Introduction To Web Applications: Part 1


It is hardly surprising that web applications have seen such an impressive development over the course of the last approximately ten years. If one were to make a synthesis of the overall experience of desktop applications, there are a couple of valid arguments that we can be almost certain would appear. First and foremost, a piece of desktop software has to be manually retrieved (downloaded from the Internet or physically) and installed, which can present issues to the "non-technical" user. Needless to say that this process can bring, and mostly has, subsequent issues in regards to updating and/or patching the software, system requirements, etc. Also, cross-platform development efforts are needed in order to provide versions for the three major operating systems (macOS, Windows, Linux) if the target is to reach as large of an audience as possible. Desktop applications used to be bound to the machine in terms of the licensing as well, which further reduced the flexibility in approaching one's work. A further valid point has to do with the limited, often delayed, user feedback and how that can lead to the diminishing of testing scenarios. Of course no solution is constructed out of disadvantages alone and we are not dealing with such a case here, either: desktop applications tend to be faster and are generally considered more secure than their web counterparts. However, history has shown that while the web is not the perfect solution, its advantages were simply too powerful to ignore. Not only does a web application require no installation from the user, updates can be easily rolled out and made available to all users instantly after a new release.

Anyone Can Download An Autonomous 'Research Robot' From The Air Force Research Laboratory


Dr. Benji Maruyama is the Air Force Research Laboratory team lead for Autonomous Materials and the ... [ ] Autonomous Research System also known as ARES. ARES OS, an open-source software program, is now available online as a free download. In the fight to prevail over America's adversaries by out-innovating them - a fight which has all the hallmarks of a Cold War despite President Biden's assertions to the contrary - increasing the speed at which physical lab experiments can be done and iterated is vital. Air Force Research Laboratory (AFRL) scientist, Dr. Benji Maruyama, is reminding his peers and the public that, "Research is a painfully slow process. Being in a lab and doing experiments takes lots of time."

Try These 5 Tips To Optimize Your Python Code


Python is famous for its amazing libraries that are available for almost any field of computer science and you should take the advantage of them. Some built-in functions in Python like map(), sum(), max() etc are already implemented in C so they are not interpreted during the execution which saves a lot of time. For example, If you want to convert a string into a list you can do that using the map() function instead of appending the contents of the strings into a list manually. The code is more optimized and smaller in size too. You can find many more similar cool functions available on python that can make your task easy and optimized.

A New Era for Mechanical CAD

Communications of the ACM

Computer-Aided Design (CAD) has been around since the 1950s. The first graphical CAD program, called Sketchpad, came out of MIT ( Since then, CAD has become essential to designing and manufacturing hardware products. Today, there are multiple types of CAD. This article focuses on mechanical CAD, used for mechanical engineering. Digging into the history of computer graphics reveals some interesting connections between the most ambitious and notorious engineers. Ivan Sutherland, who received the Turing Award for Sketchpad in 1988, had Edwin Catmull as a student.
