Efficiently

I’ve tested these fundamentals to prove they can be used to lay the foundation for a successful self-learning experiencePhoto by Ahmer Kalam on UnsplashSelf-teaching yourself anything is an admirable undertaking.Whether it’s a new language, baking, weightlifting, structural geology, basket weaving, driving manual transmission vehicles, or anything else you can think of, I have insane amounts of respect for anyone who decides they’re going to teach themselves something.When someone tells me they’re going to self-teach…

One day it could help countries emerge from the shadows of pandemics by killing pathogens in…

Efficient reversal of lists in PythonPhoto by 愚木混株 cdd20 on UnsplashLists are among the fundamental and most commonly used data structures in Python. A list is a mutable and ordered collection of objects that can also store duplicate values. They can even be used as queues and stacks (even though deque might be more efficient).List reversal is a fairly common task performed by developers when writing Python applications. In today’s short tutorial we will demonstrate a few different ways for reversing a list and also…

Learn different ways to insert large numbers of records into the database efficiently in PythonImage by PublicDomainPictures in PixabayIt’s very convenient to use SQLAlchemy to interact with relational databases with plain SQL queries or object-relational mappers (ORM). However, when it comes to bulk inserts, namely, inserting a large number of records into a table, we may often have performance issues. In this post, we will introduce different ways for bulk inserts and compare their performances through a hands-on…

Discarded electronics can be a gold mine – literally. Researchers have developed an efficient new way to use graphene to recover gold from electronic waste, without needing any other chemicals or energy.Beyond its superficial uses in jewelry, gold is prized for use in electronic components thanks to its high electrical conductivity and ease to work with. But electronic devices have a high turnover, and recovering gold and other precious metals is a process that’s often fiddly, inefficient, and requires chemicals or high…

Water gets boiled a lot – whether it's a cup of tea brewing in a kitchen or a power plant generating electricity. Any improvements in the efficiency of this process will have a huge impact on the overall amount of energy used for it every day.  One such improvement could come with a newly developed treatment for surfaces involved in heating and evaporating water. The treatment improves two key parameters that determine the boiling process: the heat transfer coefficient (HTC) and the critical heat flux (CHF).Most of the…

The MacOS file manager, Finder, has a lot of handy tricks up its sleeve, many of which are there to help you work more efficiently. One such feature has been around since MacOS Mojave and makes it easy to act on files within Finder. That feature is called Quick Actions and presents a right-click (or two-finger tap) context menu for files and folders within Finder.This context menu changes based on the file or folder you're working with. For example, if you right-click an image, you can quickly convert it to a different…

Scientists have improved on the natural process of photosynthesis, not only growing plants more efficiently, but doing so in the dark. This could expand agriculture to areas that don’t get enough sunlight, and even help feed future space explorers.As you may recall from elementary school science class, photosynthesis is where plants absorb energy from sunlight and use it to create their own food from carbon dioxide and water. The process has helped plants – and by extension, life on Earth – thrive for billions of years,…

MIT engineers demonstrated that analog-to-digital converters in smart devices are vulnerable to power and electromagnetic side-channel attacks that hackers use to “eavesdrop” on devices and steal secret information. They developed two security strategies that effectively and efficiently block both types of attacks.

In the telecom industry, proper connectivity is the most important foundation. Especially today, in times of online globalization, the amount of different devices exchanging information with each other is tremendous. And that provides a lot of problems to deal with. IoT Connect was design to manage this process. Care to learn more? The basics Right on the start, we should explain the term itself. The Internet of Things (IoT) is a concept by which clearly identifiable objects can directly or indirectly collect,…
