Microsoft 'Re-Open Sources' MS-DOS on GitHub

by EditorDavid
An anonymous reader quotes Microsoft's Developer blog: In March 2014, Microsoft released the source code to MS-DOS 1.25 and 2.0 via the Computer History Museum. The announcement also contains a brief history of how MS-DOS came to be for those new to the subject, and ends with many links to related articles and resources for those interested in learning more. Today, we're re-open-sourcing MS-DOS on GitHub. Why? Because it's much easier to find, read, and refer to MS-DOS source files if they're in a GitHub repo than in the original downloadable compressed archive file.... Enjoy exploring the initial foundations of a family of operating systems that helped fuel the explosion of computer technology that we all rely upon for so much of our modern lives! While non-source modifications are welcome, "The source will be kept static," reads a note on the GitHub repo, "so please don't send Pull Requests suggesting any modifications to the source files." "But feel free to fork this repo and experiment!"

Tim Berners-Lee Announces Solid, an Open Source Project Which Would Aim To Decentralize the Web

by msmash
Tim Berners-Lee, the founder of the World Wide Web, thinks it's broken and he has a plan to fix it. The British computer scientist has announced a new project that he hopes will radically change his creation by giving people full control over their data. Tim Berners-Lee: This is why I have, over recent years, been working with a few people at MIT and elsewhere to develop Solid, an open-source project to restore the power and agency of individuals on the web. Solid changes the current model where users have to hand over personal data to digital giants in exchange for perceived value. As we've all discovered, this hasn't been in our best interests. Solid is how we evolve the web in order to restore balance -- by giving every one of us complete control over data, personal or not, in a revolutionary way. Solid is a platform, built using the existing web. It gives every user a choice about where data is stored, which specific people and groups can access select elements, and which apps you use. It allows you, your family and colleagues, to link and share data with anyone. It allows people to look at the same data with different apps at the same time. Solid unleashes incredible opportunities for creativity, problem-solving and commerce. It will empower individuals, developers and businesses with entirely new ways to conceive, build and find innovative, trusted and beneficial applications and services. I see multiple market possibilities, including Solid apps and Solid data storage. Solid is guided by the principle of "personal empowerment through data" which we believe is fundamental to the success of the next era of the web. We believe data should empower each of us. Imagine if all your current apps talked to each other, collaborating and conceiving ways to enrich and streamline your personal life and business objectives? That's the kind of innovation, intelligence and creativity Solid apps will generate. With Solid, you will have far more personal agency over data -- you decide which apps can access it. In an interview with Fast Company, he shared more on Solid and its creation: "I have been imagining this for a very long time," says Berners-Lee. He opens up his laptop and starts tapping at his keyboard. Watching the inventor of the web work at his computer feels like what it might have been like to watch Beethoven compose a symphony: It's riveting but hard to fully grasp. "We are in the Solid world now," he says, his eyes lit up with excitement. He pushes the laptop toward me so I too can see. On his screen, there is a simple-looking web page with tabs across the top: Tim's to-do list, his calendar, chats, address book. He built this app -- one of the first on Solid -- for his personal use. It is simple, spare. In fact, it's so plain that, at first glance, it's hard to see its significance. But to Berners-Lee, this is where the revolution begins. The app, using Solid's decentralized technology, allows Berners-Lee to access all of his data seamlessly -- his calendar, his music library, videos, chat, research. It's like a mashup of Google Drive, Microsoft Outlook, Slack, Spotify, and WhatsApp. The difference here is that, on Solid, all the information is under his control. Every bit of data he creates or adds on Solid exists within a Solid pod -- which is an acronym for personal online data store. These pods are what give Solid users control over their applications and information on the web. Anyone using the platform will get a Solid identity and Solid pod. This is how people, Berners-Lee says, will take back the power of the web from corporations. Starting this week, developers around the world will be able to start building their own decentralized apps with tools through the Inrupt site. Berners-Lee will spend this fall crisscrossing the globe, giving tutorials and presentations to developers about Solid and Inrupt. "What's great about having a startup versus a research group is things get done," he says. These days, instead of heading into his lab at MIT, Berners-Lee comes to the Inrupt offices, which are currently based out of Janeiro Digital, a company he has contracted to help work on Inrupt. For now, the company consists of Berners-Lee; his partner John Bruce, who built Resilient, a security platform bought by IBM; a handful of on-staff developers contracted to work on the project; and a community of volunteer coders. Later this fall, Berners-Lee plans to start looking for more venture funding and grow his team. The aim, for now, is not to make billions of dollars. The man who gave the web away for free has never been motivated by money. Still, his plans could impact billion-dollar business models that profit off of control over data. It's not likely that the big powers of the web will give up control without a fight.

