A curated list of websites with beautiful free icon design sets that can be used for personal and commercial projects.

Stretched for time, some households are starting to operate more like businesses.

Steven Rostedt wanted to do a little housekeeping, specifically with the function tracing code used in debugging the kernel. Up until then, the kernel could enable function tracing using either GCC's -pg flag or a combination of -pg and -mfentry. In each case, GCC would create a special routine that would execute at the start of each function, so the kernel could track calls to all functions. With just -pg, GCC would create a call to mcount() in all C functions, although with -pg coupled with -mfentry, it would create a call to fentry().

fd, is a simple, fast and user-friendly tool meant to simply perform faster compared to find, but it not meant to completely replace find, but rather provide a better performance.

A simple walkthrough of what RNNs are, how they work, and how to build one from scratch in Python.

A couple of years back, even researchers would wave off using DNA to store data as something too futuristic to have any practical value. Today, you can extend PostgreSQL with the right software and bio-chemical modules, and run SQL on DNA.

A communication system built on MQTT consists of the publishing server, a broker and one or more clients. The publisher does not require any configuration concerning the number or location of subscribers receiving messages. Likewise, subscribers do not need publisher-specific setup. There may be more than one broker on the system distributing messages.

This article explains how to edit PDF metadata tags on Linux, using either a GUI or from the command line.

Great features are in store for those who truly learn the editor

For the past few years, I've been building and operating a large distributed system: the payments system at Uber. I've learned a lot about distributed architecture concepts during this time and seen first-hand how high-load and high-availability systems are challenging not just to build, but to operate as well.

In this guide, we will discuss four unofficial google drive clients for Linux. Using them, you can mount Google drive locally as a virtual file system.

The outputs from scientific research are many and varied, including: research articles reporting new knowledge, data, reagents, and software; intellectual property; and highly trained young scientists. Funding agencies, institutions that employ scientists, and scientists themselves, all have a desire, and need, to assess the quality and impact of scientific outputs. It is thus imperative that scientific output is measured accurately and evaluated wisely.

Say you have an external hard drive with layers upon layers of cryptically named folders and intricate mazes of directories (like here, or here). How can you make sense of this mess? Python offers various tools in the Python standard library to deal with your file system and the folderstats module can be of additional help to gain insights into your file system.

In this article, you will learn the various ways to traverse and explore the file system with Python. In the next section, you will see how to extract statistics from files and directories. In the last section, you will see a practical way to analyze folder structures with folderstats and Pandas with some use cases and visualizations along the way.

The automobile took over because the legal system helped squeeze out the alternatives.

Scientists used machine learning to reveal new scientific knowledge hidden in old research papers.

Using just the language in millions of old scientific papers, a machine learning algorithm was able to make completely new scientific discoveries.

In a study published in Nature on July 3, researchers from the Lawrence Berkeley National Laboratory used an algorithm called Word2Vec sift through scientific papers for connections humans had missed. Their algorithm then spit out predictions for possible thermoelectric materials, which convert heat to energy and are used in many heating and cooling applications.
