Hello, I've been enjoying Paperspace instances (A4000 these days) for a while. However, since a week, I had catastrophic storage performances. I suspect they started virtualizing Windows (since they announced dropping support for new users).

Can someone suggest an alternative?

Here are my criterias:

• support for Windows templates
• no upfront cost (210€ upfront on Akamai, 100€ for OVH, seriously for 0.8$/h instances!)
• available in EU
• GPU models appropriate for gaming
• affordable prices, I'm currently paying 0.8$/h + 11$ for monthly storage (500GB SSD + one snapshot)

Commonwealth Fusion has published five peer-reviewed papers laying out the physics case for ARC, its planned 400 MW fusion power plant, which would follow the company's smaller SPARC tokamak now under construction. The papers suggest ARC could produce more energy than it consumes using high-temperature superconducting magnets, molten-salt heat extraction, and 15-minute fusion pulses. Ars Technica reports:

ARC will be a tokamak that hosts fusion between hydrogen's two heavier isotopes, deuterium and tritium. This reaction results in a helium nucleus and releases a neutron and radiation. The helium transfers heat to the plasma, maintaining the conditions needed for fusion, but it is otherwise a waste product, referred to as "ash" in the fusion context. The neutron and radiation, however, are put to use. Part of that use is simply imparting energy into a blanket of molten salt that surrounds the fusion chamber. That energy, in the form of heat, will be used to drive a turbine that produces the electricity. The molten salt includes lithium ions; when one lithium isotope absorbs a neutron, it decays into more helium, plus tritium that can be used as fuel for the reactor. There are isotopes present that will also release additional neutrons, allowing this process to generate sufficient fuel.

Overall, the present design of ARC is expected to produce about 1.13 GW of fusion power, with 500 MW of that extracted as electricity. Some of that (100 MW) will be needed to power the plant's operations, leaving 400 MW to be sent to the grid. The rest of the energy is either kept in the tokamak to maintain the fusion reactions or lost due to inefficiencies in the heat and energy transfer of the system. There's a lot of uncertainty about these numbers; the 1.13 GW is just the center of a range of potential values running from 900 MW to 1.3 GW, so the 400 MW output may need to be adjusted up or down accordingly.

Some of that 400 MW comes during periods where fusion is not occurring. The nuclear reactions will occur within 15-minute-long periods that will be interspersed with one minute resets. The resets are meant to be kept short enough that nothing has much of a chance to cool down before it gets heated up again -- thermal inertia will let it continue generating power. That will be one of the key differentiators with SPARC, which doesn't have the heat extraction needed to maintain stable fusion for these long time periods, and so can't maintain the near constant temperatures needed for reliable power generation.

It's inevitable that parts of the device will be exposed to radiation and perhaps fusion plasma. The inner walls of the reactor will be shielded by tungsten, which will limit erosion by the conditions. Meanwhile, the vacuum vessel is designed to be replaced every one to two years. The papers note that this flexibility will allow them to make some design changes even after ARC is built. To enable this, the whole tokamak is meant to split in half for maintenance.

After nearly 20 years on the platform, The Electronic Frontier Foundation (EFF) says it is leaving X. "This isn't a decision we made lightly, but it might be overdue," the digital rights group said. "The math hasn't worked out for a while now." From the report:

We posted to Twitter (now known as X) five to ten times a day in 2018. Those tweets garnered somewhere between 50 and 100 million impressions per month. By 2024, our 2,500 X posts generated around 2 million impressions each month. Last year, our 1,500 posts earned roughly 13 million impressions for the entire year. To put it bluntly, an X post today receives less than 3% of the views a single tweet delivered seven years ago. [...]

When you go online, your rights should go with you. X is no longer where the fight is happening. The platform Musk took over was imperfect but impactful. What exists today is something else: diminished, and increasingly de minimis.