Study Links Restricting Screen Time For Kids To Higher Mental Performance

by msmash
Parents who possess the resolve to separate their children from their smartphones may be helping their kids' brainpower, a new study suggests. A report adds: Children who use smartphones and other devices in their free time for fewer than two hours a day performed better on cognitive tests assessing their thinking, language, and memory, according to a study published this week in the Lancet Child & Adolescent Health. The study assessed the behavior of 4,500 children, ages 8 to 11, by looking at their sleep schedules, how much time they spent on screens and their amount of exercise, and analyzed how those factors impacted the children's mental abilities. The researchers compared the results with national guidelines for children's health. The guidelines recommend that children in that age group, get at least an hour of physical activity, no more than two hours of recreational screen time and nine to 11 hours of sleep per night. The researchers found that only 5 percent of children met all three recommendations. Sixty-three percent of children spent more than two hours a day staring at screens, failing to meet the screen-time limit.

Famed Mathematician Claims Proof of 160-Year-Old Riemann Hypothesis

by BeauHD
Slashdot reader OneHundredAndTen writes: Sir Michael Atiyah claims to have proved the Riemann hypothesis. This is not some internet crank, but one the towering figures of mathematics in the second half of the 20th century. The thing is, he's almost 90 years old. According to New Scientist, Atiyah is set to present his "simple proof" of the Riemann hypothesis on Monday at the Heidelberg Laureate Forum in Germany. Atiyah has received two awards often referred to as the Nobel prizes of mathematics, the Fields medal and the Abel Prize; he also served as president of the London Mathematical Society, the Royal Society and the Royal Society of Edinburgh. "[T]he hypothesis is intimately connected to the distribution of prime numbers, those indivisible by any whole number other than themselves and one," reports New Scientist. "If the hypothesis is proven to be correct, mathematicians would be armed with a map to the location of all such prime numbers, a breakthrough with far-reaching repercussions in the field."

Titans of Mathematics Clash Over Epic Proof of ABC Conjecture

by msmash
Two mathematicians have found what they say is a hole at the heart of a proof that has convulsed the mathematics community for nearly six years. Quanta Magazine: In a report [PDF] posted online Thursday, Peter Scholze of the University of Bonn and Jakob Stix of Goethe University Frankfurt describe what Stix calls a "serious, unfixable gap" within a mammoth series of papers by Shinichi Mochizuki, a mathematician at Kyoto University who is renowned for his brilliance. Posted online in 2012, Mochizuki's papers supposedly prove the abc conjecture, one of the most far-reaching problems in number theory. Despite multiple conferences dedicated to explicating Mochizuki's proof, number theorists have struggled to come to grips with its underlying ideas. His series of papers, which total more than 500 pages, are written in an impenetrable style, and refer back to a further 500 pages or so of previous work by Mochizuki, creating what one mathematician, Brian Conrad of Stanford University, has called "a sense of infinite regress." Between 12 and 18 mathematicians who have studied the proof in depth believe it is correct, wrote Ivan Fesenko of the University of Nottingham in an email. But only mathematicians in "Mochizuki's orbit" have vouched for the proof's correctness, Conrad commented in a blog discussion last December. "There is nobody else out there who has been willing to say even off the record that they are confident the proof is complete." Nevertheless, wrote Frank Calegari of the University of Chicago in a December blog post, "mathematicians are very loath to claim that there is a problem with Mochizuki's argument because they can't point to any definitive error." That has now changed. In their report, Scholze and Stix argue that a line of reasoning near the end of the proof of "Corollary 3.12" in Mochizuki's third of four papers is fundamentally flawed. The corollary is central to Mochizuki's proposed abc proof. "I think the abc conjecture is still open," Scholze said. "Anybody has a chance of proving it."

