Researchers find that one person likely drove Bitcoin from $150 to $1,000

The bottom line is simple: if Bitcoin wants to be taken seriously it probably shouldn’t be this easy or legal to manipulate the markets. While decentralization is supposed to replace regulation it’s clear that there is still a way to go before it can be truly taken seriously.

Meltdown and Spectre: clearing up the confusion

For a typical user, the browser presents the highest risk, but we have yet to see proof of concept code that exploits this vulnerability through JavaScript – and browser vendors have started issuing patches as well (for example, Mozilla has issued a new version of Firefox, 57.0.4, where they have decreased the precision of time sources to make attacks such as Spectre more difficult or impossible). If you run stuff as Administrator: Spectre makes no difference for you really.

In other words: the world will end over the weekend.

From:  Microsoft Halts Bitcoin Transactions Because It’s An “Unstable Currency

While Bitcoin price has always fluctuated, it never swung like it did in the past three months. To be widely adopted by the financial sector, a digital or fiat currency must be stable in order to be useful, something that Bitcoin is definitely not.

The Search for Aliens Starts Now—in Antarctica

Like many subsea drones, the 10-foot-long Icefin is shaped like a torpedo. It made headlines in 2014 as one of the prototype drones that plumbed the Antarctic as part of a NASA program to test the technology. Now, a new program called the Ross Ice Shelf and Europa Underwater Probe (RISE UP), NASA is funding three expeditions to put an upgraded Icefin under the ice. This was its first deployment..

When Icefin dove to the sea floor it found odd, feathery creatures waiting for them. “My favorite moments from the seafloor were our visits by crinoids…it was incredible to behold,” she says, referring to the to the odd, feathery dwellers that call Antarctica home.

‘Kernel memory leaking’ Intel processor design flaw forces Linux, Windows redesign

A fundamental design flaw in Intel’s processor chips has forced a significant redesign of the Linux and Windows kernels to defang the chip-level security bug.

There were rumors of a severe hypervisor bug – possibly in Xen – doing the rounds at the end of 2017. It may be that this hardware flaw is that rumored bug: that hypervisors can be attacked via this kernel memory access cockup, and thus need to be patched, forcing a mass restart of guest virtual machines.

Windows 10 Bundles a Password Manager. Password Manager Bundles a Security Flaw

“This potential vulnerability requires a Keeper user to be lured to a malicious website while logged into the browser extension, and then fakes user input by using a ‘clickjacking’ technique to execute privileged code within the browser extension,” said Craig Lurey, co-founder and CTO of Keeper Security.

The Overwatch Videogame League Aims to Become the New NFL

Every major sport in the US has seen the average age of its viewership increase since 2000. The NBA’s average fan is 42. The average NFL fan is 50. The average MLB fan is 57. What’s more, these audiences are limited almost entirely to North America. The Overwatch League, meanwhile, will begin with nine US teams and three from abroad—Shanghai, Seoul, and London (with more, I’m told, on the way)—and its average fan is a demographically pleasing 21 years old.

Portugal’s internet shows us a world without net neutrality, and it’s ugly

Portugal isn’t the only country allowing tiering of internet services. In Britain, the internet service provider Vodaphone charges about $33 a month for basic service but offers several “passes” allowing unlimited video or music streaming, social media usage, or chat, at additional tariffs of up to $9.30 per month.