EFF takes on big fights, and we win. We do that by putting our time, skills, and our members' support where they will effect the most change. Right now, that means Bluesky, Mastodon, LinkedIn, Instagram, TikTok, Facebook, YouTube, and eff.org. We hope you follow us there and keep supporting the work we do. Our work protecting digital rights is needed more than ever before, and we're here to help you take back control.

The UK's science minister is announcing details of a five-year, £2.5 billion investment in nuclear fusion, reports the Times of London, "including building one of the world's first prototype fusion power plants in Nottinghamshire and developing a UK sector projected to employ 10,000 people by 2030."

Despite the potentially transformative impact of fusion, which in theory could provide limitless clean energy and create a £12 trillion global market, no country has managed to use this fledgling technology to generate useable electricity... [T]he UK is backing a spherical tokamak design... investing an initial £1.3 billion into a prototype fusion power plant called Step (Spherical Tokamak for Energy Production) on the site of a decommissioned coal-fired power station at West Burton in Nottinghamshire. Paul Methven, chief executive of the government-owned UK Industrial Fusion Solutions, which is delivering the Step project, said the aim is to get the reactor operating early in the 2040s. "It's quite an aggressive programme," he said. "We need to show that we can achieve genuine 'wall socket' energy — which has not been done before."

On Monday, [science minister] Vallance will also announce £180 million for a facility in Culham, Oxfordshire, to manufacture tritium fuel and £50 million for training 2,000 scientists and engineers in fusion-related disciplines. The government is also buying a £45 million fusion-dedicated AI supercomputer called Sunrise to model plasma physics. Scientists at the UK Atomic Energy Authority last year developed an AI model that can rapidly simulate how the ultra-hot fuel in a fusion power plant will behave, cutting calculations that previously took days down to seconds...

Vallance will also announce new support and collaboration for the many fusion, robotics, engineering and AI start-ups working in Britain, to develop a strong supply chain for a new fusion sector. One of those companies, Tokamak Energy, which spun out from the UK Atomic Energy Authority in 2009, has already built a smaller reactor that has informed the Step design. In March 2022, it became the first private organisation in the world to surpass 100 million degrees Celsius in its reactor.

President Donald Trump has pardoned the Founder of Binance, Changpeng Zhao, who pleaded guilty to anti-money-laundering violations and served prison time. The Associated Press reports:

Zhao has deep ties to World Liberty Financial, a crypto venture that the Republican president and his sons Eric and Donald Jr. launched in September. Trump's most recent financial disclosure report reveals he made more than $57 million last year from World Liberty Financial, which has launched USD1, a stablecoin pegged at a 1-to-1 ratio to the U.S. dollar. World Liberty Financial also recently announced that an investment fund in the United Arab Emirates would be using $2 billion worth of USD1 to purchase a stake in Binance. Zhao also has publicly said that he had asked Trump for a pardon that could nullify his conviction.

White House press secretary Karoline Leavitt said in a statement Thursday that the Biden administration prosecuted Zhao out of a "desire to punish the cryptocurrency industry." She said there were "no allegations of fraud or identifiable victims," though Zhao had pleaded guilty in November to one count of failing to maintain an anti-money-laundering program.

German IT news outlet Heise reports [German-language article] that the northern most state Schleswig-Holstein has, after half a year of frantic data migration work, successfully migrated their MS Outlook mail and groupware setups to a FOSS solution using Open-Xchange and Thunderbird.

Stakeholders consider the move a major success and milestone to digital sovereignty and saving costs. This move makes the state a pioneer in Germany. As a next major step Schleswig-Holstein plans to migrate their authorities and administrations desktop PCs to Linux.

The state has achieved "digital sovereignty by ditching Microsoft for open source solutions". European nations "have generally been more progressive in adopting open source solutions for government operations."

The migration affected around 30,000 employees across various government departments. This includes the State Chancellery, ministries, judiciary, state police, and other state authorities. Over 40,000 mailboxes containing more than 100 million emails and calendar entries were moved to the new system. The state has adopted Open-Xchange as its email server solution and Thunderbird as the email client...