Humans Simply 'Hardwired' For Laziness, Study Says

by BeauHD
Zorro shares a report from Study Finds: [...] A new study shows we may just have to chalk it up to our brains simply being hardwired to prefer hanging on the couch instead of the chin-up bar. Researchers from the University of British Columbia and University of Geneva sought to better understand the brain chemistry behind what they refer to as the "exercise paradox." This happens when people pledge to engage in regular physical fitness, but instead find themselves becoming less active. "Conserving energy has been essential for humans' survival, as it allowed us to be more efficient in searching for food and shelter, competing for sexual partners, and avoiding predators," explains Matthew Boisgontier, a postdoctoral researcher in UBC's brain behavior lab at the department of physical therapy, and senior author of the study, in a UBC release. So Boisgontier and his co-authors recruited 29 young adults who wanted to improve the level of exercise in their lives to take part in a computerized test. The test required them to move a human figure on the screen either towards images of physical activities or away from images of sedentary activities that would randomly appear, and then again vice versa. Participants were hooked up to an electroencephalograph to monitor their brain activity during the exercise. The results showed that participants tended to move towards the active images or away from the sedentary ones at the fastest rates. "We found that participants took 32 milliseconds less to move away from the sedentary image, which is considerable for a task like this," says study co-author Boris Cheval, of the University of Geneva, in a university release, adding that this finding went against the so-called exercise paradox.

The Linux Foundation Is Changing The Fabric Of Networking

by msmash
Will Townsend, a senior analyst at Moor Insights & Strategy research firm, writes: As it relates to networking, the Linux Foundation is currently focused on a number of projects that are bringing top networking vendors, operators, service providers, and users together. Among the top initiatives are the Open Network Automation Platform (ONAP) and Data Plane Development Kit (DPDK). In this article, I would like to dive into both of these initiatives and share my perspective on how each is transforming the nature of networking [Editor's note: the website may have auto-playing videos; an alternative link was not available]. It makes sense that ONAP's releases are named after global cities, considering the platform's growing global footprint. ONAP is aimed at bringing real-time automation and orchestration to both physical and virtualized network functions. The first release in the fall of 2017, named Amsterdam, delivered a unified architecture for providing closed-loop networking automation. The underlying framework ensured a level of modularity to facilitate future functionality as well as standards harmonization and critical upstream partner collaboration. Initial use cases centered on Voice Over LTE (VoLTE) services as well as Virtualized Consumer Premise Equipment (vCPE). Both are extremely cost disruptive from a deployment and management perspective and deliver enhanced service provider agility. What I find extremely compelling is that Amsterdam was only an eight-month development cycle from start to release. That's an amazing feat even in the fast-paced technology industry. [...] DPDK was an effort initially led by Intel at its inception nearly eight years ago, but became a part of the Linux Foundation back in 2017. At a high level, the technology accelerates packet processing workloads running on a variety of CPU architectures. DPDK is aimed at improving overall network performance, delivering enhanced encryption for improved security and optimizing lower latency applications that require lightning-fast response time. The transformative power of 5G networks lies in their potential to deliver low latency for applications such as augmented/virtual reality and self-driving cars -- DPDK will further extend that performance for next-generation wireless wide area networks. I had the opportunity recently to speak to project chair Jim St. Leger after the fifth DPDK release, and I was impressed with the depth and breadth of the open source project. Over 25 companies and 160 technologists are involved in advancing the effort. With the proliferation of data, cord cutting at home, and growing consumption of video over wired and wireless networks, high-quality compression techniques will dramatically improve performance and reliability. DPDK appears to be poised to contribute significantly to that effort.

