03/27/24English
Slashdot A British court has ruled that Julian Assange can't be extradited to the United States on espionage charges unless U.S. authorities guarantee he won't get the death penalty, giving the WikiLeaks founder a partial victory in his long legal battle over the site's publication of classified American documents. From a report: Two High Court judges said they would grant Assange a new appeal unless U.S. authorities give further assurances within three weeks about what will happen to him. The ruling means the legal saga, which has dragged on for more than a decade, will continue -- and Assange will remain inside London's high-security Belmarsh Prison, where he has spent the last five years. Judges Victoria Sharp and Jeremy Johnson said the U.S. must guarantee that Assange, who is Australian, "is afforded the same First Amendment protections as a United States citizen, and that the death penalty is not imposed."

03/16/24English
Slashdot "Engineers have sent a 'poke' to the Voyager 1 probe," reports CNN, "and received a potentially encouraging response..."

"A new signal recently received from the spacecraft suggests that the NASA mission team may be making progress in its quest to understand what Voyager 1 is experiencing..." [T]hey hope to fix a communication issue with the aging spacecraft that has persisted for five months. Launched in 1977, Voyager 1 and its twin, Voyager 2, are venturing through uncharted cosmic territory along the outer reaches of the solar system. While Voyager 1 has continued to relay a steady radio signal to its mission control team on Earth, that signal has not carried any usable data since November, which has pointed to an issue with one of the spacecraft's three onboard computers...

On March 3, the team noticed that activity from one part of the flight data system stood out from the rest of the garbled data. While the signal wasn't in the format the Voyager team is used to when the flight data system is functioning as expected, an engineer with NASA's Deep Space Network was able to decode it... The decoded signal included a readout of the entire flight data system's memory, according to an update NASA shared.

"The (flight data system) memory includes its code, or instructions for what to do, as well as variables, or values used in the code that can change based on commands or the spacecraft's status," according to a NASA blog post. "It also contains science or engineering data for downlink. The team will compare this readout to the one that came down before the issue arose and look for discrepancies in the code and the variables to potentially find the source of the ongoing issue."

"The source of the issue appears to be with one of three onboard computers, the flight data subsystem (FDS), which is responsible for packaging the science and engineering data before it's sent to Earth," according to NASA's statement.

CNN reminds readers that Voyager 1 "is currently the farthest spacecraft from Earth at about 15 billion miles (24 billion kilometers) away." Both Voyager 1 and Voyager 2 are now in interstellar space.

03/14/24English
Slashdot Scientists have discovered a giant volcano on Mars, as well as a possible sheet of buried glacier ice near the planet's equator. Phys.Org reports: Imaged repeatedly by orbiting spacecraft around Mars since Mariner 9 in 1971 -- but deeply eroded beyond easy recognition, the giant volcano had been hiding in plain sight for decades in one of Mars' most iconic regions, at the boundary between the heavily fractured maze-like Noctis Labyrinthus (Labyrinth of the Night) and the monumental canyons of Valles Marineris (Valleys of Mariner). Provisionally designated "Noctis volcano" pending an official name, the structure is centered at 7 degrees 35' S, 93 degrees 55' W. It reaches +9022 meters (29,600 feet) in elevation and spans 450 kilometers (280 miles) in width. The volcano's gigantic size and complex modification history indicate that it has been active for a very long time. In its southeastern part lies a thin, recent volcanic deposit beneath which glacier ice is likely still present. This combined giant volcano and possible glacier ice discovery is significant, as it points to an exciting new location to study Mars' geologic evolution through time, search for life, and explore with robots and humans in the future. The announcement was made at the 55th Lunar and Planetary Science Conference in The Woodlands, Texas. You can read more about it here (PDF).

03/11/24English
Slashdot In 1995 Scottish video game designer Chris Sawyer created the business simulator game Transport Tycoon Deluxe — and within four years, Wikipedia notes, work began on the first version of an open source version that's still being actively developed. "According to a study of the 61,154 open-source projects on SourceForge in the period between 1999 and 2005, OpenTTD ranked as the 8th most active open-source project to receive patches and contributions. In 2004, development moved to their own server."

