LeetCode is pretty addictive. They have gamified the system nicely. You get points for solving daily Challenges and for participating in contests. You can compare your global ranking against the others, based on number of problems you have solved and your ranking in real-time contests. (Which I have participated in few occasions, and which in itself has been very humbling experience).
Few observations about the contests. What I have seen, most of the top contestants are from Japan, China, Taiwan or USA. You have to go long in the list to see any other nationalities. Also, the best of the best are extremely fast; they must have in-built compiler/debuggers in their heads (And yes, some may use library solutions, i.e. cheat, and yes, most have been doing this for a long time). So, what is a LeetCode contest? You are given four different problems to solve in 90 minutes and are scored based on multiple criteria. Example problem set below:
Coding under time pressure is like playing musical instruments in front of a live audience. You must have strong routine which allows you to perform almost without thinking (though in coding contest you actually do need to think). Point being, even under pressure, you can rely on your strong routine and background, if you have trained well.
I do have to say that I master computer algorithms now better than I ever did, even after graduating from University of Oulu. There are excellent online resources easily available nowadays, and this really is a good thing for the industry in general.
If you do decide to take on LeetCoding challenges yourself, do read some tutorials first to refresh the basics. Do not spend too much time on any given problem if you can't solve it in less than 30 minutes, but look at the Solutions (if available); remember you are learning here so don't take it too seriously. Also, do look at the discussions and review how other people have solved the problems (and you may learn new tricks about the language of your choice in the process!). I've found this to be the most rewarding aspect of LeetCode myself.

Algorithmic trading allows traders to perform high-frequency trades. The speed of high-frequency trades used to be measured in milliseconds. Today, they may be measured in microseconds or nanoseconds (billionths of a second).
Yes, algorithmic trading is legal. There are no rules or laws that limit the use of trading algorithms. Some investors may contest that this type of trading creates an unfair trading environment that adversely impacts markets. However, there's nothing illegal about it.
Algorithmic trading relies heavily on quantitative analysis or quantitative modeling. As you'll be investing in the stock market, you'll need trading knowledge or experience with financial markets. Last, as algorithmic trading often relies on technology and computers, you'll likely rely on a coding or programming background.
Yes, it is possible to make money with algorithmic trading. Algorithmic trading can provide a more systematic and disciplined approach to trading, which can help traders to identify and execute trades more efficiently than a human trader could. Algorithmic trading can also help traders to execute trades at the best possible prices and to avoid the impact of human emotions on trading decisions.
However, it is important to note that algorithmic trading carries the same risks and uncertainties as any other form of trading, and traders may still experience losses even with an algorithmic trading system. Additionally, the development and implementation of an algorithmic trading system is often quite costly, keeping it out of reach from most ordinary traders -- and traders may need to pay ongoing fees for software and data feeds. As with any form of investing, it is important to carefully research and understand the potential risks and rewards before making any decisions.
Because it is highly efficient in processing high volumes of data, C++ is a popular programming choice among algorithmic traders. However, C or C++ are both more complex and difficult languages, so finance professionals looking entry into programming may be better suited transitioning to a more manageable language such as Python.
Professor Christopher Gold has worked on the development of GIS methods since the 1970s, and is particularly concerned about the integration of geographical analysis and algorithms, and cooperation with the Computer Science community. As well as his current emphasis on spatial data structures and algorithms, he has had extensive experience in applications such as forestry, geology, landscape modelling and marine navigation. Professor Gold has been active for over 30 years in the development of spatial data structures, spatial models of perception and adjacency, Geo-informatics applications, and algorithms.
Chris Gold has devoted much of his research career to techniques of spatial analysis. In this new book many of his most important contributions are assembled in one place for the first time, along with related material, and covering applications that range across the environmental and social sciences. The book will be of great interest to researchers from across those disciplines, as well as to specialists in computer graphics, computational geometry, photogrammetry, cartography, and remote sensing.
Unlike many competing books, the author of this one has chosen to present algorithms descriptively, rather than in code or pseudocode. This makes the book eminently readable, but perhaps of most interest to those who are able to turn the descriptions into code, or to value them as insights into what goes on under the hood of geographic information technologies. The text is very well illustrated with black-and-white diagrams, and mathematical notation is clear and easy to follow.
Spatial context is a concept of great interest to social scientists as they try to understand how behavior is determined by an individual's surroundings. Obesity, drug use, housing segregation, and many other aspects of human behavior depend to some degree on the environment in which the individual lives, and yet much previous research has failed to find accurate ways of capturing spatial context. An individual's ZIP code, for example, is often taken as a convenient but necessarily inacccurate basis for estimating the spatial factors that influence behavior. This book will be helpful to researchers interested in finding better solutions to the problem of characterizing spatial context.
