Apple Developing Custom ARM-Based Mac Chip That Would Lessen Intel Role (bloomberg.com) 267

According to Bloomberg, Apple is designing a new chip for future Mac laptops that would take on more of the functionality currently handled by Intel processors. The chip is a variant of the T1 SoC Apple used in the latest MacBook Pro to power the keyboard's Touch Bar feature. The updated part, internally codenamed T310, is built using ARM technology and would reportedly handle some of the computer's low-power mode functionality. From the report: The development of a more advanced Apple-designed chipset for use within Mac laptops is another step in the company's long-term exploration of becoming independent of Intel for its Mac processors. Apple has used its own A-Series processors inside iPhones and iPads since 2010, and its chip business has become one of the Cupertino, California-based company's most critical long-term investments. Apple engineers are planning to offload the Mac's low-power mode, a feature marketed as "Power Nap," to the next-generation ARM-based chip. This function allows Mac laptops to retrieve e-mails, install software updates, and synchronize calendar appointments with the display shut and not in use. The feature currently uses little battery life while run on the Intel chip, but the move to ARM would conserve even more power, according to one of the people. The current ARM-based chip for Macs is independent from the computer's other components, focusing on the Touch Bar's functionality itself. The new version in development would go further by connecting to other parts of a Mac's system, including storage and wireless components, in order to take on the additional responsibilities. Given that a low-power mode already exists, Apple may choose to not highlight the advancement, much like it has not marketed the significance of its current Mac chip, one of the people said. Building its own chips allows Apple to more tightly integrate its hardware and software functions. It also, crucially, allows it more of a say in the cost of components for its devices. However, Apple has no near-term plans to completely abandon Intel chips for use in its laptops and desktops, the people said.

Researchers Unveil First Ever Blueprint To Construct a Large Scale Quantum Computer (phys.org) 94

haruchai quotes a report from Phys.Org: An international team, led by a scientist from the University of Sussex, have today unveiled the first practical blueprint for how to build a quantum computer, the most powerful computer on Earth. The work features a new invention permitting actual quantum bits to be transmitted between individual quantum computing modules in order to obtain a fully modular large-scale machine capable of reaching nearly arbitrary large computational processing powers. Prof Hensinger said: "The availability of a universal quantum computer may have a fundamental impact on society as a whole. Without doubt it is still challenging to build a large-scale machine, but now is the time to translate academic excellence into actual application building on the UK's strengths in this ground-breaking technology. I am very excited to work with industry and government to make this happen." The computer's possibilities for solving, explaining or developing could be endless. However, its size will be anything but small. The machine is expected to fill a large building, consisting of sophisticated vacuum apparatus featuring integrated quantum computing silicon microchips that hold individual charged atoms (ions) using electric fields. The plans for creating a universal quantum computer has been published in the journal Science Advances.

So a precisely tuned flicker-frequency (40Hz in mice) does great things for brain function and maintenance -- so what deleterious effects do things like CRT monitors, mains-powered fluro/LED lighting etc have on our brains -- given that they're operating "out of sync" with our gamma waves?

Could it be that the increase in dementia/Alzheimer's is related to our exposure to such off-frequency flickering on a very wide scale, thanks to modern technology?

'No Man's Sky' Releases Huge New 'Foundation' Update (thenextweb.com) 112

"No Man's Sky changed a great deal this morning, getting new modes and a ton of gameplay tweaks thanks to update 1.1, the largest one yet," reports Kotaku. Calling it "the first of many free updates," the game's developers introduced a new Minecraft-style Creative Mode which "allows players to explore the universe without limits, and build a huge base," plus a tougher Survival Mode, "creating a much more challenging endurance experience." The Next Web calls it "features that really should have been in the game from Day One." Now, when you stumble upon a desolate outpost, you can build your own base on it, which can be upgraded with new housing, hydroponics, research, and storage buildings. If all goes well, you'll start to attract alien settlers who bring their own skills to your new society. As your stockpiles of resources begin to swell, you'll want to schlep them across the galaxy to other bases and trade terminals. Which is where freighters come in... Oh, and did I mention you can now stack items five times per inventory slot, meaning you can carry more stuff? Handy. "The discussion around No Man's Sky since release has been intense and dramatic," Hello Games announced Friday, describing update 1.1 as "putting in place a foundation for things to come... the first small step in a longer journey." Hello Games founder Sean Murray tweeted "We're getting better as quickly as we can for the players who invested in us," adding "Thank you for sticking with us." At 2 a.m. this morning, he tweeted "If you could have lived our lives over the last months, you'd know how meaningful this is," adding "Here's the update..."

