The Raspberry Pi Foundation has doubled the maximum amount of RAM available in the Raspberry Pi 4 to 8GB with a new device it's selling for $75. An anonymous reader writes: To take advantage of the RAM increase, the foundation is also releasing a new 64-bit version of its operating system in early beta. The new Raspberry Pi 4 is otherwise identical to the device that was announced in June last year, meaning it has the same ARM-based CPU, and HDMI, USB 3, and Ethernet ports. 8GB is a lot of RAM considering the Raspberry Pi's size and price. It's the same as many flagship smartphones released this year, and enough for an entry-level gaming PC. The Raspberry Pi Foundation says the additional memory should be useful for compiling large pieces of software, running heavy server workloads, or maybe just having more browser tabs open at once. We're sure that it won't take long for the community to come up with many interesting uses.

Sweden's death rate per million (376) "is far in advance of Norway's (44), Denmark's (96) and Finland's (55) — countries with similar welfare systems and demographics, but which imposed strict lockdowns..." reports the Guardian, "raising concerns that the country's light-touch approach to the coronavirus may not be helping it build up broad immunity."

"According to the scientific online publication Ourworldindata.com, Covid-19 deaths in Sweden were the highest in Europe per capita in a rolling seven-day average between 12 and 19 May. The country's 6.25 deaths per million inhabitants a day was just above the UK's 5.75."

Slashdot reader AleRunner writes: Immunity levels in Sweden, which were expected to reach 33% by the start of May have been measured at only 7.3%, suggesting that Sweden's lighter lockdown may continue indefinitely whilst other countries begin to revive their economies. Writing about new Swedish antibody results in the Guardian Jon Henley goes on to report that other European countries like Finland are already considering blocking travel from Sweden which may increase Sweden's long term isolation.

We have discussed before whether Sweden, which locked down earlier than most but with fewer restrictions could be a model for other countries.

As it is, now, the country is looking more like a warning to the rest of the world.

The Guardian concludes that the Swedish government's decision to avoid a strict lockdown "is thought unlikely to spare the Swedish economy. Although retail and entertainment spending has not collapsed quite as dramatically as elsewhere, analysts say the country will probably not reap any long-term economic benefit."

New submitter jsicolo shares a report: Nvidia Chief Scientist Bill Dally has released an open-source ventilator hardware design he developed in order to address the shortage resulting from the global coronavirus pandemic. The mechanical ventilator design developed by Dally can be assembled quickly, using off-the-shelf parts with a total cost of around $400 -- making it an accessible and affordable alternative to traditional, dedicated ventilators, which can cost $20,000 or more. The design created by Dally strives for simplicity, and basically includes just two central components -- a solenoid valve and a microcontroller. The design is called the OP-Vent, and in this video you can see how bare-bones it is in terms of hardware compared to existing alternatives, including some of the other more complex emergency-use ventilator designs developed in response to COVID-19.

The Raspberry Pi can be used for all sorts of maker projects, and the foundation has offered camera modules for it since 2013, adding vision-related functionality. The first module was a modest 5-megapixel affair that was eventually replaced by an 8-megapixel Sony sensor four years ago. Today, sees the arrival of a new much higher 12.3 megapixel quality camera, and a range of interchangeable lenses. From a report: The new camera is compatible with all Raspberry Pi models -- from Pi 1 Model B onwards -- with the exception of early Pi Zero boards. The camera is available to buy from today for $50.

The world's biggest PC company (in terms of shipments) now offers select models with Linux pre-installed. In doing so, it joins the existing club that includes Dell and other smaller players like Purism, ZaReason, and System76. From a report: If Linux has a special place in your heart, you will want to know Lenovo is partnering with the Fedora Project to give you your dream machine in the form of ThinkPad laptops that make it easy even for a newcomer to get started with Fedora. This is supposed to be a pilot program dubbed Linux Community Series -- Fedora Edition, which will include the ThinkPad P1 Gen2, ThinkPad X1 Gen8, ThinkPad P53, with the possibility that the company will expand the selection in the near future if it sees enough demand. These models will come with the newly released Fedora 32 Workstation Linux pre-installed, and will presumably be certified to play nice with it while only using first party repositories. That means the ThinkPad P53 and ThinkPad P1 Gen2 won't come with Nvidia drivers installed by default. However, that's easy to fix by downloading them from proprietary sources.