[Digitization Minister Dirk Schrödter] emphasized that "We are real pioneers. We can't fall back on the experience of others -, there is hardly a comparable project of this magnitude anywhere in the world."

Bitcoin and Ethereum both saw record liquidations as investors reacted to fears over a trade war, which saw many crypto investors move their money to stablecoins or safer assets... Bitcoin fell by more than 10 per cent to below $110,000, before recovering to $113,096 on Saturday morning. The value of Ethereum slumped by 11.2 per cent to $3,878. Other cryptocurrencies, including XRP, Doge and Ada, fell around 19 per cent, 27 per cent, and 25 per cent in the last 24 hours, respectively.

Bloomberg reports some statistics:

Citing 24-hour data from Coinglass, the report noted that more than $19 billion has been wiped out in the "largest liquidation event in crypto history", which impacted more than 1.6 million traders. It added that more than $7 billion of those positions were sold in less than one hour of trading on October 10. According to data on CoinMarketCap, the cryptocurrency market cap has dived to $3.74 trillion from the record-high $4.30 trillion level, the previous day. Trading volumes as of the market close were recorded at $490.23 billion.

Bitcoin retreated on Friday, as US-China trade tensions reignited, after racing to record highs earlier in the week as persistent rate-cut bets and signs of some cooling in geopolitical tensions helped boost risk. Bitcoin was trading at $105,505.4 on Friday, down 13.15% on the day.

"California's biggest electric utilities pulled off a record-breaking test..." reports Semafor, "during the 7pm-9pm window that is typically its time of peak demand as people come home from work."

Pacific Gas & Electric and other top California power companies switched on residential batteries in more than 100,000 homes and drew power from them into the broader statewide grid. The purpose of the test — the largest ever in the state, which has by far the most home battery capacity in the U.S. — was to see just how much power is really there for the utility to tap, and to ensure it could be switched on, effectively running the grid in reverse, without causing a crash.

The result, which the research firm Brattle published this week, was 535 megawatts, equal to adding a big hydro dam or a half-sized nuclear reactor at a fraction of the cost. "Four years ago this capacity didn't even exist," Kendrick Li, PG&E's director of clean energy programs, told Semafor. "Now it's a really attractive option for us. It would be silly not to harness what our customers have installed...." Last week's test proved that in times of peak demand, PG&E can lean on its customers' batteries rather than turn on a gas-fired peaker plant or risk a blackout, Li said.

Virtual power plants (VPPs) also facilitate the addition of more solar energy on the grid: At the moment, California has so much solar generation at peak hours that it can push the wholesale power price close to or even below zero, a headache for grid managers and a disincentive for renewable project developers. The careful manipulation of networked residential batteries smooths out the timing disparity between peak sunshine at midday and peak demand in the evening, allowing the excess to be soaked up and redeployed when it's actually needed, and making power cheaper for everyone. The expanded use of VPPs shouldn't be noticeable to battery owners, Li said, except for the money back on their power bill; nothing about the process prevents them from running their AC or dishwasher while their battery is being tapped. The network can also run in reverse, with the utility taking excess power from the grid at times of low demand and sending it into home batteries for storage.

California could easily reach over a gigawatt of VPP capacity within five years, Li said. Nationwide, a Department of Energy study during the Biden administration forecast that VPP capacity could reach up to 160 gigawatts by 2030, essentially negating the need for dozens of new fossil fuel power plants, with no emissions and at a far lower cost. In 2024, utilities in 34 states moved to initiate or expand VPP networks, according to the advocacy group VP3.

Even with a reduction in federal credits, virtual power plants "offer a way for residential solar-plus-storage systems to remain economically attractive for homeowners — who get paid for the withdrawn power," the article points out — and "a way to make better use of clean energy resources that have already been built."