So they didn't correlate the IMU data with ranging radar or even barometric altitude information so as to avoid this?

I know weight and volume are at a premium on such craft but a barometric sensor (even one capable of operating in Mars's rarefied atmosphere, is the size of a thumbnail and weighs just a fraction of a gram.

Submission + - The IRS Just Declared War on Bitcoin Privacy (fee.org)

SonicSpike writes: The Internal Revenue Service has filed a “John Doe” summons seeking to require U.S. Bitcoin exchange Coinbase to turn over records about every transaction of every user from 2013 to 2015.

That demand is shocking in sweep, and it includes: “complete user profile, history of changes to user profile from account inception, complete user preferences, complete user security settings and history (including confirmed devices and account activity), complete user payment methods, and any other information related to the funding sources for the account/wallet/vault, regardless of date.” And every single transaction.

The demand is not limited to owners of large amounts of Bitcoin or to those who have transacted in large amounts. Everything about everyone.

Equally shocking is the weak foundation for making this demand. In a declaration submitted to the court, an IRS agent recounts having learned of tax evasion on the part of one Bitcoin user and two companies. On this basis, he and the IRS claim “a reasonable basis for believing” that all U.S. Coinbase users “may fail or may have failed to comply” with the internal revenue laws.

The IRS’s effort to strip away the privacy of all Coinbase users is more broad than the government’s effort in recent cases dealing with cell site location information. In the CSLI cases, the government has sought data about particular suspects, using a standard below the probable cause standard required by the Fourth Amendment (“specific and articulable facts showing that there are reasonable grounds to believe”).

Comment Why don't they... (Score 2) 60

Instead of storing a music track (or movie) as an MP3 or MP4 file on a single server, why not break it up into a bitstream in chunks of less than a byte and distribute it amongst a large number of servers. Each file on each server would then appear to be nothing but a random bitstream bearing no relation to the actual original work.

To access/download said movie/music, all you need is the right piece of software and the key which activates a function that downloads the bitstream fragments from the relevant servers and re-orders them into the original track.

This way, no server will have a copy of the copyright-infringing material that could be recognised as the offending work so surely could not be the subject of a copyright violation.

Since the servers would be useless without the key and the key would be useless without the servers -- neither part constitutes the copyrighted work.

Yeah, it's a form of distributed encryption -- but how do copyright holders issue a takedown notice for something that is clearly not their copyrighted content?

Just a thought. Probably already been done because there's nothing new in the universe.

If I was Mr Trump, I'd be gravely concerned that those who have most to lose from this victory might seek out a grassy knoll somewhere to "put things right". From what I read of history, it would not be "unprecedented" -- which would then leave the USA "unpresidented". People who aspire to power often don't take failure very well.

Too late!

Here in New Zealand Samsung did a huge recall of washing machines that were burning houses down. Apparently, when used with a full load, the machines would splash water on the electrics and the resulting current flow could precipitate a fire in which the plastic parts of the machine (top and cover) went up in flames -- setting fire to anything else that was nearby (such as your house).

Samsung delivered my replacement machine this week (after I had to wait a hell of a long time) and I asked them if I got a free Note 7 phone to go with it -- since it's Guy Fawkes this weekend and sometimes those bonfires are hard to get lit after a spring shower.

They said "no". Bugger!

Anyway, the new machine is so ugly we've called it Davros.

Comment The terrorists have won (Score 5, Insightful) 247

When your own government acts like terrorists -- you know the terrorists have won.

The terrorists have very effectively smashed the US Constitution and removed a huge swathe of "freedoms" that were previously enjoyed by Western nations. They did not do this alone -- the governments of those nations were complicit with the terrorists' objectives by bending to the pressure.

As Midnight OIl said: I'd rather die on my feet than live on my knees. Sadly, Western governments have opted to strip their peoples of the freedoms they're (allegedly) trying to protect, in promise of security.
