Comment: Proposal: update the universal SPM constant. (Score 1) 289

According to Wikipedia, the widely-known 1.0 SPM constant was first proposed sometime in the mid-late 1800s, usually attributed to PT Barnum, but apparently falsely. Perhaps the murky origins of the constant explain why it has been forgotten by physics, or perhaps it's just that modern commerce has made it much easier to measure with accuracy.

To make it more SI, I propose we switch to Suckers Per Second, and that SPS should be updated from 60 (in the Barnum era) to a lower bound of 395 (ref: Apple Watch, "sport" edition) and upper bound of SBP=17,000.

The point of BTC is disintermediation. If you scratch the surface, you'll learn that everyone hates conventional banks, CC, etc - mainly because the intermediaries are extracting such a high toll. Yes, they are convenient enough to use, but just barely. The prospect of a secure, trust-free and cost-efficient way to buy directly, that's BTC's niche.

Apple Doubles MacBook Pro R/W Performance 204

Posted by samzenpus
from the greased-lightning dept.
Lucas123 writes Benchmark tests performed on the 2015 MacBook Pro revealed it does have twice the read/write performance as the mid-2014 model. Tests performed with the Blackmagic benchmark tool revealed read/write speeds of more than 1,300MBps/1,400MBps, respectively. So what's changed? The new MacBook Pro does have a faster Intel dual-core i7 2.9GHz processor and 1866MHz LPDDR3) RAM, but the real performance gain is in the latest PCIe M.2 flash module. The 2014 model used a PCIe 2.0 x2 card and the 2015 model uses a PCIe 3.0 x4 (four I/O lanes) card. Twice the lanes, twice the speed. While Apple uses a proprietary flash card made by Samsung, Intel, Micron and SanDisk are all working on similar technology, so it's likely to soon wind up in high-end PCs.

Microsoft's First Azure Hosted Service Is Powered By Linux 66

jones_supa (887896) writes "Canonical, through John Zannos, VP Cloud Alliances, has proudly announced that the first ever Microsoft Azure hosted service will be powered by Ubuntu Linux. This piece of news comes from the Strata + Hadoop World Conference, which takes place this week in California. The fact of the matter is that the news came from Microsoft who announced the preview of Azure HDInsight (an Apache Hadoop-based hosted service) on Ubuntu clusters yesterday at the said event. This is definitely great news for Canonical, as their operating system is getting recognized for being extremely reliable when handling Big Data. Ubuntu is now the leading cloud and scale-out Linux-based operating system."

Systemd Getting UEFI Boot Loader 471

Posted by Soulskill
from the one-module-among-many dept.
New submitter mrons writes: Many new features are coming for systemd. This includes the ability to do a full secure boot. As Lennart Poettering mentions in a Google+ comment: "This is really just about providing the tools to implement the full trust chain from the firmware to the host OS, if SecureBoot is available. ... Of course, if you don't have EFI SecureBoot, than nothing changes. Also if you turn it off, than nothing changes either. [sic]" Phoronix notes, "Gummiboot is a simple UEFI boot manager that's been around for a few years but only receives new work from time-to-time. Lennart and Kay Sievers are looking at adding Gummiboot to systemd to complete the safety chain of the boot process with UEFI Secure Boot. Systemd will communicate with this UEFI boot loader to ensure the system didn't boot into a compromised state."

Comment: just tax corp income where it's earned. (Score 1) 825

Most of these tax avoidance schemes depend on the fact that corps pay tax only on excess profits. They don't pay tax on income, like, you know, *people* do. Notice that it's always unambiguous where revenue from, so a corporate *income* tax would be relatively loophole-free. Yeah, yeah, we'd have to drop the rates substantially, since corps pay such a low effective tax (relative to revenue) today.

interesting that these density improvements could both be applied to tape as well.

yeah, "tape yuck", but it makes a certain amount of sense for cool data. which we have lots of, always increasing. tape seeks are a minute or so, and if density is competitive, tape has a good chance to beat disks on price. certainly on power. the real problem is that the tape industry seems to be sort of demographically challenged...

Imagine the amount of mayhem being tacitly supported by makers of paper and pens.

Politicians think they are right to demand control of behavior because it is, theoretically possible. They don't seem to appreciate that their model for the online world is flawed: it's not like physical space, compact and easily policed. The net is a communication medium, which can no more be policed than paper, phones or *air* can be cleaned of mayhem...

In a just universe, whenever some knob uttered a platitude like that, they'd be struck by lightning or a meteor or turned into a pillar of salt.

yes, I definitely would prefer a potentially secure wireless protocol over an obviously insecure physical key. this is a no-brainer! even better: make it a public, *STANDARD* secure wireless protocol, preferably exactly the same one I use to authorize NFC payments from my phone.
