Submission + - Tesla retreats from next-generation 'gigacasting' manufacturing process (reuters.com)

Submitted by theweatherelectric
theweatherelectric writes: Norihiko Shirouzu and Giulio Piovaccari for Reuters write, "Tesla has backed away from an ambitious plan for innovations in gigacasting, its pioneering manufacturing process, according to two sources familiar with the matter, in another sign that the electric-vehicle maker is retrenching amid falling sales and rising competition. Tesla has been a leader in gigacasting, a cutting-edge technique that uses huge presses with thousands of tons of clamping pressure to die-cast large sections of the car’s underbody. On a typical vehicle, the underbody can consist of hundreds of individual parts.

"Last year, as Tesla developed a new small-vehicle platform, it aimed to punch out the underbody in a single piece. But Tesla has since halted the effort, opting to stick with its more proven method of casting vehicle underbodies in three pieces: two gigacasted front and rear sections and a midsection made of aluminum and steel frames to store batteries, according to the two sources familiar with the matter."

Submission + - China Launches World's Largest Electric Container Ship (techtimes.com)

Submitted by AmiMoJo
AmiMoJo writes: China has reached a major landmark in green transportation with the launch of the world's largest fully electric container ship. Developed and manufactured by China Ocean Shipping Group (Cosco), the vessel is now operating a regular service route between Shanghai and Nanjing, aiming to reduce emissions significantly along its journey.

The Greenwater 01, an all-electric container ship, is positioning itself to be a shipping industry pioneer. Equipped with a main battery exceeding 50,000 kilowatt-hours, the vessel can accommodate additional battery boxes for longer voyages. These battery boxes, each containing 1,600 kilowatt-hours of electricity and similar in size to standard 20-foot containers, provide flexibility in extending the ship's travel range. With 24 battery boxes onboard, the Greenwater 01 can complete a journey consuming 80,000 kilowatt-hours of electricity. This is equivalent to saving 15 tonnes of fuel compared to a standard container ship, highlighting the efficiency of electric propulsion systems.

Submission + - Systemd wants to expand to include a sudo replacement (fosspost.org)

Submitted by Anonymous Coward
An anonymous reader writes: Systemd lead developer Lennart Poettering has posted on Mastodon about their upcoming v256 release of Systemd, which is expected to include a sudo replacement called “run0”.

The developer talks about the weaknesses of sudo, and how it has a large possible attack surface. For example, sudo supports network access, LDAP configurations, other types of plugins, and much more. But most importantly, its SUID binary provides a large attack service according to Lennart:

"I personally think that the biggest problem with sudo is the fact it’s a SUID binary though – the big attack surface, the plugins, network access and so on that come after it it just make the key problem worse, but are not in themselves the main issue with sudo. SUID processes are weird concepts: they are invoked by unprivileged code and inherit the execution context intended for and controlled by unprivileged code. By execution context I mean the myriad of properties that a process has on Linux these days, from environment variables, process scheduling properties, cgroup assignments, security contexts, file descriptors passed, and so on and so on."

He’s saying that sudo is a Unix concept from many decades ago, and a better privilege escalation system should be in place for 2024 security standards:

  "So, in my ideal world, we’d have an OS entirely without SUID. Let’s throw out the concept of SUID on the dump of UNIX’ bad ideas. An execution context for privileged code that is half under the control of unprivileged code and that needs careful manual clean-up is just not how security engineering should be done in 2024 anymore."

Submission + - Plato's final hours recounted in scroll found in Vesuvius ash (theguardian.com)

Submitted by Anonymous Coward
An anonymous reader writes: Newly deciphered passages from a papyrus scroll that was buried beneath layers of volcanic ash after the AD79 eruption of Mount Vesuvius may have shed light on the final hours of Plato, a key figure in the history of western philosophy.

In a groundbreaking discovery, the ancient scroll was found to contain a previously unknown narrative detailing how the Greek philosopher spent his last evening, describing how he listened to music played on a flute by a Thracian slave girl.

Despite battling a fever and being on the brink of death, Plato – who was known as a disciple of Socrates and a mentor to Aristotle, and who died in Athens around 348BC – retained enough lucidity to critique the musician for her lack of rhythm, the account suggests.

The decoded words also suggest Plato’s burial site was in his designated garden in the Academy of Athens, the world’s first university, which he founded, adjacent to the Mouseion. Previously, it was only known in general terms that he was buried within the academy.