Linux Distro Elive Emerges Alive After 8-Year Hibernation

by msmash
Designed to run on minimal hardware, Elive is very much a passion project of its leader, Samuel F Baggen. Based on Debian, the first version took a bow in 2005. The second stable version made an appearance in 2010 and it has been a long eight years for the third stable version to become available. The Register: Elive has an impressively low bar to entry, with hardware requirements for the distribution coming in at 256 MB RAM and a 500 MHz CPU, meaning that some very elderly silicon is theoretically going to be able to enjoy the highly polished Enlightenment desktop. "Theoretically" because after The Register took Elive 3.0.0 out for a spin on a relatively low-powered laptop, we'd frankly baulk at running it on anything much slower than a 533MHz Core 2 with at least 512 MB RAM. However, the Enlightenment UI is undeniably an attractive desktop, particularly if a macOS-alike dock is your thing, and runs at an impressive lick even on hardware that lacks graphics acceleration. At its core, Elive is based on the Debian 8 distribution (aka Jessie), using the 3.16 kernel and version 0.17.6 of the Enlightenment X11 Window Manager. It comes replete with a full set of applications, including the ubiquitous LibreOffice and Gimp, along with a variety of productivity and entertainment tools, some of which are Elive's own. Unlike the previous version of Elive, 3.0.0 removes the requirement of donating to the project in order to install the thing locally (although Baggen was quick to tell The Reg that cost-free alternatives existed, but often with annoying processes).

Назад в изгубеното време

by Evgeni

Отвъд забързаното ежедневие на градския живот, където стрелките на часовника се въртят неумолимо, съществуват потънали в забвение малки села, захвърлени в затънтени крайчета на родината. Там времето заникъде не бърза. Спряло е, да си почине.

Всяко лято от десетина години насам не пропускам да намина към язовирите Голям Беглик или Широка Поляна. Докато преди се дивях на страхотните изпарения рано утрин и обикалях като гламав насам-натам, за да запечатам някой страхотен момент, сега просто се наслаждавам на уединението.

golyambeglik

Би ми било съвестно, ако не стана рано поне една сутрин и не се помотая наоколо, докато всички все още дремят.

Голям Беглик огрян в златна светлина

Еуфорията да запечатвам стотици кадри сред този пленителен пейзаж се е изпарила през годините. Наблюдавам как изгряващото слънце озарява в златно боровата гора, без да се чувствам длъжен да заснема всяка една секунда от този приказен момент.

Колкото и да е малка България, все още се намират места, до които не съм успял да се докосна. Такива са например околностите на Хаджидимово, които биха наподобявали Тоскана, стига земята да беше обработена така прилежно.

New Computer System Helps Slash Cholera Cases in Yemen By Predicting Where Outbreaks Will Occur

by msmash
Cholera cases in Yemen have been slashed by a new system that predicts where outbreaks will occur. From a report: Last year, there were more than 50,000 new cases in just one week -- this year, the numbers plummeted to about 2,500. The system has enabled aid workers to focus efforts on prevention several weeks in advance of an outbreak -- by monitoring rainfall. It comes as the UN says it is concerned about a possible "third wave" of the epidemic. The deployment of the technology has been coordinated by the UK's Department for International Development. [...] The UK's overseas aid department has worked with the Met Office to develop a system that predicts where cholera will occur four weeks ahead of time. The Met Office produces a rainfall forecast for Yemen. Using its supercomputers, it is to determine the specific amount of rain that will fall and pinpoint the areas it will hit within a 10km (six-mile) radius. These are important because downpours overwhelm the sewerage system and spread the infection. The forecasts are used in conjunction with a computer model developed by Prof Rita Colwell, at the University of Maryland, and Dr Antar Jutla, at West Virginia University. Together, this information enables scientists to predict the areas most likely to experience an outbreak, up to four weeks in advance.

Windows 95 Is Now An App You Can Download and Install On macOS, Windows, and Linux

by BeauHD
Rtersieva

yey ;)

Slack developer Felix Rieseberg has made Windows 95 into an electron app that you can run on macOS, Windows, and Linux. The source code and app installers are available on GitHub. According to The Verge, "apps like Wordpad, phone dialer, MS Paint, and Minesweeper all run like you'd expect," but "Internet Explorer isn't fully functional as it simply refused to load pages." From the report: The app is only 129MB in size and you can download it over at Github for both macOS and Windows. Once it's running it surprisingly only takes up around 200MB of RAM, even when running all of the old Windows 95 system utilities, apps, and games. If you run into any issues with the app you can always reset the Windows 95 instance inside the app and start over again. Enjoy this quirky trip down memory lane.
