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.

Unique Clock Doubles as a Development Board

Most clocks these days have ditched the round face and instead prefer to tell time through the medium of 7-segment displays. [mihai.cuciuc] is bringing the round face to digital clocks with his time-keeping piece, MakeTime.

[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.

AMD + Valve Focusing On P-State / CPPC Driver With Schedutil For Better Linux Efficiency - Phoronix

As reported at the start of August, AMD and Valve have been working on Linux CPU performance/frequency scaling improvements with the Steam Deck being one of the leading motivators. As speculated at that time, their work would likely revolve around use of ACPI CPPC found with Zen 2 CPUs and newer. Published last week was that AMD P-State driver for Linux systems indeed now leveraging CPPC information. AMD formally presented this new driver yesterday at XDC2021.

DRM Driver Posted For AI Processing Unit - Initially Focused On Mediatek SoCs - Phoronix

BayLibre developer Alexandre Bailon has posted a "request for comments" of a new open-source Direct Rendering Manager (DRM) driver for AI Processing Unit (APU) functionality. Initially the driver is catering to Mediatek SoCs with an AI co-processor but this DRM "APU" driver could be adapted to other hardware too. Alexandre Bailon sums up this DRM AI Processing Unit driver as "a DRM driver that implements communication between the CPU and an APU. This uses VirtIO buffer to exchange messages. For the data, we allocate a GEM object and map it using IOMMU to make it available to the APU. The driver is relatively generic, and should work with any SoC implementing hardware accelerator for AI if they use support remoteproc and VirtIO."

Apple M1 USB Type-C Linux Support Code Sent Out For Testing - Phoronix

he latest patches sent out for review/testing on the long mission for enabling Apple M1 support on Linux is the USB Type-C connectivity. Sven Peter has sent out the initial USB Type-C enablement work for the Apple ACE1/2 chips used by Apple M1 systems. In turn this Apple design is based on the TI TPS6598x IP but various differences. The Linux kernel support is being added onto the existing TIPD driver.

Sioyek: A PDF Reader For Researchers?? - Invidious

Today we're looking at an odd PDF reader, it's not just intended to be used for regular PDFs, obviously it works great for that. But where it shines is working with research papers and provides a few interesting functions to make that easier.

Give Boring Video Cinematic Color Grading With LUTs - Invidious

In recent weeks, I've been playing around a bit with color grading my videos. One of the neat things that I've discovered are LUTs (look-up tables) which are templates that can be applied to videos (and images) to add color grading effects.