Long-time Slashdot reader orudge says he's been involved for almost 25 years. "Exactly 21 years ago, I received an ICQ message (look it up, kids) out of the blue from a guy named Ludvig Strigeus (nicknamed Ludde)." "Hello, you probably don't know me, but I've been working on a project to clone Transport Tycoon Deluxe for a while," he said, more or less... Ludde made more progress with the project [written in C] over the coming year, and it looks like we even attempted some multiplayer games (not too reliable, especially over my dial-up connection at the time). Eventually, when he was happy with what he had created, he agreed to allow me to release the game as open source. Coincidentally, this happened exactly a year after I'd first spoken to him, on the 6th March 2004...

Things really got going after this, and a community started to form with enthusiastic developers fixing bugs, adding in new features, and smoothing off the rough edges. Ludde was, I think, a bit taken aback by how popular it proved, and even rejoined the development effort for a while. A read through the old changelogs reveals just how many features were added over a very short period of time. Quick wins like higher vehicle limits came in very quickly, and support for TTDPatch's NewGRF format started to be functional just four months later. Large maps, improved multiplayer, better pathfinders, improved TTDPatch compatibility, and of course, ports to a great many different operating systems, such as Mac OS X, BeOS, MorphOS and OS/2. It was a very exciting time to be a TTD fan!

Within six years, ambitious projects to create free replacements for the original TTD graphics, sounds and music sets were complete, and OpenTTD finally had its 1.0 release. And while we may not have the same frantic addition of new features we had in 2004, there have still been massive improvements to the code, with plenty of exciting new features over the years, with major releases every year since 2008. he move to GitHub in 2018 and the release of OpenTTD on Steam in 2021 have also re-energised development efforts, with thousands of people now enjoying playing the game regularly. And development shows no signs of slowing down, with the upcoming OpenTTD 14.0 release including over 40 new features!

"Personally, I would like to say thank you to everyone who has supported OpenTTD development over the past two decades..." they write, adding "Finally, of course, I'd like to thank you, the players! None of us would be here if people weren't still playing the game.

"Seeing how the first twenty years have gone, I can't wait to see what the next twenty years have in store. :)"

03/06/24English
Slashdot A washing-machine-sized satellite is to "name and shame" the worst methane polluters in the oil and gas industry. From a report: MethaneSat will provide the first near-comprehensive global view of leaks of the potent greenhouse gas from the oil and gas sector, and all of the data will be made public. It will provide high-resolution data over wider areas than existing satellites. Methane, also called natural gas, is responsible for 30% of the global heating driving the climate crisis. Leaks from the fossil fuel industry are a major source of human-caused emissions and stemming these is the fastest single way to curb temperature rises.

MethaneSat was developed by the Environmental Defense Fund, a US NGO, in partnership with the New Zealand Space Agency and cost $88m to build and launch. Earlier EDF measurements from planes show methane emissions were 60% higher than calculated estimates published by US authorities and elsewhere. More than 150 countries have signed a global methane pledge to cut their emissions of the gas by 30% from 2020 levels by 2030. Some oil and gas companies have made similar pledges, and new regulations to limit methane leaks are being worked on in the US, EU, Japan and South Korea.

The EDF's senior vice-president, Mark Brownstein, said: "MethaneSat is a tool for accountability . I'm sure many people think this could be used to name and shame companies who are poor emissions performers, and that's true. But [it] can [also] help document progress that leading companies are making in reducing their emissions." The oil and gas industry knows how to stop leaks and the cost of doing so is usually very modest, said Steven Hamburg, the EDF's chief scientist and MethaneSat project leader: "Some call it low hanging fruit. I like to call it fruit lying on the ground."