The text also reveals that Plato was sold into slavery on the island of Aegina, possibly as early as 404BC when the Spartans conquered the island, or alternatively in 399BC, shortly after Socrates’ passing.

“Until now it was believed that Plato was sold into slavery in 387BC during his sojourn in Sicily at the court of Dionysius I of Syracuse,” Ranocchia said. “For the first time, we have been able to read sequences of hidden letters from the papyri that were enfolded within multiple layers, stuck to each other over the centuries, through an unrolling process using a mechanical technique that disrupted whole fragments of text.”

Ranocchia said the ability to identify these layers and virtually realign them to their original positions to restore textual continuity represented a significant advance in terms of gathering vast amounts of information.

Submission + - Russia arrests former world chess champion Garry Kasparov (mirror.co.uk)

Submitted by ArchieBunker
ArchieBunker writes: Russia has arrested Garry Kasparov and charged him in connection with foreign agent and terrorist charges — much to the former chess champion's amusement.

The city court in Syktyvkar, the largest city in Russia's northwestern Komi region, announced it had arrested the grandmaster in absentia alongside former Russian parliament member Gennady Gudkov, Ivan Tyutrin co-founder of the Free Russia Forum — which has been designated as an 'undesirable organisation in the country — as well as former environmental activist Yevgenia Chirikova.

All were charged with setting up a terrorist society, according to the court's press service. As all were charged in their absence, none were physically held in custody.

"The court has selected a measure of restraint for Garry Kasparov, Gennady Gudkov, Yevgenia Chirikova and Ivan Tyutrin, charged with establishing and heading a terrorist society, funding terrorist activity and justifying it publicly," the court said according to Kremlin-backed outlet TASS. "The court granted the investigative bodies’ motions to remand Kasparov, Gudkov, Chirikova and Tyutrin in custody as a measure of restraint."

Kasparov responded to the court's bizarre arrest statement in an April 24 post shared on X, formerly Twitter. "In absentia is definitely the best way I've ever been arrested," he said. "Good company, as well. I'm sure we're all equally honoured that Putin's terror state is spending time on this that would otherwise go persecuting and murdering."

Submission + - GM faces 2nd lawsuit over driver data collection without consent (freep.com)

Submitted by sinij
sinij writes:

One week after General Motors said it would stop collecting and sharing driver data, it faces a second lawsuit over collecting that information without drivers' consent and sharing it with third parties, which subsequently led to auto insurers justifying rate hikes. The complaint accuses GM and its connected-services subsidiary OnStar of invasion of privacy and deceptive and unfair practices.

Unfortunately, nobody at GM will go to jail over this.

Submission + - The Decomposition of Rotten Tomatoes

Mirnotoriety writes: The Decomposition of Rotten Tomatoes The most overrated metric in movies is erratic, reductive, and easily hacked — and yet has Hollywood in its grip.

“The studios didn’t invent Rotten Tomatoes, and most of them don’t like it,” says the filmmaker Paul Schrader. “But the system is broken. Audiences are dumber. Normal people don’t go through reviews like they used to. Rotten Tomatoes is something the studios can game. So they do.”

There is no shortage of humans and death always adjusts populations to suit resources so inconvenience for a few is not reason to breed.

Inflicting life means inflicting every last bit of suffering life entails. Life is homeopathically joyous on a good day and pretending otherwise is a lie. All we build falls, all we love dies, our strength becomes physical weakness and our mental acuity dulls then evaporates with age unless one dies early.

No amount of emotionalist instinctual denialism changes the above. To breed is to put innocents into a very bad world. That is not an accomplishment.

Even if you produce then nurture an intelligent, competent human that human shares a world with the yowling beastmob prone to eating those who speak truth to their preferred power or defy or are merely in the way of their superstition.

I refuse to be that cruel.

Submission + - NASA discovered a planet with a gas that is 'only produced (unilad.com) 1

Submitted by Baron_Yam
Baron_Yam writes: NASA explains: "The abundance of methane and carbon dioxide, and shortage of ammonia, support the hypothesis that there may be a water ocean underneath a hydrogen-rich atmosphere in K2-18 b.

"These initial Webb observations also provided a possible detection of a molecule called dimethyl sulfide (DMS). On Earth, this is only produced by life. The bulk of the DMS in Earth’s atmosphere is emitted from phytoplankton in marine environments."
