Nushell, or Nu for short, is a new shell that takes a modern, structured approach to your commandline. It works seamlessly with the data from your filesystem, operating system, and a growing number of file formats to make it easy to build powerful commandline pipelines.
Today, we’re releasing a beta release of 0.60 of Nu. This is an enormous release, with lots of changes across all aspects of Nushell.
System sidesteps computing bottleneck in tuning artificial intelligence algorithms
A simple electrical circuit has learned to recognize flowers based on their petal size. That may seem trivial compared with artificial intelligence (AI) systems that recognize faces in a crowd, transcribe spoken words into text, and perform other astounding feats. However, the tiny circuit outshines conventional machine learning systems in one key way: It teaches itself without any help from a computer—akin to a living brain. The result demonstrates one way to avoid the massive amount of computation typically required to tune an AI system, an issue that could become more of a roadblock as such programs grow increasingly complex.
I’ve been programming since 1999 and this year I’ve officially coded for 20+ years. I started with Basic but soon jumped into Pascal and C and then learned object oriented programming (OOP) with Delphi and C++. In 2006 I started with Java and in 2011 I started with JavaScript. I’ve worked with a wide range of businesses from robotics, fin tech, med tech to media and telecom. Sometimes I had a different hat as a researcher, CTO, TPM (technical product manager), teacher, system architect or TL (technical leader) but I’ve always been coding. I’ve worked on some products that served millions of people, and some that failed before being released. I worked as a consultant and I even had my own startup. I have spent lots of time on open source projects, closed source projects and internally open source projects (proprietary code that is developed by a community inside the company). I’ve worked with tiny microcontrollers all the way to mobile and desktop apps to cloud servers and lately serverless.
JDK 18, the reference implementation of Java 18, is now Generally
Available. We shipped build 36 as the first Release Candidate of
JDK 18 on 15 February, and no P1 bugs have been reported since then.
Build 36 is therefore now the GA build, ready for production use.
Has announced plans to build a world first plant in South Wales to recover gold from UK electronic waste. The pioneering facility will help address a growing environmental issue, support jobs and skills in Britain, and create a new source of high quality precious metals for the business.
The Royal Mint is using patented new chemistry – created by Canadian based Excir – to recover gold within the circuit boards of laptops and mobile phones. The unique chemistry is capable of recovering over 99% of the precious metals contained within electronic waste – selectively targeting the metal in seconds.
Construction of the plant begins this month, and it will be located within The Royal Mint’s highly secure site to provide a stream of gold directly into the business. When fully operational in 2023, The Royal Mint expects to process up to 90 tonnes of UK-sourced circuit boards per week – generating hundreds of kilograms of gold per year. In addition, the new business venture will support around 40 jobs, helping existing employees to reskill as well as recruiting new chemists and engineers.
Agreement will enable OneWeb to resume its launch programme and complete satellite constellation for industry-grade secure connectivity around the world.
OneWeb, the low Earth orbit (LEO) satellite communications company, announced today that the company and SpaceX entered into an agreement that will enable OneWeb to resume satellite launches.
The first launch with SpaceX is anticipated in 2022 and will add to OneWeb’s total in-orbit constellation that currently stands at 428 satellites, or 66 percent of the fleet. OneWeb’s network will deliver high-speed, low-latency global connectivity.
We introduce LTrack, a new tracking attack on LTE that allows an attacker to stealthily extract user devices’ locations and permanent identifiers (IMSI). To remain stealthy, the localization of devices in LTrack is fully passive, relying on our new uplink/downlink sniffer. Our sniffer records both the times of arrival of LTE messages and the contents of the Timing Advance Commands, based on which LTrack calculates locations. LTrack is the first to show the feasibility of a passive localization in LTE through implementation on software-defined radio.
A gravity hill, also known as a magnetic hill, mystery hill, mystery spot, gravity road, or anti-gravity hill, is a place where the layout of the surrounding land produces an optical illusion, making a slight downhill slope appear to be an uphill slope. Thus, a car left out of gear will appear to be rolling uphill against gravity.[1] There are hundreds of recognized gravity hills around the world.
A Gömböc is a strange thing. It looks like an egg with sharp edges, and when you put it down it starts wriggling and rolling around with an apparent will of its own. Until quite recently, no-one knew whether Gömböcs even existed. Even now, Gábor Domokos, one of their discoverers, reckons that in some sense they barely exists at all. So what are Gömböcs and what makes them special?
Apple’s first product was the Apple-1 computer, introduced in 1976. This early microcomputer used an unusual type of storage for its display: shift register memory. Instead of storing data in RAM (random-access memory), it was stored in a 1024-position shift register. You put a bit into the shift register and 1024 clock cycles later, the bit pops out the other end. Since a shift-register memory didn’t require addressing circuitry, it could be manufactured more cheaply than a random-access memory chip.1 The downside, of course, is that you had to use bits as they became available, rather than access arbitrary memory locations. The behavior of shift-register memory was a good match for video circuitry, though, since characters are displayed on the screen in a fixed, repeating order (left to right and top to bottom).