Sunrun's distributed battery fleet "delivered more than two-thirds of the energy," notes Electrek, "In total, the event pumped an average of 535 megawatts (MW) onto the grid — enough to power over half of San Francisco... This isn't a one-off. Sunrun's fleet already helped drop peak demand earlier this summer, delivering 325 MW during a similar event on June 24.

"The company compensates customers up to $150 per battery per season for participating."

A Manhattan jury convicted Tornado Cash co-founder Roman Storm on Wednesday of conspiring to operate an unlicensed money-transfer business, though jurors deadlocked on charges of money laundering conspiracy and sanctions violations after three days of deliberation.

Federal prosecutors alleged Storm helped cybercriminals launder more than $1 billion through the cryptocurrency mixing platform, which launched in 2019 as a decentralized protocol designed to obscure transaction origins by pooling and redistributing funds through smart contracts.

Heise, a German IT news publisher, reports that the German state of Brandenburg is getting the world's tallest wind turbine, with an overall height of 300 meters (approximately 365 meters including rotor blades), designed to capture so-called third-level winds at higher altitudes. The article also includes a short 3D animation illustrating the construction and its size relative to standard modern wind turbines.

The wind turbine uses a dual-framework base instead of a traditional closed tower to access stronger high-altitude winds, aiming to match offshore energy output while keeping onshore operating costs.

According to Heise, the prototype could lead to the installation of up to 1,000 units across Germany -- fitting seamlessly between existing wind farms without needing extra land.

U.S. prosecutors and the Commodity Futures Trading Commission (CFTC) have officially closed their investigations into Polymarket, the decentralized, blockchain-powered prediction market platform where users bet with real cryptocurrency on the outcomes of future events.

The DOJ was investigating Polymarket last year, reportedly for allowing U.S. users to place bets on the site despite Polymarket being required to block U.S. traders

The FBI raided Polymarket CEO Shayne Coplan's Manhattan apartment last November, seizing his phone and electronic devices. A source close to the matter told The New York Post it was politically motivated due to Polymarket's successful prediction of Trump's election win. It's "grand political theater at its worst," the source said. "They could have asked his lawyer for any of these things. Instead, they staged a so-called raid so they can leak it to the media and use it for obvious political reasons."

In March an executive order directed America's treasury secretary to create two stockpiles of crypto assets (to accompany already-existing "strategic reserves" of gold and foreign currencies). And the Washington Post notes these new stockpiles would include "cryptocurrency seized by federal agencies in criminal or civil proceedings." But how big would America's "Strategic Bitcoin Reserve" be — and what other cryptocurrencies would the U.S. government hold in its "Digital Asset Stockpile"?

"New data on what crypto cash the U.S. government has seized may now provide some answers.

It suggests the crypto reserves will together hold more than $21 billion in cryptocurrency... The stockpile will be funded with whatever crypto assets the Treasury holds other than bitcoin, leaving the stockpile's composition to be largely determined by a mixture of chance and criminal conduct. That unconventional method for selecting government financial holdings had the benefit of making the reserves cost-neutral for the taxpayer.

It also provided a way to estimate what exactly might go into the two pools before results are released from an official accounting of U.S. crypto holdings that is underway.Because government seizures are disclosed in court documents, news releases and other sources, crypto-tracking firms can use those notices to monitor which digital assets the U.S. government holds. Chainalysis, a blockchain analytics firm, reviewed cryptocurrency wallets that appear to be associated with the U.S. government for The Washington Post. The company estimated how much bitcoin it holds, and the other crypto tokens in its top 20 digital holdings as of May 13, by tracking transactions involving those wallets.

The United States' top 20 crypto holdings according to Chainalysis are worth about $20.9 billion as of 3 p.m. Eastern on May 28, with $20.4 billion in bitcoin and about $493 million in other digital assets. It has been scooped up from crimes such as stolen funds, scams and sales on dark net markets. Those estimates put the U.S. government's top crypto holdings at less than the approximately $25 billion worth of oil held in the U.S. Strategic Petroleum Reserve. Their value is nearly double the Fed's listing for U.S. gold holdings, although that figure uses outdated pricing and would be over $850 billion at current prices...

