Git is an open source freely distributed version control system specifically designed to efficiently handle all aspects of your project. It’s relatively small learning curve combined with its tiny footprint and outstanding performance have made it a favorite among programmers for collaboratively developing source code during application development. Unlike most client-server systems, Git directories are full-fledged repositories with complete history and full version-tracking abilities, independent of network access or a central server.
Below are some handy git commands to help you stay on task when developing amazing applications!
On September 9, 1947, a Harvard technical team found that their computer, the Harvard Mark II, was consistently delivering errors. Upon inspection, they isolated the issue to an electromagnetic relay. And as the story goes, the first reported debugging of a computer system by a team of professional experts resulted in the discovery of an actual bug. A moth to be precise — that got trapped between the points of Relay 70 in panel F of their pioneering electromechanical computer disrupting the internal electronics to such a degree that the computer was unable to deliver consistent and accurate results.
Considered a simple sorting algorithm, insertion sort is not without its merits. While not as efficient as more advanced algorithms when scaled, it is a stable algorithm in that it does not change the relative order of elements with equal values. It is also an excellent choice when you have to continually add new data as it is received. This is because it only needs to do one pass to determine proper placement and on smaller or mostly sorted arrays or lists, this algorithm will actually outperform some of the more complex algorithms.
Insertion sort iterates through an array or…
Merge Sort is an extremely popular sorting algorithm that combines merging and sorting exploiting the fact that empty or single element arrays are considered sorted. When scaled, this algorithm offers significant performance gains relative to less advanced sorting algorithms like Bubble Sort or Selection Sort. It is a member of the “divide and conquer” algorithm family that approach problem solving through deconstruction of a problem into smaller problems simple enough to solve directly with solutions that can then be collectively applied toward the original problem.
Merge sort recursively splits an array into smaller empty or single element arrays that are…
Binary search is a commonly used algorithm offering a more efficient form of search than a traditional linear search. Instead of iterating through an array eliminating one element at a time, you can eliminate half of the remaining elements at a time. However, it only works with sorted arrays and ordered lists.
A binary search starts in the middle of an array and checks if that value is greater than, less than, or equal to the value you are looking for. If that element is greater, the algorithm now knows to continue searching in the left half of the array…
bcrypt is an excellent tool for shoring up password protection and user authentication in your Ruby on Rails application.
Proper user authentication and password protection are a must for any application seeking to restrict content or collect sensitive user information. With identity theft negatively impacting millions of individuals each year, data breaches could prove detrimental not only to the user but also to the platform. A single data breach has the potential to erode public trust and confidence and depending on the breach, open the door to liability. Avast recently reported that 90% of online users worry about compromised passwords…