03/04/24English
Slashdot "Linux gained from 3% to 4% in 8 months," writes longtime Slashdot reader bobdevine. Linuxiac reports: According to the latest data from StatCounter, a leading web traffic analysis tool, Linux's market share has reached 4.03%. At first glance, the number might seem modest, but it represents a significant leap. Let's break it down. It took Linux 30 years to secure a 3% share of desktop operating systems, a milestone reached last June. Impressively, the open-source operating system has surged by an additional 1% in the last eight months.

02/26/24English
Slashdot Landscaping tech company Husqvarna has partnered with Bethesda to bring the original 1993 Doom to its $2,000+ robotic lawnmowers. Kotaku reports: This new way to play Doom arrives in April on all Nera robotic lawnmower models. You don't have to pay for the game, either, just a $2,000+ lawnmower. Instead, just download it and play the shooter via the robo-mower's built-in screen. To rotate your view, you turn the knob and to shoot demons, you press it down. You hold the start button to move forward.

A few caveats to mention. First, this isn't available in the United States. Why? I don't know. Perhaps we can't be trusted with video games on lawnmowers? Secondly, this isn't all of Doom. Instead, it's just the first episode -- Knee Deep In The Dead -- which is arguably its most famous one, sure, but just keep in mind you won't be able to play the rest of the beloved shooter in the middle of your backyard on a tiny LCD screen. Sorry.

Sadly, this won't be a permanent feature that you can show off to family and friends for years to come. Instead, Doom and all its demons and guns will be removed from lawnmowers on September 9. So enjoy it while you can.

02/23/24English
Slashdot Three top-tier X-class solar flares launched off the sun between Wednesday and Thursday. The first two occurred seven hours apart, coming in at X1.9 and X1.6 magnitude respectively. The third, the most powerful of the current 11-year "solar cycle," ranked an impressive X6.3. From a report: Solar flares, or bursts of radiation, are ranked on a scale that goes from A, B and C to M and X, in increasing order of intensity. They usually originate from sunspots, or bruiselike discolorations on the surface of the sun. Sunspots are most common near the height of the 11-year solar cycle. The current cycle, number 25, is expected to reach its peak this year. The more sunspots, the more opportunities for solar flares.

Solar flares and accompanying coronal mass ejections, or CMEs, can influence "space weather" across the solar system, and even here on Earth. CMEs are slower shock waves of magnetic energy from the sun. Flares can reach Earth in minutes, but CMEs usually take at least a day. All three of the X-class solar flares disrupted shortwave radio communications on Earth. But the first two flares did not release a CME; the verdict is still out regarding whether the third flare did. High-frequency radio waves propagate by bouncing off electrons in Earth's ionosphere. That's a layer of Earth's atmosphere between 50 and 600 miles above the ground.

When a solar flare occurs, that radiation travels toward Earth at the speed of light. It can ionize additional particles in the lower ionosphere. Radio waves sent from devices below it then impact that extra-ionized layer and lose energy, and aren't able to be bent by ions at the top of the ionosphere. That means signals can't travel very far, and radio blackouts are possible. Three back-to-back radio blackouts occurred in response to the trio of flares, but primarily over the Pacific and Indian oceans. They were rated "R3" or greater on a 1 through 5 scale. According to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center, that results in a "wide area blackout of [high frequency] radio communication, [and] loss of radio contact for about an hour on sunlit side of Earth." Low-frequency navigation signals, like those used on aircraft traveling overseas, can be degraded too.

02/18/24English
Slashdot The great libraries of the ancient classical world are "legendary... said to have contained stacks of texts," writes ScienceAlert. But from Rome to Constantinople, Athens to Alexandria, only one collection survived to the present day.

