Rufus for linux? Not available, Use these best alternatives

Rufus for Linux, yes, everybody who has ever used this bootable USB creator tool which is only available for Windows, definitely wished to have it for Linux operating systems too. However, although it is not directly available for Linux, we can still use it with the help of Wine software. But again even after installing it using Wine on Ubuntu, in our case, it couldn’t recognize the attached USB drives, which again closed the door for normal users to use Rufus on Linux. Thus in such scenarios what do? Don’t worry. The Rufus is not the only software for creating a bootable USB drives in the world. There are also few other best alternatives to Rufus that we can use easily on Linux operating systems. And here today we will discuss such opensource or free tools for creating bootable drives on Linux Distros.

5 Reasons Purism's Librem Laptops Are More Secure Than Your Notebook

If you're looking for a secure laptop computer, you have several options. Thumb readers, facial recognition, and built-in encryption all offer considerable security. But these features – typically backed up by the operating system – are prone to failure, one way or another. For example, facial recognition can be bypassed using various techniques. Purism is a company that assembles Linux computers, complete with a secure operating system and hardware kill switches. These features – while eschewing potential points of entry found on other laptops – make Purism laptops particularly attractive to any user concerned about online privacy and security.

• Repurposing the VFD unit from an old Epson POS display using Arduino | Arduino Blog

  For many makers, it’s always fun to take some piece of old technology and give it a new lease on life, especially when the item in question was destined for the landfill. This is what prompted Alastair Aitchison — better known on YouTube as Playful Technology — to grab a deprecated vacuum fluorescent display (VFD) module from an Epson point-of-sale device and interface it with an Arduino Nano as a real-time display. VFDs can be thought of as character LCDs, but rather than having many dot-matrix units that use the alignments of suspended crystals to block light, tiny phosphor crystals light up when a current is applied. The module isn’t driven directly by the Arduino Nano since it requires a far higher voltage so a special display controller chip is integrated, which receives commands/data over an RS-232 port and manipulates the onscreen graphics accordingly. This meant a MAX232 had to be used to convert the Nano’s 5V TTL voltage into the -15V to 15 range.

• [IBM's IWB:] Why Our Judgements Are Often Flawed and What to Do About It

  A few weeks ago I listened to a very interesting Freakonomics podcast hosted by University of Chicago economist Steven Levitt. In the podcast, Why Our Judgment is Flawed — and What to Do About It, Levitt interviewed Daniel Kahneman about his recent book, Noise: A Flow in Human Judgement, co-authored with Olivier Sibony and Cass Sunstein. Kahneman is Professor of Psychology and Public Affairs Emeritus at Princeton University. In 2002, he was awarded the Nobel Prize in Economics “for having integrated insights from psychological research into economic science, especially concerning human judgment and decision-making under uncertainty.” Thinking, Fast and Slow, Kahneman’s 2011 bestseller, was about the major discoveries by psychologists and cognitive scientists that have led to our current understanding of judgement and decision-making over the past several decades. Up to the 1970s, the prevailing view among social scientists was that people are generally rational and in control of the way they think and make decisions. It was thought that people only departed from rational behaviors because powerful emotions like fear, hatred or love distorted their judgement. These assumptions were challenged by the pioneering research of Kahneman and his long time collaborator Amos Tversky, who died in 1996. In a series of experiments, they demonstrated that human behavior often deviated from the predictions of the previous rational models, and that these deviations were due to the machinery of cognition, that is, to the biases and mental shortcuts or heuristics that we use for making everyday decisions, rather than to our emotional state.

• Running the AWSY benchmark in the Firefox profiler — Paul Bone

  The are we slim yet (AWSY) benchmark measures memory usage. Recently when I made a simple change to firefox and expected it might save a bit of memory, it actually increased memory usage on the AWSY benchmark. We have lots of tools to hunt down memory usage problems. But to see an almost "log" of when garbage collection and cycle collection occurs, the Firefox profiler is amazing. I wanted to profile the AWSY benchmark to try and understand what was happening with GC scheduling. But it didn’t work out-of-the-box. This is one of those blog posts that I’m writing down so next time this happens, to me or anyone else, although I am selfish. And I websearch for "AWSY and Firefox Profiler" I want this to be the number 1 result and help me (or someone else) out. The normal instructions

• World Free Software Day: why it is celebrated today and what are the advantages of these programs [Ed: Automated translation]

  Linux, Firefox, WordPress and even the very popular Android are, each in their own way, examples of the software free. Today is celebrating the move that involves a specific way of distributing and using computer programs: just like every third Saturday in September since the Free Software Day. The event arose in 2004 and on the occasion it was held on August 28, but around 2006 the third Saturday of the ninth month of the year was set.