The crypto tokens headed for the U.S. Digital Asset Stockpile according to the Chainalysis list include ethereum, the world's second-largest digital asset, and a string of other crypto tokens with punier name recognition. They include derivatives of bitcoin and ethereum that mirror those cryptocurrencies' prices, several stable coins designed to be pegged in value to the U.S. dollar, and 10 tokens tied to specific companies, including the cryptocurrency exchanges FTX, which imploded in 2022 after defrauding customers, and Binance.

Two U.S. states have already passed legislation creating their own cryptocurrency reserve funds, the article points out. But ethereum co-founder Vitalik Buterin complained to the Post in March that crypto's "original spirit...is about counterbalancing power" — including government and corporate power, and getting too close to "one particular government team" could conflict with its mission of decentralization and openness. And he's not the only one concerned:

Austin Campbell, a professor at New York University's business school and a principal at crypto advisory firm Zero Knowledge, sees hypocrisy in crypto enthusiasts cheering the government's strategic reserves. The bitcoin community in particular "has historically been about freedom from sovereign interference," he said.

A German nuclear fusion startup called Proxima Fusion has unveiled its "Stellaris" fusion power plant designed to operate reliably and continuously without the instabilities of tokamaks. It's backed by $65 million in funding, with plans to build a fully operational fusion reactor by 2031. TechCrunch reports:

Tokamaks and stellarators are types of fusion reactors that use electromagnets to contain fusion plasma. Tokamaks rely on external magnets and an induced plasma current but are known for instability. Stellarators, by contrast, use only external magnets, which, in theory, enable better stability and continuous operation. However, according to Dr. Francesco Sciortino, co-founder and CEO of Proxima Fusion, Proxima's "Stellaris" design is the first peer-reviewed fusion power plant concept that demonstrates it can operate reliably and continuously, without the instabilities and disruptions seen in tokamaks and other approaches.

Proxima published its findings in Fusion Engineering and Design, choosing to share this information publicly to support open-source science. "Our American friends can see it. Our Chinese friends can see it. Our claim is that we can execute on this faster than anyone else, and we do that by creating a framework for integrated physics, engineering, and economics. So we're not a science project anymore," Sciortino told TechCrunch over a call. "We started out as a group of founders saying it's going to take us two years to get to the Stellaris design ... We actually finished after one year. So we've accelerated by a year," he added.

The US Department of Justice (DOJ) has been authorized to sell approximately 69,370 Bitcoin seized in connection with the Silk Road darknet marketplace, a haul currently valued at around $6.5 billion, DB News reported Wednesday. The decision is set to end a years-long legal dispute over the BTC stash's ownership. On December 30, a federal judge ruled in favor of the DOJ's request to liquidate the crypto assets, the report said. Battle Born Investments, which had asserted a claim to the Bitcoin stash through a bankruptcy estate, ultimately failed in its bid to delay the sale.

As noted, the group had pursued a Freedom of Information Act (FOIA) request seeking the identity of "Individual X," who initially surrendered Bitcoin, but the effort also proved unsuccessful. Battle Born's legal counsel criticized the DOJ's handling of the case, alleging the department employed "procedural trickery" in its use of civil asset forfeiture to avoid scrutiny. The DOJ, in its arguments before the court, cited Bitcoin's price volatility as motivation for seeking a quick sale of the seized assets. A DOJ spokesperson, when contacted, stated, "The Government will proceed further consistent with the judgment in this case."

The update comes after the US Supreme Court refused to hear an appeal challenging the seizure of the Bitcoin stash, which was brought by Battle Born last October. The decision likely paved the way for the US government to sell Bitcoin, which was valued at $4.4 billion at the time. The US Marshals Service is expected to manage the liquidation process, which, if confirmed, will be one of the largest sales of seized crypto in history.