And here in 2024, "we can now start reading its contents." A worldwide competition to decipher the charred texts of the Villa of Papyri — an ancient Roman mansion destroyed by the eruption of Mount Vesuvius — has revealed a timeless infatuation with the pleasures of music, the color purple, and, of course, the zingy taste of capers. The so-called Vesuvius challenge was launched a few years ago by computer scientist Brent Seales at the University of Kentucky with support from Silicon Valley investors. The ongoing 'master plan' is to build on Seales' previous work and read all 1,800 or so charred papyri from the ancient Roman library, starting with scrolls labeled 1 to 4.

In 2023, the annual gold prize was awarded to a team of three students, who recovered four passages containing 140 characters — the longest extractions yet. The winners are Youssef Nader, Luke Farritor, and Julian Schilliger. "After 275 years, the ancient puzzle of the Herculaneum Papyri has been solved," reads the Vesuvius Challenge Scroll Prize website. "But the quest to uncover the secrets of the scrolls is just beginning...." Only now, with the advent of X-ray tomography and machine learning, can their inky words be pulled from the darkness of carbon.

A few months ago students deciphered a single word — "purple," according to the article. But "That winning code was then made available for all competitors to build upon." Within three months, passages in Latin and Greek were blooming from the blackness, almost as if by magic. The team with the most readable submission at the end of 2023 included both previous finders of the word 'purple'. Their unfurling of scroll 1 is truly impressive and includes more than 11 columns of text. Experts are now rushing to translate what has been found. So far, about 5 percent of the scroll has been unrolled and read to date. It is not a duplicate of past work, scholars of the Vesuvius Challenge say, but a "never-before-seen text from antiquity."

One line reads: "In the case of food, we do not right away believe things that are scarce to be absolutely more pleasant than those which are abundant."

Display this news only Asahi Linux Project's OpenGL Support On Apple Silicon Officially Surpasses Apple's
02/15/24English
Slashdot Andrew Cunningham reports via Ars Technica: For around three years now, the team of independent developers behind the Asahi Linux project has worked to support Linux on Apple Silicon Macs, despite Apple's total lack of involvement. Over the years, the project has gone from a "highly unstable experiment" to a "surprisingly functional and usable desktop operating system." Even Linus Torvalds has used it to run Linux on Apple's hardware. The team has been steadily improving its open source, standards-conformant GPU driver for the M1 and M2 since releasing them in December 2022, and today, the team crossed an important symbolic milestone: The Asahi driver's support for the OpenGL and OpenGL ES graphics have officially passed what Apple offers in macOS. The team's latest graphics driver fully conforms with OpenGL version 4.6 and OpenGL ES version 3.2, the most recent version of either API. Apple's support in macOS tops out at OpenGL 4.1, announced in July 2010.

Developer Alyssa Rosenzweig wrote a detailed blog post that announced the new driver, which had to pass "over 100,000 tests" to be deemed officially conformant. The team achieved this milestone despite the fact that Apple's GPUs don't support some features that would have made implementing these APIs more straightforward. "Regrettably, the M1 doesn't map well to any graphics standard newer than OpenGL ES 3.1," writes Rosenzweig. "While Vulkan makes some of these features optional, the missing features are required to layer DirectX and OpenGL on top. No existing solution on M1 gets past the OpenGL 4.1 feature set... Without hardware support, new features need new tricks. Geometry shaders, tessellation, and transform feedback become compute shaders. Cull distance becomes a transformed interpolated value. Clip control becomes a vertex shader epilogue. The list goes on."

Now that the Asahi GPU driver supports the latest OpenGL and OpenGL ES standards -- released in 2017 and 2015, respectively -- the work turns to supporting the low-overhead Vulkan API on Apple's hardware. Vulkan support in macOS is limited to translation layers like MoltenVK, which translates Vulkan API calls to Metal ones that the hardware and OS can understand. [...] Rosenzweig's blog post didn't give any specific updates on Vulkan except to say that the team was "well on the road" to supporting it. In addition to supporting native Linux apps, supporting more graphics APIs in Asahi will allow the operating system to take better advantage of software like Valve's Proton, which already has a few games written for x86-based Windows PCs running on Arm-based Apple hardware.
